[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 Figure 1-5 , an embodiment provided by the utility model:

[0023] An electric switch for a fracturing device: comprising an electric switch body 1, a push-type switch button 11 is provided on the surface of the electric switch body 1, a wireless signal module 12 is provided on the top of the electric switch body 1, an anti-accidental touch mechanism is provided on the surface of the electric switch body 1, and the anti-accidental touch mechanism comprises a protective frame 2, the protective frame 2 is fixedly connected to the surface of the electric switch body 1, a protective plate 21 is slidably connected to the surface of the protective frame 2, a bottom plate 22 is fixedly connected to the surface of the protective plate 21, and a fixing plate 2 is fixedly connected to the bottom of the protective frame 2 3. A spring 24 is fixedly connected to the surface of the fixing plate 23, and one end of the spring 24 away from the fixing plate 23 is fixedly connected to the surface of the bottom plate 22. A limit plate 25 is fixedly connected to the surface of the electric control switch body 1. The anti-accidental touch mechanism requires the operator to move the protective plate 21 out from the front of the push-type switch button 11 in advance before pressing the push-type switch button 11, so that the fracturing device can be detonated, thereby avoiding the operator from accidentally touching the push-type switch button 11, preventing the fracturing device from accidentally exploding, and improving the safety of the fracturing device during use.

[0024] Furthermore, a protective mechanism is provided on the top of the electric switch body 1, which includes a fixed block 3, which is fixedly connected to the top of the electric switch body 1, a two-way screw rod 31 is rotatably connected to the surface of the fixed block 3, a knob 32 is fixedly connected to the surface of the two-way screw rod 31, a square nut 33 is threadedly connected to the surface of the two-way screw rod 31, a protective cover 34 is fixedly connected to the surface of the square nut 33, and the protective cover 34 is slidably connected to the surface of the electric switch body 1. For the stability of signal transmission, the wireless signal module 12 is usually arranged outside the electric switch body 1, and the wireless signal module 12 outside the electric switch body 1 lacks protection, so that the wireless signal module 12 is easily damaged by collision. The protective mechanism can protect the wireless signal module 12 on the electric switch body 1 through the protective cover 34 to avoid collision damage to the wireless signal module 12, thereby extending the service life of the electric switch for the fracturing device.

[0025] Furthermore, the protective frame 2 is in a "U" shape, the thickness of the protective frame 2 is greater than the thickness of the push-type switch button 11, and a guide groove is provided on the surface of the protective frame 2. The protective plate 21 slides on the guide groove of the protective frame 2. During the sliding process of the protective plate 21 on the guide groove of the protective frame 2, the protective plate 21 will not contact the push-type switch button 11, thereby ensuring that the push-type switch button 11 will not be accidentally touched by the sliding of the protective plate 21.

[0026] Furthermore, the bottom plate 22 slides on the surface of the electric switch body 1 through the protective plate 21, and the limit plate 25 limits the sliding range of the protective plate 21 and the bottom plate 22 on the surface of the electric switch body 1. When the bottom plate 22 slides on the electric switch body 1 until it contacts and is connected to the limit plate 25, the protective plate 21 and the bottom plate 22 cannot slide downward on the electric switch body 1, thereby preventing the protective plate 21 from sliding out of the guide groove of the protective frame 2. At the same time, when the protective plate 21 slides onto the protective frame 2, the protective frame 2 and the protective plate 21 cooperate with the bottom plate 22 to protect the push-type switch button 11.

[0027] Furthermore, the protective plate 21 and the base plate 22 are perpendicular to each other, and the base plate 22 and the fixed plate 23 are parallel to each other. The elastic force of the spring 24 acts on the protective plate 21 through the base plate 22, so that the position of the protective plate 21 on the guide groove of the protective frame 2 is relative. In the absence of external force, the protective plate 21 is always directly in front of the push-type switch button 11.

[0028] Furthermore, the knob 32 drives the bidirectional screw rod 31 to rotate on the surface of the fixed block 3, and the bidirectional screw rod 31 drives the square nut 33 to slide on the surface of the electric switch body 1 by rotation. There are two groups of square nuts 33, and the sliding directions of the two groups of square nuts 33 are opposite. After the square nut 33 is moved, the bidirectional screw rod 31 will limit the position of the square nut 33 on the electric switch body 1.

[0029] Furthermore, the protective cover 34 slides on the surface of the electric switch body 1 through the square nut 33. Two groups of protective covers 34 are provided, and the two groups of protective covers 34 can slide on the top of the electric switch body 1 until they are in contact and connected with each other. At this time, the two groups of protective covers 34 completely block the wireless signal module 12 on the surface of the electric switch body 1, protecting the wireless signal module 12 when the wireless signal module 12 is not in use.

[0030] Working principle: Before operating the push-type switch button 11, pull the bottom plate 22 to make the protective plate 21 slide on the guide groove of the protective frame 2, so that the bottom plate 22 contacts and is connected to the surface of the limit plate 25. At this time, the push-type switch button 11 can be operated, and the elastic force of the spring 24 acts on the protective plate 21 through the bottom plate 22, so that the protective plate 21 slides on the guide groove of the protective frame 2 to the front of the push-type switch button 11, blocking the push-type switch button 11, making it impossible for the operator to operate, avoiding the operator from accidentally touching the push-type switch button 11, preventing the fracturing device from accidentally exploding, and improving the safety of the fracturing device during use.

[0031] When the wireless signal module 12 is not in use, the bidirectional screw rod 31 is driven to rotate on the fixed block 3 by rotating the knob 32. The bidirectional screw rod 31 drives the two sets of square nuts 33 to approach each other on the electric switch body 1 through rotation. The square nuts 33 drive the two sets of protective covers 34 to slide toward the wireless signal module 12, so that the two sets of protective covers 34 are in contact and connected together. At this time, the two sets of protective covers 34 protect the wireless signal module 12 on the electric switch body 1 to prevent the wireless signal module 12 from being damaged by collision, thereby extending the service life of the electric switch for the fracturing device.

[0032] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
