Description

Technical Field

[0001] This utility model relates to the field of manual pump technology, specifically to a bidirectional oil-discharging manual pump. Background Technology

[0002] Manual pumps serve as power sources for systems. With the aid of matching cylinders and specialized tools, they can perform various operations such as lifting, bending, straightening, shearing, riveting, assembly, disassembly, and some construction and military operations. However, current manual pumps typically have only a single inlet and outlet, and each pump can only connect to one working device. Each pump requires a worker to operate, increasing operating costs. Furthermore, a single pump cannot control multiple devices simultaneously, reducing efficiency. Therefore, a bidirectional manual pump with oil output is proposed to reduce operating costs. Summary of the Invention

[0003] The purpose of this invention is to provide a manual pump with bidirectional oil output in order to solve the above problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a manual pump with bidirectional oil discharge, comprising an oil tank, a valve block mounted on the oil tank, a pump body movably mounted on the valve block, and a handle for driving the pump body; the valve block is provided with an oil suction channel and an oil suction chamber communicating with the oil suction port; characterized in that the valve block is provided with a first oil discharge channel and a second oil discharge channel respectively communicating with the oil suction channel and the oil suction chamber to achieve simultaneous bidirectional oil discharge; both the first oil discharge channel and the second oil discharge channel are provided with an oil discharge check valve.

[0005] Preferably, the first oil outlet channel and the second oil outlet channel are connected to the bottom of the oil suction chamber and the side of the oil suction channel, respectively.

[0006] Preferably, an oil suction guide valve is also installed in the oil suction channel.

[0007] Preferably, the first oil outlet channel and the second oil outlet channel are also respectively connected to an oil return channel connected to the oil tank.

[0008] Preferably, a return oil check valve is connected to the return oil channel.

[0009] Preferably, one end of the handle is movably connected to the valve block and simultaneously connected to the pump body to drive it to move up and down.

[0010] Preferably, the lifting handle is also equipped with a handle.

[0011] The beneficial effects of this utility model are as follows: by lifting the pump body downward, the hydraulic oil is pushed downward. The hydraulic oil simultaneously pushes open the oil outlet check valves on the first and second oil outlet channels, and oil is discharged out through the first and second oil outlet channels at the same time. This allows the manual pump to control two devices to work at the same time, thereby improving the efficiency of use and reducing the cost of use. Attached Figure Description

[0019] The following description, in conjunction with the accompanying drawings, further illustrates the bidirectional oil-discharging manual pump of this utility model.

[0020] It should be noted that all directional indications in the embodiments of the present invention, such as up, down, left, right, front, back, etc., are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indication will also change accordingly.

[0021] See appendix Figure 1-6As shown, this embodiment of a bidirectional oil-discharging manual pump includes an oil tank 1, a valve block 2 mounted on the oil tank 1, a pump body 3 movably mounted on the valve block 2, and a handle 4 for driving the pump body 3. The valve block 2 is provided with an oil suction channel 201 and an oil suction chamber 202 communicating with the oil suction port. The valve block 2 is characterized by having a first oil discharge channel 203 and a second oil discharge channel 204 respectively communicating with the oil suction channel 201 and the oil suction chamber 202 to achieve simultaneous bidirectional oil discharge. Both the first oil discharge channel 203 and the second oil discharge channel 204 are provided with oil discharge check valves 205. By using the handle 4 to drive the pump body 3 downwards, hydraulic oil is pushed downwards, simultaneously opening the oil discharge check valves 205 on the first oil discharge channel 203 and the second oil discharge channel 204. Oil is discharged simultaneously through the first oil discharge channel 203 and the second oil discharge channel 204, allowing the manual pump to control two devices simultaneously, thereby improving work efficiency and reducing operating costs.

[0022] See appendix Figure 2-3 As shown, the first oil outlet channel 203 and the second oil outlet channel 204 are respectively connected to the bottom of the oil suction chamber 202 and the side of the oil suction channel 201; an oil suction check valve 206 is also installed in the oil suction channel 201; when the pump body 3 moves upward, the hydraulic oil in the oil tank 1 pushes the oil suction check valve 206 through the oil suction channel 201 into the oil suction chamber 202; when the pump body 3 presses downward, the oil suction check valve 206 is closed to prevent the hydraulic oil from flowing back to the oil tank 1.

[0023] See appendix Figure 2-5 As shown, the first oil outlet channel 203 and the second oil outlet channel 204 are respectively connected to the return oil channel 207 connected to the oil tank 1; the return oil channel 207 is connected to the return oil check valve 208; when returning oil, the hydraulic oil pushes open the return oil check valve 208, so that the hydraulic oil returns directly to the oil tank 1 through the return oil channel 207, thereby facilitating the return of hydraulic oil.

[0024] See appendix Figure 1 As shown, one end of the lifting handle 4 is movably connected to the valve block 2 and simultaneously connected to the pump body 3 to drive it to move up and down; a handle 5 is also installed on the lifting handle 4; the lifting handle 4 moves up and down by the handle 5, and the lifting handle 4 drives the pump body 3 to move up and down to suck and press oil, thereby facilitating the pump body 3 to move up and down to suck and press oil, and at the same time, the handle 5 increases the length of the lifting handle 4, improving the convenience of use.

[0025] In the working process of this utility model, the handle 5 drives the lifting handle 4 to move upward, and the lifting handle 4 drives the pump body 3 to move upward along the oil suction chamber 202. The hydraulic oil in the oil tank 1 pushes open the oil suction check valve 206 and enters the oil suction chamber 202 through the oil suction channel 201. Then, the handle 5 drives the lifting handle 4 to move downward, and the lifting handle 4 drives the pump body 3 to move downward along the oil suction chamber 202 to press the hydraulic oil. The hydraulic pressure pushes the oil suction check valve 206 to close. At the same time, the pressure of the hydraulic oil pushes open the oil outlet check valves 205 on the first oil outlet channel 203 and the second oil outlet channel 204. The hydraulic oil passes through the oil outlet check valves 205 and is delivered to the corresponding equipment for use through the first oil outlet channel 203 and the second oil outlet channel 204 respectively. This allows the manual pump to connect to two devices that are working at the same time, improving efficiency and reducing the cost of use.

[0026] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
