Description

Technical Field

[0001] This utility model belongs to the field of cable tray technology, specifically relating to a quick connection structure for cable tray bends. Background Technology

[0002] Cable tray elbows are key connectors in cable tray systems used to achieve directional changes. They enable cable trays to turn flexibly in spatial layout, ensuring that cables are not damaged by right-angle bends during installation, while maintaining the neatness and aesthetics of the overall wiring. Types include horizontal elbows for horizontal turns, vertical elbows for vertical turns, and variable-diameter elbows to adapt to changes in cable tray width.

[0003] Patent application CN215733295U discloses an adjustable-angle cable tray connection elbow. In use, loosening bolt one from the fixing nut reduces the pressure between the left and right connecting cable trays, allowing the angle to be adjusted by rotating the left and right connecting cable trays as needed. While this cable tray connection elbow allows for angle adjustment of the left and right connecting cable trays, in actual use, the left and right connecting cable trays are connected by bolt one and the fixing nut. Connecting or disconnecting the left and right connecting cable trays requires external tools and takes a considerable amount of time, reducing work efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that external tools are required and time is consumed when connecting or disconnecting the left and right connecting cable trays, which reduces work efficiency. This invention provides a quick connection structure for cable tray bends.

[0005] The objective of this utility model can be achieved through the following technical solutions: A quick-connect structure for cable tray elbows includes an elbow body and a connecting cable tray. Symmetrically arranged positioning blocks are connected to the outer sides of the corresponding ends of the elbow body and the connecting cable tray. Each positioning block has a first mounting groove in its center, into which a first mounting block is inserted. A second mounting groove is formed in the center of the side of each first mounting block away from the positioning block. One set of first mounting blocks has an O-shaped first stop connected to the position inside the second mounting groove, while another set of first mounting blocks has a U-shaped second stop connected to the upper position inside the second mounting groove. A second mounting block is inserted into the second mounting groove, corresponding to both the first and second stops. A second elastic plate is connected to the side of the second mounting block closest to the first stop, and a third elastic plate is connected to the upper part of the side of the second mounting block closest to the second stop.

[0006] Preferably, the position of the second elastic plate away from the second mounting block is in contact with the first mounting block, and the position of the second elastic plate close to the second mounting block is in contact with the first stop block.

[0007] Preferably, the third elastic plate is attached to the first mounting block at a position away from the second mounting block, and the third elastic plate is attached to the second stop block at a position close to the second mounting block.

[0008] Preferably, the lengths of the second elastic plate and the second mounting plate are the same as the internal length of the first stop, the length of the third elastic plate is the same as the internal length of the second stop, and the length of the first stop is twice the length of the second stop.

[0009] Preferably, the first mounting groove is connected with symmetrically arranged extrusion blocks, and the first mounting block has symmetrically arranged grooves at the positions corresponding to the extrusion blocks, and the grooves are inserted into the first mounting block.

[0010] Preferably, a clamping block is connected to the middle of the side of the first mounting block near the elbow body, and the side of the clamping block away from the first mounting block is in contact with the positioning block.

[0011] Preferably, a first elastic plate is symmetrically arranged on the outer side of the pressing block, corresponding to the position of the extrusion stop block, and the first elastic plate is in contact with the extrusion stop block.

[0012] Preferably, an outer shell is connected to the upper surface of the elbow body at the position corresponding to the connection of the cable tray, a pressure plate is slidably connected inside the outer shell, a plurality of evenly arranged springs are connected between the pressure plate and the outer shell, and a lever is connected to the upper surface of the pressure plate.

[0013] The beneficial effects of this utility model are: 1) Insert the first mounting blocks into the first mounting slots. With the cooperation of the compression baffle and the first elastic plate, the first mounting blocks are fixed in the first mounting slots. After the first mounting blocks are fixed, send the second elastic plate into the second mounting slot. With the cooperation of the second elastic plate and the first stop, the second mounting blocks and the second elastic plate are fixed in the second mounting slot. After the second elastic plate and the second mounting blocks are fixed, align the third elastic plate with the second mounting slot and send it in. With the cooperation of the third elastic plate and the second stop, the second mounting blocks and the third elastic plate are fixed in the second mounting slot. When it is necessary to remove the elbow body or the connecting cable tray, lift the connecting cable tray upward or press down the elbow body to move the second stop upward away from the third elastic plate or move the third elastic plate downward away from the second stop, so that the third elastic plate is no longer obstructed. After the third elastic plate is no longer fixed, the elbow body moves away from the connecting cable tray or the connecting cable tray moves away from the elbow body, so that the elbow body and the connecting cable tray can be separated. This makes it more convenient and faster to connect or remove the elbow body and the connecting cable tray, thus improving work efficiency.

