Description

Adjustable ventilation pipe bracket

Technical Field

The utility model relates to the technical field of ventilation pipe brackets, in particular to an adjustable ventilation pipe bracket.

Background Art

Ventilation ducts are piping systems used for air delivery and distribution. Ventilation ducts are usually used inside buildings. When working, ventilation ducts can allow air inside the building to circulate, thereby keeping the air inside the building fresh. Ventilation ducts are generally fixed to the building through ventilation duct brackets.

In the prior art, there is a ventilation duct bracket with adjustable spacing, such as the announcement number CN214662472U, which includes: a ventilation duct, an adjustment plate installed on the outer wall of the ventilation duct, a support rod connected to one side of the adjustment plate, a first cross plate arranged at the bottom end of the support rod, a first slot is provided inside the first cross plate, a first clamping block runs through the inside of the first slot, a first threaded groove is provided inside the first fixing block, a threaded rod runs through the inside of the first threaded groove, a second clamping block is provided on the outer wall of the threaded rod, and a turntable is installed on the end of the threaded rod; when working, the mutual cooperation of the second slot, roller, threaded rod and other parts solves the problem that the existing ventilation duct bracket cannot adjust the distance between the brackets and can only fix ventilation ducts of the same size, which not only increases the cost of installing the ventilation duct equipment, but also reduces the efficiency of installation.

The above solution can be adapted to the installation of ventilation pipes of different diameters, and when it is installed and used, the pad usually needs to be directly fixed to the building with bolts or other structures. However, since the ventilation pipe will vibrate under the influence of airflow when it is working, the vibration of the ventilation pipe can be directly transmitted to the building through the ventilation pipe bracket when the ventilation pipe is working. When the vibration energy transmitted from the ventilation pipe to the building is large, the wall where the ventilation pipe bracket and the building are connected is prone to cracking.

Utility Model Content

The utility model aims to provide an adjustable ventilation pipe bracket, which can prevent the wall of a building from cracking due to the vibration of the ventilation pipe.

To achieve the above-mentioned purpose, an adjustable ventilation pipe bracket is provided, which includes: a bracket frame, support rods are obliquely arranged on both sides of the bracket frame, and mounting seats are rotatably arranged at both ends of the support rod, the mounting seat at one end of the support rod is slidably connected to the bracket frame, a fixing plate is arranged at intervals above the bracket frame, and the mounting seat at the other end of the support rod is connected to the fixing plate; a shock-absorbing assembly, the shock-absorbing assembly is located at the bottom of the fixing plate, and the shock-absorbing assembly includes a shock-absorbing frame, a connecting rod and a spring, the shock-absorbing frame is connected to the fixing plate and arranged at intervals with the bracket frame, and a plurality of connecting rods are provided and arranged in sequence, each connecting rod is slidably penetrated into the shock-absorbing frame, a protrusion is provided on the top of the connecting rod, the protrusion is located in the shock-absorbing frame, the bottom of the connecting rod is fixedly connected to the top of the bracket frame, the spring is sleeved on the connecting rod and is located between the bracket frame and the shock-absorbing frame; an adjusting assembly, the adjusting assembly is located in the bracket frame.

When the ventilation pipe is vibrated by the airflow, the bracket frame moves toward the fixing plate, the connecting rod moves upward, and the spring is compressed. When the vibration disappears or decreases, the bracket frame moves downward due to its own gravity. At this time, the protrusion is located at the bottom of the shock-absorbing frame, and the spring returns to its natural state. During this process, both ends of the support rod rotate along the corresponding mounting seats.

By setting a spring, when the support frame vibrates, the spring is compressed, and the spring absorbs vibration during the compression process, thereby reducing the vibration energy transmitted to the building body, and further avoiding cracks in the wall of the building body; by rotatably setting a mounting seat at both ends of the support rod, when the support frame vibrates, the support rod can rotate along the corresponding mounting seat, thereby avoiding the vibration of the support frame from being transmitted to the building body through the support rod and the fixed plate.

According to the adjustable ventilation pipe bracket, a plurality of reinforcing blocks are arranged in the shock absorbing frame, the reinforcing blocks and the connecting rods are arranged alternately, one end of the reinforcing block is connected to the shock absorbing frame, and the other end of the reinforcing block is connected to the fixing plate.
