Description

Technical Field

[0001] The utility model relates to the technical field of phase change switches, in particular to a phase change switch with a protection function. Background Technique

[0002] A phase change switch generally refers to a device in the electrical field, which is used to control the start, stop and reverse of a motor. Its function is to change the wiring of the motor according to needs, so as to change the running direction of the motor. A phase change switch usually includes a set of contacts or switches, which can switch the wiring of the motor according to the operator's instructions, so that the motor can rotate forward, reverse or stop.

[0003] The existing phase change switch is not provided with a protection mechanism on the outside. When it is impacted by an external force, the phase change switch is easily damaged by the impact, thus affecting the operation of the staff. Therefore, we propose a phase change switch with a protection function to solve the above problems. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a phase change switch with a protection function to solve the above problems.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A phase change switch with a protection function includes a phase change switch body. An outer frame is fixedly installed on the outer side wall of the phase change switch body. A protective cover is movably sleeved on the outer side wall of the outer frame. A plurality of installation grooves are respectively opened on the outer side wall of the outer frame. Elastic buffer mechanisms for the protective cover are arranged in the plurality of installation grooves. An activity groove is opened on the inner wall of the protective cover. A transparent acrylic plate is movably sleeved in the activity groove.

[0007] Preferably, the number of the installation grooves is four, and the four installation grooves are respectively located on the outer side walls of the four sides of the outer frame, which is convenient for the stability of the connection between the elastic buffer mechanisms in the four installation grooves and the protective cover.

[0008] Preferably, the elastic buffer mechanism includes a mounting plate and a spring. The mounting plate is movably installed in the installation groove. One end of the spring is fixedly installed on one side of the mounting plate, and the other end of the spring is fixedly installed on one side inner wall of the installation groove. One side of the mounting plate is fixedly connected with one side inner wall of the protective cover. The outer frame and the protective cover are connected by four groups of elastic buffer mechanisms, which can buffer and absorb the impact force of the impact.

[0009] Preferably, a frame plate is fixedly installed on the top side of the transparent acrylic plate, and the bottom side wall of the frame plate is attached to the top side of the protective cover. Even when the protective cover and the transparent acrylic plate are impacted on the outer side wall of the outer frame and move to the maximum distance, the inner side wall of the transparent acrylic plate will not contact the rotary switch on the phase change switch body.

[0010] Preferably, a rotary switch is provided on one side of the phase change switch body, and a plurality of circumferentially distributed scale marks are provided on one side of the phase change switch body. By screwing the rotary switch on the phase change switch body, the operation of the phase change switch body can be realized.

[0011] Preferably, a side plate is fixedly installed on one side of the transparent acrylic plate, and the side plate on the transparent acrylic plate is located on the side away from the rotary switch. The staff can easily realize the lifting and moving adjustment of the transparent acrylic plate by lifting the side plate on one side of the transparent acrylic plate, and at the same time, it also prevents the transparent acrylic plate from sliding out of the movable groove.

[0012] Compared with the prior art, the beneficial effects of the present utility model are:

[0013] For the phase change switch with a protection function, an outer frame is provided on the outer side of the phase change switch body, and the outer side wall of the outer frame is movably sleeved with a protective cover through four groups of elastic buffer mechanisms. The port of the protective cover is movably inserted with a transparent acrylic plate. It is convenient for the staff to lift the side plate on one side of the transparent acrylic plate, drive the transparent acrylic plate to move upward in the movable groove, and make the transparent acrylic plate unfold an opening on the port of the protective cover, so as to facilitate the staff to operate the rotary switch of the phase change switch body.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0020] Refer to Figures 1-4 , a commutation switch with a protection function includes a commutation switch body 1. An outer frame 2 is fixedly installed on the outer side wall of the commutation switch body 1. A protective cover 6 is movably sleeved on the outer side wall of the outer frame 2. A plurality of installation grooves 3 are respectively formed on the outer side wall of the outer frame 2. A elastic buffer mechanism for the protective cover 6 is arranged in each of the plurality of installation grooves 3. An activity groove 7 is formed on the inner wall of the protective cover 6. A transparent acrylic plate 8 is movably sleeved in the activity groove 7.

