Background technique

In the use of the freezer, the freezer door needs to be opened and closed frequently. In order to ensure the stability of the mechanical structure of the freezer door switch during the long-term use, there is a freezer door life test step in the product test of the freezer. It uses a device to Simulate the opening and closing operation of the refrigerator door for testing.

Existing horizontal freezer door tests are all a single controlled opening or closing of the freezer door at 0-90 degrees or above, which cannot truly obtain the real effect of the freezer in practical applications; When the height of the door body of the vertical freezer is inconsistent, adjust the height of the swing arm and test from the left and right directions and the front and back of the drawer.

Utility model content

The purpose of the utility model is to provide a horizontal freezer door body life testing machine that imitates the action habit of opening and closing cabinet doors during actual operation of each user.

In order to achieve the above object, the utility model adopts the following technical solutions:

It includes a machine base plate, one side of the machine base plate is connected with a freezer fixing frame, an electric control box is installed on the machine base plate, and one side of the electric control box is provided with a pneumatic door closing device motor lifting seat, Pneumatic door closing device The motor lifting seat is connected with a pneumatic door closing device, a rope rolling clutch device is installed on the base, and a door-opening automatic controlled rope belt is installed in the rope rolling clutch device.

The lifting seat of the pneumatic door closing device is provided with one or more pulleys, and the automatically controlled rope for opening the door passes through the pulleys to connect the rope rolling clutch device and the refrigerator door.

The lifting seat of the pneumatic door closing device is provided with a vertically moving guide post.

The freezer fixing frame includes a support frame and two limit rods vertically installed on the support frame.

The bottom of the machine base is provided with adjustable universal casters.

The sensor angle fixed adjustment plate is arranged on a support, and the controlled angle sensor adjustment seat is provided at the bottom of the support.

The pulley is arranged on the rope transition wheel seat.

The horizontal freezer door life testing machine of the utility model controls the controlled angle of the door opening and closing device of the horizontal freezer, so as to truly imitate the operation under various usage conditions and achieve a completely real test effect. The door opening angle is 90 degrees. When opening, the opening angle is between 0 degrees and 60-75 degrees. The movement process of the door should be a controlled process, and the process of opening to 75 degrees is a free movement process. Opening should occur at 3/4 of the opening cycle; when closing, the movement of the door should be a controlled process from the opening angle of 90 degrees to 40-70 degrees, and then the process of closing to 0 degrees should be During free movement, close the door as normal.

Description of drawings

Fig. 1 is the three-dimensional structural representation of the utility model;

Fig. 2 is a schematic diagram of the three-dimensional structure of the utility model from another angle.

The purpose, functions and advantages of the utility model will be further described in conjunction with the embodiments and with reference to the accompanying drawings.

Detailed ways

As shown in Figures 1 and 2, the horizontal freezer door life testing machine of this embodiment includes a machine base 1, which is a horizontal plate structure, and one side of the machine base 1 is connected to a useful To fix the freezer fixing frame 2 of the freezer to be checked, an electric control box 3 is installed on the base plate 1 of the machine, and one side of the electric control box 3 is provided with a pneumatic door closing device motor lifting seat 4, and the pneumatic door closing device motor lifts The seat 4 is connected with a pneumatic door closing device 5, a rope rolling clutch device 6 is installed on the base 1, an automatic door opening control rope 7 is installed in the rope rolling clutch device 6, and a sensor angle is fixedly adjusted on the refrigerator fixing frame 2. plate 8.

In order to facilitate the controlled sliding back and forth of the automatic door-opening controlled rope belt 7, one or more pulleys 9 are provided on the lifting seat 4 of the pneumatic door-closing device in this embodiment, and the automatic door-opening controlled rope belt 7 passes through the pulleys. 9 connect rope belt rolling clutch device 6 and refrigerator door 10. The pulley 9 is located on the rope transition wheel base 11 .

In order to facilitate the vertical height adjustment of the pneumatic door closing device, the lifting seat 4 of the pneumatic door closing device described in this embodiment is provided with a vertically moving guide post 12 .

The freezer fixing frame 2 described in this embodiment includes a support frame 21 and two stop rods 22 vertically installed on the support frame.

In order to facilitate the movement of the entire device, in this embodiment, adjustable universal casters 13 are provided at the bottom of the machine base 1 .

The sensor angle fixed adjustment plate 8 is arranged on a bracket 14 , and the bottom of the bracket 14 is provided with a controlled angle sensor adjustment seat 15 .

When the machine is working automatically, the automatic door-opening controlled rope is driven by the rope clutch device, and the rope is contracted through the transition wheel to pull up the refrigerator door. When the adjusted door-opening controlled angle sensor senses that the door is opened to When the angle is adjusted, the rope no longer exerts force, and the inertia of the door body continues to open to 90 degrees, and then the 90-degree sensor confirms that the door body reaches 90 degrees, and the pneumatic door closing device pushes forward to close the door. When the adjusted controlled closing angle The sensor detects the door body, the pneumatic door closing device no longer pushes forward but resets backward, but the door body relies on inertia until it closes, and this reciprocating cycle, the electric control box panel has text displaying the number of tests and related parameters, which can be Set the time and times of opening and closing the door directly on the screen. During the whole test process, the movement process of the door should be a controlled process, and then the process when it is opened to 75 degrees is a free movement process, and the opening of the door should occur at 3/4 of the opening period; when it is closed, from When the opening angle is between 90 degrees and 40-70 degrees, the movement of the door should be a controlled process, and then the process of closing to 0 degrees should be a free movement process, and the door should be closed according to normal conditions.

The above descriptions are only preferred embodiments of the present utility model, and are not therefore limiting the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made by using the specification of the utility model and the contents of the accompanying drawings may be directly or indirectly used in Other relevant technical fields are all included in the patent protection scope of the present utility model in the same way.
