Description

[0001] This utility model claims priority to utility model patent application No. 2024213976637, filed on June 18, 2024. Technical Field

[0002] This utility model relates to the field of auxiliary products for electronic terminals, and more specifically, to a multi-legged stand and an electronic terminal support device. Background Technology

[0003] Stands are mainly used to hold and support electronic devices such as tablets and mobile phones, making it convenient for them to take pictures. At present, there are many types of stands on the market, ranging from materials to functions. For example, there are multi-leg stands on the market, whose multiple legs can be adjusted to their opening degree.

[0004] Existing multi-leg brackets generally include a support rod assembly, a sliding sleeve assembly, at least three support foot assemblies, and at least three connecting rods. Each of the at least three connecting rods corresponds to one of the at least three support foot assemblies. The sliding sleeve assembly is slidably mounted on the support rod assembly along its length. One end of each support foot assembly is rotatably connected to the sliding sleeve, and the other end can be supported on a support surface. One end of each connecting rod is rotatably connected to the support rod assembly, and the other end is also rotatably connected to the support rod assembly. The sliding of the sliding sleeve assembly along the length of the support rod assembly adjusts the opening degree of the support foot assembly relative to the support rod assembly. Because the sliding of the sliding sleeve assembly relative to the support rod assembly causes the support foot assembly to open excessively during opening, it may lead to deformation of the connecting rods or support foot assemblies, thereby damaging the multi-leg bracket. Therefore, a multi-leg bracket is provided to solve the above problems. Utility Model Content

[0080] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can typically be arranged and designed in various different configurations.

[0081] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0082] Reference Figures 1-40 This utility model provides a multi-legged bracket for supporting an electronic terminal, including a support rod assembly 100, a sliding sleeve assembly 200, at least three support foot assemblies 300, and at least three connecting rods 400. The sliding sleeve assembly 200 is slidably sleeved on the support rod assembly 100. At least three support foot assemblies 300 are rotatably connected to the sliding sleeve assembly 200. At least three connecting rods 400 correspond to the at least three support foot assemblies 300 and are rotatably connected to the support rod assembly 100. The three connecting rods 400 are rotatably connected to the corresponding support foot assemblies 300, with each connecting rod 400 between the support rod assembly 100 and the corresponding support foot assembly 300; wherein, the sliding sleeve assembly 200 can slide along the extension direction of the support rod assembly 100 to adjust the degree of deployment of at least three support foot assemblies 300 relative to the support rod assembly 100; when at least three support foot assemblies 300 are deployed to their maximum deployment relative to the sliding sleeve assembly 200, the sliding sleeve assembly 200 abuts against the support rod assembly 100.

[0083] By abutting against the support rod assembly 100, the sliding stroke of the sliding sleeve assembly 200 relative to the support rod assembly 100 is limited, thereby limiting the opening degree of the support foot assembly 300 relative to the support rod assembly 100. This prevents the support foot assembly 300 from being over-opened, which would cause deformation of the connecting rod 400 and the support foot assembly 300, thus improving the service life of the multi-leg bracket.

[0084] For example only, the electronic terminal can be a mobile phone, tablet computer, camera, etc.

[0085] For example only, the support rod assembly 100 may be telescopic in its length direction or the support rod assembly 100 may be of a fixed length; for example, the support rod assembly 100 may include a plurality of telescopic joints, among which a first telescopic joint 111 may be included, and the sliding sleeve assembly 200 may be slidably sleeved on the first telescopic joint 111.

[0086] For illustrative purposes only, the number of support foot assemblies 300 may be 3, 4, etc., and the number of connecting rods 400 may be 3, 4, etc., with the number of connecting rods 400 being the same as the number of support foot assemblies 300.

[0087] Understandably, the sliding sleeve assembly 200, the support rod assembly 100, the support foot assembly 300, and the corresponding connecting rod 400 constitute a planar four-bar linkage mechanism. Specifically, the planar four-bar linkage mechanism can be a crank-slider mechanism, a rocker-slider mechanism, etc.

[0088] For illustrative purposes only, the support foot assembly 300 can be retracted into the support rod assembly 100. After the support foot assembly 300 is retracted into the support rod assembly 100, the connecting rod 400 is located between the support rod assembly 100 and the corresponding support foot assembly 300. With the support foot assembly 300 retracted into the support rod assembly 100, at least three support foot assemblies are available for the user to hold.

[0089] Understandably, the extension direction of the support rod assembly 100 is the length direction of the support rod assembly 100.

[0090] Reference Figure 17 ,as well as Figures 19-27The sliding sleeve assembly 200 includes a main component 230, a first component 210, and a second component 220. The main component 230 has a mounting cavity 201, and both the first component 210 and the second component 220 are fitted into the mounting cavity 201. The first component 210, the second component 220, and the main component 230 are fixed in pairs. The first component 210 is slidably fitted onto the support rod assembly 100, and the second component 220 is slidably fitted onto the support rod assembly 100. When at least three of the support leg assemblies 300 are fully extended relative to the sliding sleeve assembly 200, the second component 220 abuts against the support rod assembly 100. By slidably fitting the first component 210 and the second component 220 onto the support rod assembly 100, the sliding sleeve assembly 200 experiences less wobbling when sliding relative to the support rod assembly 100. When the multi-leg bracket is in a supported state, the sliding sleeve assembly 200 experiences less wobbling relative to the support rod assembly 100, resulting in more stable support for the multi-leg bracket. The sliding sleeve assembly 200 is configured as a main component 230, a first component 210, and a second component 220, which facilitates the manufacturing and installation of the sliding sleeve assembly 200. Since both the first component 210 and the second component 220 are fitted onto the main component 230, the sliding sleeve assembly 200 has a compact structure and occupies a small volume. Furthermore, the first component 210, the second component 220, and the main component 230 are fixed together in pairs, resulting in better overall structural strength and a better user experience for the sliding sleeve assembly 200.

[0091] For example, the first kit 210, the second kit 220, and the main kit 230 are in direct or indirect contact with each other.

[0092] Reference Figure 17 ,as well as Figures 19-27 The sliding sleeve assembly 200 further includes at least two first fasteners 240, which pass through the main assembly 230, the first assembly 210 and the second assembly 220 and are fastened together to fix the first assembly 210, the second assembly 220 and the main assembly 230 in pairs.

[0093] Understandably, the first fastener 240 passes through the main kit 230, the first kit 210 and the second kit 220 for fastening connection, which makes the structure of the sliding sleeve assembly 200 simple and easy to assemble; at least two first fasteners 240 can also restrict the circumferential rotation between the first kit 210, the second kit 220 and the main kit 230, thereby making the overall structural strength of the sliding sleeve assembly 200 better.

[0094] For example, the first kit 210 is in close contact with the second kit 220, and the main kit 230 is in close contact with the second kit 220, so that the first kit 210, the second kit 220, and the main kit 230 are fixed together.

