Description
Technical field
The utility model relates to a kind of overhead door.
Background technology
At present, in order to improve the sealing effectiveness of door, prevent indoor cold air from leaking, the close together between the bottom of door and ground, but door is in switching process, because ground is uneven, door easily and collision on the ground, is easily damaged in the bottom of door.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of and not only can improve sealing effectiveness, but also can avoid the overhead door with collision on the ground.
The utility model realizes like this, a kind of overhead door, comprise a doorframe and a body, one side of described door body is rotationally connected by least one lifting hinge and described doorframe, described lifting hinge to comprise on one spill spin block and once spill spin block, described upper spill spin block side is installed with an axis of rotation, the lower end of described axis of rotation is provided with one first inclined-plane, described lower spill spin block side offers an opening up and circular hole do not run through, described axis of rotation is located in described circular hole, the inwall of described circular hole and the outer wall clearance sliding fit of described axis of rotation, the bottom of described circular hole is provided with the second inclined-plane of one and described first slopes which match.
Further, described upper spill spin block offers multiple first installing hole.
Further, described lower spill spin block offers multiple second installing hole.
Further, the lower end of described door body is installed with an elastic rubber layer.
Particularly, described first inclined-plane is identical with the angle of horizontal plane, described second inclined-plane and horizontal plane and be 10 ° ~ 80 °.
The overhead door that the utility model provides, the state that first inclined-plane and the second inclined-plane all contact is set to close door state, during door body Unscrew, door body driven rotary axle rotates in circular hole, axis of rotation rotates and moves upward, plane-plane contact between first inclined-plane and the second inclined-plane gradates as a point cantact, contact point helically formula rotation on the contact point on the second inclined-plane on the first inclined-plane, axis of rotation is moved up, door body also moves up simultaneously, reach the object of lever gear door body, avoid Men Tiyu collision on the ground, extend the application life of a body; Owing to promoting, hinge processing is simple easily produces, and cost is low, suitable for large-scale promotion.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical solution of the utility model, be briefly described to the accompanying drawing used required in embodiment below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the schematic diagram of the overhead door that the utility model provides.
Fig. 2 is the schematic diagram promoting hinge in the overhead door that provides of the utility model.
Fig. 3 is the decomposing schematic representation promoting hinge in the overhead door that provides of the utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
As shown in FIG. 1 to 3, a kind of overhead door that the utility model embodiment provides, comprise a doorframe 1 and a body 2, one side of door body 2 is rotationally connected with doorframe 1 by least one lifting hinge 3, promote hinge 3 and to comprise on one spill spin block 31 and once spill spin block 32, upper spill spin block 31 side is installed with an axis of rotation 311, the lower end of axis of rotation 311 is provided with one first inclined-plane 312, lower spill spin block 32 side offers an opening up and circular hole 321 do not run through, axis of rotation 311 is located in circular hole 321, the inwall of circular hole 321 and the outer wall clearance sliding fit of axis of rotation 311, the bottom of circular hole 321 is provided with one and first the second inclined-plane 322 that match, inclined-plane 312.
Particularly, described upper spill spin block 31 offers multiple first installing hole 313, by the first installing hole 313, can rapidly upper spill spin block 31 be installed on a body 2.
Particularly, on described lower spill spin block, 32 offer multiple second installing hole 323, by the second installing hole 323, can be installed on doorframe 1 by lower spill spin block 31 rapidly.
Further, the lower end of described door body 2 is installed with an elastic rubber layer (not shown), and namely elastic rubber layer can avoid the collision between a body 2 and ground, can also reduce the space between a body 2 and ground, plays the effect of sealing.
Particularly, described first inclined-plane 312 and horizontal plane, second inclined-plane 322 is identical with the angle of horizontal plane and be 10 ° ~ 80 °, first inclined-plane 312 and horizontal plane in the utility model, second inclined-plane 322 is preferably 45 ° with the angle of horizontal plane, certain first inclined-plane 312 and the angle number of degrees between the second inclined-plane 322 and horizontal plane are determined by the adjustable height of door body 2, first inclined-plane 312 and the angle number of degrees between the second inclined-plane 322 and horizontal plane little, the aspect ratio of door body 2 liters is lower, first inclined-plane 312 and the angle number of degrees between the second inclined-plane 322 and horizontal plane large, the aspect ratio of door body 2 liters is higher.
The overhead door that the utility model provides, the state that first inclined-plane 312 and the second inclined-plane 322 all contact is set to close door state, during door body 2 Unscrew, door body 2 driven rotary axle 311 rotates in circular hole 321, axis of rotation 311 rotates and moves upward, plane-plane contact between first inclined-plane 312 and the second inclined-plane 322 gradates as a point cantact, contact point helically formula rotation on the contact point on the second inclined-plane 322 on the first inclined-plane 312, axis of rotation 311 is moved up, door body 2 also moves up simultaneously, reach the object of lever gear door body 2, avoid a body 2 and collision on the ground, extend the application life of a body 2, process simple easily production owing to promoting hinge 3, cost is low, suitable for large-scale promotion.
The above is preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
