[0042] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The following examples and features in the examples can be combined with each other without conflict.

[0043] The embodiments of the present application disclose a cabinet frame, which is the most basic and important part of the cabinet, responsible for supporting the weight of the entire cabinet, ensuring the stability and durability of the cabinet.

[0044] The front upright beam plays a role in connecting the top and bottom frames, providing structural support and enhancing overall stability.

[0045] Reference Figures 1 to 4 The front upright beam includes an upright profile 10 and a reinforcing profile 20, the inside of the upright profile 10 is formed with a fixing cavity 11 extending along the length direction of the upright profile 10, and the reinforcing profile 20 is inserted into the fixing cavity 11.

[0046] In this way, by forming the fixing cavity 11 extending along the length direction of the column profile 10, and then inserting the reinforcing profile 20 into the fixing cavity 11, the front column beam is formed by the two profiles, and the reinforcing profile 20 can provide higher strength to the front column beam compared to the wood plate filling in the prior art. In addition, the reinforcing profile 20 is basically not affected in strength when drilled, so that the screw 30 can be screwed after drilling to install the hinge on the column profile 10 to connect the cabinet door, which can ensure better connection strength, good load bearing effect, and stronger corrosion resistance compared to the wood plate, thereby ensuring that the front column beam has sufficient strength for a long time and prolonging the service life of the cabinet frame.

[0047] The materials of the reinforcing profile 20 and the column profile 10 are both aluminum alloy, which has the advantages of low cost, high strength, and light weight.

[0048] Specifically, in order to form the fixing cavity 11, the first fixing rib 12 and the second fixing rib 13 are formed on the inner wall of the column profile 10, the first fixing rib 12 and the second fixing rib 13 are arranged opposite to each other in the width direction of the column profile 10, the first fixing rib 12 and the second fixing rib 13 both extend along the length direction of the column profile 10, the first fixing rib 12, the second fixing rib 13, and the inner wall of the column profile 10 together enclose the fixing cavity 11, and the first fixing rib 12 and the second fixing rib 13 can also improve the strength of the column profile 10.

[0049] More specifically, the two opposite side walls in the width direction of the column profile 10 are first side walls 14, and the two opposite side walls in the thickness direction of the column profile 10 are second side walls 15; the first fixing rib 12 is integrally connected to one of the first side walls 14, and the second fixing rib 13 is integrally connected to one of the second side walls 15, which can reduce the volume of the fixing cavity 11 and the reinforcing profile 20, and reduce the material cost while ensuring sufficient strength of the front column beam.

[0050] The first fixing rib 12 includes a first rib portion 121 and a second rib portion 122 integrally connected at an included angle; the first rib portion 121 is integrally connected to the first side wall 14 and extends along the width direction of the column profile 10, and the first rib portion 121, the first side wall 14, the second side wall 15, and the third rib portion 131 and the fourth rib portion 132 of the second fixing rib 13 together enclose the fixing cavity 11 to limit the position of the reinforcing profile 20; the second rib portion 122 is located on the side of the first rib portion 121 away from the fixing cavity 11, so as to form an L-shaped structure with the first rib portion 121 to improve the strength of the column profile 10, and the second rib portion 122 can also increase the contact area with the corner brace in the pull-free handle type cabinet frame to ensure the load bearing reliability of the cabinet frame.

[0051] The second fixed rib 13 comprises a third rib portion 131 and a fourth rib portion 132 which are integrally connected at an included angle; the third rib portion 131 is integrally connected with the second side wall 15 and extends along the thickness direction of the column profile 10; the fourth rib portion 132 extends towards the first fixed rib 12; the third rib portion 131, the fourth rib portion 132, the first side wall 14, the second side wall 15 and the first rib portion 121 of the first fixed rib 12 jointly enclose the fixed cavity 11 to limit the position of the reinforcing profile 20, so as to realize the fixation of the reinforcing profile 20 inside the column profile 10; and the third rib portion 131 and the fourth rib portion 132 which are integrally connected at the included angle form an L-shaped structure, thereby improving the strength of the column profile 10, and meanwhile increasing the contact area with the corner brace in the handle-free cabinet frame, so as to ensure the load-bearing reliability of the cabinet frame.

