Description

Technical Field

[0001] This application relates to the field of electronic technology, and more particularly to a connection structure and electronic device. Background Technology

[0002] External interfaces of electronic devices are critical channels for signal and data input and output, directly determining the stability of device operation. During long-term operation, factors such as self-vibration, cable gravity, accidental contact during maintenance, or improper plugging / unplugging can easily lead to loose interface connections. A loose interface can cause signal interruptions, unstable data transmission, and interference with normal device operation; in severe cases, it can directly damage the internal hardware of the electronic device. To address these issues, various interface protection connection structures have been designed in existing technologies, using clamping or snap-fit ​​methods to secure the connecting cables and mitigate the risk of loosening. However, existing interface protection structures typically use fixed-size clamping components or single-specification elastic structures, which cannot finely adjust the clamping force according to different cable diameters. When the cable diameter is small, excessive clamping force can easily cause crush damage to the cable sheath; when the cable diameter is large, insufficient clamping force makes effective fixation difficult, significantly reducing the protective effect. Furthermore, existing structures also have significant shortcomings in terms of ease of adjustment and adaptability, making it difficult to meet the diverse cable protection needs of different application scenarios. Summary of the Invention

[0003] This application provides a connection structure and an electronic device to at least solve the problem in the related art that the connection structure of the electronic device interface cannot adjust the clamping force according to the cable diameter.

[0004] This application provides a connection structure, including: The housing has an inlet and an outlet, and the housing has a mounting base for connecting electronic devices at the end with the outlet. An anti-loosening clamping assembly is installed at the inlet of the housing, the anti-loosening clamping assembly comprising: A fixing plate, which is installed at the inlet of the outer casing; A rotating disk is rotatably disposed within the fixed disk. The rotating disk and the fixed disk cooperate to form a through threading cavity in the middle. The rotating disk is provided with a plurality of circumferentially spaced guide grooves. The guide grooves are arc-shaped grooves with radially varying dimensions and are located on the outer periphery of the threading cavity. A clamping frame, one end of which is slidably disposed in the guide groove and the other end extends to the threading cavity, the clamping frame being arranged at intervals along the circumference of the rotating disk; An operating element is movably mounted on the fixed disk. One end of the operating element is located outside the fixed disk, and the other end passes through the inside of the fixed disk and is connected to the rotating disk in a transmission manner, so as to drive the rotating disk to rotate, causing the multiple clamping frames to be driven by the inner wall of the guide groove to move closer to each other to clamp the cable or move away from each other to release the cable.

[0005] The present invention also provides an electronic device, including the connection structure described in any of the above claims, wherein the electronic device is provided with an interface, the mounting base is fixed on the electronic device, and the outlet is connected to the interface.

[0006] This application utilizes the coaxial rotatable engagement of the rotating disk and the fixed disk to allow multiple circumferentially spaced clamping frames to synchronously undergo radial displacement under the guidance of an arc-shaped guide groove. As the rotating disk rotates, each clamping frame moves inwards along the guide groove, either approaching or moving outwards, thus achieving uniform clamping or releasing of the cable within the cable threading cavity. The circumferential distribution of multiple clamping frames ensures a balanced clamping force along the cable's circumference, preventing localized stress concentration and cable damage, and guaranteeing clamping stability and reliability. Furthermore, one end of the operating component is located outside the fixed disk, while the other end penetrates the interior and is connected to the rotating disk via a transmission mechanism. Users only need to operate the operating component externally to drive the rotating disk and move the clamping frames, eliminating the need to penetrate the internal structure, making operation convenient and intuitive. In addition, the arc-shaped guide groove precisely constrains the sliding trajectory of the clamp, making the clamp move smoothly and the trajectory controllable during movement. Users can adjust the degree of proximity or distance of the clamp by controlling the rotation amplitude of the operating component, thereby adapting to cables of different diameters and realizing flexible adjustment of clamping force. This improves the universal adaptability of the connection structure to diverse cables and effectively prevents signal interruption or hardware damage caused by loose cables at electronic device interfaces.

