DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0038] It should be noted that, unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0039] At present, the application of thermal insulation boxes has appeared in the catering industry. In the industry, the prepared cooked food is placed in the thermal insulation box to keep the food warm. In order to enable the cooked food to be placed in the thermal insulation box by category, the thermal insulation boxes on the market are equipped with a certain number of thermal insulation trays for placing different ingredients. In order to facilitate the quick identification and taking of the corresponding cooked food, the handles of these thermal insulation trays are generally clamped with clips of different colors for distinction.

[0040] However, these clips are not very stable when set on the handles of the insulation plate. In application scenarios such as cleaning, recycling and stacking, these clips are easy to slip due to external forces other than gravity, making them inconvenient to use.

[0041] Based on this, an embodiment of the present application provides a heat preservation plate, a plate clamp, and a heat preservation box, aiming to improve the stability of the plate clamp's groove-type handle.

[0042] The heat preservation tray, tray clamp and heat preservation box provided in the embodiment of the present application are specifically described through the following embodiments. First, the tray clamp provided in the embodiment of the present application is described.

[0043] See also Figures 1 to 4 , Figure 1 A schematic diagram of the structure of a first angle of a disk clamp provided by an embodiment of the present application, Figure 2 for Figure 1 A schematic structural diagram of a second angle of the disc clamp; Figure 3 is a schematic structural diagram of a disk clamp at a first angle provided by another embodiment of the present application; Figure 4 yes Figure 2In the embodiment of the present application, the heat preservation plate 2 includes but is not limited to the grooved handle 21; the plate clamp 1 includes but is not limited to the first clamping plate portion 11, the second clamping plate portion 12 and the internal resistance portion 13.

[0044] The first clamping plate portion 11 and the second clamping plate portion 12 are connected to form a clamping structure for clamping the grooved handle 21. The internal resistance portion 13 is disposed on the first clamping plate portion 11 and located between the first clamping plate portion 11 and the second clamping plate portion 12 to form a clamping space 14 with the second clamping plate portion 12.

[0045] It should be noted that the specific form of the second clamping plate portion 12 is diverse, and may be the following embodiments or other embodiments, and the embodiments of the present application are not limited to this.

[0046] It should be noted that, in order to facilitate the explanation of the working principle of the disk clamp 1, the embodiments of each disk clamp 1 in the present application adopt a cleaning scenario as the scenario in which the disk clamp 1 is subjected to external force. Other scenarios in which external force is applied to the disk clamp 1 can refer to the working principle of the disk clamp 1 in the cleaning scenario, and this application will not go into details.

[0047] See also Figure 5 , Figure 5 A schematic diagram of a clamping device for a disk clamp according to an embodiment of the present application. In one embodiment, under the premise that both the first clamping plate portion 11 and the second clamping plate portion 12 are in contact with the grooved handle 21, the second clamping plate portion 12 is a straight plate, and forms an "A"-shaped structure with the first clamping plate portion 11 and the internal resistance portion 13.

