Description

Technology Field

[0001] The present invention relates to a bolt equipped with an angle cutting function, and more specifically, to a bolt equipped with an angle cutting function that facilitates the entry of the bolt even in a narrow assembly space and provides convenience in assembly. Background Technology

[0002] Standard straight bolts consist of a bolt head and a threaded rod, and are widely used for assembling or fastening structures or machinery. These bolts are used in conjunction with nuts for tightening or are fastened directly into threaded holes within structures. Due to their simple structure and high fastening strength, straight bolts are used as fundamental fastening elements in various industrial fields.

[0003] However, straight bolts can cause various problems when assembly space is limited. For example, in narrow spaces or environments with many obstacles, work may be difficult or impossible due to insufficient space to insert or tighten bolts. In particular, during the maintenance of automobiles or machinery, if the bolt insertion space is limited, problems may arise where existing parts must be disassembled to fasten or remove the bolts.

[0004] Furthermore, straight bolts may not tighten smoothly if a sufficient radius of rotation is not secured during assembly or disassembly. For example, in the case of fixed parts such as automotive brake discs, the long length of the bolt makes it difficult to pass through the insertion hole, ultimately requiring the removal of additional parts. This problem can lead to increased work time and higher maintenance costs.

[0005] Therefore, to solve these problems, a new type of bolt that can be easily fastened and unfastened even in confined spaces is required, and the present invention aims to solve these problems by providing a bolt equipped with an angle cutting function. Prior art literature

[0006] Japanese Patent Publication No. 2024-156609 (November 6, 2024) The problem to be solved

[0007] The present invention is designed to resolve these problems and aims to provide a bolt equipped with a cutting function that facilitates easy entry of the bolt even in narrow assembly spaces and provides convenience during assembly. means of solving the problem

[0008] The present invention for achieving these objectives comprises: an upper rod provided with a bolt head;

[0009] A bolt having a cutting function is provided, characterized by comprising: a lower rod rotatably arranged with respect to the upper rod and capable of being cut relative to the upper rod; and a pivot pin rotatably connecting the upper rod and the lower rod.

[0010] It is characterized by the fact that when the lower rod is cut relative to the upper rod, it is cut in an L-shape.

[0011] A receiving groove provided at the lower part of the upper rod, and partitions provided on both sides of the receiving groove;

[0012] It is characterized by including an insertion part that is provided to protrude from the upper part of a lower rod and is inserted into a receiving groove, and a stepped part provided on both sides of the insertion part where a partition wall can be arranged, and a pivot pin hole formed in which a pivot pin is inserted into the partition wall and the insertion part.

[0013] A receiving groove provided on the upper part of the lower rod, and partitions provided on both sides of the receiving groove;

[0014] It is characterized by including an insertion part that is provided to protrude from the lower part of the upper rod and is inserted into a receiving groove, and a stepped part provided on both sides of the insertion part where a partition wall can be arranged, and a pivot pin hole formed in which a pivot pin is inserted into the partition wall and the insertion part.

[0015] The end edge of the bulkhead is provided in a curved shape, the end edge of the insertion part is also provided in a curved shape, the end of the bulkhead and the bottom surface of the stepped part are spaced apart, and the end of the insertion part and the bottom surface of the receiving groove are also spaced apart, so that an angle can be made between the upper rod and the lower rod. Effects of the invention

[0016] According to the present invention, the upper rod and the lower rod are configured to be rotatably connected, making it easy to insert a bolt even in a narrow assembly space. Therefore, the bolt can be easily fastened even in environments where it is difficult to use conventional straight bolts, thereby improving work convenience.

[0017] By designing the upper and lower rods to be angled into an L-shape, assembly and disassembly operations are possible even in narrow spaces where bolts cannot be inserted vertically. This allows workers to fasten bolts without removing surrounding parts, thereby maximizing maintenance efficiency.

[0018] By providing a receiving groove and a bulkhead at the bottom of the upper rod and designing the insertion part of the lower rod to be rotatable within the receiving groove, the angle cutting function is stably implemented. This allows the bolt to rotate to a desired angle and maintains sufficient structural strength even after fastening.

[0019] It can also be designed by providing a receiving groove and a bulkhead on the upper part of the lower rod, allowing it to be applied appropriately to various assembly environments. Therefore, various bolt designs are possible according to user needs, and the optimal fastening method can be selected based on assembly space and structural requirements.

[0020] By forming the end edges of the bulkhead and the insertion part into a curved shape, and by separating the bottom surfaces of the bulkhead and the stepped part, as well as the bottom surfaces of the insertion part and the receiving groove, interference during rotation is minimized. This allows for smooth cutting of the bolt and maintains durability even with repeated use. Brief explanation of the drawing

[0025] The above terms are used solely for the purpose of distinguishing one component from another.

[0026] For example, without departing from the scope of the present invention, the second component may be named the first component, and similarly, the first component may be named the second component.

[0027] The term "and / or" includes a combination of multiple related listed items or any of the multiple related listed items.

[0028] When it is stated that one component is "connected" or "joined" to another component, it should be understood that while it may be directly connected or joined to that other component, there may also be other components in between.

[0029] On the other hand, when it is stated that one component is "directly connected" or "directly coupled" to another component, it should be understood that there are no other components in between.

[0030] The terms used in this application are used merely to describe specific embodiments and are not intended to limit the invention.

[0031] Singular expressions include plural expressions unless the context clearly indicates otherwise.

[0032] In this application, terms such as "comprising" or "having" are intended to specify the existence of the features, numbers, steps, actions, components, parts, or combinations thereof described in the specification, and should be understood as not precluding the existence or addition of one or more other features, numbers, steps, actions, components, parts, or combinations thereof.

