Description

Technical Field

[0001] This utility model relates to the technical field of cable trays, specifically a cover plate locking structure and a tray cable tray. Background Technology

[0002] Tray-type cable trays are devices used to support, protect, and manage cables. They are widely used in construction, industrial facilities, power systems, and other fields, and have advantages such as light weight, high load capacity, simple structure, and easy installation. Tray-type cable trays are generally divided into two types: with covers and without covers. Tray-type cable trays with covers can better protect cables and prevent damage from the external environment, such as dust prevention, moisture prevention, and sun shading.

[0003] In the design of tray-type cable trays, there are various ways to install the cover plates. The traditional fixing method uses bolts, which requires the use of auxiliary tools to align the cover plate with the screw holes on the cable tray before fixing. This makes the installation process cumbersome and reduces the efficiency of installing the tray-type cable tray and the cover plate. Utility Model Content

[0004] The purpose of this invention is to provide a cover plate locking structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A cover plate locking structure includes a cable tray body and a cover plate body that can be detachably installed with the cable tray body;

[0007] At least one set of elastic triggers are symmetrically arranged at both ends of the inner side of the cover plate body. When the cover plate body is installed, the elastic triggers are deformed by compression. After the cover plate body is fully installed with the cable tray body, multiple locking members arranged in the cover plate body are driven by the elastic triggers and inserted into the limiting groove formed by the cable tray body.

[0008] The cover plate locking structure described above has multiple recessed grooves formed within the cover plate body, and the elastic trigger is disposed within the recessed grooves.

[0009] The cover plate locking structure described above: the elastic trigger includes a support plate installed in the inner groove, and a hinge shaft rotatably connected to the cover plate body is rotatably mounted on one end of the support plate away from the side wall of the inner groove. A pressing plate is mounted on the hinge shaft.

[0010] It also includes a spring, one end of which is hinged to the support plate and the other end of which is hinged to the extrusion plate.

[0011] As described above, the cover plate locking structure has abutment blocks symmetrically arranged at both ends of the support plate to limit the movement of the extrusion plate.

[0012] The cover plate locking structure described above: the locking member includes a sleeve arranged axially along the hinge axis, the sleeve is rotatably connected to the cover plate body, and a locking rod is fixedly connected to the sleeve, with a V-shaped block adapted to the limiting groove formed at the end of the locking rod away from the sleeve.

[0013] As described above, the cover plate locking structure has multiple arc-shaped blocks arranged along the circumference of the hinge shaft, and an arc-shaped groove that rotates and engages with the arc-shaped groove is formed inside the sleeve.

[0014] As described above, the cover plate locking structure includes a damping sleeve at the connection between the sleeve and the cover plate body.

[0015] A pallet cable tray, comprising the cover locking structure described in any one of the above claims.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] By manually controlling the cover plate body to align and close with the cable tray body, the elastic trigger on the cover plate body deforms under the pressure of the side wall of the cable tray body. After the cover plate body and the cable tray body are fully closed, the elastic trigger can burst out instantly under the action of the stored elastic force, quickly driving the locking part to rotate into the limit groove, so as to realize the rapid locking of the cover plate body and the cable tray body. Moreover, no auxiliary tools are needed for installation. Furthermore, by controlling the cable tray body and the cover plate body to align and close, a stable connection between the cover plate body and the cable tray body can be guaranteed.

[0025] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0026] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0027] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0028] Please see Figures 1-6 In this embodiment of the utility model, a cover plate locking structure includes a cable tray body 1 and a cover plate body 2 that can be detached and installed from the cable tray body 1.

[0029] At least one set of elastic triggering elements are symmetrically arranged at both ends of the inner side of the cover plate body 2. When the cover plate body 2 is installed, the elastic triggering elements are squeezed and deformed. After the cover plate body 2 is fully installed with the cable tray body 1, multiple locking elements arranged in the cover plate body 2 are driven by the elastic triggering elements and inserted into the limiting groove 101 formed by the cable tray body 1.

[0030] In detail, when the cable tray body 1 and the cover plate body 2 are assembled, the cover plate body 2 is manually aligned with the cable tray body 1 and closed. The elastic trigger on the cover plate body 2 is deformed by the pressure of the side wall of the cable tray body 1. After the cover plate body 2 and the cable tray body 1 are fully closed, the elastic trigger can burst out instantly under the action of the stored elastic force, quickly driving the locking part to rotate into the limit groove 101, so as to realize the rapid locking of the cover plate body 2 and the cable tray body 1. Moreover, no auxiliary tools are needed for installation. And by controlling the alignment of the cable tray body 1 and the cover plate body 2 and closing them, the stable connection between the cover plate body 2 and the cable tray body 1 can be guaranteed.

