Abstract
The utility model relates to a door track structure, which consists of a top plate and two side guard plates, wherein the side guard plates are respectively and integrally made at the two ends of the top plate, the bottom end of each side guard plate is inwards bent for forming an edgefold, limiting plates which are in mirror symmetry and are respectively connected with the top plate and the two side guard plates are welded and fixedly arranged in the track, and each limiting plate is made of an elastic steel plate and is used for limiting the moving direction of rollers for preventing the rollers from swinging left and right and falling off from the cracks of the track, so that the rollers can stably operate in the track.
Description
Technical field
The utility model belongs to a field, relates to track, especially a kind of door track structure.
Background technology
Automatic lift gate, with advantages such as its compact conformation, easy for installation, dependable performance, noiselessnesss, is widely used in the places such as garage, industrial premises, warehouse, but this important component part of its track exists defects such as roller easily comes off, strength deficiency.
By retrieval, find following three pieces of patent documentations:
1, a kind of Coiling door track (CN2532224), its section is roughly " ∏ " shape; Track inner side is provided with corresponding two convex tendons, is provided with the cover plate being placed on convex tendon in track, and cover plate and track inside wall form screw installation cavity.
2, a kind of automatic lift gate rail (CN201198709), the both sides of this track are the relative and symmetrical arc slot rolling of opening, are U-shaped kerve between the base of slot rolling, the dual-side of the base of slot rolling and U-shaped kerve seamlessly transits.
3, a kind of rail of rolling door (CN202055726U), described track is U-rail, U-rail edge is provided with weather strip, is embedded with seal weatherstrip on weather strip, seal weatherstrip and door body close contact.
Above-mentioned patent structurally has significantly different from present patent application.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, and the door track structure that a kind of intensity is high, door running body is steady, roller is difficult for deviating from is provided.
The technical scheme that the utility model technical solution problem adopts is:
A kind of door track structure, by top board and two side guard boards, formed, at the two ends of top board, one is made a side guard board vertical with top board respectively, the bottom of each side guard board formation flanging that bends inwards respectively, portion, connects respectively the limiting plate that symmetrical each welding of top board and two side guard board mirror images is fixed with an inclination in orbit.
And described limiting plate is elasticity iron plate.
And one is made a stiffener respectively between side guard board and its flanging, and the stiffener of both sides is mutually tilted respectively.
Advantage of the present utility model and good effect are:
1, this door track portion in orbit, connect respectively the limiting plate that symmetrical each welding of top board and two side guard board mirror images is fixed with an inclination, this limiting plate is made by elasticity iron plate, its effect is the direction of motion of restriction roller, prevent that it from rolling, from the crevice place of track, come off, make its even running in orbit.
2, this door track is improved the shape of traditional automatic lift gate rail, and the shape of track both sides is consistent with structure, has guaranteed that the mechanical strength of track is consistent, makes orbit strength increase, not yielding.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is the right view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing and by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A door track structure, consists of top board 1 and two side guard boards 3, and at the two ends of top board, one is made a side guard board vertical with top board respectively, and the bottom of each side guard board bends inwards respectively, forms flanging 5.
Innovative point of the present utility model is:
Portion, connects respectively the limiting plate 2 that symmetrical each welding of top board and two side guard board mirror images is fixed with an inclination in orbit, and described limiting plate is made by elasticity iron plate, its effect is the direction of motion of restriction roller, prevent that it from rolling, from the crevice place of track, come off, make its even running in orbit.
In order to strengthen the intensity of track, between side guard board and flanging, one is made a stiffener 4 respectively, and the stiffener of both sides is mutually tilted respectively.
Claims (3)
1. a door track structure, it is characterized in that: by top board and two side guard boards, formed, at the two ends of top board, one is made a side guard board vertical with top board respectively, the bottom of each side guard board formation flanging that bends inwards respectively, portion, connects respectively the limiting plate that symmetrical each welding of top board and two side guard board mirror images is fixed with an inclination in orbit.
2. door track structure according to claim 1, is characterized in that: described limiting plate is elasticity iron plate.
3. door track structure according to claim 1, is characterized in that: between side guard board and its flanging, one is made a stiffener respectively, and the stiffener of both sides is mutually tilted respectively.