[0012] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0013] The embodiments of this application provide a connection structure for an electronic device, which will be described in detail below in conjunction with the structure and working principle of the connection structure.

[0014] like Figures 1 to 10As shown, the embodiment provides a connection structure, which is a protection and connection device for the external interface of electronic devices. It integrates cable clamping and anti-loosening functions with electronic device interface docking, preventing signal transmission from being affected by cable loosening due to external force. The electronic devices include at least one of the following: servers, network devices (e.g., switches, routers, firewalls), storage devices (e.g., NAS, disk arrays, storage controllers), computing terminals (e.g., desktop workstations), data center maintenance and security equipment (NVR network recorders, video encoders), and industrial control equipment (e.g., industrial PCs, industrial gateways, data acquisition controllers). Preferably, the electronic device is a server.

[0015] like Figures 1 to 5 As shown, the connection structure includes a housing 1 and an anti-loosening clamping assembly 2.

[0016] The housing 1 has an inlet and an outlet for the cable 4 to enter and exit. An anti-loosening clamping assembly 2 is installed at the inlet of the housing 1, and the outlet mates with the interface of the electronic device. A mounting base 131 is provided on the end of the housing 1 with the outlet, and the mounting base 131 is detachably fixed to the electronic device. The connection between the mounting base 131 and the interface of the electronic device can be either threaded or plug-in. The cable 4 can enter the housing 1 through the inlet, exit through the outlet, and then pass through the interface of the electronic device.

[0017] The anti-loosening clamping assembly 2 includes a fixed plate 21, a rotating plate 22, a clamping frame 24, and an operating component 23.

[0018] A fixed disk 21 is installed at the inlet of the outer casing 1, and a rotating disk 22 is rotatably disposed within the fixed disk 21. The rotating disk 22 and the fixed disk 21 cooperate to form a through-hole for threading. The threading cavity includes a first threading port 2112 located in the middle of the fixed disk 21 and a second threading port 223 located in the middle of the rotating disk 22. The first threading port 2112 and the second threading port 223 are axially connected. The rotating disk 22 has multiple circumferentially spaced guide grooves 222. The guide grooves 222 are arc-shaped grooves with varying radial dimensions and are located on the outer periphery of the threading cavity; that is, some areas of the guide grooves 222 are radially closer to the threading cavity, and some areas are radially farther away from the threading cavity. One end of a clamping frame 24 is slidably disposed within the guide groove 222. The other end of the clamping frame 24 extends to the threading cavity. The clamping frames 24 are spaced apart circumferentially along the rotating disk 22. The operating element 23 is movably mounted on the fixed disk 21. One end of the operating element 23 is located outside the fixed disk 21, and the other end passes through the inside of the fixed disk 21 and is connected to the rotating disk 22 for transmission. It drives the rotating disk 22 to rotate, so that multiple clamping frames 24 are driven by the inner wall of the guide groove 222 to move inward and move closer to each other to clamp the cable or move outward and move away from each other to release the cable.

[0019] During installation, the mounting base 131 of the outer casing 1 is connected and fixed to the interface of the electronic device. The cable 4 enters from the inlet of the outer casing 1, passes through the cable passage cavity, and exits from the outlet to connect to the interface of the electronic device. When it is necessary to clamp the cable 4, the user operates one end of the operating component 23 located outside the fixed plate 21. The operating component 23 drives the rotating plate 22 to rotate relative to the fixed plate 21 through its transmission connection with the rotating plate 22. When the rotating plate 22 rotates, it drives the multiple circumferentially spaced guide grooves 222 on it to rotate synchronously. Since one end of each clamping frame 24 is constrained to slide in the corresponding guide groove 222, the arc-shaped extension trajectory of the guide groove 222 guides the clamping frame 24 to move inward along the guide groove 222. The multiple clamping frames 24 simultaneously move closer to each other towards the center of the cable passage cavity, thereby forming a uniform radial clamping force on the cable 4 passing through the cable passage cavity. When it is necessary to loosen or replace cable 4, the user reverses the operation of the operating component 23, the rotating disk 22 rotates in the opposite direction, and each clamping frame 24 moves away from each other along the guide groove 222 in the outward direction, reducing or eliminating the clamping force, so that cable 4 can be freely inserted or pulled out.

