Description

Technical Field

[0001] This utility model relates to the field of junction boxes, and more specifically, to a waterproof and sealed platform scale junction box. Background Technology

[0002] With the development of technology, electronic platform scales that can directly display the weight of objects have emerged. The principle is to use pressure sensors and microprocessor modules to convert signals, thereby directly displaying the weight of the object on the display. The above electronic platform scales only require the manual placement of the object to be weighed on the weighing platform, which is quite convenient to operate. However, when the platform scale is used outdoors, it needs to be connected to the circuit, so a junction box is required.

[0003] A search revealed that Chinese patent CN220325221U discloses a "sealed and waterproof junction box," comprising a base and a cover. The base has a hollowed-out central cavity. One side wall of the base has a plug-in end communicating with the cavity. The plug-in end has a through-hole leading to the cavity. The plug-in end has a threaded portion near the base and an elastic portion away from the base. The threaded portion is an external thread, and the elastic portion consists of several elastic strips evenly arranged along a circular trajectory. The plug-in end and the base are an integral structure. This integral structure increases overall waterproof sealing. Furthermore, the improved structure enhances local sealing by increasing connection tightness. The refined design also optimizes local structures, significantly improving practicality and economy. However, the following drawbacks still exist:

[0004] (1) Although the existing junction box has increased the overall waterproof effect of the box through the integrated structure, the connection port of the existing junction box is an open structure. When used outdoors, water stains will flow into the interior through the connection port, which will still cause water seepage and damage.

[0005] (2) Although the existing junction box has a long interface structure for the wiring port, the extended part can block some water stains, but it does not have a completely shielded structure. Water stains will still flow into the wiring port when splashed horizontally, causing damage to the junction box.

[0006] Therefore, we made improvements and proposed a waterproof and sealed platform scale junction box. Utility Model Content

[0007] The purpose of this utility model is to address the following issues with existing junction boxes: although the integrated structure increases the overall waterproof effect of the box, the existing junction boxes have an open structure for the wiring ports. When used outdoors, water stains can flow into the interior through the wiring ports, causing water seepage and damage. Also, although the existing junction boxes have a long interface structure for the wiring ports, the extended part can block some water stains, but it does not have a completely shielding structure. Water stains can still splash horizontally and flow into the wiring ports, causing damage to the junction box.

[0008] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0009] A waterproof and sealed platform scale junction box is provided to improve the above-mentioned problems.

[0010] The present invention is as follows:

[0011] The device includes a box body, with wiring ports provided on the front and both sides of the box body. Lifting components are provided on the outer walls of the box body on both sides of the wiring ports, and insertion components are provided on the outer side of the lifting components away from the box body.

[0012] The lifting assembly includes side plates on the outer surface of the box at both sides of the wiring port, and a sliding groove is provided inside the side plate, and a sliding plate is movably disposed inside the sliding groove;

[0013] The insert assembly includes a support plate that is fitted between the front ends of the slide plates, a groove is provided on the lower surface of the support plate, and a vertical plate is fixedly installed on the upper surface of the support plate.

[0014] As a preferred technical solution of this utility model, the side wall of the slide groove is provided with a side groove, and the side wall of the slide plate is provided with a side plate that cooperates with the side groove.

[0015] As a preferred technical solution of this utility model, a first telescopic rod is provided on the vertical upper surface of the skateboard, and a first spring is fitted on the outer wall of the first telescopic rod.

[0016] As a preferred technical solution of this utility model, a through groove is provided in the center of the upright plate, and a plug that cooperates with the wiring port is movably arranged inside the through groove. A sealing ring is fitted on the outer wall of the rear end of the plug.

[0017] As a preferred technical solution of this utility model, a limiting groove is provided on the side wall of the through groove, and a limiting plate that cooperates with the limiting groove is provided on the side wall of the insertion post.

[0018] As a preferred technical solution of this utility model, a second telescopic rod is provided on the surface of the limiting plate away from the wiring port, and a second spring is fitted on the outer wall of the second telescopic rod.

