Description

Technical Field

[0001] The utility model relates to the technical field of roof prism processing, in particular to a rotating device for double-sided coating of a roof prism. Background Art

[0002] A roof prism is a prism with two mutually perpendicular reflective surfaces. This type of prism has a special structure. Its roof surface is a reflective surface sandwiched by two reflective surfaces. The edges of the two surfaces are in the middle of the light path. The roof prism is small in size and can make the objective lens and the eyepiece in a straight line. Therefore, it is often used in very compact binoculars. One surface of the roof prism cannot fully reflect light. In order to reflect this part of the light, a reflective film must be coated on this surface. Double-sided coating not only improves the optical performance of the roof prism, but also enhances its durability and stability. The coating can protect the prism surface from pollution and damage, while improving reflection efficiency and reducing light loss.

[0003] The existing Chinese patent with announcement number CN218842312U discloses a rotating device for double-sided coating of a roof prism, including a body and a rotating mechanism. The body is provided with a plurality of grooves, and a rotating mechanism is provided at the bottom of the grooves. The rotating mechanism includes a rotating motor, a rotating shaft and a clamping structure. The output end of the rotating motor is connected to the rotating shaft, and the rotating shaft is connected to the clamping structure.

[0004] Although the above scheme effectively solves the problem of the color difference between the upper and lower films in the double-sided coating of the roof prism, the rotating device directly drives the clamping device to rotate through the motor. After the motor stops, the directly driven clamping device may continue to rotate due to external force or inertia because there is no self-locking mechanism, causing unsafe operation or damage to the roof prism. Therefore, it does not meet the existing needs. In this regard, we propose a rotating device for double-sided coating of roof prisms. Utility Model Content

[0005] The utility model aims to provide a rotating device for double-sided coating of a roof prism, so as to solve the problem that when the motor of the rotating device mentioned in the background art stops rotating, the roof prism may continue to rotate due to external force or inertia, thereby affecting the coating accuracy.

[0006] To achieve the above object, the utility model provides the following technical solution: a rotating device for double-sided coating of a roof prism, comprising a base, a fixing seat is arranged above the base, and the fixing seat is used to fix the roof prism;

[0007] It also includes a transmission cavity, which is opened inside the base, a rotating shaft is rotatably arranged on one side inside the transmission cavity, and one end of the rotating shaft extends to the outside of the transmission cavity, and one end of the rotating shaft located outside the transmission cavity is connected to a fixed seat;

[0008] It also includes a double-threaded transmission rod, which is rotatably arranged on the upper side of the interior of the fixing seat, and the two sides of the exterior of the double-threaded transmission rod are threadedly connected with T-shaped clamping blocks;

[0009] It also includes a threaded barrel, which is arranged on both sides of the base. The threaded barrel and the base are connected by connecting blocks, and the connecting blocks are welded and fixed to the threaded barrel and the base. The internal thread of the threaded barrel is connected to a single threaded rod, and both ends of the single threaded rod extend to the outside of the threaded barrel.

[0010] Preferably, a transmission worm wheel is provided on the outer wall of the rotating shaft at one end inside the transmission cavity, a transmission worm is provided in front of the transmission worm wheel, the transmission worm is rotationally connected to the transmission cavity, and worm transmission is performed between the transmission worm and the transmission worm wheel.

[0011] Preferably, a motor is provided on one side of the transmission cavity, and the output end of the motor is connected to the transmission worm through a coupling.

[0012] Preferably, a guide rod is provided below the double-threaded transmission rod, the guide rod is fixed to a fixing seat by welding, the guide rod passes through a T-shaped clamping block, and the guide rod and the T-shaped clamping block are slidably fitted.

[0013] Preferably, a rotating rod is provided at one end of the double-threaded transmission rod, one end of the rotating rod extends to the outside of the fixed seat, and the rotating rod is rotatably matched with the fixed seat, and a second knob is installed at one end of the rotating rod located outside the fixed seat.

[0014] Preferably, a first knob is provided at the upper end of the single threaded rod.

