Detailed Description

In order to make the technical solution of the present utility model more clear and obvious to those skilled in the art, the present utility model will be described in further detail with reference to examples and drawings, but the embodiments of the present utility model are not limited thereto.

As shown in fig. 1 to 4, the paint brush provided in this embodiment includes a brush handle 1 and a brush head 2 which are adjacently distributed, and are made of wood material and integrally formed;

the top end of the brush handle 1 is connected with the bottom surface of the brush head 2, the top surface of the brush head 2 is provided with a square caulking groove 3, the edge of the caulking groove 3 is not overlapped with the edge of the brush head 2, and a bristle fixing block 4 which is a plastic piece is arranged in the caulking groove 3;

the top surface of the bristle fixing block 4 is uniformly provided with a plurality of square bristle fixing holes 5 (the bristle fixing block 4 and the bristle fixing holes 5 are integrally injection molded), wherein the distance between two adjacent bristle fixing holes 5 can be 1 mm-1.5 mm, and the bristle fixing holes are plastic parts, so that even if the distance between two adjacent bristle fixing holes 5 is small, the structure of the wooden brush head is not fragile due to thinning, or the problems of shrinkage, expansion and the like are easy to occur due to the influence of temperature and humidity, and the height direction of the bristle fixing holes 5 is consistent with the height direction of the brush head 2 so as to ensure that the height direction of bristles 6 is the same as the height direction of the brush head 2;

the heights of the top ends of two adjacent bristle fixing holes 5 along the width direction of the bristle fixing block 4 are different, and the heights of the bottom ends are also different (the heights of the bottom ends of the bristle fixing holes 5 from left to middle are gradually increased, and the heights of the bottom ends of the bristle fixing holes 5 from middle to right are opposite), so that after a plurality of bundles of bristles 6 with the same length (one bristle fixing hole corresponds to one bundle of bristles and one bundle of bristles consists of a plurality of bristles) are respectively inserted into the bristle fixing holes 5 at different positions, the plurality of bundles of bristles 6 distributed along the width direction of the brush head 2 are distributed in an arc shape (namely, the two sides are low and the middle is high), and the surface formed by the top ends of the bristles 6 on the brush head 2 is an arc surface instead of a plane, so that the bristle utilization rate can be improved, and the using effect of the paint brush can be improved;

the outer side of the bristle fixing block 4 is provided with a plurality of first damping pieces 701 (which can be of a plastic block structure with inclined planes) distributed at intervals along the height direction, the plurality of first damping pieces 701 can form a saw-tooth structure, when the bristle fixing block 4 is embedded into the caulking groove 3, the first damping pieces 701 are tightly attached to the inner wall of the brush head 2, the first damping pieces 701 are extruded, and the saw-tooth structure can prevent the bristle fixing block 4 from falling off from the inside of the brush head 2.

In this embodiment, two rectangular limiting holes 10 are formed at the inner bottom side of the brush head 2 at intervals, two connecting columns 9 are fixed on the bottom side surface of the bristle fixing block 4, each connecting column 9 is inserted into the corresponding limiting hole 10, one or more second damping members 702 (may be a plastic block structure with inclined surfaces) are arranged at the outer side surface of each connecting column 9 at intervals along the height direction, the plurality of second damping members 702 can form a saw-tooth structure, when the bristle fixing block 4 is embedded into the embedding groove 3, the connecting columns 9 are firstly embedded into the corresponding limiting holes 10, at this time, the second damping members 702 are tightly attached to the limiting holes 10 and are extruded, and thus the connection stability between the bristle fixing block 4 and the brush head 2 is reinforced.

In this embodiment, the bristle fixing hole 5 is in a quadrangular structure, the diameter of the bristle fixing hole is gradually reduced from top to bottom (or the inner diameter of the bristle fixing hole is unchanged from top to bottom), after the bundled bristles 6 are inserted into the bristle fixing hole 5, the iron sheet 8 is propped between the bristles 6 and the bristle fixing hole 5 and pressed, so that the iron sheet 8 interacts with the bristle fixing hole 5, the position of the iron sheet 8 is firm, in the process, the iron sheet 8 cooperates with the inner wall of the bristle fixing hole 5 to squeeze the bristles, so that the bristles 6 are fixed in the bristle fixing hole 5, the iron sheet 8 can be in a cuboid sheet/block structure, the width of the iron sheet 8 is smaller than the inner diameter of the bristle fixing hole 5, so that the bristles 6 are conveniently inserted into the bristle fixing hole 5 and fixed in the bristle fixing hole, and no fixing objects such as glue are needed in the process of fixing the bristles 6.

In another embodiment, the bristle fixing holes are in a waist-shaped structure with a large top diameter, a small middle diameter and a large bottom diameter, namely, the middle part is a contraction part, and after the 'bundled' bristles 6 are inserted into the bottom space from the top of the bristle fixing holes, the bristles 6 are extruded by the contraction part, so that the bristles are fixed without using a fixture such as glue.

In another embodiment, the bristle holder 4 is high at the middle and low at both sides, and the top surface of the middle portion is a plane.

In summary, in this embodiment, the bristle fixing block provided in this embodiment is embedded in the caulking groove on the brush head, and the bristle fixing block is a plastic piece, when the bristle fixing block is perforated, even if the distance between two adjacent holes is small, there is no fear that the joint between two holes will break, so that the density of bristles on the bristle fixing block can be effectively increased, and the number of bristle bundles is increased, so as to improve the brushing efficiency.

The above description is merely a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto, and any person skilled in the art will be able to apply equivalents and modifications according to the technical solution and the concept of the present utility model within the scope of the present utility model disclosed in the present utility model.