[0052] In the embodiment, the second fixed rib 13 is integrally connected with two second side walls 15, that is, the second fixed rib 13 is also integrally connected with the other second side wall 15; for example, the second fixed rib 13 further comprises a fifth rib portion 133 which is integrally connected with the fourth rib portion 132 at an included angle, and the third rib portion 131 and the fifth rib portion 133 are respectively located on the opposite sides of the fourth rib portion 132, and the third rib portion 131 and the fifth rib portion 133 are respectively integrally connected with two second side walls 15; in this way, the second fixed rib 13 integrally connected with two second side walls 15 can further improve the strength of the column profile 10, and meanwhile increase the contact area with the corner brace. That is, the second fixed rib 13 can be integrally connected with only one second side wall 15, or can be integrally connected with two second side walls 15.

[0053] In addition, since the second fixed rib 13 is connected with two second side walls 15, the inner cavity of the column profile 10 can be divided into a first cavity chamber 17 and a second cavity chamber 18, and the first cavity chamber 17 and the second cavity chamber 18 are arranged side by side in the width direction of the column profile 10, and the fixed cavity 11 is part of the first cavity chamber 17.

[0054] The lengths of the first fixed rib 12, the second fixed rib 13 and the reinforcing profile 20 are all less than the length of the column profile 10, so that there is a distance between the end portions of the first fixed rib 12, the second fixed rib 13 and the reinforcing profile 20 and the end portion of the column profile 10, that is, there is a distance between the end portions of the first fixed rib 12, the second fixed rib 13 and the reinforcing profile 20 and the end portion of the first cavity chamber 17; in this way, after a corner brace is inserted into the first cavity chamber 17, the corner brace can contact the first fixed rib 12, the second fixed rib 13 and the reinforcing profile 20, thereby playing a supporting role, so as to improve the connection reliability.

[0055] In addition, the other second side wall 15 is provided with support ribs 16, the length direction of the support ribs 16 is the same as the length direction of the column profile 10, the length of the support ribs 16 is less than the length of the column profile 10, and the number of the support ribs 16 is not specifically limited, which mainly serves to improve the strength of the column profile 10, and together with the first fixing rib 12, the second fixing rib 13 and the reinforcing profile 20, serves to increase the contact area with the corner code.

[0056] In this way, the first cavity 17 and the second cavity 18 can be respectively used for two corner codes to be inserted at both ends of the column profile 10, that is, one corner code can be selectively inserted into one end of the first cavity 17 or the other end of the second cavity 18, and the other corner code can be selectively inserted into the other end of the first cavity 17 or the other end of the second cavity 18, which can be flexibly selected according to whether the cabinet is designed to be handle-free or with a handle.

[0057] For example, when the cabinet is designed to be handle-free, that is, the cabinet door has no handle, one corner code at the top is inserted into one end of the first cavity 17, and one corner code at the bottom can be inserted into the other end of the first cavity 17 or the other end of the second cavity 18. When the cabinet is designed to have a handle, that is, the cabinet door has a handle, one corner code at the top is inserted into one end of the second cavity 18, and one corner code at the bottom can be inserted into the other end of the first cavity 17 or the other end of the second cavity 18. In this way, one column profile 10 can realize the handle-free design or the handle design, which has strong versatility, reduces the types of parts, and thus reduces the cost.

[0058] It should be noted that the formation of the fixing cavity 11 is not limited to the above-mentioned implementation by the first fixing rib 12 and the second fixing rib 13 which are separately arranged and opposite in the width direction of the column profile 10, and in some embodiments, the first fixing rib 12 and the second fixing rib 13 can be integrated.

