Technical Field
[0001] This utility model relates to the field of clamping tool technology, specifically a clamping tool for glass. Background Technology
[0002] Among the many processes involved in glass processing, handling, and installation, glass clamping is a crucial step. Suitable clamping tools must not only be able to firmly hold the glass and prevent it from slipping and being damaged during operation.
[0003] There are many types of existing glass clamping tools, but they all have some problems that need to be solved. Traditional glass clamping tools use simple mechanical structures and mostly clamp glass by direct squeezing or expansion. When clamping and releasing glass, the volume of the clamp changes significantly. In a relatively confined working environment, the change in the volume of the clamp is very likely to cause interference and collision with other equipment or objects in the surrounding environment. Therefore, a new type of glass clamping tool is proposed. Utility Model Content
[0004] The purpose of this invention is to provide a clamping tool for glass to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a clamping tool for glass, including a pull rod, one end of which is fixed with a first connecting rod and the other end of which is fixed with a second connecting rod. The pull rod, the first connecting rod, and the second connecting rod form a door frame structure. A first clamping frame is fixed to one side of the bottom of the first connecting rod. The bottom of the second connecting rod is provided with a second limiting groove, and the second limiting groove is rotatably connected to a rotating shaft through a bearing. A cam is fixedly sleeved on the outside of the rotating shaft, and a second clamping frame is fixed on one side of the cam. A connecting frame is hinged to one side of the top of the pull rod, a screw is threaded to one side of the connecting frame, a fixing block is fixed to one side of the second connecting rod, a sleeve is fixed between the second connecting rod and the fixing block, and a steel wire rope is provided inside the sleeve; The second connecting rod is provided with a first protective component on one side and a second protective component on one side of the first protective component. The first and second protective components are used to prevent the glass from being scratched. A limiting component is provided on one side of the second connecting rod, which is used to limit the rotation angle of the cam.
[0006] Preferably, one end of the steel wire rope is connected to the cam and the other end is connected to the connecting frame. When the steel wire rope drives the cam to rotate clockwise around the rotating shaft, the first clamping frame and the second clamping frame are used to clamp and fix the glass.
[0007] Preferably, the second connecting rod has a rotating groove at its top, and one end of the screw is located inside the rotating groove.
[0008] Preferably, the limiting component includes a pawl, a support rod is hinged to one side of the top of the pawl, a handle is rotatably connected to one side of the support rod, and a first limiting groove is provided on the inner side of the second connecting rod.
[0009] Preferably, as described above, a ratchet is fixedly sleeved on the outer side of the rotating shaft, a tension spring is connected between the pawl and the inner wall of the first limiting groove, a sliding groove is provided on the inner wall of the first limiting groove, the handle is slidably connected to the inner side of the sliding groove, and the width of the sliding groove is greater than the width of the handle.
[0010] Preferably, the pawl is hinged to the inner wall of the first limiting groove, and the pawl is adapted to the outer side of the ratchet.
[0011] Preferably, the first protective component includes a base, a first protective layer is fixedly sleeved on the outside of the base, the first protective layer is made of silicone, and a plurality of first guide posts are fixed on one side of the base.
[0012] Preferably, the first clamping frame has a first screw hole on one side, a first bolt threaded to one side of the base is inserted into the first screw hole, and a plurality of first insertion slots are provided on one side of the first clamping frame, with the outer side of the first guide post adapted to the inner side of the first insertion slot.
[0013] Preferably, the second protective component includes a support frame, a second protective layer is fixedly sleeved on the outside of the support frame, the second protective layer is made of silicone, and a plurality of second insertion slots are provided on one side of the second clamping frame.
[0014] Preferably, as described above, a plurality of second guide posts are fixed on one side of the second protective layer, the outer side of the second guide posts is adapted to the inner side of the second insertion groove, a second screw hole is provided on one side of the second clamping frame, and a second bolt threaded to one side of the support frame is inserted into the inner side of the second screw hole.
[0015] Compared with the prior art, the present invention, by adopting the above technical solution, has the following technical effects: 1. A reliable transmission mechanism is formed through the threaded connection between the screw and the connecting frame, and the linkage between the connecting frame, the wire rope, and the cam. When the screw is rotated, the cam can be accurately driven to rotate through the wire rope, thereby realizing the movement of the second clamping frame. When the second clamping frame is opposite to the first clamping frame, it clamps and fixes the glass. When clamping and releasing the clamped object, the clamp does not change in volume, avoiding interference to the surrounding environment or other equipment that may be caused by changes in the size of the clamp. At the same time, it makes the tool more stable during operation, and the clamping effect will not be affected by changes in its own volume, ensuring the accuracy and stability of the clamping action.
