Description

Technical fields:

[0001] This utility model relates to the field of moxibustion bed technology, and specifically refers to a scissor-type lifting mechanism for moxibustion beds. Background technology:

[0002] Moxibustion, a traditional Chinese medicine therapy, uses the heat and medicinal properties of burning moxa wool to stimulate acupoints, achieving effects such as warming and unblocking meridians and regulating qi and blood. With the development of modern medical equipment, moxibustion beds have gradually become a solution to replace manual operation. Through motors and intelligent control, they can realize traditional medical techniques such as sparrow-pecking moxibustion and rotational moxibustion, reducing the labor intensity of medical staff and achieving the same moxibustion effect as traditional methods.

[0003] Because moxibustion produces a large amount of moxa oil and carbon black, these products adhere to the operating mechanism, causing damage over time. Existing products on the market often have complex operating mechanisms, with some having vertically installed lifting screws directly exposed in the upper space of the moxibustion chamber. These screws are prone to moxa oil buildup and, due to structural limitations, are difficult to disassemble and clean, leading to unstable operation and a high likelihood of malfunction.

[0004] For example, Chinese Patent Publication No. CN 221556762 U discloses a rotating and lifting moxibustion bed, which includes at least a moxibustion bed body and a matching hollow bed board, as well as a lifting and swinging mechanism inside the bed. The lifting and swinging mechanism achieves synchronous lifting and lowering of the moxibustion bed through a hexagonal rod and a lifting screw assembly. The smooth translation of the moxibustion bed is achieved by the cooperation of a disc driving a slider on the lifting and swinging mechanism and a slide rail on the moxibustion board. This utility model has a relatively simple structure, is relatively stable in actual use, has a low failure rate, and is easy to maintain. However, because the lifting and swinging mechanism is directly exposed in the upper space of the moxibustion chamber, moxa oil easily adheres to the lifting and swinging mechanism. Moreover, the lifting and swinging mechanism has a complex structure, is difficult to disassemble, and is not easy to clean. After use, the moxa oil adhering to the lifting and swinging mechanism can cause instability in the mechanism's operation and is prone to failure.

[0005] In view of the above, the inventors propose the following technical solution. Utility model content:

[0006] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a scissor-type lifting mechanism for moxibustion beds.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a scissor-type lifting mechanism for a moxibustion bed, comprising: at least one scissor leg hinged in the moxibustion chamber, a support platform module mounted on the scissor leg and raised and lowered with the movement of the scissor leg, a sliding frame slidably mounted in the moxibustion chamber for pushing the scissor leg to cross, and a driving device for driving the sliding frame to move the scissor leg. The upper and lower ends of one side of the scissor leg are fixed to the bottom of the support platform module and the bottom of the moxibustion chamber, respectively. The upper and lower ends of the other side of the scissor leg are slidably connected to the bottom of the support platform module and the bottom of the moxibustion chamber, respectively, and can move closer to and further away from the fixed ends. An ignition column cover plate is provided on the support platform module, covering the scissor leg, the sliding frame, and the driving device.

[0008] Furthermore, in the above technical solution, the bottom of the moxibustion chamber is provided with a sliding track for the movement of the lower movable part of the scissor foot, and the bottom of the support platform module is provided with an upper sliding track for the movement of the upper movable part of the scissor foot.

[0009] Furthermore, in the above technical solution, the lower movable part and the upper movable part of the scissor foot are respectively provided with a lower pulley and an upper pulley for moving in the lower slide and the upper slide.

[0010] Furthermore, in the above technical solution, the four scissor legs are arranged in a matrix, and the sliding frame is connected to the movable part at the lower end of the four scissor legs.

[0011] Furthermore, in the above technical solution, the driving device includes a lead screw assembly that passes through the sliding frame and a lifting motor for driving the lead screw assembly to move. The two scissor legs perpendicular to the direction of movement of the sliding frame are connected by a tie rod, which connects the hinge of the two scissor legs in series.

