Description

TECHNICAL FIELD

[0001] The utility model relates to range hood technical field especially, relates to a range hood's fender board protection angle, fender board and range hood. BACKGROUND

[0002] Range hood is a kind of kitchen appliance that purifies kitchen environment.Range hood includes casing, and the air inlet of casing is equipped with deflectable fender board, and fender board material is glass panel generally, and in the use process of range hood, it will be opened and closed by motor drive.Fender board is generally glass material, in the opening process of fender board or after opening, the head of user is easily collided with the corner of fender board and is injured, therefore, need to install soft material in the corner of fender board, prevent user from being injured by directly colliding with the sharp corner of fender board, provide a buffer protection function.At present, the main protection function of corner on market is mainly two kinds, one kind is that soft material is pasted in the corner of glass panel by double-sided adhesive, and the adhesive of this kind of soft material corner is double-sided adhesive, in the process of oil fume environment and user cleaning and wiping, double-sided adhesive is easily polluted by oil fume, gradually loosens until falls off.On the other hand, the adhesive corner cannot be repeatedly disassembled, is inconvenient to use, cannot be reused, double-sided adhesive is invalid after falling off, ordinary double-sided adhesive replaces the poor adhesive effect, and it is extremely easy to fall off.The other kind of corner is that adhesive tape is formed by extrusion, and the edge is closed in the forming process, and is mainly applied to the protection of relatively long glass edge.The clamping force of this extruded adhesive tape is insufficient, if only a small section of the corner of fender board is provided, it is insufficient to provide sufficient clamping force, especially after being heated, the clamping force is further weakened, and it is easy to fall off.On the other hand, the adhesive tape is poorly fitted, and needs to be bent in the glass corner position during use, and cannot be pasted to the surface.

[0003] Therefore, the fender board protection corner of the existing range hood still needs to be further improved. UTILITY MODEL CONTENTS

[0004] The first technical problem to be solved by the utility model is to provide a fender board protection corner of range hood, which can be firmly installed to the corner of fender board and can be reused according to the prior art.

[0005] The second technical problem to be solved by the utility model is to provide a fender board with the above protection corner according to the prior art.

[0006] The third technical problem to be solved by the utility model is to provide a range hood with the above fender board according to the prior art.

[0007] The technical scheme adopted by the utility model to solve the first technical problem is as follows:

[0008] The flexible protective sleeve is L-shaped as a whole, and includes a first sleeve part and a second sleeve part arranged at an angle, the cross section of the first sleeve part and the cross section of the second sleeve part are both U-shaped, thereby forming a mounting notch for the corner of the smoke baffle to be clamped therein.

[0009] The rigid framework is arranged inside the first sleeve part and / or the second sleeve part, and the cross section of the rigid framework is also a matched U-shaped structure.

[0010] The "L-shaped flexible protective sleeve" described above is not limited to the first sleeve part and the second sleeve part being perpendicular, that is, the angle between the first sleeve part and the second sleeve part can be slightly greater than or slightly less than 90° (such as the floating angle can be 5°).

[0011] The "flexible" in the "flexible protective sleeve" described above can be understood as the protective sleeve adopting a material with lower hardness than the rigid framework, such as silicone, rubber, plastic, etc. The specific material can be selected according to the use environment, such as silicone, rubber, plastic with appropriate hardness, wherein the hardness can be determined according to the protection ability generated by collision, and the material can be selected according to the use environment, such as a material resistant to oil stains and easy to clean.

[0012] The rigid framework described above can adopt a metal piece or other materials with relatively large hardness, such as a metal piece. According to different manufacturing processes and use environments, the metal piece can be selected from ordinary cold-rolled sheets, galvanized sheets, stainless steel sheets, etc. If the rigid framework is exposed, a stainless steel sheet can be selected, and if the rigid framework is completely embedded in the protective sleeve, an ordinary sheet can be selected. The thickness of the sheet of the rigid framework determines the hand pressure experience and clamping size during use, so the thickness should not be too large or too small, and is generally 0.2-0.5 mm. The metal material rigid framework can be bent into a U-shaped structure to provide symmetrical clamping force. The side of the U-shaped structure is a finger compression edge, so the height should be ≥5 mm to facilitate pressing, and also to ensure the length of the compression edge and prevent it from slipping under stress.

[0013] Generally, the corresponding rigid framework can be arranged only in one of the first sleeve part and the second sleeve part, but in order to further ensure the firmness of the protective angle clamped on the smoke baffle, the rigid framework includes a first framework arranged in the first sleeve part and a second framework arranged in the second sleeve part.

