Cylinder, the other end and screw rod impeller rotating contact；The spring is supported between rear cover and screw rod impeller, and the screw rod pushes
Part is supported between sleeve and spring.
A kind of cylinder buffering connector as described above, one end of the screw rod are equipped with bulb, and the other end is equipped with threaded portion；Institute
It states screw rod impeller and is recessed with cular arc groove, the notch of cular arc groove is greater than the diameter in the bulb of the screw rod, the ball of the screw rod
The diameter in portion is less than the diameter of the through-hole of sleeve, and screw rod rotates in the cular arc groove of screw rod impeller.
A kind of cylinder buffering connector as described above, the periphery wall of the sleeve are equipped with a section, which is convenient for spanner
Screw the sleeve and rear cover.
Compared to the prior art, technical solution provided by the utility model has the following beneficial effects:
First is that in existing screw portion, increase is equipped with impeller, the cooperation of threaded shank and screw rod impeller, can be with
It eliminates between two axis because of error caused by connection, remains the eccentric function of generating when the assembling of existing cylinder connector；
Second is that when cylinder pushes buffering, impeller stress squeezes the work that spring plays buffering spring is added in sleeve inner
With the stroke of spring buffer can adjust increase cushion stroke in 6mm or so according to the actual situation；
Third is that the outer peripheral surface of sleeve and rear cover is equipped with section, in order to screw sleeve and rear cover by spanner；
Fourth is that screw rod, screw rod impeller and spring etc. are built in sleeve, integrally not product is smaller for connector, easy for installation,
The case where interference is not present during assembling board.

Illustrate the utility model cylinder buffering connector, including nut 10, screw rod 20, screw rod impeller now in conjunction with Fig. 1 to Fig. 3
30, spring 40, sleeve 50 and rear cover 60.The screw rod impeller 30 and spring 40 are placed in sleeve 50.The rear cover 60 is spirally connected
In the bottom of sleeve 50, the screw rod 20 runs through the top of the sleeve 50, and one end is pierced by sleeve 50, the other end and screw rod impeller
30 rotating contacts.The spring 40 is supported between rear cover 60 and screw rod impeller 30, and the screw rod impeller 30, which is supported, to be covered
Between cylinder 50 and spring 40.
Specifically, the top of the sleeve 50 is equipped with a through-hole 51, bottom is equipped with internal screw thread, and in the periphery of the sleeve 50
Wall is equipped with a section 52, which screws the sleeve 50 and rear cover 60 convenient for spanner.
One end of the screw rod 20 is equipped with bulb 21, and the other end is equipped with threaded portion 22.
The screw rod impeller 30 is recessed with eccentric grove, which is a cular arc groove 31, the slot of the cular arc groove 31
Inner wall 311 is arc-shaped compatible with the bulb 21 of screw rod 20.The notch 312 of cular arc groove 31 is greater than the ball of the screw rod 20
The diameter in portion 21 is freely rotated so that the bulb 21 of the screw rod 20 packs into the cular arc groove 31 from the side channel mouth 312, and should
The other end of stud 20 is pierced by the through-hole 51 of sleeve 50, so that the threaded portion 22 of stud 20 is placed in outside sleeve 50, and passes through nut
10 with other component bolt, convenient for postorder assemble.
The diameter in the bulb 21 of the screw rod 20 is less than the diameter of the through-hole 51 of sleeve 50, and screw rod 20 is in screw rod impeller 30
Cular arc groove 31 in can rotate, but screw rod 20 does not pull out not Chu Lai the sleeve 50 upwards.Therefore, if cylinder and tooling are controlled
When having decentraction, bias, even if the screw rod 20 of the utility model cylinder buffering connector biases certain angle, it will not influence to make
With the eccentricity issues that solution cylinder connector generates when assembling.
The male end 61 that the rear cover 60 matches with the internal screw thread of one and sleeve 50, to be screwed on sleeve 50.
The rear cover 60 is additionally provided with the internal thread hole 62 to match with the catch bar of cylinder, with complete the utility model cylinder buffering connector with
The connection of cylinder.When the catch bar of cylinder is released, driven member meets obstructions, and screw rod 20 squeezes spring along impeller down
40, it is formed the effect of buffering.
The optimized buffer stroke of the present embodiment spring 40 is located at 6mm or so.Required cushion stroke and cushion effect it is big
It is small, it can rotate and exit rear cover 60, replace screw pitch/line footpath appropriate/interior diameter spring or cut short the length of spring to realize
The cushion stroke needed.
The preferred embodiment of the utility model has shown and described in above description, as previously described, it should be understood that this is practical new
Type is not limited to forms disclosed herein, and should not be regarded as an exclusion of other examples, and can be used for various other groups
