面内にくるように設ける。[Prior Art and Problems to be Solved] Conventional turnbuckles are rotated using a spanner, lever, etc. in a plane perpendicular to the longitudinal direction of the female thread of the main body. Therefore, unless there is a wide space in the direction perpendicular to the axis of the turnbuckle, tension tightening cannot be achieved by continuous rotation, resulting in intermittent reciprocating operation, which requires labor and time. Furthermore, since the direction of the force is perpendicular to the axis of the turnbuckle, the wires hooked to the left and right joints swing and become unstable, making it difficult to apply sufficient force and making work difficult. 1. Means for Solving the Problems] The present invention is a novel turnbuckle that solves the above-mentioned problems, and the gist of its configuration is that it has a right-handed threaded joint (2) and a left-hand threaded joint (2) at both ends. 3) a main body female threaded pipe (1) having a right female threaded portion (4) and a left female threaded portion (5) that are screwed in, and a worm gear (6) fixed at the center;
A casing (10) of the worm gear (6) rotatably fixed in position with respect to the main body female threaded pipe (1,), and a main body female threaded pipe (1) fixed to the casing (10). a bearing casing (14) having a shaft (13) perpendicular to the shaft (13); a worm (15) and a ratchet wheel (16) that mesh with the worm gear (6) provided with respect to the shaft (13); It has a latch claw (17) provided on the outer periphery of the wheel (16). The turnbuckle consists of an operating lever (18) that rotates in a plane that includes the axis of the female threaded pipe (1) of the main body. In addition to the above configuration, a handle (19) is provided on the opposite side of the ratchet wheel (16) of the bearing casing (14), and the vicinity of the tip of the operating lever (18) is approximately within the axial plane of the female threaded pipe (1) of the main body.

極めて有用なターンバックルである。Using a worm and a worm gear, the rotating direction of the operating lever (18) is made substantially within the axial plane of the main body female threaded pipe (1), facilitating tightening work in a narrow space. By changing these rotation ratios, you can adjust the weight and weight of the force. It also prevents backward movement and allows for stable work since the direction of rotation is approximately in the same plane as the direction of tension. The carrying handle (19) is convenient for transportation and also serves as a grip when rotating the operating lever. Example 1 The present invention will be explained in more detail below with reference to the drawings. FIG. 1 is a side view, and FIG. 2 is a plan view. In these figures, the body female threaded pipe (1) has right-hand threaded fittings (2) at both ends.
A right-hand female threaded portion (4) and a left-hand female threaded portion (5) into which the left-hand threaded joint (3) is screwed are provided, and the worm gear (
6) is a sturdy thick steel pipe. In this case, the right-hand threaded joint (2) and the left-hand threaded joint (3) have bifurcated ends and the bolt pin (7) is inserted through them, but they may also be simple hooks. Furthermore, the bolts (8) and washers (9) are used to prevent loosening after tightening to further improve safety. A worm gear (6) is installed approximately in the center of this main body female threaded pipe (1) so that the casing (10) of the worm gear (6) can rotate coaxially with the main body female threaded pipe (1) and is fixed in position. ) with two collars (11) that touch lightly on both sides of (
11) and a short tube (12). and. A bearing casing (14) having an axis (13) perpendicular to the longitudinal direction of the main body female threaded pipe (1) is fixed to the casing (lG), and the worm gear (6) is attached to this axis (13). ) which engages with the worm and ratchet wheel (16). The outer periphery of the ratchet wheel (16) has a latch pawl (17), and the female threaded pipe (1) of the main body has a latch pawl (17).
An operating lever (18) is provided that rotates within a plane that includes the axis of. Furthermore, in addition to the above configuration, a handle (19) is provided on the opposite side of the ratchet wheel (16) of the bearing casing (14). The turnbuckle of the present invention is operated as follows. Between the materials to be tightened, hook a wire rope with a hook or a steel rod with a hook to the bolt pins (7) (7) on both sides, and tighten the bolts (
8) Keep (8) sufficiently loosened and hold the turnbuckle. Next, in FIG. 1, the operating lever (18) is reciprocated approximately 180° left and right to connect the left and right threaded joint (3) (
2) into the center of the main body female threaded pipe (1). Effect of the Invention 1 As mentioned in the section of operation, this operation is performed when the operation lever (18) is connected to the main body female threaded pipe (1
), the tightening work in narrow spaces becomes extremely quick and easy. The direction in which the operating lever (18) is moved is also in the same plane as the tensioning direction, which has the effect of allowing stable work without twisting or lateral vibration. In particular, this turnbuckle is extremely useful for use in reinforcing and correcting beams when laying the exterior panels of ships, securing large containers, etc.
