Mounting structure, battery and power device

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on February 26, 2024, with application number 202420346857.8 and invention name “Mounting structure, battery and electrical device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application belongs to the field of battery technology, and more specifically, relates to a mounting structure, a battery, and an electrical device. Background Art

[0003] The statements here only provide background information related to the present application and do not necessarily constitute prior art. For rapid battery replacement of electric vehicles, a mounting lock is provided on the battery. One type of mounting lock uses a mounting screw with a mounting cap on the top to achieve rapid connection with the vehicle frame. This structure requires that the lower end of the mounting screw be made relatively thin so that the lock sleeve of the mounting lock can be inserted from the top and connected to the internal thread section of the tightening screw so that the mounting screw can be pulled by tightening the screw and the mounting screw can be driven to rotate. However, since the tightening screw needs to frequently rotate relative to the lower end of the mounting screw, the strength of the joint between the lower end of the mounting screw and the tightening screw is low, which affects the service life of the mounting lock.

[0004] Application Contents

[0005] The purpose of the embodiments of the present application is to provide a mounting structure, a battery, and an electrical device to solve the problem of low structural strength of the lower end of the mounting screw of the mounting lock in the related art.

[0006] In a first aspect, an embodiment of the present application provides a mounting structure, including:

[0007] The lock sleeve is provided with a cavity, and the cavity passes through the opposite ends of the lock sleeve along the axial direction of the lock sleeve;

[0008] A mounting screw having a first end and a second end opposite to each other, the second end being disposed in the cavity and the first end extending out of the locking sleeve;

[0009] A tightening screw is placed in the locking sleeve, the tightening screw has an internal thread section, and the internal thread section is threadedly connected to the second end;

[0010] The mounting cap is provided with a connecting hole adapted to connect to the first end of the mounting screw.

[0011] In the technical solution of the embodiment of the present application, a mounting screw and a mounting cap are provided, and a connecting hole is provided on the mounting cap to be connected to the first end of the mounting screw. During assembly, the first end of the mounting screw can be inserted from one end of the locking sleeve and then extended from the other end. In this way, the diameter of the second end of the mounting screw can be set relatively large to improve the structural strength of the second end of the mounting screw, thereby improving the strength of the fitting between the second end of the mounting screw and the tightening screw.

[0012] In some embodiments, the mounting structure further includes a locking member for locking the mounting cap to the first end, and the first end is provided with an adapting structure for cooperating with the locking member to lock the mounting cap.

[0013] A locking member and an adapting structure are provided to lock the mounting cap on the first end of the mounting screw, so that the mounting cap and the mounting screw are firmly connected and the risk of the mounting cap moving axially along the mounting screw is reduced.

[0014] In some embodiments, the first end includes an external thread segment, the connecting hole is provided with an internal thread threadedly connected to the external thread segment, the locking member includes a locking block connected to the mounting cap, the locking block is provided with an opening for inserting the first end, the adaptation structure includes a stop portion provided on the side of the first end, the inner surface of the opening is provided with a matching portion, and the stop portion and the matching portion are adapted to limit the rotation of the locking block around the mounting screw.

[0015] An external thread section and an internal thread are provided to enable the mounting cap to be threadedly installed on the first end of the mounting screw for easy connection; a mating portion is provided in the opening of the locking block, and a stop portion is provided on the side of the first end. The stop portion cooperates with the mating portion to limit the locking block from rotating around the mounting screw, and the locking block is connected to the mounting cap, so that the mounting cap can be limited from rotating on the external thread section, thereby reducing the risk of the mounting cap loosening to a certain extent.

[0016] In some embodiments, the stop portion includes a first plane, and the matching portion includes a second plane that fits and mates with the stop portion;

[0017] And / or, the stop portion includes a first curved surface, the first curved surface is eccentrically arranged relative to the axial direction of the mounting screw, and the matching portion includes a second curved surface adapted to fit with the stop portion;

[0018] And / or, the stopping portion includes a protrusion, the matching portion includes a slot for the protrusion to be inserted into, and the slot is extended along the axial direction of the mounting screw;

[0019] And / or, the stopping portion includes a slot extending along the axial direction of the mounting screw, and the matching portion includes a protrusion adapted to be inserted into the slot.

[0020] Both the stop portion and the mating portion use flat surfaces. When the two flat surfaces are in contact with each other, they can limit the rotation of the locking block around the mounting screw, and then limit the rotation of the mounting cap on the external thread section, thereby reducing the risk of the mounting cap loosening to a certain extent.

[0021] An eccentric first curved surface is provided on the mounting screw, and a second curved surface is provided on the mating portion to cooperate with the first curved surface of the stop portion, which can also limit the rotation of the locking block around the mounting screw, and then limit the rotation of the mounting cap on the external thread section, thereby reducing the risk of the mounting cap loosening to a certain extent.

[0022] The stop part adopts a protrusion and the mating part adopts a slot. The protrusion and the slot are mated and plugged together to limit the rotation of the locking block around the mounting screw, thereby limiting the rotation of the mounting cap in the external thread section, thereby reducing the risk of the mounting cap loosening to a certain extent.

[0023] The stop part adopts a slot and the mating part adopts a protrusion. The protrusion is plugged into the slot to limit the rotation of the locking block around the mounting screw, and then limit the rotation of the mounting cap in the external thread section, thereby reducing the risk of loosening of the mounting cap to a certain extent.

[0024] In some embodiments, the stop portion is provided at an end of the external thread segment away from the second end, and the radius of the external thread segment is greater than or equal to the maximum distance from the side surface of the stop portion to the central axis of the mounting screw.

[0025] The stop part is arranged at the end of the external thread segment away from the second end to facilitate the processing and production of the blocking part; since the internal thread of the connecting hole of the mounting cap is adapted to be connected with the external thread segment, the inner diameter of the connecting hole is equal to or similar to the radius of the external thread segment, and the radius of the external thread segment is set to be greater than or equal to the maximum distance from the side of the stop part to the central axis of the mounting screw, the stop part can pass through the connecting hole so that the internal thread is connected to the external thread segment, and then the mounting cap is installed on the mounting screw.

[0026] In some embodiments, the stop portion is provided at one end of the external thread segment close to the second end, and the radius of the external thread segment is less than or equal to the minimum distance from the side surface of the stop portion to the central axis of the mounting screw.

[0027] The stop portion is provided at one end of the external thread section close to the second end, so that the locking block can be in contact with the carrying medium when mounted and used, thereby protecting the mounting cap; since the locking block is located at a position corresponding to the stop portion, the opening on the locking block needs to be adapted to fit the position of the mounting screw corresponding to the stop portion, and the radius of the external thread section is set to be less than or equal to the minimum distance from the side surface of the stop portion to the central axis of the mounting screw, so that the external thread section can pass through the opening conveniently, so that the opening reaches the stop portion, so that the locking block can be installed on the mounting screw, and the matching portion is connected to the stop portion.

