[0002] Nitrogen spring is a new type of elastic component using high-pressure nitrogen as the working medium. It is small in size, has high elastic force, long stroke, stable operation, precision manufacturing, long service life (one million times), flat elastic curve, and does not require pre-tightening, etc. It has the functions that conventional elastic components such as metal springs, rubber and air cushions cannot complete, simplifying mold design and manufacturing, facilitating mold installation and adjustment, extending the service life of the mold, and ensuring stable product quality.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figures 1 to 3 , the utility model provides a technical solution:

[0019] A nitrogen spring protection device comprises a first sleeve 1, a second sleeve 2 arranged outside the first sleeve 1, and a nitrogen spring 3 placed in the first sleeve 1. An adjustment component is installed between the outer wall of the first sleeve 1 and the inner wall of the second sleeve 2 for adjusting the position of the second sleeve 2. A mounting seat 4 is provided at the bottom of the first sleeve 1. A fixing groove is provided in the middle of the mounting seat 4 for fixedly placing the nitrogen spring 3. A fixing cylinder 5 is fixedly installed in the middle of the second sleeve 2. A limiting column 6 is provided inside the fixing cylinder 5 for sliding connection. A limiting cavity 7 is provided below the limiting column 6. A buffer component is symmetrically provided between the bottom end and the fixing cylinder 5 for slowing down and offsetting the kinetic energy generated by external collision.

[0020] During use, the position of the second sleeve 2 can be adjusted by adjusting the assembly, so that the second sleeve is separated from the first sleeve, so that the protective device can be opened, and then the nitrogen spring is placed in the first sleeve 1, so that it is placed in the fixing groove on the mounting seat 4 for limit, and the position of the second sleeve 2 is adjusted again, so that the second sleeve 2 is close to the nitrogen spring 3, thereby achieving the purpose of protecting the nitrogen spring 3 and avoiding damage caused by collision between the nitrogen springs 3 during transportation. At the same time, the fixing cylinder 5 and the limiting column 6 are driven to move toward the nitrogen spring 3, so that the end of the nitrogen spring 3 enters the limiting cavity 7 below the limiting column 6, thereby protecting the end of the nitrogen spring 3. By setting a buffer assembly, when the upper end of the nitrogen spring 3 is collided, the limiting column 6 will be squeezed to slide in the fixing cylinder 5, and at the same time, the buffer assembly will be squeezed to jointly slow down and offset the kinetic energy generated by the external collision, thereby having a buffering protection effect on the end of the nitrogen spring.

[0021] The adjustment assembly includes a threaded rod 8 symmetrically mounted on the outer wall of the first sleeve 1 and a nut 9 sleeved on the outside of the threaded rod 8. The threaded rod 8 and the nut 9 are spirally connected. One side of the nut 9 is fixedly connected to the inner wall of the second sleeve 2. The threaded rod 8 can be rotated forward and backward to drive the nut 9 to perform reciprocating linear motion on the threaded rod 8, thereby adjusting the second sleeve 2 and the first sleeve 1, so that nitrogen springs 3 of different heights can be used, thereby improving the versatility of use.

[0022] A plurality of first springs 10 are installed at equal intervals on the inner wall of the fixing groove. A clamping block 11 is connected to one end of the first spring 10 away from the inner wall of the fixing groove. The elastic force of the first spring 10 cooperates with the clamping block 11 to limit the position of the nitrogen spring 3.

[0023] The outer side of the limiting column 6 is symmetrically provided with a limiting slider 12, and the inner side of the fixed cylinder 5 is provided with a limiting groove matching the limiting slider. The limiting slider 12 is slidably connected to the limiting groove, which improves the sliding stability of the limiting column 6.

[0024] The buffer assembly includes a telescopic rod 13 installed between the limiting column 6 and the fixed cylinder 5, and a second spring 14 sleeved on the outside of the telescopic rod 13. One end of the second spring 14 is connected to the limiting column 6, and the other end is connected to the fixed cylinder 5. When the limiting column 6 is collided, it will squeeze the telescopic rod 13 and the second spring 14. With the cooperation of the telescopic rod 13 and the second spring 14, a multiple buffering effect is achieved to protect the end of the nitrogen spring 3.
