Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of cold chain transportation, and particularly relates to a heat preservation box. BACKGROUND

[0002] At present, many domestic companies have launched cold chain express services, and the main equipment is a heat preservation box. The launch of the cold chain express service is only a part of the application of the heat preservation box, and the heat preservation box is also widely used in daily life. For example, in hot summer, a heat preservation box can be used to cool beverages and food when going on a picnic, bringing a cool feeling to the family; in cold winter, a heat preservation box can be used to keep food warm, bringing warmth to the family; in a hospital, when a doctor needs to vaccinate a child, a heat preservation box can be used to store the vaccine in a suitable temperature range; when a pharmaceutical company transports a small amount of biological agents, a heat preservation box can also be used to maintain the activity of the biological agents; in addition, the heat preservation box can also be applied to other fields that require freezing or refrigeration.

[0003] The existing heat preservation boxes on the market usually use EPS foam as a heat preservation layer to increase the heat preservation time and make the heat preservation box portable. However, the existing heat preservation boxes usually have at least the following deficiencies:

[0004] 1) Most heat preservation boxes do not have a security function, and anyone can open them, so it is not convenient to store items that require security;

[0005] 2) The temperature sensing probe in the box is not fixed and scattered in the box, and lacks protection for the temperature sensing probe;

[0006] 3) Multiple heat preservation boxes are prone to collapse when stacked. SUMMARY

[0007] In view of the deficiencies in the related art, the present application provides a heat preservation box to at least solve the security function problem of the heat preservation box.

[0008] The present application provides a heat preservation box, comprising:

[0009] a box body having a containing cavity and a box opening for the goods to enter or exit the containing cavity;

[0010] a door cover rotatably connected to the box body for opening or closing the containing cavity;

[0011] a fingerprint lock for locking or unlocking between the door cover and the box body; the fingerprint lock comprises:

[0012] a lock shell installed at the box opening and close to the opening end of the door cover;

[0013] The lock bolt assembly comprises a rotating body and a lock bolt. The rotating body is rotationally connected in the lock shell. The lock bolt is slidingly connected in the rotating body in the direction perpendicular to the axial direction of the rotating body, so that the front end of the lock bolt extends out of the lock shell or retreats into the lock shell. The opening end of the door cover is concavely provided with a lock opening matched with the lock bolt. When the door cover is in the locked state with the box body, the lock bolt is inserted into the lock opening. When the door cover is opened, the door cover drives the lock bolt to rotate so that the lock bolt is separated from the lock opening. After the door cover is opened, the lock bolt is rotated to reset. When the door cover is closed, the door cover presses the lock bolt to retreat into the lock shell. After the door cover is closed, the front end of the lock bolt extends out of the lock shell to reset and is inserted into the lock opening.

[0014] The locking mechanism comprises a stop assembly and an actuating assembly. One end of the stop assembly abuts against the rotating body. When the actuating assembly is not actuated, the actuating assembly abuts against the stop assembly to stop the rotating body, so that the lock bolt does not rotate. When the actuating assembly is actuated, the actuating assembly no longer abuts against the stop assembly to release the stop of the rotating body, so that the lock bolt rotates under the driving of the door cover.

[0015] The fingerprint identification mechanism is used to identify fingerprint information. The fingerprint identification mechanism is electrically connected with the actuating assembly to control the actuation of the actuating assembly.

[0016] The above technical solution realizes the technical effect that the heat preservation box can be unlocked only after the fingerprint identification is performed by the setting of the fingerprint identification mechanism and the locking mechanism, so that the heat preservation box has a security function. The lock bolt is driven to rotate to realize the opening of the box by directly opening the door cover after the heat preservation box is unlocked by the fingerprint, and the lock bolt is driven to slide to realize the locking of the box by directly releasing the door cover when the door cover is closed, so that the opening and closing of the heat preservation box are more convenient and fast.

