Description

Technical Field

[0001] This utility model relates to the field of support equipment technology, and in particular to a support frame that is easy to assemble. Background Technology

[0002] Stands are often designed with a collapsible and unfoldable structure, with multiple support legs that can switch between folded and unfolded states. In the folded state, the support legs allow users to easily hold the support device for shooting, while in the unfolded state, the support legs allow users to place the device on a desk, computer table, shooting platform, or the ground. To further enhance the support strength of the support legs, reinforcing support rods are usually installed between the support legs and the main frame.

[0003] However, in the existing technology, in order to achieve the hinge between the support rod and the support foot, one end of the support rod is usually hinged to the hinge block, and the hinge block is threaded to the support foot. The structure of this hinge is relatively complicated, and the installation of the support rod is time-consuming and labor-intensive in the production process. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a support bracket, which solves the technical problem that the installation of support rods in the production process of existing brackets is time-consuming and labor-intensive.

[0005] According to an embodiment of the present invention, a support bracket includes a main rod, a support foot, a fixing block, a support rod, and a pin. One end of the support foot is rotatably connected to the main rod. The fixing block is disposed on the support foot and cooperates with the support foot to form a rotating hole. One end of the support rod is rotatably connected to the main rod, and the other end is provided with a rotating part, which is disposed in the rotating hole, so that the support rod is rotatably connected to the support foot. Both ends of the pin are respectively inserted into the rotating part, and a torsion spring is sleeved on the pin. The torsion spring includes a first force-applying arm and a second force-applying arm. The second force-applying arm abuts against the support rod, and the first force-applying arm abuts against the support foot, for driving the support foot to rotate.

[0006] According to the bracket of this utility model embodiment, the following beneficial effects can be achieved by the following arrangement: after the pin passes through the torsion spring, both ends are inserted into the rotating part, and the rotating part is rotatably connected to the support leg. With this structure, the pin only needs to pass through the torsion spring and the rotating part, and does not need to be directly connected to the support leg. Compared to the previous method where the pin needed to pass through three structures—the torsion spring, the rotating part, and the support leg—this greatly reduces the assembly difficulty in the production process and improves production efficiency.

[0007] According to some embodiments of the present invention, the torsion spring further includes a spring ring, which is sleeved on the pin, and the first force-applying arm and the second force-applying arm are respectively connected to both ends of the spring ring.

[0009] According to some embodiments of the present invention, at least one of the receiving holes of the left rotating part and the right rotating part is a through hole, and one end of the pin passes through the through hole and is inserted into the other receiving hole.

[0010] According to some embodiments of the present invention, the inner side of the support foot is provided with an inclined abutment surface, and the second force-applying arm abuts against the inclined abutment surface; the fixing block is provided with a pressing groove facing the inclined abutment surface, and the bottom surface of the pressing groove and the inclined abutment surface clamp the second force-applying arm therein.

[0011] According to some embodiments of the present invention, the support rod has a through hole, and the first force-applying arm abuts against the side wall of the through hole.

[0012] According to some embodiments of the present invention, the fixing block has a lateral arc-shaped groove on the side facing the support foot, and the support foot has a corresponding lateral arc-shaped groove on the inner side at a corresponding position, and the two arc-shaped grooves form the rotating hole.

[0013] According to some embodiments of the present invention, the bottom of the fixing block is provided with a rotation notch, and the support rod passes through the rotation notch when it rotates relative to the support foot.

[0014] According to some embodiments of the present invention, the side of the fixing block that is in contact with the supporting foot is provided with a back-facing arc-shaped groove, and the supporting foot is provided with an upward-facing back-facing arc-shaped groove on the inner side at a corresponding position. The two back-facing arc-shaped grooves form the rotating hole.

[0015] According to some embodiments of this utility model, the fixing block and the supporting leg are provided with screw holes, and the fixing block and the supporting leg are connected to the screw holes by screws.

[0037] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0038] The following is for reference. Figures 1 to 14 The bracket according to an embodiment of the present utility model is described below.

