Detailed Description

To facilitate understanding of those skilled in the art, the present invention is further described below in conjunction with the accompanying drawings and the specific embodiments.

As shown in fig. 1 to 8, a pipe clamp with a hinge structure includes a first member 1 and a second member 2, and the first member 1 is hinged to the second member 2. If the first member 1 is rotated on the second member 2, the first member 1 can be folded or unfolded on the second member 2.

The first component 1 comprises a first clamping plate 12, the integral structure of the first clamping plate 12 is in a shape like a Chinese character 'yi', the second component 2 comprises a second clamping plate 22, the integral structure of the second clamping plate 22 is also in a shape like a Chinese character 'yi', and the first clamping plate 12 and the second clamping plate 22 enclose a clamping area.

Wherein a gripping area refers to an area for placing a tubular to be gripped. The pipe means a hose for transferring fluid. The fluid may be a liquid or a gas. The first clamp plate 12 and the second clamp plate 22 can clamp on both sides of a tubular, respectively, if the tubular to be clamped is placed in the clamping area. When the first member 1 is folded on the second member 2, both ends of the first clamping plate 12 are respectively arranged on both ends of the second clamping plate 22, and the whole structure of the clamping area is in a shape of a straight line. If the first clip 12 is lifted on the second clip 22 when the first member 1 is unfolded on the second member 2, the clamping area is gradually opened. In use, if the gripping area is gradually opened and the first and

second jaws

12 and 22 are released from the tubular, the tubular can be removed from or placed into the gripping area, thereby facilitating the tightening and loosening of the tubular and the removal or placement of the tubular into the gripping area.

In practical use, the first clamping plate 12 is lifted on the second clamping plate 22, the pipe to be clamped is placed on the second clamping plate 22, the first clamping plate 12 is folded on the second clamping plate 22, the pipe can be arranged in the clamping area and clamped by the first clamping plate 12 and the second clamping plate 22, and if the first clamping plate 12 is closer to the second clamping plate 22, the clamping force of the first clamping plate 12 and the second clamping plate 22 on the pipe is larger, and the flow cross section of the pipe is smaller.

In particular, the first component 1 is made of plastic, as is the second component 2. The first component 1 is an integrated piece, the second component 2 is also an integrated piece, and the first component 1 and the second component 2 are both manufactured by adopting an integrated injection molding process.

The first member 1 comprises a pawl 14 and a resilient arm 15, the second member 2 comprises a ratchet bar 24, the resilient arm 15 forces the pawl 14 to engage the ratchet bar 24, and the pawl 14, the ratchet bar 24 and the resilient arm 15 form a ratchet mechanism for blocking the first clamping plate 12 from being opened on the second clamping plate 22.

Herein, the ratchet mechanism refers to a movement mechanism that prevents the first member 1 from rotating reversely on the second member 2 and allows the first member 1 to rotate only in one direction on the second member 2. The ratchet mechanism does not prevent the first jaw 12 from moving in a direction to fold over the second jaw 22, but does prevent the first jaw 12 from moving in a direction to open over the second jaw 22.

In actual use, the pipe to be clamped is placed in the clamping area, the first clamping plate 12 is driven to fold on the second clamping plate 22, the pipe can be clamped between the first clamping plate 12 and the second clamping plate 22, and the ratchet mechanism prevents the first clamping plate 12 from being opened on the second clamping plate 22 and prevents the pipe from driving the first clamping plate 12 of the pipe clamp with the hinge structure to be opened on the second clamping plate 22.

In the utility model, the ratchet mechanism plays a role of reverse locking, a user only needs to push the first clamping plate 12 to be close to the second clamping plate 22, the clamping area between the first clamping plate 12 and the second clamping plate 22 can be reduced, then the pipe fitting in the clamping area is clamped, so that the flow area of the pipe fitting is reduced, if the user applies force to the power arm 16, the pawl 14 on the driving elastic arm 15 is separated from the ratchet rack 24, the first clamping plate 12 can be lifted on the second clamping plate 22, so that the flow area of the pipe fitting is increased, the pipe fitting is conveniently taken and placed from the clamping area, and therefore, the pipe fitting clamp with the hinge structure has the advantages of adjustable flow rate of the pipe fitting, simplicity and convenience in operation, simple structure and firm connection.

Specifically, the first clamping plate 12, the elastic arm 15 and the pawl 14 are integrally formed together, the elastic arm 15 is disposed on the outer side of the first clamping plate 12, and the pawl 14 is disposed on the outer end of the elastic arm 15. The ratchet bar 24 and the second member 2 are integrally formed together. The number of parts is reduced, and the cost is reduced.

Specifically, the pawl 14 is curved such that if the first member 1 is rotated on the second member 2, the pawl 14 can move on the ratchet bar 24 and the ratchet bar 24 can engage different positions on the pawl 14 such that the pawl 14 can remain engaged on the ratchet bar 24 at all times during the rotation of the first member 1 on the second member 2.
