Description

Technical Field

[0001] The utility model relates to the technical field of integrated ceiling decoration equipment, and more specifically, to a hoisting profile assembly and a hoisting lamp. Background Technique

[0002] As the top surface of the interior of a building, the ceiling can optimize the indoor environment by installing chandeliers, ceiling fans, etc. However, directly installing electrical appliances on the ceiling will not only affect the beauty of the indoor environment, but also cause cracks and damage to the ceiling in the long run, which will have an impact on people's lives. Therefore, the integrated ceiling came into being. By combining metal square plates and electrical appliances, more functions such as heating, lighting, and ventilation can be completed. With its beautiful appearance, simple installation, flexible layout, and convenient maintenance, the integrated ceiling has become the mainstream in indoor decoration.

[0003] However, in the hoisting profile assembly used, basically linear components are currently used for assembly. During assembly, the contact area between the components is relatively large, the assembly process is not smooth enough, and it is easy to produce extrusion deformation. The surface of the components is also severely worn, resulting in a short service life of the hoisting profile. Moreover, such components cannot be adjusted according to the actual installation and indoor conditions, and the flexibility is not strong. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the above-mentioned technical deficiencies and provide a hoisting profile assembly and a hoisting lamp with a smoother assembly process, less prone to deformation, and adjustable according to actual conditions.

[0005] A hoisting profile assembly includes: a clamping member and a clamping fixture;

[0006] The clamping member includes: a top piece provided at the top, and two clamping pieces. A first clamping cavity is formed between the clamping pieces, and a concave supporting portion is provided at the lower part of the clamping pieces;

[0007] The clamping fixture is sleeved in the first clamping cavity and includes: a clamping piece extending upward; a clamping piece extending downward. A second clamping cavity is formed between the clamping pieces, and a concave joint cavity is provided on the clamping piece, and the joint cavity matches the supporting portion.

[0008] Since the clamping piece and the clamping fixture are in a state of extrusion and friction at the supporting portion and the joint cavity during the assembly process, the assembly cannot be carried out very smoothly. After long-term use, the clamping piece may be deformed, and its surface layer will also be damaged due to friction.

[0009] By setting the concave supporting part and the concave engaging cavity to match each other, the supporting part will not squeeze the engaging cavity during assembly, which can prevent the clamping piece from deforming. The contact area between the two becomes smaller, and only the concave part of the supporting part contacts the bottom of the concave engaging cavity. Therefore, the assembly of the clamping piece and the clamping part is smoother and more convenient.

[0010] By changing the structures of the clamping piece and the clamping part, the stability of the component is improved, the average lifespan of the component is extended, and when installing other components such as a light bar in the second clamping cavity, it can be more smooth and convenient, avoiding damaging the surface layer of the clamping part during maintenance.

[0011] The top piece includes a flat plate section and extension sections arranged on both sides of the flat plate section. Since the top piece is connected to the clamping piece, the top piece will also be subject to corresponding forces. To ensure the clamping force of the clamping piece, it is necessary to increase the lateral length of the top piece. However, increasing the length of the extension section also increases the possibility of fracture. Therefore, the extension section is inclined, with the side close to the flat plate section being lower and the side far from the flat plate section being higher, which helps to better adjust the force on the top piece. The inclined setting can increase the length of the extension section without increasing the lateral dimension of the entire top piece, improving the force on the extension section and reducing the risk of fracture.

[0012] The clamping piece includes: a first arc section that is concave towards the middle, with one end connected to the top piece;

[0013] a second arc section that protrudes outward, with one end of the second arc section connected to the first arc section and the other end connected to the supporting part.

[0014] Through the setting of the first arc section that is concave towards the middle and the second arc section that protrudes outward, the force on the clamping piece can be further optimized, the structure of the clamping piece is more stable, the arc section setting also makes the clamping piece have better elasticity when opening and is not easily deformed, and the second arc section that protrudes outward can provide more accommodation space.

[0015] A first assembly cavity is formed inside the first arc section. When assembling the component, it is necessary to adjust the relative positions of the clamping piece and the clamping part according to the actual situation. A number of protruding pieces that cooperate with the clamping pieces are provided in the first assembly cavity. One end of the protruding piece is connected to the first arc section, and the other end extends towards the middle.