[0028] In some embodiments, the opening is interference-fitted with a region of the mounting screw corresponding to the stop portion; and / or, an inner surface of the opening is bonded to a region of the mounting screw corresponding to the stop portion.

[0029] The inner surface of the opening is interference fit or bonded with the area of ​​the mounting screw corresponding to the stop portion to fix the locking block on the mounting screw. This can, to a certain extent, prevent the locking block from loosening, and further prevent the mounting cap from loosening.

[0030] In some embodiments, a groove is provided on one of the locking block and the mounting cap, and an inserting protrusion that fits into the groove is provided on the other of the locking block and the mounting cap.

[0031] The connection between the locking block and the mounting cap is achieved by plugging and fitting the groove and the plug-in protrusion. The rotation of the mounting cap must drive the locking block to rotate, and then the limited locking block rotates on the mounting screw, which can limit the rotation of the mounting cap on the mounting screw, thereby preventing the mounting cap from loosening.

[0032] In some embodiments, the mounting structure further includes a snap ring disposed on the mounting screw, and the snap ring is used to limit the locking block from moving in a direction away from the mounting cap.

[0033] A retaining ring is set up, and the axial position of the locking block along the mounting screw can be limited by cooperating with the mounting cap and the retaining ring, so as to position and fix the locking block, so that the locking block can better lock the mounting screw and prevent the mounting cap from loosening.

[0034] In some embodiments, a ring groove is provided on the mounting screw, and the retaining ring is clamped in the ring groove.

[0035] A ring groove is provided on the mounting screw to facilitate positioning and installation of the snap ring.

[0036] In some embodiments, a flared section is provided at one end of the opening away from the mounting cap, and when the locking block abuts against the snap ring, the snap ring is accommodated in the flared section.

[0037] A flared section is provided in the opening to accommodate the snap ring, thereby protecting the snap ring.

[0038] In some embodiments, a first mounting hole is opened on the side of the mounting cap, the adapting structure includes a second mounting hole on the side of the first end, and the locking member includes a connecting member that is fitted into the first mounting hole and the second mounting hole.

[0039] A connecting piece is provided and installed in the first mounting hole and the second mounting hole to fix the mounting cap on the mounting screw. This can limit the axial movement of the mounting cap along the mounting screw and limit the rotation of the mounting cap on the mounting screw. The structure is simple and easy to fix.

[0040] In some embodiments, the locking sleeve is provided with a slideway for guiding the mounting screw to rotate to a set angle, and the mounting screw is provided with a guide pin, which extends into the slideway.

[0041] When the mounting screw is tightened to pull the mounting screw to move axially along the locking sleeve, the mounting screw can be guided to rotate to a set angle through the cooperation of the slideway and the guide pin, thereby driving the mounting cap to rotate to a set angle; when in use, the mounting screw is pulled toward the second end to rotate the mounting cap to a set angle so that the mounting cap is mounted on the carrier medium; conversely, the mounting screw is pushed toward the first end to reverse the mounting cap to a set angle, thereby separating the mounting cap from the carrier medium, thereby achieving rapid mounting and separation.

[0042] In some embodiments, the mounting structure also includes an anti-rotation mechanism, which includes a sliding sleeve that limits the rotation of the tightening screw and a stopper that cooperates to limit the rotation of the sliding sleeve. The stopper is fixedly connected to the locking sleeve, and the sliding sleeve is slidably mounted on the tightening screw along the axial direction of the tightening screw.

[0043] By fixing the stopper on the locking sleeve, fitting the sliding sleeve on the tightening screw, and connecting the sliding sleeve to the stopper, the stopper can limit the rotation of the sliding sleeve, thereby limiting the rotation of the tightening screw, and the tightening screw is threadedly connected to the second end of the mounting screw, thereby limiting the rotation of the mounting screw and achieving the anti-rotation effect; and using a tool to push the sliding sleeve to slide on the tightening screw to separate the sliding sleeve from the stopper, the tightening screw can be rotated to promote the rotation and axial movement of the mounting screw.

[0044] In some embodiments, an elastic member is installed in the locking sleeve to elastically push the sliding sleeve toward the stop member.

[0045] An elastic member is provided. After the tool that pushes the sliding sleeve away from the stop member is removed, the elastic member can push the sliding sleeve to contact the stop member to limit the rotation of the sliding sleeve, thereby limiting the rotation of the tightening screw and achieving the anti-rotation effect.

When an element is referred to as being “connected to” another element, it may be directly connected to the other element or indirectly connected to the other element.

[0074] In the embodiments of the present application, battery cells include, but are not limited to, lithium-ion secondary batteries, lithium-ion primary batteries, lithium-sulfur batteries, sodium-lithium-ion batteries, sodium-ion batteries, or magnesium-ion batteries. The shapes of battery cells include, but are not limited to, cylindrical, flat, rectangular, or other shapes. Battery cells are generally categorized by packaging method, including, but not limited to, cylindrical, prismatic, and pouch-type battery cells.

[0075] The battery mentioned in the embodiments of this application refers to a single physical module that includes one or more battery cells to provide higher voltage and capacity. For example, the battery mentioned in this application may include a battery module or a battery pack. The battery generally includes a casing for encapsulating one or more battery cells. The casing can, to a certain extent, prevent liquids or other foreign matter from affecting the charging or discharging of the battery cells. In some cases, the battery cells can also be used directly, that is, the battery may not include a casing, which is not limited here.

[0076] In a battery, when there are multiple battery cells, they can be connected in series, in parallel, or in a hybrid connection. A hybrid connection refers to a combination of series and parallel connections. Multiple battery cells can be directly connected in series, in parallel, or in a hybrid connection, and then the entire battery cell structure is housed within a housing. Alternatively, a battery can be constructed by first connecting multiple battery cells in series, in parallel, or in a hybrid connection to form a battery module, which is then connected in series, in parallel, or in a hybrid connection to form a single unit, which is then housed within a housing. The battery may also include other structures, such as a busbar assembly for electrically connecting multiple battery cells.

[0077] The charging speed of electric vehicles has always been a concern for people. Rapid battery swapping for electric vehicles can address the concern about the long charging time. A good way to achieve rapid battery swapping in electric vehicles is to install a mounting lock on the battery. This lock allows the battery to be mounted and locked to the vehicle frame, allowing for quick installation. To remove the battery, simply unlock it and remove it from the vehicle.

