Description

Technical Field

[0001] This utility model relates to the field of display cabinets, and in particular to a display cabinet frame connection structure. Background Technology

[0002] A display case is a piece of furniture or fixture specifically designed for displaying items, widely used in retail, museums, exhibitions, and homes. Currently, acrylic and glass display cases are the most common. The construction process for both types generally involves first building a frame structure, then attaching the glass / acrylic to the frame using strong adhesive to achieve a vertically transparent display effect on all four sides. However, this method is problematic when the display case is large, as the large pieces of glass / acrylic are very heavy, especially the glass. The adhesive cannot ensure a stable and secure connection between the large glass pieces and the frame. Furthermore, these display cases are disposable and cannot be repeatedly disassembled and reassembled. Utility Model Content

[0003] To overcome the above problems, this utility model provides a display cabinet frame connection structure. The technical solution adopted by this utility model to solve its technical problems is as follows:

[0004] A display cabinet frame connection structure includes vertical frame strips and horizontal frame strips. The sidewalls of the vertical frame strips are vertically provided with T-shaped grooves, and the ends of the horizontal frame strips are provided with connecting components. The horizontal frame strips are connected to the T-shaped grooves of the vertical frame strips via the connecting components, forming a frame structure after locking. The connecting component includes a connecting sleeve with a connecting hole inside. One end of a connecting post slides through the connecting hole, and the other end of the connecting post has a T-shaped head. The sidewall of the connecting post has an inclined surface, which, when pressed, drives the connecting post to slide into the connecting hole. The sidewall of the connecting sleeve has a locking hole perpendicular to the connecting hole, and the locking hole communicates with the connecting hole. The T-shaped head is fitted into the T-shaped groove, and a locking screw is screwed into the locking hole and presses against the inclined surface, thus locking and fixing the sidewalls of the vertical frame strips to the ends of the horizontal frame strips.

[0005] Furthermore, an elastic element is provided inside the connecting hole, and one end of the connecting post is pressed against the elastic element. The elastic element has a tendency to drive the connecting post to slide out of the connecting hole.

[0006] Furthermore, a screw sleeve is provided inside the locking hole, and the locking screw is screwed into the locking hole through the screw sleeve.

[0007] Furthermore, the screw sleeve is detachably installed in the locking hole, and the side wall of the screw sleeve is provided with a through hole that passes through the screw sleeve. The diameter of the through hole is equal to the diameter of the connecting hole, and the connecting post passes through the connecting hole and through the through hole.

[0008] Furthermore, the locking screw is a headless hexagonal screw, and the front end of the locking screw is hemispherical to press against the bevel.

[0009] Furthermore, a limiting sleeve is provided at the end of the horizontal frame strip, and an alignment hole is provided on the side wall of the limiting sleeve. The connecting sleeve is placed inside the limiting sleeve, and the locking hole coincides with the alignment hole. The locking screw passes through the alignment hole into the locking hole.

[0010] Furthermore, before tightening the locking screw, the T-head can slide up and down within the T-slot to adjust the vertical position of the horizontal frame relative to the vertical frame.

[0011] Furthermore, the connecting sleeve is provided with abutment blocks, which are distributed near the opening of the connecting hole. When the vertical frame strip and the horizontal frame strip are locked and fixed, the abutment blocks abut against the vertical frame strip.

[0012] The beneficial effects of this utility model are:

[0013] The structure includes vertical and horizontal frame bars. The sidewalls of the vertical frame bars have vertically formed T-slots, and the ends of the horizontal frame bars have connecting components. The horizontal frame bars connect to the T-slots of the vertical frame bars via the connecting components, forming a frame structure after locking. The connecting components include connecting sleeves with connecting holes. One end of a connecting post slides through the connecting hole, and the other end of the connecting post has a T-shaped head. The sidewall of the connecting post has an inclined surface, which, when pressed, drives the connecting post to slide into the connecting hole. The sidewall of the connecting sleeve has a locking hole perpendicular to the connecting hole, and the locking hole connects to the connecting hole. In use, assuming there is glass between the two vertical frame bars, the T-shaped head of the horizontal frame bar is fitted into the T-slot, and the locking screw is screwed into the locking hole and presses against the inclined surface, locking the sidewalls of the vertical frame bars to the ends of the horizontal frame bars, firmly clamping and fixing the glass to the frame bars. This structure can be repeatedly disassembled and can be used for display cabinets of different sizes. Attached Figure Description

[0022] To better understand the purpose, structure, and function of this utility model, the following detailed description of a specific embodiment of the utility model "a display cabinet frame connection structure" is provided in conjunction with the accompanying drawings.

