Technical Field

[0001] This utility model relates to the field of elevator technology, and in particular to a flexibly openable vertical waterproof box for installing circuit boards on the inner wall of an elevator shaft. Background Technology

[0002] The PCB boards installed on the inner walls of the elevator shaft require protective housings. Currently, sheet metal housings are mainly used for fixing and protection, but they have the following disadvantages:

[0003] (1) The sheet metal housing is assembled by fixing the sheet metal panel and the sheet metal housing with screws. After the installation is completed, when it is necessary to connect the well cable and subsequent maintenance, it is necessary to use tools such as screwdrivers to remove the panel for wiring, which wastes time and poses a risk that the screws may be lost or fall into the well, which has a negative impact on the efficiency of engineering installation and product quality.

[0004] (2) The sheet metal housing is not waterproof, and there is a risk of water damage to the PCB board when it is installed on the inner wall of the well.

[0005] Therefore, a mounting box that can be opened flexibly and has good waterproof performance is needed to fix the PCB board to the wall inside the elevator shaft. Utility Model Content

[0006] The purpose of this utility model is to provide a vertically mounted waterproof box that can be flexibly opened and closed. The cover can be slid open and closed flexibly, which facilitates on-site wiring and maintenance. It optimizes the installation and wiring process, and can protect against water intrusion into the well after vertical installation. It effectively solves the problems of conventional sheet metal shells being non-waterproof and the complex installation process of their panels and the easy loss of fixing screws.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A flexibly openable vertical waterproof box includes a box body for mounting a PCB board. The box body includes a bottom shell with an assembly cavity and a top cover that slides and snaps onto the opening of the assembly cavity. The bottom shell has slots distributed vertically along the box body on both sides. The slots have snap-fit ​​parts for fixing the top cover.

[0009] Furthermore, the lower, left, and right ends of the face cover are provided with waterproof baffles that protrude toward the bottom shell, and the upper end of the bottom shell is provided with a protruding waterproof cover plate for covering the upper end of the face cover.

[0010] Furthermore, the waterproof cover plate is provided with a first water-blocking edge that protrudes downward, and the upper end of the cover is provided with a second water-blocking edge that protrudes upward and extends to the inside of the first water-blocking edge.

[0011] Furthermore, the card slot is connected to the back of the bottom shell, and the lower end of the card slot is provided with a guide slope that is inclined towards the back of the bottom shell.

[0012] Furthermore, the surface of the cover away from the bottom shell is provided with guide marks for indicating the direction of sliding installation and an anti-slip textured structure for easy pushing.

[0013] Furthermore, the bottom of the box body has a cable outlet that communicates with the assembly cavity, and the cable outlet is provided with a cable tie for fixing the wire.

[0014] Furthermore, the assembly cavity is provided with at least one threaded hole for fixing the PCB board, and the PCB board is provided with a first through hole corresponding to the position of the threaded hole, and a screw is connected between the threaded hole and the first through hole.

[0015] Furthermore, the side wall of the assembly cavity is provided with a limiting block that engages with the edge of the PCB board.

[0016] Furthermore, the first through hole is located at the lower end of the PCB board, the limiting block is located on the top side wall of the assembly cavity, and the limiting block is engaged with the upper edge of the PCB board.

[0017] Furthermore, the top of the bottom shell is provided with an upwardly protruding mounting plate, and the mounting plate has at least one second through hole.

[0018] Compared with the prior art, this utility model provides a vertically mounted waterproof box that can be flexibly opened, which has the following advantages:

[0019] (1) The face cover can be quickly opened or closed by pressing and sliding it up and down, which simplifies the disassembly and assembly process of the face cover, facilitates wiring inside the box, and can protect against water intrusion in the well after vertical installation; at the same time, the face cover does not need to be fixed with screws, which solves the risk of screws falling off.

[0020] (2) By setting some limit blocks and using the buckle method, it is easy to quickly align and install the PCB board, and also to position and snap the PCB board, thereby simplifying the installation and fixing process of the circuit board.

[0030] The technical solution of this utility model will be clearly and completely described below through detailed embodiments and in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. 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.

[0031] Please refer to Figures 1-6This embodiment provides a flexibly openable vertical waterproof box, including a box body 1 for mounting a PCB board 2. Specifically, the box body 1 includes a bottom shell 11 with an assembly cavity 111 and a face cover 12 that slides and snaps onto the opening of the assembly cavity 111. The bottom shell 11 has slots 112 vertically distributed along both sides of the box body 1. Each slot 112 has a locking part 113 for fixing the face cover 12. The face cover 12 has fixing parts 121 on both sides that correspond to and engage with the locking parts 113 in the slots 112 on the same side. The face cover 12 can be quickly opened or closed by pressing and sliding it up and down, simplifying the assembly and disassembly process, facilitating wiring inside the box, and eliminating the risk of screw loss as the face cover 12 does not require screw fixation.

