DETAILED DESCRIPTION

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] See also Figure 1-Figure 3The utility model provides a technical solution: a plastic valve body shell, including a plastic valve shell 1, a first arc-shaped clamping plate 7, a second arc-shaped clamping plate 11, a first arc-shaped spring sheet 12 and a second arc-shaped spring sheet 13, the left and right ends of the outer side of the plastic valve shell 1 are sleeved with inner rubber rings 4, the outer sides of the two inner rubber rings 4 are sleeved with outer rubber rings 2 through multiple rubber connecting sheets 5, the gaps between the two outer rubber rings 2 and the two inner rubber rings 4 are filled with multiple sponge buffer layers 3, the multiple sponge buffer layers 3 are provided with clamping grooves 6 on the inner sides relative to the first arc-shaped clamping plate 7 and the second arc-shaped clamping plate 11, and the multiple first arc-shaped clamping plates 7 and the second arc-shaped clamping plates 13 are provided with a plurality of rubber connecting sheets 5. The connecting plates 11 are respectively clamped in the multiple clamping grooves 6, and the multiple first arc-shaped clamping plates 7 are movably connected to the second arc-shaped clamping plates 11 through a micro-reset spring 9. The first pinching pieces 8 are fixed to the right side of the front end of the multiple first arc-shaped clamping plates 7, and the second pinching pieces 10 are fixed to the left side of the front end of the multiple second arc-shaped clamping plates 11. The first arc-shaped spring piece 12 is fixed on the outside of the multiple first arc-shaped clamping plates 7, and the second arc-shaped spring piece 13 is fixed on the outside of the multiple second arc-shaped clamping plates 11. This design solves the problem that the plastic valve shell in the prior art has a single structure and does not have any protective structure. It is easy to be damaged when it is hit by the outside, affecting its actual usability.

[0019] As the first embodiment of the utility model: multiple sponge buffer layers 3 are respectively attached to the side surfaces of multiple rubber connecting sheets 5. Through the added multiple rubber connecting sheets 5, two outer rubber rings 2 can be sleeved outside the two inner rubber rings 4, and a gap is formed between them, so as to facilitate the clamping and installation of multiple sponge buffer layers 3. A valve switch is arranged at the upper end of the plastic valve housing 1, and arc grooves are opened at the upper ends of the two outer rubber rings 2 and the two inner rubber rings 4. The valve switch passes through the arc groove. The added arc groove will not affect the setting of the valve switch.

[0020] The first arc spring piece 12 is attached to the left ends of the first pinching pieces 8, and the second arc spring piece 13 is attached to the right ends of the second pinching pieces 10. The first arc spring piece 12 and the second arc spring piece 13 can be added to compress the two outer rubber rings 2 and the sponge buffer layers 3 when they are partially over-compressed, so as to help alleviate the extrusion. The multiple micro reset springs 9 are all in an extended state. The multiple micro reset springs 9 can push the multiple first arc clamping plates 7 and the multiple second arc clamping plates 11 in opposite directions to ensure that the multiple first arc clamping plates 7 and the multiple second arc clamping plates 11 will not loosen when they are clamped in the multiple clamping grooves 6.

[0021] As the second embodiment of the utility model: in actual use, the two outer rubber rings 2 can protect the outside of the plastic valve housing 1. When it is squeezed or collided in the forward direction, it will transfer the force to the sponge buffer layer 3 for slowing down and absorption. When it is subjected to excessive force and is squeezed excessively, it will contact the first arc-shaped spring piece 12 and the second arc-shaped spring piece 13, so that the first arc-shaped spring piece 12 and the second arc-shaped spring piece 13 can buffer and absorb the force transmitted by them.
