Description

Technical Field

[0001] This utility model relates to the field of picture frame strip splicing technology, and more specifically, to a picture frame strip splicing positioning buckle device. Background Technology

[0002] Picture frame splicing refers to the process of connecting multiple frame strips in a specific way to assemble a complete picture frame. Because complete picture frames are large and inconvenient to transport and store, the frame strips are often produced separately and then spliced ​​together when needed to improve transportation efficiency and reduce transportation costs.

[0003] Currently, frame strip splicing is often achieved by connecting right-angle fixing plates, and then fixing the fixing plates and frame strips with bolts to assemble a rectangular frame. Although this connection method is stable, the operation is relatively cumbersome and requires the use of tools. In addition, this connection method also requires precise drilling on the frame strips to ensure that there are no gaps after the frame strips are spliced, which increases the difficulty of production to some extent. Utility Model Content

[0004] This utility model proposes a frame strip splicing and positioning buckle device. By engaging the clamping arm with the toothed plate, the frame strips can be quickly assembled without the need to drill holes in the frame strips, thus reducing the manufacturing difficulty.

[0005] This utility model proposes a picture frame strip splicing positioning buckle device, including an assembly, a connector and a snap-fit ​​component;

[0006] The assembly includes frame strips for forming the picture frame;

[0007] The connector includes a horizontally extending mating plate, which is fixedly installed inside the frame strip, and two symmetrically arranged toothed plates are fixedly installed on both sides of the mating plate;

[0008] The snap-fit ​​component includes an integrally formed clamping frame and a clamping arm. The clamping arm extends downward from the top of the clamping frame to form an elastic cantilever structure. The inner wall of the clamping arm protrudes outward to form multiple upward-inclined protruding teeth, which engage with the toothed plate.

[0009] The snap-fit ​​component also includes a curved groove formed at the connection between the clamping frame and the clamping arm, a connecting groove passing through the connection between the clamping frame and the clamping arm, and a connecting arm, the fixed end of which is fixedly installed in the connecting groove; the curved groove is arc-shaped and recessed along the inner wall of the connection.

[0010] The snap-fit ​​component also includes a pressing mechanism located at the free end of the connecting arm. The pressing mechanism includes an outwardly protruding pressing protrusion and an arc-shaped pressing groove formed below the pressing protrusion.

[0011] Preferably, the assembly further includes a reinforcing plate, and the frame strip has a groove extending along its length, the reinforcing plate being embedded in the groove and forming an integral structure with the frame strip.

[0012] Preferably, the reinforcing plate has a V-shaped cross-section structure, with its tip extending toward the outer wall of the frame strip and its bottom open end connected to the inner wall of the frame strip.

[0013] Preferably, multiple through holes are spaced apart on both sides of the reinforcing plate along its length.

[0014] Preferably, the top of the docking plate has an installation groove, the clamping frame is slidably connected to the inner wall of the installation groove, the bottom of the inner wall of the installation groove has a through hole, the outer wall of the docking plate has an installation hole, the through hole extends into the installation hole, and the bottom of the inner wall of the installation hole has a sliding hole.

[0015] Preferably, a sliding rod is slidably connected to the inner wall of the through hole, the bottom of the sliding rod extends into the sliding hole and is slidably connected thereto, a spring is sleeved on the outer wall of the sliding rod, a limit sleeve is fixedly connected to the outer wall of the sliding rod, and both the limit sleeve and the spring are located in the mounting hole.

[0016] Preferably, one end of the spring is fixedly connected to the limiting sleeve, and the other end of the spring is fixedly connected to the docking plate.

[0017] The beneficial effects of this utility model, achieved through the above technical solution, are as follows:

[0018] 1. Insert the clamping frame onto the two mating plates. The clamping arms compress the toothed plates. The clamping arms engage with the toothed plates through the protruding teeth. Under the elastic clamping force of the clamping arms, the two mating plates can be clamped. This design facilitates the assembly of the frame strips and eliminates the need to drill holes in the frame strips, reducing the manufacturing difficulty.

