DETAILED DESCRIPTION

[0021] The technical solution of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings and specific embodiments.

[0022] like Figure 1-Figure 5 As shown, the present embodiment provides a PVC background cloth device that is easy to replace, including a support frame 1, on which a replacement adjustment mechanism 2 is provided; the replacement adjustment mechanism 2 includes a fixing frame 3 installed inside the support frame 1, a motor 4 is fixedly installed at the bottom of the fixing frame 3, a cross tray 5 connected to the output end of the motor 4 is provided above the fixing frame 3, a plurality of fixing frames 6 are fixedly installed on the cross tray 5, and a background cloth main body 7 installed by a tape measure spring is provided on the fixing frame 6; a first hydraulic rod 8 is fixedly installed on one side of the support frame 1, and a clamp 9 for fixing the background cloth main body 7 is installed at the output end of the first hydraulic rod 8. By replacing the setting of the adjustment mechanism 2, it is convenient to replace different background cloth bodies 7. Multiple background cloth bodies 7 are fixedly installed on the cross tray 5 through the fixed frame 6. When the background cloth body 7 needs to be replaced, the motor 4 is started to rotate its output end to drive the cross tray 5 to rotate. The rotation of the cross tray 5 can change the position of different background cloth bodies 7. After replacing the position of the required background cloth body 7, the first hydraulic rod 8 is started to extend its output end toward the background cloth body 7, and then the clamp 9 is connected and fixed to the background cloth body 7. Then the first hydraulic rod 8 is started to contract and the background cloth body 7 can be pulled out of the fixed frame 6 and unfolded for use. To replace different background cloth bodies 7, it is only necessary to start the motor 4 to rotate and adjust it. It is very convenient to use and greatly improves the efficiency of shooting.

[0023] The clamp 9 includes a plurality of springs 10 symmetrically mounted on its surface, a support rod 11 movably connected to the clamp 9 is mounted between two adjacent springs 10, and a block 12 is fixedly mounted at one end of the support rod 11; two slots 13 are symmetrically arranged at one end of the background cloth body 7, and the size of the slots 13 matches the block 12; two first magnetic blocks 14 are symmetrically mounted on the surface of the fixed frame 6, and two second magnetic blocks 15 adsorbed mutually with the first magnetic blocks 14 are fixedly mounted at the top and bottom of the background cloth body 7. The clamp 9 and the background cloth body 7 are connected by the engagement of the block 12 and the slot 13, and the block 12 is supported by the spring 10 and can be pulled, so that the connection and separation of the background cloth body 7 and the clamp 9 are more convenient and easy to use; after the background cloth body 7 is rolled up into the fixed frame 6, the first magnetic block 14 and the second magnetic block 15 are mutually attached and adsorbed to fix one end of the background cloth body 7, so as to prevent the background cloth body 7 from being excessively rolled up into the fixed frame 6 and affecting the pulling out.

[0024] A label box 16 is fixedly installed on one side of the fixed frame 6, and an observation window is provided on the label box 16; a soundproof cover 17 fixedly installed on the fixed frame 3 is sleeved on the motor 4, and a heat dissipation hole is opened on the soundproof cover 17; a plurality of second hydraulic rods 18 are fixedly installed at the bottom of the support frame 1, and a moving wheel 19 is installed on the output end of the second hydraulic rod 18. The label box 16 is used to place labels for distinguishing the background cloth body 7, which is convenient for identification during adjustment; the setting of the soundproof cover 17 can reduce the noise of the motor 4, and the opening of the heat dissipation hole facilitates the heat of the motor 4 to be discharged outward; the output end of the second hydraulic rod 18 can extend the moving wheel 19, and the support frame 1 can be moved as a whole by using a plurality of moving wheels 19. When the second hydraulic rod 18 drives the moving wheel 19 to retract, the bottom of the support frame 1 can contact the ground to improve stability.

[0025] The working process of the PVC background cloth device which is easy to replace provided in this embodiment is as follows: a plurality of background cloth bodies 7 are fixedly installed on the cross tray 5 through the fixing frame 6. When the background cloth body 7 needs to be replaced, the motor 4 is started to rotate its output end to drive the cross tray 5 to rotate. The rotation of the cross tray 5 can change the positions of different background cloth bodies 7. After the required position of the background cloth body 7 is replaced, the first hydraulic rod 8 is started to extend its output end toward the background cloth body 7, and then the clamping block 12 on the clamp 9 is engaged with the clamping groove 13 on the background cloth body 7 to connect and fix them. Then the first hydraulic rod 8 is started to contract to pull the background cloth body 7 out of the fixing frame 6 and unfold it for use; the first magnetic block 14 and the second magnetic block 15 are attached to each other to fix one end of the background cloth body 7 to prevent the background cloth body 7 from being excessively rolled up into the fixing frame 6 and affecting the pulling out.
