Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the cross-sectional view of the utility model.
Specific implementation mode
In the utility model description, the orientation or positional relationship of the instructions such as term "upper", "lower", " preceding " and " rear " is base
In orientation or positional relationship shown in the drawings, it is merely for convenience of description the utility model rather than requires the utility model necessary
With specific azimuth configuration and operation, therefore should not be understood as limiting the present invention.
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings.
Referring to FIG. 1 and FIG. 2, a kind of locking device, including a locking member 1 and a lock tongue 2,1 middle part of locking member are provided with
One installation through-hole, in 2 movable setting installation through-hole of lock tongue, locking member 1 includes a locking main body 11, and 11 side of locking main body is set
Be set to tight lock part, the other side is set as mounting portion 12, several locking slots 13 are set in tight lock part side, if lock portion is cut into
The dry clamping block 14 being separated from each other, 14 middle part of clamping block are arranged to protrusion, and quantity, width and the depth of locking slot 13 can bases
Actual conditions change.
In use, mounting portion 12 is connect with attachment, and tight lock part is passed through to the connecting hole for being connected object from top to bottom
(during being somebody's turn to do, under the effect of external force, clamping block 14 is inwardly gathered, thus the protrusion at 14 middle part of clamping block can pass through and be connected
Connect the connecting hole of object), when needing attachment to connect locking with connected object, by the lock tongue 2 in 1 installation through-hole of locking member
It is pushed into tight lock part downwards, due to the supporting role of lock tongue 2, even if applying pulling force to locking member 1 from above, clamping block 14 can not
Inwardly gather, since 14 middle part of clamping block is provided with protrusion, thus tight lock part can not pass through connecting hole, to realize attachment
Locking between connected object is connect；When needing attachment to be detached with connected object, lock tongue 2 is pulled up so that lock tongue 2
Tight lock part is left, at this time under the effect of external force, clamping block 14 is gathered to middle part enables the protrusion at 14 middle part of clamping block to wear
The connecting hole for being connected object is crossed, to realize the separation of attachment and connected object.
The utility model is simple in structure, easy to operate, can quickly and conveniently realize between attachment and connected object
It locks and detaches, it is easy to process, it is at low cost.Simultaneously as lock tongue 2 is provided in the installation through-hole of locking member 1, due to lock tongue 2
Supporting role, during gathering with diastole, clamping block 14 11 junction of main body and does not stress clamping block 14 with locking, because
Without the junction damaged clamping block 14 with lock main body 11, it is made to strain and be broken off, thus this product long lifespan can be with
Reusability.
Preferably, locking main body 11 is cylindrical, and mounting portion 12 is provided with installation screw thread, and tight lock part is in cylinder
Shape, tight lock part include 4 symmetrically arranged clamping blocks 14, and clamping block 14 is elastic component, and elastic component can be plastics, and protrusion is round and smooth
Transition.Quantity can change with distribution according to actual conditions as soon as possible for locking main body 11, the concrete shape of tight lock part, card, have
The clamping block 14 of elasticity has toughness, is easy to gather and diastole, and is hardly damaged, protrusion it is round and smooth so that clamping block 14 outside
Connecting hole under the action of power along connected object is gathered, easy to operate simple.
Preferably, installation through-hole is arranged to stepped hole in 12 side of mounting portion, and lock tongue 2 is close to the side of tight lock part
It is provided with cascaded surface, a resetting spring 3 is provided between lock tongue 2 and locking member 1, the rank in lock tongue 2 is arranged in 3 one end of resetting spring
On tread, the other end is arranged on the end face of stepped hole.When without outer force effect, lock tongue 2 is pushed into tight lock part by resetting spring 3 to be made
Obtaining clamping block 14 cannot inwardly gather, so that attachment is in locking connection status with connected object.Lock tongue 2 is arranged simultaneously
The stepped hole of cascaded surface and installation through-hole setting lock tongue 2 can be prevented to be pulled away from installation through-hole.
Preferably, side of the lock tongue 2 far from locking member 1 is provided with handpiece 4, preferably round table-like, the hand of handpiece 4
Gripping member 4 is connected through a screw thread with lock tongue 2, is convenient for operating lock tongue 2 in this way.
According to the disclosure and teachings of the above specification, the utility model those skilled in the art can also be to above-mentioned reality
The mode of applying is changed and is changed.Therefore, the utility model is not limited to specific implementation mode disclosed and described above, right