[0016] By setting the first arc section as an arc section that is concave towards the middle, the formed first assembly cavity has a large space, which is convenient for installation. And the arc length is longer than that of a straight line type, so a number of protruding pieces that cooperate with the clamping pieces can be set. According to the actual situation, it is determined which group of protruding pieces the clamping piece is assembled with, and the relative positions of the clamping piece and the clamping part are adjusted, so as to adapt to different situations and the design is more flexible.

[0017] There are two sets of the protruding pieces. Each set includes two protruding pieces that are at the same distance from the top piece and are respectively connected to the two clamping pieces. The protruding pieces are inclined, and the side closer to the connected clamping piece is higher than the other side.

[0018] The protruding pieces need to support the clamping piece. If the protruding pieces are only arranged at one end of the clamping piece, the clamping piece will become inclined, and the force on the clamping piece will be uneven, resulting in serious wear of the component and the structure becoming unstable. Therefore, each set of the protruding pieces is arranged in pairs, and the clamping piece can be supported from both sides of the clamping piece. And the structure that slopes downward from the outside to the inside can make the disassembly and assembly not easy to cause wear and is more convenient to use.

[0019] The supporting part is arranged in an inwardly concave structure. Therefore, the supporting part includes an inwardly concave arc section, a straight section, and a hook-shaped arc section that are connected in sequence. The inwardly concave arc section is connected to the second arc section. The two clamping pieces are symmetrically arranged, and the supporting parts respectively connected to the clamping pieces are symmetrically arranged.

[0020] The lower edge of the inwardly concave part of the inwardly concave arc section and the joint cavity is the main contact part during assembly. The design of the inwardly concave arc section can form better line contact. Its inwardly concave structure plays an upper supporting and positioning role in the joint cavity, facilitating the assembly of the clamping part and the clamping piece. Since the contact part area is small, it can reduce wear and deformation during assembly and extend the service life of the component. When cooperating with other plug-in parts subsequently, the design of the inwardly concave arc section can form a guiding structure with its arc, making it more convenient for other plug-in parts to be inserted.

[0021] The straight section and the hook-shaped arc section are arranged outward, causing the clamping piece to extend outward. The outward extension structure provides sufficient clamping force and can meet more functional expansion and requirements, making the component structure compact and effective.

[0022] The part corresponding to the protruding piece for assembly and insertion is the clamping piece, which includes a vertical connecting section and a horizontal and inclined hanging section. The clamping pieces are arranged in pairs, and the hanging sections face the two clamping pieces respectively. The inclined setting of the clamping piece is the same as that of the protruding piece, which can better complete the insertion. The clamping piece can be selectively assembled on which protruding piece, so as to adjust the relative position of the clamping part and the clamping piece, so as to adapt to different actual situations.

[0023] Since the clamping piece is provided with the upwardly extending clamping piece and the downwardly extending clamping piece, a horizontally arranged substrate is required for connection, making the structure of the clamping piece stable. The clamping piece also needs to form the second clamping cavity for completing the fixed installation with other components.

[0024] Therefore, the clamping member further includes a horizontal substrate. The lower end of the clamping piece is connected to the middle of the horizontal substrate, and the upper ends of the clamping pieces are connected to both ends of the horizontal substrate, making the structure of the clamping member more stable and forming the second clamping cavity.

[0025] On the inner side of the clamping piece, there are clamping protrusions opposite to each other, enabling the second clamping cavity structure to be directly fixed to other components by clamping, making the assembly more convenient. On the other side of the clamping protrusion is a concave portion, that is, the engaging cavity that cooperates with the supporting portion. By providing an inwardly concave structure on the clamping piece, the assembly on both sides of the clamping piece can be made more convenient, less likely to deform and wear, and the structure is more simple and compact.

[0026] Since the structures of most accessories are square structures, the clamping piece is vertically arranged to form a square second clamping cavity structure with the horizontal substrate, which can cooperate with different accessories for use, improving the applicability of the component. The clamping piece includes a vertical downward extension section, a concave section, and a combination section arranged in sequence. The concave section forms an engaging cavity communicating with the outside, and the combination section can cooperate with external accessories to be accessed from the side, enabling the expansion and improvement of the functions of the component.

[0027] Since the external accessory is fixed to the combination section by being accessed from the side, the external accessory may break away from the hoisting profile component due to insufficient fixation, posing a risk of damage. Therefore, the surface of the combination section is provided with convex stripes arranged at intervals, which can provide sufficient friction between the external accessory and the combination section, thereby improving the stability of the overall structure when the accessory is accessed from the side.

