It solves the problem that currently, when using a three-jaw connecting plate, operators need to constantly adjust various knobs and tighten various screws to control the movement of the three-jaw connecting plate, which requires complex operation, takes a long time, and affects the efficiency of photoelectric measuring instruments.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a three-jaw connecting plate for a photoelectric measuring instrument, comprising a base plate, a photoelectric measuring instrument body fixedly connected to the top of the base plate via a bracket, a base fixedly connected to the top of the base plate, an annular slide rail fixedly connected to the top of the base, and sliders slidably connected inside the annular slide rail, the number of sliders being several, the sliders being evenly distributed in a ring inside the annular slide rail, a toothed ring fixedly connected to the top of the sliders, a support tube fixedly connected to the top of the base, and three fan-shaped panels fixedly connected to the top of the support tube, the fan-shaped panels being evenly distributed in a ring on the top of the support tube, the surface of the fan-shaped panels being provided with T-shaped sliding grooves, and the inside of the T-shaped sliding grooves being... A movable block is connected to the movable block. A driving block is fixedly connected to the bottom of the movable block. A spiral disc tooth is fixedly connected to the top of the gear ring. The driving block meshes with the spiral disc tooth. A fixed rod is fixedly connected to the top of the movable block. A triangular groove is provided on the top of the fixed rod. A sleeve is rotatably connected to the bottom of the inner wall of the triangular groove. A movable column is slidably connected inside the sleeve. A tension spring is fixedly connected to the bottom of the movable column. The other end of the tension spring is fixedly connected to the bottom of the inner wall of the sleeve. A locking block is fixedly connected to the top of the movable column. The top view of the locking block is triangular. A disc frame is fixedly connected to the top of the locking block. A clamping plate is fixedly connected to the surface of the disc frame. The number of clamping plates is several. The clamping plates are evenly distributed in a ring on the surface of the disc frame.

[0006] In a preferred embodiment of this invention, a motor is fixedly connected to the top of the base plate, and a gear is fixedly connected to the output end of the motor, the gear meshing with a gear ring.

[0007] As a preferred embodiment of this invention, a pull rod is fixedly connected to the top of the disc frame, and a handheld ball is fixedly connected to the top of the pull rod.

[0008] As a preferred embodiment of this utility model, a reinforcing frame is fixedly connected to the bottom of the fan-shaped panel, and the other end of the reinforcing frame is fixedly connected to the top of the base. The number of reinforcing frames is two.

[0009] As a preferred embodiment of this utility model, the surface of the clamping plate is provided with anti-slip textures, and the number of anti-slip textures is several, and the anti-slip textures are evenly distributed on the surface of the clamping plate.

[0010] As a preferred embodiment of this utility model, threaded grooves are provided around the bottom of the base plate, and a threaded rod is threadedly connected inside the threaded groove, with a support pad fixedly connected to the bottom of the threaded rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model employs a base mounted on top of a base plate. An annular slide rail on the top of the base engages with a slider, allowing the gear ring to slide in an annular fashion. Simultaneously, a T-shaped groove on the fan-shaped panel connects to a movable block. The drive block meshes with the spiral disc teeth on the top of the gear ring, forming a linkage adjustment mechanism. When the gear ring rotates, the spiral disc teeth drive the drive block to slide within the T-shaped groove, thereby pushing the fixed rod and clamping plate on top of the movable block to move synchronously. This eliminates the need for frequent knob adjustments or screw tightening by the operator; the clamping plate's position can be adjusted solely by rotating the gear ring. Furthermore, the movement of the movable blocks can be adjusted to bring them closer or further apart. The sleeve, movable column, and tension spring structure on top of the fixed rod allow the locking block to automatically lock through elastic reset. Combined with the guiding effect of the triangular groove, this ensures the clamping plate is stably fixed after adjustment. This design transforms the complex manual operation of the traditional three-jaw connecting plate into a mechanized linkage adjustment, significantly simplifying the operation process, shortening the adjustment time, and improving the efficiency of photoelectric measuring instruments. At the same time, the uniformly distributed ring-shaped clamping plate structure can form a balanced clamping force on the connecting parts, ensuring connection stability and measurement accuracy. This device has the advantages of being easy to use and having good performance.

