Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic pipe joints, and more specifically to a rotatable pneumatic pipe joint. Background Art

[0002] Pipe fittings are connecting tools between pipes and are detachable connection points between components and pipes. Currently, pipe fittings on the market mainly include double joints, elbows, tees, etc., which generally include a fitting body, one end of which is provided with a connector that matches the plastic pipe, and the other end of the fitting body is installed with a fixed internal thread joint. This type of plastic pipe fitting can no longer meet the needs of complex pipe connections on the market. After the pipe fittings and pipe fittings are installed, the pipe fittings cannot be rotated, making them unusable in certain occasions.

[0003] The Chinese utility model disclosed in the prior art with the publication number CN212178176U is a freely rotatable pneumatic pipe joint, in which a bearing body and a rotating body are connected by a bearing so that the rotating body can rotate around the bearing body, and then the pipe fitting at one end of the pipe joint can be rotated in a specific situation by threading the pipe fitting onto the rotating body; however, when the bearing body, the joint body, the rotating body or the bearing is damaged individually, it is difficult to separate the parts and replace them individually, and the maintenance cost is high. In addition, the pipe fitting of the utility model can be separated from the joint body by squeezing a pipe withdrawal button to squeeze the sealing ring away from the pipe fitting to achieve the separation of the pipe fitting. The pipe withdrawal button is easily accidentally touched and squeezed, thereby accidentally causing the pipe fitting to separate, so the present application proposes a rotatable pneumatic pipe joint.

[0039] like Figure 1 and Figure 3As shown, a bottom ring groove 602 is provided on the side of the annular ring 6 close to the joint body 1, a spring groove 102 is provided on the side of the joint body 1 in contact with the annular ring 6, a butterfly spring piece 10 is provided in the spring groove 102, and one end of the butterfly spring piece 10 is against the annular ring 6; an annular thread groove 101 is provided on the side of the joint body 1 in contact with the extrusion ring 3, an annular thread ring 301 is fixedly provided at the position of the annular thread groove 101 on the outer side of the extrusion ring 3, the annular thread groove 101 is threadedly connected with the annular thread ring 301, a top 21 is fixedly provided on the side of the extrusion ring 3 away from the annular ring 6, and a handle 22 is fixedly provided on the side of the top 21 away from the extrusion ring 3; a sealing ring groove 20 is provided at the position of the joint body 1 corresponding to the connection part 9 and a sealing ring 19 is clamped in the sealing ring groove 20.

[0040] Through the above settings, the setting of the bottom ring groove 602 of the utility model enables the convex ring 603 to move to one side of the bottom ring groove 602 when the extrusion ring 3 extrudes the annular ring 6, so that the convex ring 603 leaves the groove 201, thereby making the connecting pipe 2 and the joint body 1 separable; the setting of the handle 22 of the utility model enables the extrusion ring 3 to be rotated by simply rotating the handle 22 when it is necessary to rotate the extrusion ring 3; the setting of the sealing ring 19 of the utility model strengthens the sealing between the joint body 1 and the connecting part 9, and between the bottom sleeve 4 and the connecting part 9.

[0041] Working principle: During installation, the connecting pipe 2 can be directly inserted into one side of the joint body 1 until the convex ring 603 is stuck in the groove 201, and the installation of the connecting pipe 2 can be realized. When the connecting pipe 2 needs to be taken out, the extrusion ring 3 can be rotated by the handle 22, so that the extrusion ring 3 is squeezed toward the annular ring 6, so that the side of the annular ring 6 provided with the convex ring 603 is squeezed toward the side of the bottom ring groove 602, thereby leaving the groove 201, and the connecting pipe 2 can be taken out.

When installing the connecting part 9, it is only necessary to insert the connecting part 9 into the lower end of the joint body 1, and the joint body 1 will squeeze the card block 16 into the embedded groove. When the card block 16 corresponds to the corresponding card slot, the elastic force of the spring 12 will squeeze the card block 16 into the card slot to fix the connecting pipe 2. When taking it out, it only needs to be taken out with the reverse force. When installing the rotating part , it is only necessary to insert the top sleeve 5 first, combine the top sleeve 5 with the semicircular ring 7 through the semicircular ring 7 so that the ring clamping ring 702 is respectively clamped in the ring clamping groove 11, and then the bolts are passed through the auxiliary plate 701 to achieve fixation, and then the bearing 13 is placed in the annular groove 18, and then the fixed side plate 801 is placed in the fixed groove 901 and fixed by bolts to achieve resistance against the bearing 13, and finally the bottom sleeve 4 is inserted, so that the convex portion 501 of the top sleeve 5 is clamped in the concave portion 401 of the bottom sleeve 4, and the clamping block 16 is clamped in the clamping groove to be fixedly connected. The above arrangement facilitates the subsequent removal, maintenance and replacement of each component, effectively reducing the maintenance cost. The arrangement of the bearing 13 also allows the rotating part to rotate, so that the pipe fitting at one end of the pipe joint can be rotated in specific occasions; the bearing 13, spring 12, butterfly spring 10, and sealing ring 19 of the utility model are all disclosed in the prior art, so they are not described in detail.

[0042] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above embodiments.
