A three-way restraint twist lock device

Abstract

The present invention relates to a three-way constraint twist lock device, comprising a locking shaft, three bases, a baffle, a pin, a handle, a latch, and an interface hole. The three bases are fixedly mounted at the top, middle, and bottom to serve as supports. The locking shaft is mounted on the middle and bottom bases, with the upper end connected to the handle via a joint and a pin. The handle is connected to the middle base via a latch, forming a lever structure, or the handle is connected to the upper base via a latch. The present invention can not only lock two vertically stacked objects, but also lock two objects moving relative to each other on a horizontal plane, thereby achieving horizontal and vertical locking of two objects moving relative to each other on a horizontal plane, as well as movement constraint in the front-to-back, left-to-right, and up-and-down directions.

Description

Technical Field

[0001] The present invention relates to a twist-lock device, in particular to a twist-lock device capable of restricting movement in three directions. Background Art

[0002] A twist lock device is a device that can constrain movement in three directions. It can not only lock two vertically stacked objects, but also lock two objects moving relative to each other on a horizontal plane. Currently, twist lock devices in the industry have the following problems:

[0003] (1) The container's twist lock can constrain the vertical direction, but the horizontal constraint gap is too large, causing slippage;

[0004] (2) Twist locks can only be used to lock two objects stacked vertically and cannot be used to lock two objects that are moving relative to each other on a horizontal plane. Summary of the Invention

[0005] The present invention aims to provide a three-way constraining twist-lock device that addresses the problems of existing twist-locks, such as large horizontal constraint gaps and an inability to lock two objects moving relative to each other on a horizontal plane. By configuring the twist-lock device, two objects moving relative to each other on a horizontal plane can be locked both horizontally and vertically, achieving motion restraint in the forward, backward, left, right, and up and down directions.

[0006] To achieve the above-mentioned purpose, the technical solution of the present invention is: a three-way constraint twist lock device, including a locking shaft, three bases, a baffle, a pin shaft, a handle, a latch, and an interface hole. The three bases are fixedly installed at the upper, middle and lower parts as supports. The locking shaft is installed on the two bases in the middle and lower parts. The upper end is connected to the handle through a joint and a pin shaft. The handle is connected to the base in the middle part through a latch to form a lever structure, or the handle is connected to the upper base through a latch.

[0007] Furthermore, the locking shaft is fixedly connected to the joint through a baffle.

[0008] Furthermore, the baffle is mounted on the joint by screws.

[0009] Furthermore, the locking shaft is connected with bushings installed in the two bases in the middle and lower parts by clearance fit.

[0010] Furthermore, when the twist lock device is used, the locking shaft is sunk into the interface hole by pulling up the handle, the pin is pulled out to release the handle from the middle base, the handle is rotated 90° in the horizontal direction, and then the handle is placed vertically upward in the upper base, and the pin is inserted to complete the operation of the twist lock device.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] (1) The present invention can not only lock two vertically stacked objects, but also lock two objects that move relative to each other on a horizontal plane.

[0013] (2) Through reasonable design, the present invention realizes the locking of two objects moving relative to each other on a horizontal plane in the horizontal and vertical directions, and realizes movement constraints in the front-back, left-right, and up-down directions.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] like Figures 1 to 6 As shown, an embodiment of the present invention provides a three-way constraint twist lock device, including a locking shaft 1, a base 1 2, a base 2 3, a bushing 4, a joint 5, a baffle 6, a pin 7, a handle 8, a latch 9, a base 3 10 and an interface hole 11. Base 1 2, base 2 3 and base 3 10 are all fixedly installed and serve as supports. The baffle 6 is mounted on the joint 5 by screws, and the locking shaft 1 is fixedly connected to the joint 5 through the baffle 6. The locking shaft 1 is loosely matched with the bushing 4 installed on base 1 2 and base 2 3. The handle 8 is hinged to the joint 5 through the pin 7 and is hinged to the base 2 3 through the latch 9 to form a lever structure.

[0024] like Figure 7 As shown, when the twist-lock device is in use, manually pulling handle 8 sinks locking shaft 1 into interface hole 11, locking objects that are moving relative to each other on a horizontal plane. Pulling out latch 9 releases handle 8 from base 2 3, rotating handle 8 90° horizontally, then placing handle 8 vertically upward into base 3 10 and inserting latch 9 completes the twist-lock device, locking two vertically stacked objects.
