Abstract
The utility model relates to a kind of bolt devices, including pulling pin bar, one end of pulling pin bar is equipped with pulling pin knob, the other end of pulling pin bar passes through pressing plate and is cased with the first compressed spring, and pulling pin bar is equipped with groove, and pressing plate is equipped with the protrusion with matching grooves, the other end of pulling pin bar withstands one end of pulling pin connecting rod, it is installed with bolt rod in pulling pin connecting rod, the second compressed spring, the other end and rotation axis connection of pulling pin connecting rod are cased on bolt rod.When protrusion snaps into groove, bolt rod can stretch, and after bolt rod is fully retracted, rotate pulling pin bar, protrusion and the position of groove mismatch, and bolt rod is no longer flexible, makes to adjust more convenient.
Description
Technical field
The utility model relates to a kind of bolt devices.
Background technique
Currently, a kind of is exactly plug-in there are two types of existing bolts, need to extract bolt rod completely, being then adjusted to needs
It is inserted into bolt rod behind the position wanted to be fixed, bolt rod needs complete alignment pins hole that could be inserted into, inconvenient to use；Such as
Fruit needs bolt to be constantly in disengaged condition, needs to extract bolt, is easy to lose.Another kind is the elastic force needed against spring
Bolt pulls out bolt rod, is then adjusted to the position defensive position release nearby of needs, slightly adjustment snibbing position, bolt rod meeting
It is automatically inserted into pin hole；The shortcomings that this bolt is bolt cannot to be made to be constantly in disengaged condition.
Utility model content
The purpose of this utility model is to overcome above deficiency, provide that a kind of structure is simple, bolt easy to use
Device.
The purpose of this utility model is achieved through the following technical solutions: a kind of bolt device, including pulling pin bar, pulling pin bar
One end be equipped with pulling pin knob, the other end of pulling pin bar passes through pressing plate and is cased with the first compressed spring, and pulling pin bar is equipped with groove, pressure
Plate is equipped with the protrusion with matching grooves, and the other end of pulling pin bar withstands one end of pulling pin connecting rod, is installed with bolt in pulling pin connecting rod
Bar is cased with the second compressed spring, the other end and rotation axis connection of pulling pin connecting rod on bolt rod.
Compared with the prior art, the utility model has the following advantages:
When protrusion snaps into groove, the position defensive position release nearby that pulling pin bar is then adjusted to needs is pressed, is slightly adjusted
Whole snibbing position, bolt rod are automatically inserted into pin hole.It is constantly in disengaged condition if necessary to bolt, only needs bolt rod complete
After retraction, pulling pin bar is rotated, protrusion and the position of groove mismatch, and bolt rod is no longer flexible；When needing to release disengaged condition, only
Pulling pin bar need to be rotated, matches protrusion again with the position of groove, bolt rod automatic spring.
Detailed description of the invention:
Fig. 1 is the state diagram of bolt rod pop-up；
Fig. 2 is latch retract and reducible state diagram；
Fig. 3 is the not reducible state diagram of latch retract；
Fig. 4 is the part-structure enlarged drawing of pulling pin bar and pulling pin knob；
Figure label: 1- pulling pin bar, 2- pulling pin knob, 3- pressing plate, the first compressed spring of 4-, 5- groove, 6- protrusion, 7- are drawn
Sell connecting rod, 8- bolt rod, the second compressed spring of 9-, 10- rotary shaft.
Specific embodiment:
It, below will be to the utility model to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Technical solution in embodiment is clearly and completely described, it is clear that described embodiment is that the utility model a part is real
Example is applied, instead of all the embodiments.The elements and features described in a kind of embodiment of the utility model can be with one
Elements and features shown in a or more other embodiment combine.It should be noted that for purposes of clarity, in explanation
The expression and description of component unrelated with the utility model, known to persons of ordinary skill in the art and processing is omitted.It is based on
The embodiments of the present invention, those of ordinary skill in the art institute obtained under the premise of not making the creative labor
There are other embodiments, fall within the protection scope of the utility model.
One end of a kind of bolt device, including pulling pin bar 1, pulling pin bar 1 is equipped with pulling pin knob 2, and the other end of pulling pin bar 1 is worn
It crosses pressing plate 3 and is cased with the first compressed spring 4, as shown in figure 4, pulling pin bar 1 is equipped with groove 5, pressing plate 3 is equipped with and matches with groove 5
Protrusion 6, the other end of pulling pin bar 1 withstands one end of pulling pin connecting rod 7, bolt rod 8 is installed in pulling pin connecting rod 7, is covered on bolt rod 8
There is the second compressed spring 9, the other end of pulling pin connecting rod 7 is connect with rotary shaft 10.
As shown in Figure 1, bolt rod 8 is in the state of pop-up, two compressed springs 4,9 are all in relaxation state；Such as Fig. 2 institute
Show, pulling pin bar 1 ejects, and pulling pin connecting rod 7 drives bolt rod 8 to retract, and two compressed springs 4,9 exist all in impaction state, protrusion 6
In groove 5, bolt rod 8 can reset at any time；As shown in Figures 3 and 4, protrusion 6 is not stuck in groove 5, and pulling pin bar 1 cannot contract
It returns, i.e., pulling pin connecting rod 7 is immovable, and bolt rod 8 can not reset.
When protrusion snaps into groove, the position defensive position release nearby that pulling pin bar is then adjusted to needs is pressed, is slightly adjusted
Whole snibbing position, bolt rod are automatically inserted into pin hole.It is constantly in disengaged condition if necessary to bolt, only needs bolt rod complete
After retraction, pulling pin bar is rotated, protrusion and the position of groove mismatch, and bolt rod is no longer flexible；When needing to release disengaged condition, only
Pulling pin bar need to be rotated, matches protrusion again with the position of groove, bolt rod automatic spring.
Finally, it should be noted that although the utility model and its advantage have been described in detail above it should be appreciated that
Various change can be carried out without departing from the spirit and scope of the utility model being defined by the claims appended hereto
Become, substitute and converts.Moreover, the scope of the utility model is not limited only to process, equipment described in specification, means, method
With the specific embodiment of step.One of ordinary skilled in the art is from the disclosure of the utility model it will be readily understood that root
It can be used according to the utility model and execute the function essentially identical to corresponding embodiment described herein or obtain basic with it
Identical result, existing and to be developed in the future process, equipment, means, method or step.Therefore, appended right
It is required that be intended to includes such process, equipment, means, method or step in the range of them.
