[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-5 The utility model provides an embodiment: a circuit board that is easy to assemble, comprising:

[0023] A circuit board body 1 and a support plate 2, wherein the circuit board body 1 is located above the support plate 2;

[0024] The positioning assembly 3 is installed on the circuit board body 1. The positioning assembly 3 includes a positioning column 31, which is connected to the circuit board body 1. An elastic card ball 32 is arranged at the bottom of the positioning column 31. A threaded sleeve 33 is connected to the upper surface of the positioning column 31. A guide shaft 34 runs through the interior of the positioning column 31. A top plate 35 is connected to the top of the guide shaft 34. The outer wall of the top plate 35 is connected to a threaded cylinder 37 through a ball bearing 36. The threaded cylinder 37 is threadedly connected to the outside of the threaded sleeve 33. A guide cylinder 38 is connected to the bottom of the guide shaft 34. Through the plug-in cooperation of the elastic card ball 32 and the positioning slot 21, the circuit board body 1 can be conveniently assembled. The installation and positioning can be achieved by plugging. At the same time, with the arrangement of the guide cylinder 38 and other components, the guide cylinder 38 is pressed down to achieve the contraction of the elastic card ball 32, thereby releasing the carding and positioning of the elastic card ball 32 and the positioning slot 21, thereby facilitating its disassembly, improving the protection effect of the circuit board body 1, and avoiding the circuit board body 1 from being broken due to disassembly.

[0025] Furthermore, a positioning hole is formed on the circuit board body 1 , and the small diameter shaft of the positioning column 31 passes through the bottom of the positioning hole. A positioning slot 21 is formed inside the support plate 2 , and the positioning slot 21 and the positioning column 31 are coaxially distributed.

[0026] Furthermore, the upper surface of the elastic card ball 32 is conically inclined, and the upper surface of the elastic card ball 32 contacts the lower surface of the guide cylinder 38. The lower surface of the guide cylinder 38 is an arc-shaped structure. Through the contact between the inclined elastic card ball 32 and the arc-shaped structure of the guide cylinder 38, the friction force of the abutment can be reduced, thereby facilitating the squeezing and contraction of the elastic card ball 32.

[0027] Furthermore, the outer diameter of the guide cylinder 38 is equal to the inner diameter of the positioning slot 21, a through hole adapted for the guide shaft 34 is provided on the positioning column 31, and the guide shaft 34 is connected to the positioning column 31 in an up and down sliding manner. The sliding connection plays a good guiding role and ensures the stability of the guide cylinder 38 sliding up and down.

[0028] Furthermore, the outer diameter of the threaded sleeve 33 is equal to the outer diameter of the positioning column 31, and the interior of the threaded barrel 37 is provided with an internal thread adapted to the threaded sleeve 33. Through the threaded connection between the threaded sleeve 33 and the threaded barrel 37, the threaded barrel 37 can be rotated to achieve up and down adjustment, and then the top plate 35 and the guide shaft 34 are driven to be adjusted up and down through the up and down displacement of the threaded barrel 37, thereby achieving flexible control of the position of the guide barrel 38.

[0029] Furthermore, the outer wall of the threaded barrel 37 is provided with anti-slip grooves, which increase the friction with the hand and further improve the rotation stability of the threaded barrel 37. The inner wall of the threaded barrel 37 is rotationally connected to the top plate 35 via a ball bearing 36. Through the setting of the rotating structure, the guide barrel 38 is prevented from rotating due to the rotation of the threaded barrel 37, so that the guide barrel 38 can slide up and down while maintaining its axial stillness.

[0030] Furthermore, the guide cylinder 38 is sleeved on the outside of the small diameter shaft of the positioning column 31. After the elastic card ball 32 shrinks, its outer diameter is equal to the inner diameter of the guide cylinder 38. By pressing down the guide cylinder 38, the elastic card ball 32 is compressed and shrinks, thereby releasing the elastic card ball 32 from the positioning slot 21, and the circuit board body 1 and the support plate 2 can be separated.

[0031] Working principle: The circuit board bodies 1 used in this application are all products that can be directly purchased on the market. Their principles and connection methods are all existing technologies well known to those skilled in the art, so they will not be repeated here. When the utility model is in use, the support plate 2 and the positioning assembly 3 are first installed and positioned. After the support plate 2 is installed in a suitable position, when assembling the circuit board body 1, it is only necessary to insert the corresponding elastic card ball 32 into the inside of the positioning card slot 21. The elastic expansion of the elastic card ball 32 ensures the stability of the contact between the elastic card ball 32 and the positioning card slot 21. When it is necessary to disassemble the circuit board body 1, the top plate 35 is driven downward by the ball bearing 36 through the rotation of the threaded cylinder 37, and the guide cylinder 38 is further driven downward by the guide shaft 34. The elastic card ball 32 is pressed down by the guide cylinder 38 to achieve the squeezing of the elastic card ball 32, so that the positioning card slot 21 is released by the contraction of the elastic card ball 32, thereby facilitating the assembly of the circuit board body 1.

[0032] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