[0048] When the disk clamp 1 clamps the grooved handle 21, the disk clamp 1 is stretched open by the grooved handle 21 and obtains elastic potential energy, which will prompt the disk clamp 1 to return to its original state, so that the first clamping plate portion 11 and the second clamping plate portion 12 have a tendency to contract toward each other. This mutual contraction tendency causes the first clamping plate portion 11 to apply pressure to and touch the surface of the groove 22 of the grooved handle 21, and the second clamping plate portion 12 to apply pressure to and touch the outer wall of the groove 22; one end of the groove 22 of the grooved handle 21 penetrates into the clamping space 14, and under the action of the first clamping plate portion 11, the internal resistance portion 13 applies pressure to and touches the surface of the groove 22. Under the action of gravity alone, the disk clamp 1 generates a clockwise rotation tendency to slide down. At this time, the clockwise rotation tendency causes the top contact point between the first clamping plate portion 11 and the surface of the groove 22, the top contact point between the second clamping plate portion 12 and the outer wall of the groove 22, and the inner resistance portion 13 and the surface of the groove 22 to generate a counterclockwise friction force to offset the clockwise rotation tendency of the disk clamp 1. In addition, the clockwise rotation tendency will be converted into a tendency to stretch the disk clamp 1 on the disk clamp 1, so that the tendency of the first clamping plate portion 11 and the second clamping plate portion 12 to contract toward each other is enhanced. At this time, the pressure applied by the first clamping plate portion 11 to the surface of the groove 22 of the groove handle 21 and the pressure applied by the second clamping plate portion 12 to the outer wall of the groove 22 will be increased, and the pressure applied by the inner resistance portion 13 to the surface of the groove 22 will also be increased, thereby increasing the friction between the first clamping plate portion 11, the second clamping plate portion 12 and the inner resistance portion 13 and the groove 22 respectively.

[0049] When cleaning the heat preservation plate 2, the following two situations may occur but are not limited to: the water flow impacts the plate clamp 1 upwards and the water flow impacts the plate clamp 1 downwards. In the case where the water flow impacts the plate clamp 1 downwards, the force exerted by the water flow impact on the plate clamp 1 is superimposed on the gravity to form a composite force. At this time, the composite force acts on the plate clamp 1 in the same way as gravity, but because the value of the composite force is greater than gravity, the pressure exerted by the first clamping plate portion 11, the second clamping plate portion 12 and the internal resistance portion 13 on the groove 22 will be further increased, thereby increasing the friction between the first clamping plate portion 11, the second clamping plate portion 12 and the internal resistance portion 13 and the groove 22 respectively; in the case where the water flow impacts the plate clamp 1 upwards, the water flow impact exerts an upward force on the plate clamp 1, causing the plate clamp 1 to produce The counterclockwise rotation tendency is generated, and the counterclockwise rotation tendency makes the disk clamp 1 have a tendency to shrink and disengage outward, so that the pressure applied by the second clamp part 12 and the first clamp part 11 on the groove 22 is reduced, and the friction between the first clamp part 11 and the second clamp part 12 and the groove 22 is reduced. The disengagement tendency of the first clamp part 11 increases the degree to which the internal resistance part 13 presses down the surface of the groove 22, and increases the friction between the internal resistance part 13 and the surface of the groove 22, so that the counterclockwise rotation tendency of the disk clamp 1 can be offset, thereby improving the stability of the disk clamp 1 clamping the groove-type handle 21.

[0050] See also Figure 1 and Figure 3 In one embodiment, the second clamping plate portion 12 is bent toward the first clamping plate portion 11 to form an inner bending structure 121 , and the inner bending structure 121 surrounds the inner resistance portion 13 .

[0051] It should be noted that the disk clamp 1 here has various ways of clamping the grooved handle 21, which can be the following embodiments or other embodiments, and the embodiments of the present application are not limited to this.

[0052] See also Figure 6 and Figure 7 , Figure 6 for Figure 1 A schematic diagram of a clamping embodiment of the disk clamp in FIG. Figure 7 for Figure 2Schematic diagram of a clamping embodiment of the disk clamp in FIG. When the disk clamp 1 clamps the grooved handle 21, the first clamping plate portion 11 contacts the surface of the groove 22 of the grooved handle 21; the inner curved structure 121 covers the outer wall of the groove 22 and contacts the outer wall; one end of the groove 22 penetrates into the clamping space 14, and the inner resistance portion 13 contacts the surface of the groove 22. Under the action of gravity alone, the disk clamp 1 has a clockwise rotation tendency. At this time, the top contact point formed by the first clamping plate portion 11 and the surface of the groove 22 will form a counterclockwise friction force, the top contact point formed by the inner curved structure 121 and the outer wall of the groove 22 will form a counterclockwise friction force, and the top contact point formed by the inner resistance portion 13 and the surface of the groove 22 will form a counterclockwise friction force. The clockwise rotation trend is converted into a tendency to stretch the disk clamp 1 on the disk clamp 1, so that the tendency of the first clamp portion 11 and the second clamp portion 12 to contract toward each other is enhanced, thereby increasing the friction between the first clamp portion 11, the second clamp portion 12 and the internal resistance portion 13 and the groove 22 respectively.

