A coil spring 13 is fixedly installed on the inner wall of the winding drum 11 and the outer wall of the support column 12. A fiber cloth 9 is wound around the outer wall of the winding drum 11, and an inlet and outlet 10 is opened on one side of the first housing 1. One end of the fiber cloth 9 passes through the inlet and outlet 10 and is fixedly connected to the second housing 3. A thin [unclear] is installed on one end of the outer wall of the fiber cloth 9. The iron sheet 19, with one end of the thin iron sheet 19 fixedly installed on the outer wall of the take-up and unwinding drum 11, is wound around the outer wall of the take-up and unwinding drum 11. Anti-detachment rings 14 are fixed at the top and bottom of the outer wall of the take-up and unwinding drum 11, and the fiber cloth 9 is located between the two anti-detachment rings 14. Through the combined design of the take-up and unwinding drum 11, the coil spring 13 and the fiber cloth 9, the fiber cloth 9 can be easily pulled out from the first housing 1 when in use, and can be automatically retracted by the action of the coil spring 13 when not in use, so as to realize the quick unfolding and storage of the baffle, the adjustment operation is simple and the space is saved.

[0039] A braking assembly 2 is provided on the top of the winding drum 11 and the top of the first housing 1. The braking assembly 2 includes a fixed cylinder 201 installed on the top of the first housing 1, and a threaded post 203 is rotatably connected to the middle position of the fixed cylinder 201. A knob 202 is fixed to the top of the threaded post 203, and a lifting frame 204 is screwed to the outer wall of the threaded post 203. The bottom of the fixed cylinder 201 and the top of the first housing 1 have equally spaced openings 207, and the bottom of the lifting frame 204 has connecting frames 205 that pass through the openings 207 at equal intervals. A brake disc 206 is fixed to the top of the 1, and brake grooves 208 are provided at equal intervals in a ring at the bottom corner of the brake disc 206. Brake pins 209 inserted into the brake grooves 208 are fixed to the bottom of the connecting frame 205. The brake assembly 2 can effectively fix and release the winding drum 11, realize the stability of the fiber cloth 9 when unfolding and storing, and form effective fixing performance when the fiber cloth 9 is pulled to a certain length, so that the fiber cloth 9 can be fixed in the required position, which makes it easy to adjust the restriction range of the entire baffle to meet the needs of the field.

[0040] The outer walls of the first housing 1 and the second housing 3 are provided with clamping assemblies. The clamping assemblies include clamp brackets 6 fixedly installed on both sides of the outer wall of the first housing 1, and a connecting seat 5 fixed on one side of the second housing 3. Both sides of the connecting seat 5 are provided with connecting grooves 18. Connecting blocks 16 slide on the inner walls of the connecting grooves 18. Springs 17 are installed at the bottom of the connecting blocks 16 and the bottom of the connecting grooves 18. The same handle bracket 4 is fixed on one side of the two connecting blocks 16, and the two ends of the handle bracket 4 are respectively clamped into the two clamp brackets 6. The handle bracket 4 drives the connecting blocks 16 to slide in the connecting grooves 18, so that the two ends of the handle bracket 4 are clamped and disengaged from the clamp brackets 6, realizing the quick connection and separation of the first housing 1 and the second housing 3, which facilitates the assembly and disassembly of the baffle, and makes it convenient for handling and storage.

[0041] To ensure a smoother unfolding and retraction process for fiber cloth 9, refer to... Figure 4 Two guide rods 15 are rotatably connected to the inner wall of the first housing 1 near the inlet / outlet 10. The two guide rods 15 are respectively movable on both sides of the fiber cloth 9. The guide rods 15 guide the opening and closing of the fiber cloth 9, making the fiber cloth 9 move more smoothly and less prone to problems such as tangling or deviation, thus extending the service life of the fiber cloth 9.

[0042] For ease of movement, refer to Figure 1 and Figure 2 The outer wall near the bottom of the first housing 1 and the outer wall near the bottom of the second housing 3 are both fixedly installed with bases 7, and the bottom of each base 7 is equipped with multiple casters 8, so that the entire ping-pong ball telescopic baffle can be easily moved on indoor and outdoor ground, and the position of the baffle can be adjusted as needed to adapt to different venues and usage scenarios.

[0043] To improve the service life of the entire telescopic baffle, refer to Figure 2 , Figure 3 and Figure 8 The fiber cloth 9 is made of Oxford cloth, and the coil spring 13 and the thin iron sheet 19 are made of carbon steel elastic material. The fiber cloth 9 made of Oxford cloth has the advantages of high strength, wear resistance and waterproofness, and can adapt to various collisions and frictions in table tennis. The coil spring 13 and the thin iron sheet 19 made of carbon steel elastic material have good elasticity and strength, ensuring the normal operation of the coil spring 13 and the fixing effect of the thin iron sheet 19 on the fiber cloth 9.

[0044] Working principle: When it is necessary to move the entire baffle, the position can be adjusted by carrying the entire baffle with the handle 4, or the entire baffle can be pushed to the designated position directly by using the casters 8.

[0045] When the entire baffle needs to be unfolded, the height of the handle bracket 4 inside the clamping assembly is lowered, so that the two ends of the handle bracket 4 are disengaged from the clamp bracket 6. The knob 202 inside the braking assembly 2 drives the threaded column 203 to rotate, lowering the height of the lifting frame 204, connecting frame 205 and brake pin 209, so that the brake pin 209 is disengaged from the brake groove 208 on the brake disc 206. Then, the second housing 3 is moved by pulling the handle bracket 4. At this time, the fiber cloth 9 will be pulled out from the inlet and outlet 10 of the first housing 1, so that the fiber cloth 9 forms an unwinding phenomenon, driving the take-up and unwinding drum 11 and the brake disc 206 to rotate, so that the coil spring 13 is compressed and stores elastic potential energy. When the fiber cloth 9 is stretched to the required length, the knob 202 inside the braking assembly 2 drives the threaded column 203 to reverse, driving the lifting frame 204, connecting frame 205 and brake pin 209 to rise, so that the brake pin 209 is inserted into the brake groove 208, restricting the rotation of the brake disc 206, thereby fixing the take-up and unwinding drum 11 and preventing the fiber cloth 9 from shrinking back.

[0046] After use, the brake pin 209 continues to descend and then rise under the action of the brake assembly 2. During the descent, the brake disc 206 is unlocked, and the elastic restoring force of the coil spring 13 is used to rewind the fiber cloth 9 onto the unwinding drum 11, so as to realize the automatic retraction of the fiber cloth 9. During the rise, the brake disc 206 is restricted, and a locking function is formed after the fiber cloth 9 is fully retracted.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
