Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a chain block flange clamp with high flexibility and size adaptability. Background Art

[0002] Vacuum clamps, also known as clamping vacuum quick-release flanges, are convenient fasteners for quickly connecting vacuum pipes. They are widely used in high-tech industries such as semiconductor manufacturing, national defense research, aerospace, biopharmaceuticals, liquid crystal, photovoltaic solar energy, etc. At present, vacuum clamps are generally flange-type caliper links. When using vacuum joints and vacuum clamps in combination, they need to be purchased separately according to the flanges of KF10, KF16, KF25 and KF40 sizes, and it is impossible to achieve a flange clamp to adapt to all sizes. The existing chain vacuum clamps are mainly composed of connecting pieces, connecting blocks, locking blocks, locking matching blocks, rivets, etc. Although the excellent sealing performance can achieve a certain degree of flexible adaptation of the size, the structure is complex, and the riveting process of the connecting pieces, connecting blocks, locking blocks, locking matching blocks, rivets and other components needs to be completed by mechanical equipment to control the articulation flexibility. At the same time, the existing flange clamps are all made of aluminum, stainless steel and other materials. For glass flanges that are vulnerable to damage in emerging application scenarios such as scientific research institutes, metal clamps have poor compatibility and are very easy to damage the glass flanges, and cannot achieve stable and lossless connection.

[0025] See attached Figure 1-3 The embodiment of the present application provides a highly flexible and size-adaptive chain block flange clamp, including:

[0026] The integrated connection block 1 is provided in plurality, and the plurality of integrated connection blocks 1 are connected to form a chain structure;

[0027] A locking fitting block 2 is provided at one end of the integrated connecting block 1 and is connected to the integrated connecting block 1;

[0028] Rivets 3 are arranged on the integrated connection block 1 and the locking matching block 2 to connect a plurality of the integrated connection blocks 1 and to connect the locking matching block 2 and the integrated connection block 1;

[0029] The locking member 4 is arranged on the locking fitting block 2 and the integrated connecting block 1, and is used to fix the locking fitting block 2 and the integrated connecting block 1 so that the chain structure formed by them is fixed on the flange.

[0030] To further optimize the above technical solution, rivet sockets 11 are respectively provided at both ends of the integrated connecting block 1. The front end of the integrated connecting block 1 is a U-shaped structure 12, and the end end is a protrusion structure 13 that cooperates with the U-shaped structure 12. The rivet socket 11 is provided on the U-shaped structure 12 and the protrusion structure 13.

[0031] To further optimize the above technical solution, the end protrusion structure 13 of the integrated connection block 1 is inserted into the head end U-shaped structure 12 of another integrated connection block 1, and connected by the rivet 3, and multiple integrated connection blocks 1 are connected to form a chain structure.

[0032] It should be noted that the integrated connection block 1 is configured so that the U-shaped structure 12 on the two integrated connection blocks 1 is matched and connected with the protrusion structure 13, and then the rivet 3 is inserted into the rivet socket 11 to fix it, so that multiple integrated connection blocks 1 are connected to form a chain structure. By connecting with different integrated connection blocks through the locking piece, it can control the adaptation length between the flange clamp chain and the flange; by changing the position of the flange clamp chain locking piece connected with different integrated connection blocks, it can achieve self-adaptation for flanges of different sizes such as KF10, KF16, KF25 and KF40.

[0033] To further optimize the above technical solution, the integrated connection block 1 is an arc-shaped structure as a whole, and a U-shaped groove 14 is arranged inside it. The integrated connection block 1 is provided with a through hole 15 at the U-shaped groove 14 for the locking member 4 to pass through.

[0034] Specifically, the arc-shaped structure design of the integrated connection block 1 enables a plurality of connection blocks to form an annular structure after being connected. In conjunction with the annular shape of the flange, the side edge of the flange can be arranged in a U-shaped groove 14 of the integrated connection block 1 to achieve fixation.

[0035] To further optimize the above technical solution, one end of the locking mating block 2 is set as a U-shaped structure 21, and the other end is a convex block structure 22 that cooperates with the U-shaped structure 21. The U-shaped structure 21 and the convex block structure 22 are provided with insertion holes 23.

