Description
Technical Field
[0001] The utility model relates to the technical field of hydraulic pumps, in particular to a manual hydraulic pump. Background Art
[0002] Manual hydraulic pumps are a simple and convenient hydraulic power source that is widely used in many fields such as shipbuilding industry, coal mining machinery, petrochemical, metallurgy, electricity, and heavy machinery. Manual hydraulic pumps are mainly divided into two types: lever piston cylinder type and crank plunger type.
[0003] However, the relevant manual hydraulic pump still has some shortcomings when in use. First, the pressure rod is not conducive to disassembly and replacement, which reduces the effect of use. At the same time, the pressure rod is connected to the pump body, which increases the volume and is not conducive to storage. When the pump body is transported, it is inconvenient to lock the pressure rod, which makes the pressure rod easy to move and affect transportation. Therefore, we propose a manual hydraulic pump to solve the above problems. Utility Model Content
[0004] The utility model aims to provide a manual hydraulic pump, which has a pressure rod that is convenient for disassembly, assembly and replacement, thereby improving the use effect. At the same time, the disassembly of the pressure rod is conducive to reducing the overall volume of the hydraulic pump body, which is convenient for storage. When the hydraulic pump body is transported, the pressure rod and the sleeve rod can be locked, so that the pressure rod will not deflect or shake, thereby affecting normal transportation.
[0005] The above-mentioned technical objective of the utility model is achieved through the following technical scheme: it comprises a manual hydraulic pump body and a pressure rod, the top of the hydraulic pump body is fixedly connected to two support plates, the same sleeve rod is rotatably connected between the two support plates, a disassembly and replacement mechanism is arranged between the sleeve rod and the pressure rod, the outer side of the sleeve rod is rotatably connected to a piston rod, the piston rod is slidably sleeved in the hydraulic pump body, the top of the hydraulic pump body is fixedly connected to a stabilizing plate, the bottom of the sleeve rod is fixedly connected to a connecting plate, a locking mechanism for fixing the sleeve rod is arranged between the stabilizing plate and the connecting plate, one end of the hydraulic pump body is fixedly connected to a connecting pipe, the connecting pipe is provided with a hydraulic gauge, and the bottom of the hydraulic pump body is fixedly connected to two support seats.
[0006] The utility model is further configured as follows: a slot is provided at one end of the sleeve rod, the disassembly and replacement mechanism includes an insertion rod fixedly connected to one end of the pressure rod, the insertion rod is movably inserted in the slot, a through slot is provided on the top of the insertion rod, a return spring is provided in the through slot, both ends of the return spring are fixedly connected to slides, the outer sides of the two slides are fixedly connected to clamping rods, the top and bottom of the sleeve rod are provided with clamping holes, and the two clamping rods are movably clamped in the corresponding clamping holes respectively.
[0007] By adopting the above technical solution, when it is necessary to remove the pressure rod, the two clamping rods are pressed inwardly so that the two clamping rods are disengaged from the clamping holes without fixing the insertion rod. At this time, the personnel can pull the pressure rod and the insertion rod out of the sleeve rod to disassemble and replace the pressure rod. At the same time, when not in use, the overall volume of the hydraulic pump body can be reduced for storage. When in use, the two clamping rods are pressed to retract them into the through groove and squeeze the reset spring, and then the insertion rod is inserted into the slot. When fully inserted, the clamping rod is aligned with the clamping hole. Under the elastic force of the reset spring, the two clamping rods extend out and clamp into the corresponding clamping holes.
[0008] The utility model is further configured as follows: the two slide plates are both slidably sleeved in the through groove.
[0009] By adopting the above technical solution, it is helpful to guide the skateboard so that its movement is more stable and smooth.
[0010] The utility model is further configured as follows: a rubber sleeve is provided on the outer fixing sleeve of the pressure rod.
[0011] By adopting the above technical solution, people can press the pressure rod more comfortably.
[0012] The utility model is further configured as follows: a refueling port is fixedly connected to the top of the hydraulic pump body, and a sealing cover is provided on the outer thread sleeve of the refueling port.
[0013] By adopting the technical solution, it is convenient to unscrew the sealing cover so as to add oil or drain oil.
