Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a screwing mechanism with a screw stud, a method for manufacturing the same, and a turnbuckle using this mechanism.

When the screw rod in the screw-shaped lug is removed from the screw-attached body part of this screw stud and screwed into it, or the screw-attached body part is moved using the screw stud in a fixed state as a guide. When the amount of movement is large, whether the twisting rod is rotated or the screwed body part is rotated fully, it takes a lot of effort and a long time, and there remains a big problem in terms of work efficiency.

When the screw rod or the screwed body part is moved from place to place, this invention temporarily releases the threaded state between the screw rod and the screwed body part, and after the completion of the large-scale movement work, the threaded rod and the screwed body part are removed. The screwing mechanism with the screw shaft of this invention reproduces the solid screwing state with the screw shaft, and the subsequent fine adjustment of the movement width is realized by the original rotational screwing. A concave arcuate surface is formed on the lower surface of the main body having a shape of a groove, and a pressing block which can be lowered in the direction at the bottom of the groove of the main body is housed with its side wall in sliding contact with the inner wall surface of the main body. , insert a tension rod into the U-shaped main body, and write ml on at least one surface of the groove bottom surface of the U-shaped main body that faces the screw stud and the concave arc surface of the suppressing block. Structure J formed by forming a threaded surface that engages with the rod: By temporarily separating the pressing block from the threaded rod, the screwed state of the screwing rod and the screwed body part is released, and the position is corrected. The present invention is intended to speed up and simplify movement.Next, specific embodiments of the present invention will be described with reference to the drawings. In the figure, (1) is a main body made of a long piece of steel plate bent into a U-shape and provided with a U-shaped groove, and the bottom surface of the semi-circular main body is made to match the threaded pinch of the corresponding threaded rod 03. A semicircular threaded surface (3) is formed. The upper opening of the main body is closed with a cover plate (4), and the screw shaft (6) of a bolt (5) screwed in from above the cover plate (4) protrudes through the step (7) at the tip. A suppressing block (9) is rotatably attached to the provided small diameter shaft (8) by caulking means at the end of the small diameter shaft (8) so as to be rotatable about the small diameter portion (8).

The lower surface of the block (9) is formed with a concave arc surface that matches the thread surface of the corresponding threaded rod α1, and the block (9)
The side walls of the U-shaped main body (1) are a pair of opposite walls (2) (2
), and in response to the rotation of the bolt (5), the suppression glock (9) built into the main body (1) moves into the U-shaped groove of the main body with a constant stroke in a non-rotating state. Money goes up and down. The threaded rod 03 is inserted into the screw-attached body part (lυ) having the above structure, and the approximately lower half of the screw thread αQ is screwed into the semi-annular threaded surface (3) provided at the inner bottom of the main body (1). When the lower half of the screw holder 03 is pressed against the concave arc surface 4 of the pressing glock (9), the screw holder α] is strongly held between the inner bottom of the U-shaped body and the pressing block. Ru.

As the bolt (5) rotates, the suppressing block (9) rises, and a gap is generated above the screw shaft α4 inserted into the screwed body part αυ, and the screwed body part 0υ and the threaded rod The threaded state of is released, and the threaded rod α■ protrudes from the threaded main body in the fixed state and moves freely and quickly, and on the contrary, the thread along the threaded stud Q3 in the fixed state is released. The screwed body part 0υ can be moved freely and quickly in the front and rear directions using a rod as a guide, and the screw thread 01 or the screwed body part aυ that has been moved approximately to a predetermined position or a predetermined width can be moved freely and quickly. Then, as the bolt (5) rotates, the suppressing block (9) is lowered into the U-shaped groove of the main body, and the screwing and fixing with the main body part qυ of the threaded rod 4 is completely reproduced. After that, slight adjustment of the movement width is achieved by rotating the original threaded rod or the screwed body part. In addition, a threaded rod corresponding to the concave arc surface 01 of the pressing block (9) (with a metal engraving on the threaded surface matching the screw pinch of 13), the upper and lower surfaces of the threaded rod are clamped by the threaded surfaces, and the screwed body is A structure that can increase the screwing strength between the part and the draw rod, and also provides a threaded surface that matches the thread pitch of the draw rod that corresponds only to the concave arc surface LlO of the pressing block (9). This also suppresses the noise generated during the extraction work from the threaded main part of the screw stud, and makes the extraction work even smoother.
) of the main body (1) of the block (9), J: In order to prevent the main body from coming off, abutment plates for closing the upper part between the opposing walls (2) of the main body (1) are provided at both rear ends of the main body (Fig. 3, Fig. 4) It has a great effect on ensuring safety, and especially when a threaded surface is carved only on the concave arc surface of the suppressing Glock, it completely improves the safety, which is preferable. You can expect good results. If necessary, tighten the bolt strongly with a spanner instead of a spanner on the head of the bolt (5)! A through hole uO is provided for inserting a tightening rod which can be used at one time.

