Description
Technical Field
[0001] The utility model relates to the technical field of daily beds, in particular to an installation structure of bed corner brackets. Background Art
[0002] Bed frames are used in many occasions. For example, dormitories often use two-layer bed frames. The main structure of the bed frame is a frame structure composed of four columns and four beams connecting the four columns horizontally and vertically. The four beams are in the same horizontal plane. For the convenience of assembly and transportation, the connection between the beams and the columns is usually detachable. In order to make the frame structure more stable, corner brackets are installed at the four connecting corners, as shown in the attached figure. Figure 1 As shown, through holes are opened on the two sides of the angle bracket iron, and bolts are usually used to connect the crossbeams during installation. The disadvantages of this connection are that the bolts are easy to loosen after the bed frame is shaken for a long time, and on the other hand, the connection between the angle bracket iron and the two crossbeams is easy to leave a gap, making the frame structure unstable and prone to noise during use. Summary of the invention
[0003] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide an installation structure for bed foot angle brackets which has a simple structure, is easy to assemble and disassemble, and can achieve a tight connection.
[0004] The utility model achieves the above purpose in the following way:
[0005] The utility model discloses a mounting structure for a bed corner bracket iron, comprising a column, a crossbeam transversely connected to both sides of the column and a corner bracket iron clamped with the crossbeam, wherein clamping plates are arranged on both sides of the corner bracket iron, and a clamping hole longitudinally plugged with the clamping plate is arranged on the crossbeam.
[0006] Furthermore, a rib is protruded longitudinally from the upper portion of the clamping plate, and the clamping hole is a bridge-shaped through hole fixedly arranged on the inner side of the crossbeam.
[0007] Furthermore, the column is a profile with a right-angle V-shaped cross-section, and a stopper is provided on the inner side of the clamping plate, and the outer side of the stopper presses against the interface between the column and the beam.
[0008] Furthermore, the end of the rib is provided with a gradually thickened wedge-shaped surface.
[0009] Furthermore, there are two clamping holes, one at the top and the other at the bottom.
[0010] Furthermore, the angle code iron is formed by bending a thin plate, and the ribs are formed by reverse stamping.
[0011] Furthermore, the ribs on the two side clamps are connected as one.
[0012] Furthermore, a gap is provided between the clamping plate and the abutment plate.
[0013] The beneficial effects of the utility model: the utility model provides an installation structure for bed corner brackets, comprising a column, a beam transversely connected to both sides of the column and a corner bracket clamped to the beam, a clamping plate is arranged on both sides of the corner bracket, and a clamping hole is arranged on the beam which is longitudinally plugged into the clamping plate. Two crossbeams are clamped on both sides of the column. The upper plane of the angle bracket iron is triangular, and the two side edges are bent and extended downward. The corners of the angle bracket iron point to the column, and the two clamping plates are close to the outside of the angle bracket iron. Clamping holes are opened on the inner sides of the two crossbeams. After the clamping plates on both sides are clamped into the clamping holes from top to bottom, the two clamping plates tighten and fix the distance between the two crossbeams, and the two side edges of the angle bracket iron are respectively pressed against the two crossbeams. Since the clamping plates clamp the clamping holes from top to bottom, the connection between the column and the two crossbeams is more secure. When such angle bracket irons are installed on the four corners of the bed, the four angle bracket irons restrain each other, making the bed more stable, and will not loosen or generate noise even after long-term use and shaking. Moreover, this clamping method does not require fasteners such as bolts, and is simple and convenient to disassemble and assemble. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] refer to Figures 2 to 6 As shown, a mounting structure of a bed corner rail is shown, comprising a column 1, a beam 2 transversely connected to both sides of the column 1, and a corner rail 3 clamped with the beam 2, wherein clamping plates 31 are provided on both sides of the corner rail 3, and a clamping hole 21 is provided on the beam 2 for longitudinally plugging with the clamping plate 31.
[0023] As shown in the accompanying drawings, two cross beams 2 are clamped on both sides of the column 1, and the upper plane of the corner code iron 3 is triangular, with two side edges bent and extended downward, and the corners of the corner code iron 3 point to the column 1, and the two clamping plates 31 are close to the outer side of the corner code iron 3, and the inner sides of the two cross beams 2 are provided with clamping holes 21. After the corner code iron 3 clamps the clamping plates 31 on both sides into the clamping holes 21 from top to bottom, the two clamping plates 31 tighten and fix the distance between the two cross beams 2, and the two side edges of the corner code iron 3 are respectively pressed against the two cross beams 2. Since the clamping plates 31 clamp the clamping holes 21 from top to bottom, the connection between the column 1 and the two cross beams 2 is more secure. When such corner code irons 3 are installed on the four corners of the bed, the four corner code irons 3 restrain each other, making the bed more stable, and will not loosen or generate noise even after long-term use and shaking. Moreover, this clamping method does not require fasteners such as bolts, and is simple and convenient to disassemble and assemble.