[0015] Preferably, an anti-sliding block is provided at the lower end of the single threaded rod.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] The utility model opens a transmission cavity inside the base. When the roof prism needs to be rotated, the motor is started, and the motor drives the transmission worm to rotate. Under the transmission of the worm, the rotating shaft drives the fixed seat to rotate the roof prism. Because the transmission worm has good self-locking performance, that is, when the motor stops, the transmission worm will also stop rotating synchronously, and the transmission worm wheel will stop rotating due to the self-locking effect, which can avoid the rotation of the fixed seat, ensure that the roof prism will not rotate accidentally, and improve the safety of operation.

[0018] The utility model provides threaded cylinders on both sides of the base. When double-sided coating is performed, the first knob can be turned, and the first knob will cause the single threaded rod to move downward, so that the anti-sliding block can be in contact and squeeze with the placement plane. The anti-sliding block is a rubber block, which can increase friction, thereby improving the stability of the base during coating and preventing the movement of the base from affecting the accuracy of coating.

[0019] The utility model has a double-threaded transmission rod rotatably arranged on the upper side of the interior of the fixing seat. When the operator turns the second knob, the double-threaded transmission rod can be rotated, and the rotation of the double-threaded transmission rod will drive the two T-shaped clamping blocks to move horizontally in opposite or opposite directions, so that the roof prism placed in the middle can be clamped and fixed, thereby conveniently and quickly fixing the roof prisms of different sizes, and at the same time, a silicone pad can be adhered and fixed to the inner wall of the T-shaped clamping block to avoid wear on the roof prism.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-4 The utility model provides a technical solution: a rotating device for double-sided coating of a roof prism, comprising a base 1, a fixing seat 12 is arranged above the base 1, and the fixing seat 12 is used to fix the roof prism;

[0027] It also includes a transmission cavity 7, which is opened inside the base 1, and a rotating shaft 11 is rotatably arranged on one side of the transmission cavity 7, and one end of the rotating shaft 11 extends to the outside of the transmission cavity 7, and one end of the rotating shaft 11 located outside the transmission cavity 7 is connected to a fixed seat 12;

[0028] It also includes a double-threaded transmission rod 13, which is rotatably arranged on the upper side of the interior of the fixed seat 12, and the two sides of the exterior of the double-threaded transmission rod 13 are threadedly connected with T-shaped clamping blocks 17;

[0029] It also includes a threaded barrel 2, which is arranged on both sides of the base 1. The threaded barrel 2 and the base 1 are connected by a connecting block 3, and the connecting blocks 3 are welded and fixed to the threaded barrel 2 and the base 1. The internal thread of the threaded barrel 2 is connected to a single threaded rod 4, and both ends of the single threaded rod 4 extend to the outside of the threaded barrel 2.

[0030] When in use, the base 1 is placed stably, and the single-threaded rod 4 is driven to rotate and move downward by turning the first knobs 5 on both sides, so that the anti-sliding block 6 is close to the placement plane, increasing the friction and improving the stability of the base 1. The second knob 16 is driven to drive the rotating rod 15 and the double-threaded transmission rod 13, so that the two T-shaped clamping blocks 17 move toward each other under the guidance of the guide rod 14 to clamp and fix the ridge prism. During the coating process, the motor 8 is started, and the worm transmission of the transmission worm 9 and the transmission worm wheel 10 is used to drive the fixed seat 12 to rotate the ridge prism. Due to the self-locking property of the worm transmission, the fixed seat 12 will remain stable after the motor 8 is stopped, thereby ensuring the coating accuracy.

[0031] See also Figure 2 and Figure 3 A transmission worm wheel 10 is arranged on the outer wall of one end of the rotating shaft 11 located inside the transmission cavity 7, and a transmission worm 9 is arranged in front of the transmission worm wheel 10. The transmission worm 9 is rotationally connected with the transmission cavity 7, and a worm transmission is performed between the transmission worm 9 and the transmission worm wheel 10. The smooth rotation of the rotating shaft 11 can be ensured by the worm transmission, and due to the self-locking property of the worm transmission, when the motor stops, the rotating shaft 11 can also maintain a fixed position to prevent accidental rotation, thereby improving the safety of operation and the coating accuracy;

