Description

Technical Field

[0001] This utility model relates to the technical field of moxibustion fixing devices, specifically to a clamp for moxibustion installation and fixing. Background Technology

[0002] Moxibustion, a traditional Chinese medicine external therapy, utilizes the heat and medicinal components generated by burning moxa sticks to act on acupoints on the human body. It has wide applications in regulating sub-health conditions and treating chronic diseases. With the popularization of moxibustion therapy, the safety, stability, and convenience of moxibustion devices have become core concerns for the industry's development. Among these, the installation and fixing structure of the moxa sticks directly affects the treatment effect and user experience.

[0003] Currently, the moxibustion fixation devices used in intelligent moxibustion robots still have many technical pain points in practical applications: Firstly, there is insufficient stability. Traditional moxibustion devices often rely on Velcro fastening, elastic cord wrapping, or simple plug-in structures. When the patient moves slightly, the moxa stick is prone to circumferential rotation or axial displacement. This not only causes the heat from the moxa stick to deviate from the target acupoint, reducing treatment accuracy, but also poses a risk of burns due to the moxa stick tipping over. This safety hazard is particularly prominent for children, elderly patients, and those who cannot cooperate independently. For example, while existing navel moxibustion kits increase contact area and improve stability through a wrapping sleeve, they still struggle to solve the problem of precise positioning in dynamic environments. The distance between the moxa stick and the skin fluctuates significantly, affecting the uniformity of the heat stimulation.

[0004] Secondly, the ease of operation and compatibility are lacking. Most moxibustion devices have an integrated moxa stick fixing structure, lacking a flexible adjustment mechanism: on the one hand, circumferential positioning relies on specific-sized slots or needles, only adapting to moxa sticks of a single diameter, failing to meet the diverse needs for moxa stick size in different treatment scenarios; on the other hand, axial fixing often uses threaded tightening or snap-fit ​​structures, requiring repeated rotation or pressing during installation and disassembly, making operation cumbersome, and difficult to quickly adjust the position during moxa stick combustion. While some suspended moxibustion cylinders attempt to adjust the moxa stick height via a screw, circumferential positioning still relies on the overall constraint of the combustion cylinder. When it is necessary to replace the moxa stick or adjust the combustion angle, the entire component must be disassembled, reducing treatment efficiency.

[0005] Third, the structural design is not well-suited to the application scenarios. Existing guide cylinders often feature closed or single-notch designs for their cylinder heads, limiting the insertion path of the circumferential positioning structure and making it impossible to flexibly adjust the fixing angle according to the moxibustion site (such as curved areas like joints and the torso). Furthermore, the connection between the guide cylinder and the cylinder head is mostly fixed welding or threaded connection; when the positioning components inside the cylinder head wear out, the entire guide cylinder needs to be replaced, increasing operating costs.

[0006] In addition, the axial pressure plate and circumferential positioning structure of some devices lack coordination, which can easily lead to axial loosening after the burning column shortens, resulting in unstable heat output. Utility Model Content

[0007] In view of this, in order to overcome the defects of the above-mentioned technology, this utility model provides a clamp for moxibustion installation and fixing.

[0008] The technical solution of this utility model is as follows: The purpose of this utility model is to provide a clamp for fixing moxibustion moxibustion posts, characterized by comprising: The moxibustion cylinder includes a guide cylinder and a guide cylinder cover connected to the lower end of the guide cylinder; The fixed limiting component includes a circumferential positioning structure horizontally inserted on the guide cylinder head and an axial pressure plate structure installed between the guide cylinder and the guide cylinder head; The guide cylinder head includes a guide retaining ring, fan-shaped bosses symmetrically connected on the circumference of the guide retaining ring, and a connecting plate connected between the two fan-shaped bosses. The connecting plate is located at the center of the guide retaining ring, and the top height of the connecting plate is lower than the top height of the two fan-shaped bosses, so as to form two insertion notches between the guide retaining ring, the fan-shaped bosses, and the connecting plate. The circumferential positioning structure is adapted to be inserted into the guide cylinder head from any of the insertion notches to circumferentially position the moxibustion column. The axial pressure plate structure is adapted to press against the top of the circumferential positioning structure and to perform axial positioning of the moxibustion column.