[0028] This application also includes a hoisting lamp, comprising: a light strip and a lampshade, and the light strip is enclosed in the second clamping cavity through the lampshade.

[0029] The beneficial effects of the present utility model are as follows: By providing an inwardly concave supporting portion and an engaging cavity, the hoisting profile component cooperates with each other during the assembly process, and the contact area between the clamping member and the clamping piece becomes smaller. This can not only prevent the clamping piece from deforming and suffering from excessive wear, making the assembly process smoother and more stable, but also make the hoisting profile component have better elasticity, a larger accommodation space, and more uniform force;

[0030] The extension portion of the supporting portion and the combination section of the clamping piece can expand more functions of the component. The several groups of protruding pieces provided can adjust the relative positions between the clamping member and the clamping piece to adapt to the actual assembly environment. The hoisting profile component has higher flexibility and applicability, and strong expandability, without being overly restrictive;

[0031] Through the structural design details such as the inclined setting of the top sheet extension section and the convex pattern of the clamping sheet, the stability of the hoisting profile assembly is effectively improved, and it is safer during actual use. Description of the Drawings

Detailed Embodiments

[0038] To make the objectives, technical solutions and advantages of the present invention clearer, the following will further describe the embodiments of the present invention in detail with reference to the drawings:

[0039] Embodiment 1: Refer to Figure 1

[0040] The present utility model provides a hoisting profile assembly, which includes two parts, a clamping member 100 and a clamping member 200, and the structure of the hoisting profile assembly is as Figure 1 shown.

[0041] The clamping member 100 includes: a top sheet 110 provided at the top, and two clamping sheets 120. A first clamping cavity is formed between the clamping sheets 120, and a concave supporting portion 130 is provided at the lower part of the clamping sheets 120;

[0042] The clamping member 200 is sleeved in the first clamping cavity and includes: a latching piece 210 extending upward; a clamping piece 220 extending downward, a second clamping cavity is formed between the clamping pieces 220, and a concave engaging cavity 230 is provided on the clamping piece 220, and the engaging cavity 230 matches the supporting portion 130.

[0043] For the assembly of the hoisting profile assembly, the clamping member 200 needs to be sleeved and assembled into the clamping member 100. During the assembly process, a part of the clamping piece 120 and the clamping piece 220 will always be in a state of extrusion and friction. The linear structure will not only cause the assembly to jam, but also easily lead to the deformation and surface damage of the hoisting profile assembly after long-term use. Therefore, the hoisting profile assembly is designed as a concave structure, which is composed of the concave supporting portion 130 at the lower part of the clamping piece 120 and the concave engaging cavity 230 on the clamping piece 220. The concave structure can play a good guiding role, making the component assembly more smooth and reducing the contact area between the clamping member 200 and the clamping member 100, that is, only the part of the concave structure comes into contact, the pressure is reduced accordingly, so it is not easy to deform due to extrusion and will not damage the surface of the component on a large scale, improving the stability of the component structure.

[0044] Example 2: Refer to Figure 2

[0045] Compared with Example 1, the difference is that the top piece 110 further includes a flat plate section 111 and extension sections 112 provided on both sides of the flat plate section. The extension sections 112 are inclined, with the side close to the flat plate section 111 being lower and the side far from the flat plate section 111 being higher.

[0046] For the assembly of the hoisting profile assembly, the clamping member 200 needs to be sleeved and assembled into the clamping member 100, and the clamping piece 120 needs to completely clamp the latching piece 210, otherwise there is a risk of the clamping member falling off. To ensure the clamping force of the clamping piece 120, it is necessary to increase the lateral length of the top piece 110. However, increasing the length of the extension section 112 of the top piece 110 will increase the possibility of the extension section 112 breaking, and at the same time, the increase in the lateral length may also affect the installation of other components, which is not conducive to subsequent installation and dimensional unity.

[0047] Therefore, in this application, the extension section 112 is inclined, with the side close to the flat plate section 111 being lower and the side far from the flat plate section 111 being higher, which helps to better adjust the force on the top piece 110, ensure that the clamping piece 120 can clamp the latching piece 210. The extension section 112 can appropriately increase the length through the inclined setting, and at the same time, it will not increase the lateral dimension of the entire top piece 110, improve the force on the extension section 112, and reduce the risk of fracture.