[0016] 2. When the cam rotates clockwise for clamping, the pawl remains in contact with the ratchet under the action of the tension spring, but does not obstruct the clockwise rotation of the ratchet, allowing the clamping operation to proceed smoothly. During the clamping operation, the cooperation between the pawl and the ratchet prevents the cam from accidentally reversing. When it is necessary to release the limit, pull the handle. The handle drives the pawl to rotate around the hinge point through the support rod, causing the pawl to disengage from the ratchet. The operation is simple and convenient, ensuring that the glass is always in a stable clamping state and will not suddenly loosen or fall off.
[0017] Third, when clamping and fixing the glass, the first and second protective layers made of silicone material come into contact with the glass to avoid damage to the glass surface during clamping. When the first and second protective layers wear or are damaged due to long-term use, the operator can easily remove the old protective components and install the new first and second protective layers because of the installation method of guide post positioning and bolt connection. This extends the service life of the entire clamping tool, reduces the cost of use, and also improves the maintenance efficiency of the tool. Attached Figure Description

[0023] Example Please see Figure 1-9This utility model provides a technical solution: a clamping tool for glass, including a pull rod 1, a first connecting rod 2 fixed at one end of the pull rod 1, and a second connecting rod 3 fixed at the other end. The pull rod 1, the first connecting rod 2, and the second connecting rod 3 form a door frame structure. A first clamping frame is fixed to one side of the bottom of the first connecting rod 2. A second limiting groove 11 is provided at the bottom of the second connecting rod 3. The second limiting groove 11 is rotatably connected to a rotating shaft 12 through a bearing. A cam 8 is fixedly sleeved on the outside of the rotating shaft 12. A second clamping frame is fixed to one side of the cam 8. A connecting frame 14 is hinged to one side of the top of the pull rod 1, and a screw 13 is threaded to one side of the connecting frame 14. The operator only needs to rotate the screw 13 to clamp and release the glass. The operation can be flexibly adjusted according to the size of the object being clamped and the position to be clamped. A fixing block 10 is fixed to one side of the second connecting rod 3, and a sleeve 4 is fixed between the second connecting rod 3 and the fixing block 10. A steel wire rope 9 is provided inside the sleeve 4. The pull rod 1 is placed horizontally, and the first clamping frame at the bottom of the first connecting rod 2 and the second clamping frame at the bottom of the second connecting rod 3 are in an open state. The protrusion of the cam 8 is at its lowest point, and the steel wire rope 9 is in a slack state. Figure 3 This is the initial state; One end of the steel wire rope 9 is connected to the cam 8, and the other end is connected to the connecting frame 14. When the steel wire rope 9 drives the cam 8 to rotate clockwise around the rotating shaft 12, the first clamping frame and the second clamping frame are used to clamp and fix the glass. The top of the second connecting rod 3 is provided with a rotating groove 15, and one end of the screw 13 is located inside the rotating groove 15. The top of the screw 13 is provided with a limit ring (not shown in the figure). When the limit ring is released from the connecting frame 14, it is a limiting structure. When the screw 13 is manually rotated, the connecting frame 14 and the screw 13 are connected. The screw 13 is connected to and hinged to the pull rod 1. The rotation of the screw 13 will cause one end of the connecting frame 14 to tilt upwards. At the same time, one end of the screw 13 rotates in the rotation groove 15 of the second connecting rod 3. The movement of the connecting frame 14 will pull the steel wire rope 9. After being guided by the sleeve 4, the steel wire rope 9 will drive the cam 8 to rotate clockwise around the rotating shaft 12. The cam 8 will gradually lift upwards. When the cam 8 rotates, the second clamping frame fixed on its outer side will move upwards synchronously, gradually approaching the first clamping frame at the bottom of the first connecting rod 2, forming a clamping force on the glass. Figure 4 It is in a clamping state.
[0024] The second connecting rod 3 is provided with a first protective component 6 on one side and a second protective component 7 on the other side. The first protective component 6 and the second protective component 7 are used to prevent the glass from being scratched. The second connecting rod 3 is provided with a limiting component 5 on one side. The limiting component 5 is used to limit the rotation angle of the cam 8.
