[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1:

[0023] Please refer to the following: Figures 1-6 This utility model provides a technical solution: a temperature resistance testing device for an automatic brake adjustment arm of an automobile, including a test box 1 and several hanging rings 2. A rotating groove 3 is provided on one side of each hanging ring 2, and a rotating ring 4 is rotatably connected to the rotating groove 3. A fixing block 5 is fixedly connected to the end of the rotating ring 4 away from the rotating groove 3. A slot is provided on the outer surface of each hanging ring 2, and movable rods 6 are movably inserted into both outer surfaces of each hanging ring 2. A limiting block 7 is fixedly connected to one side of the movable rod 6 inside the hanging ring 2. A spring 8 is fixedly connected between the limiting block 7 and the inner wall of the rotating ring 4, and the spring 8 is sleeved on the outer surface of the movable rod 6. Specifically, [further details to be added]. The eyelet of the brake adjusting arm to be tested is fitted onto the hanging ring 2. After the fitting is complete, force is applied to the rotating ring 4, causing the rotating ring 4 to rotate at the rotating groove 3. The fixing block 5 is inserted into the slot, and the fixing block 5 presses against the limiting block 7, causing the spring 8 to deform. When the limiting block 7 contacts the limiting groove, the spring 8 returns to its original position, allowing the limiting block 7 to be inserted into the limiting groove. The upper end of the brake adjusting arm on the hanging ring 2 is limited by the rotating ring 4. The test chamber 1 is heated by the heating tube 16 to measure the temperature of the brake adjusting arm, thereby limiting the brake adjusting arm and increasing the stability of the brake adjusting arm during temperature measurement.

[0024] In this embodiment, a rotating shaft 9 is rotatably connected to the inner surface of the test chamber 1. A motor 18 is fixedly installed on the left outer surface of the test chamber 1. The output end of the motor 18 is fixedly connected to the rotating shaft 9. Two sets of vertical plates 10 arranged symmetrically on the outer surface of the rotating shaft 9 are fixedly sleeved. Each set of vertical plates 10 consists of four plates arranged in a circular array. A support shaft is fixedly connected between each set of four vertical plates 10. A rotating sleeve 11 is provided on the outer surface of the support shaft. A connecting shaft 12 is fixedly connected to the outer surface of each rotating sleeve 11. Several hanging rings 2 are fixedly connected to the outer surface of the connecting shaft 12. Specifically, when the motor 18 is working, the motor 18 drives the rotating shaft 9 to rotate. The rotation of the rotating shaft 9 causes the vertical plates 10 to rotate. The vertical plates 10 drive the support shaft to rotate, causing the connecting shaft 12 to rotate. This causes the hanging rings 2 on the multiple connecting shafts 12 to rotate. The hanging rings 2 drive the brake adjustment arm to rotate, thereby causing the brake adjustment arm to rotate inside the test chamber 1. This allows the brake adjustment arm to be heated evenly, thereby improving the temperature measurement effect of the brake adjustment arm.

[0025] In this embodiment, a base box 13 is fixedly connected to the bottom outer surface of the test chamber 1. A partition 14 is installed inside the base box 13. Multiple fans 15 are fixedly installed on the bottom outer surface of the base box 13. Multiple heating tubes 16 are installed on the top outer surface of the base box 13 and the inner wall of the test chamber 1. Specifically, the heating tubes 16 heat the inside of the test chamber 1, and the fans 15 generate airflow to blow hot air into the test chamber 1, increasing the airflow speed and making the inside of the test chamber 1 heat up quickly.

[0026] In this embodiment, the outer surfaces of the front and rear sides of the limiting block 7 are both smooth and inclined. Specifically, by setting the limiting block 7 with a smooth and inclined surface, when the fixing block 5 contacts the limiting block 7, force is applied to the fixing block 5, which can squeeze the limiting block 7 and compress the spring 8.

[0027] In this embodiment, two counterweights 17 are fixedly connected to the outer surface of the connecting shaft 12 in a symmetrical arrangement. Specifically, the counterweights 17 enable the connecting shaft 12 to always remain vertically downward.

[0028] In this embodiment, the partition 14 is grid-shaped, and the bottom outer surface of the bottom box 13 is provided with several through holes. Specifically, by setting the grid-shaped partition 14, the airflow blown out by the fan 15 can pass through the partition 14, and by setting the through holes, the fan 15 can form effective convection.

[0029] Working principle: In use, the eye of the brake adjustment arm to be tested is placed on the hanging ring 2. After the arm is placed, force is applied to the rotating ring 4, causing the rotating ring 4 to rotate at the rotating groove 3. The fixing block 5 is inserted into the slot, and the fixing block 5 presses the limiting block 7, causing the spring 8 to deform. When the limiting block 7 contacts the limiting groove, the spring 8 returns to its original position, allowing the limiting block 7 to be inserted into the limiting groove. The upper end of the brake adjustment arm on the hanging ring 2 is limited by the rotating ring 4. The test chamber 1 is heated by the heating tube 16 to measure the temperature of the brake adjustment arm, thereby limiting the brake adjustment arm and increasing the stability of the brake adjustment arm during temperature measurement.

[0030] During temperature measurement, the motor 18 operates, driving the rotating shaft 9 to rotate. The rotation of the rotating shaft 9 causes the vertical plate 10 to rotate, which in turn drives the support shaft to rotate the connecting shaft 12. This causes the hanging rings 2 on the multiple connecting shafts 12 to rotate, which in turn drives the brake adjustment arm to rotate. As a result, the brake adjustment arm rotates within the test chamber 1, ensuring that it is heated evenly and thus improving the temperature measurement effect on the brake adjustment arm.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
