Abstract
Description
Technical Field
[0001] This utility model relates to an adjuster, specifically a locking adjustment device. Background Technology
[0002] Traditional locking and adjusting devices generally suffer from problems such as complex structure, low adjustment efficiency, and insufficient locking reliability. For example, some devices rely on screws for fixing, which are cumbersome to install and disassemble and are prone to loosening; others use spring clip designs, and the elastic components are prone to aging and failure after long-term use, leading to safety hazards. Utility Model Content
[0003] In view of the above problems, this utility model proposes a locking adjustment device.
[0004] The technical solution of this utility model:
[0005] A locking adjustment device includes a base mounted on a webbing; the locking adjustment device also includes a clamping plate, the base being disposed in front of a connecting plate and the clamping plate being disposed behind the connecting plate, the base and the clamping plate being connected and clamping the connecting plate by a snap-fit structure; the base moves up and down along the webbing, causing the connecting plate to move up and down; the snap-fit structure includes a clip and a slot, the clip being disposed on the rear side of the base and the slot being disposed on the front side of the clamping plate, the end of the clip extending through the connecting plate into the slot, the base and the clamping plate moving relative to each other, the end of the clip moving along the slot and reciprocating between a loose position and a fastened position, the loose position being an opening or notch for the end of the clip to enter / exit, and the fastened position including a locking platform capable of engaging with the end of the clip.
[0006] To further improve the above technical solution, a backstop structure is designed, including a stop block and an elastic clip. The stop block is located on the rear side of the base, and the elastic clip is located on the front side of the clamping plate. The end of the stop block extends through the connecting plate and cooperates with the elastic clip to form a snap-fit structure for backstop limiting.
[0007] The above technical solution has been further improved by adding four sets of buckle structures, which are placed at the four corners; the anti-reverse structure is centered; the layout is more reasonable, making the connection between the base and the clamp plate firm and stable.
[0008] A further improvement to the above technical solution is that when the base and the clamping plate clamp the connecting plate, the rear side of the base is in contact with the front side of the connecting plate, and the front side of the clamping plate is in contact with the rear side of the connecting plate. This results in a large contact area and high frictional resistance, preventing accidental relative movement between the base and the clamping plate, thus ensuring a firm and stable connection between them.
[0009] The above technical solution is further improved by moving the clamping plate up and down to make the base and the clamping plate move relative to each other; anti-slip protrusions are distributed on the rear side of the base.
[0010] In a further improvement to the above technical solution, the locking adjustment device also includes a flap, which is mounted on the base; the webbing is clamped between the flap and the base, and the flap opens to release the webbing, and the flap closes to clamp the webbing.
[0011] A further improvement to the above technical solution is that when clamping the webbing, the pressing part of the flip plate presses on the webbing and is toothed.
[0012] The above technical solution is further improved by flipping the flap downwards to open and upwards to close, which can prevent accidental opening.
[0013] A further improvement to the above technical solution is that the flip plate has a hole, which is a buckle hole that can accommodate a finger.
[0014] The advantages of this utility model are that it has a reasonable design and simple structure. Through the innovative design of the snap-fit structure, it realizes a functional closed loop of "quick installation - flexible adjustment - reliable locking", and has the advantages of compact structure, convenient operation and strong applicability.

[0019] In the diagram, 1 is the base, 2 is the clamping plate, 3 is the flip plate, 4 is the buckle structure, 4-1 is the clip, 4-2 is the slot, 5 is the anti-slip protrusion, 6 is the buckle hole, 7 is the anti-reverse structure, 7-1 is the stop block, and 7-2 is the elastic clip. Detailed Implementation
[0020] like Figure 1-4 As shown, a locking adjustment device includes a base 1, a clamping plate 2, and a flip plate 3. The base 1 and the clamping plate 2 are connected by four sets of snap-fit structures 4. The flip plate 3 is installed on the base 1. Anti-slip protrusions 5 are distributed on the rear side of the base 1. The four sets of snap-fit structures 4 are placed at the four corners. The pressing part of the flip plate 3 is toothed. The flip plate 3 has a hole, which is a buckle hole 6 that can accommodate a finger.
[0021] The buckle structure 4 includes a clip 4-1 and a slot 4-2. The clip 4-1 is located on the rear side of the base 1, and the slot 4-2 is located on the front side of the clamp 2. The slot 4-2 includes a release position and a fastening position. The release position is an opening for the end of the clip 4-1 to enter / exit, and the fastening position includes a locking platform that can fasten with the end of the clip 4-1.
[0022] The anti-reverse structure 7 includes a stop block 7-1 and an elastic clip 7-2. The stop block 7-1 is located on the rear side of the base 1, and the elastic clip 7-2 is located on the front side of the clamping plate 2.
[0023] When the above-mentioned locking adjustment device is in use, the webbing (sewn to the backpack at both ends) is clamped between the flip plate 3 and the base 1; the connecting plate (connected to the backpack shoulder strap) is clamped between the base 1 and the clamping plate 2. Specifically, the end of the clip 4-1 passes through the connecting plate and extends into the slot 4-2 (at this time, the end of the clip 4-1 is in the loose position), the end of the stop block 7-1 extends through the connecting plate and presses on the elastic clip 7-2 (causing the elastic clip 7-2 to deform), the clamping plate 2 moves downward, causing the slot 4-2 and the elastic clip 7-2 to move downward, the end of the clip 4-1 moves to the fastening position (the clip 4-1 and the slot 4-2 fasten), the elastic clip 7-2 passes around the end of the stop block 7-1 (the elastic clip 7-2 springs back) and abuts against the lower end surface of the stop block 7-1 (forming the anti-reverse limit of the buckle structure 4).
[0024] (Press your finger into the buckle hole 6) Flip down to open the flap 3, loosen the webbing, and move the base 1 up and down along the webbing to move the connecting plate up and down, adjusting the tightness of the backpack shoulder straps; flip up to close the flap 3, clamp the webbing, and lock the base 1 to fix the connecting plate.
[0025] The above embodiments are only for illustrating the technical concept and features of the invention, and are intended to enable those skilled in the art to understand the content of the invention and implement it accordingly. They should not be construed as limiting the scope of protection of the invention. All equivalent changes or modifications made in accordance with the spirit and essence of the invention should be covered within the scope of protection of the invention.