[0025] The limiting assembly 5 includes a pawl 56, a support rod 57 hinged to one side of the top of the pawl 56, a handle 51 rotatably connected to one side of the support rod 57, a first limiting groove 53 opened on the inner side of the second connecting rod 3, a ratchet 55 fixedly sleeved on the outer side of the rotating shaft 12, a tension spring 54 connected between the pawl 56 and the inner wall of the first limiting groove 53, and a cover plate (not shown in the figure) located on the side of the tension spring 54 connected to one side of the second connecting rod 3 by screws. Removing the cover plate allows the tension spring 54 to be accessed. For replacement, the inner wall of the first limiting groove 53 is provided with a sliding groove 52, and the handle 51 is slidably connected to the inner side of the sliding groove 52. The width of the sliding groove 52 is greater than the width of the handle 51. The pawl 56 is hinged to the inner wall of the first limiting groove 53 and is adapted to the outer side of the ratchet 55. When the cam 8 rotates, the ratchet 55 on the rotating shaft 12 rotates synchronously. Under the tension of the tension spring 54, the pawl 56 is engaged in the tooth groove of the ratchet 55, preventing the cam 8 from rotating counterclockwise and ensuring stable clamping force.
[0026] Manually move the handle 51 to slide along the slide groove 52, causing the pawl 56 to disengage from the ratchet 55. Rotate the screw 13 in the opposite direction to reset the connecting frame 14, loosen the wire rope 9, and allow the cam 8 to rotate counterclockwise under the action of gravity. The two clamping frames open, and the glass is removed.
[0027] The first protective component 6 includes a base 62 made of metal. A first protective layer 61 made of silicone is fixedly sleeved on the outside of the base 62. Several first guide posts 63 are fixed on one side of the base 62. The first protective layer 61 of the first clamping frame first contacts the glass surface and absorbs the clamping impact through elastic deformation to prevent the glass from being scratched by hard parts. A first screw hole 65 is opened on one side of the first clamping frame. A first bolt threaded to one side of the base 62 is inserted into the inner side of the first screw hole 65. Several first insertion slots 64 are opened on one side of the first clamping frame. The outer side of the first guide post 63 is adapted to the inner side of the first insertion slot 64. The first guide post 63 of the first protective component 6 is inserted into the first insertion slot 64 of the first clamping frame to play a guiding role during installation.
[0028] The second protective component 7 includes a support frame 75, with a second protective layer 72 fixedly sleeved on the outside of the support frame 75. The second protective layer 72 is made of silicone. The second protective layer 72 of the second clamping frame first contacts the glass surface and absorbs the clamping impact through elastic deformation to prevent the glass from being scratched by hard parts. Several second insertion slots 73 are opened on one side of the second clamping frame, and several second guide posts 74 are fixed on one side of the second protective layer 72. The outer side of the second guide post 74 is adapted to the inner side of the second insertion slot 73. A second screw hole 71 is opened on one side of the second clamping frame, and a second bolt threaded to one side of the support frame 75 is inserted into the inner side of the second screw hole 71. The second guide post 74 of the second protective component 7 is inserted into the second insertion slot 73 of the second clamping frame to guide the installation. If the protective layer is worn, the first and second bolts can be unscrewed, the old first protective layer 61 and second protective layer 72 can be removed, the guide posts of the new first protective layer 61 and second protective layer 72 can be aligned with the insertion slots, and the bolts can be tightened to complete the replacement.
[0029] Working principle: The glass clamping tool structure is centered on the pull rod 1, with a first connecting rod 2 and a second connecting rod 3 fixed on both sides of the pull rod 1. A first clamping frame is fixed to one side of the bottom of the first connecting rod 2, and a cam 8 is rotatably connected to the bottom of the second connecting rod 3 through a second limiting groove 11, a bearing, and a rotating shaft 12. A second clamping frame is fixed to one side of the cam 8. The first clamping frame and the second clamping frame are in an initial separated state and are not clamping the glass. The operator rotates screw 13. Since screw 13 is threadedly connected to connecting frame 14, and connecting frame 14 is hinged to one side of the top of pull rod 1, rotating screw 13 will cause connecting frame 14 to move. When connecting frame 14 moves, it will pull steel wire rope 9. The two ends of steel wire rope 9 are respectively connected to cam 8 and one side of connecting frame 14. After being stressed, steel wire rope 9 drives cam 8 to rotate clockwise around rotating shaft 12. As cam 8 rotates, second clamping frame moves accordingly, gradually approaching first clamping frame. When second clamping frame is opposite to first clamping frame, the glass placed between them can be clamped and fixed, satisfying the secondary processing of laminated glass. This tool is small in size and does not change in volume when clamping and releasing the clamped object, depending on the size of the clamped object and the position to be clamped.
