Abstract

This utility model discloses an anti-shaking upward rotating vertical downward pressing mechanism, relating to the field of air gun assembly and debugging technology. It includes a base and a pressing block, with the pressing block inserted into the upper end of the base. Guide components for assisting the vertical lifting and lowering of the pressing block are installed on both the base and the pressing block. This utility model improves assembly efficiency through the cooperation of the base and the pressing block, thereby achieving a preliminary lateral limiting function at the bottom of the pressing block. Furthermore, the sliding contact between the two sides of the pressing block and the inner side of the first limiting plate improves the stability of the pressing block during lifting and lowering, thereby achieving a secondary limiting function in the horizontal direction.

Ultimately, this solves the problem of assembly accuracy errors or debugging inconvenience caused by the shaking of the upward rotating pressing block during air gun assembly and debugging.

Description

Instruction Manual 1 A Shaking-Proof Upward Rotation Vertical Downward Pressing Mechanism Technical Field This utility model relates to the field of air gun assembly and debugging technology, and particularly to a shaking-proof upward rotation vertical downward pressing mechanism. Background Art In the assembly and debugging process of air guns, the upward rotation pressing block, as a core functional component, directly affects the overall performance and reliability of the air gun in terms of its installation accuracy and movement stability. However, in the existing air gun assembly system, there are obvious defects in the design of the limiting structure for the upward rotation pressing block, leading to many technical difficulties in the assembly and debugging process. Traditional upward rotation pressing blocks lack effective horizontal limiting constraints during the lifting and lowering movement, causing the contact surface where the upward rotation rubber and BB pellets rub against each other to be skewed, which easily leads to problems such as left and right deviation of the trajectory and shaking. This shaking will directly lead to an increase in assembly accuracy error, making it difficult for the key performance parameters of the air gun (such as shooting accuracy) to meet the design standards. The instability of the pressing point structure, due to the serious instability of the above-mentioned traditional upward rotation pressing point structure and the high requirements for the player's assembly and debugging skills, makes the pursuit of a stable trajectory a luxury for novice players. Therefore, it is necessary to improve the above problems. The purpose of this utility model is to address the shortcomings of existing technologies by proposing an anti-shaking upward rotating and vertically pressing mechanism. To achieve the above objective, this utility model adopts the following technical solution: An anti-shaking upward rotating and vertically pressing mechanism, comprising a base and a pressing block, wherein the pressing block is inserted into the upper end of the base, and a guide assembly for assisting the vertical lifting and lowering of the pressing block is installed on the base and the pressing block. Preferably, the guide assembly includes two first limiting plates and a second limiting plate installed at the top of the base, and guide plates are installed on both sides of the pressing block. Preferably, a guide groove is formed at the top of the base, the lower end of the pressing block is inserted into the guide groove, and the guide groove is located between the two first limiting plates. Preferably, the rear end face of the guide plate slides against the front end face of the first limiting plate, and the inner side face of the guide plate slides against one side of the second limiting plate. Preferably, both sides of the pressing block slide against the inner sides of the two first limiting plates respectively.Compared with the prior art, the beneficial effects of this utility model are as follows: The cooperation between the base and the lower pressure block facilitates quick positioning and installation of the lower pressure block, improving assembly efficiency and enabling the initial lateral limiting function of the lower pressure block's bottom. Furthermore, the sliding contact between the lower pressure block's two sides and the inner side of the first limiting plate restricts the left and right movement of the lower pressure block in the horizontal direction, improving stability during the lifting and lowering process and enabling a secondary limiting function in the horizontal direction. Additionally, the multi-faceted sliding contact between the guide plate and the first and second limiting plates helps to counteract the swaying tendency of the lower pressure block during lifting and lowering, improving the accuracy of the lower pressure block's vertical movement and enabling a multi-dimensional precise limiting function for the lower pressure block. Ultimately, this solves the problem of assembly accuracy errors or inconvenient debugging caused by the shaking of the upper pressure block during air gun assembly and debugging.

