Problems solved by technology

However, after careful analysis, there is also a fly in the ointment. The adjusting bolt assembly of the above-mentioned connecting piece is located under the connecting nut, and the space for the manipulator or hand tool to enter is small, and it is inconvenient to rotate, and the connecting nut needs to be fixed at the same time when rotating the adjusting bolt. Otherwise, Slippage will occur and work efficiency will be affected

Embodiment 1

[0027] Such as figure 1 and figure 2 As shown, an automatic adjustable connecting piece with upper screw and lower lock includes an upper connecting rod 1 and a lower connecting rod 2. The ends of the upper connecting rod 1 and the lower connecting rod 2 have an upper connecting cavity 3 and a lower connecting rod respectively. Cavity 4, preferably, the outer wall of upper connecting cavity 3 and lower connecting cavity 4 is inflated, which is convenient for making and connecting, and there are internal threads in upper connecting cavity 3 and lower connecting cavity 4, and the internal screw of described upper connecting rod 1 Connected with a plug-in rod 5, the lower connecting rod 2 is internally screwed with a clamping mechanism 7, the outer wall of the plug-in rod 5 has a ring gear 6 integrally formed with the plug-in rod 5, when the plug-in rod 5 is inserted into the card When in the connecting mechanism 7, rotating the ring gear 6 can adjust the position of the end of...

Embodiment 2

[0036] The structure and working principle of this embodiment are basically the same as that of Embodiment 1, the difference is that, as image 3 and Figure 4 As shown, the end of the insertion rod 5 has a step-shaped clamping platform 9, and the clamping mechanism 7 includes a spring assembly 14 screwed to the lower connection chamber 4. When the insertion rod 5 is inserted into the spring assembly 14 At this time, rotating the ring gear 6 can make the card table 9 close to the spring assembly 14 and make the card table 9 and the end of the spring assembly 14 form a snap fit. Since the structure of the shrapnel assembly 14 is relatively simple, it is easy to assemble and use.

[0037] combine Figure 6 As shown, the shrapnel assembly 14 includes a shrapnel threaded portion 15 that is threadedly engaged with the lower connection chamber 4 , and the end of the shrapnel threaded portion 15 is provided with a number of springs evenly distributed along the axial direction of th...

Abstract

The invention belongs to the technical field of buildings and relates to an automatic adjustable connecting piece capable of achieving upper screwing and lower locking. The automatic adjustable connecting piece capable of achieving upper screwing and lower locking comprises an upper connecting bar and a lower connecting bar. An upper connecting cavity is formed in the end of the upper connecting bar, and a lower connecting cavity is formed in the end of the lower connecting bar. Internal threads are arranged in the upper connecting cavity and the lower connecting cavity. An insertion bar is connected into the upper connecting bar in a threaded mode. A clamping mechanism is connected into the lower connecting bar in a threaded mode. A gear ring is arranged on the outer wall of the insertion bar, and the gear ring and the insertion bar are integrally formed. When the insertion bar is inserted into the clamping mechanism, the position of the end of the insertion bar in the clamping mechanism can be adjusted by rotating the gear ring, so that the insertion bar and the clamping mechanism are matched in a clamped mode. By the adoption of the automatic adjustable connecting piece capable of achieving upper screwing and lower locking, mechanical operation for connection is facilitated; and in addition, the connecting distance can be adjusted, both an anti-pulling effect and an anti-pressing effect can be achieved, and connection is firm and reliable.

Description

technical field [0001] The invention belongs to the technical field of construction, and relates to an automatic adjustable connecting piece for screwing up and locking down, which is suitable for quick connection between objects. Background technique [0002] Connectors are usually used for the connection between two objects, especially in recent years, because of their convenience and speed, they have been developed rapidly. However, the existing connectors have certain limitations because the distance between them cannot be adjusted. For this reason, the applicant has previously applied for an adjustable distance connector [Application No.: 201410042392.8], which includes two connectors, one of which is provided with a plug connector, and the other connector is provided with a An adjusting bolt assembly capable of adjusting the length, the plug joint can be inserted into the adjusting bolt assembly, when the adjusting bolt assembly adjusts the length, the plug joint can s...