[0053] When cleaning the insulation plate 2, in the case where water flows downwardly to impact the plate clamp 1, the force generated by the water flow impacting the plate clamp 1 is superimposed on gravity to form a composite force. At this time, the composite force acts on the plate clamp 1 in the same way as gravity, thereby increasing the friction between the first clamping plate portion 11, the second clamping plate portion 12 and the internal resistance portion 13 and the groove 22 respectively; in the case where water flows upward to impact the plate clamp 1, the plate clamp 1 will have a counterclockwise rotation tendency. At this time, the shape of the inward bending structure 121 matches the outer wall of the groove 22, and the outward separation tendency of the plate clamp 1 will be converted into a rigid deformation tendency of the inward bending structure 121, which increases the friction between the inward bending structure 121 and the outer wall of the groove 22, thereby increasing the friction between the internal resistance portion 13 and the surface of the groove 22 and the friction between the first clamping plate portion 11 and the surface of the groove 22, thereby improving the stability of the plate clamp 1 holding the groove-type handle 21.

[0054] It should be noted that the size of the inner curved structure 121 is various, for example, Figure 6 and Figure 7 In the illustrated embodiment, the inwardly curved structure 121 matches the size of the groove 22, and the groove 22 is entirely covered; for another example, the inwardly curved structure 121 partially matches the size of the groove 22, and the groove 22 is partially covered, etc., and this embodiment of the present application is not limited to this.

[0055] See also Figure 8 , Figure 8 for Figure 1Schematic diagram of another clamping embodiment of the disk clamp in FIG. When the clamping structure clamps the grooved handle 21, the grooved handle 21 opens the disk clamp 1, and the disk clamp 1 obtains elastic potential energy, which causes the first clamping plate portion 11 and the second clamping plate portion 12 to contract toward each other, the first clamping plate portion 11 contacts the outer wall of the groove 22, the second clamping plate portion 12 contacts the inner surface of the groove 22, and the internal resistance portion 13 is hooked back on the grooved handle 21. Under the action of gravity alone, the disk clamp 1 will have a clockwise flipping trend, the top contact point formed by the first clamping plate portion 11 and the surface of the groove 22 will form a counterclockwise friction force, the top contact point formed by the second clamping plate portion 12 and the outer wall of the groove 22 will form a counterclockwise friction force, and the internal resistance portion 13 exerts pressure on the reverse hook position of the grooved handle 21 due to the pressure generated by the first clamping plate portion 11 and the second clamping plate portion 12 on the grooved handle 21, thereby forming a counterclockwise friction force.

[0056] When cleaning the insulation plate 2, when the water flows downwardly against the plate clamp 1, the downward force generated by the water flow is superimposed on the gravity. This is the same as the case where only gravity acts, but the three counterclockwise friction forces will be relatively increased; when the water flows upward against the plate clamp 1, the plate clamp 1 will have a counterclockwise rotation tendency. Since the internal resistance portion 13 is hooked onto the grooved handle 21, the counterclockwise rotation tendency increases the pressure applied by the internal resistance portion 13 on the grooved handle 21, and the pressure applied by the second clamping plate portion 12 on the surface of the groove 22, thereby increasing the friction between the grooved handle 21 and the internal resistance portion 13, and between the second clamping plate portions 12, thereby improving the stability of the plate clamp 1 clamping the grooved handle 21.

