[0012] As a preferred scheme of the optical glass fixing base convenient for installation according to the present invention, wherein: the four clamping plates are evenly distributed in a circumferential array with the center of the fixed base as a reference.

The left end of the pull rod penetrates through the left side wall of the fixed base and extends to the outside to be fixedly connected with a second pull plate.

[0014] As a preferred scheme of the optical glass fixing base convenient for installation according to the present invention, wherein: three adjacent second triangular blocks are fixedly installed on the left side wall of the rack.

The two driving blocks are respectively slidably connected to the starting ends of the two helical grooves, and the driving blocks are adapted to the helix direction of the helical grooves.

[0017] Advantages of the present invention:

[0018] (1). The structure of the optical glass fixing base that is convenient for installation provided by the present device is simple and compact in design. Each key component (such as the fixed seat, linear groove, rotating cylinder, turntable, arc groove, movable rod, moving frame, and clamping plate) works together to achieve uniform clamping and stable fixing of the optical glass. By using the rack and gear transmission, together with the auxiliary return mechanism of the first spring, it enables the operator to complete the rapid installation and disassembly of the optical glass only by pulling the first pull plate and the second pull plate, thereby greatly improving the installation efficiency and operation convenience. At the same time, it ensures that the pressure exerted by each clamping plate on the glass edge during clamping is uniform, ensuring the stability during the detection and processing process.

[0019] (2). The present device effectively solves the problem of loosening of the clamping plate caused by the premature reset of the rack due to the resilience of the first spring by optimizing the design of the positioning assembly (including components such as the positioning plate, triangular block one, triangular block two, second spring, and second pull plate). Especially through the cooperation of the rear inclined surface of the triangular block one and the front inclined surface of the triangular block two, it ensures that when the operator pulls the first pull plate, the rack can move forward smoothly, and the positioning assembly does not interfere with the operation while realizing the locking function. This design enables the optical glass to maintain a stable state for a long time after being clamped, which not only improves the clamping and fixing effect but also ensures the continuity and convenience of the installation operation.

[0020] (3) The present device introduces an adsorption component on the basis of the clamping and positioning mechanism. By arranging components such as an air cylinder, a suction cup, a piston disc, a piston rod, and a connecting disc in the rotary cylinder, and cooperating with the helical grooves with the same helix direction arranged in the through groove, the rotational motion is converted into a linear downward movement of the piston, thereby forming a vacuum adsorption force between the suction cup and the bottom of the optical glass. This adsorption function forms a linkage with the clamping mechanism, not only increasing during the initial clamping. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In order to make the above objects, features, and advantages of the present invention more obvious and understandable, the following will make a detailed description of the specific embodiments of the present invention in conjunction with the drawings of the specification.

[0030] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0031] Secondly, the so-called "one embodiment" or "embodiment" herein refers to specific features, structures or characteristics that may be included in at least one implementation manner of the present invention. The phrase "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an individual or alternative embodiment that is mutually exclusive with other embodiments.

[0032] Embodiment 1

[0033] Referring to Figures 1 to 5 , a convenient-to-install optical glass fixing base is provided for the first embodiment of the present invention. The base includes a fixing seat 100, inside which there is an installation cavity 101, providing an internal space for the installation and movement of subsequent components; four linear grooves 102 are evenly arranged on the upper surface of the fixing seat 100, and these four linear grooves 102 are arranged in a circular array, playing a guiding and positioning role to ensure that each component in the subsequent clamping mechanism 200 can move along a predetermined trajectory.

[0034] The clamping mechanism 200 is arranged in the installation cavity 101, and its main components are a rotating cylinder 201, a turntable 202, a movable rod 203, a moving frame 204 and a clamping plate 205.

[0035] Specifically, the rotating cylinder 201 is rotationally connected to the installation cavity 101 through its central position, and a turntable 202 is fixedly installed at the upper end of its outer surface. Four arc-shaped grooves 202a are opened inside the turntable 202, and these four arc-shaped grooves 202a are correspondingly located below the linear grooves 102, playing a role in converting rotational motion into directional sliding motion. Each arc-shaped groove 202a is slidably connected with a movable rod 203. The top end of the movable rod 203 passes through the linear groove 102 and extends to the upper surface of the fixing seat 100, and is fixedly connected with a moving frame 204; the moving frame 204 further drives the clamping plates 205 fixedly installed at its top end. These clamping plates 205 are used to contact the optical glass and apply a clamping force during the installation process, so as to realize the stable fixation of the glass.

