Description

Technical Field

[0001] The present application relates to the field of trowel machines, and in particular to a floor trowel machine. Background Art

[0002] The main structure of a floor trowel machine is a trowel rotor driven by a gasoline engine. 2 to 4 trowels are installed on the bottom of the cross in the middle of the rotor. The inclination direction of the trowel is consistent with the rotation direction of the rotor. The gasoline engine drives the V-belt to rotate the trowel rotor. It can be widely used in slurry raising, leveling and polishing of concrete surfaces in high-standard factories, warehouses, parking lots, squares, airports and frame buildings. It is the preferred machine in concrete construction.

[0003] In the prior art, during the placement of a floor trowel, a large area is occupied due to the long connection length between the handrail and the chassis and the difficulty in disassembly of the handrail and the chassis. In addition, the handle length of a general trowel is mostly fixed, and different users have different requirements for the handle length of the trowel. The fixed handle length is not convenient for different users to use.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0005] In order to solve the problem that the handrail is difficult to disassemble and the handle length is difficult to adjust, the present application provides a floor trowel.

[0006] The present application provides a floor trowel machine that adopts the following technical solution:

[0007] A floor trowel comprises a machine body and a connecting rod, wherein a connecting block is fixedly connected to one side of the outer surface of the machine body, a fixed cavity is provided on the inner side of the connecting block, a sliding groove is provided on one side of the outer wall of the connecting block, a second spring is fixedly connected to the inner side of the sliding groove, a mounting rod is elastically slidably connected to the inside of the sliding groove via the second spring, and a pull plate is fixedly connected to one side of the outer wall of the mounting rod.

[0008] Preferably, a mounting block is fixedly connected to one side of the outer wall of the connecting rod, a mounting hole is opened on the outer wall of the mounting block corresponding to the side of the mounting rod, and a fixing block is fixedly connected to one side of the outer wall of the mounting block corresponding to the fixed cavity.

[0009] Preferably, a limiting groove is provided on one inner side of the connecting rod, a first spring is fixedly connected to one inner side of the limiting groove, and a limiting block is elastically slidably connected to the inner side of the limiting groove via the first spring.

[0010] Preferably, a support rod is slidably connected to one side of the outer wall of the connecting rod, and a plurality of limiting holes are formed on the outer wall of the support rod corresponding to one side of the limiting block.

[0011] Preferably, protective covers are fixedly connected to the four corners of the outer surface of the body, and the lower surface of the body is fixedly connected to a bottom ring via a plurality of the protective covers.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] 1. The installation rod is driven to move by pulling the pull plate, and the fixing block is aligned with the fixing cavity, and then the fixing block is inserted into the fixing cavity. The fixing block is installed in the fixing cavity by rotating the connecting rod 90 degrees, and the mounting hole is aligned with the mounting rod, so that the pull plate is loosened, and the elastic potential energy generated by the compression of the second spring pushes the mounting rod into the mounting hole. Compared with the prior art, it is convenient to quickly disassemble and assemble the connecting rod, and reduces the situation where the large floor space is occupied due to the connection between the connecting rod and the body;

[0014] 2. By pressing the limit block into the limit groove, the first spring is squeezed to deform, and the handrail is pulled to move by pressing the limit block. When the limit hole is aligned with the limit block, the elastic potential energy generated by the deformation of the first spring pushes the limit block out of the limit hole, and then the position of the handrail is adjusted, thereby extending the overall connection length of the handrail and the connecting rod. Compared with the prior art, it is easy to adjust the length of the handrail, so as to meet the usage habits of different staff members. BRIEF DESCRIPTION OF THE DRAWINGS
