Description

Technical Field

[0001] The utility model belongs to the technical field of joints and relates to a quick self-locking joint for connecting a pole and a net bag in the fields of fishing, fruit picking, catching, river cleaning, etc. Background Art

[0002] In modern fisheries, agriculture and environmental protection work, we often see various connectors being widely used in fishing, fruit picking, fishing, river cleaning and other fields. These connectors are often designed to easily insert one end of the pole into the middle connector, and the other end can be flexibly connected to tools such as net bags and fruit picking baskets. However, some existing connection methods have some problems that cannot be ignored, which require us to explore in depth and seek better solutions.

[0003] First, in the existing technology, there are two common connection methods: one is to connect one end of the rod to the joint by gluing; the other is to open a through hole on the joint body, insert one end of the rod into the middle joint, and then use a rivet to pass through the through hole to anchor one end of the rod to the joint. However, both methods have some obvious shortcomings.

[0004] Although the gluing method is simple to operate, there is a risk that the rod will fall off during use. The strength of the gluing is affected by many factors, such as temperature, humidity, and frequency of use. Once these factors change, the rod may fall off the joint, affecting work efficiency and safety. In addition, the gluing method requires additional glue and other materials, which increases costs and is not environmentally friendly.

[0005] For the rivet method, although the connection is more secure, the friction and wear between one end of the rod and the joint may cause looseness and shaking during long-term use. This shaking will not only affect the use effect, but may also damage the rod and joint, increasing the frequency of repair and replacement. In addition, the installation of rivets also requires certain skills and experience. Improper operation may lead to loose installation or damage to the rod and joint.

[0006] Therefore, in order to solve the above problems, it is necessary to develop a new joint that can be quickly installed and that connects the pole and the joint firmly. Utility Model Content

[0007] In view of this, the purpose of the utility model is to overcome the deficiencies of the existing related technologies and provide a quick self-locking connector which should have a simple and quick installation process, a firm and reliable connection, and can withstand long-term friction and wear without being easily loosened or damaged.

[0008] In order to achieve the above-mentioned object, the utility model provides a quick self-locking joint, which comprises a joint body, an extruded fastener and a kit; wherein one end of the joint body is open, and the joint body has a hollow cavity extending inward from the opening, and the other end of the joint body is provided with a first internal thread; the first internal thread extends inward from the end surface of the other end of the joint body;

[0009] It also includes an extrusion structure and a push structure;

[0010] The extrusion structure is as follows: the extrusion fastener is annular; a fracture is provided on the annular extrusion fastener, and a gap is provided between the fractures; the outer periphery of the extrusion fastener has a first annular inclined surface; the hollow cavity of the joint body is provided with a second inclined surface adapted to the first inclined surface;

[0011] The pushing structure is capable of moving the joint body and the sleeve toward each other in the axial direction;

[0012] The extrusion fastener is disposed in the hollow cavity of the joint body;

[0013] When the joint body and the sleeve move toward each other in the axial direction, the sleeve can press against one end surface of the extrusion fastener to push the extrusion fastener to move, and the first inclined surface on the extrusion fastener and the second inclined surface on the hollow cavity in the joint body form an extrusion, so that the extrusion fastener contracts in the radial direction, so that the extrusion fastener is locked and fixed on the rod, thereby realizing a quick fixed connection between the rod and the self-locking joint.

[0014] Furthermore, the pushing structure is as follows: an external thread is provided on the sleeve, and a second internal thread is provided at the opening of the joint body; the joint body and the sleeve are moved toward each other in the axial direction by the external thread and the second internal thread.

[0015] Furthermore, after the extrusion fastener shrinks in the radial direction, the diameter of the inner ring of the extrusion fastener is smaller than the diameter of the inner ring of the sleeve.

[0016] Furthermore, the second inclined surface is in an outwardly expanding annular shape.

[0017] Furthermore, one end of the second annular inclined surface is directly the same as the diameter of the hollow cavity, and the diameter of the annular inclined surface gradually increases from one end to the other end.

[0018] Furthermore, the width of the extruded fastener is about 6 mm.

[0019] Furthermore, the outer circumference of the kit is provided with flat areas on opposite sides for easy handholding.

[0020] Furthermore, the outer periphery of the joint body is provided with anti-slip grooves.

[0021] Furthermore, the distance between the opening surface at one end of the joint body and the first internal thread is about 3 mm.

[0022] When the connector body and the sleeve move toward each other in the axial direction, the sleeve can press against one end face of the extrusion fastener to push the extrusion fastener to move, and the first inclined surface on the extrusion fastener and the second inclined surface on the hollow cavity in the connector body form an extrusion, so that the extrusion fastener contracts in the radial direction, thereby locking and fixing the extrusion fastener on the rod, and realizing a quick fixed connection between the rod and the self-locking connector. It has at least the following beneficial effects:

[0023] 1. The quick self-locking joint provided by the utility model cleverly utilizes the principle of the inclined plane, and realizes the contraction and fixation of the extruded fastener through simple movement and extrusion. This not only makes the installation process simple and quick, avoiding cumbersome additional procedures such as using glue, punching, anchoring nails, etc., but also the connection is firm and reliable, and is not easily disturbed by external factors such as temperature and humidity.

[0024] 2. In addition, since the extruded fastener shrinks in the radial direction, the contact area between it and the rod increases, the friction is enhanced, and it can withstand long-term friction and wear. This design greatly extends the service life of the self-locking joint and is not prone to loosening or damage.

[0025] 3. In practical applications, this quick self-locking connector can be widely used in various occasions that require quick and firm connection, such as scoop nets, fishing rods, photographic equipment, outdoor equipment, etc. Its simple installation, reliable connection and long service life make it a very practical fastener solution.

[0026] 4.
