[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-5 The utility model provides a technical solution: an adjustable manual pump pressure rod, including a pump body 1, a pressure rod is hinged on the upper end surface of the front side of the pump body 1, the pressure rod includes a hollow tubular cavity 2, a telescopic rod 8 is inserted into the rear side of the tubular cavity 2, a placement sleeve 7 is fixedly connected to the outer circumference of the rear side of the tubular cavity 2, and a locking component is rotatably connected to the placement sleeve 7.

[0023] First, place the hand pump in a suitable position. When the hand pump needs to be pressurized, the position of the telescopic rod 8 in the tubular cavity 2 is adjusted according to the needs of different staff members. After the adjustment is completed, the position of the telescopic rod 8 in the tubular cavity 2 is fixed by a locking component, so that the staff can pressurize the hand pump more easily. The hand pump in the prior art is a manual double-acting hydraulic pump, which is mainly composed of a pump body, a pressure rod, a valve group, and a piston. When the pressure rod is pushed downward, the piston in the pump body will be forced to drop, so that the liquid in the pump body is compressed. The liquid pressure will increase during the compression process, and then the compressed liquid will flow out of the pump body through the valve group and be transported to the hydraulic equipment. Here, by changing the position of the telescopic rod 8 in the official cavity 2, the length of the pressure rod is increased, and it is more labor-saving for people to stand up.

[0024] The locking component includes a rotating shaft 10 that is rotatably connected to the middle part of the upper side of the placement sleeve 7, an incomplete gear 16 is fixedly provided on the middle side of the rotating shaft 10, a rack 9 is meshingly connected to the lower side of the incomplete gear 16, the rack 9 is fixedly connected to the upper end surface of the telescopic rod 8, an adjusting rod 6 is fixedly connected to the upper end of the incomplete gear 16, a ratchet 11 is fixedly provided on the right end of the rotating shaft 10, a ratchet rod 14 is meshingly connected to the upper side of the ratchet 11, a slide groove 15 is opened in the middle part of the ratchet rod 14, a limiting rod 12 is inserted in the slide groove 15, the limiting rod 12 is fixedly connected to the placement sleeve 7, a tension spring 5 is fixedly connected to the upper end surface of the limiting rod 12, and the upper end of the tension spring 5 is fixedly connected to the upper wall of the slide groove 15.

[0025] The ratchet wheel 11 and the ratchet rod 14 are meshed and connected to each other, so that the rotating shaft 10 can be rotated in one direction. Figure 3 What is shown in the figure is the state of the telescopic rod 8 in the tubular cavity 2 after adjustment. When it is necessary to adjust the position of the telescopic rod 8 in the tubular cavity 2, the ratchet rod 14 is pulled up to disengage the ratchet rod 14 from the ratchet wheel 11. At this time, the unidirectional rotation of the rotating shaft 10 is released, and the adjusting rod 6 is reversed to disengage the incomplete gear 16 from the rack 9. Then, the telescopic rod 8 is moved backward and the ratchet rod 14 is loosened. Under the action of the tension spring 5, the ratchet rod 14 is engaged with the ratchet wheel 11. After the telescopic rod 8 is moved backward to a suitable position, the adjusting rod 6 is rotated forward to engage the incomplete gear 16 with the rack 9. Due to the engagement of the ratchet rod 14 with the ratchet wheel 11, the rotating shaft 10 is rotated unidirectionally. Due to the engagement of the incomplete gear 16 with the rack 9, the position of the telescopic rod 8 in the tubular cavity 2 after movement is fixed.

[0026] The limiting rod 12 and the sliding groove 15 are both square.

[0027] The upper end of the ratchet rod 14 is fixedly connected with a pull ring 13 .

[0028] By moving the pull ring 13 upward, the ratchet rod 14 is disengaged from the ratchet wheel 11 , thereby facilitating the retractable rod 8 to be retracted to a suitable position in the tubular cavity 2 .

[0029] The front and rear sides of the lower end of the pump body 1 are fixedly connected with a front support base and a rear support base 4 .

[0030] The front support base and the rear support base 4 play a supporting role.

[0031] The rear end of the telescopic rod 8 is fixedly connected with a handle 3 .

[0032] The handle 3 can be used to adjust the position of the upper and lower sides of the tubular cavity 2.

[0033] When the utility model is in use, the hand pump is first placed in a suitable position. When the hand pump needs to be pressurized, the position of the telescopic rod 8 in the tubular cavity 2 is adjusted according to the needs of different staff members. The position of the telescopic rod 8 in the tubular cavity 2 is fixed by a locking component after adjustment, so that the staff can save effort when pressurizing the hand pump.

[0034] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
