Description

Technical Field

[0001] This utility model relates to the field of junction box technology, and in particular to a junction box for low-voltage electrical installation. Background Technology

[0002] Building construction is a part of construction engineering. Building construction refers to the engineering entity formed by the construction of various types of buildings and their ancillary facilities, as well as the installation of supporting lines, pipelines, and equipment. During the construction process, it is necessary to test the verticality of the building to prevent the building from tilting.

[0003] A search revealed Chinese patent number CN222508715U, a junction box for low-voltage installation, comprising a PVC box body. The top surface of the PVC box body has a cover storage groove, with the top surface of the groove closely attached to the bottom surface of the cover. The advantages are: This utility model proposes a junction box for low-voltage installation where, when wires are passed through the conduit on the surface of the PVC box body, the wires can be neatly wound around the surface of the winding post, preventing the wires from becoming tangled inside the PVC box body. By fixing the base of the first bearing ring to the top surface of the winding post, and by rotating the knob, the cover is compressed and locked inside the cover storage groove, thus sealing the wires inside the PVC box body. Rotating the knob in reverse to disengage it from the limiting latch allows the cover to be removed from the cover storage groove, facilitating quick installation and removal of the cover.

[0004] The aforementioned technology requires fixing the cable separately before closing the cover. This step-by-step operation is cumbersome, increasing the steps and time costs of low-voltage installation and reducing construction efficiency. Furthermore, separate operations can easily lead to the cable not being securely fixed or the cover not being closed properly, potentially causing the cable to loosen or fall off, affecting the stability of the low-voltage system and even posing safety hazards. In addition, the cumbersome operation also increases the skill requirements for operators, making it difficult to learn quickly, which is particularly inconvenient in batch installations or emergency construction scenarios. Utility Model Content

[0005] The purpose of this utility model is to provide a junction box for low-voltage electrical installation, which can solve the problem of the above-mentioned technology that requires fixing the wires separately and then closing the cover. This step-by-step operation process is cumbersome, which increases the steps and time costs of low-voltage electrical installation and reduces construction efficiency. At the same time, separate operation is prone to problems such as the wires not being firmly fixed or the cover not being closed properly, which may lead to the wires becoming loose or falling off, affecting the stability of the low-voltage system and even posing safety hazards. In addition, the cumbersome operation also increases the skill requirements of the operators, which is not conducive to quick mastery, especially in batch installation or emergency construction scenarios.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a junction box for low-voltage installation, comprising a junction box body, and further comprising:

[0007] A clamping element is disposed on one side of the cable box body;

[0008] A cover is provided on one side of the junction box body for sealing the junction box body;

[0009] Limiting components are provided on the outer sides of both ends of the wiring box body;

[0010] The first clamping head is fixedly mounted on one side of the cover.

[0011] In a preferred embodiment, the clamping member includes:

[0012] The first mounting plate is fixedly installed on one side of the junction box body;

[0013] The first rotating arm is rotatably mounted on one side of the first mounting plate;

[0014] The second rotating arm is rotatably disposed on the outer side of one end of the first rotating arm;

[0015] The third rotating arm is rotatably disposed on the outer side of the end of the second rotating arm, and the outer side of the top end of the third rotating arm is connected to one side of the cover.

[0016] The second mounting plate is fixedly installed on the other side of the junction box body;

[0017] A limiting groove is formed on the inner side of the second mounting plate;

[0018] The first limiting post is fixedly disposed on one side of the third rotating arm and is used to limit the third rotating arm.

[0019] The second limiting post is fixedly installed on one side of the third rotating arm to limit the movement of the third rotating arm.

[0020] In a preferred embodiment, the limiting groove is composed of a strip structure and an arc structure, and the first limiting post and the second limiting post are disposed on the inner side of the limiting groove.

[0021] In a preferred embodiment, a motor is mounted on one side of the first mounting plate, and the outer side of the motor's main shaft is connected to one side of the first rotating arm.

[0022] In a preferred embodiment, a connecting rod is rotatably provided on one side of the second rotating arm, the connecting rod being used to cause the third rotating arms on both sides to move synchronously.

[0023] In a preferred embodiment, the limiting member includes:

[0024] The second clamping head is fixedly disposed on the outer side of one end of the cable box body. Both the first clamping head and the second clamping head are semi-circular structures.

