[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0029] See also Figure 1-9A freezer provided by an embodiment of the present invention comprises a cabinet 1, a protective fence 2 and a U-shaped frame 4. The cabinet 1 is provided with an inspection window 11 and a heat dissipation window 12. The protective fence 2 is horizontally slidably connected to the cabinet 1. The protective fence 2 has a first disengagement position capable of disengaging from the cabinet 1 and a second disengagement position in an opposite direction in a horizontal sliding stroke relative to the cabinet 1. When the protective fence 2 is between the first disengagement position and the second disengagement position, the protective fence 2 has a fixed position capable of covering the inspection window 11. When the protective fence 2 is in a fixed position, the protective fence 2 can be locked and unlocked by the two first locking components 3; specifically, the first locking component 3 includes a slider 31 and a first elastic member 32, the slider 31 is vertically slidably connected to the cabinet 1, and the slider 31 is provided with an inclined surface 311 that abuts against the protective fence 2; the first elastic member 32 is used to drive the slider 31 to slide vertically, and the first elastic member 32 includes a first spring, one end of the first spring is connected to the cabinet 1, and the other end of the first spring is connected to the slider 31.

[0030] The U-shaped frame 4 is rotatably connected to the cabinet 1, and a partition net 81 is provided on the U-shaped frame 4. The U-shaped frame 4 has a covering position that can cover the heat dissipation window 12 in its rotational stroke relative to the cabinet 1. When the U-shaped frame 4 is in the covering position, the U-shaped frame 4 can be locked by the second locking assembly 5 and can be unlocked; when the protective fence 2 is switched from the fixed position to the second disengagement position, the protective fence 2 triggers the second locking assembly 5 to unlock. Specifically, the second locking assembly 5 includes a first slide plate 51 and a second elastic member 52. The first slide plate 51 is vertically slidably connected to the cabinet 1. The first slide plate 51 is provided with a plurality of plug rods 6 that are plugged into and matched with the U-shaped frame 4. The first slide plate 51 is provided with a wedge block 511 that abuts against the protective fence 2; the second elastic member 52 is used to drive the first slide plate 51 to vertically Sliding, the second elastic member 52 includes a second spring, one end of the second spring is connected to the first slide plate 51, and the other end of the second spring is connected to the cabinet body 1. The second locking assembly 5 also includes a second slide plate 53. The second slide plate 53 is vertically slidably connected to the cabinet body 1. The second slide plate 53 is provided with a plurality of plug rods 6 that are plugged and matched with the U-shaped frame 4. When the first slide plate 51 slides vertically, the second slide plate 53 is driven to slide relatively through the linkage assembly 7, wherein the linkage assembly 7 includes a two-way telescopic rod 71, a first hinged rod 72 and a second hinged rod 73, and the two-way telescopic rod 71 is rotatably connected in the cabinet body 1; one end of the first hinged rod 72 is hinged to the two-way telescopic rod 71, and the other end is hinged to the first slide plate 51; one end of the second hinged rod 73 is hinged to the two-way telescopic rod 71, and the other end is hinged to the second slide plate 53.

[0031] Compared with the prior art, the present invention provides a freezer. When the staff only performs regular inspections, the staff can first slide the slider 31 of the first locking assembly 3 near the first disengagement position vertically upward. After the slider 31 slides vertically upward to the point where it does not limit the protective fence 2, the worker can switch the protective fence 2 from the fixed position to the first disengagement position. When the protective fence 2 is in the first disengagement position, the protective fence 2 no longer covers the inspection window 11, and the inspection window 11 is now completely exposed to the outside. The staff can inspect the internal condenser, fan, etc. through the inspection window 11. In the process of switching the protective fence 2 from the first disengagement position to the fixed position, the protective fence 2 will be in contact with the inspection window 11 near the first disengagement position. The inclined surface 311 of the slider 31 of the first locking assembly 3 at a disengagement position abuts against the slider 31, causing the slider 31 to slide vertically upward. When the protective fence 2 slides to the fixed position, the slider 31 slides vertically downward under the elastic force of the first spring, abutting against the protective fence 2 to limit the protective fence 2. Since the contact surfaces between the two sliders 31 and the protective fence 2 are L-shaped, the two sliders 31 can fix the protective fence 2 more firmly. In addition, in the process of switching the protective fence 2 from the fixed position to the first disengagement position, the protective fence 2 can also stop sliding near a certain position of the first disengagement position. At this time, the protective fence 2 does not block the inspection window 11 and abuts against the slider 31, which is convenient for the worker to reset the protective fence 2.

[0032] If the staff needs to open the protective fence 2 and the U-shaped frame 4 when cleaning the fan, condenser tube, etc., the staff can unlock the first locking assembly 3 near the second disengagement position. During the unlocking process, the slider 31 of the first locking assembly 3 near the second disengagement position slides vertically upward, and the protective fence 2 slides toward the second disengagement position. In the process of switching the protective fence 2 from the fixed position to the second disengagement position, the protective fence 2 will trigger the wedge block 511 of the first slide plate 51 to abut, so that the first slide plate 51 can slide vertically upward. In the process of the first slide plate 51 sliding vertically upward, the insertion rod 6 on the first slide plate 51 will be disengaged from the insertion of the U-shaped frame. In the process of the first slide plate 51 sliding vertically upward, the first hinged rod 72 is pulled to enable the bidirectional telescopic rod 71 to rotate around the rotating axis in the middle of the bidirectional telescopic rod 71. The rotation of the bidirectional telescopic rod 71 enables the second hinged rod 73 to push the second slide plate 53 vertically relative to the first slide plate 51. The U-shaped frame 4 is then moved back and forth to the left and right sides of the protective fence 2. When the protective fence 2 is moved back and forth to the right and left sides of the protective fence 2, the protective fence 2 is moved back and forth to the right and left sides of the protective fence 2. When the protective fence 2 is moved back and forth to the right and left sides of the protective fence 2, the protective fence 2 is moved back and forth to the right and left sides of the protective fence 2. When the protective fence 2 is moved back and forth to the right and left sides of the protective fence 2, the protective fence 2 is moved back and forth to the right and left sides of the protective fence 2. When the protective fence 2 is moved back and forth to the right and left sides of the protective fence 2, the protective fence 2 is moved back and forth to the right and left sides of the protective fence 2. When the protective fence 2 is moved

[0033] By locking the protective fence 2 with the two first locking components 3 and locking the U-shaped frame 4 with the second locking component 5, the worker only needs to unlock one of the first locking components 3 and then move the protective fence 2 to expose the inspection window 11 when inspecting the fan, etc. If the worker needs to clean the fan, etc., the inspection window 11 is exposed to the outside by unlocking the other first locking component 3 and then moving the protective fence 2. During this process, the second locking component 5 is triggered to unlock by the protective fence 2, and the worker can rotate the U-shaped frame to clean the partition net 81 thereon, which not only facilitates the worker's work but also improves the worker's cleaning efficiency.

[0034] Among them, the U-shaped frame 4 is slidably connected to the mounting frame 8, and the partition net 81 is fixedly connected to the mounting frame 8. Each insertion rod 6 passes through the U-shaped frame 4 and is plugged into the mounting frame 8. The mounting frame 8 and the partition net 81 can be removed from the U-shaped frame to clean the partition net 81 more thoroughly.

[0035] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
