[0024] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following will make a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings of the specification.

[0025] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0026] Secondly, the "one embodiment" or "embodiment" mentioned herein refers to specific features, structures, or characteristics that may be included in at least one implementation manner of the present invention. The phrase "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments.

[0027] As shown in the appended Figure 1 to the appended Figure 5 figures:

[0028] Embodiment 1: This embodiment provides a mobile water gun universal labor-saving pressurizing operation frame, which includes a main body 1, a longitudinal adjustment mechanism 2, a transverse adjustment mechanism 3, and a connecting piece 4; the main body 1 includes a fixed frame 101, a water spray pipe 108 is movably arranged inside the fixed frame 101, universal wheels 102 are arranged at the bottom of the fixed frame 101, and a pedal 103 is movably arranged on one side of the fixed frame 101; the transverse adjustment mechanism 3 includes a bearing 303 movably arranged between the water spray pipe 108 and the fixed frame 101, a first gear 302 is arranged on the water spray pipe 108, a second gear 306 is movably arranged inside the fixed frame 101, and a second crank grip 307 is movably arranged on one side of the fixed frame 101. A first reversing and speed-reducing member is arranged between the input end of the second gear 306 and the second crank grip 307; the longitudinal adjustment mechanism 2 includes a second movable frame 301 arranged between the first gear 302 and the water spray pipe 108, a sleeve is movably arranged around the rear end of the water spray pipe 108, a first movable frame 207 is movably arranged at the top of the sleeve, a first crank grip 209 is movably arranged on one side of the fixed frame 101, a limiting rod 205 is movably arranged inside the fixed frame 101, an annular slide rail 204 is arranged at the bottom of the limiting rod 205, a slider 206 is slidably arranged on the annular slide rail 204, the slider 206 is connected to the first movable frame 207, a toothed plate 201 is arranged on the annular slide rail 204, and a transmission gear 208 is movably arranged inside the fixed frame 101. A second reversing and speed-reducing member is arranged between the input end of the transmission gear 208 and the first crank grip 209; the connecting piece 4 is arranged at the rear end of the water spray pipe 108.

[0029] During operation, the device is moved to the working location by using the universal wheels 102. Subsequently, the water spray pipe 108 is connected to an external water pipe or a water gun by using the connecting piece 4. Water will enter the water spray pipe 108 through the external water pipe or the water gun and then be sprayed to the designated position. During operation, when a person stands on the pedal 103 located on one side of the fixed frame 101, the device can be fixed to the ground by using the person's own weight to ensure stability and avoid the situation of shaking and instability caused by the water's reaction force. Moreover, both the first crank grip 209 and the second crank grip 307 are on the same side as the person, and the person can easily rotate the first crank grip 209 and the second crank grip 307 while standing on the pedal 103;

[0030] The first crank grip 209 and the second crank grip 307 are manually operated components for providing rotational power. The rotational power of the second crank grip 307 is transmitted to the second gear 306 through the first reversing and reducing component, driving the second gear 306 to rotate, and transmitting power through the meshing of the second gear 306 and the first gear 302, thereby driving the water spray pipe 108 to rotate horizontally through the bearing 303. By using the meshing of the gears and the speed reduction transmission of the second reversing and reducing component, the adjustment accuracy is improved to ensure the stability of the angle adjustment of the water spray pipe 108. The bearing 303 supports the rotation of the water spray pipe 108, reducing the frictional resistance;

[0031] The rotational power of the first crank grip 209 is transmitted to the transmission gear 208 through the second reversing and reducing component, and then through the meshing of the transmission gear 208 and the toothed plate 201, the rotational motion of the transmission gear 208 is converted into the linear motion of the toothed plate 201, thereby driving the annular slide rail 204 to move up and down. The annular slide rail 204 will push and pull the rear end of the water spray pipe 108 through the slider 206, the first movable frame 207 and the sleeve, so that it swings up and down through the second movable frame 301. The sleeve can slide on the water spray pipe 108. When the water spray pipe 108 rotates horizontally, it will drive the slider 206 to slide on the annular slide rail 204 through the sleeve and the first movable frame 207, so that the annular slide rail 204 is always connected to the water spray pipe 108, realizing the adjustment of the horizontal or pitching angle at any time.

[0032] Specifically, the first gear 302 meshes with the second gear 306, and the toothed plate 201 meshes with the transmission gear 208.

[0033] Specifically, the front end of the water spray pipe 108 is connected with an extension pipe 1082 through a quick connector 1081.

[0034] The quick connector 1081 adopts an existing conventional quick connector for the quick connection between pipes. The staff adjusts the length of the water spray pipe 108 by connecting extension pipes 1082 with different lengths and calibers through the quick connector 1081. The change in caliber will cause the corresponding change in the spraying pressure. For example, extending the water spray pipe 108 and reducing the caliber will increase the spraying distance and height.