[0012] Furthermore, in the above technical solution, the bottom of the moxibustion chamber is provided with a mounting base plate for installing the scissor legs, sliding frame and driving device, and the mounting base plate is provided with a lower fixing seat for fixing the lower end of the scissor legs; the bottom of the support platform module is provided with an upper fixing seat for fixing the upper end of the scissor legs.

[0013] Furthermore, in the above technical solution, the support platform module includes a lower swing assembly installed on the upper end of the scissor legs, an upper swing assembly for installing the ignition column cover plate, multiple swing assemblies disposed between the lower swing assembly and the upper swing assembly, and a swing motor for driving the swing assemblies to move the upper swing assembly horizontally.

[0014] Furthermore, in the above technical solution, the swing upper component is provided with multiple ignition columns that pass through the ignition column cover plate.

[0015] After adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art: In this utility model, a driving device is used to drive the scissor legs to move, realizing the lifting and lowering of the support platform module. The structure is simple and compact, occupies little space, is easy to install, and operates reliably. Secondly, by setting an ignition column cover plate on the support platform module to prevent the moxa oil from contacting the moving mechanism, preliminary isolation and protection between the moxa oil and the moving parts are achieved. Furthermore, the ignition column cover plate is installed separately on the support platform module, making it easy to disassemble, maintain, and clean. Attached image description:

[0018] Figure 3 This is a schematic diagram of the linkage structure of the scissor legs in this utility model. Detailed implementation method:

[0019] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0020] See Figures 1 to 3 The diagram shows a scissor-type lifting mechanism specifically for moxibustion beds. It includes: at least one scissor leg 2 hinged within the moxibustion chamber 1; a support platform module 3 mounted on the scissor leg 2 and raised / lowered with its movement; a sliding frame 4 slidably mounted within the moxibustion chamber 1 to drive the scissor leg 2 in a crisscrossing motion; and a driving device 5 for driving the sliding frame 4 to move the scissor leg 2. The upper and lower ends of one side of the scissor leg 2 are fixed to the bottom of the support platform module 3 and the bottom of the moxibustion chamber 1, respectively. The upper and lower ends of the other side of the scissor leg 2 are slidably connected to the bottom of the support platform module 3 and the bottom of the moxibustion chamber 1, respectively, and can move closer to or further away from the fixed ends. An ignition column cover plate 6 is provided on the support platform module 3, covering the scissor leg 2, the sliding frame 4, and the driving device 5. The driving device 5 drives the scissor leg 2 to move, thereby raising and lowering the support platform module 3. The mechanism is simple and compact, occupies little space, is easy to install, and operates reliably. Secondly, by setting an ignition column cover plate 6 on the support platform module 3 to block the contact between the moxa oil and the moving mechanism, the initial isolation and protection between the moxa oil and the moving part is achieved. Moreover, the ignition column cover plate 6 is installed on the support platform module 3 in a split manner, which is easy to disassemble and convenient for maintenance and cleaning.

[0021] The bottom of the moxibustion chamber 1 is provided with a lower sliding track 10 for the movement of the lower movable part of the scissor legs 2, and the bottom of the support platform module 3 is provided with an upper sliding track 30 for the movement of the upper movable part of the scissor legs 2. The lower and upper movable parts of the scissor legs 2 are respectively provided with a lower sliding wheel 100 and an upper sliding wheel 300 for movement within the lower sliding track 10 and the upper sliding track 30. The movable connection between the lower sliding wheel 100 and the lower sliding track 10, and the upper sliding wheel 300 and the upper sliding track 30, makes the cross-movement of the scissor legs 2 smoother and more fluid, ensuring stable lifting and lowering of the support platform module 3. This smooth movement also reduces friction, which is more conducive to the operation of the drive module 5.

[0022] The four scissor legs 2 are arranged in a matrix, with the sliding frame 4 connected to the movable parts at the lower ends of the four scissor legs 2. Each scissor leg 2 includes two cross-fixed connecting rods, each with one fixed end and the other movable end. Specifically, in this embodiment: the lower end of one connecting rod is fixed to the moxibustion chamber 1, and the upper end of this connecting rod is fitted with an upper pulley 300, its movable limit being within the upper slide rail 30; the upper end of the other connecting rod is fixed to the bottom of the support platform module 3, and the lower end of this connecting rod is connected to the sliding frame 4 and fitted with a lower pulley 100, its movable limit being within the lower slide rail 10. The four scissor legs 2 work together to support the support platform module 3, and the sliding frame 4 connects the four scissor legs 2 for synchronized movement, resulting in greater support force for the support module 3 and smoother lifting and lowering motion.

