DETAILED DESCRIPTION

[0021] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0022] like Figure 1 As shown, an embodiment of the utility model proposes an optical lens clamp, comprising two telescopic rods 1, two clamping members 2, two rotating sleeves 5, a support frame 4, two connecting rods 7, an abutment plate 22, a support assembly and a pushing assembly. The two telescopic rods 1 are in a horizontal state and are coaxially arranged. A gap is provided between the two telescopic rods 1. The two clamping members 2 are respectively fixedly connected to the movable sections adjacent to the two telescopic rods 1. The separated ends of the two telescopic rods 1 are fixedly connected to the support frame 4. When the movable section of the telescopic rod 1 moves, the gap between the two clamping members 2 will change. When the optical lens 3 needs to be fixed, the telescopic rod 1 is in an extended state. In this embodiment, a rubber layer is provided on the side of the clamping member 2, so that there is a buffer when the clamping member 2 and the optical lens 3 are in contact, thereby avoiding damage to the optical lens 3 when the two clamping members 2 are closed. The optical lens 3 is placed on the support assembly, and the support assembly keeps the optical lens 3 in a horizontal state. The rotating sleeve 5 is screwed together with the movable section of the telescopic rod 1. The rotating sleeve 5 is fixedly connected to the connecting rod 7. The outer side of the rotating sleeve 5 is rotatably connected to the support frame 4. When the movable section of the telescopic rod 1 reciprocates, the rotating sleeve 5 causes the connecting rod 7 to reciprocate between a horizontal position and a 90-degree upward rotation. The support assembly is fixedly positioned below and between the two clamping members 2 to support the lens. The pushing assembly is fixedly connected to the fixed frame 19 and the abutment plate 22, and is used to move the abutment plate 22 toward the support assembly.

[0023] like Figure 4As shown, preferably, the support assembly includes a motor 20 and a placement plate 21, the motor 20 is fixedly arranged at a position between the two clamping members 2, the placement plate 21 is horizontally arranged on the top of the motor 20, and the output shaft of the motor 20 is fixedly connected to the center of the bottom surface of the placement plate 21. A reducer is provided on the output shaft of the motor 20. When the placement plate 21 and the connecting portion 15 clamp the optical lens 3, the motor 20 drives the placement plate 21 to rotate, so that the optical lens 3 can rotate slowly, and the staff can polish the optical lens 3 from the side without manually rotating the optical lens 3. When the optical lens 3 is a convex lens, a recessed area of adapted size is provided on the top surface of the placement plate 21.

[0024] like Figure 1 、 3 As shown, preferably, a spiral groove 23 is provided inside the rotating sleeve 5, and a sliding member 6 adapted to the spiral groove 23 is fixedly provided on the movable section of the telescopic rod 1. The outer side of the rotating sleeve 5 is rotatably connected to the support frame 4, and the connecting rod 7 is fixedly connected to the outer wall of the rotating sleeve 5. The spiral groove 23 extends to the end of the rotating sleeve 5 close to the clamping member 2. In this embodiment, the end face of the rotating sleeve 5 of the spiral groove 23 is projected as a ninety-degree arc surface. When the sliding member 6 moves from one end of the spiral groove 23 to the other end, the rotating sleeve 5 rotates ninety degrees. The spiral groove 23 is provided with a lead-in angle on the side close to the clamping member 2. The sliding member 6 is fixedly provided on the side of the rotating sleeve 5 close to the clamping member 2, and a gap is provided between the sliding member 6 and the rotating sleeve 5. When the clamping member 2 fixes the optical lens 3, the sliding member 6 is located outside the rotating sleeve 5. When the abutment plate 22 needs to be moved directly above the optical lens 3, the movable section of the telescopic rod 1 contracts, so that the sliding member 6 fixedly connected to the movable section enters from one end of the rotating sleeve 5, thereby driving the rotating sleeve 5 and the connecting rod 7 to rotate.