[0009] Optionally, the circumferential positioning structure includes a horizontal insertion plate and an arc-shaped plate vertically connected at the ends, and a plurality of horizontal pins vertically connected to the arc-shaped plate, wherein the horizontal pins are located directly below the horizontal insertion plate and are adapted to be inserted into the interior of the moxibustion column. The horizontal insertion plate is located directly above the connecting plate through the insertion notch, and the arc-shaped plate is adapted to the outer circumferential contour shape of the fan-shaped boss.

[0010] Optionally, the thickness of the horizontal plug-in plate is equal to the difference in height between the top of the connecting plate and the top of the fan-shaped boss.

[0011] Optionally, the horizontal plug-in plate is further provided with two through slots extending along the plug-in direction, and the connecting plate is provided with a connecting hole opposite to the through slot. A first locking member is connected in the through slot and the connecting hole to fix the horizontal plug-in plate and the connecting plate.

[0012] Optionally, the axial pressure plate structure includes an axial pressure plate connected to the top of the two fan-shaped bosses and a vertical pin connected vertically to the bottom surface of the axial pressure plate, the vertical pin being adapted to be vertically inserted into the end of the moxibustion column.

[0013] Optionally, the bottom of the guide cylinder is sealed with a cover, and the cover is provided with two sets of symmetrically arranged first screw holes; the axial pressure plate is provided with a third screw hole opposite to the first screw hole, and the fan-shaped boss is provided with a second screw hole opposite to the third screw hole; a second locking member is connected inside the first screw hole, the second screw hole and the third screw hole.

[0014] Optionally, the outer diameter of the guide cylinder is equal to that of the sector-shaped boss.

[0015] Optionally, there are two horizontal pins and two vertical pins.

[0016] Optionally, the diameter of the moxibustion column is 15-100mm.

[0017] Compared with the prior art, this utility model has at least the following beneficial effects: 1. The moxibustion installation and fixing clamp of this utility model includes a moxibustion cylinder and a fixing and limiting component. The guide cylinder is a hollow cylindrical structure, and the guide cylinder cover, as the lower end sealing component, is installed at the lower end of the guide cylinder by means of buckles, threads, or welding, forming a space at the lower end for accommodating the end of the moxibustion column. When the end of the moxibustion column is placed into the guide cylinder, the circumferential positioning structure is inserted and abuts against the side wall of the moxibustion column. The circumferential positioning structure can restrict its rotation around its own axis through "two-point or multi-point abutment", ultimately achieving a circumferential fixing effect of "the moxibustion column does not rotate or shift". The lower end face of the axial pressure plate structure directly presses against the top of the moxibustion column, and counteracts the tendency of the moxibustion column to move upward through "pressure action" (such as slight expansion when the moxibustion is burning, or upward movement caused by accidental contact during use), ultimately achieving an axial fixing effect of the moxibustion column not moving up and down.

[0018] 2. Compared with traditional moxibustion fixing methods (such as tape adhesion, simple brackets), there is often a problem that the moxibustion column rotates and causes the fire to shift. However, this solution directly restricts the circumferential degree of freedom of the moxibustion column 3 through the horizontal abutment design of the circumferential positioning structure, ensuring that the burning end (lower end) of the moxibustion column is always aligned with the target acupoint, avoiding the fire shift from affecting the moxibustion effect.

