Detailed ways

The structure of the present invention will be further described below in conjunction with the accompanying drawings and through embodiments. It should be noted that this embodiment is illustrative rather than limiting.

A concealed hinge device with positioning and support for an operating table, please refer to Figure 1-5d, the invention point is: the present invention provides a solution that integrates three mechanisms, and the concealed hinge device mainly includes a hinge assembly 1. Positioning component 2 and supporting component 3, see FIG. 1 .

The hinge assembly, referring to Fig. 2a-Fig. 2f, includes two parts of arc guide rail seat 1.1 and arc guide rail 1.2. The arc-shaped guide rail seat is composed of two parts: the seat plate 1.1.1 and the arc-shaped guide seat 1.1.2 arranged on the outside of the seat plate. There are screw holes on the seat plate. Through the installation screws and the upper box of the display console equipment 5 side walls are fixedly connected. An arc-shaped dovetail groove 1.1.3 structure is arranged in the middle of the arc-shaped guide seat to form a guide positioning groove. Described arc guide rail is made up of arc guide rail bar 1.2.1, roller stick 1.2.3, roller 1.2.4, roller block 1.2.5. The arc-shaped guide rail bar is composed of a circular arc-shaped arc-shaped guide rail bar main part 1.2.1a and an overhanging part 1.2.1b connected to the front end of the main part. The mounting screw is fixedly connected to the side wall of the console 4 of the display console equipment. The main part of the arc-shaped guide rail is designed as an arc-shaped structure concentric with the dovetail-shaped arc groove on the arc-shaped guide rail seat. A plurality of shaft holes are evenly distributed along the circumferential direction in the middle of the main part of the arc-shaped guide rail, and a roller roller is installed in each shaft hole. The roller roller is a combined structure of an inner shaft and an outer roller sleeve. The roller roller protrudes from the side close to the arc-shaped guide rail seat, and a roller is installed on the extended end of the roller roller, and is installed on the outer side of the roller There are roller gears fixed on the end of the inner shaft. The center line 1.2.2 of the arc guide rail where the centers of circles of the plurality of rollers installed on the arc guide rail bar is located is concentric with the dovetail arc groove on the arc guide rail seat. A plurality of rollers and roller gears are embedded in the dovetail-shaped arc groove, and the assembled rollers can roll in the arc-shaped guide rail seat. The outer arc portion of the arc-shaped guide rail is provided with two triangular slots, namely the first triangular slot 1.2.1d and the second triangular slot 1.2.1c. The first triangular locking slot is set at one end close to the overhanging part, and the second triangular locking slot is set at one end away from the overhanging part.

The first triangular slot is used to provide a place for the anti-drop lock tongue of the positioning component when the console is in a horizontal position, so as to avoid long-term stress on the spring of the support component in a horizontal position. The second triangular card slot is used for the reliable positioning of the operating table when it is raised about 80°, so as to avoid the sudden drop of the operating table under unexpected circumstances and cause injury to the user.

For the positioning components, please refer to Figure 3. Installed on the upper end of the upper box base of the display console, including the anti-drop lock seat 2.1, the anti-drop lock tongue 2.2, the anti-drop lock pressure handle 2.3, the spring 2.4, the bottom plate of the lock seat 2.5, and the first pin shaft (using ￠3 cylindrical pin) 2.6 , The second pin shaft (￠4 cylindrical pin) 2.7. The center of the anti-drop lock seat is provided with a deadbolt mounting hole, and on both sides of the deadbolt mounting hole, there are pressure handle piercing holes, and the pressure handle piercing holes on both sides are vertical long holes. The anti-drop lock tongue is installed in the lock tongue installation hole in a movable manner up and down. The top of the anti-fall lock tongue is designed with a triangular structure and protrudes from the upper end of the anti-fall lock seat to realize the outer circle of the arc-shaped guide rail. The two triangular card slots on the arc are matched respectively under the two working states. The middle part of the anti-drop deadbolt is designed with a rectangular inner cavity and a first pin hole running through the rectangular inner cavity, and the pin hole adopts an oblong hole structure. The anti-fall lock handle passes through the pressure handle piercing hole on the anti-fall lock seat and the rectangular inner cavity on the anti-fall lock tongue, and passes through the first pin installed in the middle part of the anti-fall lock handle and the first pin hole, Realize the connection of the anti-drop lock handle and the anti-drop deadbolt. The two ends of the anti-fall lock handle protrude from both sides of the anti-fall lock seat, one end of which is connected with the second pin hole arranged on the anti-fall lock seat through the second pin shaft, and this connection position constitutes the anti-fall lock handle The rotation center position, the other end of the anti-drop lock handle is the force application end. The bottom of the anti-drop deadbolt is designed with a cylindrical inner cavity, and a spring is installed in the cylindrical inner cavity. The lower end of the spring is pressed into contact with the upper end surface of the lock base base plate fixed on the lower end of the anti-drop lock base. By adopting the positioning component, the anti-drop lock tongue can be driven to move up and down by pressing the anti-drop lock handle.

The support assembly, please refer to Fig. 4, includes a support seat 3.3, a gas spring 3.2, and a connecting shaft 3.1. The lower end of the support seat is fixedly connected with the base of the upper box of the display console, one end of the connecting shaft is fixedly connected with the end surface of the operating table of the display console, and the gas spring is connected in the middle of the support seat and the connection shaft. Specifically, the cylinder rod end of the gas spring is hinged to the other end of the connecting shaft, and the cylinder barrel end of the gas spring is hinged to the upper end of the support seat. The stroke and supporting force of the gas spring are selected according to the weight and space of the console.

The upper box of the display console console is connected by the above hinge assembly, positioning assembly, and support assembly. As shown in Figure 5a, in the initial state, the console maintains a horizontal position, and the angle between the gas spring and the horizontal line is 5.5°. The elastic force of the spring is obliquely downward, and under the action of the spring force, the console maintains a horizontal position. At this time, the top triangular structure of the anti-drop bolt is inserted into the above-mentioned first triangular slot. When it needs to be flipped, lift the front of the console. When the gas spring exceeds the horizontal line, the console can be easily lifted under the support force of the gas spring. When the operating table is lifted about 80°, the gas spring reaches the maximum stroke. At this time, the anti-drop locking tongue of the positioning component is under the force of the spring, and the triangular structure falls into the second triangular slot of the arc-shaped guide rail. The operating table is reliable. locked, as shown in Figure 5b-5d. After assembly and maintenance, press down the anti-drop lock lever, the anti-drop lock lever will drive the anti-drop lock tongue to go down and disengage from the second triangular slot. At this time, press the front of the console to press the console to a horizontal state. With the supporting force of the gas spring, it can effectively avoid the rapid drop of the operating table due to the weight.

Although the embodiments and drawings of the present invention are disclosed for the purpose of illustration, those skilled in the art can understand that various replacements, transformations and modifications are possible without departing from the scope of the present invention and the spirit of the appended claims. Therefore, the scope of the present invention is not limited to what is disclosed in the embodiments and drawings.
