This application is a U.S. National Stage entry under 35 U.S.C. ยง 371 based on International Application No. PCT/CN2016/114037, filed on Dec. 31, 2016, which was published under PCT Article 21(2) and which claims priority to Chinese Patent Application No. 201610719590.2, filed on Aug. 25, 2016. The embodiment of the priority applications are hereby incorporated herein in their entirety by reference.
The present disclosure relates to a locking buckle structure, and in particular to a sliding-type locking buckle which can slide in any traveling range and can be positioned at any position within the traveling range.
Many items in daily life comprise two parts that are connected by a locking buckle, for example, an elastic ring-shaped band such as a headband of a headgear, and a strap of an article. In the prior art, the locking buckles used in such items generally comprises a common plastic locking buckle and a plastic locking buckle with a sliding switch.
Specifically, as shown in
A sliding-type locking buckle, comprising a casing and a locking buckle body mounted on the casing, wherein
the casing comprises an upper casing, a lower casing and an inner cavity enclosed by the upper casing and the lower casing, and the upper casing and the lower casing are fixedly connected together;
the locking buckle body comprises an upper body, a lower body and a compression spring located between the upper body and the lower body;
the upper casing is provided with an upper sliding slot penetrating the upper casing in its thickness direction, and a plurality of sawteeth are disposed on an inner wall of the upper casing along a length direction of the upper sliding slot;
the lower body is located in the inner cavity, and a top of the upper body protrudes out of the upper sliding slot;
a lateral surface of the upper body is provided with a limiting protrusion which is disposed in the inner cavity of the casing, and the limiting protrusion is provided with a sawtooth portion matching the sawteeth on the inner wall of the upper casing.
Optionally, the sawteeth are provided at both lateral sides of the upper sliding slot in the length direction.
Optionally, a mounting post is fixed on a lower surface of the upper body, a mounting hole is provided on the lower body, a bottom end of the mounting post is inserted into the mounting hole, and the compression spring is sleeved on the mounting post.
Optionally, a sliding guide post is fixed on the lower surface of the lower body, the lower casing is provided with a lower sliding slot, the length direction of the lower sliding slot is parallel to the length direction of the upper sliding slot, and the sliding guide post is embedded in the lower sliding slot.
Optionally, the lower body is provided with a guide groove, and a lower portion of the upper body is embedded in the guide groove.
Optionally, the upper casing and the lower casing are integrally fixed by screws.
The technical solutions of the present disclosure are further described in detail below with reference to the accompanying drawings and specific embodiments.
Compared with the prior art, the sliding-type locking buckle according to the present disclosure can achieve the sliding in any traveling range by pressing the locking buckle body and making the locking buckle body slide along the length direction of the upper sliding slot. When the locking buckle body needs stopping, one may just release the locking buckle body, so that the sawtooth portion on the upper body are engaged with the sawteeth on the upper casing, thereby stopping the locking buckle body at any position within the traveling range. Moreover, by changing the tooth width of the sawteeth, different adjustable sliding ranges can be achieved.
Referring to
The locking buckle body is placed in the inner cavity 30 of the casing through the upper sliding slot 11, and is restrained in the upward direction by the limiting protrusion 41 on the lateral surface thereof to prevent it from coming out of the inner cavity 30. The compression spring 60 is disposed between the upper body 40 and the lower body 50 of the locking buckle body, so that the upper body 40 can be pressed, and when no external force is applied, the limiting protrusion 41 of the upper body 40 abuts against the inner wall of the upper casing 10 under the elastic force of the compression spring 60, and the sawtooth portion 42 on the limiting protrusion 41 engages with the sawteeth 12 on the inner wall of the upper casing 10. At the same time, the lower body 50 abuts against the inner wall the lower casing 20 under the elastic force of the compression spring 60, thereby achieving the stopping and positioning of the locking buckle body.
When the locking buckle body needs sliding, one may just press the upper body 40 downwardly to disengage the sawtooth portion 42 from the sawteeth 12 on the inner wall of the upper casing 10, and move the upper body 40 along the length direction of the upper sliding slot 11, and drive the lower body 50 and the compression spring 60 to slide together, thereby achieving the sliding in any traveling range within the length of the upper sliding slot 11.
When the locking buckle body needs stopping, one may just release the upper body 40, so that the sawtooth portion 42 on the upper body engages with the sawteeth 12 on the upper casing 10, as shown in
The fixed connection of the upper casing 10 and the lower casing 20 may be achieved by screws or gluing, etc.
Referring to
Further, as shown in
In order to further make the locking buckle body slide smoothly and reduce the friction, as shown in
Similarly, in order to guide the up and down movement of the upper body 40 of the locking buckle body, as shown in
The above embodiments are only intended to illustrate the technical solutions of the present disclosure, and are not to limit the present disclosure. Although the present disclosure is described in detail with reference to the above embodiments, a person skilled in the art may still modify the technical solutions set forth in the above embodiments, or equivalently substitute part of the technical features of them. However, those modifications or substitutions do not make the essence of the corresponding technical solutions depart from the spirit and scope of the claimed technical solutions of the present disclosure.
