Description

Technical Field

[0001] The utility model relates to the technical field of channel steel fasteners, in particular to a non-standard channel steel fastener. Background Technique

[0002] Channel steel is a long steel with a grooved cross-section, which is mainly used in building structures, curtain wall projects, mechanical equipment and vehicle manufacturing, etc.

[0003] A channel steel fastener is a connecting piece for quickly connecting accessories to channel steel. The channel steel fastener is installed inside the channel steel by rotation and embedding, and can be adjusted arbitrarily on the channel steel;

[0004] In actual use, if the position of the channel steel fastener needs to be adjusted, the channel steel fastener needs to be rotated to a state where it is not perpendicular to the long side direction of the channel steel by 90 degrees. At this time, the channel steel fastener is not pressed against the inner wall side of the channel steel, so the channel steel fastener can be moved. When the channel steel fastener is rotated to be parallel to the long side direction of the channel steel, the channel steel fastener is aligned with the notch of the channel steel, and at this time the channel steel fastener can be removed from the notch of the channel steel. Although such a structure facilitates the disassembly and assembly of the channel steel fastener, when adjusting the position of the channel steel fastener, it is also easy for the channel steel fastener to fall out of the channel steel. To avoid this situation, a non-standard channel steel fastener is provided. Content of the Utility Model

[0005] The purpose of the utility model is to provide a non-standard channel steel fastener to solve the problems in the above background.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a non-standard channel steel fastener, including a channel steel fastener composed of a fastener main body, a threaded hole, and long strip teeth. The threaded hole is opened in the middle of the fastener main body and penetrates through the upper and lower ends of the fastener main body. The long strip teeth are symmetrically formed on both sides of the bottom of the fastener main body with the threaded hole as the center. An auxiliary fastener is arranged on the outer side of the fastener main body, and the auxiliary fastener is used to assist the installation of the fastener main body into the channel steel;

[0007] The auxiliary fastener includes a disassembly and assembly unit and a limiting unit;

[0008] The disassembly and assembly unit is used to realize the quick disassembly and assembly of the fastener main body and the channel steel and the convenient adjustment of the position of the fastener main body;

[0009] The limiting unit is used to limit between the disassembly and assembly unit and the channel steel, so as to avoid the situation of the fastener main body falling during the process of position adjustment.

[0010] As a further scheme of the utility model: the disassembly and assembly unit includes a socket cylinder, an outer gasket, a force-applying convex block, and a horizontal through groove;

[0011] The horizontal through groove is formed inside the socket cylinder column and penetrates to both sides outside the socket cylinder column. The socket cylinder column is sleeved and installed on the outside of the buckle body through the horizontal through groove;

[0012] The outer gasket is fixed to the outside of the bottom of the socket cylinder column. The force-applying bumps are symmetrically fixed to both ends of the bottom of the outer gasket. The force-applying bumps are used to provide a hand-held pushing force point for the user, so as to realize the rotation and movement operations of the buckle body.

[0013] As a further solution of the present invention: The limiting unit includes a vertical receiving groove and an arc-shaped elastic sheet;

[0014] The vertical receiving grooves are symmetrically formed at both ends of the outer wall of the socket cylinder column. The top of the arc-shaped elastic sheet is fixed to the top of the inner wall of the vertical receiving groove. The middle arc surface of the arc-shaped elastic sheet protrudes to the outside of the socket cylinder column. The bottom of the arc-shaped elastic sheet is received inside the vertical receiving groove;

[0015] When the socket cylinder column is inserted into the channel steel, the arc-shaped elastic sheet is deformed and contracted under the extrusion force. When the arc-shaped elastic sheet enters the channel steel, the arc-shaped elastic sheet resets, and the downward movement of the socket cylinder column is limited by the clamping connection between the arc-shaped elastic sheet and the inner wall of the channel steel.

[0016] As a further solution of the present invention: The bottom horizontal height of the arc-shaped elastic sheet in the initial state matches the bottom horizontal height of the buckle body;

[0017] The height of the vertical receiving groove is greater than the height of the arc-shaped elastic sheet.

[0018] As a further solution of the present invention: The socket cylinder column, the outer gasket, the force-applying bumps, the horizontal through groove, the vertical receiving groove, and the arc-shaped elastic sheet are integrally formed by an injection molding process. The buckle body and the long strip teeth are integrally formed by a cold pressing process.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] By setting the auxiliary fastener, the convenient disassembly, assembly and position adjustment of the channel steel buckle can be realized. Through the clamping of the arc-shaped elastic sheet with the upper edge of the channel opening of the channel steel, the situation of falling during the position adjustment of the buckle body can be effectively avoided, and the convenience of the installation operation of the channel steel buckle is effectively improved.

