DETAILED DESCRIPTION

[0019] In order to further explain the technical scheme of the utility model, the following specific embodiments are described in detail.

[0020] Please refer to Figures 1-2 The utility model provides a convenient to install's camera lens barrel structure, including camera main body 1, the butt joint has the connecting pipe 2 in camera main body 1 front side, the butt joint has the sleeve 3 in connecting pipe 2 front side, install lens barrel main body 4 in sleeve 3 front side, still including the double butt joint assembly 5 for being located in the inside both sides of sleeve 3.

[0021] Please refer to Figures 3-4 The double butt joint assembly 5 in the embodiment includes the pin shaft 51 that is symmetrically movable and is installed inside the upper and lower two sides of the connecting pipe 2, the first spring 52 that can realize elastic external top locking support on one side of the pin shaft 51, the lock hole 53 that is symmetrically opened inside the sleeve 3 and is connected with the two side pin shafts 51, the push shaft 54 that is movably and vertically inserted inside the lock hole 53 and abuts on one side of the pin shaft 51, the quick external removal unlocking movement of the pin shaft 51 can be realized by extruding the push shaft 54, the side block 55 that is fastened on one side of the push shaft 54, the support rod 56 that is vertically inserted in the middle of the side block 55 for moving guide cooperation, the second spring 57 that is installed on the outer side of the support rod 56 and is connected with the outer side of the side block 55, and the elastic force of the second spring 57 is less than that of the first spring 52, so that the first spring 52 can efficiently and stably realize the insertion locking effect of the pin shaft 51 and the lock hole 53, secondly, the second spring 57 can quickly realize the movement reset of the side block 55 by elastic force back pulling support, and the clamping structure 58 that can improve the butt joint fastening of the lens barrel main body 4 and the connecting pipe 2 is butt joint on the other side of the push shaft 54.

[0022] The lock hole 53 is connected with the pin shaft 51 and the push shaft 54 respectively, and the pin shaft 51 and the push shaft 54 are vertically abutted and butt jointed, so that the push shaft 54 can extrude the pin shaft 51, and the quick unlocking of the pin shaft 51 is realized.

[0023] The clamping structure 58 includes the butt joint strip 581 that is butt jointed on the side of the push shaft 54, the sliding block 582 that is connected on the side of the butt joint strip 581 away from the push shaft 54, the moving plate 583 that is fastened on the side of the sliding block 582 away from the butt joint strip 581, and the moving plate 583 is slidably connected with the inside of the sleeve 3, the push-pull strip 584 that is butt jointed on the side of the moving plate 583, the protruding block 585 that is symmetrically and fastened on the inside of the push-pull strip 584, and the two side protruding blocks 585 are both arranged in the form of inclined strips, the vertical strip 586 that is vertically inserted in the inside of the push-pull strip 584 and is connected with the two side protruding blocks 585, the limiting plate 587 that is connected on the side of the vertical strip 586 and is used for moving limiting cooperation on the left and right two ends, and the clamping ring 588 that is installed on the other side of the vertical strip 586 and is connected with the outside of the connecting pipe 2.

[0024] The butt joint strip 581 is arranged transversely on the side of the push shaft 54, and the position of the butt joint strip 581 is horizontally opposite to the position of the side block 55, so that the butt joint strip 581 and the side block 55 can move up and down synchronously with the push shaft 54; the middle part of the sliding block 582 is integrally provided with an inclined groove, and the inclined groove of the sliding block 582 is connected with the middle part of the side of the butt joint strip 581, so that the sliding block 582 can slide back and forth flexibly through the butt joint effect of the inclined groove in the middle part of the sliding block 582 and the butt joint strip 581; the convex blocks 585 are arranged obliquely along the inside of the push-pull strip 584, and the two convex blocks 585 are respectively slidably embedded in the inside of the vertical strip 586, so that when the push-pull strip 584 moves, the synchronous movement of the two convex blocks 585 arranged on the inside can be realized, and when the two convex blocks 585 move, the vertical strip 586 inserted in the inside of the push-pull strip 584 will move up and down.

[0025] The working principle is as follows:

[0026] When the docking activity of the lens barrel body 4 and the camera body 1 is to be implemented, the sleeve 3 at the rear side of the lens barrel body 4 can be docked with the connecting pipe 2 provided at the front side of the camera body 1. When the sleeve 3 is sleeved outside the connecting pipe 2, the pin shaft 51 provided inside the connecting pipe 2 will be extruded, and the two pin shafts 51 will be synchronously compressed on one side with the first spring 52. When the pin shaft 51 is in the contracted state and moves to the lock hole 53 provided inside the sleeve 3, the first spring 52 will rebound to realize the outer top activity of the pin shaft 51. In this way, the two pin shafts 51 will be quickly inserted into the corresponding lock hole 53 inside to realize the quick insertion and combination of the sleeve 3 and the connecting pipe 2. At the same time, when the pin shaft 51 is inserted into the lock hole 53, the push shaft 54 inside the vertical activity insertion of the lock hole 53 will be pushed by the elastic force of the first spring 52 to realize the self-moving activity of the push shaft 54. With the movement of the push shaft 54, the movement of the two side blocks 55 and the docking bars 581 respectively provided thereon will be synchronously realized. When the side block 55 moves, it will stably move along the support rod 56 inserted in the middle part. In this way, the second spring 57 provided outside the support rod 56 will be stretched, and the second spring 57 will be prepared for subsequent elastic back-pulling. When the docking bar 581 moves, it will be transmitted with the inclined groove provided inside the sliding block 582 to realize the whole pushing of the sliding block 582. With the movement of the sliding block 582, the moving plate 583 docked on one side of the sliding block 582 can realize the pushing of the push-pull bar 584 on the side edge. In this way, the vertical bar 586 inserted into the push-pull bar 584 and connected with the protrusions 585 provided on both sides of the push-pull bar 584 can move to the outside of the connecting pipe 2 through the sliding effect of the two protrusions 585 to make the clamping ring 588 docked on one side of the vertical bar 586 clamped with the outside of the connecting pipe 2, so that the docking fastening of the connecting pipe 2 and the sleeve 3 is further improved. In this way, the clamping effect of the pin shaft 51, the lock hole 53 and the two clamping rings 588 can realize the double docking fastening of the connecting pipe 2 and the sleeve 3, and the docking fastening of the camera body 1 and the lens barrel body 4.

[0027] When the lens barrel body 4 needs to be disassembled subsequently, the two push shafts 54 on both sides can be extruded to make the pin shafts 51 on both sides abut against each other, so that the pin shafts 51 on both sides can be moved out of the lock hole 53 to achieve quick unlocking. At the same time, the other side of the docking bar 581 will be driven to make the docking bar 581 transmitted with the inclined groove provided in the middle part of the sliding block 582 to realize the back-pulling of the sliding block 582. With the back movement of the sliding block 582, the moving plate 583 docked on the side edge of the sliding block 582 will synchronously pull back the whole push-pull bar 584 to make the vertical bar 586 connected with the protrusions 585 provided on both sides of the push-pull bar 584 realize the movement reset activity. In this way, the clamping and fastening effect of the clamping ring 588 on the connecting pipe 2 can be quickly released to achieve the simultaneous release of the double docking fastening state, so as to ensure the quick disassembly of the lens barrel body 4 and the camera body 1.