[0057] It should be noted that the first clamping plate portion 11 and the second clamping plate portion 12 may be connected in various ways, for example, Figure 1 and Figure 3 In the connection mode shown, the first clamping plate portion 11 and the second clamping plate portion 12 are integrally connected, and the grooved handle 21 is clamped by the elastic potential energy generated by the deformation of the first clamping plate portion 11 and the second clamping plate portion 12; for another example, the first clamping plate portion 11 and the second clamping plate portion 12 are connected by a torsion spring, and the grooved handle 21 is clamped by the elastic potential energy provided by the torsion spring, etc., and the embodiments of the present application are not limited to this.

[0058] The embodiment of the present application provides an internal resistance portion so that when the disk clamp is subjected to external force, the internal resistance portion exerts pressure on the grooved handle by utilizing the detachment tendency of the disk clamp to enhance the pressure, thereby increasing the relative friction between the disk clamp and the grooved handle, thereby increasing the stability of the disk clamp clamping the grooved handle.

[0059] See also Fig. 9 , Fig. 9 for Figure 1In one embodiment, the second clamping plate portion 12 includes but is not limited to a hook-shaped structure 122. The hook-shaped structure 122 is disposed on the second clamping plate portion 12 and is located at a side away from the connection between the first clamping plate portion 11 and the second clamping plate portion 12.

[0060] Specifically, see Figure 7 and Fig. 9 Since the second clamping plate portion 12 is provided with a hook-shaped structure 122, the hook-shaped structure 122 will contact the outer wall of the groove 22, so that the side of the second clamping plate portion 12 provided with the hook-shaped structure 122 will be relatively lifted to a certain height. When one side of the second clamping plate portion 12 is lifted to a certain height, the second clamping plate portion 12 itself will undergo rigid deformation, so that the second clamping plate portion 12 has a certain elastic potential energy, and this elastic potential energy will act on the hook-shaped structure 122, so that the hook-shaped structure 122 and the outer wall of the groove 22 are more closely contacted, thereby increasing the friction between the second clamping plate portion 12 and the groove 22, and increasing the stability of the disk clamp 1 in clamping the groove-shaped handle 21.

[0061] The embodiment of the present application provides a hook-shaped portion on the second clamping plate portion to utilize the elastic potential energy generated by the rigid deformation of the second clamping plate portion to increase the friction between the second clamping plate portion and the outer wall of the groove, so that the disk clamp can be more firmly arranged on the groove-shaped handle.

[0062] It should be noted that the internal resistance portion 13 may be disposed at various positions. Figure 1 The configuration shown may also be the following embodiments or other embodiments, and the embodiments of the present application are not limited to this.

[0063] See also Figure 1 In one embodiment, the internal resistance portion 13 is disposed on the inner surface of the first clamping plate portion 11 and is located on a side where the first clamping plate portion 11 is connected to the second clamping plate portion 12 .

[0064] See also Figure 3 In one embodiment, the internal resistance portion 13 is disposed at one end of the first clamping plate portion 11 and is away from the connection between the first clamping plate portion 11 and the second clamping plate portion 12; the first clamping plate portion 11 includes but is not limited to the first extension portion 111. The first extension portion 111 is disposed at the connection between the internal resistance portion 13 and the first clamping plate portion 11 and extends to the outer surface away from the first clamping plate portion 11.

[0065] Specifically, when the disk clamp 1 is set on the groove handle 21, the groove 22 is clamped by the clamping space, and the first clamping plate portion 11 also fits and contacts the surface of the groove 22. At this time, since the first clamping plate portion 11 fits and contacts the surface of the groove 22, the first extension portion 111 can fit and contact the surface of the groove 22, thereby increasing the friction between the first clamping plate portion 11 as a whole and the surface of the groove 22.

[0066] The embodiment of the present application increases the contact area between the first clamping plate portion and the groove surface by providing a first extension portion, so that the friction between the first clamping plate portion as a whole and the surface of the top-contact groove 22 is improved, thereby improving the stability of the disk clamp provided on the groove-type handle.