[0025] like Figure 1 、 2As shown, preferably, the pushing assembly includes two first connecting rods 13, two second connecting rods 18, two springs 11, a third connecting rod 17, a guide sleeve 14, and a traction unit. The guide sleeve 14 is fixedly disposed on a side of the fixing frame 19 close to the support assembly, and one side of the abutment plate 22 is slidably connected to the guide sleeve 14. The midpoints of the two first connecting rods 13 or the two second connecting rods 18 are rotatably connected and provided with a rotating shaft 12. One end of the first connecting rod 13 or the second connecting rod 18 is slidably connected to the end surface of the fixing frame 19, and the other end of the first connecting rod 13 or the second connecting rod 18 is slidably connected to the end surface of the abutment plate 22. The third connecting rod 17 is coaxial with the two rotating shafts 12, and its two ends are fixedly connected to the two rotating shafts 12. The third connecting rod 17 ensures structural stability of the first connecting rod 13 and the second connecting rod 18 during rotation. The axis of the spring 11 is coaxial with the sliding direction of the first connecting rod 13 or the second connecting rod 18 on the fixed frame 19, and the two ends of the spring 11 are respectively fixedly connected to the ends of the first connecting rod 13 or the second connecting rod 18. The traction unit connects the ends of the first connecting rod 13 and the second connecting rod 18 located on the fixed frame 19 and the movable section of the telescopic rod 1. The traction unit is used to control the angle between the two first connecting rods 13 and the two second connecting rods 18 by moving the movable section of the telescopic rod 1. When the sliding member 6 has not entered the spiral groove 23 and the connecting rod 7 is in a horizontal state, the spring 11 is in an initial state, and the angle between the two first connecting rods 13 and the two second connecting rods 18 is pushed to the maximum angle by the spring 11, and the abutment plate 22 is contracted inside the guide sleeve 14; when the clamping member 2 at the end of the movable section of the telescopic rod 1 is away from the optical lens 3, the movable section shrinks the angle between the two first connecting rods 13 and the two second connecting rods 18 through the traction unit, and when the ends of the first connecting rod 13 and the second connecting rod 18 slide relative to the fixing frame 19 and the abutment plate 22, the abutment plate 22 is pushed to slide outside the guide sleeve 14, and when the fixing frame 19 rotates to directly above the support assembly, the abutment plate 22 moves to abut against the optical lens 3 placed on the support assembly.

[0026] like Figure 1As shown, preferably, the traction unit includes four traction ropes 8 and a plurality of guide pulleys 9. One end of each traction rope 8 is fixedly connected to the movable section of the telescopic rod 1. The traction ropes 8 then pass through the guide pulleys 9 fixedly mounted on the connecting rod 7. The other ends of the traction ropes 8 are fixedly connected to the ends of the first connecting rod 13 and the second connecting rod 18 on the fixed frame 19, which are away from the corresponding telescopic rod 1. The sliding direction of the first connecting rod 13 and the second connecting rod 18 on the fixed frame 19 is parallel to the movable section of the telescopic rod 1. When the movable section of the telescopic rod 1 is fully extended and one end is retracted so that the clamping member 2 is away from the optical lens 3, the traction ropes 8 are tightened and begin to pull the first connecting rod 13 and the second connecting rod 18 to slide. When using this clamp, the movable section is extended and moved a certain distance so that the clamping member 2 can fix or clamp the optical lens 3. At this time, the abutment plate 22 will not be moved. The guide sleeve 14 is provided with a wire hole for the traction rope 8. After the abutment plate 22 and the placement plate 21 clamp the optical lens, the staff uses the grinding device to grind the edge of the optical lens.

[0027] like Figure 1 As shown, preferably, the abutment plate 22 includes a connecting portion 15 and a rotating portion 16. The connecting portion 15 is a rectangular shell. The connecting portion 15 is adapted to and slidably connected to the guide sleeve 14. The rotating portion 16 is rotatably connected to the side of the connecting portion 15 away from the fixing frame 19. The inner end surface of the connecting portion 15 is slidably connected to the ends of the first connecting rod 13 and the second connecting rod 18. In this embodiment, the first connecting rod 13 and the second connecting rod 18 are located inside the guide sleeve 14 and do not contact the connecting portion 15.

[0028] Preferably, both ends of the first connecting rod 13 and the second connecting rod 18 are provided with sliding connection blocks 10, and the sliding connection blocks 10 are slidingly connected to the connecting portion 15 and the fixing frame 19 respectively, and the two ends of the spring 11 are fixedly connected to the sliding connection blocks 10 on both sides.

[0029] like Figure 5 As shown, a coaxial guide cylinder is preferably fixedly mounted on the end of the rotating sleeve 5 near the clamping member 2. A straight groove 24 is provided within the guide cylinder 24, communicating with the spiral groove 23. The straight groove is parallel to the axis of the rotating sleeve 5. When the movable section of the telescopic rod 1 moves and rotation of the rotating sleeve 5 is not required, the sliding member 6 slides into the straight groove. When the sliding member 6 enters the guide groove, the straight groove serves as a guide.

[0030] Preferably, a limit frame is further included, which is used to limit the rotation angle of the connecting rod 7. The limit frame is fixedly connected to the support frame 4. When the connecting rod 7 is in a horizontal state, the limit frame abuts against the side of the connecting rod 7 facing the same direction. When the connecting rod 7 is rotated upward by 90 degrees, the limit frame abuts against the other side of the connecting rod 7.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
