Detailed Description

In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the following description of the present invention is provided with reference to the accompanying drawings, which are only some embodiments of the present invention, and it is obvious for a person skilled in the art to obtain other drawings without creative efforts.

As shown in fig. 1 to 7, the utility model discloses a depression bar length adjustment structure of button subassembly of an embodiment, including button body 10 and depression bar 20, during button body 10 was packed into to the one end of depression bar 20, the other end stretches out button body 10, still including the movable lock catch 30 of connecting on button body 10, lock catch 30 can be at the limiting position and step down the position between the activity, when limiting position, lock catch 30 was spacing mutually so that depression bar 20 and button body 10 are spacing in the axial of depression bar 20 with depression bar 20, when stepping down the position, lock catch 30 relieved the depression bar 20 spacing so that depression bar 20 can stretch out and draw back along the axial slip of depression bar 20 for button body 10.

In this embodiment, the press rod 20 is provided with the engaging portions 21 at intervals along the axial direction, the lock catch 30 is provided with the limiting portions 31 engaged with the engaging portions 21, when in the limiting position, the limiting portions 31 of the lock catch 30 are in limiting engagement with the engaging portions 21, and when in the receding position, the limiting portions 31 of the lock catch 30 are staggered from the engaging portions 21 to release the axial limiting of the press rod 20. The latch 30 is rotatably attached to the button body 10 to move between a retaining position and a yield position.

In this embodiment, the outer peripheral wall of the pressing rod 20 extends axially to form a sliding groove 22, the matching portion 21 and the sliding groove 22 are arranged along the circumferential direction of the pressing rod 20, the lock catch 30 can be rotatably sleeved outside the pressing rod 20, and when the pressing rod 20 is at the abdicating position, the limiting portion 31 of the lock catch 30 corresponds to the sliding groove 22 and can axially slide along the sliding groove 22, so that the pressing rod 20 and the button body 10 can axially extend and retract.

Specifically, the matching portion 21 is a row of clamping grooves extending along the axial direction on the outer peripheral wall of the pressing rod 20, the limiting portion 31 is arranged on the inner peripheral wall of the lock catch 30, and the limiting portion 31 is a clamping rib corresponding to the clamping grooves. Alternatively, the engaging groove of the engaging portion 21 may be replaced by an outer thread (not shown), and the engaging rib of the stopper portion 31 may be replaced by an inner thread engaged with the outer thread.

In this embodiment, the button body 10 is provided with a cylinder 11, the pressing rod 20 is telescopically engaged with the cylinder 11, the latch 30 is rotatably attached to an end of the cylinder 11, and a groove 111 for rotating the latch 30 is provided at the end of the cylinder 11. A limiting structure for limiting the rotation of the latch 30 is provided between the latch 30 and the button body 10, or a limiting structure for limiting the rotation of the latch 30 is provided between the latch 30 and the pressing rod 20. The limiting structure adopts the protruding muscle that is equipped with on the depression bar 20, when hasp 30 rotated to with protruding muscle looks butt, hasp 30 was spacing and unable continuation rotation by protruding muscle to make hasp 30 accurate activity to stepping down position or limiting position, and need exert certain power to hasp 30 and just can cross protruding muscle and make its rotation. Specifically, in this embodiment, the ribs include a first rib 211 for limiting the movement of the lock catch 30 to the limiting position, and a second rib 221 for limiting the movement of the lock catch 30 to the yielding position. Of course, the ribs may be replaced by bumps or bumps.

The length adjustment process of the compression bar in this embodiment is briefly described as follows:

first, as shown in fig. 4 and 5, the sliding groove 22 of the pressing rod 20 corresponds to the position of the limiting portion 31 of the latch 30, and at this time, the latch 30 is at the abdicating position for abdicating the pressing rod 20, so that the pressing rod 20 can be axially inserted into the cylinder portion 11, and the pressing rod 20 is telescopically adjusted relative to the cylinder portion 11 to adjust the length of the exposed portion of the pressing rod 20 to a predetermined value.

Next, as shown in fig. 6 and 7, the lock catch 30 is rotated by a predetermined angle (for example, 90 degrees) to make the lock catch 30 located at a position limiting the pressing rod 20, and at this time, the limiting portion 31 goes over the first rib 211 and is embedded into the mating portion 21 (slot), so that axial limiting is achieved between the pressing rod 20 and the button body 10, and the pressing rod 20 cannot move telescopically relative to the cylinder portion 11, so as to fix the length of the exposed portion of the pressing rod 20. After the limiting part 31 crosses the first convex rib 211 and is embedded into the matching part 21 (clamping groove), the first convex rib 211 prevents the limiting part 31 from exiting from the matching part 21, so that the pressing rod 20 is ensured not to be loosened and run, the adjustment is convenient, and the function is reliable.

When the length of the exposed portion of the pressing rod 20 needs to be adjusted again, the lock catch 30 only needs to be rotated reversely by the preset angle (for example, 90 degrees), so that the lock catch 30 returns to the abdicating position for abdicating the pressing rod 20, in the process, the second convex rib 221 limits the rotation angle of the lock catch 30, and the situation that the sliding groove 22 of the pressing rod 20 cannot correspond to the limiting portion 31 of the lock catch 30 due to the too large rotation angle of the lock catch 30 is avoided.

As shown in fig. 8 to 10, a difference between the present embodiment and the above-mentioned embodiment is that the lock catch 30 of the present embodiment is slidably attached to the button body 10 to move between the limiting position and the yielding position. In this embodiment, the lock catch 30 is slidably attached to the end of the barrel 11, and a groove 111 for sliding the lock catch 30 is provided at the end of the barrel 11.

Similarly, a stopper structure (not shown) for stopping the sliding of the latch 30 is provided between the latch 30 and the button body 10, or a stopper structure (not shown) for stopping the sliding of the latch 30 is provided between the latch 30 and the press lever 20. The limiting structure comprises a first limiting structure used for limiting the movement of the lock catch 30 to a limiting position and a second limiting structure used for limiting the movement of the lock catch 30 to a yielding position.

The length adjustment process of the pressing rod of this embodiment is substantially the same as that of the above embodiment, and is not described herein again.

While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