[0036] To further optimize the above technical solution, the second protrusion structure 22 of the locking mating block 2 is inserted into the U-shaped structure 12 of the integrated connecting block 1 and connected by rivets 3, and the second U-shaped structure 21 is connected to the locking member 4.

[0037] In order to further optimize the above technical solution, the locking fitting block 2 is an arc-shaped structure as a whole, and a second U-shaped groove 24 is arranged inside it.

[0038] It should be noted that the structure of the locking fitting block 2 is adapted to the structure of the integrated connection block 1 , so that it can be connected with the integrated connection block 1 and fix the flange through the locking piece 4 .

[0039] To further optimize the above technical solution, the locking member 4 includes a screw 41, a gasket 42 and a butterfly nut 43. One end of the screw 41 is connected to the U-shaped structure 2 of the locking fitting block 2 through a rotating shaft, and the other end passes through the through hole 15 of the integrated connecting block 1 and is connected to the butterfly nut 43 and fixed by the butterfly nut 43. The gasket 42 is arranged on the screw 41 and between the locking fitting block 2 and the butterfly nut 43.

[0040] Specifically, the screw 41 , the washer 42 , and the butterfly nut 43 included in the locking member 4 are all common products and are easy to obtain.

[0041] To further optimize the above technical solution, the integrated connecting block 1 and the locking fitting block 2 are made of one of metal materials, polymer materials or 3D printing materials.

[0042] It should be noted that the integrated connecting block 1 and the locking mating block 2 can be made of traditional metal materials to achieve flange fixation in industrial production scenarios; common polymer materials can be used to reduce hardness and achieve non-destructive fixation of flanges made of fragile materials; 3D printing materials can be used to achieve highly flexible manufacturing.

[0043] Working principle: During preparation, the flange clamp chain can be made of 10, 20, 30 or any other number of integrated connection blocks, so that its length can be adapted to most flanges of different sizes. When in use, first confirm the number of connection blocks of the flange clamp according to the flange size, and select a flange clamp made of an appropriate number of integrated connection blocks according to the flange size, so that the length of the flange clamp is sufficient to fix the flange. When fixing, place the side of the flange in the U-shaped groove 14 of the integrated connection block 1 of the flange clamp, and fix the flange clamp with the locking piece 4. Select the integrated connection block 1 that needs to be fixed by the locking piece 4 according to the flange size, pass the screw 41 through the through hole 15 of the integrated connection block 1 to connect it to the butterfly nut 43, and tighten the screw 41 between the butterfly nut 43 and the integrated connection block 1. A gasket 42 is arranged between the integrated connecting blocks 1, and the butterfly nut 43 is tightened to realize the fixation between the locking fitting block 2 and the integrated connecting block 1. The flange clamp is connected into a chain structure by multiple integrated connecting blocks, so that when it is fixed, a suitable integrated connecting block 1 can be selected for fixation according to the flange size, so that the flange clamp can adapt to flanges of various sizes, and the preparation material of the flange clamp can be selected according to the material of the flange to be fixed. When the flange clamp is suitable for glass flanges, a polymer material can be selected. The flange clamp made of polymer material has a lower hardness and will not cause damage to fragile flanges.

[0044] Therefore, the utility model adopts a highly flexible and size-adaptive chain block flange clamp of the above structure. By flexibly and conveniently selecting the integrated connecting blocks at different positions on the chain structure for fixing, the length of the flange clamp and the flange can be changed to achieve size adaptation, and the stress can be evenly dispersed through the chain structure to achieve tight buckling of the flange. At the same time, in addition to traditional metal materials, the clamp can also be made of polymer materials, which have a lower hardness and can achieve non-destructive, rapid and tight connection of flanges made of fragile materials such as glass; 3D printing materials can also be used for easy production and manufacturing. It solves the problem that the current flange clamp cannot adapt to a variety of sizes and the compatibility of metal clamps is poor.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that they can still modify or replace the technical solution of the utility model with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the utility model.
