DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] The multimedia intelligent display cabinet is a wall-type display cabinet. The front and two sides of the display cabinet body 6 are transparent. The display cabinet body 6 is equipped with multimedia devices such as lighting devices, voice devices, and playback devices. The lines of all the multimedia devices that use electricity are concentrated together and led out from the back of the display cabinet body 6;

[0030] like Figure 1-5 As shown, a track plate 1 and an auxiliary track 7 are fixed horizontally on the wall, the track plate 1 and the auxiliary track 7 are arranged parallel to each other, a track groove 11 is arranged at the bottom of the auxiliary track 7 and the top of the track plate 1, a plurality of positioning grooves 2 are arranged at equal intervals on the surface of the track plate 1, two electrode strips 5 penetrate the track plate 1, one end of the two electrode strips 5 is connected to the mains, and the electrode strips 5 are exposed on the upper and lower sides of each of the positioning grooves 2;

[0031] like Figure 5-6As shown, a bracket 8 is fixedly installed on the back of the display cabinet 6, two upper guide wheels 81 are rotatably installed on the upper part of the bracket 8, and two lower guide wheels 82 are rotatably installed on the lower part of the bracket 8. The upper guide wheels 81 and the lower guide wheels 82 are respectively inserted into the track groove 11, so that the display cabinet 6 can move horizontally along the track plate 1 and the auxiliary track 7. The positioning block 4 slides through the surface of the bracket 8, and the positioning block 4 and the bracket 8 are connected by a spring, so that the positioning block 4 is moved closer to the display cabinet 6 under the action of elastic force, and the positioning block 4 is slidably adapted to the positioning groove 2. Two electrode blocks 44 are installed at the upper and lower positions of the positioning block 4, and the multimedia device circuits of the display cabinet 6 are connected to the two electrode blocks 44;

[0032] like Figure 6-7 As shown, the locking assembly includes a screw rod 9, which is vertically threaded and mounted on the surface of the bracket 8. A bevel block 91 is rotatably arranged on the top of the screw rod 9. The bevel block 91 is flatly attached to the surface of the bracket 8 to restrict it from rotating. The portion of the positioning block 4 close to the bevel block 91 has a bevel, and the bevel block 91 is in parallel contact with the bevel of the positioning block 4.

[0033] The position of the display cabinet 6 can be adjusted linearly by rolling the upper guide wheel 81 and the lower guide wheel 82 in the track groove 11, and then the lower end of the screw rod 9 is rotated to make the screw rod 9 push the inclined surface block 91 upward, and the inclined surface block 91 contacts the inclined surface of the positioning block 4 so that the positioning block 4 overcomes the elastic force and moves toward the direction of the track plate 1, and the positioning block 4 slides and inserts into the aligned positioning groove 2 to lock the position of the display cabinet 6, and at the same time, the movable block 43 is aligned and contacted with the electrode strip 5, so that the multimedia device circuit of the display cabinet 6 is connected;

[0034] When adjusting the position of the display cabinet 6, the positioning block 4 and the positioning groove 2 are in a separated state, the movable block 43 does not contact the electrode strip 5, and the circuit of the multimedia device is in an open circuit state, making the position adjustment safer.

[0035] like Figure 6 As shown, a plurality of convex strips are arranged in parallel in the track groove 11 at the top of the track plate 1, and a plurality of annular grooves are arranged on the surface of the upper guide wheel 81. The convex strips are aligned and snapped into the annular grooves to limit the front and rear positions of the upper guide wheel 81, so that the front and rear positions of the display cabinet 6 are fixed to prevent the display cabinet 6 from shaking in the front and rear directions.

[0036] like Figure 2-3 As shown, the retaining shell 3 is installed in the positioning groove 2 by elastic sliding of a spring. When the positioning block 4 is not inserted into the positioning groove 2, the retaining shell 3 is sealed at the port of the positioning groove 2 by the elastic force, and the side of the retaining shell 3 covers the exposed part of the electrode strip 5, effectively preventing dust and moisture from entering the vacant positioning groove 2 to contaminate the surface of the electrode strip 5 and affect the conductive effect.