[0078] One type of mounting lock uses a mounting screw with a mounting cap on the top. By mounting the mounting cap on the vehicle frame, it can be quickly mounted to the vehicle frame. This structure requires the lower end of the mounting screw to be made relatively thin so that it can be inserted into the locking sleeve of the mounting lock from the top and connected to the internal threaded section of the tightening screw. This allows the mounting screw to be pulled axially along the locking sleeve by tightening the screw, and drives the mounting screw and the mounting cap on it to rotate, thereby achieving the mounting cap and the vehicle frame. However, because the tightening screw needs to frequently rotate relative to the lower end of the mounting screw, the strength of the joint between the lower end of the mounting screw and the tightening screw is relatively low, which affects the service life of the mounting lock.

[0079] Based on the above considerations, in order to solve the problem of low structural strength of the lower end of the mounting screw of the mounting lock, an embodiment of the present application provides a mounting structure, by setting a connecting hole on the mounting cap to be connected to the first end of the mounting screw. During production, the mounting cap and the mounting screw can be made separately; and during assembly, the first end of the mounting screw can be inserted from one end of the lock sleeve and then extended from the other end. In this way, the diameter of the second end of the mounting screw can be set relatively large to improve the structural strength of the second end of the mounting screw, thereby improving the strength of the fitting between the second end of the mounting screw and the tightening screw.

[0080] The battery disclosed in the embodiments of the present application can be applied not only to electric vehicles, but also to other electrical devices that use batteries as power sources or various energy storage systems that use batteries as energy storage elements, such as energy storage power supply systems for hydropower, thermal power, wind power, and solar power stations. The electrical devices can be, but are not limited to, mobile phones, tablets, laptops, electric toys, electric tools, electric bicycles, electric motorcycles, electric cars, ships, spacecraft, and the like. Among them, electric toys can include fixed or mobile electric toys, such as game consoles, electric car toys, electric ship toys, and electric airplane toys, and the like, and spacecraft can include airplanes, rockets, space shuttles, and spacecraft, and the like.

[0081] For the convenience of description, an electric device is provided in accordance with an embodiment of the present application, and the electric device is described by taking a vehicle as an example.

[0082] Please refer to Figure 1, which is a schematic structural diagram of a vehicle 1000 provided in some embodiments of the present application. The vehicle 1000 can be a fuel vehicle, a gas vehicle or a new energy vehicle. The new energy vehicle can be a pure electric vehicle, a hybrid vehicle or an extended-range vehicle, etc. A battery 1001 is provided inside the vehicle 1000, and the battery 1001 can be provided at the bottom, head or tail of the vehicle 1000. The battery 1001 can be used to power the vehicle 1000. For example, the battery 1001 can serve as an operating power source for the vehicle 1000. The vehicle 1000 may also include a controller 1002 and a motor 1003. The controller 1002 is used to control the battery 1001 to power the motor 1003, for example, for starting, navigating and driving the vehicle 1000.

[0083] In some embodiments of the present application, the battery 1001 can serve not only as an operating power source for the vehicle 1000, but also as a driving power source for the vehicle 1000, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1000.

[0084] Please refer to Figure 2, which is a schematic diagram of the exploded structure of a battery 1001 provided in some embodiments of the present application. Battery 1001 includes a housing 100 and a battery cell 200, with the battery cell 200 housed within the housing 100. The housing 100 is used to provide a storage space for the battery cell 200, and the housing 100 can adopt a variety of structures. In some embodiments, the housing 100 can include a first portion 101 and a second portion 102, which cover each other and together define a storage space for accommodating the battery cell 200. The second portion 102 can be a hollow structure with one end open, and the first portion 101 can be a plate-like structure, with the first portion 101 covering the open side of the second portion 102, so that the first portion 101 and the second portion 102 jointly define a storage space. The first portion 101 and the second portion 102 can also be hollow structures with one end open, with the open side of the first portion 101 covering the open side of the second portion 102. Of course, the box 100 formed by the first part 101 and the second part 102 can be of various shapes, such as a cylinder, a cuboid, etc. After the multiple battery cells 200 are connected in parallel, in series, or in a mixed combination, they are placed in the box 100 formed by the first part 101 and the second part 102 being fastened together.

[0085] In some embodiments, a mounting structure 300 may be installed on the box 100 to enable the battery 1001 to be quickly mounted on an electrical device such as a vehicle frame, and of course, to facilitate replacement of the battery 1001 .

[0086] Referring to Figures 3 to 7 , according to some embodiments of the present application, a mounting structure 300 is provided, comprising a locking sleeve 35, a mounting screw 31, a tightening screw 36, and a mounting cap 32. The locking sleeve 35 defines a cavity 350, which extends axially through the locking sleeve 35 at opposite ends. The mounting screw 31 has opposing first and second ends 311 and 312, with the second end 312 of the mounting screw 31 positioned within the cavity 350 and the first end 311 of the mounting screw 31 extending out of the locking sleeve 35. The tightening screw 36 is positioned within the locking sleeve 35 and has an internally threaded section 361, which is threadably connected to the second end 312 of the mounting screw 31. The mounting cap 32 defines a connecting hole 321 adapted to connect to the first end 311 of the mounting screw 31.

[0087] The locking sleeve 35 refers to the shell structure of the mounting structure 300. When in use, the locking sleeve 35 is connected to the supporting medium 80, such as being supported on the box 100 of the battery 1001, to fix the mounting structure 300 to the supporting medium 80. The locking sleeve 35 cooperates with the mounting cap 32 to clamp the supporting medium 90, such as the vehicle frame, to fix the mounting structure 300 to the supporting medium 90, thereby connecting the supporting medium 80 to the supporting medium 90. Of course, the locking sleeve 35 and the mounting cap 32 can also cooperate to clamp the supporting medium 80 and the supporting medium 90 to connect the supporting medium 80 to the supporting medium 90. The cavity 350 refers to the accommodating space provided in the locking sleeve 35, and along the axial direction of the locking sleeve 35, the cavity 350 passes through the opposite ends of the locking sleeve 35, so that the cavity 350 forms a hole-like structure that passes through the locking sleeve 35, so as to facilitate the processing and manufacturing of the locking sleeve 35. The outer contour of the locking sleeve 35 can be set to a block shape, a column shape, etc. The lock sleeve 35 can be made of materials such as steel, manganese, and aluminum alloy.

[0088] The mounting screw 31 is a rod-shaped structure with an external thread at its second end 312. The first end 311 and the second end 312 are opposite ends of the mounting screw 31. After assembly, the first end 311 of the mounting screw 31 is located outside the locking sleeve 35, while the second end 312 of the mounting screw 31 is located inside the locking sleeve 35.

