Description

Technical Field

[0001] The present invention relates to the technical field of fasteners, and specifically to a stainless-steel fastener with adjustable length. Background Art

[0002] Fasteners are a type of mechanical parts used for fastening connections and are extremely widely applied. Stainless-steel material is a corrosion-resistant material. Fasteners made of stainless steel have characteristics such as durability and strong corrosion resistance, and are widely used.

[0003] In a stainless-steel fastener with adjustable length disclosed in the authorized publication number CN219888455U, it includes a first stud. The upper end of the first stud is detachably connected with a first screw head. A connection hole is opened at the upper end of the first stud. A second stud is provided at the upper end of the first stud. The lower end of the second stud is fixedly connected with a connection post adapted to the connection hole. The connection post and the connection hole are in threaded connection. The end of the second stud away from the first stud is fixedly connected with a second screw head. By setting the detachable first screw head in the above-mentioned fastener, when the length of the first stud is insufficient, the first screw head is removed, and the second stud is in threaded connection with the connection hole through the connection post. When the connection post is tightened, the thread on the second stud is adapted to the thread on the first stud. By installing the second stud, the length of the first stud is extended, and thus different installation positions can be adapted. The range of fastener models required during installation is greatly reduced, achieving the effect of reducing the procurement cost of fasteners. Although the length of the fastener can be adjusted above, the adjusted fastener only simply extends through the second stud, and the length of the fastener that can be adjusted has only two gears (one gear is the length of the first stud, and the other gear is the length of the first stud plus the second stud). Therefore, the inventiveness of this fastener is limited.

[0004] Therefore, we propose a stainless-steel fastener with adjustable length to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to solve the problems existing in the prior art, and to propose a stainless-steel fastener with adjustable length, which can adjust more different length gears and improve the inventiveness of this fastener.

[0006] To achieve the above purpose, the present invention adopts the following technical solution:

[0007] A stainless-steel fastener with adjustable length includes a threaded post. The upper end of the threaded post is fixedly connected with a hexagonal rod. A limiting sleeve is slidably sleeved on the outer wall of the hexagonal rod. A plurality of through holes are opened on the outer wall of the hexagonal rod. A through hole matching the through hole is opened on the outer wall of the limiting sleeve, and a limiting rod is slidably connected in the through hole. One end of the limiting rod passes through the through hole.

[0008] Preferably, a threaded hole is formed in the outer wall of the limiting sleeve, a relief hole communicating with the through hole is formed in the outer wall of the hexagonal rod, a screw is threadedly connected to the inner wall of the threaded hole, and one end of the screw passes through the relief hole and abuts against the limiting rod.

[0009] Preferably, one end of the limiting sleeve is fixedly connected with a hexagonal block.

[0010] Preferably, a hexagonal hole is formed in the upper surface of the hexagonal block.

[0011] Preferably, a chamfer is formed at one end of the hexagonal rod.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In the present invention, by arranging a plurality of through holes, through holes and limiting rods to cooperate with each other, the length of the fastener can be adjusted as needed during use. At the same time, due to the arrangement of a plurality of through holes, the fastener can be adjusted to a plurality of different length segments, improving the inventiveness of the fastener.

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-4, A stainless-steel fastener with adjustable length, including a threaded post 1. The upper end of the threaded post 1 is fixedly connected with a hexagonal rod 2. A limiting sleeve 3 is slidably sleeved on the outer wall of the hexagonal rod 2. A plurality of through holes 4 are opened on the outer wall of the hexagonal rod 2. A through hole 5 matching the through hole 4 is opened on the outer wall of the limiting sleeve 3. A limiting rod 6 is slidably connected in the through hole 5, and one end of the limiting rod 6 passes through the through hole 4 and is arranged.

[0021] It can be seen from the above structure that by setting a plurality of through holes 4, through holes 5 and limiting rods 6 to cooperate with each other, the length of the fastener can be adjusted as needed during use. At the same time, due to the setting of a plurality of through holes 4, the fastener can be adjusted into multiple different length segments. (The number of through holes 4 is the number of length gears that the fastener can adjust. The more through holes there are, the more different lengths can be adjusted), which improves the inventiveness of the fastener. During use, as needed, pry open the limiting rod 6, then pull the limiting sleeve 3, pull the limiting sleeve 3 to the required height, and then make the limiting rod 6 pass through the through hole 4 and the through hole 5. By passing the limiting rod 6 through different through holes 4, the fastener can be adjusted to different lengths.

[0022] Furthermore, a threaded hole 7 is opened on the outer wall of the limiting sleeve 3. A relief hole 8 communicating with the through hole 4 is opened on the outer wall of the hexagonal rod 2. A screw 9 is threadedly connected to the inner wall of the threaded hole 7, and one end of the screw 9 passes through the relief hole 8 and abuts against the limiting rod 6. By setting the screw 9, the limiting rod 6 can be limited to prevent the limiting rod 6 from randomly disengaging from the through hole 4 and the through hole 5.

[0023] Furthermore, one end of the limiting sleeve 3 is fixedly connected with a hexagonal block 10. By setting the hexagonal block 10, when rotating the limiting sleeve 3 and the threaded post 1, a wrench can be used to cooperate with the hexagonal block 10 for rotation.

[0024] Furthermore, a hexagonal hole 11 is opened on the upper surface of the hexagonal block 10. By opening the hexagonal hole 11, when the corner of the hexagonal block 10 is damaged and cannot be rotated by a wrench, an internal hexagonal wrench can be used to cooperate with the hexagonal hole 11 to rotate the limiting sleeve 3 and the threaded post 1, etc.

[0025] Furthermore, a chamfer is opened at one end of the hexagonal rod 2. By opening the chamfer, it is convenient for the hexagonal rod 2 to be inserted into the limiting sleeve 3.

[0026] It is obvious to those skilled in the art that the present invention is not limited to the details of the above-described exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, in all respects, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description.
