Abstract
The utility model relates to a cylinder connector. The cylinder connector comprises an upper joint and a lower joint, wherein the upper joint is connected with a movable rod of a cylinder, and the lower joint is connected with a use device; a cylindrical portion and a circular boss are sequentially formed at the lower end of the upper joint from top to bottom; a narrow groove and a wide groove are sequentially formed in the upper end face of the lower joint from top to bottom; the cylindrical portion of the upper joint is arranged in the narrow groove; the circular boss of the upper joint is arranged in the wide groove; the diameter of the cylindrical portion is smaller than the width of the narrow groove; and the diameter of the circular boss is smaller than the width of the wide groove and is greater than the width of the narrow groove. The cylinder connector is applicable to special occasions and can automatically compensate the coaxiality deviation between the cylinder and the use device, and the compensation range is relatively large.
Description
Technical field
The utility model relates to a kind of for the motion bar that connects cylinder and the cylinder joint that uses device.
Background technique
The cylinder joint is for the motion bar that connects cylinder and the critical component that uses device.The structure of present employed cylinder joint comprises a joint shaft bearing 1 that is connected with the cylinder motion bar and one and the breeches joint 2 that uses device to be connected as shown in Figure 3, is connected by a bearing pin 3 between joint shaft bearing 1 and the breeches joint 2.During use, compensate cylinder and use coaxiality deviation between the device by joint shaft bearing 1, prevent that cylinder is stuck.At some special occasions (as high dust, perishable), traditional joint shaft bearing 1 can't permanently effectively use, and need process with some special materials, has so just increased difficulty of processing and cost.And present employed cylinder joint can only compensate at illustrated fore-and-aft direction, and compensation range is limited on left and right directions, is not suitable for the bigger occasion of coaxiality deviation and uses.
The model utility content
Technical problem to be solved in the utility model is: provides a kind of and can be applicable to special occasions, and the bigger cylinder joint of compensation range.
For addressing the above problem, the technical solution adopted in the utility model is: the cylinder joint, comprise a upper connection that is connected with the cylinder motion bar and a lower contact that is connected with the use device, the lower end of described upper connection is disposed with cylinder part and round boss from top to bottom, offer narrow groove and sipes in the upper-end surface of described lower contact from top to bottom successively, the cylinder part of upper connection is arranged in the narrow groove, the round boss of upper connection is arranged in the sipes, the diameter of described cylinder part is less than the width of narrow groove, and the diameter of described round boss is less than the width of sipes and greater than the width of narrow groove.
Same axis setting between described cylinder part and the round boss.
Same axis setting between described narrow groove and the sipes.
Be provided with the last interior threaded hole that matches with the cylinder motion bar in the upper-end surface of described upper connection.
Be provided with in the lower end surface of described lower contact and the following interior threaded hole that uses device to match.
The beneficial effects of the utility model are: above-mentioned cylinder joint, it is simple in structure, easy for installation, requirement on machining accuracy is low, and it is with low cost, when special occasions uses, even if dust etc. are absorbed in the gap between upper connection and the lower contact, can not produce great influence to this cylinder joint yet, even if this cylinder joint is subjected to slight corrosion, can not use the continuation of this cylinder yet and exert an influence, in addition, between the upper connection and lower contact of this cylinder, can relatively move at left and right directions or fore-and-aft direction, during work, can compensate the coaxiality deviation between cylinder and the use device automatically, and compensation range is bigger.

Embodiment
Below by specific embodiment cylinder joint described in the utility model is described in further detail.
As Fig. 1, shown in Figure 2, the cylinder joint, comprise a upper connection 1 that is connected with the cylinder motion bar and a lower contact 2 that is connected with the use device, be provided with the last interior threaded hole 3 that matches with the cylinder motion bar in the upper-end surface of described upper connection 1, the lower end of upper connection 1 is disposed with cylinder part 4 and round boss 5 from top to bottom, same axis setting between cylinder part 4 and the round boss 5, be provided with in the lower end surface of described lower contact 2 and the following interior threaded hole 6 that uses device to match, offer narrow groove 7 and sipes 8 in the upper-end surface of lower contact 2 from top to bottom successively, same axis setting between narrow groove 7 and the sipes 8, the cylinder part 4 of upper connection 1 is arranged in the narrow groove 7, the round boss 5 of upper connection 1 is arranged in the sipes 8, the diameter of described cylinder part 4 is less than the width of narrow groove 7, and the diameter of described round boss 5 is less than the width of sipes 8 and greater than the width of narrow groove 7.
Above-mentioned cylinder joint, it is simple in structure, easy for installation, requirement on machining accuracy is low, and it is with low cost, only need round boss 5 with upper connection 1 snap in the sipes 8 of lower contact 2 during installation and just finish installation, when special occasions uses, even if dust etc. are absorbed in the gap between upper connection 1 and the lower contact 2, can not produce great influence to this cylinder joint yet, even if this cylinder joint is subjected to slight corrosion, can not use the continuation of this cylinder yet and exert an influence, in addition, between the upper connection 1 and lower contact 2 of this cylinder, owing to have the gap between the cylinder part 4 of upper connection 1 and the narrow groove 7 of lower contact 2, there is the gap between the round boss 5 of upper connection 1 and the sipes 8 of lower contact 2, so can relatively move at left and right directions or fore-and-aft direction between upper connection 1 and the lower contact 2, during work, can compensate the coaxiality deviation between cylinder and the use device automatically, and compensation range is bigger.
The above embodiments are principle and the effect thereof of illustrative the invention only, and the embodiment of part utilization, but not is used for restriction the utility model; Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model creation design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
