Abstract
The invention provides a buffer hydraulic cylinder for a forklift. The buffer hydraulic cylinder comprises an oil guide port (4), an oil outlet (4a), a plug (6), a guide sleeve (7), a connecting rod (2) and a piston (3), wherein the oil guide port (4) and the oil outlet (4a) are arranged on a cylinder body (1), the plug (6) and the guide sleeve (7) are arranged at two ends of the cylinder body (1) respectively, the connecting rod (2) matched with the guide sleeve is arranged in the guide sleeve (7), and the piston (3) matched with the cylinder body (1) is disposed at one end of the connecting rod (2). The buffer hydraulic cylinder is characterized in that a circle of chamfers (5) is arranged on the thrust end face of the piston (3). The buffer hydraulic cylinder for the forklift has the advantages that the structure is simple, the manufacture is convenient, vibration due to direct impact of hydraulic oil to the piston is reduced, and the stability and the safety of the forklift during operation are improved.
Description
Technical field:
The present invention relates to a kind of oil hydraulic cylinder, particularly be the fork truck buffering hydraulic cylinder.
Background technique:
At present, the employed oil hydraulic cylinder of fork truck, the hydraulic oil in the cylinder all are the utilizations that directly promotes piston.But hydraulic oil can produce certain impact force when contacting with the piston stress surface, vibrates thereby drive oil hydraulic cylinder, and when particularly fork truck was lifted higher position with article, this vibration was particularly evident, stability and Security in the time of can having influence on forklift operator.
Purpose of the present invention:
The present invention just is based on solution, and present employed oil hydraulic cylinder is on-stream can to produce certain vibration, thereby the stability when influencing forklift operator and the problem of Security provide a kind of fork truck buffering hydraulic cylinder.
To achieve these goals, the invention provides following technological scheme:
The fork truck buffering hydraulic cylinder, it comprises: be provided with oil diverting port, oil outlet at cylinder body, be respectively equipped with plug, guide sleeve at the cylinder body two ends, in guide sleeve, be provided with the connecting rod that cooperates with its formation, end at connecting rod is provided with the piston that cooperates with cylinder body formation, it is characterized in that: a stressed end face at described piston is provided with a circle chamfering.
On the basis of technique scheme, following further technological scheme can also be arranged:
On another stressed end face of described piston, also be provided with a circle chamfering.
The invention has the advantages that:
Advantage of the present invention is simple in structure, easily manufactured, reduces hydraulic oil to the direct bump of piston, the vibration that produces, thus improve stability and the Security of fork truck when work.
Description of drawings:
Fig. 1 is plan view of the present invention;
Fig. 2 is A portion enlarged view among Fig. 1.
Embodiment:
As Fig. 1, shown in, the fork truck buffering hydraulic cylinder, it comprises: be provided with oil diverting port (4) and oil outlet (4a) at cylinder body (1), be respectively equipped with plug (6), guide sleeve (7) at cylinder body (1) two ends, in guide sleeve (7), be provided with the connecting rod (2) that cooperates with its formation, end at connecting rod (2) is provided with the piston (3) that cooperates with cylinder body (1) formation, it is characterized in that: the stressed end face at described piston (3) is provided with a circle chamfering (5).
As shown in Figure 2, on the end face at the two ends of the stressed end face of described piston (3), all be provided with a circle chamfering (5).
By the mode of a circle chamfering (5) is set at piston (3), make piston (3) and the area of hydraulic oil connecting part increase, reduce hydraulic oil to the moment impact force of piston (3) stress surface thereby play, reduced the purpose of the vibration of oil hydraulic cylinder, stability and Security when therefore also just having improved the fork truck running.
Claims (2)
1. fork truck buffering hydraulic cylinder, it comprises: be provided with oil diverting port (4) and oil outlet (4a) at cylinder body (1), be respectively equipped with plug (6), guide sleeve (7) at cylinder body (1) two ends, in guide sleeve (7), be provided with the connecting rod (2) that cooperates with its formation, end at connecting rod (2) is provided with the piston (3) that cooperates with cylinder body (1) formation, it is characterized in that: a stressed end face at described piston (3) is provided with a circle chamfering (5).
2. according to the buffering hydraulic cylinder described in the claim 1, it is characterized in that: on another stressed end face of described piston (3), also be provided with a circle chamfering (5).
