Description

Technical Field

[0001] This utility model relates to the field of connecting component technology, and in particular to a locking assembly and a telescopic fence. Background Technology

[0002] Currently, in public places such as subways, shopping malls, conference venues, and exhibition halls, a type of fence with retractable straps is commonly used, such as... Figure 1 and Figure 2 As shown, this type of fence generally includes multiple bases 1, at least one telescopic belt assembly 2, and a locking assembly 3. Each pair of bases 1 is connected by a telescopic belt assembly 2. The fixed part 201 of the telescopic belt assembly 2 is fixed to one of the bases 1, and the movable part 202 of the same telescopic belt 2 is locked and fixed to another base 1 by the locking assembly 3.

[0003] Specifically, these locking assemblies 3 include a fixing member 301 and a separable member 302. The fixing member 301 is disposed on the base 1, and the separable member 302 is used to cooperate with the fixing member 301 and can be detachably connected to the fixing member 301. The separable member 302 is connected to the movable part 202 of the telescopic belt assembly 2. Furthermore, in order to facilitate separation and assembly, the fixing member 201 and the separable member 202 are usually connected by means of a longitudinally arranged slide groove 5 and slide rail 4.

[0004] In some existing technologies, in order to improve the stability of the connection between the separable part and the fixed part and to avoid the accidental loosening of the locking assembly, some hook structures are further used for auxiliary fixation. For example, the Chinese utility model patent with announcement number CN215405729U and title "A quick connection handle for a telescopic fence" discloses the main body of the connection handle. The main body of the connection handle consists of a telescopic rope, a locking device, a connecting device and a tube body. A retainer is installed inside the locking device. An elastic arm is installed on one side of the retainer and a fixed arm is installed on the other side of the retainer. A barb is installed at the bottom end of the elastic arm. A bolt is installed at one end of the fixed arm. A sliding groove is installed at one end of the locking device and a connecting device is installed at the other end of the locking device.

[0005] The working principle of this connecting handle is as follows: a retainer is designed at the bottom. After the retaining head is inserted downwards, its own elasticity and barbs will lock the connecting device. When it needs to be pulled out, the barbs on the retainer can be turned to pull it out.

[0006] This type of locking assembly still presents operational inconveniences, requiring the hook to be turned from below to unlock; due to varying hand strength among different individuals, the locking force required for the hook is relatively high; furthermore, these fences often need to be frequently disassembled for relocation and adjustment of the enclosure area, and the frequent unlocking and locking processes can cause wear and tear on the hook, leading to fatigue damage such as deformation or even fatigue fracture.

[0007] Therefore, there is a need to propose a locking assembly with a simpler structure and a longer service life, as well as its application. Utility Model Content

[0008] In order to overcome at least one of the defects described in the prior art, the first objective of this utility model is to provide a locking assembly to solve the problems of inconvenient installation and removal and limited service life of the locking assembly in the prior art.

[0009] The second objective of this invention is to provide a telescopic fence that utilizes a new locking assembly to solve the problems of inconvenient installation and removal and limited service life caused by the locking assembly in existing telescopic fences.

[0010] The technical solution adopted by this utility model to solve its problem is:

[0011] According to one aspect of the present invention, the present invention provides a locking assembly, including a detachably connected fixed member and a detachable member, wherein the fixed member is provided with one of a slide rail and a slide groove; the detachable member is provided with the other of the slide rail and the slide groove, wherein the slide rail and the slide groove are slidably engaged, wherein the fixed member is fixedly provided with a first magnetic attracting member; and the detachable member is fixedly provided with a second magnetic attracting member.

[0012] When the fixed component and the separable component move to the locking position through the cooperation of the slide rail and the slide groove, the position of the first magnetic attractor corresponds to the position of the second magnetic attractor and they attract each other with magnetic force.

[0013] In some optional embodiments, the separable component has a hollow cavity, and the side surface of the separable component has a strip-shaped through groove that communicates with the hollow cavity.

