Examples

Please refer to fig. 1-6. The present embodiment provides a ceiling mount 10 for suspended mounting of an apparatus 11 such as a projector, which includes a pipe 12 and a rod 13 that are fitted by insertion, a pre-locking mechanism 14 for pre-locking the pipe 12 and the rod 13, and a locking mechanism 15 for locking the pipe 12 and the rod 13. The pre-locking mechanism 14 comprises an elastic piece 16 and a limit pin 17; the pipe fitting 12 is provided with a through hole 18 penetrating through the side wall of the pipe fitting, and the limiting pin 17 is movably matched in the through hole 18 and can extend into the inner wall of the pipe fitting 12 or withdraw from the inner wall of the pipe fitting 12; the elastic part 16 is elastically supported between the pipe 12 and the limit pin 17 and is used for elastically pressing the limit pin 17 into a state of extending into the inner wall of the pipe 12; the front end of the outer circumference of the rod 13 is provided with a slope P1 and a radially recessed limiting groove C3 arranged behind the slope P1, so that during the insertion of the rod 13 into the tube 12, the limiting pin 17 is pushed back by the slope P1 and pressed into the limiting groove C3 by the elastic member 16 to limit the movement of the rod 13 relative to the tube 12.

The ceiling support 10 in the scheme has the pre-locking mechanism 14 and the locking mechanism 15, when the equipment 11 needs to be installed, the rod piece 13 can be connected with the equipment 11 to be hung and installed, then the rod piece 13 is inserted into the pipe fitting 12 until the limiting pin 17 of the pre-locking mechanism 14 is clamped into the limiting groove C3 of the rod piece 13, and pre-locking is achieved; due to the pre-locking of the limiting pin 17 and the limiting groove C3, an operator does not need to support the supporting device 11 any more, and at the moment, the locking mechanism 15 can be conveniently used for final locking action, so that the laborious and difficult operation of supporting the supporting device 11 and performing the locking action at the same time is avoided, and the operation safety is ensured.

Similarly, when the equipment 11 needs to be removed, the locking mechanism 15 is firstly released, and at the moment, the equipment 11 still continues to be hung on the pipe 12 due to the existence of the pre-locking mechanism 14 and cannot be disengaged; the spacing pin 17 is then withdrawn to unlock the pre-lock mechanism 14 and the device 11 can be removed.

Therefore, in the scheme, the pre-locking operation can be realized by moving along the axial direction all the time, and the operation is convenient; after this operation is completed, the device 11 is pre-locked, freeing both hands to perform subsequent locking actions that may be complex and laborious.

As shown in fig. 4 and 5, in the embodiment, the front pipe wall 19 of the pipe 12 is provided with a plurality of strip-shaped grooves C4 parallel to the axial direction thereof, and the plurality of strip-shaped grooves C4 divide the front pipe wall 19 of the pipe 12 into a plurality of pipe segments 20; the locking mechanism 15 includes a hoop 21 that can be tightly held around the outer circumference of the front pipe wall 19 of the pipe 12, and a locking wrench 22 that is connected to the hoop 21 and can be pulled to radially hold or release the hoop 21. In the illustrated embodiment, the four strip-shaped grooves C4 are uniformly distributed along the circumferential direction to divide the front-end tube wall 19 of the tube 12 into four tube sheets 20. The locking operation can be conveniently achieved by cutting the front end wall 19 of the tube 12 and tightening or loosening the practical and releasable anchor ear 21. The tightness of the hoop 21 in this embodiment can be achieved by using the prior art, such as cam locking by providing a cam surface on the locking wrench 22, which is not described herein. Optionally, the outer circumference of the front pipe wall 19 of the pipe 12 is provided with a concave annular groove C1, and the hoop 21 is fitted in the annular groove C1. The foremost end of the outer peripheral surface of the pipe member 12 has a convex collar 23 to restrict the hoop 21 from coming out of the annular groove C1 in the radial direction. With this arrangement, the front end wall 19 of the pipe member 12 is made thinner by the annular groove C1, so that it is easy to expand or hold the rod member 13 in the radial direction. Referring mainly to fig. 4 and 5, in the present embodiment, the outer periphery of the pipe member 12 is provided with a circumferential wall 24 opening toward the front end thereof, and the circumferential wall 24 and the outer periphery of the pipe member 12 define a circumferential groove C2 facing the front end; the forward end of the tube member 12 extends into the annular groove C2 and is confined to the inside of the peripheral wall 24. This arrangement can limit the range of movement of the forward end of segment 20 to the outside.

Referring to fig. 4 and 5 again, in the present solution, the inclined plane P1 is a conical ring surface, and the limiting groove C3 is an inward concave annular groove. This arrangement allows the position-limiting pin 17 to be guided by the inclined surface P1 into the position-limiting groove C3 for position-limiting when the rod members 13 are fitted to each other at arbitrary circumferential relative positions.

In order to facilitate the arrangement of the pre-tightening mechanism, the periphery of the pipe 12 in the scheme is provided with a ring bulge 25 with the wall thickness expanding outwards along the radial direction, and the through hole 18 is arranged on the ring bulge 25. The through hole 18 is a stepped hole with a small inner part and a large outer part; the limit pin 17 comprises a limit part 26 at the front end thereof, a limit ring part 27 with the diameter larger than that of the limit part 26 and a head part 28 at the rear end thereof; the elastic element 16 is a compression spring, which is sleeved on the periphery of the limit pin 17, and one end of the elastic element abuts against the limit ring part 27, and the other end of the elastic element abuts against the limit ring part 27 forward, so as to elastically press the limit part 26 into the limit groove C3. The head portion 28 extends beyond the through hole 18 to facilitate the gripping operation.

With reference to fig. 4, 5 and 6, the ceiling bracket 10 in the present embodiment further includes a mounting block 29 for fixing the device 11, and a connecting plate 30 is vertically disposed on a rear surface of the mounting block 29; the rear end of the rod 13 is provided with two spaced lugs 31, and the connecting plate 30 is sandwiched between the two lugs 31 and connected to the two lugs 31.

In this way, the attitude of the device 11 can be conveniently adjusted by adjusting the angle of the connecting plate 30 relative to the ear plate 31.

Referring to fig. 1 again, the upper portion of the pipe 12 of the ceiling bracket 10 in the present embodiment may be connected with a connection pad 35 for connecting with a ceiling surface, and then the connection pad 35 is configured to be connected with an embedded part 34 embedded in the ceiling, so as to realize suspension installation.

Referring to fig. 7, the ceiling bracket 10 of the present embodiment is further provided with a power supply bracket 36 for mounting a power supply 39, the power supply bracket 36 includes a frame 37 for fixing the power supply 39, and two pipe clamps 38 are connected to the frame 37 and connected to the outer periphery of the pipe 12 through the pipe clamps 38. A power supply 39 is connected to the device 11 via a cable for supplying power to the device 11.