[0095] For example, there are two first fasteners 240, which are located on opposite sides of the sliding sleeve assembly 200.

[0096] For example, the first fastener 240 can be a threaded fastener, a riveted fastener, etc.

[0097] See 17, and Figures 19-27 The first assembly 210 includes a first sleeve 211 and at least two connecting posts 212 protruding from the outer wall of the first sleeve 211. The first sleeve 211 is slidably sleeved on the support rod assembly 100, and the at least two connecting posts 212 correspond to at least two first fasteners 240 respectively. The second assembly 220 includes a second sleeve 221 and at least two connecting ears 222 protruding from the outer wall of the second sleeve 221. The at least two connecting ears 222 correspond to at least two first fasteners 240 respectively. The main assembly 230 includes a main sleeve 231 and a part protruding from the inner wall of the main sleeve 231. At least two connecting protrusions 232 on the wall, the connecting post 212 and the connecting ear 222 are both located in the mounting cavity 201, the connecting ear 222 is located between the connecting post 212 and the connecting protrusion 232, and at least two of the connecting protrusions 232 correspond to at least two of the first fasteners 240 respectively; the first fasteners 240 pass through the corresponding connecting protrusion 232 and the corresponding connecting ear 222 and are fastened to the corresponding connecting post 212, the connecting protrusion 232 is in tight contact with the corresponding connecting ear 222, and the connecting ear 222 is in tight contact with the corresponding connecting post 212.

[0098] Understandably, the connecting post 212 and the connecting ear 222 are both located within the mounting cavity 201 formed by the main sleeve 231, which makes the structure of the sliding sleeve assembly 200 compact, and the connecting post 212, connecting ear 222 and other structures are not easily damaged during the use of the multi-leg bracket.

[0099] Understandably, the connecting post 212, connecting ear 222, connecting protrusion 232 and other structures facilitate the insertion of the first fastener 240.

[0100] Reference Figure 17 ,as well as Figures 19-27The first fastener 240 includes a first head 241 and a first rod portion 242 connected to the first head 241. The first head 241 of the first fastener 240 is in tight contact with the corresponding connecting protrusion 232. The first rod portion 242 of the first fastener 240 passes through the corresponding connecting protrusion 232 and the corresponding connecting lug 222 and is threadedly connected to the connecting post 212. The first head 241 of the first fastener 240 protrudes from the bottom surface of the connecting protrusion 232. Alternatively, the connecting protrusion 232 has a receiving hole 202 that communicates with the bottom surface of the connecting protrusion 232, and the first head 241 of the first fastener 240 is received in the receiving hole 202.

[0101] Understandably, the first head 241 of the first fastener 240 protrudes from the bottom surface of the connecting protrusion 232 or is received in the receiving hole 202, making it less likely for the user to touch the first head 241 of the first fastener 240 during the use of the sliding sleeve assembly, thereby avoiding injury to the user's hand; furthermore, the first head 241 is hidden in the bottom surface of the connecting protrusion 232 or the receiving hole 202, making the multi-leg bracket more aesthetically pleasing in structure.

[0102] Understandably, "bottom" and "top" should be understood according to the common usage of multi-legged brackets. The common usage of multi-legged brackets is that the multi-legged brackets are supported on a support plane. The bottom end of a component refers to the end that is close to the support plane, the top end of a component refers to the end that is far away from the support plane, the bottom surface of a component refers to the side that is close to the support plane, and the top surface of a component refers to the side that is far from the support plane.

[0103] Understandably, the first head 241 of the first fastener 240 is in tight contact with the corresponding connecting protrusion 232, and the first rod portion 242 of the first fastener 240 passes through the corresponding connecting protrusion 232, the corresponding connecting lug 222 and is threadedly connected to the connecting post 212, so that the main kit 230, the first kit 210 and the second kit 220 are fixed together.

[0104] Reference Figure 17 ,as well as Figures 19-27The connecting protrusion 232 has a third connecting hole 203c, the connecting post 212 has a first connecting hole 203a, and the connecting lug 222 has a second connecting hole 203b. The first fastener 240 passes through the corresponding third connecting hole 203c and the corresponding second connecting hole 203b and is fastened to the first connecting hole 203a. The main assembly 230 has a first opening 204a communicating with the mounting cavity 201. The first assembly 210 is in a first mounting position in the mounting cavity 201, and the second assembly 220 is in a second mounting position in the mounting cavity 201. The second assembly 220 can be inserted into the second mounting position of the mounting cavity 201 through the first opening 204a, and the first assembly 210 can be inserted into the first mounting position of the mounting cavity 201 through the first opening 204a. The inner wall of the main sleeve 231 is recessed with at least two first... The groove 205, at least two first grooves 205 respectively correspond to at least two connecting ears 222; the connecting ear 222 has a first alignment portion 222a adapted to the corresponding first groove 205. During the process of the second kit 220 being inserted into the second mounting position of the mounting cavity 201 through the first opening 204a, the first alignment portion 222a cooperates with the corresponding first groove 205 to align the second connecting hole 203b with the corresponding third connecting hole 203c; the connecting post 212 has a second alignment portion 212a adapted to the corresponding first groove 205. During the process of the first kit 210 being inserted into the first mounting position of the mounting cavity 201 through the first opening 204a, the second alignment portion 212a cooperates with the corresponding first groove 205 to align the first connecting hole 203a with the corresponding second connecting hole 203b.

[0105] Understandably, the first groove 205 cooperates with the first alignment part 222a and the second alignment part 212a respectively, so that the second connecting hole 203b is aligned with the corresponding third connecting hole 203c, and the first connecting hole 203a is aligned with the corresponding second connecting hole 203b, which facilitates the installation of the first fastener 240 and thus facilitates the assembly of the sliding sleeve assembly 200.

[0106] Furthermore, the first groove 205 simultaneously aligns the first assembly 210 and the second assembly 220, simplifying the structure of the sliding sleeve assembly 200 and facilitating its manufacturing. Additionally, the first groove 205 engages with the first alignment portion 222a and the second alignment portion 212a, respectively, reducing the wobbling of the first assembly 210 relative to the main assembly 230 and the wobbling of the second assembly 220 relative to the main assembly 230, thereby improving the overall structural strength of the sliding sleeve assembly 200.

[0107] For example, the first groove 205 is a stretching groove, and the first groove 205 extends along the insertion direction of the first kit 210 (the first groove 205 extends along the insertion direction of the second kit 220). During the process of the second kit 220 being inserted into the second mounting position of the mounting cavity 201 through the first opening 204a, the first alignment part 222a slides along the first groove 205. During the process of the first kit 210 being inserted into the first mounting position of the mounting cavity 201 through the first opening 204a, the second alignment part 212a slides along the first groove 205.

