Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and in particular to a connector for assembling a storage rack and a connecting process thereof. Background Art

[0002] There are many significant benefits to assembling shelves. Assembled shelves can effectively utilize space. Whether in the kitchen, bedroom or office, they can reasonably store various items, making the space neat and orderly, and improving space utilization. At the same time, assembled shelves are convenient and flexible, and can be adjusted and combined according to actual needs and space layout to meet a variety of usage scenarios. Connectors play a vital role in the assembly of shelves. High-quality and suitable connectors can ensure that the various components of the shelf are firmly connected, enhance the overall structural stability, and improve the load-bearing capacity of the shelf, so that it can safely place more items.

[0003] The existing modular display racks are assembled and spliced ​​by locking multiple bolts. After the connectors are fixed, the angles are fixed, which makes it inconvenient to adjust the assembled racks. If the connectors are loosened before adjustment, not only do you need to move the items on the racks first, but you also need to disassemble the connectors one by one. The operation is cumbersome and can easily cause deformation of the connectors. The racks are not tightly assembled and have a loose structure, which not only affects the appearance, but also affects the stability of the racks, causing the racks to easily fall apart during use and other dangerous situations. Summary of the invention

[0005] In view of the above-mentioned shortcomings of the prior art, the present invention provides a connecting piece for assembling a storage rack and a connecting process thereof, which can effectively solve the problem that the storage rack in the prior art cannot be adjusted in angle.

[0006] Technical Solution

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0008] The present invention provides a connecting piece for assembling a storage rack, comprising:

[0009] Storage board;

[0010] A connecting part, the connecting part includes a clamping piece that is clamped and connected with the side of the storage board, a positioning piece is arranged inside the clamping piece, a connector is arranged on the outer surface of the positioning piece, two clamping pieces are arranged and are symmetrically distributed up and down with the connector as the center, and one end of the positioning piece passes through the clamping piece and fits with the side of the storage board;

[0011] The connection relationship between the positioning member and the connector includes two types: rotation and engagement. The positioning member includes a nut that is easy for the staff to operate. By changing the angle of the nut, the connection relationship between the positioning member and the connector changes accordingly. At this time, the connector moves under the restriction of the engagement member to adjust the height or angle between the storage plates.

[0012] Wherein, a reinforcing plate for limiting the side of the storage plate is arranged inside the engaging member.

[0013] Furthermore, the engaging part includes an engaging frame that is engaged with the side of the storage plate, a limiting groove is provided on the side of the engaging frame, a support plate is slidably connected to the inner wall of the limiting groove, a connecting rod is hingedly connected to the bottom end of the support plate, a movable shaft is rotatably connected to the middle part of the connecting rod, and the other end of the connecting rod is in contact with the bottom end of the reinforcement plate.

[0014] Furthermore, the positioning member includes a snap fitter embedded in the limiting groove, a reinforcement block is threadedly connected to the side of the snap fitter, a limiting concave ring is arranged on the inner wall of the reinforcement block, the other end of the limiting concave ring is fixedly connected to a limiting rod, the outer wall of the limiting rod is movably connected to the inner wall of the connector, the other end of the limiting rod is fixedly connected to a screw, the other end of the screw is fixedly connected to a knob, the outer wall of the screw is threadedly connected to a nut, and the nut is fixedly connected to a blocking block on the side close to the limiting rod.

[0015] Furthermore, the clamp includes a fixed block threadedly connected to the inner wall of the reinforcement block, the other end of the fixed block is fixedly connected to a clamping block, the other end of the clamping block is fixedly connected to another fixed block, the other end of the fixed block is provided with a spiral screw, and the outer wall of the clamping block is provided with a rubber layer.

[0016] Furthermore, the connector includes a positioning ring slidably connected to the outer wall of the limiting rod, the side of the positioning ring is fixedly connected to a limiting convex ring, the bottom end of the positioning ring is fixedly connected to a support rod, and the bottom end of the support rod is fixedly connected to the top of another positioning ring.

