Abstract
The utility model discloses a push rod falling-prevention mechanism. The push rod falling-prevention mechanism comprises a fixing pin, a handle, a pin bush, an elastic clamping ring and a positioning pin, wherein the fixing pin is provided with a tapered groove which is big in the front and small in the back, the pin bush is sleeved outside the fixing pin, one end of the fixing pin is connected with the handle, the pin bush is provided with a positioning pin hole which penetrates the pin bush in the radial direction, the positioning pin is arranged inside the positioning pin hole in a penetrating mode, the inner end of the positioning pin abuts against the outer surface of the fixing pin, and the elastic clamping ring which is capable of limiting the positioning pin inside the positioning pin hole is sleeved outside the pin bush. In use, the fixing pin adopted by the push rod falling-prevention mechanism moves forwards and can reliably position parts needing positioning. When the fixing pin moves backwards, the positioning pin can be well prevented from being drawn out from the pin bush. The push rod falling-prevention mechanism has the advantages of being simple in structure, safe, reliable, and easy to achieve.
Description
Technical field
The utility model belongs to the cubing technical field, especially relates to a kind of push rod escapement.
Background technique
Now each large automobile component product cubing manufacturer project organization variation, often that the cubing structural design is huger for satisfying measurement effect, cause raw-material waste, and multiple different structure occurs in the cover cubing, so that processing cost increases suddenly, use also comparatively loaded down with trivial details, simultaneously, existing cubing positioning means relates to a kind of mechanism of location, and the effect of this mechanism is the location of realizing cubing, and change into the positioning means complex structure, manufacture cost is high.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of novelty simple in structure, the push rod escapement of good reliability.
The technical solution of the utility model is as follows: a kind of push rod escapement, its main points are: comprise fixing pin, handgrip, guide, snap ring and locating stud, shallow cone tank after wherein dark before fixing pin is provided with, the described guide of overcoat on described fixing pin, described fixing pin one end is threaded with described handgrip, have the positioning pin hole that radially runs through this guide at described guide and in described positioning pin hole, be equipped with described locating stud, this locating stud the inner is against on the described fixing pin outer surface, at described guide overcoat the snap ring that described locating stud can be limited in the described positioning pin hole is arranged.In the above structure, the principle of drag link mechanism is such: when handgrip is advanced, under the effect of handgrip, fixing pin moves forward, at this moment, locating stud is against on the surface of described fixing pin, when handgrip is pulled out, under the effect of handgrip, fixing pin is mobile backward, at this moment, because the existence of cone tank, under the effect of snap ring, locating stud is against on the surface of described cone tank, because cone tank is front dark rear shallow, under the effect of cone tank, fixing pin has been limited mobile backward, thereby has prevented that fixing pin is drawn out.
Have circumferential groove at described guide outer surface, described positioning pin hole is arranged on described in this circumferential groove, and described circumferential groove is interior to be limited in described locating stud in the described positioning pin hole thereby described snap ring is stuck in.Adopt above structure, circumferential groove can realize the reliable installation of snap ring, prevents that snap ring is mobile at guide.
Beneficial effect: employing of the present utility model, during use, fixing pin moves forward and can be reliably the parts of needs location be positioned, and when fixing pin moves backward, can be good at preventing that locating stud from pulling out in guide; The utlity model has simple in structure, safe and reliable, be easy to the characteristics such as realization.
Description of drawings
Fig. 1 is structure intention of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
See also Fig. 1: a kind of push rod escapement, comprise fixing pin 1, handgrip 2, guide 3, snap ring 4 and locating stud 5, shallow cone tank 1a after wherein dark before fixing pin 1 is provided with, the described guide 3 of overcoat on described fixing pin 1, described fixing pin 1 one ends are threaded with described handgrip 2, have the positioning pin hole 3b that radially runs through this guide 3 at described guide 3, in described positioning pin hole 3b, be equipped with described locating stud 5, these locating stud 5 the inners are against on described fixing pin 1 outer surface, at described guide 3 overcoats the snap ring 4 that described locating stud 5 can be limited in the described positioning pin hole 3b are arranged.
In Fig. 1, it can also be seen that: have circumferential groove 3a at described guide 3 outer surfaces, described positioning pin hole 3b is arranged on described in this circumferential groove 3a, and described circumferential groove 3a is interior to be limited in described locating stud 5 in the described positioning pin hole 3b thereby described snap ring 4 is stuck in.
The above only is preferred embodiment of the present utility model; not take the utility model as restriction; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
