Abstract
The utility model discloses a multi-position operated self-locking manual pump. The manual pump comprises a pump body, wherein an operation pump head is installed at the top of the pump body; one end of the operation pump head is fixedly hinged with the pump body; at least two insertion holes in different directions are formed in the operation pump head; and a locking hole is formed in the other end of the operation pump head and is matched with a locking hinge on the pump body. The manual pump can be operated in multiple positions in a narrow space, which improves the practicability; when not in use or in the conveying process, the manual pump can be locked as long as the tail end of the locking hinge is locked in the locking hole of the operation pump head through a pin; the pump installation difficulty and risk are reduced, the problem that the pump self and the periphery of the pump are damaged caused by possible collision is solved, and the pump is reduced in size when a handle is disassembled, which reduces the packaging cost.
Description
Technical field
The utility model relates to a kind of hand pump, but specifically is meant a kind of hand pump of multi-position action self-locking.
Background technique
Hand pump is exactly the displacement pump of types such as the piston type, diaphragm type with manual operation.Hand pump has a wide range of applications, and jack just belongs to wherein a kind of hand pump, and the power source of jack is hand pump; In the hand liquid control system, hand pump parts that also are absolutely necessary in pneumatic, the system of surging especially.There is following problem in present hand pump: the direction of operating of 1 hand pump is single, in the zone that the space is restricted, uses extremely inconvenient; 2 hand pumps are not when using, and perhaps in the transportation process, piston mechanism is in (dissociating) state that moves about, and can not lock, and promptly is unfavorable for protecting plunger surface and sealing, also is unfavorable for product integrity and conformity; 3 operating grips are on-dismountable, and boundary dimension is big, take up room, and increase Package size and packing cost.Even 4 possess lock function, can not rotate synchronously with direction of operating.
The model utility content
But the purpose of the utility model is to provide a kind of hand pump of multi-position action self-locking, strengthens the practicability of hand pump, overcomes unworkable problem in the small space, simultaneously, solves the function that the pump housing does not have lock, helps protecting plunger surface and sealing.
The purpose of the utility model realizes through following technical proposals:
But a kind of hand pump of multi-position action self-locking; Comprise the pump housing; At the top of the pump housing operation pump head is installed, an end of operation pump head is connected on the pump housing through fixed hinge, is provided with the spliced eye of two different direction on the said operation pump head at least; The other end at the operation pump head is provided with lockhole, and the pump housing is provided with the locking hinge that is complementary with lockhole.The critical piece of hand pump is the pump housing, and the cylindrical or cylindrical shape of the pump housing is equipped with compression leg down at its top; Following compression leg is provided with the operation pump head, can operate hand pump through pressing down compression leg, and the operation pump head is provided with a plurality of spliced eyes; Can handle installation in spliced eye, the motive force of growth arm extends to the operating position outside the space of installation; Be convenient to operation, a plurality of spliced eyes handle of all can pegging graft is in narrow space; A plurality of positions all can be operated, and have strengthened the practicability of hand pump, and the middle part of operation pump head is positioned at the top of compression leg down; The mode that one end of operation pump head is connected through the hinge is fixed on an end of fixed hinge, and the other end of fixed hinge is fixedly connected on the pump housing, and also the mode of being connected through the hinge is installed with locking hinge on the pump housing; The other end at the operation pump head is provided with lockhole, when not using in hand pump or the transportation process at hand pump, needs to operate the pump head locking; Avoid operating relatively rotating between the pump head and the pump housing, the end of locking hinge is fixed in the lockhole of operation pump head through pin lock, can accomplish locking; When needs use hand pump, the taking-up of will pinning, being connected between releasing operation pump head and the locking hinge installed handle and can be used in the spliced eye of easy-to-operat.
Described operation pump head is provided with the pin-and-hole that matees one by one with spliced eye.Further say,, prevent that handle from coming off from spliced eye in lever operated process; Can on the position of each spliced eye on the operation pump housing, pin-and-hole be set; Corresponding through hole is set on handle, after handle is inserted, handle is fixed in the spliced eye through pin; Also can take other fixing means, for example spliced eye is connected through screw-thread fit with handle.
Spliced eye is three on the said operation pump head.Say that further the quantity of spliced eye is practical in the time of three, three spliced eyes lay respectively at two sides and the top of operation pump head, can be in the scope of broad operating grip, strengthened practicability.
The utility model compared with prior art has following advantage and beneficial effect:
But the hand pump of a kind of multi-position action self-locking of 1 the utility model, the operation pump head is provided with a plurality of spliced eyes, can handle installation in spliced eye; The motive force of growth arm extends to the operating position outside the space of installation, is convenient to operation; A plurality of spliced eyes handle of all can pegging graft; In narrow space, a plurality of positions all can be operated, and have strengthened the practicability of hand pump;
But the hand pump of a kind of multi-position action self-locking of 2 the utility model; Also the mode of being connected through the hinge is installed with locking hinge on the pump housing, is provided with lockhole at the other end of operating pump head, when not using in hand pump or the transportation process at hand pump; Need to operate the pump head locking; Avoid operating relatively rotating between the pump head and the pump housing, the end of locking hinge is fixed in the lockhole of operation pump head through pin lock, can accomplish locking;
But the hand pump of a kind of multi-position action self-locking of 3 the utility model; Not only strengthened the handling of equipment, also reduced equipment mounting hardness and risk, solved and be easy to collide with and cause equipment itself and peripheral injury; Reduce volume after the handle dismounting, reduced packing cost;
But the hand pump of a kind of multi-position action self-locking of 4 the utility model, after the external world set up power source, itself had lock function, and was unlikely to pressurized and self comes to harm and to external world injury.
