[0002] Cookers are commonly used kitchen cooking appliances in daily family life. With the improvement of people's quality of life, users generally choose embedded cookers in modern decoration. The reason is that the cooktop glass of embedded cookers can be close to the same plane as the countertop, so it has the advantages of saving cooktop space, improving the overall appearance of the kitchen and facilitating cleaning.

[0003] In order to reduce costs, the embedded frames of some built-in stoves are spliced ​​and fixed by multiple frame strips. Since the frame strips are mostly fixed by bolts, there is mechanical stress after the bolts are tightened, which will cause gaps or steps in the connection positions of two adjacent frame strips after assembly, causing the splicing positions of the embedded frame to be loose and affecting the aesthetics of the embedded frame. Summary of the invention

[0010] In some embodiments, the stove top structure further includes a sealing ring surrounding the stove top glass, wherein the sealing ring is located between the bracket and the stove top glass and is tightly attached to both in a horizontal direction.

[0011] In some embodiments, each of the splicing sections comprises a flange, the bracket and the connecting portion fixed in sequence;

[0012] The stove top structure is installed on the table top, the flange bottom surface is in contact with the upper surface of the table top to support the embedded bracket, and the bracket is located in the stove groove of the table top.

[0013] In some embodiments, a matching portion is fixed on the inner side of the bracket, the upper surface of the matching portion is flush with the flange, and the inner side surface of the matching portion is inclined outward from top to bottom, and the edge of the upper surface of the stove top glass along the circumferential direction has a chamfer that corresponds to the inner side surface of the matching portion.

[0014] In some embodiments, at least two support parts of the same height are provided on the bottom surface of the bracket, the bottom surface of the stove top glass is in contact with each of the support parts, a glue cavity is formed between two adjacent support parts, and there is a distance between the glue cavity and the bottom surface of the stove top glass.

[0015] In some embodiments, the stove surface structure further includes an elastic bracket, one end of which is fixed to the connecting portion, and the other end of which is fixed to the stove chassis.

[0016] In some embodiments, the embedded bracket includes four splicing sections with the same cross-section, each of the connecting parts includes a connecting plate and a bolt column, the connecting plate is fixed to the bracket, the bolt column is fixed to the outer side of the connecting plate, and the bolt column has threaded holes at both ends, wherein a relative group of splicing sections has through holes at both ends of the connecting plate.

[0041] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0042] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0043] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0044] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0046] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.

[0047] It should be noted that, when the long and short frames of the current embedded flat frame are gradually tightened with screws, assuming that the screws penetrate the long frame and are threadedly connected to the short frame, the short frame will generate a force to rotate with the screw under the torque of the screw thread. When finally tightened, the connecting end faces between the long and short frames will generate corresponding friction (or additional limiting force) to offset the torque of the screw thread, thereby forming a connection stress between the long and short frames. The existence of the connection stress can easily cause the long frame and the short frame to be unable to be completely flush, forming a step.

[0048] Please combine Figures 1 to 4 As shown, the present application first provides a stove top structure, including an embedded bracket 10 and a stove top glass 20, the embedded bracket 10 includes a plurality of strip-shaped splicing segments 10a spliced ​​and fixed in a horizontal direction, each splicing segment 10a includes a bracket 12 and a connecting portion 13 fixed to each other, and the stove top glass 20 is fixed in the bracket 12; the two adjacent connecting portions 13 with a through hole 131a are the first connecting portions 13a, and the second connecting portion 13b with a fixing hole corresponding to the through hole 131a, the embedded bracket 10 also includes a limiter, the limiter includes a limiter, a positioning portion and a fixing portion that are fixed in sequence, the fixing portion passes through the through hole 131a and is fixed to the inner wall of the fixing hole, the positioning portion is inserted into the through hole 131a and is fitted with the second connecting portion 13b along the axial direction of the through hole 131a, there is a gap between the positioning portion and the inner wall of the through hole 131a along the radial direction of the through hole 131a, and there is a gap between the limiter and the first connecting portion 13a along the axial direction of the through hole 131a.