[0022] Figure 1-5The image shows a clamp for fixing and installing moxibustion, provided in an embodiment of this utility model. The clamp is used to fix and install a moxibustion column 3. The clamp includes a moxibustion cylinder 1 and a fixing and limiting member 2, wherein: As the core load-bearing structure, the moxibustion cylinder 1 needs to complete the assembly of its own components first to build a basic framework for fixing the moxibustion column 3. Preferably, the moxibustion cylinder 1 includes a guide cylinder 11 and a guide cylinder cover 12, with the guide cylinder cover 12 connected to the lower end of the guide cylinder 11. The fixed limiting component 2 includes a circumferential positioning structure 21 and an axial pressure plate structure 22. The circumferential positioning structure 21 is horizontally inserted on the guide cylinder cover 12 to restrict the rotation or offset of the moxibustion column 3 in the horizontal direction (circumferential direction). The axial pressure plate structure 22 is installed between the guide cylinder 11 and the guide cylinder cover 12 to restrict the up and down movement of the moxibustion column 3 in the vertical direction (axial direction). The guide cylinder head 12 includes a guide ring 121, a fan-shaped boss 122, and a connecting plate 123. The fan-shaped bosses 122 are symmetrically connected to the circumference of the guide ring 121. The connecting plate 123 is connected between the two fan-shaped bosses 122. The connecting plate 123 is located at the center of the guide ring 121, and the top height of the connecting plate 123 is lower than the top height of the two fan-shaped bosses 122, so as to form two insertion notches 13 between the guide ring 121, the fan-shaped bosses 122, and the connecting plate 123. The circumferential positioning structure 21 is adapted to be inserted into the guide cylinder head 12 from any insertion notch 13 to perform circumferential positioning of the moxibustion column 3. The axial pressure plate structure 22 is adapted to press against the top of the circumferential positioning structure 21 and to axially position the moxibustion column 3.

[0023] Specifically, in this embodiment, the guide cylinder 11 is a hollow cylindrical structure, and the guide cylinder cover 12 serves as the lower end closure. It is installed at the lower end of the guide cylinder 11 by means of snapping, threading, or welding, forming a space at the lower end for accommodating the end of the moxibustion column 3. When the end of the moxibustion column 3 is placed into the guide cylinder 11, the circumferential positioning structure 21 is inserted and abuts against the side wall of the moxibustion column 3. If the moxibustion column 3 is cylindrical, the circumferential positioning structure 21 can restrict its rotation around its own axis through "two-point or multi-point abutment"; if the moxibustion column 3 has a flat side wall, the circumferential positioning structure 21 can directly lock its circumferential position through "surface contact", ultimately achieving the circumferential fixing effect of "the moxibustion column does not rotate or deviate"; the lower end face of the axial pressure plate structure 22 directly presses against the top of the moxibustion column 3, and counteracts the upward movement tendency of the moxibustion column 3 through "pressure action" (such as slight expansion during moxibustion burning or upward movement caused by accidental contact during use), ultimately achieving the axial fixing effect of the moxibustion column 3 not moving up and down.

[0024] Compared to traditional moxibustion fixation methods (such as tape adhesion or simple brackets), which often result in the moxibustion column rotating and causing the heat to shift, this solution directly restricts the circumferential freedom of the moxibustion column 3 through the horizontal abutment design of the circumferential positioning structure 21, ensuring that the burning end (lower end) of the moxibustion column 3 is always aligned with the target acupoint, thus avoiding the impact of heat shift on the moxibustion effect.

[0025] Specifically, please refer to Figure 5 As shown, the circumferential positioning structure 21 includes a horizontal insertion plate 211, an arc-shaped plate 212, and a horizontal pin 213, wherein: The horizontal insertion plate 211 and the arc plate 212 are vertically connected at the end. Several horizontal pins 213 are vertically connected to the arc plate 212, and the horizontal pins 213 are located directly below the horizontal insertion plate 211. The horizontal pins 213 are suitable for insertion into the moxibustion column 3. The horizontal insertion plate 211 is located directly above the connecting plate 123 through the insertion notch 13. The arc plate 212 is adapted to the outer circumferential contour shape of the fan-shaped boss 122.