[0019] 2. By pressing the protrusion, the connecting arm drives the clamping arm to bend at the curved groove, thereby causing the protruding teeth on the clamping arm to disengage from the toothed plate, quickly disassembling the clamping frame, facilitating the separation of the frame strips, making it easier to transport and store, and reducing transportation costs.

[0020] 3. During installation, the clamping frame presses against the slide rod, causing the slide rod to slide into the sliding hole. The slide rod presses upward against the clamping frame, and the outer end of the protruding teeth on the clamping arm tilts upward. Under the elastic force of the spring, the clamping arm can tightly abut against the toothed plate, further improving the stability of the clamping arm installation. Attached Figure Description

[0028] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] In this utility model, unless otherwise explicitly specified and limited, the term "fixed connection" should be interpreted broadly. For example, "fixed connection" can mean fixed installation, detachable connection, or integral; it can mean mechanical connection or electrical connection; it can mean direct connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, a picture frame strip splicing and positioning buckle device includes an assembly 1, a connector 2 and a snap-fit ​​3;

[0031] Assembly 1 includes a frame strip 101 for forming a picture frame;

[0032] The connector 2 includes a horizontally extending mating plate 201, which is fixedly installed inside the frame strip 101. Two symmetrically arranged toothed plates 209 are fixedly installed on both sides of the mating plate 201.

[0033] The snap-fit ​​component 3 includes an integrally formed clamping frame 301 and a clamping arm 304. The clamping arm 304 extends downward from the top of the clamping frame 301 to form an elastic cantilever structure. The inner wall of the clamping arm 304 protrudes outward to form multiple upward-inclined protrusions. The protrusions engage with the toothed plate 209.

[0034] The snap-fit ​​component 3 also includes a curved groove 302 formed at the connection between the clamping frame 301 and the clamping arm 304, a connecting groove 303 passing through the connection between the clamping frame 301 and the clamping arm 304, and a connecting arm 305, the fixed end of the connecting arm 305 being fixedly installed in the connecting groove 303; the curved groove 302 is arc-shaped recessed along the inner wall of the connection.

[0035] The snap-fit ​​component 3 also includes a pressing mechanism located at the free end of the connecting arm 305. The pressing mechanism includes an outwardly protruding pressing protrusion 306 and an arc-shaped pressing groove 307 formed below the pressing protrusion 306.

[0036] Pressing the protrusion 306 causes the clamping arm 304 to bend at the bending groove 302, disengaging the protrusions on the clamping arm 304 from the toothed plate 209, quickly disassembling the clamping frame 301, facilitating the disassembly of the frame strip 101, simplifying transportation and storage, and reducing transportation costs. The connector 2 includes a horizontally extending mating plate 201, which is fixedly installed inside the frame strip 101. Two symmetrically arranged toothed plates 209 are fixedly installed on both sides of the mating plate 201.

[0037] The snap-fit ​​component 3 includes an integrally formed clamping frame 301 and a clamping arm 304. The clamping arm 304 extends downward from the top of the clamping frame 301 to form an elastic cantilever structure. The inner wall of the clamping arm 304 protrudes outward to form multiple upward-inclined protrusions. The protrusions engage with the toothed plate 209.

[0038] The snap-fit ​​component 3 also includes a curved groove 302 formed at the connection between the clamping frame 301 and the clamping arm 304, a connecting groove 303 passing through the connection between the clamping frame 301 and the clamping arm 304, and a connecting arm 305, the fixed end of the connecting arm 305 being fixedly installed in the connecting groove 303; the curved groove 302 is arc-shaped recessed along the inner wall of the connection.

[0039] The snap-fit ​​component 3 also includes a pressing mechanism located at the free end of the connecting arm 305. The pressing mechanism includes an outwardly protruding pressing protrusion 306 and an arc-shaped pressing groove 307 formed below the pressing protrusion 306.

[0040] Pressing the protrusion 306 causes the clamping arm 304 to bend at the bending groove 302, causing the protruding teeth on the clamping arm 304 to disengage from the toothed plate 209, quickly disassembling the clamping frame 301, facilitating the disassembly of the frame strip 101, making it easier to transport and store, and reducing transportation costs.

