Description
Technical field
The utility model relates to the technical field of door and window hardware, particularly relates to a kind of along door device.
Background technology
Being used for two fan labeled doors along door device, is to ensure that when fire alarm two fan door and close in order, avoids two fan doors to close and the situation generation blocked simultaneously.Install along after door device, can ensure that Yishanmen is closed rear another Yishanmen completely and could be closed, ensure that two fan doors can not block, usually coordinate door closer to use together along door device.In the prior art, relatively seriously, described slide bar is all commercially adopt rectangular configuration, is that face contacts with first closing the door, and after using a period of time, labeled door has obvious cut for the slide bar of suitable door device and the wearing and tearing of pair of rollers labeled door.
In view of this, the present inventor studies and devises a kind of along door device, and this case produces thus.
Utility model content
The purpose of this utility model is to provide a kind of along door device, to solve the having a double meaning labeled door of prior art easily by the wear problem along door device.
To achieve these goals, the technical scheme in the invention for solving the technical problem is:
A kind of along door device, comprise pedestal, slide bar and roller, described pedestal is provided with U-shaped cavity and screw rod, described pedestal is located on the doorframe of having a double meaning labeled door, described slide bar comprises fixed end, connecting portion and free end, and described fixed end is located on described U-shaped cavity by torsion spring in mobilizable mode, and described screw rod props up on the sidewall of described fixed end in the mode that screw thread is adjustable, described roller is located on described free end, described roller slidably with after close the door and contact; Described connecting portion adopts cylindrical structural, and described connecting portion is contacted with first closing the door by the mode of linear contact lay.
As the preferred embodiment of embodiment, also comprise abrasionproof part, described abrasionproof part is inverted L shape, and on described abrasionproof part is located at and first closes the door, described connecting portion contacts with described abrasionproof part.
As the preferred embodiment of embodiment, also comprise chafing strip, on closing the door after described chafing strip is located at, described roller slidably contacts with described chafing strip.
Above-mentioned technical scheme is have employed along door device because the utility model is a kind of, namely pedestal, slide bar and roller is comprised, described pedestal is provided with U-shaped cavity and screw rod, described pedestal is located on the doorframe of having a double meaning labeled door, described slide bar comprises fixed end, connecting portion and free end, described fixed end is located on described U-shaped cavity by torsion spring in mobilizable mode, described screw rod props up on the sidewall of described fixed end in the mode that screw thread is adjustable, described roller is located on described free end, described roller slidably with after close the door and contact; Described connecting portion adopts cylindrical structural, and described connecting portion is contacted with first closing the door by the mode of linear contact lay; Make described slide bar less with the friction of first closing the door, effectively prevent along door device the wearing and tearing of having a double meaning labeled door.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model abrasionproof part.
Fig. 3 is the structural representation of the utility model chafing strip.
Detailed description of the invention
As shown in Figure 1, the utility model discloses a kind of along door device, comprise pedestal 1, slide bar 2 and roller 3, described pedestal 1 is provided with U-shaped cavity 11 and screw rod 12, described pedestal 1 is located on the doorframe of having a double meaning labeled door, described slide bar 2 comprises fixed end 21, connecting portion 22 and free end 23, described fixed end 21 is located on described U-shaped cavity 11 by torsion spring in mobilizable mode, described screw rod 12 props up on the sidewall of described fixed end 21 in the mode that screw thread is adjustable, described roller 3 is located on described free end 23, described roller 3 slidably with after close the door and contact; Described connecting portion 22 adopts cylindrical structural, and described connecting portion 22 is contacted with first closing the door by the mode of linear contact lay.
As the preferred embodiment of embodiment, as shown in Figure 2, also comprise abrasionproof part 4, described abrasionproof part 4 is inverted L shape, and on described abrasionproof part is located at and first closes the door, described connecting portion 22 contacts with described abrasionproof part 4.
As the preferred embodiment of embodiment, as shown in Figure 3, also comprise chafing strip 5, on closing the door after described chafing strip 5 is located at, described roller 3 slidably contacts with described chafing strip 5.
When using the utility model structure, when after close the door first close time, on the chafing strip of closing the door after being against along the roller of door device, after close the door and temporarily can not close, now, waiting for first closes the door first shuts, abrasionproof part contacts with described connecting portion, and then promotes slide bar, by after close the door and shut.The utility model slide bar adopts cylindrical structural, takes abrasionproof part at slide bar and the contact position of first to close the door, roller with after the contact position of closing the door take chafing strip, can the having a double meaning labeled door of available protecting by the wearing and tearing along door device.
The above, be only the utility model preferred embodiment, therefore the scope that the utility model implements can not be limited according to this, the equivalence namely done according to the utility model the scope of the claims and description change with modify, all should still belong in scope that the utility model contains.
