[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] The utility model provides Figure 1-Figure 4 The fire truck water flow meter shown includes:

[0026] The device body 1 and the connecting plate 2, the rear side of the device body 1 is fixedly connected with a fixing seat 3, and the left and right sides of the device body 1 are provided with adapters, so that it can be connected to the fire truck without using the same adapter as the fire hose, and the other end can be used to connect the fire hose, and the water flow through the middle can be sensed to display the pressure and flow of the water flow, and the connecting plate 2 can be welded to the corresponding position outside the fire truck;

[0027] The limiting mechanism includes a bidirectional screw rod 4 rotatably connected to the fixing seat 3. The fixing seat 3 is provided, and the fixing seat 3 can support the bidirectional screw rod 4 to avoid the bidirectional screw rod 4 from deflecting and shaking during use, thereby ensuring the stable use of the bidirectional screw rod 4;

[0028] The bidirectional screw rod 4 is externally threadedly connected to two limit blocks 5, the front sides of the two limit blocks 5 are fixedly connected to moving blocks 6, the two moving blocks 6 are hinged with rotating rods 7 through four pins, the close ends of the two rotating rods 7 are hinged with the same connecting block 8 through two pins, the two connecting blocks 8 are fixedly connected to support rods 9, and the front ends of the support rods 9 are fixedly connected to a protective shell 10.

[0029] The bidirectional screw rod 4 is externally rotatably connected to a support seat 11, and two moving grooves 12 are provided on the front side of the support seat 11. By providing the moving grooves 12, and the cooperation between the moving grooves 12 and the support rod 9, the support rod 9 can be prevented from being offset and misaligned when moving, thereby ensuring the stable use of the support rod 9;

[0030] The rear end of the support rod 9 is slidably connected in the corresponding movable groove 12, the rear side of the support seat 11 is fixedly connected with a square block 13, and the front side of the connecting plate 2 is provided with a square groove 14. By setting the square groove 14, the square groove 14 and the square block 13 cooperate with each other, so as to avoid the support seat 11 from deviating and shaking when in use, thereby ensuring the stable use of the support seat 11;

[0031] The rear end of the square block 13 is slidably connected in the square groove 14. The top and bottom of the connecting plate 2 are provided with a card slot 15. By providing the card slot 15, and the card slot 15 and the limit card block 5 cooperate with each other, the device can be quickly installed and fixed;

[0032] The limit block 5 is slidably connected in the corresponding slot 15, a handle 16 is fixedly connected to the bottom of the bidirectional screw rod 4, and a stop block 17 is provided at the top of the bidirectional screw rod 4. By setting the stop block 17, the stop block 17 can block the limit block 5 to prevent it from being separated from the bidirectional screw rod 4 when moving, thereby ensuring the stable use of the limit block 5. A meter 18 is provided on the top of the device body 1, and the protective shell 10 abuts against the outside of the meter 18.

[0033] The working principle of the utility model is:

[0034] When using the device, first align the square block 13 with the square groove 14 and insert it, then you can rotate the handle 16. While the handle 16 drives the bidirectional screw rod 4 to rotate, the two limit blocks 5 move toward each other outside the bidirectional screw rod 4, so that they can be inserted into the corresponding grooves 15. When the two limit blocks 5 drive the two moving blocks 6 to move synchronously, the corresponding two rotating rods 7 are driven to rotate relative to each other under the action of the pin shaft, so that the corresponding two connecting blocks 8 drive the support rod 9 to move relative to each other in the moving groove 12, and the support rod 9 drives the corresponding protective shell 10 to open relatively.

[0035] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
