In this way, along the length direction of the strip groove 10a, the first protrusion, the second protrusion and the third protrusion are three protrusions 13 arranged adjacent to each other, and the three protrusions 13 define an assembly channel 13a. When the fastener 50 passing through the mounting hole 30a is inserted into the assembly channel 13a, the fastener 50 cooperates with the three protrusions 13 to form a triangular support structure for the fastener 50, thereby further ensuring the stability of the assembly.

[0041] See also Figures 1 to 8As shown, in one embodiment of the utility model, the assembly structure 100 includes a component 30, a fastener 50 and a housing 10, the component 30 is formed with a mounting hole 30a, the fastener 50 penetrates the mounting hole 30a and is inserted into an assembly channel 13a of the housing 10, and the component 30 is installed on the housing 10 through the cooperation of the fastener 50, the mounting hole 30a and the assembly channel 13a. In the technical solution of the utility model, a plurality of assembly channels 13a with different mounting positions are formed on the housing 10. During the assembly process of the component 30, the component 30 has two sides arranged oppositely along its length direction. One side of the component 30 is installed on the housing 10, and the component 30 is adjusted so that the mounting hole 30a on the other side of the component 30 is opposite to the strip groove 10a. In this way, the fastener 50 penetrates the mounting hole 30a and is inserted into the assembly channel 13a arranged opposite to the mounting hole 30a, so that the component 30 is quickly assembled and the assembly efficiency of the component 30 is improved. It can be understood that a plurality of assembly channels 13a are arranged along the length direction of the component 30, so that the mounting holes 30a of the components 30 of different lengths are opposite to different assembly channels 13a, and the fasteners 50 penetrating the mounting holes 30a can be inserted into the corresponding assembly channels 13a according to the length of the component 30, so as to be compatible with the assembly of components 30 of different lengths. In this way, there is no need to drill and tap screw holes at the corresponding installation positions in order to be compatible with different components 30, and the assembly requirements of several different components 30 are met.

[0042] It should be noted that the mounting hole 30a can be a circular hole, a U-shaped hole, or a hole of other shapes, as long as the limited installation of the component 30 can be achieved. Of course, the mounting hole 30a can also be formed by setting an external structure. Specifically, the outer wall of the component 30 is convexly provided with a mounting block 31, and the mounting block 31 is connected to the adjacent surface of the component 30 to form a mounting hole 30a that penetrates the mounting block 31, and the mounting hole 30a is connected to the surface of the mounting block 31 away from the component 30.

The fastener 50 can be a threaded structural member, and the inner wall of the mounting hole 30a is provided with a thread that is threadedly connected with the threaded structural member. In this way, the fastener 50 inserted in the assembly channel 13a is locked by threaded connection to achieve stable assembly. The fastener 50 may also be a latch, through which the mounting hole 30a and the assembly channel 13a are sequentially penetrated, so that the component 30 is installed in the housing 10. Specifically, the fastener 50 is a self-tapping screw, which is penetrated in the mounting hole 30a and threadedly connected to the protrusion 13 defining the assembly channel 13a, and the size and shape of the protrusion 13 are set so that the self-tapping screw penetrating the mounting hole 30a can be stably installed in the assembly channel 13a. Of course, the fastener 50 may also be a cylindrical rod with a gradually changing diameter, and the cylindrical rod is inserted in the assembly channel 13a through an interference fit with the assembly channel 13a.

It should be noted that the self-tapping screw is a screw with a drill bit, and the front end size of the drill bit is small, which is conducive to being clamped in the assembly channel 13a formed by the protrusion 13, so as to achieve the rapid alignment of the self-tapping screw. The self-tapping screw firmly fixes the screw in the material of the protrusion 13 forming the assembly channel 13a through the self-tapping effect of the thread, preventing the component 30 from sliding relative to the housing 10, so that there is no need to set a thread that matches the screw, and the component 30 is quickly assembled on the housing 10. In addition, the nut of the self-tapping screw is pressed on the surface where the mounting hole 30a is located, and the screw of the self-tapping screw penetrates the mounting hole 30a and is threadedly connected to the protrusion 13 defining the assembly channel 13a, so as to enhance the stability of the assembly of the component 30 on the housing 10.

It should be noted that the distance between two adjacent protrusions 13 on the same side wall 11 is defined by the thread diameter of the self-tapping screw, so that while the self-tapping screw is inserted, the two adjacent protrusions 13 are guaranteed to stably limit the self-tapping screw, thereby improving the assembly stability of the component 30 on the housing 10. Specifically, the distance between two adjacent protrusions 13 of the assembly channel 13a is defined as d / 2, so that the three protrusions 13 form a stable acute-angle isosceles triangle structure, which achieves the stability of the three protrusions 13 limiting the fastener 50, and improves the assembly stability of the component 30 on the housing 10.

Specifically, W2 is equal to 0.85 to 0.95 times the thread diameter d of the self-tapping screw. It should be noted that the spacing between the protrusions 13 located on the two side walls 11 along the width direction of the strip groove 10a is limited by the thread diameter of the self-tapping screw, so that while realizing the insertion of the self-tapping screw, the protrusions 13 between the opposite side walls 11 are guaranteed to stably limit the self-tapping screw, thereby improving the assembly stability of the component 30 on the housing 10.

[0046] See also Figures 5 and 6 As shown, in one embodiment of the present invention, the thread diameter of the self-tapping screw is defined as d, and the width W1 of the strip groove 10a is less than d. It should be noted that the width of the strip groove 10a is limited by the thread diameter of the self-tapping screw, so that while the self-tapping screw is inserted, the protrusion 13 of the strip groove 10a increases the limiting effect of the self-tapping screw, thereby improving the assembly stability of the component 30 on the housing 10.
