Detailed Description
The preferred embodiments of the present utility model will be described below with reference to the accompanying drawings, it being understood that the preferred embodiments described herein are for illustration and explanation of the present utility model only, and are not intended to limit the present utility model.
Example 1.
As shown in fig. 1 to 3, the pipe connection device described in this embodiment includes: the limiting swivel 1, the limiting swivel 1 is used for driving the pipe connection, and the outer lane of the limiting swivel 1 is evenly provided with two rotating supports 2, in this embodiment, the rotating supports 2 are two.
And one end of the rotating piece 3 is connected with the rotating support 2 through a hinge, and the other end is a free end 5.
And at least one locking screw 4, wherein two sections of symmetrical threads are arranged on the inner pipe wall of the locking screw 4 and are used for being in threaded connection with the free end 5 of the rotating piece 3 through the threads.
The limiting swivel 1 is internally matched with a connecting ring 6, an annular step surface 7 formed by two sections of outer diameters is arranged on the outer ring of the connecting ring 6, the limiting swivel 1 is sleeved on a small diameter section 8 of the connecting ring 6, and meanwhile, the axial length of the small diameter section 8 is greater than or equal to that of the limiting swivel 1, preferably, the axial length of the small diameter section 8 is greater than that of the limiting swivel 1, so that the tail end of the small diameter section 8 extends out of the limiting swivel 1, and the limiting swivel is convenient to be connected with an external pipe fitting. On the other hand, when connecting the pipe fitting, the first end surface of the limiting swivel 1 abuts against the annular step surface 7, so that the tensile force borne by the limiting swivel 1 can be transmitted to the connecting ring 6 through the abutting surface.
Meanwhile, the first end surface of the limiting swivel 1 and the annular step surface 7 are provided with mutually matched limiting devices, so that the limiting swivel 1 can drive the connecting ring 6 to rotate together when rotating (not shown in the figure). In some embodiments, the limiting device may be uniformly distributed tooth-shaped clamping grooves, or may be several corresponding protruding points and pits.
The inner wall of the limiting swivel 1, which is close to the second end face, is provided with a clamping ring groove 11, and the clamping ring groove 11 is generally used for being connected with a protruding part of an external pipe fitting so as to ensure the connection of the external pipe fitting and the whole pipeline connecting device and avoid the disconnection of the external pipe fitting and the pipeline connecting device caused by accidents.
The outer wall of the small-diameter section 8, which is close to the end part, is provided with external threads for connecting an external pipe fitting, so that the small-diameter section can be connected with the external pipe fitting through threads, and the connection stability with the external pipe fitting is further ensured.
In some cases, the rotating support 2 is provided with a limiting device, so that the rotating member 3 can only rotate in one direction by taking the hinge point as the center, and can rotate in the direction deviating from the small-diameter section 8 of the connecting ring 6, thereby being more convenient for keeping the rotating member 3 in a 90-degree state and being used as a stress point for rotating the limiting rotating ring 1.
Such pipe connection devices are typically used in pairs.
In some embodiments, two rotating parts 3 are arranged on the limiting swivel 1 of the pipeline connecting device, one rotating part 3 is provided with a locking screw 4, and when the two pipeline connecting devices are connected, the two pipeline connecting devices are symmetrically used in a central mode, and then the two pipeline connecting devices can be butted through the locking screw 4.
In other embodiments, the pipe connection is provided in a male-female arrangement, i.e. both rotational members 3 on the male pipe connection are provided with locking screws 4, whereas the rotational members 3 on the corresponding female pipe connection are not provided with locking screws.
In still other embodiments, the pipe connection is packaged separately from the locking coils 4, and a pair of pipe connection is labeled with two to three locking coils 4 for ease of use in installation.
In particular use, for example, a heating and ventilation valve is mounted on the heating and ventilation pipe, as shown in fig. 4. The heating and ventilation valve and the controller 9 are directly adapted to a section of connecting pipe, and when leaving the factory, the two ends of the connecting pipe are already provided with the pipeline connecting device. After the spot is reached, the corresponding pipeline connecting device is installed on the spot heating through pipe 10, so that the butt joint of the spot heating through pipe 10 and the heating through valve connecting pipe fitting is convenient.
During connection, the limiting swivel 1 is sleeved on the small-diameter section 8 of the connecting ring 6, then a sealing ring is arranged in a gap (a space corresponding to the clamping ring groove 11) between the inner wall of the limiting swivel 1 and the outer wall of the connecting ring 6 from the rear part, and then the sealing ring is connected with the internal thread of the end part of the on-site heating through pipe 10 through the external thread outside the connecting ring 6. When in connection, the limiting swivel 1 is pushed to enable the first end face to be abutted against the annular step face 7, so that the limiting swivel 1 is clamped with the connecting ring 6, and in this state, the rotation of the limiting swivel 1 directly drives the connecting ring 6 to rotate. In order to facilitate the rotation of the limiting swivel 1, the rotating piece 3 can be shifted to a vertical state as shown in fig. 2, so that a spanner-like effect is formed, the connecting ring 6 is in threaded fastening connection with the on-site heating pipe 10, and in the threaded fastening connection process, the on-site heating pipe 10 gradually moves towards the limiting swivel 1 along with the tightening of threads, so that the end flange of the on-site heating pipe 10 can smoothly enter the clamping ring groove 11, the sealing ring can be pressed to a corresponding position, and finally the connection between the pipeline connecting device and the on-site heating pipe 10 is completed.
Then, in order to complete the butt joint of the two pipe connection devices, the limiting swivel 1 can be moved to the direction of the on-site heating pipe 10 first, the limiting connection of the first end face and the annular step face 7 is separated, at this time, the limiting swivel 1 can be rotated independently, and the rear part of the limiting swivel is connected with the on-site heating pipe 10 through the clamping ring groove 11, so that the rotation of the limiting swivel 1 does not cause the torsion of the rear-end on-site heating pipe 10. The rotation of the limiting swivel 1 alone can align the positions of the rotating parts 3 between the two corresponding pipeline connecting devices, and finally the two rotating parts 3 are connected relatively through the threaded connection of the locking screw 4 and the free ends 5 of the rotating parts 3, so that the relative connection of the two pipeline connecting devices is realized.
In addition, in general, two opposite connecting pipe connecting devices are mainly connected by the end of the large-diameter section of the connecting ring 6, and it should be understood to those skilled in the art that the end needs to be formed into a socket-like structure, and if necessary, a sealing ring needs to be disposed at the connecting portion, and the structure of the connecting portion is not repeated here in this embodiment.
