Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a plastering protective cover device. Background Technology

[0002] During building construction, it is necessary to protect the pre-drilled holes for switches and sockets when plastering walls to ensure that these holes are not covered by mortar during the plastering process. This prevents mortar from clogging the holes and affecting the subsequent installation of wires and cover plates. In existing technology, pre-drilled holes for switches and sockets are often temporarily covered with tape, foam, or sawdust.

[0003] However, the above method has the following drawbacks:

[0004] 1. Poor sealing allows mortar to easily enter the pre-drilled holes in the switches and sockets, making cleaning and subsequent installation difficult;

[0005] 2. After disassembly, mortar residue may remain at the edges of the opening, affecting its squareness and hindering the installation of the cover plate;

[0006] 3. It wastes disposable materials and generates a large amount of garbage, which does not meet the requirements of green construction. Summary of the Invention

[0007] To address the aforementioned technical problems, this utility model proposes a plastering protective cover device for reserved holes in switches and sockets, which solves the problem that existing protective measures can easily allow mortar to enter the reserved holes in switches and sockets, leading to difficulties in cleaning and subsequent installation.

[0008] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0009] A plastering protective cover device for a reserved hole in a switch socket includes an inner cover plate for insertion into the reserved hole and a tightening mechanism disposed within the inner cover plate to support the plastering protective cover device against the inner wall of the reserved hole; an outer cover plate is also provided on the outer side of the inner cover plate for covering the outer side of the reserved hole in the switch socket.

[0010] Furthermore, the clamping mechanism includes a clamping assembly that rotates with the inner cover plate and a clamping follower disposed on the inner cover plate. After the clamping assembly rotates, it clamps with the clamping follower to drive the clamping follower to move outward to support the inner wall of the reserved hole of the switch socket.

[0011] Furthermore, the longitudinal sections of both the outer cover plate and the inner cover plate are rectangular or square.

[0012] Furthermore, the clamping assembly is inserted through the outer cover plate such that one end of the clamping assembly protrudes outside the outer cover plate and the other end is located inside the inner cover plate.

[0013] Furthermore, the inner cover plate is provided with a transverse break to divide the inner cover plate into two parts for supporting the inner wall of the reserved hole of the switch socket.

[0014] Furthermore, the clamping assembly includes a rotating rod passing through the outer cover plate and a clamping member disposed at the inner end of the rotating rod. The longitudinal section of the clamping member is elliptical so that the outer side of the clamping member forms an elliptical surface, and the rotating rod is perpendicular to the major axis and minor axis of the ellipse. The clamping follower is a rectangular plate symmetrically disposed on the inner side of the inner cover plate. The side of the rectangular plate parallel to the side wall of the inner cover plate contacts and engages with the elliptical surface of the clamping member so that after the clamping member rotates, it pushes the rectangular plate outward, thereby causing the inner cover plate to clamp the inner wall of the reserved hole of the switch socket.

[0015] Furthermore, the clamping assembly includes a rotating rod passing through the outer cover plate and a clamping member disposed at the inner end of the rotating rod. The clamping member is a truncated cone structure with a circular longitudinal section, and the rotating rod is coaxially arranged with the truncated cone structure. The clamping driven member is a symmetrically arranged inclined plate block on the inner side of the inner cover plate, and the inclined surface of the inclined plate block contacts and engages with the conical surface of the truncated cone structure. The rotating rod is threadedly connected to the outer cover plate so that the rotation of the rotating rod drives the movement of the truncated cone structure, thereby pushing the inclined plate block and the inner cover plate outward to support the inner wall of the reserved hole of the switch socket.

[0016] Furthermore, the clamping assembly includes a rotating rod passing through the outer cover plate and a clamping member disposed at the inner end of the rotating rod. The longitudinal section of the clamping member is elliptical so that the outer side of the clamping member forms an elliptical surface, and the rotating rod is perpendicular to the major axis and minor axis of the ellipse. The clamping driven member includes a sleeve symmetrically and vertically disposed on the inner side of the inner cover plate, and a sliding member slidingly passing through the side wall of the inner cover plate and the sleeve. The end of the sliding member away from the inner cover plate contacts and engages with the side of the clamping member facing the inner wall of the inner cover plate so that after the clamping member rotates, it clamps the sliding member and moves it outward to support the inner wall of the reserved hole of the switch socket.

[0017] Furthermore, the sliding member includes a sliding rod with one end passing through the inner cover plate and a boss connected to the other end of the sliding rod. The diameter of the boss is larger than the diameter of the sliding rod so that the connection between the boss and the sliding rod forms an annular platform. A spring is provided between the annular platform and the inner cover plate, and the spring is sleeved on the sliding rod. The end of the boss away from the sliding rod is engaged with a clamping member.