[0039] The bracket according to an embodiment of the present invention includes a main rod 700, a support foot 100, a fixing block 200, a support rod 300, and a pin 500. One end of the support foot 100 is rotatably connected to the main rod 700. The fixing block 200 is disposed on the support foot 100 and cooperates with the support foot 100 to form a rotating hole 211. One end of the support rod 300 is rotatably connected to the main rod 700, and the other end is provided with a rotating part 310, which is disposed in the rotating hole 211, so that the support rod 300 is rotatably connected to the support foot 100. Both ends of the pin 500 are respectively inserted into the rotating part 310, and a torsion spring 400 is sleeved on the pin 500. The torsion spring 400 includes a first force-applying arm 420 and a second force-applying arm 430. The second force-applying arm 430 abuts against the support rod 300, and the first force-applying arm 420 abuts against the support foot 100, for driving the support foot 100 to rotate.

[0040] For example Figure 2 , Figure 4 and Figure 6 As shown, the support frame includes a main rod 700, a support leg 100, a fixing block 200, a support rod 300, and a torsion spring 400. One end of the support leg 100 is rotatably connected to the main rod 700, and the other end is a free end. When the support frame is open, the free end of the support leg 100 contacts the ground or other supporting surface, supporting the entire support frame. The fixing block 200 is fastened to the inside of the support leg 100 and forms a rotating hole 211. One end of the support rod 300 is rotatably connected to the main rod 700, and the other end is provided with a rotating part 310. When the rotating part 310 of the support rod 300 is placed in the rotating hole 211, the support rod 300 can only rotate relative to the support leg 100. The first force-applying arm 420 and the second force-applying arm 430 of the torsion spring 400 abut against the support rod 300 and the support leg 100, respectively. When the support leg 100 of the bracket is in the closed state, the first force-applying arm 420 and the second force-applying arm 430 of the torsion spring 400 deform, thereby generating an elastic force. When the support leg 100 of the bracket needs to be opened, the constraint between the support leg 100 and the main rod 700 is released. That is, the elastic force of the torsion spring 400 can spring the support leg 100 and the support rod 300 apart, thereby allowing the support leg 100 to open automatically for easy operation.

[0041] Furthermore, the support rod 300 can be directly and actively connected to the main rod 700, or indirectly connected to the active rotation mechanism, for example... Figure 2 and Figure 3 As shown, the main rod 700 is provided with a sliding sleeve 600, and the support rod 300 is rotatably connected to the sliding sleeve 600.

[0042] According to the bracket of the present invention, by such arrangement, at least the following beneficial effects can be achieved:

[0043] After passing through the torsion spring 400, the pin 500 is inserted into the rotating part 310 at both ends, and the rotating part 310 is rotatably connected to the support leg 100. In this structure, the pin 500 only needs to pass through two structures, the torsion spring 400 and the rotating part 310, and does not need to be directly connected to the support leg 100. Compared with the pin 500, which needs to pass through three structures, the torsion spring 400, the rotating part 310 and the support leg 100, this greatly reduces the assembly difficulty in the production process and improves production efficiency.

[0044] In some specific embodiments of this utility model, the torsion spring 400 further includes a spring ring 410, a first force-applying arm 420 and a second force-applying arm 430 are respectively connected to the spring ring 410, the spring ring 410 is sleeved on the pin 500, and the first force-applying arm 420 and the second force-applying arm 430 are respectively connected to both ends of the spring ring 410.

[0045] For example Figure 6 and Figure 8 As shown, the torsion spring 400 automatically opens the support leg 100 when it is deployed, improving ease of operation. The first force arm 420 and the second force arm 430 of the torsion spring 400 abut against the support rod 300 and the support leg 100, respectively. When the support leg 100 of the bracket is in the closed state, the first force arm 420 and the second force arm 430 of the torsion spring 400 undergo elastic deformation with the spring coil 410, thereby generating an elastic force in the torsion spring 400. When the support leg 100 of the bracket needs to be opened, the constraint between the support leg 100 and the main rod 700 is released, that is, the elastic force of the torsion spring 400 can spring the support leg 100 and the support rod 300 apart, thereby allowing the support leg 100 to open automatically, facilitating personnel operation.

