DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figures 1 to 3 As shown, the utility model provides a high and low temperature test chamber, including a test chamber body 1, moving wheels 2 and a movable door 3. The moving wheels 2 are fixedly installed at the four corners of the bottom of the test chamber body 1, and the movable door 3 is movably installed on the left side of the front side of the test chamber body 1 through hinges. The bottom of the inner wall of the test chamber body 1 is movably connected to a rack 4, the rear side of the inner wall of the test chamber body 1 is fixedly connected to a connecting mechanism 5, and the left and right sides of the rack 4 are fixedly connected to guide mechanisms 6.

[0023] refer to Figure 3The connecting mechanism 5 includes a wedge-shaped frame 51, and two connecting grooves 52 are opened on the front side of the wedge-shaped frame 51. The rear side of the storage rack 4 is fixedly connected to two connecting columns 53, and the surfaces of the two connecting columns 53 are movably connected to the inner walls of the connecting grooves 52.

[0024] As a technical optimization solution of the present invention, by setting up a connecting mechanism 5, the connecting groove 52 can be used to enable the wedge-shaped frame 51 to movably limit the connecting column 53, and the movably limited connecting column 53 can movably limit the storage rack 4, so that the rear side of the storage rack 4 can move along the front side of the wedge-shaped frame 51.

[0025] refer to Figure 2 and Figure 3 The guide mechanism 6 includes a connecting rod 61, and the surface of the other end of the connecting rod 61 is movably connected to a movable ring 62. Guide grooves 63 are provided on the left and right sides of the inner wall of the test box body 1, and the surface of the movable ring 62 is movably connected to the inner wall of the guide groove 63.

[0026] As a technical optimization solution of the present invention, by setting up a guide mechanism 6, the up and down movement of the storage rack 4 can drive the connecting rod 61 to move, and the movement of the connecting rod 61 can drive the movable ring 62 to slide inside the guide groove 63. The guide groove 63 can improve the stability of the up and down movement of the movable ring 62, the connecting rod 61 and the storage rack 4.

[0027] refer to Figure 3 A fixing rod 7 is fixedly connected to the top of the left front side of the inner wall of the test box main body 1, and the other end of the fixing rod 7 is fixedly connected to the top of the right front side of the inner wall of the test box main body 1. Soft steel wire ropes 8 are wrapped around the surfaces of both ends of the connecting rod 61, and the surfaces of the soft steel wire ropes 8 are movably connected to the surfaces of the fixing rod 7.

[0028] As a technical optimization solution of the present invention, by setting a fixed rod 7 and a soft steel wire rope 8, the fixed rod 7 can guide the soft steel wire rope 8, and the fixed rod 7 is used to facilitate the movement of the connecting rod 61 by pulling the soft steel wire rope 8.

[0029] refer to Figure 1 and Figure 2 A motor 9 is fixedly installed on the rear side of the top right side of the test box body 1, and the output end of the motor 9 is fixedly connected to the winding rod 10. The other end of the winding rod 10 is movably connected to the top of the left rear side of the inner wall of the test box body 1 through a bearing, and the end of the soft steel wire rope 8 away from the connecting rod 61 is wrapped around the surface of the winding rod 10.

[0030] As a technical optimization solution of the present invention, by setting up a motor 9 and a winding rod 10, by starting the motor 9, the output end of the motor 9 can drive the winding rod 10 to rotate, and the rotation of the winding rod 10 can reel the soft steel wire rope 8.

[0031] refer to Figure 1 and Figure 3 The surface of the connecting column 53 away from one end of the shelf 4 is fixedly connected to the limit ring 11, and the front side of the movable door 3 is inlaid with an observation window 12.

[0032] As a technical optimization solution of the present invention, by providing a limit ring 11 and an observation window 12, the limit ring 11 can movably limit the connecting column 53, thereby preventing the connecting column 53 from separating from the wedge frame 51, and the observation window 12 facilitates the user to observe the test results.

[0033] When the test product is put on the top of the rack 4, the movable door 3 is opened first and the test product is placed on the top of the rack 4. Then the movable door 3 is closed and the test box body 1 is started to perform a performance test. After the test is completed, the movable door 3 is opened first, and then the motor 9 is started to drive the winding rod 10 to rotate. The winding rod 10 rotates to reel in the soft steel wire rope 8. At this time, the soft steel wire rope 8 can pull the connecting rod 61. The movement of the connecting rod 61 can drive the rack 4 to move upward. At the same time, the connecting column 53 and the limiting ring 11 limit the wedge frame 51, so that the rear side of the rack 4 can move upward along the front side of the wedge frame 51. When the rack 4 moves upward to the maximum limit, the test product on the top of the rack 4 is away from the interior of the test box body 1. At this time, the user can take it out from the top of the rack 4, thereby preventing the user's hands from touching the inner wall of the test box body 1 and causing damage.

[0034] To sum up: this high and low temperature test chamber, by providing a storage rack 4, can move the storage rack 4 to the front side to drive the test product placed on the top to move to the outside of the test chamber body 1, thereby solving the problem that the test temperature inside the test chamber body is maintained for a long time. The user needs to take the test product out of the inside of the test chamber body after the test. If the user is not stable enough when taking it out, it is easy for the user's hand to come into contact with the inner wall of the test chamber body, which can easily cause burns or frostbite.
