Description

Technical Field

[0001] This utility model relates to the field of optical instrument technology, and in particular to a rapid positioning and clamping device for glass plates. Background Technology

[0002] Large-aperture optical transmission instruments are large-scale scientific experimental facilities that are technically challenging, involve multiple disciplines, and have a high degree of engineering integration. Glass slides are commonly used as the isolation medium in large-aperture optical transmission instruments, serving both to transmit light and isolate the atmospheric environment from the experimental environment. With the continuous development of optical technology, researchers have placed higher demands on the positioning and clamping devices for glass slides, requiring them to be able to be installed quickly and stably and to facilitate subsequent maintenance and replacement.

[0003] Currently, glass slides are mainly fixed by clamping. During installation, the glass slide needs to be adjusted into place before the clamping plate is installed. When replacing the glass slide, the clamping screws need to be loosened and the clamping plate removed. The maintenance time is relatively long, which increases the risk of contamination of the experimental environment and is not conducive to controlling the cleanliness of the experimental environment. Summary of the Invention

[0004] To address the shortcomings of the existing technology, this patent application aims to provide a rapid glass slide positioning and clamping device for quickly positioning and stably supporting glass slides. The device includes a glass slide, a frame, rubber pads, a mounting bracket, spring pins, springs, and a pressure cap. Rubber pads on the sides of the frame effectively prevent damage to the glass slide due to stress concentration during installation. A positioning locking block on the frame automatically locks the slide in place after it is pushed into the mounting bracket. This invention is a purely mechanical structure, without any electrical control devices, enabling one-click installation and removal of the glass slide. The operation is simple and reliable, requiring only one person to complete glass slide replacement and maintenance, greatly improving the efficiency of glass slide installation and maintenance, and effectively ensuring the cleanliness of the experimental environment for optical transmission instruments.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A quick-positioning and clamping device for a glass sheet includes a glass sheet, a mounting frame, a quick-release unit for the glass sheet, and a locking mechanism. The mounting frame is U-shaped, with an inwardly recessed mounting groove. The quick-release unit for the glass sheet includes a frame, which is U-shaped and has a glass slot. The glass sheet is inserted into the glass slot, and the frame is inserted into the mounting groove. A positioning locking block is fixedly installed at one end of the frame, and the positioning locking block has a 45-degree chamfer. The mounting frame has a locking hole facing the positioning locking block. The locking mechanism is mounted on the mounting frame and can lock the positioning locking block inserted into the locking hole.

[0007] The glass slot of the frame is fixedly fitted with a rubber pad.

[0008] The locking mechanism includes a pressure cap, a spring, and a spring pin. The pressure cap is fixedly mounted on a mounting bracket. The spring pin includes a button end, a locking end, and a spring fixing end. The locking end of the spring pin has a 60-degree chamfer. The mounting bracket has a positioning mounting hole opposite the button end of the spring pin, and the button end extends outward through the positioning mounting hole. The mounting bracket also has a spring mounting hole. The pressure cap has a clearance blind hole opposite the spring mounting hole. The spring fixing end passes through the spring mounting hole and extends into the clearance blind hole. The spring is sleeved on the outside of the spring fixing end. One end of the spring is located in the clearance blind hole, and the other end of the spring abuts against the button end. The positioning locking block is positioned opposite the locking end.

[0009] The pressure cap and the mounting bracket are fixedly connected by assembly bolts.

[0010] After the glass piece is inserted into the frame, it fits against the side of the frame opposite the opening, with a 0.2mm gap between the glass piece and the top of the frame.

[0011] In summary, this rapid glass plate positioning and clamping device incorporates a flexible rubber pad at the contact point between the glass plate and the frame to buffer and absorb vibrations, and utilizes the mechanical properties of a spring to achieve rapid locking of the frame, effectively improving the efficiency of glass plate installation and maintenance. Specific effects are as follows:

[0012] 1. Simple structure, small installation size, and convenient and quick maintenance.

[0013] 2. The glass plate has high positioning accuracy, good stability, and is easy to operate.

