Description

Technical Field

[0001] The utility model relates to the field of pipeline connectors, in particular to a pipeline connector with anti-loosening function. Background Art

[0002] At present, there are more and more high-rise buildings. When laying building water supply and drainage pipelines, high-altitude operations are often required. Since the drainage pipelines need to be vertically laid at a relatively high height, it is necessary to use drainage pipe clamps to fix the drainage pipelines at regular intervals.

[0003] The current drainage pipe clamps are all composed of two semi-circular pipe clamps. One of them with a fixing structure is called a fixed pipe clamp, and the other is called a sliding pipe clamp. During installation, select a position to install the fixing structure of the fixed pipe clamp on the wall, and make the fixed pipe clamp buckle on the drainage pipe. Then buckle the sliding pipe clamp on the drainage pipe, and then connect the fixed pipe clamp and the sliding pipe clamp into one body to complete the installation.

[0004] Currently, the fixed pipe clamp and the sliding pipe clamp are fixed by bolts or screws, that is, bolt holes or screw holes are provided on both of them. After buckling both of them on the drainage pipe, the drainage pipe can be fixed by bolts or screws. Such threaded parts are prone to loosening after external vibration, further affecting the fixing effect of the drainage pipe clamp.

[0005] In summary, it is obvious that the prior art has inconveniences and defects in actual use, so it is necessary to be improved. Content of the Utility Model

[0006] Aiming at the above defects, the purpose of the utility model is to provide a pipeline connector with anti-loosening function, which can rotate and position the positioning member through a locking member arranged on the pipe clamp, avoiding its reverse rotation caused by external forces (such as earthquakes and other factors), and further causing the pipe clamp to loosen.

[0007] To achieve the above purpose, the utility model provides a pipeline connector with anti-loosening function, including a pipe clamp with a buckling end and a rotating connector for connecting the buckling ends; ear plates are respectively arranged on the buckling ends; the rotating connector includes a threaded shaft with a positioning block at the end and a positioning member screwed on the threaded shaft; during positioning, the rotating positioning member cooperates with the positioning block to drive the relative movement between the ear plates; a locking member for locking the rotation angle of the positioning member is arranged on the pipe clamp; a fitting groove for inserting the locking member is arranged on the outer wall of the positioning member.

[0008] According to the pipeline connector with anti-loosening function of the utility model, the end of the threaded shaft is installed on one of the buckling ends in a hinged manner.

[0009] According to the pipeline connector with anti-loosening function of the utility model, an embedding groove for placing the threaded shaft is arranged on the ear plate of the other buckling end.

[0010] For the anti-loosening pipeline connector according to the present utility model, the locking member is a plug block, and the end thereof is hinged to the outer wall of the pipe clamp.

[0011] For the anti-loosening pipeline connector according to the present utility model, the locking member is a plug block; a slot for inserting the locking member is provided at a predetermined position on the outer wall of the pipe clamp.

[0012] For the anti-loosening pipeline connector according to the present utility model, a torsion spring is provided at the rotational connection of the locking member to make it tend to rotate towards the working state.

[0013] The present utility model provides an anti-loosening pipeline connector, which includes a pipe clamp with a buckling end and a rotational connector for connecting the buckling ends; ear plates are respectively arranged on the buckling ends; wherein, the pipe clamp can be a combined pipe clamp (which includes a fixed pipe clamp with a fixed structure and a sliding pipe clamp cooperating therewith, and the two are connected by a hinged manner). The rotational connector includes a threaded shaft with a positioning block at the end and a positioning member screwed on the threaded shaft (the positioning member adopts an annular structure, and by adopting this structure, the contact area with the locking member can be increased to avoid deformation of the locking member due to excessive force); during positioning, the rotating positioning member cooperates with the positioning block to drive the relative movement between the ear plates, that is, after rotating the positioning member, under the action of screw drive, the distance between the positioning block and the positioning member is shortened, and the two press the corresponding two ear plates to move relatively to realize the locking of the pipe clamp. The connection manners of the threaded shaft, the positioning block and the ear plates can be various. The end of the threaded shaft is installed on one of the buckling ends by a hinged manner, and an embedding groove for placing the threaded shaft is provided on the ear plate of the other buckling end. With this structure, when the locking members (the threaded shaft and the positioning member are in a non-working state, they can still be connected to the pipe clamp, which can effectively avoid the loss of components). The present utility model can perform rotational positioning on the positioning member through the locking member arranged on the pipe clamp to prevent it from rotating reversely under the action of external forces (such as factors like earthquakes), further preventing the pipe clamp from loosening.

Specific embodiments

[0018] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0019] See Figure 1 、 Figure 2 and Figure 3 As shown in, the present utility model provides a pipe connector for preventing loosening. The pipe connector for preventing loosening includes a pipe clamp 1 having a fastening end 11 (the fastening end 11 has two) and a rotating connecting piece 2 for connecting the fastening ends; ear plates 3 are respectively arranged on the fastening end 11; wherein, the pipe clamp 1 can be a deformable integral pipe clamp (its opening and locking are both realized by its own deformation) or a combined pipe clamp as mentioned in this embodiment (it includes a fixed pipe clamp 100 with a fixed structure and a sliding pipe clamp 101 cooperating therewith. In this embodiment, the two are connected by a hinged manner).

