Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention and the accompanying drawings. It should be noted that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example one

Referring to fig. 1 to 3, an embodiment of the present invention provides a three-dimensional strip-shaped suspended ceiling, including a hoisting component 1, a main keel 2, a three-dimensional mounting component 3, a clamping component 4 and a strip-shaped ceiling 5; the main keel 2 is hung below the hoisting component 1; the three-dimensional mounting assembly 3 comprises a sliding member 6 and a rotating member 7, the sliding member 6 is connected with the main keel 2 in a sliding mode, a first locking device 8 is arranged on the top side of the sliding member 6, a connecting arm 9 is fixedly arranged on the sliding member 6, the rotating member 7 is connected with the connecting arm 9 in a rotating mode, and a second locking device 10 is arranged between the rotating member 7 and the connecting arm 9; the rotating member 7 is provided with a connecting hole, and the clamping member 4 is connected with the rotating member 7 through the connecting hole; the bottom end of the clamping component 4 is provided with a clamping part which is connected with the belt-shaped ceiling 5.

The sliding member 6 can freely slide along the main keel 2 and is fixed at any position by the first locking device 8. The rotating member 7, which is rotatably connected to the connecting arm 9, provides a degree of freedom of rotation and is fixed at any angle by the second locking means 10. In addition, the clamping component 4 can be stretched in any length in the connecting hole, and the three-dimensional mounting assembly 3 can be adjusted in three degrees of freedom. The main keels 2 can be arranged under the hoisting assembly 1 in an adjustable density degree according to requirements so as to meet the arrangement requirements of hoisting points and calculate a degree of freedom. Therefore, the hoisting structure of the invention can be matched with the modeling requirement of the strip-shaped ceiling 5 in four degrees of freedom. Especially, the rotating degree of freedom of the rotating member 7 can drive the strip-shaped ceiling 5 to twist, and the shape is more variable.

Preferably, the top side of the main keel 2 is provided with a top groove 11 extending along the axial direction, and two sides of the main keel 2 are provided with side grooves 12 extending along the axial direction; the sliding component 6 is provided with a positioning flange 13 matched with the side groove 12, the positioning flange 13 is embedded in the side groove 12 and is matched with the side groove in a sliding way, and the first locking device 8 is matched with the top groove 11.

The main keel 2 is preferably formed from a profile to facilitate the machining of the top channel 11 and side channels 12, and the slide member 6 is suitably formed from a casting. The sliding member 6 may be an integrally formed component or a separately assembled component.

Referring to fig. 3 in detail, if the sliding member 6 is a split assembly structure, it is preferable that the sliding member 6 includes an upper member 14 and a lower member 15 which are symmetrically disposed; the upper member 14 and the lower member 15 are semi-annular, the positioning flange 13 is fixedly arranged at the inner side of the end part of the semi-annular in a protruding way, the semi-annular periphery of the upper member 14 and the lower member 15 is respectively provided with an upper connecting arm 16 and a lower connecting arm 17 in a protruding way, and the upper connecting arm 16 and the lower connecting arm 17 are spliced to form the complete connecting arm 9; the upper connecting arm 16 and the lower connecting arm 17 are respectively provided with an upper half shaft hole and a lower half shaft hole at the joint, the upper half shaft hole and the lower half shaft hole are spliced to form a complete shaft hole, the rotating member 7 is fixedly provided with a rotating shaft 18, and the rotating shaft 18 is inserted into the shaft hole so that the rotating member 7 can rotate around the rotating shaft 18; the second locking means 10 is arranged between the connecting arm 9 and the spindle 18.

In cooperation with the limiting head, a limiting head 19 protruding in the radial direction is arranged at the end of the rotating shaft 18, limiting grooves 20 matched with the limiting head 19 are respectively arranged at the inner ends of the upper half shaft hole and the lower half shaft hole, and the limiting head 19 is sleeved with the limiting grooves 20 when the rotating shaft 18 is inserted into the shaft holes.

