Abstract

The utility model relates to a lock connecting device of two rods. The rod head end of one rod is a pipe-shaped joint (2), the utility model is provided with a lining core (3), and the lining core (3) is fixed in the joint (2) in a detachable mode. The utility model is provided with a lock cap (1), the top of the lock cap (1) is provided with a circular hole, and the lock cap is fixed outside the joint (2) in a detachable mode. The threaded parts which has inner support force of pipes of two thin walls which are fixedly connected have the advantages of uniform dispersion of stress, no deformation, no break and high durability.

Description

Two rod member lock connectors

The utility model relates to two rod member lock connectors, is meant the two rod member lock connectors that are used for the book tube wall especially.

At present, during two rod members of light wall pipe wall are connected and fixed, the straight plug-in type of the employing that has, it is that pipe cooperates with the diameter of outer tube and the frictional force that produces fixes in relying on, this be connected and fixed service time long after, because of repetitious friction cause in pipe change slightly with the diameter of outer tube, thisly fixingly will occur that pipe is easy to skid off in loosening the making.And another kind is to adopt nut and two pipes are fixedly connected, and after two pipes of book tube wall had been processed screw thread, the tube wall transverse gage became book, under stress, has helical thread portion yielding or fracture because of no support force in managing.

The purpose of this utility model provides a kind of two rod member lock connectors, and it can make the helical thread portion of the interior support force of Guan Zaiyou of two fixedly connected book walls, and stress evenly disperses, and can not be out of shape, and can not fracture, and is durable in use.

Technical solution of the present utility model is, is tube-shaped joint at the rod head end of a bar, and a lining core is arranged, and core is dismountable is fixed in the joint for lining, and a lock nut is arranged, and there is a circular hole on the top of lock nut, and lock nut is demountable to be fixed in outside the joint.

The slotted eye of the rarest two longitudinal openings of the above joint, slotted eye is divided into minimum two horizontal disjunct independent sectors with joint.

The outer wall of the utility model joint is the face of rising from adaptor tube oral area to joint tail end, and the face of this rising can be inclined-plane or the arc shaped surface that rises, and on the face of its rising screw thread is arranged.

Above the utility model lock nut is that one side is uncovered, and another side has the top, and the diameter that circular hole is gone up on its top is bigger than the pipe bar that need plug into, and the diameter of lock nut matches with joint, and the lock nut inwall has screw thread.

The lining seat of lining core of the present utility model has the embedding of stretching out that adapts with the joint slotted eye to decide the pin of usefulness, and lining core lining seat upper end is a bushing pipe that protrudes upward, and its lining pipe stretches in the pipe of desiring to plug into, and diameter matches with the pipe inner diameter of desiring to plug into.

The bar that above the utility model has a tube-shaped joint can be a bar independently, or is inserted in the stretchable bar in another bar.

The utility model has the advantages that the helical thread portion of support force in the Guan Zaiyou that can make two fixedly connected book walls, stress evenly disperses, and can not be out of shape, and can not fracture, and is durable in use.

Below in conjunction with accompanying drawing embodiment of the present utility model is described:

Shown in Fig. 1,2, the utility model is the tube-shaped joint 2 at the rod head end of a bar, joint 2 has the slotted eye of three longitudinal openings, slotted eye is divided into three horizontal disjunct independent sectors with joint 2, the outer wall of joint 2 is the arc shaped surface of rising from adaptor tube oral area to joint tail end, and screw thread is arranged on the arc shaped surface.A lining core 3 is arranged, and lining core 3 dismountable being fixed in the joint 2 have the top of a lock nut 1, lock nut 1 that a circular hole is arranged, lock nut 1 demountable being fixed in outside the joint 2.Lock nut 1 is that one side is uncovered, and another side has the top, and the diameter that circular hole is gone up on its top is bigger than the pipe bar that need plug into, and the diameter of lock nut matches with joint, and the lock nut inwall has screw thread.The lining seat of lining core 3 has three embeddings of stretching out that adapt with joint 2 slotted eyes to decide the pin of usefulness, and lining core 3 lining seat upper ends are a bushing pipe that protrudes upward, and its lining pipe stretches in the pipe of desiring to plug into, and diameter matches with the pipe inner diameter of desiring to plug into.

Shown in Fig. 3,4,5, the bar that has tube-shaped joint 2 of the present utility model can be the stretchable bar that is inserted in another bar.

The utility model is that three pin that will serve as a contrast core 3 are earlier inserted in the opening slotted eye of joint 2, thereafter plug is pressed onto the end, lock nut 1 is inserted on the joint 2 again, and the pipe bar of the usefulness of plugging into of the pipe bar desiring to plug into or apparatus is inserted in the circular hole on lock nut 1 top, be inserted between joint 2 and the lining core 3, tighten lock nut 1 thereafter.Because the outer surface of joint 2 is an arc shaped surface that rises, and three longitudinal opening slotted eyes are arranged, when therefore lock nut being tightened downwards, joint 2 is subjected to the pressure of lock nut and inwardly shrinks, and refutes the pipe bar that connects and is fixed thereby clamp to insert.Insert in addition and refute the uniform pressure that the pipe that connects is subjected to joint 2 outward, and in served as a contrast the support force of core 3, so can be fixedly connected reliably, again can the stress effect and cause the distortion of joint part and fracture, durable in use.

Fig. 6,7,8,9,10 is the fish jar apparatus assembly parts of application examples of the present utility model, all can be docked with on the bar of lock connector of the present utility model, both convenient the use, reduced by an apparatus again and joined the worried and waste of bar, reduce the merchandise cost and the packaging volume of combination apparatus, thereby helped promoting the use of of society.
