Description

Technical Field

[0001] The utility model relates to the technical field of joint elbows, in particular to a combined anti-static joint elbow. Background Art

[0002] The combined anti-static junction elbow is a pipe connector that combines anti-static function and junction design. It is used in occasions where anti-static protection is required, such as electronics, chemical, pharmaceutical and other industries, to achieve flexible connection and electrostatic protection of the pipeline system.

[0003] A Chinese patent discloses a combined double elbow with publication number CN210978904U, and the application date is 2019.08.22. The patented technology installs or removes the connecting pipe according to the situation to suit different types of elbows. The plug on the elbow is correspondingly plugged into the connecting block. After assembly, the center hole distance of the elbow is 15cm, and it is fixed to the wall by bolts. The utility model has a reasonable design, strong toughness, high compressive strength, strong impact resistance, accurate positioning, and greatly improves work efficiency. However, the above-mentioned device adopts two integrated parallel elbows. During the use of this structure, when one of the elbows or the connecting plate is damaged, it is necessary to replace a new elbow as a whole, which is very wasteful. When encountering pipes of different sizes, the elbow cannot be adjusted, which is easy to affect the construction. Therefore, the inventor provides a combined anti-static parallel elbow to solve the problems raised in the above background technology. Utility Model Content

DETAILED DESCRIPTION

[0021] like Figure 1 As shown, a combined anti-static joint elbow comprises a first elbow 10 and a second elbow 20. A connecting mechanism 30 is provided between the first elbow 10 and the second elbow 20. The connecting mechanism 30 is connected to the first elbow 10 and the second elbow 20 via docking mechanisms 40 provided on the left and right sides, respectively. This achieves the effect of joint elbows.

[0022] Preferably, the outer sides of the first elbow 10 and the second elbow 20 are coated with antistatic materials, such as antistatic paint, antistatic tape, etc., to effectively reduce the risk of static electricity accumulation and discharge. When in use, the first elbow 10 and the second elbow 20 are connected to the joint through a flange.

[0023] refer to Figure 2 、 5 The connecting mechanism 30 includes a connecting box 301, and the left and right sides of the interior of the connecting box 301 are respectively slidably connected with extension blocks 302; the upper and lower sides of the interior of the connecting box 301 are jointly rotatably connected with a threaded rod 303, and the threaded rod 303 is threadedly connected with a sliding block 304, and the left and right sides of the sliding block 304 are respectively rotatably connected with a pair of mirror-symmetrical connecting rods 305 through movable axes; a pair of clamping blocks 306 are fixedly connected to the inner bottom of the extension block 302, and the clamping blocks 306 are rotatably connected to the corresponding connecting rods 305.

[0024] Preferably, the side surface of the extension block 302 matches the cross-section of the connection box 301, thereby guiding the movement of the extension block 302. During use, the threaded rod 303 is rotated, which drives the sliding block 304 up and down, thereby driving the extension block 302 toward or away from each other via the connecting rod 305, thereby adjusting the spacing between the connection mechanism 30. This, in turn, adjusts the spacing between the two elbows, thereby accommodating two joints with different spacings.

[0025] Furthermore, the top of the threaded rod 303 is fixedly connected to an external rotating rod 307. A fixing ring 308 is provided on the outside of the external rotating rod 307. The bottom of the fixing ring 308 is fixedly connected to the connection box 301. A set of positioning holes 309 are formed on the outside of the fixing ring 308. A positioning pin 310 is provided inside the right positioning hole 309. A similar positioning hole 309 is also provided on the right side of the external rotating rod 307. During use, the threaded rod 303 is rotated by rotating the external rotating rod 307, thereby adjusting the length of the connecting mechanism 30. After the positioning hole 309 on the external rotating rod 307 aligns with one of the positioning holes 309 on the fixing ring 308, the positioning pin 310 is then inserted into the two positioning holes 309, thereby securing the threaded rod 303 and, in turn, the position of the extension block 302.

[0026] refer to Figure 3 、 4 The docking mechanism 40 includes a docking frame 401 fixedly connected to the outside of the extension block 302, a fixed block 402 is fixedly connected to the right side of the inside of the docking frame 401, a bolt 404 is threadedly connected to the left side of the docking frame 401, and the bolt 404 is rotatably connected to the movable block 403 through a bearing 405. The inner end of the bearing 405 is fixedly connected to the bolt 404, and the outer end of the bearing 405 is fixedly connected to the surface of the movable block 403.

[0027] Preferably, guide grooves 406 are respectively provided on the front and rear sides of the movable block 403, and turning blocks 407 are fixedly connected to the front and rear sides of the docking frame 401. The turning block 407 is in the shape of a "7", and the top protruding part of the turning block 407 is slidably connected to the guide groove 406, thereby supporting the movable block 403 and guiding it when moving.

[0028] Preferably, the opposing sides of the movable block 403 and the fixed block 402 are inwardly concave arcs. During use, the bolt 404 is rotated, causing it to rotate and simultaneously move outward, driving the movable block 403 outward through the bearing 405, exposing the space between the movable block 403 and the fixed block 402. The corresponding elbow top is then inserted into the inner sides of the movable block 403 and the fixed block 402. The bolt 404 is then rotated in the opposite direction, causing it to move inward, driving the movable block 403 inward until the elbow is clamped and fixed inside the movable block 403 and the fixed block 402. When the elbow needs to be replaced, the same steps are followed: the new elbow is fixed to the docking mechanism 40 and then connected to the docking joint.

[0029] Preferably, an anti-slip layer 408 is provided on the inner side of the movable block 403 and the fixed block 402; after the movable block 403 and the fixed block 402 clamp and fix the elbow, the anti-slip layer 408 contacts the outer surface of the elbow, thereby increasing the clamping and fixing effect of the elbow.

[0030] The working principle of the present invention is as follows: rotate the bolt 404 so that the bolt 404 rotates and moves outward at the same time, driving the movable block 403 to move outward through the bearing 405, exposing the space between the movable block 403 and the fixed block 402, and then inserting the corresponding elbow top into the inner side of the movable block 403 and the fixed block 402; then rotate the bolt 404 in the opposite direction so that the bolt 404 moves inward and drives the movable block 403 to move inward until the elbow is clamped and fixed on the inner side of the movable block 403 and the fixed block 402.

[0031] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