The split sliding member 6 is matched with the side groove 12 of the main keel 2, and has a very superior characteristic that the installation is very convenient.

The slide member 6 is divided into two parts, and becomes the upper member 14 and the lower member 15, and the link arm 9 is also divided into two parts, and becomes a structure detachable along the middle part, and the rotary member 7 is easily attached to the link arm 9. In fact, the upper member 14 and the lower member 15 can be manufactured as two parts having the same shape and structure by using the same mold. If the rotating shaft 18 of the rotating member 7 has no limiting head 19, direct insertion can be realized during installation, but the limiting head 19 can limit the rotating member 7 not to be loosened outwards, so that the structure is an effective stable structure. The rotary member 7 with the stopper 19 is connected by the upper member 14 and the lower member 15, and the structure such as a positioning pin can be omitted.

Meanwhile, after the sliding member 6 is divided into the upper member 14 and the lower member 15, the sliding member can be connected with the main keel 2 through the side groove 12 independently. In the sliding process, as long as the upper member 14 or the lower member 15 is dragged, the rotating shaft 18 of the rotating member 7 drives the other member to synchronously slide, and similarly, as long as the upper member 14 is fixed by the first locking device 8, the whole combined three-dimensional mounting assembly 3 is completely fixed on the main keel 2.

The installation sequence is that the rotating shaft 18 of the rotating member 7 is firstly placed in the lower half shaft hole of the lower member 15, then the upper member 14 is spliced on the lower member 15, the upper connecting arm 16 and the lower connecting arm 17 are jointed to fix the rotating shaft 18 of the rotating member 7, and then the spliced sliding member 6 is sleeved on the main keel 2. The whole sliding member 6 cannot be separated due to the main runner 2 side groove 12 and the positioning flange 13 of the sliding member 6, which in turn prevents the rotary member 7 with the stopper 19 from being released. The four parts are combined together in this way, and any screw is not used for assisting installation, so that the installation is convenient.

Preferably, the first locking device 8 is a first locking bolt, the top side of the sliding member 6 is provided with a first threaded hole matched with the first locking bolt, and the first locking bolt is in threaded connection with the first threaded hole and acts on the top side of the main keel 2. The first locking bolt can be a butterfly bolt to facilitate manual operation.

Similarly, the second locking device 10 is preferably a second locking bolt, and the connecting arm 9 is provided with a second threaded hole opposite to the rotating member 7, and the second locking bolt is in threaded connection with the second threaded hole and acts on the rotating member 7. The second locking bolt can adopt a butterfly bolt to facilitate manual operation.

Referring to fig. 4 to 6, specifically, the clamping member 4 is preferably a supporting rod, the clamping portion disposed at the bottom end of the supporting rod is an axially extending abdicating groove 21, and two sides of the abdicating groove 21 are provided with transversely penetrating mounting holes; the top edge of the strip-shaped ceiling 5 is inserted into the receding groove 21.

It should be noted that the abdicating groove 21 and the mounting hole may be directly machined on an integrally machined support rod, or may be integrated on another separate component and then fixedly connected with the bottom end of the support rod, and the action principles of the two components are completely identical.

In order to achieve any three-dimensional contouring of the belt ceiling 5, it must be provided with a mating connection structure to the three-dimensional mounting assembly 3 to cooperate therewith. There are three preferred options for this connection structure.

Referring to fig. 4 in detail, in the present embodiment, preferably, the strip ceiling 5 is provided with through holes (not shown) along the top edge for matching with the mounting holes, and the mounting holes are connected with any through hole by pins 25, so that the strip ceiling 5 is twisted in any arc.

This is a simple connection scheme, and it is only necessary to directly process multiple groups of through holes on the strip-shaped ceiling 5. Different twisting shapes can be theoretically presented as long as the three-dimensional mounting component 3 is adjusted and the through holes at proper positions are selected to be connected with the clamping component 4. However, the arrangement of the through holes is equivalent to having a shift concept, and in consideration of the strength of the material of the strip ceiling 5, the through holes cannot be arranged too densely, so that the adjustment of the configuration is limited.

