Description

Technical Field

[0001] This utility model relates to the technical field of conical mirror fixing bases, specifically a conical mirror fixing base. Background Technology

[0002] Conical mirrors, due to their linear focal length characteristics, have been widely used in optical testing, laser resonant cavities, and large depth-of-field imaging systems. Particularly in deep ultraviolet lithography illumination systems, they are used to divide the incident beam by the apex angle of the conical mirror, improving resolution through ring illumination. However, current technologies require the purchase of multiple mounting brackets of different specifications to fix conical mirrors, increasing the cost of mounting brackets and the production cost of the conical mirrors. Furthermore, this increases the risk of damage to the mounting positions of the conical mirrors.

[0003] In the prior art, such as the stable and reliable conical mirror fixing structure disclosed in CN221079026U, the rotation of the bidirectional lead screw causes the moving blocks on both sides to move the corresponding horizontal plates inward, thereby fixing the conical mirror through the arc-shaped fixing blocks on both sides. The bidirectional lead screw can be adjusted appropriately according to the size of the conical mirror, and the fixing position of the conical mirror is protected by protective pads to avoid local damage. Therefore, it is not necessary to purchase and use multiple fixing bases of different specifications, which reduces the cost of using conical mirror fixing bases and also reduces the production cost of conical mirrors.

[0004] However, in the prior art, when the conical mirror is placed on top of the mounting base, it is easy for it to collide with the mounting base due to its own weight, which can easily cause the conical mirror to be damaged by the impact. Utility Model Content

[0005] The purpose of this utility model is to provide a conical mirror fixing base to solve the problem mentioned in the background art that when the conical mirror is placed on top of the fixing base, it is easy for the mirror to collide with the fixing base due to its own weight, which can easily cause the mirror to be damaged by impact.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a conical mirror fixing base, including a base, a buffer device installed at the top center of the base, a fixing device installed at the center of the base, and mounting devices installed at the bottom of the left and right ends of the base.

[0007] The buffer device includes an adjusting rod with a knob installed at the bottom end. A sleeve is installed on the outer surface of the adjusting rod, and a first hinge is installed on the outer surface of the sleeve. A connecting rod is connected to the end of the first hinge away from the sleeve. A second hinge is connected to the end of the connecting rod away from the first hinge. A slider is connected to the end of the second hinge away from the connecting rod, and a buffer pad is installed on the top of the slider.

[0008] As a further optimization, the top of the adjusting rod is connected to the middle of the top surface of the base via a bearing, and the outer surface of the adjusting rod is threadedly connected to the inside of the sleeve.

[0009] As a further optimization, the outer surface of the slider is slidably connected to the inner wall of the guide groove in the middle of the top surface of the base, and the top surface of the buffer pad is provided with a V-shaped positioning groove.

[0010] As a further optimization, the fixing device includes a bidirectional screw, with limit blocks installed on the outer surface of the bidirectional screw near both ends, a fixing rod installed in the middle of the top surface of the limit block, a clamping block installed on one end of the two fixing rods close to each other, and a rubber pad installed on one side of the two clamping blocks close to each other.

[0011] As a further optimization, the outer surface of the bidirectional screw is provided with opposite threads near both ends, and the outer surfaces of the limiting block and the fixing rod are slidably connected to the inner wall of the limiting groove in the middle of the base. The rubber pad is wider at the top and narrower at the bottom, and the rubber pad is arc-shaped, so that it abuts against the outer surface of the bottom of the conical mirror when fixing the conical mirror.

[0012] As a further optimization, the installation device includes a fixing block, a fixing bolt is installed in the middle of the top surface of the fixing block, a washer is installed at the top of the fixing bolt, and a disc spring is installed at the bottom of the washer.

[0013] As a further optimization, the fixing block is fixedly installed on one end of the front and one end of the back on both sides of the base, and the outer surface of the fixing bolt is connected to the middle of the disc spring and the washer.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. By setting up a buffer device, the lifting of the sleeve and the hinge of the connecting rod at both ends are used to drive the slider and the buffer pad to adjust their positions, thereby adapting to the buffering effect when placing conical mirrors of various sizes.

[0016] 2. With the setting of the fixing device and the installation device, the shape of the rubber pad, which is wider at the top and narrower at the bottom, fits better when clamping the conical mirror, making it more stable after installation. In addition, the spring preload of the disc spring makes it easy to fine-tune the level of the base when installing the base. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1:

[0025] In existing technology, when a conical mirror is placed on top of a mounting base, its own weight can easily cause it to collide with the base, leading to damage from impact. Please refer to [reference needed]. Figures 1-5 The embodiment provides a conical mirror fixing base, which can effectively avoid damage caused by bumps during the installation and placement of the conical mirror. The conical mirror fixing base includes a base 1, a buffer device installed at the top center of the base 1, a fixing device installed in the middle of the base 1, and installation devices installed at the bottom of the left and right ends of the base 1.

[0026] The buffer device includes an adjusting rod 2, a knob 3 installed at the bottom of the adjusting rod 2, a sleeve 4 installed on the outer surface of the adjusting rod 2, a hinge 5 installed on the outer surface of the sleeve 4, a connecting rod 6 connected to the end of the hinge 5 away from the sleeve 4, a second hinge 7 connected to the end of the connecting rod 6 away from the first hinge 5, a slider 8 connected to the end of the second hinge 7 away from the connecting rod 6, and a buffer pad 9 installed on the top of the slider 8.

