Based on the above, the invention firstly proposes an inner clamping assembly for mounting a lamp trough, which is characterized in that the inner clamping assembly comprises a metal inner clamping piece for connecting a decorative section bar, a first plastic connecting piece connected to the metal inner clamping piece and a connecting lug for connecting the inner clamping assembly to a building surface, wherein a first clamping structure capable of clamping the decorative section bar is arranged on the metal inner clamping piece; the first plastic connecting piece is provided with a positioning groove extending along the left-right direction, one side wall part of the positioning groove is provided with an elastic buckle, and the metal inner clamping piece avoids an extending space defined by the positioning groove in the left-right direction.

Wherein, the inner card assembly is a bracket body for positioning and supporting the decorative section bar, and also is a bracket body for positioning the illuminant.

Wherein the metal inner clip is a member separate from and connected with the first plastic connector. The metal inner clip may be made of a metal material different from the first plastic connector. In order to optimize the support of the inner clip assembly, the metal inner clip is made of a metal material, so that the first clip structure having excellent mechanical strength can be provided thereon. The metal inner clip is also an intermediate transition piece for connecting the first plastic connecting piece and the decorative profile. In terms of the structural form of the metal inner clamping piece, the metal inner clamping piece can be an integral clamping piece; or the clamping pieces are combined in a split mode, for example, the left clamping piece and the right clamping piece which are arranged in a left-right split mode and comprise metal inner clamping pieces are two parts which are separated from each other.

The first clamping structure is a male connecting structure or a female connecting structure which is used for being connected with a second clamping structure arranged on the decorative section bar in an adapting mode to form clamping connection.

Wherein, correspondingly, the first plastic connector is a component independent of the metal inner clamping piece and connected with the metal inner clamping piece. The first plastic connector may therefore be manufactured from a non-metallic material, such as a plastic material, that is entirely different from the metallic inner clip. In this way, the first plastic connector can be made more lightweight, less expensive, and other functional structures can be easily made thereon. In particular, a positioning groove extending along the left-right direction can be arranged on the first plastic connecting piece, and an elastic buckle is arranged on one side wall part of the positioning groove.

Detailed Description

The structure of the inner card assembly for installing the lamp groove and the simple suspended ceiling lamp groove applying the technical scheme of the invention is further described below with reference to the accompanying drawings.

As shown in fig. 1, the vertical building surface B and the horizontal top surface a enclose a corner portion of the indoor space. The simple suspended ceiling lamp groove is arranged on the vertical building surface B and forms a certain interval distance with the horizontal top surface A. Light emitted by the simple suspended ceiling lamp groove can irradiate on the vertical building surface B and the horizontal top surface A to form wall washing and roof washing effects. The simple ceiling light trough comprises a decorative profile 1 and at least one pair of inner card assemblies 100 for supporting and positioning the decorative profile 1. All of the inside card assemblies 100 are arranged at intervals along the extension direction of the decorative profile 1. The inner clip assembly 100 comprises a metal inner clip 4 for connecting the decorative profile 1, a first plastic connecting piece 3 connected to the metal inner clip 4, and a connecting lug 2 for connecting the inner clip assembly 100 to a building surface, wherein the metal inner clip 4 is provided with a first clamping structure capable of clamping the decorative profile 1. The first plastic connector 3 is provided with a positioning groove 30 extending in the left-right direction, one side wall of the positioning groove 30 is provided with an elastic buckle 33, and the metal inner clamping piece 4 avoids an extending space defined by the positioning groove 30 in the left-right direction. Wherein, the metal inner clamping piece 4 can be an integral clamping piece or a split combined clamping piece. The specific structure of the inner card assembly 100 will be described below by taking the structure of the metal inner card member 4 as a split assembly.

