Description

Technical Field

[0001] The invention relates to a linkage mechanism for automatically lifting, lowering and flipping a medical top door, belonging to the technical field of medical equipment. Background Art

[0002] At present, the doors of medical equipment such as medical ultrasonic cleaning machines and medical boiling sterilizers widely used in hospitals generally adopt two door opening structures: manual flip doors and automatic lifting doors. The existing ultrasonic cleaning machines and boiling sterilizers with automatic lifting door structures rely on electric push rods to lift the top door for automatic lifting movement, but the top door remains in a horizontal state after being raised, resulting in the top door still blocking the operator's line of sight, creating obstacles for the operator to take and put instruments. The operator cannot clearly observe the full status of the instruments being taken and put inside the equipment, and there is a risk of instruments being missed due to falling inside the equipment. However, the ultrasonic cleaning machines and boiling sterilizers with manual flip door structures have a low degree of automation and are inconvenient to operate. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and propose a linkage mechanism for automatic lifting and flipping of a medical top door, which can realize two movements of automatic lifting and flipping of the top door, satisfying the operator's all-round observation of the instruments being taken and placed inside the equipment.

[0004] The linkage mechanism for automatic lifting and flipping of a medical top door described in the present invention comprises a lifting unit and a flipping unit, wherein the fixed end of the lifting unit is arranged on a frame, the moving end of the lifting unit is connected to a door bracket, and flipping units are respectively arranged on both sides of the door bracket, and the flipping unit comprises a support rod and a support rod guide rail, the support rod guide rail is arranged on the top of the door bracket, and the length direction of the support rod guide rail is along the horizontal direction of the top of the door bracket, the support rod guide rail is connected to one end of the support rod, and the other end of the support rod is connected to the middle part of the top door through a door shaft, the end of the support rod connected to the support rod guide rail is connected to one end of a steel wire rope, and the other end of the steel wire rope is connected to a counterweight block, and one end of the steel wire rope connected to the counterweight block sequentially passes through one and several limit stop bars that vertically support one side of the door bracket.

[0005] The support rod guide rail is connected to one end of the support rod, thereby limiting the linear movement of one end of the support rod along the support rod guide rail. When the top door is closed, the end of the support rod connected to the support rod guide rail is at the front end of the support rod guide rail, ensuring that the wire rope pulls the support rod along the support plate guide rail toward the rear of the top door when the lifting unit moves upward. The other end of the support rod is connected to the middle of the top door through the door shaft, so that the process of the top door flipping will drive the support rod to move along the support rod guide rail.

[0006] When in use, the lifting unit drives the door bracket, top door, support rod, support rod guide rail, wire rope and counterweight block to move upward, when the lifting unit moves upward until the counterweight block contacts the limit stop rod, the counterweight block can no longer move upward, and the lifting unit continues to move upward, and the wire rope pulls the support rod along the support plate guide rail toward the rear direction of the top door, thereby gradually increasing the angle between the support rod and the support rod guide rail in the length direction, and the support rod drives the top door to gradually flip upward, thereby increasing the angle between the top door and the door bracket, and when the lifting unit rises to the maximum stroke, the angle between the top door and the door bracket also increases to the maximum, and the top door's rising movement and flipping and opening movement end. When the lifting unit drives the door bracket, top door, support rod, support rod guide rail, wire rope and counterweight to move downward, the top door flips downward under the action of gravity. At the same time, the top door drives the support rod to move along the support rod guide rail toward the front of the top door until the top door is closed and in a horizontal state. The lifting unit continues to move downward, causing the counterweight to disengage from the limit stop rod and continue to move downward to the lowest point. The downward movement and flip closing movement of the top door end.

[0007] Preferably, the lifting unit comprises an electric push rod, the top of which is connected to the second vertical support in the middle of the door bracket, and the bottom of which is fixed to the frame. The electric push rod performs telescopic movement after being energized, thereby driving the door bracket and the top door to perform lifting movement.

[0008] Preferably, the lifting unit further comprises two linear slide rails, which are respectively arranged on the vertical supports 3 on both sides of the frame, and the linear slide rails are provided with two sliders used in conjunction with the linear slide rails, and the sliders are fixedly connected to the vertical support 1 of the door bracket. The sliders drive the door bracket to move up and down along the linear slide rails.

[0009] Preferably, a counterweight block slide is provided directly below the vertical support of the door bracket, the bottom of the counterweight block slide is fixed to the frame, two limit bars are fixed to the upper part of the inner cavity of the counterweight block slide, and the counterweight block is arranged in the inner cavity of the counterweight block slide below the limit bars. One end of the steel wire rope connected to the counterweight block passes between the two limit bars, and the counterweight block performs lifting movement in the inner cavity of the counterweight block slide.

[0010] Preferably, when the top door is in the closed state, the support rod and the support rod guide rail form an angle of 5° to 10° in the length direction, which is conducive to the rapid opening of the top door and reduces the travel of the support rod on the support rod guide rail when the top door moves from the closed state to the open state.

[0011] Preferably, the top door is connected to the rear of the door bracket via two door shafts, thereby increasing the stability of the top door in flipping motion centered on the door shafts.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The structural design of the present invention is reasonable. By setting a flip unit, the top door can be automatically flipped open, which satisfies the operator's all-round observation of the equipment being taken and placed inside the equipment; the automatic lifting and flipping movements of the top door are all realized by an electric push rod, which has a simple structure, is easy to operate, and saves equipment costs; linear slide rails are respectively arranged on both sides of the present invention, and two sliding blocks used in conjunction with the linear slide rails are arranged on the linear slide rails, which increase the stability of the lifting movement of the present invention and reduce noise.

