Description

Technical Field

[0001] The utility model relates to the technical field of bed accessories, in particular to a rectangular tube bed support accessory which is not easily deformed. Background Art

[0002] The bed stay is a bar in the bed frame used to support the bed board. Most of the two ends of the bed stay are clamped on the opposite side beams of the bed frame. Some are connected by bolts, but the operation is relatively complicated and the disassembly and assembly are inconvenient. As for the method of clamping with the bed frame, the clamping point between the bed stay and the bed frame will become loose after long-term use, which may easily cause the bed stay to fall off the bed frame, which not only affects the support of the bed board, but also poses a safety hazard of the bed stay hitting people for bunk beds.

[0003] For example, the patent document with application number CN202220230577.1 discloses a novel bed support accessory made of open profile. The novel bed support accessory made of open profile is provided with long slots on two opposite sides of the two ends of the rectangular tube bed support, so that the slots on both sides are inserted into the two side wing plates in the bed support installation groove of the fixing part, and the long slots and the wing plates are plugged together to ensure stable installation.

[0004] Looking through the comparative document, the applicant found the following problems: the bed board (the rectangular tube in this application) is still in an active state when assembled in the bed support. In other words, the bed board can be detached from the middle groove of the bed support, and the assembly stability is insufficient. This structure may cause the bed support to fall off and injure people in accidental circumstances, and the overall structural strength of the bed support is insufficient. On the one hand, the force-bearing area at the bottom of the groove is small, resulting in insufficient bearing capacity of the bed support. On the other hand, no support is set on both sides of the groove, which may cause abnormal noise caused by friction between metals.

[0005] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a rectangular tube bed support accessory that is not easy to deform is proposed. Utility Model Content

[0008] Furthermore, the bed support body includes a main board and a belly plate, and the belly plates are integrally fixed to the back surfaces of the upper and lower ends of the main board, and the main board and the integral belly plates at the upper and lower ends form a "J"-shaped structure.

[0009] Furthermore, the bed support body also includes an ear plate, and the ear plate is fixed to the end of the web facing away from the main board, and the ear plate is welded and fixed to the opening groove at the junction to achieve anti-deformation support for the crossbeam.

[0010] Furthermore, the bed support body also includes a notch, and an inwardly recessed notch is opened in the middle of the main board, and the opening size of the notch is smaller than the major diameter size of the rectangular tube, and the opening size of the notch is closely matched with the minor diameter size of the rectangular tube.

[0011] Furthermore, the bed support body also includes side wing plates and anti-slip patterns. Side wing plates are fixed on both sides of the groove, and anti-slip patterns are provided on the inner sides of the side wing plates.

[0012] Furthermore, the bed support body also includes a lower wing plate and a tongue, the lower wing plates are fixed on both sides of the bottom of the groove, and the tongue is fixed at the middle end of the bottom of the groove.

[0013] Furthermore, the bed support body also includes a spring sheet, and the front side of the latch tongue is provided with a spring sheet, and the spring sheet cooperates with the latch hole to realize locking of the rectangular tube.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. When the utility model is in use, firstly, the main body of the bed support of the present application is stamped and formed by 1.5mm thick high-quality cold-rolled steel plate. By welding the junction of the ear plate and the open groove to the inner side of the crossbeam, the crossbeam can be supported and prevented from deformation. Secondly, the side wing plates are added at both sides of the notch to increase its strength and make it less likely to deform, which can better limit the bed support and reduce the abnormal noise caused by the friction between the metals. The anti-slip grooves arranged on the inner sides of the side wing plates can compensate for the assembly shaking caused by the size deviation of the rectangular pipe fittings. Then, the lower wing plates are added on both sides of the bottom of the notch to increase the contact area with the stress-bearing part of the rectangular pipe fitting and increase its bearing capacity. Finally, a clamping tongue is added to the middle end of the bottom of the notch, which can be limited by cooperating with the clamping holes at both ends of the rectangular pipe fitting. In addition, a spring sheet is added to the front of the clamping to lock the position of the clamping hole, so that the rectangular pipe fitting cannot be detached from the notch after installation. In other words, once the bed board is placed in the bed support main body, it cannot be removed, which can completely prevent the bed support main body from falling off and injuring people in accidental circumstances.