With particular reference to fig. 1, for a hoist assembly 1, the hoist assembly 1 may include a boom 26; the main keel 2 is fixedly hung at the bottom end of the hanging rod 26. This solution is suitable for simple hoisting.

With particular reference to fig. 2, or as another preference, the lifting assembly 1 comprises a hanger bar 26, an upper level hanger, an upper level keel 27 and a lower level hanger 28; the upper keel 27 is hung below the hanger rod 26 through an upper hanging weight; the main keel 2 is hung below the upper keel 27 through the lower layer hanging weight 28, and the main keel 2 and the upper keel 27 are arranged in a crossed mode. The double-layer keel structure can enable the main keels 2 to be arranged along any density degree and serve as a fourth degree of freedom. The upper layer hanging weight can also be directly replaced by the nut.

Example two

The only difference between this embodiment and the first embodiment is the connecting structure of the belt-shaped ceiling 5 and the clamping member 4.

Referring to fig. 5, in the present embodiment, preferably, the strip-shaped ceiling 5 is provided with a flexible connecting strip 22 along the top edge, the inside of the relief groove 21 is provided with a fitting groove that fits the connecting strip 22, the connecting strip 22 is clamped in the fitting groove, a fastening bolt 23 is screwed to the mounting hole, and the fastening bolt 23 acts on the connecting strip 22 or the strip-shaped ceiling 5 to make the strip-shaped ceiling 5 assume a shape of any twist.

Compared with the scheme of the first embodiment, the connecting belt 22 has no shift concept of a through hole, so that the connection between the strip-shaped ceiling 5 and the clamping component 4 is not limited when the modeling is adjusted. The connecting band 22 is made of flexible material, and can be bent and twisted at will to match the shape of the strip-shaped ceiling 5. In addition, the tabling groove can be matched with the connecting belt 22, and has a certain supporting and loading effect on the connecting belt, so that the mechanical structure is more scientific.

EXAMPLE III

The present embodiment is similar to the second embodiment, and the only difference from the first embodiment is also the connection structure between the belt-shaped ceiling 5 and the clamping member 4.

Referring to fig. 6, preferably, in the present embodiment, the belt-shaped ceiling 5 is provided with a connecting chain 24 along the top edge, and the connecting chain 24 is formed by fastening a plurality of connecting rings, so that the connecting chain 24 can be bent and twisted arbitrarily; the inside of the recess groove 21 is provided with a fitting groove which is fitted with the link chain 24, the link chain 24 is fitted in the fitting groove, the mounting hole is screwed with the fastening bolt 23, and the fastening bolt 23 acts on the link chain 24 or the belt-shaped ceiling 5 to give the belt-shaped ceiling 5 a shape of arbitrary twist.

Compared with the first embodiment, the connecting chain 24 of the present embodiment also has no gear concept, and the belt-shaped ceiling 5 can be adjusted freely. However, compared with the connecting belt 22 of the second embodiment, each connecting ring in the connecting chain 24 is a rigid component, which is less prone to damage and has a longer service life.

Other technical features of the second embodiment and the third embodiment are completely the same as those of the first embodiment, and are not described herein again.

The invention provides a three-dimensional strip-shaped suspended ceiling, which applies a special three-dimensional mounting component 3. The three-dimensional mounting assembly 3 has a plurality of degrees of freedom, in particular the rotational degrees of freedom of the rotating member 7, which enables the strip ceiling 5 to have not only a curved shape but even a three-dimensional twisted shape. And the three-dimensional mounting component 3 has simple structure, easy production, especially convenient installation, and does not need to use a screw during combination. And the connection structure of the banded ceiling 5 and the clamping member 4 has three optional implementation schemes, can adapt to any three-dimensional shape, and has stable structure and scientific and reasonable structure.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