[0049] In the present application, the pre-limiting between two adjacent splicing sections 10a is completed by a limiting member, and then the cooktop glass 20 is fixed to the bracket 12 in cooperation with the assembly tool to complete the fixation; after the pre-limiting is completed, on the one hand, since the limiting member only plays a limiting role, the first connecting part 13a and the second connecting part 13b will not be pressed tightly, and no connection stress will be generated between the two adjacent connecting parts 13. Therefore, when the subsequent cooktop glass 20 is fixed to the bracket 12, it can ensure that the embedded bracket 10 and the cooktop glass 20 are firmly fixed while avoiding the generation of splicing steps; on the other hand, the splicing sections 10a are pre-limited by connecting them in pairs, so that there is only a small amount of activity between the splicing sections 10a, and no large displacement will occur, which is convenient for further fixation of the cooktop glass 20.

[0050] Preferably, the cooktop glass 20 is fixed in the bracket 12 by gluing; of course, in some other embodiments, the cooktop glass 20 and the bracket 12 can also be fixed by snap-fitting or other commonly used fixing methods, which are not listed one by one in this application.

[0051] Specifically, after the pre-limiting is completed, the position where the connecting stress is generated is at the fitting position of the positioning portion and the second connecting portion 13b, and after the pre-limiting is completed, there is a movable amount between the limiting member and the first connecting portion 13a. Therefore, when tightened, the limiting bolt 14 will not squeeze the first connecting portion 13a, thereby preventing the generation of connecting stress between two adjacent connecting portions 13.

[0052] It is worth mentioning that after the cooktop glass 20 is fixed to the bracket 12, the cooktop structure has been completely limited and fixed. The limiting parts between the pre-limited groups of splicing sections 10a can be installed or not according to actual needs. If not installed, it will not affect the overall fixation of the cooktop structure. If installed, the splicing strips 10a can be connected and fixed to form a whole to prevent falling during transportation.

[0053] Please combine Figure 3 as well as Figure 4 As shown, in some embodiments, the fixing hole is a threaded hole 132a, and the limiting member is a limiting bolt 14; the stud 141 of the limiting bolt 14 is threadedly connected to the threaded hole 132a, and the stud 141 is fitted with the second connecting portion 13b along its own length direction, and the nut 142 of the limiting bolt 14 is the limiting portion.

[0054] After the pre-limiting is completed, the stud 141 is fitted with the second connecting portion 13b along its length direction, there is a gap between the nut 142 and the first connecting portion 13a, and there is a gap between the outer peripheral surface of the stud 141 and the inner wall of the through hole 131a.

[0055] Of course, in some other embodiments, the limiting member may also be fixed to the fixing hole by other means, such as by interference fit between the fixing portion and the fixing hole to complete the fixation, etc., which are not listed one by one in the present application.

[0056] Please combine Figure 3 as well as Figure 4 As shown, in some embodiments, the stud 141 includes a large diameter section 141b close to the nut 142 and a small diameter section 141a away from the nut 142, the large diameter section 141b is a limiting portion, the small diameter section 141a is a fixing portion, the length of the large diameter section 141b is greater than the depth of the through hole 131a, the diameter of the large diameter section 141b is greater than the small diameter section 141a, so as to form a step surface 141c therebetween, the small diameter section 141a is threadedly connected to the threaded hole 132a, and the step surface 141c is in contact with the second connecting portion 13b.

[0057] When the limit bolt 14 is tightened and fixed, the position where the connection stress is generated is on the step surface 141c, the diameter of the large diameter section 141b is smaller than the inner diameter of the through hole 131a, so that a gap is formed between the large diameter section 141b and the through hole 131a in the circumferential direction, and the length of the large diameter section 141b is greater than the depth of the through hole 131a, so that a gap is formed between the nut 142 and the first connecting part 13a, and the above two parts of the gap become the amount of movement when tightening the screw, so that no connection stress is generated between the two connecting parts 13. Of course, in some other embodiments, the limit bolt 14 can also be other structures, as long as the limit bolt 14 is tightened with the second connecting part 13b, there is an amount of movement between the limit bolt 14 and the first connecting part 13a, and the displacement of the first connecting part 13a can be limited.

