The service life of the locking cylinder is prolonged, meanwhile, the loss of materials and spare parts is reduced, and the fault time is shortened.

Description

Technical Field

[0001] The invention relates to the field of locking cylinders, and in particular to a novel locking cylinder. Background Art

[0002] In the metallurgical machinery industry, locking hydraulic cylinders are often used to fix equipment. However, existing locking cylinders have design defects. During the production process, oil leakage from the rodless cavity often occurs, and the sealing ring is often damaged, resulting in internal oil leakage, causing excessive consumption of spare parts and increased costs.

[0003] Therefore, it is necessary to improve the existing locking cylinder to extend its service life, reduce oil leakage, and reduce the consumption of spare parts. Summary of the invention

[0004] Purpose of the invention: In view of the shortcomings and defects of the prior art, the present invention provides a new locking cylinder, which can extend the service life of the locking cylinder while reducing the loss of materials and spare parts and shortening the failure time.

[0005] Technical solution: A new type of locking cylinder of the present invention is characterized in that the rodless chamber seal is changed from a sealing ring to a set of seals, and the set of seals includes a shaft sealing ring and a step seal.

[0006] Wherein, the rodless cavity seal is used for the rodless cavity, and the rodless cavity seal is arranged on the side of the rodless cavity.

[0007] Wherein, the rodless cavity is located on the locking cylinder, and the rodless cavity is the rodless cavity of the locking cylinder.

[0008] When in use, on the basis of the existing locking cylinder, the length of the rodless cavity is lengthened, and the seal of the rodless cavity is changed from one sealing ring to a set of seals to perform double sealing.

[0009] When in use, an existing sealing ring is replaced with a shaft sealing ring and a step seal.

[0010] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages: the present invention reduces the leakage of hydraulic oil by improving the structure of the locking cylinder, increases the service life of the locking cylinder, and reduces the damage frequency of the locking cylinder and the cost of material spare parts consumption. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] In the figure, 1 is a rodless chamber seal. DETAILED DESCRIPTION

[0013] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0014] The novel locking cylinder of the present invention changes the rodless chamber seal 1 from a sealing ring to a set of seals, and the set of seals includes a shaft sealing ring and a step seal. Among them, the rodless chamber seal 1 is used for the rodless chamber, and the rodless chamber seal 1 is arranged on the side of the rodless chamber. The rodless chamber is located on the locking cylinder, and the rodless chamber is the rodless chamber of the locking cylinder.

[0015] When in use, on the basis of the existing locking cylinder, the length of the rodless chamber is lengthened, and the rodless chamber seal 1 is changed from a sealing ring to a set of seals for double sealing. When in use, the existing sealing ring is changed to a shaft sealing ring and a step seal. The step seal has excellent properties such as good dynamic and static sealing effect, high pressure resistance, low leakage, and simple structure.

[0016] The present invention reduces the leakage of hydraulic oil by improving the structure of the locking cylinder, increases the service life of the locking cylinder, and reduces the damage frequency of the locking cylinder and the cost of material spare parts consumption.