[0023] The driving device 5 includes a lead screw assembly 51 that passes through the sliding frame 4 and a lifting motor 52 for driving the lead screw assembly 51 to move. Each pair of scissor legs 2 perpendicular to the direction of movement of the sliding frame 4 forms a group and is connected by a pull rod 20. That is, the two scissor legs 2 are respectively hinged to the two ends of the pull rod 20.

[0024] The bottom of the moxibustion chamber 1 is provided with a mounting base plate 11 for mounting the scissor legs 2, the sliding frame 4 and the driving device 5. The mounting base plate 11 is provided with a lower fixing seat 12 for fixing the lower end of the scissor legs 2. The bottom of the support platform module 3 is provided with an upper fixing seat 35 for fixing the upper end of the scissor legs 2.

[0025] The support platform module 3 includes a lower swing assembly 31 mounted on the upper end of the scissor legs 2, an upper swing assembly 32 for mounting the ignition column cover plate 6, multiple swing assemblies 33 disposed between the lower swing assembly 31 and the upper swing assembly 32, and a swing motor 34 for driving the swing assemblies 33 to move the upper swing assembly 32 horizontally. The swing motor 34 is connected to one of the swing assemblies 33, and the other swing assemblies 33 provide support and move with the upper swing assembly 32.

[0026] The swing upper component 32 is provided with multiple ignition columns 7 passing through the ignition column cover plate 6. The moxibustion chamber 1 is fixed to the bed frame of the moxibustion bed.

[0027] In summary, in this utility model, the ignition column 7 is installed on the crossbeam of the upper swing assembly 32, and a split ignition column cover plate 6 is placed on the upper swing assembly 32. The swing assembly 33 is installed on the lower swing assembly 31. The top of the scissor foot 2 is installed on the bottom surface of the lower swing assembly 31, and the bottom is fixed to the top surface of the mounting base plate 11. The mounting base plate 11 is fixed to the inner base plate of the moxibustion chamber 1 by four sets of rivet bolts, which are easy to disassemble and facilitate maintenance and cleaning. The lifting motor 52 is fixed on the mounting base plate 11 and drives the lead screw of the lead screw assembly 51 to rotate. The nut of the lead screw assembly 51 is fixed on the sliding frame 4, which drives the sliding frame 4 to move back and forth. The lead screw front support assembly 53 is movably installed on the lead screw front bracket 54 and supports the downward droop of the lead screw front end. Nuts are welded to both ends of the inner groove of the front and rear U-shaped beams of the sliding bracket 4 for installing the lower pulley 100. In this utility model, there are four sets of scissor feet 2, with two sets forming a group, which are respectively hinged to both ends of the pull rod 20. Each set of scissor legs 2 has a lower fixed seat 12, an upper fixed seat 35, a lower sliding track 10 and an upper sliding track 30. The upper fixed seat 35 and the upper sliding track 30 are fixed to the bottom surface of the main beam of the swing lower component 31, and the lower fixed seat 12 and the lower sliding track 10 are fixed to the mounting base plate 11.

[0028] During operation: The lifting motor 52 rotates, driving the lead screw assembly 51 to move the sliding frame 4 forward. The four sliding wheels 100 mounted on the sliding frame 4 move forward within the sliding track 10, thereby pulling the scissor legs 2. The movement of the hinged parts of the scissor legs 2 drives the lower swing assembly 31 to move downward. Similarly, when the lifting motor 52 reverses, the lower swing assembly 31 moves upward. This achieves the reciprocating lifting effect of the mechanism, simulating the effect of a sparrow pecking at food.

[0029] Of course, the above description is only a specific embodiment of the present utility model and is not intended to limit the scope of the present utility model. All equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model should be included in the scope of the claims of the present utility model.
