Description

Connecting device

The invention relates to a connection device for connecting workpieces.

With the rapid development of technology, more and more electronic devices have entered people's lives, such as televisions, projectors, cameras, monitors, etc., and various components inside the electronic device need to be connected and assembled. .

At the same time, the application of electronic devices is becoming more and more widespread. For example, projectors currently have four projection modes: front projection, rear projection, ceiling projection, and ceiling rear projection depending on the actual use environment. Ceiling projectors and ceiling-mounted projectors need to have a connection device to connect the projector to the boom to achieve the projector's ceiling projection and ceiling rear projection. For example, in public places, the television set is usually hung in a high place for the convenience of the viewer. The connection of the TV set to a high position is also required. In addition, electronic devices such as cameras and monitors may be suspended at high altitudes for their special applications. In this case, connection devices are also required.

The connecting device is generally formed by heating the nut in an induction heating mode after the plastic casing of the electronic device is molded, and pressing the heated nut into the corresponding mounting hole of the plastic casing.

However, the nut squeezes the plastic around the mounting hole during the pressing process, and the extruded plastic scrap is easily accumulated directly under the nut, and the plastic scrap accumulated under the pressure is moved under the pressure to the threaded through hole of the nut, thereby The threaded through hole is blocked, resulting in insufficient connection depth of the connecting device.

In view of the above, it is necessary to provide a connecting device that prevents the threaded through hole from being blocked to ensure the connection depth.

A connecting device includes a nut having a threaded through hole, a stop portion and a bearing portion. The stop portion includes a body portion and at least two protrusions extending perpendicularly to both ends of the body portion. The body portion is provided with a first through hole corresponding to the threaded through hole, and each of the protruding portions is provided with a second through hole. The carrying portion includes a substrate and a limiting portion extending perpendicular to the substrate and having a shape corresponding to the shape of the nut. The outer sidewall of the limiting portion has at least two clamping members that cooperate with the second through hole. The limiting portion and the substrate form a receiving space to receive the nut. The body portion is located at the top of the limiting portion away from the substrate and aligns the first through hole with the threaded through hole. The clamping member passes through the second through hole to clamp the stopper and define the nut in the receiving space.

Compared with the prior art, the connecting device receives the nut by the receiving space formed by the limiting portion and the substrate, and engages with the clamping member by the stopping portion to clamp the nut into the receiving space, thereby avoiding the nut. The threaded through holes are blocked to ensure the connection depth of the connecting device.

The invention will be further described in detail below with reference to the accompanying drawings.