[0036] In terms of the transmission mechanism, a gear 206 is fixedly installed at the lower part of the outer surface of the rotating cylinder 201, and it is meshed with a toothed plate 207 on its left side; the rear end of the toothed plate 207 is fixedly connected with a first spring 208, and one end of the first spring 208 is fixedly connected to the rear wall of the installation cavity 101, playing an elastic return role, while the front end of the toothed plate 207 passes through the front wall of the fixing seat 100 and extends to the outside, and is fixedly connected with a first pull plate 209. The staff drives the toothed plate 207 to move along the direction of the fixing seat by pulling the first pull plate 209.

[0037] A positioning component 210 (see Embodiment 2 for details) is provided on the left side of the toothed plate 207 to prevent the toothed plate 207 from returning prematurely due to the resilience of the first spring 208. In addition, a through groove 201a is provided inside the rotating cylinder 201, which provides a transmission channel for the movement of the adsorption component 211. In order to ensure the smooth sliding of the moving frame 204 in the linear groove 102, limiting plates 212 are fixedly installed directly above the four linear grooves 102, and the moving frame 204 is slidably connected to the limiting plates 212 respectively, thereby limiting its movement stroke; at the same time, the four clamping plates 205 are evenly distributed in a circular pattern with the center of the fixed seat 100 as the reference. The centers of the clamping plates 205 are symmetric with the center of the fixed seat 100, and the center distances between the clamping plates are equal, ensuring that when clamping the optical glass, each clamping plate can apply pressure evenly, so as to achieve uniform clamping and stable fixation of the optical glass.

[0038] In actual use, after the staff places the optical glass to be detected upright on the upper surface of the fixed seat 100 and presses it slightly downward, the suction cup 211b in the adsorption component 211 (although the specific structure of the suction cup is not detailed in this embodiment, its main function is to initially adsorb the optical glass to prevent large offsets) initially adsorbs the optical glass; subsequently, the staff pulls out the first pull plate 209 outward, driving the toothed plate 207 to move outward. This action causes the gear 206 to rotate, and then drives the turntable 202 to rotate through the rotating cylinder 201. The arc groove 202a in the turntable 202 causes the movable rod 203 to move along the arc direction. However, since its upper part is slidably limited in the linear groove 102, its movement is limited to a linear movement, thereby driving the moving frame 204 and the clamping plate 205 to move closer to the center of the fixed seat 100, realizing the clamping and fixation of the four sides of the optical glass; when the operator pulls a certain distance and then releases the hand, the first spring 208 at the rear end of the toothed plate 207 generates a resilience force, causing the toothed plate 207 to automatically retract to the initial position, and the clamping plate 205 also returns to its position, preparing for the next installation or disassembly.

[0039] Embodiment 2

[0040] Referring to Figures 3 to 6 , on the basis of Embodiment 1, the structural design of the positioning component 210 is further improved in this embodiment to solve the problem that after the optical glass is clamped and fixed, due to the resilience of the first spring 208, the toothed plate 207 may return prematurely, and then the clamping plate 205 cannot continuously maintain the stable clamping of the glass.

[0041] The specific improvement is as follows: The positioning component 210 includes a positioning plate 210a arranged on the left side of the tooth plate 207. The positioning plate 210a is designed to have the ability to expand and contract left and right. A row of adjacent first triangular blocks 210b are fixedly installed on its right side wall, while a second spring 210c and a pull rod 210d are fixedly installed on the left side wall of the positioning plate 210a. One end of the second spring 210c is fixedly connected to the left side wall of the fixed seat 100. The pull rod 210d passes through the left side wall of the fixed seat 100 and extends to the outside to be fixedly connected with a second pull plate 210e. At the same time, three adjacent second triangular blocks 207a are fixedly installed on the left side wall of the tooth plate 207, and these three second triangular blocks 207a are respectively located between every two first triangular blocks 210b. After clamping the optical glass, when the clamping plate 205 completes the clamping and fixing function, the positioning plate 210a and the first triangular blocks 210b on its right side will mesh with the second triangular blocks 207a on the left side of the tooth plate 207. Among them, the front right-angle surface of the first triangular block 210b abuts against the rear right-angle surface of the second triangular block 207a, and at the same time, the rear inclined surface of the first triangular block 210b abuts against the front inclined surface of the second triangular block 207a. This structural design facilitates locking the tooth plate 207, making the resilience of the first spring 208 unable to pull the tooth plate 207 back, thereby ensuring that the clamping plate 205 can continuously and stably fix the optical glass. When it is necessary to remove the optical glass, the operator only needs to pull the second pull plate 210e, and use the pull rod 210d to move the positioning plate 210a and the first triangular blocks 210b to the left until the first triangular blocks 210b are completely separated from the second triangular blocks 207a. At this time, under the action of the first spring 208, the tooth plate 207 will return to its initial position, driving the gear 206, the rotating cylinder 201 and the turntable 202 to rotate in the reverse direction, so that the movable rod 203, the moving frame 204 and the clamping plate 205 also return to their initial states synchronously, thus successfully releasing the clamping of the optical glass.

