Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figures 1-3This utility model provides a gas bellows pressure detection device, including a base plate 1, a pull plate 2 inserted into one side of the inner wall of the base plate 1, a gas supply box 4 fixedly mounted on the surface of the base plate 1, the inner wall of the gas supply box 4 being hollow, a one-way valve 5 fixedly connected to the lower end of one side wall of the gas supply box 4, the flow direction of the one-way valve 5 being from the outside to the inside, three gas outlet pipes 6 fixedly connected to the other side wall of the gas supply box 4, each gas outlet pipe 6 having a tapered pipe 7 screwed to its outer wall, a vertical plate 10 fixedly connected to the side end of the pull plate 2, three tapered plugs 9 fixedly mounted on the side wall of the vertical plate 10 near the gas supply box 4, each tapered plug 9 corresponding to a tapered pipe 7.

[0015] By using the base plate 1 and the draw plate 2 together, the distance between the two tapered tubes 7 and the tapered plugs 9 can be adjusted to accommodate gas bellows of different lengths and specifications. Through the function of the gas supply box 4 and the cooperation of the one-way valve 5, the experimental gas can be supplied to the gas supply box 4 via an external pressure supply line connected to the one-way valve 5. Simultaneously, the gas supply box 4 distributes the gas to each outlet pipe 6. Through the screw connection between the outlet pipe 6 and the tapered tube 7, different tapered tubes 7 can be replaced, facilitating maintenance. Meanwhile, the outer wall of the tapered tube 7... It can be used with gas bellows of different diameters. The gas bellows is manually pressed against the outer wall of the conical tube 7 and tightly attached to the conical tube 7. It also cooperates with the conical plug 9 on the side wall of the vertical plate 10. The conical plug 9 can also be used with gas bellows of different diameters. The other end of the bellows needs to be manually pressed against the outer wall of the conical plug 9 and tightly attached to the conical plug 9. Multiple sets can be set up to ensure that multiple sets of experiments can be carried out at the same time, ensuring the experimental effect and the efficiency of the pressure test. It is convenient to use and highly practical.

[0016] It also includes multiple clamping structures 8. Two clamping structures 8 are assembled on both sides of the tapered tube 7 and the tapered plug 9, and the two clamping structures 8 are arranged symmetrically.

[0017] The clamping structure 8 includes an electric telescopic rod 81, which is fixedly mounted on the side wall of the air supply box 4 or the vertical plate 10. The piston rod end of the electric telescopic rod 81 is fixedly mounted with a support plate 82. A screw rod 84 is screwed to the inner wall of the support plate 82. A handle 83 is fixedly mounted on the side of the screw rod 84 away from the tapered tube 7 or the tapered plug 9. A semi-circular ferrule 85 is rotatably mounted on the side of the screw rod 84 close to the tapered tube 7 or the tapered plug 9.

[0018] When the clamping structure 8 is required, the end of the bellows is pre-fitted onto the outer wall of the tapered pipe 7 or tapered plug 9. Then, the handles 83 on both sides are rotated, and the adjusting screw 84 rotates on the inner wall of the support plate 82. After the semi-circular sleeve 85 is fitted onto the outer wall of the bellows, the handles 83 and adjusting screw 84 are rotated closer to the bellows. At this time, the semi-circular sleeve 85 does not rotate with the screw 84, but instead drives the semi-circular sleeve 85 to fit more tightly onto the outer wall of the bellows until it is completely locked. Then, the electric telescopic rod 81 is activated, and the piston rod is retracted. The semi-circular sleeve 85 drives the bellows to fit tightly onto the outer wall of the tapered pipe 7 or tapered plug 9, saving labor.

[0019] A screw 3 is threaded through the side wall of the base plate 1, and the screw 3 is threaded into the drawer plate 2.

[0020] Screw 3 ensures the stability of the pull plate 2 after adjustment.
