Description

Technical Field

[0001] This utility model relates to the field of glass processing technology, and in particular to a clamping device. Background Technology

[0002] In glass processing, experimental operations, or various scenarios requiring precise control of glass rods, the use of clamps is particularly important.

[0003] In the glass processing industry, commonly used clamping devices employ a steel ball clamping wire structure as the core clamping component. This structure applies clamping force to the glass rod through multi-point contact. However, because the contact between the steel ball and the glass rod is discrete point contact, the glass rod may experience insufficient clamping during processing, leading to loosening or displacement. Furthermore, an excessively small contact area between the glass rod and the steel ball can result in excessively high local pressure, easily causing stress concentration on the glass surface, resulting in clamping scratches or even structural damage.

[0033] One embodiment of this utility model provides a clamp for clamping a glass rod 3, see reference. Figure 1 , Figure 2 ,include:

[0034] The grip lever 1 includes a hand-held end 15 and a clamping end 16;

[0035] A clamping part 2 is installed on the clamping end 16. The clamping part 2 includes a locking member 22 and a clamping member 21. The clamping member 21 is fixed to the clamping end 16 and is used to clamp the glass rod 3.

[0036] The locking member 22 includes a reset member, a movable sleeve 225 and a pressure block. The pressure block is sleeved on the glass rod 3. The reset member is located between the movable sleeve 225 and the pressure block. The movable sleeve 225 is axially slidably sleeved on the outside of the pressure block. The movable sleeve 225 is used to drive the pressure block to move upward to clamp the glass rod 3 when force is applied.

[0037] This invention solves the problem of existing clamps being prone to loosening and damaging the glass rod 3. It employs a linkage design of a first pressure block 221, a second pressure block 222, a reset component, and a movable sleeve 225. The glass rod 3 is inserted into the insertion hole formed by the movable sleeve 225 and the pressure blocks. By pushing the movable sleeve 225, the first pressure block 221 and the second pressure block 222 are driven to move upwards, causing the first pressure block 221 and the second pressure block 222 to tighten radially inwards to clamp the glass rod 3. The clamping area is increased by the first pressure block 221 and the second pressure block 222, thus preventing damage. Specifically, the clamping part 2 is fixedly installed on the clamping end 16 of the gripping rod 1. The clamping part 2 includes a clamping member 21 and a locking member 22. The clamping member 21 and the locking member 22 are detachably connected. The locking member 22 includes a movable sleeve 225, a reset member and a pressure block. The glass rod 3 is inserted into the insertion hole formed by the movable sleeve 225 and the pressure block. When the movable sleeve 225 slides upward along the axial direction, the movable sleeve 225 drives the pressure block to move upward, and its inner side squeezes the pressure block to make the pressure block shrink radially inward, so that the pressure block clamps the glass rod 3.

[0038] Furthermore, the pressing block includes a first pressing block 221 and a second pressing block 222. The first pressing block 221 is disposed above the second pressing block 222, and the second pressing block 222 extends axially and is partially nested in the inlet end of the movable sleeve 225. Specifically, the first pressing block 221 is located above the second pressing block 222, and the lower end of the second pressing block 222 extends axially and is partially nested in the inlet end of the movable sleeve 225 and is tightly fitted to the inlet end of the movable sleeve 225. By partially nesting the second pressing block 222 in the movable sleeve 225, it can be ensured that the second pressing block 222 can slide along the axial direction of the sleeve, avoiding radial displacement or shaking of the second pressing block 222 during operation, thereby preventing damage to the glass rod 3.

[0039] Furthermore, referring to Figure 5 The first pressing block 221 has a frustum-shaped conical structure and includes multiple circumferentially distributed arc-shaped blocks, with radial deformation gaps between adjacent arc-shaped blocks. Specifically, the first pressing block 221 has a frustum-shaped conical structure and includes multiple circumferentially distributed arc-shaped blocks. The arc-shaped blocks are wider at the top and narrower at the bottom, and there are radial deformation gaps between adjacent arc-shaped blocks, allowing the first pressing block 221 to adapt to glass rods 3 of different diameters, improving the versatility of the clamp. Specifically, the movable sleeve 225 is provided with a sliding groove, and the end of the sliding groove near the clamping end 16 is an arc groove. The first pressing block 221 has a frustum-shaped conical structure that is wider at the top and narrower at the bottom. This structure allows the distance between the arc groove and the first pressing block 221 to gradually decrease as the movable sleeve 225 slides upward, that is, the arc groove gradually forms a tighter fit with the first pressing block 221, causing the first pressing block 221 to contract radially inward.

