[0019] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Example 1

[0021] Please see Figures 1-2This utility model provides a technical solution: a fastener for laptop computers that is easy to assemble and disassemble, comprising: a screw 2, which is composed of a screw post 4 and a screw cap 14. The combination of the screw 2 and the screw cap 14 is a classic screw combination. The screw post 4 is fixedly connected to the lower surface of the screw cap 14. The screw post 4 has different specifications in terms of thickness and length, which can be selected according to the needs of the project. The screw cap 14 is designed as a disc shape, which can still rotate after being inserted into certain components. The screw post 4 is designed as a column, which also makes it easier and more reasonable to add threads. Threads are provided on the side wall of the screw post 4. The thread is used for fixing. The top of the screw cap 14 is provided with a cover plate 1. The cover plate 1 is to prevent the screw on the outside of the laptop from being covered by dust. Dust would cover the through hole 7 and the long groove 8 on the upper surface of the screw cap 14, which would affect the rotation of the screw. The cover plate 1 and the screw cap 14 fit tightly together. The screw 2 is fitted with a threaded sleeve 3. The screw 2 and the threaded sleeve 3 are threadedly connected. The threaded sleeve 3 is the longer nut on the screw. On the laptop, this threaded sleeve 3 is integrated with the laptop. However, the length of the threaded sleeve 3 is set according to the different components and positions. Therefore, the threaded sleeve 3 is fixed on the laptop.

[0022] In actual use, after the screw is turned into the threaded cylinder 3 and tightened, the cover plate 1 is placed on the screw cap 14. At this time, a rubber strip 12 is inserted into the long groove 8 and rubs against its side wall. Two rubber pillars 11 are inserted into the two through holes 7 respectively. The cover plate 1 and the screw cap 14 are tightly fitted together.

[0023] Example 2

[0024] Please see Figures 1-4Based on Embodiment 1, a long groove 8 is formed on the upper surface of the screw cap 14, penetrating both side walls of the screw cap 14. The long groove 8 can be inserted with a flathead screwdriver. Through holes 7 are formed on both sides of the long groove 8, symmetrically arranged. The through holes 7 must be inserted with a specific screwdriver for the screw 2. Thus, there are two methods for screwdriver insertion, which can be selected according to conditions. A rubber strip 12 is fixedly connected to the lower surface of the cover plate 1, used to completely fill the long groove 8. Two rubber posts 11 are fixedly connected to the lower surface of the cover plate 1, also to fill the two through holes 7, thus preventing fine dust from entering and protecting the long groove 8 and through holes 7 from dust accumulation. The rubber posts 11 are positioned on the rubber strip 12. On both sides, the bottom of the rubber column 11 is provided with a rubber inclined surface 13. The rubber inclined surface 13 makes the rubber column 11 more accurately inserted and will not get stuck during the insertion process. The rubber inclined surface 13 is set as a ring. The ring design makes the bottom of the rubber column 11 smaller. The two rubber columns 11 are adapted to the two through holes 7, so that the rubber column can be smoothly inserted into the through hole 7. The rubber strip 12 is adapted to the long groove 8, so that the long strip can fill the long groove 8. The upper surface of the cover plate 1 is provided with a cross groove 10. The cross groove 10 is used to directly rotate the cover plate 1 to rotate the screw 2 when the long groove 8 and the through hole 7 cannot open the device. The side wall of the cover plate 1 is provided with multiple protruding rings 9. The protruding rings 9 make it easier to remove the cover plate 1.

[0025] When it is necessary to turn screw 2, you can choose to use a tool that inserts into the long slot 8 or a tool that inserts into the through hole 7. Either way, after a long period of use, it may become inconvenient to turn. At this time, you can choose another way to turn it. When neither of the two methods can turn it, you can use a Torx screwdriver and cover plate 1 to turn it. Cover plate 1 can cover the surface of the screw to prevent dust from contacting the upper surface of the screw.

[0026] Example 3

[0027] Please see Figure 2 Based on Embodiment 2, the screw post 4 is composed of multiple threaded sections 6 connected end to end. The tail of each threaded section 6 is set to be thinner, and the side wall of the bottom of each thread is provided with an annular inclined surface 5. The radius of the annular inclined surface 5 gradually decreases from top to bottom. Therefore, the thinner part of the thread post is the most vulnerable. When it is necessary to select the length, it can be cut off as needed. In this way, one screw 2 can be used in multiple positions.

[0028] In actual use, after selecting screw 2, the screw post 4 can be cut to the required length according to the length of the threaded cylinder 3. Then, after turning the screw into the threaded cylinder 3, tighten it. After tightening, cover plate 1 is placed on screw cap 14. At this time, rubber strip 12 is inserted into the long groove 8 and rubs against its side wall. Two rubber posts 11 are inserted into the two through holes 7 respectively. Cover plate 1 and screw cap 14 are tightly fitted together. When it is necessary to remove screw 2, first remove cover plate 1, and then choose a way to turn it according to your tools. If it does not work, try another way to avoid the screw being unable to be removed due to the screwdriver slipping.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