[0108] Reference Figure 17 ,as well as Figures 19-27 The sliding sleeve assembly 200 has at least three first rotating portions, and the support foot assembly 300 has a second rotating portion 331. The second rotating portions 331 of the at least three support foot assemblies 300 are rotatably connected to their corresponding first rotating portions. The number of first fasteners 240 is at least three, and each first rotating portion is located between two adjacent first fasteners 240. The location of each first rotating portion between two adjacent first fasteners 240 improves the overall structural strength of the sliding sleeve assembly 200 and reduces deformation or shaking of the sliding sleeve assembly 200 caused by the force exerted by the support foot assembly 300. Clearly, the location of each first rotating portion between two adjacent connecting ears 222, between two adjacent connecting posts 212, and between two adjacent connecting protrusions 232 all contribute to better overall structural strength and a more compact structure of the sliding sleeve assembly 200.

[0109] Understandably, the number of first fasteners 240 is the same as the number of support foot assemblies 300.

[0110] For example, the first rotating part is a shaft and the second rotating part 331 is a hole, or the first rotating part is a hole and the second rotating part 331 is a shaft.

[0111] Reference Figure 17 ,as well as Figures 19-27Each of the connecting protrusions 232 is provided with a first rib 233 and a second rib 234. The first rib 233 is integrally connected to the main sleeve 231, and the second rib 234 is integrally connected to the main sleeve 231. Both the first rib 233 and the second rib 234 are accommodated in the mounting cavity 201. A first chamber 207a is formed between the first rib 233 of the connecting protrusion 232 and the second rib 234 of the same connecting protrusion 232. The connecting ear 222 is located in the corresponding first chamber 207a, and the connecting post 212 is located in the corresponding first chamber 207a. A second chamber 207b is formed between the first rib 233 of the connecting protrusion 232 and the second rib 234 of the adjacent connecting protrusion 232. The second rotating part 331 is a shaft, and the second rotating part 331 of the support foot assembly 300 is located in the second chamber 207b.

[0112] The second rotating part 331 includes a coaxial first shaft part 331a and a second shaft part 331b. The first shaft part 331a extends toward the corresponding first protruding rib 233, and the second shaft part 331b extends toward the corresponding second protruding rib 234. The second rotating part 331 is axially defined between the corresponding first protruding rib 233 and the corresponding second protruding rib 234.

[0113] Understandably, the first rib 233 and the second rib 234 increase the structural strength of the main assembly 230. Furthermore, the first rib 233 and the second rib 234 separate the first chamber 207a and the second chamber 207b, facilitating the assembly of the sliding sleeve assembly 200 and the installation of the support foot assembly 300 onto the sliding sleeve assembly 200. The fact that the connecting ear 222 and the connecting post 212 are both located in the first chamber 207a also contributes to the compact structure of the sliding sleeve assembly 200.

[0114] Understandably, positioning the second rotating part 331 axially between the corresponding first protruding rib 233 and the corresponding second protruding rib 234 reduces the axial wobble of the second rotating part 331 relative to the sliding sleeve assembly 200.

[0115] Understandably, the first chamber 207a is part of the mounting chamber 201.

[0116] Reference Figure 17 ,as well as Figures 19-27The second rotating part 331 is a shaft, comprising a coaxial first shaft part 331a and a second shaft part 331b, and is located within the mounting cavity 201. The first sleeve 211 has at least three protruding third ribs 213, each corresponding to one of the at least three second rotating parts 331, and is housed within the mounting cavity 201. Each third rib 213 has a first wall 206a, and the main assembly 230 has at least three second walls 206b. The first wall 206a and the corresponding second walls 206b together form a single unit. The first rotating hole 206 is provided, and the first shaft portion 331a is rotatably mounted in the first rotating hole 206. The first rotating portion includes the first rotating hole 206. The first sleeve 211 is provided with at least three fourth protruding ribs 214, each of which corresponds to at least three second rotating portions 331. The at least three fourth protruding ribs 214 are respectively housed in the mounting cavity 201. Each fourth protruding rib 214 has a third wall 208a. The main assembly 230 has at least three fourth walls 208b. The second rotating hole 208 is formed by the corresponding fourth wall body 208b and is coaxial with the first rotating hole 206. The second shaft part 331b is rotatably installed in the second rotating hole 208. The first rotating part includes the second rotating hole 208. The first end of the main assembly 230 has a first opening 204a, which communicates with the mounting cavity 201. The second end of the main assembly 230 has a second opening 204b, which communicates with the mounting cavity 201. The first assembly 210 is in the first mounting position of the mounting cavity 201. The second assembly 210 is in the first mounting position of the mounting cavity 201. 20 is in the second mounting position of the mounting cavity 201, and the second rotating part 331 is in the third mounting position of the mounting cavity 201. The second rotating part 331 can be inserted into the third mounting position of the mounting cavity 201 through the second opening 204b. After the second rotating part 331 is inserted into the third mounting position of the mounting cavity 201, the second kit 220 can be inserted into the second mounting position of the mounting cavity 201 through the first opening 204a. After the second kit 220 is inserted into the second mounting position of the mounting cavity 201, the first kit 210 can be inserted into the first mounting position of the mounting cavity 201 through the first opening 204a.

[0117] Understandably, the third rib 213 and the fourth rib 214 improve the structural strength of the first sleeve 211. The third rib 213, combined with the main assembly 230, forms the first rotating hole 206, and the fourth rib 214, combined with the main assembly 230, forms the second rotating hole 208, facilitating the installation of the support foot assembly 300 onto the sliding sleeve assembly 200 and also facilitating the assembly of the sliding sleeve assembly 200. Furthermore, the first shaft portion 331a is rotatably mounted in the first rotating hole 206, and the second shaft portion 331b is rotatably mounted in the second rotating hole 208, making the rotation of the second rotating portion 331 more stable.

[0118] Understandably, the first opening 204a and the second opening 204b facilitate the installation of the second rotating part 331, the second kit 220, and the first kit 210 on the main kit 230. The second rotating part 331, the second kit 220, and the first kit 210 are installed on the main kit 230 in a certain order, which facilitates the installation of the support foot assembly 300 on the sliding sleeve assembly 200.

[0119] Understandably, in the first mounting position of the mounting cavity 201, the connecting post 212 is in the first chamber 207a of the first assembly 210; in the second mounting position of the mounting cavity 201, the connecting ear 222 is in the first chamber 207a of the second assembly 220; and in the third mounting position of the mounting cavity 201, the second rotating part 331 is in the second chamber 207b of the second assembly 220.

[0120] Understandably, when the sliding sleeve assembly 200 is assembled, the first kit 210 is in the first mounting position of the mounting cavity 201, the second kit 220 is in the second mounting position of the mounting cavity 201, and the second rotating part 331 is in the third mounting position of the mounting cavity 201.

[0121] For example, the first wall 206a is at least partially a surface of revolution, the second wall 206b is at least partially a surface of revolution, the third wall 208a is at least partially a surface of revolution, and the fourth wall 208b is at least partially a surface of revolution, wherein the surface of revolution can be a cylindrical surface, a conical surface, a spherical surface, etc.

