Description
Technical field
The utility model relates to a kind of door limiting device, and more particularly, the utility model relates to a kind ofly realizes the air exercise spacing device of practicing backdoorism by the pull sleeve part, belongs to the Hardware fitting technical field.
Background technology
At present, door limiting device has varied, and common have pneumatic strut, a curved bar etc.When using pneumatic strut, after door was opened, the elastic force that compressed gases at high pressure produce in the pneumatic strut played portal bracing spacing.Because after pneumatic strut used for a long time, the phenomenon that can leak gas caused pneumatic strut air pressure deficiency, can not spacingly fix after door is opened, even cause door to be closed again, exist unsafe factor.Existing curved bar structures door limiting device adopts steel plate to be bent into the form of curved bar, utilize several places pin-and-hole that is provided with on the curved bar and pin to flexibly connect opposite house and carry out spacingly, this door stop exists the processing request height, and structure is insecure, defectives such as easy becoming flexible damaged, and profile is coarse.
The utility model content
The purpose of this utility model is in order to overcome the inconvenient operation that existing door limiting device exists, loaded down with trivial details effort, poor reliability, shortcomings such as profile is not attractive in appearance provide a kind of drawing and pulling type door limiting device, this apparatus structure compactness, the reliability height, rapid operation, convenience, good looking appearance.
The utility model is achieved by the following technical programs:
A kind of drawing and pulling type door limiting device, comprise mobile jib, secondary bar, claw, bearing pin, block, the shape of cross section of described mobile jib, secondary bar is identical, and an end of secondary bar is sleeved in the mobile jib, both matched in clearance, the termination that mobile jib, secondary bar deviate from the suit place is respectively equipped with pin-and-hole; The top side of described mobile jib and secondary bar has mobile jib groove, secondary bar groove, and a side of described secondary bar has straight-through elongated slot; Described claw is arranged in the end of secondary bar, and is hinged by bearing pin and secondary bar both sides; Described block is fixedly installed on the inboard of mobile jib suit end port, and an end of claw was stuck on the notch of mobile jib groove when the door unlatching was spacing.
The purpose of this utility model can also further realize by following technical measures.
Aforesaid a kind of drawing and pulling type door limiting device, vertical two ends of wherein said claw are provided with indent V-arrangement pawl mouth, and when the door unlatching was spacing, claw rotated around bearing pin, and one end V-arrangement pawl mouth is stuck on the notch of mobile jib groove.
Aforesaid a kind of drawing and pulling type door limiting device, wherein said block is L shaped, and described L shaped vertical edges is fixedlyed connected with mobile jib suit end port inboard, and when door was closed, described L shaped horizontal sides downside was higher than on the lower claw point that is in the level claw.
Advantage of the present utility model is, simple and compact for structure, easy to assembly, good looking appearance, low cost of manufacture, rapid operation is convenient, reliability is high.
Advantage of the present utility model and characteristics will illustrate by the non-limitative illustration of following preferred embodiment and explain that these embodiment only provide as an example with reference to accompanying drawing.

Fig. 1 is the schematic diagram that the utility model is in collecting state;
Fig. 2 is that the utility model is in the schematic diagram that will draw back;
Fig. 3 is that the utility model is in the schematic diagram that draws back spacing state,
Fig. 4 is the A-A cutaway view Amplified image of Fig. 3.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As Fig. 1～shown in Figure 4, the utility model comprises mobile jib 1, secondary bar 2, claw 3, bearing pin 4, block 5, the mobile jib 1 of present embodiment and secondary bar 2 are the stainless steel tube of square-section, and good looking appearance and antirust, mobile jib 1 and secondary bar 2 also can adopt the steel pipe of parallel other cross sectional shapes of both sides tube wall.One end of secondary bar 2 is sleeved in the mobile jib 1, and both matched in clearance are convenient to secondary bar 2 and are slided in mobile jib 1.The termination that mobile jib 1, secondary bar 2 deviate from the suit place is respectively equipped with mobile jib pin-and-hole 12, secondary lever pin hole 22, is respectively applied for and door and being connected of doorframe pivoting support.The top side of mobile jib 1 and secondary bar 2 has mobile jib groove 11, secondary bar groove 21, is used for the utility model and draws back when spacing, and claw 3 lifts spacing.Block 5 is fixedly installed on the inboard of mobile jib 1 suit end port, and block 5 is L shaped, and described L shaped vertical edges is connected with mobile jib 1 suit end port is inboard, and a side of secondary bar 2 has straight-through elongated slot 23, is convenient to block 5 and slides in the straight-through elongated slot 23 of secondary bar 2.Claw 3 is arranged in the end of secondary bar 2, and bearing pin 4 successively passes secondary bar 2 and claw 3, fixedlys connected with the riveted joint of secondary bar 2 both sides or other modes in its two ends.Be provided with packing ring 6 respectively between the both sides of claw 3 and mobile jib 1 inwall, prevent that claw 3 is stuck, the middle part of bearing pin 4 and claw 3 are hinged, and claw 3 two ends are provided with the V-arrangement pawl mouth 31 of indent.
For the ease of assembling, the utility model mobile jib 1 one sides have the mobile jib elongated slot, and secondary bar 2 one sides have secondary bar elongated slot, after assembling finishes, respectively mobile jib elongated slot shrouding 13, secondary bar elongated slot shrouding 24 are inlaid on the elongated slot, adopt spot welding or bonding method that each shrouding is fixedlyed connected with elongated slot separately.
As Fig. 2, shown in Figure 3, when door is opened when spacing, because block 5 horizontal sides 51 downsides are higher than the lower claw point 32 that is in level claw 3, outwards spur secondary bar 2, L shaped block 5 horizontal sides 51 of mobile jib 1 are withstood on the lower claw point 32 that is in level, when door is opened to certain angle, promote secondary bar 2 then inwards, the lower claw point 32 that block 5 horizontal sides 51 promote, claw 3 is rotated counterclockwise around bearing pin 4, promote secondary bar 2 more inwards, the V-arrangement pawl mouth 31 of claw 3 front ends is stuck on the notch of mobile jib groove 11 makes the thresholding position.
As shown in Figure 1, when door is closed, earlier outwards spur secondary bar 2 slightly, make mobile jib groove 11 notch positions shift out the V-arrangement pawl mouth 31 of claw 3, claw 3 constraint reliefs, claw 3 clockwise rotates until being in the horizontal equilibrium state around bearing pin 4 under the effect of dead-load moment, at this moment, the outer side edges 33 of claw 3 is equal with the lateral surface of secondary bar 2, promotes secondary bar 2 then inwards, the inwall that claw 3 is pasting mobile jib 1 slides inwards, closes until door.
In addition to the implementation, the utility model can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
