DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 3 The utility model provides a technical solution: comprising a shell 1 and a rotation resistance adjustment component 5, wherein the rotation resistance adjustment component 5 is arranged inside the shell 1, and the rotation resistance adjustment component 5 comprises a friction block 501, an extrusion block 502, a guide rod 503, a threaded sleeve 504, a support plate 505, a threaded rod 506 and a first gear 507, wherein the side of the friction block 501 close to the left and right walls of the shell 1 is connected with the extrusion block 502, and the side of the extrusion block 502 away from the friction block 501 is connected with the guide rod 503 around, the middle part of the side of the extrusion block 502 away from the friction block 501 is connected with an elastic block 508, the side of the elastic block 508 away from the extrusion block 502 is connected with the threaded sleeve 504, and the outside of the threaded sleeve 504 is connected with the support plate 505, the inside of the threaded sleeve 504 is connected with the threaded rod 506, and the end of the threaded rod 506 away from the threaded sleeve 504 is connected with the first gear 507;

[0022] By rotating the threaded rod 506 to control the degree of compression of the elastic block 508 by the threaded sleeve 504, the contact force between the friction block 501 and the rotating block 402 is controlled, and then the load of the motor 3 is controlled, so that the device can change the load without stopping, thereby making it easier for the device to observe the durability of the motor under different loads.

[0023] like Figures 1 to 5As shown, a connection component 4 is connected to one side of the rotation resistance adjustment component 5 close to the central axis of the shell 1, and a motor 3 is connected to one side of the connection component 4, and a sliding component 2 is connected to the lower end of the motor 3, and support frames 6 are arranged on the left and right sides of the rotation resistance adjustment component 5, and a transmission component 7 is arranged at the lower end of the rotation resistance adjustment component 5, and a cooling component 8 is arranged below the middle of the transmission component 7, and a fan 9 is installed at the lower end of the shell 1;

[0024] The fan 9 can facilitate the diffusion of the cold air generated by the condenser 802, thereby making it easier to cool the friction block 501.

[0025] like Figure 3 As shown, the sliding assembly 2 includes a sliding block 201 and a sliding track 202, and the lower end of the sliding block 201 is connected to the sliding track 202;

[0026] The motor 3 is mounted on the sliding block 201 , and the motor 3 is pushed into the device by means of the sliding structure between the sliding block 201 and the sliding track 202 .

[0027] like Figure 3 and Figure 5 As shown, the connection assembly 4 includes a connection head 401 and a rotating block 402, and the side of the connection head 401 away from the motor 3 is connected to the rotating block 402;

[0028] The rotating end of the motor 3 is inserted into the connector 401 for connection, and the connector 401 drives the rotating block 402 to rotate for durability testing.

[0029] like Figure 4 As shown, the transmission assembly 7 includes a rotating rod 701, a friction resistance block 702, a second gear 703 and a rotating handle 704, and the friction resistance block 702, the second gear 703 and the rotating handle 704 are sequentially arranged on the outside of the rotating rod 701 from the middle to both ends;

[0030] The rotating handle 704 is rotated to drive the rotating rod 701 to rotate. The friction between the rotating rod 701 and the friction resistance block 702 prevents the rotating rod 701 from automatically rotating. When the rotating rod 701 rotates, the second gear 703 is driven to rotate.

[0031] like Figure 4 As shown, the cooling assembly 8 includes a condensing unit 801 and a condensing tube 802, and the lower end of the condensing unit 801 is connected to the condensing tube 802;

[0032] The condensing unit 801 and the condensing tube 802 can dissipate heat at the contact point between the rotating block 402 and the friction block 501, thereby facilitating the friction block 501 to maintain a low temperature and preventing the friction block 501 from being worn out due to overheating during operation, thereby affecting the load value applied by the equipment and thus affecting the detection effect of the equipment.

[0033] Working principle: first install the motor 3 on the sliding block 201, and push the motor 3 into the equipment by relying on the sliding structure between the sliding block 201 and the sliding track 202, so that the rotating end of the motor 3 is inserted into the connecting head 401 for connection. At this time, turn on the motor 3, and drive the rotating block 402 to rotate through the connecting head 401 to perform durability testing. The staff can drive the rotating rod 701 to rotate by rotating the rotating handle 704, and the friction between the rotating rod 701 and the friction resistance block 702 prevents the rotating rod 701 from rotating automatically. When the rotating rod 701 rotates, it will drive the second gear 703 to rotate, thereby driving the threaded rod 506 supported by the support frame 6 to rotate through the transmission between the second gear 703 and the first gear 507, and the threaded rod 506 and the threaded rod 506 are connected to the threaded rod 506. The threaded connection between the threaded sleeve 504 allows the position of the threaded sleeve 504 to be controlled when the threaded rod 506 rotates, thereby controlling the degree of compression of the elastic block 508 by the threaded sleeve 504 and controlling the force applied by the elastic block 508 to the extrusion block 502, thereby controlling the rotational resistance of the rotating block 402 through the friction block 501, so that the device can control the load when the motor 3 rotates. When the device is working, the contact between the rotating block 402 and the friction block 501 can be dissipated through the condensing unit 801 and the condensing tube 802, so that the friction block 501 can be kept at a low temperature. The friction block 501 causes greater wear due to overheating during work, and the fan 9 can facilitate the diffusion of the cold air generated by the condensing tube 802, thereby making it easier to cool the friction block 501.

[0034] 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.