[0122] For example, the first wall 206a and the corresponding second wall 206b form a first rotating hole 206 in a fully enclosed or partially enclosed manner; the third wall 208a and the corresponding fourth wall 208b form a second rotating hole 208 in a fully enclosed or partially enclosed manner.

[0123] Reference Figure 17 ,as well as Figures 19-27The third protruding rib 213 is located between the main sleeve 231 and the first sleeve 211, and the third protruding rib 213 mates with the inner wall of the main sleeve 231; the fourth protruding rib 214 is located between the main sleeve 231 and the first sleeve 211, and the fourth protruding rib 214 mates with the inner wall of the main sleeve 231; the connecting post 212 is located between the main sleeve 231 and the first sleeve 211, and the connecting post 212 mates with the inner wall of the main sleeve 231.

[0124] Understandably, the third rib 213, the fourth rib 214, and the connecting main sleeve all cooperate with the inner wall of the main sleeve 231, which makes the overall structural strength of the sliding sleeve assembly 200 better. The main sleeve 230 is limited by the first sleeve 210. During use, the main sleeve 230 has less shaking relative to the first sleeve 210, and the main sleeve 230 undergoes less deformation.

[0125] Understandably, the connecting post 212 is located between an adjacent set of third ribs 213 and fourth ribs 214.

[0126] For example, fits include interference fits, clearance fits, and transition fits.

[0127] Reference Figure 17 ,as well as Figures 19-27 The main assembly 230 is provided with a slot 209, and the first assembly 210 is provided with an insert 215 adapted to the slot 209. The insert 215 is inserted into the slot 209 and is located within the mounting cavity 201. The number of slots 209 is at least three, and the number of inserts 215 is at least three. The main sleeve 231 has at least three first cylindrical portions 231a, which are connected sequentially. 1a extends from one end of the main sleeve 231 to the other end. At least three first cylindrical portions 231a correspond to at least three support foot assemblies 300 respectively. Each first cylindrical portion 231a is provided with a relief groove 2010. The support foot assembly 300 extends into the corresponding relief groove 2010 and can swing in the corresponding relief groove 2010. The first cylindrical portion 231a is also provided with a first protrusion 231b. The slot 209 is provided on the first protrusion 231b.

[0128] Understandably, inserting the insert 215 into the slot 209 improves the overall structural strength of the sliding sleeve assembly 200, makes the main component 230 fit more tightly with the first component 210, and makes the main component 230 less prone to deformation during use due to the constraint of the first component 210.

[0129] Understandably, since the first cylindrical portion 231a has a relief groove 2010, and the first cylindrical portion 231a also has a first protrusion 231b, the structural strength of the first cylindrical portion 231a is improved, and the structural strength of the main assembly 230 is not significantly reduced due to the relief groove 2010.

[0130] For example, each of the inserts 215 is located between two adjacent first fasteners 240.

[0131] For example, insert 215 mates with the inner wall of main sleeve 231.

[0132] For example, the main sleeve 231 is a rotating body, and the first cylindrical part 231a is a partially rotating body. For instance, the main sleeve 231 is a cylindrical tube, and the first cylindrical part 231a is a partially cylindrical tube.

[0133] Reference Figure 17 ,as well as Figures 19-27 The sliding sleeve assembly 200 has a first rotating part that rotatably engages with the support foot assembly 300, and the support foot assembly 300 has a second rotating part 331. The first rotating part is a hole, and the second rotating part 331 is a shaft. The second rotating part 331 is located in the mounting cavity 201. The first kit 210 and the main kit 230 are combined to form the first rotating part. The first end of the main kit 230 has a first opening 204a that communicates with the mounting cavity 201, and the second end of the main kit 230 has a second opening 204b that communicates with the mounting cavity 201. The first kit 210 is located in the mounting cavity 201. The second assembly 220 is in the first mounting position of the mounting cavity 201, and the second rotating part 331 is in the third mounting position of the mounting cavity 201. The second rotating part 331 can be inserted into the third mounting position of the mounting cavity 201 through the second opening 204b. After the second rotating part 331 is inserted into the third mounting position of the mounting cavity 201, the second assembly 220 can be inserted into the second mounting position of the mounting cavity 201 through the first opening 204a. After the second assembly 220 is inserted into the second mounting position of the mounting cavity 201, the first assembly 210 is inserted into the first mounting position of the mounting cavity 201 through the first opening 204a.

[0134] Understandably, the second rotating part 331, the second kit 220, and the first kit 210 are sequentially installed into the main kit 230. The first kit 210 and the second kit 220 are combined to form the first rotating part, which facilitates the installation of the second rotating part 331 into the first rotating part. The sequential installation of the second rotating part 331, the second kit 220, and the first kit 210 into the main kit 230 also facilitates the assembly of the sliding sleeve assembly 200.

[0135] Reference Figure 17 ,as well as Figures 19-27 The sliding sleeve assembly 200 has at least three first rotating parts, and at least three support foot assemblies 300 are rotatably connected to the corresponding first rotating parts. There are at least three first fasteners 240, with each first rotating part located between two adjacent first fasteners 240. The location of each first rotating part between two adjacent first fasteners 240 improves the overall structural strength of the sliding sleeve assembly 200 and reduces deformation or shaking of the sliding sleeve assembly 200 caused by the force exerted by the support foot assemblies 300.

[0136] Reference Figure 17 The first fastener 240 includes a first head 241 and a first rod portion 242 connected to the first head 241. The first head 241 of the first fastener 240 is in tight contact with the main assembly 230. The first rod portion 242 of the first fastener 240 passes through the main assembly 230 and is threadedly connected to the second assembly 220 and the first assembly 210. When the multi-leg bracket is supported on a support plane, the orthographic projection of the main assembly 230 on the support plane is a first projection, and the orthographic projection of the first head 241 of the first fastener 240 on the support plane is a second projection. The first projection covers the second projection.

[0137] Understandably, the above arrangement places the main component 230 above the first head 241 of the first fastener 240, making it less likely for the user to touch the head of the first fastener 240 during the use of the sliding sleeve assembly 200, thereby preventing the first head 241 from injuring the user's hand. Furthermore, the main component 230 visually obscures the first head 241, making the sliding sleeve assembly 200 more aesthetically pleasing in structure.

[0138] Reference Figure 1 , Figure 15 , Figure 18 The second assembly 220 includes a second sleeve 221, which is slidably fitted onto the support rod assembly 100. The first end of the second sleeve 221 is located in the mounting cavity 201, and the second end of the second sleeve 221 is outside the mounting cavity 201. When at least three of the support foot assemblies 300 are fully extended relative to the sliding sleeve assembly 200, the second end of the second sleeve 221 abuts against the support rod assembly 100. One end of the connecting rod 400 is rotatably connected to the support rod assembly 100, and the other end is rotatably connected to the corresponding support foot assembly 300. The length of the second sleeve 221 is greater than or equal to 60% of the length of the connecting rod 400.

