Description

Technical Field

[0001] This utility model relates to the field of material rack technology, specifically a material rack locking and clamping device. Background Technology

[0002] In the field of industrial production and material storage, racks are important equipment for the orderly storage of various materials. Among them, cantilever racks are widely used for storing long and cylindrical materials due to their structural characteristics. They are widely used to place long or tubular materials such as plastic pipes and PVC pipes. Several horizontal cantilevers extend from both sides of the rack. These cantilevers can directly support long and narrow materials such as plastic pipes, metal profiles, and pipes. The two ends of the pipes rest on the corresponding cantilevers on both sides of the rack. Layered and classified storage is achieved through the support of the cantilevers, which saves space and facilitates the retrieval and management of materials.

[0003] However, in actual use, existing cantilever racks rely solely on their own weight and the friction of the cantilever surface to maintain their position when materials such as plastic pipes are placed on the cantilever, which is not stable enough. Especially for pipe materials, the materials are prone to sliding, shifting or even falling off the cantilever due to slight external collisions, equipment vibrations or storage angle deviations. At the same time, the structural fixing and clamping of some cantilever racks can easily damage the surface of plastic pipes. Utility Model Content

To a certain extent, this improves or solves the problem that existing cantilever material racks, when materials such as plastic pipes are placed on the cantilever, rely solely on their own weight and the friction of the cantilever surface to maintain their position, which is not stable enough. Especially for pipe materials, the materials are prone to slippage or even falling off the cantilever due to slight external collisions, equipment vibrations, or storage angle deviations.

There are two springs, which are respectively sleeved on the rear end surfaces of the two limiting rods, and their front and rear ends are fixedly connected to the rear surface of the clamping plate and the front surface of the rubber clamp, respectively.

[0009] In a preferred embodiment of this utility model, the locking mechanism includes a box body, a partition, a positioning component, and a linkage control component. The box body is disposed at the lower end inside the cantilever and is fixedly connected to the lower end of the moving block and slidably connected to the cantilever. The partition is fixedly connected to the rear end inside the box body. There are two positioning components, which are respectively disposed on the left and right sides inside the box body.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0026] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0027] Example 1

[0028] Reference Figure 1-5 This is the first embodiment of the present utility model, which provides a material rack locking and clamping device, including a frame 1 and a cantilever 2. The number of cantilever 2 is several, and they are evenly fixedly connected to the front and rear surfaces of the left and right ends of the frame 1. Each of the several cantilever 2 has a cavity inside. Each of the several cantilever 2 has a movable groove 3 on its lower surface, which extends into the interior of the cantilever 2. Each of the several cantilever 2 has a movable groove 4 on its upper surface, which extends into the interior of the cantilever 2. Each of the several cantilever 2 is provided with a locking and clamping device 5.

[0029] The locking clamping device 5 includes a clamping component 6 and a locking mechanism 7. The clamping component 6 is located at the upper end inside the cantilever 2, and the locking mechanism 7 is located at the lower end inside the cantilever 2.

[0030] Specifically, the material rack locking device achieves adaptive clamping and stable locking of long strip materials such as plastic pipes through the coordinated action of the clamping component 6 and the locking mechanism 7. This not only prevents the material from sliding or falling due to external forces, but also protects the material surface through flexible contact.

[0031] Furthermore, by pulling the button 744 to release the limit of the locking mechanism 7, the clamping assembly 6, under the action of the strength spring 63, drives the clamping plate 64 to approach the material, and with the help of the adaptive buffer 65, achieves flexible clamping. After releasing the button 744, the locking head 732 of the locking mechanism 7 is inserted into the slot 8 to fix the clamping position. Thus, through the linkage between the clamping assembly 6 and the locking mechanism 7, the stable clamping and locking of the material is completed.

[0032] Example 2

[0033] In the second embodiment of this utility model, the clamping assembly 6 includes a slide rod 61, a moving block 62, a strength spring 63, a clamping plate 64, and an adaptive buffer 65. There are two slide rods 61, both of which are located inside the upper end of the cantilever 2, and their front and rear ends are respectively fixedly connected to the inner walls of the front and rear sides of the cantilever 2. The moving block 62 is sleeved on the surface of the two slide rods 61 and is slidably connected to the slide rods 61. The upper end of the moving block 62 extends out of the cantilever 2 through the moving groove 4 and is slidably connected to the cantilever 2. There are two strength springs 63, which are respectively sleeved on the rear end surface of the two slide rods 61, and their front and rear ends are respectively fixedly connected to the rear side surface of the moving block 62 and the rear side inner wall of the cantilever 2. The clamping plate 64 is fixedly connected to the upper end of the moving block 62.