[0058] It is worth mentioning that in the above embodiment, there will inevitably be a ceiling gap between the bracket 12 and the stove top glass 20, so there are high requirements for the matching accuracy of the two. If the size difference between the two is too large, it will cause a larger ceiling gap. On the one hand, it will affect the overall aesthetics of the stove top structure. On the other hand, the accumulated water may leak into the interior of the stove through the ceiling gap, posing certain safety hazards.

[0059] Please combine Figure 4 as well as Figure 5 As shown, in some embodiments, the cooktop structure further includes a sealing ring 30 surrounding the cooktop glass 20 , and the sealing ring 30 is located between the bracket 12 and the cooktop glass 20 and is closely attached to both in the horizontal direction.

[0060] The sealing ring 30 fills the upward gap between the bracket 12 and the stove top glass 20. In addition to preventing accumulated water from leaking into the interior of the stove through the upward gap and playing a waterproof role, it can also play a buffering role between the bracket 12 and the stove top glass 20 to prevent the stove top structure from making abnormal noises or shaking after long-term use.

[0061] In some embodiments, the cross-section of the sealing ring 30 may be I-shaped, L-shaped, or other shapes, as long as the sealing ring 30 can fit tightly against the inner wall of the bracket 12 to provide waterproof and buffering effects.

[0062] In some embodiments, the top of the sealing ring 30 is flush with the upper surface of the flange 11. It is not difficult to understand that if the sealing ring 30 protrudes from the upper surface of the flange 11, it will affect the discharge of accumulated water when cleaning the stove top glass 20. On the contrary, if the sealing ring 30 is sunken in the ceiling seam, it will cause the accumulated water to remain in the ceiling seam and be difficult to clean.

[0063] Please combine Figure 4 as well as Figure 5As shown, in some embodiments, a mating portion 121 is fixed to the inner side of the bracket 12, the upper surface of the mating portion 121 is flush with the flange 11, and the inner side surface of the mating portion 121 is inclined outward from top to bottom, and the edge of the upper surface of the cooktop glass 20 along the circumferential direction has a chamfer that corresponds to the inner side surface of the mating portion 121.

[0064] The matching between the matching part 121 and the chamfer of the stove top glass 20 can weaken the impact of the upward seam, increase the difficulty of water leakage, and optimize the visual effect of the joint position of the two. The inner side surface of the matching part 121 is inclined outward from top to bottom, and the inner side surface of the matching part 121 can be a plane or a curved surface, as long as it can fit the chamfer of the stove top glass 20.

[0065] Preferably, a matching portion 121 is fixed to the inner side of the bracket 12, and a sealing ring 30 is further provided between the bracket 12 and the stove top glass 20, and the waterproof effect is further optimized by providing the two structures at the same time.

[0066] Please combine Figure 4 as well as Figure 5 As shown, in some embodiments, the upper surface of the flange 11 is inclined downward from the inside to the outside to reduce residual water accumulation on the surface of the flange 11 and further reduce the difficulty of cleaning.

[0067] Glue connection is also a commonly used fixing method. However, due to the fluidity of the colloid and the difference in the amount of glue injected, when the cooktop glass of the built-in stove is glued to the embedded frame, on the one hand, glue overflow is prone to occur, resulting in the colloid overflowing the bonding surface. On the other hand, it is difficult to ensure the uniformity of the glue surface during the extrusion process, and it is easy to have a large deviation in the thickness of the glue layer.