[0046] By fitting the spring coil 410 onto the pin 500 instead of onto the rotating part 310, the spring coil 410 is less likely to shift after being clamped, ensuring the stability of the force direction of the torsion spring 400, and enhancing the stability of the torsion spring 400 installation, thus extending its service life.

[0047] In some specific embodiments of this utility model, the rotating part 310 includes a left rotating part and a right rotating part spaced apart from each other, and both the left rotating part and the right rotating part are provided with receiving holes 311; the two ends of the pin 500 are respectively disposed in the receiving holes 311 of the left rotating part and the right rotating part.

[0048] For example Figure 8 and Figure 10 As shown, the left and right rotating parts are spaced apart, and the two ends of the pin 500 are respectively disposed in the receiving holes 311 of the left and right rotating parts. The pin 500 passes through the receiving holes 311, and the spring ring 410 is sleeved on the pin 500, located between the two rotating parts 310, and sandwiched in the middle by the two rotating parts 310, so that the position of the spring ring 410 is relatively fixed.

[0049] In some specific embodiments of this utility model, at least one receiving hole 311 of the left rotating part and the right rotating part is a through hole, and one end of the pin 500 passes through the through hole and is inserted into another receiving hole 311.

[0050] For example Figure 10 As shown, both receiving holes 311 of the left rotating part and the right rotating part are through holes. After one end of the pin 500 passes through the through hole, it is inserted into the other receiving hole 311 for fixation. This installation method can facilitate the installation of the pin.

[0051] In some specific embodiments of this utility model, an inclined abutment surface 110 is provided on the inner side of the support foot 100, and the second force-applying arm 430 abuts against the inclined abutment surface 110. A pressing groove 220 is provided on the fixing block 200 facing the inclined abutment surface 110, and the bottom surface of the pressing groove 220 and the inclined abutment surface 110 clamp the second force-applying arm 430 therein.

[0052] For example Figure 7 , Figure 8 and Figure 11 As shown, the inner side of the support leg 100 is provided with an inclined abutment surface 110, and the second force arm 430 of the torsion spring 400 is attached to the inclined abutment surface 110. The inclined abutment surface 110 increases the contact area between the second force arm 430 of the torsion spring 400 and the support leg 100, disperses stress concentration, prevents the second force arm 430 from deforming due to excessive local stress, and improves structural durability.

[0053] The fixing block 200 has a pressing groove 220 on its inner side facing the support foot 100. The pressing groove 220 is positioned relative to the inclined abutment surface 110, and the bottom surface of the pressing groove 220 and the inclined abutment surface 110 clamp the second force-applying arm 430 therein. The pressing groove 220 restricts the range of motion of the second force-applying arm 430, preventing it from shifting during operation and ensuring the stability of the force applied by the torsion spring 400.

[0054] In some specific embodiments of this utility model, a through hole 320 is provided on the support rod 300, and the first force-applying arm 420 passes through the through hole 320 and abuts against the outer side of the support rod 300 facing away from the support foot 100.

[0055] For example Figure 3 , Figure 5 and Figure 7 As shown, a through hole 320 is provided on the support rod 300. The first force-applying arm 420 passes through the through hole 320 and abuts against the outer side of the support foot 100. The through hole 320 guides the direction of the force applied by the first force-applying arm 420, so that it acts directly on the outside of the support rod 300, thereby improving the driving efficiency of the torsion spring 400 on the support rod 300.

[0056] In some specific embodiments of this utility model, the fixing block 200 and the support foot 100 are provided with screw holes 240, and the fixing block 200 and the support foot 100 are connected by screws and screw holes 240.