[0023] See Figures 1-4 In this embodiment, the display cabinet frame connection structure includes a vertical frame strip 100 and a horizontal frame strip 200. The side wall of the vertical frame strip 100 is vertically provided with a T-shaped groove 101. The end of the horizontal frame strip 200 is provided with a connecting component. The horizontal frame strip 200 is connected to the T-shaped groove 101 of the vertical frame strip 100 through the connecting component, and a frame structure is formed after locking. The connecting component includes a connecting sleeve 201. The connecting sleeve 201 is provided with a connecting hole 202. One end of the connecting post 203 is slidably inserted into the connecting hole 202. The other end of the connecting post 203 is provided with a T-shaped head 204. The side wall of the connecting post 203 is provided with an inclined surface 205. When the inclined surface 205 is pressed, it drives the connecting post 203 to slide into the connecting hole 202. The side wall of the connecting sleeve 201 is provided with a locking hole 206 perpendicular to the connecting hole 202. The locking hole 206 communicates with the connecting hole 202. When assembling a glass display case using connecting components, the glass is first clamped between two vertical frame bars 100. The two ends of the glass can be embedded in the T-slots 101 for limitation, or additional limiting slots can be provided on the side walls of the vertical frame bars 100 to limit the two ends of the glass. Then, the T-heads 204 are fitted into the T-slots 101, and the locking screws 207 are screwed into the locking holes 206. The locking screws 207 press against the inclined surfaces 205. After being pressed, the inclined surfaces 205 drive the connecting posts 203 to slide into the connecting holes 202, thereby driving the T-heads 204 to pull the outer wall of the T-slots 101 toward the end of the horizontal frame bars 200, so that the side walls of the vertical frame bars 100 and the end of the horizontal frame bars 200 are locked and fixed, firmly clamping the glass between the vertical frame bars 100 and forming a stable frame structure. This structure first clamps the glass between the vertical frame bars 100, and then locks it in place with the horizontal frame bars 200 to form a frame structure, so that the glass is firmly clamped in the frame. Even large display cases can use this connection mechanism. In addition, this structure is detachable, which is convenient for disassembly, transportation and reuse.

[0024] See further Figure 3 and Figure 4In this embodiment, an elastic element 208 is provided inside the connecting hole 202, preferably a spring; one end of the connecting post 203 is pressed against the elastic element 208, and the elastic element 208 has a tendency to drive the connecting post 203 to slide out of the connecting hole 202. When disassembling the display cabinet, it is only necessary to loosen the locking screw 207, and the elastic element 208 will drive the connecting post 203 to slide out of the connecting hole 202, actively separating the side wall of the vertical frame strip 100 from the end of the horizontal frame strip 200, making it convenient to remove the horizontal frame strip 200 from the vertical frame strip 100.

[0025] More specifically, in this embodiment, a screw sleeve 209 is provided inside the locking hole 206, and the locking screw 207 is screwed into the locking hole 206 through the screw sleeve 209, so that the locking screw 207 can be stably screwed into / out of the locking hole 206 without damaging the locking hole 206, thereby reducing wear on the locking hole 206 during repeated disassembly and assembly. Furthermore, in this embodiment, the screw sleeve 209 is detachably disposed within the locking hole 206. The side wall of the screw sleeve 209 is provided with a through hole 210 penetrating through the screw sleeve 209, the diameter of which is equal to the diameter of the connecting hole 202. In use, the screw sleeve 209 is first placed within the locking hole 206, and the screw sleeve 209 is adjusted so that the through hole 210 on the side wall of the screw sleeve 209 is aligned with the connecting hole 202. Then, the connecting post 203 is inserted into the connecting hole 202 and passes through the through hole 210, thus fixing the screw sleeve 209 in the locking hole 206. Afterward, the locking screw 207 is screwed into the screw sleeve, and the locking screw 207 abuts against the inclined surface 205. This detachable screw sleeve 209 design allows for the replacement of worn screw sleeve 209 after multiple disassemblies and reassemblies.

[0026] See further Figure 4 In this embodiment, the locking screw 207 is a headless hexagonal screw, so that the locking screw 207 can be completely screwed into the screw sleeve 209 without the screw head being exposed and affecting the aesthetics of the display case; and the front end of the locking screw 207 is hemispherical, which makes it convenient for the screw to press against the inclined surface 205 regardless of the angle of rotation, applying vertical pressure and driving the connecting column 203 to slide.

[0027] See further Figure 3 In this embodiment, a limiting sleeve 211 is provided at the end of the horizontal frame 200. The side wall of the limiting sleeve 211 is provided with an alignment hole 212. When the connecting sleeve 201 is placed inside the limiting sleeve 211, the locking hole 206 coincides with the alignment hole 212. The locking screw 207 passes through the alignment hole 212 into the locking hole 206. During disassembly and assembly, after removing the locking screw 207, the connecting sleeve 201 can be removed from the limiting sleeve 211 so that the entire connecting assembly can be replaced if a problem occurs.

[0028] See further Figure 2 and Figure 3 In this embodiment, before the locking screw 207 is tightened, the T-head 204 can slide up and down in the T-slot 101, so as to adjust the vertical position of the horizontal frame strip 200 relative to the vertical frame strip 100 and adapt to the clamping and positioning of glass of different heights.

[0029] More specifically, in this embodiment, the connecting sleeve 201 is provided with an abutment block 213, which is preferably made of wear-resistant material such as plastic or rubber. The abutment block 213 is distributed near the opening of the connecting hole 202. When the vertical frame strip 100 and the horizontal frame strip 200 are locked and fixed, the abutment block 213 abuts against the vertical frame strip 100 to increase the friction. At the same time, the abutment block 213 can play a buffering role between the side wall of the vertical frame strip 100 and the end of the horizontal frame strip 200 to prevent wear.
