Description

Technical Field

[0001] This utility model relates to a positioning device, and in particular to a central air conditioning duct installation positioning device. Background Technology

[0002] Central air conditioning is a system that centrally processes air and regulates the indoor environment. It connects a unified main unit with multiple terminal devices to control the temperature, humidity, and air quality of a large space.

[0003] Central air conditioning outdoor units are typically installed on the roof, while terminal units are located in individual rooms. The main unit and terminal units are connected via pipes. In existing office buildings, central air conditioning systems are usually pre-installed, with the air conditioning ducts pre-positioned and secured using hangers. Later tenants, to enhance the aesthetics of the building, often design suspended ceilings. However, during ceiling installation, interference between the hangers and the ceiling frequently occurs. Since the ceiling is already partially installed, drilling expansion bolt holes in the roof again is not only inconvenient but also contaminates the ceiling. The original hangers used for positioning are no longer suitable and must be removed. At this point, the ducts lack proper positioning and securing devices, posing a safety hazard. Therefore, designing an installation device that can utilize the existing hanger expansion bolt holes and secure the air conditioning ducts is clearly essential. Utility Model Content

[0004] The purpose of this utility model is to provide a central air conditioning pipe installation and positioning device to solve the pipe installation problems that exist during the installation of central air conditioning.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A central air conditioning duct installation positioning device, comprising

[0007] Base;

[0008] A turntable, which is rotatably mounted on a base;

[0009] Locking bolt A is screwed onto the turntable and its end extends out of the turntable and abuts against the surface of the base.

[0010] Screw sleeve, connected to the turntable;

[0011] A boom includes a connecting rod A, which extends vertically and has one end screwed into a threaded sleeve. The other end of the connecting rod A is connected to a horizontally extending connecting rod B, and the end of the connecting rod B away from the connecting rod A is connected to a vertically extending connecting rod C.

[0012] The clamp is rotatably connected to the connecting rod C.

[0013] Preferably, the connecting rod C is a telescopic rod.

[0014] Preferably, the base surface facing the turntable is provided with a friction pad, and the end of the locking bolt A abuts against the friction pad.

[0015] Preferably, the turntable is provided with a radially extending slide groove, in which a slider is slidably disposed. The screw sleeve is connected to the slider, and a locking bolt B is screwed onto the slider. The end of the locking bolt B has frictional force and abuts against the bottom of the slide groove.

[0016] Preferably, the turntable is provided with a retaining ring around both ends of the slide groove.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This solution improves the structure of the boom, allowing the position of the bottom end of the boom to be adjusted as the turntable rotates, thus accommodating the problem of deviation between the installation positioning device and the position of the pipeline below.

[0023] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] like Figures 1-3 The central air conditioning duct installation and positioning device shown includes a base 1, which is disc-shaped and has four bolt holes evenly distributed around its edge. Expansion bolts are used to fix the base to the ceiling of the room. A through hole is provided in the center of the base, through which a turntable 2 is rotatably connected.

[0027] like Figure 1 As shown, two locking bolts A3 are symmetrically screwed onto the turntable. When the end of the locking bolt A protrudes and abuts against the surface of the chassis with friction, the turntable and the base can no longer rotate relative to each other.

[0028] Meanwhile, a threaded sleeve 4 is also connected to the turntable, and a lifting rod 5 is fixedly connected to the threaded sleeve. The lower end of the lifting rod is connected to a clamp 6 that can be clamped onto the central air conditioning duct to position and lift the central air conditioning duct.

[0029] It's important to understand that during the installation of central air conditioning ducts, to avoid interference between the hanger 5 and the ceiling, the hanger 5 in this design has an obstacle avoidance function. Specifically, the hanger includes connecting rod A51, connecting rod B52, and connecting rod C53. One end of connecting rod A is threaded and screwed into the threaded sleeve 4 to achieve connection with the threaded sleeve. Connecting rod A extends vertically, and connecting rod B52 is fixedly connected to the end of connecting rod A away from the threaded sleeve. Connecting rod B extends horizontally, perpendicular to connecting rod A, and connecting rod C53 is fixedly connected to the end of connecting rod B away from connecting rod A. Connecting rod C53 is vertically arranged, perpendicular to connecting rod B and parallel to connecting rod A. When there is interference between the hanger and the ceiling (especially a grid-type ceiling), the locking bolts are loosened, allowing the turntable to rotate the hanger relative to the base. This allows the hanger to pass through the ceiling and achieve fixation and positioning with the air conditioning ducts, ensuring the integrity of the ceiling installation.

[0030] It should be noted that in this solution, the connecting rod C53 is a telescopic rod structure that can extend or retract in length to accommodate the connection requirements of air conditioning ducts with various height differences.

[0031] It should be noted that, in this design, to ensure that the locking bolt A does not slip relative to the base when performing the locking function, a friction pad 11 is provided on the base 1. This friction pad is located on the circle drawn with the center of the turntable around the locking bolt A, so as to ensure that the end of the locking bolt A can abut against the friction pad 11 with friction.

[0032] Furthermore, to improve the adjustment range, a groove 21 extending radially along the turntable is provided on the turntable, in which a slider 7 is slidably mounted. In this design, a threaded sleeve is fixedly connected to the slider to move synchronously with it. A locking bolt B8 is also screwed onto the slider 7; the end of the locking bolt B passes through the slider and abuts against the bottom of the groove with friction. Therefore, when the length of the connecting rod B is insufficient, the adjustment radius of the boom can be further increased by adjusting the position of the slider in the groove.

[0033] As a preferred embodiment of the above scheme, in order to prevent the slider from sliding out of the groove, a retaining ring 22 is also provided on the flat circle of the turntable 2. The retaining ring is higher than the bottom of the groove to block the slider that slides to both ends of the groove.

[0034] Working Principle: When interference occurs between the ceiling and the original suspension rods during ceiling installation, the workers remove the original suspension rods and replace them in their original positions using this solution, eliminating the need for additional expansion bolt holes. Next, loosen the locking bolt A3 on turntable 2 to allow turntable 2 to rotate relative to base 1. As the turntable rotates, the suspension rods connected to it via the threaded sleeve 4 also rotate. When the connecting rod A is above the ceiling and the suspension rod C can pass downwards through the ceiling, tighten the locking bolt A until its end abuts against the base. At this point, there will be no relative rotation between the base and the turntable. After the above adjustments are completed, tighten the clamp onto the air conditioning duct. It should be noted that if simply rotating turntable 2 is insufficient to adjust the suspension rods—for example, if the length of connecting rod B is insufficient to allow connecting rod C to avoid the ceiling—the locking bolt B can be loosened to allow the slider to slide a certain distance on the groove, thus compensating for the insufficient length of connecting rod B and moving connecting rod C to a position away from the ceiling.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