[0020] In this embodiment, the rotating disk 22 and the fixed disk 21 are coaxially rotatably coupled, allowing multiple circumferentially spaced clamping frames 24 to synchronously move radially under the guidance of the arc-shaped guide groove 222. When the rotating disk 22 rotates, each clamping frame 24 moves inward along the guide groove 222, either moving closer to each other or moving outward, thereby achieving uniform clamping or loosening of the cable 4 inside the cable threading cavity. The circumferential distribution of multiple clamping frames 24 ensures that the clamping force acts evenly along the circumference of the cable 4, avoiding local stress concentration and damage to the cable 4, and ensuring the stability and reliability of the clamping. At the same time, one end of the operating member 23 is located outside the fixed disk 21, and the other end is inserted into the interior and connected to the rotating disk 22 for transmission. The user only needs to operate the operating member 23 externally to drive the rotating disk 22 to rotate and drive the clamping frames 24 to move, without having to go deep into the structure, making the operation convenient and intuitive. In addition, the arc-shaped guide groove 222 precisely constrains the sliding trajectory of the clamping frame 24, making the clamping frame 24 move smoothly and its trajectory controllable during movement. Users can adjust the degree of proximity or distance of the clamping frame 24 by controlling the rotation amplitude of the operating component 23, thereby adapting to cables 4 of different diameters and realizing flexible adjustment of clamping force. This improves the universal adaptability of the connection structure to diverse cables 4 and effectively prevents signal interruption or hardware damage caused by the loosening of cables 4 in electronic device interfaces.

[0021] It should be noted that the outer casing 1 has a box-shaped structure. One end of the operating component 23 is connected to the rotating disk 22 via a transmission connection, which can be a gear transmission connection, a lead screw transmission connection, or a worm gear transmission connection. The fixed disk 21 and the rotating disk 22 are annular disk structures with a certain thickness, and the outer diameter of the rotating disk 22 is smaller than the outer diameter of the fixed disk 21. The inner diameters of the first threading port 2112 and the second threading port 223 are the same. The operating component 23 is a rod-shaped or knob-shaped component. The guide groove 222 extends in an arc shape from the inner ring side near the threading cavity to the outer ring side.

[0022] Preferably, the guide groove 222 extends outward along an involute shape from the position of the rotating disk 22 near the second threading opening 223 to the outer peripheral edge near the rotating disk 22. The multiple guide grooves 222 extend in the same direction and for the same length. The multiple guide grooves 222 are evenly spaced circumferentially. The number of guide grooves 222 is at least three, and preferably, four.

[0023] Furthermore, the outer peripheral edge of the fixed disk 21 is provided with a through extension channel 213, which is tangential to the outer peripheral edge of the rotating disk 22. The other end of the operating member 23 is installed in the extension channel 213 and engages with the outer peripheral surface of the rotating disk 22 for transmission.

[0024] After cable 4 passes through the cable passage cavity, the operator drives the outer end of the operating component 23 to rotate. The operating component 23 transmits the rotational force to the outer circumference of the rotating disk 22 through the meshing point in the extension channel 213, causing the rotating disk 22 to rotate relative to the fixed disk 21. The arc-shaped guide groove 222 on the rotating disk 22 rotates accordingly and guides multiple clamping frames 24 to slide inward along the groove and approach each other. The free ends of each clamping frame 24 converge towards the center of the cable passage cavity to form a ring clamping force on the cable 4 to fix the cable 4. When it is necessary to loosen the cable 4, the outer end of the operating component 23 is driven in the opposite direction.