[0067] It should be noted that the shape of the internal resistance portion 13 here is diverse and can be the following embodiments or other embodiments, and the embodiments of the present application are not limited to this.

[0068] In one embodiment, if Figure 6 and Figure 7 As shown, the internal resistance portion 13 is bent toward the connection between the first clamping plate portion 11 and the second clamping plate portion 12 to form an inner hook structure, which is used to contact the surface of the groove 22 when located in the groove 22 of the groove handle 21.

[0069] In one embodiment, the internal resistance portion 13 is a boss structure, which is protruded from the inner surface of the first clamping plate portion 11 . The upper surface of the boss structure is curved and matches the surface of the groove 22 , so that the surface of the groove 22 is touched when the clamping structure clamps the groove-type handle 21 .

[0070] In one embodiment, the second clamping plate portion 12 further includes but is not limited to an inner convex structure 123 . The inner convex structure 123 is disposed on the inner surface of the second clamping plate portion and is located on a side of the second clamping plate portion 12 connected to the first clamping plate portion 11 .

[0071] For example, Figure 7 As shown, when the disk clamp 1 clamps the groove-shaped handle 21, the inner convex structure 123 will contact the outer wall of the groove 22, so that the second clamping plate portion 12 is partially lifted to a certain height by the inner convex structure 123. When the second clamping plate portion 12 is partially lifted to a certain height by the inner convex structure 123, the second clamping plate portion 12 itself will produce rigid deformation, so that the second clamping plate portion 12 obtains a certain elastic potential energy, and the elastic potential energy causes the second clamping plate portion 12 to restore its original state, thereby acting on the inner convex structure 123 to press the outer wall of the groove 22, so that the inner convex structure 123 and the outer wall of the groove 22 are more closely contacted, thereby improving the friction between the second clamping plate portion 12 and the groove 22, and improving the stability of the disk clamp 1 clamping the groove-shaped handle 21.

[0072] See also Figure 4 and Fig.10 , Fig.10 A schematic diagram of the structure of a disk clamp provided in another embodiment of the present application. In one embodiment, the disk clamp 1 further includes but is not limited to a second extension portion 15. The second extension portion 15 is disposed at the connection between the first clamp portion 11 and the second clamp portion 12, and extends in a direction away from the first clamp portion 11 and the second clamp portion 12.

[0073] Specifically, a second extension portion 15 is provided at the connection between the first clamping plate portion 11 and the second clamping plate portion 12, and the second extension portion 15 extends in a direction away from the first clamping plate portion 11 and the second clamping plate portion 12. When the disk clamp 1 needs to be removed from the grooved handle 21, the second extension portion 15 can provide a force point for pushing the disk clamp 1 upward, so that the disk clamp 1 can be more easily removed from the grooved handle 21.

[0074] See also Figure 6 In one embodiment, the second clamping plate portion 12 further includes but is not limited to a convex structure 124. The convex structure 124 is disposed on the outer surface of the inner curved structure 121 and is located on a side away from the connection between the first clamping plate portion 11 and the second clamping plate portion 12. The convex structure 124 is used to contact the surface of the groove 22 when the second clamping plate portion 12 is located in the groove 22 of the grooved handle 21.

[0075] Specifically, the convex structure 124 increases the thickness of one side of the second clamping plate portion 12 away from the connection between the first clamping plate portion 11 and the second clamping plate portion 12, thereby improving the strength of the second clamping plate portion 12 on this side, so that the second clamping plate portion 12 on this side can obtain more elastic potential energy under the same degree of rigid deformation, thereby improving the friction between the side and the outer wall of the groove 22; and Figure 8 In the usage mode shown, the contraction tendency of the second clamping plate portion 12 is enhanced by the convex structure 124 , so that the friction between the convex structure 124 and the surface of the groove 22 can be improved.
