Description

Technical Field

[0001] The utility model relates to the technical field of protective equipment, in particular to a protective cover for preventing hands from being injured by being hit. Background Art

[0002] At present, hammers and other tools are needed in many work and life scenarios. For example, chisels, striking sleeves, and striking screwdrivers require hammers for striking. During the striking process, people need to hold and support the chisels, striking sleeves and other intermediate media in order to strike. However, due to the small contact area at the ends of the intermediate media such as chisels and striking sleeves, during the striking process, the hammer or hammer is prone to alignment deviation with the intermediate media such as chisels, resulting in crooked striking. The hand holding the intermediate medium is very likely to be injured, posing a great safety hazard. Utility Model Content

[0003] The utility model aims to provide a protective cover for preventing hands from being injured, so as to solve the problem in the prior art that a hammer is easily tilted during use, thus causing injuries to hands.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical solution: a protective cover for preventing hands from being injured by falling, comprising a locking sleeve and a protective cover body located below the locking sleeve, the internal hollow structure between the locking sleeve and the protective cover body being connected, the protective cover body being in the shape of a trumpet that gradually becomes larger from top to bottom, and the lower end of the protective cover body being provided with an anti-slip structure.

[0005] The principles and advantages of this solution are:

[0006] In actual application, the locking sleeve and the protective cover body of the present scheme are mounted on intermediate media such as chisels and striking sleeves, and the user's hands hold and fix the intermediate media such as chisels and striking sleeves in the protective cover body. During the process of using a hammer to strike, when the hammer is knocked crooked, it falls on the protective cover body. The protective cover body has a certain resistance strength to protect the hands, avoiding injuries to the hands, and greatly reducing the safety hazards during the use of the hammer; secondly, in the present scheme, the lower end of the protective cover body is provided with an anti-slip structure. When the hammer slides, the anti-slip structure can effectively stop the hammer from continuing to fall, thereby preventing other injuries to the body caused by the hammer.

[0007] Furthermore, the locking sleeve is provided with an adjustment opening, and locking plates protruding from the locking sleeve are provided at both ends of the adjustment opening, and a connecting and fixing structure for locking the two locking plates is provided on the locking plates.

[0008] The design of the above-mentioned adjustment opening makes the internal size of the locking sleeve adjustable, the size range of the intermediate medium that can be accommodated is wider, and the protective cover has a wider range of use; and compared with the time and effort required to put an integrated complete locking sleeve on or remove the intermediate medium, the adjustment opening on the locking sleeve and the provision of a locking plate and a connecting and fixing structure at the adjustment opening realize simple and quick disassembly and assembly of the locking sleeve.

[0009] Furthermore, the anti-slip structure is a curled edge that is rolled up at the lower end of the protective cover body, and a layer of rubber edging is wrapped on the curled edge.

[0010] The above-mentioned arrangement is performed on the lower end of the protective cover body to form a groove at the lower end of the protective cover body. The rolled edge and the groove structure can effectively intercept the hammer in the process of sliding. At the same time, the rubber edging on the rolled edge has a large friction force, which can further prevent the hammer from continuing to fall and avoid causing damage to the hands or other body parts of the user.

[0011] Furthermore, the anti-slip structure is an anti-slip ring sleeved on the lower end of the protective cover body, and the anti-slip ring is a rubber ring.

[0012] The anti-slip ring is protruding from the surface of the protective cover body and is made of rubber material. There is a large friction between the anti-slip ring and the hammer, which can effectively prevent the hammer from continuing to slide and protect the hands and body of the user.

[0013] Furthermore, the connection and fixing structure is a snap-fit ​​structure, which includes protrusions and buckles respectively arranged on different locking sheets.

[0014] In the above arrangement, the two locking plates can be simply and quickly fixed and removed by using the protrusions and the buckle fit.

[0015] Furthermore, the connecting and fixing structure is a rotary locking structure, which includes a locking piece and a locking groove arranged on any locking plate, and a threaded hole is opened on the other locking plate. The locking piece includes a rotating rod threadedly connected to the locking plate and a locking block evenly distributed circumferentially at the end of the rotating rod. The locking groove includes a plurality of mounting openings in an annular array on the surface of the locking plate and a plurality of arc grooves inside. The mounting openings correspond to the arc grooves one by one and are connected.

[0016] In the above setting, the locking block at the end of the rotating rod enters the arc groove along the installation opening, and then the rotating rod is rotated to make the locking block move away from the installation opening and be fixed inside the locking plate. At the same time, rotating in the opposite direction can make the locking block disengage from the locking groove, which can realize simple and quick locking and unlocking; secondly, the rotating rod is threadedly connected to another locking plate so that it can be adjusted and fixed according to the size of the intermediate medium, which is more practical.

[0017] Furthermore, the connection and fixing structure is a bolt structure, which includes a fastening bolt and a nut, and a mounting hole for the fastening bolt to pass through is opened on the locking plate.

[0018] In the above arrangement, the locking sleeve is pressed against the intermediate medium such as the chisel by tightening the bolts and nuts, thereby increasing the size range of the intermediate medium that can be accommodated in the locking sleeve. Compared with the snap-fit ​​structure, the bolt fixation makes the connection between the intermediate medium and the locking sleeve more stable.

[0019] Furthermore, the protective cover body is made of high-strength plastic.

[0020] The high-strength plastic material makes the protective cover body have sufficient strength and rigidity, which can frequently withstand the force of the hammer hitting the protective cover without being damaged quickly, thus playing a role in protecting the hands of the user.

[0021] Furthermore, the protective cover body is transparent.

[0022] The above arrangement enables the user to see clearly whether the lower end of the intermediate medium such as the chisel is in the correct position while using the protective cover body for protection, and make timely adjustments to avoid the need to confirm whether the position to be struck is accurate from the lower end of the protective cover due to obstruction of vision.

[0023] Furthermore, a notch for accommodating an arm is provided at the lower end of the protective cover body.

[0024] The above arrangement allows the hand wall of the user to fit in with the lower end of the protective cover, which provides better protection for the user's hands, while also clamping the protective cover on the arm to prevent it from shaking. BRIEF DESCRIPTION OF THE DRAWINGS