[0013] 2. This utility model automates the rotation of the gear ring by installing a motor on the top of the base plate and engaging it with a gear. The motor drives the gear to rotate, which in turn causes the gear ring to slide smoothly on the annular slide rail. Compared to manual adjustment of the gear ring, motor drive has the advantages of uniform speed and stable torque, enabling precise control of the gear ring's rotation angle and thus accurate adjustment of the clamping plate's position. This automated drive method avoids problems such as uneven force and insufficient adjustment accuracy that may occur with manual operation, making it particularly suitable for measurement scenarios requiring frequent angle or position adjustments. Operators only need to control the motor's start, stop, and direction to quickly open or close the clamping plate, significantly reducing manpower and operation time. Simultaneously, the motor's controllability ensures that the three-jaw connecting plate maintains stable adjustment accuracy under different working conditions, improving the automation level and ease of use of the entire photoelectric measuring instrument.

[0019] 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.

[0020] like Figures 1 to 4As shown, a three-jaw connecting plate for a photoelectric measuring instrument includes a base plate 1. A photoelectric measuring instrument body 2 is fixedly connected to the top of the base plate 1 via a bracket. A base 3 is fixedly connected to the top of the base plate 1. An annular slide rail 4 is fixedly connected to the top of the base 3. Several sliders 5 are slidably connected inside the annular slide rail 4, arranged in a ring. A toothed ring 6 is fixedly connected to the top of each slider 5. A support tube 7 is fixedly connected to the top of the base 3. Three fan-shaped panels 8 are fixedly connected to the top of the support tube 7, arranged in a ring. T-shaped grooves are provided on the surface of the fan-shaped panels 8, and movable blocks 9 are slidably connected inside the T-shaped grooves. A driving block 10 is fixedly connected to the bottom of the movable block 9. A spiral tooth 11 is fixedly connected to the top of the toothed ring 6, and the driving block 10 meshes with the spiral tooth 11. A fixing rod 12 is fixedly connected to the top of the movable block 9. The top of the device is provided with a triangular groove, and the bottom of the inner wall of the triangular groove is rotatably connected to a sleeve 13. The inside of the sleeve 13 is slidably connected to a movable column 14. The bottom of the movable column 14 is fixedly connected to a tension spring, and the other end of the tension spring is fixedly connected to the bottom of the inner wall of the sleeve 13. The top of the movable column 14 is fixedly connected to a locking block 15. The top view of the locking block 15 is triangular. The top of the locking block 15 is fixedly connected to a disc frame 16. The surface of the disc frame 16 is fixedly connected to a clamping plate 17. There are several clamping plates 17, which are evenly distributed in a ring on the surface of the disc frame 16. The top view cross-sectional area of ​​the locking block 15 is slightly smaller than the top view cross-sectional area of ​​the triangular groove, and the shape of each clamping plate 17 is different. The above-mentioned photoelectric measuring instrument body 2 is similar in principle to the photoelectric measuring instrument mentioned in the utility model patent disclosed in CN217112700U, which discloses a photoelectric measuring instrument with a three-jaw connecting disc, and achieves the same effect. This application will not elaborate further.

[0021] refer to Figure 1 A motor 22 is fixedly connected to the top of the base plate 1, and a gear 23 is fixedly connected to the output end of the motor 22. The gear 23 meshes with the gear ring 6.

