Abstract
The utility model relates to a hydraulic oil cylinder with a location lock, which comprises a cylinder body, a front cylinder cover, a rear cylinder cover, a piston and a piston rod. The front cylinder cover and the rear cylinder cover are respectively fixed at two ends of the cylinder body in sealing mode, the piston capable of reciprocating in the cylinder body is arranged in the cylinder body, the piston rod is fixed on the piston and provided with a location hole, and the cylinder body is provided with a location lock matched with the location hole. The hydraulic oil cylinder is provided with the location lock, thereby being capable of locating the piston rod and avoiding displacement of the piston rod, improving stability of the hydraulic oil cylinder and being safe to use.
Description
[technical field]
The utility model relates to a kind of hydraulic jack with the location lock, belongs to the hydraulic equipment technical field.
[background technique]
Hydraulic jack is a constituent elements commonly used in the machinery, and it is made up of cylinder body, piston rod and piston etc. usually forms, and in use, piston rod drives piston reciprocates.
Yet the hydraulic jack of existing technology can not self-locking, and when it receives under deadweight or the external load long lasting effect, piston rod can be subjected to displacement, thereby influences the working stability of this hydraulic jack, even causes security incident.
Therefore, for solving the problems of the technologies described above, the necessary hydraulic jack that provides a kind of with the location lock is to overcome said defective of the prior art.
[model utility content]
For addressing the above problem, the purpose of the utility model is to provide the hydraulic jack of high, the safe in utilization band location lock of a kind of stability.
For realizing above-mentioned purpose, the technological scheme that the utility model is taked is: a kind of hydraulic jack with the location lock, and it comprises cylinder body, front end housing, back cylinder cover, piston and piston rod; Wherein, said front end housing and back cylinder cover difference sealing and fixing is at the two ends of cylinder body; Said piston is contained in the cylinder body and can to-and-fro motion in cylinder body; Said piston rod is fixed on the piston, is provided with a positioning hole on it; Said cylinder body is provided with the location lock of an ability and positioning hole cooperation.
The hydraulic jack of the band location lock of the utility model further is set to: on said piston rod, further be arranged with a guide sleeve; This guide sleeve is fixed on the back cylinder cover.
Compared with prior art, the utlity model has following beneficial effect: the hydraulic jack of the utility model is locked through a location is set, thereby can and not be subjected to displacement this piston rod location, has improved the stability of this hydraulic jack, and safe in utilization.
[description of drawings]
Fig. 1 be the utility model band location lock hydraulic jack partly cut open figure.
[embodiment]
See also shown in the Figure of description 1, the utility model is a kind of hydraulic jack with the location lock, and it is made up of members such as cylinder body 1, front end housing 2, back cylinder cover 3, piston 4 and piston rods 5.
Wherein, said cylinder body 1 adopts stainless steel material to process.Said front end housing 2 and the two ends of back cylinder cover 3 difference sealing and fixing at cylinder body 1.Said piston 4 is contained in also can be reciprocating in cylinder body 1 in the cylinder body 1.Said piston rod 5 is fixed on the piston 4, and promotes piston 4 motions.On said piston rod 5, further be arranged with a guide sleeve 6; This guide sleeve 6 is fixed on the back cylinder cover 3 through screw 7, and this guide sleeve 6 is used to guide piston rod 5 motions, prevents its deflection.
The hydraulic jack greatest improvement part of the utility model is: be provided with a positioning hole 51 in said piston rod 5.Said cylinder body 1 is provided with the location lock 11 of an ability and positioning hole 51 cooperations, and when an end of location lock 11 was housed in the positioning hole 51, piston rod 5 was difficult for being subjected to displacement, and has improved the stability of this hydraulic jack, and safe in utilization; And need not lock the time, only need extract location lock 11 and get final product.
Above embodiment is merely the preferred embodiment of this creation, not in order to limiting this creation, any modification of being made within all spirit and principles in this creation, is equal to replacement, improvement etc., all should be included within the protection domain of this creation.
Claims (2)