[0040] Furthermore, the second pressure block 222 includes a first end 2221 and a second end 2222. The first end 2221 and the second end 2222 are integrally formed. The radial diameter of the first end 2221 is larger than the radial diameter of the second end 2222. The first end 2221 is a conical frustum structure and includes a plurality of circumferentially evenly distributed arc-shaped blocks with radial deformation gaps between adjacent arc-shaped blocks. The second end 2222 is a cylindrical structure and is partially nested in the inlet end of the movable sleeve 225. Specifically, the first end 2221 and the second end 2222 are integrally formed structures. The radial diameter of the first end 2221 is larger than that of the second end 2222. The structure of the first end 2221 is similar to that of the first pressure block 221, both being conical frustum structures. Therefore, when the movable sleeve 225 moves upward to push the first pressure block 221 and the second pressure block 222 to slide upward, the second pressure block 222 can push the first pressure block 221 to slide upward evenly, avoiding concentrated force acting on a single point of the first pressure block 221, thus ensuring that the first pressure block 221 can be pushed smoothly. The first end 2221 includes multiple circumferentially distributed arc-shaped blocks, with radial deformation gaps between adjacent arc-shaped blocks, allowing the first end 2221 to undergo radial deformation when subjected to external force to accommodate glass rods 3 of different diameters. The second end 2222 is a cylindrical structure, partially nested in the inlet end of the movable sleeve 225, achieving a tight fit with the movable sleeve 225. This nested design ensures that the second pressure block 222 can slide along the sleeve axis without radial displacement, thus ensuring stability and accuracy during the clamping process.

[0041] Furthermore, referring to Figure 4The reset component includes a first elastic element 223 and a second elastic element 224. The first elastic element 223 is disposed between the first pressure block 221 and the clamping member 21, and the second elastic element 224 is sleeved on the second pressure block 222. The first elastic element 223 and the second elastic element 224 are used to provide a reset force after the clamping process is completed, so that the first pressure block 221 and the second pressure block 222 return to their initial state. Specifically, the first elastic element 223 is disposed between the first pressure block 221 and the clamping member 21. The clamping member 21 has a receiving cavity for accommodating the first elastic element 223 at one end near the locking member 22. The diameter of the receiving cavity is smaller than the diameter of the first pressure block 221. One end of the first elastic element 223 abuts against the first pressure block 221, and the other end abuts against the inner wall of the receiving cavity. By limiting one end of the first elastic element 223 in the receiving cavity of the clamping member 21, axial displacement of the first elastic element 223 during the contraction or stretching process can be prevented. The second elastic element 224 is sleeved on the second pressure block 222. An annular boss 226 is provided on the inner wall of the inlet end of the movable sleeve 225. One end of the second elastic element 224 abuts against the first end 2221 of the second pressure block 222, and the other end abuts against the annular boss 226. Since the radial diameter of the first end 2221 of the second pressure block 222 is larger than the radial diameter of the second end 2222, when the movable sleeve 225 slides upward, the annular boss 226 of the movable sleeve 225 presses upward against the second elastic element 224, and the second elastic element 224 pushes the second pressure block 222 upward. The movement of the movable sleeve 225 further pushes the first pressure block 221 to slide upwards. A protrusion 227 is provided inside the movable sleeve 225, which is used to press the second pressure block 222 to cause it to contract radially inwards and clamp the glass rod 3. Since the first end 2221 of the second pressure block 222 has a similar structure to the first pressure block 221, both being a conical frustum structure wider at the top and narrower at the bottom, the protrusion 227 inside the movable sleeve 225 presses the second pressure block 222 inwards during the upward sliding of the movable sleeve 225, causing the second pressure block 222 to contract radially inwards and clamp the glass rod 3. It should be noted that the first elastic element 223 and the second elastic element 224 are springs, or they can be elastic sheets or other elastic elements with elastic potential energy.

