[0028] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not require further definition and explanation in the subsequent drawings.

[0030] In the above description of the utility model, it should be noted that the terms "one side", "the other side", etc. indicate the orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, or the orientation or position relationship in which the utility model product is usually placed when in use, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0031] In addition, the term "same" does not mean that the parts must be absolutely the same, but slight differences are allowed. The term "vertical" only means that the positional relationship between the parts is more vertical than "parallel", and does not mean that the structure must be completely vertical, but can be slightly tilted.

[0032] See also Figure 1-5 The utility model provides a technical solution: a clamping device for safe production of dangerous goods in chemical industry, comprising a clamping part 1 and a driving part 2 for driving the clamping part 1 to clamp, the clamping part 1 comprising two clamping plates 101, a plurality of empty slots are arranged on the opposite side of the two clamping plates 101, an elastic connecting member 102 is arranged in the empty slot, one end of the elastic connecting member 102 is connected to the empty slot, and the other end extends outside the empty slot and is connected to a rubber block 3.

[0033] In this solution, the driving part 2 is used as a power source to drive the two clamping plates 101 to gradually expand or close, and to clamp dangerous objects of different sizes according to the expansion or closing amplitude. When clamping, the elastic potential energy of the elastic connecting member 102 pushes the rubber block 3, so that the rubber block 3 can better fit the surface of the dangerous object.

[0034] When in use, the driving unit 2 drives the two clamps 101 to move relative to each other, so that the two clamps 101 are relatively expanded or closed. In the expanded state, the two clamps 101 are moved to the dangerous objects, and the dangerous objects are placed between the two clamps 101. At this time, the driving unit 2 drives the two clamps 101 to close, so as to clamp the dangerous objects.

[0035] During the clamping process, the rubber block 3 is in extrusion contact with the dangerous object, and according to the shape of the dangerous object (such as cylindrical, square, etc.), the rubber blocks 3 at different positions are squeezed to different degrees, and the elastic connector 102 is compressed by squeezing the rubber blocks 3. In this state, multiple rubber blocks 3 are convenient to fit on the surface of the dangerous object, thereby enhancing the stability during clamping;

[0036] When the rubber block 3 is in squeeze contact with the dangerous object, the high friction coefficient of the rubber material enhances the anti-slip effect between the rubber block 3 and the dangerous object.

[0037] In this embodiment, a mounting shell 4 is further included, one side of the mounting shell 4 is provided with an opening, one end of the two clamping plates 101 is slidably fitted in the opening, and the driving part 2 is located in the opening and slidably fits with the two clamping plates 101;

[0038] A gripping portion 5 is provided on a side of the mounting shell 4 away from the opening.

[0039] The mounting shell 4 serves as a carrier of the clamping device. The clamping actions of the clamping device on the dangerous goods are all a series of mechanical movements on the mounting shell 4. The gripping portion 5 makes it easy for the user to pick up the device, thereby approaching the dangerous goods and clamping them.

[0040] In this embodiment, the holding portion 5 includes a holding tube 501 and a connecting tube 502, one end of the connecting tube 502 is fixedly connected to the mounting shell 4, the holding tube 501 is sleeved on the end of the connecting tube 502 away from the mounting shell 4, and a clamping piece is provided between the holding tube 501 and the connecting tube 502, and the clamping piece is used for detachable connection between the holding tube 501 and the connecting tube 502.

[0041] The gripping tube 501 serves as a space for the end of the connecting tube 502 to extend, so that the connecting tube 502 can be inserted into the gripping tube 501;

[0042] By inserting the end of the connecting tube 502 into the holding tube 501 at different depths and fixing the connecting tube 502 and the holding tube 501 with a clamping piece, the overall length of the holding portion 5 can be adjusted to facilitate clamping of relatively far or near objects.

[0043] In this embodiment, the card connector includes an elastic card buckle 6 and multiple card interfaces 601. The card interfaces 601 are opened on the holding tube 501, and the multiple card interfaces 601 are arranged along the length direction of the holding tube 501. The elastic card buckle 6 is arranged on the connecting tube 502 and is opposite to the card interface 601. The elastic card buckle 6 can be extended and retracted along the perforation direction of the card interface 601.

