Description

Technical Field

[0001] The utility model relates to the field of bed frame structures, in particular to a bed frame with a stable structure. Background Art

[0002] The combined bed frame structure currently on the market is usually composed of four frames on the front, back, left and right sides to form the overall frame of the bed frame, and then a number of cross beams are arranged and fixed between the left and right frames to form a complete bed frame structure.

[0003] In the prior art, the fixing method of the crossbeam is generally as recorded in the lower bed frame of the double-layer iron bed disclosed in application number 202221206765.7, where the inner side of the cross bar (equivalent to the crossbeam) is provided with an installation structure of a socket that is buckled with the longitudinal bed beam, that is, the frame fixing sockets on the left and right sides, and the two ends of the crossbeam are directly buckled into the sockets of the left and right frames respectively.

[0004] Although this type of structure can support the beam, it cannot fix the beam. The beam will still move relative to the frame on the left and right sides, and a stable structure cannot be formed. Utility Model Content

[0005] In view of the deficiencies of the above background technology, the utility model provides a bed frame with a stable structure.

[0006] The utility model adopts the following technical solutions:

[0007] A bed frame with a stable structure, the bed frame comprising:

[0008] Two side frames are provided correspondingly, and a row of clamping parts are fixed on the corresponding sides of the two side frames, the clamping parts are U-shaped, and a raised first guide part is provided on the bottom surface of the clamping parts, and the first guide part is inclined upward in the direction between the two side frames;

[0009] Two corresponding end frames are respectively arranged on both sides between the two side frames, and both sides of the end frames are respectively detachably connected to the two side frames;

[0010] A plurality of cross beams connecting the two side frames, each of the two correspondingly arranged clamping members is connected to one of the cross beams, and the bottom surfaces of the cross beams near both ends are provided with first mounting holes;

[0011] Wherein, the two ends of the cross beam are respectively embedded in the two clamping parts corresponding to the two side frames from top to bottom, and the sides of the two first mounting holes close to the end of the cross beam are respectively clamped on the upward inclined surfaces of the two first guide parts.

[0012] In a possible implementation, the bed frame further includes a support frame arranged between the two side frames, two ends of the support frame are respectively connected to the two end frames, and each of the cross beams rests on the support frame.

[0013] In a possible implementation, a second guide portion is provided on a corresponding surface of the two end frames, the second guide portion is inclined upward in the direction between the two end frames, and the second guide portion is a conical sheet structure with a small top and a large bottom. Second mounting holes are provided on the end surfaces at both ends of the support frame, and the second mounting holes are conical holes with a large top and a small bottom; the second mounting holes at both ends of the support frame are respectively inserted into the outside of the second guide portions of the two end frames from top to bottom, and the two sides of the two second mounting holes are respectively stuck outside the two sides of the second guide portions.

[0014] In a possible implementation, threaded holes are provided at both ends of the side frame, and the threaded holes are adapted for spiral connecting bolts. Penetrating connecting holes are provided at both ends of the end frame, and the connecting holes at both ends of the end frame respectively correspond to the threaded holes of the side frames. After the bolts pass through the connecting holes, they are spirally connected to the threaded holes to press the end frame toward the side frame.

[0015] From the above description of the structure of the utility model, it can be seen that compared with the prior art, the utility model has the following advantages: when installing the utility model, it is only necessary to fix the two ends of the two end frames to the two side frames respectively by screwing in bolts, and then successively insert the two ends of the beams into the clamping parts of the two side frames by directly pressing down, and the first mounting hole is sleeved outside the first guide part, and then the beam is continued to be pressed down. The first mounting hole can be used to clamp the first guide part tighter downward by utilizing the inclination of the back side of the first guide part, and at the same time, the two side frames can be pulled tighter to the middle of the beam, avoiding the movement of the beam relative to the two side frames, which is beneficial to improving the firmness of the beam connecting the two side frames, thereby improving the stability of the overall structure of the bed frame.

[0028] In addition, in the present application, directional terms such as "upper" and "lower" are defined relative to the orientation of the components in the drawings. It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they may change accordingly according to the changes in the orientation of the components in the drawings.

[0029] The utility model discloses a bed frame with a stable structure. Figure 1 and 3 As shown, the bed frame includes a side frame 1, an end frame 2, a cross beam 3 and a support frame 4, specifically including two correspondingly arranged side frames 1 and two correspondingly arranged end frames 2 and a plurality of cross beams 3 connecting the two side frames 1, and a support frame 4 is also arranged between the two side frames 1. Among them, the two end frames 2 are respectively arranged at the two ends between the two side frames 1, and the two ends of the support frame 4 are respectively connected to the two end frames 2, so that the support frame 4 can support the middle position of each cross beam 3 to avoid the middle of the cross beam 3 from collapsing, so that the bed frame can effectively support the bed board and the mattress.

[0030] The structure of the detachable connection between the end frame 2 and the side frame 1 can be as shown in the attached Figure 2As shown, threaded holes are provided on the sides of both ends of the side frame 1, and the threaded holes are adapted to the spiral connection bolts 5. Both ends of the end frame 2 are provided with penetrating connection holes. When installing, the end frame 2 is placed between the ends of the two side frames 1, and the connection holes at both ends of the end frame 2 are respectively matched with the threaded holes of the two side frames 1, and then the bolts 5 are passed through the connection holes and screwed to the threaded holes for tightening, so that the bolts 5 press the end frame 2 to the side frame 1 to achieve the installation and fixation of the end frame 2 and the side frame 1. In addition, when disassembling, the bolts 5 can be screwed out.

