In some embodiments, the C-shaped frame 1 comprises an upper side plate and a lower side plate which are arranged side by side, wherein one guard plate 2 is connected with the upper side plate, the other guard plate is connected with the lower side plate, the upper side plate is provided with a jack 6 for inserting the grinding sheet 5, the jack 6 is in a strip shape and penetrates through the upper side plate, so that the grinding sheet 5 can extend into the C-shaped frame 1 through the insertion holes 6, correspondingly, one side of the lower side plate facing the upper side plate is provided with a clamping groove, for embedding and connecting the grinding sheets 5, and the width of the grinding sheets 5 is larger than the distance between the upper side plate and the lower side plate, when the abrasive disc 5 is installed, the abrasive disc 5 extends into the C-shaped frame 1 from the insertion hole 6 and is clamped in the clamping groove of the lower side plate, so that the abrasive disc 5 is detachably connected with the C-shaped frame 1, when the C-shaped frame 1 is pulled to polish, the grinding sheet 5 is not easy to be stressed and separated, and the connection stability of the grinding sheet 5 is ensured.
It should be noted that, in order to strengthen the steadiness that abrasive disc 5 connects, be provided with the welt in the inboard of curb plate and lower side board, above-mentioned draw-in groove is seted up on the welt, and above-mentioned slot runs through the welt, so, has avoided digging jack 6 and draw-in groove and has made the problem of curb plate and lower side board attenuation.
Of course, in order to prevent the grinding plate 5 from being pulled out of the insertion hole 6 of the upper side plate, a stopper is provided at the position of the insertion hole 6 to close the insertion hole 6, thereby achieving the mounting and fixing of the grinding plate 5. Moreover, the structures of the insertion holes 6 and the clamping grooves can be correspondingly provided with a plurality of groups so as to insert a plurality of abrasive discs 5, and three groups of the structures of the insertion grooves and the clamping grooves are arranged side by side.
The locating part is including setting up the baffle 7 in the top board and the lower side board outside, and two baffles 7 are connected with top board and lower side board displaceable respectively, change the restriction state to backplate 2 through the position that changes baffle 7. When the baffle 7 is at the first position, the baffle 7 abuts against the side surfaces of the guard plate 2 and the upper side plate, or the baffle 7 abuts against the side surfaces of the guard plate 2 and the lower side plate, so as to limit the guard plate 2 from rotating outwards, of course, the baffle 7 can be shifted to the second position, which can be the solid line position shown in fig. 2 or fig. 3, so that the baffle 7 abuts against the side surfaces of the upper side plate or the lower side plate and does not abut against the side surfaces of the guard plate 2, and thus the rotation limitation of the guard plate 2 is cancelled. Therefore, the operation is simple, and the position of the guard plate 2 can be adjusted by time and labor saving.
Further, baffle 7 rotationally connects on last curb plate and lower plate respectively through the round pin axle, and baffle 7 can use the round pin axle to rotate as the center, and baffle 7 can rotate to primary importance and second place promptly, and then realizes the spacing to backplate 2 and abrasive disc 5, and like this, this pivoted structure is easy and simple to handle, can save complicated mounting structure.
Specifically, the baffle 7 is semicircular, and the pin shaft is connected to the position of the circle center of the baffle 7, so that the baffle 7 rotates around the circle center as an axis, and the space required by rotation is favorably reduced. Moreover, the space required for the flap 7 to rotate should be kept away from the mounting position of the hinge 8.
It can be understood that the design of baffle 7 can carry on spacingly to abrasive disc 5, because baffle 7 is located the outside of epipleural, when needs restrict abrasive disc 5 in C shape frame 1, can shift baffle 7 to the third position, can be as the dotted line position in fig. 2 to make baffle 7 support in the outside of jack 6, and support in the outside of backplate 2, like this, realize a plurality of functions through a structure, be favorable to saving the process.
The edge grinder will be described in detail with reference to the above embodiments. In use, the two flaps 7 are rotated to the position shown in phantom in figures 2 and 3 to bring the two panels 2 into a parallel, i.e. closed, condition as shown in figure 5, which allows the cross-section of the material to be sanded. The upper baffle 7 is rotated to the position of the solid line in fig. 2, the lower baffle 7 is positioned at the position of the dotted line in fig. 3, the upper guard plates 2 are rotated and adjusted to form an included angle between the two guard plates 2 or to be in the vertical state shown in fig. 6, namely, the half-open state, so that corners can be polished, for example, the edge of the section glaze of a ceramic tile or the 90-degree edge of two ceramic tiles. The two baffles 7 are rotated to the solid line positions in fig. 2 and 3, and the two guard plates 2 can be adjusted to any angle or the positions shown in fig. 7, namely, the fully opened state, so that the novel grinding machine is suitable for more grinding requirements.
In some preferred embodiments, the C-shaped frame 1 further comprises a connecting plate connected between the upper side plate and the lower side plate and located on the same side of the upper side plate and the lower side plate, wherein the upper side plate, the lower side plate and the connecting plate are configured as an integrated structure. The handle 4 sets up to the sphere, and handle 4 connects on the connecting plate and keep away from one side of top plate and lower plate, and specifically, handle 4 connects in the middle part of connecting plate to it holds the control to be convenient for the user. Of course, the handle 4 may also be rectangular or ring-shaped in the shape of a lamp.
