Description

Technical Field

[0001] This utility model relates to the field of prism support technology, specifically a prism support with a quick locking function. Background Technology

[0002] In the field of optics, prisms play a crucial role in various applications, including scientific research, teaching experiments, and optical inspection in industrial production. Existing prism holders use bolts and nuts to fix the prism, which is cumbersome and reduces experimental efficiency. Not only does it require a wrench to tighten the nuts, which is time-consuming and laborious, but it is also necessary to ensure that the bolts apply uniform pressure to the prism during tightening, otherwise the prism may tilt or be damaged. While clamps and springs can hold the prism together, the clamping force of these clamps is limited. After prolonged use, the elasticity weakens, leading to unstable clamping and affecting experimental results.

[0003] To address this issue, we designed a prism holder with a quick-locking function. Utility Model Content

[0004] The purpose of this invention is to provide a prism holder with a quick locking function to solve the problems mentioned in the background art.

[0005] To solve the above technical problems, this utility model provides a prism bracket with a quick locking function, including a receiving shell, a front shell and a rear shell fixedly connected to both sides of the receiving shell, a handwheel installed on the side of the rear shell away from the receiving shell, the power output end of the handwheel passing through the rear shell and fixedly connected to a drive gear, the drive gear being located inside the receiving shell;

[0006] The housing contains a driven turntable, on which a meshing toothed belt is fixedly connected. The driving gear meshes with the meshing toothed belt. The driven turntable has three arc-shaped grooves distributed in a ring. A sliding rod is slidably connected to each arc-shaped groove. A movable seat is fixedly connected to one end of the sliding rod. A clamping block is connected to the side of the movable seat away from the sliding rod. Mounting slots are provided on the front housing, the rear housing, and the driven turntable.

[0007] Furthermore, the front shell and the rear shell are provided with sliding grooves on opposite sides, the shape of which matches the arc groove, and the two ends of the sliding rod are slidably connected to the front shell and the rear shell respectively through the sliding grooves.

[0008] Furthermore, a fixing rod is fixedly connected to the side of the driven turntable near the front housing, and the fixing rod is rotatably connected to the front housing.

[0009] Furthermore, a damping bearing is connected between the power output end of the handwheel and the rear housing. The power output end of the handwheel is fixedly connected to the inner ring of the damping bearing, and the rear housing is fixedly connected to the outer ring of the damping bearing.

[0010] Furthermore, a spring is fixedly connected between the movable seat and the clamping block.

[0011] Furthermore, a base is connected to the bottom of the housing, and a support leg is fixedly connected to the bottom of the base.

[0012] Furthermore, the clamping block is made of rubber.

[0013] Furthermore, a light rod is fixedly connected to the bottom of the housing, and a sleeve is slidably connected to the outside of the light rod. A fastening bolt is threadedly connected to the sleeve, and the threaded end of the fastening bolt passes through the sleeve and abuts against the light rod. The sleeve is fixedly installed on the top of the base.

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

[0015] 1. By rotating the handwheel, the driven turntable is rotated, causing the clamping blocks to quickly move closer to each other, thus clamping and locking the prism. This effectively saves time, and the entire process does not require the use of professional tools, simplifying the installation steps, improving the efficiency of prism installation, and preventing the clamping from becoming unstable due to increased usage time.

[0016] 2. When clamping the prism, the spring can buffer the impact force of the clamping block on the prism, avoiding damage to the prism surface due to rigid contact. Move the optical rod to make it slide up and down in the sleeve, thereby adjusting the height of the housing. After adjusting to the appropriate position, tighten the fastening bolt, and use the friction between the bolt and the optical rod to fix the height of the housing. This allows for easy adjustment of the prism's height position according to actual needs, meeting different optical path height requirements and increasing the flexibility and practicality of the prism bracket.

Detailed Implementation

[0022] 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.

[0023] Please see Figures 1-4 This utility model provides a technical solution: a prism bracket with a quick locking function, including a housing 7, a front housing 1 and a rear housing 10 fixedly connected to both sides of the housing 7, a handwheel 9 installed on the side of the rear housing 10 away from the housing 7, the power output end of the handwheel 9 passes through the rear housing 10 and is fixedly connected to a drive gear 11, the drive gear 11 is located inside the housing 7.

[0024] The housing 7 has a driven turntable 12 inside, and a meshing toothed belt 13 is fixedly connected to the driven turntable 12. The driving gear 11 meshes with the meshing toothed belt 13. The driven turntable 12 has three arc-shaped grooves 14 distributed in a ring. The arc-shaped grooves 14 converge towards the center. The arc-shaped grooves 14 are slidably connected to a slide rod 16. One end of the slide rod 16 is fixedly connected to a movable seat 15. A clamping block 21 is connected to the side of the movable seat 15 away from the slide rod 16. The front housing 1, the rear housing 10 and the driven turntable 12 are all provided with mounting grooves 2.