[0027] The top of the adjusting rod 2 is connected to the middle of the top surface of the base 1 via a bearing, and the outer surface of the adjusting rod 2 is threaded to the inside of the sleeve 4. The outer surface of the slider 8 is slidably connected to the inner wall of the guide groove in the middle of the top surface of the base 1, and the top surface of the buffer pad 9 is provided with a V-shaped positioning groove.

[0028] The buffer pad 9 is made of silicone rubber (Shore A hardness 50-70), which has excellent elastic recovery (compression set ≤10%, 23℃×24h) and aging resistance. The inner wall roughness of the V-shaped positioning groove Ra≤0.8μm avoids scratching the surface of the conical mirror.

[0029] By using the buffer device, the lifting of the sleeve 4 and the hinge of the two ends of the connecting rod 6 are used to drive the slider 8 and the buffer pad 9 to adjust their positions, thereby adapting to the buffering effect when placing conical mirrors of various sizes.

[0030] When placing the conical mirror, the adjusting rod 2 is rotated by rotating the knob 3. The sleeve 4 is threadedly connected to the outer surface of the adjusting rod 2. The outer surface of the sleeve 4 is hinged to the connecting rod 6 through the first hinge 5, and the top of the connecting rod 6 is hinged to the slider 8 through the second hinge 7. Thus, the sleeve 4 is raised and lowered during the rotation of the adjusting rod 2. During the raising and lowering of the sleeve 4, the slider 8 is driven by the connecting rod 6 to slide along the guide groove opened on the top of the base 1. The positions of multiple sliders 8 and buffer pads 9 are adjusted to adapt to conical mirrors of various sizes. During the placement of the conical mirror, a V-shaped groove is opened in the middle of the top surface of the buffer pad 9 to position and buffer the bottom of the conical mirror, effectively preventing the conical mirror from being damaged by bumps during placement.

[0031] Example 2:

[0032] Based on Implementation 1, existing technologies still have the problem that when clamping and fixing a conical mirror, the clamping structure cannot effectively fit and abut against the surface of the conical mirror, and fine-tuning of the levelness is required during installation. Please refer to [link / reference needed]. Figures 1-5 This embodiment provides a conical mirror fixing base, which can effectively solve the problem of the fitting and stability of the clamping structure, as well as the problem of adjusting the overall level during installation and fixing. The fixing device of this conical mirror fixing base includes a bidirectional screw 10. Limiting blocks 11 are installed on the outer surface of the bidirectional screw 10 near both ends. A fixing rod 12 is installed in the middle of the top surface of the limiting block 11. Clamping blocks 13 are installed on the two fixing rods 12 near each other at one end. Rubber pads 14 are installed on the two clamping blocks 13 near each other on one side. Opposite threads are formed on the outer surface of the bidirectional screw 10 near both ends. The outer surfaces of the limiting blocks 11 and the fixing rods 12 are slidably connected to the inner wall of the limiting groove in the middle of the base 1.

[0033] The mounting device includes a fixing block 15, a fixing bolt 16 is installed in the middle of the top surface of the fixing block 15, a washer 18 is installed at the top of the fixing bolt 16, and a butterfly spring 17 is installed at the bottom of the washer 18. The fixing block 15 is fixedly installed on one end of the front and one end of the back on the left and right sides of the base 1, and the outer surface of the fixing bolt 16 is connected to the butterfly spring 17 and the middle of the washer 18.

[0034] Rubber pad 14 is made of nitrile rubber (NBR) with a Shore A hardness of 40-50, possessing good elasticity and conformability, and is oil-resistant and aging-resistant (applicable temperature -20℃-80℃), preventing indentation on the conical mirror during clamping. The disc spring 17 is made of 60Si2Mn spring steel (compliant with standard GB / T 1972), with an elastic limit ≥1200MPa, ensuring stable preload.

[0035] With the setting of the fixing device and the installation device, the shape of the rubber pad 14, which is wider at the top and narrower at the bottom, fits better when clamping the conical mirror, making it more stable after installation. In addition, the spring preload of the disc spring 17 makes it easy to fine-tune the level of the base 1 when installing it.

[0036] When clamping and fixing the conical mirror, the bidirectional screw 10 is rotated, and the two ends of the bidirectional screw 10 are threadedly connected to the limiting blocks 11, so that the two limiting blocks 11 move closer or further apart. In turn, the limiting blocks 11 drive the two sets of fixing rods 12, clamping blocks 13, and rubber pads 14 to move closer or further apart, thus achieving the clamping and fixing effect on the bottom outer surface of the conical mirror. During the clamping and fixing process, the rubber pads 14, which are wider at the top and narrower at the bottom, conform to the shape of the conical mirror and abut against it, thereby achieving a stable clamping effect on the conical mirror. When installing the base 1, the fixing blocks 15 and fixing bolts 16 are set up to facilitate positioning and installation. When the fixing bolts 16 are rotated to fix the fixing blocks 15 and the base 1, the top of the fixing bolts 16 compresses the disc spring 17 and the washer 18. The spring deformation preload of the disc spring 17 is used to fine-tune the installation level of the base 1, ensuring that the conical mirror is in a horizontal working state.
