Abstract
The utility model discloses a retractable support frame for tarpaulin head covers, which includes a rotary shaft, a plurality of support poles and a plurality of fork-type seats with different widths. The lower end of each support pole is fixed on a fork-type seat, the lower end of the fork-type seat is rotatably arranged on the rotary shaft, and the support poles are arranged in a same longitudinal cross section. The support poles move in the same longitudinal cross section, and are inter-pushed during retraction of the top cover. The tarpaulin is not needed for tensile force transmission, and is thus not easily damaged. Furthermore, order arrangement of the support poles facilitates fixation of the upper tarpaulin, and the tarpaulin is not easily damaged by the shearing force as generated by a pair of scissors. The fork-type seat and the rotary shaft form a frame structure, which is featured with better rigidity, uneasy distortion and deformation and better movement stability.
Description
Technical field
The utility model relates to a kind of tarpaulin top cover, particularly a kind of bracing frame of the telescopic tarpaulin top cover that is made of rotating shaft and Duo Gen support bar.
Background technology
Telescopic tarpaulin top cover is a kind of covering device that is usually used in vehicle or other occasion, and its bracing frame generally is to be made of many support bars that are connected in rotationally in the same rotating shaft, and tarpaulin is fixedly connected on the top and the lateral surface of support bar.A wherein outmost support bar is a driving lever, rotating shaft is with certain drive force driving lever, it is rotated around the axis, driving force (for example spurring with wire rope) can drive other support bar (other support bar can freely rotate around the axis) motion together successively, can realize the flexible of tarpaulin top cover like this.Yet because each support bar is to be connected in successively in the rotating shaft, each support bar is not in same longitudinal section, in the top cover contraction process, the plane of movement difference of each support bar, inconvenience is fixing of tarpaulin thereon, and when support moves, tarpaulin is produced destruction, also have the aesthetic appearance of tarpaulin top cover bad owing to be similar to the shear action of scissors.
The utility model content
The technical problems to be solved in the utility model provides a kind of bracing frame of telescopic tarpaulin top cover, and its each support bar can move in same longitudinal section.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of bracing frame of telescopic tarpaulin top cover, comprise rotating shaft and Duo Gen support bar, also comprise the fork-shaped bearing that a plurality of width are different, the lower end of every support bar is fixed on the fork-shaped bearing, the lower end of fork-shaped bearing is installed in rotation in the rotating shaft, and each support bar is arranged in the same longitudinal section.
Described fork-shaped bearing is formed by being installed in two arc bent plates in the rotating shaft and being connected two tranverse connecting rods between the arc bent plate, and described support bar is fixed on the tranverse connecting rod.
Bracing frame of the present utility model, because its support bar is not directly to be connected in the rotating shaft, but be fixed on the fork-shaped bearing of certain width, each support bar is arranged in the same longitudinal section becomes possibility, each support bar just can move in same longitudinal section like this, can not produce destruction to tarpaulin owing to the shear action that is similar to scissors, simultaneously, because each support bar marshalling, also just tarpaulin fixing thereon.Frame construction is formed in fork-shaped bearing and rotating shaft, and rigidity is better, is difficult for torsional deformation, and the stability of motion is better.
Description of drawings
Fig. 1 is the structural representation of the bracing frame of the telescopic tarpaulin top cover of the utility model.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the schematic diagram of fork-shaped bearing.
The specific embodiment
As shown in Figure 1 and Figure 2, the different fork-shaped bearing 2 of several width is installed in the rotating shaft 3, and can 3 rotate around the shaft, can not produce interference each other; The lower end of support bar 1 is fixed on the fork-shaped bearing 2; The structure of fork-shaped bearing 2 as shown in Figure 3, it is made up of two arc bent plates 21 and a tranverse connecting rod 22, tranverse connecting rod 22 is fixed on the upper end of two arc bent plates 21, two arc bent plates 21 are connected in the rotating shaft 3, support bar 1 is fixed on the tranverse connecting rod 22, and each support bar 1 all is arranged in the same longitudinal section.This structure is convenient to tarpaulin fixing on support bar, can not produce destruction to tarpaulin owing to the shear action that is similar to scissors, also improve the motion and the stress of whole system simultaneously.
