Description

Locking device and wire tightener integrally formed with the same

The present invention relates to a retaining member, and more particularly to a simple retaining member for preventing looseness of a container tensioner. Background technique

The wire tightener typically includes a sleeve-like intermediate body having opposite internal threads on its opposite ends, and two screws that are each threadedly coupled to the intermediate body. When a wire tightener is used to secure the container to the deck of the ship, the tightener is often subject to vibrations from the engine of the ship or other forces caused by wave fluctuations, which inevitably become loose and continue to loosen even after tightening. . Therefore, personnel must always check and tighten the tightener again to ensure that the container on the deck can be fixed in position. However, this method of operation is not only time-consuming, but also dangerous for those who perform work when the wind is heavy.

U.S. Patent No. 3,806,265, the entire disclosure of which is incorporated herein by reference to U.S. Pat. The stop opening is sleeved on the rotating screw of the tightener. However, since the locking band is made of nylon, its strength is obviously unable to withstand the force exerted by the container, and it cannot overcome the looseness of the tightener. At the same time, due to the harsh weather at sea, the holding power of nylon is inevitable. It quickly deteriorated, so the case could not be used.

U.S. Patent No. 5,156,482, issued to Owings, et al., which is incorporated herein by reference. However, since the locking plate is disposed at the end of the screw, the locking plate must also pass through the screw hole of the body, which increases the difficulty in operation, and at the same time, the gap between the locking plate and the body slot is large, and the actual In the operation, the locking plate does not appear to be stuck at the edge of the body slot. Therefore, the locking plate may be loosened, and similarly, the locking function is lost.

A container knotter disclosed in Chinese Patent Publication No. 1689924A is provided with a limit seat slidably mounted in the body of the tightener and engaged with the end of the screw. Since the limiting seat is engaged with the end of the screw, the screw hole in the tightener must be accurately formed on the central axis of the tensioner body, and any small error causes the limiting seat to be incapable of meshing with the screw, so that The case cannot work. Moreover, since most containers use a tightener, in use, a screw having a top-bottom relationship, when the limit seat is placed under the screw, it is easy to loose and fall from the tightener, especially when the vessel Sailing on the raging sea.

U.S. Publication No. 2007/0116510, issued May 24, 2007, discloses a tightener lock, which includes A plate is directly attached to the wire tightener, the plate is provided with a slot for the pin on the screw to pass through, and the two connecting holes are provided for

The U-bolt is fixed to the wire tensioner body. However, in fact, most of the screws do not have this pin for fixing. Therefore, the case cannot be applied to all the tightener devices. At the same time, the operation must lock the plate and the u-type bolt on the tightener. This has obviously increased the loading and unloading of containers for a considerable period of time. Therefore, the case has its limitations in terms of use and practical operation. Summary of the invention

Before the details of the present invention are described in detail, it should be understood that all the same like components are represented by the same reference numerals throughout the drawings.

Referring to Figure 1, there is shown a retaining member 10 in accordance with a first embodiment of the present invention for securing a conventional tensioner 100. The conventional tightener 100 is generally composed of three main components, namely, a long hollow body 120, and two screws 140 (only one shown in the figure) screwed in opposite directions to the opposite ends of the hollow body 120, so that the body 120 When rotated, the axial distance between the screws 140 can be adjusted. The intermediate portions of the elongated body are each defined with a longitudinal opening. The head of the screw is not shown in Fig. 1. There are currently a large number of eyebolt type, hook type, and Gaw type joints to use various joints depending on the connection requirements. . Further, as shown in Fig. 1, a hexagonal head 160 is integrally formed at the end of the body 120, however, in practice, the end portion may be circular or elliptical.

