Abstract
The utility model discloses a damping type door closer, which comprises a shell, a piston body and a closing shaft, wherein the closing shaft is positioned in a transverse perforation of the shell and is provided with a gear; the piston body is positioned in a closed cavity of the shell; the cavity is divided into two parts by a piston at one end part of the piston body; and the transverse perforation of the shell is arranged at the bottom of the closed cavity and is communicated with the cavity. The damping type door closer is characterized in that the outer surface of the piston body is provided with straight teeth, wherein the teeth are meshed with the gear arranged on the closing shaft in the transverse perforation; and a damping medium guide rod is arranged in the closed cavity of the shell and passes through the piston at the end part of the piston body to communicate the cavity on the right side and the left side of the piston body. By adopting the structure of the damping type door closer disclosed by the utility model, convenience is provided for repair or maintenance, and the maintenance time is shortened. The damping type door closer additionally has the characteristics of reasonable structure, low manufacturing cost, and the like.
Description
Technical field
The utility model relates to a kind of door closer, specifically is a kind of damp type door closer.
Background technology
Door closer is a hydraulic press of a last spring-like, can discharge by the compression back after door is opened, and door is shut automatically, and the effect of picture swinging door is arranged, and after can guaranteeing to be unlocked, is closed to initial position accurately, timely.When opening the door, the action of door body drivening rod, and travelling gear is rotated, drive the tooth bar plunger and move to right-hand.The process medi-spring that moves to right at plunger is compressed, and the hydraulic oil in the right chamber is pressurized also.The one way valve spheroid in plunger left side is opened under the effect of oil pressure, and the hydraulic oil in the right chamber flows in the left chamber through one way valve.After the process of opening the door was finished, because spring is compressed in opening process, the elastic potential energy of being put aside was released, and with the plunger thruster of turning left, drove travelling gear and door closer connecting rod and rotated, and door is closed.
The basic building block of traditional hydraulic pressure door closer that is used for closed door leaf has supporting guide, travelling gear, back-moving spring, one way valve, tooth bar plunger, throttling valve core and housing, end cap, sealing ring and connecting rod.Housing and connecting rod play a part fixedly door closer and are connected door leaf and doorframe, the enclosure interior space is full of resisting medium, and the enclosure interior space is divided at least two housing inner rooms hermetically by described piston fluid, the structure more complicated of this door closer, be not easy to maintenance, cost is higher.
Summary of the invention
The purpose of this utility model is above-mentioned door closer is improved, and a kind of low cost of manufacture, the rational in infrastructure and damp type door closer being convenient to keep in repair are provided.
To achieve these goals, the technical solution adopted in the utility model is: the damp type door closer, comprise housing, piston body and closed axle, in the horizontal perforation that closed is located on the housing, closed axle is provided with gear, described piston body is located in the enclosed cavity of housing, and the piston of piston body end is separated into two ones with cavity, it is characterized in that: described horizontal perforation communicates with this cavity; The external surface of described piston body is provided with straight-tooth, and the gear on the closed axle in this tooth and the horizontal perforation is meshed.
Be provided with the resisting medium guide rod in the enclosed cavity of described housing, the resisting medium guide rod passes the cavity connection of the piston of piston body end with the piston left and right sides.
The beneficial effects of the utility model: thus simplify the structure greatly, reduced cost, for the maintenance or the maintenance of door closer provides a great convenience, shortened maintenance time greatly.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a sectional side elevation shown in Figure 1.
Among the figure: 1, housing; 2, piston body; 3, closed axle; 4, horizontal perforation; 5, enclosed cavity; 6, straight-tooth; 7, gear; 8, resisting medium guide rod; 9, piston; 10, closing spring; 11, control valve; 12, guide hole.
The specific embodiment
As shown in Figure 1 and Figure 2, the damp type door closer includes housing 1, piston body 2, closed axle 3 and resisting medium guide rod 8, and resisting medium guide rod 8 passes the cavity connection of the piston 9 of piston body 2 ends with piston 9 left and right sides.Control valve 13 is equipped with in the end of resisting medium guide rod 8, and control valve 13 can block the guide hole 12 on resisting medium guide rod 8 sidewalls.Be provided with the enclosed cavity 5 of horizontal perforation 4 and level in the housing 1, horizontal perforation 4 is perpendicular with the enclosed cavity 5 of level, piston body 2 is positioned at sealed hollow 5, the piston 9 of piston body 2 ends is separated into two ones with cavity 5, closed axle 3 is positioned at horizontal perforation 4, the horizontal perforation 4 of described housing 1 be located at level enclosed cavity 5 the bottom and communicate with this cavity 5; The external surface of described piston body 2 is provided with straight-tooth 6, and set gear 7 is meshed on the closed axle 3 in this tooth and the horizontal perforation 4.
The course of work: when people open the door, door drive closer rotates, gear on the closed axle drive piston body that is meshed with the straight-tooth of piston body external surface moves along the enclosed cavity of level, piston body compression close spring 10, staff is after opening door body, door can be closed door under the elastic force of closing spring automatically, because of the excessive velocities of closing the door might opposite house causes damage and also can produce certain noise, for addressing the above problem, the inner space of housing has been full of resisting medium, when closing spring promotion piston is mobile in housing, resisting medium just by the resisting medium guide rod from the cavity flow of piston one side cavity to the piston opposite side, resisting medium is slower by the speed in hole 12, under the resistance of resisting medium, the closure of closing spring is played the effect of buffering, thereby can slow down its speed of closing the door.Since the horizontal perforation of housing be located at level enclosed cavity the bottom and communicate with this cavity, make closed axle, be positioned at the below of piston body and the set straight-tooth of gear and the external surface of piston body on the closer axle is meshed, pass in piston body thereby changed traditional closed axle, and the structure that is meshed with needle roller in the piston body.
In a word; though the utility model has been enumerated above-mentioned preferred implementation; but should illustrate; though those skilled in the art can carry out various variations and remodeling; unless such variation and remodeling have departed from scope of the present utility model, otherwise all should be included in the protection domain of the present utility model.