[0014] In some optional embodiments, the fixing member has a first mounting groove for mounting the first magnetic element;

[0015] The detachable component has a second mounting groove for mounting the second magnetic component;

[0016] At the locked position, the center lines of the first mounting slot and the second mounting slot are arranged parallel to each other, and at least a portion of the projections of the first mounting slot and the second mounting slot overlap on a projection plane perpendicular to their center lines.

[0017] In some alternative embodiments, in the locked position, the center lines of the first mounting slot and the second mounting slot are coaxially aligned.

[0018] In some optional embodiments, the separable component further includes a body and a cover component that is separably connected to the body. The hollow cavity is formed on the body, and one of the upper and lower ends of the body has an opening communicating with the hollow cavity. The cover component is located at the opening and is used to close the opening.

[0019] In some alternative embodiments, the second magnetic element is fixed to the cover member.

[0020] In some optional embodiments, the cover member is provided with a hook, and the side wall of the main body is provided with a groove that engages with the hook, the groove extending through the outside of the main body.

[0021] In some optional embodiments, the cover member is provided with a limiting protrusion, and the main body is provided with an abutting protrusion corresponding to the limiting protrusion. The abutting protrusion can abut against the limiting protrusion, and when the limiting protrusion and the abutting protrusion are in contact, the hook can be engaged into the slot.

[0022] In some alternative embodiments, the outer surface of the separable member is provided with an anti-slip structure, which includes multiple raised and recessed grooves on the separable member, the multiple raised and recessed grooves being arranged in parallel at intervals, and / or, a groove is provided on one of the two opposite sides of the separable member.

[0023] In some alternative embodiments, the slide rail has a T-shaped cross-section, and the front and rear ends of the slide rail are provided with rounded chamfers.

[0024] According to another aspect of the present invention, the present invention provides a telescopic fence, including a base and a telescopic belt assembly. The telescopic belt assembly includes a fixed part, a movable part, and any of the above-mentioned locking components. The fixed part is fixed to the upper end of the base, and the movable part is fixedly connected to a separable component of the locking component. The fixed component in the locking component is fixed to the base.

[0025] As can be seen from the above technical solution, the embodiments of this utility model have at least the following advantages and positive effects:

[0026] 1) In the proposed locking assembly, by employing a first magnetic suction member and a second magnetic suction member that attract each other, the separable component is fixed to the fixed component at the locking position by the mutual attraction between the first magnetic suction member and the second magnetic suction member, thereby achieving a stable connection. When disassembly is required, only force needs to be applied to make the second magnetic suction member on the separable component and the first magnetic suction member on the fixed component misalign with each other, so that the magnetic attraction between the two is weakened, and disassembly is achieved. The disassembly process will not cause functional wear to the locking structure, which significantly improves the service life of the locking assembly. In addition, it is easy to install and remove, simple to manufacture, and low in cost.

[0027] 2) In the locking assembly, the separable component is also provided with a cover component, which is connected by a snap-fit ​​structure, so that the hollow cavity inside the separable component can be opened or closed, which is convenient for installing other components. Furthermore, the second magnetic component is installed on the cover component, which also helps to reduce manufacturing difficulty and simplify the structure.

[0028] 3) The proposed telescopic fence uses a new locking assembly, which makes the telescopic fence easy to install and remove, and facilitates the rapid construction and dismantling of the telescopic fence. In addition, the locking assembly used has low damage during the installation and removal process, which extends the overall service life of the telescopic fence. Attached Figure Description

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0042] Figure 1 This is a structural diagram of a telescopic fence in the prior art; Figure 2 This is a structural diagram of a prior art locking assembly.

[0043] Example 1

[0044] See Figures 3 to 8 This utility model discloses a locking assembly 3, including a detachable fixed component 301 and a detachable component 302. The fixed component 301 is provided with one of a slide rail 4 and a slide groove 5; the detachable component 302 is provided with the other of the slide rail 4 and slide groove 5. The slide rail 4 and slide groove 5 are slidably engaged, and a locking position is achieved along the sliding trajectory of the slide rail 4 and slide groove 5. (See reference...) Figure 3 and Figure 5At the locked position, the fixing member 301 and the separable member 302 are locked together.