[0017] In some embodiments, the lock bolt assembly further comprises a reset torsional spring. One end of the reset torsional spring is connected with the rotating body, and the other end is connected with the lock shell. When the door cover is opened, the door cover drives the rotating body to rotate through the lock bolt, and the reset torsional spring is twisted to store energy. After the door cover is opened, the rotating body is rotated to reset the lock bolt under the action of the reset torsional spring. The technical solution realizes the automatic rotation and reset of the lock bolt after the door cover is opened.

[0018] In some embodiments, the side surface of the lock bolt in the axial direction of the rotating body is concavely provided with a limiting sliding groove. The rotating body is provided with a lock bolt stop pin corresponding to the limiting sliding groove. The lock bolt stop pin is inserted into the limiting sliding groove to limit the distance of the lock bolt extending out of the lock shell. The lock bolt and the rotating body are clamped with a lock bolt reset spring, so that the front end of the lock bolt extends out of the lock shell under the action of the lock bolt reset spring. The technical solution realizes the automatic sliding reset of the lock bolt.

[0019] In some embodiments, the front end of the lock tongue has oppositely arranged pressure-retracting surface and pressure-turning surface; the pressure-retracting surface is an inclined arc surface inclined towards the box opening, and the pressure-turning surface is a plane with its normal perpendicular to the sliding direction of the lock tongue; when closing the door cover, the door cover first presses against the pressure-retracting surface to retract the lock tongue into the lock shell, and after the door cover is closed in place, the front end of the lock tongue is reset outside the lock shell and inserted into the lock opening, and the pressure-turning surface presses against the side of the lock opening close to the box opening; when opening the door cover, the door cover is pressed against the pressure-turning surface to drive the lock tongue to rotate. This technical solution further ensures that the door cover drives the lock tongue to slide when closing to smoothly realize the locking of the insulation box, and the door cover drives the lock tongue to rotate when opening to smoothly realize the opening of the insulation box.

[0020] In some embodiments, the stop assembly includes a stop slider and a stop reset spring; the stop slider is slidably connected in the lock shell in the axial direction perpendicular to the rotating body, and the lock shell is provided with a guide groove to guide the sliding of the stop slider; a stop cavity is formed in the stop slider, one end of the guide groove away from the rotating body is provided with a positioning plate, and the positioning plate is inserted into the stop cavity away from the rotating body; the stop reset spring is clamped between the positioning plate and the side wall of the stop cavity close to the rotating body, so that the front end of the stop slider is always pressed against the rotating body under the action of the stop reset spring; the rotating body is provided with a contact portion in the radial direction, the contact portion includes a base section and an enlarged section protruding outward from the base section; the stop slider is pressed against the base section when the lock tongue is not rotating, and the stop slider is pressed against the enlarged section when the lock tongue is rotating, and when the lock tongue is reset, the stop slider is slidably reset under the action of the stop reset spring until it is pressed against the base section. This technical solution matches the stop assembly and the contact portion of the rotating body, which can reliably lock the rotation of the lock tongue when the lock tongue is not rotating, and can ensure the smooth rotation of the lock tongue when the lock tongue is rotating.

[0021] In some embodiments, the actuating assembly includes:

[0022] The action mechanism is electrically connected to the fingerprint recognition mechanism and actuates under its control, and the output shaft of the action mechanism is parallel to the sliding direction of the stop slider; an eccentric shaft is connected to the output shaft of the action mechanism, and the eccentric shaft is parallel to but not coaxial with the output shaft of the action mechanism;

[0023] The limiting push block is arranged parallel to the axial direction of the rotating body, one end of the limiting push block is recessed with a displacement slot, and the limiting push block is covered outside the eccentric shaft through the displacement slot; the other end is provided with a limiting portion, the rear end of the stop slider is pressed against the limiting portion when the action mechanism is not actuated, and the eccentric shaft rotates to drive the limiting push block to slide when the action mechanism is actuated, so that the limiting portion no longer presses against the rear end of the stop slider, so that the stop slider slides away from the rotating body when the lock tongue rotates;

[0024] The limit shaft is arranged parallel to the axial direction of the rotating body, the head of the limit shaft is connected to the lock shell, and the tail is slidably connected to the limit push block; the limit shaft is sleeved with a limit return spring, and the limit return spring is clamped between the head of the limit shaft and the limit push block; when the action mechanism stops actuating, the limit push block is slidably reset under the action of the limit return spring until the limit portion is pressed against the rear end of the stopper sliding block.

