Description

Technical Field

[0001] This utility model relates to the field of wall switches, specifically to a fixing mechanism for a switch socket. Background Technology

[0002] When installing wall switches in the wall, a recessed box is usually pre-installed in the wall, and then the switch body with the panel is fixedly connected to the recessed box. The common connection method between the switch body and the recessed box is direct screw connection. However, in some countries, a metal claw on the switch body is used to hook into the inner wall of the recessed box for fixation. This method is more convenient and faster for wall insertion. For example, the wall-mounted fixing connection structure of a wall switch disclosed in Chinese patent CN209591829U uses a metal claw that engages with a screw. By rotating the screw, the metal claw opens to both sides.

[0003] However, the iron claw has two symmetrically arranged side plates with hooks. Since the two side plates are formed directly by bending, they are prone to deformation after long-term use due to the direct force on the side plates when they are flipped to the sides, which in turn affects the fixing stability of the wall switch. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a fixing mechanism for a switch socket.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0007] Mounting rack;

[0008] The claws are provided on both sides of the mounting bracket, each including a free end, the two sides of the free end are bent to form hook plates, and a connecting part is provided between the two hook plates to connect them together.

[0009] A pressure plate is located at the bottom of the jaws;

[0010] The rotating bolt passes through the mounting bracket, the free end of the chuck, and the pressure plate, respectively, and the rotating bolt is threadedly connected to the pressure plate to form a chuck opening and closing drive structure.

[0011] The connecting part consists of two connecting plates that extend towards each other from the hook plate portion, and the two connecting plates are fixedly connected to each other at the contact end.

[0012] There is an angle of less than 90° between the hook plate and the free end.

[0013] The connection between the hook plate and the free end is provided with an inclined surface for the claws to retract under force.

[0014] The pressure plate extends outward from any one or both ends to form a driving part that cooperates with the inclined surface.

[0015] The mounting bracket is provided with limiting seats on both sides, and the claw is movably disposed within the limiting seats.

[0016] The limiting seat includes side plates arranged symmetrically on the left and right sides and a fixing plate arranged below to form a threaded engagement with the rotating bolt.

[0017] The mounting bracket is also provided with a switch housing, and the switch housing has limiters on both sides to prevent the rotating bolts from coming out.

[0018] One end of the limiting component is provided with an arc-shaped groove.

[0019] The beneficial effects of this utility model are: by adding a connecting piece between the two hook plates of the claw, the strength of the claw is improved, and the deformation will not occur after long-term use, resulting in unreliable connection. Attached Figure Description

[0029] 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.

[0030] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0031] like Figure 1 As shown, this utility model provides a fixing mechanism for a switch socket, which is mainly used to fix a wall switch on the wall. It includes a mounting bracket 100, a claw 300, a pressure plate 500, and a rotating bolt 400. The rotating bolt 400 cooperates with the pressure plate to form a claw opening and closing drive structure. By tightening or loosening the rotating bolt, the pressure plate is moved up and down, thereby causing the claw to open or close.

[0032] All directional indicators in this application (such as up, down, left, right, forward, backward, etc.) are as follows: Figure 2 As shown in the diagram, the closed state is as follows: Figure 2 As shown on the left side, and opened as Figure 2 As shown on the right side of the middle section.

[0033] The mounting bracket 100 is square in shape, with a through hole in the middle to accommodate the switch socket. The aforementioned claw opening and closing drive structure and claws are provided on both sides of the through hole.

[0034] To further restrict the position of the claw, a limiting seat 110 is provided at the bottom of the mounting bracket. The limiting seat is formed by extending downward from the edge of the through hole. The claw 300 is movably disposed in the limiting seat 110. The limiting seat has an opening on the outward side, so that the claw can open outward without restriction.

[0035] like Figure 3 The limiting seat 110 includes symmetrically arranged side plates 111 and a fixed plate 112 located below, which is threadedly engaged with the rotating bolt. The distance between the two side plates is equivalent to the width of the chuck. The design of the fixed plate can limit the maximum movement distance of the pressure plate, and at the same time, the upper wall of the limiting seat and the fixed plate can limit the straightness of the rotating bolt. Additionally, the two side plates can guide the opening and closing of the chuck.

