Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0023] As Figure 1 - Figure 2 shown, a road surface control point protection cover with an anti-blocking effect includes a protection plate 1 and a fixing plate 3. The upper surface of the protection plate 1 is snap-connected with the fixing plate 3, and a cover plate 4 is rotatably connected to the middle of the fixing plate 3. A button 5 is snap-connected inside the cover plate 4, and a first spring 6 is arranged outside the button 5. The lower end of the button 5 is snap-connected with an inserting rod 7, and a second spring 8 is arranged outside the rear end of the inserting rod 7. The output end of the inserting rod 7 is snap-connected inside the fixing plate 3, and a sealing ring 17 is fixedly connected to the lower surface of the cover plate 4. Pressing the button 5 compresses the first spring 6 to make the inserting rod 7 retract. After closing the cover plate 4 in the middle of the fixing plate 3, the sealing ring 17 is squeezed to form a sealed space. After releasing the button 5, the second spring 8 expands to drive the inserting rod 7 to be snap-connected in the jack inside the fixing plate 3, so as to achieve the purpose of conveniently fixing the cover plate 4 in the middle of the fixing plate 3, and it can also prevent rainwater from leaking to the control points below.

[0024] As Figure 3 - Figure 4 shown, a water seepage tank 2 is opened on the side surface of the protection plate 1, and a positioning hole 10 is opened on the upper surface of the protection plate 1. The water seepage tank 2 facilitates the diversion of rainwater from above the protection plate 1.

[0025] Furthermore, a positioning rod 9 is fixedly connected to the lower surface of the fixing plate 3, and the positioning rod 9 is snap-connected inside the positioning hole 10. Snap-connecting the positioning rod 9 in the positioning hole 10 on the upper surface of the protection plate 1 plays a role in pre-positioning.

[0026] Furthermore, a fixing groove 12 is formed on the upper surface of the protection plate 1, and a clamping groove 13 is formed inside the protection plate 1. Press the fixing plate 3 to fix the clamping block in the fixing groove 12 inside the protection plate 1.

[0027] Furthermore, a protection net 11 is arranged inside the protection plate 1, and a fixing block 14 is fixedly connected to the side surface of the protection net 11. The protection net 11 is arranged inside the protection plate 1 to prevent sundries from falling into the protection device.

[0028] Furthermore, a movable block 15 is slidably connected inside the fixing block 14, and a third spring 16 is fixedly connected inside the movable block 15. Rotate the protection net 11, and after the third spring 16 expands, the movable block 15 is ejected, so as to conveniently engage the fixing block 14 in the buckle at the end of the clamping groove 13.

[0029] Furthermore, the fixing block 14 is snap-fitted inside the clamping groove 13, and one end of the third spring 16 away from the movable block 15 is fixedly connected to the fixing block 14, preventing the protection net 11 from falling off from the middle of the protection plate 1.

[0030] Working principle: When using the road control point protection cover with anti-blocking effect, first press the button 5 to compress the first spring 6 so that the insertion rod 7 retracts. After closing the cover plate 4 in the middle of the fixing plate 3, the sealing ring 17 is squeezed to form a sealed space. After releasing the button 5, the second spring 8 expands to drive the insertion rod 7 to be snap-fitted in the insertion hole inside the fixing plate 3, so as to conveniently fix the cover plate 4 in the middle of the fixing plate 3, and it can also prevent rainwater from leaking to the control point below. When the protection net 11 is arranged inside the protection plate 1, the fixing block 14 is snap-fitted inside the clamping groove 13. Rotate the protection net 11, and after the third spring 16 expands, the movable block 15 is ejected, so as to conveniently engage the fixing block 14 in the buckle at the end of the clamping groove 13, preventing the protection net 11 from falling off from the middle of the protection plate 1, and playing a role in preventing sundries from falling into the protection device. Snap the positioning rod 9 into the positioning hole 10 on the upper surface of the protection plate 1 to play a pre-positioning role. Press the fixing plate 3 to fix the clamping block in the fixing groove 12 inside the protection plate 1, which is convenient to snap the fixing plate 3 above the protection plate 1, so as to achieve the purpose of protecting the internal control point by blocking sunlight and rainwater. And the rainwater is conveniently diverted from above the protection plate 1 through the water seepage groove 2. This is the working principle of the road control point protection cover with anti-blocking effect.