[0021] Furthermore, the number of the installation grooves 3 is set to four, and the four installation grooves 3 are respectively located on the outer side walls of the four sides of the outer frame 2, which is convenient for the stability of the connection between the elastic buffer mechanisms in the four installation grooves 3 and the protective cover 6.

[0022] Specifically, the elastic buffer mechanism includes a mounting plate 4 and a spring 5. The mounting plate 4 is movably installed in the installation groove 3. One end of the spring 5 is fixedly installed on one side of the mounting plate 4, and the other end of the spring 5 is fixedly installed on one side inner wall of the installation groove 3. One side of the mounting plate 4 is fixedly connected to one side inner wall of the protective cover 6. The outer frame 2 and the protective cover 6 are connected by four groups of elastic buffer mechanisms, which can buffer and absorb the impact force of the impact.

[0023] Specifically, a border plate 9 is fixedly installed on the top side of the transparent acrylic plate 8, and the bottom side wall of the border plate 9 is attached to the top side of the protective cover 6. Even when the protective cover 6 and the transparent acrylic plate 8 are impacted on the outer side wall of the outer frame 2 and move to the maximum distance, the inner side wall of the transparent acrylic plate 8 will not contact the knob switch 11 on the commutation switch body 1.

[0024] Specifically, a knob switch 11 is arranged on one side of the commutation switch body 1. A plurality of circumferentially distributed scale marks are arranged on one side of the commutation switch body 1. By screwing the knob switch 11 on the commutation switch body 1, the operation of the commutation switch body 1 is realized.

[0025] Specifically, a side plate 10 is fixedly installed on one side of the transparent acrylic plate 8. The side plate 10 on the transparent acrylic plate 8 is located on the side away from the knob switch 11. By lifting the side plate 10 on one side of the transparent acrylic plate 8, the staff can easily achieve the lifting and adjusting movement of the transparent acrylic plate 8, and at the same time prevent the transparent acrylic plate 8 from sliding out of the moving slot 7.

[0026] During use: When an external force impacts the phase change switch body 1, the protective cover 6 and the transparent acrylic plate 8 play a protective role for the phase change switch body 1, causing the four mounting plates 4 on the inner wall of the protective cover 6 driven by the transparent acrylic plate 8 to slide in the corresponding mounting slots 3, deforming and compressing the four springs 5. The impact force of the impact is buffered and absorbed through the four springs 5, thus avoiding damage to the phase change switch body 1 caused by the impact. Even when the protective cover 6 and the transparent acrylic plate 8 are impacted and moved to the maximum distance on the outer side wall of the outer frame 2, the inner side wall of the transparent acrylic plate 8 will not come into contact with the knob switch 11 on the phase change switch body 1; when the staff operates the phase change switch body 1, by lifting the side plate 10 on one side of the transparent acrylic plate 8, the transparent acrylic plate 8 is driven to move upward in the moving slot 7, causing the transparent acrylic plate 8 to open an opening at the port of the protective cover 6, facilitating the staff to operate the knob switch 11 of the phase change switch body 1.

[0027] In summary, in the method of this case, an outer frame 2 is provided on the outer side of the phase change switch body 1. The outer side wall of the outer frame 2 is movably sleeved with a protective cover 6 through four groups of elastic buffer mechanisms. The port of the protective cover 6 is movably inserted with a transparent acrylic plate 8, facilitating the staff to lift the side plate 10 on one side of the transparent acrylic plate 8, driving the transparent acrylic plate 8 to move upward in the moving slot 7, causing the transparent acrylic plate 8 to open an opening at the port of the protective cover 6, facilitating the staff to operate the knob switch 11 of the phase change switch body 1. The protective cover 6 and the transparent acrylic plate 8 cooperate to play a protective role for the phase change switch body 1, avoiding damage to the phase change switch body 1 caused by impact.
