Description

Technical Field

[0001] This utility model relates to the field of stainless steel fastener technology, and in particular to a stainless steel fastener with adjustable length. Background Technology

[0002] Existing adjustable-length stainless steel fasteners, while convenient to use due to their structural design, do not allow for direct addition or removal of connecting parts as needed. The required adjustment length must be confirmed, and finding a threaded post of the appropriate length is inefficient. For example, Chinese patent disclosure "An Adjustable-Length Stainless Steel Fastener" (application number: CN202321613176.5) includes a first stud with a first threaded head detachably connected to its upper end. A connecting hole is provided at the upper end of the first stud. A second stud is located at the upper end of the first stud, and a connecting post adapted to the connecting hole is fixedly connected to its lower end. The connecting post and the connecting hole are threaded together. A second threaded head is fixedly connected to the end of the second stud furthest from the first stud. While this structure facilitates use, it still limits its application as it requires confirming the adjustable length and finding a threaded post of the appropriate length, making it inefficient. Utility Model Content

[0003] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a stainless steel fastener with adjustable length. By setting up column one, column two, column three, slot one, locking post, locking plate, fixing hole, through hole and fixing post, it is convenient to add multiple columns two as needed to extend its length, avoiding the need to determine the length to be adjusted and find the corresponding threaded post when adjustment is needed.

[0004] This utility model also provides a stainless steel fastener with an adjustable length as described above, comprising: a first column, a second column below the first column, and a third column below the second column. Each of the first and second columns has a slot, in which a locking post engages. A locking plate is fixedly connected to the lower surface of the locking post, and the locking plate is fixedly connected to the upper surfaces of the second and third columns. Each of the first and second columns has a fixing hole, and the locking post has a through hole. A fixing post is disposed within the fixing hole, passing through the through hole and extending into the fixing hole on the other side of the locking post. This structure allows for the addition of multiple second columns as needed to extend the length, avoiding the need to determine the adjustment length and find the corresponding threaded post when adjustment is required.

[0005] According to the present invention, an adjustable-length stainless steel fastener has a fixing block fixedly connected to one upper surface of the column, and a screw head fixedly connected to the upper surface of the fixing block. The above structure facilitates tightening.

[0006] According to the present invention, an adjustable-length stainless steel fastener has threads on three sides of the column body, which facilitates the fixing of the whole.

[0007] According to the present invention, an adjustable-length stainless steel fastener is provided on both the first and second columns, and the clamping plate is located in the groove. The connection position of the clamping plate is determined by the above structure.

[0008] According to the present invention, an adjustable-length stainless steel fastener is provided on both column one and column two, and a locking block is engaged in the locking slot two. The above structure facilitates engagement.

[0009] According to the present invention, an adjustable-length stainless steel fastener has a locking block fixedly connected to the upper surface of a locking plate and distributed in a ring around the axis of the locking plate. This structure facilitates the determination of the position of the locking block.

[0010] Beneficial effects:

[0011] Compared with existing technologies, this adjustable-length stainless steel fastener, by having a column 1, a column 2, a column 3, a slot 1, a locking post, a locking plate, a fixing hole, a through hole, and a fixing post, allows for the addition of multiple columns 2 as needed to extend its length, avoiding the need to determine the adjustment length and then find the corresponding threaded post when adjustment is required.

[0019] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0020] Reference Figure 1-4 This utility model discloses an adjustable-length stainless steel fastener, comprising: a column 1, a column 2 below the column 1, a column 3 below the column 2, a thread 4 on the side surface of the column 3, a slot 9 on both the column 1 and the column 2, a locking post 10 engaging within the slot 9, a locking plate 13 fixedly connected to the lower surface of the locking post 10, the locking plate 13 being fixedly connected to the upper surfaces of the column 2 and the column 3, fixing holes 5 on both the column 1 and the column 2, and a through hole 11 on the locking post 10. A fixing post 6 is provided inside the 5. The fixing post 6 passes through the through hole 11 and extends into the fixing hole 5 on the other side of the locking post 10. A fixing block 7 is fixedly connected to the upper surface of the first column 1. A screw head 8 is fixedly connected to the upper surface of the fixing block 7. Both the first column 1 and the second column 2 are provided with grooves 12. The locking plate 13 is located in the grooves 12. Both the first column 1 and the second column 2 are provided with slots 14. A locking block 15 is engaged in the slots 14. The locking block 15 is fixedly connected to the upper surface of the locking plate 13. There are four locking blocks 15, which are distributed in a ring around the axis of the locking plate 13.

[0021] Specifically, if column 2 is not needed, insert the locking post 10 on column 3 into the locking slot 9 on column 1, and align the locking block 15 with the locking slot 14. Since the locking post 10 is square, and under the action of the locking block 15 and the locking slot 14, radial rotation can be prevented. Then insert the fixing post 6 into the fixing hole 5, and pass it through the through hole 11 on the locking post 10 to lock and fix the locking post 10. It can then be used. If column 2 needs to be added, first remove column 3, then install column 2, and then install column 3. The fixing block 7 and the screw head 8 make it easy to screw column 1, so that its tightness is better.

[0022] Working principle: When using, first insert the locking post 10 on column 3 into the locking slot 9 on column 1, and let the locking block 15 be inserted into the locking slot 14, so that the locking plate 13 enters the groove 12 to complete the locking. At the same time, insert the fixing post 6 into the fixing hole 5, and let the fixing post 6 pass through the through hole 11 on the locking post 10 to complete the locking and fixing. If the length needs to be extended, use the same principle to first remove column 3, and then install several columns 2 as needed. After installation, install column 3 again.

[0023] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