[0014] The first skeleton and the second skeleton described above can be an integral piece or a split piece. When a split piece is used, the protective sleeve can be made by a potting process to embed the first skeleton and the second skeleton therein, or can be made by an assembly method. Specifically, the first sheath portion is provided with a first mounting groove for embedding the first skeleton therein, and the end portion of the first sheath portion away from the second sheath portion is provided with a first socket penetrating the first mounting groove. The second sheath portion is provided with a second mounting groove for embedding the second skeleton therein, and the end portion of the second sheath portion away from the first sheath portion is provided with a second socket penetrating the second mounting groove. After the protective sleeve is manufactured, the first skeleton and the second skeleton are respectively loaded into the first mounting groove and the second mounting groove of the protective sleeve through the corresponding sockets on the side of the protective sleeve.

[0015] After the first skeleton and the second skeleton are assembled in place, the first socket and the second socket are closed by a sealing glue to prevent the first skeleton and the second skeleton from coming out. Of course, it is conceivable that the first socket and the second socket can also be closed by a detachable sealing member, or can be in an open state without being closed.

[0016] When the first skeleton and the second skeleton are split pieces, the protective corner as a whole can allow a larger distortion or deformation, but this has a certain influence on the overall service life of the protective corner and the firmness of the clamping smoke baffle. Therefore, in order to ensure the overall strength of the protective corner, in another feasible solution, the first skeleton and the second skeleton are an integral piece.

[0017] As an improvement, the first skeleton includes two opposite first clamping plates and a first connecting plate connected between the two first clamping plates, the second skeleton includes two opposite second clamping plates and a second connecting plate connected between the two second clamping plates, the first connecting plate has a gap between the two end portions adjacent to the second connecting plate to form a hollow corner portion, and at least one first clamping plate of the first skeleton is connected to the second clamping plate on the same side of the second skeleton. The corner portion of the rigid skeleton is designed to be hollow, i.e., no metal plate material is arranged at the sharp corner position, and the flexible material can be further thickened to provide good buffering protection.

[0018] Further improvement, the part connected between the first clamping plate and the second clamping plate is configured as a first arc-shaped plate with a rounded transition, and the first clamping plate, the first arc-shaped plate and the second clamping plate are sequentially connected to form an L-shaped plate body structure extending in the same plane.

[0019] As another feasible solution of the integrated design of the first skeleton and the second skeleton, the first skeleton comprises two opposite first clamping plates and a first connecting plate connected between the two first clamping plates, and the second skeleton comprises two opposite second clamping plates and a second connecting plate connected between the two second clamping plates, and the two ends of the first connecting plate adjacent to the second connecting plate are connected.

[0020] Further improvement, the part connected between the first connecting plate and the second connecting plate is configured as a second arc-shaped plate with a rounded transition.

[0021] As an improvement, the first skeleton comprises two opposite first clamping plates and a first connecting plate connected between the two first clamping plates, and the first clamping plate is provided with a first opening at the position where the first clamping plate is connected with the first connecting plate, and the second skeleton comprises two opposite second clamping plates and a second connecting plate connected between the two second clamping plates, and the second clamping plate is provided with a second opening at the position where the second clamping plate is connected with the second connecting plate. The design of the first opening and the second opening can adjust the force when the user presses the side of the rigid skeleton, making it easier to press, and further limiting the position of the rigid skeleton in the protective sleeve to avoid sliding under stress during use.

[0022] As an improvement, the first sleeve part and the second sleeve part each comprise opposite clamping edges and a connecting edge connected between the two clamping edges, and the thickness of the connecting edge is greater than the thickness of the clamping edge. Due to the limitation of the use position, the thickness of the three sides of the protective corner should be reasonably designed. One side of the two sides of the U-shaped symmetry (i.e. the clamping edge) is clamped between the smoke baffle and the machine body, and in order to avoid stress on the smoke baffle, the thickness of this side should not be too large. The other side is the outside, which is the surface that the user can contact when cleaning the smoke baffle in daily life, and in order to avoid a large step on the outer surface of the smoke baffle, it also cannot be too thick, and the specific thickness can be adjusted according to the limitation of the use environment, and should not exceed 3mm. The two sides of the U-shaped structure are symmetrically designed, which is beneficial to the generalization of the parts, and the same part can be installed on both sides. The bottom surface of the U-shaped structure (i.e. the connecting edge) is the protective surface, and the thicker the better under the allowable conditions, so that there is more flexible material on the edge and the corner, which can provide better buffering and protection.