In this invention, the screw-attached body part of the push rod,! :! lll
When it is necessary to significantly protrude or retract the screwed body part, or to move the screwed body part forward or backward along the tensioning rod, the entire threading process can be omitted, and the tensioning rod and the screwed body part can be temporarily moved. The threaded state with the threaded part is released, and a large movement is completed with the threaded part in a non-meshing state.The subsequent lowering and clamping work of the suppressing block reproduces the previous threaded state 11', and a small amount of Since only the moving work can be performed by conventional screwing work, this invention greatly contributes to speeding up and simplifying the screwing work, and since this invention has a simple structure, there are fewer failures, and it provides a product that is inexpensive in terms of cost. It is something that greatly contributes to.

Next, we will move on to a description of the second invention, a method of manufacturing a screwing mechanism with a threaded rod. In this manufacturing method, a long piece of steel plate is placed on a lower mold with a U-shaped groove, and a downwardly protruding piece with a semi-annular thread carved at the tip is provided in the center of the long piece. A process of positioning the protruding strip of the upper mold, bringing the protruding strip into the U-shaped groove of the lower mold, fully press-welding both molds, and bending the long strip to form a U-shaped main body. , by synchronizing the process of carving a threaded surface on the bottom surface of the U-shaped groove of the main body, and forming a concave arcuate surface on the bottom surface of the shaft end of the bolt that is threaded toward the bottom surface of the cover plate, and threading the screw surface on the bottom surface. The upper opening of the U-shaped main body is closed by a cover plate on which a suppressing block 07 with or without a surface is rotatably mounted, and the side wall of the block is closed. The process consists of a process of building the body into the body so that it can slide along the inner wall surface of the body and move up and down, and a process of inserting a tension rod between the U-shaped bottom of the body and the suppression/slock space. This method is intended to simplify the manufacturing process and shorten the working time. Next, a concrete example of this manufacturing method will be described with reference to the drawings.

A long piece of steel plate is placed on the lower mold (21), which has a U-shaped groove (A) on its surface, and above the lower mold (21), the lower mold ■υ Corresponding to the U-shaped groove (A), this U-shaped groove (A)
When fitted into the groove (A), the downward protruding strip (C) is raised while maintaining an I-Ml gap approximately corresponding to the wall thickness of the long piece (1a), and An upper mold (A) with a threaded surface (C) is placed on the semi-circular tip surface of the protruding strip (C), and the upper mold is lowered to release the downward protruding strip (C). In c), the central part of the long piece Qa) is folded in two to form the U-shaped main body (1) in end view, and at the same time, the U-shaped groove of the lower mold Qυ (
B) Due to strong pressure from the protruding strip of the upper mold that has been fitted and lowered into the groove, the protruding strip (
A semicircular thread surface (3) is carved corresponding to the semicircular arc thread surface (c) of (c). A threaded hole bored in the center of a thick lid plate (4) that closes the upper opening of the U-shaped main body (1) has a step (7) at the front of the threaded shaft (6). Through this, the bolt (5), which has a small diameter part (8) with a concave part C14) recessed in the center of the end face, is screwed into the cover plate (4).
) At the tip of the bolt protruding from the bottom surface, there is a suppression block (9) with a concave arcuate surface ACS' formed on the bottom surface, and a small diameter portion (8) at the tip of the bolt is inserted into the mounting hole drilled in the center of the suppression block (9).
J: 9, small diameter part (8 ) is rotatably attached to the shaft.

The lid plate (4) attached to the suppressing block (9) in a suspended manner closes the upper open part of the main body (1) and reinforces the open part.
All the means such as welding are used to fix the screws, while the pressing plow (9) has both sides attached to the pair of opposing walls (1) of the main body (1).
2) Built-in in sliding contact with (2). Note that the concave arcuate surface σO of the block (9) may be provided with a metal engraving on the threaded surface that matches the threaded portion of the corresponding threaded stud Q3.

In the above structure, r, the threaded body part 0υ is a bolt (5
) is completed by inserting the threaded rod 03 into the gap that has expanded between the suppression pulley (9) that has risen and the inner bottom surface of the U-shaped body (1). As the pressing block descends as the bolt rotates in the opposite direction, it is screwed into the J:9 threaded rod by the screw clamp between the bottom surface of the U-shaped body of the screw stopper and the concave arc surface of the pressing block. The mechanism becomes reality.