[0139] The length of the second sleeve 221 is greater than or equal to 60% of the length of the connecting rod 400, making the sliding sleeve assembly 200 slide more stably relative to the support rod assembly 100; and, when the multi-leg bracket is in the supported state, the sliding sleeve assembly 200 wobbles less relative to the support rod assembly 100.

[0140] Reference Figure 1 , Figure 15 , Figure 17 , Figure 18 The sliding sleeve assembly 200 has at least three first rotating parts, and at least three support foot assemblies 300 are rotatably connected to the corresponding first rotating parts. The sliding sleeve assembly 200 has a sliding cavity 2011 that is slidably adapted to the support rod assembly 100, and both ends of the sliding cavity 2011 extend away from the first rotating parts. The sliding sleeve assembly 200 has an abutting end for abutting against the support rod assembly 100, and one end of the sliding cavity 2011 extends to the abutting end. One end of the connecting rod 400 is rotatably connected to the support rod assembly 100, and the other end is rotatably connected to the corresponding support foot assembly 300. Along the sliding sleeve assembly 200... The length from the axis of the first rotating part to the abutting end in the sliding direction of 0 is the first length, which is greater than or equal to 60% of the length of the connecting rod 400; the length of the sliding cavity 2011 along its sliding direction is the second length, which is greater than or equal to 70% of the length of the connecting rod 400; in the state where the sliding sleeve assembly 200 abuts against the support rod assembly 100, the support rod assembly 100 has a first bottom 100a protruding from the bottom end of the sliding sleeve assembly 200, and the length of the first bottom 100a along the sliding direction of the sliding sleeve assembly 200 is the third length, which is less than or equal to 10% of the length of the connecting rod 400.

[0141] Understandably, the two ends of the sliding cavity 2011 extend away from the first rotating part. On the one hand, this makes the sliding cavity 2011 have better sliding stability along the support rod assembly 100. On the other hand, when the multi-leg bracket is in the supported state, there is less wobbling between the sliding sleeve assembly 200 and the support rod assembly 100, and the support is more stable.

[0142] Understandably, the second length of the sliding cavity 2011 is greater than or equal to 70% of the length of the connecting rod 400, which makes the sliding stability of the sliding sleeve assembly 200 along the support rod assembly 100 better, and when the multi-leg bracket is in the supported state, there is less wobbling between the sliding sleeve assembly 200 and the support rod assembly 100, and the support is more stable.

[0143] For example, the sliding cavity 2011 is clearance-fitted with the support rod assembly 100.

[0144] Understandably, the sliding cavity 2011 extends to the first assembly 210 and the second assembly 220. The sliding cavity 2011 includes a first sliding sub-cavity and a second sliding sub-cavity that are in communication with each other. The first sliding sub-cavity is slidably adapted to the support rod assembly 100, and the second sliding sub-cavity is slidably adapted to the support rod assembly 100. The first sliding sub-cavity is located in the first assembly 210, and the second sliding sub-cavity is located in the second assembly 220.

[0145] For example, the sliding cavity 2011 has a first cavity wall that slides with the support rod assembly 100, the first cavity wall surrounding the support rod assembly 100 in its entirety or in part.

[0146] Understandably, the third length is less than or equal to 10% of the length of the connecting rod 400. When the sliding sleeve assembly 200 is in contact with the support rod assembly 100, the sliding sleeve assembly 200 is brought as close as possible to the bottom end of the support rod assembly 100. This makes the structure of the support rod assembly 100 and the sliding sleeve assembly 200 more compact, and also makes it easier to set the second length of the sliding cavity 2011 to be greater than or equal to 70% of the length of the connecting rod 400.

[0147] For example, the first bottom 100a is part of the mounting member 120, that is, when the sliding sleeve assembly 200 is in contact with the support rod assembly 100, the mounting member 120 has a first bottom 100a protruding from the bottom end of the sliding sleeve assembly 200.

[0148] Reference Figure 18 The support rod assembly 100 includes a support rod body 110 and a mounting member 120. The mounting member 120 is installed at the bottom end of the support rod body 110. Each connecting rod 400 is rotatably connected to the mounting member 120. When at least three support foot assemblies 300 are fully extended relative to the sliding sleeve assembly 200, the sliding sleeve assembly 200 abuts against the mounting member 120. Setting the support rod assembly 100 in the structure of a support rod body 110 and mounting member 120 facilitates the manufacturing and installation of the support rod assembly 100. Furthermore, the mounting member 120 serves both to abut against the sliding sleeve assembly 200 and to rotatably connect the connecting rods 400, resulting in a compact structure and small footprint for the support rod assembly 100.

[0149] Reference Figure 18 , Figure 27The mounting component 120 includes a mounting post 121 and a mounting protrusion 122 connected to the mounting post 121. Each connecting rod 400 is rotatably connected to the mounting protrusion 122 of the mounting component 120. The support rod body 110 has a mounting hole 101 extending to its bottom end. The mounting post 121 is inserted into the mounting hole 101. The support rod assembly 100 also includes a second fastener 130, which passes through the support rod body 110 and is fastened to the mounting post 121. The sliding sleeve assembly 200 has a sliding cavity 2011 that is slidably adapted to the support rod assembly 100. A sliding strip 250 protrudes from the inner wall of the sliding cavity 2011 and extends along the sliding direction of the sliding cavity 2011. The outer side of the support rod body 110... The wall is recessed with a sliding groove 102, which is adapted to the sliding strip 250. During the sliding of the sliding sleeve assembly 200 along the extension direction of the support rod assembly 100, the sliding strip 250 slides in the sliding groove 102. The second fastener 130 includes a second head 131 and a second rod portion 132 connected to the second head 131. The second head 131 is accommodated in the sliding groove 102, and the second rod portion 132 passes through the support rod body 110 and is fastened to the mounting post 121. When the sliding sleeve assembly 200 is in contact with the support rod assembly 100, the second head 131 is accommodated in the sliding cavity 2011, and the second head 131 is located between the bottom end of the sliding strip 250 and the bottom end of the sliding sleeve assembly 200.

[0150] Understandably, the second fastener 130 securely connects the mounting post 121 to the support rod body 110, making it difficult for the mounting post 121 to detach from the support rod body 110. The second fastener 130 can be a threaded fastener, a riveted fastener, or the like.

[0151] Understandably, the cooperation between the sliding bar 250 and the sliding groove 102 makes the sliding sleeve assembly 200 slide more stably relative to the support rod assembly 100.

[0152] Understandably, by housing the second head 131 within the sliding groove 102, the possibility of the second head 131 scratching the user is reduced. On the other hand, the sliding groove 102 is used both to cooperate with the sliding bar 250 and to house the second head 131, making the structure of the support rod assembly 100 compact.

