[0026] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] See also Figure 1-8 A foldable temporary exhibition hall comprises a left side panel 1, a right side panel 2 and an upper shell panel 3, all of which are arc-shaped; the left side panel 1 and the right side panel 2 are mirror-symmetrical and placed horizontally on the ground; the upper shell panel 3 is slidably covered on the left side panel 1 and the right side panel 2; a left connecting beam 11 is fixed to the upper end of the left side panel 1; the upper end of the left connecting beam 11 is rotatably connected to the lower ends of a plurality of arc-shaped left keels 12 evenly spaced; a right connecting beam 21 is fixed to the upper end of the right side panel 2; the upper end of the right connecting beam 21 is rotatably connected to a plurality of lower ends of the left keels 12 evenly spaced; The lower end of the arc-shaped right keel 22 is arranged in cooperation with the bone 12; the left keel 12 is hinged to the upper part of the right keel 22; the outer arc surfaces of the left keel 12 and the right keel 22 are both attached to the inner arc surface of the upper shell plate 3; a covering mechanism is arranged in the upper shell plate 3; the covering mechanism can fold the upper shell plate 3 to the outside of the right side plate 2; one end of the folding mechanism is fixed to the left connecting beam 11, and the other end is fixed to the right connecting beam 21; the folding mechanism can pull the left connecting beam 11 and the right connecting beam 21 closer to each other, so that the left side plate 1 and the right side plate 2 are folded inward.

[0028] According to the above, the exhibition hall is in an arc shape as a whole, and the left side panel 1, the right side panel 2 and the upper shell panel 3 are all in an arc shape. The left side panel 1 and the right side panel 2 are placed horizontally on the ground, and the upper shell panel 3 covers the left side panel 1 and the right side panel 2. The left keel 12 on the left side panel 1 and the right keel 22 on the right side panel 2 can be connected to form an arc shape and attached to the inner arc surface of the upper shell panel 3; a cover mechanism is provided in the upper shell panel 3; the cover mechanism can push the upper shell panel 3 toward the right side panel 2 and finally close it outside the right side panel 2. The left connecting beam 11 on the left side panel 1 and the right connecting beam 21 on the right side panel 2 are connected by a folding mechanism, and the left side panel 1 and the right side panel 2 can be folded inward by the folding mechanism, and the left keel 12 and the right keel 22 are folded toward the side at the same time.

[0029] In particular, both sides of the upper shell plate 3 should extend to the outside of the left side plate 1 and the right side plate 2 .

[0030] In particular, the left keel 12 and the right keel 22 are arranged in mirror symmetry.

[0031] In particular, the lower end of the left keel 12 is hinged to the left connecting beam 11; the lower end of the right keel 22 is hinged to the right connecting beam 21. When folded, the left keel 12 and the right keel 22 are folded upward (opposite to the folding direction of the lightweight steel plate 5).

[0032] Furthermore, the cover-folding mechanism includes a plurality of motors 31 fixed at the lower end of the inner arc surface of the upper shell plate 3 and a gear 32 coaxially fixed with the rotating shaft of the motor 31; the motor 31 is arranged close to the left side plate 1; a plurality of first latching teeth 13 cooperating with the gear 32 are evenly fixed on the side of the left keel 12; a plurality of second latching teeth 23 cooperating with the gear 32 are evenly fixed on the side of the right keel 22; the motor 31 drives the gear 32 to rotate when it works, and the gear 32 is engaged with the second latching tooth 23 of the right keel 22 by the first latching tooth 13 of the left keel 12, so as to move the upper shell plate 3 toward the side of the right side plate 2 and fold it on the outside of the right side plate 2.

[0033] According to the above, the left keel 12 is provided with a first latching tooth 13 on the side, and the right keel 22 is provided with a second latching tooth 23 on the side, and the first latching tooth 13 and the second latching tooth 23 can be engaged with the gear 32. In this way, when the motor 31 drives the gear 32 to work, the gear 32 will move along the arc formed by the left keel 12 and the right keel 22, and the first latching tooth 13 of the left keel 12 is engaged with the second latching tooth 23 of the right keel 22, so as to move the upper shell plate 3 toward the side of the right side plate 2, and finally fold it outside the right side plate 2.

[0034] Further, the folding mechanism is an electric hydraulic push rod 4; the electric hydraulic push rod 4 is fixed to the right connecting beam 21, and the piston rod 41 of the electric hydraulic push rod 4 is fixed to the left connecting beam 11. When the electric hydraulic push rod 4 extends the piston rod 41, the left connecting beam 11 and the right connecting beam 21 move away from each other, and the left side plate 1 and the right side plate 2 are spread outward, so that the entire exhibition hall is unfolded; when the electric hydraulic push rod 4 retracts the piston rod 41, the left connecting beam 11 and the right connecting beam 21 move closer to each other, and the left side plate 1 and the right side plate 2 are folded inward, so that the entire exhibition hall is folded.

[0035] Furthermore, it also includes a light steel plate 5; one end of the two light steel plates 5 is hinged to the upper end of the left plate 1 and the upper end of the right plate 2 respectively, and the other ends of the two light steel plates 5 are hinged to each other. The light steel plates 5 are mainly used to improve the strength of the entire exhibition hall to avoid collapse caused by insufficient strength of the exhibition hall.

[0036] Further, a lower baffle plate 6 is fixed to the lower outer side of the right side plate 2. The lower baffle plate 6 is arranged at the lower outer side of the right side plate 2, and can be used to limit the position of the upper shell plate 3 when the upper shell plate 3 is folded, so as to prevent the upper shell plate 3 from colliding with the ground when the cover is closed, causing damage.

[0037] Furthermore, the front and rear end surfaces of the right side plate 2 are respectively provided with a slide groove 24 along the circumferential direction; the front and rear end surfaces of the upper shell plate 3 close to the right side plate 2 are respectively fixed with one end of a support arm 33, and the other end of the support arm 33 is rotatably fixed with a pulley 34; the pulley 34 is sleeved in the slide groove 24 and can slide in the slide groove 24. The slide groove 24 and the pulley 34 are provided mainly to reduce the vibration of the upper shell plate 3 during the movement of the upper shell plate 3 toward the right side plate 2, and to improve the stability and stability during the movement.

[0038] In particular, the width of the slide groove 24 should be slightly larger than the diameter of the pulley 34 .

[0039] Working principle of the present invention:

[0040] See also Figure 1-8 When the temporary exhibition hall is folded, the motor 31 is used to drive the gear 32 to rotate, and the gear 32 passes through the arc track formed by the left keel 12 and the right keel 22, and then the gear 32 cooperates with the first latch 13, the gear 32 cooperates with the second latch 23, and the slide 24 cooperates with the pulley 34, so that the upper shell 3 slides along the right keel 22 to the right side plate 2, and finally the upper shell 3 abuts against the lower baffle 6, completing the folding of the upper shell 3. Then the electric hydraulic push rod 4 is driven to retract the piston rod 41, and under the traction and pulling action, the two lightweight steel plates 5 are folded downward into a V shape, and the left keel 12 and the right keel 22 are folded to the side, thereby realizing the folding of the left side plate 1 and the right side plate 2, completing the folding work of the entire exhibition hall, so as to facilitate subsequent lifting and transportation, and turnover utilization.
