Description

Technical Field

[0001] The utility model relates to the technical field of lamp installation, in particular to a surface-mounted conversion frame. Background Art

[0002] In the installation of some lamps, a surface-mounted conversion frame is required. Generally, the surface-mounted conversion frame is fixed and formed by multiple splicing parts, such as metal profiles as splicing parts, and multiple splicing parts are fixed by screws to form a rectangular or other shaped frame. The fixing method using screws is more troublesome and reduces the assembly efficiency. In response to this, screw-free surface-mounted frames have appeared on the market. For example, the patent document with authorization announcement number CN208365310U discloses a solution for fixing the profiles on both sides by means of buckles. In this solution, convex ridges need to be formed on the sides of the profiles, and slots need to be formed on the convex ridges to dock with the buckles. The profile molding is difficult and needs to be improved. Utility Model Content

[0003] In order to solve at least one of the above technical defects, the utility model provides the following technical solutions:

[0004] The present application document discloses a surface-mounted conversion frame, including a frame body, wherein the frame body includes splicing pieces and a snap mechanism, wherein the splicing pieces at adjacent two sides are connected by the snap mechanism, wherein the snap mechanism includes a first connecting piece and a second connecting piece, wherein the first connecting piece includes two connected snap-fitting portions, and the second connecting piece is fixed at the end of the splicing piece, and each snap-fitting portion is snap-connected to the second connecting piece on the corresponding side splicing piece.

[0005] In the present solution, the structure is improved, the second connecting piece is formed independently from the splicing piece, and then fixed at the end of the splicing piece. When the frame is assembled, the second connecting piece is connected to the first connecting piece at the end of the splicing piece through a snap connection to fix the splicing pieces on both sides as a whole. The second connecting piece and the splicing piece are formed independently, which helps to reduce the difficulty of forming the splicing piece.

[0006] During assembly, taking a rectangular frame as an example, a second connecting piece is fixed at the end of the splicing piece, and the splicing pieces at the front and rear sides are connected with the splicing pieces at the left and right sides through a snap mechanism to form a frame, without the need for fasteners such as screws, thereby improving assembly efficiency.

[0007] For the splicing parts, such as metal profiles, wood or plastic plates, etc., the splicing parts form the main structure of the frame.

[0008] Furthermore, the snap-on portion includes a substrate and a snap-on member. The substrate is plugged into a slot formed on the second connector. The snap-on member forms a snap-on connection with a slot provided on the second connector. The substrate is plugged into the slot of the second connector. The snap-on fixation of the snap-on member and the second connector helps to improve the stability of the connection. For the connection of the snap-on member, such as directly fixing it on an adjacent substrate, or fixing it on another substrate in the first connector, the position of the snap-on member can be basically at the front, that is, between the two substrates, or at the back of the substrate, or at the upper or lower position of the substrate. The shape of the snap-on member can be freely selected according to common structures on the market.

[0009] Furthermore, a slot that cooperates with the snap-fit ​​component is provided at the slot wall of the slot, which helps to simplify the structure and improve the stability of the connection.

[0010] Furthermore, a notch is provided at the top wall or the bottom wall of the slot and a card slot is provided at the side wall of the notch. The purpose of adding the notch is to facilitate separation of the fastener from the card slot at the notch for later disassembly.

[0011] Furthermore, the slot of the second connecting member extends along the length direction of the splicing piece, and a slot is formed along the width at the slot wall of the slot to limit the position of the slot direction machine slot. The insertion of the substrate into the slot under this configuration helps to limit the separation in the width direction of the splicing piece. The snap-on connection between the snap member and the slot walls on both sides of the slot helps to limit the separation in the length direction of the splicing piece, and the connection structure is more stable.

[0012] Furthermore, the two substrates in the two connected clamping parts are connected at the ends, the clamping member is located between the two substrates, the two clamping members are connected at the ends and fixed at the connection between the two substrates, and this configuration facilitates the integral molding of the first connector, such as injection molding.

[0013] Furthermore, the two connected clamping parts are vertically connected. Currently, the most common frame on the market is a rectangular frame, and the vertical connection of the clamping parts facilitates the assembly of this type of frame.

[0014] Furthermore, the snap fastener is L-shaped, the horizontal end of the snap fastener is connected to the base plate, and the front end surface of the longitudinal end of the snap fastener is inclined, with a simple configuration and convenient molding.

[0015] Furthermore, it also includes a decorative block. The decorative block is arranged at the connection between the two clamping parts. The end faces of two adjacent assembling pieces abut against the side faces of the decorative block. The decorative block fills the gap between the two assembling pieces to improve the aesthetics.

