[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figures 1-6 As shown, the utility model provides the following technical solutions:

[0023] A push button switch includes a housing 1, with a detachable switch member 4 and a pressing member 3 connected to the top and bottom of the housing 1, respectively. The switch member 4 includes a second inner housing 41 and a switch portion mounted inside the second inner housing 41 for connecting to a wire. The pressing member 3 includes a first inner housing 31 and a pressing portion that moves up and down relative to the first inner housing 31. The pressing portion presses the switch portion to open or close the circuit.

[0024] The first inner shell 31 and the second inner shell 41 are screwed together at the top and bottom of the housing 1 respectively.

[0025] Through the above technical solution, when personnel need to use the device, the shell part 1 is fixed at the position required by the personnel, and then the wires to be connected are connected to the switch part. By pressing the switch part, the switch part squeezes the switch part, thereby allowing the switch part to pass, and then the wires are conductive. Then, the switch part is pressed to disconnect the switch part, thereby disconnecting the wires. When personnel need to inspect the device, the first inner shell 31 and the second inner shell 41 are rotated to separate the first inner shell 31 and the second inner shell 41 from the shell part 1, thereby moving the switch part and the pressing part to the outside of the shell part 1, so that personnel can easily inspect the device.

[0026] In order to facilitate the installation of the device, in the present invention, Figures 1-4 As shown, a movable positioning member 2 is screwedly connected to the outer circumference of the housing member 1 , and the positioning member 2 includes a connecting ring 21 , and a connecting groove 22 matching the housing member 1 is formed on the connecting ring 21 .

[0027] In this embodiment, when a person needs to fix the shell part 1, the connecting ring 21 is screwed into the shell part 1 through the connecting groove 22, and then the connecting ring 21 is rotated to adjust the position of the connecting ring 21 on the shell part 1, and the connecting ring 21 is fixed to fix the position of the shell part 1.

[0028] Furthermore, in order to further increase the scope of use of the device, e.g. Figure 1-Figure 3 As shown, two bottom plates 28 are symmetrically fixedly connected to the bottom of the connecting ring 21, and the opposite sides of the two bottom plates 28 are recessed to form a first connecting hole 26, and an extension plate 23 is provided on one side of the two bottom plates 28. A connecting rod 25 matching the first connecting hole 26 is fixedly connected to one side of the extension plate 23, and the other side is recessed to form a second connecting hole 27 matching the connecting rod 25. A flame retardant rubber plate 24 is bonded to the top of the extension plate 23.

[0029] In this embodiment, when a person is in front of the fixing device, he / she takes the extension plates 23 of the number required by the person, and then screws the extension plates 23 to the second connecting holes 27 on another extension plate 23 through the connecting rod 25, so that the extension plates 23 of the number required by the person are connected, and then screws the adjusted extension plates 23 to the first connecting holes 26 on the base plate 28 through the connecting rod 25, so that the extension plates 23 are fixed on both sides of the base plate 28, and then fixes the connecting ring 21 to the position required by the person, and limits the connecting ring 21 through the extension plate 23, so as to support the shell member 1.

[0030] Specifically, in one embodiment, regarding the housing 1:

[0031] like Figure 1-Figure 2 、 Figure 4-Figure 6As shown, the shell 1 includes an outer shell 11 , which has a through inner cavity 12 along its own axis. A spacer ring 13 is fixedly connected to the inner cavity 12 , and the first inner shell 31 and the second inner shell 41 are located above and below the spacer ring 13 .

[0032] In this embodiment, the outer shell 11 is screwed together with the first inner shell 31 and the second inner shell 41 so that the first inner shell 31 and the second inner shell 41 are installed inside the inner cavity 12, and the first inner shell 31 and the second inner shell 41 are limited by the spacer ring 13.

[0033] In addition, in the present invention, regarding the above-mentioned switch part:

[0034] like Figure 1-Figure 2 、 Figure 4-Figure 6 As shown, the switch part includes a circuit board 42, which is fixedly connected to the inside of the second inner shell 41, and two electrodes 44 for connecting wires are symmetrically fixedly connected to the bottom of the circuit board 42, and a detachable screw 45 is screwed on one side of the electrode 44, and a reset head 43 is installed on the top of the circuit board 42.

[0035] In this embodiment, when the device needs to be used, the wire is connected to the electrode 44, and then the screw 45 is screwed together with the electrode 44 to fix the wire. The reset head 43 is squeezed by the pressing part to make the wire connected, and the reset head 43 is squeezed by the pressing part again to disconnect the wire.

[0036] In addition, in the present invention, regarding the above-mentioned pressing portion:

[0037] like Figure 1-Figure 2 、 Figure 4-Figure 6 As shown, the pressing part includes a pressing plate 34, which is located inside the first inner shell 31, and two side plates 36 are symmetrically installed inside the first inner shell 31. A spring 35 is fixedly connected between the bottom of the side plate 36 and the top of the pressing plate 34, and a bottom rod 33 is fixedly connected to the top of the pressing plate 34, and a pressing head 32 is fixedly connected to the top of the bottom rod 33.

[0038] In this embodiment, when it is necessary to press the reset head 43, the pressing head 32 is pressed, so that the pressing head 32 drives the bottom rod 33 to move, and the bottom rod 33 drives the pressure plate 34 to move. When the pressure plate 34 moves, the spring 35 is stretched. After the pressure plate 34 squeezes the reset head 43, the pressing head 32 is released, and the pressure plate 34 is pulled by the spring 35 to move the pressure plate 34 back to its original position.

[0039] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
