Description

Technical Field

[0001] The invention relates to the technical field of switches, in particular to a dustproof rocker switch. Background Art

[0002] At present, the rocker switches used in the control parts of power tools, garden tools, machine tools and hardware tools all adopt a structure in which one end of the special-shaped terminal is riveted to the inside of the metal part, and the other end is exposed to connect to the power cord. The internal riveting process of this structure is difficult to control, which is prone to poor connection or unreliable riveting; in addition, due to the influence of the product structure, the end of the switch exposed to the power cord can only be fixed with M3 screws, which makes the switch prone to unstable connection during operation vibration, generating electric sparks, affecting the stability of the operation, and thus affecting the overall service life of the product. Therefore, technicians in this field urgently need to develop a rocker switch with a relatively stable structure and simple assembly process. Summary of the invention

[0003] The object of the present invention is to provide a dustproof rocker switch to solve the problems raised in the above background technology.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] A dustproof rocker switch comprises a main body base and a handle. The main body base is composed of a base group and an upper cover group. The base group comprises a base, a conjoined static contact piece, a rocker, a conjoined support frame, a nut and a washer screw. The nut and the washer screw are fixedly installed at the bottom of the front of the base. The conjoined static contact piece, the rocker and the conjoined support frame are all built inside the base. The bottom of the conjoined static contact piece and the conjoined support frame is fixedly connected to the base. The top of the base is installed with an upper cover group. The upper cover group consists of a push shaft spring, a dustproof ring, a push shaft, a bullet head, a bullet head spring, an upper cover, a lock button, a lock button spring and a card. The upper cover is installed on the top of the main body base. Buckles are arranged on both sides of the upper cover. A convex wall is also arranged on the upper cover. The bottom of the upper cover is movably connected to the top of the push shaft, and the top of the push shaft extends to the top of the base. The top of the top of the push shaft is connected to the upper cover through the push shaft spring. The bottom of the bullet head is connected to the lower end of the push shaft through the bullet head spring, and the bullet head is located above the rocker. The lock button is connected to the left side of the upper cover, and a lock button spring and a card are installed between the lock button and the left upper cover.

[0006] Furthermore, a groove is provided on the edge of the base, and a hook is provided on the top of the base, and the hook matches with a buckle on the upper cover.

[0007] Furthermore, the nut and the washer screw cooperate with each other and the number of the nut and the number of the washer screw are both 4.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] 1. The internal structure adopts a metal actuator and an external wiring part, which expands the exposed wiring part and increases the matching screws, reduces the riveting process, avoids the loosening of the power cord due to working vibration, effectively improves production efficiency and product quality stability, makes the wiring more firm and reliable, and has broad market application prospects.

[0010] 2. By setting grooves and convex walls on the base and the upper cover, it can better prevent dust. The base and the upper cover are equipped with four pairs of hooks that are perfectly combined together for easy installation and disassembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] See also Figure 1-6 , the present invention provides a technical solution:

[0021] A dustproof rocker switch includes a main body base and a handle 20. The main body base is composed of a base group and an upper cover group. The base group includes a base 1, a conjoined static contact piece 2, a rocker 3, a conjoined support frame 4, a nut 5 and a washer screw 6. The nut 5 and the washer screw 6 are fixedly installed at the bottom of the front of the base 1. The conjoined static contact piece 2, the rocker 3 and the conjoined support frame 4 are all built into the base 1. The bottoms of the conjoined static contact piece 2 and the conjoined support frame 4 are fixedly connected to the base 1. The top of the base 1 is installed with an upper cover group. The upper cover group is composed of a push shaft spring 7, a dustproof ring 8, a push shaft 9, a bullet head 11, a bullet head spring 10, an upper cover 12, a lock button 13, a lock button spring 14 and a card 15. The upper cover 12 is installed on the top of the main body base. Buckles 19 are provided on both sides of the upper cover 12. A convex wall 17 is also provided on the upper cover 12. The bottom of the upper cover 12 is movably connected to the top of the push shaft 9, and the top of the push shaft 9 extends to the top of the base 1. The top of the push shaft 9 is connected to the upper cover 12 through the push shaft spring 7. The bottom of the bullet head 11 is connected to the lower end of the push shaft 9 through the bullet head spring 10, and the bullet head 11 is located above the rocker 3.

The nut 5 cooperates with the washer screw 6, and the number of the nut 5 and the washer screw 6 is 4.

[0022] Working principle:

[0023] like Figures 1 to 6As shown, a dustproof rocker switch includes a main body base and a handle 20. The main body base is composed of a base group and an upper cover group. The base group includes a base 1, a conjoined static contact piece 2, a rocker 3, a conjoined support frame 4, a nut 5 and a washer screw 6. Among them, a groove 16 and four hooks 18 are provided on the base 1. The upper cover group is composed of a push shaft spring 7, a dustproof ring 8, a push shaft 9, a bullet head 11, a bullet head spring 10, an upper cover 12, a lock button 13, a lock button spring 14 and a card 15. Among them, a convex wall 17 and four buckles 19 are provided on the upper cover 12. First, install four nuts 5, two integrated static contact pieces 2 together with two integrated support frames 4 to the designated positions of the base 1, fix them with four screws 6 with washers, and then install the two rockers 3 to the designated positions of the base 1; take the upper cover 12 and install the lock button 13, lock button spring 14 and card 15 to the designated position of the upper cover 12; after installing the dust ring 8 to the designated position of the push shaft 9, install the bullet spring 10 and the bullet head 11 to the designated positions of the push shaft 9 respectively; install the installed push shaft 9 to the upper cover 12, and then install the installed upper cover 12 to the base 1, wherein the groove 16 on the base 1 and the convex wall 17 on the upper cover 12, the four hooks 18 of the base 1 and the four buckles 19 of the upper cover 12 are tightly combined, and finally install the handle 20. The integrated static contact piece 2, the rocker plate 3 and the upper cover group in the base 1 solve the problems of poor control of the traditional riveting process and loosening due to working vibration. By arranging grooves 16 and convex walls 17 on the base 1 and the upper cover 12, the dustproof effect can be better achieved. The base 1 and the upper cover 12 are provided with four pairs of hooks 18 and buckles 19 that are perfectly combined together for easy installation and disassembly.