[0025] The above technical solution drives the limit push block to slide through the eccentric shaft on the action mechanism, releases the pressing action of the limit push block on the stop assembly, that is, releases the stop of the stop assembly on the rotating body, realizes the unlocking between the door cover and the box body, and then makes the lock tongue rotate to realize the opening of the box under the driving of the door cover; through the setting of the limit return spring, after the door cover is opened and the lock tongue is reset, the limit push block is slidably reset to press the stop assembly again, so as to ensure that the lock tongue does not rotate.

[0026] In some embodiments, an electric appliance chamber is arranged on the box body near the opening end of the door cover, an electric appliance cover is arranged on the electric appliance chamber, the fingerprint identification mechanism is installed on the electric appliance cover, and the lock shell and the lock tongue assembly and the locking mechanism inside the lock shell are installed in the electric appliance chamber.

[0027] In some embodiments, the box opening of the heat preservation box is rectangular, and the opening end of the door cover is located in the short side direction of the box opening.

[0028] In some embodiments, a temperature sensing groove is arranged on the side wall of the accommodating cavity, a temperature sensing probe is arranged in the temperature sensing groove, and a metal protective cover is arranged on the temperature sensing groove to cover the temperature sensing probe in the temperature sensing groove.

[0029] In some embodiments, a ring of bosses is protruded on the door cover, and a ring of grooves matched with the bosses is recessed on the bottom surface of the box body; when a plurality of heat preservation boxes are stacked, the bosses of the lower heat preservation box are inserted into the grooves of the upper heat preservation box.

[0030] Based on the above technical solution, the heat preservation box in the embodiment of the present application realizes the purpose of unlocking the heat preservation box only after fingerprint identification through the setting of the fingerprint lock, so that the heat preservation box has a security function; at the same time, after the heat preservation box is unlocked, the door cover is directly opened to realize the opening of the box, and when the door cover is closed, the fingerprint is not identified, and the door cover is directly released to realize the locking of the box, so that the opening and closing of the heat preservation box is more convenient and fast.

Detailed Implementation

[0047] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0048] In the description of this invention, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," "outer," "left," "right," "front," "rear," "vertical," and "horizontal," etc., indicate the orientation or positional relationship based on the appendix. Figure 1 The orientations or positional relationships shown are for the purpose of facilitating and simplifying the description of the present invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present invention.

[0049] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0050] like Figures 1-13As shown, the heat preservation box of the present application comprises a box body 1, a door cover 2 and a fingerprint lock, which is used to lock or unlock the door cover 2 and the box body 1.

[0051] The box body 1 has a containing cavity 11 and a box opening 12 for the goods to enter or exit the containing cavity 11. The containing cavity 11 is flat inside, and the large arc angle is designed between each side wall and between each side wall and the cavity bottom, which is convenient for the daily cleaning and maintenance of the containing cavity 11. It can be understood that the box body 1 itself is provided with a heat preservation layer to make the heat preservation box have the heat preservation function.

