Abstract
The invention discloses an automatic locking method of a manual pump. The manual pump comprises a pump body, an operating pump head is mounted at the top of the pump body, and a support rotating freely is arranged on the pump body. The support is connected with a fixing hinge and a locking hinge. The fixing hinge is fixedly connected with the operating pump head in a hinge connecting manner. A lock hole is formed in the other end of the operating pump head. The tail end of the locking hinge is movably connected with the operating pump head through a pin. An inserting hole for being connected with a handle is arranged on the operating pump head. Due to the fact the support can rotate around the axis of itself, during use, the support is rotated according to use, the inserting hole of the operating pump head is located at a neutral position, and convenience and practicality are achieved. The control performance of equipment is enhanced, the mounting difficulty and risk of the equipment are reduced, the problem that the manual valve is likely to be bumped, and the equipment and the periphery are damaged is solved, the size is reduced after a handle is demounted, and packaging cost is reduced.
Description
Technical field
The present invention relates to a kind of manual pump, specifically refers to a kind of auto lock method of manual pump.
Background technology
Manual pump is exactly the displacement pump with types such as the piston type of manual operation, diaphragm types.Manual pump has a wide range of applications, and jack just belongs to one of which manual pump, and the pressing position of jack is manual pump；In fluid control systems, in especially pneumatic, hydraulic control system, manual pump is also requisite part.There is problems with current manual pump：The direction of operating of 1 manual pump is single, after installation, in the region that space is restricted, using extremely inconvenient；When not in use, or in transportation, piston mechanism is in travelling for 2 manual pumps（It is free）State, it is impossible to lock, that is, be unfavorable for protecting plunger surface and sealing, be also unfavorable for product globality and concordance；3 operation handles are non-dismountable, and overall dimensions are big, take up room, and increase Package size and packing cost；Even if 4 possess lock function, can not be with direction of operating synchronous axial system.
The content of the invention
It is an object of the invention to provide a kind of auto lock method of manual pump, strengthens the practicality of manual pump, overcomes unworkable problem in small space, meanwhile, the function that the pump housing is not locked is solved, is conducive to protecting plunger surface and sealing.
The purpose of the present invention is achieved through the following technical solutions：
A kind of auto lock method of manual pump, including the pump housing, operation pump head is installed at the top of the pump housing, the support for freely rotating is provided with the pump housing, it is connected with fixed hinge and locking hinge on the bracket, the fixed hinge mode that is connected through the hinge is fixedly connected with operation pump head, and the other end of operation pump head is provided with lockhole, the end of locking hinge is provided with the spliced eye for connecting handle by pin and operation pump head active link in operation pump head.The critical piece of manual pump is the pump housing，The pump housing is in cylinder or cylindrical shape，Lower compression leg is installed at the top of which，Operation pump head is provided with lower compression leg，Manual pump can be operated by pressing lower compression leg，The middle part of operation pump head is located at the top of lower compression leg，The mode that one end of operation pump head is connected through the hinge is fixed on one end of fixed hinge，The other end of fixed hinge is fixedly connected on support，Support is sleeved on the pump housing，Support can be rotated freely around the axis of the pump housing，But can not move along the axis of the pump housing，On support, also the mode of being connected through the hinge is installed with locking hinge，The other end of operation pump head is provided with lockhole，When manual pump or in the transportation of manual pump need not be used，Needing will operation pump head locking，Avoid operating the relative rotation between pump head and the pump housing，The end of locking hinge is locked in the lockhole of pump operation head by pin，Locking can be completed；When needing using manual pump, pin is taken out, the connection between release operation pump head and locking hinge, use by handle being installed in the spliced eye of convenient operation；As support can be rotatable around its axis, when in use, the spliced eye of operation pump head is in neutral gear position by swinging mounting as needed, convenient and practical.According to different actual demands, during operating in handle, prevent handle from coming off from spliced eye, handle generally has following two with the connected mode of operation pump head：
The first, is provided with the pin-and-hole matched with spliced eye on described operation pump head.Pin-and-hole is provided with operation pump head, and pin-and-hole is passed through spliced eye place cavity, arranges corresponding through hole, after handle is inserted, handle is fixed in spliced eye by pin, you can be fixedly connected handle with spliced eye on handle.
Second, the female thread matched with the external screw thread of handle is provided with described spliced eye.Female thread is provided with spliced eye, the external screw thread matched with the female thread of spliced eye is provided with handle, during use, handle can be fixedly mounted in the spliced eye of operation pump head by the cooperation of screw thread.
The present invention compared with prior art, has the following advantages and advantages：
A kind of auto lock method of 1 manual pump of the invention, when manual pump or in the transportation of manual pump need not be used, need to lock operation pump head, avoid operating the relative rotation between pump head and the pump housing, the end of locking hinge is locked in the lockhole of pump operation head by pin, you can complete locking；
A kind of auto lock method of 2 manual pumps of the invention, as support can be rotatable around its axis, when in use, the spliced eye of operation pump head is in neutral gear position by swinging mounting as needed, convenient and practical；
A kind of auto lock method of 3 manual pumps of the invention, the handling of equipment is not only increased, the difficulty and risk of equipment installation is also reduced, is solved and is easy to collide with, and causes the injury of equipment itself and periphery, volume is reduced after handle release, reduces packing cost；
A kind of auto lock method of 4 manual pumps of the invention, after the external world sets up power source, itself has lock function, and is unlikely to pressurized and itself comes to harm and injury to external world.