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1 to 4 , in the embodiment of the present utility model, a non-standard channel steel lock includes a channel steel lock 1 composed of a lock body 101, a threaded hole 102, and long strip teeth 103. The threaded hole 102 is opened in the middle of the lock body 101 and penetrates through the upper and lower ends of the lock body 101. The long strip teeth 103 are symmetrically formed on both sides of the bottom of the lock body 101 with the threaded hole 102 as the center. An auxiliary fastener 2 is arranged on the outer side of the lock body 101, and the auxiliary fastener 2 is used to assist the installation of the lock body 101 into the channel steel;

[0028] The auxiliary fastener 2 includes a disassembly and assembly unit and a limiting unit;

[0029] The disassembly and assembly unit is used to realize the rapid disassembly and assembly of the lock body 101 and the channel steel and the convenient adjustment of the position of the lock body 101;

[0030] The limiting unit is used to limit between the disassembly and assembly unit and the channel steel, so as to prevent the lock body 101 from falling during the position adjustment process;

[0031] The disassembly and assembly unit includes a socket cylinder column 201, an outer gasket 202, a force-applying convex block 203, and a horizontal through groove 204;

[0032] The horizontal through groove 204 is formed on the inner side of the socket cylinder column 201 and penetrates to both sides of the outside of the socket cylinder column 201. The socket cylinder column 201 is sleeved and installed on the outer side of the lock body 101 through the horizontal through groove 204;

[0033] The outer gasket 202 is fixed to the outer side of the bottom of the socket cylinder column 201, and the force-applying bumps 203 are symmetrically fixed to both ends of the bottom of the outer gasket 202. The force-applying bumps 203 are used to provide a hand-held pushing force point for the user, so as to realize the rotation and movement operations of the lock body 101;

[0034] The limiting unit includes a vertical receiving groove 205 and an arc-shaped elastic sheet 206;

[0035] The vertical receiving grooves 205 are symmetrically formed at both ends of the outer wall of the socket cylinder column 201. The top of the arc-shaped elastic sheet 206 is fixed to the top of the inner wall of the vertical receiving groove 205. The middle arc surface of the arc-shaped elastic sheet 206 protrudes to the outside of the socket cylinder column 201, and the bottom of the arc-shaped elastic sheet 206 is received inside the vertical receiving groove 205;

[0036] When the socket cylinder column 201 is inserted into the channel steel, the arc-shaped elastic sheet 206 is deformed and contracted under the extrusion force. When the arc-shaped elastic sheet 206 enters the channel steel, the arc-shaped elastic sheet 206 resets, and the downward movement of the socket cylinder column 201 is limited by the clamping connection between the arc-shaped elastic sheet 206 and the inner wall of the channel steel.

[0037] In this embodiment: It should be added that the arc-shaped elastic sheet 206 and the lock body 101 are vertically distributed;

[0038] When installing the lock body 101 into the channel steel, the hand can be pinched on the force-applying bumps 203, align the lock body 101 with the notch of the channel steel and insert it. During this process, the arc-shaped elastic sheet 206 protruding to the outside of the socket cylinder column 201 will be squeezed by the channel steel. At this time, the arc-shaped elastic sheet 206 is deformed and contracted under the force, so that the socket cylinder column 201 can be smoothly inserted into the channel steel. When the lock body 101 completely enters the channel steel along with the movement of the socket cylinder column 201, the arc-shaped elastic sheet 206 loses the external extrusion force and will reset under its own elastic force, so that the arc-shaped elastic sheet 206 protrudes to the outside of the socket cylinder column 201 again. At this time, the arc-shaped elastic sheet 206 will be engaged with the upper edge of the notch of the channel steel, that is, when the hand-held force on the force-applying bumps 203 is released, the whole channel steel lock will not fall off. Through this structure, it can effectively avoid the situation of falling during the position adjustment of the lock body 101;

[0039] When it is necessary to fix the lock body 101, only need to apply a deflection force to the force-applying bumps 203 to make the lock body 101 rotate to a state perpendicular to the channel steel. At this time, the lock body 101 is closely attached to the inside of the channel steel (it should be noted that the two diagonals on both sides of the lock body 101 are arc-shaped structures, and the other two diagonals are right-angled structures, so that the lock body 101 can rotate 90 degrees inside the channel steel), and then connect the accessories to the lock body 101 through external bolts.

[0040] Please refer to Figures 1 to 4, the bottom horizontal height of the arc-shaped elastic piece 206 in the initial state matches the bottom horizontal height of the buckle body 101, and the height of the vertical storage groove 205 is greater than the height of the arc-shaped elastic piece 206.

[0041] In this embodiment: By making the bottom horizontal height of the arc-shaped elastic piece 206 in the initial state match the bottom horizontal height of the buckle body 101, when the arc-shaped elastic piece 206 returns to the initial state inside the channel steel, the bottom of the arc-shaped elastic piece 206 fits against the upper part of the edge of the notch of the channel steel, ensuring that the buckle body 101 is located above the notch of the channel steel, thus facilitating the later rotation and fixing operation of the buckle body 101;

[0042] The structure with the height of the vertical storage groove 205 being greater than the height of the arc-shaped elastic piece 206 is used to provide space for the deformation of the arc-shaped elastic piece 206.

[0043] Please refer specifically to Figures 1 to 4 , the socket cylinder column 201, the outer gasket 202, the force-applying convex block 203, the horizontal through groove 204, the vertical storage groove 205, and the arc-shaped elastic piece 206 are integrally formed by injection molding, and the buckle body 101 and the long strip teeth 103 are integrally formed by cold pressing.

[0044] In this embodiment: This structure makes the production processes of the channel steel buckle 1 and the auxiliary fastener 2 simple. After production, they can be assembled with each other. Overall, the production steps are few, which is convenient for popularization and production.

[0045] The above-mentioned is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