[0037] The specific installation of the electrode block 44 is as follows:

[0038] like Figure 2-3 As shown, an active cavity 41 is provided in the positioning block 4, two active blocks 43 slide symmetrically in the active cavity 41, a spring is connected between the two active blocks 43, so that the two active blocks 43 shrink and fit together, an electrode block 44 is fixed on the outer side of the active block 43, and openings 42 for aligning the electrode block 44 are provided on the upper and lower sides of the positioning block 4, a touch handle 45 with hemispherical ends is slidably penetrated through the end face of the positioning block 4, the ends of the active blocks 43 have inclined surfaces, the inclined surfaces of the two active blocks 43 are in a V shape, and the touch handle 45 abuts against the inclined surfaces of the active blocks 43;

[0039] When the positioning block 4 is in the non-plugged state, the two movable blocks 43 are contracted by the elastic force, and the electrode block 44 does not protrude from the through-opening 42. When the positioning block 4 is inserted into the positioning groove 2, the contact handle 45 resists the stop shell 3 and contracts into the positioning groove 2. The resistance reaction force of the contact handle 45 causes the contact handle 45 to resist the inclined surfaces of the two movable blocks 43, so that the two movable blocks 43 have a tendency to overcome the elastic force and expand and move. When the stop shell 3 shrinks to the point where it cannot move, the positioning block 4 is continuously inserted, so that the contact handle 45 resists the expansion of the movable block 43, and the two electrode blocks 44 pass through the through-opening 42 to squeeze the contact electrode strip 5, thereby improving the circuit connection stability.

[0040] A ball groove 31 is provided on the surface of the stop shell 3, and the end of the touch handle 45 is adapted to abut against the ball groove 31. When adjusting the position of the display cabinet 6, the touch handle 45 will produce a feeling of elastic docking when passing through the stop shell 3 and aligning the ball groove 31, which is convenient for the operator to align the positioning block 4 with the positioning groove 2.

[0041] like Figure 6-7 As shown, a slide groove is provided at the lower part of the bracket 8, and a carrier 83 is slidably arranged at the lower part of the bracket 8 along the slide groove. Two lower guide wheels 82 are rotatably mounted on the surface of the carrier 83. A spring is sleeved on the outer side of the screw rod 9, one end of the spring abuts against the handle at the end of the screw rod 9, and the other end of the spring elastically abuts against the carrier 83 upwards;

[0042] The adjustment of the locking assembly has three states, namely, disassembly state, moving state, and positioning state;

[0043] Disassembly state: completely loosen the screw rod 9 downwards so that the spring cannot elastically resist the carrier 83, and the lower guide wheel 82 follows the carrier 83 to descend, and the lower guide wheel 82 is disengaged from the track groove 11 of the auxiliary track 7, so as to remove the display cabinet 6 from the track plate 1 and the auxiliary track 7;

[0044] Moving state: the moving screw rod 9 is rotated upward to make the spring squeeze the carrier 83 move upward, and the lower guide wheel 82 remains stuck in the track groove 11 of the auxiliary track 7. At this time, the inclined block 91 does not squeeze the positioning block 4, and only makes the upper guide wheel 81 and the lower guide wheel 82 roll and support the display cabinet 6, so that the display cabinet 6 can be moved and adjusted;

[0045] Positioning state: the screw rod 9 is continuously rotated upwards to make the inclined block 91 contact the positioning block 4 and snap into the positioning groove 2. At this time, the position of the display cabinet 6 is positioned and fixed, and the elastic force of the spring on the carrier 83 is increased, so that the lower guide wheel 82 and the upper guide wheel 81 support the display cabinet 6 more stably.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
