According to the utility model, oil outlet pipelines can be rapidly and detachably connected.
Description
Technical field
The utility model relates to pump field, particularly mechanical pump.
Background technique
Blade mechanical pump is mainly made up of parts such as cylindrical cavity stator, eccentric rotor, blade, spring, top cover and outlet valves at present, and cavity is whole to be placed in fuel tank.Blade mechanical pump needs regular more changing oil, while changing oily in fuel tank, conventionally utilize the directly oil discharge of a straight pipeline, so very portion is beneficial to the cleaning of oil-drain pipe, although there is the mechanical pump of being convenient to clean oil extraction pipeline at present, the oil extraction pipeline of this mechanical pump is divided into oil outlet tube, connecting head, send oil pipe, and the Placement between them is and removably connects.But this general employing that removably connect is threaded or bolt connection, when installation and removal, wastes time and energy, and reduced efficiency.
Model utility content
The purpose of this utility model is to provide the mechanical pump that can connect fast between the detachable and each assembly of a kind of oil-drain pipe.
Realize the technical solution of the utility model as follows: mechanical pump, comprise the pump housing and the oil outlet tube of being located at pump housing below, this oil outlet tube is provided with an one-way valve, oil outlet tube lower end is provided with a connecting head, described connecting head lower end is provided with one and send oil pipe, is installed with a seal ring between described oil outlet tube and connecting head, and described oil outlet tube is connected by described connecting head with sending oil pipe, in the interior sidewall surface of described seal ring top connecting head, be provided with shackle member, in shackle member, be provided with claw.
Upwards be provided with pier shoulder described oil outlet tube week, this pier is takeed between one-way valve and seal ring, and when described claw withstands the pier shoulder on oil outlet tube, claw is to centroclinal 12 °.
One end of described shackle member is provided with the buckle for fixed card fitting.
Described connecting head lower end with send oil pipe for being threaded.
The beneficial effects of the utility model are: in the interior sidewall surface due to described seal ring top connecting head, be provided with shackle member, in shackle member, be provided with claw, upwards be provided with pier shoulder oil outlet tube week, this pier is takeed between one-way valve and seal ring, in oil outlet tube inserts connecting head time, shackle member and claw firmly block pier shoulder; Wherein preferred, when described claw withstands the pier shoulder on oil outlet tube, claw is to centroclinal 12 °; One end of shackle member is provided with the buckle for fixed card fitting, and shackle member is fixed on connecting head; Again due to connecting head lower end with send oil pipe for being threaded, removably connect, convenient clean and change.
Brief description of the drawings
By the detailed description below in conjunction with accompanying drawing, the utility model is aforesaid will be become apparent with other object, feature and advantage.
Wherein: Fig. 1 is the utility model structural representation;
In accompanying drawing, 1 is the pump housing, and 2 is oil outlet tube, and 3 is one-way valve, and 4 is connecting head, and 5 for sending oil pipe, and 6 is seal ring, and 7 is shackle member, and 8 is claw, and 9 is pier shoulder, and 10 is buckle.
Embodiment
Shown in Figure 1, mechanical pump, comprise the pump housing 1 and the oil outlet tube 2 of being located at pump housing below, this oil outlet tube is provided with an one-way valve 3, oil outlet tube lower end is provided with a connecting head 4, described connecting head lower end is provided with one and send oil pipe 5, between described oil outlet tube and connecting head, be installed with a seal ring 6, described oil outlet tube is connected by described connecting head with sending oil pipe, upwards be provided with pier shoulder 9 described oil outlet tube week, this pier is takeed between one-way valve and seal ring, in the interior sidewall surface of described seal ring top connecting head, be provided with shackle member 7, in shackle member, be provided with claw 8, when described claw withstands the pier shoulder on oil outlet tube, claw is to centroclinal 12 °.Described claw is uniform to be distributed in connecting head around, and one end of described shackle member is provided with the buckle 10 for fixed card fitting.Described shackle member is plastics fastener or metal fastener, and described buckle is clamp button of the spring.Buckle is fixed on shackle member in connecting head, prevents that shackle member from dropping, and described connecting head lower end is threaded and send oil pipe.
Mechanical pump in the time changing oily in fuel tank, by one-way valve opens, the oil in fuel tank successively by oil outlet tube, connecting head, send oil pipe to be discharged from; Owing to adopting being connected of claw and pier shoulder between oil outlet tube and connecting head, connecting head is threaded with sending oil pipe employing, all detachable, therefore be convenient to clean oil outlet tube, connecting head, send oil pipe.And owing to having adopted claw and coordinating that pier is takeed on, need not re-use and be threaded or the mode such as bolt connection, only oil outlet tube need be inserted to connecting head, the resiliently deformable of the shackle member arranging in connecting head while arriving at pier shoulder position is fixed oil outlet tube, and claw in shackle member withstands pier shoulder, oil outlet tube is firmly blocked.Greatly facilitate people's operation, and connection speed is fast, efficiency is high.
The utility model is not limited to described embodiment; those skilled in the art is not departing from spirit of the present utility model openly in scope; still can do some corrections or change; for example connecting head be connected send oil pipe except adopt be threaded; can certainly adopt being connected of claw in shackle member, shackle member and pier shoulder etc., therefore the scope that rights protection scope of the present utility model limits with claims is as the criterion.