[0014] 2) The pressure plate presses the connecting cable tray to prevent the third elastic plate from moving out of the second mounting slot. When it is necessary to remove the elbow body or connecting cable tray, the pressure plate is pushed into the housing by pulling the lever. During the process of the pressure plate entering the housing, the spring is squeezed. The spring will contract and store the restoring force when squeezed. After the pressure plate enters the housing, it will not block the connecting cable tray, so the elbow body or connecting cable tray can be removed. After removal, the lever is released, and the pressure plate returns to its original position under the action of the spring's restoring force. After the connecting cable tray is reinstalled, it can block the connecting cable tray again, thus achieving the purpose of preventing it from falling off. Attached Figure Description

[0018] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0019] Please see Figure 1 - Figure 6As shown, a quick connection structure for a cable tray bend includes a bend body 1 and a connecting cable tray 11. A symmetrically arranged positioning block 2 is connected to the outer side of one corresponding end of the bend body 1 and the connecting cable tray 11. The positioning block 2 is used to assist in connecting the bend body 1 and the connecting cable tray 11.

[0020] Each positioning block 2 has a first mounting groove 21 in the middle, which is used to accommodate the extrusion block 212.

[0021] The first mounting groove 21 is connected to symmetrically arranged compression blocks 212, which are used to compress and block the first elastic plate 215.

[0022] A first mounting block 211 is inserted into the first mounting slot 21. The first mounting block 211 is used to store and fix the second elastic plate 224.

[0023] The first mounting block 211 has symmetrically arranged grooves 213 at the position corresponding to the pressing block 212. The grooves 213 are inserted into the first mounting block 211. By opening the grooves 213, it is ensured that the first mounting block 211 can be inserted into the first mounting groove 21.

[0024] A clamping block 214 is connected to the middle of the side of the first mounting block 211 near the elbow body 1. The side of the clamping block 214 away from the first mounting block 211 is in contact with the positioning block 2. Through the cooperation of the clamping block 214, the first mounting block 211 is prevented from sliding freely in the first mounting groove 21 after it is fixed.

[0025] A first elastic plate 215 is symmetrically arranged on the outer side of the pressing block 214 corresponding to the position of the pressing block 212. The first elastic plate 215 contacts the pressing block 212. Through the cooperation between the first elastic plate 215 and the pressing block 212, the first mounting block 211 can be fixed in the first mounting groove 21.

[0026] The first mounting block 211 has a second mounting groove 22 in the middle of the side away from the positioning block 2. The second mounting groove 22 is used to accommodate the second mounting block 223 and the second elastic plate 224 or the third elastic plate 225.

[0027] One set of first mounting blocks 211 is connected to an O-shaped first stop block 221 at a position inside the second mounting groove 22. The first stop block 221 is used to block the second elastic plate 224.

[0028] Another set of first mounting blocks 211 are connected to a U-shaped second stop 222 at the position above the inside of the second mounting groove 22. The second stop 222 is used to block the third elastic plate 225.

[0029] A second mounting block 223 is inserted into the second mounting slot 22, and the second mounting block 223 corresponds to the first stop block 221 and the second stop block 222. The second mounting block 223 is used to determine the installation position of the second elastic plate 224 and the third elastic plate 225.

[0030] A second elastic plate 224 is connected to the side of the second mounting block 223 near the first stop block 221. The position of the second elastic plate 224 away from the second mounting block 223 is in contact with the first mounting block 211, and the position of the second elastic plate 224 near the second mounting block 223 is in contact with the first stop block 221. This arrangement ensures that the second elastic plate 224 will not move freely in the second mounting groove 22 after installation.

[0031] A third elastic plate 225 is connected above the second mounting block 223 on the side near the second stop block 222. The third elastic plate 225 is in contact with the first mounting block 211 at the position away from the second mounting block 223, and in contact with the second stop block 222 at the position near the second mounting block 223. This arrangement ensures that the third elastic plate 225 will not move freely in the second mounting groove 22 after installation.

[0032] The lengths of the second elastic plate 224 and the second mounting plate are the same as the internal length of the first stop 221. The length of the third elastic plate 225 is the same as the internal length of the second stop 222. The length of the first stop 221 is twice the length of the second stop 222. This arrangement ensures that the third elastic plate 225 can be removed from the second mounting slot 22.

