[0002] Linear guides, also known as linear rails, slides, linear guides, and linear slides, are used in high-precision or high-speed linear reciprocating motion situations. They can bear a certain torque and can achieve high-precision linear motion under high load conditions.

[0003] In the prior art, when the linear guide rail is in use, the balls inside the linear guide rail will generate friction with the base when rolling, and will impact the base, which will not only damage the guide rail but also generate noise.

[0004] However, traditional linear guides do not have the ability to resist impact, which not only reduces the service life of the guides, but also causes workers to be in a noisy environment for a long time, which can easily cause damage to their bodies, making the cost of using linear guides relatively high.

[0024] In order to make the purpose and technical solution of the utility model clearly and completely described, and the advantages more clearly understood, the embodiments of the utility model are further described in detail in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of 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.

[0025] Embodiment 1

[0026] See also Figure 1-Figure 7 The utility model provides a technical solution: a vibration reduction and noise reduction mechanism for a linear guide rail, comprising a base 1 and two bodies 2, a shock-absorbing block 3 is installed between the base 1 and the body 2, the shock-absorbing block 3 is made of polyethylene, has good shock-absorbing and energy-absorbing performance, and can be customized according to needs, one side of the shock-absorbing block 3 is in contact with the outside of the base 1, and the other side of the shock-absorbing block 3 is in contact with the inner side of the body 2, so that when the slider slides, the shock-absorbing block 3 can directly buffer the impact force, and a plurality of rubber blocks 4 are fixedly connected to the inside of the shock-absorbing block 3. Since the rubber block 4 is made of rubber material, the rubber block 4 can be elastically deformed, so that the rubber block 4 can absorb the impact force, and the rubber block 4 is designed in a "V" shape, so that the rubber block 4 can be deformed quickly, so that the rubber block 4 can fully absorb the impact force, and the plurality of rubber blocks 4 are connected to each other, and the plurality of rubber blocks 4 are used together, so that the impact force can be stably and comprehensively absorbed.

[0027] When the slider slides outside the base 1 and the body 2, the impact force generated by the ball and the body 2 can be directly transmitted to the shock absorbing block 3, so that the shock absorbing block 3 can transmit the impact force to the rubber block 4. By utilizing the elastic potential energy of the rubber block 4, the impact force can be absorbed, so that the impact force will not cause damage to the base 1, thereby ensuring that the service life of the base 1 is not reduced. In addition, since the rubber block 4 absorbs the impact force, the noise can be reduced, thereby improving the working environment of the workers and reducing the labor cost.

[0028] Embodiment 2

[0029] On the basis of Example 1, in order to achieve enhanced vibration reduction capability, a plurality of sleeves 5 are fixedly installed on the inner wall of the shock absorbing block 3. The sleeve 5 is of oblique design, and every two sleeves 5 are of symmetrical design, so that the impact force can be directly transmitted to the inside of the sleeve 5. A slide groove 6 is provided inside the sleeve 5, and a spring 7 is fixedly connected to the inner wall of the slide groove 6. By utilizing the elastic potential energy of the spring 7, the impact force can be further buffered, so that the vibration reduction and noise reduction capability can be improved. The other end of the spring 7 is fixedly connected to a limiting block 8, and the end of the limiting block 8 away from the spring 7 is fixedly connected to a push rod 9, and the other end of the push rod 9 is fixedly connected to the outside of the rubber block 4, so that the rubber block 4 can transmit the remaining impact force to the spring 7 through the push rod 9, and the outside of the push rod 9 is slidably connected to the inside of the slide groove 6, so that the push rod 9 can slide smoothly inside the slide groove 6, so that the push rod 9 will not deviate when squeezing the spring 7.

[0030] When the rubber block 4 fails to completely absorb the impact force, the impact force will push the push rod 9 to move in the direction of the spring 7, so that the push rod 9 can squeeze the spring 7 through the limit block 8 to produce deformation, so that the spring 7 can perform a reset movement, so that the reaction force generated by it can offset the impact force, so that the impact force will not affect the base 1. By using the rubber block 4 and the spring 7 to offset the impact force, the vibration reduction effect is greatly improved and the noise is further reduced.

[0031] Embodiment 3

[0032] On the basis of the second embodiment, in order to achieve stable installation of the shock-absorbing block 3, the adjacent sides of the two bodies 2 are fixedly connected with a connecting block 12, and the connecting block 12 is designed in a "C" shape, so that the connecting block 12 can be completely fitted with the base 1, so that the connection block 12 is placed more stably, and the outside of the connecting block 12 is slidably connected to the inside of the base 1, and the front end of the connecting block 12 is movably connected with a bolt 13, and the outside of the bolt 13 is connected to the internal thread of the base 1, so that the bolt 13 can penetrate the bolt 13 and be connected to the inside of the base 1.

[0033] By sliding the shock-absorbing block 3 with the connecting block 12 installed into the interior of the base 1, the inner side of the "C" shape of the connecting block 12 can fit with the front end of the base 1, and then the bolts 13 are screwed into the connecting block 12 and the interior of the base 1, so that the position of the connecting block 12 can be fixed, and then the position of the shock-absorbing block 3 can be fixed, so that the shock-absorbing block 3 can be easily installed.

[0034] Embodiment 4

[0035] On the basis of Example 3, in order to further limit the shock-absorbing block 3, four mother belts 10 are fixedly connected to the outside of the base 1, and sub-belts 11 are fixedly connected to the upper and lower sides of the body 2. The sub-belts 11 on both sides of the upper side are symmetrically designed, and the mother belts 10 and the sub-belts 11 are matched, and the mother belts 10 and the sub-belts 11 are bonded together.

[0036] After the shock absorbing block 3 is installed on the outside of the base 1, the inner side of the body 2 is fitted with the outer side of the shock absorbing block 3. At this time, the sub-belt 11 is adhered to the main belt 10, so that the body 2 can be stably installed on the outside of the base 1, and the body 2 can limit the shock absorbing block 3, so that the shock absorbing block 3 will not easily shift from between the base 1 and the body 2 after receiving the impact.

[0037] In actual use, when the slider slides, it will impact the body 2, and then the body 2 will transfer the impact force to the shock-absorbing block 3, so that the shock-absorbing block 3 can transfer the impact force to the rubber block 4. Since the rubber block 4 is a "V"-shaped design, the impact force will squeeze and deform the rubber block 4, so that the rubber block 4 can perform a reset movement, and then the reaction force formed by the rubber block 4 can offset the impact force, thereby greatly reducing the impact of the impact force on the base 1, and due to the reduction of the impact force, the noise between the ball and the base 1 is also reduced, thereby making the working environment of the workers better, thereby reducing the employment cost.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
