[0001] The utility model mainly relates to the technical field of corrugated pipes, and in particular to an anti-falling corrugated pipe. Background Art

[0002] Bellows refers to a tubular elastic sensitive element connected by foldable corrugated sheets along the folding and stretching direction. Bellows are widely used in instruments and meters. Their main purpose is to be used as a measuring element of pressure measuring instruments to convert pressure into displacement or force. The wall of the bellows is thinner and the sensitivity is higher. The measuring range is from tens of Pa to tens of MPa. Its open end is fixed, the sealed end is in a free state, and an auxiliary spiral spring or reed is used to increase the elasticity.

[0003] The inventor discovered the following defects during the operation of the specific embodiment:

[0004] During the installation and use of the existing bellows, the bellows may easily become loose due to the loose connection, thereby falling off. At the same time, the firmness of the connection will also have a certain impact on the sealing of the bellows.

[0005] It should be noted that the above contents belong to the technical cognition scope of the inventor. Since the technical contents in this field are vast and too complicated, the above contents of this application do not necessarily constitute prior art. Utility Model Content

[0028] See attached Figure 1-3A kind of anti-falling corrugated pipe comprises a bellows 1, one end of the bellows 1 is connected to a connecting ring 2, one side of the connecting ring 2 is connected to an external connecting cover 3, the external threaded sleeve of the external connecting cover 3 is provided with an internal connecting cover 4, one end of the external connecting cover 3 is connected to a clamping ring 5, a connecting head 6 passes through the inside of the clamping ring 5, the external connecting cover 3 and the internal connecting cover 4 in sequence, the inner wall of the connecting ring 2 is connected to a first sealing ring 7, and the rear end of the inner wall of the external connecting cover 3 is connected to a second sealing ring 8; the middle part of the outer wall of the connecting head 6 is threadedly connected to the rear end of the inner wall of the clamping ring 5, and a clamping assembly is provided between the front end of the outer wall of the connecting head 6 and the front end of the inner wall of the clamping ring 5.

[0029] In this embodiment, the diameter of the second sealing ring 8 is smaller than that of the first sealing ring 7, and a sealing groove 601 is provided at the rear end of the outer wall of the connector 6. The second sealing ring 8 can be limited to the inside of the sealing groove 601, and one end of the connector 6 is in conflict with the side wall of the first sealing ring 7; a groove is provided in the middle of the outer wall of the connector 6, and a thread is provided on the side wall of the groove. The number of threads in the groove at the rear end of the inner wall of the clamping ring 5 and the outer wall of the connector 6 is a specific number of turns when the connector 6 is rotated and fully clamped with the clamping ring 5.

[0030] It should be noted that when one end of the connector 6 enters the inner front end of the clamping ring 5, the connector 6 is rotated so that the thread in the groove on the side wall of the connector 6 cooperates with the thread on the rear end of the inner wall of the clamping ring 5, and the force of rotation causes the inserted end of the connector 6 to come into contact with the side wall of the first sealing ring 7, and the second sealing ring 8 is also limited and engaged in the sealing groove 601, so that the connection between the connector 6 and the bellows 1 has good sealing properties.

[0031] In this embodiment, the snap-on assembly includes four arc-shaped blocks 9, which are evenly distributed at the front end of the outer wall of the connector 6, and four arc-shaped sockets 10 are evenly distributed at the front end of the inner wall of the snap-on ring 5. The arc-shaped sockets 10 are provided with an arc-shaped groove 1001 at one end of the arc-shaped block 9, and the four arc-shaped blocks 9 can be inserted into the corresponding arc-shaped grooves 1001.

[0032] It should be noted that, when the connector 6 rotates, the arc-shaped clamping block 9 on the outer side wall of the connector 6 is also inserted into the arc-shaped clamping groove 1001 after the connector 6 rotates a certain angle.

[0033] In this embodiment, the inner wall of the arc-shaped slot 1001 is connected with a rubber ring 11 , and the rubber ring 11 is sleeved on the outer wall of the arc-shaped clamping block 9 .

[0034] It should be noted that after the arc-shaped clamping block 9 is inserted into the arc-shaped clamping groove 1001 , it is wrapped by the rubber ring 11 on its outer wall, so that the clamping connection between the arc-shaped clamping block 9 and the arc-shaped clamping seat 10 is more firm, thereby improving the anti-falling effect of the corrugated tube 1 .

[0035] The working principle of the utility model is as follows: when using the anti-falling corrugated tube, first, one end of the connector 6 is passed through the interior of the clamping ring 5 and the outer connecting cover 3. When one end of the connector 6 enters the internal front end of the clamping ring 5, the connector 6 is rotated so that the thread in the groove of the side wall of the connector 6 cooperates with the thread at the rear end of the inner wall of the clamping ring 5, and the rotation force causes the inserted end of the connector 6 to conflict with the side wall of the first sealing ring 7, and the second sealing ring 8 is also just limited and engaged in the sealing groove 601, so that the connection between the connector 6 and the corrugated tube 1 has good sealing performance. When the connector 6 rotates, the arc-shaped clamping block 9 on the outer wall of the connector 6 is also inserted into the arc-shaped clamping groove 1001 after the connector 6 is rotated a certain angle, and the number of rotations is just reached at this time, thereby realizing the threaded cooperation between the connector 6 and the clamping ring 5. The arc-shaped clamping block 9 is also wrapped on its outer wall by the rubber ring 11 after insertion, so that the clamping connection between the arc-shaped clamping block 9 and the arc-shaped clamping seat 10 is more firm, thereby improving the anti-falling effect of the corrugated tube 1.

[0036] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the patent of the utility model shall be based on the attached claims.