[0153] Understandably, when the sliding sleeve assembly 200 is in contact with the support rod assembly 100, the second head 131 is located between the bottom end of the sliding bar 250 and the bottom end of the sliding sleeve assembly 200, thus preventing the second head 131 from obstructing the sliding of the sliding sleeve assembly 200; and the second head 131 is housed in the sliding cavity 2011, further preventing the second head 131 from scratching the user's hand.

[0154] For example, there are two sliding bars 250, which are located on opposite sides of the sliding cavity 2011; there are two sliding grooves 102, which are located on opposite sides of the support rod body 110; there are two second fasteners 130, and the second heads 131 of the two second fasteners 130 are respectively housed in the two sliding grooves 102.

[0155] For example, the slider 250 is provided on the second sleeve 221 and / or the first sleeve 211.

[0156] For example, when the sliding sleeve assembly 200 is in contact with the mounting member 120, the sliding sleeve assembly 200 is in contact with the mounting protrusion 122.

[0157] Understandably, both the sliding bar 250 and the sliding groove 102 extend along the sliding direction of the sliding sleeve assembly 200.

[0158] For example, the support rod assembly 100 has a third rotating part 103, and the connecting rod 400 has a fourth rotating part 410. The third rotating part 103 is a hole, and the fourth rotating part 410 is a shaft, or the third rotating part 103 is a shaft and the fourth rotating part 410 is a hole.

[0159] For example, the support foot assembly 300 has a fifth rotating part 3010, and the connecting rod 400 has a sixth rotating part 420. The fifth rotating part 3010 is a hole, and the sixth rotating part 420 is a shaft, or the fifth rotating part 3010 is a shaft and the sixth rotating part 420 is a hole.

[0160] For example, the mounting member 120 includes a first mounting sub-member 120a and a second mounting sub-member 120b, the second mounting sub-member 120b being mounted on the first mounting sub-member 120a. The first mounting sub-member 120a includes a mounting post 121 and a portion of a mounting protrusion 122. The second mounting sub-member 120b includes a portion of the mounting protrusion 122 and is mounted on the first mounting sub-member 120a to form the mounting protrusion 122. When the sliding sleeve assembly 200 abuts against the mounting member 120, the sliding sleeve assembly 200 abuts against the first mounting sub-member 120a. Specifically, the second mounting sub-component 120b is mounted to the first mounting sub-component 120b via a third fastener 120c, which can be a threaded component, a riveted component, etc.; the third rotating part 103 is a hole, and the first mounting sub-component 120a and the second mounting sub-component 120b are combined to form the third rotating part 103. The advantage of this arrangement is that it facilitates the rotatable mounting of the connecting rod 400 to the support rod assembly 100. For example, one way to install the connecting rod 400 is to place the connecting rod 400 between the first mounting sub-component 120a and the second mounting sub-component 120b, and then mount the second mounting sub-component 120b to the first mounting sub-component 120a via the third fastener 120c.

[0161] Reference Figure 17 , 24 The multi-leg bracket, including models 25, 28-30, etc., further includes a locking structure 500. The locking structure 500 includes a locking ring 510 and a locking sleeve 520. The locking ring 510 is fitted onto the support rod assembly 100, and the locking sleeve 520 is fitted onto the support rod assembly 100. The locking sleeve 520 is threadedly connected to the sliding sleeve assembly 200. The locking ring 510 has a first conical surface 501, the locking sleeve 520 has a second conical surface 502, and the locking ring 510 has a third conical surface 503. The sliding sleeve assembly 200 has a fourth conical surface 2012. During the threaded engagement of the locking sleeve 520 with the sliding sleeve assembly 200, the second conical surface 502 presses against the first conical surface 501 to cause the locking ring 510 to grip the support rod assembly 100, and the fourth conical surface 2012 presses against the third conical surface 503 to cause the locking ring 510 to grip the support rod assembly 100.

[0162] Understandably, the locking ring 510 of the locking structure 500 grips the support rod assembly 100, the second conical surface 502 presses against the first conical surface 501 and the fourth conical surface 2012 presses against the third conical surface 503, and the locking sleeve 520 is threadedly connected to the sliding sleeve assembly 200. The locking structure 500 locks the sliding sleeve assembly 200 to the support rod assembly 100, reducing the swaying of the sliding sleeve assembly 200 relative to the support rod assembly 100. When the multi-leg bracket is in the supported state, the swaying of the sliding sleeve assembly relative to the support rod assembly is minimal, enabling the multi-leg bracket to...

[0163] Understandably, the locking ring 510 has a first conical surface 501 and a third conical surface 503, which allows the locking ring 510 to hold the support rod assembly 100 more tightly.

[0164] Understandably, during the threaded engagement of the locking sleeve 520 with the sliding sleeve assembly 200, the movement of the locking sleeve 520 can be decomposed into two parts: the locking sleeve 520 makes a linear movement toward the sliding sleeve assembly 200, and the locking sleeve 520 makes a rotational movement around the sliding sleeve assembly 200. The locking sleeve 520 makes a linear movement toward the sliding sleeve assembly 200, and the locking ring 510 is confined between the locking sleeve 520 and the sliding sleeve assembly 200, thereby causing the second conical surface 502 to press against the first conical surface 501, and causing the fourth conical surface 2012 to press against the third conical surface 503. During the process of the second conical surface 502 pressing against the first conical surface 501, the locking ring 510 deforms radially inward to grip the support rod assembly 100. During the process of the fourth conical surface 2012 pressing against the third conical surface 503, the locking ring 510 deforms radially inward to grip the support rod assembly 100.

[0165] More specifically, during the threaded engagement of the locking sleeve 520 with the sliding sleeve assembly 200, the locking sleeve 520 moves toward the sliding sleeve assembly 200, the locking sleeve 520 presses against the locking ring 510, and the locking ring 510 presses against the sliding sleeve assembly 200, thereby causing the second conical surface 502 to squeeze the first conical surface 501, and causing the fourth conical surface 2012 to squeeze the third conical surface 503.

[0166] For example, the first sleeve 210 of the sliding sleeve assembly 200 has a fourth sleeve 216 connected to the first sleeve 211 (e.g., integrated connection), the fourth sleeve 216 has external threads, the locking sleeve 520 has internal threads and is threadedly connected to the fourth sleeve 216, the locking ring 510 is fitted on the fourth sleeve 216, and the fourth conical surface 2012 is provided on the first sleeve 211.

[0167] For example, the first conical surface 501 and the third conical surface 503 are arranged at intervals.

[0168] For example, the fourth sleeve 216 mates with the inner wall of the main sleeve 231, the third protruding rib 213 is connected to the fourth sleeve 216 (e.g., integrated connection), the fourth protruding rib 214 is connected to the fourth sleeve 216 (e.g., integrated connection), the insert 215 is connected to the fourth sleeve 216 (e.g., integrated connection), and the connecting post 212 is connected to the fourth sleeve 216 (e.g., integrated connection).

