The utility model provides a pair of quick detach structure and lighting device who has this structure, its work piece principle as follows:

the working principle is as follows: the spring 5 is placed into a spring groove of the locking block 3, then the steel ball 4 is placed, when the wrench 6 is slowly pushed into a matching circle of the locking block 3, the wrench 6 can only be kept at an initial position or a reaching position under the action of the spring 5 pushing the steel ball, the wrench 6 and the inclined surface of the locking block 3 act on the steel ball 4 together under the condition that the wrench 6 is stirred by external force, the steel ball 4 applies force to the spring 5, and at the boundary of the switching wrench 6, the steel ball 4 is guaranteed to be switched, locked and unlocked by the external force under the thrust action of the spring 5; meanwhile, the wrench 6 is exactly the same as the moving direction of the locking block part and the lamp body part at the locking position, because the runway of the whole lamp body part is U-shaped, when the locking block part slides to the extreme end of the runway of the lamp body part, the locking block part can not move forwards, then the wrench 6 of the sliding block part is in the middle again, at the moment, the wrench 6 buckles the groove of the lamp body part, and the locking block part can not move backwards, thereby achieving the function of quick-release locking; when the spanner 6 of the sliding block part is in the unlocked position, the gap direction of the spanner 6 is parallel to the moving direction, and the locking block part can slide out along the track; and finishing the function of quick-release unlocking. The locking piece part and the lamp body part have a gap in assembly due to the matching relationship of the metal pieces, and the gap between the locking piece part and the lamp body part is extruded by utilizing the compression of the waterproof ring, so that the relative stability of the two metal pieces is realized. Adapter 8 takes two forks of aperture to insert cup screw 2 in the slot of locking piece 3, pass the hole that the locking piece 3 area cup was dodged the position and pass adapter 8's through-hole, then to the thread hole of locking piece 3, last contact surface and the last contact surface of locking piece 3 through adapter 8, and the side of installing joint 8 and locking piece 3's side, two facial features cooperate, plus tightening up of cup screw 2, guaranteed install joint 8 and locking piece 3's cooperation above with, the meticulous cooperation of side and side, the more effective product of having fixed.

The utility model provides a pair of quick detach structure and have lighting device of this structure has following advantage:

1. adapter 8 takes two forks of aperture to insert in the slot of locking piece 3, cup head screw 2 passes the hole that the cup head was dodged to the locking piece 3 area and passes adapter 8's through-hole, then to the thread hole of locking piece 3, the last contact surface through adapter 8 and the last contact surface of locking piece 3, and the side of installing joint 8 and the side of locking piece 3, two facial features cooperate, plus tightening up of cup head screw 2, guaranteed install joint 8 and locking piece 3's cooperation above with, the side is with a kind of the meticulous complex cooperation mode of side.

2. The locking piece part and the lamp body part can realize a relative sliding matching mode due to the matching of the convex rail surface of the locking piece 3 and the concave rail surface of the lamp body 1.

3. The wrench 6 rotates by taking the round hole of the locking block 3 as an axial direction, and the range is limited in the slot position given by the locking block 3; the spring 5 pushes against the steel ball 4, because of the rotation of the steel ball 4, the steel ball 4 will be stopped at the place where both left and right are stressed, when the steel ball 4 pushes against the surface (locking switching surface 63) of the wrench 6 close to the rotating shaft in the natural state, the force is continuously applied, the position right above the locating slot of the locking block 3 is pushed against, so the state reaches the balance, which is the locking state of fig. 4; when the wrench 6 is pulled by an external force, the arc surface close to the rotating shaft is switched to an unlocking surface (i.e. the unlocking switching surface 62) from the locking surface of the wrench 6 due to the spring being pressed when the wrench 6 rotates, namely, the unlocking state of fig. 2, and the switching between the locking state and the unlocking state is quick and reliable.

4. When the locking block part slides into the lamp body part from the convex guide rail of the locking block 3, the guide groove of the wrench 6 forms a gap, at the moment, the gap (as shown in figure 5) is utilized, the main body of the locking block part slides into the groove bottom of the lamp body, the wrench 6 of the locking block part is shifted to the center position from the side edge, so that the locking structure is achieved, and after the locking block part is used, the wrench 6 of the locking block part only needs to be shifted to the side edge from the center, and the quick release can be completed by pushing the locking block part.

5. When the locking block part slides into the lamp body part, a certain fit clearance exists due to the fit of the metal slide rails, the quick-release part with the fit clearance can shake, a chamfer is added at the fit part of the locking block 3, and a chamfer is added at the cut-in opening of the lamp body part, so that smooth access is facilitated; increase a waterproof circle on the lamp body of lamp body part, absorb locking piece part and lamp body part fit clearance, reduce quick detach structure's rocking.

The foregoing is a more detailed description of the present invention, taken in conjunction with the specific preferred embodiments thereof, and it is not intended that the invention be limited to the specific embodiments shown and described. To the utility model belongs to the technical field of ordinary technical personnel, do not deviate from the utility model discloses under the prerequisite of design, can also make a plurality of simple deductions or replacement, all should regard as belonging to the utility model discloses a protection scope.
