See the following for details.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A cabinet with doors that can be replaced left and right provided by the utility model includes a door panel body. The door panel body is horizontally and vertically unfolded. The upper and lower edges in front of the door panel body are horizontally provided with horizontal flanging parts, and the two side edges in front of the door panel body are vertically provided with vertical flanging parts. And the directions of the horizontal flanging parts and the vertical flanging parts respectively correspond to the horizontal part and the vertical part of the corner at the combined position of the cabinet body.

[0007] Installation base parts are combined and arranged at the upper and lower positions of the vertical flanging parts. The installation base parts are all detachably fixed with quick-release connectors. And the outer parts of the quick-release connectors at the upper and lower positions, which are far away from each other, all penetrate out of the outside of the corresponding horizontal flanging parts, so as to install and support the lower part of the quick-release connectors through the installation base parts, and at the same time complete the rotational connection of the door panel body at the combined position of the cabinet body through the quick-release connectors.

[0008] Preferably, the mounting base members each include mounting fins and bending openings. The edges of the mounting fins at the upper and lower positions that are close to each other are fixed edges. The bending openings are provided at both the upper and lower positions of the vertical flanging portion. Only the fixed edge of the mounting fin is fixedly connected to one side of the inner wall of the corresponding bending opening, and the mounting fins are all arranged horizontally.

[0009] Preferably, the quick-release connectors each include a mounting hole, a mating hole, and a rotating shaft body. The mounting holes are vertically provided at the positions of the mounting fins close to the vertical flanging portion. The mating holes are vertically provided at the positions of the horizontal flanging portion close to the vertical flanging portion, and the mating holes and the mounting holes are vertically coaxially aligned. The upper and lower ends of the rotating shaft body respectively pass through the corresponding mounting hole and the mating hole coaxially. A spring is coaxially and clearance-fitted around the part of the rotating shaft body between the corresponding horizontal flanging portion and the mounting fin, and sleeves are fixed at both ends of the spring. The sleeves are sleeved around the corresponding rotating shaft body in a coaxially sliding fit manner, and the upper and lower sleeves respectively abut against the surfaces of the adjacent horizontal flanging portion and the mounting fin.

[0010] Preferably, the rotating shaft body and the corresponding mounting hole are coaxially and clearance-fitted, and the rotating shaft body and the corresponding mating hole are coaxially and sliding-fitted.

[0011] Preferably, the outer diameter of the sleeve is larger than the aperture of the mounting hole.

[0012] Preferably, when the sleeves respectively abut against the surfaces of the adjacent horizontal flanging portion and the mounting fin, the springs are all in a compressed state.

[0013] Preferably, the horizontal flanging portion is provided with passing openings at the side positions beside the rotating shaft body to enable the rotating shaft body and the sleeves to pass through smoothly.

[0014] Preferably, a handle portion for convenient gripping is fixedly installed on the back surface of the door panel body at the side away from the mounting fin.

[0015] The above-mentioned cabinet has replaceable door panels on the left and right. Specifically, when the door panel body and the cabinet are used in combination, the quick-release connectors are detachably assembled at the upper and lower positions on one side of the door panel body through the mounting base. The door panel body can be detachably assembled at the edge of the cabinet by coaxially cooperating with the upper and lower holes at the cabinet edge assembly positions. At the same time, the quick-release connectors at the upper and lower positions are symmetrically distributed, and then the door panel body can be smoothly assembled at the edge assembly position on the other side of the cabinet by axially flipping the door panel body around the handle. The function of the door panel body being able to be replaced and installed on the left and right is realized, which improves the applicability of the door panel body. Specifically, when the door panel body and the cabinet body are assembled and disassembled, when assembling, since the door panel body is provided with the transverse flange part and the vertical flange part to respectively correspond to the horizontal part and the vertical part of the corner of the cabinet body assembly position, and at the same time, the mounting base part of the vertical flange part is detachably assembled and fixed with the quick-release connecting piece, so that the inner end of the rotating shaft body of the quick-release connecting piece passes through the object-passing opening and then slides vertically down along the mounting hole, and the spring is compressed by the ring, so that the outer end of the rotating shaft body can be smoothly moved to the lower part of the inner end coaxially located in the matching hole, and at the same time, the outer end of the rotating shaft body can be smoothly exposed through the outer end of the matching hole through the outer end of the rotating shaft body. The outer end of the matching hole is exposed in a manner that it can be higher than the outside of the horizontal flange portion and can be smoothly coaxially plugged into the hole position of the cabinet assembly position. The door panel body and the cabinet body are simply and easily assembled with the help of the quick-release connector, which makes it easy to quickly complete the rotational connection of the door panel body in the cabinet assembly position with the help of the quick-release connector. When disassembling, it is only necessary to pull down the bottom end of the rotating shaft body so that the inner end of the rotating shaft body can be received below the outer end of the matching hole and detached from the hole position of the cabinet assembly position. Then, keeping the rotating shaft body in the pulled-down state, the door panel body can be translated and disassembled from the cabinet assembly position. The door panel body and the cabinet body are simply and easily assembled with the help of the quick-release connector, which makes it easy to subsequently complete the rotational connection of the door panel body with the help of the quick-release connector. To quickly separate the door panel body and the cabinet body for maintenance and replacement, and specifically to the installation base component, since the installation base component is specifically the installation wing that only connects the fixed edge with the bottom edge of the bent opening, the installation base component can be quickly set up by bending the installation wing around the fixed edge from a vertical state to a horizontal state, and the installation base component can be quickly hidden by bending the installation wing around the fixed edge from a horizontal state to a vertical state. The setting and hiding methods of the installation base component are simple and easy to implement, and it is convenient to quickly process the vertical flange portion to obtain the installation base component, and then facilitate the vertical flange portion to be smoothly applied to the actual combination of the door panel body and the cabinet body.

