Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel bed technology, specifically a steel bed with a magnetic positioning structure. Background Technology
[0002] A steel bed is a bedding frame with steel as the main load-bearing component, assembled by welding or bolting to form a rigid frame structure. The demand stems from the fact that steel has a higher strength-to-weight ratio than wood, and can bear greater loads without deformation. Metal tubing can achieve complex support structures through cold bending forming process, providing a stable sleeping platform. Surface coating treatment gives it moisture resistance and corrosion resistance, extending its service life. This product meets the comprehensive requirements of long-term durability, high space utilization, and cost control for industrial mass production.
[0003] Traditional steel bed frame assembly requires manual maintenance of the horizontal and vertical steel square tube end faces for bolt fastening. During operation, visual deviation or hand vibration can easily cause misalignment gaps in the connection surfaces. Furthermore, there is no temporary positioning mechanism when removing bolts, and components immediately separate and scatter under gravity. At the same time, due to the thin walls of the steel pipes in the traditional split branch structure, direct bolt fastening can easily lead to pipe wall compression deformation or thread stripping. Therefore, bolt connections are abandoned in favor of grooved lap joints, resulting in free movement gaps between the branch structure and the support structure. Under load, repeated collisions of components generate continuous noise that cannot be completely eliminated. Utility Model Content
[0004] The purpose of this invention is to provide a steel bed with a magnetic positioning structure to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A steel bed with a magnetic positioning structure includes two symmetrically arranged transverse steel square tubes. Support legs are welded to both sides of the bottom of each transverse steel square tube, and pads are fixedly installed at the bottom of each support leg. First iron blocks are embedded in both ends of each transverse steel square tube. Second iron blocks are attached to both sides of the transverse steel square tube and fixed with bolts. The second iron blocks are embedded in both ends of a longitudinal steel square tube and fixed with bolts. Magnetic pins are fixedly installed on the contact surfaces of the second iron blocks. When the transverse and longitudinal steel square tubes are in contact, the magnetic pins penetrate into the first iron blocks inside the transverse square tubes for magnetic fixation.
[0007] Preferably, a first diagonal brace is fixedly installed in the middle of the inner side of the longitudinal steel square tube, and a number of second diagonal braces are fixed at intervals on the inner side of the transverse steel square tube.
[0008] Preferably, a longitudinal branch pipe is attached to the top of the first diagonal brace, and a third iron block is embedded in both ends of the longitudinal branch pipe and fixed with bolts.
[0009] Preferably, the bottom end of the first diagonal brace is fixed by bolts that penetrate vertically upwards and extend into the third iron block inside the longitudinal branch pipe, and the top end of the longitudinal branch pipe is provided with several grooves at intervals.
[0010] Preferably, a transverse branch pipe is embedded in the groove, the transverse branch pipe is attached to the top of the second inclined support block, and a fourth iron block is embedded in both ends of the transverse branch pipe and fixed with bolts.
[0011] Preferably, the bottom end of the second diagonal brace is fixed by bolts that penetrate vertically upwards and extend into the fourth iron block inside the transverse branch pipe.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This steel bed with a magnetic positioning structure uses a magnetic pin fixed on the second iron block to penetrate the first iron block embedded in the transverse steel square tube, thereby achieving instantaneous adsorption and pre-positioning of the longitudinal and transverse steel square tubes, eliminating assembly gaps caused by manual alignment errors. At the same time, when removing bolts, the magnetic force continuously constrains the relative position of the components, avoiding the safety hazard of components falling off instantly.
[0014] 2. The steel bed with a magnetic positioning structure uses a fourth iron block embedded in the transverse branch pipe by a bolt at the bottom of the second diagonal support block that is vertically inserted and screwed into the bolt, and a third iron block embedded in the longitudinal branch pipe by a bolt at the bottom of the first diagonal support block that is vertically inserted and screwed into the bolt, so that the branch pipe system and the diagonal support block form a rigid connection with no displacement margin, thereby eliminating the noise source of component collision vibration.

