Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The following describes the implementation of the present invention in detail with reference to specific embodiments.

Referring to fig. 1, in an embodiment of the present invention, an assembly mechanism for automatic locking is provided, which includes a hollow housing 1 having an open end and a closed end, and an inner cylinder 2 for being installed in the housing.

Referring to fig. 2, a protruding cavity 11 protruding outward is formed on one side wall of the housing 1. An elastic blocking part 12 protruding out of the protruding cavity 11 is arranged in the protruding cavity 11.

One side of the inner cylinder 2 is provided with a blocking groove 21 corresponding to the elastic blocking part 12. When the inner cylinder 2 is pushed into the outer cover 1, the inner cylinder 2 compresses the elastic blocking part 12 into the protrusion cavity 11, and when the inner cylinder 2 is completely pushed into the outer cover 1, the elastic blocking part 12 bounces and extends into the blocking groove 21, so that the inner cylinder 2 is fixed in the outer cover 1.

Specifically, the elastic blocking member 12 includes a first tongue 13 and a first spring 14. The first tongue 13 includes a first tongue head 131 and a first tongue neck 132. The bottom of the protruding cavity 11 is provided with an opening (not labeled) for the first tongue neck 132 to pass through, the first spring 14 is sleeved on the first tongue neck 132, and two ends of the first spring respectively abut against the first tongue head 131 and the bottom of the protruding cavity 11. The first tongue neck 132 is provided with a first screw 133 inserted from the bottom end of the first tongue neck 132, and the size of the nut of the first screw 133 is larger than that of the opening, so as to position and fix the first tongue 13 in the protrusion cavity 11. The first reed head 131 includes a ramp (not shown) having an opening direction toward the housing 1, so that the ramp can be compressed during the process of loading the inner barrel 2 into the housing 1, so that the first reed head 131 is fully compressed into the protrusion cavity 11 without blocking the inner barrel 2 from being pushed into the housing 1.

A jacking component (not marked) for jacking the elastic blocking component is arranged in the inner cylinder 2, the jacking component is arranged right opposite to the head of the first reed, and one end of the jacking component extends into the blocking groove 21. Specifically, the jacking member includes a second tongue 22, a second spring 23, a stopper 24, and a second screw 25. The second tongue 22 includes a second tongue head 221 and a second tongue neck 222, and the second spring 23 is sleeved on the second tongue neck 222. The stopper 24 is disposed at a bottom edge of the second tongue neck portion 222, and the second screw 25 is inserted from the bottom of the second tongue neck portion 222 to fix the stopper 24 and the second tongue neck portion 222. The inner wall of the blocking groove 21 is provided with a protrusion 211 which abuts against the stopper 24, and the protrusion 211 is used for limiting the stopper 24, so as to limit the second tongue 22 and prevent the second tongue 22 from separating from the blocking groove 21.

Referring to fig. 3 and 4, the inner cylinder 2 further includes a cam 26 disposed adjacent to the tongue head 221 and an inner cylinder handle 28 connected to the cam 26. The cam 26 has a cam shaft 261, and the inner cylinder handle 28 fixes the cam shaft 261 by a screw 29. When the inner cylinder handle 28 rotates, the cam 26 is driven to rotate, so that the vertex of the cam rotating shaft 261 presses the second tongue 22, and the second tongue 22 lifts up the first tongue 13. A torsional spring 27 is established to the cover on the cam pivot 261, the both ends of torsional spring 27 respectively with the cam pivot 261 with the inner tube 2 is fixed mutually, thereby makes to loosen behind the inner tube handle 28 under the torsion effect of torsional spring 27, the cam pivot 261 drives the inner tube handle 28 resets.

The assembly process of the automatic locking assembly mechanism is as follows:

the inner cylinder 2 is pushed in from the opening end of the outer cover 1, the inner cylinder 2 compresses the inclined plane, so that the first reed head 131 is completely compressed to the protrusion cavity 11 without blocking the inner cylinder 2 from further pushing into the outer cover 1, when the inner cylinder 2 completely enters the outer cover 1, the blocking groove 21 is positioned right above the first reed 13, at this time, the first reed 13 is not pressed by the inner cylinder 2, and bounces up and extends into the blocking groove 21 under the action of the first spring 14, so that the inner cylinder 2 is fixed in the outer cover 1.

The disassembly process of the automatic locking assembly mechanism is as follows:

the inner cylinder handle 28 is pulled by rotation, so that the cam 26 rotates, the vertex of the cam 26 compresses the second tongue 22, the second tongue 22 jacks the first tongue 13, the first tongue 13 is just compressed into the protrusion cavity 11, the inner cylinder 2 cannot be limited, and then the inner cylinder 2 is pulled out. The inner barrel handle 28 is then released and the inner barrel handle 28 returns under the force of the torsion spring 27.

In conclusion, adopt the utility model discloses an automatic locking's assembly devices, will the inner tube pushes away during the dustcoat, the inner tube will elasticity blocks the part compression extremely in protruding cavity, works as the inner tube pushes away completely during the dustcoat, elasticity blocks the part and upsets, and stretches into in the catch groove, will the inner tube is fixed in the dustcoat, can realize the locking of inner tube and dustcoat fast, improve the efficiency of assembly.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
