[0015] Preferably, the material of the adhesive layer is silicone.

[0016] (III) Beneficial effects

[0017] 1. The present invention provides a rat-proof layer. When the silicon core tube is gnawed by mice, the mice will first bite the hollow annular tube body and gnaw from the hollow annular tube body inwards. When the mouse's fangs touch the airbag, the airbag will burst. On the one hand, a loud noise will be emitted at the moment of the airbag bursting, and the sound can scare away the mice. On the other hand, the spring group will rebound instantly at the moment of the airbag bursting, thereby driving the impact plate to impact the mouse's fangs, thereby playing a good role in driving away the mice. Through this dual effect, the mice are well driven away, preventing the mice from continuing to gnaw the silicon core tube inwards, and the silicon core tube is well protected. In addition, the impact plate will eventually resist the place on the hollow annular tube body bitten by the mice, playing a good repairing role. Among them, the rat-proof layer can also play a good shock-absorbing and pressure-resistant effect.

[0018] 2. The present invention can provide a limiting frame to effectively limit the airbag, thereby limiting the airbag in the limiting frame when the airbag is inflated, and can prevent the explosion of one airbag from affecting its adjacent airbags.

[0019] 3. The present invention can replace the exploded airbags in time by providing several groups of spare airbags and impact plates, thereby ensuring the integrity of the entire rat-proofing layer. In addition, if the rats gnaw the bitten areas for the second time, since there are spare airbags on the inner side of the impact plates, the impact plates will be pressed inward when the rats gnaw the impact plates. This makes it inconvenient for the rats to gnaw on the impact plates, and on the other hand, the impact plates will play a certain role in driving away the rats in the process of rebounding after being pressed inwards, thereby playing a good rat-proofing role.

[0020] 4. The present invention arranges the first arc block and the second arc block. At the moment when the airbag explodes, the impact plate will rub and collide with the first arc block and the second arc block in the process of rebounding outwards. This continuous friction and collision will produce a loud noise, which will scare away mice and further enhance the effect of driving away mice. The first arc block and the second arc block are arranged as arc-shaped elastic metal sheets, which not only facilitates the passage of the impact plate, but also produces a louder noise, further enhancing the effect of driving away mice. By staggering the first arc block and the second arc block, on the one hand, it greatly facilitates the outward rebound of the impact plate, and on the other hand, it allows the impact plate to shake left and right in the process of rebounding outwards. In addition, the effect of the spring group greatly enhances the impact force between the impact plate and the first arc block and the second arc block, further enhancing the noise of the impact, thereby further enhancing the effect of driving away mice.

[0021] 5. The present invention provides the impact ball and the third arc block, so that when the impact plate squeezes the first arc block or the second arc block, the impact ball can hit the third arc block, thereby further enhancing the overall sound and ultimately improving the effect of driving away mice.

DETAILED DESCRIPTION

[0034] The following will be combined with the attached embodiment of the present invention Figure 1-11 The technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] The present invention provides a technical solution: a rat-proof silicon core tube, comprising a HDPE tube 1, a silicon core layer 2 is fixed on the inner wall of the HDPE tube 1, a rat-proof layer 3 is fixed on the outer wall of the HDPE tube 1, the rat-proof layer 3 comprises a hollow annular tube body 4 fixed on the outer wall of the HDPE tube 1, a plurality of spring groups 5 are fixed on the inner bottom wall of the hollow annular tube body 4, a strike plate 6 is fixed on the outer end of the spring group 5, an air bag 7 is arranged on the strike plate 6, the upper end of the air bag 7 is against the inner top wall of the hollow annular tube body 4, when the silicon core tube is gnawed by mice, the mice will first bite the hollow annular tube body 4, and then enter the hollow annular tube body 4 from the inner side. When the rat's fangs touch the airbag 7, the airbag 7 will burst. On the one hand, the airbag 7 will make a loud noise at the moment of bursting, which can scare away the rat. On the other hand, the spring group 5 will rebound instantly at the moment of the airbag 7 bursting, and then drive the impact plate 6 to impact the rat's fangs, and then play a good role in driving the rats away. Through this dual effect, the rats are well driven away, preventing the rats from continuing to gnaw the silicon core tube inward, and the silicon core tube is well protected. In addition, the impact plate 6 will eventually resist the place bitten by the rat on the hollow annular tube body 4, which plays a good repairing role. Among them, the rat-proof layer 3 can also play a good shock-absorbing and pressure-resistant effect. Among them, the airbag 7 is filled with gas, and the degree of filling the airbag 7 by the gas in it is just the state that the airbag 7 can burst after the rat's fangs pierce the airbag 7. When the airbag 7 is filled, the spring in the spring group 5 is in a compressed state.

[0036] The airbag 7 is provided with a limit frame 8, and the airbag 7 is arranged in the limit frame 8. The outer end of the limit frame 8 is fixed on the inner top wall of the hollow annular tube 4, and a gap 9 is left between the inner end and the inner bottom wall of the hollow annular tube 4. The setting of the limit frame 8 can play a good limiting role on the airbag 7 on the one hand, and the airbag 7 is limited in the limit frame 8 when the airbag 7 is inflated, and on the other hand, it can prevent an airbag 7 from affecting its adjacent airbags 7 after it explodes. There is a gap 9 between the inner end of the limit frame 8 and the inner bottom wall of the hollow annular tube 4, and the setting of the gap 9 does not affect the expansion and contraction of the spring group 5. The continuously arranged limit frames 8 form a grid shape, which can save materials, and the plate of the limit frame 8 can be set relatively thin, so that the airbag 7 can almost cover the entire hollow annular tube 4, and finally improve the anti-rat effect.

