Description

Technical Field

[0001] The utility model relates to an armrest, in particular to an armrest used for various types of beds such as hospital beds and physiotherapy beds. Background Art

[0002] Early hospital beds did not have handrails on both sides of the bed, which made it extremely inconvenient for patients who had difficulty getting up or lying down on their own. They could only lie down or get up with the help of medical staff, family members, fellow patients or other people.

[0003] Later hospital beds were specially welded with handrails on both sides of the bed, so that patients who have difficulty getting up or lying down on their own can use the handrails to support themselves and get up or lie down without having to wait for help from others, which is much more convenient to use. However, this welded handrail is fixed and cannot be disassembled. Once assembled, it is fixed to the bed and difficult to disassemble, which limits the applicability of this type of bed. Although some handrails are currently detachable installation structures, they are less versatile and can often only meet the needs of one bed. Utility Model Content

[0023] like Figure 1-2 As shown, an armrest for a bed includes a supporting frame 1, one side of the supporting frame 1 is connected with at least two connecting clamps, and is installed and fixed to the bed frame through the connecting clamps, and the other side of the supporting frame is provided with a clamping member, the clamping member is connected to a fixing plate, the fixing plate is connected to an armrest frame 5, and the armrest frame and the supporting frame are arranged vertically.

[0024] The connecting clamp includes a clamping groove 2 and a clamping rod 3, one end of the clamping rod 3 is connected to the side wall of the clamping groove 2, and the other end of the clamping rod 3 is connected to the supporting frame 1. The clamping groove 2 is provided with a locking bolt 4, and the locking bolt 4 passes through the clamping groove 2 from top to bottom for locking. The clamping groove 2 is used to clamp the bed frame. The clamping groove 2 is a profile of a channel steel structure, the bed frame is clamped in it, and then the locking bolt 4 is locked, and the bed frame is clamped from the side. Two locking bolts are arranged on one clamping groove to ensure the clamping effect. The clamping groove is clamped from the side of the bed frame to achieve a stable assembly with the bed frame, and one end of the locking bolt is locked by a nut. The clamping rod is a square profile, and the clamping rod and the clamping groove can be welded, or it can be an integrally formed structure. The clamping rod and the supporting frame can be welded.

[0025] In this embodiment, a connecting clamp is installed at each end of the carrier frame 1, and the two sides jointly form a clamping force to ensure the stability of the assembly.

[0026] The clamping member includes a clamping groove 6 and a connecting rod 7, one end of the connecting rod 7 is connected to the clamping groove 6, and the other end of the connecting rod 7 is connected to the fixing plate 8. The clamping groove 6 clamps the carrier frame 1 therein, and the fastening bolt 9 is inserted from the clamping groove 6 and passed through the carrier frame 1 and then locked with a nut. The carrier frame can be quickly clamped by the clamping groove 6. When only one handrail frame is installed on a carrier frame, a corresponding clamping member can be assembled at this time. If two handrail frames need to be installed on a carrier frame, two clamping members can be assembled accordingly, and one clamping member is assembled correspondingly for one handrail frame.

[0027] The clamping groove 6 and the connecting rod 7 are an integrally formed structure, or the connecting rod is welded to the clamping groove.

[0028] A mounting plate 10 is provided at the lower part of the handrail frame 5, and the mounting plate 10 is locked and connected with the fixing plate 8 by mounting bolts 13.