[0034] The adaptive buffer 65 includes a limiting rod 651, a rubber clamp 652, and a spring 653. There are two limiting rods 651, which are respectively set at the upper and lower ends of the rear side of the clamping plate 64. The front ends of the two limiting rods 651 pass through the clamping plate 64 and are slidably connected to the clamping plate 64. The rubber clamp 652 is fixedly connected to the rear end of the two limiting rods 651. There are two springs 653, which are respectively sleeved on the rear end surface of the two limiting rods 651, and their front and rear ends are fixedly connected to the rear surface of the clamping plate 64 and the front surface of the rubber clamp 652, respectively.

[0035] Specifically, by setting up the clamping component 6, the elastic tension of the strength spring 63 achieves automatic clamping of the pipe material. Combined with the flexible contact and elastic adjustment of the adaptive buffer 65, it can not only firmly clamp pipe materials of different diameters, but also avoid damage to the surface of the pipe material caused by rigid clamping. At the same time, the compression stroke of the spring 653 can accommodate the positioning error of the locking mechanism 7, thereby improving the adaptability and safety of the device.

[0036] Furthermore, after unlocking, the strength spring 63 pulls the moving block 62 backward along the two sliding rods 61. At the same time, the moving block 62 drives the clamping plate 64 to move backward synchronously, so that the clamping plate 64 gradually approaches the surface of the pipe, pulling the pipe backward to cooperate with the frame to clamp the pipe, thereby clamping and stabilizing the pipe. Meanwhile, when the rubber clamping plate 652 on the rear side of the clamping plate 64 contacts the pipe, the reaction force generated by the pipe on the rubber clamping plate 652 will push the two limit rods 651 to slide forward along the clamping plate 64. At this time, the spring 653 sleeved on the rear end of the limit rod 651 is compressed. The reaction force of the spring 653 will continue to push the rubber clamping plate 652, so that it fits tightly against the surface of the pipe. The flexible contact of the rubber prevents the pipe from being scratched. At the same time, the compression stroke of the spring 653 can adapt to the matching error between the clamping head 732 and the clamping groove 8.

[0037] Example 3

[0038] In the third embodiment of this utility model, the locking mechanism 7 includes a box 71, a partition 72, a positioning component 73, and a linkage control component 74. The box 71 is disposed at the lower end inside the cantilever 2 and is fixedly connected to the lower end of the moving block 62 and slidably connected to the cantilever 2. The partition 72 is fixedly connected to the rear end inside the box 71. There are two positioning components 73, which are respectively disposed on the left and right sides inside the box 71. The linkage control component 74 is disposed on the lower side in front of the two positioning components 73.

[0039] The positioning assembly 73 includes a positioning rod 731, a locking head 732, a push spring 733, a bending member 734, and an extrusion groove 735. There are two positioning rods 731, both of which are located on the right side of the rear end inside the box body 71, and their left and right ends are fixedly connected to the right side surface of the partition 72 and the right side inner wall of the box body 71, respectively. The locking head 732 is sleeved on the right end of the two positioning rods 731 and is slidably connected to the positioning rods 731. The right rear end of the locking head 732 extends out of the box body 71 and is slidably connected to the box body 71. There are two push springs 733, which are sleeved on the surfaces of the two positioning rods 731, and their left and right ends are fixedly connected to the right side surface of the partition 72 and the left side surface of the locking head 732, respectively. The bending member 734 is fixedly connected to the front surface of the locking head 732. The extrusion groove 735 is opened on the left side of the front end of the bending member 734.

[0040] Several slots 8 are evenly provided on the left and right sides of the lower inner surface of the cantilever 2. The slot heads 732 on the left and right sides extend out of the box body 71 and correspond to and fit the slots 8 on both sides respectively.

[0041] The linkage control component 74 includes a support rod 741, a movable plate 742, a pull rod 743, and a pull button 744. There are two support rods 741, which are respectively located on the left and right sides of the lower end of the box body 71, and their front and rear ends are respectively fixedly connected to the inner walls of the front and rear sides of the box body 71. The movable plate 742 is sleeved on the front end surface of the two support rods 741 and is slidably connected to the support rods 741. There are two pull rods 743, which are respectively fixedly connected to the left and right sides of the upper surface of the movable plate 742. The upper ends of the two pull rods 743 extend into the interior of the two extrusion grooves 735 and are movably connected to the extrusion grooves 735. The pull button 744 is fixedly connected to the lower end surface of the movable plate 742, and its lower end extends out of the box body 71 and extends to the cantilever 2 through the movable groove 3. The pull button 744 is movably connected to the box body 71 and the cantilever 2.

