Abstract
The utility model discloses a door closer, comprising a body and a connecting rod. The connecting rod is in the body and is sheathed with a spring; one end of the connecting rod is connected with a pressure plate that a driving shaft can drive and the other end is connected with a piston; the body is located at one end of the piston and is covered with a cover; and a magnet is inserted in the inner wall of the cover. The magnet of the door closer can adsorb scrap iron derived from attrition, therefore, the performance of the door closer is good, and service life becomes long greatly.
Description
Technical field
The utility model relates to a kind of door closer, specifically, relates to a kind of improvement of door closer.
Background technology
At present, on a lot of doors, door closer usually is installed, and the kind of door closer is more, wherein, a kind of door closer comprises body, connecting rod and power transmission shaft, and connecting rod and is with spring in body, one end of connecting rod is connected with piston, the other end is connected with pressing plate, and three runners and the rectangular groove that two ends are semi arch are arranged on the pressing plate, and pressing plate is enclosed within on the power transmission shaft by this groove, can be and also be equipped with on the power transmission shaft with the cam of power transmission shaft rotation, the end cap that body is positioned at piston has capping.
When opening Door by Hand, because door is installed in (i.e. the axle center of door rotation) on the power transmission shaft, power transmission shaft rotating band moving cam rotates, and cam makes pressing plate pass through the rectangular groove of semi arch by the runner on the promotion pressing plate and moves when rotating, thus, the pressing plate drivening rod moves to axis direction, thereby makes piston also move to axis direction, in the piston moving process, can compress spring, also can allow internal hydraulic pressure oil flow to capping place; When decontroling hand, reply because of spring force, make piston, connecting rod etc. return and reset that internal hydraulic pressure oil flows back to the capping direction.
In actual applications, door closer is according to above-mentioned operating principle work; Under functional operation, the friction mutually of each position part such as body and piston, spring and connecting rod can derive iron filings relatively in the friction process.Iron filings are in service at internal oil passages, and the through hole to oil circuit causes obstruction easily, cause having adjustment door switch speed instability, door can't stop (excessive velocities of closing the door) or the element of dust friction oil sealing and cause leakage of oil, therefore, the poor-performing of this door closer, application life is shorter.
The utility model content
At the problems referred to above, the purpose of this utility model is to provide the door closer that a kind of performance is good, application life is long.
For realizing described purpose, the technical scheme that the utility model adopted is: a kind of door closer, comprise body, connecting rod and power transmission shaft, described connecting rod is in body, and be with spring, one end of connecting rod is connected with piston, the other end is connected with pressing plate, described pressing plate has three runners and the rectangular groove that two ends are semi arch, pressing plate is enclosed within on the power transmission shaft by this groove, having on the described power transmission shaft can be with the cam of power transmission shaft rotation, and the end cap that described body is positioned at piston has capping, is embedded with magnet on the inwall of described capping.
Described magnet can replace with magnetisable material.
Described connecting rod can have several.
Although door closer of the present utility model is identical with described existing door closer operating principle, in the reciprocating motion process of opening the door and closing the door, because of inner body rubs frequent, just be easy to generate iron filings, iron filings flow in oil circuit through hole are had manifesting of accumulation, make a disabler, but owing to be embedded with magnet on the inwall of capping, utilize the attraction of magnet, be adsorbed on the iron filings that friction is derived in the oil circuit, reduce the contingent failure state of iron filings, promoted properties of product, thereby the performance of door closer of the present utility model is good, and application life is elongated greatly.
In addition, magnet can replace with magnetisable material as required, and connecting rod can be designed to several.
Description of drawings
Fig. 1 is the door closer structural representation of utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Show as Fig. 1, a kind of door closer, comprise body 4, connecting rod 5 and power transmission shaft 8, described connecting rod 5 is in body 4, and be with spring 6, one end of connecting rod 5 is connected with piston 3, the other end is connected with pressing plate 7, described pressing plate 7 has three runners 9 and the rectangular groove 10 that two ends are semi arch, pressing plate 7 is enclosed within on the power transmission shaft 8 by this groove, having on the described power transmission shaft 8 can be with the cam 11 of power transmission shaft rotation, and the end cap that described body 4 is positioned at piston 3 has capping 1, is embedded with magnet 2 on the inwall of described capping 1.
When opening Door by Hand, because door is installed in (i.e. the axle center of door rotation) on the power transmission shaft 8, power transmission shaft 8 rotating band moving cams 11 rotate, and cam 11 makes pressing plate 7 move by the rectangular groove 10 of semi arch by the runner 9 that promotes on the pressing plate 7 when rotating, thus, pressing plate 7 drivening rods 5 move to axis direction, thereby make piston 3 also move to axis direction, in piston 3 moving process, can compress spring 6, also can allow internal hydraulic pressure oil flow to capping 1 place; When decontroling hand,, make piston 3, connecting rod 5 etc. return and reset that internal hydraulic pressure oil flows back to capping 1 direction because of spring 6 elastic returnings.
In the reciprocating motion process of opening the door and closing the door, frequent because of the inner body wearing and tearing, just be easy to generate iron filings, iron filings flow in oil circuit through hole are had manifesting of accumulation, make a disabler, but owing to be embedded with magnet 2 on the inwall of capping 1, utilize the attraction of magnet 2, be adsorbed on the iron filings that friction is derived in the oil circuit, reduce the contingent failure state of iron filings, promoted properties of product, thereby the performance of door closer of the present utility model is good, application life is elongated greatly.
In addition, magnet 1 can replace with magnetic nickel as required, and connecting rod 5 can be two.
The above is a preferred implementation of the present utility model.The utility model can also be made various flexible frame mode in same area or association area, more than by the specific embodiment by the accompanying drawing illustrated embodiment, be to further describing that foregoing of the present utility model is made, but this should be interpreted as that the scope of the theme that the utility model is above-mentioned only limits to described example.Under the situation that does not break away from the above-mentioned technological thought of the utility model, various replacements and change according to ordinary skill knowledge and customary means are made all should be included in the protection domain of the present utility model.