[0044] The elastic buckle 6 is clamped in any clamping interface 601 to fix the connection tube 502 and the holding tube 501. When the length needs to be adjusted, the elastic buckle 6 is pressed to press it under the clamping interface 601 to disengage it from the clamping interface 601, thereby adjusting the connection tube 502 and the holding tube 501.

[0045] The elastic buckle 6 has elastic potential energy. After the pressure on the elastic buckle 6 is released, if the elastic buckle 6 is opposite to the card interface 601, the elastic potential energy is released, and the elastic buckle 6 extends from the card interface 601 to be engaged.

[0046] In this embodiment, the driving part 2 includes an extrusion block 201 and two movable blocks 202. The two movable blocks 202 are respectively fixedly connected to one end of the two clamping plates 101 located in the opening. One end of the movable block 202 close to the clamping plate 101 gradually shrinks toward the other end. The two ends of the extrusion block 201 are respectively in contact with the opposite sides of the two movable blocks 202.

[0047] A T-shaped guide bar 2021 is disposed on one side of the movable block 202 close to the extrusion block 201 , and guide grooves 2011 adapted to the guide bar 2021 are disposed at both ends of the extrusion block 201 .

[0048] The two ends of the extrusion block 201 and the side walls of the two movable blocks 202 are relatively inclined. Through the inclined cooperation between the side walls, when the extrusion block 201 moves forward, the two ends of the extrusion block 201 squeeze the two movable blocks 202, so that the two movable blocks 202 move in a relatively away direction, so that the two clamping plates 101 are gradually unfolded;

[0049] By inserting the guide bar 2021 into the guide groove 2011, the guide bar 2021 can only move along the length direction of the guide groove 2011. Therefore, when the extrusion block 201 moves backward, the guide bar 2021 on the extrusion block 201 cooperates with the guide groove 2011 to pull the two movable blocks 202 together, so that the two movable blocks 202 move in a relatively close direction, prompting the two splints 101 to gradually close.

[0050] In this embodiment, the driving part further includes a push-pull rod 203 , which is located in the connecting tube 502 , one end of which passes through the mounting shell 4 and is connected to the extrusion block 201 , and the other end of which extends to the outside of the holding tube 501 .

[0051] When in use, the user pushes or pulls the push-pull rod 203 to move it forward or backward. Because its end is fixedly connected to the extrusion block 201, the extrusion block 201 is driven to move synchronously, so that the extrusion block 201 moves forward or backward in the mounting shell 4.

[0052] In this embodiment, the push-pull rod 203 includes an internal threaded sleeve 2031 and a threaded rod 2032. One end of the threaded rod 2032 passes through the mounting shell 4 and is connected to the extrusion block 201, and the other end is threadedly matched with the internal threaded sleeve 2031. A rotating handle 2033 is provided at the end of the internal threaded sleeve 2031 away from the threaded rod 2032.

[0053] The user rotates the rotating handle 2033 to rotate the internal threaded sleeve 2031. Due to the threaded fit between the threaded rod 2032 and the internal threaded sleeve 2031, the overall length of the push-pull rod 203 is adjusted. Accordingly, when the length is adjusted according to the grip 5, the push-pull rod 203 is adaptively adjusted. On the other hand, the length of the push-pull rod 203 is adjusted until a comfortable clamping force is reached, and the adjustment is completed. The user can then push or pull the rotating handle 2033.

[0054] In this embodiment, a return spring 7 is further disposed in the mounting shell 4 . The return spring 7 is sleeved on the threaded rod 2032 and two ends of the return spring 7 are respectively in contact with the extrusion block 201 and the mounting shell 4 .

[0055] By setting the return spring 7, the return spring 7 pushes the squeezing block 201 in the naturally expanded state, so that the squeezing block 201 squeezes the two movable blocks 202, thereby prompting the two clamping plates 101 to be in the expanded state in the natural state. When clamping is needed, the user just pulls the push-pull rod 203.

[0056] 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 the 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.
