Abstract
Description
Technical Field
[0001] This utility model relates to the field of pre-packaged food processing technology, and more specifically, to a pre-packaged food freezing device. Background Technology
[0002] Prepackaged food refers to food that is pre-quantitatively packaged or prepared in packaging materials and containers; including pre-quantitatively packaged food and food pre-quantitatively prepared in packaging materials and containers with uniform quality or volume markings within a certain quantity limit. It means that after packaging, it has a definite quantity value. This definite quantity value should be "with uniform quality or volume markings within a certain quantity limit." When processing prepackaged food, freezing equipment is required to freeze it to avoid damage.
[0003] However, in actual use, most existing pre-packaged food freezing devices are freezers, and the doors of most existing freezers need to be opened manually without a self-locking mechanism. This means that after the door is opened, it needs to be held down by a person to prevent it from falling. In addition, the door is heavy, which not only consumes the user's physical strength but also makes it inconvenient for the user to take out the pre-packaged food inside the freezer. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a pre-packaged food freezing device to solve the problem that the prior art does not have a self-locking structure for the freezer door, which means that after the door is opened, it needs to be continuously held by manpower to prevent the door from falling down, making it inconvenient to take out the pre-packaged food in the freezer.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a pre-packaged food freezing device, including a freezer for freezing pre-packaged food, two sets of cabinet doors are symmetrically arranged on the freezer along the left and right direction, and mounting frames are fixed on both sides of the top back of the freezer. Each set of mounting frames is rotatably equipped with a fixed shaft, and two sets of L-shaped frames with one end fixed to the cabinet door are symmetrically fixed on each set of fixed shafts. A vertical plate is fixed at the bottom of each set of mounting frames, and an anti-fall component for use with the cabinet door is provided on the vertical plate.
[0006] The anti-fall component includes a reinforcing pull plate fixed to each set of fixed shafts. A sliding plate is slidably mounted on the back of the vertical plate. Multiple sets of first pawls are sequentially fixed on one side of the sliding plate along the vertical direction. A push plate is rotatably mounted on one end of the reinforcing pull plate, and one end of the push plate is rotatably mounted on the sliding plate. An installation shaft is rotatably mounted on the bottom of the back of the vertical plate. A second pawl that meshes with the first pawl is fixed at one end of the installation shaft. An auxiliary spring is fixed at the bottom of the second pawl. A protrusion is fixed at the bottom end of the auxiliary spring and the protrusion is fixed on the vertical plate. An auxiliary moving structure that works in conjunction with the second pawl is provided on the freezer.
[0007] The auxiliary moving structure includes a fixed frame fixed to one end of the mounting shaft and located on the back of the second pawl. A sliding seat is inserted inside the fixed frame. A lifting rope is fixed to the end of the sliding seat away from the fixed frame. Guide pipes are fixed to the top of both sides of the freezer. One end of the lifting rope passes through the guide pipe and is fixed with a lifting plate. The end of the guide pipe located on the front of the freezer has a vertical upward structure.
[0008] The vertical plate has a limit plate fixed to its back, and the sliding plate has a limit track for the limit plate to slide. The limit plate has an overall T-shaped structure.
[0009] Each set of mounting frames has a limiting plate attached to both sides of its bottom for use with an L-shaped frame, and one end of the limiting plate is fixed to the freezer.
[0010] The reinforcing plate has an upwardly inclined structure.
[0011] The bottom end of the L-shaped frame has an arc-shaped structure, and there is a gap between the L-shaped frame and the limiting plate.
[0012] Compared with the prior art, the beneficial effects of this utility model are: In the above solution, by setting an anti-fall component, the fixed shaft will rotate when the cabinet door flips upward, thereby changing the angle of the reinforcing pull plate. With the assistance of the push plate, the position of the sliding plate can be changed synchronously. The design of the auxiliary spring, the second pawl, and the first pawl, together with the first and second pawls with opposite claw directions, can quickly form a structure that restricts the movement direction of the sliding plate, thereby limiting the flip angle of the cabinet door. This ensures that the cabinet door will automatically lock after flipping upward, preventing it from falling downward. The design of the auxiliary moving structure can quickly release the restriction on the sliding plate and the cabinet door, facilitating the rapid descent and reset of the auxiliary cabinet door. At this time, the cabinet door with a self-locking structure will not fall automatically when it is raised to any angle within the maximum angle range, improving safety and making it convenient for users to take out and put in pre-packaged food in the freezer.

[0015] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.
[0016] Example 1: Please refer to Figures 1 to 5 This utility model provides a technical solution: a pre-packaged food freezing device, including a freezer 1 for freezing pre-packaged food. Two sets of cabinet doors 2 are symmetrically arranged on the freezer 1 along the left and right directions. Mounting frames 3 are fixed on both sides of the top back of the freezer 1. Each set of mounting frames 3 is rotatably equipped with a fixed shaft 4. Two sets of L-shaped frames 5, one end of which is fixed to the cabinet door 2, are symmetrically fixed on each set of fixed shaft 4. Limiting plates 6, which cooperate with the L-shaped frames 5, are attached to both sides of the bottom of each set of mounting frames 3. One end of the limiting plate 6 is fixed to the freezer 1. The design of the limiting plate 6 can limit the swing angle of the L-shaped frame 5, thereby controlling the flip angle of the cabinet door 2 and preventing the cabinet door 2 from flipping excessively, which would affect normal use. A vertical plate 9 is fixed to the bottom of each set of mounting frames 3. The bottom end of the L-shaped frame 5 has an arc-shaped structure. There is a gap between the L-shaped frame 5 and the limiting plate 6. The design of the gap, combined with the arc-shaped structure, is to prevent the L-shaped frame 5 from flipping and to prevent the limiting plate 6 from interfering with the normal rotation of the L-shaped frame 5.