[0024] Furthermore, a rib 32 is protruded longitudinally from the upper portion of the clamping plate 31 , and the clamping hole 21 is a bridge-shaped through hole fixedly provided on the inner side of the crossbeam 2 .
[0025] As shown in the accompanying drawings, the through-type clamping hole 21 can be formed by a U-shaped plate fixed on the crossbeam 2 by welding or riveting, or can be made of the crossbeam 2 itself. Usually, the crossbeam 2 is a hollow tube profile. By punching a bridge-shaped plate on the inner side of the crossbeam 2, a through-type clamping hole 21 can also be formed, which saves more materials and simplifies the process. The clamping plate 31 is divided into two parts, the ribs 32 are only in the upper half, and the ribs 32 increase the thickness of the clamping plate 31 and increase the strength. Since the wall of the clamping hole 21 is a thin plate, it has a certain elasticity. When the clamping hole 21 is installed, the thinner lower half of the clamping plate 31 is easier to be clamped into the clamping hole 21. When the angle code iron 3 is pressed downward, the ribs 32 also enter the clamping hole 21 and press the inner wall of the clamping hole 21. Under the joint action of the ribs 32 on the two clamping plates 31, the gap that may exist between the angle code iron 3 and the two clamping holes 21 can be effectively eliminated, so that the angle code iron 3 and the crossbeams 2 on both sides can be reliably and tightly connected.
[0026] Furthermore, the column 1 is a profile with a right-angle V-shaped cross section, and a butt plate 33 is further provided on the inner side of the clamping plate 31 , and the outer side of the butt plate 33 presses against the interface between the column 1 and the beam 2 .
[0027] As shown in the accompanying drawings, there is a certain distance between the two side walls of the column 1 and the right-angled inner corner of the column 1, and the two cross beams 2 are respectively clamped with the two side walls of the right-angled column 1. The clamping plate 31 on the angle code iron 3 is on the outside away from the right-angled inner corner and is longer, and the abutment plate 33 is on the inside close to the right-angled inner corner, located at the interface between the column 1 and the cross beam 2 and is shorter. After the clamping plate 31 clamps the clamping hole 21, the angle code iron 3 is subjected to tensile stress between the force points of the two clamping plates 31, so that the outer side wall of the abutment plate 33 is pressed against the interface, thereby eliminating the lateral gap that may exist in the clamping of the column 1 and the cross beam 2, and making the interface smooth. Under the joint action of the two sets of clamping plates 31 and the abutment plate 33, the column 1, the two cross beams 2 and the angle code iron 3 are connected into a tight whole. The abutment plate 33 with a shorter length has better strength and can withstand a greater clamping force.
[0028] Furthermore, the end of the rib 32 is provided with a gradually thickened wedge-shaped surface 321 .
[0029] As attached Figure 6 As shown, the wedge-shaped surface 321 has a certain slope, so that the rib 32 can gradually press against the inner wall of the clamping hole 21 during the process of being inserted into the clamping hole 21.
[0030] Furthermore, the clamping holes 21 are provided in two upper and lower positions.
[0031] As shown in the accompanying drawings, the upper and lower clamping holes 21 are coaxial holes. After the clamping plate 31 passes through the upper clamping hole 21, its end passes through the lower clamping hole 21. The clamping plate 31 is more stable through the limiting of the upper and lower clamping holes 21 to prevent swinging under the action of external force.
[0032] Furthermore, the angle iron 3 is formed by bending a thin plate, and the rib 32 is formed by reverse stamping.
[0033] As attached Figure 3 As shown, the thin plate has good elasticity, and the punching of the outer contour and the ribs 32 and the bending forming can be completed at one time, and the processing is simple and convenient.
[0034] Furthermore, the ribs 32 on the two side clamping plates 31 are connected as one.
[0035] As shown in the drawings, the integrally connected ribs 32 are easier to position during punching and can increase the overall strength of the angle bracket 3.
[0036] Furthermore, a gap 34 is provided between the clamping plate 31 and the abutting plate 33 .
[0037] As shown in the drawings, the gap 34 can ensure that the rest of the clamping plate 31 will not touch the flange of the clamping hole 21 when the clamping plate 31 is clamped into the clamping hole 21, and can also ensure that the clamping plate 31 and the abutting plate 33 can each complete the stretching and abutting functions.
