Description

Technical Field

[0001] The utility model relates to the technical field of computer accessory processing, in particular to a sealing detection mechanism for computer accessories. Background Art

[0002] A search of the patent document with the publication number CN215726640U shows that the display screen is placed between a positioning block and a movable limiter, and then the screw is rotated to allow the adjustment block to drive the movable limiter to clamp the display screen. The connector of the air pressure detection air pump is used to contact the detection of the display screen. The air pressure detection air pump is used to achieve inflation. When the specified pressure is reached, the inflation is stopped and the air pressure is observed to see if there is any change. Then, the blades and the PTC heating plate are activated to achieve heating, and the change in air pressure is observed through heating.

[0003] The patent document states that when the display screen is inflated and pressurized, due to the pressure difference between the inside and outside of the display screen, and when the entire display screen is clamped, it can only support and fix the edge of the display screen, but lacks a corresponding support structure for the middle position of the display screen, which may cause the display screen to bend, and then cause the edge of the display screen to be damaged due to the bending, affecting the quality of the display screen.

A cross plate 33 is fixed to the upper end of the sliding rod 34, a rubber pad 32 is provided on the top of the cross plate 33, and a support plate 31 for supporting the display screen glass is provided on the top of the rubber pad 32. A threaded seat 35 is fixed to the lower end of the sliding rod 34.

[0034] In this embodiment: the clamping mechanism 2 includes two clamping side plates 21 symmetrically arranged on the limit plate 4, and the clamping side plates 21 are provided with a rotating frame 22 at one end passing through the limit plate 4, and two arc strips 24 are provided on the top of the rotating frame 22, and the lower end of the clamping side plate 21 is provided with an arc surface 23 that fits with the inner side of the arc strip 24. The rotating frame 22 is provided with two tensioning springs 25 away from its center position, and an annular ring 26 is fixed to the bottom of the rotating frame 22. The two arc strips 24 and the two tensioning springs 25 are rotationally symmetrical about the center of the rotating frame 22. A threaded hole that cooperates with the threaded seat 35 is provided at the center position of the rotating frame 22. Notches are provided on both sides of the limit plate 4 for the sliding of the two clamping side plates 21, and a guide hole is provided on the limit plate 4 at the position of the sliding rod 34. Four sliding strips are distributed in an annular manner on the outer side of the sliding rod 34, and the inner wall of the guide hole of the limit plate 4 is provided with a sliding groove that cooperates with the sliding strip.

[0035] In this embodiment: the detection mechanism 1 includes a sealing box 12, a sealing cover 11 is hinged at the upper end of the sealing box 12, a pressure gauge 14 and a vacuum pump 13 are fixed on the top of the sealing cover 11, the pressure gauge 14 is located in front of the vacuum pump 13, an air hole connected to the vacuum pump 13 is opened on the top of the sealing cover 11, and a one-way valve 6 for allowing air to flow out is installed at the air hole position inside the sealing cover 11, a sealing ring for sealing the top of the sealing box 12 is provided on the sealing cover 11, T-slots are opened on the front and back sides of the sealing box 12, and guide seats 211 for sliding in the T-slots are fixed at the front and back ends of the clamping side plates 21.

[0036] Working principle: open the sealing cover 11, push the two clamping side plates 21 away from each other, so that the arc surface 23 moves along the arc strip 24, then rotate the rotating frame 22 and stretch the two tensioning springs 25, and at the same time drive the threaded seat 35 through the threaded hole to move the sliding rod 34 and the cross plate 33 downward, and the rubber pad 32 will drive the support plate 31 to move downward, at this time put the display screen into the position between the two clamping side plates 21, then release the push of the two clamping side plates 21, and then tighten the tension of the spring 25 to drive the rotating frame 22 to rotate to the initial position, and at the same time, the rotating frame 2 The two curved bars 24 on 2 respectively drive the two clamping side plates 21 to approach each other through the curved surfaces 23, and then the display screen is clamped and fixed by the two clamping side plates 21. In addition, the threaded seat 35 is driven to move upward along the threaded hole by the reset rotation of the rotating frame 22. At this time, the sliding rod 34 drives the cross plate 33, rubber pad 32 and support plate 31 to move upward through the threaded seat 35. At this time, the glass of the display screen is attached to the support plate 31. As the sliding rod 34 continues to move upward, the rubber pad 32 begins to compress and supports the glass of the display screen through the support plate 31.

[0037] When testing the sealing performance of the display screen, buckle the sealing cover 11 on the top of the sealing box 12, and then use the sealing ring to seal the sealing box 12 and the sealing cover 11. Then use the vacuum pump 13 to evacuate the inside of the sealing cover 11 and the sealing box 12 through the air hole and the one-way valve 6, and then keep them in a low-pressure area for a certain period of time, and then observe whether the pressure reading of the pressure gauge 14 changes; if the pressure reading changes, it means that there is a problem with the sealing performance of the display screen; if the pressure reading does not change, it means that there is no problem with the sealing performance of the display screen;

[0038] When the display screen needs to be taken out, the air inlet valve 5 is opened to send external air into the sealing cover 11 and the sealing box 12, so that the internal and external air pressures are kept consistent, and then the sealing cover 11 is opened to take out the display screen.

[0039] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements shall fall within the scope of the present invention as claimed.
