Abstract
The utility model discloses a door closer for horizontal sliding door, comprising an air cylinder cover (5), an air cylinder body (7), an air cylinder head (14), a fixing frame (6) and a fixed seat (1), wherein the air cylinder head (14) is provided with an air inlet (17) and an air outlet (16); the air cylinder body (7) is provided inside with a hollow piston rod (4) and a second piston (12) fixed on the hollow piston rod (4), wherein the head of the hollow piston rod (4) is provided with an end cap (3) and extends out of the air cylinder cover (5), the inside of the hollow piston rod (4) is provided a fixed piston rod (2) and a first piston (10) fixed on the fixed piston rod (2); the fixed piston rod (2) is provided with a restoring spring (8), the first piston (10) is provided with a gas vent (19), the head of the fixed piston rod (2) extends out of an end cap (3); with the above structure, the utility model has the advantages of simple and reasonable structure, easy manufacture, convenient assembly and maintenance, low cost and stability and reliability of work.
Description
One, technical field
The utility model relates to a kind of door closer, particularly a kind of door closer that is used for horizontal sliding door.
Two, background technology
Existing horizontal sliding door door closer generally adopts hydraulic structure, realizes that by hydraulic drive manual push-and-pull opens the door, automatically resets; But the horizontal push-and-pull door closer of fluid pressure type exists following weak point: the one, and the requirement on machining accuracy height, difficulty of processing is big, cost is high, popularizes in an all-round way and uses comparatively difficulty; The 2nd, install inconvenient; The 3rd, after damaging, the maintenance cost height is repaired difficulty.
Three, summary of the invention
For overcoming the above-mentioned disadvantage that existing level sliding door door closer exists, the utility model provides a kind of simple and reasonable, handling ease, installation to repair horizontal easily sliding door door closer.The technical scheme that its technical problem that solves the utility model adopts comprises cylinder head, cylinder block, cylinder head, the fixed mount of fixed air cylinder body and be fixed in holder on the sliding door, cylinder head is provided with air inlet and the venthole that communicates with cylinder block, described cylinder block inside is provided with hollow piston bar and second piston that is fixed on the hollow piston bar, on the hollow piston bar in cylinder block back-moving spring is set, the head of hollow piston bar is provided with end cap and stretches out cylinder head, hollow piston bar inside is provided with piston rod and the first piston that is fixed on the piston rod, be provided with back-moving spring on the piston rod in the hollow piston bar, first piston is provided with gas port, and the head of piston rod stretches out end cap and is connected with holder.
Be provided with first joint ring and second joint ring on the described first piston and second piston successively.
Described air inlet is provided with one way valve, is provided with control valve in the described venthole.
After adopting said structure, owing to adopted two groups of piston apparatus that are linked in together, elastic force by back-moving spring automatically resets, can satisfy enough push-and-pull distances, can shorten the length of piston rod again, make the door closer structure compact more, simultaneously, setting by one way valve and control valve, can make door closer when opening the door, not have the air pressure resistance, the elastic force that only need overcome back-moving spring can spur, and door closer need overcome the air pressure resistance when automatically reseting under the elastic force effect of back-moving spring, can make sliding door steadily closed like this; Have simple and reasonable, handling ease, advantages such as convenient, that cost is low, working stability is reliable are repaired in installation.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model.
Five, the specific embodiment
Shown in Figure 1, embodiment for horizontal sliding door door closer of the present utility model, it comprises cylinder head 5, cylinder block 7, cylinder head 14, the fixed mount 6 of fixed air cylinder body 7 and be fixed in holder 1 on the sliding door, cylinder head 14 is provided with air inlet 17 and the venthole 16 that communicates with cylinder block 7, described cylinder block 7 inside are provided with hollow piston bar 4 and second piston 12 that is fixed on the hollow piston bar 4, second piston 12 is provided with second joint ring 13, on the hollow piston bar 4 in cylinder block 7 back-moving spring 9 is set, the head of hollow piston bar 4 is provided with end cap 3 and stretches out cylinder head 5, hollow piston bar 4 inside are provided with piston rod 2 and the first piston 10 that is fixed on the piston rod 2, first piston 10 is provided with first joint ring 11, be provided with back-moving spring 8 on the piston rod 1 in hollow piston bar 4, first piston 10 is provided with gas port 19, first piston 10 inner and outer air pressures are kept substantially with pressing, reduce the air pressure resistance, the head of piston rod 1 stretches out end cap 3 and is connected with holder 1.Described air inlet 17 is provided with one way valve 18, be provided with control valve 15 in the described venthole 16, make sliding door when opening, not have the air pressure resistance, keep certain pressure during auto-closing in the cylinder block 7, the assurance sliding door is steadily closed, and the speed of sliding door closing velocity can be by control valve 15 controls.