[0031] As attached Figure 4 As shown, the two end frames 2 are provided with second guide portions 21 on the corresponding sides, the second guide portions 21 are inclined upwards in the direction between the two end frames 2, and the second guide portions 21 are in a tapered sheet structure with a small top and a large bottom. The second guide portions 21 can be provided on the end frames 2 by welding. Figure 5 The end surfaces of both ends of the support frame 4 are provided with second mounting holes 401, and the second mounting holes 401 are tapered holes with a larger top and a smaller bottom. Figure 3 , 9 As shown in Figure 10, the support frame 4 is inserted between the two end frames 2 from top to bottom, so that the second mounting holes 401 at the two ends of the support frame 4 are respectively sleeved on the outside of the second guide parts 21 of the two end frames 2 from top to bottom, and the two sides of the two second mounting holes 401 are respectively clamped on the outside of the two sides of the second guide parts 21, so as to realize the connection and fixation between the two ends of the support frame 4 and the two end frames 2. Since the second mounting holes 401 are tapered holes with a larger top and a smaller bottom, and the second guide parts 21 are tapered sheet structures with a smaller top and a larger bottom, the support frame 4 is continuously pressed down, so that the second mounting holes 401 clamp the second guide parts 21 more tightly, and the two end frames 2 can be pulled closer to the middle of the support frame 4, which is conducive to improving the firmness of the connection between the support frame 4 and the two end frames 2.

[0032] Continue to refer to the attached Figure 4 A row of clamping members 11 are fixed on the corresponding side of the two side frames 1, and each of the two corresponding clamping members 11 is connected to a crossbeam 3, and its connection structure can be as shown in the attached Figure 6 and 7 As shown, the bottom surface of the cross beam 3 near both ends is provided with a first mounting hole 301, the clamping member 11 is U-shaped, and the bottom surface of the clamping member 11 is provided with a protruding first guide portion 111, and the first guide portion 111 is inclined upward in the direction between the two side frames 1. Preferably, the first guide portion 111 can be a bent portion formed by stamping upward on the bottom surface of the clamping member 11. When installing the cross beam 3, as shown in the attached Figure 8As shown, the two ends of the crossbeam 3 are respectively embedded in the two clamping pieces 11 corresponding to the two side frames 1 from top to bottom, and the sides of the two first mounting holes 301 close to the ends of the crossbeam 3 are respectively clamped on the upward inclined surfaces of the two first guide parts 111. Through the connection of this structure, the ends of the crossbeam 3 and the clamping pieces 11 can be connected, thereby achieving the connection and fixation of the ends of the crossbeam 3 and the side frames 1. Furthermore, when the crossbeam 3 is further pressed down, the first mounting hole 301 can be used to clamp the first guide part 111 downward more tightly by utilizing the inclination of the back of the first guide part 111, and at the same time, the two side frames 1 can be pulled tighter toward the middle of the crossbeam 3, which is conducive to improving the firmness of the connection between the crossbeam 3 and the two side frames 1, thereby improving the stability of the overall structure of the bed frame.

[0033] After adopting the above structure, the process of installing the bed frame of the utility model is as follows:

[0034] s1: Place two side frames 1 in parallel, and then place two end frames 2 between the two side frames 1 respectively. Then, in the four diagonal corners of the frame formed by the side frames 1 and the end frames 2, the connection holes of the end frames 2 correspond to the threaded holes of the side frames 1. Then, bolts 5 are passed through the connection holes and screwed to the threaded holes, so that the two side frames 1 and the two end frames 2 are fixed to form a frame.

[0035] s2: Insert the support frame 4 from top to bottom between the two end frames 2, so that the second mounting holes 401 at the two ends of the support frame 4 are respectively stuck outside the second guide parts 21 on the side surfaces of the two end frames 2, and press downward to make the support frame 4 tighten and fix the two end frames 2 at the two ends of the support frame 4;

[0036] s3: Place each crossbeam 3 between the two side frames 1 in turn, and insert the two ends of each crossbeam 3 into the corresponding two clamping parts 11 respectively, so that the two first mounting holes 301 at the bottom of the crossbeam 3 are respectively clamped on the upward inclined surfaces of the first guide parts 111 at the bottom of the two clamping parts 11, and then continue to press the crossbeam 3 downward so that the first mounting holes 301 clamp the first guide parts 111 tighter downward, and at the same time, the two side frames 1 can be pulled tighter toward the middle of the crossbeam 3, so that the crossbeam 3 tightens and fixes the two side frames 1 at the two ends of the crossbeam 3.

[0037] As can be seen from the above installation method, the utility model can split the bed frame into several parts such as the side frame 1, the end frame 2, the support frame 4 and the crossbeam 3, which is convenient for packaging and transportation. During installation, only the two ends of the two end frames 2 need to be fixed to the two side frames 1 by screwing in the bolts 5, and then the support frame 4 is fixed to the two end frames 2 by directly pressing down, and finally, each crossbeam 3 is sequentially connected and fixed to the two ends of the crossbeam 3 by directly pressing down, so that the two ends of the crossbeam 3 can be connected and fixed to the clamping parts 11 of the two side frames 1, thereby completing the installation of the utility model. And later, as the bed frame is used, the crossbeam 3 and the support frame can be continuously pressed down by the downward pressure formed by people lying on the bed, so that the side of the first mounting hole 301 of the crossbeam 3 can be continuously pressed against the second guide part 21 to pull the side frame 1 tighter, and the second mounting hole 401 of the support frame 4 can clamp the second guide part 21 tighter and pull the end frame 2 tighter. It can be seen that the structure of the utility model is more conducive to improving the firmness and stability of the overall structure of the bed frame as the use time increases.

[0038] The above is only a specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any non-substantial changes to the utility model using this concept shall be deemed as an infringement of the protection scope of the utility model.
