Detailed Description

The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.

In the present invention, unless otherwise specified, the terms "distal, proximal, upper, lower, inner, outer" and the like are used in the terminology in an orientation of conventional usage only or in a colloquial sense understood by those skilled in the art, and should not be construed as limiting the terms.

Referring to fig. 1 and 2, the present invention provides a rotatable handle assembly mechanism comprising a bracket 1 having a receiving cavity, a handle 2, a pin 3 and a locking assembly; wherein the content of the first and second substances,

the pin shaft 3 penetrates through corresponding through holes on the bracket 1 and the handle 2 to rotatably mount the handle 2 on the bracket 1, so that the handle 2 rotates in a plane vertical to the bracket 1 by taking the pin shaft 3 as an axis;

the locking assembly is arranged on the bracket 1 and positioned at one side of the handle 2 and used for locking the handle 2; so that

When the locking device is needed to be used, the locking assembly is unlocked, the holding part of the locking assembly is rotated to the outside of the bracket 1 from the accommodating cavity by rotating the handle 2, and the handle 2 can be fixed to be used by locking the locking assembly again;

after the use, unblock locking Assembly again, make its portion of gripping continue to rotate and accomodate to holding in the chamber again through rotatory handle 2, the locking Assembly can hide handle 2 again this moment.

In the use, discover the fixed pivot of ordinary pin, pack into the hole axle with the pin through interference fit, the assembly process is difficult to control, and the application is difficult after the assembly, and the reassembling easily causes outward appearance coating damage scheduling problem after the application.

Therefore, in the present embodiment, in order to facilitate quick positioning, mounting and dismounting of the handle 2, it is preferable that the end of the pin shaft 3 is formed with a screw thread, as shown in fig. 3, and is fixed to the bracket 1 by a screw connection. Like this, detachable round pin axle has convenient the dismantlement, and the easy accurate control of size, assembly process do not deform, round pin axle fixed advantage such as firm difficult droing can satisfy the operation requirement under the vibration operational environment.

In order to optimize the structure of the locking assembly, the locking assembly preferably comprises a sliding block 4 and a button 5 (see fig. 4), wherein a locking bulge 6 is formed on the sliding block 4 at a position which is close to the handle 2 in a protruding mode, and a locking blind hole 15 which can be matched with the locking bulge 6 is formed on the handle 2;

the side walls of two sides of the sliding block 4 close to the locking bulge 6 are provided with downward inclined through guide grooves 7, the button 5 is provided with a sliding column 8 which can be embedded in the through guide grooves 7 in a sliding manner, and the bottom end of the button 5 encapsulates a spring 10 on the handle 2 through a cover plate 9; so that

When the button 5 is pressed (see fig. 6), the slide block 4 is driven by the button 5 to retract into the accommodating cavity, and the handle 2 is in an unlocking state and can rotate freely;

when the button 5 is released (see fig. 5), the sliding block 4 is driven by the spring 10 to extend into the locking blind hole, and the handle 2 is in a locking state and cannot rotate.

In order to facilitate the fixing of the handle 2, the rotation of the handle 2 is limited to 0-180 °, and preferably, a limiting projection 11 is formed on the end of the handle 2 remote from the locking assembly. When the handle 2 rotates to approach the maximum limit, the limiting bulge 11 is abutted against the bracket 1 to timely stop the bracket from continuously rotating for a certain angle.

In addition, the button 5 is formed with a guide block 12 slidably fitted on the bracket 1 to ensure that the button 5 keeps reciprocating in a vertical direction.

Similarly, in fig. 7, the cover plate 9 is formed with spring guide posts 13 extending into the spring 10 to define the position and movement direction of the spring 10, so that the structure between the various parts is more compact and the movement process is smoother.

In addition, in order to facilitate quick installation of the rotatable handle assembly mechanism to a desired position, it is preferable that both ends of the bracket 1 are detachably fixed to the installation position by screws 14 as shown in fig. 8. Therefore, the handle assembly is integrated and independently installed, can be installed on various products according to requirements, and is easy to process, disassemble and convenient to maintain.

Through the technical scheme, the design mode of the detachable rotating shaft is adopted, so that the product is convenient to assemble. During the use, all can fix the handle when not using, through the design of slider, the vertical motion who will press converts the horizontal motion of slider into, realizes the fixed of handle, satisfies handle assembly's resistant vibration requirement.