[0042] It should be noted that because the inclined surface at the rear end of the first triangular block 210b abuts against the inclined surface at the front end of the second triangular block 207a, therefore, when the staff pulls the first pull plate 209, the first triangular block 210b cannot block the forward movement of the tooth plate 207, because the second triangular block 207a can slide along the inclined surface of the first triangular block 210b, thereby squeezing the positioning plate 210a to expand and contract to the left; this design ensures that even if the positioning component 210 is set, its locking function will not prevent the staff from pulling the tooth plate 207 to complete the forward movement. Thus, even if the positioning component 210 plays a role in preventing the tooth plate 207 from resetting in advance due to the rebound of the first spring 208 after clamping the optical glass, it does not affect the staff when installing the optical glass to be detected. After placing the glass on the fixed seat 100 and pulling the first pull plate 209, the tooth plate 207 can be driven to move forward, so that the four clamping plates 205 move closer to the center of the fixed seat along the predetermined movement trajectory, realizing uniform and stable limit fixation of the glass.

[0043] Through the improvement of this positioning component, Example 2 significantly improves the stability and fixation after the optical glass is clamped, and at the same time makes the unloading operation more convenient and safe.

[0044] Example 3

[0045] Referring to Figure 2 、 Figure 3 and Figure 7 On the basis of Example 1 and Example 2, this example further introduces an adsorption component 211 to enhance the fixed stability of the optical glass during the installation process, especially to prevent the glass from shifting during the optical glass processing and detection processes.

[0046] The adsorption component 211 is mainly arranged in the through groove 201a inside the rotating cylinder 201, and its structure includes: an air cylinder 211a fixedly installed on the top wall of the installation cavity 101. The top end of the air cylinder 211a is communicated with a suction cup 211b. The suction cup 211b is arranged at the center position of the upper surface of the fixed seat 100, and is mainly used to contact the bottom of the optical glass to form a preliminary adsorption effect; a piston disk 211c is slidably connected inside the air cylinder 211a. The bottom end of the piston disk 211c is fixedly connected with a piston rod 211d. The bottom end of the piston rod 211d penetrates the inner bottom wall of the air cylinder 211a and extends into the through groove 201a, and is fixedly connected with a connecting disk 211e; driving blocks 211f are symmetrically installed at the front and rear ends of the connecting disk 211e.

[0047] In order to realize the effective movement of the piston disk 211c, two spiral grooves 201b with the same spiral direction are symmetrically arranged at the front and rear ends of the through groove 201a. The driving blocks 211f are respectively slidably connected to the starting ends of the respective spiral grooves 201b and are adapted to the spiral direction of the spiral grooves 201b; when the rotating cylinder 201 rotates, through mechanical transmission, the driving blocks 211f located in the spiral grooves 201b slide downward along the spiral grooves, thereby driving the connecting disk 211e and the piston rod 211d to move downward synchronously, causing the piston disk 211c to move downward and extract gas, and further forming a vacuum adsorption force between the suction cup 211b and the bottom of the optical glass. This adsorption force cooperates with the clamping action of the clamping mechanism 200 to further enhance the firm fixation effect of the optical glass, ensuring that the optical glass does not shift due to external forces or vibrations during the detection and subsequent processing processes.

[0048] During the operation, the staff first place the optical glass to be detected on the upper surface of the fixed base 100, slightly press it downwards to make the suction cup 211b initially adsorb the optical glass, and then pull the first pull plate 209 to drive the toothed plate 207 and the transmission mechanism to drive the turntable 202 to rotate. The movable rod 203 moves linearly along the arc groove 202a, and then the moving frame 204 and the clamping plate 205 move closer inward to clamp and fix the optical glass. At the same time, the rotation of the rotating cylinder 201 also makes the driving block 211f in the adsorption assembly 211 move downward along the spiral groove 201b, driving the piston disk 211c to move downward to pump air, forming a vacuum adsorption force, so that the adsorption between the suction cup 211b and the bottom of the optical glass is more firm. Through the combined action of this clamping and adsorption, while ensuring the stable clamping of the optical glass, Embodiment 3 also greatly improves the stability during installation and the convenience of operation.

[0049] The above three embodiments respectively elaborate on the structures of the present invention, the functions of each component and their interactions from three aspects: the construction of the basic clamping mechanism, the improvement of the positioning mechanism, and the introduction of the adsorption auxiliary mechanism, fully reflecting the technical superiority and innovation of the present invention in the field of the fixed base for optical glass that is easy to install.
