[0033] See also Figure 1-5 The utility model provides a detachable splicing screen based on back fixing, including:

[0034] The screen 1 has guide grooves 8 on both upper and lower sides of its back;

[0035] A fixing base 2 is arranged at one side of the back of the screen 1, and the fixing base 2 is connected to the installation position of the screen 1. Swingable support rods are arranged on both sides of the fixing base 2. The support rods are divided into an upper support rod 3 and a lower support rod 4 through different upper and lower positions. The upper support rod 3 and the lower support rod 4 are symmetrically arranged up and down;

[0036] A connecting column 6 extends from the upper supporting rod 3 and the lower supporting rod 4 to one end of the screen 1 and extends into the guide groove 8 and is fixedly connected to the upper supporting rod 3 and the lower supporting rod 4 respectively;

[0037] The adsorption seat 10 is installed at the installation position of the screen 1 to form adsorption of the screen 1 , and two one-way valves 14 of different sizes are arranged inside the adsorption seat 10 , and the one-way valves 14 are used to delay the adsorption of the screen 1 .

[0038] In this embodiment, when the screen 1 is installed, the connecting column 6 is inserted into the guide groove 8. Sliding to change the position of the guide groove 8 can control the position of the screen 1, thereby changing the position of the screen 1. When the screen 1 needs to be removed, it is only necessary to separate the connecting column 6 from the guide groove 8.

[0039] In one embodiment, reinforcing ribs 5 are disposed on the outer sides of the upper supporting rod 3 and the lower supporting rod 4, and the reinforcing ribs 5 of the upper supporting rod 3 and the lower supporting rod 4 are symmetrically disposed.

[0040] In this embodiment, the provision of the reinforcing ribs 5 can ensure the strength of the supporting upper rod 3 and the supporting lower rod 4.

[0041] In one embodiment, a rotatable elastic roller 7 is sleeved on the outer side of the connecting column 6 , and the elastic roller 7 is located inside the guide groove 8 and can be squeezed.

[0042] In this embodiment, the elastic roller 7 is not only capable of rotating, but also capable of increasing the friction force when leaving the guide groove 8 by squeezing.

[0043] In one embodiment, the guide groove 8 is opened at an angle, extending from both sides of the screen 1 to the middle of the screen 1 and reducing the height of the guide groove 8 .

[0044] In this embodiment, the obliquely opened guide groove 8 can be squeezed when the elastic roller 7 escapes from the guide groove 8 , thereby preventing the elastic roller 7 from directly escaping from the guide groove 8 and causing the screen 1 to fall when the screen 1 is not stable.

[0045] In one embodiment, a swingably adjustable positioning piece 9 is provided on the top of the screen 1 , and the positioning piece 9 contacts the supporting upper rod 3 to limit the supporting upper rod 3 .

[0046] In this embodiment, the positioning piece 9 provided on the screen 1 can stably support the upper support rod 3, limit the position of the upper support rod 3, and ensure the stability of the upper support rod 3. Since the screen 1 still needs to be regularly maintained and inspected after removal, using the positioning piece 9 to limit the position of the upper support rod 3 can ensure the stability of the position of the screen 1.

[0047] In one embodiment, the interior of the adsorption seat 10 is hollow and filled with hydraulic oil, and a magnetic plate 13 and a traction block 12 are respectively arranged on both sides of the adsorption seat 10 . The magnetic plate 13 magnetically attracts and contacts the screen 1 , and the traction block 12 is pulled to control the position of the magnetic plate 13 .

[0048] In this embodiment, the filling of hydraulic oil can facilitate the synchronous control of the magnetic plate 13 and the traction block 12, so that after the traction block 12 is pulled, the magnetic plate 13 can be separated from the magnetic attraction with the screen 1, so that the screen 1 can be removed easily.

[0049] In one embodiment, a clamping plate 11 is provided on the back of the screen 1, the clamping plate 11 contacts the traction block 12, the screen 1 is pressed through the clamping plate 11 to control the position of the traction block 12, and the one-way valve 14 is located inside the adsorption seat 10 to control the flow of hydraulic oil.

[0050] In this embodiment, the one-way valve 14 has two flow rates, one large and one small, and the connection directions of the two one-way valves 14 are opposite. The one-way valve 14 that enters from the position of the magnetic plate 13 to the position of the traction block 12 is set with a large flow rate, and the one-way valve 14 that flows from the position of the traction block 12 to the position of the magnetic plate 13 is set with a small flow rate. When in use, the traction block 12 is pushed by the clamping plate 11, and the hydraulic oil enters the position of the traction block 12 from the large flow one-way valve 14. When resetting, the small flow one-way valve 14 can extend the resetting time of the magnetic plate 13.

[0051] The traction block 12 needs to be able to automatically reset after being pushed, so a traction spring is provided at one end of the traction block 12 located inside the adsorption seat 10, and when the traction block 12 is reset, it is reset by the traction of the traction spring.

[0052] In one embodiment, an elastic member 15 is disposed on the back of the screen 1 , and the elastic member 15 forms support for the screen 1 .

[0053] In this embodiment, an elastic member 15 is provided to form a support for the screen 1. After the screen 1 is separated from the magnetic plate 13, it can be ejected outward with the support of the elastic member 15, thereby controlling the position of the screen 1 and allowing the screen 1 to be separated from the combined state with other screens 1, making it easier to pull the screen 1 out.
