[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0022] As attached Figure 1 , Attachment Figure 3 and attached Figure 4 As shown, a leather shoe bending test device comprises a bottom plate 1, a mounting frame 2 is installed on the upper side of the bottom plate 1, an electric telescopic rod 3 is installed through the upper side of the mounting frame 2, a shoe pressing box body 4 is installed on the extended end of the electric telescopic rod 3, a box cover 5 is installed on one side of the shoe pressing box body 4, a first bending block 6 is rotatably installed on one side of the shoe pressing box body 4, a small motor 10 is installed on the top of the shoe pressing box body 4, the shaft end of the small motor 10 passes through the inside of the shoe pressing box body 4 and is installed with a bevel gear 11, a rotating shaft 14 is rotatably installed on one side wall of the shoe pressing box body 4, a bevel gear 2 12 matched with the bevel gear 11 is installed on the rotating shaft 14, and a connecting block 15 is connected between the first bending block 6 and the rotating shaft 14;
[0023] A second bending block 7 is slidably mounted on one side of the first bending block 6 away from the shoe pressing box body 4 , and a plurality of strip-shaped air bags 9 are respectively mounted on the upper sides of the first bending block 6 and the second bending block 7 .
[0024] Through the above structure, the leather shoes are put on the first bending block 6, the second bending block 7 and the outside of the shoe pressing box body, and the electric telescopic rod 3 is extended to move the leather shoes and the shoe pressing box body 4 downward, and the leather shoes are pressed and positioned on the upper side of the bottom plate 1 by the shoe pressing box body 4, and the position of the second bending block 7 is adjusted according to the size of the leather shoes. The multiple groups of strip airbags 9 are inflated to support the inside of the leather shoes, and the state of the foot entering the leather shoes is simulated. After the small motor 10 is started, it drives the bevel gear 11 to reciprocate, and the bevel gear 11 drives the bevel gear 2 12 and the rotating shaft 14 to rotate, and the connecting block 15 outside the rotating shaft 14 drives the first bending block 6 and the second bending block 7 to swing, thereby driving the leather shoes to bend back and forth, and performing a bending test. The specific structure is as follows:
[0025] Combined with Figure 3 and attached Figure 4 As shown, the sizes of the multiple groups of strip air bags 9 are different, an air pump 17 is installed inside the shoe pressing box body 4, and multiple groups of air supply pipes 18 connected to the strip air bags 9 are installed at the connecting end of the air pump 17. The part of the air supply pipe 18 located on the inner side of the shoe pressing box body 4 is a hard pipe, and the part of the air supply pipe 18 located on the outer side of the shoe pressing box body 4 is a soft pipe.
[0026] Through the above structure, after the multiple groups of strip air bags 9 are filled with air, they are similar to the shape of the upper side of the sole, thereby simulating the state of the foot wearing into the inside of the leather shoe. The gas is transported to the air supply pipe 18 through the air pump 17, and the air is sent to the multiple groups of strip air bags 9 through the air supply pipe 18. The air supply pipe 18 located on the inner side of the shoe pressing box body 4 is a hard pipe to prevent the air supply pipe 18 from contacting with the bevel gear 11 and causing damage. The air supply pipe 18 located on the outer side of the shoe pressing box body 4 is a hose, and the hose is long, so that when the first bending block 6 and the second bending block 7 are bent, the air supply pipe 18 can bend accordingly.
[0027] Combined with Figure 2 As shown, a control switch 13 connected to the electric telescopic rod 3, a small motor 10 and a driving air pump 17 is installed on one side of the mounting frame 2.
[0028] Through the above structure, the electric telescopic rod 3, the small motor 10 and the driving air pump 17 are controlled by the control switch 13.
[0029] Combined with Figure 3 As shown, a sliding telescopic block 8 is installed on one side of the second bending block 7 close to the first bending block 6. The sliding telescopic block 8 slides into the first bending block 6. The shoe pressing box body 4 is provided with a cutout 16 for the connecting block 15 to swing through.
[0030] Through the above structure, the second bending block 7 is adjusted in position by sliding and retracting the sliding retractable block 8 inside the first bending block 6. The sliding retractable block 8 is limited inside the first bending block 6 and will not be pulled out from the first bending block 6. The incision 16 will not limit the upward swinging angle of the connecting block 15, so that the leather shoes can be bent at various angles. Air is supplied to the inside of the shoe pressing box body 4 through the incision 16 for use by the air pump 17, and the incision 16 is also used to facilitate heat dissipation of the internal equipment of the shoe pressing box body 4.
