Description

Technical Field

[0001] This utility model relates to the field of distribution box technology, specifically a connection structure between a distribution box cabinet and a cable tray. Background Technology

[0002] Cable trays are metal frame structures used to support, fix, and protect cables and wires. They play a crucial role in power distribution systems. During electrical installation, the connection between the distribution box (cabinet) and the cable tray needs to be treated to protect the outer insulation layer of the wires and cables from being cut or thinned, thus avoiding leakage or short circuit accidents. There are usually two methods for connecting the distribution box and the cable tray. One method is that the supplier processes it on the top of the distribution box in one go. The other method is to make a connector for assembly. Both connection methods rely on bolts for fixing. Although this method ensures the firmness of the connection to a certain extent, the problems that follow are also obvious.

[0003] Traditional bolt fixing methods require precise hole alignment and a complex tightening process, which not only increases installation time and costs but also demands a high level of expertise from operators. The cumbersome nature of bolt fixing is particularly pronounced during emergency repairs or system upgrades, impacting work efficiency. Furthermore, due to the large number and close proximity of bolts, disassembly often requires multiple tools and is time-consuming. This not only increases maintenance costs but also carries the risk of equipment damage or safety hazards due to improper operation. Utility Model Content

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1

[0029] Please see Figure 1-7 In this embodiment of the utility model, a connection structure between a distribution box cabinet and a cable tray includes a connector 100. The connector 100 includes a rectangular frame 110. The bottom of the rectangular frame 110 is inserted into a rectangular groove on the top surface of the distribution box body 200. The top surface of the rectangular frame 110 has an insertion groove 111 that is inserted into the bottom of the cable tray body 300 and the pressure plate body 400. A base 120 is detachably fixed to the bottom surface of the rectangular frame 110. The top surface of the base 120 contacts the inner top surface of the distribution box body 200. Three of the side walls of the rectangular frame 110 are provided with... A limiting component 130 is provided, which includes a contact plate 131 located in the insertion slot 111. A round rod 132 is fixedly connected to the side wall of the contact plate 131. The other end of the round rod 132 extends through to the outside of the rectangular frame 110. A limiting block 133 is fixedly connected to the end of the round rod 132. A return spring 134 is sleeved on the outer wall of the round rod 132 outside the rectangular frame 110. A sliding slot 310 and a sliding slot 410 are respectively opened on the bottom side of the cable tray body 300 and the pressure plate body 400 corresponding to the position of the round rod 132.

[0030] Specifically, a rectangular slot is provided on the top surface of the distribution box body 200. During installation, the base 120 is first fixed to the inner top surface of the distribution box body 200, and then the bottom of the rectangular frame 110 is inserted into the rectangular slot on the top surface of the distribution box body 200. At the same time, the bottom surface of the rectangular frame 110 is fixed to the top surface of the base 120, so that the rectangular frame 110 is inserted and fixed in the rectangular slot. Two limiting components 130 are located on the two opposite side walls of the rectangular frame 110, and another limiting component 130 is located on the front side wall of the rectangular frame 110. Since a return spring 134 is sleeved on the outer surface of the round rod 132 outside the rectangular frame 110, and the two ends of the return spring 134 contact the side wall of the limiting block 133 and the outer wall of the rectangular frame 110 respectively, the round rod 132 will extend outward as much as possible without external force, so that the contact plate 131 is in contact with the insertion slot. On the inner wall of the outer side of the slot 111, press the limiting blocks 133 on both sides to make the contact plate 131 close to the inner wall of the slot 111. At this time, the two sliding slots 310 on the bottom side of the cable tray body 300 can be aligned with the two round rods 132 respectively, and the cable tray body 300 can be inserted into the slot 111 until the bottom of the cable tray body 300 contacts the inner bottom surface of the slot 111. Release the limiting blocks 133. Under the rebound force of the return spring 134, the contact plate 131 will move, thereby fixing the cable tray body 300 in the slot 111 with the side wall of the slot 111. The cover plate body 400 also follows the same operation method to make the sliding slot 410 cooperate with the round rod 132, so that the cable tray body 300 and the cover plate body 400 are both fixed to the top of the distribution box body 200 by the connector 100.

[0031] like Figure 4 and Figure 7 As shown, in this embodiment, four plug-in blocks 112 are symmetrically fixedly connected to the bottom surface of the rectangular frame 110. Buckles 113 are installed on both sides of the four plug-in blocks 112. Four snap-fit ​​grooves 121 are symmetrically opened through the top surface of the base 120. Mounting holes 122 are opened at the four corners of the top surface of the base 120.

