Description

Technical Field

[0001] This utility model relates to the field of instrument technology in the explosives industry, specifically to a pressure gauge testing device for explosives production lines. Background Technology

[0002] Due to the demand for weapons and equipment, production lines have increased, leading to a greater demand for pressure measuring instruments.

[0003] Currently, during the disassembly and transfer of pressure gauges for inspection, woven bags or wooden crates are typically used. The pressure gauges are placed directly inside these bags or crates, and then transported by two or more operators. This method presents several safety hazards. First, it causes severe vibrations during transport, damaging the pressure gauge's resin faceplate and body. Second, static electricity can easily accumulate during transport. Finally, various acids, alkalis, and toxic media remaining in the pressure gauge's measuring tube can easily leak out. Utility Model Content

[0004] To overcome the technical defects of existing dedicated pressure gauges that are easily damaged, accumulate static electricity, or leak toxic media during the transfer process, this utility model provides a dedicated pressure gauge testing device for explosives production lines.

[0005] This utility model provides a pressure gauge inspection device specifically for explosives production lines, comprising: a housing and a cover that are mutually compatible, a gauge housing fixing layer, a connector fixing layer, and a static-dissipating wristband; a U-shaped handle is connected to the cover, and the static-dissipating wristband is connected to the U-shaped handle; the gauge housing fixing layer is fixedly connected to the housing and parallel to the bottom of the housing, and the gauge housing fixing layer is provided with a plurality of rectangular mounting holes arranged in an array, the rectangular mounting holes being compatible with the pressure gauge housing; the connector fixing layer is connected to the housing below the gauge housing fixing layer, and the connector fixing layer is provided with a plurality of cylindrical receiving slots arranged in an array, the number of cylindrical receiving slots being equal to the number of rectangular mounting holes and their positions corresponding vertically, the cylindrical receiving slots being used to fix the pressure gauge connector and collect toxic media.

[0006] The pressure gauge is placed on the casing and connector fixing layers of the housing. The casing is fitted into a rectangular mounting hole, and the pressure gauge connector is inserted into a cylindrical receiving groove. This ensures the pressure gauge is fixed in position inside the housing, effectively protecting it from compression damage. During transportation, in the event of a toxic leak, the cylindrical receiving groove can collect the leaked liquid, preventing harm to workers from acids or alkalis and reducing safety risks. In use, the conductive wristband is worn on the worker's wrist. Static electricity accumulates, reaches the body, and is then discharged, improving the device's functionality and practicality. The conductive wristband must be made of copper or other conductive materials. It is self-explanatory that the size of the conductive wristband should be suitable for the user's wearing needs.

[0007] Preferably, a window is provided on the front side wall of the housing below the watch case fixing layer, and guide rails are respectively provided on the left and right inner side walls of the housing below the watch case fixing layer. The connector fixing layer passes through the window and its left and right sides slide in cooperation with the guide rails. A push switch for controlling the entry and exit of the connector fixing layer is provided between the front side of the connector fixing layer and the front side of the housing. This arrangement ensures that the connector fixing layer can be easily removed and facilitates the cleaning of the cylindrical receiving groove in the connector fixing layer.

[0008] Preferably, the watch case fixing layer is fixedly connected to the housing by multiple screws. This connection ensures structural stability and facilitates replacement. In other embodiments, the watch case fixing layer may also be integrally formed with the housing, or directly welded to the housing.

[0009] Preferably, the rear side of the box body and the rear side of the lid are hinged together, and the front side of the box body and the front side of the lid are connected by a snap fastener. This design makes operation more convenient and ensures a secure lock.

[0010] Preferably, the housing and U-shaped handle are made of Hastelloy C276 alloy, while the cover, casing fixing layer, and connector fixing layer are made of high-density polyethylene / graphite conductive composite material. High-density polyethylene / graphite conductive composite material is a mature material in this field; it is a conductive composite material prepared by physical blending using high-density polyethylene as the matrix material and graphite as the conductive filler. It possesses both good mechanical properties and good electrical conductivity, meeting the requirements of this device. Hastelloy C276 is a nickel-based alloy material, resistant to high temperatures and corrosion, and also possesses both good mechanical properties and good electrical conductivity, meeting the requirements of this device. The U-shaped handle can also be made of copper or other materials that meet the requirements for electrostatic conductivity and structural performance.

[0011] Preferably, the cover, the casing fixing layer, and the connector fixing layer are connected by jumper wires. The jumper wires enable the conduction of static electricity accumulated throughout the device, resulting in a more uniform distribution of static electricity and preventing accidents caused by excessive static electricity accumulation in certain areas.

[0012] Preferably, the jumper wire is made of copper or aluminum wire. Copper or aluminum wire has good conductivity, but other conductive wires can also be used for the jumper wire.

[0013] Preferably, a sponge pad is provided inside the cover to prevent the pressure gauge from shaking inside the housing.

[0014] Preferably, multiple digital rollers are rotatably connected to the outer side of the cover, and the outer surface of the digital rollers is engraved with numbers from zero to ninety. Specifically, five digital rollers can be set, with the first three numbers representing the production line code and the last two numbers representing the quantity to be inspected, thereby reducing the error rate and improving work efficiency.

[0015] Compared with the prior art, the technical solution provided by this utility model has the following technical effects: The pressure gauge inspection device for explosives production lines provided by this utility model is equipped with a box, a cover, a connector fixing layer, a watch case fixing layer, a cylindrical receiver, a U-shaped handle, and a static discharge wristband. In use, the pressure gauge is inserted face down into the watch case holder, the connector of the pressure gauge is inserted into the corresponding cylindrical receiving slot, the cover is closed, and the operator wears the static discharge wristband and holds the U-shaped handle for inspection. This device can, on the one hand, fix the pressure gauge inside the box, reducing wear on the glass dial and collisions between precision instruments during inspection; on the other hand, various acids, alkalis, and toxic media remaining in the pressure gauge's measuring tube are collected in the cylindrical receiving slot inside the box, reducing safety risks, and also allowing the accumulated static electricity to be discharged through the human body; secondly, the digital roller above the cover can record the production line code and the quantity of inspections, reducing the error rate and improving inspection efficiency.
