Description

Technical Field

[0001] This application relates to the field of hardware and electrical technology, and more specifically, to an electrical socket for building applications. Background Technology

[0002] Currently, commercially available portable power strips are commonly used on construction sites as temporary power sources. These power strips have multiple sockets connected in parallel within a plastic casing, and the input end is connected to a distribution box or wall socket via a 2-5m flexible cable. The flexible cable is fixed to the power strip casing by a single injection molding or simple clips. When workers drag the plug or move equipment, the internal wires can easily be pulled off from the copper strip solder joints, causing a momentary power outage and affecting continuous operations such as concrete vibration and cutting.

[0003] A search revealed that Chinese patent CN221885494U discloses an electrical socket for building use. This device, by setting a clamping and anti-detachment mechanism, installs a pressure plate on a fixed ring. Under the elastic force of the clamping spring, the clamping block can clamp the wire, thereby preventing the wire from falling off due to being dragged during construction. This helps to ensure the efficiency of construction and reduce safety hazards, thus improving the safety of the socket.

[0004] While the clamping and anti-detachment mechanism of the aforementioned device can prevent the socket's wires from coming loose, the bent ends of the wires can still experience excessive stress when subjected to external pulling, leading to cracks in the outer protective layer and posing a safety hazard. Therefore, we propose a building electrical socket. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] The purpose of this application is to provide an electrical socket for building applications to solve the problems mentioned in the background art.

[0007] 2. Technical Solution

[0008] This application is achieved through the following technical solution:

[0009] An electrical socket for building includes a socket body, a wire on one side of the socket body, a groove at the bottom of the socket body, a slider and an elastic element in the groove, the slider being slidably disposed in the groove, the slider being elastically connected to the socket body through the elastic element, a pulley being rotatably mounted at the bottom of the slider, one end of the wire being fixedly installed to the socket body, and the other end passing over the pulley.

[0010] As an optional solution to the technical solution of this application, the bottom of the socket body is provided with a first slot and a second slot, the wire is fixedly disposed in the first slot, the wire is slidably disposed in the second slot, and the connection between the first slot and the wire is close to the connection between the socket body and the wire.

[0011] As an optional solution to the technical solution of this application, two clamping rods are rotatably connected in the first slot. The two clamping rods are arranged in a symmetrical structure. The clamping rods are capable of elastic deformation. A spring piece is fixedly connected to the side of the clamping rod near the inner wall of the first slot. The wire is limited in the first slot by the two clamping rods.

[0012] As an optional solution to the technical solution of this application, the lower part of the inner wall on both sides of the second slot is provided with a flange, and the wire is limited in the second slot by the flange.

[0013] As an optional solution to the technical solution in this application, a cover plate is fixedly connected to the bottom of the socket body. The cover plate is located below the pulley, which is shaped like a frustum. The bottom diameter of the pulley is smaller than the top diameter, and the cover plate does not completely cover the groove.

[0014] 3. Beneficial effects

[0015] Compared with the prior art, the beneficial effects of this application are:

[0016] 1) This application provides a pulley at the bottom of the socket body. When the wire is pulled, the wire can drive the pulley to move, compress the elastic element, and release the wire, thus preventing the wire from falling off the socket body or causing the outer protective layer of the wire to break.

[0017] 2) By setting the pulley to a frustum shape, this application makes the wire's internal force too large. When the pulley is pushed out from under the cover plate, the wire can be detached from the pulley, allowing the wire to be further released and straightened, thus providing further protection and increasing the stability and safety of the socket body.

[0023] The technical solution of this application will now be clearly and completely described in conjunction with the accompanying drawings.

[0024] Please see Figure 1 and Figure 2 This application provides a technical solution:

[0025] An electrical socket for building includes a socket body 1, a wire 2 on one side of the socket body 1, a groove 101 at the bottom of the socket body 1, a slider 3 and an elastic element 4 in the groove 101, the slider 3 is slidably disposed in the groove 101, the slider 3 is elastically connected to the socket body 1 through the elastic element 4, a pulley 5 is rotatably mounted at the bottom of the slider 3, one end of the wire 2 is fixedly installed to the socket body 1, and the other end passes around the pulley 5.

[0026] In this solution, by passing the wire 2 around the pulley 5, when the wire 2 is pulled, the wire 2 can act on the pulley 5, so that the pulley 5 slides in the groove 101 through the slider 3 and compresses the elastic element 4, thereby releasing the wire 2 and reducing the tension of the wire 2. This prevents the internal tension of the wire 2 from being too high, which could cause the wire 2 to detach from the socket body 1 or the protective layer of the bent part of the wire 2 to break.

[0027] Preferably, a cover plate 7 is fixedly connected to the bottom of the socket body 1. The cover plate 7 is located below the pulley 5, which is frustum-shaped with a smaller bottom diameter than the top diameter. The cover plate 7 does not completely cover the groove 101. When the wire 2 is tightened, it can pull the pulley 5 to move. When the internal tension of the wire 2 is too high, causing the pulley 5 to move out of the cover plate 7, the wire 2 can slide downward on the surface of the pulley 5 and then fall off the pulley 5, thereby releasing the wire 2 and further reducing the internal tension of the wire 2.

[0028] like Figure 3 and Figure 4 As shown, the bottom of the socket body 1 is provided with a first slot 102 and a second slot 103. The wire 2 is fixedly installed in the first slot 102 and slidably installed in the second slot 103. The connection between the first slot 102 and the wire 2 is close to the connection between the socket body 1 and the wire 2. Two clamping rods 6 are rotatably connected in the first slot 102. The two clamping rods 6 are arranged in a symmetrical structure and can undergo elastic deformation. A spring piece is fixedly connected to the side of the clamping rod 6 near the inner wall of the first slot 102. The wire 2 is limited in the first slot 102 by the two clamping rods 6.

[0029] In this design, by rotating the clamping rod 6 into the first slot 102 and then placing the wire 2 between the two clamping rods 6, the outer spring of the clamping rod 6 can be pressed against the inner wall of the first slot 102, thereby pushing the clamping rod 6 to move towards the wire 2 and completing the clamping and fixing of the wire 2. When the wire 2 is pulled, since the wire 2 is fixed in the first slot 102, the stress state at the connection between the socket body 1 and the wire 2 can be prevented from changing, thus protecting the connection between the socket body 1 and the wire 2. When the wire 2 falls off the pulley 5, during the continued pulling process, the wire 2 will be dragged to the outside of the first slot 102. The clamping rod 6 can rotate out of the first slot 102 along with the wire 2. After the clamping rod 6 moves to the outside of the first slot 102, it will lose its clamping effect on the wire 2, allowing the wire 2 to be straightened and reducing the damage caused by external pulling.

[0030] Preferably, the lower part of the inner wall on both sides of the second slot 103 is provided with a flange, and the wire 2 is limited in the second slot 103 by the flange. When the wire 2 is pulled, it can slide in the second slot 103, preventing the wire 2 from falling out of the second slot 103.