[0025] In this embodiment, a through-extension channel 213 tangent to the outer periphery of the rotating disk 22 is provided on the outer periphery of the fixed disk 21. The other end of the operating member 23 is installed in the extension channel 213 and meshes with the outer periphery of the rotating disk 22 for transmission. The driving force of the operating member 23 is transmitted to the outer periphery of the rotating disk 22 through the extension channel 213 instead of passing through the middle of the fixed disk 21. This ensures that the operating member 23 and its transmission structure are completely arranged in the outer periphery of the fixed disk 21, without occupying the internal space of the threading cavity formed by the cooperation between the fixed disk 21 and the middle of the rotating disk 22, thus ensuring the unobstructed flow of the threading cavity. At the same time, the operating member 23 only occupies the space of the channel cross-section in the extension channel 213. Compared with the method of directly driving the rotating disk 22 to rotate from the middle through the rotating shaft, the overall structure is more compact. Moreover, the through-extension channel 213 makes the installation of the operating member 23 convenient and can smoothly drive the clamping frame 24 to move.

[0026] It should be noted that the outer circumferential surface of the rotating disk 22 is provided with a first tooth 221. The extension channel 213 is a straight channel, and the cross-sectional shape of the extension channel 213 can be replaced by a circle or a rectangle. One end of the operating member 23 is located outside one end of the extension channel 213, and the peripheral wall of the other end is provided with a helical second tooth 232, and the other end can pass through to the outside of the other end of the extension channel 213. The second tooth 232 meshes with the first tooth 221 for transmission connection. An operating part 231 is formed on one end of the operating member 23.

[0027] Furthermore, the fixed disk 21 has an internal cavity for accommodating the rotating disk 22. The fixed disk 21 has multiple circumferentially spaced and radially extending sliding grooves 2111, which axially penetrate the fixed disk 21 and connect to the accommodating cavity. One end of the clamping frame 24 passes through the guide groove 222 and can move along the sliding groove 2111. When the rotating disk 22 rotates, the clamping frame 24 moves within the guide groove 222 and the sliding groove 2111.

[0028] In this embodiment, by setting a sliding groove 2111 that extends radially and passes through axially on the fixed disk 21, one end of the clamping frame 24 is simultaneously inserted into the guide groove 222 and the sliding groove 2111 of the rotating disk 22. The sliding groove 2111 provides precise guiding constraint for the radial movement of the clamping frame 24. When the rotating disk 22 rotates and drives the clamping frame 24 to move along the guide groove 222, the clamping frame 24 can stably slide radially inward or outward relative to the fixed disk 21 under the guidance of the sliding groove 2111, avoiding the clamping frame 24 from shifting or shaking during the movement, ensuring the synchronicity and movement accuracy of multiple clamping frames 24 when they approach the center of the cable passage cavity, thereby achieving uniform and reliable clamping of the cable 4.

[0029] The fixed plate 21 includes a first ring portion 211 and a second ring portion 212, with the second ring portion 212 integrally connected to the outer periphery of the first ring portion 211. The first ring portion 211 and the second ring portion 212 have internal accommodating cavities for accommodating the rotating plate 22, and these accommodating cavities communicate with the threading cavity. The first ring portion 211 has multiple circumferentially spaced sliding grooves 2111, which axially penetrate the first ring portion 211 and communicate with the accommodating cavity. The sliding grooves 2111 extend radially along the first ring portion 211. One end of the clamping frame 24 passes through the guide groove 222 and can move along the sliding groove 2111. When the rotating plate 22 rotates, the clamping frame 24 moves within the guide groove 222 and the sliding groove 2111.

