Description

Technical Field

[0001] This utility model belongs to the field of daily necessities technology, and in particular relates to a comb. Background Technology

[0002] Combs, as a common hair grooming tool, have been used for thousands of years, and are mostly made of wood, plastic, or metal. In existing technology, such as the wooden comb disclosed in CN307341698S, there is a wooden comb body, a plastic sheet, and comb needles. The wooden comb body has grooves, the plastic sheet is fitted into the grooves, and the base of the comb needles is fixedly connected to the plastic sheet. Its cross-section is shown below. Figure 1 As shown.

[0003] In actual manufacturing, due to the manufacturing tolerances between the dimensions of the slot and the plastic piece, it is difficult for the plastic piece to achieve a fully tight contact with the inner wall of the slot when it is inserted into the slot, which easily creates tiny gaps. During daily use, moisture may seep into the wooden comb through these gaps. This moisture is difficult to clean and can easily lead to mold growth on the wooden parts over time, which is detrimental to the longevity of the comb. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a comb with good waterproof sealing, which helps to extend its service life.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a comb, including a wooden comb body, a fixing plate and a plurality of comb needles, wherein the wooden comb body is provided with a slot, the fixing plate is engaged with the slot and located at the bottom of the slot, the slot is filled with a resin layer covering the fixing plate, the resin layer is provided with a plurality of perforations, the perforations correspond one-to-one with the comb needles, and the root of the comb needle passes through the corresponding perforation and is fixedly connected to the fixing plate.

[0006] Preferably, the fixing piece is a plastic sheet.

[0007] Preferably, the fixing piece is provided with a flow channel on the side facing the bottom of the slot, and a first through hole is provided on the side facing the opening of the slot. The first through hole is connected to the flow channel, and a first insert is integrally provided on the resin layer, extending into the first through hole and the flow channel.

[0008] Preferably, the flow channels are provided in multiple ways, and the multiple flow channels are distributed in an intersecting manner.

[0009] Preferably, the fixing piece has a plurality of parallel protrusions on the side facing the bottom of the slot, and a filling cavity is formed between two adjacent protrusions. The fixing piece has a second through hole on the side facing the slot opening, and the second through hole communicates with the filling cavity. A second insert is integrally formed on the resin layer, extending into the second through hole and the filling cavity.

[0010] Preferably, the upper surface of the resin layer is flush with the opening of the slot.

[0011] Compared with the prior art, the advantages of this utility model are as follows: by adding a resin layer inside the card slot, the resin can fill the card slot when it is in liquid state, and after the resin is cured, it can fully and tightly contact the inner wall of the card slot, avoiding the formation of micro gaps, preventing water vapor from seeping into the card slot, and providing good waterproof sealing. With long-term use, the wooden parts are not easy to get damp and moldy, which helps to extend the service life. Attached Figure Description

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] Example 1: As Figures 2 to 4 As shown, a comb includes a wooden comb body 1, a fixing plate 2, and a plurality of comb needles 3. The wooden comb body 1 has a groove 11. The fixing plate 2 engages with the groove 11 and is located at the bottom of the groove 11. The groove 11 is filled with a resin layer 4 covering the fixing plate 2. The resin layer 4 has a plurality of perforations 41, each corresponding to a comb needle 3. The base of the comb needle 3 passes through the corresponding perforation 41 and is fixedly connected to the fixing plate 2. The fixing plate 2 is preferably a plastic sheet.

[0024] In this embodiment, the upper surface of the resin layer 4 is flush with the opening of the slot 11.

[0025] During the manufacturing process of this comb, a groove 11 is first made on the wooden comb body 1, and a fixing piece 2 is inserted into the groove 11. Then, liquid resin is poured in, and after the resin cures, perforations 41 are made in the resin. Finally, comb needles 3 are inserted, and the base of the comb needles 3 is passed through the perforations 41 and fixedly connected to the fixing piece 2. Because the resin can fill the groove 11 when it is in liquid state, and can fully and tightly contact the inner wall of the groove 11 after the resin cures, it avoids the formation of tiny gaps and prevents moisture from seeping into the groove 11.

[0026] Example 2: Figure 5 and Figure 6 As shown, the rest is the same as in Embodiment 1, except that the fixing piece 2 has a flow channel 21 on the side facing the bottom of the slot 11, and a first through hole 22 on the side facing the opening of the slot 11. The first through hole 22 is connected to the flow channel 21, and a first insert 42 extending into the first through hole 22 and the flow channel 21 is integrally formed on the resin layer 4. The first through hole 22 is offset from the through hole 41.

[0027] In this embodiment, multiple flow channels 21 are provided, and the multiple flow channels 21 are distributed in an intersecting manner. Multiple first through holes 22 are provided, and the first through holes 22 are preferably located at the intersection of the flow channels 21.

[0028] During processing, the poured liquid resin will simultaneously fill the first through hole 22 and the flow channel 21. After the resin cures, the resin in the first through hole 22 and the flow channel 21 forms the first insert 42, which can improve the bonding strength between the resin layer 4 and the fixing piece 2, making the comb structure more stable and reliable.

[0029] Example 3: Figure 7 and Figure 8 As shown, the rest is the same as in Embodiment 1, except that the fixing piece 2 has multiple parallel protrusions 23 on the side facing the bottom of the slot 11, and a filling cavity is formed between two adjacent protrusions 23. The fixing piece 2 has a second through hole 24 on the side facing the opening of the slot 11, and the second through hole 24 communicates with the filling cavity. A second insert 43 extending into the second through hole 24 and the filling cavity is integrally formed on the resin layer 4. The protrusions 23 are integrally formed with the fixing piece 2, and the second through hole 24 is staggered from the through hole 41.

[0030] During processing, the poured liquid resin will simultaneously fill the second through hole 24 and the filling cavity. After the resin cures, the resin in the second through hole 24 and the filling cavity forms the second insert 43, which can improve the bonding strength between the resin layer 4 and the fixing piece 2, making the comb structure more stable and reliable.

[0031] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the implementation of the present invention is not limited to the above-described manner. Any improvements made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
