In order to solve the problem that the current trowel function of plastering usefulness is single, be difficult to deal with scenes such as various reentrant corner external corner, the utility model provides a novel plastering tool, as shown in fig. 1 and fig. 2.
A novel plastering tool comprises left and right scraping plates 1 with hinged edges, a handle 2 is arranged above a hinged shaft 5a of the two scraping plates 1, the two scraping plates 1 are respectively connected with the handle 2 through supporting legs 3, one end of each supporting leg 3 is hinged to the corresponding scraping plate 1, and the other end of each supporting leg is hinged to the corresponding handle 2; the two scrapers 1 and the support legs 3 on the scrapers 1 are combined together to form a four-bar mechanism which is symmetrical left and right;
The original single scraper blade 1 is changed into two scraper blades 1 which are hinged with each other, and the included angle of the two scraper blades 1 is controlled, so that the plastering tool can adapt to various operation scenes such as planes, internal corners, external corners and the like. Specifically, the legs 3 are hinged on the scrapers 1, and then the legs 3 of the two scrapers 1 are respectively hinged to the handle 2, so that the two legs 3 and the two scrapers 1 form a four-bar mechanism in one plane, that is, the hinge shafts 5a of all the hinged connections are parallel to each other, that is, the hinge shafts 5a at the two ends of the legs 3 are parallel to the hinge shaft 5a between the two scrapers 1. And the four-bar mechanism is symmetrical on the left and right sides, that is, the length of the leg 3 connected with different scrapers 1 is the same, and the hinged position of the leg 3 and the scrapers 1 is the same with the vertical distance of the hinged shaft 5a between the two scrapers 1.
Form can not fix in a definite position behind the four-bar linkage, so the utility model discloses still have push rod 4, 4 tip of push rod and two scraper blade 1's articulated shaft 5a fixed connection, the middle part of push rod 4 runs through handle 2 and slidable mounting is on handle 2, like this when sliding push rod 4, alright adjust two scraper blade 1's contained angle, after adjusting suitable angle, rethread locking mechanism fixes push rod 4, alright with two scraper blade 1 lockings on certain angle, handheld handle 2 can be to the wall of different angles or cloudy, the operation is plastered to the external corner.
As shown in fig. 2, the two scrapers 1 are arranged in bilateral symmetry, the handle 2 is arranged right above the hinge shafts 5a of the two scrapers 1, then the support legs 3 are rotatably connected to the handle 2, the ends of the support legs 3 are respectively connected with the upper surfaces of the two scrapers 1, and the distance from the joints of the support legs 3 and the scrapers 1 to the hinge shafts 5a needs to be less than the length of the two support legs 3. The push rod 4 is fixedly connected with the hinging shaft 5a, and the push rod 4 vertically penetrates the grip 2 upwards perpendicular to the hinging shaft 5a and can slide up and down on the grip 2 along the axis of the push rod 4. Specifically, the scraper 1 is a flat plate material, which is the same as the original trowel, and the material of the plate material can be stainless steel or plastic. Landing leg 3 can adopt the plastics material also can make with the steel pipe, can set up a plurality of landing legs 3 simultaneously on the same scraper blade 1, as shown in fig. 2, arbitrary scraper blade 1 is connected with handle 2 through two landing legs 3 around respectively, and two landing legs 3 are parallel to each other, and two landing legs 3 coincide with this scraper blade 1's pivot moreover.
Preferably, the handle 2 is parallel to the hinging axis 5a of the two scrapers 1, so that on one hand, the handle 2 is parallel to the hinging axis 5a, and when in use, the handle can push the plasterer to move forwards and backwards conveniently and smoothly. And the legs 3 can be turned directly around the grip 2. But preferably, the fixed mounting seats 2a are arranged at both ends of the handle 2, and the supporting legs 3 are hinged with the mounting seats 2a, so that the hinged shafts 5a can be conveniently arranged and are firmer.
The length of the support leg 3 is adjustable; the supporting legs 3 comprise supporting rods 3a at two ends and a sleeve 3b in the middle, threads with opposite screwing directions at two ends are arranged on the inner walls at two ends of the sleeve 3b, and the end parts of the two supporting rods 3a are respectively sleeved at two ends of the sleeve 3b and are in threaded connection with the sleeve 3 b. By rotating the sleeve 3b, the legs 3 at both ends move in opposite directions, and the length of the entire leg 3 is lengthened or shortened.
Since the push rod 4 needs to slide on the grip 2 and needs to be locked, preferably, as shown in fig. 1, the push rod 4 is installed in a threaded manner with the grip 2, the push rod 4 is provided with threads in the middle, the grip 2 is provided with a threaded hole matched with the push rod 4, and the push rod 4 is installed in the threaded hole; the end part of the push rod 4 far away from the scraper 1 is provided with a hand wheel 4a which is convenient for rotating the push rod 4. The push rod 4 can move up and down on the grip 2 by rotating the hand wheel 4a, and the threads have self-locking capacity without rotating the hand wheel 4a, so that the push rod 4 can not automatically slide up and down.
Similarly, a polish rod can be used as the push rod 4, then a set screw is installed on the grip 2, and the tail part of the set screw pushes the push rod 4 tightly to lock the sliding of the push rod 4. When the push rod 4 needs to be adjusted, a set screw is loosened, adjusted to a proper position and then tightened again, and the set screw is preferably a manual adjusting screw which can be rotated by bare hands.
As shown in fig. 2, when plastering an external corner, the hinge shaft 5a needs to be adjusted upward in order to avoid collision of the leg 3 with the screed 1. The leg 3 is connected to the blade 1 through the leg base 6, the leg base 6 is fixed to the surface of the blade 1, the leg 3 is hinge-connected to the leg base 6, and the rotation axes of the leg 3 and the leg base 6 are parallel to the blade 1 and located outside the surface of the blade 1. While the leg rest 6 also provides a secure mounting position for the legs 3 on the blade 1.
Scraper blade 1 is the dull and stereotyped of rectangle, the edge that scraper blade 1 is connected with another scraper blade 1 is the wedge, and the one side that scraper blade 1 connects landing leg 3 forms wedge-shaped closed angle at seam department downward sloping, and the closed angle department of two scraper blades 1 is through hinge 5 articulated connection. The working face that scraper blade 1 and landing leg 3 carried on the back mutually caves in seam department and forms the recess, and hinge 5 of connecting two scraper blades 1 installs in the recess, keeps the working face level and smooth.
If the scraper 1 is made of thin stainless steel, a wedge-shaped sharp corner is not needed to be arranged, and the scraper can be directly connected with the hinge 5. Hinge 5 is provided on the upper surface of blade 1.
The above-mentioned embodiments are only described for the preferred embodiments of the present invention, and are not limited to the scope of the present invention, and the ordinary skilled person in the art can modify and improve the technical solution of the present invention without departing from the design spirit of the present invention, including using the present invention in old house decoration, and all should fall into the protection scope defined by the claims of the present invention.
