Handle buckle

Abstract

A handle buckle (C) is composed of a main body part component (P1) and a back surface member (P2). As the installation of the spring mechanism (3), the front surface of the back surface member (P2) and the rear surface of the hook rod (2) are provided with grooves (106,206) with a generally arc-shaped cross section; the spring mechanism (3) is composed of a pair of spiral spring supporting components (31) and a spiral spring (32), wherein the pair of spiral spring supporting components (31) are formed in a substantially semi-cylindrical shape and are arranged in the groove (106,206) to be capable of being poured and made of a synthetic resin material; the two ends of the spiral spring (32) are clamped on the spiral spring supporting components (31) so as to enable the spiral spring (32) tobe compressed and arranged between the back surface member (P2) and the hook rod (2).

Description

technical field [0001] The present invention relates to a handle buckle (locking device), which is used for fixing box-shaped cargo boxes (Japanese: box-shaped の荷台) (aluminum container ) or the door opening and closing of a container for transportation, etc., is restricted and locked with a door switch handle. Background technique [0002] Generally, the door of this kind of container is of a split type. When locking the door, the following method is adopted: the lock shaft is rotated with the handle of the door switch, so that the lock heads (Japanese: lockcam) at the upper and lower ends of the lock shaft are aligned with the side of the container. The lock seat (Japanese: カムキーパー) is engaged to keep the door locked. In addition, the above-mentioned door switch handle is restricted by a handle buckle (lock device) installed on the door, and the lock unit (Japanese: ingot front ユニット) installed on the above-mentioned handle buckle is locked by a key, thereby locking the abov...

Problems solved by technology

[0014] (1) if Figure 12 As shown, the main body 6 is composed of a front part 601, a back part 602, two side parts 603 and a bottom part 604. There is a handle crossing the support part 61 between the upper part of the front part 601 and the upper part of the back part 602, and there is a handle from the front part. The upper center of 601 is cut in a substantially U-shape in the vertical direction, and the lever housing portion 62 has a shape required for arranging the spring mechanism 8A, the lock lever 92, and the lock cylinder 9 inside, so the overall structure is complicated. , and the production cost and maintenance cost of the mold used to form the main body increase, and at the same time, it takes a lot of time to make the mold

[0015] (2) if Figure 13 As shown, since the spring mechanism 8A is composed of a pin 81, a spring support plate 82, a guide plate 83, and a coil spring 84, wherein the above-mentioned pin 81 is arranged on the back side of the hook lever 7 in the horizontal direction, and the above-mentioned spring support plate 82 has a back side The fixing part 821, the pair of intermediate arms 822, the front side fixing part 823, and the spring support part 824. The above-mentioned coil spring 84 is compressed by passing through the above-mentioned guide plate 83 and arranged on the spring support part 824 of the pin 81 and the spring support plate 82. Therefore, the number of parts is large, the structure is complicated, and the cost increases
