[0002] Screws are tools that use the physics and mathematical principles of the circular rotation of the inclined surface of an object and the friction force to gradually fasten objects and parts. Screws are a general term for fasteners and a daily colloquialism. Screws are indispensable industrial necessities in daily life: such as very small screws used in cameras, glasses, clocks, electronics, etc.; general screws for televisions, electrical products, musical instruments, furniture, etc.; as for engineering, construction, and bridges, large screws and nuts are used; transportation equipment, airplanes, trams, cars, etc. use both large and small screws. Screws have important tasks in industry, and as long as there is industry on the earth, the function of screws will always be important.
[0003] In special occasions, the surface of the bolt needs to have an anti-corrosion effect, so the surface of the screw needs to be galvanized.
[0004] During the galvanizing process of existing screws, zinc oxide gas will be generated, which poses a threat to the life and health of workers. In addition, the existing screw galvanizing device usually puts the screws into the galvanizing tank through a mesh box, and a large number of screws are accumulated in the mesh box, and the galvanizing effect of the screws is poor. Therefore, it is necessary to design a screw surface galvanizing device. Utility Model Content
[0005] Based on this, it is necessary to provide a screw surface galvanizing device to address the above technical problems.

[0011] Preferably, a sealing film is installed on the inner wall of the box cover.
[0012] Compared with the prior art, this technical solution has at least one of the following beneficial effects:
[0013] Through the coordinated arrangement of the box cover and the sliding block, under the premise that the box body and the box cover are in a sealed state, the sliding block can still drive the screws in the receiving frame to move up and down, thereby avoiding the gas generated during galvanizing to harm the workers and improving the galvanizing effect;
[0014] Through the matching arrangement of the gear and the rack, the sliding block drives the receiving frame to move up and down, and the meshing transmission of the gear and the rack and the meshing between the gears drives the rotating shaft to rotate, so that the screws in the receiving frame move, thereby improving the galvanizing effect.

[0020] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.
[0021] See also Figures 1 to 4The embodiment of the present application provides a screw surface galvanizing device, including a box body 1 and a mounting surface 2, a sleeve 3 is installed on the mounting surface 2, a sleeve shaft 4 is slidably connected in the sleeve 3, a spring 5 is installed in the sleeve 3, one end of the spring 5 is connected to the sleeve shaft 4, a box cover 6 is installed at the bottom end of the sleeve shaft 4, a sliding block 7 is slidably and sealably connected to the box cover 6, two limit blocks 8 are installed on the sliding block 7, the limit blocks 8 are located on the upper and lower sides of the box cover 6, a receiving frame 9 is provided on the sliding block 7, a plurality of groups of rotating shafts 10 are rotatably connected to the bottom of the receiving frame 9, a gear 11 is installed on the rotating shaft 10, and the same group of gears 11 are meshed and connected, a plurality of racks 12 are installed on the inner wall of the box body 1, the number of racks 12 and the number of gears 11 groups are adapted, and the corresponding racks 12 are matched with the outermost gear 11 of the gear 11 group. The galvanizing solution level in the box body 1 is low. When the box cover 6 is not sealed with the box body 1, the sliding block 7 is slid upward to prevent the receiving frame 9 from contacting the liquid surface, and the liquid level does not affect the galvanizing of the screws in the receiving frame 9 after sealing.
[0022] In this embodiment, by sliding the sliding block 7 upward, the limiter 8 on the bottom of the sliding block 7 generates pressure on the box cover 6, thereby lifting the box cover 6 and causing the sleeve shaft 4 to compress the spring 5 in the sleeve 3. After the screw is placed in the receiving frame 9, the receiving frame 9 is inserted into the box body 1 by the elastic force of the spring 5, and the box cover 6 is sealed and connected to the top of the box body 1. During the process, the sliding block 7 slides downward, and is limited by the limiter 8 located above the box cover 6, so that the sliding block 7 will not separate from the box cover 6. During the downward movement of the box cover 6, the outermost gear 11 of the gears 11 installed on each group of rotating shafts 10 on the receiving frame 9 collides with the rack 12, causing the outermost gear 11 to rotate and finally mesh with the rack 12. Then, the receiving frame 9 is moved up and down by moving the sliding block 7 up and down. The rotating shaft 10 is rotated through the meshing of the outermost gear 11 with the rack 12 and the meshing between the gears 11 in the same group, so that the screws carried on the rotating shaft 10 can move, thereby improving the galvanizing effect.
[0023] In some embodiments, in order to facilitate the support of the screws at the bottom of the receiving frame 9 where the rotating shaft 10 cannot be installed due to the width of the rack 12, a plurality of fixed shafts 13 are provided. The fixed shafts 13 are installed at the bottom of the receiving frame 9, and the plurality of fixed shafts 13 are spaced apart from the plurality of groups of rotating shafts 10.
[0024] In some embodiments, in order to facilitate the automation of the sliding block 7 sliding up and down, a linear actuator 14 is installed on the mounting surface 2. The linear actuator 14 can be an electric cylinder, and the output end of the linear actuator 14 is connected to the sliding block 7.
[0025] In some embodiments, in order to maintain the stability of the up and down movement of the box cover 6 when replacing the galvanized screws, the number of sleeves 3 is set to four, and the four sleeves 3 are evenly distributed around the linear actuator 14.
[0026] In some embodiments, in order to facilitate the replacement of galvanized screws, a J-shaped hook 15 is installed at the bottom of the sliding block 7, and a U-shaped block 16 is installed on the receiving frame 9. The U-shaped block 16 is installed inverted, and the J-shaped hook 15 and the U-shaped block 16 are arranged in coordination. The inverted U-shaped block 16 on the receiving frame 9 is clamped in the J-shaped hook at the bottom of the sliding block 7, which is convenient for replacing the galvanized screws after the galvanizing is completed. And because the receiving frame 9 and the galvanized screws have a certain gravity, when the sliding block 7 slides downward, the receiving frame 9 will move downward together with the sliding block 7.
[0027] In some embodiments, in order to facilitate the sealed connection between the box cover 6 and the box body 1 , a sealing film 17 is installed on the inner wall of the box cover 6 .

However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
