Problems solved by technology

[0002] In the working process of the circuit board installation of AIO PC (computer all-in-one machine), the screw components commonly used to lock the circuit board on the case are as follows: figure 1 As shown, in the process of producing AIO PC (Computer All-in-One Machine), the circuit board sometimes needs to be removed, and in the existing production process, in order to improve production efficiency, it is used to tighten or loosen screws Electric screwdriver, when it is necessary to unscrew the existing screw assembly, use the electric screwdriver to complete the quick release project, because the spring is in a compressed state during the locking process, it will give the spring an upward force, and in this industry The length of the screw used in is relatively short, so far, the existing design cannot confirm whether the screw has completely separated from the circuit board when unscrewing, so far the operator cannot make a judgment, but continues to complete the work of unscrewing the screw, which leads to In order to complete the quick release of the screws, the screws, nuts and springs will separate and fall into the inside of the AIO PC (Computer All-in-One). Because these parts are very small, it is difficult to find them. Bring certain risks, such as short-circuiting the internal lines of the AIO PC (computer all-in-one machine), causing the internal components of the AIO PC (computer all-in-one machine) to burn, which is easy to cause a fire and will bring great safety hazards to people

Embodiment Construction

[0012] In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following specific embodiments are described in detail together with the accompanying drawings.

[0013] With reference to the illustration, a screw assembly includes a screw 1, the screw 1 includes a stud 11 with an external thread 12 at the lower end, and it is characterized in that: the stud 11 of the screw is sleeved with a compression spring 2 and connected with a nut 3 connected; the upper end of the nut 3 is provided with a first circular sinking groove 31 so that the compression spring 2 falls into the first circular sinking groove 31 .

[0014] The lower end of the nut 3 is provided with a second circular sink 32 coaxial with the nut 3 , and the diameter of the second circular sink 32 is larger than that of the external thread 12 .

[0015] The above-mentioned first circular sinker 31 is coaxial with the nut 3 .

[0016] In order to protect the circui...

Abstract

The invention relates to a screw assembly, which comprises a screw. The screw comprises a stud with external threads at the lower end. The screw is characterized in that after a compression spring is sleeved on the stud, the stud is connected with a nut. A first round sink groove is arranged at the upper end portion of the nut to enable the compression spring to fall in the round sink groove. In the situation of quick dismounting, the screw assembly can guarantee that all parts are not separated and always remain integrated.

Description

technical field [0001] The invention relates to a screw assembly, which is suitable for assembly and disassembly of circuit boards of AIO PC (integrated computer). Background technique [0002] In the working process of the circuit board installation of AIO PC (computer all-in-one machine), the screw components commonly used to lock the circuit board on the case are as follows: figure 1 As shown, in the process of producing AIO PC (Computer All-in-One Machine), the circuit board sometimes needs to be removed, and in the existing production process, in order to improve production efficiency, it is used to tighten or loosen screws Electric screwdriver, when it is necessary to unscrew the existing screw assembly, use the electric screwdriver to complete the quick release project, because the spring is in a compressed state during the locking process, it will give the spring an upward force, and in this industry The length of the screw used in is relatively short, so far, the e...