[0089] The tightening screw 36 is a rod-shaped structural member that can be turned by a tool. It is placed in the locking sleeve 35, specifically within the cavity 350 of the locking sleeve 35, where it is protected by the locking sleeve 35. The internally threaded section 361 is a section of the tightening screw 36 with internal threads. The internally threaded section 361 is threadedly connected to the second end 312 of the mounting screw 31, enabling the mounting screw 31 to move axially when the tightening screw 36 is rotated.

[0090] Referring to Figures 8 and 9 , the mounting cap 32 is a structural member used to mount on the carrier medium 90. The connecting hole 321 is a hole structure provided on the mounting cap 32. The connecting hole 321 is adapted to mate with the first end 311 of the mounting screw 31. The first end 311 of the mounting screw 31 can be adapted to connect with the connecting hole 321, thereby attaching the mounting cap 32 to the first end 311 of the mounting screw 31. The length and width of the mounting cap 32 are both perpendicular to its height. When the mounting cap 32 is mounted on the mounting screw 31, its height aligns with the axial direction of the mounting screw 31. Furthermore, in a cross-section perpendicular to its height, the longer side of the mounting cap 32 corresponds to its length, while the shorter side corresponds to its width. The length of the mounting cap 32 is generally greater than its width, resulting in a rectangular structure along a cross-section perpendicular to its height. In one application example, the rectangular hole 91 provided on the carrier medium 90 is configured such that the length of the rectangular hole 91 is greater than the length of the mounting cap 32, the width of the rectangular hole 91 is greater than the width of the mounting cap 32, and the width of the rectangular hole 91 is configured such that the length of the mounting cap 32 is less than the length of the mounting cap 32. During mounting assembly, the mounting cap 32 can be aligned with the length of the rectangular hole 91, and then the mounting cap 32 can be passed through the rectangular hole 91. The mounting cap 32 can then be rotated and the mounting screw 31 pulled so that the two ends of the mounting cap 32 can be supported on opposite sides of the rectangular hole 91, thereby achieving mounting assembly. Conversely, by loosening the mounting screw 31 so that the mounting cap 32 can be rotated until its length is aligned with the length of the rectangular hole 91, the mounting cap 32 and the mounting screw 31 can then be removed from the rectangular hole 91 of the carrier medium 90 for quick disassembly.

[0091] A connecting hole 321 is provided on the mounting cap 32 for connecting with the first end 311 of the mounting screw 31. This allows the mounting cap 32 and the mounting screw 31 to be manufactured separately and then assembled. Since the mounting screw 31 and the mounting cap 32 are manufactured separately, when the mounting structure 300 is assembled, the first end 311 of the mounting screw 31 can be inserted into the cavity 350 from one end of the locking sleeve 35 and then extended from the other end of the locking sleeve 35, with the second end 312 of the mounting screw 31 positioned within the locking sleeve 35. Since the second end 312 of the mounting screw 31 does not need to pass through the locking sleeve 35, the diameter of the second end 312 of the mounting screw 31 can be set relatively large to enhance the structural strength of the second end 312 and facilitate connection and tightening with the internal thread section 361 of the tightening screw 36.

[0092] In the technical solution of the embodiment of the present application, a mounting screw 31 and a mounting cap 32 are provided, and a connecting hole 321 is provided on the mounting cap 32 to be connected to the first end 311 of the mounting screw 31. During assembly, the first end 311 of the mounting screw 31 can be inserted from one end of the locking sleeve 35 and then extended from the other end. In this way, the diameter of the second end 312 of the mounting screw 31 can be set to be relatively large to improve the structural strength of the second end 312 of the mounting screw 31, thereby improving the strength of the fitting between the second end 312 of the mounting screw 31 and the tightening screw 36.

[0093] Referring to Figures 6 and 10 to 14, in some embodiments, the mounting structure 300 further includes a locking member 33 for locking the mounting cap 32 to the first end 311, and the first end 311 is provided with an adapting structure 314 that cooperates with the locking member 33 to lock the mounting cap 32.

[0094] Locking refers to locking two structural parts together to prevent them from moving relative to each other. Locking two structural parts can be unlocked using a specific tool to separate them, making them easier to manufacture, repair, and replace.

[0095] The locking member 33 is a structural member for locking the mounting cap 32 to the first end 311 of the mounting screw 31 .

[0096] The adapting structure 314 refers to a structural component provided at the first end 311 of the mounting screw 31 and locked with the locking component 33 .

[0097] A locking member 33 and an adapting structure 314 are provided to lock the mounting cap 32 to the first end 311 of the mounting screw 31, thereby firmly connecting the mounting cap 32 to the mounting screw 31 and reducing the risk of the mounting cap 32 moving axially along the mounting screw 31. Of course, since the mounting cap 32 is mounted on the carrier medium 90, it may rub against the carrier medium 90. For example, if the carrier medium 90 vibrates, the mounting cap 32 may rub against the carrier medium 90 when being removed from the carrier medium 90, causing damage to the mounting cap 32. After the mounting cap 32 is locked to the first end 311 of the mounting screw 31, the locking member 33 can be unlocked using a tool, allowing the mounting cap 32 to be separated from the first end 311 of the mounting screw 31 for easy maintenance or replacement.

[0098] In some embodiments, the first end 311 includes an external thread segment 313, the connecting hole 321 is provided with an internal thread 3211 threadedly connected to the external thread segment 313, the locking member 33 includes a locking block 331 connected to the mounting cap 32, and the locking block 331 is provided with an opening 3311 for inserting the first end 311. The adaptation structure 314 includes a stop portion 3141 provided on the side of the first end 311, and the inner surface of the opening 3311 is provided with a matching portion 3312. The stop portion 3141 is adapted to the matching portion 3312 to limit the rotation of the locking block 331 around the mounting screw 31.

[0099] The external thread section 313 is a section of the first end 311 of the mounting screw 31 having an external thread. An internal thread 3211 is provided in the connecting hole 321 to be threadedly connected to the external thread section 313, thereby allowing the mounting cap 32 to be installed on the first end 311 of the mounting screw 31.

[0100] The locking block 331 is a structural component used to limit the rotation of the mounting cap 32. The locking block 331 is provided with an opening 3311 to fit over the first end 311 of the mounting screw 31, thereby securing the locking block 331 to the first end 311 of the mounting screw 31. A mating portion 3312 is provided on the inner surface of the opening 3311, while the adapting structure 314 utilizes a stop portion 3141. When the locking block 331 is positioned over the first end 311 of the mounting screw 31 and reaches the corresponding position of the stop portion 3141, the stop portion 3141 mates with the mating portion 3312, restricting the locking block 331 from rotating about the mounting screw 31. Since the locking block 331 is connected to the mounting cap 32, when the locking block 331 cannot rotate on the mounting screw 31, the mounting cap 32 can be limited to rotate on the mounting screw 31. The mounting cap 32 is threadedly connected to the mounting screw 31, and the mounting cap 32 cannot rotate on the mounting screw 31, that is, the mounting cap 32 can be fixed, thereby achieving the anti-loosening effect of the mounting cap 32.