Detailed Description of the Embodiments The technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments.Example: Referring to Figures 1 to 4, the anti-shaking upward-spinning vertical downward-pressing mechanism of this utility model includes a base 1 and a pressing block 2. The pressing block 2 is inserted into the upper end of the base 1 (pressing down the upward-spinning rubber, allowing the friction surface of the inner side of the rubber to contact the BB pellet and generate upward-spinning force to move vertically up and down. The friction force generated by the downward pressure is controlled by adjusting the up and down, thereby affecting the upward-spinning force of the BB pellet. The greater the downward pressure, the greater the friction force generated by the rubber, the greater the upward-spinning force of the BB pellet, and the longer the trajectory range. However, excessive upward spin will cause the BB pellet trajectory to be biased upward. Therefore, it is necessary to adjust the upward-spinning force of the BB pellet by moving the pressing block 2 vertically up and down to achieve the straightest and longest range). The base 1 and the pressing block 2 are equipped with a guide component to assist the vertical lifting and lowering of the pressing block 2. The guide component ensures that the pressing block 2 descends vertically without shaking or tilting, providing better and more stable trajectory performance. At the same time, the disassembly and assembly are simple and quick. The guide component includes components installed on the base 1. The top has two first limiting plates 4 and a second limiting plate 6 (HK 30134884 A Instruction Manual 4). The first limiting plates 4 and the second limiting plates 6 can limit the guide plate 5 in both the X and Y axes, ensuring that the guide plate 5 will not wobble when it rises and falls. Guide plates 5 are installed on both sides of the lower pressure block 2. Through the connection between the guide plates 5 and the lower pressure block 2, the lower pressure block 2 is also driven to rise and fall vertically. The top of the base 1 has a guide groove 3, which guides the lower pressure block 2. At the same time, in conjunction with the first limiting plates 4 and the second limiting plates 6, the lower pressure block 2 can be limited in four directions, which is conducive to the player's quick assembly and disassembly adjustment of the trajectory. The lower end of the lower pressure block 2 is inserted into the guide groove 3, and the guide groove 3 is located between the two first limiting plates 4. In this utility model, the rear end face of the guide plate 5 slides against the front end face of the first limiting plate 4, the inner side of the guide plate 5 slides against one side of the second limiting plate 6, and the two sides of the lower pressing block 2 slide against the inner sides of the two first limiting plates 4 respectively. Due to the sliding contact between the guide plate 5 and the first limiting plate 4 and the second limiting plate 6, the guide plate 5 fits more tightly with the two, thereby eliminating the space for the lower pressing block 2 to wobble and improving the stability of the lower pressing block 2 during installation.Working principle: When using this utility model, first align the lower end of the pressing block 2 with the guide groove 3 at the top of the base 1, and then insert the pressing block 2 vertically downward into the guide groove 3 (the guide groove 3 is located between the two first limiting plates 4) to complete the initial assembly; at this time, the guide plates 5 on both sides of the pressing block 2 will slide against the inner sides of the two first limiting plates 4 respectively, and at the same time, the rear end face of the guide plate 5 will slide against the front end face of the first limiting plate 4, and the inner side face of the guide plate 5 will slide against one side of the second limiting plate 6. Since the guide plate 5 is in tight sliding contact with the first limiting plate 4 and the second limiting plate 6, there is no space for the guide plate 5 to wobble, which in turn restricts the space for the pressing block 2 to wobble; during the subsequent lifting and lowering process of the pressing block HK 30134884 A instruction manual 5 2, the first limiting plate 4 will limit the pressing block 2 and the guide plate 5 in one direction of the horizontal X-axis, and the second limiting plate 6 The guide plate 5 is limited in another direction along the horizontal X-axis, while the guide groove 3 on the base 1 constrains the lower end of the pressure block 2. Through the guiding action of the guide groove 3 and the coordinated limiting action of the first limiting plate 4 and the second limiting plate 6, the pressure block 2 is fully limited in four directions, ensuring that the pressure block 2 can always maintain stable vertical lifting and lowering, effectively preventing shaking or tilting. When disassembly and adjustment are required, the pressure block 2 can be disassembled simply by pulling it vertically upward out of the guide groove 3. The entire process does not require complicated tools and can be achieved through simple plugging and unplugging operations. This working process not only ensures the movement accuracy of the pressure block 2 during the assembly and adjustment of the air gun, providing a reliable guarantee for stable ballistic performance (the pressure part maintains near-absolute vertical up and down movement, allowing the pressure point of the upward-spinning rubber to contact the BB pellet in the most correct way and generate the most accurate upward-spinning force, thus achieving the most stable ballistic effect), but also greatly improves the convenience for players to quickly disassemble and adjust the ballistics. 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 substitution or modification made by a person skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and utility model concept of the present utility model should be included within the protection scope of the present utility model.
