Description

Improved Fasteners (2)

This creation involves the improvement of the construction of fasteners (also known as turnbuckles, or Turnbuckles).

A fastener 80, as shown in Figure 6, is used in a binding operation. Said fastener 80 is composed of a ring body 81 and two tension members 86 . Two connecting parts 82 with the same shape and opposite directions are connected together by two arms 84 to form a hollow ring body 81 , and the hollow part of the ring body 81 is defined as a hollow part 85 . Each coupling portion 82 forms an inner screw hole 83 which can be connected to an outer thread segment 88 of the corresponding tension member 86 in the helical direction. The external thread segment 88 is designed in one piece with a binding portion 87 to form the tensioning element 86 .

A tool (not pictured) is rod-shaped, one of the two ends is inserted into the hollow part 85, and resists the two arms 84, and the other end receives external force, so that the tool drives the ring body 81 relative to the two tension members according to the lever principle 86 spins. The screw connection between the inner screw hole 83 and the outer thread segment 88 converts the torque of the ring body 81 into the displacement of the tying portion 87 along the length of the fastener 80, and pulls the rope, rope or chain for binding articles. tightening, or loosening.

The material of the ring body 81 is mostly made of zinc, aluminum or its alloy, which is not only expensive to manufacture, but also has poor structural strength by die casting, which relatively shortens the service life of the fastener 80 .

In order to solve the above-mentioned problems, the US Patent No. 5,908,261 uses the Elongate Fibers to add fibers into the support arm, and then uses the method of casting liquid injection molding to strengthen the structural strength of the ring body.

In addition, the Taiwan Certificate No. I305161 patent case chooses the punching mode and first makes a pipe. Two force-applying holes are formed on both sides of the pipe, and the pipe walls on both sides of each force-applying hole are bent inward to form two folded edges, thereby forming two hollow support arms.

However, the overall structure of the fasteners (namely Turnbuckles) of the two patents has not yet broken away from the existing rut, and relies on tools (not shown) to be inserted into the ring body, which still has the disadvantage of poor structural strength and relatively shortened service life of the fasteners.

Therefore, how to smoothly operate the fasteners to perform the tightening operation has become an urgent issue to be solved in this creation.

In view of this, one of the main purposes of the author's improved fasteners in this case is to adopt a closed structure to improve the drawbacks of hollow holes in conventional objects, and to increase the wall thickness to improve the structural strength.

One of the main purposes of this creation is to abandon the existing rut of fasteners and use clamping tools instead to extend the service life relatively.

In order to achieve the above purpose, the fastener of the present invention includes: a pipe, two inner threaded holes are opposite to each other across an inner space of the pipe, each of the inner threaded holes is surrounded by a thick wall, the said The inner space of the pipe is surrounded by a thin wall, and the two ends of the thin wall are respectively connected with the thick wall; and the two outer thread segments are respectively locked into the corresponding inner thread holes.

In this way, in the fastener of this creation, the inner space of the pipe fitting is closed by means of thin wall and thick wall, so as to improve the disadvantages of hollow holes in conventional objects and improve the structural strength. Moreover, the inner space of the tube enclosed by the thin wall is a polygonal section, which can not only block the pollution of dust, but also extend the service life with the fixture.

In order to make the purpose, features and advantages of the present creation easy to understand, one or more preferred embodiments are presented and described in detail as follows in conjunction with the accompanying drawings.

Next, the embodiments of the present application will be described with reference to the accompanying drawings. In the drawings, the same or similar structures or elements are denoted by the same reference numerals. It is foreseeable that the described embodiments are only some examples of the present application, not all of the embodiments. Other embodiments that can be obtained by deduction based on the described examples, or modified or changed structures as needed, all fall within the scope of protection of this case.

In the following description, directional terms such as "up", "down", "left", "right", "front", "rear", "inner", "outer" and "side" refer only to the directions of the drawings. . The use of directional terms is for better and clearer description and understanding of the present case, and does not indicate or imply that the devices or elements described must have specific orientations, structures and operations, and therefore cannot be construed as limitations on the technical content of the present case.

Unless there are specific and clear specifications and limitations, in the following description, "installed", "connected", "connected" or "disposed on" should be understood in a broad sense, such as fixed connection, detachable connection, integral connection, mechanical connection , directly connected, indirectly connected, or connected between two elements. For those skilled in the art of the present application, with common knowledge or experience, they can understand the specific meanings of the above terms in various embodiments and even in the present application.

In the following description, "plurality" means two or more, unless otherwise specified.

