[0002] Currently, a Chinese utility model with announcement number CN202150017U discloses a new watch back cover. Although the glass cover can be fixed to the inside of the watch back cover with sealant, other problems still exist during use. For example, the sealing effect at the bottom edge is poor. The bottom of the cover is connected to the watch frame. If there is a gap between the cover and the watch frame after installation, it will have a certain impact on its waterproof performance. In addition, it lacks anti-drop cushioning function. After installation, the glass cover is in a fixed and uncushioned state. When it is hit by a drop, it cannot weaken or absorb the impact force, which makes it prone to damage. To address the above problems, we propose a watch glass cover with an edge sealing structure. Utility Model Content

[0003] The utility model aims to provide a watch glass cover with an edge sealing structure, which solves the problem that the bottom edge of the existing watch back cover has a poor sealing effect and does not have an anti-fall buffer function.

[0005] The above technical solution can achieve a good sealing effect, prevent water vapor and dust from entering the dial from the bottom edge, extend the service life of the watch, and at the same time have an anti-drop buffering function, which can reduce the impact force during collision and improve the stability and safety of the watch.

[0006] The present invention is further configured as follows: a second groove is provided inside the installation frame, and a second sealing ring is bonded inside the second groove by hot melt adhesive.

[0007] By adopting the above technical solution, the sealing effect between the glass cover and the mounting frame can be improved through the provision of the second groove and the second sealing ring.

[0008] The utility model is further configured as follows: connecting blocks are symmetrically installed on the surface of the outer frame.

[0009] By adopting the above technical solution and providing the connecting block, it is convenient for personnel to rotate the outer frame with the help of tools.

[0010] The utility model is further configured as follows: a limiting sleeve is fixedly sleeved inside the outer frame.

[0011] By adopting the above technical solution, the connection piece can be limited by setting the limiting sleeve to prevent the connection piece from tilting when moving up and down.

[0012] The utility model is further configured as follows: the outer frame and the threaded fixing sleeve are both made of stainless steel.

[0013] By adopting the above technical solution, the outer frame and the threaded fixing sleeve have the characteristics of high strength, low density and excellent corrosion resistance.

[0014] The utility model is further configured as follows: the buffer spring is made of carbon spring steel.

[0015] By adopting the above technical solution, the buffer spring has the characteristics of excellent mechanical properties, good anti-elasticity and resistance to low temperatures and corrosion.

[0016] In summary, the present invention has the following beneficial effects:

[0017] 1. The utility model first fixes the first and second sealing rings to the first and second grooves respectively with hot melt adhesive. After the first and second sealing rings are installed, the glass cover is placed into the installation frame and pressed. During the pressing, the glass cover is injected with sealant to the edge and fixed to the installation frame. After the glass cover is installed, the outer frame is grasped and the threaded fixing sleeve is screwed into the threaded groove of the watch frame. This can achieve a good sealing effect, prevent moisture and dust from entering the dial through the bottom edge, and extend the service life of the watch.

[0018] 2. The utility model works by, when a watch falls and causes the mounting frame and the glass cover to be hit, the mounting frame and the glass cover will drive the fixed sleeve to move upward under the impact. When the fixed sleeve moves upward, it will not only provide movable space for the mounting frame and the glass cover, but also press the damper and cause the buffer spring to contract and store energy. The damper and the buffer spring will weaken and absorb the impact force when storing energy, and can have an anti-fall buffering function, which can reduce the impact force during collision and improve the stability and safety of the watch.
