Description

Technical Field

[0001] The utility model relates to the technical field of rotary connectors, in particular to a multifunctional universal rotary connector. Background Art

[0002] Connectors are parts widely used in different fields and industries. They are mainly used to connect different parts to achieve the functions of fixing, supporting and transmitting force. There are many types of connectors, among which the more common ones are rotating connectors, which are parts that can achieve connection in different directions and angles.

[0003] A rotary connector usually consists of a clamp, a rotatable rotating ball and a connector. Common clamps on the market are usually straight and flat with uniform thickness or thick in the middle and thin at both ends. Since the working principle of this clamp is to tighten the rotating ball by twisting the middle knob screw to bring the two clamps closer together, the final force-bearing position of the clamp is the two ends of the clamp. Therefore, if the clamp structure is straight and flat with uniform thickness or thick in the middle and thin at both ends, which is common on the market, when the clamping force is slightly large or the use time is slightly long, the two ends of the clamp will expand and deform outward, resulting in a situation where the lock cannot be tightened, resulting in the rotary connector not being firm enough and ultimately affecting the functionality and service life of the product, unless some very special and expensive materials are used to solve this problem, but the cost is extremely high, or the production process is more complicated and not broad-spectrum. Therefore, a multifunctional universal rotary connector is proposed to address the above problems. Utility Model Content

[0004] The utility model aims to provide a multifunctional universal rotating connector to solve the problem that the clamp is easy to expand and deform, cannot lock the rotating ball, and has insufficient firmness.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A multifunctional universal rotating connector comprises a connector body for rotation, wherein the connector body comprises a clamp, a rotating ball, a connecting head and a fixing bolt, the clamp being arched outwardly left and right and inwardly front and back and having a first groove which is an arc-shaped depression which does not fully wrap the sphere, a rotatable rotating ball is tightly fitted in the first groove formed by the clamp, one end of the rotating ball is fixedly connected to a connecting head which is cylindrical, a hole is formed in the middle of the clamp, a fixing bolt is provided in the middle of the clamp, the fixing bolt comprises a bolt rod and a rotating cover, a bolt rod is provided on one side of the clamp, and one end of the bolt rod is threadedly connected to the rotating cover.

[0007] Preferably, the clamps are arranged in groups of two on the outside of the rotating ball, and a plurality of second grooves arranged in an arch shape are provided on the inner side of the clamps.

[0008] Preferably, one end of the bolt rod is protruding in a hexagonal shape, and the bolt rod passes through a hole opened in the middle of the clamp.

[0009] Preferably, the clamp is thick at both ends and thin in the middle, and the edge of the rotating cover is arc-shaped.

[0010] Preferably, the clamp is arranged in an outwardly arched shape left to right and inwardly arched shape front to back, and the first groove formed in the clamp is arranged in an arc-shaped depression that does not fully wrap around the sphere.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model provides a connecting member main body, a clamp, a rotating ball, a connecting head and a first groove, which are arched outwards left and right and arched inwards front and back. The first groove, which is an arc-shaped depression that does not fully wrap the sphere, is provided in the clamp, so that when the two clamps clamp the rotating ball, there is not only a clamping force but also a pushing force toward both ends, so that the clamp and the rotating ball are better fitted and locked, and the locking force during locking is increased, so that the locking effect is better. The first groove, which is an arc-shaped depression that does not fully wrap the sphere, increases the inclination and rotation angle of the rotating ball. The second groove, which is arched and provided on the inner side of the clamp, reduces the material consumption without affecting the overall strength of the clamp. The fixing bolt, bolt rod, limiter, rotating cover and hole are provided, and the bolt rod passes through the holes provided by the two clamps. By rotating the rotating cover, the arched clamp is fitted with the rotating ball to generate a certain clamping force and a pushing force toward both ends, thereby increasing the overall firmness of the connecting member main body.

[0020] A multifunctional universal rotating connector comprises a connector body 1 for rotation, the connector body 1 comprises a clamp 11, a rotating ball 12, a connector head 13 and a fixing bolt 14, the clamp 11 is provided with a first groove 2, a rotatable rotating ball 12 is tightly fitted in the first groove 2 provided by the clamp 11, one end of the rotating ball 12 is fixedly connected to a connector head 13 arranged in a cylindrical shape, a hole 4 is provided in the middle position of the clamp 11, a fixing bolt 14 is provided in the middle position of the clamp 11, the fixing bolt 14 comprises a bolt rod 141 and a rotating cover 142, a bolt rod 141 is provided on one side of the clamp 11, and one end of the bolt rod 141 is threadedly connected to the rotating cover 142.

[0021] Two clamps 11 are arranged in a group on the outside of the rotating ball 12, and a plurality of second grooves 3 in an arched shape are provided on the inner side of the clamps 11 to effectively clamp the rotating ball 12. At the same time, the second grooves 3 provided reduce the material consumption without affecting the strength of the clamps 11; one end of the bolt rod 141 is hexagonally protruding, and the bolt rod 141 passes through the hole 4 provided in the middle of the clamp 11, which is convenient for the installation of the bolt rod 141; the clamps 11 are thick at both ends and thin in the middle, and the edge of the rotating cover 142 is arc-shaped, which is convenient for opening the two ends of the clamps 11 and rotating the rotating cover 142; the clamps 11 are arched outwards left and right and inwards front and back, and the first groove 2 provided on the clamps 11 is an arc-shaped depression that does not fully wrap the sphere, so that the clamps 11 produce a certain clamping force and a pushing force toward both ends when they fit with the rotating ball 12.

[0022] Working process: When the multifunctional universal rotating connector is in use, first place the connector body 1 in a suitable position, and rotate the rotating cover 142, which is on the outside of one end of the bolt rod 141, and moves toward the clamp 11 while rotating, so that the first groove 2 opened in the clamp 11 fits tightly with the rotating ball 12. When the first groove 2, which is an arc-shaped depression that does not fully wrap the sphere, clamps the rotating ball 12, a part of the rotating ball 12 will extend beyond the edge of the clamp 11. While locking the rotating ball 12, the clamp 11, which is arched outwards left and right and arched inwards front and back, is locked in the rotating cover. Under the action of 142 and the bolt rod 141, a thrust is generated in the direction of the rotating ball 12, thereby increasing the firmness of the connector body 1. When connected with other parts, the connecting head 13 is inserted into a suitable position of the part, and the rotating ball 12 rotates in the first groove 2 opened in the clamp 11, driving the connecting head 13 to rotate in the same direction, so that the part is in a rotatable state. By setting the clamp 11 with a left-right outward arch and a front-back inward arch on the connector body 1 and the fixing bolt 14 for locking the rotating ball 12, the firmness of the connector body 1 is increased while locking the rotating ball 12.
