Abstract
The utility model discloses a stop mechanism which comprises a stop pin, a straight pin and a stop screw, wherein the stop pin comprises a pin head and a pin rod assembly; the pin rod assembly comprises a first pin rod, a second pin rod and a transition body; the first pin rod is connected with the pin head; the transition body is of a pyramid type; one end with big section of the transition body is connected with the second pin rod, and one end with small section of the transition body is connected with the first pin rod; and the end of the straight pin is matched with the transition body. Because when the stop pin bears a larger radial force, the straight pin applies a force opposite to the radial force in the direction to the stop pin for avoiding the stop pin from dropping, the stop effect is better; and in addition, the surface in which the straight pin is in contact with the transition body is an inclined surface, the transverse force borne by the stop pin can be divided into different forces in two directions, so that the surface of the stop pin is avoided being stressed to cause deformation, therefore, the stop mechanism has the advantages of better stop effect and easy disassembly.
Description
Technical field
The utility model has related to a kind of stop mechanism.
Background technique
In the market, usually can run into that a plurality of workpiece are taken mutually and come spacing situation by stop pin; For example, the folding street corner of folding bicycle, when two connector for joints were involutory, two links respectively protrude an engaging lug to be taken mutually, inserted a stop pin and ran through two engaging lugs, misplace to limit both to be moved, i.e. fastening this folding joint.
At present, with reference to figure 1, existing stop mechanism mainly comprises stop pin and stop screw 3, and wherein, stop pin comprises plunger 1 and pin rod 2; Plunger 1 is identical with the diameter of pin rod 2; Plunger 1 is complementary with stop screw 3.Existing stop mechanism in use, because stop screw 3 can only be to the stop pin power radially of exerting pressure, and the surface of contact smoother of stop pin and workpiece, when stressed when excessive in vertical direction, stop pin can slide, thereby does not reach the effect of stop; In addition, when stop screw is subject to laterally larger pressure, meeting so that the stop pin surface be out of shape because of pressurized, thereby cause the situation that is difficult to dismantle.
The model utility content
For solving the problems of the technologies described above, the utility model proposes better, the easily detachable stop mechanism of a kind of stopping effect.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of stop mechanism comprises stop pin, straight pin, and stop screw; Stop pin comprises plunger and pin rod group; Stop screw and plunger are complementary, and the pin rod group comprises the first pin rod, the second pin rod, and are located at the transition body between the first pin rod and the second pin rod; The first pin rod is connected with plunger; Transition body is cone type; The large end in transition body cross section is connected with the second pin rod, and the little end in its cross section is connected with the first pin rod; Termination and the transition body of straight pin are complementary.
Preferably, the diameter of plunger is greater than the diameter of the first pin rod and the second pin rod.
Preferably, the diameter of the first pin rod is identical with the diameter of the second pin rod.
By technique scheme, a kind of stop mechanism provided by the utility model, when stop pin was fixed two workpiece, after straight pin passes hole in the workpiece, matched with the transition body of stop pin in its termination; Because when stop pin is subject to larger warp-wise power, straight pin can be to exert pressure power with the opposite direction of warp-wise power of stop pin, to avoid stop pin to come off, thereby so that stopping effect is better, in addition, because the face that straight pin contacts with transition body is the inclined-plane, can be so that the transverse force that stop pin is subject to be divided into the power of different both directions, to avoid stop pin surface compressive deformation, therefore, this stop mechanism has the good and easily detachable advantage of stopping effect.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the disclosed a kind of stop mechanism of prior art;
Plan view when Fig. 2 is the disclosed a kind of stop pin of the utility model embodiment and stop screw assembling;
Fig. 3 is the plan view of the disclosed a kind of straight pin of the utility model embodiment.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technological scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
Referring to figs. 2 and 3, the utility model provides a kind of stop mechanism, comprises stop pin, straight pin 31, and stop screw 23, and stop pin comprises plunger 21 and pin rod group; Stop screw 23 is complementary with plunger 21, and the pin rod group comprises the first pin rod 221, the second pin rod 223, and is located at the transition body 222 between the first pin rod 221 and the second pin rod 223; The first pin rod 221 is connected with plunger 21; Transition body 222 is cone type; The large end in transition body 222 cross sections is connected with the second pin rod 223, and the little end in its cross section is connected with the first pin rod 221; Straight pin 31 terminations and transition body 222 are complementary.During use, stop pin matches with two workpiece, and stop screw 23 is installed between two workpiece, and after straight pin 31 passes hole in the workpiece, match with the transition body 222 of stop pin in its termination.
In addition, the diameter of plunger 21 is greater than the diameter of the first pin rod 221 and the second pin rod 223; The diameter of the first pin rod 221 is identical with the diameter of the second pin rod 223, is convenient to processing and assembling stop pin.
Can find out from technique scheme, a kind of stop mechanism provided by the utility model, stop pin matches with two workpiece, and after straight pin 31 passes hole in the workpiece, match with the transition body 222 of stop pin in its termination; Because when stop pin is subject to larger warp-wise power, straight pin 31 can be to exert pressure power with the opposite direction of warp-wise power of stop pin, to avoid stop pin to come off, thereby so that stopping effect is better, in addition, because the face that straight pin 31 contacts with transition body 222 is the inclined-plane, can be so that the transverse force that stop pin is subject to be divided into the power of different both directions, to avoid stop pin surface compressive deformation, therefore, this stop mechanism has the good and easily detachable advantage of stopping effect.
To the above-mentioned explanation of the disclosed embodiments, make related domain professional and technical personnel can realize or use the utility model.Multiple modification to these embodiments will be apparent concerning those skilled in the art, and General Principle as defined herein can be in the situation that do not break away from spirit or scope of the present utility model, in other embodiments realization.Therefore, the utility model will can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
