Abstract
The utility model discloses an external-hanging-type double-layer damper for an electronic injection fuel pump. The external-hanging-type double-layer damper for the electronic injection fuel pump comprises the electronic injection fuel pump, a lower movable frame, a lower fixing ring, an installation plate, a compaction fixing clasp, a damping spring, a damping pad, an upper fixing ring and an upper movable frame, wherein the upper fixing ring and the lower fixing ring are mutually symmetrical; the damping spring is installed in a hole formed between the lower fixing ring and the upper fixing ring; the upper movable frame is arranged at one side of the upper fixing ring; the lower movable frame and the installation plate are respectively positioned at two sides of the lower fixing ring; the compaction fixing clasp is arranged on the installation plate; and the damping pad is arranged between the electronic injection fuel pump and the lower movable frame. With the adoption of the external-hanging-type double-layer damper for the electronic injection fuel pump, an intelligent damping circular ring is formed for the electronic injection fuel pump, therefore, collision cannot be generated by the electronic injection fuel pump during work, further, the service life of the electronic injection fuel pump is prolonged; and the external-hanging-type double-layer damper for the electronic injection fuel pump is convenient to install and is simple to operate.
Description
Technical field
The utility model relates to a kind of vibration damper, particularly a kind of external hanging type electric-spraying fuel pump double-layer shock-absorbing device.
Background technique
The damping modes of at present common external hanging type electric-spraying fuel pump is the mode of single rubber (nitrile butadiene rubber) beam; It is simple in structure, and damping effect is not clear, and automobile in motion; Because pavement roughness; Thump is quite big, and the electric-spraying fuel pump in work is also shaken with it, and this makes commutator and brush in the motor collide each other.Commutator and brush produce very big electrical spark, and shortened the working life of fuel pump greatly.The policy because present domestic automobile is gone to the countryside, the domestic automobile growth rate is very fast, adds that again the rural road is more uneven, and this phenomenon is more obvious.And the maintenance website is less in the rural area, can not get on-call maintenance.
The model utility content
The utility model technical problem to be solved provides a kind of external hanging type electric-spraying fuel pump double-layer shock-absorbing device, and it forms an intelligent damping annulus to electric-spraying fuel pump, and electric-spraying fuel pump at work can not produce collision.
For solveing the technical problem; The utility model provides a kind of external hanging type electric-spraying fuel pump double-layer shock-absorbing device, it is characterized in that, it comprises electric-spraying fuel pump, following movable frame, following retainer ring, mounting plate, is fixed snap ring, damping spring, beam, goes up retainer ring, goes up movable frame; Last retainer ring is symmetrical with following retainer ring; Damping spring is contained in down in the hole that forms between retainer ring and the last retainer ring, and last movable frame is located at a side of retainer ring, and following movable frame and mounting plate lay respectively at down the both sides of retainer ring; Be fixed snap ring and be located on the mounting plate, beam is between electric-spraying fuel pump and following movable frame.
Preferably, the length of said retainer ring down is less than the length of following movable frame, and the length of last retainer ring is less than the length of last movable frame.
The positive progressive effect of the utility model is: the utility model external hanging type electric-spraying fuel pump double-layer shock-absorbing device forms an intelligent damping annulus to electric-spraying fuel pump; Electric-spraying fuel pump at work can not produce collision; Improved the working life of electric-spraying fuel pump; And it is easy for installation, simple to operate.
Description of drawings
Fig. 1 is the structural representation of the utility model external hanging type electric-spraying fuel pump double-layer shock-absorbing device.
Fig. 2 is a structural representation of going up retainer ring and last movable frame in the utility model.
Embodiment
Lift a preferred embodiment below, and combine accompanying drawing to come the clearer the utility model of intactly explaining.
As depicted in figs. 1 and 2; The utility model external hanging type electric-spraying fuel pump double-layer shock-absorbing device comprises electric-spraying fuel pump 1, following movable frame 2, following retainer ring 3, mounting plate 4, is fixed snap ring 5, damping spring 6, beam 7, goes up retainer ring 8, goes up movable frame 9; Last retainer ring 8 and following retainer ring 3 are symmetrical; Damping spring 6 is contained in down in the hole that forms between retainer ring 3 and the last retainer ring 8, and last movable frame 9 is located at a side of retainer ring 8, and following movable frame 2 and mounting plate 4 lay respectively at down the both sides of retainer ring 3; Be fixed snap ring 5 and be located on the mounting plate 4, beam 7 is between electric-spraying fuel pump 1 and following movable frame 2.The length of following retainer ring 3 is less than the length of following movable frame 2, and the length of last retainer ring 8 is less than the length of last movable frame 9.
The utility model external hanging type electric-spraying fuel pump double-layer shock-absorbing device forms an intelligent damping annulus to electric-spraying fuel pump; Played a good damping effect; When automobile in motion, how no matter how road surface out-of-flatness, how automobile shakes; Electric-spraying fuel pump at work can not produce collision yet, and commutator in the motor and brush keep good relationship.The electrical spark that commutator and brush produce significantly reduces, and has improved the working life of electric-spraying fuel pump so greatly, and easy for installation, simple to operate.When the electric-spraying fuel pump burst damages; Only need the car owner to provide electric-spraying fuel pump in advance for oneself; Press the maintenance instruction operation, can ownly directly change electric-spraying fuel pump, need not move car to maintenance station and remove to change electric-spraying fuel pump; Save car owner's great amount of time, also can not delay car owner's important thing.
Though more than described the embodiment of the utility model; But those skilled in the art is to be understood that; These only illustrate, and under the prerequisite of principle that does not deviate from the utility model and essence, can make numerous variations or modification to these mode of executions.Therefore, the protection domain of the utility model is limited appended claims.
Claims (2)
1. external hanging type electric-spraying fuel pump double-layer shock-absorbing device; It is characterized in that; It comprises electric-spraying fuel pump, following movable frame, following retainer ring, mounting plate, is fixed snap ring, damping spring, beam, goes up retainer ring, goes up movable frame, and last retainer ring is symmetrical with following retainer ring, and damping spring is contained in down in the hole that forms between retainer ring and the last retainer ring; Last movable frame is located at a side of retainer ring; Following movable frame and mounting plate lay respectively at down the both sides of retainer ring, are fixed snap ring and are located on the mounting plate, and beam is between electric-spraying fuel pump and following movable frame.
