Description

Technical Field

[0001] The utility model relates to the technical field of ejection hooks, in particular to an ejection hook which can prevent falling off. Background Art

[0002] Injection hook is a special high-end Velcro, a commonly used connecting auxiliary material, which only has hook surface, and the fleece surface can be selected separately. The most common Velcro in our lives is mainly used on clothes, shoes and hats. With the advancement of technology, the Velcro hook surface is gradually replaced by injection hook;

[0003] However, most of the existing injection hooks are fixed on one side of the fabric, and the fleece surface matched with the injection hook is also installed at a fixed position. The fabric is connected by the injection hook and the fleece surface, and the length of the fabric can be adjusted by adjusting the length of the injection hook and the fleece surface. When the length of the injection hook and the fleece surface is short, the stability of the injection hook and the fleece surface is low, and it is easy to fall off.

[0004] In order to solve the above problems, the present application proposes a shooting hook which can prevent falling off. Utility Model Content

[0005] The utility model aims to provide a shooting hook which can prevent falling off, and is mainly used to solve the problem that when the sticking length of the existing shooting hook to the rough surface is short, the sticking stability of the shooting hook to the rough surface is low and the shooting hook is easy to fall off.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0007] A shooting hook capable of preventing falling off comprises a base band, a cavity is provided inside the base band, one end of the base band close to the cavity opening is fixedly connected to a fixed block, an extension band is slidably connected inside the cavity, one end of the extension band extends out of the base band, and the end of the extension band extending out of the base band passes through the fixed block and is slidably connected to the fixed block, a square groove is provided at the bottom of the fixed block, a pressure block is slidably connected inside the square groove, a threaded rod is rotatably connected at the center of the top of the pressure block, the upper end of the threaded rod passes through the fixed block and is threadedly connected to the fixed block, and one end of the threaded rod extending out of the fixed block is fixedly connected to a knob, and a limiting component for fixing the knob is provided on the top of the fixed block.

[0008] The working principle and beneficial effects of the utility model:

[0009] 1. Working principle: The bottom of the base belt and the extension belt are fixedly connected with an ejection hook. When in use, the ejection hook at the bottom of the base belt can be adhered to the fleece surface of the fabric. When it is necessary to adjust the length of the ejection hook and the fleece surface, the extension belt can be pulled to adjust its length and the ejection hook at the bottom can be adhered to the fleece surface, so that the ejection hook and the fleece surface can always maintain a longer adhesion length, and then the knob is turned to drive the pressing block to move downward through the threaded rod to clamp the extension belt, and then the knob is fixed by the limit assembly, which can better fix the extension belt.

[0010] 2. Beneficial effects: A cavity is provided inside the base belt, and an extension belt is slidably connected inside the cavity, so that the length of adhesion between the shooting hook and the rough surface can be adjusted, so that the shooting hook and the rough surface can always maintain a long adhesion length, which can effectively prevent the shooting hook from falling off. Through the fixed block provided at one end of the base belt, people can turn the knob to move the pressure block downward and clamp the extension belt, thereby further improving the stability of the shooting hook when in use.

[0011] When the length of the extension belt needs to be adjusted, the limit block is also pulled in the direction away from the knob. Rotating the knob in the opposite direction can make the pressure block move away from the extension belt, and then the length of the extension belt can be adjusted.

[0012] Preferably, an elastic band is fixedly connected to one side of the inner wall of the cavity away from the fixed block, and the other end of the elastic band is fixedly connected to the extension band. The elastic band arranged inside the cavity can not only effectively prevent the extension band from separating from the base band, but also ensure that when people do not need to use the extension band, the extension band will automatically shrink under the action of the elastic band, thereby making the use of the shooting hook more convenient.

[0013] Preferably, a pull block is fixedly connected to the end of the extension strap away from the base strap, and the thickness of the pull block is not less than the thickness of the extension strap. By setting the pull block at one end of the extension strap, people can pull the extension strap more easily by pulling the pull block, thereby making it more convenient to adjust the length of the extension strap. By setting the thickness of the pull block to be not less than the thickness of the extension strap, the extension strap can be effectively prevented from passing through the fixed block and entering the cavity.

[0014] Preferably, the top and bottom of the pull block are fixedly connected with a plurality of protrusions, and the protrusions are evenly distributed on the pull block in an array. The plurality of protrusions provided on the pull block can effectively increase the friction between people's hands and the pull block, thereby effectively preventing people's hands from slipping when pulling the pull block.

[0015] Preferably, the outer wall of the knob is provided with a rubber sleeve, and the rubber sleeve is provided with anti-slip grooves. The rubber sleeve provided on the outer wall of the knob can make people's hands more comfortable when holding the knob, and the anti-slip grooves provided on the rubber sleeve can increase the friction between people's hands and the knob, thereby effectively preventing people's hands from slipping when turning the knob.

[0016] Preferably, the corners at the bottom of the limiting groove are all chamfered. By setting the corners at the bottom of the limiting groove as chamfers, it is easier for the limiting block to be inserted into the limiting groove. BRIEF DESCRIPTION OF THE DRAWINGS