[0068] Please refer to Figure 5 As shown, in some embodiments, at least two support portions 122 of the same height are provided on the bottom surface of the bracket 12, the bottom surface of the cooktop glass is fitted with each support portion 122, a glue cavity 123 is formed between two adjacent support portions 122, and there is a distance between the glue cavity 123 and the bottom surface of the cooktop glass 20; specifically, each support portion 122 is arranged along the length direction of the splicing section 10a, and each support portion 122 is arranged in parallel along the inner and outer directions of the cooker groove 110.

[0069] The stove top glass 20 is supported by the support parts 122 to form a glue cavity 123 for containing glue liquid between adjacent support parts 122. On the one hand, the support parts 122 can block the glue liquid in the glue cavity 123 to prevent the glue liquid from overflowing. On the other hand, the stove top glass 20 preferentially contacts the support parts 122 at the moment of gluing. Therefore, the height of the glue cavity 123 is the thickness of the glue layer after the glue liquid is solidified. Since the heights of the support parts 122 are the same, the heights of each position of the glue cavity 123 are the same, so that the glue surface is uniform and the thickness deviation of the glue surface is relatively small.

[0070] In some embodiments, the support portion 122 protrudes upward from the bottom surface of the bracket 12, and a glue-containing cavity 123 is formed between the support portion 122 and the bottom surface of the bracket 12; or

[0071] The glue containing cavity 123 is recessed downwardly on the bottom surface of the bracket 12, and the bottom surface of the bracket 12 on both sides of the glue containing cavity 123 is the supporting portion 122; or

[0072] The support portions 122 protrude upward from the bottom surface of the bracket 12 , and the bottom surface of the bracket 12 between the support portions 122 is recessed downward to form a glue containing cavity 123 .

[0073] Of course, the support parts 122 and the glue cavity 123 may also be other structures, as long as the support parts 122 have the same height and can support the stove top glass 20, and the glue cavity 123 is located between the support parts 122 and can contain glue. This application does not give examples one by one here.

[0074] Please refer to Figure 5 As shown, in some embodiments, at least one glue guide groove 124 is provided on the bottom wall of the glue cavity 123 along the circumferential direction of the stove groove 110. It is not difficult to understand that if the glue injection amount is too small, the glue liquid cannot completely fill the glue cavity 123, so that there is a glue-deficient area in the glue layer, and if the glue injection amount is too large, the glue liquid will overflow.

[0075] By providing the glue guiding groove 124, on the one hand, glue liquid with an injection amount greater than the volume of the glue containing cavity 123 can be filled into the glue guiding groove 124, thereby ensuring that the glue containing cavity 123 is completely filled with glue liquid while avoiding glue overflow; on the other hand, when the glue liquid in the glue containing cavity 123 is squeezed by the stove top glass 20, excess glue liquid can be filled into the glue guiding groove 124 and quickly supplement the glue-deficient area along the glue guiding groove 124, thereby forming a relatively uniform glue layer in the glue containing cavity 123.

[0076] Specifically, a glue guiding groove 124 is formed on the bottom wall of the glue containing cavity 123 which is in contact with the supporting parts 122 on both inner and outer sides.

[0077] More specifically, the two adhesive guiding grooves 124 are both opened at the end of the adhesive surface close to the supporting portion 122 .

[0078] In some embodiments, S1=(0.7-0.9)S2, wherein S1 is the cross-sectional area of ​​the glue containing cavity 123, and S2 is the sum of the cross-sectional areas of the glue containing cavity 123 and the glue guiding groove 124 in the glue containing cavity 123.

[0079] If the above ratio is too small, the cross-sectional area of ​​the glue guiding groove 124 is too large relative to the glue containing cavity 123. There are two possibilities: the cross-sectional area of ​​the glue containing cavity 123 is small and the cross-sectional area of ​​the glue guiding groove 124 is large. The former may affect the thickness of the glue layer and the firmness of the glue, and the latter may affect the glue guiding speed of the glue guiding groove 124, resulting in the situation that the glue-deficient area cannot be replenished in time.