[0017] Furthermore, a plurality of protrusions are provided on the side of the positioning ring, and the protrusions are engaged and connected with the grooves provided on the side of the limiting concave ring.

[0018] Furthermore, the diameter of the screw is smaller than the diameter of the limiting rod, and the size of the blocking block is larger than the diameter of the limiting rod.

[0019] A connection process for a connecting piece for assembling a storage rack comprises the following steps:

[0020] S1, assembly, firstly, place the engaging parts at appropriate positions on the side of the storage board according to the requirements, ensure that the engaging parts are evenly placed on the outside of the storage board, then combine multiple storage boards by installing connectors, and finally fix the engaging parts and connectors by installing nuts to achieve multi-level positioning of the storage boards, thus completing the assembly process of the storage rack;

[0021] S2. Release the fastening and rotate the nut in the opposite direction so that the block is no longer embedded in the positioning ring. The connector slides on the outer wall of the limit rod. The limit convex ring moves without limiting the limit concave ring. Then, rotate the knob in the opposite direction so that the card can slide on the inner wall of the limit groove. At this time, the fastening state of the storage plate and the connecting part is released. The staff applies force to the side of the storage plate as needed, so as to adjust the angle of the corresponding storage plate and change the distance between the storage plates.

[0022] S3. Re-tighten and rotate the knob so that the engaging part limits the side of the storage plate again, and then rotate the nut so that the connector is again limited by the blocking block and the limiting concave ring to ensure that the connector position is stable after the angle is changed.

[0023] Beneficial Effects

[0024] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects:

[0025] The present invention is provided with a connecting part, the connecting part is a clamping piece, a positioning piece and a connector, the positioning piece is embedded in the clamping piece, and the positioning piece and the clamping piece are in a sliding connection state before being installed;

[0026] The position of the clamping parts before assembly can be adjusted according to the different support requirements of the storage plate, because the gap existing in the position adjustment of the clamping parts will also be filled by the reinforcement plate, and the upper and lower ends of the side of the storage plate are limited by the reinforcement plate of the clamping parts. The clamping device rotates to adjust the position of the reinforcement plate and the spiral screw extends with the rotation, and the spiral screw limits the side of the storage plate. Therefore, the storage plate can be limited and fixed from three directions by the rotating clamping device, thereby enhancing the stability of the connection structure between the clamping parts and the storage plate. At the same time, the multi-stage limit design can increase the friction to prevent the nut from rotating, effectively improving the situation where the vibration in the external environment causes the fit between the nuts to become loose, affecting the stability of the entire structure.

[0027] When the storage plate needs to be adjusted, the nut is rotated in the opposite direction so that the block is no longer embedded in the positioning ring, the connector slides on the outer wall of the limit rod, the limit convex ring moves without limiting the limit concave ring, and then the knob is rotated in the opposite direction so that the latch can slide on the inner wall of the limit groove. At this time, the fastening state of the storage plate and the connecting part is released, and the staff applies force to the side of the storage plate as needed, so as to achieve the purpose of adjusting the angle of the corresponding storage plate and changing the distance between the storage plates.

DETAILED DESCRIPTION

[0038] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] The present invention will be further described below in conjunction with the embodiments.

[0040] Example:

[0041] See also Figure 1-Figure 7 The present invention provides a technical solution: a connecting piece for assembling a storage rack, comprising: a storage plate 2 and a connecting part 1, a plurality of connecting parts 1 are arranged on the side of the storage plate 2, and a plurality of storage plates 2 are assembled into a whole through the connecting part 1 to complete the assembly of the storage rack, reference Figure 2 Before assembly, the storage plate 2 of the device exists separately, and the connecting part 1 is divided into a snap-fitting part 11, a positioning part 12 and a connector 13. The snap-fitting part 11 and the positioning part 12 are in a connected state, and the positioning part 12 is embedded in the snap-fitting part 11. Before installation, the positioning part 12 and the snap-fitting part 11 are in a sliding connection state.