[0017] The vertical plate 9 is equipped with an anti-fall component that works in conjunction with the cabinet door 2. The anti-fall component includes a reinforcing pull plate 7 fixed to each set of fixed shafts 4. The reinforcing pull plate 7 has an upward tilt structure to provide a certain amount of rotation space and prevent it from colliding with the vertical plate 9 when the cabinet door 2 is rotated to its maximum angle. A sliding plate 10 is slidably mounted on the back of the vertical plate 9. A limit plate 15 is fixed to the back of the vertical plate 9. The sliding plate 10 has a limit track 16 for the limit plate 15 to slide on. The limit plate 15 has a T-shaped structure. The design of the limit track 16 and the limit plate 15 can limit the sliding of the sliding plate 10 and prevent it from easily falling off. The vertical plate 9 improves the stability of the slide plate 10 during movement. Multiple sets of first pawls 11 are fixed sequentially along the vertical direction on one side of the slide plate 10. One end of the reinforcing pull plate 7 is rotatably equipped with a push plate 8, and one end of the push plate 8 is rotatably mounted on the slide plate 10. The bottom of the back of the vertical plate 9 is rotatably equipped with a mounting shaft 12. One end of the mounting shaft 12 is fixed with a second pawl 13 that meshes with the first pawls 11. The claws of the first pawls 11 and the second pawls 13 face opposite directions. The distance between two adjacent sets of first pawls 11 is sufficient for the second pawls 13 to swing outward. An auxiliary spring 14 is fixed to the bottom of the second pawl 13. A protrusion is fixed to the bottom end of the auxiliary spring 14 and the protrusion is fixed to the vertical plate 9.
[0018] When cabinet door 2 flips upward, fixed shaft 4 rotates accordingly, thereby changing the angle of reinforcing pull plate 7. With the assistance of push plate 8, the position of slide plate 10 can be changed synchronously. The design of auxiliary spring 14, second pawl 13 and first pawl 11, together with the first pawl 11 and second pawl 13 with opposite claw directions, can quickly form a structure that restricts the movement direction of slide plate 10, thereby limiting the flipping angle of cabinet door 2. This allows cabinet door 2 to automatically lock after flipping upward, preventing cabinet door 2 from falling downward.
[0019] Example 2: Based on Example 1, in order to quickly reset the cabinet door 2, which has swung upwards and locked itself, to close the top of the freezer 1, an auxiliary moving structure is needed to quickly release the engagement between the first pawl 11 and the second pawl 13. The freezer 1 is provided with an auxiliary moving structure that works in conjunction with the second pawl 13. The auxiliary moving structure includes a fixed frame 17 fixed to one end of the mounting shaft 12 and located on the back of the second pawl 13. A sliding seat 18 is inserted into the fixed frame 17. A lifting rope 19 is fixed to the end of the sliding seat 18 away from the fixed frame 17. Guide pipes 20 are fixed to the top of both sides of the freezer 1. One end of the lifting rope 19 passes through the guide pipe 20 and is fixed with a lifting plate 21. The end of the guide pipe 20 located on the front of the freezer 1 is vertically upward.
[0020] Using the guide pipe 20, the lifting rope 19 can be redirected, so that the user can quickly pull the sliding seat 18 using the lifting rope 19. In conjunction with its insertion into the fixed frame 17, the angle of the second pawl 13 can be quickly changed, so that the second pawl 13 can quickly disengage from the first pawl 11, releasing the locking state of the slide plate 10. This facilitates the quick release of the lock on the cabinet door 2, allowing the user to quickly close the cabinet door 2 that has swung upwards.
[0021] The working process of this utility model is as follows: When the user pulls the cabinet door 2 upwards, causing it to flip upwards, the fixed shaft 4 rotates accordingly, which in turn causes the reinforcing pull plate 7 to swing downwards. This, in conjunction with the movement of the push plate 8, pushes the sliding plate 10 downwards synchronously. Simultaneously, the elastic rebound of the auxiliary spring 14 continuously provides a pushing force to the second pawl 13, ensuring that as the sliding plate 10 moves downwards, the second pawl 13 continuously contacts and engages with the multiple sets of first pawls 11 on the sliding plate 10. Since the teeth of the first pawls 11 and the second pawl 13 face opposite directions, the second pawl 13 can control the movement direction of the first pawls 11. The system restricts the movement of the door 2 so that it can only move downwards with the slide plate 10. When moving upwards, the second pawl 13 automatically engages between the two adjacent sets of first pawls 11 to restrict its upward movement. This limits the position of the slide plate 10 and, consequently, the rotation angle of the cabinet door 2. The cabinet door 2 automatically locks after rotating upwards, preventing it from falling downwards. This facilitates the user's access to pre-packaged food in the freezer 1. With the cabinet door 2 featuring a self-locking structure, it will not automatically fall when raised to any angle within its maximum range, thus improving safety.