[0057] In some specific embodiments of this utility model, the fixing block 200 has a lateral arc groove 210 on the side facing the support foot 100, and the support foot 100 has a corresponding lateral arc groove 210 on the inner side at the corresponding position. The two lateral arc grooves 210 surround the rotating hole 211.

[0058] For example Figures 8 to 11 As shown, the fixing block 200 has a lateral arc-shaped groove 210 on the side facing the support foot 100, and the support foot 100 also has a corresponding lateral arc-shaped groove 210 at the corresponding position on the inner side. The two lateral arc-shaped grooves 210 form a rotating hole 211, which confines the rotating part 310 of the support rod 300 within it, so that the rotating part 310 can only rotate within the rotating hole 211, thereby allowing the support rod 300 to rotate relative to the support foot 100. The support rod 300 connects the main rod 700 and the support foot 100 at the same time, so that the support foot 100 can support the main rod 700 more stably.

[0059] The circular rotating hole 211 formed by the double-sided arc groove 210 structure makes the rotating part 310 evenly stressed, improves the stability and durability of the rotation of the support rod 300, reduces the friction between the rotating part 310 and the hole wall, makes the rotation of the support rod 300 smoother, and extends its service life.

[0060] In some specific embodiments of this utility model, the bottom of the fixing block 200 is provided with a rotation notch 230, and the support rod 300 passes through the rotation notch 230 when it rotates relative to the support foot 100.

[0061] For example Figure 11 As shown, the bottom of the fixing block 200 has a rotation notch 230, through which the support rod 300 passes when it rotates. The rotation notch 230 provides rotation space for the support rod 300, avoids interference with the fixing block 200, and ensures that the support rod 300 can be fully extended.

[0062] In some specific embodiments of this utility model, the side of the fixing block 200 that is in contact with the support foot 100 is provided with a back arc groove 212, and the support foot 100 is provided with a back arc groove 212 with the opening facing upward on the inner side. The two back arc grooves 212 form a rotating hole 211.

[0063] For example Figure 12 , Figure 13 and Figure 14As shown, the bottom of the fixing block 200 has a back-facing arc-shaped groove 212, and the support foot 100 has an upward-opening back-facing arc-shaped groove 212 at a corresponding position on its inner side. The two back-facing arc-shaped grooves 212 form a rotating hole 211. The two back-facing arc-shaped grooves 212 form a rotating hole 211, which confines the rotating part 310 of the support rod 300 within it, so that the rotating part 310 can only rotate within the rotating hole 211. This allows the support rod 300 to rotate relative to the support foot 100. The support rod 300 connects the main rod 700 and the support foot 100, thereby enabling the support foot 100 to support the main rod 700 more stably.

[0064] The circular rotating hole 211 formed by the double-backed arc groove 212 structure makes the rotating part 310 evenly stressed, improves the stability and durability of the rotation of the support rod 300, reduces the friction between the rotating part 310 and the hole wall, makes the rotation of the support rod 300 smoother, and extends its service life.

[0065] For example Figure 6 and Figure 8 As shown, the fixing block 200 and the support foot 100 are provided with screw holes 240, and the fixing block 200 and the support foot 100 are connected by screws and screw holes 240. The connection structure of screws and screw holes 240 ensures reliable fixing of the fixing block 200 and the support foot 100, and at the same time facilitates disassembly and replacement during later maintenance.

[0066] In some specific embodiments of this utility model, the fixing block 200 and the support foot 100 are provided with an arc-shaped surface facing the main rod. The curvature of the arc-shaped surface is adapted to the main rod. When the support foot 100 is in the closed state, the arc-shaped surface is in contact with the outer wall of the main rod.

[0067] For example Figure 5 and Figure 6 As shown, the fixing block 200 and the support foot 100 are provided with an arc-shaped surface facing the main rod. The curvature of the arc-shaped surface is adapted to the main rod. When the support foot 100 is in the closed state, the arc-shaped surface is in contact with the outer wall of the main rod.