[0059] In the embodiment, the reinforcing profile 20 includes a body 21 and a plurality of reinforcing ribs 22 integrally connected to one face of the body 21, and the body 21 and a part of the reinforcing ribs 22 are in contact with the inner wall for forming the fixing cavity 11.

[0060] Specifically, as shown in FIG. 2, the body 21 of the reinforcing profile 20 is provided with a plurality of reinforcing ribs 22 integrally connected to one face of the body 21, and the body 21 and a part of the reinforcing ribs 22 are in contact with the inner wall for forming the fixing cavity 11. Figures 1 to 4In the shown embodiment, each reinforcing rib 22 has the same shape, but is divided into a middle rib 221 and an outer rib 222 according to the width, that is, all the reinforcing ribs 22 include two middle ribs 221 and at least one outer rib 222 located on the side opposite to each other of the two middle ribs 221 in the width direction of the body 21, the width of the middle rib 221 is smaller than the width of the outer rib 222, and the at least one outer rib 222 can be in contact with the inner wall of the column profile 10 for forming the fixing cavity 11 to define the position of the reinforcing profile 20; meanwhile, each reinforcing rib 22 can increase the contact area of the reinforcing profile 20 with the corner brace and improve the strength of the entire front column beam, and reduce the material usage of the reinforcing profile 20, which can reduce the cost and weight under the premise of ensuring the strength.

[0061] For example Figures 1 to 4 The number of reinforcing ribs 22 in the body 21 is six, and the body 21 is opposite to the second side wall 15 to be able to contact, and the two middle ribs 221 in all the reinforcing ribs 22 are located in the middle, and the other reinforcing ribs 22 are outer ribs 222, and the two outer ribs 222 on the outermost sides are opposite to the first side wall 14 and the third rib portion 131 to be able to contact, and the remaining two outer ribs 222 are opposite to the first rib portion 121 and the fourth rib portion 132 to be able to contact, so as to define the position of the reinforcing profile 20. Meanwhile, each reinforcing rib 22 can increase the contact area of the reinforcing profile 20 with the corner brace and improve the strength of the entire front column beam, and reduce the material usage of the reinforcing profile 20, which can reduce the cost and weight under the premise of ensuring the strength.

[0062] The space between the two adjacent reinforcing ribs 22 can be used for the screw 30 to be put in, and the reinforcing rib 22 clamps the screw 30, so as to limit the radial position of the screw 30, so as to improve the connection reliability of the screw 30 with the column profile 10 and the reinforcing profile 20, and improve the connection strength and bearing effect. For example, the distance between the middle rib 221 and the adjacent outer rib 222 is greater than the distance between the two middle ribs 221, so that each middle rib 221 and the adjacent outer rib 222 can clamp the screw 30.

[0063] In the embodiment as shown in Figures 5 to 7 In the shown embodiment, all the reinforcing ribs 22 are divided into two outer ribs 222 and a middle rib 221 according to the shape, that is, all the reinforcing ribs 22 include two outer ribs 222 and a middle rib 221 located between the two outer ribs 222 in the width direction of the body 21, the outer rib 222 includes a first connecting rib 223 and a second connecting rib 224 connected at an angle, the first connecting rib 223 is integrally connected with the body 21, and the two second connecting ribs 224 are located on the side opposite to each other of the two first connecting ribs 223, and the second connecting rib 224 can be in contact with the inner wall of the column profile 10 for forming the fixing cavity 11.

