For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] The technical solution of the utility model is further described in detail below in conjunction with the accompanying drawings and specific embodiments of the specification;

[0025] Embodiment 1: The present application provides a hard pipe sealing pressure testing device, comprising a testing box 1; a placement plate 3 is movably installed inside the testing box 1, a sealing mechanism 6 is installed on the top of the placement plate 3, and a pressure detection mechanism 4 is installed at one end of the sealing mechanism 6;

[0026] The sealing mechanism 6 includes a sealing plate 1 601, a sealing plate 2 602, a groove 603 and a sealing ring 604. The sealing plate 1 601 is installed at one end of the top of the placement plate 3, and the sealing plate 2 602 is installed at one end of the top of the placement plate 3 away from the sealing plate 1 601. The insides of the sealing plate 1 601 and the sealing plate 2 602 are both provided with a groove 603, and the inner wall of the groove 603 is provided with a sealing ring 604;

[0027] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the placement plate 3 is used to place the hard tube for testing, and the sealing mechanism 6 is used to keep the two ends of the hard tube sealed, by clamping one end of the hard tube in the groove 603 inside the sealing plate 1 601, and then clamping the other end of the hard tube in the groove 603 inside the sealing plate 2 602, the sealing ring 604 in the groove 603 can keep the two ends of the hard tube sealed, at this time, when the pressure detection mechanism 4 works to inflate the inside to detect the pressure, gas leakage can be avoided, and the pressure detection mechanism 4 is used to detect the sealing of the hard tube.

[0028] Further, the pressure detection mechanism 4 includes a through pipe 401, a valve 402 and a through port 403. The through pipe 401 is installed at one end of the sealing plate 1 601 away from the sealing plate 2 602, the valve 402 is installed on the outside of the through pipe 401, and the through port 403 is provided at the central position inside the sealing plate 1 601;

[0029] Specifically, Figure 3 and Figure 4 As shown, in order to realize the pressure sealing test of the hard tube, the external gas is transported to the inside of the hard tube between the sealing plate 1 601 and the sealing plate 2 602 through the through pipe 401 through the port 403, and then the pressurized hard tube is transported to the inside of the detection box 1 to see whether the liquid bubbles. Bubbling indicates that the sealing of the hard tube is unqualified. When the valve 402 is closed, the external gas can be stopped from being transported to the inside of the hard tube.

[0030] Further, a support plate 8 is movably installed at the central position of the top of the placement plate 3;

[0031] Specifically, Figure 1 and Figure 2 As shown, in order to facilitate the movement and placement of the hard pipe, the support plate 8 is movably arranged on the top of the placement plate 3, and the support plate 8 can facilitate the device to place and move the hard pipe.

[0032] Further, a driving device 7 is installed at one end of the sealing plate 601, and a nozzle 701 is installed at one end of the driving device 7;

[0033] Specifically, Figure 4 As shown, in order to remove impurities from the inside of the hard tube and prevent the impurities from affecting the results of the hard tube sealing test, the driving device 7 is an existing circular electromagnetic slide rail structure, one side of which is connected to a nozzle 701, and the nozzle 701 is connected to the inside of the opening 403. When the pressure detection mechanism 4 ventilates the inside of the hard tube, the gas can be synchronously sprayed out through the nozzle 701, and then the impurities inside the hard tube can be removed. As the driving device 7 drives the nozzle 701 to move, the gas spraying position can be changed.

[0034] Further, a threaded rod 301 is installed at one end of the top of the placement plate 3, and a sealing plate 2 602 is connected to the movable end of the threaded rod 301;

[0035] Specifically, Figure 1 As shown, in order to fix the hard tube and seal both ends, one end of the hard tube is located inside the sealing plate 1 601, and then the threaded rod 301 is rotated so that the moving end of the threaded rod 301 drives the sealing plate 2 602 to move, so that the sealing plate 2 602 is located at the other end of the hard tube, thereby sealing and fixing both ends of the hard tube.

[0036] Furthermore, transmission rods 2 are installed inside the two ends of the detection box 1, and the outer side of the transmission rod 2 is transmission-connected with a placement plate 3;

[0037] Specifically, Figure 1 , Figure 2 and Figure 3 As shown, in order to adjust the pressure-filled hard tube and transport it to the inside of the detection box 1 for detection, the transmission rod 2 is composed of an existing motor and a threaded rod, which can prompt the placement plate 3 to move up and down, so that the hard tube on the top of the placement plate 3 can be located inside the detection box 1 for detection or moved out of the detection box 1, thereby facilitating the worker's operation.

[0038] Furthermore, a pressure gauge 5 is installed at one end of the sealing plate 2 602 away from the sealing plate 1 601;

[0039] Specifically, Figure 1 As shown, in order to achieve the auxiliary sealing detection function for the hard tube, when the pressure detection mechanism 4 inflates the inside of the hard tube, the pressure in the hard tube can be detected synchronously by the pressure gauge 5.

[0040] Working principle: by placing the hard tube to be tested on the top of the support plate 8, and then ventilating the inside of the hard tube through the pressure detection mechanism 4, the gas can be simultaneously sprayed out through the nozzle 701, and then the inside of the hard tube can be removed. At this time, by rotating the threaded rod 301, the moving end of the threaded rod 301 drives the sealing plate 2 602 to move, so that the sealing plate 2 602 is located at the other end of the hard tube. At this time, the external gas is transported to the inside of the hard tube between the sealing plates 1 601 and 602 through the through pipe 401 through the through port 403. As the transmission rod 2 drives the placement plate 3 to move toward the inside of the detection box 1, the pressure-filled hard tube is transported to the inside of the detection box 1 to see whether the liquid is bubbling. Bubbling indicates that the sealing of the hard tube is unqualified.

[0041] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified and replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
