[0019] 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.

[0020] Please see Figure 1-5This utility model provides a technical solution: an odor detection device for a cold chain truck compartment, comprising a compartment 1, connecting frames 2 fixedly installed on the left and right sides of the inner wall of the compartment 1, a motor 3 fixedly installed on the surface of the connecting frame 2 near the opening of the compartment 1, a screw 4 fixedly connected to the output end of the motor 3, a ball nut seat 5 threadedly fitted on the outer wall of the screw 4, a connecting plate 6 fixedly connected to the outer wall of the ball nut seat 5, and a mounting shell 9 fixedly connected to the other side of the connecting plate 6 connected to the ball nut seat 5, with a storage groove 10 formed on one side of the inner wall of the mounting shell 9. A spring 11 is installed inside the storage slot 10. A locking block 12 is fixedly connected to the other end of the spring 11, which is connected to the mounting shell 9. A mounting block 14 is embedded in the opening of the mounting shell 9. A slot 15 is formed on one side surface of the mounting block 14. A detector 16 is fixedly installed on the opposite side of the mounting shell 9, embedded in the mounting block 14. Through the arrangement of the carriage 1, connecting frame 2, motor 3, screw 4, ball nut seat 5, connecting plate 6, mounting shell 9, storage slot 10, spring 11, locking block 12, connecting rod 13, mounting block 14, slot 15, and detector 16, in... When installing detector 16, align mounting block 14 with the opening of mounting housing 9 and insert it. When mounting block 14 is fully inserted into mounting housing 9, locking block 12 will be pushed into slot 15 by the elastic force of spring 11. At this time, mounting block 14 will be fixed in mounting housing 9, and detector 16 will be fixedly installed at one end of mounting housing 9. To remove detector 16, simply pull connecting rod 13. Connecting rod 13 can pull locking block 12 into storage slot 10. At this time, locking block 12 will leave slot 15, and mounting block 14 can be removed from mounting housing 9. The installation and removal of the detector 16 are very quick and convenient. When detecting odors in the compartment 1, the motor 3 causes the screw 4 to rotate back and forth in both directions. At this time, the ball nut seat 5 will move back and forth horizontally through the connecting plate 6 and the mounting shell 9. The detector 16 will be moved back and forth horizontally in the compartment 1, which can automatically and comprehensively detect odors in the compartment 1. When the odor is too strong, the detector 16 will sound an alarm, and the driver can promptly disperse the odor in the compartment 1 to prevent the odor from being too strong and affecting the quality of subsequent goods.

[0021] Furthermore, a limiting block 7 is fixedly installed on the opposite side of the ball nut seat 5 connected to the connecting plate 6, and a limiting groove 8 is opened on the inner wall of the connecting frame 2 facing the opening. With the setting of the ball nut seat 5, when the screw 4 reciprocates in both directions, the ball nut seat 5 will carry the connecting plate 6 to reciprocate horizontally, so that the detector 16 can automatically reciprocate horizontally in the carriage 1.

[0022] Furthermore, the limiting block 7 forms a sliding structure with the connecting frame 2 through the limiting groove 8. With the setting of the limiting block 7 and the limiting groove 8, when the limiting block 7 slides in the limiting groove 8, the limiting block 7 can assist and limit the movement of the ball nut seat 5.

[0023] Furthermore, a connecting rod 13 is fixedly connected to the side surface of the locking block 12 that is connected to the spring 11. With the setting of the spring 11, when the locking block 12 is not under force, the elastic force of the spring 11 can bring the locking block 12 back to its original position, at which time the locking block 12 can be locked into the slot 15.

[0024] Furthermore, one end of the connecting rod 13 is fixedly connected to the locking block 12, and the other end passes through the mounting shell 9. By setting the connecting rod 13, when the detector 16 is disassembled, pulling the connecting rod 13 can pull the locking block 12 into the storage slot 10, at which time the mounting block 14 can leave the mounting shell 9.

[0025] Furthermore, the size of the card block 12 matches that of the card slot 15. The card block 12 forms a telescopic structure with the mounting shell 9 through the spring 11. With the setting of the card block 12 and the card slot 15, when the card block 12 enters the card slot 15, the mounting block 14 will be fixed in the mounting shell 9, and the detector 16 will be fixedly installed at one end of the mounting shell 9. The operation is simple and convenient.

[0026] Furthermore, the opening end of the carriage 1 is connected to a door 17 by a bearing. Two sets of doors 17 are symmetrically arranged around the central axis of the carriage 1. The symmetrical arrangement of the doors 17 makes opening and closing very convenient.

[0027] Working principle: When installing detector 16, align mounting block 14 with the opening of mounting shell 9 and insert it. When mounting block 14 is fully inserted into mounting shell 9, locking block 12 will be pushed into locking slot 15 by the elastic force of spring 11. At this time, mounting block 14 will be fixed in mounting shell 9, and detector 16 will be fixedly installed at one end of mounting shell 9. When detector 16 needs to be removed, simply pull connecting rod 13. Connecting rod 13 can pull locking block 12 into storage slot 10. At this time, locking block 12 will leave locking slot 15, and mounting block 14 can leave mounting shell 9. When detecting odor in the compartment 1, motor 3 causes screw 4 to reciprocate in both directions. At this time, ball nut seat 5 will carry mounting shell 9 to reciprocate horizontally through connecting plate 6. Detector 16 will be carried to reciprocate horizontally in the compartment 1, which can automatically and comprehensively detect odor in the compartment 1.

[0028] 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.
