Description

Technical Field

[0001] This invention relates to a bolting device, and more particularly to a multifunctional bolting device, belonging to the technical field of bolting devices. Background Technology

[0002] In various transportation sectors such as shipping and freight, tethering devices are needed to secure goods during transportation, movement, loading and unloading, or storage. Especially inside ships, a large number of tethering devices are needed, with one end fixed to the mooring seat of the elevator or transfer vehicle and the other end fixed to the fixed point of the goods to prevent the goods from tipping over or slipping off due to the ship's rolling during navigation.

[0003] Currently, the bolt tightening devices in the industry have the following problems:

[0004] (1) Due to the large amount of cargo transfer inside the ship, the tightening and loosening of the lashing device is required frequently. Sometimes, multiple lashing devices are needed for each piece of cargo. The existing lashing devices are mostly ratchet driven sleeves, which gradually loosen or tighten the lashing straps, resulting in a lot of time wastage during use.

[0005] (2) Existing fasteners and straps require manual recycling, which cannot achieve rapid recycling and wastes time during use.

[0006] (3) Existing fasteners cannot achieve multiple functions such as unidirectional elongation, unidirectional contraction, bidirectional elongation and contraction or locking of the webbing. They cannot be operated with one hand and have low ease of use. Summary of the Invention

[0007] The purpose of this invention is to provide a multifunctional cable tensioner and its usage method, solving the problems of low efficiency, limited functionality, and low convenience in the use of existing cable tensioners. By rationally distributing and nesting mechanisms such as a spring, ratchet, and ratchet lock within the cable tensioner, the invention achieves unidirectional extension, unidirectional contraction and tensioning, rapid retraction, free extension and retraction, and locking functions for the cable tie. The tensioning function is achieved through a crank handle and unidirectional contraction, thus improving the efficiency and ease of use of the cable tensioner.

[0008] To achieve the above objectives, the technical solution of the present invention is as follows: a multifunctional fastener, comprising a fork-type rotating hook, a binding strap, a fixing seat, a take-up reel riveting component, a spring assembly, a ratchet assembly, a switch assembly, and a crank handle. Two fork-type rotating hooks are respectively mounted on the binding strap, wherein one fork-type rotating hook is fixedly connected to the fixing seat via the binding strap, and the other fork-type rotating hook is connected to the take-up reel riveting component via the binding strap. The binding strap is mounted on the take-up reel riveting component and retracts with rotation. The take-up reel riveting component is connected to the spring assembly, the ratchet assembly, and the crank handle assembly and rotates synchronously. The switch assembly is mounted on the fixing seat and engages with the ratchet assembly.

[0009] Furthermore, the take-up reel riveting assembly consists of a take-up reel and a take-up reel stopper. The take-up reel stopper is symmetrically arranged on both sides of the take-up reel, and the take-up reel and the take-up reel stopper are fixed together by riveting.

[0010] Furthermore, the mainspring assembly consists of a mainspring spool, a mainspring shell, mainspring leaves, a mainspring shell cover plate, and an external retaining circlip. The mainspring leaves and the mainspring shell cover plates on both sides are placed inside the mainspring shell. The mainspring spool passes through the mainspring leaves and the mainspring shell cover plates on both sides and is fixedly connected to the inner ring of the mainspring leaves. The outer ring of the mainspring leaves is fixedly connected to the mainspring shell, and the end of the mainspring spool is fixed with an external retaining circlip.

[0011] Furthermore, the ratchet assembly consists of a ratchet cover plate, a ratchet plate, a ratchet housing, a ratchet lock, and a torsion spring. The ratchet plate, ratchet lock, and torsion spring are installed inside the ratchet housing and ratchet cover plate. The ratchet plate is mounted on the mainspring shaft. A ratchet lock is located below the ratchet plate. The lower end of the ratchet lock is connected to the ratchet housing by a bolt and can swing around the bolt. A torsion spring is installed on the ratchet lock, and a switch assembly is located in the middle of the ratchet lock.

[0012] Furthermore, the switch assembly consists of a cam and a switch lever. The cam is installed in the middle of the ratchet lock and connected to the switch lever. When the switch lever rotates, it drives the cam to rotate, and the cam contacts the ratchet lock, changing the motion state of the ratchet plate.

[0013] The steps for using a multi-functional bolt tightener are as follows:

[0014] S1, Multi-functional fastener fixing: Fix one end of the fixing seat or strapping to the tie-down seat or the cargo;

[0015] S2, Cable tie extended: Switch the switch assembly to the extended position. At this time, cable tie 2 is pulled out and cannot be retracted;

[0016] S3, Cable tie securing: Secure the other end of the cable tie to the cargo or another mooring seat.

[0017] S4, Multi-functional fastener tensioning: Switch the switch assembly to the retracted position. At this time, the strapping can only be retracted and cannot be extended. Tension the multi-functional fastener by turning the rocker handle to securely fasten the goods.

[0018] S5, Multi-functional fastener locking: When the switch assembly is switched to the locking position, the multi-functional fastener can neither extend nor retract and is in a locked state, and the goods are securely restrained.

[0019] S6, Multi-functional cable tie unlock: Switch the switch to the unlock position. At this time, the cable tie is in a free state, which can be extended and retracted. Loosen the cable tie from the goods, and the cable tie will automatically retract.

[0020] Compared with the prior art, the present invention has the following advantages:

[0021] (1) Through reasonable design, the present invention realizes that when the fastener is in the free position, the binding strap can be automatically retracted, which greatly improves the retraction efficiency of the fastener.

[0022] (2) By rationally arranging the various mechanisms and nesting them together, the present invention greatly reduces the space occupied by the bolting device while achieving multifunctional integration.

[0023] (3) By setting a retraction position and a crank handle, the fastener can be tightened more easily, making the goods more securely bound.

[0024] (4) By setting an extension position, the present invention can avoid holding the hand when moving the bolt in the early stage of fixing the goods, making it easier to move the bolt in the early stage of fixing the goods.

[0025] (5) The replaceable binding straps and fork-type rotating hooks in this invention can be adapted to the weight of the goods being secured, ensuring the portability of the securing device. Attached Figure Description
