[0023] The utility model discloses below make detailed instructions, clear, complete to the technical scheme of the embodiment of the utility model, obviously, the described embodiment is only a part of the embodiment of the utility model, instead of all the embodiment. Based on the embodiment in the utility model, all other embodiments that the ordinary skill in the art obtains without making creative labor belong to the range of protection of the utility model.

[0024] The utility model discloses a kind of gas ultrasonic flowmeter convenient for overhaul, the technical scheme of the utility model is:

[0025] As Figures 1-4 As shown in a kind of gas ultrasonic flowmeter convenient for overhaul, including base 1, two mountings 2 are fixed symmetrically on the outside of base 1, and the upper side of base 1 is provided with connecting seat 3, and control assembly 4 is installed on the upper side of connecting seat 3, further comprising: mounting mechanism, mounting mechanism is arranged in the inside of connecting seat 3;Mounting mechanism includes rotating sleeve 5 that is rotatably connected to the inside of connecting seat 3, sliding rod 6 that is slidably connected to the inside of connecting seat 3, the inside of rotating sleeve 5 is rotatably connected with two screw rods 7 by screw thread symmetrically, two screw rods 7 are rotatably connected to the inside of connecting seat 3, gear 8 is fixed on the outside of rotating sleeve 5 at middle segment position, one end of sliding rod 6 is fixed with rack 9 engaged with gear 8, and the outside of sliding rod 6 is fixed with fixed block 10, and sliding rod 6 is provided with spring 11 on the outside, one end of spring 11 is fixed with one end of rack 9, and the other end of spring 11 is fixed with fixed block 10;

[0026] Combining the description of the above mounting assembly, when needing to overhaul the separation between base 1 and control assembly 4, pull sliding rod 6, make it slide along the inside of connecting seat 3, simultaneously extrude spring 11, utilize the elastic potential energy of spring 11, it is convenient for subsequent reset, to ensure the feasibility of repositioning, sliding rod 6 moves and drives rack 9 to move synchronously, rack 9 moves and drives gear 8 to rotate through gear engagement, gear 8 is fixed on the outside of rotating sleeve 5, and then rotating sleeve 5 rotates, rotating sleeve 5 rotates and drives two screw rods 7 to rotate and move relative through screw thread engagement, when two screw rods 7 are separated from the mounting hole in the inside of two mountings 2 respectively, the limitation is released, at this moment, mounting 2 can be pulled out upward, and overhaul is carried out separately, improve the operational space, and then improve the overhaul efficiency, and similarly, when needing to install, connecting seat 3 is placed on the upper side of base 1, and then operation is carried out again, when sliding rod 6 resets, two screw rods 7 reset, and positioning is carried out.

[0027] As Figure 4 As shown in an embodiment, in order to facilitate the operator to hold and pull, the outer end of sliding rod 6 is fixed with pull handle 12, and pull handle 12 is specifically polygonal.

[0028] As Figure 1As shown, in one embodiment, an air pipe 13 is provided on the inner side of the base 1, and a connecting flange 14 is provided at both ends of the air pipe 13.

[0029] like Figure 2 As shown, in one embodiment, a display component 15 is installed on one side of the control component 4, through which data can be displayed.
