[0002] In today's society, people pay more attention to practicality and functionality in the demand for building space, and the telescopic ceiling as a new type of building design has the advantages of reducing space occupation and wide use scene while meeting people's basic needs. The telescopic ceiling is a new type of ceiling that can be expanded to form a closed or semi-closed space when in use, and can be folded together to achieve light transmission, storage and other effects when not in use. The existing telescopic ceiling, such as the patent application with application number 201910576639.7, proposes a mobile ceiling, which includes a ceiling body, a transmission mechanism and a power mechanism. The ceiling includes a ceiling plate, a load-bearing column fixedly connected with the ceiling plate, and a transmission rail connected with the load-bearing column. The transmission mechanism includes a fixed rail and a transmission chain arranged inside the transmission rail and the fixed rail. The transmission chain is fixed in the transmission rail. The power mechanism is in transmission connection with the transmission chain, and the transmission chain moves in the fixed rail to drive the transmission rail to move relative to the fixed rail. Although this ceiling realizes the telescopic function of the ceiling through the transmission chain, it still has the following shortcomings:

[0003] 1. The chain transmission is prone to tooth drop due to chain loosening in long distance telescopic, and the production cost and use cost of long distance telescopic using chain transmission are relatively high.

[0004] 2. It is difficult to ensure that the ceiling frame is accurately connected with each part during ceiling installation, and there is a lack of components for fine adjustment of the position of the ceiling.

[0005] 3. Chain transmission cannot control the length of the ceiling, and only fixed length chain can be customized to complete the telescopic function of the ceiling, which has limited use scene. CONTENT OF THE UTILITY MODEL

[0029] Please see Figures 1-4 To reduce costs and the probability of malfunctions during telescopic canopy extension and retraction, this embodiment proposes a long-distance telescopic canopy, comprising two parallel trusses 1 connected by a support group 2. The support group 2 includes a drive frame 21, a driven frame 22, and a fixed frame 23. The drive frame 21, driven frame 22, and fixed frame 23 are interconnected by a canopy, which is made of a flexible and bendable material.

The two ends of the fixed frame 23 are fixed to the two trusses 1 on both sides, and the two ends of the drive frame 21 are slidably connected to the two trusses 1 on both sides. Several driven frames 22 are provided between the fixed frame 23 and the drive frame 21, and the two ends of the driven frames 22 are slidably connected to the two trusses 1 on both sides.

[0030] In this embodiment, the drive component 3 can drive the drive frame 21 to slide along the truss 1; the drive component 3 includes a dual-axis motor 31, which is fixed on the drive frame 21; the output shafts on both sides of the dual-axis motor 31 are respectively connected to the drive shaft 32, and the output shafts of the dual-axis motor 31 and the drive shaft 32 are connected by a cross-type universal coupling 33; the end of the drive shaft 32 is connected to a gear 34, and a rack 35 is connected to the corresponding truss 1. The gear 34 and the rack 35 cooperate to drive the drive frame 21 to move along the truss 1.

[0031] Working principle:

[0032] The dual-axis motor 31 drives the transmission shaft 32 and gear 34 to rotate. The gear 34 drives the driving point to move forward or backward on the rack 35, thereby driving the drive frame 21 to move. The drive frame 21 extends the canopy by traction, thereby driving the driven frame 22 to slide forward, so as to achieve the effect of a long-distance telescopic canopy.

[0033] Example 2:

[0034] Continue reading Figures 1-4 The rest is the same as in Embodiment 1, except that: in order to facilitate fine adjustment of the position of the rack 35 to ensure the engagement with the gear 34, the rack 35 in this embodiment is installed on the truss 1 by several connecting components 4; the connecting components 4 include a U-shaped plate, the U-shaped plate includes two side plates 41 and a bottom plate 42, the rack 35 is bolted between the two side plates 41 of the U-shaped plate, and the bottom plate 42 is bolted to the top of the truss 1.

[0035] In this embodiment, a threaded hole is provided on the side of the rack 35, and a guide groove 44 is provided on the corresponding side plate 41. The fixing bolt 47 passes through the guide groove 44 and engages with the threaded hole; the fixing bolt 47 can slide vertically within the guide groove 44. Several balance bolts 45 are provided at the bottom of the rack 35. Several balance nuts 46 that engage with the balance bolts 45 are provided on the bottom truss 1 of the rack 35. Rotating the balance bolts 45 can adjust the vertical position of the rack 35.

Once the adjustment is complete, or the fixing bolts 47 are tightened, the adjustment is finished.

[0036] In this embodiment, in order to improve the fixing reliability of the rack 35, a reinforcing plate 43 is also connected to one side of the bottom plate 42 of the U-shaped plate. The reinforcing plate 43 and the bottom plate 42 form an L-shaped structure, and the reinforcing plate 43 is threaded to the outside of the truss 1.

[0037] Example 3:

[0038] Continue reading Figures 1-4The rest is the same as in Embodiment 1, except that: in order to better guide the direction of extension and retraction and improve the accuracy of installation, the bottom of both ends of the drive frame 21 and the driven frame 22 in this embodiment are connected to longitudinal sliders 38, and the top of the corresponding truss 1 is connected to longitudinal slide rails 39. The longitudinal sliders 38 can slide along the longitudinal slide rails 39 to make the drive frame 21 and the driven frame 22 slide along the truss 1.