[0052] The door cover 2 is rotationally connected to the box body 1 and is used to open or close the containing cavity 11. Generally, the door cover 2 is covered on the box body 1, and a sealing gasket is arranged between the door cover 2 and the box opening 12 to seal the containing cavity 11. It can be understood that the door cover 2 itself is provided with a heat preservation layer to ensure the heat preservation function of the heat preservation box. Further, one end of the door cover 2 is a connecting end 25, which is rotationally connected to the box body 1 through a hinge 24, so that the door cover 2 is not easy to be removed from the box body 1 without disassembling tools, which can prevent the door cover 2 from being lost. In addition, a long stop portion 16 is arranged on the box body 1 at the connecting position, which is used for the stop positioning after the door cover 2 is opened. The long stop portion 16 can increase the contact area of the door cover 2 and the box body 1, reduce the local stress, reduce the damage risk of the door cover 2 when it is occasionally violently opened, increase the service life of the heat preservation box, and make it more durable. The other end of the door cover 2 is an opening end 26, and a handle 23 is recessed at the opening end 26, which is convenient for the user to open the door cover 2.

[0053] The fingerprint lock comprises a lock shell 3, a lock tongue assembly 4, a locking mechanism and a fingerprint identification mechanism 7. The lock shell 3 is installed at the box opening 12 of the box body 1 and close to the opening end 26 of the door cover 2. The lock tongue assembly 4 comprises a rotating body 41 and a lock tongue 42. The rotating body 41 is rotationally connected in the lock shell 3, that is, the rotating body 41 can rotate relative to the lock shell 3, and the rotation axis direction is parallel to the opening end 26 of the door cover 2. The lock tongue 42 is slidingly connected in the rotating body 41 along the direction perpendicular to the axial direction of the rotating body 41, that is, the lock tongue 42 can reciprocate relative to the rotating body 41 along the direction perpendicular to the axial direction of the rotating body 41, so that the front end of the lock tongue 42 can extend out of the lock shell 3 or retreat into the lock shell 3. Specifically, a sliding cavity 411 is formed in the rotating body 41 along the direction perpendicular to the axial direction of the rotating body 41, the opening of the sliding cavity 411 faces the opening end 26 of the door cover 2, a sliding hole 412 is formed in the middle of the cavity bottom of the sliding cavity 411, a guide shaft 424 of the lock tongue 42 is protruded and inserted into the sliding hole 412, and the guide shaft 424 of the lock tongue 42 is always located in the sliding hole 412 of the rotating body 41 during the movement of the lock tongue 42. The opening end 26 of the door cover 2 is recessed with a lock opening 21 matched with the lock tongue 42, so that the front end of the lock tongue 42 can be inserted into the lock opening 21 after extending out of the lock shell 3.

[0054] Further, when the door cover 2 is in the locked state with the box body 1, the lock tongue 42 is inserted into the lock opening 21 of the door cover 2. When the door cover 2 is opened, the door cover 2 drives the lock tongue 42 to rotate so that the lock tongue 42 is separated from the lock opening 21. It should be noted that at this time, the door cover 2 presses the lock tongue 42, the lock tongue 42 drives the rotating body 41, and the two rotate together. After the door cover 2 is opened, the lock tongue 42 is rotated and reset under the drive of the rotating body 41. When the door cover 2 is closed, the door cover 2 presses the lock tongue 42 to retreat into the lock shell 3. It should be noted that at this time, the rotating body 41 is not moved, the lock tongue 42 slides towards the rotating body 41, and is slid into the lock shell 3. After the door cover 2 is closed in place, the lock tongue 42 slides towards the outside of the rotating body 41, and the front end of the lock tongue 42 extends out of the lock shell 3 to reset and is inserted into the lock opening 21.

[0055] The locking mechanism includes a stop assembly 5 and an actuating assembly 6. One end of the stop assembly 5 abuts against the rotating body 41. When the actuating assembly 6 is not actuated, the actuating assembly 6 abuts against the stop assembly 5 to stop the rotating body 41, so that the lock tongue 42 does not rotate. When the actuating assembly 6 is actuated, the actuating assembly 6 no longer abuts against the stop assembly 5 to release the stop of the rotating body 41, so that the lock tongue 42 and the rotating body 41 can rotate under the drive of the door cover 2.