[0033] In practical use, the first mounting block 211 is inserted into the first mounting groove 21. During the insertion process, the compression baffle compresses the first elastic plate 215, causing the first elastic plate 215 to move inward. After the first mounting block 211 is fully inserted into the first mounting groove 21, the pressing block 214 will fit with the positioning block 2, preventing the first mounting block 211 from continuing to enter the first mounting groove 21. At this time, the first elastic block passes the compression baffle and is no longer compressed by the compression baffle, allowing the first elastic block to reset, extend, and fit with the compression baffle, thereby fixing the first mounting block 211 in the first mounting groove 21. After the first mounting block 211 is fixed, the second elastic plate 224 is sent into the second mounting groove 22. During the sending process, the first stop 221 squeezes the second elastic plate 224, causing the second elastic plate 224 to move inward. After the second elastic plate 224 is fully inserted into the second mounting groove 22, the second elastic plate 224 will be in contact with the first mounting block 211. At this time, the second elastic plate 224 passes the first stop 221 and is no longer squeezed by the first stop 221, so that the second elastic plate 224 returns to its original position, extends and is in contact with the first stop 221, thereby fixing the second mounting block 223 and the second elastic plate 224 in the second mounting groove 22. After the second elastic plate 224 is fixed to the second mounting block 223, the connecting cable tray 11 is moved closer to the elbow body 1 or the elbow body 1 is moved closer to the connecting cable tray 11. During the movement, the third elastic plate 225 is aligned with the second mounting groove 22 and sent in. During the sending process, the second stop block 222 squeezes the third elastic plate 225, causing the third elastic plate 225 to move inward. After the third elastic plate 225 is completely inserted into the second mounting groove 22, the third elastic plate 225 will fit with the first mounting block 211. At this time, the third elastic plate 225 passes the second stop block 222 and is no longer squeezed by the second stop block 222. The third elastic plate 225 is reset and extended and fits with the second stop block 222, thereby fixing the second mounting block 223 and the third elastic plate 225 in the second mounting groove 22. When it is necessary to remove the elbow body 1 or the connecting cable tray 11, lift the connecting cable tray 11 upward or press down the elbow body 1, so that the second stop 222 moves upward away from the third elastic plate 225 or the third elastic plate 225 moves downward away from the second stop 222, thereby removing the obstruction of the third elastic plate 225. After the third elastic plate 225 is no longer fixed, the elbow body 1 moves away from the connecting cable tray 11 or the connecting cable tray 11 moves away from the elbow body 1, so that the elbow body 1 and the connecting cable tray 11 can be separated. This makes it more convenient and faster to connect the elbow body 1 and the connecting cable tray 11 or to remove the elbow body 1 and the connecting cable tray 11, thus improving work efficiency.

[0034] The upper surface of the elbow body 1 is connected to the outer shell 3 at the position corresponding to the connection of the cable tray 11. The outer shell 3 is used to store the pressure plate 31.

[0035] A pressure plate 31 is slidably connected inside the housing 3, and the pressure plate 31 is in contact with the upper surface of the connecting bridge 11. The pressure plate 31 is used to block the connecting bridge 11 and prevent the third elastic plate 225 from disengaging from the second mounting groove 22.

[0036] A plurality of evenly arranged springs 32 are connected between the pressure plate 31 and the outer casing 3. The springs 32 are used to reset the pressure plate 31.

[0037] A lever 33 is connected to the upper surface of the pressure plate 31. The lever 33 is used to bring the pressure plate 31 into the housing 3.

[0038] The outer casing 3 has a movable groove 34 at the position corresponding to the toggle block 33. The toggle block 33 is slidably connected in the movable groove 34, which provides the necessary space for the toggle block 33 to move.

[0039] In practical use, the pressure plate 31 presses the connecting cable tray 11 to prevent the third elastic plate 225 from moving out of the second mounting slot 22. When it is necessary to remove the elbow body 1 or the connecting cable tray 11, the pressure plate 31 is pushed into the housing 3 by pulling the lever 33. During the process of the pressure plate 31 entering the housing 3, it will compress the spring 32. The spring 32 will contract and store the restoring force when it is compressed. After the pressure plate 31 enters the housing 3, it will not block the connecting cable tray 11, and the elbow body 1 or the connecting cable tray 11 can be removed. After the removal is completed, the lever 33 is released, and the pressure plate 31 returns to its original position under the action of the restoring force of the spring 32. After the connecting cable tray 11 is reinstalled, it can block the connecting cable tray 11 again, which achieves the purpose of preventing it from falling off.
