Furthermore, the chuck main body is a U-shaped groove, and a downward arc-shaped notch is arranged on the front panel.

Further, the stroke of the electric cylinder is 1000mm.

Furthermore, still be equipped with guide arm and baffle on the electric jar mount, the guide arm be equipped with more than two, the parallel mount top and below of locating, the baffle be connected with the front end of guide arm is perpendicular, electric jar carriage release lever pass the baffle and be connected with the force value sensor.

The utility model has the advantages that:

the utility model provides a furniture drawer durability testing arrangement adopts servo motor and accurate lead screw to adjust the upper and lower displacement of electric jar, and the push-and-pull stroke of drawer is controlled to the stroke through the electric jar, has universal caster's bottom plate ability rotation angle wantonly simultaneously, can adapt to the furniture of various models and sizes. In addition, the specially designed drawer joint can quickly lap various types of drawer handles.

In a word, the utility model provides a novel drawer test device, more comprehensive adaptation market demand, and further improved degree of automation, it is easy and simple to handle, only need one-man operation can test fast, it is efficient.

The technical solution of the present invention is illustrated below with reference to the accompanying drawings and examples.

Drawings

Fig. 1 is a schematic front side view of a durability testing device for a drawer of a furniture according to an embodiment of the present invention.

Fig. 2 is a schematic rear side view of a durability testing device for a furniture drawer according to an embodiment of the present invention.

The specific implementation mode is as follows:

the specific embodiments described herein are merely illustrative of the principles of this patent and are not intended to limit the scope of the disclosure. It should be noted that, for convenience of description, only a part of the structure related to the technical solution of the present application is shown in the drawings, not the whole structure.

Before discussing exemplary embodiments in greater detail, it should be noted that the structures of the device components and/or the modules themselves mentioned in the embodiments, if not specified in detail, are those that can be understood or commercially available to those skilled in the art in light of the present disclosure.

Referring to fig. 1 and 2, the furniture drawer durability testing device that this embodiment provided includes universal caster 1, bottom plate 2, PLC control cabinet 3, section bar support 4, servo motor 5, lead screw 6, steering nut 7, electric cylinder mount 8, electric cylinder 9, force value sensor 10 and

chuck

11, 2 four corners of bottom plate all be equipped with universal caster 1, PLC control cabinet 3 and section bar support 4 locate on bottom plate 2, servo motor 5 locate the top of section bar support 4, lead screw 6 vertically locate in section bar support 4, the top of lead screw 6 and servo motor 5's output shaft, steering nut 7 and lead screw 6 mesh, electric cylinder mount 8 and steering nut 7 fixed connection, electric cylinder 9 transversely locate on electric cylinder mount 8, force value sensor 10 locate between the carriage release lever and the chuck 11 of electric cylinder, servo motor 5, electric cylinder 9 and force value sensor 10 all be connected with PLC control cabinet signal or electricity.

In order to adapt to various drawer handles of different types on the market, the drawer handles are quickly connected.
