as shown in fig. 1-one of the utility models described herein,

referring to fig. 1 and 2, when the length of the corrugated pipe cannot meet the requirement, a new corrugated pipe needs to be newly added on the basis of the length of the corrugated pipe, so as to achieve the purpose of increasing the length of the total corrugated pipe, and the existing mode of connecting two sections of independent corrugated pipe is mostly implemented by externally connecting a two-way pipe, but because the specification of the two-way pipe and the corrugated pipe are not necessarily adapted, the two-way pipe cannot be connected in real time, and after the two-way pipe and the corrugated pipe are connected, the two-way pipe and the corrugated pipe are not of the same type, the sense of people also has an abrupt sense, in order to solve the problem, in the embodiment, the rapidly-connected corrugated pipe comprises a first corrugated pipe section 1 and a second corrugated pipe section 2, wherein one end, which is close to each other, of the first corrugated pipe section 1 and the second corrugated pipe section 2 is respectively provided with a first extension wall 12 and a second extension wall 23, the first extension wall 12 is sleeved in the second extension wall 23, and the first extension wall 12 and the second extension wall 23 are concentrically arranged, and a limit part 3 is arranged between the first extension wall 12 and the second extension wall 23; the two sections of independent corrugated pipes can be connected through the mode of inserting the sleeve between the first extending wall 12 and the second extending wall 23, and meanwhile, the circumferential rotation between the two sections of corrugated pipes can be limited through the arrangement of the limiting part 3.

It should be noted that, in the above description, the first extension wall 12 and the second extension wall 23 are concentrically disposed, and the purpose of the concentric disposition is to ensure that the first bellows and the second bellows are in a concentric state after being connected, so as to ensure that the liquid flow therein is kept in a normal state.

It should be noted that the first bellows segment 1 is in clearance fit with the second bellows segment 2; through clearance fit's mode can guarantee to make above-mentioned spacing portion 3 better carry out spacingly to the two to can effectually carry out waterproof processing.

Referring to fig. 3 and 4, the specific structure of the limiting portion 3 is as follows: the limiting part 3 comprises a plurality of limiting convex blocks 31 which are arranged on the outer wall of the first extension wall 12 and distributed in an array manner, a plurality of guide grooves 32 for the plurality of limiting convex blocks 31 to slide horizontally along the axial direction of the second corrugated pipe section 2 are formed in the inner wall of the second extension wall 23, one side, far away from the limiting convex blocks 31, of the guide grooves 32 is circumferentially cut along the inner wall of the second corrugated pipe section 2 to form a rotating groove 33, and a plurality of clamping grooves 34 for clamping the limiting convex blocks 31 are formed between every two guide grooves 32 of the rotating groove 33; through setting up of spacing lug 31 and guide chute 32, can guarantee that first extension wall 12 is when stretching into second extension wall 23 in, its circumferential rotation is spacing, can make first extension wall 12 effective plug bush get into in the second extension wall 23, and when spacing lug 31 continues to slide, spacing lug 31 can be close to rotation groove 33 gradually, when spacing lug 31 enters into rotation groove 33 in, first extension wall 12 releases circumferential rotation's spacing this moment, at this moment first extension wall 12 can carry out circumferential rotation in second extension wall 23, and through carrying out circumferential rotation with first extension wall 12 reached make spacing lug 31 be close to the joint groove 34 that is linked together with rotation groove 33 constantly, after spacing lug 31 is close to joint groove 34, with first bellows and second bellows each other separation, spacing lug 31 is in joint groove 34 this moment, until spacing lug 31 can't continue to slide in joint groove 34, at this moment between first bellows and the second bellows circumference and the axial direction that keeps away from each other are both spacing mutually, just also reached between them.

Referring to fig. 4, the specific structures of the middle guide chute 32, the rotation chute 33, and the engagement chute 34 are as follows: in this embodiment, four guide grooves 32 and four clamping grooves 34 are provided, which means that four limit protrusions 31 are also provided on the outer wall of the first extension wall 12; meanwhile, the clamping grooves 34 are arranged between every two guide sliding grooves 32, namely four clamping grooves 34 and four guide sliding grooves 32 are sequentially arranged, and the sizes and the shapes of the clamping grooves 34 are matched with those of the limiting protruding blocks 31.

It should be noted that, when the limiting projection 31 is located in the clamping groove 34, the first bellows segment 1 and the second bellows segment 2 cannot be further away from each other, but still can be close to each other, and in order to make the direction of the two approaching to each other be limited, in this embodiment, a locking member for locking the first bellows segment 1 and the second bellows segment 2 is provided on the second extending wall 23; the omnibearing limit of the first corrugated pipe section 1 and the second corrugated pipe section 2 can be achieved through the arrangement of the locking piece, and further, the first corrugated pipe section 1 and the second corrugated pipe section 2 after connection can form a section of continuous whole.

In addition, the concrete structure of the middle locking piece is as follows: the locking piece comprises a locking nut 21 which is connected with the second extension wall 23 in a threaded manner, and a first annular protruding block 11 for limiting the horizontal sliding of the locking nut 21 is arranged on one side of the first extension wall 12 away from the second extension wall 23; the purpose of enabling the lock nut 21 to rotate on the second extension wall 23 can be achieved through the arrangement of the lock nut 21, and the lock nut 21 can be gradually moved close to or away from the first corrugated pipe section 1 through rotation, meanwhile, due to the fact that the first annular protruding block 11 is arranged on the first corrugated pipe section 1, when one end of the lock nut 21 is close to and abuts against the first annular protruding block 11, the first corrugated pipe section 1 and the second corrugated pipe section 2 are limited in the direction away from each other.

Referring to fig. 3 and 4, in order to facilitate the use of the lock nut 21, the lock nut 21 is disposed on the second extension wall 23 in a threaded connection manner, and after the first bellows segment 1 and the second bellows segment 2 are separated, the lock nut 21 is screwed to achieve the purpose of releasing the lock nut 21, thereby facilitating the replacement or disassembly of the lock nut 21.

In order to ensure that the lock nut 21 does not slide on the second extension wall 23 in a reverse or over-travel manner, a second annular projection 22 is provided on the side of the second extension wall 23 facing away from the first extension wall 12, the second annular projection 22 being located on the side of the lock nut 21, and the second annular projection 22 having a larger diameter than the lock nut 21; the maximum distance the lock nut 21 is away from the first bellows segment 1 when it is rotated is when one end of the lock nut 21 abuts against the second annular projection 22, which is a reverse limit position of the lock nut 21.

Meanwhile, in order to ensure the tightness after the first bellows section 1 and the second bellows section 2 are connected, in this embodiment, a water stop gasket is disposed in the second extension wall 23; by providing a water stop gasket, a better sealing effect between the second extension wall 23 and the first extension wall 12 can be achieved.

It should be emphasized that the examples described herein are illustrative rather than limiting, and therefore the utility model is not limited to the examples described in the detailed description, but rather falls within the scope of the utility model as defined by other embodiments derived from the technical solutions of the utility model by those skilled in the art.