[0056] The fingerprint identification mechanism 7 has a fingerprint collection plate for identifying the fingerprint information of a user. The fingerprint identification mechanism 7 is electrically connected with the actuating assembly 6 to control the actuation of the actuating assembly 6. That is, the fingerprint identification mechanism 7 can only instruct the actuating assembly 6 to actuate after identifying the correct fingerprint information, so as to unlock the door cover 2 from the box body 1.

[0057] The above-mentioned exemplary embodiment realizes the technical effect that the fingerprint identification mechanism 7 and the locking mechanism are provided to enable the fingerprint identification before the thermal insulation box is unlocked, so that the thermal insulation box has a security function. Through the provision of the lock tongue assembly 4, after the thermal insulation box is unlocked by the fingerprint, the door cover 2 is directly opened to drive the lock tongue 42 to rotate to open the box, and when the door cover 2 is closed, the fingerprint does not need to be identified, and the door cover 2 is directly released to drive the lock tongue 42 to slide to lock the box, so that the opening and closing of the thermal insulation box are more convenient and fast.

[0058] As Figure 4 , Figures 8-10As shown in the figure, in some embodiments, the lock tongue assembly 4 further comprises a reset torsion spring 43, one end of which is connected with the rotating body 41 and the other end of which is connected with the lock shell 3. When the door cover 2 is opened, the door cover 2 drives the rotating body 41 to rotate through the lock tongue 42, and the reset torsion spring 43 is twisted to store energy; specifically, the connecting end of the reset torsion spring 43 with the rotating body 41 moves with the rotating body 41, and the connecting end of the reset torsion spring 43 with the lock shell 3 stores the reset rotation force. After the door cover 2 is opened, the reset torsion spring 43 releases the stored rotation force, and the rotating body 41 rotates back under the action of the reset torsion spring 43, driving the lock tongue 42 to reset. This illustrative embodiment realizes the automatic rotation reset of the lock tongue 42 after the door cover 2 is opened.

[0059] As shown in the figure, Figure 8 , Figure 9 In some embodiments, the lock tongue 42 is recessed with a limiting sliding groove 423 on the side surface in the axial direction of the rotating body 41, and the rotating body 41 is internally provided with a lock tongue limiting pin 44 corresponding to the limiting sliding groove 423; the lock tongue limiting pin 44 is inserted into the limiting sliding groove 423 to limit the distance of the front end of the lock tongue 42 extending out of the lock shell 3. The lock tongue 42 and the rotating body 41 are clamped with a lock tongue reset spring 45 therebetween, specifically, the lock tongue reset spring 45 is clamped between the rear end of the lock tongue 42 and the cavity bottom of the sliding cavity 411 of the rotating body 41, so that the front end of the lock tongue 42 can extend out of the lock shell 3 under the action of the lock tongue reset spring 45. In addition, it should be noted that although the figure of the present embodiment only configures the lock tongue limiting pin 44 on one side of the lock tongue 42, the present application is not limited thereto, and those skilled in the art can configure the lock tongue limiting pin 44 on both sides of the lock tongue 42 according to actual needs to limit the distance of the lock tongue 42 extending out of the lock shell 3. This illustrative embodiment realizes the automatic sliding reset of the lock tongue 42.