As shown in fig. 2, 3 and 4, the metal inner clip 4 includes a left clip 4a and a right clip 4b which are separated left and right. The left and

right clips

4a and 4b are two separate components from each other, and the left and

right clips

4a and 4b are connected by the first plastic connector 3. Of course, as another embodiment (not shown in the drawings), the left clamping member 4a and the right clamping member 4b may be directly connected to one another through a transition member, and the first plastic connecting member 3 is connected to the metal inner clamping member 4.

As shown in fig. 2, 3 and 4, the left and

right clips

4a and 4b become intermediate transition metal pieces connected to the first plastic connector 3 and the decorative profile 1. The left clamp 4a and the right clamp 4b may have different or the same structure. In this embodiment, the left clamping member 4a and the right clamping member 4b are of a plate-shaped structure formed by stamping and casting, and the left clamping member 4a and the right clamping member 4b have the same structural shape so as to have interchangeability and versatility, so that the manufacturing process of the metal inner clamping member 4 is simplified, and the left clamping member 4a is taken as an example for description.

The left clamping member 4a has two support arms (41 a, 42 a), namely a first left support arm 42a and a second left support arm 41a, wherein the first left support arm 42a and the second left support arm 41a are indirectly connected together through an arc-shaped third arm body 43a in a transitional manner, and an angle of 90 degrees is formed between extension axes of the first left support arm 42a and the second left support arm 41 a. In this way, an included angle space of 90 degrees is formed between the two support arms (41 a, 42 a), so that the decorative section bar 1 with the turning radian more than or equal to pi/2 can be conveniently positioned. Of course, in another embodiment (not shown), the first left arm 42a and the second left arm 41a of the left clip 4a may be disposed at an angle perpendicular to each other, and the first left arm 42a and the second left arm 41a may be directly connected to each other at an angle of 90 °.

The first left arm 42a is provided with a first engagement structure 420a of a male structure, and the second left arm 41a is provided with a first engagement structure 410a of a male structure. The first clamping structures (410 a, 420 a) are male-female connection structures which are used for being connected with second clamping structures (11, 12) of the female structure arranged on the decorative section bar 1 in an adapting mode to form clamping connection. The inner side of the decorative profile 1 is provided with a second clamping structure (11, 12) which is adapted to the first clamping structure (410 a, 420 a), and the inner clamping assembly 100 is accommodated behind the decorative profile 1 and is clamped to the second clamping structure (11, 12) on the decorative profile 1 through the first clamping structure (410 a, 420 a). Similarly, the right clip 4b is also received behind the decorative profile 1 and is clipped to the second clipping structure (11, 12) on the decorative profile 1 by a first clipping structure (420 b, 410 b). The left and

right clips

4a, 4b of the plate-like structure and the metal inner clip 4 assembled therewith do not need to have a left-right extension as large as the decorative profile 1. The metal inner clamping piece 4 can be flexibly arranged at any position or proper position of the decorative section bar 1 according to the length of the decorative section bar 1, and can provide balanced and stable bearing force for the decorative section bar 1. The left and

right clips

4a and 4b are separated from each other in the left and right directions, so that a space is formed therebetween, and the space also serves as a light transmission path. The left and

right clips

4a and 4b are not arranged to block light. After the assembly is completed, the metal inner clamping piece 4 can be hidden by the aid of the decorative profile 1, and the phenomenon that the appearance effect of the suspended ceiling lamp groove is influenced due to the fact that the metal inner clamping piece 4 is exposed is avoided. The decorative profile 1 becomes a lamp trough cover of the lamp trough.

As shown in fig. 2, the first plastic connector 3 connects the left clip member 4a and the right clip member 4b and is located between the left clip member 4a and the right clip member 4 b. The first plastic connecting piece 3 is a transitional connecting piece connected between the left clamping piece 4a and the right clamping piece 4b, so that the left clamping piece 4a and the right clamping piece 4b are connected with each other, and the connection stability and the bearing force between the left clamping piece 4a and the right clamping piece 4b are enhanced. In addition, the first plastic connector 3 is in a split structure with the left and right clamping

members

4a and 4b, so that the first plastic connector 3 may be made of a material completely different from the left and right clamping

