The guide rail structure of translation door
Technical field
The present invention relates to guide rail, particularly a kind of guide rail structure of translation door.
Background technology
The existing heavy translation door for garden door, garage door, factory's door etc., its guide rail is all generally triangle rail or the I-shaped rail that angle bar serves as, while using triangle rail, guide rail is easily by draw down, can puncture tire, fixed screw exposes, and gets rusty easily, affects attractive in appearance, while using I-shaped rail, need install at ground fluting, inconvenience is installed, and the interior easily ponding of groove, cause guide rail to get rusty, affect the application life of guide rail.
Summary of the invention
The technical problem to be solved in the present invention, is to provide a kind of guide rail structure of translation door, easy for installation, and good looking appearance uses safety, firm in structure, durable in use.
For solving the problems of the technologies described above, technical scheme of the present invention is: the guide rail structure that a kind of translation door is provided, it comprises bearing assembly, and the top guide rail that is arc surface, bearing assembly is combined up and down by saddle and base, and its overall longitudinal section is trapezoidal, the top of saddle, be provided with the slot extending along its direction of extension, guide rail correspondence is inserted in slot.
The guide rail structure of translation door as above, the centre of base, is provided with the boss extending along its direction of extension, and the top of boss is provided with cutting, and the below, top of saddle, is provided with the A groove extending along saddle direction of extension, cutting grafting corresponding to A groove.
The guide rail structure of translation door as above, the both sides of boss, are all provided with the nail groove and the B groove that extend along base direction of extension successively, two hypotenuse lower ends of saddle, are equipped with vertical pin, two pins respectively with two corresponding grafting of B groove.
The guide rail structure of translation door as above, guide rail is cylinder, slot is circular trough.
Adopt the guide rail structure of the translation door of said structure, owing to can passing through nail groove fixed guide, fixed screw is hidden in bearing assembly, easy for installation, good looking appearance, and meanwhile, integral surface, without sharp protrusion, can not puncture tire, uses safety; And, the corresponding grafting by cutting and A groove, pin with B groove, firm in structure, durable in use.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is the longitudinal section schematic diagram of described embodiment.
Detailed description of the invention
Referring to Fig. 1, a kind of guide rail structure of translation door is provided, it comprises bearing assembly 1, and the top guide rail 2 that is arc surface, and wherein bearing assembly 1 can adopt aluminium alloys to make, and guide rail 2 can adopt stainless steel to make, and is specifically as follows cylinder.Bearing assembly 1 is combined up and down by saddle 3 and base 4, and its overall longitudinal section is trapezoidal, is specifically as follows isosceles trapezoid.The top of saddle 3, is provided with the slot 5 extending along its direction of extension, is specifically as follows the circular trough corresponding with cylindrical guide rail 2, and guide rail 2 correspondences are inserted in slot 5, and when use, translation door is erected on guide rail 2 and is realized and sliding by lower sheave 6.
Referring to Fig. 1, the centre of base 4, is provided with the boss 7 extending along its direction of extension, and the top of boss 7 is provided with cutting 8, and the below, top of saddle 3, is provided with the A groove 9 extending along its direction of extension, cutting 8 grafting corresponding to A groove 9.The both sides of boss 7, be all provided with successively along base 4 direction of extension extend nail groove 10 and B groove 11, two hypotenuse lower ends of saddle 3, be equipped with 12, two pins 12 of vertical pin respectively with two corresponding grafting of B groove 11.
When installation, can directly fix guide rail with setscrew through nail groove 10, easy for installation, setscrew is hidden in bearing assembly 1, does not expose good looking appearance.Integral surface is the arc surface of trapezoidal upper base and guide rail 2, without sharp protrusion, can not puncture tire, uses safety.And, the corresponding grafting by cutting 8 and A groove 9, pin 12 with B groove 11, saddle 3 is connected fastening with base 4, can not get loose, and entirety can be born larger load, very firm, durable in use.
Above-described embodiment is the preferred embodiments of the present invention, and all and the similar structure of the present invention and the equivalence of doing change, and all should belong to protection category of the present invention.