[0042] refer to Figure 2 , Figure 3 and Figure 4 The engaging member 11 is engaged and fixed with the side of the storage plate 2. The engaging member 11 includes an engaging frame 111 engaged with the side of the storage plate 2. A limiting groove 112 is provided on the side of the engaging frame 111. The limiting groove 112 is composed of two groove bodies of different sizes. The middle parts of the two groove bodies are rectangular in design, and the sides are arc-shaped. The large-sized groove body is located in the middle of the small-sized groove body. The inner wall of the large-sized groove body is slidably connected with a push plate 113. The engaging device 127 is embedded in the inner wall of the large-sized groove body. The vertical dimension of the engaging device 127 is larger than the horizontal dimension of the engaging device 127. The horizontal dimension of the engaging device 127 is slightly larger than the dimension of the small-sized groove body. The engaging device 127 before assembly is embedded in the middle part of the limiting groove 112 and can slide inside. The elastic supporting structure arranged on the other side of the push plate 113 can support the engaging device 127 in this state, and will not move vertically when not subjected to external force.

[0043] Reference 3 and Figure 6 The bottom of the plate 113 is hingedly connected with connecting rods 116 on both sides, the middle of the connecting rod 116 is rotatably connected with a movable shaft 115, and the top of the other end of the connecting rod 116 is hingedly connected with a round rod, which passes through the reinforcing plate 114, and the reinforcing plate 114 is symmetrically arranged in the middle of the inner wall of the snap-fit ​​frame 111;

[0044] refer to Figure 7The clamp 127 includes a fixed block 1271 threadedly connected to the inner wall of the reinforcement block 126, the other end of the fixed block 1271 is fixedly connected to a clamping block 1272, the other end of the clamping block 1272 is fixedly connected to another fixed block 1271, the other end of the fixed block 1271 is provided with a spiral screw 1274, and the outer wall of the clamping block 1272 is provided with a rubber layer 1273.

[0045] refer to Figure 2 , Figure 4 and Figure 7 The positioning member 12 includes a snap fitter 127 embedded in the limiting groove 112, a reinforcement block 126 is threadedly connected to the side of the snap fitter 127, a limiting recessed ring 125 is arranged on the inner wall of the reinforcement block 126, the other end of the limiting recessed ring 125 is fixedly connected to a limiting rod 124, the outer wall of the limiting rod 124 is movably connected to the inner wall of the connector 13, the other end of the limiting rod 124 is fixedly connected to a screw 122, the other end of the screw 122 is fixedly connected to a knob 123, the outer wall of the screw 122 is threadedly connected to a nut 121, and a blocking block 128 is fixedly connected to the side of the nut 121 close to the limiting rod 124.

[0046] In the initial state, nut 121 is not threadedly connected with screw rod 122, and the staff rotates knob 123, and the rotation of knob 123 drives screw rod 122 to rotate, and the rotation of screw 122 drives limiting rod 124 to rotate, and the rotation of limiting rod 124 drives limiting concave ring 125, reinforcement block 126 and clamp 127 to rotate synchronously as a whole, and the fixed block 1271 of clamp 127 rotates on the inner wall of the small-sized groove body of limiting groove 112, and the clamping block 1272 rotates on the inner wall of the large-sized groove body in the middle of limiting groove 112, and the fixed block 1271 assists the rotation movement of the clamping block 1272 to ensure the stability of the rotation process, and the clamping block 1272 rotates from a horizontal state to a vertical state, and the clamping block 1272 squeezes the back plate 113 after being vertical, and the back plate 113 overcomes the elastic force of the spring sheet at the other end and slides on the inner wall of the limiting groove 112, and the vertical movement of the back plate 113 drives The connecting rod 116 rotates around the movable shaft 115, and the other end of the connecting rod 116 applies an upward force to the round rod at the bottom end of the reinforcing plate 114. The reinforcing plate 114 moves upward under the force, and can fill the gap between the storage plate 2 and the locking frame 111. The reinforcing plates 114 symmetrically arranged above and below move relatively to pressurize the upper and lower ends of the side edges of the storage plate 2, thereby tightening and limiting the storage plate 2 and the locking piece 11 locked in the appropriate position of the storage plate 2. Before assembly, the area where the locking piece 11 is located will be confirmed according to the length of the plate to achieve the purpose of balanced support of the storage plate 2. The locking block 1272 rotates to drive the rubber layer 1273 to rotate. When the rubber layer 1273 rotates to a vertical state with the locking block 1272, the rubber layer 1273 is tightly fitted with the abutment plate 113, increasing the friction between the two, and ensuring the stable position of the locking block 1272 after rotation.

