Technical Field
The utility model relates to a spliced comb, in particular to a spliced comb with a comb back not easy to crack.
Background
The traditional spliced comb is formed by splicing wooden comb backs and tooth parts, the fiber direction of the comb backs is perpendicular to the fiber direction of the tooth parts along the length direction of the comb, when the comb backs are spliced with the tooth parts by adopting arc surfaces, most of fibers of the comb backs are truncated by the splicing surfaces, the bending strength of the comb backs is greatly reduced, when the comb moisture content is reduced, the drying shrinkage stress in the comb body is large, or when the comb body accidentally falls down, the comb backs bear instant bending moment impact, the comb backs have a tendency of bending deformation towards one side of the tooth tips, and the comb backs are easy to split from the shorter positions of the fibers, so that product quality defects are formed.
Therefore, the spliced comb solves the problem that when the spliced surface is an arc surface, the comb back is easy to crack under the action of dry shrinkage stress or under the impact of external force.
Disclosure of Invention
In view of the above, the utility model aims to provide a spliced comb with a comb back which is not easy to crack, and solve the problem that the comb back is easy to crack under the action of dry shrinkage stress or under the impact of external force when the spliced surface is an arc surface.
The spliced comb with the comb back not easy to crack comprises a spliced fixed comb back and tooth parts, wherein the spliced surfaces of the comb back and the tooth parts are arc-shaped, the comb back and the tooth parts are made of bamboo, wood or animal cutin materials, the grain direction of tooth part fibers is perpendicular to the length direction of the comb, and the comb back fibers are arranged along the arc shape of the arc-shaped spliced surface so that the fibers of the comb back are not truncated by the arc-shaped spliced surface;
further, the arc line of the arc splicing surface is provided with at least one group of concave-convex arcs along the length direction of the comb;
further, the comb backs are arranged at equal widths along the normal direction of the splicing surface.
The utility model has the beneficial effects that: according to the spliced comb with the comb back not easy to crack, the comb back fibers are arranged along the arc shape of the arc-shaped splicing surface, so that the phenomenon that the comb back fibers are cut off by the arc-shaped splicing surface is avoided, relatively complete long fiber bundles can be reserved, the comb back has good bending strength, and when the moisture content of the comb is reduced, the shrinkage stress in the comb body is large, or when the comb body accidentally falls down, the comb back is subjected to instantaneous bending moment impact, the comb back is not easy to crack.

Detailed Description
The spliced comb with the comb back not easy to crack comprises a comb back 1 and a tooth part 2 which are spliced and fixed, wherein the spliced surfaces of the comb back 1 and the tooth part 2 are arc-shaped, the comb back 1 and the tooth part 2 are made of bamboo, wood or animal cutin materials, the grain-following direction of fibers of the tooth part 2 is perpendicular to the length direction of the comb, and the fibers of the comb back 1 are arranged along the arc shape of an arc-shaped spliced surface 3 so that the fibers of the comb back 1 are not truncated by the arc-shaped spliced surface; the tooth part 2 comprises a splicing part and comb teeth, the comb teeth are distributed on the tooth part 2 at equal intervals, and the tooth part 2 and the comb back 1 are fixedly spliced along the arc-shaped splicing surface 3. Because the comb back 1 and the tooth part 2 are made of bamboo, wood or animal cutin materials, the comb has fiber directions, the fibers of the comb back 1 are arranged along the arc bending of the arc splicing surface 3, the fiber directions of the comb back 1 are consistent with the arc directions of the splicing surface, the fibers of the comb back 1 are not cut by the arc splicing surface 3, relatively complete long fiber bundles can be reserved, so that the comb back 1 has good bending strength, and when the moisture content of the comb is reduced, the dry shrinkage stress in the comb body is larger, or when the comb body accidentally falls, the comb back 1 bears instant bending moment impact, the comb back 1 is not easy to crack.
In this embodiment, the arcuate line of the arcuate splicing surface 3 has at least a group of concave-convex arcs, the fiber direction of the comb back 1 follows the undulating direction of the splicing surface, not only can satisfy the bending strength of the comb back 1, there is no phenomenon that the fiber of the comb back 1 is truncated by the splicing surface, but also the appearance is attractive.
In this embodiment, the comb back 1 is disposed with equal width along the normal direction of the splicing surface, so that the comb back 1 is easier to bend and form.
Example 1
As shown in fig. 1, the comb is in a handle-free mode, the teeth 2 are made of wood, the splicing surface is a group of concave-convex surfaces, the comb back 1 is formed by pressing wood with good thermal bending performance through a bent wood process, positioning grooves are further formed in the splicing surface of the comb back 1, positioning tenons are arranged in the splicing surface of the teeth 2, and the comb back 1 and the teeth 2 are connected through glue. In this embodiment, the fiber direction of the comb back 1 is consistent with the arc direction of the splicing surface, the fiber of the comb back 1 is not truncated by the splicing surface, and the comb back 1 has higher bending strength. In this embodiment, the comb back 1 is arranged with equal width along the normal direction of the splicing surface, so that the comb back 1 is easier to bend and form.
Example two
As shown in fig. 3, the difference from the first embodiment is that the teeth 2 are made of natural ox horn, the joint surface of the comb is three groups of continuous concave-convex surfaces, the comb back 1 is formed by pressing bamboo materials with excellent thermal bending performance through a bending process, and the fiber direction of the comb back 1 is along the undulating direction of the joint surface, and the comb back 1 and the teeth 2 are directly connected by glue.
Finally, it is noted that the above embodiments are only for illustrating the technical solution of the present utility model and not for limiting the same, and although the present utility model has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications and equivalents may be made thereto without departing from the spirit and scope of the technical solution of the present utility model, which is intended to be covered by the scope of the claims of the present utility model.