[0019] As a preferred technical solution of this utility model, a pull plate is installed on the outer wall of the front end of the insertion post.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] In the solution of this utility model:

[0022] 1. By setting up side plates, sliding plates, side plates, a first telescopic rod, and a first spring, when wiring is required for the platform scale, the sliding plate is pulled upward to move it up in the sliding groove. With the side plates embedded in the side grooves, the stable upward movement of the sliding plate compresses the first telescopic rod and the first spring, causing them to contract. At this time, the insertion assembly is moved upward to the position above the wiring port, opening the wiring port. When wiring is not required, the upward pull on the sliding plate is released, and the first telescopic rod and the first spring push the sliding plate downward. With the side plates embedded in the side grooves, the sliding plate moves down stably, aligning the insertion post with the wiring port so that the insertion post can be stably inserted into the wiring port, achieving a waterproof sealing effect for the wiring port.

[0023] 2. By setting up a support plate, a retaining groove, a plug, a limiting plate, a second telescopic rod, and a second spring, when the wiring port needs to be opened, pull the pull plate forward, causing the plug to slide away from the wiring port in the through groove. This causes the limiting plate to slide in the limiting groove, compressing and contracting the second telescopic rod and the second spring. Pulling the slide plate upward moves the support plate up to the upper side of the wiring port, allowing the wiring head to be inserted into the wiring port. Under the downward pushing effect of the first telescopic rod and the first spring, the retaining groove is tightly attached to the wiring port and the upper side of the wiring, preventing water stains from flowing into the gap between the wiring port and the wiring, thus improving the waterproof effect. When the wiring is not needed, pull out the wiring. The first telescopic rod and the first spring push the slide plate downward to align the plug with the wiring port. Releasing the pull plate releases the tension, and the second telescopic rod and the second spring push the limiting plate backward, causing the plug to insert into the aligned through groove. The sealing ring is tightly attached to the wiring port end, improving the sealing and waterproof effect. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0032] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0033] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0034] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0035] like Figure 1-5 As shown, this embodiment proposes a waterproof and sealed platform scale junction box, including a box body 1. The box body 1 is provided with wiring ports 2 on the front and both sides. Lifting components are provided on the outer wall of the box body 1 on both sides of the wiring ports 2. Insertion components are provided on the side of the lifting components away from the box body 1.

[0036] The lifting assembly includes side plates 301 disposed on the outer surface of the box 1 on both sides of the wiring port 2. A sliding groove 302 is provided inside the side plate 301, and a sliding plate 303 is movably disposed inside the sliding groove 302.

[0037] The insert assembly includes a support plate 401 that is fitted between the front ends of the slide plate 303. A retaining groove 402 is provided on the lower surface of the support plate 401, and a vertical plate 403 is fixedly installed on the upper surface of the support plate 401.

[0038] like Figure 3 As shown, the side wall of the slide groove 302 is provided with a side groove 304, and the side wall of the slide plate 303 is provided with a side plate 305 that cooperates with the side groove 304. With the side plates 305 on both sides embedded in the side groove 304, the slide plate 303 moves upward steadily, squeezing the first telescopic rod 306 and the first spring 307 to make them contract. At this time, it drives the insertion assembly to move upward to the position above the wiring port 2, so that the wiring port 2 opens.

[0039] like Figure 2 As shown, a first telescopic rod 306 is fitted on the vertical upper surface of the slide plate 303. A first spring 307 is fitted on the outer wall of the first telescopic rod 306. When the first telescopic rod 306 and the first spring 307 are pressed together, they retract, which drives the insertion assembly to move upward to the position above the wiring port 2, thus opening the wiring port 2. When wiring is not needed, the upward pull on the slide plate 303 is released, and the first telescopic rod 306 and the first spring 307 push the slide plate 303 downward. Under the limitation of the side plate 305 being embedded in the side groove 304, the slide plate 303 moves downward stably, thereby aligning the insertion post 405 with the wiring port 2.

