Description

Technical Field

[0001] This utility model relates to the field of pipeline installation technology, and more specifically, to a hanger for fixing square tubes to I-beams. Background Technology

[0002] Pipeline installation is a crucial part of building construction. Pipelines are used for transporting domestic water and for building ventilation, among other things. Larger diameter pipes require custom-made brackets to secure them to the interior walls or ceilings of the building to prevent them from falling after installation.

[0003] Some buildings have steel frame structures installed indoors during construction. These are typically composed of I-beams. The vertical supports of the steel frame are located on the interior side walls, while the horizontal supports are located on the interior ceiling. The I-beam frame serves two purposes: load-bearing and facilitating the installation of related equipment. When it is necessary to fix pipes to the I-beams, such as common ventilation square pipes, a fixing bracket is required during installation.

[0004] Some existing mounting brackets for fixing large-sized ventilation square tubes have the following disadvantages: firstly, the mounting brackets are not convenient for quick connection and fixing with I-beams; secondly, the installation speed of ventilation square tubes on the mounting brackets is relatively slow.

[0005] Therefore, a hanger for fixing square tubes to I-beams is proposed. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a hanger for fixing square tubes to I-beams.

[0007] The objective of this utility model is achieved through the following technical solution:

[0008] A hanger for fixing a square tube to an I-beam, the I-beam being installed on a side wall or ceiling of a building; the hanger includes a horizontal bar and two vertical bars disposed at both ends of the horizontal bar, the horizontal bar being detachably connected to the I-beam via a connecting mechanism; the ends of the two vertical bars away from the horizontal bar are detachably connected via telescopic rods.

[0009] Furthermore, in this utility model, the telescopic rod includes a rod body and telescopic units disposed at both ends of the rod body. Each of the two vertical rods is provided with a toothed ring adapted to the telescopic unit at the end away from the horizontal rod. The two telescopic units are detachably connected to the two toothed rings respectively.

[0010] Furthermore, in this utility model, any of the above-mentioned telescopic units includes a limiting sleeve connected to the above-mentioned rod body, a spring sleeved on the above-mentioned rod body, a sleeve slidably disposed at the end of the above-mentioned rod body, and a gear disposed on the above-mentioned sleeve; one end of the above-mentioned spring is connected to the above-mentioned sleeve, and the other end abuts against the above-mentioned limiting sleeve; the above-mentioned gear is adapted to the above-mentioned gear ring, and the diameter of the tip circle of the above-mentioned gear is equal to the diameter of the root circle of the above-mentioned gear ring.

[0011] Furthermore, in this utility model, the aforementioned limiting sleeve is threadedly connected to the aforementioned rod body.

[0012] Furthermore, in this utility model, the connecting mechanism includes a screw connected to the crossbar and a fixing clamp disposed at one end of the screw, wherein the fixing clamp is detachably connected to the I-beam.

[0013] The beneficial effects of this utility model are:

[0014] This utility model provides a hanger for fixing square tubes to I-beams. The hanger can be quickly installed on the I-beams through a connecting mechanism.

[0018] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Please see Figure 1 and Figure 2 This utility model provides a technical solution:

[0020] A hanger for fixing a square tube to an I-beam, wherein the I-beam 201 is installed on a side wall or ceiling 301 of a building; the hanger includes a horizontal bar 401 and two vertical bars 402 installed at both ends of the horizontal bar 401, the ends of the two vertical bars 402 away from the horizontal bar 401 being detachably connected by a telescopic rod 403. Thus, when the square tube 101 is placed between the two vertical bars 402, the telescopic rod 403 is connected to the two vertical bars 402, enabling rapid installation.

[0021] Reference Figure 1 The crossbar 401 is detachably connected to the I-beam 201 via a connecting mechanism. Specifically, the connecting mechanism includes a screw 501 connected to the crossbar 401 and a fixing clip 502 installed at one end of the screw 501. The fixing clip 502 is detachably connected to the I-beam 201. Both the crossbar 401 and the fixing clip 502 can be connected to the screw 501 by bolts. The structure of the fixing clip 502 is adapted to the structure of the I-beam 201. After the fixing clip 502 is installed on the I-beam 201, it is fixed to the I-beam 201 by screws.

[0022] Specifically, in this embodiment, the telescopic rod 403 includes a rod body 4031 and telescopic units installed at both ends of the rod body 4031. Each of the two vertical rods 402, at the end furthest from the horizontal rod 401, is equipped with a toothed ring 404 adapted to the telescopic unit. The two telescopic units are detachably connected to the two toothed rings 404 respectively. Each telescopic unit includes a limiting sleeve 4032 connected to the rod body 4031, a spring 4033 sleeved on the rod body 4031, a sleeve 4034 slidably installed at the end of the rod body 4031, and a gear 4035 installed on the sleeve 4034. One end of the spring 4033 is connected to the sleeve 4034, and the other end abuts against the limiting sleeve 4032. The gear 4035 is adapted to the toothed ring 404. After the connecting mechanism is fixed to the I-beam 201, the square tube 101 is placed between the two vertical rods 402. Then, the two sleeves 4034 are pressed down, causing the two gears 4035 to move towards the two limiting sleeves 4032. Next, the two gears 4035 are aligned with the two gear rings 404, and the two sleeves 4034 are released. The installation is complete once the two gears 4035 are engaged with the two gear rings 404. Under the elastic force of the two springs 4033, the two gears 4035 remain engaged with the two gear rings 404, preventing them from disengaging.

[0023] To limit the radial displacement of gear 4035 within the gear ring 404 and improve the stability of this connection, during manufacturing, the diameter of the addendum circle of gear 4035 is made equal to the diameter of the root circle of gear ring 404 while ensuring proper meshing of gear 4035 and gear ring 404. This ensures that there is no gap between gear 4035 and gear ring 404 in the radial direction after meshing, thus preventing radial displacement of gear 4035 within gear ring 404.

[0024] After the telescopic rod 403 is connected to the two vertical rods 402, the two gears 4035 remain engaged with the two gear rings 404 under the elastic force of the two springs 4033, thus preventing the two gears 4035 from disengaging from the two gear rings 404. The elastic force of the springs 4033 may decrease after prolonged use. To address this issue, a limiting sleeve 4032 is threadedly connected to the rod body 4031. Figure 1 From the perspective of the viewpoint, when it is necessary to adjust the elastic force of the spring 4033, the left limiting sleeve 4032 can be moved to the left by a certain distance, and the right limiting sleeve 4032 can be moved to the right by a certain distance, thus solving the above problem.

[0025] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