In the manufacturing method of this second invention, a long piece of steel plate (l
During the bending process to form the U-shaped main body in a), the threaded surface corresponding to the threaded rod is carved on the bottom surface of the main body at the same time, so manufacturing efficiency can be increased, and the bolt tip When attaching to the suppression block, the bolt tip is opened outward by making use of the relatively thin part created by recessing the center of the small-diameter end face of the bolt tip. This makes V7 clamping and work easier, and work efficiency can be completely improved in this aspect as well.

Next, as a third invention, a turnbuckle that fully utilizes the screwing mechanism with the screw shaft, which is the first invention, will be explained.

A conventional turnbuckle allows a wire rope with a turnbuckle interposed as a result of the rotation of the frame into which the twisting rod is screwed, and the extension and shortening of the telescopic body assembled by the V-twisting rod and the frame. It is intended for tension and relaxation of wire robes, chenos, etc., but if the turnbuckle needs to be significantly extended or shortened, the number of rotations of the frame will inevitably increase, making it difficult to tension and relax wire robes, chenos, etc. The work required a great deal of effort, and this was a major factor in reducing work efficiency. This invention utilizes the above-mentioned screwing mechanism with the shaft in a permanently essential component of the turnbuckle. This invention aims to speed up and simplify the work by significantly moving the screw thread or the frame and reproducing the screwed state after that.Next, specific embodiments of this invention will be explained with reference to the drawings and sounds. .

The main body is made of a long piece of steel plate bent into a U-shape and provided with a U-shaped groove (
A semi-annular threaded surface (3) is formed on the bottom surface of the semi-annular main body (1) to match the threaded pinch of the corresponding screw thread. The upper opening of the main body is closed with a cover plate (4), and above the cover plate (4)! A suppressing block (9) is attached to the small diameter shaft (8) that protrudes through the step (7) at the tip of the threaded shaft (6) of the screwed bolt (5). The ends are crimped to allow rotation i+J around the small diameter portion (8). The lower surface of the block (9) is formed with a concave arcuate surface that matches the thread surface of the corresponding screw thread, and both side walls of the block (9) are formed with a pair of U-shaped bodies (1) and (7) facing each other. In sliding contact with the inner surface of the wall (2) (2), the suppression glock (9) built into the main body (1) moves with a constant stroke in a non-rotating state according to the rotation of the bolt (5). Go up and down inside the groove. The screw thread is inserted into the screw main body part 01) having the above structure, and the approximately F half of the thread thread is screwed into the semi-annular thread surface (3) provided at the inner bottom of the main body (1). At the same time, the lowered concave arcuate surface uO of the suppressing block (9) comes into pressure contact with the road half of the screw stud 03, and the screw stud Q3 is held between the inner bottom of the U-shaped main body and the suppressing block.

The screwing mechanism for the screwing body part 01) and the threading rod constituted by the screw stud 04 is attached to the end of the frame 6υ constituting the turnbuckle. As this frame, a wide variety of hollow long paulownia pieces such as large-diameter pipes and channel-shaped materials can be used, but as shown in the figure, two long paulownia pieces 6 are used and one end is screwed. Main body (1)'f of the attached body part 0υ: fixed to the outer surface of the constituent opposing walls (2) (2) by means such as welding, and an engaging member trowel is rotatably disposed at the bolted end, The turnbuckle (c) is also completed by fixing the engaging portion paulownia lining to the outer end of the screw thread.

In addition, a threaded surface that matches the thread pitch of the threaded rod α that corresponds to the concave arcuate surface QO of the suppressing block (9) is carved, and the threaded surfaces are engaged on both the upper and lower surfaces of the threaded rod to ensure screwing. The screwing strength between the biological part 0υ and the screw thread θ■ can be completely increased, and only the concave arc surface of the pressing block (9) is carved with a threaded surface that matches the thread pitch of the draw rod. However, it can also be used as a turnbuckle for light loads.

In the turnbuckle according to the present invention, the elastic body composed of a screw stud and a frame body can be adjusted according to the tension of wire ropes, etc., which are connected using engaging members disposed at both ends of the turnbuckle. It is necessary to adjust the length and tone of
At this time, as the bolt rotates, the suppressing block is raised within the main body, instantly releasing the threaded lock between the screwed body part and the screw rod, and allowing the screw rod to freely and quickly release the frame body. After performing all the extraction and retraction operations, the suppression block is lowered to reproduce the screwed state of the screwing rod and the screwed body part, and then the delicate extension and contraction adjustment of the turnbuckle is made by rotating the frame a small number of times. Since this purpose can be achieved, tension and relaxation work on wire ropes, etc. can be done quickly and easily, and this speed can be further improved by simplifying the lifting and lowering operation of the pressing block. It will be done. In addition, by forming the frame that constitutes the pattern buckle with two long bars, it greatly contributes to reducing the cost of the product. By forming the entire main body, the turnbuckle frame and the screwed body part can be connected and assembled very easily and toughness can be ensured.