[0080] If the above ratio is too large, the cross-sectional area of ​​the glue guiding groove 124 is too small relative to the glue containing cavity 123. There are two possibilities: the cross-sectional area of ​​the glue containing cavity 123 is larger and the cross-sectional area of ​​the glue guiding groove 124 is smaller. The former requires too much glue liquid and has high material cost. The latter has relatively poor anti-overflow effect of the glue guiding groove 124 and requires high precision in the amount of glue injected during glue injection.

[0081] In addition, the total volume of the glue containing cavity 123 and the glue guiding groove 124 is V1, and the total glue injection volume during glue injection is V2 (which can be controlled by selecting a suitable pouring head size and corresponding glue injection process parameters), V2 = (0.7~1.1) V1. When the ratio of V2 to V1 is controlled within this range, it is possible to minimize the amount of glue overflow while ensuring that the glue layer thickness is sufficient and the glue is firm, thereby optimizing the glue overflow problem and saving material costs at the same time.

[0082] Please refer to Figure 5 As shown, in some embodiments, a glue storage groove 125 is also provided on the bottom surface of the bracket 12 and is also arranged along the circumferential direction of the stove groove 110 .

[0083] Specifically, the glue storage groove 125 is opened in close contact with the support portion 122 located at the outermost side.

[0084] The high viscosity and density of the glue make it impossible for the glue to instantly flow and fill the glue cavity 123 when it is squeezed by the stove glass 20. Part of the glue will inevitably squeeze out from the gap between the support portion 122 and the stove glass 20. The gap outside the outer support portion 122 is directly connected to the stove glass 20 and the appearance surface of the flush bracket 10 (i.e., the upper surface of the flange 11). If the glue overflows to the appearance surface, it will greatly affect the appearance of the product.

[0085] In this regard, the present application provides a glue storage tank 125 located outside the outer support portion 122. The glue storage tank 125 can perform secondary retention on the overflowed glue, thereby completely eliminating the possibility of the glue overflowing upward along the gap between the embedded bracket 10 and the stove top glass 20 to the appearance surface.

[0086] More specifically, the cross-sectional area of ​​the glue storage groove 125 is greater than the cross-sectional area of ​​the glue guiding groove 124. Since the glue storage groove 125 does not need to consider the influence of the cross-sectional area on the glue guiding efficiency, the glue overflow prevention capability of the glue storage groove 125 can be effectively improved by increasing the cross-sectional area of ​​the glue storage groove 125.

[0087] Please refer to Figure 2 As shown, in some embodiments, the cooktop structure further includes an elastic bracket 40, one end of which is fixed to the connecting portion 13, and the other end is fixed to the cooker chassis; the design of the elastic bracket 40 retains the rigidity in the connection direction, while increasing the elasticity in the assembly direction, so that the elastic bracket 40 can be deformed as the screws are tightened during assembly while ensuring a reliable connection, so as to reduce the connection stress.

[0088] Please combine Figure 2 as well as Figure 3 As shown, in some embodiments, the embedded bracket 10 includes four splicing sections 10a with the same cross-section, and each connecting part 13 includes a connecting plate 131 and a bolt column 132. The connecting plate 131 is fixed to the bracket 12, and the bolt column 132 is fixed to the outer side of the connecting plate 131. Threaded holes 132a are provided at both ends of the bolt column 132. Among them, a relative group of splicing sections 10a has through holes 131a at both ends of its connecting plate 131.

[0089] If the structures of the splicing sections 10a of the long strips and the short strips are different, they must be processed using different molds. However, due to the limitation of processing accuracy, the molds cannot achieve absolute consistency in key dimensions, so splicing steps are easily formed. At the same time, the molds have the problem of subsequent wear, dimensional deviations cannot be controlled, and consistency is poor.

[0090] In the above embodiment, the cross sections of the connecting portions 13 are the same, and thus they can be processed by the same mold, thereby ensuring the consistency of the splicing section 10a and effectively solving the above problem.