[0016] Furthermore, the splicing piece is in the shape of a groove plate, and a second connecting piece is arranged at the inner end of the groove cavity of the splicing piece.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] 1. The utility model has an improved structure, in which the second connecting piece and the splicing piece in the buckle mechanism are formed independently, which reduces the difficulty of forming the splicing piece. The splicing pieces are fixed by the buckle mechanism without the need for screws and other structures, which improves assembly efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0026] Example 1

[0027] like Figure 1 As shown, in this example, the surface-mounted conversion frame includes a frame body, which is a common rectangular frame body in this example. The frame body includes a splicing piece 3 and a buckle mechanism. The splicing piece is also a common groove plate-shaped metal profile. The splicing pieces 3 on the adjacent sides of the frame are fixed together by a buckle mechanism, such as Figure 1 In the state shown, snap-fit ​​mechanisms are arranged at the four corners, thereby connecting and fixing adjacent splicing parts to form a rectangular frame.

[0028] In this example, the snap mechanism includes a first connector 1 and a second connector 2, wherein the first connector 1 includes two connected snap-in portions 10. Since a rectangular frame is used for display, the two connected snap-in portions are perpendicular to each other. The second connector 2 is fixed at the end of the groove of the splicing piece 3, and the second connector is fixed by welding, gluing, etc. During assembly, each snap-in portion 10 in the first connector 1 is snap-connected with the second connector 2 on the corresponding side splicing piece 3, so that the splicing pieces on both sides are fixed as a whole. The second connector is formed independently from the splicing piece, which reduces the difficulty of forming the splicing piece.

[0029] In this example, the clamping portion 10 in the first connecting member 1 includes a base plate 101 and a clamping member 102. The base plate 101 is in the shape of a common rectangular plate. Figure 1 , Figure 2 As shown, the two substrates 101 are connected at the ends and are vertical, and the buckle 102 is located at the front of the substrate 101, that is, between the two substrates 101. A slot 21 is formed on the second connecting member 2, and the slot is plugged with the substrate. A slot 22 that cooperates with the buckle is formed at the slot wall of the slot 21. When the substrate is inserted into the slot, the buckle is buckled with the slot wall to form a buckle connection. A rib 103 can also be formed at the connection between the two substrates 101 to improve the structural strength.

[0030] like Figure 1 , Figure 2 , Figure 3 As shown, the configuration of the second connecting member can be selected according to needs, such as a circular, rectangular strip-shaped or other irregular configurations, etc., which can be selected according to needs. In this example, only the strip-shaped configuration is shown. A slot 21 is formed in the middle position of the second connecting member 2, and the slot 21 extends along the length direction of the splicing member 3. The slot 21 is recessed along the width direction at the wall of the slot 21 to form a slot, namely a card slot 22, to cooperate with the snap-on member.

[0031] The buckle 102 can also be selected into a specific configuration according to the needs. In this example, it is shown in a common L-shape. If the horizontal end of the buckle 102 is fixed to the adjacent substrate, Figure 1 , Figure 2 The horizontal ends of the two fasteners converge and are fixed at the end connection of the two substrates 101. This configuration facilitates the one-piece injection molding of the first connector. The hook end (i.e., the longitudinal end) of the fastener 102 faces the two sides of the substrate 101. During the process of inserting the substrate into the slot, the hook end of the fastener 102 is inserted into the slot 22, and the separation of the splicing parts in the length direction is limited by hooking the slot wall, and the insertion of the slot and the substrate limits the separation in the width direction. In addition, it is preferred that the front end surface of the longitudinal end of the fastener is in the shape of an inclined plane, and when plugged in, the inclined plane abuts against the slot wall to offset the fastener, which is convenient for assembly.

[0032] Preferably, a notch 23 is formed on the top wall of the slot 21, and a card slot 22 is formed on the cavity walls on both sides of the notch 23, so that the card connection between the fastener and the card slot is exposed, which facilitates the detachment of the hook end of the fastener from the card slot during subsequent disassembly.

[0033] Of course, the hook end of the fastener can also face other directions, and the corresponding slot can be formed at the slot wall of the slot, or the fastener can be placed on the back side of the substrate, or on both sides, etc., and the slot can be formed at the predetermined position of the second connecting member corresponding to the slot wall or outside the slot.

[0034] In addition, the first connecting member can also be added with a decorative block 11, which is in the shape of a strip. The decorative block 11 is placed at the connection between the two clamping parts. Preferably, the first connecting member is integrally injection molded, and the end faces of the two adjacent splicing pieces 3 are abutted against the side faces of the decorative block 11. The decorative block fills the gap between the two splicing pieces to improve the aesthetics.

[0035] In this solution, when the surface-mounted conversion frame is assembled, adjacent splicing parts can be fixed by a snap-fit ​​mechanism without the need for fasteners such as screws, thereby improving assembly efficiency.

[0036] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of ​​the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
