[0002] After the indoor thermal insulation self-leveling is poured, the surface of the self-leveling needs to be smoothed to make it smooth and without pits. Usually, small-area self-leveling is done by manually smearing a trowel bar back and forth on the surface of the self-leveling to smooth the surface of the self-leveling. However, the manual smearing operation with a trowel bar limits the range of smoothing. Therefore, construction workers need to frequently walk in the self-leveling to leave footprints, and then smooth out the footprints, which is time-consuming and laborious.

[0023] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in combination with the specific embodiments of the application and with reference to the accompanying drawings.

[0024] like Figure 1-2As shown, a self-leveling trowel device for gypsum-based thermal insulation mortar comprises: a first trowel component 1, a first trowel strip 3 is arranged at the lower part of the first trowel component 1, the length of the first trowel strip 3 is the same as the length of the first trowel component 1, one end of a telescopic rod 11 is connected to the upper part of the first trowel component 1, and the other end of the telescopic rod 11 is connected to a handle 10 through a connecting bolt 12. During use, construction personnel can flexibly adjust the length of the telescopic rod 11, and the two ends of the connecting bolt 12 are respectively threadedly connected to the telescopic rod 11 and the handle 10. The first trowel component 1 is provided with two adjustment slots 7 that are arranged through, and the two adjustment slots 7 are arranged at the same height level on the first trowel component 1. Preferably, the two adjustment slots 7 are arranged at the same height level on the first trowel component 1. The upper and lower grooves are symmetrically distributed, and the adjusting grooves 7 are arranged as arc grooves. The upper and lower groove walls are wavy and symmetrical up and down. Each adjusting groove 7 is equipped with a second smoothing component 2. The second smoothing component 2 includes a movable plate 4. A second smoothing strip 5 is arranged at the lower part of the movable plate 4. The lower end of the second smoothing strip 5 is arranged at the same height as the lower end of the first smoothing strip 3. A movable rod 6 is fixedly connected to the side of the movable plate 4 close to the first smoothing component 1. The movable rod 6 is used to cooperate with the adjusting groove 7. When the construction personnel need to adjust the length of the smoothing part, they can pull the second smoothing component 2 to change the matching position of the second smoothing component 2 and the first smoothing component 1, thereby adjusting the length of the smoothing part to adapt to different smoothing construction work areas.

[0025] like Figure 1-2 and Figure 5-6As shown, the moving rod 6 includes: a limit plate 601, a connecting rod 602, an arc block 603 and a first spring 604. One end of the connecting rod 602 is fixedly connected to the moving plate 4, and the other end passes through the adjustment groove 7 and is fixedly connected to the limit plate 601. The length of the connecting rod 602 is the same as the depth of the adjustment groove 7. The diameter of the limit plate 601 is larger than the maximum width of the adjustment groove 7, so as to prevent the moving rod 6 from falling off from the adjustment groove 7. The upper and lower sides of the connecting rod 602 are slidably connected with an arc block 603. The connecting rod 602 is provided with a cavity for accommodating the arc block 603, and the cavity can completely accommodate the arc block 603. The arc block 6 A plurality of first springs 604 are arranged between 03 and the connecting rod 602, and the first springs 604 are used to push out the arc block 603, and the shape of the arc block 603 is adapted to the shape of the adjusting slot 7. When the two arc blocks 603 are in the ejected state, the two arc blocks 603 fit with the upper and lower arc side walls of the adjusting slot 7, and the cross-sectional shape of the connecting rod 602 is adapted to the shape of the adjusting slot 7. The cross-sectional shape of the connecting rod 602 is a rectangle with two short sides being arcs. The cross-sectional width of the connecting rod 602 is the same as the shortest width of the adjusting slot 7, and the cross-sectional width length of the connecting rod 602 is greater than the length between the two adjacent shortest widths of the adjusting slot 7. When the moving rod 6 does not move in the adjusting groove 7, the upper and lower arc blocks 603 of the moving rod 6 both extend out to cooperate with the upper and lower arc side walls in the adjusting groove 7. When the moving rod 6 moves, the upper and lower arc blocks 603 are squeezed with the upper and lower arc side walls of the adjusting groove 7, and the arc blocks 603 shrink back into the connecting rod 602. The connecting rod 602 moves in the adjusting groove 7 until the moving rod 6 moves to the desired position. The arc blocks 603 extend out under the action of the first spring 604 and continue to cooperate with the arc side walls of the adjusting groove 7. Through the setting of the moving rod 6 and the adjusting groove 7, the construction personnel only need to pull the second smoothing component 2 with appropriate force to change the positional relationship between the second smoothing component 2 and the first smoothing component 1, and the cooperation between the moving rod 6 and the adjusting groove 7 can avoid the second smoothing component 2 and the first smoothing component 1 from moving during the smoothing operation.

[0027] like Figure 3-4As shown, the tension adjustment component 14 includes: a friction plate 1401, a second spring 1402, a baffle 1403 and an adjusting bolt 1404. A mounting hole for installing the friction plate 1401 is opened on the side wall that cooperates with the rotating ring 8. One end of the second spring 1402 is fixedly connected to the side of the friction plate 1401 away from the rotating ring 8, and the other end of the second spring 1402 is fixedly connected to the baffle 1403. A threaded hole is opened on the side wall of the mounting hole away from the rotating ring 8. The threaded hole penetrates the rotating seat 9, and the adjusting bolt 1404 is threadedly connected in the threaded hole. By rotating the adjusting bolt 1404, the construction personnel can change the length of the second spring 1402, thereby changing the pressure between the friction plate 1401 and the rotating ring 8, and thus changing the tightness of the rotating ring 8 on the rotating seat 9. On the one hand, it can prevent the rotating ring 8 and the rotating seat 9 from becoming too loose after a long period of cooperation, making it impossible for the construction personnel to control the posture of the smoothed area through the operating lever; on the other hand, the construction personnel can flexibly adjust the tightness of the rotating ring 8 and the rotating seat 9 through the tension adjustment component 14 to meet their own usage habits.
