[0020] Below we further illustrate the electric hydraulic horizontal jack described in the utility model in conjunction with the accompanying drawings.

[0021] It should be noted that all directional indications such as up, down, left, right, front, back... in the embodiments of the utility model are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture as shown in the accompanying drawings. If the specific posture changes, the directional indication will also change accordingly.

[0022] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation" and the like shall be used in a broad sense. For example, "fixation" may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be a direct connection or an indirect connection through an intermediate medium; it may be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] See also Figure 1-6 As shown in, an electric hydraulic horizontal jack comprises a jack body 1 and a handle assembly 2 connected to the jack body 1; the characteristic is that the handle assembly 2 comprises a click handle 21 movably mounted on the jack body 1, a handle tube 22 detachably mounted on the click handle 21, and a handle 23 mounted on the handle tube 22; the handle 23 is mounted with a control circuit board 4, a control switch 41 and a power switch 42 electrically connected to the control circuit board 4, the female plug 32 is connected to the control circuit board 4 through a line, and the male plug 31 is connected to the electric control device in the jack body through a line; the handle 23 is also mounted with a battery pack seat 5, a battery pack terminal board 51 electrically connected to the control circuit board 4 is mounted in the battery pack seat 5, and a battery pack 52 detachably mounted in the battery pack seat 5 and electrically connected to the battery pack terminal board 51;

[0024] The electric control device in the jack body 1 includes a motor for driving the electric pump to start and an electromagnet for opening the oil drain valve, and the male plug 31 is connected to the motor and the electromagnet through a line;

[0025] The battery pack 52 is connected to the control circuit board 4 through the battery pack terminal board 51, and is used to supply power to the control circuit board 4 and the electronic control components on the jack body 1;

[0026] By installing the aviation plug 3 on the snap handle 21 and the handle tube 22, and installing the female plug 32 and the male plug 31 of the aviation plug 3 on the handle tube 22 and the snap handle 21 respectively, the handle tube 22 can be removed from the snap handle 21 when the jack is packaged, thereby reducing the packaging volume of the jack and reducing the transportation cost. When the handle tube 22 is installed on the snap handle 21 for reuse, the male plug 31 and the female plug 32 can be plugged together to complete the electrical connection. In addition, the disassembly and assembly and connection of the snap handle 21 and the handle tube 22 are simple, convenient and quick.

[0027] In one embodiment, the handle assembly 2 further comprises a threaded connection sleeve 6 disposed on the click handle 21, and a nut 61 movably mounted on the handle tube 22 for connecting with the threaded connection sleeve 6 to lock the handle tube 22 on the click handle 21 and prevent the male plug 31 and the female plug 32 from being easily disengaged;

[0028] The handle tube 22 and the press handle 21 are also provided with an aviation plug 3 for preliminarily connecting the handle tube 22 and the press handle 21 and for connecting the lines. The aviation plug 3 includes a male plug 31 connected to the press handle 21 and a female plug 32 connected to the handle tube 22 and adapted to the male plug 31;

[0029] The female plug 32 is provided with a limit platform 62 which serves to limit and block the position of the nut 61;

[0030] The female plug 32 is provided with a limit platform 62 which serves as a limit and blocking role for the position of the nut 61; when the male plug 31 and the female plug 32 are plugged in, the nut 61 is screwed onto the threaded connection sleeve 6 through a thread. When tightening, the nut 61 applies force to the limit platform 62 of the female plug 32, thereby locking the female plug 32 and the male plug 31, avoiding the female plug 32 and the male plug 31 from being disengaged during use, resulting in the disconnection of the circuit and the disconnection between the handle tube 22 and the press handle 21, thereby completing the locking connection between the handle tube 22 and the press handle 21.

[0031] In one embodiment, the jack body 1 comprises a frame 11 , an oil pump assembly 12 mounted on the frame 11 , and an arm assembly 13 mounted on the frame 11 and connected to the oil pump assembly 12 .

[0032] In one embodiment, the control switch 41 is a patch switch, including an upward switch for controlling the jack to rise and a downward switch for controlling the jack to descend.

[0033] When the utility model is in use:

[0034] When the hand assembly is installed and connected, the end of the handle tube 22 with the female plug 32 installed is inserted into the threaded connection sleeve 6. When inserting, the female plug 32 is aligned with the male plug 31. During the insertion process, the plugging is completed until the limit platform 62 contacts the end of the threaded connection sleeve 6. Then, the nut 61 is moved to the threaded connection sleeve 6 and rotated. After the nut 61 and the threaded connection sleeve 6 are tightened through the thread, the nut 61 presses the limit platform 62. At this time, the connection and installation of the handle assembly 2 are completed, and the electrical connection between the electronic control device in the jack and the control circuit board 4 is completed at the same time;

[0035] When in use, the operator can control the motor or electromagnet to start by driving the corresponding control switch 41. When the motor starts, the jack is lifted. When the electromagnet starts, the oil drain valve is opened to return oil and the jack is lowered.

[0036] When the handle assembly 2 needs to be disassembled, the nut 61 is first loosened, and then the handle tube 22 is pulled outward. The handle tube 22 drives the female plug 32 to move outward until the female plug 32 is disconnected from the male plug 31, and the disassembly is completed. After disassembly, the volume of the entire jack can be reduced, thereby reducing the occupied space and the packaging volume.

[0037] The protection scope of the present utility model is not limited to the above embodiments and their variations. Conventional modifications and replacements made by those skilled in the art based on the contents of this embodiment all fall within the protection scope of the present utility model.