[0101] An external thread section 313 and an internal thread 3211 are provided to enable the mounting cap 32 to be threadedly installed on the first end 311 of the mounting screw 31 for easy connection; and a matching portion 3312 is provided in the opening 3311 of the locking block 331, and a stop portion 3141 is provided on the side of the first end 311. The stop portion 3141 cooperates with the matching portion 3312 to limit the locking block 331 from rotating around the mounting screw 31, and the locking block 331 is connected to the mounting cap 32, so that the mounting cap 32 can be limited to rotate on the external thread section 313, thereby reducing the risk of the mounting cap 32 loosening to a certain extent.

[0102] Referring to FIG. 4 to FIG. 7 , in some embodiments, the stopping portion 3141 includes a first plane 31411 , and the matching portion 3312 includes a second plane 33121 adapted to fit with the stopping portion 3141 .

[0103] Since the outer profile of the mounting screw 31 is cylindrical, the stop portion 3141 is set as the first plane 31411, and the matching portion 3312 is set as the second plane 33121, that is, the part inside the opening 3311 of the locking block 331 corresponding to the stop portion 3141 is set to be a plane. When the locking block 331 is installed on the mounting screw 31, the two planes are abutted against each other, which can limit the rotation of the locking block 331 on the mounting screw 31, and then limit the rotation of the mounting cap 32 on the mounting screw 31, thereby realizing the anti-loosening effect of the mounting cap 32.

[0104] Both the stop portion 3141 and the mating portion 3312 use flat surfaces. When the two planes are in contact with each other, they can limit the rotation of the locking block 331 around the mounting screw 31, and then limit the rotation of the mounting cap 32 on the external thread section 313, thereby reducing the risk of the mounting cap 32 loosening to a certain extent.

[0105] In some embodiments, one or more planar stoppers 3141 may be provided around the mounting screw 31. The number of planar mating portions 3312 provided on the inner wall of the opening 3311 of the corresponding locking block 331 corresponds one-to-one to the number of stoppers 3141. For example, if the cross-section of a section of the mounting screw 31 corresponding to the stopper 3141 is polygonal, such as triangular, rectangular, or hexagonal, the opening 3311 may be provided in a corresponding polygonal shape.

[0106] Please refer to FIG. 11 . In some embodiments, the stop portion 3141 includes a first curved surface 31414 , which is eccentrically disposed relative to the axis of the mounting screw 31 . The fitting portion 3312 includes a second curved surface 33124 adapted to fit the stop portion 3141 .

[0107] The first curved surface 31414 is eccentrically disposed relative to the axial direction of the mounting screw 31, meaning that the central axis of the first curved surface 31414 is spaced from the central axis of the mounting screw 31, or the central axis of a portion of the first curved surface 31414 is spaced from the central axis of the mounting screw 31. This results in a non-circular cross-section of the mounting screw 31 at the stop portion 3141, and the mating portion 3312 mates with the stop portion 3141, with the corresponding opening 3311 also being a non-circular hole. This allows the locking block 331 to be mounted on the mounting screw 31, restricting its rotation on the mounting screw 31 and, in turn, restricting the mounting cap 32 from rotating on the mounting screw 31, thereby preventing the mounting cap 32 from loosening.

[0108] An eccentric first curved surface 31414 is provided on the mounting screw 31, and a second curved surface 33124 is provided on the mating portion 3312 to cooperate with the first curved surface 31414 of the stop portion 3141, which can also limit the rotation of the locking block 331 around the mounting screw 31, thereby limiting the rotation of the mounting cap 32 on the external thread section 313, thereby reducing the risk of loosening of the mounting cap 32 to a certain extent.

[0109] Referring to FIG. 10 , in some embodiments, the stop portion 3141 includes a protrusion 31413 , and the matching portion 3312 includes a slot 33123 for the protrusion 31413 to be inserted into. The slot 33123 is extended along the axial direction of the mounting screw 31 .

[0110] The protrusion 31413 is a protruding structure provided on the side of the mounting screw 31. The protrusion 31413 can be provided in a strip, column, or dot shape. The protrusion 31413 and the mounting screw 31 can be integrally formed, or they can be manufactured separately and then welded to the mounting screw 31.

[0111] The slot 33123 refers to a groove structure provided on the inner surface of the opening 3311 of the locking block 331 .

[0112] When the locking block 331 is installed on the mounting screw 31 , the protrusion 31413 is inserted into the slot 33123 to limit the rotation of the locking block 331 on the mounting screw 31 , thereby limiting the rotation of the mounting cap 32 on the external thread section 313 .

[0113] The stop portion 3141 adopts a protrusion 31413, and the matching portion 3312 adopts a slot 33123. The protrusion 31413 is matched and plugged into the slot 33123 to limit the rotation of the locking block 331 around the mounting screw 31, thereby limiting the rotation of the mounting cap 32 on the external thread section 313, thereby reducing the risk of loosening of the mounting cap 32 to a certain extent.

[0114] Please refer to FIG. 10 . In some embodiments, the stopping portion 3141 includes a slot 31412 extending axially along the mounting screw 31 , and the matching portion 3312 includes a protrusion 33122 adapted to be inserted into the slot 31412 .

[0115] The slot 31412 refers to a slot structure provided on the side surface of the mounting screw 31 .

[0116] Bump 33122 is a protruding structure provided on the inner surface of opening 3311 of locking block 331. Bump 33122 can be provided in a strip, column, or dot shape, etc. Bump 33122 and locking block 331 can be integrally formed, or they can be manufactured separately and welded to the inner surface of opening 3311 of locking block 331.

[0117] When the locking block 331 is installed on the mounting screw 31 , the slot 31412 is sleeved on the protrusion 33122 to limit the rotation of the locking block 331 on the mounting screw 31 , thereby limiting the rotation of the mounting cap 32 on the external thread section 313 .

[0118] The stop portion 3141 adopts a slot 31412, and the mating portion 3312 adopts a protrusion 33122. The protrusion 33122 is mated and plugged with the slot 31412 to limit the rotation of the locking block 331 around the mounting screw 31, thereby limiting the rotation of the mounting cap 32 on the external thread section 313, thereby reducing the risk of loosening of the mounting cap 32 to a certain extent.

