Abstract
Description
Technical Field
[0001] The present invention particularly relates to an open hook type connection device for connecting an object to a linear object. Background Art
[0002] In daily life and industrial applications, it is often necessary to temporarily connect various objects (such as keys, accessories, tools, ID cards, etc.) to linear objects (such as thin rods, rings, slings, key rings, etc.). Currently common connection devices include small key rings, open rings, buckles, lobster buckles, mountaineering buckles, and red gall buckles, but they all have significant defects in certain aspects. To put an object into a small key ring or take it out of it, you need to use your fingernails to pry open the spring wire and rotate it a full circle, which is cumbersome. The open ring connection is easy to loosen. The lobster buckle and mountaineering buckle have complex structures, the parts are easily damaged, and hidden damage is difficult to detect. The buckle requires the plug and socket to match and the connection is not firm. The red gall buckle is asymmetrically stressed and has strict requirements on material strength. Therefore, the existing technology cannot take into account the simplicity of structure, connection reliability and convenience of operation. Summary of the invention
[0003] In order to solve the above problems, the present invention provides an open hook type connection device which has a simple structure, a firm connection and is easy to use.
[0004] The open hook-type connection device that can achieve the above effect includes a pair of hook bodies that are flipped over each other, and the bottoms of the two hook bodies form an integral structure through an elastic link. In a natural state, the ends of the hook bodies fit the hook body of the opposite hook body. The entrance and exit of the hook body are blocked by the hook handle of the opposite hook body, and the open hook-type connection device is in a closed state. The tops of the hook bodies are tilted outward or staggered to form an introduction port. When an external force is applied, the two hook bodies separate to form a channel for linear objects to pass through.
[0005] The open hook type connection device provided by the present invention has the following beneficial effects compared with other existing technologies.
[0006] 1. Simple structure: It can be made by bending only a section of elastic wire.
[0007] 2. Sturdy and durable: Its structure is balanced in force and the connection is reliable.
[0008] 3. Easy to use: It can be easily inserted into and removed from linear objects. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The present invention will be described in detail below with reference to the accompanying drawings and two most preferred embodiments: Figures 1-3 As shown, an embodiment of the open hook-type connection device provided by the present invention includes a pear-shaped ring processed from an elastic wire, with a pair of mutually reversed hook bodies 1 formed at both ends, the bottoms of the two hook bodies are connected by an elastic connection part 2, and the tops 3 of the hook bodies are separated from each other to form an inlet 4.
[0015] As Figure 1 shown, in the natural state of this embodiment, the two hook bodies 1 lean against each other, the end 5 of the hook body fits with the hook handle 1 of the opposite hook body, and the inlet and outlet of the hook body are blocked by the hook handle of the opposite hook body, realizing locking.
[0016] As Figure 2 shown, assuming that the position of the bottom 2 is limited in this embodiment, when an external force is applied along the position and direction from the hollow arrow to the solid arrow, the linking device undergoes elastic deformation, resulting in the separation of the end 5 of the hook body from the hook handle 1 of the opposite hook body, forming a channel 6.
[0017] Figure 3 As shown, this is a specific application scenario of this embodiment. When the user needs to put the open hook-type connection device 10 onto a linear connection object such as a key ring 11, the user inserts the open hook-type connection device 10 into the key ring 11 through the top inlet 4, and the channel 6 is opened under the pushing action of the key ring 11. The key ring 11 continues to be inserted until it passes through the end 5 of the hook body, and then the end 5 resets under the elastic action, and the channel 6 closes, completing the putting-on.
[0018] When the user needs to remove the open hook - type connecting device 10 from a linear connecting object such as a key ring 11, the user pinches the bottom of the connecting device 10, moves the end of the hook body 5 inside the key ring, and twists the open hook - type connecting device in the direction shown by the hollow arrow. Under the action of torsion, the end of the hook body 5 separates from the hook body of the opposite hook body blocked by the key ring 11, so that the channel 6 is opened. After the open hook - type connecting device 10 is pulled out from the key ring 11 along the channel 6, the end 5 returns to its original position under the action of elasticity, and the channel 6 is closed.
[0019] Figure 4 , Figure 5 The figure shows another embodiment of the open hook - type connecting device provided by the present invention. A pair of elastic hook bodies 21 extend from the top of the fitting 20. There is an insertion groove 22 between the tops of the two hook bodies. Without external force, the two hook bodies 21 fit together.
[0020] When the user needs to put the fitting onto a linear connecting object such as a sling or a ring, the user inserts the sling or the ring into the insertion groove until the sling or the ring passes through the end of the hook body 23, that is, the end returns to its original position by elasticity, and the fitting - on is completed.
[0021] When the user needs to remove the fitting from the sling or the ring, the user passes the sling or the ring around the end of the hook body 23. The hook bodies separate from each other under the extrusion of the sling or the ring to form a channel. After the sling or the ring is pulled out from the fitting along the channel, the elastic hook bodies reset and fit together again.
[0022] The embodiments of the present invention are only for illustration and do not limit its patent scope. Any changes, modifications, additions or substitutions made within the substantial scope of the invention, as well as equivalent implementations or changes without departing from the spirit of the invention, are equally included in the scope of patent protection.