[0023] As an improvement, the inner wall surface of the mounting slot of the protective sleeve is a smooth wall surface that can be attached to the outer wall surface of the smoke baffle. Since the inner wall surface of the mounting slot of the protective sleeve contacts the outer wall surface of the smoke baffle, the inner wall surface of the mounting slot of the protective sleeve is designed as a smooth surface, which can ensure a large adsorption force with the outer wall surface of the smoke baffle, and is more conducive to the fixation of the protective corner.

[0024] The process of wrapping the rigid framework with the protective sleeve can be a fully closed full encapsulation mode or a encapsulation mode with positioning, and in order to facilitate positioning, the protective sleeve is also provided with a hole penetrating from the inner wall of the mounting slot to the inside of the protective sleeve to expose the rigid framework.

[0025] The utility model solves the second technical problem adopts the technical scheme: a fender of oil fume suction is used, including fender main part and the corner position of installing of fender main part's corner, the corner of protective corner of fender of oil fume suction adopts above.

[0026] As an improvement, in order to further improve the buffering and anti-collision effect, the fender main body has a rounded corner portion, and the mounting slot of the flexible protective sleeve also has a rounded corner portion at the corresponding position, and the curvature radius of the rounded corner portion of the flexible protective sleeve is smaller than that of the rounded corner portion of the fender main body. Since the fender usually collides with the glass corner portion, and the corner portion is the most vulnerable position. First, the protective sleeve of the protective corner is protected by flexible material, which uses the elasticity and isolation of flexible material to reduce the pain of collision and avoid injury caused by direct collision with the glass corner portion; secondly, the corner portion of the fender of the oil fume suction machine generally has a certain fillet, and the fillet of the inner side of the protective sleeve is designed to be smaller than the fillet of the glass panel, which on the one hand ensures that the inner side of the protective sleeve can be installed to the bottom, and on the other hand, due to the angle difference between the fillet of the inner side of the protective sleeve and the fillet of the glass, a certain air layer is formed, which can further realize the buffering effect. The curvature radius of the fillet portion of the first arc-shaped plate should be designed as large as possible to avoid the fillet portion of the first arc-shaped plate from being in the above-mentioned air layer with a certain fillet difference, so as to further avoid collision and contact with metal.

[0027] The utility model solves the third technical problem adopts the technical scheme: an oil fume suction machine, including the casing and the fender of rotating in the casing, the fender adopts the fender above.

[0028] Compared with the prior art, the utility model has the advantages that: the protective corner structure with the rigid framework embedded in the flexible protective sleeve effectively solves the problem of fixing the protective corner on the glass panel, and can realize repeated installation and use. At the same time, due to the setting of the rigid framework, the flexible protective sleeve can be provided with rigid support, so that it has clamping force after being clamped and peeled off, and it will not easily fall off due to external force and other factors. On the other hand, the rigid framework can press the flexible protective sleeve tightly on the glass panel to form an adsorption effect, so there is a large clamping force, and it is not easy to fall off after installation. In addition, even if it falls off due to repeated external force, it can be repeatedly installed and used by pressing the rigid framework to make it tighten. BRIEF DESCRIPTION OF DRAWINGS

[0040] Embodiment 1

[0041] Figures 1-3An optimal embodiment of the smoke baffle protection corner of the range hood is shown. The smoke baffle protection corner of the range hood comprises a flexible protection sleeve 1 and a rigid framework 2. The flexible protection sleeve 1 is L-shaped as a whole and comprises a first sleeve part 11 and a second sleeve part 12 arranged at an angle. The flexible protection sleeve 1 of the L shape is not limited to the first sleeve part 11 being perpendicular to the second sleeve part 12, that is, the angle between the first sleeve part 11 and the second sleeve part 12 can be slightly greater than or slightly less than 90° (for example, the floating angle can be 5°). The cross section of the first sleeve part 11 and the cross section of the second sleeve part 12 are both U-shaped, thereby forming a mounting slot 10 for clamping the corner of the smoke baffle. The protection sleeve 1 can be made of a material with a lower hardness than the rigid framework 2, such as silicone, rubber, plastic, etc. The specific material can be selected according to the use environment, for example, silicone, rubber, plastic, etc. with appropriate hardness can be selected, wherein the hardness can be determined according to the protection capability generated by the collision, and the material can be selected according to the use environment, for example, a material resistant to oil stains and easy to clean can be selected.