[0036] like Figure 5 and Figure 6 As shown, the claw 300 is disposed on both sides of the mounting bracket 100. It includes a free end 310, and the two sides of the free end 310 are bent to form hook plates 320. A connecting part 330 is provided between the two hook plates 320 to connect them together. The entire claw is integrally formed by sheet metal parts. It unfolds into a long strip shape, and both ends are provided with outward protruding claws. The two ends are bent at 90° to form hook plates. During installation, the claws of the claw will form a limiting engagement with the corresponding parts on the wall. In order to avoid deformation due to the two bent hook plates, this embodiment provides a connecting part that faces and approaches each other on the two hook plates. The two connecting parts extend from the hook plate parts and are formed by bending. The other ends of the two are in contact and form a locking structure. For example, the connection between the two can be welded or a mutually interlocking structure can be set to make the two firmly connected together. The connecting part 330 is two connecting plates formed by the hook plate parts extending towards each other, and the two connecting plates are fixedly connected to each other at the contacting ends. In this embodiment, one end of one connecting plate is configured as a T-shaped component, while one end of the other connecting plate is configured as a concave structure that matches the T-shaped component. The two are joined together to achieve fixation. In some other embodiments, different shaped joining structures can also be used to achieve a fixed connection between the two connecting plates. This increases the strength between the two hook plates by using the connecting part, which can avoid the problem of hook plate deformation due to long-term use and also increase the gripping force of the hook plates.

[0037] Meanwhile, a notch is provided at the upper end of the limiting seat, and the free end of the pawl has a protrusion in the opposite direction to the pawl. The protrusion 340 can be swung and disposed in the notch, and the notch is used to limit the maximum swing angle of the pawl.

[0038] A pressure plate 500 is located at the bottom of the jaw 300. The pressure plate has a sheet-like structure and is arranged parallel to the free end of the jaw.

[0039] Rotating bolt 400 passes through the free end of mounting bracket 100, pawl 300 and pressure plate 500 respectively, and the rotating bolt 400 is threadedly connected to the pressure plate 500 to form a pawl opening and closing drive structure.

[0040] like Figure 7 As shown, when the rotating bolt 400 is under force, it rotates to cause the pressure plate that forms a threaded engagement with it to move along the axis of the rotating bolt. Then, when locking, the pressure plate moves upward and gradually contacts the free end of the pawl, so that the originally inclined free end gradually becomes parallel to the pressure plate and presses the free end, thereby causing the pawl to unfold outward.

[0041] like Figure 8As shown, to achieve the opening and closing of the hook plate, there is an angle of less than 90° between the hook plate 320 and the free end 310. Simultaneously, a strip-shaped hole 350 is provided on the free end 310. That is, when the free end 310 contacts the pressure plate, the hook plate opens outwards, and when the pressure plate moves downwards, the hook plate droops and closes. To further improve the reliability of the closing, in this embodiment, an inclined surface 321 is provided at the connection between the hook plate 320 and the free end 310 for force-driven pawl retraction. One or both ends of the pressure plate 500 extend outwards to form a driving part 510 that cooperates with the inclined surface 321. Figure 9 As shown, when the pressure plate moves downward, its drive unit moves along the inclined plane, causing the chuck to gradually retract inward.

[0042] In existing technologies, to prevent the rotating bolt from coming loose, the bottom of the rotating bolt is typically flattened to make it slightly larger than the diameter of the threaded hole in the pressure plate, thus limiting the bolt's ability to come loose. However, this flattening operation needs to be performed after installation, which is cumbersome and difficult to operate. Figure 4 As shown, in this embodiment, a switch housing mounted on a mounting bracket is used, and limiting members 210 are provided on both sides of the switch housing 200 to prevent the rotating bolt 400 from coming out.

[0043] When it is installed on the mounting bracket, the limiting part presses on the rotating bolt, which prevents it from detaching. By using this method, it is not necessary to flatten the rotating bolt.

[0044] Furthermore, to avoid the influence of the limiting component on the operation of the rotating bolt, one end of the limiting component is provided with an arc-shaped groove, which matches the cross groove or slot of the rotating bolt, so that when the operating bolt is operated, it will not be interfered with by the switch housing.

[0045] The embodiments should not be regarded as limitations on the present invention, but any improvements made based on the spirit of the present invention should be within the protection scope of the present invention.