[0032] See also Figure 2 and Figure 3 A motor 8 is arranged on one side of the transmission cavity 7, and the output end of the motor 8 is connected to the transmission worm 9 through a coupling. The motor 8 can conveniently drive the transmission worm 9 to rotate, thereby controlling the rotation of the rotating shaft 11 and the fixing seat 12, thereby realizing the automatic rotation coating of the roof prism, and improving the working efficiency and coating effect;

[0033] See also Figure 4A guide rod 14 is provided below the double-threaded transmission rod 13. The guide rod 14 is welded and fixed to the fixed seat 12. The guide rod 14 passes through the T-shaped clamping block 17, and the guide rod 14 and the T-shaped clamping block 17 are slidably matched. The guide rod 14 provides a stable sliding track for the T-shaped clamping block 17, ensuring that the T-shaped clamping block 17 maintains linear motion when moving, avoiding deviation or shaking, thereby improving the stability and accuracy of clamping;

[0034] See also Figure 4 A rotating rod 15 is provided at one end of the double-threaded transmission rod 13, and one end of the rotating rod 15 extends to the outside of the fixing seat 12, and the rotating rod 15 and the fixing seat 12 are rotatably matched, and a second knob 16 is installed at one end of the rotating rod 15 located outside the fixing seat 12. The operator can conveniently control the rotation of the rotating rod 15 and the double-threaded transmission rod 13 by rotating the second knob 16, thereby realizing the movement of the T-shaped clamping block 17 toward or away from each other, completing the rapid clamping or release of the roof prism, and improving the convenience and efficiency of the operation;

[0035] See also Figure 1 , Figure 2 and Figure 3 The upper end of the single threaded rod 4 is provided with a first knob 5, and the operator can conveniently control the up and down movement of the single threaded rod 4 by turning the first knob 5, thereby adjusting the pressure between the anti-sliding block 6 and the placement plane, thereby improving the stability of the base and avoiding affecting the accuracy of the coating due to the movement of the base;

[0036] See also Figure 1 , Figure 2 and Figure 3 The lower end of the single threaded rod 4 is provided with an anti-sliding block 6, which can fit closely to the placement plane, increase friction, prevent the base from sliding or shifting during the coating process, and ensure the stability and accuracy of the coating process.

[0037] Working principle: When in use, after placing the base 1, turn the first knobs 5 on both sides, the first knob 5 will drive the single-threaded rod 4 to rotate, so that the single-threaded rod 4 moves downward, and the single-threaded rod 4 will drive the anti-sliding block 6 to move synchronously, so that the anti-sliding block 6 can be squeezed and fit the plane on which it is placed, and the friction force is increased by the anti-sliding block 6, thereby improving the stability of the base 1 and avoiding affecting the accuracy of subsequent coating. Place the roof prism on the upper end of the fixed seat 12, turn the second knob 16, the second knob 16 will drive the rotating rod 15 to rotate, the rotating rod 15 will drive the double-threaded transmission rod 13 to rotate synchronously, and the double-threaded transmission rod 13 will drive the two T-shaped clamping blocks 17 to rotate synchronously. Since the T-shaped clamping blocks 17 are slidably matched with the guide rod 14, the T-shaped clamping blocks 17 are limited axially. When the two T-shaped clamping blocks 17 move toward each other, the rotation of the two T-shaped clamping blocks 17 will be converted into opposite or same horizontal linear movement. When the two T-shaped clamping blocks 17 move toward each other, the ridge prism can be clamped and fixed in the middle, thereby achieving rapid fixation, facilitating rapid coating, and improving the coating effect. During coating, the motor 8 can be started, and the motor 8 can rotate the transmission worm 9 through the coupling. Since the transmission worm 9 and the transmission worm wheel 10 are worm-driven, the transmission worm wheel 10 will drive the rotation shaft 11 to rotate synchronously, and the rotation shaft 11 will drive the fixing seat 12 to rotate synchronously, thereby realizing the rotation of the ridge prism. Since the worm drive has self-locking properties, the rotation of the fixing seat 12 can be avoided after stopping the motor 8, thereby ensuring that the ridge prism will not rotate accidentally, improving the safety of operation, and avoiding affecting the coating accuracy.
