The housing of the breaker hammer is an important part of the breaker hammer, which mainly protects the breaker hammer movement. The liner plate is needed to connect the breaker hammer movement and the breaker hammer housing. The liner plate is located at the front end of the breaker hammer movement.

[0003] Most of the breaker hammer shells on the market are not equipped with a buffer structure, which makes it very easy to be damaged due to wear during use, greatly reducing the service life of the breaker hammer shell. In addition, the existing breaker hammer shell lining plate has low strength. When subjected to the impact of the breaker hammer's large impact force, the lining plate is prone to breakage, causing the movement and the piston to deviate during operation. Utility Model Content

DETAILED DESCRIPTION

[0021] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.

[0022] According to one aspect of the present invention, Figure 1-5 As shown, a breaker housing structure for improving the strength of the inner lining plate is provided, comprising a front housing 1 and a rear housing 2, a connecting rod 3 is symmetrically fixedly connected to the left side of the rear surface of the front housing 1 and the left side of the front surface of the rear housing 2, a fixed connecting plate 4 is fixedly connected to the rear surface of the front housing 1 and the front surface of the rear housing 2 and located on the right side of the two connecting rods 3, a through-type middle hole 5 is opened on the rear surface of the front housing 1 and the front surface of the rear housing 2, and a plurality of threaded holes 6 are opened on the rear surface of the front housing 1 and the front surface of the rear housing 2 and located on both sides of the two middle holes 5;

[0023] When the utility model is used, the front shell 1 and the rear shell 2 are fixed as a whole through the set fixed connecting plate 4, and then the breaker is installed and fixed between the front shell 1 and the rear shell 2 through the set multiple threaded holes 6, so as to facilitate the disassembly of the breaker for subsequent maintenance. At the same time, the front shell 1 and the rear shell 2 can be better fixed through the two set connecting rods 3.

[0024] In the present embodiment, a buffer cavity 7 is provided inside the front shell 1 and inside the rear shell 2, and the left and right sides of the two buffer cavities 7 are fixedly connected with a limit rod 8, and the outer walls of the two limit rods 8 are slidably connected with a sliding block 9, and the opposite sides of the two buffer cavities 7 are provided with a through-type sliding groove 10, and the opposite sides of the two sliding blocks 9 extend to the front of the two buffer cavities 7 and are fixedly connected with an inner lining plate body 11, and the outer walls of the two limit rods 8 and the two sides of the two sliding blocks 9 are sleeved with a buffer spring 12, and the two ends of the multiple buffer springs 12 are respectively fixedly connected to the two sides of the two sliding blocks 9 and between the two buffer cavities 7, and the front surfaces of the two inner lining plate bodies 11 are fixedly connected with a plurality of sliding rods 13, and the outer walls of the multiple sliding rods 13 are slidably connected with a buffer plate 14, and the opposite sides of the two buffer plates 14 are fixedly connected with a plurality of buffer springs 2 15 between the two inner lining plate bodies 11, and the opposite ends of the multiple sliding rods 13 are fixedly connected with a limited circular plate 16;

[0025] When the utility model is used, when the breaker is fixedly installed between the front shell body 1 and the rear shell body 2, due to the low strength of the existing inner lining plate body 11, it is easy to cause the inner lining plate body 11 to break when subjected to the impact of the larger impact force of the breaker, thereby causing the movement and the piston to deviate during operation. The two buffer plates 14 are arranged to fit with the two sides of the breaker, so the wear of the two inner lining plate bodies 11 can be effectively reduced by the multiple buffer springs 15 when the breaker vibrates, thereby increasing the service life of the two inner lining plate bodies 11, that is, reducing the damage to the front shell body 1 and the rear shell body 2 caused by the vibration, thereby increasing the overall service life of the equipment, and at the same time, the two sliding blocks 9 and the multiple buffer springs 12 can reduce the vertical force generated by the vibration of the breaker, thereby reducing the damage to the front shell body 1 and the rear shell body 2 caused by the vibration.

[0026] In this embodiment, a plurality of buffer cylinders 17 are fixedly connected to the opposite sides of the two buffer plates 14, a sliding circular plate 18 is slidably connected to the interior of the plurality of buffer cylinders 17, a connecting rod 2 19 is fixedly connected between the plurality of sliding circular plates 18, and a buffer spring 3 20 is fixedly connected between the opposite sides of the plurality of sliding circular plates 18 and the plurality of buffer cylinders 17;

[0027] When the utility model is in use, multiple buffer cylinders 17 are arranged above and below the breaker to effectively support and limit. When the breaker is in use, the multiple buffer springs 15 and two buffer plates 14 are arranged to reduce the lateral force generated by the vibration of the breaker. When the two buffer plates 14 are squeezed and slide back to back, the two buffer plates 14 move back to back through the multiple buffer cylinders 17, so that the multiple sliding circular plates 18 and multiple buffer springs 20 can better decompose the lateral force generated by the vibration of the breaker, thereby reducing the wear of the two inner lining plate bodies 11, thereby improving the strength of the two inner lining plate bodies 11.

[0028] In this embodiment, a protective plate 21 is fixedly connected to the right side of the front shell 1 and the right side of the rear shell 2, a side reinforcement plate 22 is fixedly connected to the left side of the two protective plates 21 and on both sides of the front shell 1 and the rear shell 2, and a protective bottom plate 23 is fixedly connected to the lower surface of the front shell 1 and the lower surface of the rear shell 2. The front shell 1 and the rear shell 2 can be better protected by the two protective plates 21 and the two protective bottom plates 23, and the connection between the two protective plates 21 and the front shell 1 and the rear shell 2 can be reinforced by the multiple side reinforcement plates 22.

[0029] In this embodiment, the front surface of the front shell 1 and the rear surface of the rear shell 2 are fixedly connected with multiple reinforcing ribs 24. The multiple reinforcing ribs 24 can effectively prevent the breaker from being subjected to a large impact force that causes the front shell 1 and the rear shell 2 to deform, thereby causing economic losses.

[0030] In this embodiment, the front surface of the front shell 1 and the rear surface of the rear shell 2 and the front and rear of the two connecting rods 3 are fixedly connected with reinforcing plates 25 by bolts. The two reinforcing plates 25 can reinforce and improve the strength of the front shell 1 and the rear shell 2.

[0031] The working principle of the device is: when the utility model is used, when the breaker is fixedly installed between the front shell body 1 and the rear shell body 2, due to the low strength of the existing inner lining plate body 11, it is easy to cause the inner lining plate body 11 to break when it is subjected to the impact of the larger impact force of the breaker, thereby causing the movement and the piston to deviate during operation. The two buffer plates 14 are arranged to fit with the two sides of the breaker, so the wear of the two inner lining plate bodies 11 can be effectively reduced by the multiple buffer springs 15 when the breaker vibrates, thereby increasing the service life of the two inner lining plate bodies 11, that is, reducing the damage to the front shell body 1 and the rear shell body 2 caused by the vibration, thereby increasing the overall service life of the equipment, and at the same time, the two sliding blocks 9 and the multiple buffer springs 12 can reduce the vertical force generated by the vibration of the breaker, thereby reducing the damage caused by the vibration to the front shell body 1 and the rear shell body 2.
