Description

Technical Field

[0001] This utility model relates to the field of jacks, specifically a vertical jack that facilitates the replacement of the throttle valve. Background Technology

[0002] Vertical jacks are commonly used in factories, warehouses, auto repair shops, bridges, docks, transportation, and construction projects due to their small size, ease of operation, and portability. However, in existing vertical jacks, the throttle valve, which is located inside the base and is part of the return oil line, can become damaged over time. When replacing it, the entire outer casing must be removed from the base, and then the entire base must be replaced with a new one. This process is inconvenient and costly. Furthermore, some users prefer to replace the entire jack due to the hassle of disassembly. Therefore, a vertical jack with a throttle valve that is easy to replace has been proposed. Utility Model Content

[0003] The main purpose of this utility model is to provide a solution that can effectively address the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a vertical jack that facilitates the replacement of a throttle valve, comprising a housing, an oil cylinder disposed within the housing, a base disposed at the bottom of the housing, an oil pump component disposed on the base, and a handle for draining oil, wherein the oil pump component is provided with a movable handle; characterized in that: the base is provided with a throttle valve component that can be easily disassembled, wherein the throttle valve component includes a throttle valve, a screw connected to the throttle valve, and a copper gasket for sealing.

[0005] Preferably, the hydraulic cylinder includes a cylinder body disposed inside the outer casing, a large piston rod disposed inside the hydraulic cylinder, and an oil reservoir disposed outside the cylinder body.

[0006] Preferably, the oil pump component includes a pump body seat on a base, a pump body on the pump body seat, a small piston rod in the pump body, and a pump core on the small piston rod.

[0007] Preferably, the handle is provided with an oil drain valve, which is also located in the base and connected to the throttle valve.

[0008] Preferably, the throttle valve is also connected to the hydraulic cylinder.

[0009] This utility model has the following advantages: by setting an easy-to-replace throttle valve component on the base, the operator can remove the throttle valve from the base for replacement by removing the screws and copper washer. The operation is simple and convenient, and at the same time, it avoids the need to replace the entire base due to damage to the throttle valve, thus saving maintenance costs.

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] like Figure 1-4 As shown, a vertical jack for easy replacement of a throttle valve includes a housing 1, an oil cylinder 2 disposed within the housing, a base 3 disposed at the bottom of the housing 1, an oil pump component 5 disposed on the base 3, and a handle 6 for draining oil. The oil pump component 5 is provided with a movable handle 4. The jack is characterized in that: the base 3 is provided with a throttle valve component 7 that can be easily disassembled. The throttle valve component 7 includes a throttle valve 71, a screw 72 connected to the throttle valve 71, and a copper gasket 73 for sealing.

[0017] By providing an easily replaceable throttle valve component 7 on the base, the operator can remove the throttle valve 71 from the base 3 for replacement by removing the screws 72 and the copper washer 73. The operation is simple and convenient, and at the same time, it avoids the need to replace the entire base due to damage to the throttle valve, thus saving maintenance costs.

[0018] In one embodiment, the hydraulic cylinder 2 includes a cylinder body 21 disposed within the outer casing 1, a large piston rod 22 disposed within the hydraulic cylinder 2, and an oil reservoir 23 disposed outside the cylinder body 21; the oil pump component 5 includes a pump body seat 51 disposed on the base 3, a pump body 52 disposed on the pump body seat 51, a small piston rod 53 disposed within the pump body 52, and a pump core 54 disposed on the small piston rod 53; the handle 6 is provided with an oil drain valve 61, and the oil drain valve 61 is also disposed within the base 3 and connected to a throttle valve 71; the throttle valve 71 is also connected to the hydraulic cylinder 2.

[0019] In the working process of this utility model, first, place the jack under the heavy object, put the extended handle on the handle 4, lift the handle 4, so that the pump core 53 in the oil pump component 5 drives the small piston rod 53 upward, and the hydraulic oil in the oil reservoir 23 enters the pump body 52 through the oil circuit to open the steel ball on the one-way valve. Then press the handle 4, the small piston rod 53 moves downward, and the hydraulic oil in the pump body 52 is pressed into the oil cylinder 2 through the one-way valve. After the oil cylinder 2 is under pressure, it drives the large piston rod 22 to lift upward. After repeatedly pressing the handle 4, the heavy object is lifted to the required height. After completion, rotate the handle 6, so that the oil drain valve 61 is pushed out in the direction of the handle 6, so that the steel ball on the oil drain valve 61 pushes upward, the large piston rod 22 descends, the hydraulic oil opens the throttle valve 71 along the oil circuit, and then returns to the oil reservoir 23 through the oil drain valve 61, so that the large piston rod 22 falls back to the initial state.

[0020] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
