Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0023] A safety locking component for a rotational molding machine heating chamber, including a positioning substrate 1 and a heating chamber 2, characterized in that: a heating cavity 3 is provided inside the heating chamber 2, two groups of electric opening and closing doors 4 are installed on one side of the heating chamber 2, and a power mechanism 5 is installed on the top of the heating chamber 2 between the two groups of electric opening and closing doors 4. The power mechanism 5 is the core component for controlling the opening and closing of the electric opening and closing doors 4. It is usually composed of a motor, a transmission device, a control system, etc. The motor provides power, the transmission device transmits the power to the electric opening and closing doors 4, and the control system is responsible for receiving instructions and controlling the operation of the motor. The control system receives instructions from the operator (such as buttons, switches, etc.) or signals from a preset program, and decides the action of the electric opening and closing doors 4 according to the instruction content. The control system controls the operation of the motor, and realizes the opening and closing of the electric opening and closing doors 4 through the forward and reverse rotation of the motor. The power of the motor is transmitted to the electric opening and closing doors through a transmission device (such as gears, chains, belts, etc.). The design of the transmission device should ensure that the two groups of electric opening and closing doors 4 can move synchronously and smoothly;

[0024] On one side wall of each of the two sets of electric opening and closing doors 4, there are fixedly connected fixing blocks 6 respectively. On both side walls of the heating chamber 2, there are fixedly installed mounting blocks 7 corresponding to the fixing blocks 6 respectively. On one side wall of each of the two sets of mounting blocks 7, there are positioning components 8 which cooperate with the fixing blocks 6 to lock the electric opening and closing doors 4. By setting the cooperation of the electric opening and closing doors 4, the power mechanism 5, the fixing blocks 6, the mounting blocks 7 and the positioning components 8, when the two sets of electric opening and closing doors 4 are closed, the fixing blocks 6 can be locked and positioned by the positioning components 8, so as to achieve the effect of locking the two sets of electric opening and closing doors 4, ensure that the electric opening and closing doors 4 can be firmly locked, ensure that when the heating chamber 2 is working, the electric opening and closing doors 4 will not be accidentally opened, and at the same time, the heat inside the heating chamber 2 can be prevented from flowing out through the gaps of the electric opening and closing doors 4, avoid heat waste, and improve the working efficiency of the heating chamber 2 of the rotational molding machine;

[0025] The positioning component 8 includes two sets of fixed sleeves 801. Inside each of the two sets of fixed sleeves 801, there is a locking pin 802 slidably inserted. One end of each of the two locking pins 802 penetrates through the mounting block 7 and is inserted into the inside of the fixing block 6. The other ends of the two locking pins 802 are fixedly connected with a pull plate 803. There are also two sets of locking springs 9. One end of each of the two sets of locking springs 9 is fixedly connected to one side wall of the pull plate 803. The other ends of the two sets of locking springs 9 are respectively fixedly connected to one end of the two sets of fixed sleeves 801, and the two sets of locking springs 9 are respectively sleeved on the outer walls of the two locking pins 802. On one side wall of the fixing block 6, there are two positioning blind holes 10 adapted to one end of the locking pin 802. One end of each of the two locking pins 802 is inserted into the two positioning blind holes 10 respectively;

[0026] Specifically, when the two sets of electric opening and closing doors 4 are closing, first pull the pull plate 803, which can drive the locking pin 802 to move. At this time, the locking spring 9 is in a stretched state. When the two sets of electric opening and closing doors 4 are closed and the positioning blind hole 10 on one side of the fixing block 6 is aligned with one end of the locking pin 802, release the pull plate 803, and use the pulling force of the locking spring 9 to position the fixing block 6, so as to achieve the effect of locking and positioning the two sets of electric opening and closing doors 4, ensure that the electric opening and closing doors 4 can be firmly locked, ensure that when the heating chamber 2 is working, the electric opening and closing doors 4 will not be accidentally opened, and at the same time, the heat inside the heating chamber 2 can be prevented from flowing out through the gaps of the electric opening and closing doors 4, avoid heat waste, and improve the working efficiency of the heating chamber 2 of the rotational molding machine;

[0027] On one side wall of the heating chamber 2, an L-shaped limiting plate 11 is fixedly installed. The bottoms of the two groups of electric opening and closing doors 4 are both slidably connected to the L-shaped limiting plate 11. Through its specific shape and installation position, the L-shaped limiting plate 11 can effectively limit the movement range of the electric opening and closing doors 4, ensuring that the electric opening and closing doors 4 can accurately reach the predetermined position when closed, avoiding potential safety hazards caused by excessive movement or incomplete movement. By restricting the movement range of the electric opening and closing doors 4, the L-shaped limiting plate 11 can prevent the electric opening and closing doors 4 from colliding or rubbing against other parts of the heating chamber 2 when closed, thereby reducing the risk of equipment damage. At the same time, since the electric opening and closing doors 4 can be accurately and stably closed, the overall airtightness of the heating chamber 2 is improved, which helps to maintain the stability of the temperature and humidity inside the heating chamber 2, improving production efficiency and product quality;

[0028] On the inner top and inner bottom of the heating chamber 2, partition plates 12 are respectively fixedly connected. The two groups of partition plates 12 are both located on one side of the electric opening and closing doors 4. By setting the partition plates 12, it is beneficial to improve the airtightness of the electric opening and closing doors 4, further reducing the heat loss inside the heating cavity 3 and improving the heating efficiency of the heating chamber 2;

[0029] On one side of one group of electric opening and closing doors 4, a first semi-circular hole 13 is provided. On one side of the other group of electric opening and closing doors 4, a second semi-circular hole 16 adapted to the first semi-circular hole 13 is provided. The first semi-circular hole 13 and the second semi-circular hole 16 can be combined into a complete through hole, reserving space for the rotating shaft of the rotational molding machine;

[0030] On the top of the positioning base plate 1, two groups of electric slide rails 14 are fixedly connected. The tops of the two groups of electric slide rails 14 are respectively slidably connected with sliders 15. The tops of the two groups of sliders 15 are both fixedly connected to the bottom of the heating chamber 2. By setting the electric slide rails 14 and the sliders 15 to cooperate, the position of the heating chamber 2 can be moved, facilitating docking with the rotational molding machine.

[0031] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