[0030] The thickness of the second ring portion 212 is greater than the thickness of the first ring portion 211. The receiving cavity of the fixed disk 21 includes an annular chamber and a limiting groove 2121. The annular chamber is coaxially arranged with the first ring portion 211 and is formed inside the first ring portion 211. The limiting groove 2121 is formed on the inner ring side of the second ring portion 212 and communicates with the annular chamber. The outer peripheral edge of the rotating disk 22 is fitted into the opening of the limiting groove 2121, and the first tooth 221 is movably located inside the limiting groove 2121. The first ring portion 211 and the second ring portion 212 are integrally connected.

[0031] The clamping frame 24 includes a pressing plate 241, a connecting arm 242, a sliding block 243, and a sliding rod 244.

[0032] The extrusion plate 241 extends into the threading cavity. Connecting arms 242 are respectively positioned on both sides of the fixed plate 21 along its axial direction, with one end of each arm connected to one end of the extrusion plate 241 along its extension direction. Sliding blocks 243 are connected to the other ends of the two connecting arms 242 and slidably positioned within the sliding groove 2111. A sliding rod 244 passes through the guide groove 222, with both ends connected to the two sliding blocks 243. The sliding groove 2111 is an axially continuous through groove. The two sliding blocks 243 are positioned in the two axial openings of the same sliding groove 2111.

[0033] In this embodiment, the clamping frame 24 is configured to include a pressing plate 241, a connecting arm 242, a sliding block 243, and a sliding rod 244. The connecting arm 242 is respectively disposed on the two side walls of the fixed disk 21 along the axial direction and connects the pressing plate 241 and the sliding block 243. The pressing plate 241 is located in the wire-passing cavity and the clamping frame 24 is distributed on both sides of the fixed disk 21 along the axial direction. The sliding rod 244 passes through the guide groove 222 and connects the two sliding blocks 243, connecting the two sliding blocks 243 into one unit. When the rotating disk 22 rotates, the sliding rod 244 drives the two sliding blocks 243 to move stably in the sliding groove 2111 through both ends. Then, the connecting arm 242 drives the pressing plate 241 to move synchronously inward or outward. This ensures that the pressing plate 241 is subjected to balanced force and moves synchronously on both sides during the movement, avoiding deviation or shaking caused by force on one side, and improving the stability and reliability of the clamping frame 24 in clamping the cable 4. Meanwhile, the sliding block 243 is located in the sliding groove 2111 on both sides of the fixed plate 21. The structure of the sliding rod 244 connecting the two sliding blocks 243 makes the clamping frame 24 form symmetrical support on both sides of the fixed plate 21, which further enhances the structural rigidity and stability of the extrusion plate 241 when clamping the cable 4.

[0034] It should be noted that the extrusion plate 241 is an arc-shaped strip extending circumferentially and axially along the fixed disk 21. The connecting arm 242 is a strip extending radially along the fixed disk 21. The sliding block 243 can be partially or completely inserted into the sliding groove 2111. The cross-section of the sliding rod 244 is circular or elliptical.

[0035] Preferably, there are two clamping frames 24. Each clamping frame 24 includes a pressing plate 241, four connecting arms 242, four sliding blocks 243, and two sliding rods 244. One end of two connecting arms 242 is circumferentially spaced and connected to the outer wall of one axial end of the pressing plate 241, and one end of the remaining two connecting arms 242 is circumferentially spaced and connected to the outer wall of the other axial end of the pressing plate 241. The other ends of the four connecting arms 242 are respectively connected to the sliding blocks 243, which protrude towards the annular cavity and are embedded in the sliding groove 2111. Sliding rods 244 are connected between two axially symmetrical sliding blocks 243.

[0036] The anti-loosening clamping assembly 2 also includes a plug-in plate 25, which is connected to one axial end of the fixed plate 21. The inner wall of the housing 1 is provided with a plug-in groove 112 that matches the plug-in plate 25. The plug-in plate 25 can be inserted into the plug-in groove 112 through the inlet, thereby fixing the anti-loosening clamping assembly 2 at the inlet of the housing 1.

