DETAILED DESCRIPTION

[0027] The following describes the implementation of the present invention through specific embodiments. Those skilled in the art can readily understand the other advantages and benefits of the present invention from the contents disclosed in this specification. Obviously, the embodiments described are only a portion of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0028] Refer to the instruction manual Figure 1-5The utility model provides an impact-resistant pump head, including a pump head body, which includes a pressing head 10, a liquid tube 11 and a bottle cap 12 with an internal thread. The pressing head 10 is arranged on the top of the liquid tube 11, and the bottle cap 12 is sleeved on the outside of the liquid tube 11, and the pressing head 10 is arranged on the top of the bottle cap 12; the adjusting ring 1 is sleeved on the outside of the top of the bottle cap 12, and the pressing head 10 is arranged inside the adjusting ring 1, and two clamping plates 4 are respectively installed on the top of both ends of the bottle cap 12, and the bottle cap 12 is sleeved on the outside of the corresponding product, and then the liquid is taken out by the cooperation of the pressing head 10 and the liquid tube 11. The outside of the pump head body is provided with a functional part for enhancing protection;

[0029] like Figure 1 、 3 As shown in , 4 and 5, the functional parts include an adjusting ring 1 which is sleeved on the outside of the pump head body, pressure holes 2 are provided on the bottom of both sides of the adjusting ring 1, and clamping holes 3 are provided on the bottom of the front and rear sides of the adjusting ring 1. The height of the clamping hole 3 is less than the height of the pressure hole 2, and a clamping plate 4 is provided inside the clamping hole 3; a fixing column 5 is installed on the top of the end where the two clamping plates 4 are close to each other, and a spring 6 is sleeved on the outside of the top of the fixing column 5, and a connecting bracket 7 sleeved on the outside of the fixing column 5 is provided at the bottom of the spring 6, and a fixing plate 8 is installed on the top of the end of the connecting bracket 7 away from the fixing column 5; an assembly ring 9 is provided inside the top of the adjusting ring 1, and the fixing plate 8 is installed on the side of the assembly ring 9 close to the connecting bracket 7, and a connecting piece is provided between the assembly ring 9 and the adjusting ring 1.

[0030] Because the adjusting ring 1 and the assembly ring 9 are movably connected through the connecting ring 13 and the connecting ring groove 14, the adjusting ring 1 can rotate around the assembly ring 9. In this way, the staff can lift the adjusting ring 1 to separate the clamping hole 3 from the clamping plate 4, so that the adjusting ring 1 is not restricted and the pressing hole 2 is easily rotated to the clamping plate 4. Since the height of the pressing hole 2 is greater than the clamping plate 4, the downward movement distance of the adjusting ring 1 is longer, so that the adjusting ring 1 can move downward together with the pressing head 10 when pressing downward;

[0031] When the card hole 3 on the adjusting ring 1 is engaged with the card plate 4, the adjusting ring 1 cannot move downward and limits the pressing head 10, which can prevent the pressing head 10 from being pressed downward by external force. The set of the adjusting ring 1 and the shielding of the baffle 17 can provide multi-directional protection for the pressing head 10, avoiding damage to the pressing head 10 caused by external impact, ensuring the performance of the pressing head 10, and at the same time, with the help of the rebound force of the spring 6, the connecting bracket 7 is driven downward, and the connecting bracket 7 then drives the adjusting ring 1 downward through the assembly ring 9, so as to ensure the tightness of the card plate 4 and the card hole 3.

[0032] To facilitate the operation, the adjusting ring 1 is rotated. Figure 4 and 5As shown, the connecting piece includes a connecting ring 13, which is sleeved on the outside of the assembly ring 9, and a connecting ring groove 14 is provided on the side of the adjusting ring 1 corresponding to the connecting ring 13, and the connecting ring 13 is arranged inside the connecting ring groove 14. By the movable engagement of the connecting ring 13 and the connecting ring groove 14, the adjusting ring 1 can be movably connected to the connecting ring 13, thereby achieving the effect of convenient rotation of the adjusting ring 1. Because the cross-section of the connecting ring 13 and the cross-section of the connecting ring groove 14 are both set to T-shape, and the outside of the connecting ring 13 is in contact with the inner wall of the connecting ring groove 14, the connecting ring groove 14 can limit the connecting ring 13 to avoid the connecting ring 13 from separating from the adjusting ring 1, thereby ensuring the stability of the connecting ring 13 during rotation.

[0033] To improve the protection of the pressing head 10, as Figure 1 、 3 As shown in Figure 4, a packaging ring 15 is installed on the top of the adjusting ring 1, and the packaging ring 15 is sleeved on the outside of the bottom end of the pressing head 10. The packaging ring 15 is used to shield and protect the top of the adjusting ring 1, so that the connection between the pressing head 10 and the liquid pipe 11 can be shielded to avoid damage to the pressing head 10 caused by collision and impact.

[0034] To improve the stability of the operating adjustment ring 1, as Figure 1 and 3 As shown, an anti-slip ring 16 is provided on the outside of the packaging ring 15 for stabilizing the rotation of the adjustment ring 1. By connecting the anti-slip ring 16 with the packaging ring 15, the friction between the staff's hand and the adjustment ring 1 can be enhanced, thereby enhancing the stability of the staff in operating the adjustment ring 1.

[0035] To avoid damage to the pressing head 10 caused by impact, Figure 1 、 3 As shown in Figure 4, a baffle 17 is provided on the top of the pressing head 10, and two spaced support columns 18 are installed at the bottom of one end of the baffle 17, and the bottom end of the support column 18 is fixed to the top of the packaging ring 15. By connecting the support column 18 with the packaging ring 15, the supporting strength of the support column 18 can be enhanced, thereby ensuring the stability of the support column 18 fixing the baffle 17.

[0036] In order to ensure the movement stability of spring 6, as Figure 5 As shown, a limit plate 19 is installed on the top of the fixed column 5. The limit plate 19 is arranged on the top of the spring 6, and the diameter of the limit plate 19 is larger than the outer diameter of the spring 6. The top of the spring 6 is limited by the limit plate 19, so as to prevent the spring 6 from separating from the fixed column 5 during the extension and contraction process, thereby effectively ensuring the stability of the spring 6 during movement.

[0037] Although the present invention has been described in detail above using general descriptions and specific embodiments, it will be apparent to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, such modifications or improvements, without departing from the spirit of the present invention, are within the scope of protection claimed herein.