[0025] In practice, the prism is placed in the middle of the mounting slot 2 and the handwheel 9 is turned to drive the drive gear 11 to rotate. Since the drive gear 11 meshes with the meshing toothed belt 13 on the driven turntable 12, the driven turntable 12 rotates accordingly. At this time, the slide rod 16 slides in the arc groove 14. Since the arc groove 14 converges towards the center, the slide rod 16 will move towards the center along the arc groove 14 during rotation. The moving seat 15 will move closer to each other as the slide rod 16 moves, thereby driving the three clamping blocks 21 to move closer to each other, thus achieving clamping and locking of the prism.

[0026] See Figure 3As shown, the front housing 1 and the rear housing 10 are provided with sliding grooves 18 on opposite sides. The shape of the sliding grooves 18 matches the arc-shaped groove 14. The two ends of the sliding rod 16 are slidably connected to the front housing 1 and the rear housing 10 respectively through the sliding grooves 18, which improves the stability of the sliding rod 16 as it moves along the arc-shaped groove 14. A fixing rod 17 is fixedly connected to the side of the driven turntable 12 near the front housing 1, connecting the driven turntable 12 to the front housing 1. The fixing rod 17 is rotatably connected to the front housing 1 through a bearing, reducing the shaking of the driven turntable 12 during rotation.

[0027] See Figure 2 and Figure 4 A damping bearing 19 is connected between the power output end of the handwheel 9 and the rear housing 10. The power output end of the handwheel 9 is fixedly connected to the inner ring of the damping bearing 19, and the rear housing 10 is fixedly connected to the outer ring of the damping bearing 19. After the prism is locked, the damping force of the damping bearing 19 will prevent the handwheel 9 from rotating due to slight collision, thereby maintaining the clamping state of the clamping block 21 on the prism.

[0028] See Figure 3 A spring 20 is fixedly connected between the movable base 15 and the clamping block 21. When clamping the prism, the spring 20 can buffer the impact force of the clamping block 21 on the prism, avoiding damage to the prism surface due to rigid contact. If the shape of the prism is slightly irregular, the spring 20 can adaptively adjust the pressure of the clamping block 21 on the prism to ensure the clamping force and improve the applicability of the bracket. The clamping block 21 is made of rubber, which increases the friction with the prism surface, thereby better fixing the prism and preventing it from sliding in the bracket. It can also further buffer the pressure on the prism, avoiding scratches or other damage to the prism surface.

[0029] See Figure 1 The bottom of the housing 7 is connected to a base 5, and the bottom of the base 5 is fixedly connected to three support legs 6, forming a relatively stable triangular structure. This distributes the weight of the support evenly on the ground or other supporting surface, improving the overall stability of the support. A guide rod 3 is fixedly connected to the bottom of the housing 7. A sleeve 4 is slidably connected to the outside of the guide rod 3. A fastening bolt 8 is threaded onto the sleeve 4, with the threaded end of the fastening bolt 8 penetrating the sleeve 4 and abutting against the guide rod 3. The sleeve 4 is fixedly installed on the top of the base 5. Moving the guide rod 3 allows it to slide up and down within the sleeve 4, thereby adjusting the height of the housing 7. After adjusting to the appropriate position, the fastening bolt 8 is tightened, using the friction between it and the guide rod 3 to fix the height of the housing 7. This allows for easy adjustment of the prism's height position according to actual needs, meeting different optical path height requirements and increasing the flexibility and practicality of the prism support.

[0030] Working principle:

[0031] Place the prism in the middle of the mounting slot 2 and turn the handwheel 9 to drive the drive gear 11 to rotate. Since the drive gear 11 meshes with the meshing toothed belt 13 on the driven turntable 12, the driven turntable 12 rotates accordingly. At this time, the slide rod 16 slides in the arc groove 14. Since the arc groove 14 converges towards the center, the slide rod 16 will move towards the center along the arc groove 14 during rotation. The moving seat 15 will move closer to each other as the slide rod 16 moves, thereby driving the three clamping blocks 21 to move closer to each other, thus achieving clamping and locking of the prism.

[0032] After the prism is clamped, the damping bearing 19 uses its own damping force to prevent the handwheel 9 from rotating due to slight impact, thus maintaining the clamping state of the clamping block 21 on the prism.

[0033] When the height of the prism needs to be adjusted, loosen the fastening bolt 8, pull the light rod 3 so that it slides up and down inside the sleeve 4, thereby adjusting the height of the housing 7. After adjusting it to the position that meets the actual optical path height requirements, tighten the fastening bolt 8 and use the friction between it and the light rod 3 to fix the height of the housing 7.