Detailed Implementation
[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figures 1-4 As shown, this utility model provides a technical solution:
[0022] A steel bed with a magnetic positioning structure includes two symmetrically arranged transverse steel square tubes 101. Support legs 102 are welded to both sides of the bottom of each transverse steel square tube 101. Pads 103 are fixedly installed at the bottom of each support leg 102. First iron blocks 104 are embedded in both ends of each transverse steel square tube 101. Second iron blocks 105 are attached to both sides of the transverse steel square tube 101 and fixed with bolts. The second iron blocks 105 are embedded in both ends of a longitudinal steel square tube 106 and fixed with bolts. Magnetic pins 107 are fixedly installed on the contact surfaces of the second iron blocks 105. When the transverse steel square tube 101 and the longitudinal steel square tube 106 are in contact, the magnetic pins 107 penetrate into the first iron blocks 104 inside the transverse steel square tube for magnetic fixation.
[0023] The above scheme achieves vertical support for the bed by welding the outriggers to both sides of the bottom of the transverse steel square tube. The pads fixed to the bottom of the outriggers increase the contact area and prevent slippage. The first iron block embedded in both ends of the transverse steel square tube acts as the bolt bearing base. The second iron block embedded in both ends of the longitudinal steel square tube acts as the longitudinal connecting carrier. The bolts passing through the second iron block and the transverse steel square tube achieve rigid locking of the main frame. The magnetic pins fixed to the second iron block achieve the adsorption and pre-positioning of the first iron block. The magnetic pins passing through the first iron block achieve zero-gap fit between the transverse and longitudinal steel square tubes.
[0024] In this embodiment, preferably, a first diagonal brace 108 is fixedly installed in the middle of the inner side of the longitudinal steel square tube 106, and a plurality of second diagonal braces 109 are fixedly fixed at intervals on the inner side of the transverse steel square tube 101.
[0025] The above scheme achieves longitudinal structural reinforcement by fixing the first diagonal brace to the middle of the inner side of the longitudinal steel square tube, and achieves transverse structural deformation resistance by fixing the second diagonal brace at intervals to the inner side of the transverse steel square tube.
[0026] In this embodiment, preferably, the top end of the first diagonal brace 108 is fitted with a longitudinal branch pipe 110, and the two ends of the longitudinal branch pipe 110 are respectively embedded with a third iron block 111 and fixed with bolts.
[0027] The above scheme achieves the longitudinal support function by fitting the longitudinal branch pipe to the top of the first diagonal brace, reinforces the ends of the longitudinal branch pipe by embedding the third iron block into both ends of the longitudinal branch pipe, and achieves a stable connection between the longitudinal branch pipe and the main frame by bolts passing through the third iron block.
[0028] In this embodiment, preferably, the bottom end of the first diagonal brace 108 is fixed by bolts through and extending vertically upward into the third iron block 111 inside the longitudinal branch pipe 110, and the top end of the longitudinal branch pipe 110 is provided with a plurality of grooves 112 spaced apart.
[0029] The above scheme achieves the locking effect of the center force point of the longitudinal branch pipe by the bolt at the bottom end of the first diagonal brace block through to the third iron block, and achieves the positioning and clamping effect of the transverse branch pipe by the grooves spaced at the top of the longitudinal branch pipe.
[0030] In this embodiment, preferably, a transverse branch pipe 113 is embedded in the groove 112, the transverse branch pipe 113 is attached to the top of the second inclined support block 109, and a fourth iron block 114 is embedded in both ends of the transverse branch pipe 113 and fixed with bolts.
[0031] The above scheme achieves the overlapping of the grid-like support surface by embedding the horizontal branch pipe into the groove, the stress dispersion of the end of the horizontal branch pipe is achieved by embedding the fourth iron block into both ends of the horizontal branch pipe, and the horizontal branch pipe is quickly fixed by bolts passing through the fourth iron block.
[0032] In this embodiment, preferably, the bottom end of the second diagonal brace 109 is fixed by bolts that penetrate vertically upward and extend into the fourth iron block 114 inside the transverse branch pipe 113 using threads.
[0033] The above scheme achieves an indirect rigid connection between the transverse branch pipe and the transverse steel square pipe by means of the bolts at the bottom of the second diagonal brace block penetrating to the fourth iron block, and the transverse branch pipe wall resists deformation by means of the bolt screwing force borne by the fourth iron block.
