Abstract
The utility model discloses a high precision excellent abrasion-resistant steel cylinder body door closer, which comprises a hydraulic cylinder body, wherein the hydraulic cylinder body is formed as follows: excellent abrasion-resistant steel material is adopted to be undertaken the high precision and accurate processing to form a cylinder body, and aluminum alloy is molded through the positioning of the mould to form a housing. Since the hydraulic cylinder body of the door closer adopts the excellent abrasion-resistant steel material, the abrasion resistance is greatly improved, and the service life of the door closer is prolonged.
Description
Technical field
The utility model relates to a kind of automatic door closer, thereby the improvement that specifically is meant a kind of hydraulic cylinder to automatic door closer improves its abrasion resistance so that improve the wear-resisting steel cylinder body of the high accuracy high-quality door closer in application life.
Background technology
At present, the hydraulic cylinder of the door closer of selling, using on the market all is the housing structure that adopts aluminium to make, the anti-wear performance of hydraulic cylinder is poor, so in long-term use, easily wearing and tearing, thus application life of door closer shortened greatly, to door closer frequent maintenance and replacing, bring great inconvenience not only for normal the use, but also can influence normal life.
The utility model content
In order to overcome above-mentioned deficiency, the purpose of this utility model is to provide that a kind of anti-wear performance is good, the wear-resisting steel cylinder body of the high accuracy high-quality door closer of long service life.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: the wear-resisting steel cylinder body of a kind of high accuracy high-quality door closer, include hydraulic cylinder, described hydraulic cylinder is to adopt the wear-resisting steel of high-quality, after process high accuracy, Precision Machining become cylinder body, form with the aluminium alloys cast envelope by the mould location.
The beneficial effects of the utility model are: because the hydraulic cylinder of door closer has adopted the wear-resisting steel of high-quality, improved its abrasion resistance greatly, prolonged the application life of door closer.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a vertical view shown in Figure 1;
Fig. 3 is the structural representation of hydraulic cylinder shown in Figure 1.
The specific embodiment
As Fig. 1, Fig. 2, shown in Figure 3, the wear-resisting steel cylinder body of high accuracy high-quality door closer comprises hydraulic cylinder 1, piston 2, closes a speed-regulating valve 3, shell 4, spring 5, gear 6, described hydraulic cylinder 1 is to adopt the wear-resisting steel of high-quality, after process high accuracy, Precision Machining become cylinder body, form with the aluminium alloys cast envelope by the mould location.
