Abstract
The utility model relates to a prevent to transport automatic bolt device of opening of frock clamp plate, including fixing the sleeve in the transportation frock, insert the round pin axle that the cover has the spring in the sleeve, sell the epaxial rand that is fixed with, the both ends of spring support rand and telescopic tail end inner wall respectively, and the tail end of round pin axle is connected with the handle through the nut, and when the spring was in release condition, the sleeve front end stretched out in round pin spindle nose portion for it prevents its automatic performing fighting to block the clamp plate, when the spring is in compression state, in the round pin spindle nose portion retraction sleeve, but the clamp plate free rotation. During the use, the pulling handle owing to the threaded connection of self -locking nut with the round pin axle, makes and sells the motion of axial left side. At this moment, spring compressed between sleeve and round pin axle. Loosen the handle, axial right side top will be sold to spring release elasticity to reach automatic re -setting's function.
Description
Technical field
This utility model relates to a kind of bolt device, a kind of bolt device preventing transport frock pressing plate from automatically opening up.
Background technology
In recent years along with the development of track traffic, the production of rail vehicle develops to modularity direction, substantially increases production efficiency and the quality of production.Modularized production it is also proposed new problem for the transport of each parts, and Traditional Transportation frock is simple and crude due to structure, it is impossible to adapt to the needs of high-efficiency environment friendly instantly.Then applicant have developed some and arranges reusable transport frock, for haulage vehicle parts, such as framed side wallboard, skirtboard etc..Due to its compact conformation, security performance is good, again can in limited space maximum loading vehicles parts, compare Traditional Transportation frock and there is relatively much progress.
It is provided with turnover pressing plate inside frock, and pressing plate is opened and i.e. be can be taken off parts, is easily subject to vibrations at transportation center platen and automatically opens up, once automatically open up, the parts within frock may be made to lose original support and be damaged.
Summary of the invention
Technical problem to be solved in the utility model is, overcomes the disadvantages mentioned above of prior art, it is provided that a kind of bolt device preventing transport frock pressing plate from automatically opening up.
In order to solve above technical problem, what this utility model provided prevents the bolt device that transport frock pressing plate automatically opens up, it is characterized in that: include the sleeve being fixed in transport frock, described sleeve is inserted into being cased with the bearing pin of spring, it is fixed with collar on described bearing pin, the two ends of spring are respectively held against the tail end inwall of collar and sleeve, the tail end of described bearing pin is connected by nut handle, when spring is in release conditions, bearing pin head stretches out barrel forward end, is used for blocking pressing plate and prevents it from automatically opening up；When spring is in compressive state, in bearing pin head retraction sleeve, pressing plate is free to rotate.
This utility model also has a following improvement:
1, described nut is self-locking nut.
2, during described spring release conditions, the front end of handle props up the rear end face of sleeve.
3, described collar bulge loop replaces.
During use, pull handle, due to threadeding of self-locking nut and bearing pin, make bearing pin move to the left.Now, the spring between sleeve and bearing pin is compressed.In bearing pin head retraction sleeve, pressing plate is free to rotate.Unclamping handle, spring release elastic force, pushed up to the right by bearing pin, thus reach automatically reset function, when spring is in release conditions, bearing pin head stretches out barrel forward end, is used for blocking pressing plate and prevents it from automatically performing fighting.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings this utility model is further described.
Fig. 1 is the bolt device structural representation that this utility model prevents transport frock pressing plate from automatically opening up.
In figure schematically as follows:
1 self-locking nut；2 handles；3 sleeves；4 bearing pins；5 springs；6-collar.
Detailed description of the invention
As shown in Figure 1, prevent the bolt device that transport frock pressing plate automatically opens up, including the sleeve 3 being fixed in transport frock, sleeve 3 is inserted into being cased with the bearing pin 4 of spring 5, and bearing pin 4 is fixed with collar 6(collar 6 can be replaced with bulge loop), the two ends of spring 5 are respectively held against the tail end inwall of collar 6 and sleeve 3, the tail end of bearing pin 4 is connected by self-locking nut 1 handle 2, when spring 5 is in release conditions, bearing pin 4 head stretches out sleeve 3 front end, is used for blocking pressing plate and prevents it from automatically opening up；When spring 5 is in compressive state, in bearing pin 4 head retraction sleeve 3, pressing plate is free to rotate.When spring 5 release conditions, the front end of handle 2 props up the rear end face of sleeve 3.
When pulling handle 2, due to threadeding of self-locking nut 1 and bearing pin 4, bearing pin 4 is made to move to the left.Now, the spring 5 between sleeve 3 and bearing pin 4 is compressed.Unclamping handle 2, spring 5 loses power to the left, discharges elastic force, is pushed up to the right by bearing pin 4, thus reach automatically reset function.
In addition to the implementation, this utility model can also have other embodiments.The technical scheme that all employing equivalents or equivalent transformation are formed, all falls within the protection domain of this utility model requirement.
Claims (4)
