Description

Water pipe clamp

The present invention relates to a hand tool for fastening or dismounting, and more particularly to a water pipe clamp.

The existing water pipe clamp structure is shown in FIG. 6 to FIG. 8 , and includes a fixed handle 50 , a movable handle 60 and a pivot shaft 70 . The fixed handle 50 includes a fixing handle 51 , a handle space 52 and a pivot The fixing portion 51 is toothed and disposed at one end of the fixing handle 50. The handle space 52 is formed at the fixing handle 50 near the fixing jaw 51 and forms two sides on the fixing handle 50. An opening 521, the pivoting portion 53 is formed in a long hole shape and is disposed at the fixing handle 50 near the fixing jaw 51, and communicates with the handle space 52; the movable handle 60 is inserted into the handle space 52 and passes through the opening 521, the movable handle 60 includes a movable cymbal 61 and a through hole 62, wherein the movable cymbal 61 is toothed and disposed at one end of the movable handle 60, and the movable cymbal 61 can be correspondingly engaged with the fixed cymbal 51; The pivoting shaft 70 is coupled to the through hole 62 and the movable handle 60 is pivotally disposed on the pivoting portion 53. The pivoting shaft 70 includes a biting area 71, and the biting area 71 is disposed on the pivoting shaft 70 and the The surface of the perforation 62 is combined, and the biting area 71 includes a plurality of convex and convex portions 71 arranged in the warp and weft. 1. The convex portion 711 has a shape with a high middle and a low circumference. When the pivot shaft 70 is coupled to the through hole 62, the convex portion 711 can be tightly fitted to the through hole 62 in a point-like manner. The pivot shaft 70 is firmly coupled to the through hole 62.

However, since each of the convex portions 711 is arranged in a warp and weft shape and bit-shapedly engages the through hole 62, the occlusal area of the pivotal shaft 70 and the through hole 62 is small, when the water pipe clamp is in the process of being transported or used. When the middle is hit, the pivot shaft 70 easily slides out of the through hole 62 and is separated from the movable handle 60, so that it is inconvenient to use.

In order to solve the problem that the pivoting shaft of the existing water pipe clamp is easy to fall off, the main purpose of the present invention is to provide a water pipe clamp which can solve the current technical problems.

In order to achieve the above object, the present invention provides a water pipe clamp, comprising: a fixed handle, comprising a fixing cymbal and a pivoting portion, wherein the fixing cymbal is disposed at one end of the fixed handle, the pivoting portion is disposed at The movable handle is adjacent to the fixed raft; a movable handle includes a movable cymbal and a through hole, wherein the movable cymbal is disposed at one end of the movable handle, and the movable cymbal and the fixed cymbal are correspondingly clamped, the perforation And the pivoting shaft is coupled to the through hole and the movable handle is pivoted on the pivoting portion, wherein the pivoting shaft has a non-circular cross section and The occlusal area includes a plurality of convex portions, a plurality of concave portions and a plurality of connecting portions, and the concave portion is formed on the surface of the through hole. a V-shaped portion, and each of the convex portions and the concave portions are alternately arranged, and are formed on a surface of the pivotal shaft about a longitudinal direction of the pivotal shaft, and each of the convex portions protrudes from the pivotal shaft at the biting area Side surface, each of the connecting portions is connected to the phase Each of the adjacent convex portions is adjacent to each of the concave portions.

In the water pipe clamp, each of the connecting portions is inclined.

Therefore, the achievable effects of this creation by the above technical means are:

1. Since each of the protrusions is V-shaped and protrudes from a surface of the pivoting shaft on both sides of the biting area, each of the protrusions is engaged with the perforation in a plane-like manner, and the pivoting is increased. The shaft axially engages the force of the perforation, and the pivot shaft can be less easily detached from the perforation when a collision is generated.

2. Each of the connecting portions is obliquely connected between the adjacent convex portions and each of the concave portions, thereby increasing the area and strength of the pivoting shaft to engage the through holes.

In order to understand the technical features and practical functions of the present invention in detail, and in accordance with the contents of the specification, further description will be made in detail with reference to the preferred embodiments as illustrated in the following: For example, as shown in FIG. 1 to FIG. 4, the fixed handle 10 includes a fixed handle 10 and a pivoting shaft 30. The fixed handle 10 includes a fixed cymbal 11 and a pivoting portion 12, wherein the fixing The 颔11 is disposed at one end of the fixed handle 10, the pivoting portion 12 is disposed at the fixed handle 10 near the fixed cymbal 11, and the pivoting portion 12 has a long hole shape; the movable handle 20 includes a movable cymbal 21 and a through hole 22, wherein the movable jaw 21 is disposed at one end of the movable handle 20, and the movable jaw 21 can be correspondingly engaged with the fixed jaw 11, the through hole 22 is non-circular and is disposed near the movable handle 20 The activity is at 21; the cross section of the pivot shaft 30 matches the perforation 22 and is combined The pivoting portion 22 is pivotally disposed on the pivoting portion 12 by the pivoting shaft 30. The pivoting shaft 30 is movable within the pivoting portion 12 at a specific angle, so that the movable handle 20 can be adjusted and The relative position of the fixed handle 10 is changed to change the distance between the movable jaw 21 and the fixed jaw 11; wherein the pivot shaft 30 has a semi-circular cross section, and the pivot shaft 30 includes a biting area The occlusal area 31 is disposed on the surface of the through hole 22, and the squeezing area 31 includes a plurality of convex portions 311, a plurality of concave portions 312, and a plurality of connecting portions 313, and the convex portions 311 and The concave portions 312 are all V-shaped, and the convex portions 311 and the concave portions 312 are alternately arranged, and are formed on the surface of the pivot shaft 30 about the longitudinal direction of the pivot shaft 30, and the convex portions 311 are protruded. The connecting portion 313 is connected between the adjacent convex portions 311 and each of the concave portions 312. In the preferred embodiment of the present invention, the pivoting shaft 30 is located on the surface of the two sides of the squeezing portion 31. The connecting portion 313 is obliquely connected between the adjacent convex portions 311 and each of the concave portions 312; wherein the pivot shaft 30 and the movable handle The coupling manner of the first embodiment is that the through hole 22 having the same shape as the cross section of the pivot shaft 30 is inserted between the movable handle 20 and the pivoting portion 12, and the pivoting shaft 30 is directly driven into the through hole 22. The pivoting shafts 311 and the connecting portions 313 are tightly engaged with the through holes 22 , and the protruding portions 311 and the connecting portions 313 are in a planar shape to engage the through holes 22 . The force of the pivot shaft 30 axially engaging the through hole 22 is increased, and the pivot shaft 30 is not easily detached from the through hole 22 when a collision is generated.

In use, the movable handle 20 is rotated by the pivot shaft 30, and the pivot shaft 30 is moved to the pivoting portion 12 at a specific angle, and the adjustment is completed. Then, the movable handle 20 is rotated to lock the pivot shaft 30 at the specific angle to the pivoting portion 12, so that the state shown in FIG. 5 can be completed, so that the water pipe of different pipe diameters can be applied.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way. Anyone having ordinary knowledge in the art can use the present invention without departing from the technical features proposed by the present invention. Equivalent embodiments for making partial changes or modifications made by the technical content disclosed herein, and without departing from the technical features of the present invention, are still within the scope of the present technical features.
