Description

Technical Field

[0001] The utility model relates to the field of power switch boxes, in particular to a dust cover device for a power switch box. Background Art

[0002] The power switch box is usually provided with a socket for connecting electrical appliances. When the power switch box is not connected to a plug, a cover or plug is generally used to seal the socket to ensure waterproof and dustproof performance, thereby preventing water stains or dust from entering the power switch box. Existing covers are either independent or hinged to the power switch box. Among them, the independent cover is easy to lose during use and is gradually being eliminated. Although the cover hinged to the power switch box is not easy to lose, it has unreliable sealing, short service life and inconvenient assembly during actual use. In order to solve the above problems, a dust cover device for the power switch box is proposed. Utility Model Content

[0024] The present invention is described in further detail below with reference to the accompanying drawings.

[0025] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention as defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

Therefore, the above terms should not be understood as limitations on the present invention.

[0027] As attached Figure 1-5 The dust cover device of a power switch box shown in the figure comprises: a switch box body 1, a dust cover 2 and a driving member. The switch box body 1 is provided with a socket position 1.1 for conveniently plugging in an electrical plug, and the dust cover 2 is hinged to the switch box body 1 to seal the socket position 1.1. The driving member can be embedded in the dust cover 2 or in the switch box body 1 to provide a driving force for the dust cover 2 so that the dust cover 2 is pressed tightly against the switch box body 1. The dust cover 2 can seal the socket position 1.1 on the switch box body 1, and the driving member can further ensure the reliability of the seal to avoid opening. The driving member embedded in the dust cover 2 effectively improves the assembly efficiency and can reduce the influence of external debris on the driving member, thereby improving the reliability of use and extending the service life.

[0028] To ensure the reliable hinged connection between the dust cover 2 and the switch box body 1, hinged portions 2.1 are provided at each end of one side of the dust cover 2. The switch box body 1 is equipped with fixed columns 1.3 that rotatably engage with the corresponding hinged portions 2.1. Specifically, the switch box body 1 is provided with mounting bosses 1.2 on either side of the dust cover 2. The fixed columns 1.3 are integrally fixed to the corresponding mounting bosses 1.2. The provided mounting bosses 1.2 ensure the reliable rotation of the dust cover 2, preventing interference with the switch cover body. They also limit the lateral movement of the dust cover 2, ensuring practical reliability. It is worth noting that the two hinged portions can be integrally formed on one side of the dust cover.

[0029] The present invention is described by taking the example of a driving member embedded in the dust cover 2: on the basis of the above, one of the two hinged parts 2.1 is provided with a hinge hole 2.2, the fixing column 1.3 is inserted into the corresponding hinge hole 2.2, and the driving member is arranged in the hinge hole 2.2. Specifically, the driving member is a compression torsion spring 3, as shown in the attached figure. Figure 5As shown, the fixing column 1.3 is provided with a first slot 1.4, one end of the compression torsion spring is embedded in the first slot 1.4, and the other end of the compression torsion spring 3 is embedded in the hinge hole 2.2. The provision of the first slot 1.4 ensures the reliable cooperation between the compression torsion spring and the fixing column 1.3, and the compression torsion spring ensures the driving force when the dust cover 2 rotates, as well as the pressing force on the insertion hole 1.1. Further, the side wall of the hinge hole 2.2 is provided with a limiting gap 2.3 along its length, and the other end of the compression torsion spring is embedded in the limiting gap 2.3. The limiting gap 2.3 improves assembly convenience, that is, the other end of the compression torsion spring can be directly fixed in the limiting gap 2.3.

[0030] It is worth mentioning that a limiting bayonet 2.4 is provided at one end of the limiting gap 2.3 away from the fixing column 1.3. The limiting bayonet 2.4 is staggered with the limiting gap 2.3, and the other end of the compression torsion spring 3 is embedded in the limiting bayonet 2.4. The setting of the limiting bayonet 2.4 can ensure that there is a reliable pressing force between the dust cover 2 and the switch box body 1 in the initial state, thereby ensuring the sealing of the switch box body 1 in the initial state.

[0031] In order to improve the efficiency of assembly, a clamping groove 2.5 is provided on the other hinge part 2.1. The opening of the clamping groove 2.5 is retracted inward. After the end with the driving member is assembled, the hinge part 2.1 is pressed hard so that the fixing column 1.3 is clamped into the clamping groove 2.5 to complete the assembly, simplifying the assembly steps.

[0032] To further enhance dustproof performance, a sealing groove 2.6 is provided inside the dust cover 2, within which a sealing gasket 4 is embedded. This groove 2.6 also acts as a buffer, reducing the possibility of collision between the dust cover 2 and the switch box body 1. Preferably, a sealing collar 1.5 is provided around the circumference of the socket 1.1 on the switch box body 1. This collar 1.5 is aligned with the sealing gasket 4. The cooperation between the sealing collar 1.5 and the sealing gasket 4 further enhances water and dustproof performance, preventing water from entering the socket 1.1 along the upper side of the switch box.

[0033] It is worth noting that the arrangement of the driving member may also be modified in other ways. For example, the fixing column 1.3 may have a mounting hole formed along its axial direction, the compression torsion spring may be embedded in the mounting hole, the hinge portion 2.1 of the dust cover 2 may be provided with a hinge shaft inserted into the mounting hole, and the ends of the compression torsion spring may be engaged with the fixing column 1.3 and the hinge shaft. The driving member is a compression torsion spring, which may of course be replaced by a coil spring or a torsion bar.

[0034] Those skilled in the art will appreciate that the embodiments of the present invention described above and shown in the accompanying drawings are intended only as examples and do not limit the present invention. The objectives of the present invention have been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and illustrated in the embodiments. Any variations or modifications may be made to the embodiments of the present invention without departing from the principles described.