[0034] In this embodiment, a steel bed employing a magnetic positioning structure is used by the operator who first erects two transverse steel square tubes 101 vertically via bottom-welded support legs 102. The pads 103 at the bottom of the support legs 102 ensure stable contact with the ground. When the transverse steel square tubes 101 are connected to the longitudinal steel square tubes 106, the second iron block 105 embedded at the end of the longitudinal steel square tube 106 and the first iron block 104 embedded at the end of the transverse steel square tube 101 approach each other. At this time, the magnetic pin 107 fixed to the second iron block 105 is magnetically attracted and actively penetrates into the first iron block 104 inside the transverse steel square tube 101, thus achieving connection between the longitudinal steel square tube 106 and the transverse steel square tube 101. The instantaneous and precise adsorption of tube 101; this magnetic pre-positioning ensures that the connection surfaces of the two are completely aligned without deviation, completely eliminating the assembly gap caused by manual alignment deviation when directly fixing steel pipes with bolts. This significantly improves assembly efficiency. Even when removing bolts for subsequent maintenance, the continuous adsorption force between the magnetic pin 107 and the first iron block 104 can maintain the temporary positioning of the frame, avoiding the safety risk of instantaneous disintegration and collapse of the components. Subsequently, the operator uses bolts to penetrate the second iron block 105 and the transverse steel square tube 101 to complete the rigid locking of the main frame. The first iron block 104 and the second iron block 105 provide a deep force-bearing base for the bolts, avoiding thread stripping or localization caused by the bolts being directly screwed onto the thin wall of the steel pipe. Deformation significantly improves the tensile strength of the connection nodes; after the main frame is assembled, the branch pipe system is installed. The top of the first diagonal brace 108, fixed inside the longitudinal steel square tube 106, fits against the longitudinal branch pipe 110. The bolt at the bottom of the first diagonal brace 108 extends vertically upwards into the third iron block 111 embedded in the longitudinal branch pipe 110 and is threaded and locked, forming the longitudinal support core; the third iron block 111 disperses the bolt stress to prevent the longitudinal branch pipe 110 wall from being deformed by pressure; at the same time, the groove 112 pre-set at the top of the longitudinal branch pipe 110 serves as a positioning reference, guiding the transverse branch pipe 113 to be accurately embedded into the inner cavity of the groove 112; the fourth iron block 114 embedded at both ends of each transverse branch pipe 113... The second diagonal brace 109 is located inside the transverse steel square tube 101. The bolt at the bottom of the second diagonal brace 109 is vertically screwed into the fourth iron block 114 through the tube wall to complete the fixation. The fourth iron block 114 transforms the traditional separate branch tube structure into an integral support system. The groove 112 is tightened with the limiting bolt of the transverse branch tube 113 to eliminate the noise hazard caused by the gap vibration of the traditional separate branch tube. When the bed is under load, the pressure of the transverse branch tube 113 is transmitted to the longitudinal branch tube 110 through the groove 112, and then transmitted from the longitudinal branch tube 110 to the first diagonal brace 108 through the third iron block 111. Finally, the pressure is distributed to the thick area of the side wall of the longitudinal steel square tube 106 by the first diagonal brace 108.Similarly, the pressure at both ends of the transverse branch pipe 113 is transmitted to the second diagonal brace 109 through the fourth iron block 114, and then dispersed into the box-shaped structure of the transverse steel square tube 101. In this process, the first diagonal brace 108 and the second diagonal brace 109 play the role of transmission hub, so that the stress is evenly distributed along the main structure, effectively preventing deformation and abnormal noise caused by local stress concentration. The magnetic pre-positioning of the main frame and the bolt combination of the first iron block 104 and the second iron block 105 provide an initial zero-gap connection. The combination of the third iron block 111, the fourth iron block 114 and the diagonal brace of the branch pipe system continuously suppresses the vibration during use. The dual mechanism works together to ensure that the steel bed remains quiet and stable under long-term load. Finally, the transverse branch pipe 113 and the longitudinal branch pipe 110 form a gridded support surface under the synergistic constraint of the first iron block 104, the second iron block 105, the third iron block 111, the fourth iron block 114 and the diagonal brace, achieving an integrated breakthrough in assembly efficiency, connection reliability and quiet use.