[0060] As shown in the figure, Figure 5 , Figure 11As shown, in some embodiments, the front end of the locking tongue 42 has a relatively arranged pressure-retracting surface 421 and a pressure-turning surface 422. The pressure-retracting surface 421 is an inclined arc surface inclined towards the box opening 12; the pressure-turning surface 422 is a plane, the normal of which is perpendicular to the sliding direction of the locking tongue 42. When closing the door cover 2, the door cover 2 first presses against the pressure-retracting surface 421. Since the pressure-retracting surface 421 is an inclined arc surface, part of the downward pressure of the door cover 2 on the pressure-retracting surface 421 is converted into the sliding force of the locking tongue 42 sliding into the rotating body 41, so that the locking tongue 42 is retracted into the lock shell 3 along the sliding cavity 411 of the rotating body 41. After the door cover 2 is closed in place, the front end of the locking tongue 42 is reset to extend out of the lock shell 3 under the action of the locking tongue reset spring 45 and is inserted into the lock opening 21, and the pressure-turning surface 422 of the locking tongue 42 is pressed against the side of the lock opening 21 close to the box opening 12, so that the door cover 2 and the box body 1 are locked. When opening the door cover 2, the door cover 2 presses on the pressure-turning surface 422. Since the normal of the pressure-turning surface 422 is perpendicular to the sliding direction of the locking tongue 42, the pressure of the door cover 2 on the pressure-turning surface 422 will not make the locking tongue 42 slide, but will make the locking tongue 42 rotate. Since the locking tongue 42 is connected in the rotating body 41, the locking tongue 42 will make the rotating body 41 rotate together until the door cover 2 is opened completely. This illustrative embodiment further ensures that the door cover 2 can make the locking tongue 42 slide to smoothly achieve the locking of the heat preservation box when closing, and ensures that the door cover 2 can make the locking tongue 42 rotate to smoothly achieve the opening of the heat preservation box when opening.

[0061] As shown in FIG. 1, Figure 4 , Figure 6 , Figures 9-12 As shown, in some embodiments, the stop assembly 5 includes a stop sliding block 51 and a stop reset spring 52. The stop sliding block 51 is slidingly connected in the lock shell 3 in the axial direction perpendicular to the rotating body 41, and the lock shell 3 is provided with a guide groove 31 to guide the sliding of the stop sliding block 51. The stop sliding block 51 is provided with a stop cavity 511, and the end of the guide groove 31 away from the rotating body 41 is provided with a positioning plate 32 inserted into the side of the stop cavity 511 away from the rotating body 41. The stop reset spring 52 is clamped between the positioning plate 32 and the side wall of the stop cavity 511 close to the rotating body 41, so that the front end of the stop sliding block 51 is always pressed against the rotating body 41 under the action of the stop reset spring 52.

[0062] The rotating body 41 is provided with a contact portion 413 in the radial direction, which includes a base section 4131 and an enlarged section 4132 protruding outward from the base section 4131, i.e. the base section 4131 and the enlarged section 4132 are provided in different diameters. For example, the contact portion 413 can be provided in a cam shape. When the lock tongue 42 is not rotated, the front end of the stop slide block 51 is pressed against the base section 4131. When the lock tongue 42 is rotated, the rotating body 41 is also rotated, and the contact position of the stop slide block 51 with the rotating body 41 is changed from the base section 4131 to the enlarged section 4132. Thus, the rotating force of the rotating body 41 can be converted into a sliding force applied to the stop slide block 51, so that the stop slide block 51 slides away from the rotating body 41 until the front end of the stop slide block 51 is pressed against the enlarged section 4132. During this process, the stop reset spring 52 is compressed. When the lock tongue 42 and the rotating body 41 are rotated back, the contact position of the stop slide block 51 with the rotating body 41 is changed from the enlarged section 4132 to the base section 4131, and the stop slide block 51 is slid back under the action of the stop reset spring 52 until the front end of the stop slide block 51 is pressed against the base section 4131.

[0063] According to the above-mentioned exemplary embodiments, the matching arrangement between the stop assembly 5 and the contact portion 413 of the rotating body 41 can reliably lock the stop state of the lock tongue 42 when the lock tongue 42 is not rotated, and can ensure the smooth rotation of the lock tongue 42 when the lock tongue 42 is rotated.

[0064] As shown in Figure 4 、 Figure 6 、 Figure 7 、 Figure 9 、 Figure 10 、 Figure 13 In some embodiments, the actuating assembly 6 includes an actuating mechanism 61, a limiting push block 62 and a limiting shaft 63.

