Description

Technical Field

[0001] The invention relates to the technical field of glass door frames, in particular to a conductive glass door frame of a display cabinet which can be connected in series. Background Art

[0002] Traditional glass door frames are customized into two-door frames, three-door frames or five-door frames according to the length requirements, and then assembled into the required length. A vertical beam is welded between the upper and lower beams of the two-door frame, two vertical beams are welded between the upper and lower beams of the three-door frame, and four vertical beams are welded between the upper and lower beams of the five-door frame, and the left and right frames remain unchanged. The size of the two-door frame, three-door frame or five-door frame is large, and the packaging volume is also large, but the weight is relatively light. In the existing transportation packaging system, the glass door frame occupies a large volume, and the weight becomes heavier after the outer packaging. During the transportation process between the production enterprise and the display cabinet manufacturer, it is easy to cause the crossbeams and longitudinal beams of the product to bend, which is very inconvenient to transport. In the process of assembling the glass door frame and the cabinet body, the weight of the two-door frame, three-door frame or five-door frame is heavy relative to two people, and the labor intensity is high. Summary of the invention

[0003] The purpose of the present invention is to solve the deficiencies of the above-mentioned technology and to provide a conductive glass door frame of a display cabinet that can be connected in series, so as to realize mechanical connection and circuit connection between independent door frame units.

[0004] In order to achieve the above-mentioned purpose, the present invention is a display cabinet conductive glass door frame that can be connected in series, including door frame units, each of which is provided with a power supply wire and a connecting wire for connecting the power supply wire and the electrical component, and adjacent door frame units are provided with mutually cooperating connecting mechanisms to achieve mechanical and electrical connection between adjacent door frame units.

[0005] The door frame unit includes an upper crossbeam, a lower crossbeam and a vertical beam. Both ends of the upper crossbeam and the lower crossbeam are connected by a vertical beam to form a rectangular frame. Both ends of the upper crossbeam and the vertical beam are connected by an angle code, and both ends of the lower crossbeam and the vertical beam are connected by an angle code. A power supply wire is arranged inside the upper crossbeam and / or the lower crossbeam, and a connecting wire is arranged inside the upper crossbeam, the lower crossbeam and the vertical beam, and the connecting wire is connected to the power supply wire; the angle code includes a body, a No. 1 connecting piece, a No. 2 connecting piece and a door shaft connecting piece. The No. 1 connecting piece is used to connect the upper crossbeam or the lower crossbeam, and the No. 2 connecting piece is used to connect the upper crossbeam or the lower crossbeam. For connecting vertical beams, the door axis connector is used to connect door axis, at least three wiring sockets are arranged on the main body, and the wiring sockets are connected to each other through conductive metal sheets. The metal sheets are arranged inside the main body or connected to the main body as an integrated structure through injection molding. The power supply wire is connected to one of the wiring sockets on the main body, and the other wiring socket is used to connect electrical components. The remaining wiring socket is used for electrical connection between the angle codes of adjacent door frame units through external wires; a connecting mechanism is arranged on the main body of the angle code, and the connecting mechanisms on the two angle codes are connected to each other in a coordinated manner.

[0006] The above technical solution uses a door frame as a minimum door frame unit. During the assembly of the display cabinet, multiple door frame units can be spliced ​​according to actual needs, and mechanical assembly and electrical connection can be achieved after splicing. A metal sheet is arranged inside the corner code and at least three wiring sockets are arranged on the main body, so that the left and right ends of the door frame unit can be electrically connected through the power supply wire, and the corner codes of adjacent door frame units are connected to the circuit through external wires, and corresponding wiring sockets are arranged on the corner code, so the connection of the external wires is simple and convenient, and there will be no connection errors. At the same time, the wiring ports are arranged on the corner code for connecting electrical components. The above scheme realizes the mechanical assembly and electrical connection between the door frame units, so that the door frame production has the form of standard parts, and it can be connected according to actual needs during use, which is more convenient to transport and not easy to be damaged during transportation.

[0007] An axial hole with a semicircular cross section is provided on one of the side walls of the body of the angle code, and the axial hole and the No. 1 connecting piece are respectively provided on the two opposite side walls of the body, and semicircular ring-shaped grooves are provided on the side walls of the body at both ends of the axial hole; after the two adjacent door frame units are docked, the axial holes on the adjacent angle codes form a circular through hole, and the semicircular ring-shaped grooves on the adjacent angle codes form a circular ring groove, and a circular ring connecting ring is provided in the circular ring groove, and a combination of bolts and nuts is provided in the circular through hole to confine the circular ring connecting ring in the circular ring groove. The design of this structure can better realize the connection between adjacent door frames through the angle code, and only needs to use the circular ring connecting ring to be set inside the circular ring groove, and fixed and limited by a combination of bolts and nuts, so that the two adjacent door frames can be fixedly connected, and the connection is firm and stable. Moreover, the connection structure will not occupy too much space, nor will it protrude from the angle code body, so the aesthetics and the subsequent sealing of the door frame and door leaf will not be affected.

[0008] The extension directions of the No. 1 connector, the No. 2 connector and the door shaft connector on the body are perpendicular to each other. The No. 1 connector is provided with a through hole for connecting with the upper crossbeam or the lower crossbeam, and the No. 2 connector is provided with a through hole for connecting with the vertical beam. The design of this structure can better ensure the verticality of the connection between the upper crossbeam, the lower crossbeam and the vertical beam, and at the same time ensure the matching degree between the door shaft and the door frame after assembly, and the matching performance is better.

[0009] Two power supply wires are arranged inside the door frame unit, and six wiring sockets are arranged on the angle bracket body, of which three wiring sockets are connected through one metal sheet, and the other three wiring sockets are connected through one metal sheet. The design of this structure enables two passages to be arranged inside the angle bracket, one of which is used to connect the upper beam, lower beam, and electrical components inside the door frame unit, and the other can be connected to the electrical components inside the door leaf through the door shaft, so that the voltage and current of the two circuits can be controlled separately to improve the performance.

[0010] The conductive glass door frame of the display cabinet that can be connected in series can realize the mutual connection between independent door frames, and the adjacent door frames can be mechanically assembled and electrically connected through angle brackets, and multi-path independent conduction can be realized through the metal sheets and wiring sockets inside the angle brackets.

[0011] The present invention converts the splicing of two door frames, three door frames or five door frames into the splicing of several single door frames of equal length according to the cabinet openings with different length requirements. For example, two door frames are spliced ​​with two single door frames of equal width, three door frames are spliced ​​with three single door frames of equal width, four door frames are spliced ​​with four single door frames of equal width, etc. During the splicing process, the mechanical strength and electrical connection remain unchanged, the production is easy and convenient for automated production, the transportation process becomes easier, and the labor intensity is also reduced.