[0016] The beneficial effects are as follows: 1. On the upper and lower positions on one side of the door panel body, quick-release connectors are detachably combined through mounting base parts. In this way, the door panel body can be detachably combined with the side part of the cabinet body by means of the coaxial cooperation between the upper and lower quick-release connectors and the upper and lower holes at the combined position of the side part of the cabinet body. At the same time, since the upper and lower quick-release connectors are symmetrically distributed, the door panel body can be smoothly combined with the combined position on the other side of the cabinet body by flipping the door panel body around the handle part for one week, realizing the function of the door panel body being installable with left-right interchangeability and improving the applicability of the door panel body;

[0017] 2. The door panel body is provided with a horizontal flanging part and a vertical flanging part to respectively correspond to the horizontal part and the vertical part of the corners at the combined position of the cabinet body. At the same time, a quick-release connector is detachably combined and fixed to the mounting base part of the vertical flanging part. In this way, the inner end of the rotating shaft body of the quick-release connector passes through the object-passing opening and then slides vertically downward along the mounting hole, and by means of the way of compressing the spring by the collar, the outer end of the rotating shaft body can smoothly move to be coaxially located below the inner end of the mating hole. At the same time, by means of the way of the spring releasing the compressed state, the outer end of the rotating shaft body can smoothly expose through the outer end of the mating hole. Then, by means of the way of the outer end of the rotating shaft body exposing through the outer end of the mating hole, it can be higher than the outer surface of the horizontal flanging part and smoothly be coaxially inserted and mated with the hole at the combined position of the cabinet body. The combination method of the door panel body and the cabinet body by means of the quick-release connector is simple and easy to achieve, facilitating the quick completion of the rotational connection of the door panel body at the combined position of the cabinet body by means of the quick-release connector;

[0018] 3. Only by pulling down the bottom end of the rotating shaft body can the outer end of the rotating shaft body be received inward to be lower than the outer end of the mating hole and separated from the hole at the combined position of the cabinet body. Then, by maintaining the pulled-down state of the rotating shaft body, the door panel body can be translated and detached from the combined position of the cabinet body. The disassembly method of the door panel body and the cabinet body by means of the quick-release connector is simple and easy to achieve, facilitating the subsequent quick separation of the door panel body and the cabinet body by means of the quick-release connector for maintenance and replacement;

[0019] 4. The mounting base part is specifically a mounting wing piece with only a fixed edge connected to the bottom edge of the bending opening. Then, by means of the way of the mounting wing piece being bent from the erected state to the flat state around the fixed edge, the quick setting of the mounting base part can be realized. At the same time, by means of the way of the mounting wing piece being bent from the flat state to the erected state around the fixed edge, the quick hiding of the mounting base part can be realized. The setting and hiding methods of the mounting base part are simple and easy to achieve, facilitating the quick machining of the mounting base part on the vertical flanging part, and then facilitating the smooth application of the vertical flanging part to the actual combination of the door panel body and the cabinet body.

[0030] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. All other implementation manners obtained by those of ordinary skill in the art without creative efforts based on the embodiments of the present invention belong to the scope protected by the present invention.