[0042] The rigid framework 2 is arranged inside the first sleeve part 11 and / or the second sleeve part 12. Generally, it is also feasible to arrange the corresponding rigid framework 2 only in one of the first sleeve part 11 and the second sleeve part 12. In the preferred embodiment, in order to further ensure the firmness of the protection corner clamped on the smoke baffle, the rigid framework 2 comprises a first framework 21 and a second framework 22. The first framework 21 and the second framework 22 of the embodiment are separate components, the first framework 21 is arranged in the first sleeve part 11, and the second framework 22 is correspondingly arranged in the second sleeve part 12. The cross section of the first framework 21 and the second framework 22 is also U-shaped structure, which is matched with the U-shaped cross section of the first sleeve part 11 and the second sleeve part 12. Generally, the rigid framework 2 can be made of metal or other materials with relatively large hardness, for example, when made of metal, the material is selected according to the manufacturing process and the use environment, such as ordinary cold-rolled plate, galvanized sheet, stainless steel sheet, etc. The rigid framework 2 can be made of stainless steel sheet if it is exposed, or ordinary sheet material if it is completely embedded in the protection sleeve 1. The thickness of the sheet material of the rigid framework 2 determines the hand pressure experience and clamping size during use, so the thickness should not be too large or too small, generally 0.2-0.5mm. The rigid framework 2 made of metal material can be bent into a U shape to enable symmetrical clamping and provide symmetrical holding force. The side of the U shape is the finger compression edge, so the height should be greater than or equal to 5mm, which is convenient for pressing and can also ensure the length of the compression edge and prevent it from slipping under stress.

[0043] The first framework 21 and the second framework 22 of the embodiment are separate components, the protection sleeve 1 can be made by a rubber coating process to embed the first framework 21 and the second framework 22, or can be made by an assembly method. Figure 1 and Figure 3The first sheath part 11 is provided with a first installation slot 111 for embedding the first skeleton 21, and the end of the first sheath part 11 away from the second sheath part 12 is provided with a first socket 112 penetrating the first installation slot 111, both of which are U-shaped, and the first skeleton 21 can be installed into the first installation slot 111 from the first socket 112. Similarly, the second sheath part 12 is provided with a second installation slot 121 for embedding the second skeleton 22, and the end of the second sheath part 12 away from the first sheath part 11 is provided with a second socket 122 penetrating the second installation slot 121, both of which are U-shaped, and the second skeleton 22 can be installed into the second installation slot 121 from the second socket 122. After the first skeleton 21 and the second skeleton 22 are assembled in place, the first socket 112 and the second socket 122 can be closed by sealing glue to prevent the first skeleton 21 and the second skeleton 22 from falling out.

[0044] Since the first skeleton 21 and the second skeleton 22 of the embodiment are designed in a split manner, after the two skeletons are installed in the two sheath parts of the protective sleeve 1, the corner position of the protective corner is basically the flexible material of the protective sleeve 1, without the rigid skeleton 2 material, so that the elasticity and isolation of the flexible material can be effectively utilized to reduce the pain of collision and avoid the user from being injured by directly colliding with the corner of the glass.

[0045] The first skeleton 21 includes two opposite first clamping plates 211 and a first connecting plate 212 connected between the two first clamping plates 211. The second skeleton 22 includes two opposite second clamping plates 221 and a second connecting plate 222 connected between the two second clamping plates 221. Correspondingly, the first sheath part 11 and the second sheath part 12 each include opposite clamping edges 101 and a connecting edge 102 connected between the two clamping edges 101. Due to the limitation of the use position, the thickness of the three sides of the protective corner (i.e., the two clamping edges 101 and the connecting edge 102) should be reasonably designed. One side of the two sides of the U-shaped symmetry (i.e., the two clamping edges 101) is clamped between the fender and the machine body, and in order to avoid stress on the fender, the thickness of this side should not be too large. The other side is the outer side that the user can contact during daily cleaning of the fender, and in order to avoid a large step being formed on the outer surface of the fender, the thickness of this side should also not be too large. The specific thickness can be adjusted according to the limitation of the use environment, and should not exceed 3 mm. The two sides of the U-shaped structure are designed symmetrically, which is beneficial to the generalization of parts, and the same part can be installed on both sides. The bottom side of the U-shaped structure (i.e., the connecting edge 102) is the protective side, and the thicker the better under the allowable conditions, so that there is more flexible material on the edge and the corner, which can achieve better buffering and protection effects.