[0014] 3. Low production cost and short R&D cycle. Attached Figure Description

[0020] like Figure 1-4 As shown, a quick-positioning and clamping device for a glass sheet includes a glass sheet 1, a mounting frame 6, a quick-release unit for the glass sheet, and a locking mechanism. The mounting frame 6 is U-shaped, with an inwardly recessed mounting groove. The quick-release unit for the glass sheet includes a frame 2, which is U-shaped and has a glass slot. The glass sheet 1 is inserted into the glass slot, and the frame 2 is inserted into the mounting groove. A positioning locking block 201 is fixedly installed at one end of the frame 2, and the positioning locking block 201 has a 45-degree chamfer. The mounting frame 6 has a locking hole 202 facing the positioning locking block 201. The locking mechanism is mounted on the mounting frame 6 and can lock the positioning locking block 201 inserted into the locking hole.

[0021] During implementation, a rubber pad 7 is fixedly installed in the glass slot of the frame 2.

[0022] The quick-release glass plate unit includes a frame 2, which is assembled with the glass plate 1 and rubber pads 7. This unit, serving as the smallest unit for subsequent maintenance of the glass plate, possesses good rigidity and positioning capability, enabling rapid and non-destructive replacement of the glass plate. The frame 2 integrates a positioning lock 201 and three rubber pads 7, evenly spaced on the side of the frame 2. Before replacing the glass plate 1, it is necessary to install the glass plate 1 onto the frame 2 and assemble the quick-release glass plate unit. The positioning lock 201 has a 45-degree chamfer, providing guidance and lateral pushing functions during the installation of the frame 2.

[0023] In implementation, the locking mechanism includes a pressure cap 3, a spring 5, and a spring pin 4. The pressure cap 3 is fixedly mounted on the mounting bracket 6. The spring pin 4 includes a button end, a locking end, and a spring fixing end. The locking end of the spring pin 4 has a 60-degree chamfer. The mounting bracket 6 has a positioning mounting hole opposite the button end of the spring pin 4. The button end extends outward through the positioning mounting hole. The mounting bracket 6 also has a spring mounting hole. The pressure cap 3 has a clearance blind hole opposite the spring mounting hole. The spring fixing end passes through the spring mounting hole and extends into the clearance blind hole. The spring 5 is sleeved on the outside of the spring fixing end. One end of the spring 5 is located in the clearance blind hole, and the other end of the spring 5 abuts against the button end. The positioning locking block 201 is positioned opposite the locking end.

[0024] The 60-degree chamfered surface of the spring pin 5 interacts with the 45-degree chamfered surface of the locking block 201 when the glass quick-release unit is installed, forming an automatic clearance function.

[0025] After installing the quick-release glass plate unit, the quick-release glass plate unit can be directly pushed into the mounting slot on the mounting bracket 6. The positioning locking block 201 on the frame 1 cooperates with the locking end, pushing the locking end to move, thereby compressing the spring 4. The spring pin 5 will move towards the back of the mounting bracket 6. After the frame 2 is pushed to the set position, the spring 4 returns to its original position, thereby driving the spring pin 5 to lock the frame 2, preventing the frame 2 from being displaced by external influences.

[0026] When disassembling the quick-release unit of the glass plate, the button end of the spring pin 5 needs to be pressed on the front of the mounting bracket 6, so that the spring pin 5 is pressed towards the back of the mounting bracket 6. At this time, the frame locking device is unlocked, and the frame 2 can be smoothly pulled out of the mounting bracket 6 to realize the quick-release action of the glass plate.

[0027] In practice, the pressure cap 3 and the mounting bracket 6 are fixedly connected by assembly bolts.

[0028] In practice, after the glass plate 1 is inserted into the frame 2, the glass plate 1 is attached to the side of the frame 2 facing the opening, and a 0.2mm gap is left between the top of the glass plate 1 and the frame 2.

[0029] The glass slide rapid positioning and clamping device of this embodiment has a simple structure, small size, convenient maintenance, and wide application range. It can effectively improve the efficiency of glass slide installation and maintenance and ensure the cleanliness of the experimental environment for optical transmission instruments.

[0030] Finally, it should be noted that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims and their equivalents, this utility model also intends to include these modifications and variations.
