The mechanical driving device designed according to the utility model, the bidirectional rotation of the show cabinet which is controlled by customers alone can be realized, the requirements of the customers can be met. The device of the utility model also has the advantages of simple structure and convenient operation.

Description

The mechanical driving device of goods showing cabinet

The utility model relates to the mechanical driving device of goods showing cabinet.

Goods showing cabinet is the device that is used for displaying merchandise in the shop.In the daily merchandise sales, goods showing cabinet is the console mode structure of cuboid, and its end face and leading flank are equipped with glass, and client watches the commodity of displaying by end face and leading flank.The mode of selling goods is enclosed, and a shop-assistant will receive the multidigit client simultaneously, and therefore, it has increased shop-assistant's workload on the one hand, on the other hand, also influences client's picking commodities carefully.As above-mentioned improvement, a kind of is to adopt open form to sell, for example, the supermarket, another kind is that commodity are placed on the tower shelf, that a kind of purchase condition of all having improved client to a certain extent is prerequisite but move with goods based on client.As the improvement of tower shelf is to be equipped with on it to make the device that tower shelf rotate and can only rotate with a direction, and fixes, can not be with client's desire backward rotation.On the other hand, this tower showcase does not aim at the lighting device of its configuration.

Therefore, the purpose of this utility model is to provide a kind of mechanical driving device that can overcome goods showing cabinet not enough in the prior art.

Comprise that according to the mechanical driving device of goods showing cabinet of the present utility model places the pedestal of being made up of base plate and top board and column therebetween on the goods showing cabinet base cabinet, a quill shaft, its lower end is fixed in the positioning sleeve that is fixed on the base plate, the upside of top board has a step dead axle cover fixed thereon, described quill shaft extends upward by described top board and positioning sleeve, a following rolling bearing is contained in the affixed gear wheel in outer ring on the described positioning sleeve, the gears engaged on this gear and the motor output shaft that is contained in below the top board; Top affixed lower plate that is used to connect showcase of gear wheel; The top of quill shaft is equipped with one and is gone up rolling bearing, and the outer ring of this bearing is contained in the bearing block that fuses with rebound, and described rebound is connected with the upper plate that is secured to showcase; Described motor is from the reversible synchronous motor of speed change.

Obviously, have simple in structurely according to the mechanical driving device of goods showing cabinet of the present utility model, cost is low, main has satisfied excellent that client is convenient to do shopping

Above-mentioned purpose of the present utility model and advantage thereof will be more readily apparent from by the detailed description below in conjunction with the accompanying drawing illustrated embodiment, and accompanying drawing has:

Fig. 1 is the example of goods showing cabinet;

Fig. 2 is an embodiment according to the mechanical driving device of goods showing cabinet of the present utility model.

At first referring to Fig. 1, goods showing cabinet comprises a base cabinet 1, the mechanical driving device that the showcase 2 of a plurality of showing stands of tool of a tower shape and being used between base cabinet 1 and showcase 2 can be rotated showcase 2 with respect to base cabinet 1, the commodity of displaying place showing stand.A plurality of lighting devices are housed on the showcase 2, generally are the downsides that is contained in showing stand, with the showing stand that throws light on below it, lighting device can be equipped with in the top of showcase 2, for example the illuminated signs case has the special formed lighting device with the generation aesthetic effect, for example the chrysanthemum type lighting device.Obviously, illuminated signs case and/or the special formed lighting device top of uppermost showing stand of also throwing light on.

Referring now to Fig. 2,, an embodiment according to the mechanical driving device of goods showing cabinet of the present utility model is described.Mechanical driving device 3 comprises that places the pedestal of being made up of base plate 11 and top board 12 and column 13 therebetween above the goods showing cabinet base cabinet 1, the lower end of quill shaft 15 is fixed in the positioning sleeve 14 that is fixed on the base plate 11, top board 12 upsides have a step dead axle cover 16 fixed thereon, described quill shaft 15 passes top board 12 and dead axle cover 16 extends upward, the inner ring of following rolling bearing 17 is contained on the dead axle cover 16, pinion 20 engagements on the affixed gear wheel 18 in its outer ring, gear wheel 18 and the output shaft that is installed in the motor 19 below the top board 12.Top affixed lower plate 21 that is used to connect showcase 2 of gear wheel 18, its effect will illustrate below.The top of quill shaft 15 is equipped with one and is gone up rolling bearing 26, and the outer ring of this bearing is contained in the bearing block 25 that fuses with rebound 27, and rebound 27 joins with upper plate 28, upper plate 28 and showcase 2 Joints.Therefore, lower plate 21 and upper plate 28 constitute the supporting to showcase 2 together, so, when motor 19 work, showcase 2 can be rotated with respect to quill shaft 15 by pinion 20 and the gear wheel 18 that meshes.Need to prove that described motor 19 is the reversible synchronous motors from speed change, the characteristics of this reversible synchronous motor are when the external force that stops reversible synchronous motor to rotate during greater than reversible synchronous motor torque, reversible synchronous motor will change the direction of original rotation, towards rotating with the direction of original direction of rotation.Therefore, can under client's automatic control, change the rotation direction of showcase according to the mechanical driving device of goods showing cabinet of the present utility model, so that can be more suitable for client's Yu demand.

The device that also comprises the lighting device power supply on showcase 2 according to mechanical driving device of the present utility model, this device comprises a following conducting ring 22 that is contained on the quill shaft 15, corresponding with it is the last conducting ring 24 that is contained in rebound 27 downsides, electrical connection between them is to contact realization with carbon brush 23 with following conducting ring 22 by the spring 29 that is contained in the conducting ring 24, therefore, the power supply of introducing from quill shaft 15 can finally be incorporated on the showcase 2 through last conducting ring 24, uses for the lighting device on it.

The applicant has made detailed explanation to the utility model by way of example; can make various improvement and conversion on this basis for the professional and technical personnel; but these conversion and improvement all do not break away from spirit of the present utility model, all within the protection domain that claims limited.