[0030] The limiting component 5 is used to limit the rotation angle of the cam 8 to prevent the cam 8 from rotating excessively or accidentally reversing during the clamping process. The pawl 56 in the limiting component 5 is hinged to the inner wall of the first limiting groove 53 on the inner side of the second connecting rod 3. The ratchet 55 is fixedly sleeved on the outer side of the rotating shaft 12. The pawl 56 is adapted to the outer side of the ratchet 55. When the cam 8 rotates clockwise to perform the clamping operation, the ratchet 55 also rotates clockwise. The pawl 56 is always in contact with the ratchet 55 under the action of the tension spring 54, but it will not hinder the clockwise rotation of the ratchet 55. The tension spring 54 is connected between the pawl 56 and the inner wall of the first limiting groove 53 to provide the pawl 56 with a pulling force in the direction of the ratchet 55. When it is necessary to stop the rotation of cam 8 or prevent it from reversing, pawl 56 will engage ratchet 55, preventing ratchet 55 from rotating counterclockwise, thus limiting the rotation angle of cam 8. When it is necessary to release the limit and allow cam 8 to reverse, the operator can pull handle 51. Handle 51 is slidably connected to the inner side of the groove 52 on the inner wall of the first limiting groove 53 on the inner side of the second connecting rod 3, and the width of the groove 52 is greater than the width of handle 51. When the operator pulls handle 51, handle 51 drives support rod 57 to move, and support rod 57 drives pawl 56 to rotate around the hinge point, causing pawl 56 to disengage from ratchet 55. At this time, cam 8 can reverse. Then, the clamping and fixing of the glass is released. A limit frame is fixed on one side of the second connecting rod 3, and the outer side of handle 51 is slidably connected to the inner side of the limit frame.
[0031] In the first protective component 6, a first protective layer 61 made of silicone is fixedly sleeved on the outside of the base 62. The silicone material is soft and can reduce rigid contact with the glass to prevent scratching the glass. Several first guide posts 63 are fixed on one side of the base 62, and several first insertion slots 64 and first screw holes 65 are opened on one side of the first clamping frame. During installation, the first guide posts 63 are inserted into the inside of the first insertion slots 64 to play a positioning role. Then, the first bolts are inserted into the first screw holes 65 and threaded to one side of the base 62 to complete the fixation of the first protective component 6 and the first clamping frame. In the second protective component 7, a second protective layer 72 made of silicone is fixedly sleeved on the outside of the support frame 75, which also serves to prevent the glass from being scratched. Several second guide posts 74 are fixed on one side of the second protective layer 72, and several second insertion slots 73 and second screw holes 71 are opened on one side of the second clamping frame. During installation, the second guide posts 74 are inserted into the inside of the second insertion slots 73 for positioning, and then the second bolts are inserted into the second screw holes 71 and threaded to one side of the support frame 75 to complete the fixation of the second protective component 7 and the second clamping frame.
[0032] The second connecting rod 3 has a rotating groove 15 at its top, and one end of the screw 13 is located inside the rotating groove 15. When the screw 13 is rotated for clamping, the screw 13 rotates within the rotating groove 15. The rotating groove 15 provides space for the rotation of the screw 13 and ensures the stability of the screw 13's rotation, allowing the entire clamping operation to proceed smoothly.
[0033] In summary, a reliable transmission mechanism is formed through the threaded connection between the screw 13 and the connecting frame 14, and the linkage between the connecting frame 14, the wire rope 9, and the cam 8. When the screw 13 is rotated, the cam 8 can be accurately rotated through the wire rope 9, thereby realizing the movement of the second clamping frame. When the second clamping frame is opposite to the first clamping frame, the glass is clamped and fixed. When clamping and releasing the clamped object, the clamp does not change in volume, avoiding interference to the surrounding environment or other equipment that may be caused by changes in the size of the clamp. At the same time, it makes the tool more stable during operation and will not affect the clamping effect due to changes in its own volume, thus ensuring the accuracy and stability of the clamping action.
[0034] When the cam 8 rotates clockwise for clamping, the pawl 56 is always in contact with the ratchet 55 under the action of the tension spring 54, but it does not hinder the clockwise rotation of the ratchet 55, so that the clamping operation can be carried out smoothly. During the clamping operation, the cooperation between the pawl 56 and the ratchet 55 can prevent the cam 8 from accidentally reversing. When it is necessary to release the limit, pull the handle 51. The handle 51 drives the pawl 56 to rotate around the hinge point through the support rod 57, so that the pawl 56 disengages from the ratchet 55. The operation process is simple and convenient, ensuring that the glass is always in a stable clamping state and will not suddenly loosen or fall off.
[0035] When clamping and fixing the glass, the first protective layer 61 and the second protective layer 72 made of silicone come into contact with the glass to avoid damage to the glass surface during clamping. When the first protective layer 61 and the second protective layer 72 wear or are damaged due to long-term use, the operator can easily remove the old protective components and install the new first protective layer 61 and the second protective layer 72 because of the installation method of guide post positioning and bolt connection. This extends the service life of the entire clamping tool, reduces the cost of use, and also improves the maintenance efficiency of the tool.