[0018] Furthermore, a rotating handle is connected to the outer end of the rotating rod.

[0019] The beneficial effects of this utility model are:

[0020] 1. This utility model provides protection by inserting an inner cover plate into the reserved hole of the switch socket, and also makes it easier to install the device on the reserved hole of the switch socket.

[0021] 2. This utility model provides an outer cover plate that covers the outside of the opening, with the outer cover plate protruding beyond the outer side of the inner cover plate, thus reserving a position for installing a switch or socket panel on the outside of the reserved hole for the switch and socket.

[0022] 3. This utility model has a tightening member inserted through the outer cover plate and a tightening follower set on the inner side of the inner cover plate. The inner cover plate has two disconnected parts. When the tightening member is rotated, the tightening member gradually pushes the tightening follower outward, thereby causing the two parts of the inner cover plate to shift outward, thereby pressing against the inner wall of the reserved hole of the switch socket, thus supporting the device in the reserved hole of the switch socket, making the device more stable.

[0023] 4. This utility model provides a rotating handle at the outer end of the clamping member, which facilitates the rotation of the clamping member, making the device easy to install and disassemble, convenient for repeated use, and improving its practicality. Attached Figure Description

[0031] 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.

[0032] like Figure 1 As shown in Embodiment 1 of this utility model, a plastering protective cover device for a pre-drilled hole in a switch or socket includes an inner cover plate 6 for insertion into the pre-drilled hole, facilitating the installation of the device. In this embodiment, the inner cover plate 6 is a rectangle or square with the same shape as the pre-drilled hole in the switch or socket; and the inner cover plate 6 includes four side plates forming a rectangle or square, which are respectively used to fit against the inner wall of the pre-drilled hole in the switch or socket, playing a preliminary role in protecting the pre-drilled hole. An outer cover plate 1 is also provided on the outside of the inner cover plate 6 for covering the outside of the pre-drilled hole in the switch or socket. The outer cover plate 1 includes at least four side plates forming a rectangle or square, so that a position for installing a switch or socket panel is reserved on the outside of the pre-drilled hole in the switch or socket during the plastering process. Furthermore, the four sides of the rectangle or square are parallel to the four sides of the rectangle or square formed on the inner cover plate 6. The plastering protective cover device also includes a clamping mechanism disposed in the inner cover plate 6 to ensure that the plastering protective cover device is tightly supported against the inner wall of the pre-drilled hole in the switch or socket. In this embodiment, the tightening mechanism is installed on the outer cover plate 1 so that a part of the tightening mechanism is exposed on the outside of the outer cover plate 1, which facilitates control of the tightening mechanism from the outside. The other part of the tightening mechanism is located on the inside of the inner cover plate 6, which facilitates the tightening mechanism to act on the inner cover plate 6 or directly on the reserved hole of the switch socket, so that the inner cover plate 6 is pressed against the inner wall of the reserved hole of the switch socket or the tightening mechanism is directly pressed against the inner wall of the reserved hole of the switch socket, thereby making the plastering protective cover plate device stably installed on the reserved hole of the switch socket, and playing a stable protective role.

[0033] Furthermore, such as Figure 1 As shown, the clamping mechanism includes a clamping assembly that rotates with the outer cover plate 1 and a clamping follower 4 disposed on the inner cover plate 6. After the clamping assembly rotates, it clamps with the clamping follower 4 to drive the clamping follower 4 to move outward to support the inner wall of the reserved hole of the switch socket.

[0034] Example 2 differs from Example 1 in that, as Figure 1 As shown, the inner cover plate 6 is provided with a transverse break 5 to break the inner cover plate 6 into two parts, so that the two parts can have a certain amount of outward displacement to support the inner wall of the reserved hole of the switch socket.

