Detailed Description

The present invention will be described in further detail with reference to the accompanying fig. 1-4.

The embodiment of the utility model discloses arc angle adjustable trowel.

Referring to fig. 1, 2, 3 and 4, the trowel with adjustable arc angle comprises a trowel plate 1 and a bending driving device 2, wherein the trowel plate 1 is made of an elastic thin steel plate; the bending drive means 2 is used to apply a bending force to the spatula 1 to bend the spatula. The deformation of the trowelling plate 1 is realized by adjusting the bending driving device 2, the purpose of changing the angle is achieved, the trowelling plate is further suitable for arc-shaped curve construction of various shapes, the contradiction that various tools need to be frequently replaced is well solved, the field construction is facilitated, and the construction cost is reduced.

The front surface of the plastering plate 1 is used for plastering. The trowel 1 can be made of elastic aluminum alloy plate, elastic thin steel plate, elastic plastic plate and elastic iron sheet, and in this embodiment, the trowel 1 is made of elastic thin steel plate. The elastic thin steel plate is bendable, good in plasticity and not easy to deform, and can realize larger bending deformation, so that the purpose of adjusting the angle in use is met.

The bending driving device 2 comprises a supporting seat 21 and an adjusting part 22, the supporting seat 21 comprises a connecting seat 212 and two hinged seats 211, in the embodiment, the connecting seat 212 comprises two vertical parts and a horizontal part, and the two vertical parts are integrally formed at two ends of the horizontal part, so that the cross section of the connecting seat 212 is of a 20866; "type. Two vertical portions of connecting seat 212 are articulated with two articulated seats 211 respectively, and two articulated seats 211 are all sliding fit setting at the back of board 1. In this embodiment, the back integrated into one piece of board 1 has fixing base 11, has seted up the sliding tray on the fixing base 11, and articulated seat 211 keeps away from the one end rotation of connecting seat 212 and installs the round bar, and the round bar can rotate relatively also can slide in the sliding tray. The trowel plate 1 and the hinged seat 211 can slide freely, and the hinged seat 211 and the connecting seat 212 are hinged with each other, so that the trowel plate 1 can be bent and deformed freely under the condition that the connecting seat 212 is not deformed.

The back of the connecting base 212 is fixedly provided with a handle 3, and the back of the connecting base 212 is the horizontal part of the connecting base 212 and is far away from one side of the troweling board 1. The staff removes the trowel through grab handle 3, makes things convenient for the staff to use.

The adjusting part 22 adjusts the bending degree of the trowel 1 by adjusting the position in the supporting seat 21 in a sliding way. In the embodiment, the adjusting portion 22 includes a screw 221 and a nut 222, a horizontal portion of the connecting seat 212 is provided with a waist-shaped hole for the screw 221 to slide, and the waist-shaped hole is provided in the horizontal portion of the connecting seat 212 along a horizontal direction. In this embodiment, two screws 221 are installed at intervals along the length direction of the trowel. One end of the screw rod 221 is hinged with the back of the floating plate 1, the other end of the screw rod is connected in the kidney-shaped hole in a sliding mode, and the nut 222 is connected to the screw rod 221 in a threaded mode and limits the screw rod 221 to slide in the kidney-shaped hole in a reciprocating mode.

In this embodiment, two nuts 222 are mounted on one screw 221, and the two nuts 222 are respectively disposed on two sides of the supporting seat 21 and limit the screw 221 to slide back and forth in the kidney-shaped hole. Two nuts 222 are respectively in threaded connection with the screw rod 221, so that the worker can conveniently adjust the concave and convex bending of the trowel plate 1, and the adjustment accuracy is improved.

When the trowel 1 is recessed, a worker firstly rotates the nut 222 far away from the trowel in the direction far away from the trowel, then rotates the nut 222 close to the trowel in the direction far away from the trowel through a tool such as a wrench, and the like, so that the trowel 1 is recessed, and after the trowel 1 is bent to a specified degree, the nut 222 far away from the trowel is screwed on the horizontal part of the connecting seat 212; in the same way, the convex working process of the plastering plate 1 can be obtained. The position of the screw rod 221 in the waist-shaped hole is changed by rotating the screw cap 222, so that the bending degree of the floating plate 1 is adjusted, and the floating plate 1 is convenient and accurate to bend.

Through using screw rod 221, one end articulates on trowelling plate 1, and one end uses two nuts 222 to be connected to the tow sides of supporting seat 21, through adjusting the nut 222 of tow sides, can make the length of screw rod 221 change between supporting seat 21 and the trowelling plate 1, has very big flexibility. The purpose of adjusting the angle of the trowelling plate 1 is achieved, so that the trowelling plate can easily meet the requirements of various arc shapes of construction projects, and has higher attaching degree and applicability.

In other embodiments, the adjusting portion 22 may further include a pneumatic support rod or a manual telescopic rod, the manual telescopic rod includes an inner rod and an outer rod, the inner rod is hinged to the trowel plate 1, the outer rod is hinged to the supporting seat 21, the inner rod is slidably disposed in the outer rod, a knob is disposed on the outer rod, the knob penetrates through the supporting seat 21 and the outer rod and is in threaded connection with the inner rod, and the worker rotates the knob to enable the inner rod to slide relative to the outer rod.

The angle adjustability that this trowel had can adapt to the requirement of plastering of wider scope angle, to the angle of plastering bigger tolerance, more economical and applicable, convenient nimble construction more, and the labour demand reduces by a wide margin simultaneously, has improved the work efficiency of plastering greatly, has practiced thrift the cost.

Adopt the utility model discloses a trowel has increased the work efficiency that sloping roof and gable ridge junction arc reentrant corner of sloping roof plastered, has shortened the time of concrete operation of making level for the construction progress, simultaneously, greatly reduced the working strength who plasters, reduced labour's input, reduced the cost input of plastering.

Above is the preferred embodiment of the utility model, not limit according to this the utility model discloses a protection scope, the event: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