[0119] 10 and 12 , the stopper 3141 is located at one end of the external thread segment 313 away from the second end 312 , and the radius of the external thread segment 313 is greater than or equal to the maximum distance from the side of the stopper 3141 to the central axis of the mounting screw 31 .

[0120] The radius of the external thread segment 313 refers to the distance from the outer circumference of the external thread segment 313 to the central axis of the mounting screw 31 .

[0121] Since the stopper 3141 is provided on the peripheral side surface of the mounting screw 31 , the maximum distance from the side surface of the stopper 3141 to the central axis of the mounting screw 31 refers to the maximum distance from any point on the side surface of the stopper 3141 to the central axis of the mounting screw 31 .

[0122] The connecting hole 321 in the mounting cap 32 is threadedly connected to the external thread section 313, and the inner diameter of the connecting hole 321 of the mounting cap 32 is adapted to the radius of the external thread section 313. The stop portion 3141 is provided at the end of the external thread section 313 away from the second end 312, and the radius of the external thread section 313 is greater than or equal to the maximum distance from the side of the stop portion 3141 to the central axis of the mounting screw 31. The inner diameter of the connecting hole 321 in the mounting cap 32 is greater than or equal to the maximum distance from the side of the stop portion 3141 to the central axis of the mounting screw 31, so that the mounting cap 32 can pass through the stop portion 3141 and be connected to the external thread section 313.

[0123] The stop portion 3141 is provided at the end of the external thread segment 313 away from the second end 312 to facilitate the processing and manufacturing of the blocking portion; since the internal thread 3211 of the connecting hole 321 of the mounting cap 32 is adapted to be connected with the external thread segment 313, the inner diameter of the connecting hole 321 is equal to or similar to the radius of the external thread segment 313, and the radius of the external thread segment 313 is set to be greater than or equal to the maximum distance from the side of the stop portion 3141 to the central axis of the mounting screw 31, the stop portion 3141 can pass through the connecting hole 321 so that the internal thread 3211 is connected to the external thread segment 313, and then the mounting cap 32 is installed on the mounting screw 31.

[0124] Please refer to Figures 4 to 6. In some embodiments, the stop portion 3141 is provided at one end of the external thread segment 313 close to the second end 312. The radius of the external thread segment 313 is less than or equal to the minimum distance from the side of the stop portion 3141 to the central axis of the mounting screw 31.

[0125] The radius of the external thread segment 313 refers to the distance from the outer circumference of the external thread segment 313 to the central axis of the mounting screw 31 .

[0126] Since the stopper 3141 is provided on the peripheral side surface of the mounting screw 31 , the minimum distance from the side surface of the stopper 3141 to the central axis of the mounting screw 31 refers to the minimum distance from any point on the side surface of the stopper 3141 to the central axis of the mounting screw 31 .

[0127] Because the locking block 331 is mounted to the corresponding position of the stopper 3141 on the mounting screw 31, the shape and size of the opening 3311 in the locking block 331 match the corresponding section of the stopper 3141 on the mounting screw 31. The stopper 3141 is located at the end of the externally threaded segment 313 near the second end 312. The radius of the externally threaded segment 313 is less than or equal to the minimum distance from the side of the stopper 3141 to the central axis of the mounting screw 31. Therefore, the minimum distance from the mating portion 3312 in the opening 3311 of the locking block 331 to the central axis of the opening 3311 is greater than or equal to the radius of the externally threaded segment 313, allowing the locking block 331 to pass through the externally threaded segment 313 and connect with the corresponding section of the stopper 3141.

[0128] The stop portion 3141 is provided at one end of the external thread section 313 close to the second end 312. When mounted for use, the locking block 331 can be brought into contact with the carrying medium 90, thereby protecting the mounting cap 32. Since the locking block 331 is located at a position corresponding to the stop portion 3141, the opening 3311 on the locking block 331 needs to be adapted to fit the position of the mounting screw 31 corresponding to the stop portion 3141. The radius of the external thread section 313 is set to be less than or equal to the minimum distance from the side surface of the stop portion 3141 to the center axis of the mounting screw 31, so that the external thread section 313 can pass through the opening 3311, so that the opening 3311 reaches the stop portion 3141, so as to install the locking block 331 on the mounting screw 31 and connect the matching portion 3312 to the stop portion 3141.

[0129] In some embodiments, the opening 3311 forms an interference fit with the area of ​​the mounting screw 31 corresponding to the stop portion 3141. The inner surface of the opening 3311 is connected to the area of ​​the stop portion 3141 corresponding to the mounting screw 31 through an interference fit to secure the locking block 331 to the mounting screw 31. This can effectively prevent the locking block 331 from loosening, and thus effectively prevent the mounting cap 32 from loosening.

[0130] In some embodiments, the inner surface of the opening 3311 is bonded to the area of ​​the mounting screw 31 corresponding to the stop portion 3141. The inner surface of the opening 3311 is bonded to the area of ​​the mounting screw 31 corresponding to the stop portion 3141 to fix the locking block 331 on the mounting screw 31. This can, to a certain extent, provide a good anti-loosening effect on the locking block 331, and thereby provide a good anti-loosening effect on the mounting cap 32.

[0131] In some embodiments, a layer of glue can be applied to the inner surface of the opening 3311, and the locking block 331 can be connected with the area of ​​the mounting screw 31 corresponding to the stop portion 3141 by interference fit, and the inner surface of the opening 3311 can be bonded to the area of ​​the mounting screw 31 corresponding to the stop portion 3141 to improve the connection strength.

[0132] Please refer to Figures 6, 7 and 12. In some embodiments, a groove 3201 is provided on one of the locking block 331 and the mounting cap 32, and a protrusion 3202 that fits into the groove 3201 is provided on the other of the locking block 331 and the mounting cap 32.

[0133] The groove 3201 refers to a groove structure provided on an object, and the protrusion 3202 refers to a protrusion structure provided on an object.

[0134] A groove 3201 is provided on one of the locking block 331 and the mounting cap 32, and a protrusion 3202 is provided on the other. The groove 3201 and the protrusion 3202 engage with each other to achieve the connection between the locking block 331 and the mounting cap 32. As shown in Figures 6 and 7, the protrusion 3202 can be provided on the mounting cap 32, and the groove 3201 can be provided on the locking block 331. The protrusion 3202 engages with the groove 3201 to achieve the connection between the locking block 331 and the mounting cap 32. As shown in Figure 12, the groove 3201 can be provided on the mounting cap 32, and the protrusion 3202 can be provided on the locking block 331. The protrusion 3202 engages with the groove 3201 to achieve the connection between the locking block 331 and the mounting cap 32. In some other embodiments, a groove 3201 and a protrusion 3202 may be provided on the mounting cap 32 at the same time, and a protrusion 3202 and a groove 3201 may be provided on the locking block 331 accordingly, so that the connection between the locking block 331 and the mounting cap 32 is achieved through the cooperation between the protrusion 3202 and the groove 3201.

