[0042] Example 1

[0043] Please refer to Figure 1-8 The present embodiment proposes a circular cover assembly structure, comprising a cover 1 and a shell 2, wherein the cover 1 comprises a cover body 11 and a step 12, wherein the cover 1 is a glass circular cover and the edge of the cover body 11 is recessed downward and extends radially and horizontally outward to form the step 12, wherein the centers of the cover body 11 and the step 12 are coaxial, wherein the cover 1 and the shell 2 are bonded by an adhesive layer 3, wherein specifically, the shell 2 comprises a shell body 21 and an annular plate 22 extending from the inner ring edge of the upper surface of the shell body 21 to the inner diameter, wherein the width of the annular plate 22 is adapted to the step width 11, wherein during assembly, the adhesive layer 3 is covered on the step 12 and then the annular plate 22 of the shell 2 is aligned with the step position for clamping and pressing to complete the combination of the cover 1 and the shell 2.

[0044] Furthermore, the cover plate 1 and the housing 2 are also provided with corresponding positioning components. Specifically, the step 12 is provided with a first positioning component, and the housing 2 is provided with a second positioning component. The first positioning component and the second positioning component cooperate with each other for rapid positioning, thereby preventing the circular cover plate from deviating during installation and improving installation efficiency.

[0045] Further, such as Figure 1-2 As shown, the first positioning component of the step 12 is a recess 14 on the outer edge circumference of the step 12, and the second positioning component on the shell 2 is a protrusion 23 arranged on the inner wall of the shell body 21, and the protrusion 23 can be embedded in the recess 14 for positioning.

[0046] Further, such as Figure 1 As shown, the depression 14 of the step 12 is a chord formed by connecting two points on the outer edge of the step 12, and the angle formed by the two radii when the two ends of the chord connect with the center of the circle is 15-40 degrees. Further, the shape and size of the protrusion 23 are adapted to the depression 14.

[0047] Furthermore, the above-mentioned recesses 14 and protrusions 23 can be arranged asymmetrically in multiple numbers to prevent the error of reverse positioning caused by the symmetrical arrangement. Specifically, the number of the recesses 14 and the corresponding protrusions 23 is 2 to 5, preferably 2.

[0048] During installation, the adhesive layer 3 is covered on the step 12 and then the protrusion 23 of the shell 2 is aligned with the recess 14 to be snapped and pressed. Since the positioning structure is provided, the deviation of the cover plate 1 during assembly is prevented, so that the combination of the cover plate 1 and the shell 2 can be completed quickly and accurately.

[0049] Furthermore, the depression 14 may also be a notch that is narrow inside and wide outside, and the shape and size of the extended protrusion 23 are adapted to the notch, and they are engaged with each other for positioning.

[0050] Furthermore, the adhesive layer 3 is a sealant, which has the functions of adhesion, fastening and waterproofing, and has a thickness of 0.1-0.3 mm.

[0051] The cover plate 11 is further provided with a printing layer 13 according to actual product requirements. The printing layer 13 is a watch scale or pattern printed on the upper surface or the lower surface of the cover plate body 11 .

[0052] Example 2

[0053] like Figures 1 to 8 As shown, this embodiment proposes a circular cover plate assembly structure as a further improvement to embodiment 1, such as Figure 3-4 As shown, the first positioning component on the edge wall of the step 12 is the flange 15, and the second positioning component on the housing 2 is the corresponding position 24 of the flange 15. During installation, the flange 15 is embedded in the position 24 to determine the correct installation position.

[0054] Specifically, the flange 15 is formed by extending outward along the outer edge of the step 12. The flange 15 may be in the shape of a rectangle or an equilateral trapezoid that is narrow inside and wide outside. The latching position 24 is a concave groove arranged on the inner wall of the housing body 21.

[0055] Furthermore, the number of the flanges 15 and the corresponding latching positions 24 are both 2 to 5, preferably 2.

[0056] During installation, the adhesive layer 3 is covered on the step 12 avoiding the flange 15 and then the flange 15 of the shell 2 is aligned with the position 24 for clamping and pressing. Since the positioning structure is set, the deviation of the cover plate 1 during assembly is prevented, so that the combination of the cover plate 1 and the shell 2 can be completed quickly and accurately.

The first positioning column 25 is a columnar body extending downwardly along the lower surface of the ring plate 22, and its shape and size are adapted to the first groove 16.

[0060] Furthermore, the number of the first grooves 16 and the corresponding first positioning columns 25 are both 2 to 5, and are asymmetrically arranged, preferably 2.

[0061] During installation, the adhesive layer 3 is applied to the step 12 avoiding the first groove 16 during assembly, and then the first positioning column 25 of the housing 2 is aligned with the first groove 16 for insertion and pressing, so as to quickly complete the assembly operation.

During installation, the second positioning column 17 is inserted into the second groove 26 to determine the correct installation position.

[0064] Specifically, Figure 8 As shown, the second positioning column 17 is formed to protrude upward along the upper surface of the step 12. The second positioning column 17 may be circular or rectangular in shape. The second groove 26 is formed to be recessed inward along the lower surface of the ring plate 22, and its shape and size are adapted to the second positioning column 17.

[0065] Furthermore, the number of the second positioning posts 17 and the corresponding second grooves 26 is 2 to 5, and they are arranged asymmetrically, preferably 2.

[0066] During installation, the adhesive layer 3 is covered on the step 12 avoiding the second positioning column 17 during assembly, and then the second groove 26 of the housing 2 is aligned with the position of the second positioning column 17 for insertion and pressing to accurately position.

[0067] The use process of a circular cover plate assembly structure provided by the utility model is as follows: first, apply the sealant evenly on the step 12 avoiding the first positioning component, then align and install the second positioning component of the shell 2 with the first positioning component, press the step 12 and the ring plate 22 of the shell 2 against each other, and accurately complete the assembly of the cover plate and the shell, thereby greatly improving the assembly efficiency.
