[0026] 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.

[0027] The utility model provides Figure 1-5 A metallurgical valve handle shown in the figure includes a handle body 1 and a connecting rod 2, the connecting rod 2 is symmetrically fixedly arranged inside the handle body 1, and a protective structure 3 is arranged outside the connecting rod 2, and the protective structure 3 includes a first protective pad 301 and a second protective pad 302, the first protective pad 301 is wrapped around the outer wall of the connecting rod 2, the first protective pad 301 is used for operational protection of the connecting rod 2, the second protective pad 302 is fixedly arranged inside the first protective pad 301, and a rolling component for movement is arranged on the second protective pad 302. The arrangement of the first protective pad 301 and the second protective pad 302 enables the connecting rod 2 to have protective performance during operation, and the first protective pad 301 and the second protective pad 302 are both elastic structures, so that when the operator rotates the handle body 1 and the connecting rod 2, when the hand is between the connecting rod 2 and a force is applied, it can prevent the operator's hand from colliding with the connecting rod 2 directly contacts and squeezes the outer wall of the operator's hand, thereby preventing the operator's hand from being directly squeezed by the connecting rod 2 and producing an indentation, so that the setting of the first protection pad 301 can separate the operator's hand and the connecting rod 2, so that the operator's hand can squeeze the first protection pad 301, and then the elastic deformation of the first protection pad 301 can be used to reduce the squeezing force on the operator's hand. At the same time, the second protection pad 302 is fixedly arranged inside the first protection pad 301, increasing the distance between the first protection pad 301 and the connecting rod 2, improving the performance of buffering the squeezing force of the operator's hand, and a rolling component is fixedly arranged on the inner wall of the second protection pad 302. Through the cooperation of the rolling component, the first protection pad 301 and the second protection pad 302 can be flexibly moved in position to adapt to the movement of the hand, thereby improving the range and effect of safety protection for the operator's hand;

[0028] Furthermore, the rolling assembly includes a mounting groove 305 and a ball 303. The mounting groove 305 is provided on the inner wall of the second protective pad 302. The mounting groove 305 is arranged in an arc shape. The ball 303 is rotatably arranged in the inner cavity of the mounting groove 305. The mounting groove 305 is used for the movement of the second protective pad 302 on the outer wall of the connecting rod 2. The diameter of the mounting groove 305 is smaller than the diameter of the ball 303 exposed by the volume of the second protective pad 302, so that the ball 303 can flexibly rotate in the inner cavity of the mounting groove 305 while avoiding falling off from the inner cavity of the mounting groove 305. The arrangement of the ball 303 can be located on the outer wall of the connecting rod 2 while the second protective pad 302 is installed on the outer wall of the connecting rod 2, and the ball 303 can make the second protective pad 3 02 moves on the connecting rod 2, so that the second protective pad 302 is adapted to multiple operating ranges, and at the same time, the distance between the second protective pad 302 and the connecting rod 2 can be increased, the elastic deformation range of the second protective pad 302 can be increased, and the elastic effect of the second protective pad 302 can be improved. At the same time, the moving ball 303 and the second protective pad 302 can cause friction between the ball 303 and the connecting rod 2, so that the ball 303 moves along the outer wall of the connecting rod 2, avoiding the outer wall of the connecting rod 2 from being rusted due to dust or other debris. The moving second protective pad 302 and the ball 303 can make the dust or debris fall off the connecting rod 2, thereby extending the service life of the connecting rod 2 and reducing the use cost of the connecting rod 2 and the handle body 1;

[0029] Furthermore, the protective structure 3 also includes a buffer layer 304, which is fixedly arranged between the first protective pad 301 and the second protective pad 302. The buffer layer 304 is used to enhance the deformation degree of the first protective pad 301 and the second protective pad 302. The inner cavity of the buffer layer 304 is provided with a plurality of through holes, and the plurality of through holes form a honeycomb shape. The provision of the buffer layer 304 increases the space between the first protective pad 301 and the second protective pad 302, enhances the elastic deformation degree of the first protective pad 301 and the second protective pad 302, thereby improving the buffering performance of the first protective pad 301 and the second protective pad 302. At the same time, the through holes provided on the outer wall of the buffer layer 304 form a honeycomb shape, which provides space for the deformation of the buffer layer 304, enhances the air permeability of the first protective pad 301 and the second protective pad 302, and improves the comfort of use of the first protective pad 301 and the second protective pad 302.

[0030] Finally, the first protection pad 301 and the second protection pad 302 are both made of any one of elastic rubber or elastic silicone. A fixing structure 4 is arranged between the first protection pad 301 and the second protection pad 302. The fixing structure 4 includes a fixing layer 401 and a protective layer 402. The fixing layer 401 is fixedly arranged on the outer wall of the first protection pad 301. The fixing layer 401 is used to limit the shape of the first protection pad 301 on the connecting rod 2. The protective layer 402 is adhered to the outer wall of the fixing layer 401. The protective layer 402 is used to limit the adhesion of the fixing layer 401. The fixing layer 401 is a tearable adhesive, and the protective layer 402 is a release paper. When the first protection pad 301 is not in use, the protective layer 402 can block the fixing layer 401, thereby preventing the fixing layer 401 from being damaged. The fixing layer 401 can adhere to the first protective pad 301, thereby avoiding affecting the adhesion effect of the fixing layer 401, and the fixing layer 401 is fixedly arranged on the outer wall of the first protective pad 301, so that when the first protective pad 301 is wound along the outer wall of the connecting rod 2, the end of the first protective pad 301 where the fixing layer 401 is not arranged can be rolled up to the inside of the end of the first protective pad 301 where the fixing layer 401 is arranged, so that after the protective layer 402 is torn off, the exposed fixing layer 401 can adhere to the outer wall of the first protective pad 301, thereby stabilizing the rolled state of the first protective pad 301, and further making the first protective pad 301 relatively stable on the outer wall of the connecting rod 2, effectively improving the stability of the position installation of the first protective pad 301, and further enhancing the practicality of the protective structure 3.