[0135] The connection between the locking block 331 and the mounting cap 32 is achieved by plugging and fitting the groove 3201 and the inserting protrusion 3202. The rotation of the mounting cap 32 must drive the locking block 331 to rotate, and then the locking block 331 is limited to rotate on the mounting screw 31, which can limit the rotation of the mounting cap 32 on the mounting screw 31, thereby preventing the mounting cap 32 from loosening.

[0136] In some embodiments, the locking block 331 and the mounting cap 32 may also be bonded together.

[0137] Referring to FIG. 3 to FIG. 7 , in some embodiments, the mounting structure 300 further includes a snap ring 34 disposed on the mounting screw 31 . The snap ring 34 is used to limit the locking block 331 from moving in a direction away from the mounting cap 32 .

[0138] Snap ring 34 refers to a ring-shaped device for connecting and fixing objects. It is usually made of metal or plastic.

[0139] A retaining ring 34 is provided, and the mounting cap 32 cooperates with the retaining ring 34 to limit the axial position of the locking block 331 along the mounting screw 31, so as to position and fix the locking block 331, so that the locking block 331 can better lock the mounting screw 31, thereby preventing the mounting cap 32 from loosening.

[0140] In some embodiments, a ring groove 315 is provided on the mounting screw 31 , and the snap ring 34 is clamped in the ring groove 315 .

[0141] The annular groove 315 refers to a groove structure provided on the mounting screw 31 , and the groove structure is provided around the circumferential side surface of the mounting screw 31 to form an annular shape.

[0142] An annular groove 315 is provided on the mounting screw 31 to facilitate positioning and installation of the snap ring 34 .

[0143] In some embodiments, a flared section 3313 is provided at one end of the opening 3311 of the locking block 331 away from the mounting cap 32 . When the locking block 331 abuts against the snap ring 34 , the snap ring 34 is accommodated in the flared section 3313 .

[0144] The expanded section 3313 is a section whose cross-sectional area is larger than the cross-sectional area of ​​the rest of the opening 3311. The cross-sectional area is a section perpendicular to the axial direction of the opening 3311.

[0145] A flared section 3313 is provided in the opening 3311 to accommodate the snap ring 34 , thereby protecting the snap ring 34 .

[0146] Please refer to Figures 13 and 14. In some embodiments, a first mounting hole 322 is opened on the side of the mounting cap 32, the adapter structure 314 includes a second mounting hole 3142 provided on the side of the first end 311, and the locking member 33 includes a connecting member 332 that is fitted and installed in the first mounting hole 322 and the second mounting hole 3142.

[0147] The first mounting hole 322 refers to a hole structure provided on the mounting cap 32 . The second mounting hole 3142 refers to a hole structure provided on the first end 311 of the mounting screw 31 .

[0148] The connecting member 332 refers to a structural member adapted to be inserted into the first mounting hole 322 and the second mounting hole 3142 . The connecting member 332 may be a rod-shaped member, a block-shaped member, etc. Of course, the connecting member 332 may also be a structural member such as a screw.

[0149] A connecting piece 332 is provided, which is installed in the first mounting hole 322 and the second mounting hole 3142 to fix the mounting cap 32 on the mounting screw 31. This can limit the axial movement of the mounting cap 32 along the mounting screw 31, and can also limit the rotation of the mounting cap 32 on the mounting screw 31. The structure is simple and easy to fix.

[0150] In some embodiments, the first mounting hole 322 can be provided through the mounting cap 32, while the second mounting hole 3142 can be provided through the first end 311 of the mounting screw 31. This allows the connector 332 to be inserted from either end of the first mounting hole 322 for easier assembly. Of course, the first mounting hole 322 can also extend to the connecting hole 321, while the second mounting hole 3142 can be a blind hole.

[0151] Please refer to Figures 3 to 5, 8 and 9. In some embodiments, the locking sleeve 35 is provided with a slide 351 for guiding the mounting screw 31 to rotate a set angle. The mounting screw 31 is provided with a guide pin 316, which extends into the slide 351.

[0152] The slideway 351 is a slot or hole structure provided on the locking sleeve 35. The guide pin 316 is a rod-shaped or block-shaped member protruding from the mounting screw 31. The guide pin 316 can be integrally formed with the mounting screw 31 for ease of manufacture. Alternatively, the guide pin 316 can be welded to the mounting screw 31.

[0153] The guide pin 316 extends into the slide 351 to guide the guide pin 316 to move through the slide 351, and then guide the mounting screw 31 to rotate a set angle. The set angle can be 60 degrees, 70 degrees, 80 degrees, 90 degrees, 100 degrees, 110 degrees, 120 degrees, etc., and can be set according to needs.

[0154] When the mounting screw 31 is pulled by tightening the screw 36 to move axially along the locking sleeve 35, the mounting screw 31 can be guided to rotate the set angle through the cooperation of the slide 351 and the guide pin 316, thereby driving the mounting cap 32 to rotate the set angle; when it is mounted for use, the mounting screw 31 is pulled toward the second end 312 to rotate the mounting cap 32 to the set angle so that the mounting cap 32 is mounted on the supporting medium 90; conversely, the mounting screw 31 is pushed toward the first end 311 to reverse the setting angle, and the mounting cap 32 is separated from the supporting medium 90, thereby achieving rapid mounting and separation.

[0155] In some embodiments, the slideway 351 includes an inclined section 3511 that is spirally extended on the locking sleeve 35, or the extending direction of the inclined section 3511 is inclined with respect to the axial direction of the locking sleeve 35. The inclined section 3511 is provided to guide the movement of the guide pin 316, thereby driving the mounting screw 31 to rotate by a set angle.

[0156] In some embodiments, the slide 351 also includes a first axial section 3512, which is extended along the axial direction of the locking sleeve 35. The first axial section 3512 extends from the end of the inclined section 3511 away from the tightening screw 36 toward a direction away from the tightening screw 36, so that when the guide pin 316 is in the first axial section 3512, it guides the mounting screw 31 to move axially.

[0157] In some embodiments, the slide 351 also includes a second axial section 3513, which is extended along the axial direction of the locking sleeve 35. The second axial section 3513 extends from one end of the inclined section 3511 close to the tightening screw 36 toward the direction close to the tightening screw 36, so that when the guide pin 316 is in the second axial section 3513, it guides the mounting screw 31 to move axially.