[0045] For example, in some optional embodiments, the slide rail 4 is disposed on the fixed member 301, and the slide groove 5 is disposed on the slide groove 5, see reference. Figure 8 The separable component 302 is assembled with the fixed component 301 along the Z direction.

[0046] In some other alternative embodiments, the slide rail 4 may also be disposed on the separable member 302, while the slide groove 5 may be disposed on the fixed member 301.

[0047] See Figure 5 Furthermore, a first magnetic attractor 6 is fixedly provided on the fixing member 301, and a second magnetic attractor 7 is fixedly provided on the separable member 302; and at the locked position, the position of the first magnetic attractor 6 corresponds to the position of the second magnetic attractor 7 and they attract each other with magnetic force.

[0048] The first magnetic attractor 6 and the second magnetic attractor 7 attract each other magnetically, locking the fixed member 301 and the separable member 302 in the locked position, thus achieving fixation. When at least one of the fixed member 301 and the separable member 302 is subjected to external force, causing the fixed member 301 and the separable member 302 to slide against each other, the first magnetic attractor 6 and the second magnetic attractor 7 will be misaligned, weakening the magnetic attraction between them, and thus the fixed member 301 and the separable member 302 can be separated. In this way, the structure of the locking assembly 3 is simplified and the assembly and disassembly are completed. Furthermore, during the assembly and disassembly process, the functional damage to each component is reduced, the possibility of fatigue damage is reduced, and the service life of the locking assembly 3 is extended.

[0049] See Figures 3-5 In some optional embodiments, a hollow cavity 3021 is provided inside the separable component 302, and a strip-shaped through groove 3022 communicating with the hollow cavity 3021 is opened on the side surface of the separable component 302.

[0050] The provided slot 3022 allows the locking assembly 3 to be connected to other components it is used with. For example, when the locking assembly 3 is used in a telescopic fence in the prior art and the locking assembly of the telescopic fence in the prior art is replaced, the movable part 202 of the telescopic belt assembly 2 can be connected to the hollow cavity 3021 through the slot 3022 to realize the connection between the telescopic belt assembly 2 and the locking assembly 3.

[0051] See Figure 3 , Figure 4 , Figure 5 , Figure 7The fixing component 301 has a through hole 3012 reserved to provide conditions for fixing the fixing component 301 to the base 1 of the telescopic fence.

[0052] See Figure 5 , Figure 6 In some optional embodiments, the fixing member 301 is provided with a first mounting groove 3011 for mounting the first magnetic member 6; the separable member 302 is provided with a second mounting groove 3023 for mounting the second magnetic member 7.

[0053] At the locked position, the center line of the first mounting groove 3011 and the center line of the second mounting groove 3023 are arranged parallel to each other, and at least a portion of the projection of the first mounting groove 3011 and the second mounting groove 3023 overlaps on the projection plane perpendicular to their center lines.

[0054] A first mounting groove 3011 and a second mounting groove 3023 are respectively provided for the first magnetic component 6 and the second magnetic component 7. The first magnetic component 6 is installed in the first mounting groove 3011 and the second magnetic component 7 is installed in the second mounting groove 3023. The first magnetic component 6 and the first mounting groove 3011, and the second magnetic component 7 and the second mounting groove 3023 are fixed by interference fit or by adhesive, so that the connection is stable and avoids falling off.

[0055] See Figure 5 Specifically, at least one of the first mounting slot 3011 and the second mounting slot 3023 is a blind slot. After the first magnetic 6 and the second magnetic 7 are installed in the first mounting slot 3011 and the second mounting slot 3023 respectively, there is a certain gap between the first magnetic 6 and the second magnetic 7 in the locked position. This gap can be determined according to the magnitude of the magnetic attraction force between the first magnetic 6 and the second magnetic 7. For example, it can be selected in the range of 0.5mm-10mm. The relationship between the gap and the magnetic force of the first magnetic 6 and the second magnetic 7 is: the greater the magnetic force of the first magnetic 6 and the second magnetic 7, the larger the gap between the first magnetic 6 and the second magnetic 7 is allowed to be.

