Description

A kind of electrocar handle connecting structure

Technical field

The utility model relates to transport trolley, particularly a kind of electrocar handle connecting structure.

Background technology

In prior art, if Granted publication number is the disclosed handle connecting structure of utility model patent of CN203450169U, handle is just rotationally connected with corresponding mount pad simply.

Utility model content

The purpose of this utility model is to provide a kind of electrocar handle connecting structure, makes handle can automatically return to more vertical state.

Above-mentioned technical purpose of the present utility model is achieved by the following technical programs: a kind of electrocar handle connecting structure, comprise oil pump body, be rotationally connected with the handle of described oil pump body by axle, this transport trolley handle connecting structure also comprises elastic recovery mechanism, and described elastic recovery mechanism comprises and is placed on described axle and one end is servo-actuated in described handle and the other end can contact at the torsion spring of described oil pump body.

In the time rotating handle, make the torsion spring can be compressed; Thereby in the time of release handle, handle can be replied due to the effect of torsion spring.

As of the present utility model preferably, described handle, at its lower end portion has two and all has the rotor plate that is suitable for the running-on that is socketed described axle; The position that described rotor plate departs from described running-on is provided with the hole that is suitable for the insertion of torsion spring end.

As of the present utility model preferred, described torsion spring has two; Two described torsion springs can contact at the end one connection of described oil pump body.

Above-mentioned setting, makes between two rotor plates stressed more balanced.

As of the present utility model preferred, the free ending tool of described rotor plate is jagged, and described oil pump body is provided with the bumping post falling within described breach; The two ends of described breach are the positive stop end that can contact at described bumping post.

Make on the one hand handle in the time replying position, avoid, because the effect of torsion spring is rocked, on the other hand, avoiding excessively pressing down handle, to protect the unlikely excessive deformation of torsion spring.

As of the present utility model preferred, the both ends of described axle are provided with respectively knock hole; On described oil pump body, have the trepanning that is suitable for being socketed described axle; On the lateral wall of described trepanning, have cotter way; This transport trolley handle connecting structure also comprises the pin that is arranged in described cotter way and is plugged in described knock hole.

Two relative two sides of trepanning are commonly referred to as madial wall, and opposing two side is commonly referred to as lateral wall.

As of the present utility model preferred, with respect to the madial wall of described trepanning, the lateral wall of the close corresponding trepanning of corresponding described rotor plate.

Above-mentioned setting, one side makes more attractive in appearance, also plays on the other hand the effect of protected key and axle.

In sum, the utlity model has following beneficial effect: the utility model is simple in structure, easy to implement; Can make handle automatically reply, improve lever operated convenience.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in further detail.

This specific embodiment is only to explanation of the present utility model; it is not to restriction of the present utility model; those skilled in the art are reading after this specification sheets and can make to the present embodiment the amendment that there is no creative contribution as required, but as long as within the scope of claim of the present utility model, are all subject to the protection of patent law.

Embodiment: as Figure 1-4, a kind of electrocar handle connecting structure, comprises oil pump body 1, the two side of oil pump body 1 has 12, two relative two sides of trepanning 12 of trepanning and is commonly referred to as madial wall, and opposing two side is commonly referred to as lateral wall.

On the lateral wall of trepanning 12, have cotter way 121; In trepanning 12, be socketed with axle 3, the both ends of axle 3 have respectively knock hole 31, and knock hole 31 falls within cotter way 121, is provided with pin 5 in cotter way 121, and pin 5 is plugged in knock hole 31.

The bottom of handle 2 has on 21, two rotor plates 21 of two rotor plates and all has running-on 211, and running-on 211 is socketed on axle 3, and with respect to the madial wall of trepanning 12, and corresponding rotor plate 21 is near the lateral wall of corresponding trepanning 31.

On the lateral wall of trepanning 12, be also provided with bumping post 11, the free ending tool of rotor plate 21 is jagged 212, and oil pump body 1 is provided with the bumping post 11 falling within breach 212; The two ends of breach 212 are the positive stop end 2121 that can contact at bumping post 11.

Be that embodiment also comprises elastic recovery mechanism, elastic recovery mechanism comprises and is placed on axle 3 and one end is servo-actuated in handle 2 and the other end can contact at the torsion spring 41 of oil pump body 1; There is the conflict end 13 that contacts at all the time torsion spring 41 at oil pump body 1.

Torsion spring 41 has two; Two torsion springs 41 can contact at the end one connection of oil pump body 1.
