Description
Technical field
The utility model relates to a kind of bolts.
Background technique
The Chinese utility model patent of Patent No. 201720222750.2 discloses a kind of pressing push type world bolt.
In use, finger pins the pressing key of locating piece, pressing spring under locating piece rotates positioning key to external splint lid direction.If needing
Pin is moved up, then finger resists the step above pressing key, and pushes up, due to the inclined surface court of the positioning tooth
Under, therefore push up the inclined surface upward sliding that step can make positioning key along positioning tooth.Therefore the inclined surface of the positioning tooth
The power that finger applies to pressing key when positioning key pushes up can be reduced to a certain extent.And if pin need to be moved down,
Same finger pins the pressing key of locating piece, rotates positioning key to external splint lid direction.And finger push presses below key
Step, pin can be realized and move down, only need to be slightly towards pressing since there are certain gravity for pin and Mobile base
Force, can be realized pin and moves down below key；The process of above-mentioned this kind of structure opening and closing bolt rod requires manually
Simultaneously slidable adjustment is pressed, it is inconvenient for operation.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of easy to operate bolts.
Technical solution adopted by the utility model to solve the above technical problems is as follows: a kind of bolt, including mounting base, it is described
The rear end of mounting base be provided with the bolt rod that cooperation is slided up and down with it, limit plectrum, institute are provided in the mounting base
The first end for the limit plectrum stated is plugged in the mounting base, offers limit in the second end of the limit plectrum
Hole, the bolt rod are threaded through in the limit hole and are engaged by clamping with its inner wall, the second end of the limit plectrum
Top is equipped with first back-moving spring between the mounting base, is provided with gag lever post on the side wall of the bolt rod, described
The rear end of mounting base is provided with limited block, and top is equipped with second back-moving spring between the gag lever post and the limited block.
The further preferred scheme of the utility model are as follows: when not stirring the limit plectrum, the limit plectrum
It is inclined to set, the side inner wall of the limit hole is in contact with the bolt rod；When stirring the limit plectrum,
The limit plectrum disengages between the inner wall of the limit hole and the bolt rod in being horizontally disposed with.
The further preferred scheme of the utility model are as follows: the rear end of the mounting base offers and the gag lever post phase
The sliding slot of adaptation, the gag lever post are located in the sliding slot and slide up and down cooperation with it.
The further preferred scheme of the utility model are as follows: the internal diameter of the limit hole is greater than the outer of the bolt rod
Diameter.
The further preferred scheme of the utility model are as follows: slot, the limit plectrum are offered in the mounting base
First end be plugged in the slot, the thickness of the limit plectrum is less than the width of the slot.
When compared with prior art, the utility model has the advantage of locking bolt is needed, it need to only dial up limit and dial
Piece, bolt rod can rebound automatically, easy to operate, time saving and energy saving.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the cross-sectional view of bolt in the on-state in the utility model；
Fig. 3 is cross-sectional view of the utility model when stirring limit plectrum.
Specific embodiment
The utility model is described in further detail below in conjunction with figure embodiment.
As shown, a kind of bolt, including mounting base 1, the rear end of mounting base 1, which is provided with, slides up and down inserting for cooperation with it
Pin rod 2 is provided with limit plectrum 3 in mounting base 1, and the first end of limit plectrum 3 is plugged in mounting base 1, and the of limit plectrum 3
Offering limit hole 31 on two ends, bolt rod 2 is threaded through in limit hole 31 and is engaged by clamping with its inner wall, and the of limit plectrum 3
Top is equipped with first back-moving spring 4 between two ends and mounting base 1, is provided with gag lever post 21 on the side wall of bolt rod 2, mounting base 1
Rear end is provided with limited block 11, and top is equipped with second back-moving spring 5 between gag lever post 21 and limited block 11, when not stirring limit plectrum
When 3, limit plectrum 3 is inclined to set, and the side inner wall of limit hole 31 is in contact with bolt rod 2；When stirring limit plectrum 3,
Plectrum 3 is limited in horizontally disposed, is disengaged between the inner wall and bolt rod 2 of limit hole 31, the rear end of mounting base 1 offer with
The compatible sliding slot 12 of gag lever post 21, gag lever post 21 are located in sliding slot 12 and slide up and down cooperation, the internal diameter of limit hole 31 with it
Greater than the outer diameter of bolt rod 2, slot 13 is offered in mounting base 1, the first end of limit plectrum 3 is plugged in slot 13, limits
The thickness of plectrum 3 is less than the width of slot 13.
Working principle: when bolt rod is in initial lock state, in acting on for first back-moving spring, plectrum quilt is limited
It withstanding and is inclined to set, the inner wall of limit hole is contacted with bolt rod, and when need to open bolt, bolt is moved downward to extreme lower position,
Under the action of first back-moving spring, limit plectrum holding is obliquely installed, and is in contact between the inner wall and bolt rod of limit hole, and two
Frictional force is generated between person, be sprung back bolt rod will not, is maintained at opening state, when needing dead bolt, it is only necessary to
On stir the first end of limit plectrum, limit plectrum is in horizontally disposed, and the inner wall of limit hole is not contacted with bolt rod at this time, the two
Between frictional force disappear, under the action of second back-moving spring, bolt rod automatic rebounding to original state.
A kind of bolt provided by the utility model is described in detail above, specific case pair used herein
The principles of the present invention and embodiment are expounded, and the above embodiments are only used to help understand, and this is practical new
Type and core concept.It should be pointed out that for those skilled in the art, not departing from the utility model principle
Under the premise of, several improvements and modifications can be made to this utility model, these improvement and modification also fall into the utility model
In scope of protection of the claims.