As shown in Figures 1 , 2 and 3 , a preferred embodiment of the present invention discloses: a pipe member 11 , two first tension members 20 and two second tension members 30 . Combine as a fastener 10 by one of the following options:

a) The two ends of the pipe piece 11 are respectively combined with the first tension piece 20;

b) The two ends of the pipe piece 11 are respectively combined with the second tensioning piece 30;

c) One end of the pipe member 11 is combined with the first tension member 20 , and the other end is combined with the second tension member 30 .

Viewed from the internal structure, the pipe fitting 11 has two internally threaded holes 13, which are opposite to each other across a pipe inner space 16; or, the pipe inner space 16 connects the two internally threaded holes 13 together. Wherein, each of the inner threaded holes 13 is surrounded by a thick wall 14 , and the inner space 16 of the tube is surrounded by a thin wall 17 . Therefore, the two ends of the thin wall 17 are connected to the thick wall 14 respectively.

In terms of external contour, the outer surface of the thick wall 14 is a convex curved surface, and the convex curved surface is connected head-to-tail in the circumferential direction, so the convex curved surface is also called a circumferential surface, so that the thick wall 14 is like a connecting section 12 of a circular tube. The outer surface of the thin wall 17 is connected by two flat surfaces 18 to two convex curved surfaces 19 with the same curvature and opposite directions, which together form a polygonal segment 15 similar to an ellipse. The two ends of the polygonal segment 15 extend to the root of the connecting segment 12 in a constricted and reduced manner, respectively.

In this embodiment, the first tension member 20 and the second tension member 30 are metal objects. Wherein, one end of the first tension member 20 is formed with a hook-like binding portion 22 , and the other end is turned with an external thread section 24 . One end of the second tension member 30 is a ring-like binding portion 32 , and the other end is also an external thread segment 34 .

When assembled, the external thread segment 24 of the first tensioning member 20 or the external threading segment 34 of the second tensioning member 30 is locked into the corresponding internal thread hole 13 according to the helical direction to form the fastener 10 .

In use, the tie portion 22 of the first tension member 20 is connected to a fixture (not shown), or a rope, rope or chain (not shown) for binding objects. The tie portion 32 of the second tension member 30 is connected to one of a cord, cord and chain, or a fixture. Selecting a suitable tool around, a user applies torque to the polygonal segment 15 to drive the tubular member 11 to rotate relative to the first and second tension members 20 and 30 . The tool can be an open-end wrench, adjustable wrench, pipe wrench or other fixtures, etc., to clamp the two flat surfaces 18 on the opposite sides of the fastener 10 .

Under the condition that the inner thread holes 13 are screwed with the outer thread segments 24 and 34, the first tensioning member 20 and the second tensioning member 30 are close to each other, so that the rope, rope or chain is fastened. Alternatively, the first tension member 20 is separated from the second tension member 30, and the rope, rope or chain can be loosened so that the article can be taken out.

In Figure 4, no tensioning elements are screwed in anymore. Instead, the pipe fitting 11 is combined with two bolts 40 to form the fastener 10 together. Each bolt 40 has a head 42 and an externally threaded section 44 that locks into the corresponding internally threaded hole 13, supporting the head 42 as the exposed end of the fastener 10 (or bolt 40). Here, the head 42 is hexagonal.

The difference is that the aforementioned tensioning member generates a pulling force, which gives the fastener 10 a tensioning rope, rope or chain to produce a tightening effect of binding the article. The bolt 40 uses a thrust force to give the fastener 10 to push the object against the wall or other fixed objects, and also achieve the purpose of fastening.

As shown in Fig. 5, the pipe 11 changes the outer contour. In short, without a convex surface, the polygonal segment 15 has six connected planes 18 to resemble a hexagon. By using a tool such as an open-end wrench, adjustable wrench, pipe wrench and clamp, to clamp the two flat surfaces 18 on two sides or opposite sides of the polygonal segment 15, the pipe fitting 11 can be twisted to drive the bolt 40 to move.

To sum up, the fasteners of this creation have the following advantages:

First, the thin wall is matched with the thick wall to construct a closed internal space, which prevents the external dust from contaminating the internal structure of the fastener, thereby improving the structural strength.

Second, the thin wall encloses the inner space of the polygonal segment, so that the overall structure of the fastener can be separated from the existing rut, abandon the rod-shaped tool, and use the clamping tool to twist the pipe fitting, which relatively prolongs the service life.

Those skilled in the art can understand and make changes to the above-mentioned embodiments without departing from the broad concept of the present case. Therefore, this case is not limited to the specific embodiments disclosed in the specification, and any modifications made according to the spirit and technical scope of this case should be covered and protected by the text content defined in the scope of the patent application.