[0065] The actuating mechanism 61 is electrically connected to the fingerprint recognition mechanism 7 and is actuated under the control of the fingerprint recognition mechanism 7. The output shaft of the actuating mechanism 61 is parallel to the sliding direction of the stop slide block 51. An eccentric shaft 611 is connected to the output shaft of the actuating mechanism 61, and the eccentric shaft 611 is parallel to but not coaxial with the output shaft of the actuating mechanism 61. When the actuating mechanism 61 is actuated, the output shaft is rotated, and the eccentric shaft 611 is further rotated around the output shaft.

[0066] The limiting push block 62 is arranged parallel to the axial direction of the rotating body 41, and one end of the limiting push block 62 is recessed with a displacement slot 621 in an arch shape, and the limiting push block 62 is covered outside the eccentric shaft 611 through the displacement slot 621; the other end of the limiting push block 62 is protruded with a limiting portion 622. When the action mechanism 61 is not actuated, the limiting portion 622 of the limiting push block 62 abuts against the rear end of the stop slide block 51, and when the action mechanism 61 is actuated, the eccentric shaft 611 rotates to drive the limiting push block 62 to slide along the axial direction parallel to the rotating body 41, that is, the rotation of the eccentric shaft 611 is converted into the sliding of the limiting push block 62, so that the limiting portion 622 of the limiting push block 62 no longer abuts against the rear end of the stop slide block 51, and further, the stop slide block 51 can slide away from the rotating body 41 under the action of the abutting portion 413 of the rotating body 41 when the locking tongue 42 rotates.

[0067] The limiting shaft 63 is arranged parallel to the axial direction of the rotating body 41, and the head of the limiting shaft 63 is connected in the lock shell 3, and the tail is slidingly connected with the limiting push block 62. The limiting shaft 63 is sleeved with a limiting return spring 64, and the limiting return spring 64 is clamped between the head of the limiting shaft 63 and the limiting push block 62. After the action mechanism 61 stops actuating and the door cover 2 is opened, the rotating body 41 and the locking tongue 42 are rotated and reset under the action of the reset torsion spring 43, the stop slide block 51 is slidingly reset under the action of the stop reset spring, and the limiting push block 62 is slidingly reset under the action of the limiting reset spring 64, until the limiting portion 622 abuts against the rear end of the stop slide block 51.

[0068] In the above-mentioned schematic embodiment, the eccentric shaft 611 on the action mechanism 61 drives the limiting push block 62 to slide, and the abutting action of the limiting push block 62 on the stop assembly 5 is released, that is, the stop of the stop assembly 5 on the rotating body 41 is released, the unlocking between the door cover 2 and the cabinet 1 is realized, and further, the locking tongue 42 can be rotated to open the cabinet under the driving of the door cover 2; through the setting of the limiting reset spring 64, after the door cover 2 is opened and the locking tongue 42 is rotated and reset, the limiting push block 62 is slidingly reset to abut against the stop assembly 5 again, so as to ensure that the locking tongue 42 does not rotate.

[0069] As shown in Figure 1 , Figure 3 , Figure 5 , Figure 6 , Figure 11 , Figure 12 In some embodiments, the cabinet 1 is provided with an electrical chamber 13 near the opening end 26 of the door cover 2, the electrical chamber 13 is covered with an electrical cover 14, the fingerprint identification mechanism 7 is installed on the electrical cover 14, and the lock shell 3 and the locking tongue assembly 4, the locking mechanism and the like inside the lock shell 3 are installed in the electrical chamber 13, so that the heat preservation box has an independent electrical space, and it is more convenient to replace the battery and overhaul the electrical components.