[0056] Furthermore, the size of the gap is also related to the magnetic conductivity of the materials of the fixing member 301 and the separable member 302. If the magnetic conductivity of the materials of the fixing member 301 and the separable member 302 is stronger, the allowable gap can be increased; otherwise, if the magnetic conductivity of the fixing member 301 and the separable member 302 is weak, the gap between the first magnetic suction member 6 and the second magnetic suction member 7 needs to be appropriately reduced.

[0057] The first magnetic 6 and the second magnetic 7 are separated by a reserved gap, and direct contact between the first magnetic 6 and the second magnetic 7 is not allowed. This ensures that the first magnetic 6 and the second magnetic 7 can maintain sufficient magnetic attraction, and also avoids the problem of separation caused by the first magnetic 6 and the second magnetic 7 sticking together, which facilitates quick disassembly.

[0058] See Figure 5 , Figure 6 The first mounting groove 3011 is a blind groove, while the second mounting groove 3023 is a through groove. The second magnetic member 7 includes a cylindrical part 701 and a shoulder part 702. The cylindrical part 701 cooperates with the second mounting groove 3023, and the shoulder part 702 abuts against the separable member 302. This structural design facilitates installation.

[0059] The first mounting groove 3011 and the second mounting groove 3023 have at least a portion of their projections overlapping on a projection plane perpendicular to their center lines, which ensures that at the locking position, the first magnetic member 6 and the second magnetic member 7 have magnetic attraction to provide locking capability.

[0060] The first magnetic attractor 6 and the second magnetic attractor 7 are made of materials that can attract each other magnetically. For example, one of the first magnetic attractor 6 and the second magnetic attractor 7 is a magnet and the other is a ferromagnet; or both are magnets, but the magnetism of their opposite sides is opposite.

[0061] See Figure 5 In some optional embodiments, in the locked position, the center line of the first mounting groove 3011 and the center line of the second mounting groove 3023 are coaxially aligned.

[0062] The first mounting groove 3011 and the second mounting groove 3023 are set to be coaxial at the center line in the locked position, so that the magnetic attraction effect between the first magnetic member 6 installed in the first mounting groove 3011 and the second magnetic member 7 installed in the second mounting groove 3023 is optimal.

[0063] See Figure 3 , Figure 5 , Figure 6 , Figure 7 In some optional embodiments, the separable component 302 further includes a main body 3024 and a cover component 3025 that is separably connected to the main body 3024. The hollow cavity 3021 is formed on the main body 3024. One of the upper and lower ends of the main body 3024 is provided with an opening 30241 that communicates with the hollow cavity 3021. The cover component 3025 is located at the opening 30241 and is used to close the opening 30241.

[0064] An opening 30241 is provided in the hollow cavity 3021 to facilitate the installation of components inside the hollow cavity 3021. A detachable cover component 3025 is also provided to enable the opening 30241 to be opened and closed, thus meeting the requirements for disassembly and maintenance.

[0065] See Figure 5 , Figure 6 In some alternative embodiments, the second magnetic member 7 is fixed to the cover member 3025.

[0066] The second magnetic 7 is placed on the cover member 3025, that is, the second mounting groove 3023 can be opened on the separable member 302. On the one hand, it can simplify the manufacturing process, and on the other hand, it can avoid opening too many holes on the separable member 302, thus avoiding weakening the structural strength of the separable member 302 itself, which is conducive to achieving the stability and reliability of the locking assembly 3.

[0067] See Figure 5 , Figure 6 In some optional embodiments, the cover member 3025 is provided with a hook 30251, and the side wall of the main body 3024 is provided with a groove 30242 that cooperates with the hook 30251, and the groove 30242 extends through the outside of the main body 3024.

