Abstract

The utility model relates to a pipe clamp, which provides quick and steady supporting, assembling and disassembling of a pipe. The utility model is advantageous to the cutting processing. The utility model makes an n-shaped screw rod go forward and fall back mainly through internal screw threads. A tee rotating drum is arranged at one side of a rack body. The internal screw threads are arranged in the tee rotating drum. The n-shaped screw rod can only do straight-line motion. So the n-shaped screw rod is forced to pull a triangle supporting sheet to do inward motion and outward motion. The triangle supporting sheet is embedded in a slot of the n-shaped screw rod. The triangle supporting sheet is coated on a pyramidal expanding pipe. So the pipe sheathed in the triangle supporting sheet can be tightly supported and loosened. The utility model has novelty, advancement, practicality and use value.

Description

pipe clamp

The utility model relates to a kind of pipe clamp, it mainly is used in the taper expander of the set Jiong type screw rod pulling opposite side that only can moving linearly of the T type rotating cylinder of support body one side and its internal female, and the support sheet that makes its peripheral hardware be able to outwards the support folder or in contract convenient fixing or dismounting when making pipe processing.

General common pipe is fixed, all in folder mode beyond the claw with the pipe clamping, right this kind clamp structure, complex structure not only, quite inconvenience of operation clamping, and more can't be with the firm clamping of pipe, moreover, because the restriction of this structure, more influence the processing of pipe, this disadvantages not only makes cost improve, more cause the many unpractical puzzlements of the producer and consumer, never have any innovation structure for a long time and break through.

For overcoming above-mentioned disappearance, main purpose of the present utility model is to provide a kind of pipe clamp, and it can make pipe add man-hour in loading and unloading, and is quite quick and convenient, firmly certain again.

See also shown in Fig. 2 A, the 2B, be the positive back view of three-dimensional combination of the present utility model, support body 1 is fixed into one with fixed block 17, rotating shaft 23, axle sleeve 24, portable plate 25, baffle plate 26 as can be seen, and by positioning seat 27, the clamping part that taper expander 28, stepped extension rod 29, support sheet 3, spring 31 constitute is then by taper hole 231 and alignment pin 234 chimeric are integral of the L type locating slot on the cone 275 of positioning seat 27 1 sides 276 with rotating shaft 23; Then T type rotating cylinder 16 is fixing as for the outside of support body 1 by screw 14 and Jiong type lid 15, and be arranged on the open-work 162 on the T type rotating cylinder 16, in order to its rotation by lever 131, locking bar 13.

See also shown in Figure 3, be combination section of the present utility model, lever 131 is located at it on locking bar 13 by nut 133, locking bar 13 then is located on the open-work 162 of T type rotating cylinder 16,161 spiral shells of internal thread of T type rotating cylinder 16 inside are provided with Jiong type screw rod 2, by the open-work 151 of screw 14 with Jiong type lid 15 and

support body

1,12 and the open-work 172 of being located at the fixed block 17 of support body 1 opposite side wear, and be set as a fixed body with screw 235 spiral shells that a side is provided with the rotating shaft 23 of baffle plate 26, be provided with the positioning seat 27 of cone 275 as for 231 sheathed ends of the taper hole in the rotating shaft 23, and utilize that 276 embeddings of set L type locating slot are integral on the alignment pin established in the former 234 and the latter's the cone 275, and positioning seat 27 central authorities establish a taper expander 28,292 caulking groove 21 embeddings with Jiong type screw rod 2 of the loose tongue that its stepped extension rod 29 ends are established are integral, pin 273 in the pin-and-hole 272 on the stepped extension rod 29 on 291 of set long caulking grooves and the positioning seat 27 is fixed into one, be provided with in addition on the slot 271 in positioning seat 27 outsides by spring 31 and wear several triangle support sheets 3 that are coated on the

taper expander

28, and 26 on rotating shaft 23 and baffle plate is fixing, then pass the latter's open-work 261, and screw togather with the former screw 232 and to be integral by screw 262.

See also shown in Figure 4, exploded view for clamping part of the present utility model and support body 1, since clamping part by the taper hole 231 of the L type locating slot 276 of the cone 275 of positioning seat 27 ends and rotating shaft 23 and in the alignment pin 234 established be embedded and be integral, so clamping part can be made the transform size of spacing according to different pipes processing diameters.

See also shown in Figure 5, for the utility model not with the profile of pipe 4 effect, it at first is placed in pipe 4 clamping part and is against on the baffle plate 26 and gets final product, and then utilize the rotation of lever 131 and locking bar 13, drive 16 rotations (seeing also shown in Figure 6) of T type rotating cylinder, because T type rotating cylinder 16 is placed in the outside of support body 1 by Jiong type lid 15, so when it rotates, since in the Jiong type screw rod 2 established be subjected to the shotpin 111 of its side elongated slot 22 and support body 1 and fixed block 17 central authorities, 171 backstop, therefore, displacement before and after it only can be done, and then with the loose tongue 292 pulling do front and back displacements of taper expander 28 by stepped extension rod 29 ends of one side, this is because taper expander 28 itself also is subjected to pin 273 effects in the pin-and-hole 272 of long caulking groove 291 and positioning seat 27 on the stepped extension rod 29 in end also can not produce rotation, and only does the front and back displacement; When taper expander 28 during toward a side displacement, the triangle support sheet 3 that wears coating by spring 31 that is about to be located at its outside expands to be opened, and an end of triangle support sheet 3 terminates on the slot 271 of positioning seat 27, so only can be along with these taper expander 28 surfaces are from outside to inside, or translation from inside to outside, and then pipe 4 firm support clampings are fixed, for the carrying out of processing; When pipe 4 is desired to be loosened by clamping part, only T type rotating cylinder must be the rightabout rotation, this moment, taper expander 28 was towards the other direction displacement, force triangle support sheet 3 by the strength of spring 31 interior withdrawal restore shape (situation as shown in Figure 5), so pipe 4 can easily take out.

In sum, the utility model will be commonly used the disappearance of product fully and forgo, true tool Nover practical progressive, and more promote this product use value.