[0019] The present invention will be further described below in conjunction with the accompanying drawings:

[0020] like Figure 1-Figure 4 As shown, the linkage mechanism for automatic lifting and flipping of the medical top door described in the present invention includes a lifting unit and a flipping unit, the fixed end of the lifting unit is arranged on the frame 15, the moving end of the lifting unit is connected to the door bracket 6, and the flipping units are respectively arranged on both sides of the door bracket 6, and the flipping unit includes a support rod 3 and a support rod guide rail 4, the support rod guide rail 4 is arranged on the top of the door bracket 6, and the length direction of the support rod guide rail 4 is along the horizontal direction of the top of the door bracket 6, the support rod guide rail 4 is connected to one end of the support rod 3, and the other end of the support rod 3 is connected to the middle part of the top door 5 through the door shaft 2, the end of the support rod 3 connected to the support rod guide rail 4 is connected to one end of the steel wire rope 16, the other end of the steel wire rope 16 is connected to the counterweight block 12, and the end of the steel wire rope 16 connected to the counterweight block 12 passes through a vertical support 8 on one side of the door bracket 6 and several limit bars 11 in sequence.

[0021] In this embodiment:

[0022] The lifting unit includes an electric push rod 14, the top of which is connected to the vertical support 1 in the middle of the door bracket 6, and the bottom of the electric push rod 14 is fixed on the frame 15. After the electric push rod 14 is powered on, it performs telescopic movement, thereby driving the door bracket 6 and the top door 5 to perform lifting movement.

[0023] The lifting unit further includes two linear slide rails 9, which are respectively arranged on the vertical supports 7 on both sides of the frame 15. The linear slide rails 9 are provided with two sliders 10 used in conjunction with the linear slide rails 9, and the sliders 10 are fixedly connected to the vertical supports 8 of the door bracket 6. The sliders 10 drive the door bracket 6 to move up and down along the linear slide rails 9.

[0024] A counterweight slide 13 is provided just below the vertical support 8 of the door bracket 6. The bottom of the counterweight slide 13 is fixed on the frame 15. Two limit bars 11 are fixed on the upper part of the inner cavity of the counterweight slide 13. The counterweight 12 is arranged in the inner cavity of the counterweight slide 13 below the limit bars 11. One end of the steel wire 16 connected to the counterweight 12 passes between the two limit bars 11, and the counterweight 12 moves up and down in the inner cavity of the counterweight slide 13.

[0025] When the top door 5 is in the closed state, the support rod 3 and the support rod guide rail 4 form an angle of 5° to 10° in the length direction, which is conducive to the rapid opening of the top door 5 and reduces the travel of the support rod 3 on the support rod guide rail 4 when the top door 5 is opened from the closed state.

[0026] The top door 5 is connected to the rear of the door bracket 6 through two door shafts 2, thereby increasing the stability of the top door 5 when performing a flipping motion centered on the door shafts 2.

[0027] In the specific working process, the electric push rod 14 extends after being energized, thereby the electric push rod 14 drives the door bracket 6, the top door 5, the support rod 3, the support rod guide rail 4, the wire rope 16 and the counterweight block 12 to move upward. When the electric push rod 14 extends and moves upward until the counterweight block 12 contacts with the limit stop rod 11, the counterweight block 12 cannot continue to move upward, and the electric push rod 14 continues to extend and move upward, and the wire rope 16 pulls the support rod 3 along the support plate guide rail toward the rear direction of the top door 5, thereby gradually increasing the length direction angle between the support rod 3 and the support rod guide rail 4, and the support rod 3 drives the top door 5 to gradually flip upward, thereby increasing the angle between the top door 5 and the door bracket 6. When the electric push rod 14 extends and rises to the maximum stroke, the angle between the top door 5 and the door bracket 6 also increases to the maximum, the rising movement and flipping and opening movement of the top door 5 end, the electric push rod 14 is powered off, and the top door 5 maintains the flipped open state.

[0028] When the electric push rod 14 is energized again and contracts to move downward, the electric push rod 14 drives the door bracket 6, the top door 5, the support rod 3, the support rod guide rail 4, the wire rope 16 and the counterweight 12 to move downward, and the top door 5 flips downward under the action of gravity. At the same time, the top door 5 drives the support rod 3 to move along the support rod guide rail 4 toward the front of the top door 5 until the top door 5 is closed and in a horizontal state. The electric push rod 14 contracts and continues to move downward, so that the counterweight 12 disengages from the limit stop rod 11 and continues to move downward to the lowest point. At the same time, the electric push rod 14 contracts to the minimum length, the downward movement and flipping and closing movement of the top door 5 end, the electric push rod 14 is powered off, and the top door 5 returns to the closed state.

[0029] The support rod guide rail 4 is connected to one end of the support rod 3, thereby limiting the linear movement of one end of the support rod 3 along the support rod guide rail 4. When the top door 5 is closed, the end of the support rod 3 connected to the support rod guide rail 4 is at the front end of the support rod guide rail 4, ensuring that the steel wire rope 16 pulls the support rod 3 along the support plate guide rail toward the rear of the top door 5 when the lifting unit moves upward. The other end of the support rod 3 is connected to the middle of the top door 5 through the door shaft 2, so that the process of the top door 5 doing the flipping movement will drive the support rod 3 to move along the support rod guide rail 4.