[0042] When the glass rod 3 needs to be clamped, the movable sleeve 225 moves upward under external force, and the boss presses the first elastic element 223 upward. The first elastic element 223 undergoes elastic deformation and pushes the first pressure block 221 upward, causing the second pressure block 222 to slide upward. As the movable sleeve 225 drives the first and second pressure blocks 221 and 222 to slide upward, it simultaneously drives the first and second pressure blocks 221 and 222 to gradually contract radially inward. Furthermore, the movable sleeve 225 is threadedly connected to the clamping member 21. The movable sleeve 225 rotates upward and is threadedly connected to the clamping member 21 to further compress the first elastic element 223 and the second elastic element 224, allowing the first and second pressure blocks 221 and 222 to clamp the glass rod 3 more tightly. As the movable sleeve 225 continues to rotate and rise, the clamping force of the locking member 22 on the glass rod 3 gradually increases until the required clamping force is reached. At this point, the force applied to the movable sleeve 225 can be stopped, and the device will maintain a stable clamping state. When the first pressing block 221 and the second pressing block 222 move upward under external force during clamping, the first elastic element 223 and the second elastic element 224 are compressed, storing elastic potential energy. When it is necessary to release the glass rod 3, the operator only needs to rotate the movable sleeve 225 in the opposite direction to gradually loosen the threaded connection between it and the clamping member 21. During this process, the first elastic element 223 and the second elastic element 224 release the stored elastic potential energy, pushing the first pressing block 221 and the second pressing block 222 downward, thereby releasing the clamping force on the glass rod 3.

[0043] Furthermore, the movable sleeve 225 has an internal thread at one end near the clamping member 21, and the clamping member 21 has an external thread that mates with the internal thread. A limiting boss 213 is provided on the external thread to restrict the position of the movable sleeve 225. Specifically, the movable sleeve 225 has an internal thread, and the clamping member 21 has an external thread with a limiting boss 213 to restrict the position of the movable sleeve 225, preventing excessive rotation of the movable sleeve 225 and the clamping member 21 that could damage the device.

[0044] Furthermore, referring to Figure 3 The clamping member 21 is fitted with an annular steel ball groove 211, and a plurality of steel balls 212 are disposed within the annular steel ball groove 211. Specifically, the clamping member 21 is fitted with an annular steel ball groove 211, which is located inside the gripping rod 1. When the glass rod 3 is inserted into or removed from the clamping member 21, the steel balls 212 reduce the friction between the clamping member 21 and the gripping rod 1 by rolling, allowing the glass rod 3 to move more smoothly along the gripping rod 1, thereby improving the flexibility and accuracy of operation. At the same time, the design of the steel balls 212 also enhances the stability of the clamping member 21 on the gripping rod 1, preventing unnecessary shaking or falling off during use.

[0045] Furthermore, the gripping rod 1 has a hollow structure, and a clamping space 11 is provided inside the gripping rod 1. Specifically, the gripping rod 1 is hollow, and a clamping space 11 is provided inside for accommodating the glass rod 3. The user can easily insert the glass rod 3 into the clamping space 11 of the gripping rod 1, and the glass rod 3 is firmly clamped by the corresponding clamping part 2. This design not only improves the convenience of operation, but also ensures the stability and safety of the glass rod 3 during the clamping process, effectively preventing the glass rod 3 from slipping or breaking due to unstable clamping.

[0046] Furthermore, the handheld end 15 is provided with an end cap 13, which is threadedly connected to the clamping space 11 of the gripping rod 1; an adjusting column 12 is provided in the clamping space 11 near the handheld end 15, and a sealing ring 14 is provided between the adjusting column 12 and the end cap 13. Specifically, the handheld end 15 is provided with a detachable end cap 13, and an adjusting column 12 is provided on the inner side of the end cap 13. The end cap 13, the adjusting column 12, and the gripping rod 1 are connected by threads. The effective length of the clamping space 11 can be adjusted by screwing on the end cap 13 to accommodate glass rods 3 of different lengths. A sealing ring 14 is also provided between the adjusting column 12 and the end cap 13 to prevent external moisture, dust, or other impurities from entering the clamping space 11, thereby protecting the items clamped therein from contamination or damage.