[0046] The inner wall of the installation slot 10 of the protective sleeve 1 is designed as a smooth wall surface that can be attached to the outer wall surface of the smoke baffle. Since the inner wall of the installation slot 10 of the protective sleeve 1 contacts the outer wall of the smoke baffle, the inner wall of the installation slot 10 of the protective sleeve 1 is designed as a smooth surface to ensure a greater adsorption force with the outer wall of the smoke baffle, which is more conducive to the fixation of the protective corner.

[0047] The U-shaped gap of the protective corner of the embodiment is generally consistent with the thickness of the smoke baffle. During use, in order to obtain a greater clamping force, the user can press the U-shaped gap of the protective corner with fingers to make the U-shaped gap slightly narrower and then install it at the corner of the glass, so as to obtain a greater clamping force. Of course, the U-shaped gap should not be too small to avoid inconvenience in installation.

[0048] The protective sleeve 1 and the rigid framework 2 of the protective corner of the embodiment are combined and installed, that is, after the protective sleeve 1 is manufactured, the metal fastener is installed in the interior of the protective sleeve 1 through the side insertion port, and the side insertion port is closed by adhesive to achieve complete sealing. Although this method can completely seal the metal part, the process is more and the cost is relatively high. It is conceivable that the process of wrapping the rigid framework 2 with the protective sleeve 1 can also adopt a fully sealed full-gluing method or a gluing method with positioning. When the gluing method with positioning is adopted, in order to facilitate positioning, a hole 100 that is exposed from the inner wall of the installation slot 10 to the interior of the protective sleeve 1 can be provided on the protective sleeve 1.

[0049] The protective corner structure of the embodiment, in which the rigid framework 2 is embedded in the flexible protective sleeve 1, effectively solves the fixation problem of the protective corner on the glass panel, and can realize repeated installation and use. At the same time, due to the provision of the rigid framework 2, the flexible protective sleeve 1 can be provided with rigid support, so that it has clamping force after being clamped and peeled off and will not easily fall off due to external force and other factors. On the other hand, the rigid framework 2 can press the flexible protective sleeve 1 against the glass panel to form an adsorption effect, so there is a greater clamping force, and it is not easy to fall off after installation. In addition, even if it falls off due to repeated external force, it can be repeatedly installed and used by pressing the rigid framework 2 to make it tighten.

[0050] The present embodiment also relates to a fender for an oil fume extractor, comprising a fender body and a protective corner installed at a corner position of the fender, wherein the protective corner is the protective corner of the fender of the oil fume extractor as described above. The fender has a rounded corner, and the installation slot 10 of the flexible protective sleeve 1 also has a rounded corner at the corresponding position, wherein the curvature radius of the rounded corner of the flexible protective sleeve 1 is smaller than that of the rounded corner of the fender. Since the fender usually collides with the glass corner, the corner position is the position where the user is most likely to be injured. The protective sleeve 1 of the protective corner of the present embodiment is protected by a flexible material, which utilizes the elasticity and isolation of the flexible material to reduce the pain of collision and avoid the user from being injured by directly colliding with the glass corner. The corner of the fender of the oil fume extractor generally has a certain fillet, and the curvature radius of the fillet at the inner side of the protective sleeve 1 is smaller than that of the glass panel, which can ensure that the inner side of the protective sleeve 1 can be installed to the bottom, and the air layer formed between the fillet at the inner side of the protective sleeve 1 and the glass fillet due to the angle difference can further achieve the buffering effect.

[0051] The present embodiment also relates to an oil fume extractor, comprising a casing and a fender rotatably arranged on the casing, wherein the fender is the fender with the protective corner as described above.