[0022] As a technical optimization of this utility model, a motor 22 is installed on the top of the base plate 1 and meshes with the gear ring 6 through a gear 23, thus achieving automated power for the rotation of the gear ring 6. The motor 22 drives the gear 23 to rotate, thereby causing the gear ring 6 to slide smoothly on the annular slide rail 4. Compared with manual adjustment of the gear ring 6, the motor 22 drive has the advantages of uniform speed and stable torque, and can accurately control the rotation angle of the gear ring 6, thereby precisely adjusting the position of the clamping plate 17. This automated drive method avoids problems such as uneven force and insufficient adjustment accuracy that may be caused by manual operation, and is especially suitable for measurement scenarios that require frequent angle or position adjustments. The operator only needs to control the start, stop and direction of the motor 22 to quickly open or close the clamping plate 17, greatly reducing manpower input and operation time. At the same time, the controllability of the motor 22 ensures that the three-jaw connecting plate can maintain stable adjustment accuracy under different working conditions, improving the automation level and ease of use of the entire photoelectric measuring instrument.

[0023] refer to Figure 3 A pull rod 18 is fixedly connected to the top of the disc frame 16, and a hand-held ball 19 is fixedly connected to the top of the pull rod 18.

[0024] As a technical optimization of this utility model, the pull rod 18 and handheld ball 19 located on the top of the disc frame 16 provide a convenient manual adjustment interface for the operator. By holding the handheld ball 19 and pulling the pull rod 18, the disc frame 16 and clamping plate 17 can be directly moved up and down. Utilizing the sliding fit between the movable column 14 and the sleeve 13 and the elasticity of the tension spring, the locking block 15 and the triangular groove of the fixing rod 12 can be quickly separated or engaged. The handheld ball 19 is ergonomically designed, providing a comfortable grip and facilitating the application of stable tension, allowing the operator to precisely control the fine-tuning of the clamping plate 17. Especially in scenarios with limited space or requiring local position correction, the manual adjustment method compensates for the lack of flexibility in automated drive, forming a dual operation mode combining manual and automatic adjustment. This structure ensures efficiency during large-scale adjustments while meeting the needs of fine-tuning operations, improving the applicability of the three-jaw connecting disc and the user's operating experience.

[0025] refer to Figure 1 A reinforcing frame 20 is fixedly connected to the bottom of the fan-shaped panel 8, and the other end of the reinforcing frame 20 is fixedly connected to the top of the base 3. There are two reinforcing frames 20.

[0026] As a technical optimization of this utility model, a triangular support structure for the fan-shaped panel 8 is formed by fixing the reinforcing frame 20 at the bottom of the fan-shaped panel 8 to the base 3. The reinforcing frame 20 adopts a symmetrically distributed design, which can effectively disperse the radial and axial loads on the fan-shaped panel 8 during clamping, reduce the deformation or vibration of the panel caused by force, and thus ensure the linear sliding accuracy of the T-shaped slide. Since photoelectric measuring instruments have extremely high requirements for the stability of connecting components, the setting of the reinforcing frame 20 enhances the structural rigidity of the entire three-jaw connecting disc, avoids the loosening or deformation of components due to repeated force during long-term use, and extends the service life of the equipment. At the same time, the stable support of the fan-shaped panel 8 ensures the stability of the movable block 9 during sliding, avoids the meshing error between the drive block 10 and the spiral disc teeth 11 caused by panel shaking, and thus ensures the accuracy and reliability of the position adjustment of the clamping plate 17, providing a solid mechanical foundation for the high-precision measurement of photoelectric measuring instruments.

[0027] refer to Figure 1 The surface of the clamping plate 17 is provided with anti-slip textures, and there are several anti-slip textures, which are evenly distributed on the surface of the clamping plate 17.

