Technical Field

[0001] The utility model belongs to the technical field of instruments and meters, in particular to an instrument for a corrosion-resistant pressure tank. Background Art

[0002] Instruments and meters are devices or equipment used to detect, measure, observe and calculate various physical quantities, material components, physical parameters, etc. Vacuum leak detectors, pressure gauges, length gauges, microscopes, multipliers, etc. are all instruments and meters. In a broad sense, instruments and meters can also have functions such as automatic control, alarm, signal transmission and data processing.

[0003] In the daily use of pressure tanks, pressure gauges are needed to detect the internal pressure in real time to prevent the internal pressure from being too low and affecting normal use. However, pressure gauges are generally connected to the outside of the pressure tank, which makes the pressure gauges vulnerable to collisions with foreign objects, causing damage to the pressure gauges and affecting their service life. Utility Model Content

[0004] In order to overcome the above defects, the utility model provides a corrosion-resistant pressure tank instrument, which solves the problem that the pressure instrument connected to the outside of the pressure tank is easily hit by foreign objects, causing damage to the pressure instrument and affecting its service life.

[0005] To achieve the above object, the utility model provides the following technical solutions: a corrosion-resistant pressure tank instrument, comprising a pressure tank body, a mounting seat connected to the pressure tank body, a connecting sleeve connected to the mounting seat, a pressure gauge connected to the mounting seat through the connecting sleeve, a protective shell installed on the mounting seat, a mounting groove opened on the mounting seat, sliding grooves opened on the inner walls on both sides of the mounting groove, a threaded sleeve installed on the mounting seat, and a threaded rod threadedly connected to the threaded sleeve;

[0006] One end of the threaded rod is connected to a rotating wheel, and the other end of the threaded rod is rotatably connected to a clamping plate, and the clamping plate is connected to a plug rod. An observation window is installed on the protective shell, and hollow plates are connected to both sides and the top of the protective shell, and a buffer spring is connected inside the hollow plate. One end of the buffer spring is connected to a movable plate, a fixed plate is connected below the pressure gauge, and a connecting pipe is connected below the fixed plate.

[0007] As a further solution of the utility model: sliding blocks are connected to both sides of the clamping plate, and the sliding blocks are T-shaped and slide in the sliding grooves.

[0008] As a further solution of the utility model: a buffer pad is connected to the movable plate, a plug plate is connected below the protective shell, a plug plate is provided with a plug hole, and the plug rod is plugged into the plug hole.

[0009] As a further solution of the utility model: an elastic clamping block is connected below the fixing plate, and there are four elastic clamping blocks in total, which are symmetrical about the axis of the connecting pipe, and the bottom of the elastic clamping block is designed in a triangle.

[0010] As a further solution of the utility model: threaded holes are provided on the connecting sleeve and the fixing plate, a clamping groove is provided on the inner wall of the connecting sleeve, and the clamping groove and the elastic clamping block are interlocked.

[0011] As a further solution of the utility model: a sealing gasket is arranged on the outer wall of the connecting pipe, and a plurality of sealing rings are connected to the sealing gasket.

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

[0013] 1. The corrosion-resistant pressure tank instrument is provided with a mounting groove, a threaded rod, a rotating wheel, a clamping plate, a plugging rod, a protective shell, a hollow plate, a buffer spring, a movable plate, a plugging plate and a socket. The plugging plate is inserted into the mounting groove, and the rotating wheel is turned to rotate the threaded rod at the same time, so that the threaded rod can push the clamping plate to move, so that the clamping plate presses and fixes the plugging plate, and at the same time the plugging rod is inserted into the socket, so that the protective shell is fixed on the mounting seat, covering the pressure gauge, reducing the contact between the pressure gauge and the outside world, and preventing the pressure gauge from being corroded by the outside world. When collided with by foreign objects, the collision object will hit and push the movable plate, so that the movable plate enters into the hollow plate to compress the buffer spring, and the impact force generated by the collision is buffered, thereby protecting the pressure gauge and preventing the pressure gauge from being damaged.

[0014] 2. The corrosion-resistant pressure tank instrument is provided with a connecting sleeve, a fixing plate, a connecting pipe, a threaded hole, an elastic card block and a card slot. The connecting pipe is inserted into the connecting sleeve so that the threaded holes on the connecting sleeve and the fixing plate are aligned with each other, and the bolt assembly is screwed into the threaded hole to fix the pressure gauge on the connecting sleeve. When the connecting pipe is inserted into the connecting sleeve, the inner wall of the connecting sleeve pushes and squeezes the elastic card block through the triangular inclined surface of the elastic card block, causing the elastic card block to produce elastic deformation, so that the elastic card block is stuck in the card slot, thereby fixing the pressure gauge to prevent the pressure gauge from accidentally rotating when the staff screws the bolt assembly.

[0022] An insertion rod 12 is connected to the splint 11, an observation window 14 is installed on the protective shell 5, hollow plates 15 are connected to both sides and the top of the protective shell 5, a buffer spring 16 is connected inside the hollow plate 15, one end of the buffer spring 16 is connected to a movable plate 17, a buffer pad 18 is connected to the movable plate 17, an insertion plate 19 is connected to the bottom of the protective shell 5, a socket 20 is provided on the insertion plate 19, the insertion rod 12 is inserted into the socket 20, and the impact force generated by the collision of the collision object is buffered by the buffer pad 18 to prevent the collision object from damaging the movable plate 17, and the connection between the insertion rod 12 and the socket 20 can prevent the protective shell 5 from shaking.

[0023] A fixing plate 21 is connected below the pressure gauge 4, and an elastic card block 24 is connected below the fixing plate 21. There are four elastic card blocks 24 that are symmetrical about the axis of the connecting pipe 22. The elastic card blocks 24 are designed in a triangle below. The triangular elastic card blocks 24 can be easily pushed and squeezed by the inner wall of the connecting sleeve 3, thereby facilitating the staff to disassemble and assemble the pressure gauge 4.

[0024] A threaded hole 23 is provided on the connecting sleeve 3 and the fixing plate 21, and a slot 25 is provided on the inner wall of the connecting sleeve 3. The slot 25 and the elastic block 24 are engaged with each other. By screwing a bolt into the threaded hole 23, the fixing effect of the pressure gauge 4 can be further improved, and the angle of the pressure gauge 4 can be fixed by the engagement of the elastic block 24 and the slot 25, preventing the pressure gauge 4 from rotating when the staff screws the bolt into the threaded hole 23.

Then, the plug plate 19 is inserted Insert it into the installation groove 6, and turn the rotating wheel 10 to rotate the threaded rod 9, so that the threaded rod 9 pushes the clamping plate 11 to move, causing the clamping plate 11 to press and fix the plug plate 19, and at the same time the plug rod 12 will be inserted into the socket 20, so that the protective shell 5 is fixed on the mounting seat 2 to prevent the protective shell 5 from shaking, so that the protective shell 5 can cover the pressure gauge 4 and reduce the contact between the pressure gauge 4 and the outside world. When the pressure gauge 4 is collided, the collision object will impact and push the moving plate 17, so that the moving plate 17 enters the hollow plate 15 to compress the buffer spring 16 to buffer the impact force, thereby protecting the pressure gauge 4.