The locking member 10 of the present invention comprises a U-shaped stop block 20 and a clamping rod 80. The stop block 20 is configured to be sleeved on the screw 140 when in use and has a circular arc engaging surface 24 for engaging the threads on the screw 140. In addition, a cover portion 26 is provided with a circular arc engaging surface 28 disposed diametrically opposite the engaging surface 24 for engaging the threads on the screw 140. Although the mating surface is shown as a threaded surface, it may also be, for example, a threaded tab (not shown) for snapping onto the threads of the screw 140. Although, Fig. 1 shows a threaded surface having two arcs, of course _, if the meshing strength permits, only one side of the threaded surface may be provided. For example, only the mating faces 24 or 28 are threaded and the other is not threaded. The stop block 20 further includes a mounting portion 30 defining a longitudinally extending section 32 and a laterally extending section 34 for mounting against a plane of the hollow body 120 or the hex head 160.

The clamping rod 80 has a cam clamping end 82 and a clamping arm 84 extending from the clamping end, and is pivotally connected to the end of the stopping block 20 via a pin 40 and disposed above the cover portion 26 .

2A and 2B show that the locking member 10 of the present invention has been coupled to the tensioner 100. Therein, the cam clamping end 82 of the clamping lever 80 has a cam surface 86 that cooperates with the upper pin 40 to establish a cam mechanism. The cam surface 86 functions to urge the engagement faces 24, 28 of the stop block 20 when the clamping lever 80 is pivoted from a vertical position (as shown in Figure 2A) to a horizontal position (as shown in Figure 2B). Engaged on the threads of the screw 140 while the longitudinal extension 32 of the mounting portion abuts against a plane of the hex head 160. The cam action is increased by the pressure between the stop block 20 and the cover portion 26, thereby preventing the tensioner body 120 and the screw 140 from rotating relative to each other due to looseness. Referring to Figure 3, there is shown a retaining member in accordance with a second embodiment of the present invention. Similar to the first embodiment, the locking member includes a U-shaped stop block 20' having another U-shaped lateral extension 34' for mounting at the edge of the tensioner 100. An engagement surface 24' is defined in the stop block 20'.

The clamping lever 80 is also constituted by the cam clamping end 82 and the clamping arm 84, except that there is no cover in this embodiment. Similarly, the clamping lever 80 is pivotally coupled to the end of the U-shaped stop block 20' via the pin 40. As shown in Fig. 4, when the fixing member of the present embodiment is fixed to the body 120 of the tensioner, it is also possible to prevent relative rotation of the body and the screw 140 due to looseness.

Figure 5 is a retaining member in accordance with a third embodiment of the present invention. Similar to the first embodiment, the locking member includes a U-shaped stopper 20, and is provided with an engaging surface 24 for inserting a gap between the body 120 and the screw 140 as shown in FIG.

Figure 7 is a partially exploded perspective view of the wire tightener 100'' integrally formed with the locking member 10' according to the present invention. The threader 100' includes a screw 140, which is a hook joint as shown. Of course, the other end of the wire tightener 100' may also have another screw 140 (not shown), for convenience only one single end will be described. The wire tightener 100' also includes a body 120', the end portion of which is provided with a screw hole 102 which is matched with the screw thread of the screw 140, and a U-shaped stopper block integrally formed with the thread of the screw, and a radial movable The cover portion 26 is provided with an engaging surface for engaging a thread fixed to the screw 140. As in the first embodiment, the locking member 10' is further provided with a clamping rod 80 pivotally connected to the end of the body via the pin 40' for engaging the engaging surface of the cover portion when pivoting the clamping arm The threads of the type stop block clamp the screw together.

In order to make the assembly quick and reliable, the end of the pin 40' of this embodiment is provided with a fixed locking claw 42, which allows the pin 40' to be locked after the insertion of the end of the stopper block. At the end of the moving block, as shown in Fig. 8, the pin 40' is fixed in position and is not easily peeled off.

Through the use of the locking member of the present invention, it can be directly used on the current fastener, and the purpose of the locking can be completed, and at the same time, it can be completed without any hindrance to the operation of the current fastener. At the same time, the locking member of the present case provides a clamping of the entire circumference of the screw, which not only provides the force of the locking, but also does not cause any damage to the thread itself. At the same time, if the pin with the fixed locking claw is matched, the assembly work can be completed quickly. Therefore, the development of the case is a great boon for the container transportation industry.