[0047] refer to Figure 2 and Figure 5 The connector 13 includes a positioning ring 132 that is slidably connected to the outer wall of the limiting rod 124, a limiting convex ring 133 is fixedly connected to the side of the positioning ring 132, and a support rod 131 is fixedly connected to the bottom end of the positioning ring 132. Two positioning rings 132 are provided and are symmetrically distributed up and down with the support rod 131 as the center. A plurality of protrusions are opened on the side of the limiting convex ring 133, and the protrusions are engaged with the grooves opened on the side of the limiting concave ring 125.

[0048] After the positioning of the side engaging piece 11 of a single storage plate 2 is completed, the connector 13 is installed on the side of the positioning piece 12 for connecting multiple storage plates 2 to complete the assembly operation. A groove is opened in the middle of the positioning ring 132, and the side of the groove away from the limiting convex ring 133 adopts an oblique groove design with a large outside and a small inside. The staff puts the positioning ring 132 on the outer wall of the limiting rod 124, and then puts the nut 121 on the outer wall of the screw rod 122. The nut 121 is rotated so that the nut 121 moves to the end of the screw rod 122 close to the limiting rod 124, and the nut 1 The blocking block 128 fixed on the side of 21 adopts an inclined surface setting that matches the inclined groove. At this time, the blocking block 128 is completely embedded in the inclined groove of the positioning ring 132, further increasing the contact area between the two, and realizing the primary limiting of the positioning member 12 on the connector 13. The nut 121 and the blocking block 128 push the positioning ring 132, so that the limiting convex ring 133 fixed on the side of the positioning ring 132 is engaged with the limiting concave ring 125. The engagement and fixation of the two also further enhances the fixing effect between the positioning member 12 and the connector 13.

[0049] Before assembly, the engaging member 11 can be adjusted in position according to different support requirements of the storage plate 2, because the gap existing in the adjustment will also be filled by the reinforcement plate 114, and the upper and lower ends of the side of the storage plate 2 are limited by the reinforcement plate 114 on the inner wall of the engaging member 11, and the engaging device 127 rotates to adjust the position of the reinforcement plate 114 while the spiral screw 1274 extends with the rotation, and the spiral screw 1274 limits the side of the storage plate 2, so that the rotating engaging device 127 can limit and fix the storage plate 2 from three directions, thereby improving the stability of the connection between the engaging member 11 and the storage plate 2, and at the same time, the multi-stage limiting design can increase the friction to prevent the nut 121 from rotating, and effectively improve the situation where the vibration in the external environment causes the fit between the nuts 121 to become loose, affecting the stability of the entire structure.

[0050] After the engaging member 11 is disassembled, the storage plate 2 will not be damaged. During the use of the storage plate 2, it may need to be reassembled due to space layout adjustment, function change, etc. The present invention can be easily disassembled and reassembled, so that the storage plate 2 can be reused many times, which greatly extends its service life, avoids the waste of raw materials caused by frequent replacement of the storage plate 2, and promotes the recycling of resources. When a part of the storage rack is damaged, such as the connection part 1 is aged or damaged, the connection process of the storage plate 2 will not be damaged. It is convenient to disassemble and replace the damaged part separately without replacing the entire storage rack, which reduces The maintenance cost is reduced. Since the disassembly process will not cause damage to the storage plate 2, there is no need to worry about damaging other intact parts when repairing or replacing parts, which reduces the risk and workload in the maintenance process. This not only saves labor costs, but also avoids more losses caused by improper maintenance, and improves maintenance efficiency. The non-destructive disassembly connection process ensures that after multiple disassemblies, the surface of the storage plate 2 will not leave scratches, breakages and other defects, maintaining its original beauty. After reassembly, the storage plate 2 can still be used safely and reliably, and there will be no loosening, deformation and other problems that affect the structural safety due to disassembly.