[0037] A plurality of spare airbags 10 are arranged on the inner side of the impact plate 6, and a spare impact plate 11 is fixed on the inner side of each spare airbag 10. Each spare airbag 10 is connected to one end of a connecting pipe 12, and the other end of the connecting pipe 12 passes through the end face of the hollow annular tube body 4, and the connecting pipe 12 part that passes through the end face of the hollow annular tube body 4 is detachably connected with an end cap 13. When one of the airbags 7 is bitten and exploded by a mouse, the spare airbag 10 adjacent to it is inflated until it reaches the state of the exploded airbag 7. When inflating the spare airbag 10, first open the corresponding end cap 13, then connect the connecting pipe 12 through an external air pump, and then inflate it. The part of the hollow annular tube body 4 corresponding to each airbag 7 is marked accordingly, and the part of the connecting pipe 12 corresponding to the airbag 7 extending out of the hollow annular tube body 4 is also marked accordingly, so that it is convenient to find the corresponding connecting pipe 12 when inflating. By setting up several groups of spare airbags 10 and impact plates 11, the exploded airbags 7 can be replaced in time to ensure the integrity of the entire rat-proof layer 3. In addition, if the rats gnaw the bitten area for the second time, since the inner side of the impact plate 6 is the spare airbag 10, when the rats gnaw the impact plate 6, the impact plate 6 will be pressed inwards, which is not convenient for the rats to gnaw, and on the other hand, the process of the impact plate 6 rebounding after being pressed inwards will have a certain effect of driving away the rats, thus playing a good role in rat-proofing. It is most appropriate to set up two groups of spare airbags 10 and spare impact plates 11.

[0038] The limiting frame 8 is composed of a left side plate 14, a right side plate 15, a front side plate and a rear side plate. A plurality of first arc blocks 16 are fixed on the inner wall of the left side plate 14, and a plurality of second arc blocks 17 are fixed on the inner wall of the right side plate 15. Through the arrangement of the first arc blocks 16 and the second arc blocks 17, at the moment when the airbag 7 explodes, the impact plate 6 will rub and collide with the first arc blocks 16 and the second arc blocks 17 in the process of rebounding outwards. This continuous friction and collision will produce a loud noise, which will scare away the mice, further enhancing the effect of driving away the mice.

[0039] The first arc block 16 and the second arc block 17 are configured as arc-shaped elastic metal sheets, wherein the first arc block 16 and the second arc block 17 are configured as arc-shaped elastic metal sheets, which not only facilitates the passage of the impact plate 6, but also generates a louder sound, further improving the effect of driving away mice.

[0040] A plurality of first arc blocks 16 and a plurality of second arc blocks 17 are staggered, that is, the center lines of two adjacent first arc blocks 16 coincide with the center line of a second arc block 17. By staggering the first arc blocks 16 and the second arc blocks 17, on the one hand, it is greatly facilitated for the impact plate 6 to rebound outward, and on the other hand, the impact plate 6 can be made to rebound outward while shaking left and right during the outward rebound process. Coupled with the effect of the spring group 5, the impact force between the impact plate 6 and the first arc block 16 and the second arc block 17 is greatly enhanced, further enhancing the sound of the impact, thereby further enhancing the effect of driving away mice.

[0041] The left and right end faces of the impact plate 6 are both configured as arc-shaped end faces 18 , which can minimize the contact area between the impact plate 6 and the first arc block 16 and the second arc block 17 during the outward rebound process, thereby further facilitating the outward rebound of the impact plate 6 .

[0042] A plurality of impact balls 19 are fixed to the outside of the first arc block 16 and the second arc block 17. A third arc block 20 is provided on the outside of the impact ball 19. A gap is left between the third arc block 20 and the impact ball 19. This arrangement allows the impact ball 19 to hit the third arc block 20 when the impact plate 6 squeezes the first arc block 16 or the second arc block 17, thereby further enhancing the overall sound and ultimately improving the effect of driving away mice.

[0043] An adhesive layer 21 is provided between the HDPE pipe 1 and the silicon core layer 2 , and the adhesive layer 21 is provided to increase the firmness between the HDPE pipe 1 and the silicon core layer 2 .

[0044] The material of the adhesive layer 21 is silicone. The silicone material has good bonding effect and strong flexibility.

[0045] Working principle: When the silicon core tube is being eaten by mice, the mice will first bite the hollow annular tube body 4 and eat from the hollow annular tube body 4 inwards. When the mouse's fangs touch the airbag 7, the airbag 7 will burst. On the one hand, the airbag 7 will make a loud noise at the moment of bursting, which can scare away the mice. On the other hand, the spring group 5 will rebound instantly at the moment of bursting the airbag 7, and then drive the impact plate 6 to hit the mouse's fangs, which will play a good role in driving the mice away. Through this dual effect, the mice are well driven away, preventing the mice from continuing to gnaw the silicon core tube inwards, and the silicon core tube is well protected. In addition, the impact plate 6 will eventually resist the place on the hollow annular tube body 4 bitten by the mouse, which plays a good repairing role. The mouse-proof layer 3 can also play a good shock-absorbing and pressure-resistant effect.
