Life, and then the service life of backstop skeleton can be extended.
Further, it is provided with vibration damping cavity in the damping ring.
By using above-mentioned technical proposal, vibration damping cavity is set in damping ring, the vibration reduction and cushioning of damping ring can be improved
Can, and then the service life of backstop skeleton can be extended.
Further, the damping ring is set as being detachably connected with support plate.
By using above-mentioned technical proposal, damping ring is set as being detachably connected with support plate, can facilitate to damping ring into
Row installation and replacement, and then the service life of backstop skeleton can be extended.
Further, damping ring inner wall protrusion is provided with several limited posts, the support plate outer wall depression be provided with
The limiting slot of limited post cooperation.
By using above-mentioned technical proposal, limited post can prevent damping ring from occurring to turn relative to support plate with limiting slot cooperation
It is dynamic, the stability that damping ring is connect with support plate can be improved.
Further, the limiting slot is dovetail groove.
By using above-mentioned technical proposal, limiting slot is dovetail groove, then limited post can prevent vibration damping with limiting slot cooperation
Ring rotates relative to support plate, can improve the stability that damping ring is connect with support plate.
Further, the chamfered setting of the seamed edge of the support plate.
By using above-mentioned technical proposal, on the one hand the chamfered setting of seamed edge of support plate can facilitate and pacify damping ring
It is attached on support plate, on the other hand can remove the burr generated at seamed edge in process, prevent burr from influencing backstop skeleton
Assembly precision, and then the stability of backstop skeleton can be improved.
Further, the chamfered setting of the seamed edge of the bottom plate.
By using above-mentioned technical proposal, the chamfered setting of seamed edge of bottom plate can remove in process in seamed edge
Locate the burr generated, prevents burr from influencing the assembly precision of backstop skeleton, and then the stability of backstop skeleton can be improved.
Further, the surface roughness of the support plate outer wall is not more than 0.8.
By using above-mentioned technical proposal, the surface roughness of support plate outer wall is not more than 0.8, can make damping ring and support plate
It fits closely, and then damping ring and support plate connective stability can be improved.
Further, the damping ring is rubber ring.
By using above-mentioned technical proposal, damping ring is rubber ring, has good elastic deformation ability, can play and subtract
It shakes cushioning effect, and then the service life of backstop skeleton can be extended.
In conclusion the utility model has the advantages that：
1, it uses bottom plate and support plate is integrally formed, to generate the effect for extending backstop skeleton service life；
2, it is arranged with damping ring on support plate, support plate can be avoided to be in direct contact with other parts, that is, avoid support plate and its
The rigid collision of its parts plays the role of vibration reduction and cushioning, then can extend the service life of support plate, and then can extend backstop
The service life of skeleton；
3, the chamfered setting of the seamed edge of bottom plate and support plate can remove the burr generated at seamed edge in process,
It prevents burr from influencing the assembly precision of backstop skeleton, and then the stability of backstop skeleton can be improved.

Specific implementation mode
The utility model is described in further detail below in conjunction with attached drawing.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can as needed make the present embodiment the modification of not creative contribution after reading this specification, but
As long as all being protected by Patent Law in the right of the utility model.
Embodiment：
A kind of backstop skeleton is vertically connected with support plate 5 in a ring, this reality as shown in figure 3, including bottom plate 4 on bottom plate 4
It applies a bottom plate 4 to overlap with the center line of support plate 5, and is integrated casting and forming.
As shown in figure 3, the chamfered setting of seamed edge of bottom plate 4 and support plate 5, the present embodiment bottom plate 4 are connect with support plate 5