[0169] Reference Figure 17 , 2425, 28-30, etc., with the first direction being from the top end to the bottom end of the locking ring 510, the cone diameter of the first conical surface 501 gradually increases along the first direction, the cone diameter of the second conical surface 502 gradually increases along the first direction, the cone diameter of the third conical surface 503 gradually decreases along the first direction, and the cone diameter of the fourth conical surface 2012 gradually decreases along the first direction; the first conical surface 501 extends to the top end of the locking ring 510, and the third conical surface 503 extends to the bottom end of the locking ring 510; the locking ring 510 is also provided with a first gap 504, the first gap 504 extends from the inner wall of the locking ring 510 to the outer wall of the locking ring 510, and the first gap 504 extends from the top end of the locking ring 510 to the bottom end of the locking ring 510. During the process of the locking ring 510 clamping the support rod assembly 100, the width of the first gap 504 decreases.

[0170] Understandably, the cone diameter of the first conical surface 501 gradually increases along the first direction, and the cone diameter of the second conical surface 502 gradually increases along the first direction, so that during the process of the second conical surface 502 pressing the first conical surface 501, the locking ring 510 deforms radially inward, thereby causing the locking ring 510 to deform radially inward. The cone diameter of the third conical surface 503 gradually decreases along the first direction, and the cone diameter of the fourth conical surface 2012 gradually decreases along the first direction, so that during the process of the fourth conical surface 2012 pressing the third conical surface 503, the locking ring 510 deforms radially inward.

[0171] Understandably, the first gap 504 extends from the inner wall of the locking ring 510 to the outer wall of the locking ring 510, and the first gap 504 extends from the top end of the locking ring 510 to the bottom end of the locking ring 510, so that the locking ring 510 can deform radially inward, thereby the locking ring 510 gripping the support rod assembly 100.

[0172] Understandably, as the locking ring 510 grips the support rod assembly 100, the width of the first gap 504 decreases.

[0173] For example, the first gap 504 extends along a straight line or along a curve.

[0174] Reference Figure 1 , Figure 2 , Figure 5 ,or Figures 31 to 47 The support foot assembly 300 includes a support foot body 300a and a magnetic 340, wherein the magnetic 340 is mounted on the support foot body 300a.

[0175] The support foot body 300a is rotatably connected to the sliding sleeve assembly 200, and the connecting rod 400 is rotatably connected to the support foot body 300a of the corresponding support foot assembly 300. At least three support foot assemblies 300 can be retracted into the support rod assembly 100. During the process of at least three support foot assemblies 300 retracting into the support rod assembly 100, the magnetic attractor 340 magnetically attracts the corresponding connecting rod 400 to promote the retraction of the at least three support foot assemblies 300 into the support rod assembly 100. In the state where at least three support foot assemblies 300 are retracted into the support rod assembly 100, the connecting rod 400 is located between the support rod assembly 100 and the corresponding support foot assembly 300, and the magnetic attractor 340 magnetically attracts the corresponding connecting rod 400 to keep the at least three support foot assemblies 300 in the state of being retracted into the support rod assembly 100.

[0176] Understandably, the magnetic 340 can facilitate the folding of the support leg assembly 300 into the support rod assembly 100, thereby making it easier to store the multi-legged bracket; and the magnetic 340 attracts the connecting rod 400 so that the support leg assembly 300 can remain in the folded state into the support rod assembly 100.

[0177] For example, the magnetic accumulator 340 is made of a permanent magnet material, such as an AlNiCo permanent magnet alloy, an IronChromiumCo permanent magnet alloy, a permanent magnet ferrite, a rare earth permanent magnet material, and a composite permanent magnet material.

[0178] For example, the connecting rod 400 is at least partially made of a soft magnetic material, such as cast iron, silicon steel, carbon steel, alloy steel, or soft magnetic ferrite. The connecting rod 400 includes a soft magnetic body and a plating layer, the soft magnetic body being made of the soft magnetic material and the plating layer being attached to the soft magnetic body.

[0179] Among the optional implementation methods, refer to Figure 5 The support leg body 300a has a slot 301, and the magnetic accumulator 340 is engaged in the slot 301. Engaging the magnetic accumulator 340 in the slot 301 facilitates its installation.

[0180] Among the optional implementation methods, refer to Figure 5The slot 301 is located inside the support leg body 300a. The support leg body 300a has a first mounting opening 302 communicating with the slot 301. The magnetic chuck 340 can be inserted into the slot 301 by clamping the first mounting opening 302. When the multi-leg bracket is supported on a support plane, the weight of the magnetic chuck 340 causes it to tend to move away from the first mounting opening 302. The advantage of this design is that it prevents the magnetic chuck 340 from coming out of the slot 301 of the support leg body 300a during the use of the multi-leg bracket.

[0181] For example, when the multi-legged bracket is supported on a support plane, the first mounting opening 302 is located above the slot 301.

[0182] Among the optional implementation methods, refer to Figure 32 , Figure 33 , Figure 42 The support foot assembly 300 includes a first support member 310 and a second support member 320, with the second support member 320 fitted onto the first support member 310. A magnetic chuck 340 is located between the second support member 320 and the first support member 310. The magnetic chuck 340, positioned between the second support member 320 and the first support member 310, prevents the magnetic chuck 340 from easily detaching from the support foot assembly 300.

[0183] Furthermore, referring to Figures 32-41 The second support member 320 has a mounting groove 303 and a second mounting opening 304, the second mounting opening 304 communicating with the mounting groove 303. Before the second support member 320 is fitted onto the first support member 310, the magnetic chuck 340 can be inserted into the mounting groove 303 through the second mounting opening 304. After the second support member 320 is fitted onto the first support member 310, the first support member 310 closes the second mounting opening 304. The second mounting opening 304 facilitates the installation of the magnetic chuck 340 onto the support foot assembly 300.

[0184] For example, the first support member 310 is provided with an assembly cavity 305, and the first end of the first support member 310 is provided with a first insertion opening 306a. The first insertion opening 306a communicates with the assembly cavity 305. The second support member 320 is inserted into the assembly cavity 305 of the first support member 310 through the first insertion opening 306a, so that the second support member 320 is fitted onto the first support member 310.

[0185] Furthermore, referring to Figure 32-41The support foot assembly 300 includes a third support member 330, which is sleeved on the first support member 310. A second support member 320 can be inserted into the first support member 310 from its first end, and the third support member 330 can be inserted into the first support member 310 from its second end. The third support member 330 is rotatably connected to the sliding sleeve assembly 200, and the second support member 320 is rotatably connected to a corresponding connecting rod 400. Clearly, the second support member 320 can detach from the first support member 310 from its first end, and the third support member 330 can detach from the first support member 310 from its second end.

[0186] For example, the second end of the first support member 310 is provided with a second insertion opening 306b, which is connected to the assembly cavity 305. The second support member 320 is inserted into the assembly cavity 305 of the first support member 310 through the second insertion opening 306b, so that the third support member 330 is fitted onto the first support member 310.

