Abstract
Description
Technical Field
[0001] This utility model belongs to the field of smoke exhaust pipe installation and positioning technology, and in particular relates to a smoke exhaust pipe positioning device. Background Technology
[0002] As a key component for kitchen fume extraction, the range hood exhaust pipe bears the important responsibility of expelling the fumes and exhaust gases absorbed by the range hood to the outside. It effectively prevents fumes from lingering indoors and acts as a barrier to protect family health. It directly affects indoor air quality and residents' health, and the proper installation of the exhaust pipe is crucial for ensuring a safe kitchen environment.
[0003] The portion of the exhaust pipe exposed outdoors in the kitchen is often curved, typically requiring a 90-degree right-angle bend. This is to direct the exhaust outlet downwards, preventing grease from flowing back into the pipe. However, current exhaust pipe positioning and installation devices generally only secure the portion of the pipe extending from the wall, lacking proper positioning at the right-angle bend. This lack of fixation at the right-angle bend makes the pipe prone to swaying in windy weather, and over time, can damage or break the bend, affecting its normal operation.
[0004] Therefore, it is necessary to improve the existing technology to solve the above-mentioned technical problems. Utility Model Content
[0005] The purpose of this utility model is to provide a smoke exhaust pipe positioning device. By rotating the three pairs of semi-circular clamps on the three rotating hinges, two adjacent locking blocks can be fixed by the locking screws, thereby fixing the two adjacent semi-circular clamps on the left and right sides. This achieves the positioning and installation of the right-angle bend of the smoke exhaust pipe, and strengthens the positioning and fixing of the right-angle bend of the smoke exhaust pipe. This solves the problem that existing smoke exhaust pipe positioning and installation devices lack positioning and installation capabilities for the right-angle bend of the smoke exhaust pipe.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0007] This utility model is a smoke exhaust pipe positioning device, including a mounting plate. Connecting blocks are welded to the upper end and the front end of the outer wall of the mounting plate. Rotating hinges are fixedly installed at the ends of the two connecting blocks away from the mounting plate. Semi-circular clamps are fixedly connected to both ends of the rotating hinges. A connecting plate is welded to the front end of the outer wall of the mounting plate. Three rotating hinges are rotatably connected to the front end of the outer wall of the connecting plate through a connecting assembly. Semi-circular clamps are fixedly connected to both ends of each rotating hinge.
[0008] Furthermore, the mounting plate has symmetrically provided mounting threaded holes on the left and right sides of its outer wall.
[0009] Furthermore, a locking block is integrally formed at the end of the semi-circular clamp away from the rotating hinge, and locking screws are threadedly connected to two adjacent locking blocks.
[0010] Furthermore, the connecting assembly includes a connecting shaft fixedly installed to the front end of the outer wall of the connecting plate, a connecting sleeve 1 rotatably connected to the middle of the side wall of the connecting shaft, a connecting frame 1 fixedly installed on one side wall of the connecting sleeve, a connecting sleeve 2 symmetrically rotatably connected to the side wall of the connecting shaft and located on the left and right sides of the connecting sleeve 1, a connecting frame 2 fixedly installed on the side wall of the connecting sleeve 2, and the front ends of the outer walls of both the connecting frame 2 and the connecting frame 1 are fixedly connected to the rotating hinge 2.
[0011] Furthermore, the second connecting frame is L-shaped, and the installation positions of the two second connecting frames are symmetrical about the first connecting frame.
[0012] Furthermore, a locking block is integrally formed at the end of the semi-circular clamp two away from the rotating hinge two, and locking screws are threadedly connected to two adjacent locking blocks two.
[0013] Furthermore, the inner wall radii of the first semi-circular clamp and the second semi-circular clamp are the same.
[0014] This utility model has the following beneficial effects:
[0015] 1. This utility model uses three pairs of semi-circular clamps on three rotating hinges to fix two adjacent locking blocks by tightening screws, thereby fixing two adjacent semi-circular clamps on the left and right sides. This achieves positioning and installation at the right-angle bend of the exhaust pipe, strengthens the positioning and fixing of the right-angle bend of the exhaust pipe, and improves the service life of the exhaust pipe.
[0016] 2. When in use, the connecting frame one and connecting frame two can be rotated, thereby enabling the position adjustment of the three pairs of semi-circular clamps two, which facilitates the fixing of different positions at the right-angle bend of the exhaust pipe, improving the practicality of the device during installation.

Connecting blocks 200 are welded to both the upper end and the front end of the outer wall of the mounting plate 100. Rotating hinges 210 are fixedly installed at the ends of the two connecting blocks 200 away from the mounting plate 100. Semi-circular clamps 220 are fixedly connected to both ends of the rotating hinges 210. A connecting plate 300 is welded to the front end of the outer wall of the mounting plate 100. Three rotating hinges 500 are rotatably connected to the front end of the outer wall of the connecting plate 300 via a connecting assembly 400. Semi-circular clamps 510 are fixedly connected to both ends of each rotating hinge 500. The mounting plate 100 is used to install and fix the device to the exterior of the kitchen. On wall 1, the upper and lower ends of the exhaust pipe 2 are positioned and fixed by two pairs of semi-circular clamps 220 on two rotating hinges 210, and the right-angle bend of the exhaust pipe 2 is fixed by three pairs of semi-circular clamps 510 on three rotating hinges 500. A locking block 230 is integrally formed at the end of the semi-circular clamp 220 away from the rotating hinge 210. Locking screws 240 are threaded onto two adjacent locking blocks 230, which fix the two adjacent locking blocks 230, thus fixing the two adjacent semi-circular clamps 220 together. (Connecting component 4) The 00 includes a connecting shaft 410 fixedly installed on the front end of the outer wall of the connecting plate 300. A connecting sleeve 420 is rotatably connected to the middle of the side wall of the connecting shaft 410. A connecting frame 430 is fixedly installed on the side wall of the connecting sleeve 420. A connecting sleeve 440 is symmetrically rotatably connected to the side wall of the connecting shaft 410 on the left and right sides of the connecting sleeve 420. A connecting frame 450 is fixedly installed on the side wall of the connecting sleeve 440. The front ends of the outer walls of the connecting frame 450 and the connecting frame 430 are fixedly connected to the rotating hinge 500. By rotating the connecting sleeves 420 and 440, the connecting frame 430 and the connecting frame 450 can be rotated, thereby enabling the rotation of three pairs of... The semi-circular clamp 2 510 is positioned for easy fixation at different locations of the right-angle bend in the exhaust pipe 2. The connecting bracket 2 450 is L-shaped, and the installation positions of the two connecting brackets 2 450 are symmetrical about the connecting bracket 1 430, which facilitates the rotation and adjustment of the two connecting brackets 2 450. The end of the semi-circular clamp 2 510 away from the rotating hinge 2 500 has an integrally formed locking block 2 520. The two adjacent locking blocks 2 520 are threaded with locking screws 2 530.