[0040] like Figure 5 As shown, a through groove 404 is provided in the center of the upright plate 403. A plug 405 that cooperates with the wiring port 2 is movably arranged inside the through groove 404. A sealing ring 406 is fitted on the outer wall of the rear end of the plug 405. When the wiring is not needed, the wiring is pulled out, the first telescopic rod 306 and the first spring 307 push the slide plate 303 downward to align the plug 405 with the wiring port 2. The pulling force of the pull plate 407 is released, and the second telescopic rod 410 and the second spring 411 push the limiting plate 409 backward, causing the plug 405 to be inserted into the aligned through groove 404. The sealing ring 406 is tightly attached to the end of the wiring port 2.

[0041] like Figure 5 As shown, a limiting groove 408 is provided on the side wall of the through groove 404, and a limiting plate 409 that cooperates with the limiting groove 408 is provided on the side wall of the insertion post 405. The second telescopic rod 410 and the second spring 411 push the limiting plate 409 backward, causing the insertion post 405 to be inserted into the aligned through groove 404. The sealing ring 406 is tightly attached to the terminal of the wiring port 2, which improves the sealing and waterproofing effect.

[0042] like Figure 5As shown, a second telescopic rod 410 is provided on the surface of the limiting plate 409 away from the wiring port 2. A second spring 411 is fitted on the outer wall of the second telescopic rod 410. When it is necessary to open the wiring port 2, the pull plate 407 is pulled forward, which causes the insertion post 405 to slide in the through groove 404 away from the wiring port 2. This causes the limiting plate 409 to slide in the limiting groove 408, which compresses and contracts the second telescopic rod 410 and the second spring 411. The slide plate 303 is pulled upward, which causes the support plate 401 to move upward to the upper side of the wiring port 2, so that the wiring head can be inserted into the wiring port 2.

[0043] like Figure 4 As shown, a pull plate 407 is installed on the outer wall of the front end of the insertion post 405. Pulling the pull plate 407 forward causes the insertion post 405 to slide away from the wiring port 2 in the through groove 404, causing the limiting plate 409 to slide in the limiting groove 408 to compress and retract the second telescopic rod 410 and the second spring 411. Pulling the slide plate 303 upward causes the support plate 401 to move up to the upper side of the wiring port 2.

[0044] Specifically, when using this junction box: When wiring the platform scale is required, pull the slide plate 303 upwards to move it up within the slide groove 302. With the side plates 305 embedded in the side grooves 304, the stable upward movement of the slide plate 303 compresses the first telescopic rod 306 and the first spring 307, causing them to contract. At this time, the insertion assembly moves upwards to the upper position of the wiring port 2, opening the wiring port 2. When wiring is not required, release the upward pull on the slide plate 303. The first telescopic rod 306 and the first spring 307 push the slide plate 303 downwards. With the side plates 305 embedded in the side grooves 304, the slide plate 303 moves downwards stably, aligning the insertion post 405 with the wiring port 2, so that the insertion post 405 can be stably inserted into the wiring port 2, achieving a waterproof seal for the wiring port 2. When it is necessary to open the wiring port 2, pull the pull plate 407 forward, causing the insertion post 405 to move away from the wiring port 2 within the through groove 404. The sliding motion of the wire port 2 causes the limiting plate 409 to slide within the limiting groove 408, compressing and contracting the second telescopic rod 410 and the second spring 411. This pulls the sliding plate 303 upward, causing the support plate 401 to move upward to the upper side of the wire port 2, allowing the wire head to be inserted into the wire port 2. Under the downward pushing effect of the first telescopic rod 306 and the first spring 307, the retaining groove 402 is tightly pressed against the wire port 2 and the upper side of the wire, preventing water from flowing into the gap between the wire port 2 and the wire, thus improving the waterproof effect. When the wire is no longer needed, the wire is pulled out, and the first telescopic rod 306 and the first spring 307 push the sliding plate 303 downward to align the insertion post 405 with the wire port 2. The pulling force of the pull plate 407 is released, and the second telescopic rod 410 and the second spring 411 push the limiting plate 409 backward, causing the insertion post 405 to insert into the aligned through groove 404. The sealing ring 406 is tightly pressed against the end of the wire port 2, improving the sealing and waterproof effect.

[0045] All technical features in this embodiment can be freely combined according to actual needs.

[0046] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