[0052] Embodiment 2

[0053] Figures 4-7 Another preferred embodiment of the protective corner of the fender of the oil fume extractor of the present utility model is shown. The main difference between the present embodiment and embodiment 1 is that the rigid framework 2 is different, and the first framework 21 and the second framework 22 of the rigid framework 2 of the present embodiment are designed as a whole. The first framework 21 of the present embodiment also comprises two opposite first clamping plates 211 and a first connecting plate 212 connected between the two first clamping plates 211. The second framework 22 also comprises two opposite second clamping plates 221 and a second connecting plate 222 connected between the two second clamping plates 221. Among them, the two end portions adjacent to the first connecting plate 212 and the second connecting plate 222 have a gap to form a hollow corner, and at least one first clamping plate 211 of the first framework 21 is connected with the second clamping plate 221 on the same side of the second framework 22. As shown in the figure, Figure 5It is shown that only one first clamping plate 211 of the first skeleton 21 is connected with the second clamping plate 221 of the second skeleton 22 on the same side, wherein the connected part between the first clamping plate 211 and the second clamping plate 221 is configured as a first arc-shaped plate 201 with a rounded corner transition, and the first clamping plate 211, the first arc-shaped plate 201 and the second clamping plate 221 are connected in sequence to form an L-shaped plate body structure extending in the same plane. The curvature radius of the rounded corner part of the first arc-shaped plate 201 should be designed as large as possible to avoid the rounded corner part of the first arc-shaped plate 201 appearing in the air layer of the rounded corner difference (the rounded corner difference between the inner rounded corner of the protective sleeve 1 and the rounded corner of the glass), so that the user can avoid colliding with the metal skeleton when colliding with the protective corner.

[0054] Similar to the effect of the rigid skeleton 2 designed in the embodiment, the corner part of the rigid skeleton 2 of the present embodiment adopts a hollow design, that is, no metal plate material is arranged at the sharp corner position, and the flexible material can be further thickened to provide good buffering protection effect.

[0055] Since the rigid skeleton 2 is designed as a whole, that is, the rigid skeleton 2 is also a bent L-shaped structure as a whole, the protective corner of the present embodiment is preferably designed as a fully closed full encapsulation method or a encapsulation method with positioning. For example, Figure 6 It is shown that the encapsulation method with positioning is adopted, and the protective sleeve 1 of the present embodiment is provided with a hole 100 which is formed from the inner wall of the mounting slot 10 to the inside of the protective sleeve 1 to expose the rigid skeleton 2.

[0056] The position where the first clamping plate 211 of the present embodiment meets the first connecting plate 212 is provided with a first opening 203, and the position where the second clamping plate 221 meets the second connecting plate 222 is provided with a second opening 204. The design of the first opening 203 and the second opening 204 can adjust the force when the user presses the side of the rigid skeleton 2, so that it is easier to press, wherein the number or opening area of the first opening 203 and the second opening 204 is different, and the ability of the U-shaped slot of the first skeleton 21 and the second skeleton 22 to deform under external force is different, which can be selected according to actual needs. In addition, the design of the first opening 203 and the second opening 204 can further limit the position of the rigid skeleton 2 in the protective sleeve 1 to avoid the problem of sliding under stress during use. It can be thought that the first opening 203 and the second opening 204 can also be provided on the first skeleton 21 and the second skeleton 22 designed in the embodiment 1.

[0057] Embodiment 3

[0058] Figure 8 and Figure 9Another preferred embodiment of the smoke baffle protection corner of the range hood is shown in the utility model. The main difference between this embodiment and embodiment 1 is that the rigid framework 2 is different, and the first framework 21 and the second framework 22 of the rigid framework 2 of this embodiment are designed as a whole.

[0059] The first framework 21 of this embodiment also comprises two opposite first clamping plates 211 and a first connecting plate 212 connected between the two first clamping plates 211. The second framework 22 also comprises two opposite second clamping plates 221 and a second connecting plate 222 connected between the two second clamping plates 221. The difference between this embodiment and the integrally designed rigid framework 2 in embodiment 2 is that the first connecting plate 212 of the first framework 21 is connected between the two end portions adjacent to the second connecting plate 222 of the second framework 22, and specifically, the part connected between the first connecting plate 212 and the second connecting plate 222 is configured as a second arc-shaped plate 202 with a rounded corner transition, that is, the L-shaped corner portion of the rigid framework 2 is not hollowed out, sacrificing a certain protection, but the overall structure is more stable, the metal framework blanking layout is convenient, and the waste is less.

[0060] The position where the first clamping plate 211 of the first framework 21 of this embodiment meets the first connecting plate 212 can also be provided with a first opening 203 according to needs, and the position where the second clamping plate 221 of the second framework 22 meets the second connecting plate 222 can also be provided with a second opening 204.

[0061] As in embodiment 2, since the rigid framework 2 of this embodiment is designed as a whole, that is, the rigid framework 2 is also a bent L-shaped structure as a whole, therefore, the protection corner of this embodiment is preferably in a fully closed full rubber coating mode or in a rubber coating mode with positioning.