[0091] In some embodiments, the underside of the bolt column 132 has an opening.

[0092] Please refer to Figure 6 As shown, in some embodiments, two adjacent splicing segments 10a are spliced ​​at an angle at the corner position of the embedded bracket 10, and the bevel corner tip position of the splicing segment 10a is rounded, so that the corner tip position of the two splicing segments 10a and the splicing position of the corner tips of the two splicing segments 10a are all obtuse angles or rounded angles, thereby preventing the bevel corner tip position from being scratched and also weakening the impact caused by assembly misalignment.

[0093] The rounded corners mentioned above may be arc corners or broken line corners formed by multiple straight lines, and this application does not make any further limitations here.

[0094] Preferably, the bevel angles of two adjacent splicing sections 10a are both 45°, so as to further enhance the splicing integrity and overall aesthetics.

[0095] Please combine Figure 7 as well as Figure 8 As shown, the limit bolt 14 is arranged in the horizontal direction, and the two adjacent flanges 11 are flush and fit together, and the projections of the fitting positions of the two flanges 11 along the vertical direction at least partially overlap with each other; by limiting the projections of the fitting positions of the two adjacent flanges 11 along the vertical direction to at least partially overlap, when the limit bolt 14 is tightened, the overlapping parts of the projections of the two flanges 11 have a tightening tendency driven by the limit bolt 14, thereby improving the gap and step problems between the two.

[0096] Specifically, when the limit bolt 14 is tightened during the assembly process, the limit bolt 14 has a tendency to drive the splicing section 10a where the second connecting portion 13b is located to rotate relative to the other splicing section 10a. Since the projections of the fitting parts of the flanges 11 of the two splicing sections 10a in the vertical direction at least partially overlap, the two splicing sections 10a cannot rotate relative to each other. Tightening the bolts will drive the two flanges 11 to be further squeezed and pressed together, thereby improving the gap and step problems between the two and completing the fastening between the two splicing sections 10a.

[0097] In some embodiments, the fitting surface between the two flanges 11 may be a sloped surface or a stepped surface.

[0098] If the fitting surface is an inclined surface, the inclined surface can play a role of limiting and guiding, so that when the two flanges 11 are subjected to the torsion force generated by tightening the limiting bolts 14 and approaching each other, a tightening trend is generated between the two fitting inclined surfaces to alleviate the gap and step problems.

[0099] In some embodiments, the inclined surface here can be a plane, a curved surface, or a surface formed by connecting and combining multiple surfaces, as long as it has a tendency to drive the two fitting surfaces closer to each other when subjected to a torsional force that brings them closer to each other. This application does not give examples one by one here.

[0100] It should be noted that the limiting effect of the inclined surface in the vertical direction relies on the friction between the two fitting surfaces, so the limiting effect is limited and the effect of improving the step problem is relatively poor.

[0101] If the fitting surface is a step surface, the relative displacement of the two flanges 11 in the vertical direction can be limited after they abut against each other, thereby ensuring that the upper surfaces of the flanges 11 are flush, and effectively solving the step problem.

[0106] S400. Pressing the movable plate of the assembly tool, the movable plate squeezes each splicing section to complete the splicing;

[0107] S500. After the glue is solidified, the cooktop structure is taken out, and the limiting parts are installed in the remaining corresponding through holes and fixing holes.

[0108] Specifically, the assembly tooling includes a base plate 210, a fixed plate 220, a movable plate 230 and a clamp 240. A limiting groove 211 is provided on the upper surface of the base plate 210. The length and width of the limiting groove 211 are greater than the embedded bracket 10. The fixed plate 220 and the movable plate 230 are both L-shaped. The fixed plate 220 is fixed in the limiting groove 211. The movable plate 230 is slidably connected in the limiting groove 211. Multiple clamps 240 are fixed on the upper surface of the base plate 210 for pushing and squeezing the movable plate 230.