[0048] Compared with Example 1, the difference also lies in that the clamping plate 120 also includes: a first arc segment 121 recessed toward the middle, one end of which is connected to the top plate 110, and a second arc segment 122 protruding toward the outside, one end of the second arc segment 122 is connected to the first arc segment 121, and the other end is connected to the supporting portion 130.

[0049] In order to further improve and optimize the stability and clamping force of the clamping sheet 120, the clamping sheet 120 is set to have a structure with three arc segments, wherein the first arc segment 121 that is recessed toward the middle allows the clamping sheet 120 to clamp the clamping sheet 210 under a more stable and uniform force, and the second arc segment 122 is set to a structure that protrudes toward the outside, which can provide more accommodation space, making the assembly of the component more flexible and adaptable. The supporting portion 130 is recessed toward the middle to provide guidance and support for the assembly, and in the long-term use of the component, it is ensured that the component is not easily deformed and worn. The clamping sheet 120 is set with three arc segments to optimize the force of the clamping sheet 120, so that the structure of the clamping sheet 120 is more stable, the elasticity of opening is better, it is not easy to deform, and the accommodation space is increased to improve the adaptability of the component.

[0050] Compared with Example 1, the difference lies in that a first assembly cavity is formed on the inner side of the first arc segment 121, and a plurality of protruding pieces 123 cooperating with the snap-in pieces 210 are arranged in the first assembly cavity, and one end of the protruding piece 123 is connected to the first arc segment, and the other end extends toward the middle.

[0051] By setting the first arc segment 121 as an arc segment concave toward the middle, the space of the first assembly cavity is large, which is convenient for the installation of the component. Since it is not enough to clamp the clamping piece 210 by the clamping piece 120 set by the arc segment, the cooperation of the protruding piece 123 is also required to clamp the clamping piece 210 on the protruding piece 123, so as to further ensure the stability of the hanging profile component. The arc length of the first arc segment 121 is longer than that of the straight type, and the force is more uniform. Therefore, several groups of protruding pieces 123 cooperating with the clamping piece 210 can be set, and the clamping piece 210 is determined according to the actual situation. Which group of protruding pieces 123 is assembled, adjust the relative positions of the clamping piece 100 and the clamping piece 200, so as to adapt to different actual installation conditions, and the design is more flexible.

[0052] Compared with Example 1, the difference lies in that the protruding pieces 123 are divided into two groups, each group includes two protruding pieces 123 which are at the same distance from the top piece 110 and are respectively connected to two clamping pieces 120, and the protruding pieces 123 are arranged at an angle and one side close to the connected clamping piece 120 is higher than the other side.

[0053] Due to the dimensional limitations of the hoisting profile, two sets of symmetric protruding pieces 123 are provided in the first arc segment 121 of this application. The protruding pieces 123 must be symmetrically arranged because the protruding pieces 123 need to support the clamping pieces 210. If they are not symmetrically arranged, the forces on the first arc segment 121 and the protruding pieces 123 will be in an unbalanced state, and the clamping pieces 210 will also tilt, resulting in uneven stress on the entire assembly and the structure becoming unstable. If other components such as a light strip are connected in this state, it is very easy to accelerate the damage of the assembly. Therefore, each group of the protruding pieces 123 is arranged in pairs, which can support the clamping pieces 210 from both sides of the clamping piece 120. Moreover, the protruding pieces 123 are arranged in a structure that slopes downward from the outside to the inside, which can prevent wear during disassembly and assembly and is more convenient to use.

[0054] Compared with Embodiment 1, the difference is also that the supporting part 130 further includes a concave arc segment 131, a straight segment 132, and a hook-shaped arc segment 133 that are connected in sequence. The concave arc segment 131 is connected to the second arc segment 122, and the two clamping pieces 120 are symmetrically arranged, and the supporting parts 130 respectively connected to the clamping pieces 120 are symmetrically arranged.

[0055] The lower edge of the concave part of the concave arc segment 131 and the engaging cavity 230 is the main contact part during assembly. The design of the concave arc segment can form better line contact. Its concave structure plays an upper support and positioning role in the engaging cavity 230, facilitating the assembly of the clamping part 100 and the clamping part 200. Since the contact area of the contact part is small, wear and deformation during assembly can be reduced, and the service life of the assembly can be extended. When cooperating with other plug-in parts subsequently, the design of the concave arc segment can utilize its arc to form a guiding structure, making it more convenient for other plug-in parts to be inserted.