[0037] like Figures 6 to 10 As shown, the outer casing 1 includes at least a first casing 11, a second casing 12, and a third casing 13. The first casing 11 and the second casing 12 are detachably connected and form an inlet at the connection point. The third casing 13 is located at the opening of the first casing 11 and the second casing 12 away from the inlet, and an outlet is located on the third casing 13. The inlet and outlet are located at opposite ends of the outer casing 1.

[0038] The inner wall of the outer casing 1 is provided with an anti-pull assembly 3. The anti-pull assembly 3 includes multiple rotating wheel structures. The multiple rotating wheel structures are arranged radially at intervals along the threading cavity, and adjacent rotating wheel structures are staggered in the axial direction of the threading cavity. After being clamped by the clamping frame 24, the cable 4 is sequentially wound around the rotating wheel structure and then exits through the outlet. The cable 4 is wound in a serpentine shape. The cable 4 is sequentially wound around the peripheral walls of the multiple axially staggered rotating wheel structures to form a spiral path. The multiple rotating wheel structures can slide along the axial direction of the threading cavity under force or reset after the force is removed.

[0039] In this embodiment, the outer casing 1 is configured as a detachable assembly of a first casing 11, a second casing 12, and a third casing 13. The first casing 11 and the second casing 12 form an inlet at their connection, and the third casing 13 is located at an open area away from the inlet and has an outlet. This allows the outer casing 1 to be disassembled for easy insertion, replacement, and maintenance of the cable 4. Simultaneously, an anti-pull assembly 3 is provided on the inner wall of the outer casing 1. Multiple rotating wheels 33 are arranged radially at intervals along the cable passage cavity, with adjacent rotating wheels 33 axially staggered. The cable 4 is spirally wound around the peripheral walls of each rotating wheel 33. When the cable 4 is pulled, the rotating wheels 33 rotate relative to the cable 4 to release stress, and adjacent rotating wheels 33 move in opposite directions along the axial direction of the cable passage cavity to disperse the pulling force. This allows the pulling force to be buffered and dissipated step by step through the rotation and axial displacement of multiple rotating wheels 33, reducing the concentrated effect of the pulling force on the cable 4 and lowering the risk of damage to the cable 4 due to accidental pulling. In addition, the design of the rotating wheel 33 being able to slide back and forth along the axial direction of the cable-threading cavity under force ensures that the anti-pull component 3 does not obstruct the normal threading of the cable 4 when not in use, thus balancing the protective function with the convenience of threading the cable 4.

[0040] It should be noted that the first housing 11, the second housing 12, and the third housing 13 are connected by a quick-release mechanism. The first housing 11 includes a first arc plate and a first end plate, with the first end plate connected to one end of the first arc plate. The second housing 12 includes a second arc plate and a second end plate, with the second end plate connected to one end of the second arc plate. The other ends of the first and second arc plates are fastened together to form an opening, and the third housing 13 is fixedly disposed at the opening. A mounting base 131 is formed on the outer peripheral edge of the third housing 13. The third housing 13 has a flat plate structure.

[0041] The anti-pull assembly 3 on the inner sidewalls of the first housing 11 and the second housing 12 includes multiple sets of guide grooves 311. The guide grooves 311 are arranged in groups, corresponding one-to-one with the rotating wheel structure. The multiple sets of guide grooves 311 are arranged side-by-side along the radial direction of the threading cavity. Each guide groove 311 is a straight groove or an arc-shaped groove extending along the axial direction of the threading cavity. Both ends of the rotating wheel structure can slide along the guide grooves 311 on the first housing 11 and the second housing 12, respectively.