[0032] In this embodiment, during installation, the base 120 is first installed from the inside, with its top surface aligned with the inner top surface of the distribution box body 200. The base 120 is then fixed to the inner top surface of the distribution box body 200 using bolts passing through the mounting holes 122. Next, the rectangular frame 110 is removed and installed from the outside. The bottom of the rectangular frame 110 is inserted into the rectangular groove on the top surface of the distribution box body 200. The four insertion blocks 112 on the bottom surface of the rectangular frame 110 correspond to the four snap-fit ​​slots 121 on the top surface of the base 120. When the insertion blocks 112 are inserted into the snap-fit ​​slots 121... When the buckle 113 is squeezed and retracts into the insertion block 112, when the bottom surface of the rectangular frame 110 is in contact with the top surface of the base 120, the bottom end of the insertion block 112 extends to the bottom of the base 120. The buckle 113, which is no longer squeezed, rebounds and extends outward, thereby locking the insertion block 112 inside the snap-fit ​​groove 121, so that the rectangular frame 110 is fixed to the top surface of the base 120. When disassembly is required, it is only necessary to pinch the two buckles 113 to retract them into the insertion block 112, so that the insertion block 112 can be pulled out from the snap-fit ​​groove 121, which facilitates the combination and disassembly of the two.

[0033] like Figure 5 and Figure 7 As shown, in this embodiment, the side wall of the contact plate 131, which is fixed with the round rod 132, is fixedly connected with several docking blocks 1311. The bottom sides of the cable tray body 300 and the cover plate body 400, which are corresponding to the docking blocks 1311, are respectively provided with several docking grooves 320 and several docking grooves 420.

[0034] In practice, after pressing the limiting block 133 to make the contact plate 131 adhere to the inner wall of the insertion groove 111, the cable tray body 300 and the cover plate body 400 are inserted into the insertion groove 111. When the limiting block 133 is released, the limiting block 133 will move outward. At this time, several mating blocks 1311 located at the position of the cover plate body 400 are engaged with several sliding slots 410, and several mating blocks 1311 located at the position of the cable tray body 300 are engaged with several mating slots 320, so that the bottom of the cable tray body 300 and the cover plate body 400 are better fixed in the insertion groove 111, enhancing stability.

[0035] Example 2

[0036] Based on Embodiment 1, in order to make it more convenient to connect the cable tray body 300 and the cover plate body 400.

[0037] like Figure 4 and Figure 6As shown, in this embodiment, the connector 100 further includes three fixing components 140, the positions of which correspond to the three limiting components 130 respectively. Each fixing component 140 includes an outer housing 141, the end of which is fixedly connected to the outer wall of the rectangular frame 110. A round rod 132 extends into the interior of the outer housing 141. A rack 142 is fixedly connected to the inner top surface of the outer housing 141. A groove 1411 is formed on the bottom surface of the outer housing 141, and a connecting rod 143 is slidably inserted into the groove 1411. The outer wall of the connecting rod 143... A connecting block 144 is slidably sleeved, the bottom surface of the connecting block 144 is in contact with the inner bottom surface of the outer cover 141, the side wall of the connecting block 144 is fixedly connected to the side wall of the limiting block 133, a toothed block 145 is fixedly connected to the top end of the connecting rod 143, the toothed block 145 meshes with the rack 142, a return spring 148 is sleeved on the outer wall of the connecting rod 143 between the toothed block 145 and the connecting block 144, and a fixing block 146 is fixedly connected to the end of the connecting rod 143 extending out of the bottom of the outer cover 141, and a pull ring 147 is fixedly connected to the bottom surface of the fixing block 146.

[0038] In practice, pulling down the pull ring 147 causes the connecting rod 143 to move the toothed block 145 downwards, and the toothed block 145 no longer engages with the rack 142. At this time, the connecting rod 143 can be slid along the slide groove 1411 to slide towards the rectangular frame 110. Since the connecting block 144 is fixedly connected to the limiting block 133, an operation similar to pressing the limiting block 133 is achieved. Then, releasing the pull ring 147 causes the toothed block 145 to move upwards under the rebound force of the return spring 148, engaging with the rack 142 again, so that the contact plate 131 is attached to the inner wall of the insertion groove 111. Furthermore, it eliminates the need for a manual pressing action, facilitating the subsequent insertion of the cable tray body 300 or the cover plate body 400 into the insertion slot 111. After the bottom of the cable tray body 300 or the cover plate body 400 is inserted into the insertion slot 111, the pull ring 147 is pulled down to move the toothed block 145 downward. Then, following the rebound of the return spring 134, the connecting rod 143 moves along the slide groove 1411, so that the contact plate 131 is tightly pressed against the inner wall of the cable tray body 300 or the cover plate body 400. After that, the pull ring 147 is released, allowing the toothed block 145 to re-engage with the rack 142, thus enhancing the stability of the connection.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0040] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
