Description

Technical Field

[0001] The utility model relates to the technical field of clamps of clamps, in particular to a clamp without a spring structure. Background Art

[0002] A clamp is a simple mechanical device consisting of two clamps with a spring tensioner to control the clamps to open or return to their original shape, and is used to clamp an object.

[0003] In this technology, the spring structure will limit the structural shape and structural technical effect of the clip, and there are also certain process limitations in assembly. For example, the patent number is CN201320233. The rotating shaft of the clothespin connects the middle and upper parts of the left clip and the right clip together, and the spring passes through the upper part of the left clip and the right clip and the two ends are connected at the middle of the left clip and the right clip. Hook holes are provided on the lower part of the left clip and the right clip. With the utility model, the clothespin can be clamped on the clothes drying rod, and then the hook on the clothes drying rack can be passed through the hook hole and firmly hooked to achieve the purpose of windproof, and it can be used to dry various items. However, the elastic force recovery and clamping technical structure based on the spring still has the defects of high manufacturing cost, many parts, and complicated assembly process. Now the market needs to further need a clip that is not only smart and usable, but also overcomes the above technical defects. Summary of the invention

[0004] In order to solve the above problems, the utility model provides a clip without a spring structure, which pioneeringly removes the spring structure of the original clip and instead sets a spring sheet on the inner side of the pressing arm of the clip, thereby greatly reducing the manufacturing cost and improving the production efficiency.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a clip without a spring structure, including a pair of clips and spring sheets arranged in a mirror image, the clip including a clamping head at the upper end, a lever section in the middle, and a clamping handle at the lower end, wherein: a spring sheet groove is arranged on the inner side of the clamping handle, a transverse protrusion is arranged on the lever section, and a through hole is arranged vertically on the transverse protrusion; the spring sheet includes a central section, and skiving pieces extending on both sides of the central section, a positioning block is arranged on the central section, the skiving piece is inserted into the spring sheet groove, the positioning block is inserted into the through hole, the skiving piece of the spring sheet is fixed in the spring sheet groove of the clamping handle, and the central section is fixed to the outside of the lever section by relying on the positioning block, and the clip and the spring sheet are completely combined into an integrated structure.

[0006] By adopting the above-mentioned technical structure, the utility model adopts a completely different structure from the two existing technical structures. It pioneers the use of a U-shaped spring piece, and uses elastic metal or elastic plastic to be pre-set to the required U-shape or V-shape. The U-shape or V-shape can accumulate elastic potential energy in the central section when the user squeezes the clamp handle with the skiving piece pressed to the central axis position. When the user releases the clamp handle, the central section releases the elastic potential energy to restore the shape, and the clamp handle of the clamp expands in an outward-pushing fan-shaped angle, and the clamp heads are merged to clamp objects or close the clamping mouth.

[0007] Preferably, the side of the transverse projection is provided with a side wing upwardly. The front and rear side wing pieces can form a groove structure to protect the internal structure.

[0008] Preferably, the transverse protrusion is provided with a notch, and a gull-wing piece is provided above the transverse protrusion.

[0009] Preferably, the gull-wing piece includes a middle arc piece and an oblique piece, the head end and the tail end of the middle arc piece are provided with the oblique piece, the middle arc piece has a shaped arc in the center, the oblique piece is fixed on the inner wall of the chuck, and the arc is stuck in the notch.

[0010] The use of this structure can further strengthen the clamping force of the clamp after the assembly is completed. In particular, after combining the elastic potential energy of the spring piece, it can have a double-layer elastic structure, and also has the ability to improve the connection strength between the clamping arm and the connecting piece, which is beneficial to relieve and release the elastic tension borne by the tensioning piece when the clamp is opened, and has the ability to limit excessive compression of the spring piece, so that the user will not feel that the spring piece is over-compressed toward the center, which may cause the spring piece to break.

[0011] Preferably, the gull-wing piece includes a head end and a tail end of a middle arc piece, and lower buckles are arranged, and the lower buckles are fixed to the inner wall of the lever section.

[0012] Preferably, the spring piece is in a U-shape or a V-shape and is made of elastic metal or elastic plastic. Elastic metal has the longest service life but is relatively expensive, while elastic plastic is the best material with sufficient elasticity and low cost.

[0013] Preferably, a clamping head is arranged on the top of the clamping head, a pattern is arranged on the inner wall of the clamping head, and a clamping groove is arranged on the outer wall. When the two clamps are clamped together, they can be used for positioning and anti-slip.

[0014] Preferably, the clamp handle is provided with a windproof hole on the outer side of the hole. The windproof hole is used to insert a clothes hanger or a clothes rope to prevent wind.

[0015] The beneficial effects of the present invention are as follows: the spring structure of the original clip is removed in a pioneering way, and a U-shaped spring sheet is provided on the inner side of the pressing arm of the clip instead, so that after the assembly of the clip is completed, the clamping force of the clamp head is further strengthened, especially after the elastic potential energy of the spring sheet is combined, it is also possible to switch to using only one spring sheet, and further switch to the double-layer elastic structure, and add the gull-wing sheet to improve the connection strength between the clamping arm and the connecting piece, which is beneficial to relieve and release the elastic tension borne by the tensioning piece when the clamp is opened, and has the ability to limit excessive compression of the spring sheet, so that the user will not feel that the spring sheet is excessively compressed toward the center, causing the spring sheet to break.
