Abstract
The utility model relates to a plastic steel sliding door in the field of building hardware. The plastic steel sliding door sliding device is mainly composed of a pulley supporting frame, a self-tapping screw, a T-shaped head track bolt, a lock nut, a pulley and a stainless steel slide track. The cross section of the pulley supporting frame is in a shape of C, a longitudinal through groove is arranged on the lower side of the pulley supporting frame, the pulley supporting frame is connected with the lower end of a sliding door sash through the self-tapping screw, the pulley is fixed at the lower end of the pulley supporting frame through the T-shaped head track bolt, the pulley is fixed at the lower end of the pulley supporting frame through the T-shaped head track bolt, and the stainless steel slide track is nested on a plastic steel track in an interference fit mode. The plastic steel sliding door sliding device is simple in construction and easy to achieve, pulley replacing is convenient, a plurality of groups of pulleys can be installed according to the weight of the door sash, and faults are reduced. The stainless steel slide track is low in friction coefficient, the sliding door is smooth in sliding, and the integral use performance of the sliding door is improved.
Description
Technical field
The utility model relates to the slide plastics-steel door in architectural hardware field, particularly a kind of a kind of slide plastics-steel door carriage that can improve the whole functional performance of sliding door, the suitable cunning of push-and-pull.
Background technology
Push-and-pull mobile pulley in the Plastic steel door in the market, no matter be single-sheaved block, common double pulley, or the adjustable double pulley, a common defective is arranged, exactly two groups of pulleys adopt screws directly to be fixed on the push-and-pull door leaf.Increasing along with the architectural opening size, the size that is used for the push-and-pull door leaf of building also continues to increase, two groups of load increases that pulley bears, after the repeated multiple times push-and-pull, the pulley serious wear not smooth, the mobile noise of push-and-pull often occurs and strengthens or can't use at all, to often change pulley on the one hand in the use, waste time and energy, the sliding door kerve aperture that very easily causes after the replacing several times on the other hand connecting pulley becomes big, and the tapping screw tautness descends.
The utility model content
In order to address the above problem, the utility model provides a kind of slide plastics-steel door carriage, can solve the conventional push sliding door roller and change the problem that causes the whole functional performance of sliding door to descend repeatedly.
The scheme that the utility model adopts is:
Described a kind of slide plastics-steel door carriage mainly is made up of pulley support, tapping screw, T connector track bolt, locknut, pulley and stainless steel slide rail, described pulley support cross section is c-shaped, described pulley support downside has vertical groove, be that Open Side Down for described C shape, described pulley support is connected in push-and-pull door leaf lower end by described tapping screw, described pulley is fixed on described pulley support lower end by described T connector track bolt, and described stainless steel slide rail interference fit is nested on the plastic-steel track.Because described pulley is by being bolted to described pulley support, rather than is directly connected in the push-and-pull door leaf, can reduce the direct wearing and tearing to push-and-pull door leaf entity, needn't use tapping screw repeatedly when changing pulley simultaneously, operation is also convenient; Described stainless steel slide rail can stop pulley to the too much wearing and tearing of plastic-steel track in addition, and improve the application life of sliding door greatly.
The beneficial effects of the utility model are:
A kind of slide plastics-steel door carriage simple structure realizes that easily pulley is changed convenient, installs firmly, can many group pulleys be installed according to door leaf weight, reduces fault; Described stainless steel slide rail friction factor is lower, but push-and-pull improves the whole functional performance of sliding door along sliding.
Description of drawings
Further specify below in conjunction with figure of the present utility model:
Fig. 1 is the structural representation of described a kind of slide plastics-steel door carriage;
Fig. 2 is the upward view of described pulley support.
Among the figure, 1. pulley support, 2. tapping screw, 3.T type head track bolt, 4. packing ring, 5. locknut, 6. pulley, 7. stainless steel slide rail.
The specific embodiment
A kind of structural representation of slide plastics-steel door carriage mainly is made up of pulley support (1), tapping screw (2), T connector track bolt (3), locknut (5), pulley (6) and stainless steel slide rail (7) as described in as Fig. 1 being.
The upward view of pulley support as described in as Fig. 2 being, described pulley support (1) cross section is c-shaped, described pulley support (1) downside has vertical groove, be that Open Side Down for described C shape, described pulley support (1) is connected in push-and-pull door leaf lower end by described tapping screw (2), described pulley (6) is fixed on described pulley support (1) lower end by described T connector track bolt (3), and described stainless steel slide rail (7) interference fit is nested on the plastic-steel track.
For ease of installing, described pulley support (1) middle part is provided with the tapping screw installing hole, at described vertical groove position of this installing hole vertical lower to big punching should be arranged.Because described pulley is by being bolted to described pulley support, rather than is directly connected in the push-and-pull door leaf, can reduce the direct wearing and tearing to push-and-pull door leaf entity, needn't use tapping screw repeatedly when changing pulley simultaneously, operation is also convenient; Described stainless steel slide rail can stop pulley to the too much wearing and tearing of plastic-steel track in addition, and improve the application life of sliding door greatly.
Claims (1)
1. slide plastics-steel door carriage, mainly formed by pulley support, tapping screw, T connector track bolt, locknut, pulley and stainless steel slide rail, it is characterized in that: described pulley support (1) cross section is c-shaped, described pulley support (1) downside has vertical groove, described pulley support (1) is connected in push-and-pull door leaf lower end by described tapping screw (2), described pulley (6) is fixed on described pulley support (1) lower end by described T connector track bolt (3), and described stainless steel slide rail (7) interference fit is nested on the plastic-steel track.