[0064] For example, the number of reinforcing ribs 22 is Figures 5 to 7 The three shown are two outer reinforcing ribs 222 and an intermediate rib 221 located between the two outer reinforcing ribs 222. The second connecting rib 224 of one outer reinforcing rib 222 is directly opposite to and can contact the first rib 121 and the first sidewall 14. The second connecting rib 224 of the other outer reinforcing rib 222 is directly opposite to and can contact the third rib 131 and the fourth rib 132, thereby defining the position of the reinforcing profile 20. The distance between the intermediate rib 221 and one outer reinforcing rib 222 is greater than the distance between the intermediate rib 221 and the other outer reinforcing rib 222, so that the screw 30 can be driven into the space between the intermediate rib 221 and the outer reinforcing rib 222 where the distance is smaller. The first connecting rib 224 of the intermediate rib 221 and the outer reinforcing rib 222... 3. The bolt position used to fix the hinge can be restricted, acting as a limiting clamp to improve the connection reliability between the screw 30 and the column profile 10 and the reinforcing profile 20, thereby improving the connection strength and load-bearing capacity. The first connecting rib 223 of the outer rib 222, which is farther from the intermediate rib 221, can also clamp the screw 30 between itself and the first sidewall 14. The screw 30 can also abut against the second connecting rib 224 of the outer rib 222. This not only restricts the position of the screw 30 but also ensures the tightness of the reinforcing profile 20 within the column profile 10, improving the connection reliability between the screw 30 and the column profile 10 and the reinforcing profile 20, increasing the connection strength and load-bearing capacity, while also reducing the number of reinforcing ribs 22 and saving materials. The L-shaped outer rib 222, formed by the angled, integrally connected first connecting rib 223 and second connecting rib 224, better ensures the strength of the reinforcing profile 20, thereby improving the overall strength of the front column beam.

[0065] Of course, in some embodiments, the reinforcing profile 20 can also be a solid profile or other types of construction, as long as it is located within the fixing cavity 11. The reinforcing profile 20 can be inserted into the fixing cavity 11 as a whole, or two or more reinforcing profiles 20 can be inserted into the fixing cavity 11 sequentially along the length of the column profile 10.

[0066] In the embodiment, the first rib 141, the second rib 142 and the third rib 143 are arranged on the outside of one of the opposite side walls of the column profile 10 in the width direction, thereby improving the strength of the column profile 10. Specifically, the first rib 141, the second rib 142 and the third rib 143 are arranged on the outside of one of the first side walls 14, and the first rib 141, the second rib 142 and the third rib 143 are arranged in the thickness direction of the column profile 10, the first slot 144 is formed between the first rib 141 and the second rib 142, and the second slot 145 is formed between the second rib 142 and the third rib 143. The thickness of the first rib 141 is greater than the thickness of the second rib 142 and the thickness of the third rib 143, and the slot width of the first slot 144 is less than the slot width of the second slot 145. In this way, during the process of manufacturing the cabinet frame by using the column profile 10, the first rib 141 is outward, the first slot 144 can be embedded into the decorative plate, and the screw is locked into the plate body through the first rib 141. Compared with the prior art, the connection reliability can be ensured, the cabinet strength is improved, and the second slot 145 can be used to clamp the plate body such as the ceramic tile.

[0067] Exemplarily, the column profile 10 and the reinforcing profile 20 are integrally formed, which is convenient for manufacturing and low in cost.

[0068] In summary, the embodiment of the present application discloses a front column beam and a cabinet frame. The fixing cavity 11 extending in the length direction of the column profile 10 is formed in the inside of the column profile 10, and then the reinforcing profile 20 is inserted into the fixing cavity 11. In this way, the front column beam is composed of two profiles, and the reinforcing profile 20 can bring higher strength to the front column beam compared with the wood plate filling in the prior art. When the cabinet door is installed, the drilling of the reinforcing profile 20 basically does not affect the strength of the reinforcing profile 20. In this way, the drilling and screwing 30 are used to install the hinge on the column profile 10 to connect the cabinet door, so that the connection strength can be ensured, the bearing effect is good, and the corrosion resistance is stronger than that of the wood plate. Therefore, the front column beam can have sufficient strength for a long time, and the service life of the cabinet frame is prolonged.

[0069] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