[0035] Example 3 differs from Example 2 in that, as Figure 1 As shown, Figure 1and Figure 2 As shown, the clamping assembly includes a rotating rod 7 passing through the outer cover plate 1 and a clamping member 3 disposed at the inner end of the rotating rod 7. The outer cover plate 1 includes four side plates forming a rectangle or rectangle and an end plate connected to the same end of the four side plates, with the end plate located at the outermost end. The rotating rod 7 passes perpendicularly through the end plate and is rotatably connected to the end plate to drive the clamping member 3 to rotate. In a preferred embodiment, the rotating rod 7 can be rotatably connected to the end plate via a damping bearing. The longitudinal section of the clamping member 3 is elliptical so that the outer side of the clamping member 3 forms an elliptical surface, and the rotating rod 7 is perpendicular to the major and minor axes of the ellipse. That is, the cross section of the clamping member 3 in the direction perpendicular to the side wall of the inner cover plate 6 is elliptical so that the outer side of the clamping member 3 forms an elliptical surface, such that the elliptical surface of the clamping member 3 faces the side wall of the inner cover plate 6. The clamping follower 4 consists of two rectangular plates symmetrically disposed on the inner side wall of the inner cover plate 6. In this embodiment, the clamping member 3 is located between the two rectangular plates. Initially, the side of the rectangular plate parallel to the sidewall of the inner cover plate 6 is in contact with the portion of the elliptical surface of the clamping member 3 located at both ends of the minor axis of the ellipse. After the clamping member 3 rotates, the portion of the elliptical surface of the clamping member 3 located at both ends of the major axis of the ellipse is tightly engaged with the corresponding side of the rectangular plate, so that the rotation of the clamping member 3 pushes the two rectangular plates outward, and the rectangular plates in turn drive the two disconnected parts of the inner cover plate 6 to be pushed outward, thereby making the inner cover plate 6 support the inner wall of the reserved hole of the switch socket. Furthermore, the gap between the sidewall of the inner cover plate 6 and the inner wall of the reserved hole of the switch socket is small, so that the deformation of the inner cover plate 6 supporting the inner wall of the reserved hole of the switch socket is small, thus making the inward reaction force of the inner cover plate 6 small. Moreover, the friction between the elliptical surface of the clamping member 3 and the side of the rectangular plate that is engaged with it and the friction between the rotating rod 7 and the end plate are greater than the reaction force of the inner cover plate 6, so as to prevent the clamping member 3 from being rotated by the reaction force.

[0036] Furthermore, a rotating handle 2 is connected to the outer end of the rotating rod 7 for rotating the clamping member 3. In addition, the four side plates of the inner cover plate 6 can be connected to the end plates.

[0037] Example 4 differs from Example 2 in that, as Figure 4 As shown, the clamping assembly includes a rotating rod 7 passing through the outer cover plate 1 and a clamping member 3 disposed at the inner end of the rotating rod 7. The outer cover plate 1 includes four side plates forming a rectangle or rectangle and an end plate connected to the same end of the four side plates, with the end plate located at the outermost end. The rotating rod 7 passes perpendicularly through the end plate and is rotatably connected to the end plate. Furthermore, the rotating rod 7 is threadedly connected to the end plate of the outer cover plate 1 so that the rotating rod 7 can rotate and move simultaneously, thereby driving the movement of the clamping member 3. An external thread is provided on the outer side of the rotating rod 7, and an internal threaded hole that mates with the external thread is provided on the end plate.

[0038] Furthermore, the clamping member 3 is a truncated cone structure, and the longitudinal section of the clamping member 3 is circular, that is, the side view projection of the clamping member 3 is circular, and the top view projection is trapezoidal. The rotating rod 7 is coaxially arranged with the truncated cone structure, allowing the rotating rod 7 and the truncated cone structure to rotate coaxially. The clamping follower 4 consists of two inclined plate blocks symmetrically arranged on the inner wall of the inner cover plate 6. The inclined surfaces of the two inclined plate blocks form an approximately V-shaped groove. The inclined surfaces of the two inclined plate blocks contact and engage with the conical surface of the truncated cone structure, so that the rotation of the rotating rod 7 drives the movement of the truncated cone structure, thereby pushing the inclined plate blocks outward and thus tightening the inner wall of the switch socket pre-drilled hole of the inner cover plate 6. Initially, the small end of the truncated cone structure engages with the inclined surface of the inclined plate block located at the V-shaped groove opening. This engagement can be a contact engagement or a slightly gapped engagement, but the gap is less than the difference in radii between the large and small ends of the truncated cone structure. After the rotating clamping member 3 moves the truncated cone structure, the truncated cone structure gradually penetrates into the V-groove. The conical surface of the truncated cone structure gradually presses against the inclined plate blocks, thereby pushing the two inclined plate blocks outward. The inclined plate blocks drive the two parts of the disconnected inner cover plate 6 to move outward and tighten the inner wall of the reserved hole of the switch socket. Furthermore, the two ends of the threaded connection between the rotating rod 7 and the end plate are provided with limiting parts, so that the moving stroke of the clamping member 3 is less than the thickness of the truncated cone structure, that is, less than the distance between the small end and the large end of the truncated cone structure.

