Abstract
The utility model discloses an oil cylinder rust preventing device for a flange type cylinder cover. The oil cylinder rust preventing device for the flange type cylinder cover comprises a cylinder barrel flange and a cylinder cover. A chamfer is arranged at a position where the end face of the cylinder barrel flange is matched with the cylinder cover. A seal ring is arranged in the chamfer in a sealing mode. According to the oil cylinder rust preventing device for the flange type cylinder cover, different sizes of the chamfer are adopted according to different specifications of an adopted O-shaped ring, the inside of the cylinder barrel flange is chamfered, the waterproof O-shaped ring is additionally arranged, and therefore the effect that external liquid is prevented from seeping into an oil cylinder to exert adverse effects on the oil cylinder is achieved; on the principles that the cylinder cover is not changed and the interchangeability of the cylinder cover is not affected, only the chamfer position of a cylinder barrel is changed, therefore, processing cost is not increased, the repair rate of the oil cylinder is greatly lowered, cost for three guarantees (for repair, replacement and compensation of faulty products) is reduced, operation is easy, feasibility is high, and the purposes of water resistance and rust prevention are effectively achieved.
Description
Technical field
The utility model relates to technical field of hydraulic oil cylinder, relates to the device of the hydraulic loader oil cylinder antirust processing in cylinder cap place of flange-type cylinder cap.
Background technique
At present, in construction machinery product, because the continuous upgrading of product, the quality of oil cylinder promotes, the improvement of the product development trend that is inevitable.We adopted the cylinder barrel flange directly to cooperate with the cylinder cap end face in the past for the flange-type cylinder cap, as shown in Figure 1, comprise: comprise cylinder barrel flange A and cylinder cap B, its structure that adopts is that the cylinder barrel flange directly cooperates with the cylinder cap end face, the said structure existing problems are: use under abominable physical environment oil cylinder installation back, liquid such as rainwater infiltrate in the oil cylinder by the counterface slit, cause oil cylinder inside to get rusty, and have a strong impact on working life.
The model utility content
For solving the technical problem that exists in the prior art, the utility model provides a kind of oil cylinder of flange-type cylinder cap the anti-device that gets rusty, and the waterproof antirust function that it can effectively improve oil cylinder increases the service life.
The utility model solves the problems of the technologies described above, and the technological scheme that adopts is:
The anti-device that gets rusty of the oil cylinder of flange-type cylinder cap comprises cylinder barrel flange and cylinder cap, and described cylinder barrel end face of flange and cylinder cap cooperation position are provided with chamfering, and seal ring is arranged in the chamfering and seals.
Concrete, described seal ring is O shape circle.
Adopt technique scheme, the utility model is because according to selecting for use different O shape circle specifications to select different chamfer dimesions for use, with the inner chamfering of cylinder barrel flange and increase waterproof O shape circle, stop outside liquid seepage flow to go into oil cylinder inside to reach, the harmful effect that oil cylinder is produced.Do not change cylinder cap, do not influence cylinder cap interchangeability in principle, only cylinder barrel chamfering place is changed, do not increase processing cost, and reduced the repair rate of oil cylinder greatly, save three guarantees and reprocess cost, easy to operate, the feasibility height effectively reaches the antirust purpose of waterproof.
Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present utility model, constitutes a part of the present utility model, and illustrative examples of the present utility model and explanation thereof are used for explaining the utility model, do not constitute improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the utility model prior art structural representation;
Fig. 2 is the utility model structural representation.
Embodiment
In order to make technical problem to be solved in the utility model, technological scheme and beneficial effect clearer, clear, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
As shown in Figure 2, the anti-device that gets rusty of the oil cylinder of flange-type cylinder cap comprises cylinder barrel flange 1 and cylinder cap 2, and described cylinder barrel flange 1 end face and cylinder cap cooperation position are provided with chamfering 11, and sealing O shape circle 3 is arranged in the chamfering and seals.
The utility model is according to selecting for use different O shape circle specification to select different chamfer dimesions for use, with the inner chamfering of cylinder barrel flange and increase waterproof O shape circle, stops outside liquid seepage flow to go into oil cylinder inside to reach, the harmful effect that oil cylinder is produced.Do not change cylinder cap, do not influence cylinder cap interchangeability in principle, only cylinder barrel chamfering place is changed, do not increase processing cost, and reduced the repair rate of oil cylinder greatly, save three guarantees and reprocess cost, easy to operate, the feasibility height effectively reaches the antirust purpose of waterproof.
Above-mentioned explanation illustrates and has described preferred embodiment of the present utility model, as previously mentioned, be to be understood that the utility model is not limited to the disclosed form of this paper, should not regard the eliminating to other embodiments as, and can be used for various other combinations, modification and environment, and can in model utility contemplated scope described herein, change by technology or the knowledge of above-mentioned instruction or association area.And the change that those skilled in the art carry out and variation do not break away from spirit and scope of the present utility model, then all should be in the protection domain of the utility model claims.
Claims (2)