[0051] When the size and type of the items placed change, the original height and angle cannot be adapted and need to be adjusted to meet the storage needs. In the present invention, the connecting portion 1 itself has two states: fastened and movable. There is no need to first remove the items on the shelf and then completely disassemble and dismantle the shelf. The height or angle of the shelf can be changed without affecting the stability of the shelf.

[0052] By rotating the nut 121 in the opposite direction, the nut 121 drives the block 128 to move on the outer wall of the screw rod 122, and the block 128 moves from the end close to the limit rod 124 to the end away from the limit rod 124, and the block 128 is no longer embedded in the positioning ring 132, and the side of the connector 13 is not restricted. At this time, the connector 13 can slide on the outer wall of the limit rod 124, and the movable limit convex ring 133 no longer limits the limit concave ring 125. At this time, the other structures of the positioning member 12 fixedly connected to the limit concave ring 125 are not restricted. The staff then rotates the knob 123 in the opposite direction. The rotation of the knob 123 can drive the clamp 127 to rotate through the screw rod 122, the limit rod 124, the limit concave ring 125 and the reinforcement block 126. The clamp 127 slides on the inner wall of the limit groove 112, and the clamping block 1272 turns from vertical to horizontal. When the connecting member 12 is in the locked state, the locking member 124 is in the locked state, and the locking member 124 is in the locked state. ...

[0053] The movable and fastened states of the engaging member 11 of the present invention can be switched as needed, and the fastening structure will not be damaged after switching, which effectively solves the problem that when the angle of the storage rack is adjusted in the prior art, a small angle adjustment of the screw and nut 121 connecting member may cause it to bear additional shear force, resulting in thread wear, while a large angle change may cause the screw to bend or even break; the snap-on connector has a reduced fit between the snap-on and the slot when the angle is fine-tuned, and is prone to loosening; a large angle change is more likely to cause the snap-on to lose elasticity or even break due to excessive stretching or twisting; gaps may appear between the components of the angle code connector when the angle is adjusted at a small angle, resulting in uneven local force and increased wear, and a large angle change will cause it to twist and deform, and the connecting hole will be misplaced, seriously affecting the connection effect and the overall stability of the storage rack.

[0054] See also Figure 8 On the other hand, the present invention provides a connection process of a connection piece for assembling a storage rack, comprising the following steps:

[0055] S1, assembly, firstly, place the engaging member 11 at an appropriate position on the side of the storage board 2 according to the requirements, ensure that the engaging member 11 is evenly placed on the outside of the storage board 2, then combine multiple storage boards 2 by installing the connector 13, and finally fix the engaging member 11 and the connector 13 by installing the nut 121, so as to realize the multi-level limit of the storage board 2, and complete the assembly process of the storage rack;

[0056] S2, release the fastening, rotate the nut 121 in the opposite direction, so that the block 128 is no longer embedded in the positioning ring 132, and the connector 13 slides on the outer wall of the limiting rod 124, and the limiting convex ring 133 moves without limiting the limiting concave ring 125, and then the knob 123 is rotated in the opposite direction, so that the clamp 127 can slide on the inner wall of the limiting groove 112, and the fastening state of the storage plate 2 and the connecting part 1 is released at this time, and the staff applies a force to the side of the storage plate 2 as needed, so as to achieve the operation of adjusting the angle of the corresponding storage plate 2 and changing the distance between the storage plates 2;

[0057] S3, re-tighten, rotate the knob 123, so that the engaging member 11 limits the side of the storage plate 2 again, and then rotate the nut 121, so that the connector 13 is again limited by the blocking block 128 and the limiting concave ring 125, to ensure that the position of the connector 13 is stable after the angle is changed.

[0058] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
