Description

Corner joints for building rods

The invention relates to a rod joint, in particular to a rod corner joint for construction which has both easy assembly and universal adjustment of the angle.

Press, a conventional rod steering joint structure, such as the "Adjustable Angle Joint for Metal Pipes (Additional One)" approved by the Bureau on March 21, 1991 with the Announcement Certificate No. 481190, which has two options The first and second mating parts are combined with each other, and these mating parts are respectively provided with extension sleeves as joints; at one end of the extension sleeve of the first mating part, two separate sphere constituent pieces are provided to form a middle Clamping mouth; the second mating part and the middle clamping mouth are provided with a spherical middle component for assembly in the middle clamping mouth, and one of the first mating parts can be locked into the second mating part with a bolt from the outside of one of the components of the first mating part The central screw hole of the middle partition; the opposite part of one of the constituent pieces of the first mating member locked by the above bolts, and the junction of the middle partition of the second mating member and its inner periphery can be selected to be joined with more directional joints, However, it is not difficult to find out that there are some shortcomings in the above-mentioned conventional structure. The main reasons are as follows: the connection of the first and second mating parts still needs to be locked and fixed by bolts, and the cost of parts is high. There are many components and time-consuming assembly, and the bolts exposed on the surface of the sphere have disadvantages such as unsightly and easy to rust. Moreover, the first and second mating parts can only form a sheet along the sphere and the sphere. Tool The component is rotated in a plane shape, and its adjustable angle is limited, which is not suitable for adjusting the height difference of different heights.

In view of this, the inventor of the present invention has been engaged in the manufacturing, development and design of related products for many years. Aiming at the above-mentioned goals, after detailed design and careful evaluation, he finally obtained a practical invention.

The technical problem to be solved by the present invention is to provide a corner joint of a rod for construction in view of the above-mentioned shortcomings existing in the prior art.

Both semi-circular joints are formed with a semi-spherical surface, and the other surface of the semi-circular spherical surface is provided with a joint plane, and the center of the joint plane is provided with a shaft groove. A shaft is penetrated through the shaft groove, and the semicircular joint is integrally extended with a joint seat at the periphery, and the joint seat is protrudingly provided with a connecting rod facing the opposite direction of the semicircular joint, and one end of the two connecting sleeves is retracted to form an accommodation And a through hole is opened in the center of the accommodating chamber, and the two connecting sleeves are sleeved on the joint seat by the accommodating chamber, and the connecting rod is allowed to pass through the through hole to form a limit, and the connecting sleeve is in the A blocking arc is formed on the periphery of the opening of the accommodating chamber, and the blocking arc is ring-shaped against the semi-spherical surface.

A head is formed at the end of the connecting rod, and a C-shaped buckle is sleeved on the head, and the C-shaped buckle abuts against the periphery of the through hole of the connecting sleeve, so that the semicircular joint is rotatably confined to the connecting sleeve .

Wherein the connecting sleeve is provided with at least one lock hole, and the lock hole is locked A screw is provided, and a rod inserted in the connecting sleeve is fixed by the screw.

The semicircular joint, the shaft and the connecting sleeve are all made of plastic materials.

Wherein the connecting sleeve is penetrated with a rod, and the rod is fixed with a cover at one end that penetrates the connecting sleeve, and the cover is opened with a perforation, and there is a gap between the cover and the rod that communicates with the perforation An inner groove, a head is formed at the end of the connecting rod, the head passes through the perforation, and the head is confined in the inner groove, so that the semicircular joint is rotatably confined to the connecting sleeve, and The connecting sleeve and the rod are connected in a lock-free manner.

Wherein the joint seat forms an abutting surface toward the semicircular joint, and a damping element is arranged on the abutting surface, and the damping element contacts the abutting surface, the inner wall surface of the accommodating chamber and the semi-spherical surface at the same time, thereby providing proper rotation resistance.

The first main purpose of the present invention is that the shaft is inserted through the shaft grooves of the two semicircular joints, and the accommodating chamber is sleeved with the joint seat, and the blocking arc is used to abut against the semicircular spherical surface, thereby In the case that the connecting sleeve cannot be separated from the semicircular joint, the two semicircular joints can be connected by avoiding locking, so as to have the effect of easy assembly and lower production cost.

The second main purpose of the present invention is that the two semicircular joints can form a plane-like relative rotation with the shaft as the axis, and the connecting sleeve and the semicircular joint can be opposed to each other with the accommodation chamber and the joint seat. Rotation means to rotate along the direction of the connecting rod, and also through the direction of the shaft and the direction of the connecting rod. When rotating, the two rods can swing in any direction to adjust the position, which can be applied to the different corner angles and height differences of the handrail or railing of the stairs, so as to effectively improve its practicability.

Other purposes, advantages and novel features of this creation will be more apparent from the following detailed description and related drawings.