[0031] See Figures 1-7As shown in the figure, the utility model provides a cabinet with replaceable left and right door panels, which includes a door panel body 2. The door panel body 2 is vertically unfolded horizontally. Horizontally flanging parts 1 are horizontally arranged at the upper and lower edges in front of the door panel body 2, and vertically flanging parts 4 are vertically arranged at the two side edges in front of the door panel body 2. The orientations of the horizontally flanging parts 1 and the vertically flanging parts 4 respectively correspond to the horizontal part and the vertical part of the corner of the cabinet combination position. Specifically, the installation base parts 5 each include installation wing pieces 503 and bending openings 501. The edges of the installation wing pieces 503 at the upper and lower positions close to each other are fixed edges 502. Bending openings 501 are provided at the upper and lower positions of the vertically flanging parts 4. Only the fixed edge 502 of the installation wing piece 503 is fixedly connected to one side of the inner wall of the corresponding bending opening 501, and the installation wing pieces 503 are all horizontally arranged. The purpose of such a setting is that the installation base part 5 can be quickly set by bending the installation wing piece 503 around the fixed edge 502 from the vertical state to the horizontal state, and at the same time, the installation base part 5 can be quickly hidden by bending the installation wing piece 503 around the fixed edge 502 from the horizontal state to the vertical state. The setting and hiding method of the installation base part 5 are simple and easy to implement.

[0032] See Figures 1-3As shown, mounting base members 5 are combined and arranged at both the upper and lower positions of the vertical flanging portion 4. Quick-release connectors 3 are detachably fixed to the mounting base members 5. The outer parts of the upper and lower quick-release connectors 3 that are away from each other both extend out of the corresponding horizontal flanging portion 1, so as to support the lower part of the quick-release connector 3 through the mounting base member 5, and at the same time, the rotation connection of the door panel body 2 at the combined position of the cabinet body is completed through the quick-release connector 3. Specifically, each quick-release connector 3 includes a mounting hole 305, a mating hole 302, and a rotating shaft body 301. Mounting holes 305 are vertically formed at positions where the mounting wings 503 are close to the vertical flanging portion 4. Mating holes 302 are vertically formed at positions where the horizontal flanging portion 1 is close to the vertical flanging portion 4, and the mating hole 302 and the mounting hole 305 are vertically coaxially aligned. The upper and lower ends of the rotating shaft body 301 respectively coaxially pass through the corresponding mounting hole 305 and mating hole 302. Springs 303 are coaxially and clearance-fitted around the part of the rotating shaft body 301 between the corresponding horizontal flanging portion 1 and the mounting wings 503. Both ends of the springs 303 are fixed with collar rings 304. The collar rings 304 are sleeved around the corresponding rotating shaft body 301 in a coaxially sliding fit manner, and the upper and lower collar rings 304 respectively abut against the surfaces of the adjacent horizontal flanging portion 1 and the mounting wings 503. The function of such a setting is that the outer end of the rotating shaft body 301 can smoothly expose out of the outer end of the mating hole 302 by the spring 303 releasing the compressed state. Then, the outer end of the rotating shaft body 301 can be higher than the outer surface of the horizontal flanging portion 1 and smoothly inserted into and mated with the hole position at the combined position of the cabinet body by the way that the outer end of the rotating shaft body 301 exposes out of the outer end of the mating hole 302. The combination method of the door panel body 2 and the cabinet body with the quick-release connector 3 is simple and easy to achieve. Only by pulling down the bottom end of the rotating shaft body 301 can the outer end of the rotating shaft body 301 be retracted inside to be lower than the outer end of the mating hole 302 and separated from the hole position at the combined position of the cabinet body. Then, by keeping the rotating shaft body 301 in the pulled-down state, the door panel body 2 can be translated and detached from the combined position of the cabinet body. The disassembly method of the door panel body 2 and the cabinet body with the quick-release connector 3 is simple and easy to achieve.

[0033] See Figures 1-3As shown in the figure, the quick-release connector 3 and the door panel body 2 are optimized as follows. Specifically for the quick-release connector 3, the rotating shaft body 301 and the corresponding mounting holes 305 are in coaxial clearance fit, and the rotating shaft body 301 and the corresponding mating holes 302 are in coaxial sliding fit. With such a setting, it is convenient for there to be a certain clearance during the coaxial fit of the rotating shaft body 301 and the mounting hole 305. Subsequently, after the top end of the rotating shaft body 301 is lower than the mating hole 302, the rotating shaft body 301 can tilt in the mounting hole 305. In this way, it is not only convenient to obliquely insert the rotating shaft body 301 into the mounting hole 305 through the passing object opening 101 smoothly, but also convenient to detach the rotating shaft body 301 through the passing object opening 101 after tilting it later. Further optionally, the outer diameter of the collar 304 is larger than the aperture of the mounting hole 305 to ensure that the collar 304 cannot pass through the mounting hole 305. At the same time optionally, when the collar 304 abuts against the surface of the adjacent lateral flanging portion 1 and the surface of the mounting fin 503 respectively, the spring 303 is in a compressed state. With such a setting, it is convenient for the spring 303 to have a certain elastic force initially, and then it can press the collars 304 at the upper and lower positions against the bottom surface of the lateral flanging portion 1 and the top surface of the mounting fin 503 respectively.

