[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Example 1, as Figures 1 to 4 As shown, this utility model provides a wireless pressure verification device, including a wireless pressure verification device body 1, which is the core part of the entire device. It integrates data processing and other functions. A wireless communication module 2 is fixedly connected to the left side of the front of the wireless pressure verification device body 1. The wireless communication module 2 adopts advanced wireless communication technology, such as LoRa, NB-IoT or 4G, to send data to a monitoring center or cloud server for convenient real-time viewing by users. A line 5 is fixedly connected to the rear left side of the wireless pressure verification device body 1. A pressure sensor 6, model DM4001, is fixedly connected to the left end of the line 5. The pressure sensor 6 is used to sense external pressure signals and transmit the signals to the wireless pressure verification device body 1 for processing. A storage component 7 is provided on the left side of the wireless pressure verification device body 1, which can conveniently store excess lines 5.

[0026] Example 2, as Figures 1 to 4 As shown, a base 3 is fixedly connected to the bottom of the wireless pressure verification device body 1. A mounting plate 4 is attached to the bottom of the base 3. The mounting plate 4 is used to fix the wireless pressure verification device to a specific position or device with screws. The base 3 serves to support and fix the device. A through-hole 31 is provided on the front and back of the right side of the base 3. The design of the through-hole 31 provides a basis for positioning and connection of the mounting plate 4. A blocking block 32 is movably connected to the lower right side of the base 3. The blocking block 32 is semi-circular and can cooperate with the blocking groove 44 after the mounting plate 4 is installed in place, preventing the wireless pressure verification device body 1 from moving left or right. A fixing block 41 is fixedly connected to the middle left side of the upper surface of the mounting plate 4. The fixing block 41 provides a basis for the installation of other components. The right side of the fixing block 41... Positioning rods 42 are fixedly connected to both the front and rear sides. The length of the positioning rods 42 is greater than the length of the base 3 and the socket 31. Rubber sleeves 43 are fixedly connected to the right side of the outer surface of the front and rear positioning rods 42. The outer surface diameter of the front and rear rubber sleeves 43 is greater than the inner wall diameter of the socket 31. During installation, the rubber sleeves 43 will first contact the inner wall of the socket 31 and generate a certain friction force, which plays a preliminary positioning role. At the same time, tapered surfaces are provided on the left and right sides of the outer surface of the front and rear rubber sleeves 43, which facilitates the squeezing and contraction of the rubber sleeves 43 when the positioning rods 42 are inserted into the socket 31. The outer surface diameter of the front and rear positioning rods 42 is smaller than the inner wall diameter of the socket 31. The outer surface of the front and rear positioning rods 42 is slidably connected to the inside of the socket 31. This design allows the positioning rods 42 to be smoothly inserted into the socket 31, realizing quick installation and removal operations.

[0027] A blocking groove 44 is provided in the middle of the right side of the upper surface of the mounting plate 4. The inner wall of the blocking groove 44 corresponds to the right side of the base 3. When the mounting plate 4 is installed in place, the outer surface of the blocking block 32 overlaps with the inside of the blocking groove 44, which further enhances the connection stability between the mounting plate 4 and the base 3.

[0028] Example 3, as Figures 1 to 4 As shown, the storage component 7 includes a first plate 71. The lower surface of the first plate 71 is fixedly connected to the upper surface of the fixing block 41. Several storage slots 72 are provided on both the front and rear sides of the first plate 71. Rubber blocking blocks 74 are fixedly connected to the upper and lower surfaces of the inner walls of the several storage slots 72. The rubber blocking blocks 74 can prevent the wires 5 stored in the storage slots 72 from falling out. An arc-shaped groove 73 is provided on the side of the inner wall of the several storage slots 72 away from the rubber blocking blocks 74. The arc-shaped groove 73 is designed to facilitate the adhesion of the outer surface of the wires 5 after winding. Plate 2 75 is fixedly connected to the upper surface of plate 1. A placement groove 76 is provided in the middle of the upper surface of plate 2 75. The placement groove 76 can be used to limit the placement of pressure sensor 6 before installation. A horizontal plate 77 is fixedly connected to the middle of the upper surface of plate 2 75. A fixing bolt 78 is threaded through the outer surface of the horizontal plate 77. A pressing block is fixedly connected to the lower end of the fixing bolt 78. The pressing block is made of rubber. By rotating the fixing bolt 78, the pressing block can be pressed down, which limits and locks the pressure sensor 6 placed in the placement groove 76, preventing it from shaking during transportation.

[0029] Working principle: First, the blocking block 32 is rotated and separated from the inside of the blocking groove 44. Then, the wireless pressure verification instrument body 1 is moved directly to drive the base 3, causing the socket 31 to slide outward on the outer surface of the positioning rod 42. At the same time, the socket 31 is designed to facilitate contact with the conical surface in the rubber sleeve 43. As the wireless pressure verification instrument body 1 continues to move, the surface of the rubber sleeve 43 is squeezed and contracted, thus completing the disassembly operation. Conversely, during installation, the wireless pressure verification instrument body 1 is moved to cause the socket 31 to squeeze and contract the rubber sleeve 43 again, thus causing the socket 31 to slide inward on the surface of the positioning rod 42 to achieve installation. At the same time, the repositioned rubber sleeve 43 facilitates the blocking of the inner wall of the socket 31. By rotating the blocking block 32 into the inside of the blocking groove 44, the locking function of the wireless pressure verification instrument body 1 after installation is strengthened.

[0030] When it is necessary to store the wire 5, the fixing bolt 78 is rotated to loosen it from the pressure sensor 6, the pressure sensor 6 is taken out from the placement slot 76, and the excess wire 5 is wound around the plate 71, so that the wire 5 is squeezed and contracted between the two rubber blocking blocks 74, thereby entering the storage slot 72 and the arc-shaped groove 73 for contact and winding. After the wire 5 enters, the upper and lower rubber blocking blocks 74 reset to close the interior of the storage slot 72, preventing the wire 5 from falling out of position. After the excess wire 5 is wound and stored, the removed pressure sensor 6 is installed, thereby completing the storage effect of the excess wire 5.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