members

4a and 4b, for example, a plastic material. In this way, the first plastic connector 3 can be made more lightweight, less expensive, and other functional structures can be easily made thereon. For example, a positioning groove 30 extending in the left-right direction is provided in the first plastic connector 3, an elastic buckle 33 is provided in a lower side wall portion of the positioning groove 30, a pair of buckling

arms

31, 32 are provided in an upper side wall portion, and distal end surfaces 310, 320 of the buckling

arms

31, 32 become distal end surfaces 310, 320 of the first plastic connector 3. The metal inner clip 4 is spaced apart from the extending space in the left-right direction defined by the positioning groove 30. In this way, when it is necessary to mount the lamp 7 in the positioning groove 30 in a long shape and having a length far greater than that of the positioning groove 30 itself, the metal inner clip 4 does not hinder the mounting of the lamp 7 in a long shape, and the lamp 7 can be mounted on the positioning groove 30 and fixed by means of the elastic buckle 33 and the buckling arms (31, 32) in a convenient manner. The first plastic connecting piece 3 is a mounting seat of the lamp 7, so that the corresponding mechanism arranged on the decorative section bar 1 can be reduced, the consumption of the section bar is saved, and the cost is reduced. For example, the decorative profile 1 may omit a lamp mounting groove for positioning a lamp, i.e. the decorative profile 1 is not provided on its inner side with a lamp mounting groove on the decorative profile 1.

As regards the installation position of the first plastic connector 3, it comprises:

first, the first left support arm 42a and the first right support arm 42b are aligned and juxtaposed, and the first plastic connector 3 is located between one end formed by the first left support arm 42a and the first right support arm 42b and one end formed by the second left support arm 41a and the second right support arm 41 b. In this configuration, the inner clip assembly 100 and the decorative profile 1 to which it is attached can be positioned directly onto the upright building surface B by means of the connecting lugs provided on the first left arm 42a or the first right arm 42B, while the second left arm 41a and the second right arm 41B extend below the level of the corner.

Second, the first left arm 42a and the first right arm 42b may be aligned and juxtaposed, the first plastic connector 3 connects the first left arm 42a and the first right arm 42b, and the outer side 421a of the first left arm 42a and the outer side 421b of the first right arm 42b do not protrude from the outer side 300 of the first plastic connector 3. In this way, the inner clip assembly 100 and the decorative profile 1 to which it is connected can be positioned directly onto the upright building surface B by means of the connecting lugs 2 provided on the first plastic connecting piece 3. In addition, in the case where the outer edge 13 of the decorative profile 1 does not protrude beyond the outer side 300 of the first plastic connector 3, the outer side 300 of the first plastic connector 3 may also be a support surface on which the inside card assembly 100 is supported on the upright building surface B. The mounting stability of the inner card assembly 100 and the decorative profile 1 is improved. This second solution is also adopted in this embodiment.

The inner card assembly 100 further includes a second plastic connector 5, and the second plastic connector 5 connects the second left arm 41a and the second right arm 41b. Thus, the first plastic connector 3 and the second plastic connector 5 are separated at both ends of the left clip 4a and the right clip 4 b. The connection stability and the bearing force of the left and right clamping

pieces

4a and 4b can be further enhanced by the second plastic connecting piece 5.

As shown in fig. 1, the decorative profile 1 itself is provided as an exposed decorative surface in the shape of an arc, which is not convenient to saw for cutting 45 ° and which often requires the decorative profile 1 to be leveled by means of a spacer. The use of these blocks often presents processing inconveniences and more importantly, processing inaccuracy. In view of this, the present invention proposes various solutions.

First, the top end surface 50 of the second plastic connector 5 is lower than the top end surface 411a of the second left arm 41a and the top end surface 411b of the second right arm 41b, and the top end surfaces (310, 320) of the first plastic connector 3 are flush with the top end surfaces (411 a, 411 b) of the second left arm 41a and the second right arm 41b.