[0032] In some embodiments, for example, the bottom shell 11 and the top cover 12 constituting the box body 1 are both made of ABS plastic, with a flame retardant rating of V0. Specifically, such as... Figure 3 and Figure 5 As shown, the snap-fit ​​portion 113 is a protruding plate with a raised edge to enhance the snap-fit ​​locking capability of the faceplate 12; the fixing portion 121 is a protruding plate. During installation, by pressing the faceplate 12 and pushing it upward to slide it, the fixing portion 121 on the faceplate 12 can pass over the raised edge and embed into the slot 112, and be snap-fitted and fixed with the snap-fit ​​portion 113.

[0033] In some implementations, reference Figures 3-5 The assembly cavity 111 is provided with at least one threaded hole 117 for fixing the PCB board 2. The PCB board 2 has a first through hole 21 corresponding to the position of the threaded hole 117. A screw 3 is connected between the threaded hole 117 and the first through hole 21. As an example, the screw 3 is a self-tapping screw with a diameter of 3mm and a length of 10mm. The PCB board 2 is installed and fixed on the housing 1 by tightening the screw.

[0034] like Figure 3 and Figure 4 As shown, in order to protect the PCB board 2 and provide a better positioning effect, the side wall of the assembly cavity 111 is provided with a limiting block 118 that engages with the edge of the PCB board 2. By setting some limiting blocks 118, the PCB board 2 can be quickly aligned and installed using a snap-fit ​​method, and the PCB board 2 can also be positioned and engaged, thus simplifying the installation and fixing process of the circuit board.

[0035] As an example, such as Figure 3 and Figure 4As shown, the first through hole 21 is located at the lower end of the PCB board 2, and the limiting block 118 is located on the top side wall of the assembly cavity 111, and the limiting block 118 is engaged with the upper edge of the PCB board 2. Thus, when installing the PCB board 2, the upper end of the PCB board 2 can be engaged with the limiting block 118 first, and then the PCB board 2 can be pushed toward the bottom shell 11 so that the first through hole 21 on the PCB board 2 is aligned with the threaded hole 117 on the bottom shell 11. Finally, the PCB board 2 is locked and fixed in the assembly cavity 111 using screws 3.

[0036] As a preferred embodiment, refer to Figures 3-5 The limit block 118, threaded hole 117, first through hole 21, and screw 3 are all provided in twos, which are symmetrically distributed on the left and right sides, so as to balance the force distribution and have a better installation and fixing effect.

[0037] In some implementations, reference Figures 1-6 To improve the waterproofing effect after vertical installation, the lower, left, and right ends of the faceplate 12 are provided with waterproof baffles 122 that protrude towards the bottom shell 11, and the upper end of the bottom shell 11 is provided with waterproof cover plates 114 that protrude to cover the upper end of the faceplate 12. By adopting an integrated waterproof design at the upper end of the bottom shell 11, the upper end of the faceplate 12 after installation can be covered, achieving top waterproofing; furthermore, after the faceplate 12 is slidably fastened and fixed, the waterproof baffles 122 and waterproof cover plates 114 can also be used together to cover the installation gap between the faceplate 12 and the bottom shell 11, greatly improving the waterproofing effect.

[0038] As an improved implementation method, refer to Figures 1-6 The waterproof cover 114 has a first water-retaining edge 115 extending downwards, and the upper end of the cover 12 has a second water-retaining edge 123 extending upwards to the inner side of the first water-retaining edge 115. Thus, by utilizing the staggered distribution of the first water-retaining edge 115 and the second water-retaining edge 123, the waterproofing effect can be further improved after the entire structure is vertically fixed. As an example, the height of the first water-retaining edge 115 is 3mm.

[0039] In some specific implementation methods, such as Figure 5 As shown, the slot 112 is connected to the back of the bottom shell 11, and the lower end of the slot 112 is provided with a guide slope 116 that is inclined towards the back of the bottom shell 11. By designing a slope structure on both sides of the bottom shell 11 to facilitate drainage, water can be discharged along the guide slope 116 when it enters from the side.

[0040] In some implementations, reference Figures 1-6 The surface of the cover 12 away from the bottom shell 11 is provided with a guide mark 124 for indicating the direction of sliding installation and an anti-slip texture 125 for easy pushing. As an example, the anti-slip texture 125 may be a spaced-out groove structure.

[0041] In some implementations, reference Figure 2 and Figure 3 The bottom of the housing 1 has a cable outlet 13 that communicates with the assembly cavity 111. The cable outlet 13 is equipped with a cable tie 131 for fixing the wires. In this way, the well cable after being connected to the PCB board 2 can be led out through the cable outlet 13. The cable outlet 13 is located at the bottom of the housing 1, which reduces the risk of water ingress. Even if the housing 1 is exposed to water, it can be quickly drained from the cable outlet 13.

[0042] In some implementations, reference Figure 1 and Figure 5 The top of the bottom shell 11 is also provided with an upwardly protruding mounting plate 14, which has at least one second through hole 141. This mounting plate 14 facilitates quick and easy installation of the entire assembly on the inner wall of the elevator shaft. As an example, the mounting plate 14 has two second through holes 141.

Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.

[0044] 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.
