Description

Technical Field

[0001] The present invention relates to a concealed guide rail and locking mechanism for a bed, which is used to be installed on the bed frame of a special bed such as a massage bed, a medical bed, or a nursing bed, and supports a bracket on the upper portion of the bed so that the bracket can move or lock on both sides of the bed, thereby allowing working equipment installed on the bracket to move or remain stationary above the human body as needed. The present invention belongs to the field of mechanical manufacturing. Background Art

[0002] In daily life, special beds such as massage beds, medical beds, and nursing beds are very common. These beds often require the installation of some movable massage equipment, medical equipment, nursing equipment, etc. on top of them, such as the pneumatic massage therapy bed involved in patent 202120918316X. A common solution is to install guide rails and sliders on both sides of the bed, and then install the brackets of the supporting equipment. When locking is required, the locking fasteners are manually tightened. The disadvantage is that the guide rails protrude from the bed body, causing certain obstacles to getting in and out of bed, the lubricating oil of the guide rails can easily contaminate clothes and bedding, and the manual locking fasteners have low locking efficiency, cumbersome operation, and are not strong enough. The present invention provides a concealed guide rail and locking mechanism for massage beds, medical beds, nursing beds, etc., which are used to be installed on the bed frame to support the bracket on the bed frame, so that the bracket and the working equipment installed on the bracket can be moved or locked above the human body on the bed surface as needed, and the main components such as the guide rail, slider, and locking mechanism are hidden inside the bed frame, which does not affect the user's getting on and off the bed, does not allow the lubricating oil of the guide rail to contaminate clothes, and does not affect the aesthetic appearance of the bed. The electrified locking mechanism can also lock the bracket quickly and stably as needed. Summary of the Invention

[0003] To achieve the above-mentioned purpose, the technical solution adopted in the embodiment of the present invention is: a concealed guide rail and locking mechanism for a bed, which consists of a bed frame 2, a guide rail 6, a slider 7, a U-shaped support plate 4, a locking cylinder bracket 9, a locking cylinder 8, a locking pressure plate 10, a locking belt 11, etc. The bed frame 2 is installed on the bed legs 1, and the bed panel 3 is installed on the top of the bed frame 2. The cross-section of the left and right long sides of the bed frame 2 is approximately L-shaped. Fixed guide rails 6 are installed on the inner sides of the bottom edges of the left and right long sides of the bed frame 2, and locking belts 11 are installed in parallel with the guide rails 6. Each guide rail 6 has at least two sliders 7, and a certain distance is maintained between the two sliders 7 to ensure sufficient stability. The two U-shaped support plates 4 are respectively fixed to the guide rails 6 on the inner sides of the left and right sides of the bed frame 2 through the sliders 7, so that the two U-shaped support plates 4 can move back and forth on the guide rails 6. A part of the bottom of the U-shaped support plate 4 extends out of the bed frame 2 to connect to the fixed bracket 5. A hole is opened on the top of the U-shaped support plate 4 and a locking cylinder bracket 9 is installed. The locking cylinder 8 is fixed on the locking cylinder bracket 9. The locking pressure plate 10 is connected below the piston rod of the locking cylinder 8. The locking belt 11 is installed and fixed to the inner sides of the bottom edges of the left and right long sides of the bed frame 2, parallel to the guide rails 6. When locking, the locking cylinder 8 is inflated, and its piston rod pushes the locking plate 10 downward to compress the locking strap 11, preventing the two U-shaped support plates 4 from moving relative to the bed frame 2. When movement is required, the locking cylinder 8 is de-aired, and its piston rod moves upward to lift the locking plate 10 and disengage it from the locking strap 11. The lower portion of the U-shaped support plate 4, extending beyond the bed frame, has several openings for ventilation, pipe passage, and bolt installation. The locking cylinder 8 can also be replaced with a servo, electromagnet, or micromotor to drive the locking plate 10 downward to compress the locking strap 11.

[0004] The advantages of the embodiments of the present invention through the above technical solution are as follows: The above design provides a stable and reliable travel and locking mechanism for the upper equipment and brackets of special-purpose beds such as massage beds, nursing beds, and medical beds. The mechanism has the advantages of high strength, good rigidity, secure installation, high reliability, easy travel, stable locking, low failure rate, no staining of clothing, no impact on the aesthetics of the bed, and no interference with users getting in and out of bed. It can be widely used in special-purpose beds such as massage beds, medical beds, and nursing beds. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] During the specific production of the embodiment of the present invention, a bed frame 2 is made of sheet metal and mounted on bed legs 1. A bed panel 3 is mounted on the top of the bed frame 2. The left and right long sides of the bed frame 2 have a substantially L-shaped cross-section. Fixed guide rails 6 are mounted on the inner sides of the left and right bottom edges of the bed frame 2. Each guide rail 6 has at least two sliders 7. Two U-shaped pallets 4 are fixed to the guide rails 6 on the inner sides of the bed frame via the sliders 7, allowing the two U-shaped pallets 4 to move back and forth on the guide rails 6. The bottom of the U-shaped pallets extends out of the bed frame and connects to the fixed bracket 5. The top of the U-shaped pallets 4 has a hole and is mounted with a locking cylinder bracket 9. The locking cylinder 8 is fixed to the locking cylinder bracket 9. The piston rod of the locking cylinder 8 is connected to a locking pressure plate 10 below. A locking belt 11 is fixed to the inner sides of the left and right bottom edges of the bed frame 2, parallel to the guide rails 6. The bottom of the U-shaped pallets 4 extending out of the bed frame has several holes for ventilation, pipelines, and bolt fastening. The locking cylinder 8 can be replaced by a servo, electromagnet, or micromotor to drive the locking pressure plate downward to tighten the locking belt. After the above components are installed and tightened, the travel and locking parts are checked: when locking, the cylinder 8 is inflated, and the piston rod of the cylinder 8 moves downward to push the locking pressure plate 10 downward to tighten the locking belt 11, so that the two U-shaped support plates 4 cannot move. When movement is required, the cylinder 8 is exhausted, and the piston rod of the cylinder 8 moves upward to lift the locking pressure plate 10 and eliminate it from contact with the locking belt 11.