[0034] Specifically for the door panel body 2, the lateral flanging portion 1 is provided with passing object openings 101 beside the rotating shaft body 301 to enable the rotating shaft body 301 and the collar 304 to pass through smoothly. Preferably, the passing object opening 101 is a circular opening and the aperture is at least twice the outer diameter of the collar 304 to facilitate obliquely inserting the rotating shaft body 301 into the mounting hole 305 through the passing object opening 101 smoothly. At the same time optionally, a handle portion 6 for convenient grasping is fixedly installed on the back surface of the door panel body 2 at the side away from the mounting fin 503. With such a setting, first, it is convenient to grasp the handle portion 6 to open and close the door panel body 2. At the same time, by rotating the door panel body 2 around the handle portion 6 for one week, the door panel body 2 can be smoothly combined at the side combination position on the other side of the cabinet body, realizing the function of the door panel body 2 being installable with left and right swapping.

[0035] With the above structure, specifically when the door panel body 2 is used in combination with the cabinet body, since quick-release connectors 3 are detachably combined with the mounting base parts 5 at the upper and lower positions on one side of the door panel body 2, the door panel body 2 can be detachably combined at the side position of the cabinet body by the coaxial matching of the quick-release connectors 3 at the upper and lower positions with the upper and lower holes at the combined position of the cabinet body edge respectively. At the same time, due to the symmetric distribution of the quick-release connectors 3 at the upper and lower positions, the door panel body 2 can be smoothly combined at the side combined position on the other side of the cabinet body by rotating the door panel body 2 one week around the axis of the handle part 6, realizing the function of the door panel body 2 being installable with left-right interchangeability, improving the applicability of the door panel body 2. Specifically, when the door panel body 2 is combined with and disassembled from the cabinet body, when combining, since the door panel body 2 is provided with a horizontal flanging part 1 and a vertical flanging part 4 to respectively correspond to the horizontal part and the vertical part of the corners at the combined position of the cabinet body, and the mounting base part 5 of the vertical flanging part 4 is detachably combined and fixed with a quick-release connector 3, the inner end of the rotating shaft body 301 of the quick-release connector 3 can pass through the object-passing opening 101 and then slide vertically downward along the mounting hole 305 and compress the spring 303 through the collar 304, enabling the outer end of the rotating shaft body 301 to smoothly move to a position coaxially below the inner end of the mating hole 302. At the same time, by releasing the compressed state of the spring 303, the outer end of the rotating shaft body 301 can smoothly expose through the outer end of the mating hole 302. Then, by the way that the outer end of the rotating shaft body 301 exposes through the outer end of the mating hole 302 and is higher than the outer surface of the horizontal flanging part 1, it can be coaxially inserted and mated with the hole at the combined position of the cabinet body. The combination method of the door panel body 2 and the cabinet body with the quick-release connector 3 is simple and easy to implement, facilitating the quick completion of the rotational connection of the door panel body 2 at the combined position of the cabinet body with the help of the quick-release connector 3. When disassembling, only by pulling down the bottom end of the rotating shaft body 301 can the outer end of the rotating shaft body 301 be received inside to a position lower than the outer end of the mating hole 302 and separated from the hole at the combined position of the cabinet body. Then, by maintaining the pulled-down state of the rotating shaft body 301, the door panel body 2 can be translated and detached from the combined position of the cabinet body. The disassembly method of the door panel body 2 and the cabinet body with the quick-release connector 3 is simple and easy to implement, facilitating the subsequent quick separation of the door panel body 2 and the cabinet body with the help of the quick-release connector 3 for maintenance and replacement. Specifically for the mounting base part 5, since the mounting base part 5 is specifically an installation wing 503 with only a fixed edge 502 connected to the bottom edge of the bending opening 501, the quick setting of the mounting base part 5 can be realized by bending the installation wing 503 around the fixed edge 502 from the erected state to the flat state. At the same time, the quick hiding of the mounting base part 5 can be realized by bending the installation wing 503 around the fixed edge 502 from the flat state to the erected state. The setting and hiding methods of the mounting base part 5 are simple and easy to implement, facilitating the quick machining of the mounting base part 5 on the vertical flanging part 4, and then facilitating the smooth application of the vertical flanging part 4 to the actual combination of the door panel body 2 and the cabinet body.

[0036] As described above, it is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the said claims.
