Description

Technical Field

[0001] This utility model relates to the field of grating panels, and in particular to an adjustable support frame for steel grating panels. Background Technology

[0002] Steel grating, also known as steel grid, is a steel product made by arranging flat steel bars at specific intervals and crossbars, and welding them together to form a grid with square openings. It is mainly used for trench covers, steel structure platform panels, and stair treads. The crossbars are typically made of twisted square steel. Steel grating is generally made of carbon steel with a hot-dip galvanized finish to prevent oxidation. It can also be made of stainless steel. Steel grating offers ventilation, light transmission, heat dissipation, slip resistance, and explosion-proof properties.

[0003] In existing adjustable support frames for steel grating, the length of some grating panels is fixed during use. However, in actual use, due to installation errors or subsequent settlement, it is often necessary to adjust the length of the steel grating panels. Therefore, we propose an adjustable support frame for steel grating to solve this problem. Utility Model Content

[0004] The purpose of this utility model is to provide an adjustable support frame for steel grating to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An adjustable support frame for steel grating includes: an outer grating plate; an inner grating plate slidably connected to the inner side of the outer grating plate; a first frame fixedly connected to one side of both the outer and inner grating plates; a second frame slidably connected to the inner sides of both first frames; two first blocks fixedly connected to one side of the outer grating plate; grooves formed on the inner sides of both first blocks; cylinders slidably connected to the inner sides of both grooves; a second block fixedly connected to one side of both cylinders; multiple insertion holes adapted to the second blocks formed on the inner side of the inner grating plate; two second blocks movably inserted into the inner sides of their corresponding insertion holes; a third block fixedly connected to one side of each cylinder; two third blocks slidably connected to the inner sides of their corresponding first blocks; a round rod rotatably connected to the inner sides of each third block; and a fourth block rotatably connected to the outer sides of each round rod, with one side of each fourth block movably abutting against one side of its corresponding first block.

[0007] Preferably, one side of each of the two blocks No. 1 and No. 4 is provided with rounded corners, and one side of each of the two grooves is fixedly connected with a spring. The other end of each of the two springs is fixedly connected to one side of the corresponding block No. 2, and one side of each of the two blocks No. 4 is fixedly connected with multiple protrusions.

[0008] Preferably, each of the two second frames is fixedly connected to a housing on one side, and a round rod and a screw are rotatably connected to the inner side of each of the two housings. A worm is fixedly connected to the outer side of each of the two round rods, and a worm wheel is meshed with the outer side of each of the two worms. The inner side of each of the two worm wheels is fixedly connected to the outer side of the corresponding screw, and a connecting shell is threaded to the outer side of each of the two screws. One side of each of the two connecting shells is fixedly connected to the other side of the corresponding first frame.

[0009] Preferably, both of the first frames are threaded with bolts on their inner sides, and both of the second frames are provided with multiple threaded holes that are compatible with the bolt threads on their inner sides. The outer sides of both bolts are threaded into the corresponding threaded holes.

[0010] Preferably, a handwheel is fixedly connected to one side of each of the two round rods.

[0011] Preferably, both of the second frames are fixedly connected to a base at their bottom, and both sides of the outer grid plate are fixedly connected to a protective pad.

[0012] In this utility model, an adjustable support frame for steel grating is provided. By installing the device in a suitable position, when the length of the outer grating needs to be adjusted, the user can directly move block number four to rotate it 90 degrees. Then, the user can pull out the outer or inner grating to adjust the length. After that, the user can move block number four in the opposite direction to rotate it 90 degrees again. During this process, as block number four rotates, the cylindrical rod begins to rotate, and then block number three begins to move horizontally. At this time, the spring is no longer compressed by the cylinder, and then the cylinder drives block number two into the inner side of the inner grating.

[0013] In this utility model, an adjustable support frame for steel grating is provided. The user can adjust the length of the device. When the user needs to adjust the height of the device, he can directly turn the handwheel, which makes the round rod start to rotate. Then the worm gear drives the worm wheel to rotate, and then the screw starts to rotate. This makes the connecting shell drive the first frame to move vertically. After the adjustment is completed, the bolt is installed inside the corresponding threaded hole. At this time, the height adjustment of the device is completed, which makes it convenient for the user to use. The first frame, the second frame, the outer grating and the inner grating are all made of high-strength materials.

[0014] The structure of this utility model is reasonably designed. Through the cooperation between the first block, the protective ridge, the second block, and the third block, the user can adjust the horizontal length of the grating plate when needed, which facilitates daily use.