[0041] The clamping frame 301 is inserted into the two mating plates 201. The clamping arm 304 presses against the toothed plate 209. The clamping arm 304 engages with the toothed plate 209 through the protruding teeth. Under the elastic clamping of the clamping arm 304, the two mating plates 201 can be clamped. This design facilitates the assembly of the frame strip 101 and eliminates the need to drill holes in the frame strip 101, reducing the manufacturing difficulty.

[0042] In some embodiments, such as Figure 2 As shown, the assembly 1 also includes a reinforcing plate 102, and the frame strip 101 is provided with a groove extending along its length direction. The reinforcing plate 102 is embedded in the groove and forms an integral structure with the frame strip 101.

[0043] The one-piece molding structure makes the connection between the reinforcing plate 102 and the frame strip 101 more secure, and can withstand greater external forces without easily deforming or breaking, thus enhancing the structural strength of the frame strip 101.

[0044] In some embodiments, such as Figure 2 As shown, the reinforcing plate 102 has a V-shaped cross-section structure, with its tip extending toward the outer wall of the frame strip 101 and its bottom open end connected to the inner wall of the frame strip 101.

[0045] This design increases the contact area between the reinforcing plate 102 and the frame strip 101, enabling the reinforcing plate 102 to better disperse stress when subjected to external forces, thereby improving the bending resistance of the frame strip 101.

[0046] In some embodiments, such as Figure 2 As shown, multiple through holes 103 are spaced apart along the length of both sides of the reinforcing plate 102.

[0047] Without affecting the structural strength of the reinforcing plate 102, the weight of the reinforcing plate 102 is reduced by opening through holes 103 in the reinforcing plate 102. At the same time, the through holes 103 can also serve as holes for material saving, reducing unnecessary material use and lowering production costs.

[0048] In some embodiments, such as Figures 3-5As shown, the top of the docking plate 201 has an installation groove 203, the clamping frame 301 is slidably connected to the inner wall of the installation groove 203, the bottom of the inner wall of the installation groove 203 has a through hole 204, the outer wall of the docking plate 201 has an installation hole 202, the through hole 204 extends into the installation hole 202, the bottom of the inner wall of the installation hole 202 has a sliding hole 205, the inner wall of the through hole 204 is slidably connected to a sliding rod 206, the bottom of the sliding rod 206 extends into the sliding hole 205 and is slidably connected thereto, the outer wall of the sliding rod 206 is fitted with a spring 208, the outer wall of the sliding rod 206 is fixedly connected to a limiting sleeve 207, the limiting sleeve 207 and the spring 208 are both located in the installation hole 202, one end of the spring 208 is fixedly connected to the limiting sleeve 207, and the other end of the spring 208 is fixedly connected to the docking plate 201;

[0049] Under the elastic force of the spring 208, the clamping arm 304 can be tightly pressed against the toothed plate 209, further improving the stability of the clamping arm 304 installation.

[0050] Working principle: The ends of the frame strip 101 are connected to form a right angle. At this time, the mating plates 201 inside the frame strip 101 are in contact with each other. The clamping frame 301 is inserted into the two mating plates 201. The clamping arm 304 squeezes the toothed plate 209. The clamping arm 304 is engaged with the toothed plate 209 through the protruding teeth. Under the elastic clamping of the clamping arm 304, the two mating plates 201 can be clamped, thereby completing the assembly of the frame strip 101.

[0051] By pressing the protrusion 306, the connecting arm 305 drives the clamping arm 304 to bend at the bending groove 302, thereby causing the protrusion on the clamping arm 304 to disengage from the toothed plate 209, and quickly disassemble the clamping frame 301.

[0052] During installation, the clamping frame 301 presses against the slide rod 206, causing the slide rod 206 to slide into the slide hole 205. The slide rod 206 presses upward against the clamping frame 301, and the outer end of the protruding tooth on the clamping arm 304 tilts upward. Under the elastic force of the spring 208, the clamping arm 304 can tightly abut against the toothed plate 209, further improving the firmness of the clamping arm 304 installation.

[0053] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