[0031] Preferably, the cover plate body 2 has a plurality of embedded grooves 201 formed therein, and the elastic trigger is disposed in the embedded grooves 201.

[0032] For further solutions to this utility model, please refer to [link / reference]. Figure 4 and Figure 5 The elastic trigger includes a support plate 7 installed in the inner groove 201. The end of the support plate 7 away from the side wall of the inner groove 201 is rotatably mounted with a hinge shaft 3 that is rotatably connected to the cover plate body 2. A pressing plate 6 is installed on the hinge shaft 3.

[0033] It also includes a spring 9, one end of which is hinged to the support plate 7 and the other end of which is hinged to the compression plate 6.

[0034] Preferably, the support plate 7 is provided with abutment blocks 8 at both ends to limit the compression plate 6.

[0035] In the initial state, spring 9 is in a stretched state. At this time, the stretch of spring 9 is at its minimum value. Spring 9 generates a counterclockwise rotational force on the extrusion plate 6. Under the restriction of the abutment block 8, the extrusion plate 6 cannot rotate counterclockwise. However, under the drive of an external force and the external force being greater than the elastic potential energy of spring 9, the requirement for the extrusion plate 6 to rotate clockwise can be achieved.

[0036] The cover plate body 2 is manually aligned and closed with the cable tray body 1. During the closing process, the pressing plate 6 is squeezed by the cable tray body 1 and rotates clockwise, causing the spring 9 to continue to stretch, and the elastic potential energy gradually increases until the pressing plate 6 and the support plate 7 are on the same horizontal line. At this time, the stretch of the spring 9 is at its maximum value, and the pressing plate 6 and the support plate 7 are in force balance. However, the cover plate body 2 and the cable tray body 1 are not completely closed. After moving down a small distance to achieve a complete fit between the cover plate body 2 and the cable tray body 1, the pressing plate 6 is pressed again, and the balance between it and the support plate 7 is released. Under the elastic action of the spring 9, it rotates rapidly. When the pressing plate 6 deflects, it drives the hinge shaft 3 to deflect synchronously. During the rotation of the pressing plate 6, and after the balance between the pressing plate 6 and the support plate 7 is released, the rotation can drive the locking device to lock the cable tray body 1.

[0037] For further solutions to this utility model, please refer to [link / reference]. Figure 6 The locking component includes a sleeve 4 arranged axially along the hinge axis 3. The sleeve 4 is rotatably connected to the cover plate body 2, and a locking rod 5 is fixedly connected to the sleeve 4. A V-shaped block 501 adapted to the limiting groove 101 is formed at one end of the locking rod 5 away from the sleeve 4.

[0038] Multiple arc-shaped blocks 301 are arranged along the circumference of the hinge shaft 3, and an arc-shaped groove 401 is formed inside the sleeve 4 to rotate and cooperate with the arc-shaped blocks 301.

[0039] Specifically, when the hinge shaft 3 deflects, the arc block 301 and the side wall of the arc groove 401 are not in contact, so the rotation of the hinge shaft 3 does not affect the sleeve 4. When the extrusion plate 6 rotates to be on the same horizontal line as the support plate 7, the arc block 301 and the side wall of the arc groove 401 are in contact. After that, when the cover plate body 2 and the cable tray body 1 are fully closed, the extrusion plate 6 deflects rapidly under the action of the spring 9. At this time, the rotation of the hinge shaft 3 can drive the sleeve 4 to rotate, so that the locking rod 5 deflects synchronously. The V-block 501 rotates into the limiting groove 101 and engages with the limiting groove 101 to lock the cable tray body 1 and ensure the stable connection between the cable tray body 1 and the cover plate body 2.

[0040] Preferably, a damping sleeve is provided at the connection between the sleeve 4 and the cover plate body 2. The damping sleeve is mainly provided to prevent the hinge shaft 3 from rotating in the opposite direction when the cover plate body 2 and the cable tray body 1 are not installed, so as to avoid affecting the sleeve 4 and thus affecting the subsequent engagement of the V-block 501 and the limiting groove 101.

[0041] A pallet bridge includes the cover locking structure described in any one of the above claims.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