[0014] The utility model is further configured as follows: the locking mechanism includes a lock hook slidably sleeved in a stabilizing plate, a limit plate slidably sleeved on the outer side of the lock hook, a transverse spring movably placed between the stabilizing plate and the limit plate, the transverse spring is sleeved on the outer side of the lock hook, a lock hole is opened on the front side of the connecting plate, and the lock hook is movably engaged in the lock hole.
[0015] By adopting the above technical solution, when in use, the lock hook is pulled from the rear side so that the lock hook is disengaged from the lock hole backwards without fixing the connecting plate and the sleeve rod. At this time, the transverse spring is compressed. At this time, the personnel rotates the lock hook to the lower left and then releases the lock hook. At this time, under the elastic force of the transverse spring, the lock hook automatically resets forward. When carrying, when the sleeve rod and the pressure rod need to be locked, the sleeve rod and the pressure rod are pressed downwards, the lock hook is pulled backwards, and the lock hook is rotated upwards so that the upper end of the lock hook is aligned with the lock hole, and then the lock hook is released. At this time, under the elastic force of the transverse spring, the lock hook moves forward and is locked in the lock hole, thereby locking the connecting plate, the sleeve rod and the pressure rod to prevent the pressure rod from deflecting and shaking and affecting normal transportation.
[0016] The utility model is further configured as follows: a through hole is opened on the front side of the stabilizing plate, and the locking hook is slidably sleeved in the through hole.
[0017] By adopting the above technical solution, it is helpful to guide the lock hook so that its movement is more stable and smooth.

[0019] By adopting the above technical solution, through the setting of the external thread and the nut, the nut can be tightened backwards after long-term use. The backward movement of the nut drives the backward movement of the limit plate. The backward movement of the limit plate can squeeze the transverse spring to increase its elasticity, thereby avoiding the elasticity of the transverse spring becoming smaller due to long-term use and affecting the locking effect. At the same time, the nut can be unscrewed to disassemble, replace and maintain the lock hook and the transverse spring, thereby greatly improving the use effect.
[0020] The beneficial effects of the utility model are:
[0021] 1. When the pressure rod is disassembled, the two clamping rods are pressed inwardly to make the two clamping rods disengage from the clamping holes without fixing the insertion rod. At this time, the personnel can pull the pressure rod and the insertion rod out of the sleeve rod to disassemble and replace the pressure rod. At the same time, when not in use, the overall volume of the hydraulic pump body can be reduced for storage. When in use, the two clamping rods are pressed to retract them into the through grooves and squeeze the reset springs, and then the insertion rod is inserted into the slots. When fully inserted, the clamping rods are aligned with the clamping holes. Under the elastic force of the reset springs, the two clamping rods are extended and clamped in the corresponding clamping holes to fix the pressure rod.
[0022] 2. When the utility model is in use, the lock hook is pulled backward from the phase side so that the lock hook is disengaged from the lock hole backward without fixing the connecting plate and the sleeve rod. At this time, the transverse spring is compressed. At this time, the personnel rotates the lock hook to the lower left and then releases the lock hook. At this time, under the elastic force of the transverse spring, the lock hook automatically resets forward. When it is necessary to lock the sleeve rod and the pressure rod during transportation, the sleeve rod and the pressure rod are pressed downward, the lock hook is pulled backward, and the lock hook is rotated upward so that the upper end of the lock hook is aligned with the lock hole, and then the lock hook is released. At this time, under the elastic force of the transverse spring, the lock hook moves forward and is locked in the lock hole, thereby locking the connecting plate, the sleeve rod and the pressure rod to prevent the pressure rod from deflecting and shaking and affecting normal transportation.
[0023] 3. The utility model is provided with external threads and nuts. When used for a long time, the nut can be tightened backwards. The backward movement of the nut drives the backward movement of the limit plate. The backward movement of the limit plate can squeeze the transverse spring to increase its elasticity, thereby preventing the elasticity of the transverse spring from decreasing due to long-term use and affecting the locking effect. At the same time, the nut can be unscrewed to disassemble, replace and maintain the lock hook and the transverse spring, thereby greatly improving the use effect. BRIEF DESCRIPTION OF THE DRAWINGS