[0070] As shown in Figure 1, Figure 3 As shown, in some embodiments, the opening 12 of the insulated box is rectangular, and the opening end 26 of the door cover 2 is located in the short side direction of the opening 12, that is, the electrical compartment 13 is arranged in the short side direction of the opening 12. Therefore, compared with setting the opening end 26 of the door cover 2 in the long side direction of the opening 12, under the same external dimensions of the insulated box, this embodiment significantly reduces the occupation of the electrical compartment 13 on the housing cavity 11 of the box body 1, and realizes the volume optimization of the housing cavity 11 of the insulated box.

[0071] like Figure 2 As shown, in some embodiments, the two side walls of the insulated box 1 along the length direction are recessed with handles 17, and the handles 17 are provided with anti-slip ribs to facilitate manual handling of the insulated box; at the same time, the purpose of placing the handles 17 along the length direction of the box body 1 is also to reduce the occupancy of the handles 17 on the box body 1 receiving cavity 11, and further optimize the volume of the receiving cavity 11 of the insulated box.

[0072] like Figure 3 As shown, in some embodiments, a temperature sensing groove 111 is provided on the side wall of the accommodating cavity 11, and a temperature sensing probe 112 is installed inside the temperature sensing groove 111. A metal protective cover 113 is installed on the temperature sensing groove 111 to cover the temperature sensing probe 112 inside the temperature sensing groove 111, so as to prevent the temperature sensing probe 112 from being contaminated or damaged by soup, medicine or other items stored in the insulated box. At the same time, because metal itself has good thermal conductivity, the metal protective cover 113 protects the temperature sensing probe 112 without affecting the temperature sensing probe 112's sensing of the temperature inside the box. In addition, the temperature sensing groove 111 can be provided on the side wall of the accommodating cavity 11 near the electrical compartment 13, so that the cable of the temperature sensing probe 112 can be connected to the temperature display 114 on the electrical cover 14 at close range. The temperature display 114 is used to visually display the temperature inside the box.

[0073] like Figure 1 , Figure 2 As shown, in some embodiments, a raised boss 22 is provided on the door cover 2, and a recessed groove 15 that matches the boss 22 is provided on the bottom surface of the box body 1. When multiple insulated boxes are stacked one on top of the other, the boss 22 of the lower insulated box is inserted into the groove 15 of the upper insulated box, making it easier for multiple insulated boxes to be stacked on top of each other and less likely to collapse, thus facilitating the stacking and storage of insulated boxes.

[0074] like Figure 1 , Figure 2 As shown, in some embodiments, several sets of protective ribs 18 are arranged on two opposite side walls near the bottom of the box 1 to avoid scratch damage to the bottom side of the box 1 when the insulated box is transferred on the production line, so as to ensure the insulation effect of the insulated box.

[0075] Through the description of the multiple embodiments of the heat preservation box, it can be seen that the heat preservation box has at least one or more of the following advantages:

[0076] 1. By setting the fingerprint lock, the purpose of unlocking the heat preservation box after fingerprint identification is realized, so that the heat preservation box has a security function; at the same time, after unlocking the heat preservation box, the door cover is directly opened to drive the lock tongue to rotate and realize the opening of the box, and when closing the door cover, the fingerprint is not identified, and the door cover is directly released to drive the lock tongue to slide and realize the locking of the box, so that the opening and closing of the heat preservation box is more convenient and fast;

[0077] 2. By placing the temperature sensing probe in the temperature sensing groove on the side wall of the accommodating cavity and installing the metal protective cover, the protection of the temperature sensing probe is realized, the temperature sensing probe is prevented from being polluted or damaged, and the temperature sensing of the temperature sensing probe in the box is not affected;

[0078] 3. By matching the boss on the door cover and the groove on the bottom of the box body, the problem of easy collapse of multiple heat preservation boxes when stacked is solved, and the stacking and storage of the heat preservation boxes are more convenient.

[0079] Finally, it should be explained that: in the specification, each embodiment is described in a progressive manner, and each embodiment focuses on the difference from other embodiments. The same and similar parts of each embodiment can be referred to.
