Description

Technical Field

[0001] The utility model relates to the technical field of quick-change joints, in particular to a bend-type quick-change joint. Background Art

[0002] When in use, one end of the pipe is directly inserted into the groove at the bottom of the bent body along the inner wall of the pressure ring and the reinforcing ribs on the bent body, and is clamped in place by the clamping ring to prevent the air pipe from falling out; when unlocking, the pressure ring moves inward to lift the split elastic locking piece on the clamping ring to separate it from the outer wall of the air pipe. At this time, the air pipe and the quick-connect connector can be quickly disassembled. During use, one end of the pressure ring is located outside the connector. During use, there is a possibility that the staff may accidentally touch it and press it directly, which may cause the connector to separate from the pipe during use. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The utility model provides Figure 1-7 A curved pipe quick-change connector shown in the figure includes a connector 1 and a pressure ring 2 on the top of the connector 1, a limiting component 3 for limiting the movement of the pressure ring 2 is arranged on the top of the connector 1; the limiting component 3 includes a rotating ring 301 arranged on the top of the pressure ring 2, a positioning ring 303 is sleeved on the top of the connector 1, a plurality of positioning rods 302 are symmetrically fixedly connected to the bottom of the rotating ring 301, and a plurality of through holes 304 compatible with the positioning rods 302 are symmetrically opened on the top of the positioning ring 303; a connecting component 4 for limiting the rotation angle and movement of the rotating ring 301 is arranged at the connection between the rotating ring 301 and the pressure ring 2, and a positioning component 5 for limiting the moving distance of the positioning rod 302 is arranged at the top of the positioning ring 303 and on one side of the through hole 304.

[0026] It should be noted that the connector 1 and the pressure ring 2 are quick connector threaded elbows of model PL6-M5. The positioning ring 303 can be fixedly sleeved on the top of the connector 1 by bonding or other fixing methods. At least two positioning rods 302 are provided, which are fixed horizontally and centrally symmetrically on the bottom of the rotating ring 301, and the positioning ring 303 is provided with through holes 304 that are consistent with and compatible with the number of positioning rods 302, so that the positioning rods 302 pass through the positioning ring 303 through the through holes 304. When it is necessary to fix the pipe and the connector 1, the positioning rod 302 at the bottom of the rotating ring 301 is moved out of the through holes 304, and the rotating ring 301 is rotated so that the positioning rods 302 and the through holes 304 are aligned. 303, so that the bottom of the positioning rod 302 is blocked by the top of the positioning ring 303, so that the positioning rod 302 and the rotating ring 301 cannot move to one side of the connector 1, and the position of the pressure ring 2 is limited by the rotating ring 301 that limits the movement. When the pressure ring 2 needs to be pressed to one side of the connector 1, the positioning rod 302 is driven by the rotating ring 301 to be aligned with the through hole 304. While pressing the pressure ring 2 and the rotating ring 301, the positioning rod 302 at the bottom of the rotating ring 301 passes through the through hole 304, so that the pressure ring 2 can move to one side of the connector 1. This design limits the movement of the pressure ring 2 to ensure that the connector 1 and the pipeline will not separate during use.

[0027] Specifically, the connecting assembly 4 includes a connecting rod 401 which is centrally symmetrically fixedly connected to the top of the pressure ring 2, a plurality of positioning disks 402 are centrally symmetrically arranged on the top of the rotating ring 301, the positioning disks 402 are fixedly connected to the top of the connecting rod 401, a plurality of through holes 6 are centrally symmetrically opened on the top of the rotating ring 301, the connecting rod 401 is inserted and connected inside the through hole 6, and the horizontal transverse section of the through hole 6 is an arc.

[0028] It should be noted that the diameter of the horizontal transverse section of the positioning plate 402 is larger than the width of the horizontal transverse section of the through hole 6, so that the positioning plate 402 cannot pass through the through hole 6, and the rotating ring 301 with the through hole 6 is restricted between the positioning plate 402 and the pressure ring 2. When the rotating ring 301 needs to be rotated, the rotating ring 301 rotates between the pressure ring 2 and the positioning plate 402, and the connecting rod 401 connecting the positioning plate 402 and the pressure ring 2 rotates in the through hole 6 opened on the rotating ring 301.

[0029] Specifically, the positioning assembly 5 includes a blocking block 501 fixedly connected to the top of the positioning ring 303 , and a fitting groove 502 is provided on one side of the blocking block 501 , and a horizontal transverse cross section of the fitting groove 502 is set to be semicircular.

[0030] It should be noted that the blocking block 501 is used to limit the moving distance of the positioning rod 302. When the rotating ring 301 needs to be pressed, the positioning rod 302 at the bottom of the rotating ring 301 needs to be rotated to align with the through hole 304. The blocking block 501 is set on one side of the through hole 304. When the rotating ring 301 moves to fit with the fitting groove 502 opened on one side of the blocking block 501, the alignment between the positioning rod 302 and the through hole 304 can be completed, thereby avoiding the need for constant observation when aligning the through hole 304 and the positioning rod 302.

[0031] Specifically, the bottom end of the positioning rod 302 is fixedly connected to a rubber pad 7, and a limit assembly 8 is provided at the connection between the rubber pad 7 and the positioning rod 302 to strengthen the connection between the two. The limit assembly 8 includes a limit rod 801 fixedly connected to the bottom end of the positioning rod 302, and a positioning hole 802 is opened in the middle of the rubber pad 7, and the limit rod 801 is inserted and connected to the inside of the positioning hole 802.

[0032] It should be noted that the rubber pad 7 is made of rubber material. When in use, the rubber pad 7 is squeezed between the positioning rod 302 and the positioning ring 303, so that the rubber pad 7 is deformed when located between the positioning rod 302 and the positioning ring 303. After the surface of the rubber pad 7 is squeezed, the gap at the connection between the positioning rod 302 and the positioning ring 303 is filled, thereby generating more contact area, thereby increasing the friction between the bottom end of the positioning rod 302 and the positioning ring 303, and avoiding the positioning rod 302 to slide directly on the positioning ring 303 when not in use; the rubber pad 7 and the positioning rod 302 are fixed by bonding, and the limit rod 801 and the positioning hole 802 are used to strengthen the connection between the rubber pad 7 and the positioning rod 302. The limit rod 801 is pulled to avoid the rubber pad 7 and the positioning rod 302 from separating when there is friction between the rubber pad 7 and the positioning ring 303.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
