Adjustable clamping device

The present invention relates to an adjustable clamping device, and more particularly to an adjustable clamping device for holding an oil filter.

The conventional adjustable clamping device is known from the patent TW 421117, which is provided with a linkage mechanism and two springs between a pair of clips, so that the pair of clips can be close to each other or away from each other to clamp an oil filter. In order to facilitate the disassembly or assembly of the oil filter, the adjustable clamping device of this structure not only has a large number of components, but also is difficult to assemble, resulting in an increase in manufacturing cost, and if the oil filter is to be clamped to a larger size. When the device is used, the two springs may be elastically fatigued due to excessive stretching, so that the clamping effect is lowered and the oil filter cannot be firmly clamped, so that the oil filter may not be firmly clamped. The process of disassembly or assembly is laborious and inconvenient. The structure of the conventional adjustable clamping device is still unsatisfactory and remains to be discussed by the industry.

The purpose of this creation is to provide an adjustable clamping device that can be used to hold the oil filter for disassembly.

In order to achieve the above object, the present invention provides an adjustable clamping device comprising a body, a first clamping block and a second clamping portion.

The body includes a base and a rotating portion, the base has at least one curved slip The rotating portion is rotatably disposed on the base and has at least one sliding member. The rotating portion is rotatable about a rotating shaft and the sliding member is not located on the rotating shaft. The body defines a first direction. The first direction has a first one of the first end and a second end.

The first clamping block is disposed on the base, and the first clamping block is movable along the first direction Sliding between a first position and a second position, the first position being closer to the first end, the second position being closer to the second end, the first clamping block having a first curved hole In the arc chute, the center of curvature of the first arcuate hole is closer to the second end, and the center of curvature of the arc chute is closer to the first end, and the first arc hole and the arc The chute is located between the centers of the two curvatures.

The first clamping block and the second clamping portion respectively have a clamping arm, the first clamping Forming a clamping space between the clamping arm of the block and the clamping arm of the second clamping portion, wherein when the rotating portion rotates relative to the base, the sliding member simultaneously faces the curved sliding slot and the first curved shape The hole moves to drive the first clamping block to slide relative to the base between the first position and the second position, and the width of the clamping space becomes smaller when the first clamping block moves toward the first position. The width of the clamping space becomes larger as the first clamping block moves toward the second position.

Thereby, the adjustable clamping device provided by the creation is rotated by the rotating portion The distance between the first clamping block and the second clamping portion can be adjusted to change the width of the clamping space, so that the oil filter of different sizes can be matched, and the components are compared with the conventional techniques. It is relatively simple, not only easy to assemble but also convenient to operate.

In view of the above, more clearly, the opposite ends of the first arcuate chute 111 of the base 11 are located opposite to the opposite ends of the first arcuate hole 21 of the first clamping block 2. The first sliding member 122 is rotated when the rotating portion 12 is rotated relative to the base 11 by the rotating shaft to displace the first sliding member 122 from one end of the first curved sliding slot 111 to the opposite end. And moving along one end of the first curved hole 21 of the first clamping block 2 to the opposite end to move the first clamping block 2 between the first position and the second position, when the first When the clamping block 2 moves toward the second position, the width of the clamping space becomes larger, and when the first clamping block 2 moves toward the first position, the width of the clamping space becomes smaller. When the first sliding member 122 is displaced to a position in the first curved slot 111, the first sliding member 122 is also located at a midpoint of the first curved hole 21, so that the first The clamping block 2 is located at the second position, that is, the width of the clamping space sandwiched between the first clamping block 2 and the second clamping portion 3 is the largest, and when the first sliding member 122 is When the position of the first curved slot 111 is displaced toward the opposite ends, the first clamping block 2 moves toward the first position and the first clamping block 2 and the second clamping portion 3 Clip The width of the space becomes gradually smaller.

Preferably, in this embodiment, the second clamping portion 3 is slidably disposed on the second clamping portion 3 The second clamping portion 3 has a second curved hole 32. The center of curvature of the second curved hole 32 is closer to the first end than the second curved sliding slot 112. The center of curvature of the second arcuate chute 112 is closer to the second end, and the second arcuate hole 32 and the second arcuate chute 112 are located between the centers of curvature of each other, when the rotating part 12 is opposite to the When the pedestal is rotated, one of the sliding members (ie, the first sliding member 122) can be simultaneously moved along the first curved sliding slot 111 and the first curved opening 21 to drive the first clamping block 2 to Sliding between the first position and the second position, the other sliding member (ie, the second sliding member 123) can simultaneously move along the second curved sliding slot 112 and the second curved hole 32 to drive the The second clamping portion 3 slides relative to the base along the first direction between a third position and a fourth position, the third position being closer to the second end, the fourth position being closer to the first More specifically, the opposite ends of the second curved chute 112 of the base are located at the second curved hole of the second clamping portion 3. Corresponding to the opposite ends of the 32, when the rotating portion 12 is rotated relative to the base by the rotating shaft, the second sliding member 123 is displaced from one end of the second curved sliding slot 112 to the opposite end. The second sliding member 123 is also displaced along one end of the second curved hole 32 of the second clamping portion 3 to the opposite end to enable the second clamping portion 3 to be in the third position and the fourth Moving between positions, when the second clamping portion 3 moves toward the fourth position, the width of the clamping space becomes larger, and when the second clamping portion 3 moves toward the third position, the width of the clamping space changes. Small, in this way, the adjustable width of the clamping space becomes large and can be widely applied to objects of different sizes.

It should be noted that the center of curvature of the first curved chute 111 and the second arc The center of curvature of the chute 112, the center of curvature of the first arcuate hole 21, and the center of curvature of the second arcuate hole 32 are all located in the first direction. When the rotating portion 12 is rotated relative to the base, the The first clamping block 2 and the second clamping portion 3 can be close to or away from each other in the first direction. In other words, when the rotating portion 12 is rotated relative to the base by the rotating shaft, the first sliding member 122 And the second sliding member 123 is simultaneously reversely displaced to cause the first clamping block 2 and the second clamping portion 3 to be close to or away from each other at the same time, when the first clamping block 2 is displaced in the first direction to When the first position and the second clamping portion 3 are displaced to the third position in the first direction, the first clamping block 2 and the second clamping portion 3 are in a collapsed state, when the first position When the clamping block 2 is displaced to the second position in the first direction and the second clamping portion 3 is displaced to the fourth position along the first direction, the first clamping block 2 and the second clamping portion The 3 series is in an expanded state.