[0042] In this embodiment, multiple guide grooves 311 are arranged radially side-by-side on the inner sidewalls of the first housing 11 and the second housing 12, respectively. The two ends of the rotating wheel structure are slidably disposed within the guide grooves 311 of the first housing 11 and the second housing 12. The guide grooves 311 limit the two ends of the rotating wheel 33, ensuring that when subjected to pulling force, the two ends of the rotating wheel 33 slide stably along the guide grooves 311 in the axial direction without dislodging. This guarantees that the movement trajectory of the rotating wheel 33 during axial reciprocating movement is controlled and does not detach from the housing. Thus, multiple rotating wheels 33 can move in the opposite direction axially under the constraint of the guide grooves 311 to disperse the pulling force, ensuring that the anti-pull assembly 3 continuously and effectively buffers and protects the cable 4 during pulling. Simultaneously, the radially arranged guide grooves 311 ensure that each rotating wheel 33 corresponds to an independent guide path, and the sliding of each rotating wheel 33 does not interfere with each other, improving the overall movement stability and reliability of the anti-pull assembly 3.

[0043] Furthermore, the anti-pull assembly 3 also includes a base 31 and a first elastic element 34. Multiple guide grooves 311 are respectively disposed on the base 31, and the base 31 is respectively disposed on the inner sidewalls of the first housing 11 and the second housing 12 opposite to each other.

[0044] The rotating structure includes a rotating wheel 33 and a movable seat 32. The movable seats 32 are slidably disposed in guide grooves 311, and the two ends of the rotating wheel 33 are detachably mounted in the opposing movable seats 32 on the first housing 11 and the second housing 12, respectively. First elastic members 34 connect one end of the guide groove 311 and the movable seat 32, and the first elastic members 34 in adjacent guide grooves 311 are located at different ends of the guide groove 311. In the guide groove 311 near the threading cavity, the first elastic member 34 connects the end of the guide groove 311 near the threading cavity and the movable seat 32 within that guide groove 311. In the next adjacent guide groove 311, the first elastic member 34 connects the end of the guide groove 311 away from the threading cavity and the corresponding movable seat 32.

[0045] In this embodiment, the two ends of the rotating wheel 33 are detachably installed in the movable seats 32 in the guide grooves 311 on the first housing 11 and the second housing 12, respectively, so that the rotating wheel 33 and the movable seats 32 form a separable connection relationship. When it is necessary to replace the cable 4 or maintain the anti-pull component 3, the rotating wheel 33 can be removed from the movable seats 32 after disassembling the first housing 11 and the second housing 12, which reduces the maintenance difficulty and improves the disassembly and assembly efficiency. Meanwhile, by connecting a first elastic element 34 between one end of the guide groove 311 and the movable seat 32, and with the first elastic elements 34 in adjacent guide grooves 311 located at different ends of the guide groove 311, when the cable 4 is pulled, the rotating wheel 33 drives the movable seat 32 to slide along the guide groove 311 and causes the first elastic element 34 to undergo elastic deformation to store energy. The first elastic element 34 converts the pulling force into elastic potential energy for buffering. Because the first elastic elements 34 are located at different ends, the adjacent rotating wheels 33 move in opposite directions along the guide groove 311 to disperse the pulling force, thereby reducing the direct effect of the pulling force on the cable 4 and reducing the risk of the cable 4 being damaged due to pulling.

[0046] The first elastic element 34 is a spring. The base 31 is a rectangular platform, and the top of the movable seat 32 is provided with a rotating hole 321, in which the rotating wheel 33 is rotatably disposed. The movable seat 32 is a rectangular block. The rotating wheel 33 includes a rotating rod and a wheel body, with the wheel body sleeved on the outer periphery of the rotating rod.

[0047] The first housing 11 has a positioning block 113 on its end face, and the second housing 12 has a positioning hole 122 that matches the positioning block 113 on its end face, with the positioning block 113 inserted into the positioning hole 122.

[0048] like Figures 9 to 10 As shown, the outer wall of the first housing 11 is provided with a protruding first connecting seat 111, and the second housing 12 is provided with a second connecting seat 121 that matches the first connecting seat 111. A slot 1111 is provided between the two ends of the first connecting seat 111 that are near and away from the second connecting seat 121. The second connecting seat 121 is provided with two lever-type engaging structures, which can either be brought close to each other and engaged with the slot 1111, or moved away from each other and disengaged from the slot 1111.