[0035] Specifically, a limit block 106 is provided on one side of the fixed frame 101. A movable plate 104 is movably arranged on one side of the fixed frame 101. A chute 105 is provided on the movable plate 104. The chute 105 is slidably connected with the limit block 106. The movable plate 104 is movably hinged with the pedal 103.

[0036] After moving the fixing frame 101 to the working location, push the movable plate 104 downward to make it slide on the fixing frame 101. During this process, the limiting block 106 will slide in the chute 105 to limit the movement range of the movable plate 104 until its bottom touches the ground. Then rotate and open the pedal 103 to make it fit the ground. At this time, stand on the pedal 103 to complete the fixation of the fixing frame 101. After the work is completed, repeat the above operations to reset it and make it leave the ground, which is convenient for the movement of the device.

[0037] Specifically, a limiting bolt 107 is movably arranged on the movable plate 104.

[0038] After adjusting the movable plate 104, rotate the limiting bolt 107 to make it move on the movable plate 104 through its threaded connection with the movable plate 104 until its front end contacts the fixing frame 101, and use the contact friction force to limit the position of the movable plate 104.

[0039] Embodiment 2: This embodiment is basically the same as the previous embodiment, the difference being that the first commutation and deceleration member includes a second worm wheel 304 arranged at the input end of the second gear 306, and a second worm 305 is arranged at the output end of the crank grip 307, and the second worm 305 meshes with the second worm wheel 304.

[0040] The second worm 305 and the second worm wheel 304 convert the vertical rotational movement of the crank grip 307 into the horizontal rotational movement of the second gear 306, and achieve deceleration and torque increase. Moreover, the transmission ratio of the second worm 305 and the second worm wheel 304 is large, the operation is labor-saving and has self-locking property, preventing the water spray pipe 108 from shifting due to the reverse impact of water pressure.

[0041] Specifically, the second commutation and deceleration member includes a first worm wheel 203 arranged at the input end of the transmission gear 208, and a first worm 202 is arranged at the output end of the crank grip 209, and the first worm 202 meshes with the first worm wheel 203.

[0042] The first worm 202 and the first worm wheel 203 convert the vertical rotational movement of the crank grip 209 into the up-and-down linear movement of the toothed plate 201, and achieve deceleration and torque increase. The operation is labor-saving and has self-locking property, preventing the water spray pipe 108 from shifting due to the reverse impact of water pressure.

[0043] Embodiment 3: This embodiment is basically the same as the previous embodiment, the difference being that the connecting member 4 includes a connecting seat 401 arranged at the rear end of the water spray pipe 108, a tapered hole 402 is arranged in the connecting seat 401, and a locking member is arranged on the connecting seat 401.

[0044] The conical hole 402 is adapted to the outer shape of the water spray gun. When the water spray gun is inserted into the conical hole 402, a sealing gasket is provided on the inner wall of the conical hole 402 to fill the gap therein and improve the sealing performance. Subsequently, the relative positions of the water spray gun and the connecting seat 401 are limited by the locking member to complete the connection operation.

[0045] Specifically, the locking member includes guide rails 403 provided on both sides of the connecting seat 401. A sliding plate 404 and a movable block 406 are slidably arranged in the guide rails 403. The sliding plate 404 and the movable block 406 are movably connected by a hinge member 405. A clamping plate 407 is provided at the rear end of the sliding plate 404. A threaded rod 408 is threadedly arranged on the connecting seat 401. The rear end of the threaded rod 408 is movably connected to the movable block 406. A nut 409 is threadedly arranged on the threaded rod 408.

[0046] Before inserting the water spray gun into the conical hole 402, rotate the threaded rod 408. Using the threaded connection relationship between the threaded rod 408 and the connecting seat 401, drive the movable block 406 together with the sliding plate 404 to move linearly. The guide rails 403 will limit and guide the positions of the sliding plate 404 and the movable block 406 until the sliding plate 404 completely disengages from the guide rails 403. At this time, the sliding plate 404 can rotate and swing on the movable block 406 through the hinge member 405, so as to open the two clamping plates 407 and expose the conical hole 402. After inserting the water spray gun, rotate the threaded rod 408 in the reverse direction. When the sliding plate 404 re-enters the guide rails 403, the clamping plates 407 will reset and close, and will be stuck at the rear flange interface of the water spray gun during the process to complete the connection and fixation of the water spray gun and the connecting seat 401. Subsequently, rotate the nut 409 until it contacts the connecting seat 401 to limit the threaded rod 408 so that it will not rotate and cause the connection to become loose.