[0025] In a preferred embodiment, a plurality of winding rods are rotatably arranged on the inner side of the bottom end of the threading box body for organizing the thread.

[0026] In a preferred embodiment, handles are fixedly provided on the outer sides of both ends of the junction box body.

[0027] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0028] In use, after starting the motor, the motor drives the first rotating arm to rotate, pushing one end of the second rotating arm to move and rotate towards the third rotating arm. This pushes the third rotating arm outward, simultaneously causing the first and second limiting posts to move inside the limiting groove until the first limiting post abuts against the inner side of the end of the limiting groove's strip structure. At this point, the rotation of the first rotating arm drives the third rotating arm to rotate around the first limiting post as its axis, rotating the second limiting post into the inner side of the limiting groove's arc-shaped structure. This causes the two covers to first move outward and then unfold outward, facilitating quick and easy installation of the cable. After installation, starting the motor in reverse pulls the third rotating arm back to the side of the first mounting plate via the first and second rotating arms, allowing the covers to close quickly. The entire process, through simple starting and reversing operations, enables the opening and closing of the covers, significantly simplifying the cable installation process and making low-voltage installation more efficient and convenient.

[0037] 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. Example 1

[0038] Please see Figure 1 - Figure 6 This embodiment provides a junction box for low-voltage installation that facilitates quick and easy sealing of the junction box body 1. The specific concept is as follows:

[0039] The junction box for low-voltage installation includes a junction box body 1. In addition, the junction box for low-voltage installation also includes a cover 2 disposed on the outer top of the junction box body 1. The cover 2 is used to quickly close the opening of the junction box body 1, which facilitates the maintenance of the junction box body 1 and the installation of the wires inside it.

[0040] In order to drive the cover 2, this embodiment provides a clamping member. The clamping member can drive the cover 2 to extend outward and then rotate it, so that the opening of the wire box body 1 can be exposed to the outside. The clamping member can also quickly close the cover 2.

[0041] The clamping component in this embodiment includes: a first mounting plate 201 fixedly connected to one side of the cable box body 1; a first rotating arm 203 rotatably connected to one side of the first mounting plate 201; a second rotating arm 204 rotatably connected to the outer side of one end of the first rotating arm 203, the first rotating arm 203 driving the second rotating arm 204 to rotate; a third rotating arm 205 rotatably connected to the outer side of the end of the second rotating arm 204, the outer side of the top end of the third rotating arm 205 fixedly connected to one side of the cover 2, the third rotating arm 205 driving the cover 2 to move; a second mounting plate 206 fixedly connected to the other side of the cable box body 1; and a limiting groove 207 formed in the second mounting plate 206. Inside, the first limiting post 208 is fixedly connected to one side of the third rotating arm 205 to limit the third rotating arm 205. The second limiting post 209 is fixedly connected to one side of the third rotating arm 205 to limit the third rotating arm 205. The limiting groove 207 is composed of a strip structure and an arc structure. The first limiting post 208 and the second limiting post 209 are set inside the limiting groove 207. A motor 202 is installed on one side of the first mounting plate 201. The outer side of the main shaft of the motor 202 is connected to one side of the first rotating arm 203. A connecting rod 210 is rotatably connected to one side of the second rotating arm 204. The connecting rod 210 is used to make the third rotating arms 205 on both sides move synchronously.

[0042] In the specific implementation process: When using the device, the user can start the motor 202. The motor 202 drives the first rotating arm 203 to rotate. Simultaneously, the rotation of the first rotating arm 203 pushes one end of the second rotating arm 204 to move, while also rotating towards the direction of the third rotating arm 205. This pushes the third rotating arm 205 outwards, causing the first limiting post 208 and the second limiting post 209 to move inside the limiting groove 207 until the first limiting post 208 abuts against the inner side of the strip-shaped end of the limiting groove 207. At this point, the first rotating arm 203 rotates, and... The third rotating arm 205 rotates around the axis of the first limiting post 208, while simultaneously rotating the second limiting post 209 into the arc-shaped structure of the limiting groove 207. At this time, the two covers 2 can be driven to unfold outward. The movement trajectory of the covers 2 is to first move outward and then unfold outward. Users can fix and install the line body, which is convenient and quick. After installation, simply start the motor 202 in reverse, and the third rotating arm 205 will be pulled back to one side of the first mounting plate 201 through the first rotating arm 203 and the second rotating arm 204, so that the covers 2 can be closed quickly. Example 2