[0028] As a technical optimization of this utility model, the uniform anti-slip texture on the surface of the clamping plate 17 significantly increases the friction between the clamping plate 17 and the clamped component. The anti-slip texture employs a multi-set, evenly distributed structural design, adaptable to connecting components of different materials and surface textures. Whether it's a smooth metal part or a textured plastic part, stable clamping can be achieved through the interlocking action of the anti-slip texture. During photoelectric measurement, the instrument may experience slight displacement due to environmental vibration or position adjustment. The presence of the anti-slip texture effectively prevents relative sliding between the clamping plate 17 and the component, avoiding measurement data deviations or the risk of the instrument falling due to loose clamping. Furthermore, the anti-slip texture design eliminates the need for additional locking devices, enhancing friction through physical contact, simplifying the structure while improving practicality. The uniform distribution of the anti-slip texture ensures balanced clamping force, allowing the connecting component to be stably constrained in all directions, further improving the clamping reliability and measurement stability of the three-jaw connecting plate. Rubber anti-slip pads can be installed on the surface of the clamping plate 17 as needed.

[0029] refer to Figure 1 The bottom of the base plate 1 is provided with threaded grooves around its perimeter, and the threaded grooves are connected to threaded rods, with a support pad 21 fixedly connected to the bottom of the threaded rods.

[0030] As a technical optimization of this utility model, an adjustable horizontal support structure is formed by the threaded groove, threaded rod, and support pad 21 at the bottom of the base plate 1. By rotating the threaded rod, the height of the support pad 21 can be adjusted according to the flatness of the ground and actual needs, keeping the base plate 1 horizontal and ensuring the stability of the reference plane of the photoelectric measuring instrument. This adjustable design can adapt to various complex measurement environments. Whether it is an uneven outdoor ground or a slightly inclined indoor table, the three-jaw connecting plate can be placed stably by adjusting the threaded rod, avoiding the impact of instrument tilting or vibration caused by uneven ground on measurement accuracy.

[0031] The working principle and usage process of this utility model are as follows: When in use, keep the base plate 1 horizontal to ensure that the reference plane of the photoelectric measuring instrument body 2 is stable; then start the motor 22 at the top of the base plate 1. The output end of the motor 22 drives the gear 23 to rotate. The gear 23 meshes with the gear ring 6 and drives the gear ring 6 to slide on the annular slide rail 4. The spiral disk teeth 11 at the top of the gear ring 6 rotate and mesh with the drive block 10, which drives the drive block 10 and the movable block 9 to slide in the T-shaped slide groove on the surface of the fan-shaped panel 8, thereby pushing the movable block 9 to move along the T-shaped slide groove, thereby indirectly driving each clamping plate 17 to move closer or further away from each other, and finally driving the clamping plates 17 on the surface of the disc frame 16 to close or open.

[0032] The operator places the material between the clamps 17, below the main body 2 of the photoelectric measuring instrument. The operator can select the appropriate shape of the clamp 17 according to the object to be fixed. When it is necessary to change the appropriate clamp 17, the operator can apply a pulling force by holding the ball 19 of the top pull rod 18 of the disc frame 16, so that the movable column 14 slides upward in the sleeve 13 and stretches the tension spring. After the locking block 15 separates from the triangular groove, the operator manually adjusts the position of the disc frame 16. Rotating the disc frame 16 drives the clamps 17 to rotate, thereby rotating the appropriate clamp 17 to the side closer to the material. The rotation of the disc frame 16 drives the adjusting block, the movable column 14 and the sleeve 13 to rotate. After adjustment, release the hand ball 19. The spring elastically resets, causing the locking block 15 to re-engage in the triangular groove for automatic locking. At this time, the disc frame 16 and the clamping plate 17 will not rotate, thus locking the clamping plate 17. The operator adjusts each clamping plate 17 to be closer to each other. After the clamping plate 17 is adjusted to a suitable position and stably clamps the part to be measured, the photoelectric measuring instrument body 2 can be used for measurement. After the measurement is completed, control the motor 22 to rotate in the reverse direction. The toothed ring 6 slides in the reverse direction, causing the spiral disc teeth 11 to drive the drive block 10 to move in the reverse direction. The movable block 9 returns to its position along the T-shaped slide groove. The clamping plate 17 releases the part to be measured. Finally, turn off the motor 22.
