Description

Technical Field

[0001] The utility model relates to the technical field of pipe connectors, in particular to a variable joint accessory. Background Art

[0002] There are generally two types of connection forms for plastic inspection well variable angle joint accessories on the market. One is the snap-on type, where two 22.5° PE structural elbows are connected and assembled through a socket-and-socket buckle with a built-in rubber ring. However, since a water-stop rubber ring is built in after the buckle, the angle cannot be adjusted after the rubber ring is installed. Therefore, they can only be connected as 45° elbows when used on the construction site. The second type is the clamp type, which uses two 22.5° PE structural elbows to hold the rubber ring and fix them together through a clamp, which can also achieve a water-stopping effect, and is more flexible than the previous type; the variable angle function can be achieved on the construction site by adjusting the tightness of the screws on the clamp.

[0003] The two existing products are not convenient for changing angles by cutting, and can only be adjusted by axial rotation. That is, the angle achieved is spatial, and different degrees of height difference will appear when connecting pipes at both ends, affecting the water flow slope. Utility Model Content

[0004] In order to solve the problem that the existing variable angle joint accessories are inconvenient to change the angle by cutting, the utility model provides a variable angle joint accessory, wherein scales and positioning ribs are respectively arranged on the middle pipe section, and the angle can be changed after cutting along the positioning ribs.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] Through the above arrangement, the positioning ribs can increase the strength of the variable joint accessories; after cutting along the positioning ribs, the middle pipe section can be used as a new socket to connect with the pipe to achieve angle change; the axes of the input pipe section, the middle pipe section and the output pipe section are all in the same plane. After the angle change, the variable joint accessories can be placed flat, and there is basically no height difference between the socket and the socket, which is convenient for water flow.

[0008] Furthermore, a slope is provided on one side of the positioning rib facing the input pipe segment, one side of the slope extends to the outer wall of the middle pipe segment, and the other side of the slope is inclined toward the output pipe segment.

[0009] Through the above arrangement, the bevel can guide the blade of the cutting machine to a certain extent, making it easier to cut the intermediate pipe section.

[0010] Furthermore, the cross-section of the positioning rib is a right-angled trapezoid with a height of 4 mm, the lower base of the cross-section of the positioning rib is arranged on the outer wall of the middle pipe section and has a length of 5 mm, one of the waists of the cross-section of the positioning rib is perpendicular to the outer wall of the middle pipe section and is arranged on the side of the positioning rib facing the output pipe section, the other waist of the cross-section of the positioning rib is arranged on an inclined plane, and the length of the upper base of the cross-section of the positioning rib is 3 mm.

[0011] Furthermore, a reinforcing rib is fixedly connected along the inner circumference of one end of the intermediate pipe section away from the input pipe section. The reinforcing rib is arranged on the side of the positioning rib close to the input pipe section. In the axial direction of the intermediate pipe section, the shortest distance from the reinforcing rib to the positioning rib is greater than 8 mm.

[0012] Through the above arrangement, the reinforcing ribs can prevent the middle pipe section from being deformed when the cutting machine is in the middle pipe section; when the shortest distance from the reinforcing ribs to the positioning ribs is greater than 8mm, it can prevent the cutting knife from hitting the reinforcing ribs when the cutting machine cuts the middle pipe section.

[0013] Furthermore, the number of the intermediate pipe sections is three, and from the input pipe section to the output pipe section, the angles between the axes of the intermediate pipe sections and the axes of the input pipe sections are 15°, 22.5°, and 30°, respectively.