[0042] Specifically, by setting a locking mechanism 7, in which the linkage control component 74 and the positioning component 73 cooperate, the clamping component 6 can be quickly locked and unlocked. The setting of multiple slots 8 can adapt to the clamping requirements of pipes with different diameters. The continuous thrust of the push spring 733 ensures that the clamping head 732 and the slot 8 are stably engaged, improving the convenience of device operation and the reliability of clamping.

[0043] Furthermore, the two ends of the pipe are placed on the left and right cantilever arms 2 of the frame 1 respectively, and are located between the clamping plate 64 and the frame 1. Then, the clamping plate 64 is unlocked. By pulling the button 744 forward, the moving plate 742 is moved forward along the two support rods 741. At the same time as the moving plate 742 moves forward, the two pull rods 743 move forward inside the two extrusion grooves 735 to extrude the inner wall of the two extrusion grooves 735, so that the two bent parts 734 are subjected to inward extrusion force, which in turn drives the two clamping heads 732 to overcome the push force of the push spring 733, compress the push spring 733, and move into the box 71 on the surface of the positioning rod 731. When the two clamping heads 732 move into the box 71, they will gradually disengage from the corresponding clamping grooves 8 on both sides of the cantilever arm 2. At this time, the limiting effect of the locking mechanism 7 is released.

[0044] During clamping, the movement of the moving block 62 causes the lower box 71 to slide synchronously along the inside of the cantilever 2. When the tube is clamped to the appropriate position, the pull button 744 is released, the moving plate 742 loses the forward holding force, and the chuck 732 will move out of the box 71 along the positioning rod 731 under the pushing force of the push spring 733, and re-embed into the corresponding slot 8 to complete the locking. The moving plate 742 will reset backward along the support rod 741 under the reaction force of the push spring 733.

[0045] Working principle:

[0046] In use, place the two ends of the pipe on the left and right cantilever arms 2 of the frame 1 respectively, and position them between the clamping plate 64 and the frame 1. Then, release the lock of the clamping plate 64 by pulling the button 744 forward, which will drive the moving plate 742 to move forward along the two support rods 741. At the same time, the moving plate 742 will drive the two pull rods 743 to move forward inside the two extrusion grooves 735 to extrude the inner wall of the two extrusion grooves 735, so that the two bent parts 734 are subjected to inward extrusion force, which will drive the two clamps 732 to overcome the push force of the push spring 733, compress the push spring 733, and move into the box 71 on the surface of the positioning rod 731. When the two clamps 732 move into the box 71, they will gradually disengage from the corresponding clamping grooves 8 on both sides of the cantilever arm 2. At this time, the limiting effect of the locking mechanism 7 is released.

[0047] After unlocking, the tension spring 63 pulls the moving block 62 backward along the two sliding rods 61. Simultaneously, the moving block 62 drives the clamping plate 64 to move backward, gradually bringing it closer to the pipe surface and pulling the pipe backward to cooperate with the frame in clamping the pipe, thus securing it firmly. At the same time, when the rubber clamping plate 652 on the rear side of the clamping plate 64 contacts the pipe, the reaction force generated by the pipe on the rubber clamping plate 652 pushes the two limit rods 651 forward along the clamping plate 64. At this time, the spring 653 sleeved at the rear end of the limit rod 651 is compressed. The reaction force of the spring 653 continuously pushes the rubber clamping plate 652, ensuring it fits tightly against the pipe surface. The flexible contact of the rubber prevents scratches on the pipe, and the compression stroke of the spring 653 can accommodate the fitting error between the chuck 732 and the slot 8.

[0048] During this process, the movement of the moving block 62 causes the lower box 71 to slide synchronously along the inside of the cantilever 2. When the tube is clamped to the appropriate position, the pull button 744 is released, the moving plate 742 loses the forward pulling force, and the clamp 732 will move along the positioning rod 731 to the outside of the box 71 under the pushing force of the push spring 733, and re-embed into the corresponding slot 8 to complete the locking. The moving plate 742 will reset backward along the support rod 741 under the reaction force of the push spring 733.

[0049] In summary, by using the frame 1, cantilever 2, movable groove 3, moving groove 4, locking clamping device 5, clamping assembly 6, slide rod 61, moving block 62, strength tension spring 63, clamping plate 64, adaptive buffer 65, limit rod 651, rubber clamping plate 652, spring 653, locking mechanism 7, box 71, partition 72, positioning assembly 73, positioning rod 731, clamp head 732, push spring 733, bending part 734, extrusion groove 735, linkage control assembly 74, support rod 741, moving plate 742, pull rod 743, pull button 744, and clamping groove 8 in combination, the material is clamped stably, the clamping position is locked to prevent slippage and displacement, and the material surface is protected through flexible contact.
