The utility model provides a clamping assembly which is used for fixing an object to be fixed at a preset position.
In an embodiment of the present invention, as shown in fig. 1 to 6, the clamping assembly includes: the base 10 is provided with a clamping side 11 and a mounting side 12 which are arranged oppositely, and the mounting side 12 is used for mounting the fixing component; the first clamping part 20 is fixed on the clamping side 11, and a first threaded hole 21 is formed in the first clamping part 20; a second clamping portion 30 slidably mounted on the clamping side 11 to move in a direction close to or away from the first clamping portion 20, the second clamping portion 30 having a second threaded hole 31 opposite to the first threaded hole 21; the threaded rod 40 is arranged in the first threaded hole 21 and the second threaded hole 31 in a penetrating mode, the threaded rod 40 comprises a first threaded section 41 and a second threaded section 42, the thread turning direction of the first threaded section 41 is opposite to that of the second threaded section 42, the first threaded section 41 is matched with the first threaded hole 21, and the second threaded section 42 is matched with the second threaded hole 31 so that the second clamping portion 30 is driven to be close to or far from the first clamping portion 20 when the threaded rod 40 rotates.
The clamping side 11, i.e. the side of the base 10 facing the clamping object, the mounting side 12, i.e. the side of the base 10 facing the object to be fixed, and the object to be fixed is connected to the mounting side 12 of the base 10 through a fixing assembly, so as to be relatively fixed on the clamping object.
The first clamping portion 20 and the second clamping portion 30 are used for generating a clamping force to clamp a clamped object together. The fixing manner of the first clamping portion 20 and the base 10 is not limited, and the first clamping portion and the base may be integrally formed to reduce the processing difficulty. The specific matching manner of the second clamping portion 30 and the base 10 may be a sliding rail of the sliding chute 14, or a pulley of the sliding chute 14, which is not limited herein, and only needs to be satisfied that the second clamping portion can be close to or far from the first clamping portion 20. The second clamping portion 30 can be close to or far from the first clamping portion 20, so that the distance between the first clamping portion 20 and the second clamping portion 30 can be adjusted according to the size of a clamped object.
The first threaded hole 21 is coaxial with the second threaded hole 31, and the axial directions of the first threaded hole 21 and the second threaded hole 31 are the moving directions of the second clamping portion 30. The first screw hole 21 penetrates the first clamping portion 20, and the second screw hole 31 penetrates the second clamping portion 30, so that the threaded rod 40 can penetrate the first clamping portion 20 and the second clamping portion 30.
The first thread section 41 and the second thread section 42 may be separately provided at both ends of the threaded rod 40. The first thread segments 41 and the second thread segments 42 may be the same length or different lengths, so long as the thread directions are different. It will be appreciated that the thread orientations of the first and second threaded bores 21, 31 should correspond to the first and second thread segments 41, 42, respectively.
For example, the second threaded section 42 is close to the first clamping portion 20 when the threaded rod 40 rotates forward, and the base 10 is used as a motion reference object. When the threaded rod 40 rotates forward, the first threaded section 41 and the second threaded section 42 rotate in the same direction, and at this time, since the first clamping portion 20 is fixed on the base 10, the second threaded section 42 gradually approaches the first clamping portion 20 and drives the second clamping portion 30 to approach the first clamping portion 20 together. In the process of screwing the second threaded section 42 and the second threaded hole 31, since the second clamping portion 30 is movable relative to the base 10, the second clamping portion 30 is driven in a direction close to the first threaded section 41, that is, the second clamping portion 30 is driven to be close to the first clamping portion 20 by the rotation of the second threaded section 42, and the second threaded section 42 is driven to be close to the first clamping portion 20 by the rotation of the first threaded section 41, so that the second clamping portion 30 can be more quickly close to the first clamping portion 20 at the same superposition speed in the two directions, and the time for clamping in place can be shortened. Thus, the user can move the second clamping portion 30 by a double stroke by only rotating the threaded rod 40 by one turn, so as to shorten the operation time of the user and improve the convenience of use of the clamping assembly.
The threaded rod 40 may pass through the base 10, or may be located outside the base 10, which is not limited herein, and only the threaded rod 40 needs to be inserted into the first clamping portion 20 and the second clamping portion 30.
According to the clamping assembly, the two thread sections are arranged on the threaded rod 40, the thread turning directions of the two thread sections are opposite, and then the two thread sections are matched with the threaded holes of the two clamping parts respectively, so that when the threaded rod 40 is rotated in the forward direction, the threaded rod 40 can move axially relative to the first clamping part 20 while rotating relative to the first clamping part 20 because the first clamping part 20 and the base 10 are relatively fixed, and the second thread section 42 moves towards the direction close to the first clamping part 20; the second clamping portion 30 is matched with the second threaded section 42, and the second threaded section 42 and the first threaded section 41 have the same rotating direction and the opposite rotating direction, so that when the threaded rod 40 rotates forwards, the second clamping portion 30 can move, and the second threaded section 42 can drive the second clamping portion 30 to move towards the direction close to the first clamping portion 20; that is, when the threaded rod 40 rotates forward, the second threaded section 42 moves toward the direction close to the first clamping portion 20, and simultaneously the second threaded section 42 drives the first clamping portion 20 to move toward the direction close to the first clamping portion 20 through threaded engagement, so that the first clamping portion 20 can approach the first clamping portion 20 at two superimposed speeds, so as to increase the moving speed of the first clamping portion 20; that is, the threaded rod 40 only needs to rotate forward for one turn to drive the first clamping portion 20 to move for a double stroke, so that the number of turns of the threaded rod 40 rotated by a user can be reduced, and the convenience in use of the clamping assembly is improved.