[0056] The straight segment 132 and the hook-shaped arc segment 133 are arranged outward, causing the clamping piece 120 to extend outward. The outward extension structure provides sufficient clamping force and can meet more function expansion and requirements, making the assembly structure compact and effective.

[0057] Embodiment 3: Refer to Figure 3

[0058] Compared with Embodiment 1, the difference is that the clamping piece 210 includes a vertical connecting segment 211 and a horizontally and obliquely arranged hanging segment 212. The clamping pieces 210 are arranged in pairs, and the hanging segments 212 face the two clamping pieces 120 respectively.

[0059] For the assembly of the hoisting profile component, the clamping part 200 needs to be sleeved and assembled into the clamping part 100. Among them, the clamping piece 210 is assembled and inserted into the clamping piece 120. Its hanging section 212 is arranged obliquely in the same direction as the protruding piece 123, which can facilitate the insertion better. The hanging sections 212 are also arranged in pairs to ensure uniform force. The hanging section 212 is selectively hooked on a certain group of protruding pieces 123 to adjust the relative positions of the clamping part 100 and the clamping part 200 to complete the insertion, so as to adapt to different actual situations.

[0060] Compared with Embodiment 1, the difference also lies in that the clamping part 200 further includes a horizontal substrate 240. The lower end of the clamping piece 210 is connected to the middle of the horizontal substrate 240. The upper ends of the clamping pieces 220 are connected to both ends of the horizontal substrate 240. Oppositely-positioned clamping protrusions are provided on the inner side of the clamping piece 220.

[0061] Since the clamping part 200 is provided with the upward-extending clamping piece 210 and the downward-extending clamping piece 220, a horizontally arranged substrate is required for connection, making the structure of the clamping part 200 stable. The clamping part 200 also needs to form the second clamping cavity for completing the fixed installation with other components. Therefore, a horizontal substrate 240 is provided on the clamping part 200. The lower end of the clamping piece 210 is connected to the middle of the horizontal substrate 240. The upper ends of the clamping pieces 220 are connected to both ends of the horizontal substrate 240, making the structure of the clamping part 200 more stable and forming the second clamping cavity.

[0062] Oppositely-positioned clamping protrusions are provided on the inner side of the clamping piece 220, enabling the second clamping cavity structure to be directly fixed to other components by clamping, making the assembly more convenient. The other side of the clamping protrusion is a concave part, that is, the engaging cavity that cooperates with the supporting part 130. By providing an inwardly concave structure on the clamping piece 220, the assembly on both sides of the clamping piece 220 can be made more convenient, not easily deformed and worn, and the structure is simpler and more compact.

[0063] Compared with Embodiment 1, the difference also lies in that the clamping piece 220 is vertically arranged and includes a vertically downward-extending section 221, a recessed section 222, and a combined section 223 arranged in sequence. The recessed section forms an engaging cavity 230 communicating with the outside. The surface of the combined section is provided with convex stripes arranged at intervals.

[0064] Since the structures of most of the accessories are square structures, the clamping piece 220 is vertically arranged to form a square second clamping cavity structure with the horizontal substrate 240, which can be used in cooperation with different accessories and improve the applicability of the assembly. The clamping piece includes a vertical downward extension section 221, a recessed section 222 and a combined section 223 arranged in sequence. The recessed section 221 forms a joint cavity 230 communicating with the outside. The combined section 223 can cooperate with external accessories to be accessed from the side, and the functions of the assembly can be expanded and improved.

[0065] Since the external accessories are fixed to the combined section 223 by being accessed from the side, the external accessories may break away from the hoisting profile assembly due to insecure fixation, posing a risk of damage. Therefore, the surface of the combined section 223 is provided with convex stripes arranged at intervals, which can provide sufficient friction between the external accessories and the combined section, thereby improving the stability of the overall structure when the accessories are accessed from the side.

[0066] Example 4: Refer to Figure 4

[0067] Compared with the above embodiments, the difference is that this application also provides a hoisting lamp, which includes: a light strip and a lamp shade 300, and a hoisting profile assembly described in the above embodiments. The light strip is enclosed in the second clamping cavity through the lamp shade 300.
