Abstract
The utility model discloses a sliding-rail mechanism comprising sliding wheels which are fixed on a rail and can slide on the rail; the sliding wheels are arranged on a sliding-wheel piece which is arranged on a sliding-wheel bracket, wherein a groove is respectively arranged on two side walls of the rail; the lower part of the sliding-wheel piece is used for fixing two side walls of the sliding wheels and extends toward the internal part of the groove to form a projection part which is fastened in the groove. The sliding-wheel bracket is a hollow pipe and an installation arm at the back of the sliding-wheel piece is arranged inside the hollow pipe. The sliding-wheel piece is fixed on the hollow pipe by leading a sliding-wheel localizing core to penetrate the hollow pipe and the sliding-wheel piece. The lower part of the sliding-wheel piece is used for fixing two side walls of the sliding wheels and extends toward the internal part of the groove to form a projection part which is fastened in the groove, and then the possibility that the sliding wheels move upward can be limited, thus avoiding upward derailment of the sliding wheels and ensuring safety.
Description
Technical field
The utility model relates to sliding track mechanism, relates in particular to the sliding track mechanism that portable garage uses.
Background technology
Portable garage in the market, track adopt directed orbit determination, and pulley slides on track.Though track has limited the side-to-side movement of pulley, pulley can only be moved along track, the but possibility that moves upward of pulley without limits, so the situation of track still can appear upwards breaking away from pulley, safety still is difficult to ensure.
The utility model content
Technical problem to be solved in the utility model just provides a kind of sliding track mechanism, can prevent that limited slip wheel upwards breaks away from track, improves the reliability and the safety of sliding track mechanism work.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of sliding track mechanism, comprise fixing track and the pulley that slides in orbit, pulley is located at pulley spare, pulley spare is installed on the pulley bracket, it is characterized in that: described track two side is provided with groove, and the two side of pulley spare bottom fixed block extends to form projection in groove, and described projection is fastened in the groove.
As preferably, described track cross section top and pulley contact site are arcwall face, and this arcwall face middle part projection is the arc top, bilateral symmetry, and the pulley cross section is that the hyperbolic wire realization of medial recess cooperates with track.Make the sliding track mechanism operation more steady.
As preferably, described pulley bracket is a hollow section, and the hold-down arm at pulley spare rear portion is located in the hollow section.Simple in structure, be easy to realize.
As improvement, described pulley spare is sheet or the hollow tubular that cooperates with pulley bracket.Hollow tubular pulley spare is suitable for bearing occasion more energetically, and that sheet is suitable for is stressed less, and pulley bracket is the occasion of flat hollow section.
As preferably, described pulley spare runs through hollow section by pulley location core and pulley spare is fixed in pulley spare on the hollow section.
The utility model is owing to adopted technique scheme, the two side of pulley spare bottom fixed block in groove, extend to form projection be fastened on limited in the groove that pulley moves upward may, the situation of track just can not appear upwards breaking away from pulley like this, and safety is ensured.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further described:
Fig. 1 is the structural representation of the utility model embodiment 1;
Fig. 2 is the structural representation of the utility model embodiment 2;
The specific embodiment
As shown in Figure 1, preferred embodiment for a kind of sliding track mechanism of the utility model, comprise fixing track 1 and the pulley 2 that slides in orbit, pulley is located on the pulley spare 3, pulley spare is installed on the pulley bracket 5, described track two side is provided with groove 11, and the two side 32 of pulley spare bottom fixed block extends to form projection 33 in groove, and described protruding 33 are fastened in the groove 32.Described track cross section top and pulley contact site are arcwall face, and this arcwall face middle part projection is the arc top, bilateral symmetry, and the pulley cross section is that the hyperbolic wire of medial recess realizes cooperating with track.Described pulley bracket 5 is a hollow section, and the hold-down arm 31 at pulley spare rear portion is located in the hollow section.Pulley spare is the sheet that cooperates with flat hollow section pulley bracket, and described pulley spare 3 runs through hollow section by pulley location core 4 and pulley spare is fixed in pulley spare on the hollow section.
As shown in Figure 2, be another embodiment of a kind of sliding track mechanism of the utility model, pulley spare is the square hollow shape that cooperates with the pulley bracket of square hollow.Other structures are identical with embodiment 1.