[0049] In this embodiment, a protruding first connecting seat 111 is provided on the outer wall of the first housing 11, and a protruding second connecting seat 121 is provided on the second housing 12, with the second connecting seat 121 matching the first connecting seat 111. A slot 1111 is provided on the first connecting seat 111, and two lever-type connecting structures that can move closer or further apart are provided on the second connecting seat 121. This allows the first housing 11 and the second housing 12 to be quickly assembled and connected through the snap-fit ​​of the two connecting seats. The user only needs to operate the lever-type connecting structures to move closer together to insert them into the slot 1111 to complete the snap-fit, and operate the lever-type connecting structures to move further apart to disassemble them from the slot 1111. The housing 1 can be quickly assembled and disassembled without the need for additional tools, and the user can easily use the lever 1212 to move it to complete the assembly and disassembly, improving the convenience and efficiency of assembling and disassembling the housing 1.

[0050] The first connecting seat 111 has an inclined guide slope at one end near the second connecting seat 121, and the end of the first connecting seat 111 near the second connecting seat 121 is a pointed end. Two slots 1111 are formed on the periphery between the two ends of the first connecting seat 111. The pointed guide slope extends to the edge of the slot 1111. The second connecting seat 121 is provided with a mounting groove 1211, which penetrates the end face of the second connecting seat 121 facing the first connecting seat 111 and the side face of the second connecting seat 121.

[0051] The lever-locking structure includes a lever 1212, a locking block 1213, and a second elastic member 1214. The locking block 1213 is slidably disposed in the mounting groove 1211 on the end face of the second connecting seat 121 and is detachably connected to the locking groove 1211. The second elastic member 1214 connects the mounting groove 1211 and the locking block 1213. The lever 1212 is connected to the locking block 1213 and extends through to the outside of the side wall of the second connecting seat 121, which can drive the locking block 1213 to move.

[0052] In this embodiment, an inclined guide slope is provided at one end of the first connecting seat 111 near the second connecting seat 121 and extends to the edge of the slot 1111. An installation groove 1211 is provided on the second connecting seat 121, penetrating the end face and the side face. The locking block 1213 is slidably disposed in the installation groove 1211. The lever 1212 is connected to the locking block 1213 and passes through to the outside of the side wall of the second connecting seat 121. The second elastic member 1214 is connected between the installation groove 1211 and the locking block 1213. The locking block 1213 is pressed against the slot 1111. When the first connecting seat 111 is inserted into the installation groove 1211 of the second connecting seat 121, the guide slope automatically guides the two locking blocks 1213 to compress the second elastic member 1214 and slide into the slot 1111. After the second elastic member 1214 rebounds, it presses and locks the locking block 1213 into the slot 1111, thus achieving quick locking. The user only needs to move the external operating lever 1212 to drive the two locking blocks 1213 to compress the second elastic element 1214, so that the locking blocks 1213 can disengage from the slot 1111 to complete the disassembly. The first housing 11 and the second housing 12 can be quickly assembled and disassembled without the need for additional tools, which improves the convenience of disassembly and assembly operations.

[0053] Two locking blocks 1213 are arranged adjacently in the mounting groove 1211 along the axial direction of the threading cavity. Two second elastic elements 1214 are connected to the opposite ends of the two locking blocks 1213. The upper parts of the adjacent ends of the two locking blocks 1213 are respectively provided with cut surfaces to guide the tip of the first connecting seat 111 into the space between the two locking blocks 1213. The first connecting seat 111 is provided with locking grooves 1111 that match the number and position of the locking blocks 1213. A lever 1212 is connected to the radial side of the locking blocks 1213. The second elastic elements 1214 are springs.
