Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of building engineering, and more particularly to a level telescopic support. BACKGROUND

[0002] In many fields such as building construction, decoration, equipment installation and machining, accurate horizontal measurement is the key link to ensure the quality of the project and the normal operation of the equipment, and the stable and reliable support frame of the level plays a decisive role in realizing accurate horizontal measurement. However, the traditional level support has exposed many problems in practical application, which greatly limits the efficiency and accuracy of horizontal measurement work.

[0003] From the height adjustment capability, the height adjustment range of the traditional level support is extremely limited. Most of the traditional supports have fixed height and cannot adapt to the diversified needs of different scenes; some have adjustment function, but can only make simple several-stage adjustment, which is difficult to meet the complex and changeable construction environment. For example, in the indoor decoration project of high-rise building, when the ceiling or wall at a higher position needs to be measured horizontally, the staff has to use ladders and other auxiliary tools because the traditional support cannot reach the corresponding height, which not only increases the risk of operation, but also seriously affects the measurement efficiency. In some work that needs to measure the ground at a lower position or a narrow space, the traditional support cannot be flexibly lowered in height, which makes the measurement work difficult to carry out smoothly and the accuracy difficult to guarantee.

[0004] In terms of stability, the fixing method of the traditional support has defects. Although the common bolt and nut connection structure can realize the fixation of the support to a certain extent, the operation process is complicated, and a lot of time and manpower are needed to tighten and loosen the operation every time the height is adjusted. More seriously, this connection method is prone to loosening during long-term use due to external factors such as vibration and collision in the construction site. Once the support is loosened, the level will tilt, resulting in deviation of the measurement data and quality hidden danger for subsequent construction and installation work.

[0005] From the perspective of portability and space occupation, the design of the traditional level support also has obvious shortcomings. Most of the traditional supports are large in size and fixed in structure, and cannot be telescopic or foldable. Some triangular supports can be stored, but during the frequent transfer in the construction site, such supports are difficult to carry and need to occupy a large transportation space, increasing the transportation cost and management difficulty. At the same time, when stored in the warehouse, due to its large size, it also occupies a large amount of valuable storage space, which is not conducive to the rational use of resources. Especially in some small construction sites with limited space or projects that need to change the work site frequently, the inconvenience of the traditional support is particularly prominent.

[0006] In view of these problems existing in the conventional level support, it is imminent to develop a new type of level telescopic support which is flexible in height adjustment, strong in stability, and convenient to carry and store. The level telescopic support is designed to solve these industry pain points and aims to provide a more efficient and reliable support solution for level measurement work in various fields.

[0031] Specific use method:

[0032] When the level telescopic support is used in a house, first, the support is placed near the position to be measured, and it is ensured that the grounding base is in good contact with the ground.

[0033] According to the height requirement of the house, the third plate buckle type locker, the second plate buckle type locker and the first plate buckle type locker are sequentially pulled, the corresponding supporting rods are unlocked, then the supporting rods are stretched or contracted, after being adjusted to a suitable height, the plate buckle type lockers are pulled again to lock and fix the supporting rods.

[0034] In the process of adjusting the height of the support, if it is necessary to increase the stability of the support, the foot can be used to press the pedal pressing plate to make the ground base more firmly adhere to the ground, and the reset spring is retracted. When approaching the top, the foot is released, and under the action of the restoring force of the reset spring, the entire support rod is stably fixed between the ceiling and the ground of the room.

[0035] The level is installed at a suitable position of the support for horizontal measurement operation.

[0036] After the measurement is completed, the level is disassembled from the support, and then the plate buckle type lockers are unlocked from the lower part in sequence, and each support rod is retracted in sequence until all the support rods are retracted into the support rod one, and then the support is stored for next use.