[0068] Through the slot 30242 extending through the main body 3024 of the separable component 302, the hook 30251 can be pushed away from the slot 30242, thereby separating the hook 30251 from the slot 30242 and thus making the cover component 3025 detachable from the main body 3024 of the separable component 302. When installing the cover component 3025, it is only necessary to hook the hook 30251 into the slot 30242, which is convenient for disassembly and assembly.

[0069] See Figure 5 , Figure 6 In some optional embodiments, the cover member 3025 is provided with a limiting protrusion 30252, and the main body 3024 is provided with an abutting protrusion 30243 corresponding to the limiting protrusion 30252. The abutting protrusion 30243 can abut against the limiting protrusion 30252, and when the limiting protrusion 30252 contacts the abutting protrusion 30243, the hook 30251 can be engaged into the slot 30242.

[0070] The limiting protrusion 30252 and the abutting protrusion 30243 are provided to assist in the installation of the cover member 3025. When the limiting protrusion 30252 abuts against the abutting protrusion 30243, the hook 30251 can be guided to the position of the slot 30242, and the hook 30251 and the slot 30242 can be locked together and fixed.

[0071] See Figure 3 , Figure 6 , Figure 7 In some optional embodiments, the outer surface of the separable member 302 is provided with an anti-slip structure, which includes multiple raised and recessed textures 3026 provided on the separable member 302, the multiple raised and recessed textures 3026 being arranged in parallel at intervals, and / or, a groove 3027 is provided on one of the two opposite sides of the separable member 302.

[0072] By providing raised and recessed textures 3026 and / or grooves 3027, users can grip the separable component 302 during disassembly and assembly, facilitating disassembly.

[0073] See Figure 3 , Figure 6 In some optional embodiments, the cover member 3025 of the separable member 302 is also provided with anti-slip texture 30253 to facilitate the removal and placement of the cover member 3025 during disassembly and assembly.

[0074] See Figure 7 In some optional embodiments, the slide rail 4 has a T-shaped cross-section, and the front and rear ends of the slide rail 4 are provided with rounded chamfers 401.

[0075] The rounded chamfer 401 facilitates alignment between the guide rail and the slide 5, improving the ease of connection. On the other hand, it also avoids damage to the components and users caused by sharp corners.

[0076] In summary, the locking assembly 3 provided by this utility model uses a first magnetic attractor 6 and a second magnetic attractor 7 that attract each other. At the locking position, the first magnetic attractor 6 and the second magnetic attractor 7 attract each other to fix the separable component 302 to the fixed component 301, thereby achieving a stable connection. When disassembly is required, only force needs to be applied to make the second magnetic attractor 7 on the separable component 302 and the first magnetic attractor 6 on the fixed component 301 misalign with each other, so as to reduce the magnetic flux between the two and weaken the locking force, thereby achieving disassembly. The disassembly process will not cause wear to the locking structure, which significantly improves the service life of the locking assembly 3. In addition, it is easy to install and remove, simple to manufacture, and low in cost.

[0078] Combining existing technologies Figure 1 This embodiment discloses a telescopic fence, including a base 1 and a telescopic belt assembly 2. The telescopic belt assembly 2 includes a fixed part 201, a movable part 202, and any of the locking components 3 in Embodiment 1 above. The fixed part 201 is fixed to the upper end of the base 1, and the movable part 202 is fixedly connected to the separable member 302 of the locking component 3. The fixed member 301 in the locking component 3 is fixed to the base 1 and its fixed position is near the upper end of the base 1.

[0079] See 3-5. Figure 7 The base 1 includes a base and a column disposed on the base. The fixing component 301 can be fixed to the column by screws or rivets through the through hole 3012, and the position of the detachable component 302 is fixed near the upper end face of the column.

[0080] It is understood that the base 1 and the telescopic belt assembly 2 are prior art and not the invention of this application, and their structures will not be described in detail here.