[0158] During mounting and assembly, the guide pin 316 is first positioned at the end of the first axial section 3512 away from the inclined section 3511, thereby moving the mounting cap 32 away from the locking sleeve 35. At this point, the length direction of the mounting cap 32 is aligned with the length direction of the rectangular hole 91, allowing the mounting cap 32 to pass through the rectangular hole 91. The second end 312 of the mounting screw 31 is then pulled, causing the guide pin 316 to first move along the first axial section 3512 to the inclined section 3511, correspondingly moving the mounting cap 32 toward the carrier medium 90. As the guide pin 316 moves along the inclined section 3511, it guides the mounting screw 31 to rotate, driving the mounting cap 32 to rotate, causing the length direction of the mounting cap 32 to be inclined or perpendicular to the length of the rectangular hole 91. The guide pin 316 then moves along the second axial section 3513, pulling the second end 312 of the mounting screw 31, causing the mounting cap 32 to move toward the carrier medium 90, thereby being mounted on the carrier medium 90, completing the mounting and assembly. During disassembly, the second end 312 of the mounting screw 31 is moved in the opposite direction so that the mounting cap 32 is moved away from the carrier medium 90 in a direction away from the locking sleeve 35, so as to separate the mounting cap 32 from the carrier medium 90. The mounting cap 32 is then rotated until its length direction is consistent with the length direction of the rectangular hole 91, and then the mounting cap 32 can be pulled out from the carrier medium 90 to complete the disassembly.

[0159] In some embodiments, the mounting structure 300 also includes an anti-rotation mechanism 37, which includes a sleeve 372 that limits the rotation of the tightening screw 36 and a stopper 371 that cooperates to limit the rotation of the sleeve 372. The stopper 371 is fixedly connected to the locking sleeve 35, and the sleeve 372 is slidably mounted on the tightening screw 36 along the axial direction of the tightening screw 36.

[0160] The sliding sleeve 372 refers to a sleeve structure that is sleeved on the tightening screw 36 away from the internal thread section 361 .

[0161] The stopper 371 is a structural component used to limit the rotation of the sliding sleeve 372. For example, the sliding sleeve 372 can be an annular member with external teeth, while the stopper 371 can be an annular member with internal teeth. The external and internal teeth cooperate to achieve the connection between the stopper 371 and the sliding sleeve 372. Of course, a groove structure can also be provided on the outer periphery of the sliding sleeve 372, and the stopper 371 can be a protruding tooth structure adapted to fit into the groove structure.

[0162] The stopper 371 is fixedly connected to the locking sleeve 35, for example, by screws, welding, or by forming the locking sleeve 35 and the stopper 371 into one piece. The sliding sleeve 372 is slidably mounted on the tightening screw 36, and the sliding sleeve 372 can be moved to connect or disconnect with the stopper 371. When the sliding sleeve 372 is disconnected from the stopper 371, the tightening screw 36 can be rotated, thereby pulling the mounting screw 31 to move. When the sliding sleeve 372 is in contact with the stopper 371, the stopper 371 can prevent the sliding sleeve 372 from rotating, thereby preventing the tightening screw 36 from rotating, thereby achieving an anti-rotation effect.

[0163] By fixing the stopper 371 on the locking sleeve 35 and fitting the sleeve 372 on the tightening screw 36, the sleeve 372 is connected to the stopper 371, and the stopper 371 can limit the rotation of the sleeve 372, thereby limiting the rotation of the tightening screw 36, and the tightening screw 36 is threadedly connected to the second end 312 of the mounting screw 31, thereby limiting the rotation of the mounting screw 31 and achieving an anti-rotation effect; and using a tool to push the sleeve 372 to slide on the tightening screw 36 to separate the sleeve 372 from the stopper 371, the tightening screw 36 can be rotated to push the mounting screw 31 to rotate and move axially.

[0164] In some embodiments, an elastic member 38 is installed in the locking sleeve 35 to elastically push the sliding sleeve 372 toward the stop member 371 .

[0165] The elastic member 38 is a structural member having elastic force and capable of elastic reset, and can be a spring, a spring sheet, an elastic tube, etc.

[0166] An elastic member 38 is provided. After the tool that pushes the sleeve 372 away from the stop member 371 is removed, the elastic member 38 can push the sleeve 372 to contact the stop member 371 to limit the rotation of the sleeve 372, thereby limiting the rotation of the tightening screw 36 and achieving an anti-rotation effect.

[0167] According to some embodiments of the present application, a mounting structure 300 is provided, comprising a locking sleeve 35, a mounting screw 31, a tightening screw 36, a mounting cap 32, a locking member 33, and a retaining ring 34. The locking sleeve 35 defines a cavity 350, which extends axially through the locking sleeve 35 at opposite ends. The mounting screw 31 has opposing first and second ends 311 and 312, with the second end 312 of the mounting screw 31 positioned within the cavity 350 and the first end 311 of the mounting screw 31 extending out of the locking sleeve 35. The tightening screw 36 is positioned within the locking sleeve 35 and has an internally threaded section 361, which is threadably connected to the second end 312 of the mounting screw 31. The mounting cap 32 is longer than its width and defines a connecting hole 321 adapted to connect to the first end 311 of the mounting screw 31. The first end 311 includes an externally threaded section 313. The connecting hole 321 is provided with an internal thread 3211 that is threadedly connected to the externally threaded section 313. The locking member 33 includes a locking block 331 connected to the mounting cap 32. The locking block 331 defines an opening 3311 for inserting the first end 311. The first end 311 is provided with a stopper 3141. The inner surface of the opening 3311 is provided with a mating portion 3312. The stopper 3141 mates with the mating portion 3312 to limit the rotation of the locking block 331 about the mounting screw 31. The stopper 3141 is provided at one end of the externally threaded section 313 near the second end 312. The radius of the externally threaded section 313 is less than or equal to the minimum distance between the side of the stopper 3141 and the central axis of the mounting screw 31. A groove 3201 is provided on one of the locking block 331 and the mounting cap 32, and an insertion protrusion 3202 is provided on the other of the locking block 331 and the mounting cap 32 to fit into the groove 3201. An annular groove 315 is provided on the mounting screw 31, and the snap ring 34 is retained in the annular groove 315. A flared section 3313 is provided at the end of the opening 3311 of the locking block 331 away from the mounting cap 32. When the locking block 331 abuts against the snap ring 34, the snap ring 34 is accommodated within the flared section 3313. The mounting structure 300 of the embodiment of the present application not only allows the second end 312 of the mounting screw 31 to be directly enlarged to enhance the structural strength of the second end 312 of the mounting screw 31, but also achieves a good anti-loosening effect for the mounting cap 32.