[0033] Hereinafter, embodiments will be described in detail with reference to the attached drawings, provided that identical or corresponding components are given the same reference number regardless of the drawing symbols, and redundant descriptions thereof will be omitted.

[0034] As illustrated in FIGS. 1 and 2, the bolt (1) having a cutting function according to the present invention comprises an upper rod (100) having a bolt head (101), a lower rod (200) rotatably provided with respect to the upper rod (100) and capable of cutting with respect to the upper rod (100), and a pivot pin (300) rotatably connecting the upper rod (100) and the lower rod (200).

[0035] Although the bolt head (101) is shown to have a hexagonal shape, its shape is not limited to this.

[0036] A receiving groove (110) and partition walls (120) provided on both sides of the receiving groove (110) are provided at the lower part of the upper rod (100). Additionally, an insertion part (210) that is provided to protrude from the upper part and is inserted into the receiving groove (110), and a stepped part (220) provided on both sides of the insertion part (210) and providing a space where the partition walls (120) can be placed are provided.

[0037] And, a pivot pin hole (130, 230) into which a pivot pin (300) is inserted is formed in the partition (120) and the insertion part (210).

[0038] That is, FIGS. 1 and 2 illustrate that a receiving groove (110) is formed in the upper rod (100) and an insertion part (210) that fits into the receiving groove (110) is formed in the lower rod (200), but it may be configured in the opposite way.

[0039] That is, although not shown, a receiving groove may be provided on the upper part of the lower rod (200), and partition walls may be provided on both sides of the receiving groove. Additionally, an insertion part provided to protrude from the lower part of the upper rod (100) and inserted into the receiving groove, and a stepped part provided on both sides of the insertion part and on which partition walls can be arranged may be further included.

[0040] In addition, a pivot pin hole into which a pivot pin is inserted can be formed in the bulkhead and the insertion part.

[0041] Although it is illustrated that no screw threads are formed on the outer surface of the upper rod (100) and screw threads (201) are formed only on the outer surface of the lower rod (200), it is not limited thereto.

[0042] In the present invention, as shown in FIG. 3, the upper rod (100) and the lower rod (200) are arranged in a straight line, but as shown in FIG. 4, when the lower rod (200) is cut off relative to the upper rod (100) (or the upper rod (100) is cut off relative to the lower rod (200)), it can be cut off in an L-shape.

[0043] In order to allow for such free angle cutting, there must be no interference between the upper rod (100) and the lower rod (200). Therefore, as shown in FIG. 5, it is preferable that the lower edge (121) of the partition wall (120) be provided in a curved shape, and the upper edge (211) of the insertion part (210) also be provided in a curved shape.

[0044] In addition, it is important that the end of the bulkhead (120) and the bottom surface of the step portion (220) are spaced apart, and the upper part of the insertion portion (210) and the upper surface of the receiving groove (110) are also spaced apart so that the upper rod (100) and the lower rod (200) can be cut apart.

[0045] Additionally, the pivot pin (300) is positioned inward from the outer surface of the upper rod (100) (or the lower rod (200) if the partition and the receiving groove are in the lower rod (200)), so that when the bolt (1) is inserted into a predetermined mating part, it does not interfere with the inner surface of the insertion hole formed in the mating part.

[0046] Below, we will explain how to use the bolt (1) equipped with the cutting function of the present invention.

[0047] As illustrated in FIG. 6, when connecting / disassembling the link assembly (L) and the fastening extension (E) provided on the wheel support (S), if the brake disc (D) is positioned outside the wheel support (S), and the distance between the brake disc (D) and the fastening extension (E) is shorter than the length when the bolt (1) is in a straight shape, then when assembling or disassembling with the existing straight bolt, the brake disc (D) must be removed.

[0048] However, in the case of the present invention, as shown in FIG. 7, the lower rod (200) passes through the fastening extension (E) while the bolt (1) is cut into an L-shape, and when the bolt (1) is rotated, the lower rod (200) of the bolt (1) is inserted into the joint (J) of the link assembly (L). Then, the upper rod (100) is positioned directly in front of the fastening extension (E) while lying down.

[0049] Then, as shown in FIG. 8, when the upper rod (100) of the bolt (1) is raised from a lying position, the upper rod (100) and the lower rod (200) are arranged in a straight line. In this state, when the bolt head (101) is tightened, as shown in FIG. 9, the upper rod (100) is inserted into the joint (J) of the connecting extension (E) and the link assembly (L), and the lower surface of the bolt head (101) comes into contact with the surface of the connecting extension (E), thereby completing the assembly. The process of disassembling the bolt (1) by loosening it can be done in the reverse order of the above sequence.

[0050] That is, when the bolt head (101) inserted into the joint (J) of the link assembly (L) is loosened while the brake disc (D) is positioned outside the wheel support (S), only the upper rod (100) is exposed outside the fastening extension (E) as shown in FIG. 8, and in this state, if the upper rod (100) is laid down as shown in FIG. 7 and then rotated, the bolt that is cut into an L shape as shown in FIG. 6 can be pulled out to the outside.

[0051] By providing a bolt (1) that can be cut into an L-shape like this, there is an advantage that the assembly or disassembly of the bolt can be made easy even in narrow spaces where it is unsuitable to use a straight bolt.

[0052] Although the present invention has been described above with reference to the embodiments illustrated in the drawings, this is merely for the purpose of explaining the invention, and those skilled in the art will understand that various modifications or equivalent embodiments are possible from the detailed description of the invention.

[0053] Therefore, the true scope of rights of the present invention must be determined by the technical concept of the patent claims. Explanation of the symbols