[0187] For example, the first support member 310 is made of a profile, such as an aluminum alloy profile.

[0188] Understandably, the support foot assembly 300 is configured as a structure consisting of a first support member 310, a second support member 320, and a third support member 330. The second support member 320 can be inserted into the first support member 310, and the third support member 330 can be inserted into the first support member 310, which facilitates the assembly of the support foot assembly 300. Furthermore, the third support member 330 is rotatably connected to the sliding sleeve assembly 200, and the second support member 320 is rotatably connected to the corresponding connecting rod 400, which facilitates the installation of the support foot assembly 300 on the multi-leg bracket.

[0189] For illustrative purposes only, one method of installing the support foot assembly 300 is as follows: first, the third support member 330 is rotatably connected to the sliding sleeve assembly 200, and the second support member 320 is rotatably connected to the connecting rod 400; then, the third support member 330 is inserted into the first support member 310, and the second support member 320 is inserted into the first support member 310; finally, the end of the connecting rod 400 away from the support foot assembly 300 is rotatably installed into the support rod assembly 100.

[0190] Among the optional implementation methods, refer to Figure 32-41The second support member 320 is provided with a first engaging portion 321, and the third support member 330 is provided with a second engaging portion 332. The first engaging portion 321 engages with the second engaging portion 332. The first engaging portion 321 has an engaging protrusion, and the second engaging portion 332 has an engaging groove; alternatively, the first engaging portion 321 has an engaging groove, and the second engaging portion 332 has an engaging protrusion. The second support member 320 has a first limiting protrusion, and the third support member 330 has a second limiting protrusion. The first support member 310 is restricted to be located between the first limiting protrusion and the second limiting protrusion so that the first support member 310 cannot slide relative to the integral structure formed by the second support member 320 and the third support member 330. The first latching part 321 and the second latching part 332 latch each other, so that the second support member 320 and the third support member 330 are as a whole, and the first support member 310 is restricted between the first limiting protrusion and the second limiting protrusion, so that the second support member 320 and the third support member 330 as a whole cannot slide relative to the first support member 310, thereby making the support foot assembly 300 more integral, the support foot assembly 300 less prone to shaking, and the multi-leg bracket more stable when supporting electronic terminals.

[0191] In some other implementations, the friction between the second support 320 and the first support 310 restricts the second support 320 from being mounted on the first support 310, and the friction between the third support 330 and the first support 310 restricts the third support 330 from being mounted on the first support 310.

[0192] Among the optional implementation methods, refer to Figure 31 , Figures 42-47Etc., one of the support foot components 300 is an auxiliary support foot component 300, which further includes a third support member 330. The third support member 330 of the auxiliary support foot component 300 is sleeved on the first support member 310 of the auxiliary support foot component 300. The third support member 330 of the auxiliary support foot component 300 can be inserted into the first support member 310 of the auxiliary support foot component 300. The third support member 330 of the auxiliary support foot component 300 has an assembly protrusion 333, and the assembly protrusion 333 is provided with an assembly groove 309. The mounting slot 309 is used to install auxiliary accessories. The first support member 310 of the auxiliary support foot assembly 300 is provided with a second clearance opening 308. During the process of the third support member 330 of the auxiliary support foot assembly 300 being inserted into the first support member 310 of the auxiliary support foot assembly 300, the second clearance opening 308 avoids the mounting protrusion 333. When the third support member 330 of the auxiliary support foot assembly 300 is fitted onto the first support member 310 of the auxiliary support foot assembly 300, the mounting protrusion 333 is accommodated in the second clearance opening 308. It can be understood that by providing the mounting slot 309 on the mounting protrusion 333 of the third support member 330, and by accommodating the mounting protrusion 333 in the second clearance opening 308, the auxiliary support foot assembly 300 has a compact structure and occupies a small volume. Furthermore, the second clearance opening 308 of the first support member 310 is used to avoid the mounting protrusion 333 during assembly, thereby facilitating the installation of the third support member 330 onto the first support member 310.

[0193] For example, the auxiliary accessories can be remote controls, cameras, etc., and preferably, the auxiliary accessories are remote controls that communicate with electronic terminals.

[0194] Among the optional implementation methods, refer to Figure 40 , Figure 45 The second support member 320 is rotatably connected to the corresponding connecting rod 400. The first support member 310 has a first clearance opening 307, allowing the second support member 320 to be inserted into or detached from the first support member 310. During the insertion or detachment of the second support member 320 from the first support member 310, the first clearance opening 307 avoids the connecting rod 400. When the second support member 320 is fitted onto the first support member 310, the connecting rod 400 is rotatably connected to the corresponding second support member 320 via the first clearance opening 307. The rotatable connection of the connecting rod 400 to the second support member 320 via the first clearance opening 307 makes the multi-leg bracket structure compact. Furthermore, the first clearance opening 307 also prevents the connecting rod 400 from obstructing the insertion of the second support member 320 into the first support member 310, thereby facilitating the installation of the support leg assembly 300.

[0195] This utility model embodiment also proposes an electronic terminal support device, referring to... Figure 1 or Figure 31 It includes a support member 600 and a multi-leg bracket, wherein the support member 600 is mounted on the support rod assembly 100 of the multi-leg bracket.

[0196] For example, the support member 600 is directly or indirectly mounted to the support rod assembly 100, such as a connecting arm 700 mounted to the support rod assembly 100. Specifically, the support member 600 is rotatably mounted to the connecting arm 700, and the support member 600 rotates relative to the connecting arm 700 to adjust the orientation of the electronic terminal (e.g., horizontal, vertical, diagonal, etc.). More specifically, the support member 600 can rotate a full circumference relative to the connecting arm 700. Specifically, the connecting arm 700 is rotatably mounted to the support rod assembly 100, and the connecting arm 700 rotates relative to the support rod assembly 100 to adjust the usage angle of the electronic terminal. When it is necessary to store the electronic terminal bracket, the connecting arm 700 can be folded to the support rod assembly 100, or the connecting arm 700 can be folded to the folded support foot assembly 300.

[0197] For example, the support 600 can be a clamp for holding an electronic terminal. The clamp includes a clamp body 610 and two clamping parts 620. The two clamping parts 620 clamp the opposite two sides of the electronic terminal respectively. The clamp body 610 can be elastically extended and retracted to adjust the clamping width of the clamp. The clamping parts 620 can be housed in the clamp body 610.

[0198] For example, the support 600 is a suction cup for attaching an electronic terminal, such as a suction cup that can be attached to the back of the electronic terminal.

[0199] For example, the support 600 is a magnetic component of a magnetic electronic terminal, and the magnetic component can be an electromagnet or a permanent magnet.

[0200] For example, support 600 is a tray for supporting an electronic terminal, on which the electronic terminal is placed.

[0201] For example, the support 600 is a card holder for a card-holding electronic terminal, and the card holder is used to hold the card-holding electronic terminal.

[0202] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