DETAILED DESCRIPTION

[0020] The following is a further detailed description of the implementation of the present utility model in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0021] like Figures 1 to 3As shown in the figure, a rectangular tube bed support fitting that is not easily deformed includes a cross beam 1 and a bed support body 3. On the inner sides of the opposite faces of the two cross beams 1, there are opening grooves 2. The bed support body 3 is welded and fixed to one side of the opening groove 2. The bed support body 3 includes a main board 301 and a web 302. The web 302 is integrally fixed to the back of the upper and lower ends of the main board 301, and the main board 301 and the web 302 at the upper and lower ends form a "ji" - shaped structure. The bed support body 3 further includes an ear plate 303. The ear plate 303 is fixed to the end of the web 302 away from the main board 301, and the welded and fixed combination of the ear plate 303 and the opening groove 2 realizes the anti - deformation support for the cross beam 1. In this application, the bed support body 3 is formed by stamping a 1.5 - mm - thick high - quality cold - rolled steel plate. By welding the combination of the ear plate 303 and the opening groove 2 to the inner side of the cross beam 1, it can play a role in supporting and preventing the deformation of the cross beam 1. The bed support body 3 further includes a notch 304. An inward - recessed notch 304 is provided in the middle of the main board 301, and the opening size of the notch 304 is smaller than the large - diameter size of the rectangular pipe fitting 4, and the opening size of the notch 304 is closely matched with the small - diameter size of the rectangular pipe fitting 4. The bed support body 3 further includes side wing plates 305 and anti - slip patterns 306. The side wing plates 305 are fixed on both sides of the notch 304, and anti - slip patterns 306 are provided on the inner sides of the side wing plates 305. Adding side wing plates 305 on both sides of the notch 304 can enhance its strength, making it not easily deformed, better restricting the bed support, and reducing the abnormal noise caused by the friction between metals. The anti - slip patterns 306 provided on the inner sides of the side wing plates 305 can make up for the assembly shaking caused by the dimensional deviation of the rectangular pipe fitting 4. The bed support body 3 further includes lower wing plates 307 and a tongue 308. The lower wing plates 307 are fixed on both sides of the bottom of the notch 304, and the tongue 308 is fixed in the middle of the bottom of the notch 304. Adding lower wing plates 307 on both sides of the bottom of the notch 304 can increase the contact area with the stress area of the rectangular pipe fitting 4 and increase its bearing capacity. Finally, adding a tongue 308 in the middle of the bottom of the notch 304 can realize the limit through the cooperation with the locking holes 5 at both ends of the rectangular pipe fitting 4. The bed support body 3 further includes a spring piece 309. The spring piece 309 is provided on the front of the tongue 308, and the cooperation of the spring piece 309 and the locking hole 5 realizes the locking of the rectangular pipe fitting 4. Installing a spring piece 309 on the front of the latch can realize the locking of the position of the locking hole 5, so that the rectangular pipe fitting 4 cannot be detached from the notch 304 after installation. In other words, once the bed board is placed in the bed support body 3, it cannot be removed, which can completely avoid the accidental detachment of the bed support body 3 and injuring people. A rectangular pipe fitting 4 is inserted between the two cross beams 1, and locking holes 5 are provided at the inner bottom ends of the openings at both ends of the rectangular pipe fitting 4.

[0022] Working principle: When using this kind of rectangular tube bed support accessory that is not easy to deform, firstly, the bed support body 3 of the present application is stamped and formed by 1.5mm thick high-quality cold-rolled steel plate, and the joint of the ear plate 303 and the opening groove 2 is welded to the inner side of the beam 1, which can support the beam 1 and prevent deformation. Secondly, side wing plates 305 are added on both sides of the notch 304 to increase its strength and make it not easy to deform, which can better limit the bed support and reduce the abnormal noise caused by the friction between metals. The anti-slip pattern 306 arranged on the inner side of the side wing plate 305 can make up for the size deviation of the rectangular tube 4. The assembly shakes, and then, lower wing plates 307 are added on both sides of the bottom of the slot 304 to increase the contact area with the force-bearing part of the rectangular tube 4 and increase its bearing capacity. Finally, a latch tongue 308 is added to the middle end of the bottom of the slot 304, which can achieve limiting by cooperating with the latch holes 5 at both ends of the rectangular tube 4. In addition, a spring piece 309 is installed on the front of the latch to lock the position of the latch hole 5, so that the rectangular tube 4 cannot be detached from the slot 304 after the installation is completed. In other words, once the bed board is placed in the bed support body 3, it cannot be removed, which can completely prevent the bed support body 3 from falling off and injuring people in accidental circumstances.
