Abstract
The utility model relates to the concrete pumping field, in particular to a concrete piston sealing member. The concrete piston sealing member comprises a sealing member body, wherein a plurality of bosses are arranged on the outer side surface of the sealing member body. Compared with the prior art, the bosses are arranged on the outer side surface of the sealing member body of the concrete piston sealing member, so that the contact area of the concrete piston sealing member can be reduced, contact friction is reduced, and the service life of the concrete piston sealing member is prolonged.
Description
Technical field
The utility model relates to the concrete pumping field, particularly a kind of concrete piston seal body.
Background technique
Along with the fast development of China's economic construction, being on the increase of construction project, market also increases day by day for the demand of concrete equipment.Concrete pump is a kind ofly to utilize the concrete piston and carry that slipper seal realizes that suction and stock function are transported to concrete the equipment of construction engineering desired location between the cylinder.But there is following defective in present concrete piston seal:
The outer side surface of concrete piston seal body is level and smooth, and contact friction force is bigger during use, causes concrete piston seal body fragile.
The model utility content
The utility model purpose is to provide a kind of concrete piston seal body, is level and smooth with the outer side surface that solves concrete piston seal body of the prior art, and contact friction force is bigger during use, causes the flimsy technical matters of concrete piston seal body.
The utility model purpose is achieved through the following technical solutions:
A kind of concrete piston seal body comprises the seal body, and the outer side surface of described seal body is provided with some boss.
Preferably, the height of described boss is 2.5mm.
Preferably, described boss is disposed on the outer side surface of described seal body.
Preferably, described boss evenly is arranged on the outer side surface of described seal body at interval.
Be filled with aluminium block in the described seal body.
Preferably, described seal body is provided with lip.
Compared with prior art, the utility model has following advantage:
1, concrete piston seal body of the present utility model arranges boss at the outer side surface of seal body, can reduce the area of contact of concrete piston seal body, reducing contact friction force, thereby prolongs working life of concrete piston seal body;
2, be filled with aluminium block in the seal body of the present utility model, can strengthen the shock resistance of concrete piston seal body;
3, the lip of seal body of the present utility model has certain magnitude of interference, can guarantee good sealing effect.
Description of drawings
Fig. 1 is the sectional view of concrete piston seal body of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, describe the utility model in detail.
See also Fig. 1, concrete piston seal body of the present utility model comprises seal body 1, and the outer side surface of seal body 1 is provided with some boss 11.In this example, the height of boss 11 is 2.5mm.Boss evenly is arranged on the outer side surface of seal body 1 at interval.Concrete piston seal body of the present utility model arranges boss at the outer side surface of seal body, can reduce the area of contact of concrete piston seal body, reducing contact friction force, thereby prolongs working life of concrete piston seal body.
Be filled with aluminium block 13 in the seal body of the present utility model, can strengthen the shock resistance of concrete piston seal body.
Also be provided with lip 12 on the seal body of the present utility model.Lip has certain magnitude of interference, can guarantee good sealing effect.
More than disclosed only be several specific embodiments of the application, but the application is not limited thereto, any those skilled in the art can think variation, all should drop in the application's the protection domain.