[0020] The rotating connecting piece 2 includes a threaded shaft 22 with a positioning block 21 arranged at the end and a positioning piece 23 screwed on the threaded shaft 22 (as shown in the figure, in this embodiment, the positioning piece 23 adopts an annular structure. By adopting this structure, the contact area with the locking piece 4 can be increased to avoid deformation of the locking piece 4 due to excessive force); during positioning, the rotating positioning piece 23 cooperates with the positioning block 21 to drive the relative movement between the ear plates 3, that is, after rotating the positioning piece 23, under the action of screw transmission, the distance between the positioning block 21 and the positioning piece 23 is shortened, and the two press the corresponding two ear plates 3 to move relatively to realize the locking of the pipe clamp. The connection manners of the threaded shaft 22, the positioning block 21 and the ear plate 3 can be various. For example, as shown in this embodiment, the end of the threaded shaft 22 is installed on one of the fastening ends 11 by a hinged manner (in this embodiment, the positioning block 21 is the hinge shaft), and an embedding groove 24 for placing the threaded shaft 22 is arranged on the ear plate 3 of the other fastening end 11. With this structure, when the locking piece (the threaded shaft 22 and the positioning piece 23 are in a non-working state, they can still be connected to the pipe clamp 1, which can effectively avoid the loss of parts). Or, the threaded shaft 22, the positioning block 21 and the ear plate 3 all adopt a completely detachable connection structure, that is, embedding grooves 24 for placing the threaded shaft 22 are arranged on both ear plates 3. During installation, the threaded shaft 22 needs to be assembled first (both ends are placed in the embedding grooves 24).

[0021] To prevent the positioning member 23 from loosening due to external force (i.e., the positioning member 23 rotates in the reverse direction), a locking member 4 for locking the rotation angle of the positioning member 23 is provided on the pipe clamp 1; a mating groove 5 for inserting the locking member 4 is provided on the outer wall of the positioning member 23. During the installation process, after the positioning member 23 is rotated to the pending position, the locking member 4 is inserted into the mating groove 5 to realize the rotational positioning of the positioning member 23.

[0022] Preferably, for the convenience of installing the locking member 4, the locking member 4 is an insertion block, and its end is hinged to the outer wall of the pipe clamp 1. A torsion spring is provided at the rotational connection of the locking member 4 to make it tend to rotate to the working state. During the process of rotating the positioning member 23, the locking member 4 needs to be pressed to avoid interfering with the rotation of the positioning member 23. After the positioning member 23 is rotated and needs to be positioned, the locking member 4 is released, and it springs back into the mating groove 5 under the action of the torsion spring. With the above structure, the locking member 4 is connected to the pipe clamp 1 whether it is in the working state or not, which can effectively prevent the loss of components.

[0023] In another embodiment, the locking member 4 is an insertion block; a slot 41 for inserting the locking member 4 is provided at a predetermined position on the outer wall of the pipe clamp 1. During the positioning operation, one end of the locking member 4 is inserted into the slot 41, and the other end is inserted into the mating groove 5.

[0024] In summary, the present invention provides a pipeline connector for preventing loosening, including a pipe clamp with a fastening end and a rotating connector for connecting the fastening ends; ear plates are respectively provided on the fastening ends; wherein, the pipe clamp can be a combined pipe clamp (which includes a fixed pipe clamp with a fixed structure and a sliding pipe clamp cooperating with it, and the two are connected by a hinged manner). The rotating connector includes a threaded shaft with a positioning block at the end and a positioning member screwed on the threaded shaft (the positioning member adopts an annular structure, and by adopting this structure, the contact area with the locking member can be increased to avoid the locking member being deformed due to excessive force). During positioning, the rotating positioning member cooperates with the positioning block to drive the relative movement between the ear plates, that is, after the positioning member is rotated, under the action of screw transmission, the distance between the positioning block and the positioning member is shortened, and the two press the corresponding two ear plates to move relatively to realize the locking of the pipe clamp. The connection manners of the threaded shaft, the positioning block and the ear plates can be various. The end of the threaded shaft is installed on one of the fastening ends by a hinged manner, and an embedding groove for placing the threaded shaft is provided on the ear plate of the other fastening end. With this structure, when the locking members (the threaded shaft and the positioning member are in a non-working state, they can still be connected to the pipe clamp, which can effectively prevent the loss of components). The present invention can rotate and position the positioning member through the locking member provided on the pipe clamp, and avoid its reverse rotation due to external forces (such as earthquakes and other factors), further preventing the pipe clamp from loosening.

[0025] Of course, the present utility model may also have many other embodiments. Without departing from the spirit and essence of the present utility model, those skilled in the art can make various corresponding changes and modifications according to the present utility model. However, these corresponding changes and modifications should all fall within the protection scope of the appended claims of the present utility model.