[0043] Please see Figure 1 - Figure 6 This embodiment provides a junction box for low-voltage installation that facilitates quick and easy clamping and positioning of wires. The specific concept is as follows:

[0044] The junction box for low-voltage installation includes a junction box body 1. In addition, the junction box for low-voltage installation also includes a cover 2 disposed on the outer top of the junction box body 1. The cover 2 is used to quickly close the opening of the junction box body 1, which facilitates the maintenance of the junction box body 1 and the installation of the wires inside. It also includes a second clamping head 301 fixedly connected to one side of the junction box body 1 and a first clamping head 3 fixedly connected to one side of the cover 2 for clamping the wires.

[0045] In order to achieve the clamping function of the first clamping head 3 and the second clamping head 301, this embodiment provides a limiting member, which can limit the outer side of the line body. Through the linkage effect of the cover 2, the outer side of the line body can be clamped and limited while the cover 2 is closed.

[0046] The limiting component in this embodiment includes: a second clamping head 301 fixedly connected to the outer side of one end of the cable box body 1; both the first clamping head 3 and the second clamping head 301 are semi-circular structures; a plurality of winding rods 302 for organizing the cable are rotatably connected to the inner side of the bottom end of the cable box body 1; and handles 303 are fixedly connected to the outer sides of both ends of the cable box body 1.

[0047] In the specific implementation process: the movement trajectory of the cover 2 is to first move outward and then unfold outward. After the cover 2 moves outward, the user can pass the cable through the first clamping head 3 and the second clamping head 301, and at the same time wrap it around the outside of the winding bar 302 to organize the cable. After the cable end is installed and fixed, the user resets the cover 2. At the same time, the lowering of the cover 2 will clamp the outside of the cable through the first clamping head 3 and the second clamping head 301, thereby clamping and limiting the cable. The operation is quick and easy. The cable is clamped and limited by the linkage between the opening and closing of the cover 2.

[0048] Working principle:

[0049] Based on Embodiment 1, this wiring box for low-voltage installation has significant advantages. After the user starts the motor 202, the motor 202 drives the first rotating arm 203 to rotate, pushing one end of the second rotating arm 204 to move and rotate towards the third rotating arm 205, thereby pushing the third rotating arm 205 outward. At the same time, it drives the first limiting post 208 and the second limiting post 209 to move inside the limiting groove 207 until the first limiting post 208 abuts against the inner side of the end of the strip structure of the limiting groove 207. At this time, the rotation of the first rotating arm 203 drives the third rotating arm 205 to rotate around the first limiting post 208 as the axis, turning the second limiting post 209 into the inner side of the arc structure of the limiting groove 207, so that the two covers 2 first move outward and then unfold outward, making it convenient for the user to quickly fix and install the wiring. After installation, the motor 202 is started in reverse, and the third rotating arm 205 is pulled back to one side of the first mounting plate 201 by the first rotating arm 203 and the second rotating arm 204, so that the cover 2 can be quickly closed. The entire system can be opened and closed with simple start and reverse start operations, which greatly simplifies the installation process and makes low-voltage installation more efficient and convenient.

[0050] Building upon Example 2, this cable box for low-voltage installation offers significant advantages. The cover 2 moves outward first and then unfolds outward. After the cover 2 moves outward, the user can pass the cable through the first clamping head 3 and the second clamping head 301, while simultaneously winding the cable around the outside of the winding bar 302. After the cable end is fixed, when the user resets the cover 2, the first clamping head 3 and the second clamping head 301 clamp the outside of the cable during the descent of the cover 2, thus achieving clamping and limiting of the cable. The entire process is quick and easy. The clamping and limiting of the cable is achieved through the linkage of opening and closing of the cover 2, which not only facilitates the arrangement and installation of the cable but also efficiently fixes the cable, greatly improving the convenience and efficiency of cable handling in low-voltage installation.

[0051] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
