Description
Technical field
The present invention relates to locking device technical field, more particularly to a kind of collapsible armed lever locking mechanism.
Background technology
Folding stand is widely used in every field, and general structure is the function that two bars or multiple bars can realize folding,
Each field use is different, and the mode that traditional folding stand is fixed after deployment is varied, has bolt to fix support also
It is further added by a support bar to be supported, these modes can all cause folding stand volume to become big, and use is constant.
The content of the invention
It is an object of the invention to overcome the shortcomings of above-mentioned technology, and provide a kind of collapsible armed lever locking mechanism.
The present invention to achieve the above object, using following technical scheme：
A kind of collapsible armed lever locking mechanism, it is characterised in that：Including main body and armed lever, set in the side wall of the main body
There is a link slot, the first positioning hole, the second positioning hole and axis hole, the arm are respectively equipped with two side walls of link slot
The front end of bar is provided with a hinge being connected with the axis hole, and the upper front end of the armed lever is provided with stopper slot, the stopper slot
Two pieces of latch segments are inside installed, spring is provided between two pieces of latch segments, two pieces of latch segments is close to the side wall of stopper slot, two pieces of locks
A montant is fixed on the top of tight block respectively, and an alignment pin is fixed on the top of montant, and alignment pin is stretched from the front end side of armed lever
Go out and coordinated with first positioning hole, the second positioning hole.
Preferably, the front end of the armed lever is provided with engaging lug, and the hinge is arranged on the engaging lug, the alignment pin
Stretched out from the side of the engaging lug.
Preferably, it is respectively equipped with two pieces of latch segments and clamps hand groove.
The beneficial effects of the invention are as follows:Relative to prior art, the present apparatus is simple and compact for structure, and armed lever can surround main body
Rotated, two positioning holes are set in main body, one is the positioning hole under armed lever deployed condition, and another is armed lever closed form
Positioning hole under state, two latch segments are pinched by hand, latch segment overcomes the elastic force of spring to be close to each other, and alignment pin is recovered to arm
The inside of bar, armed lever can be rotated, after armed lever turns to certain position, unclamp latch segment, alignment pin enters corresponding positioning
Locked in hole, prevent armed lever to be rotated further, present apparatus latch segment is hidden into armed lever, more attractive in appearance.

Fig. 2 is the structural representation under armed lever deployed condition in the present invention；
Fig. 3 is the structural representation of main body in the present invention；
Fig. 4 is the structural representation under two pieces of latch segment deployed conditions in the present invention；
Fig. 5 is the structural representation under two pieces of latch segment closure states in the present invention；
Fig. 6 is the structural representation that two pieces of latch segments coordinate with armed lever in the present invention.
Embodiment
Below in conjunction with the accompanying drawings and preferred embodiment describes the embodiment of the present invention in detail.As shown in figures 1 to 6, it is a kind of
Collapsible armed lever locking mechanism, including main body 1 and armed lever 2；
The side wall of the main body is provided with a link slot 3, and link slot is the structure of half opening, is mainly used in entering with armed lever
Row connection.
The first positioning hole 4, the second positioning hole 5 and axis hole 6, the first positioning are respectively equipped with two side walls of link slot
Hole and the second positioning hole all play a part of with positioning finger setting, it can also be one that can be two, and the present invention is in order to realize
Expansion and two positioning holes of positioning thus setting of closure both direction.
The front end of the armed lever is provided with a hinge 7 being connected with the axis hole, may be rotated by hinge armed lever.
The upper front end of the armed lever is provided with stopper slot 8, and two pieces of latch segments 9, two pieces of lockings are provided with the stopper slot
Spring 10 is provided between block, two pieces of latch segments is close to the side wall of stopper slot, the top of two pieces of latch segments is fixed one and erected respectively
An alignment pin 12 is fixed on bar 11, the top of montant, and alignment pin stretches out and first positioning hole, the from the front end side of armed lever
Two positioning holes are coordinated.When armed lever deploys, alignment pin is inserted into the first positioning hole and positioned, when armed lever closes,
Alignment pin is inserted into the second positioning hole and positioned.In the present invention, the front end of the armed lever is provided with engaging lug 13, the hinge
Axle is arranged on the engaging lug, and the alignment pin stretches out from the side of the engaging lug.
Tight latch segment is held by hand for the ease of user, is respectively equipped with two pieces of latch segments and clamps hand groove 14.
The present apparatus is simple and compact for structure, and armed lever can be rotated around main body, main body set two positioning holes, one
It is the positioning hole under armed lever deployed condition, another is the positioning hole under armed lever closure state, and two latch segments are pinched by hand,
Latch segment overcomes the elastic force of spring to be close to each other, and alignment pin is recovered to the inside of armed lever, can rotate armed lever, and armed lever turns to one
Positioning is postponed, and unclamps latch segment, and alignment pin is entered in corresponding positioning hole and locked, and prevents armed lever to be rotated further, this dress
Latch segment is put to be hidden into armed lever, it is more attractive in appearance.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
