Technical Field

[0001] The utility model relates to the technical field of machine art knives, in particular to a sliding self-locking structure. Background Art

[0002] As the use of utility knives increases, in order to adapt to the use scenarios, an adjustment structure that can adjust the position of the utility knife head is provided to adjust the use of the utility knife, such as the new utility knife disclosed in CN213918363U. When adjusting the utility knife, it is usually necessary to unscrew the nut for rotation adjustment, and then restore the nut after adjustment to lock the position. This adjustment method cannot be operated with one hand. When using the utility knife for cutting operations (such as cutting cardboards of different lengths or cutting different positions of cardboard), it is necessary to adjust the position of the utility knife head at any time. The inability to operate with one hand makes the adjustment of the utility knife inconvenient. Therefore, a sliding self-locking structure is designed to solve the above-mentioned problems.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example

[0021] See also Figure 1-5 The present embodiment provides a sliding self-locking structure, including a mounting frame 1, a mounting slot 2 with an opening at the upper end is provided in the mounting frame 1, and the mounting slot 2 is composed of a limit slot 21, an arc slot 22 and a bottom slot 23. Figure 4As shown, the limiting groove 21, the arc groove 22 and the bottom groove 23 are arranged in sequence from top to bottom, and the limiting groove 21 is square, the two sides of the arc groove 22 are wavy, the arc groove 22 is an upper and lower through hole structure, and the arc groove 22 is provided with a clamping groove 221 on both sides.

[0022] The mounting groove 2 is provided with a mounting rod 3, and a ring 7 is fixedly connected to the bottom of the mounting rod 3. The initial position of the ring 7 is located in the arc groove 22. The two sides of the ring 7 are provided with fixing grooves, and an elastic sheet 71 is fixedly connected in the fixing groove. The elastic sheet 71 is fixedly connected to a limit block 72 away from the fixing groove. The limit block 72 is as shown in FIG. Figure 3 As shown, the side away from the elastic sheet 71 is arc-shaped, and the circular ring 7, the elastic sheet 71 and the limit block 72 constitute an adjustment component.

[0023] The initial position of the stopper 72 is located in the slot 221, and is used to fix the ring 7 to prevent the ring 7 from being pushed by the mounting rod 3 and directly falling into the bottom groove 23. The bottom groove 23 provides a space for the mounting rod 3 to press downward. Accordingly, the ring 7 can also be set to a prism or polygonal shape to prevent the ring 7 from directly sliding in the arc groove 22.

[0024] When in use, it is necessary to rotate the mounting rod 3 so that the mounting rod 3 drives the circular ring 7 to rotate, so that the limit blocks 72 on both sides of the circular ring 7 move, and the rotation of the limit blocks 72 will separate from the card slot 221, so that the limit blocks 72 no longer hinder the descent of the circular ring 7, and then press the mounting rod 3 downward to make the mounting rod 3 drive the circular ring 7 to descend, and make the circular ring 7 separate from the arc groove 22 and enter the bottom groove 23, and then push the mounting rod 3 forward or backward to make the mounting rod 3 drive the bottom circular ring 7 to move in the bottom groove 23.

[0025] By providing the elastic sheet 71 and the limit block 72 on both sides of the circular ring 7, the mounting rod 3 and the circular ring 7 cannot be directly lowered into the bottom groove 23 for adjustment, thereby achieving the locking purpose. Moreover, by rotating the mounting rod 3 to drive the limit blocks 72 on both sides of the circular ring 7 to separate from the card slot 221, the self-locking function can be disabled, so that the circular ring 7 can enter the bottom groove 23 for movement adjustment in the front and rear directions. The adjustment is relatively convenient and can be completed without disassembling the structure or components. In addition, the self-locking structure can be provided to prevent sliding after accidental touch.

[0026] In a specific usage scenario, a blade is installed at the bottom of the ring 7 so that the blade is in the bottom groove 23, and an outlet is opened at the rear of the mounting frame 1 so that one end of the blade extends out of the bottom groove 23 for use. When adjusting, the mounting frame 1 can be held and the thumb can be placed on the upper part of the mounting rod 3 and pressed down. While pressing down, a rotational force is applied to rotate the mounting rod 3 around its own center, and the ring 7 drives the blade to adjust according to the above steps. Using this structure for adjustment, the adjustment process can be completed with one hand, and it can be achieved without disassembling any structure, which is very convenient to adjust.

[0027] After the positions of the circular ring 7 and the mounting rod 3 in the mounting frame 1 are adjusted, the circular ring 7 needs to be locked again to achieve the purpose of fixing after adjustment, so that the blade connected to the lower end of the circular ring 7 can be fixed, thereby enabling the blade to be used; therefore, a limiting ring 6 is rotatably connected to the lower part of the mounting rod 3, and the mounting rod 3 passes through the limiting ring 6, the limiting ring 6 is located in the limiting groove 21 and slides, the upper end of the limiting ring 6 is fixedly connected to the spring 5, the upper end of the spring 5 is fixedly connected to the push plate 4, and the push plate 4 is fixedly installed on the upper end of the mounting rod 3.

[0028] When adjusting the blade according to the above steps, the rotation of the mounting rod 3 will drive the push plate 4 to rotate, and the push plate 4 will drive the spring 5 to rotate slightly, and the mounting rod 3 will drop according to the above description. At this time, the position of the limit ring 6 in the limit groove 21 remains unchanged, and the push plate 4 is driven by the mounting rod 3 to drop, and the spring 5 will be squeezed and contracted. After the bottom ring 7 drives the blade to adjust, the mounting rod 3 can be directly released. At this time, the spring 5 is no longer subjected to the force and will stretch and recover. At the same time, the torsion of the spring 5 will also rotate and recover, thereby driving the mounting rod 3 and the ring 7 to rise and rotate and recover, so that after the ring 7 rises and enters the arc groove 22, it drives the limit block 72 to enter the clamping groove 221, and the recovery process is completed.

[0029] The sliding self-locking structure can also be applied to other hand tools such as telescopic saws, which is easy to adjust and has a wide range of applications.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