[0039] Furthermore, such as Figure 3 As shown, the outer end of the rotating rod 7 is connected to a rotating handle 2 for rotating the clamping member 3. In this embodiment, the rotating rod 7 is provided with a limiting plate or limiting protrusion on the inner side of the outer cover plate 1 to limit the extreme position of the rotating rod 7 moving outward; the rotating handle 2 is used to limit the extreme position of the rotating rod 7 moving inward into the outer cover plate 1. The distance between the limiting plate or limiting protrusion and the rotating handle 2 is less than the thickness of the frustum structure plus the thickness of the end plate, so that the travel of the clamping member 3 is less than the thickness of the frustum structure.

[0040] In addition, the four side plates of the inner cover plate 6 can be connected to the end plate.

[0041] Example 5 differs from Example 1 in that, as Figure 5As shown, the clamping assembly includes a rotating rod 7 passing through the outer cover plate 1 and a clamping member 3 disposed at the inner end of the rotating rod 7. The outer cover plate 1 includes four side plates forming a rectangle or rectangle and an end plate connected to the same end of the four side plates, with the end plate located at the outermost end. The rotating rod 7 passes perpendicularly through the end plate and is rotatably connected to the end plate to drive the clamping member 3 to rotate. In a preferred embodiment, the rotating rod 7 can be rotatably connected to the end plate via a damping bearing. The longitudinal section of the clamping member 3 is elliptical so that the outer side of the clamping member 3 forms an elliptical surface, and the rotating rod 7 is perpendicular to the major and minor axes of the ellipse. That is, the cross section of the clamping member 3 in the direction perpendicular to the side wall of the inner cover plate 6 is elliptical, such that the elliptical surface of the clamping member 3 faces the side wall of the inner cover plate 6. The clamping follower 4 includes two sleeves 41 symmetrically and vertically arranged on the inner sidewall of the inner cover plate 6, and a sliding member 42 slidably passing through the sidewall of the inner cover plate 6 and the sleeves 41. That is, each of the two sleeves 41 has a sliding member 42, and the sliding member 42 passes through the sidewall of the inner cover plate 6. The sliding member 42 is slidably engaged with the sleeves 41 and the sidewall of the inner cover plate 6 so that the outer end of the sliding member 42 can directly contact and clamp the inner wall of the reserved hole of the switch socket. In this embodiment, the clamping member 3 is located between the two sliding members 42. The end of the sliding member 42 away from the inner cover plate 6 contacts and engages with the elliptical surface of the clamping member 3 so that when the clamping member 3 rotates, it clamps the sliding member 42 to move outward, so that the outer end of the sliding member 42 clamps the inner wall of the reserved hole of the switch socket.

[0042] Furthermore, the sliding member 42 includes a sliding rod that slides through the inner cover plate 6 at one end and a boss connected to the other end of the sliding rod. The diameter of the boss is larger than the diameter of the sliding rod so that the connection between the boss and the sliding rod forms an annular platform. A spring 43 is provided between the annular platform and the inner cover plate 6, and the spring 43 is sleeved on the sliding rod. The end of the boss away from the sliding rod is engaged with the clamping member 3.

[0043] Initially, the inner end of the sliding member 42 is in contact with the portion of the elliptical surface of the clamping member 3 located at both ends of the minor axis of the ellipse. After the clamping member 3 rotates, the portion of the elliptical surface of the clamping member 3 located at both ends of the major axis of the ellipse is tightly engaged with the inner end of the sliding member 42, so that the rotation of the clamping member 3 pushes the sliding member 42 outward, and after the two sliding members 42 move outward, they press against the inner wall of the reserved hole of the switch socket.

[0044] Furthermore, the gap between the side wall of the inner cover plate 6 and the inner wall of the reserved hole in the switch socket is small, resulting in a small displacement of the sliding rod when it is pressed against the inner wall of the reserved hole in the switch socket, thus reducing the elastic deformation of the spring 43 after being compressed. Also, the friction between the elliptical surface of the clamping member 3 and the end face of the boss, and the friction between the rotating rod 7 and the end plate, are greater than the reaction force of the spring 43's elastic reset, thus preventing the clamping member 3 from being rotated by the reaction force.

[0045] Furthermore, a rotating handle 2 is connected to the outer end of the rotating rod 7 for rotating the clamping member 3. In addition, the four side plates of the inner cover plate 6 can be connected to the end plates.

[0046] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that any modifications to the technical solutions described in the foregoing embodiments, or equivalent substitutions of some or all of the technical features thereof, within the spirit and principles of the present invention, do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and should all be included within the protection scope of the present invention.
