Description

Technical Field

[0001] The utility model belongs to the technical field of electronic component switches, in particular to an electronic component switch with a dustproof function. Background Art

[0002] An electronic switch refers to an operating unit that uses electronic circuits and power electronic devices to realize circuit switching, and includes at least one controllable electronic driver. Existing electronic component switches generally use protective covers to protect them from dust due to their wide contact surface. However, when the protective covers are opened, they are generally opened by removing bolts. This method not only has cumbersome operating steps, but also makes it difficult to disassemble when inspecting and repairing the electronic component switches, which can easily affect the inspection efficiency of maintenance personnel. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the utility model provides an electronic component switch with a dustproof function, which solves the problem that the operation steps are cumbersome due to removing bolts to open the protective cover, and the inconvenience of disassembly also easily affects the inspection efficiency of maintenance personnel when inspecting and repairing the electronic component switch.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an electronic component switch with dustproof function, comprising a switch body, four limit grooves are provided on the side of the switch body, a moving mechanism is connected to the side of the switch body, the moving mechanism comprises a fixed sleeve, the fixed sleeve is connected to the outside of the switch body, a threaded rod is rotatably connected inside the fixed sleeve, a moving block is externally threadedly connected to the threaded rod, the moving block is hinged to two rotating rods through two pins, and the two rotating rods are respectively hinged to support blocks through two pins;

[0005] The support block is connected with a protective cover, the upper and lower parts of the protective cover are connected with connecting rods, and one end of the connecting rod is connected with a dovetail block.

[0006] As a further solution of the utility model: the dovetail block is slidably connected in the limiting groove, and a sealing groove is provided on the side of the protective cover located on the left side.

[0007] As a further solution of the utility model: a handle is provided at the bottom end of the threaded rod, and a sealing strip is connected to the side of the protective cover located on the right side.

[0008] As a further solution of the utility model: the sealing strip is slidably connected in the sealing groove, and four air holes are opened in the protective cover.

[0009] As a further solution of the utility model: a filter screen is provided in the air vent, and the shape of the connecting rod is L-shaped.

[0010] As a further solution of the utility model: an indicator light is arranged outside the switch body, and a groove is arranged inside the switch body.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The electronic component switch with dustproof function is provided with a switch body, a limit groove, a moving mechanism and a handle. When the handle drives the threaded rod to rotate, the moving block moves upward outside the threaded rod and pushes the two rotating rods to open relatively, thereby pushing the two supporting blocks and the protective cover to move relatively, so that the corresponding two connecting rods and the dovetail block move synchronously, so that the device can quickly open the protective cover, avoiding the cumbersome operation steps caused by removing the bolts to open the protective cover, facilitating maintenance personnel to carry out inspection and maintenance, and ensuring the maintenance personnel's inspection efficiency.

[0013] 2. The electronic component switch with dustproof function is provided with a sealing groove, a sealing strip, an air vent and a filter. When the two protective covers are closed to each other, the sealing strip can be inserted into the sealing groove to further block external dust, and the internal electronic component switch can dissipate heat through the air vent, and the filter can prevent dust from the air vent, thereby ensuring the dustproof effect of the device.

DETAILED DESCRIPTION

[0019] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0020] like Figure 1-4As shown, the utility model provides a technical solution: an electronic component switch with dustproof function, comprising a switch body 1, an indicator light is arranged outside the switch body 1, a groove is arranged inside the switch body 1, and four limit grooves 2 are arranged on the side of the switch body 1. By setting the limit grooves 2, and the mutual cooperation between the limit grooves 2 and the dovetail block 308, the dovetail block 308 can be prevented from being offset and stuck when moving, thereby ensuring the stable movement of the dovetail block 308;

[0021] The side of the switch body 1 is connected with a moving mechanism 3, and the moving mechanism 3 includes a fixing sleeve 301. By setting the fixing sleeve 301, the fixing sleeve 301 can support the threaded rod 302, so as to avoid the threaded rod 302 from being offset and stuck when rotating, thereby ensuring the stable rotation of the threaded rod 302.

[0022] The fixing sleeve 301 is connected to the outside of the switch body 1, and a threaded rod 302 is rotatably connected inside the fixing sleeve 301. The threaded rod 302 is externally threadedly connected to a moving block 303. The moving block 303 is hinged to two rotating rods 304 through two pins. The two rotating rods 304 are respectively hinged to support blocks 305 through two pins. A protective cover 306 is connected to the support block 305. The protective cover 306 is connected to connecting rods 307 at the top and bottom. By providing the connecting rod 307, the connecting rod 307 can support the dovetail block 308 to prevent the dovetail block 308 from deviating and falling when moving, thereby ensuring the stable movement of the dovetail block 308.

[0023] One end of the connecting rod 307 is connected with a dovetail block 308, which is slidably connected in the limiting groove 2. A sealing groove 4 is provided on the side of the protective cover 306 on the left side, a handle 5 is provided at the bottom end of the threaded rod 302, and a sealing strip 6 is connected to the side of the protective cover 306 on the right side. By providing the sealing strip 6, the sealing strip 6 and the sealing groove 4 cooperate with each other, which can not only guide the protective cover 306, but also block dust.

[0024] The sealing strip 6 is slidably connected in the sealing groove 4. Four air holes 7 are provided in the protective cover 306. A filter screen 8 is provided in the air holes 7. The connecting rod 307 is L-shaped.

[0025] The working principle of the utility model is:

[0026] When using the device, when the switch body 1 needs to be inspected, the handle 5 is turned, and the handle 5 drives the threaded rod 302 to rotate, thereby driving the movable block 303 to move upward outside the threaded rod 302, thereby pushing the two rotating rods 304 to open relative to each other, and then driving the two supporting blocks 305 and the protective cover 306 to move relative to each other, and driving the corresponding two connecting rods 307 and the dovetail block 308 to move relative to each other in the limit groove 2, so that the sealing strip 6 and the sealing groove 4 are separated from each other. When the inspection is completed, the handle 5 can be turned in the opposite direction.

[0027] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0028] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
