Problems solved by technology

[0002] The existing folding caster mechanism is controlled by multiple operating mechanisms, that is, two handles are used to control the unlocking or locking of the retracted state and the unfolded state of the folding caster mechanism respectively. Each handle requires a separate linkage mechanism, resulting in an overall internal structure. more complex and takes up more space
When operating, because there are two identical handles, it is easy to cause confusion, and the operation process is not efficient

Embodiment Construction

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0021] The single-handle operation self-locking folding caster of the present invention is composed of a housing 1, an operating mechanism, and a universal wheel mechanism, see image 3 , the housing 1 is a rectangular box, which contains an operating mechanism;

[0022] The operating mechanism includes a torsion spring 2, a hook shaft 3, and a hook 4; the torsion spring 2 and the hook 4 are sleeved on the hook shaft 3, and the torsion spring 2 stretches out a set of outer legs and a set of inner legs, respectively It is in close contact with the inner wall of the housing 1 and the inclined plate of the hook 4 and generates a clockwise pre-tightening force. The hook 4 is composed of a swivel, a vertical lock around the swivel, a horizontal lock and a slant plate, two of which The locks are perpendicular to each other, the inclined plate forms an acute angle ...

Abstract

The invention relates to a single handle operation self-locking folding caster, which is composed of a housing (1), an operating mechanism and a universal wheel mechanism; the housing (1) contains the operating mechanism; the operating mechanism includes a torsion spring (2), a hook A rotating shaft (3) and a hook (4); the universal wheel mechanism includes a wheel seat (8), a universal wheel (9) and a wheel buckle (7) connected to the universal wheel (9). The present invention can realize the locking of two states of folding wheel retracted and put down by one operating mechanism at the same time, realizes the automatic locking of the folding wheel mechanism, the unlocking operation is simpler, and the volume of the whole mechanism is greatly reduced, so as to be applicable to various scenes.

Description

technical field [0001] The invention belongs to the field of adjustment mechanisms, and relates to a single-handle-operated folding caster with a self-locking function, in particular to a self-locking mechanism that realizes two-state unlocking only by a single handle. Background technique [0002] The existing folding caster mechanism is controlled by multiple operating mechanisms, that is, two handles are used to control the unlocking or locking of the retracted state and the unfolded state of the folding caster mechanism respectively. Each handle requires a separate linkage mechanism, resulting in an overall internal structure. More complex and takes up more space. During operation, because there are two identical handles, it is easy to cause confusion, and the efficiency of the operation process is not high. Contents of the invention [0003] Purpose of the present invention: [0004] The purpose of the present invention is to propose a single-handle operation self-l...
