Description

Technical Field

[0001] The utility model relates to the field of razors, in particular to a straight razor with a safety adjustment rod. Background Art

[0002] In the beauty and hairdressing industry, razors are often used in men's haircut / shaving services. Common manual razors on the market usually include a handle and a blade installed at the end of the handle, such as a convenient razor with authorization announcement number CN215318839U. Barbers / shaving technicians need to have years of accumulated work experience and learn shaving techniques. They can stably control the angle of the razor and the strength of their wrists to shave customers, so that customers can enjoy satisfactory and comfortable services. Since ordinary manual razors do not have other safety components, it is difficult for less experienced barbers / shaving technicians to grasp the angle of the razor and the strength of their wrists, and it is difficult to find the best angle for shaving. If the angle is not well grasped, the sharp blade may scratch the customer's skin during operation, reducing the customer experience. Utility Model Content

[0003] The purpose of the utility model is to provide a straight razor with a safety adjustment rod, which is a technical point of adding an adjustment rod to an ordinary manual razor.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1 to 6 The utility model provides a technical solution: a straight razor with a safety adjustment rod, comprising a handle 1, a blade base 2 installed at the end of the handle 1, and a blade cover 3 installed on the blade base 2, a blade 7 is clamped between the blade cover 3 and the blade base 2, and also includes an adjustment rod 4 for contacting against human skin, the adjustment rod 4 is rotatably connected to the blade base 2 through a bent extension part 41; and also includes a limit assembly for limiting the position of the adjustment rod 4 away from and / or close to the exposed side of the blade 7.

[0022] In this embodiment, the adjustment rod 4 can be specifically a U-shaped rod, and the bent extension portion 41 of the adjustment rod 4 extending away from the handle end is rotatably connected to the external hinge seat 21 at the end of the blade base 2, and the end of the blade cover 3 is provided with a groove portion 33 for matching the shape of the external hinge seat 21.

[0023] The working principle of the utility model is as follows: by pressing the adjusting rod 4 to rotate it around the blade base 2, the angle of the adjusting rod 4 is adjusted, and the angle of the adjusting rod 4 is limited by the limiting assembly. When shaving, the middle section of the adjusting rod 4 is used to contact the skin, which can provide preliminary support for the blade base 2, making it easy for the barber / shaving technician to quickly and accurately find the best shaving angle, greatly reducing the risk of skin scratches on customers caused by the blade 7 due to lack of technical experience during shaving, thereby improving the safety and experience during shaving.

[0024] As a specific solution, an insert rod 25 extends from one end of the blade base 2 close to the handle 1, and the insert rod 25 is inserted and fixed in the handle 1. The end surface of the handle 1 is provided with at least two gear slots 11 for cooperating with the end of the adjustment rod 4; the limiting assembly includes a limiting spring 5 sleeved on the insert rod 25 and a limiting plate 6 for pushing the end of the adjustment rod 4. One end of the limiting spring 5 contacts the blade base 2, and the other end of the limiting spring 5 is connected to the limiting plate 6. The limiting plate 6 is used to press the end of the adjustment rod 4 against the gear slot 11 under the action of the limiting spring 5. The structural design of the limiting assembly is reasonable. The elastic force of the limiting spring 5 is used to enable the limiting plate 6 to push the end of the adjustment rod 4, so that it is limited to the gear slot 11, and the adjustment rod 4 is prevented from rotating at will.

[0025] In this embodiment, two gear slots 11 are specifically provided, symmetrically distributed on both sides of the plane where the blade 4 is located. When the end of the adjustment rod 4 is pressed against the gear slot 11, the angle between the plane where the adjustment rod 4 is located and the plane where the blade 7 is located can be specifically 5-12 degrees. Obviously, during the design and production, the limiting angle of the gear slot 11 can be obtained through multiple tests and experiments. The gear slots 11 on both sides of the blade 4 limit the angle of the adjustment rod 4. When using the straight razor of this embodiment, whether it is along the razor (such as Figure 5 ), or against the razor (such as Figure 6 ), even less experienced barbers / shaving technicians can accurately and safely perform shaving and trimming work. The straight razor of this embodiment, with the cooperation of the adjusting rod 4, can greatly reduce the possibility of the sharp blade scratching the skin due to excessive shaving angle.

[0026] As a further specific solution, a second gear slot 12 is opened on the end face of the handle 1. When the end of the adjusting rod 4 is rotated into the second gear slot 12, the middle section of the adjusting rod 4 is away from the exposed side of the blade 7, which can facilitate the subsequent disassembly of the blade cover 3 and the blade 7.

[0027] In order to facilitate the assembly and disassembly of the blade cover 3 and the blade 7, in this embodiment, a spring piece receiving groove and a blade receiving groove are distributed on the inner side of the blade base 2, a pair of internal socket seats 22 are distributed on the inner side of the blade base 2 between the spring piece receiving groove and the blade receiving groove, and a latch shaft 31 for cooperating with the internal socket seats 22 is distributed on the inner side of the blade cover 3; a spring piece 24 is installed in the spring piece receiving groove, and the spring piece 24 is used to push the blade cover 3 so that the other side of the blade cover 3 presses the blade 7 into the blade receiving groove. Specifically, in order to limit the spring piece 24, a convex column 23 is provided in the spring piece receiving groove, and a hole for sleeved on the convex column 23 is provided on the spring piece 24.

[0028] In order to stably limit the position of the plane where the blade 7 is located, limiting holes 71 are distributed on the blade 7, and limiting blocks 32 for cooperating with the limiting holes 71 are distributed on the inner side of the blade cover 3.

[0029] The assembly process of the blade cover 3 and the blade 7 is as follows: first, rotate the end of the adjustment rod 4 to the gear slot 12, then place the blade 7 in the blade accommodating slot, then, push the blade cover 3 along the axial direction of the internal socket seat 22, so that the pin shaft 31 of the blade cover 3 is inserted into the internal socket seat 22, loosen the blade cover 3, and the blade cover 3 rotates around the internal socket seat 22 under the elastic force of the spring piece 24, and the other side of the blade cover 3 can press the blade 7 into the blade accommodating slot, thereby completing the assembly.

[0030] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