[0026] In this embodiment, the horizontal insertion plate 211 and the arc-shaped plate 212 are vertically connected at their ends to form an "L-shaped" basic frame; several horizontal pins 213 are vertically connected to the inner side of the arc-shaped plate 212 (towards the moxibustion column 3), and their positions are limited to directly below the horizontal insertion plate 211, ensuring that the three form a stable mechanical structure in space. The outline of the arc-shaped plate 212 matches the outer circumferential shape of the fan-shaped boss 122, so that when the horizontal insertion plate 211 is inserted into the insertion notch 13, the arc-shaped plate 212 will naturally fit against the outer side of the fan-shaped boss 122, forming a "double positioning of "inner insertion and outer fitting", avoiding the circumferential positioning structure 21 itself from shifting. The operator can adjust the insertion depth according to the diameter of the moxibustion column 3. When the arc plate 212 fits the outer circumference of the fan-shaped protrusion 122, the optimal positioning position is achieved. The horizontal needle 213 on the inner side of the arc plate 212 is simultaneously inserted into the interior of the moxibustion column 3, and the moxibustion column 3 and the circumferential positioning structure 21 are rigidly connected by physical embedding.

[0027] Therefore, the insertion design of the horizontal needle 213 upgrades the traditional external contact to internal anchoring, fundamentally solving the problem of circumferential sliding of the moxibustion column (especially for cylindrical moxibustion columns).

[0028] The arc-shaped plate 212 and the fan-shaped protrusion 122 are matched to form an external constraint; the horizontal plug plate 211 and the connecting plate 123 are overlapped to form an internal support. The two work together to ensure that the positioning structure itself does not shift, providing a stable reference for the moxibustion column 3.

[0029] Specifically, please refer to Figure 3As shown, the thickness of the horizontal plug-in plate 211 is equal to the difference in height between the top of the connecting plate 123 and the top of the fan-shaped boss 122. Since the top height of the connecting plate 123 is lower than the top height of the fan-shaped boss 122, this height difference creates a stepped installation space. When the horizontal plug-in plate 211 is inserted into place through the plug-in notch 13, the upper surface of the horizontal plug-in plate 211 will be flush with the top of the fan-shaped boss 122, forming a continuous and flat support plane.

[0030] This eliminates the vertical wobbling space of the horizontal insertion plate 211, allowing the horizontal insertion pin 213 to penetrate the moxibustion column 3 at a fixed depth, ensuring consistent positioning during each installation. Because the position of the horizontal insertion plate 211 is strictly defined, the fitting accuracy between the arc-shaped plate 212 and the fan-shaped protrusion 122 is significantly improved, ensuring that the constraint position of the circumferential positioning structure 21 on the moxibustion column 3 remains consistent across different usage scenarios.

[0031] Specifically, please refer to Figure 5 As shown, the horizontal plug-in plate 211 also has two through slots 2111 extending along the plug-in direction. The connecting plate 123 has a connecting hole 1231 opposite to the through slots 2111. The through slots 2111 and the connecting hole 1231 are connected to the first locking member 14 to fix the horizontal plug-in plate 211 and the connecting plate 123.

[0032] Specifically, the through slot 2111 extends along the insertion direction and is consistent with the insertion path of the horizontal plug-in plate 211; the connecting hole 1231 is "directly opposite" on the connecting plate 123 to ensure that the through slot 2111 and the connecting hole 1231 can quickly achieve spatial overlap during the insertion of the horizontal plug-in plate 211.

[0033] After the horizontal insertion plate 211 is inserted into place, the first locking member 14 (which can be a bolt, screw, or other threaded connector) passes through the through groove 2111 and the connecting hole 1231. The extension characteristic of the through groove 2111 allows for fine adjustment of the insertion depth of the horizontal insertion plate 211 within a certain range, ensuring a perfect fit between the arc plate 212 and the fan-shaped boss 122, while also ensuring the optimal depth at which the horizontal insertion needle 213 pierces the moxibustion column 3. Once the position is adjusted to the correct position, tighten the first locking member 14 to rigidly fix the horizontal insertion plate 211 and the connecting plate 123, transforming them from a movable fit into a single integrated structure.

[0034] Specifically, please refer to Figure 5 As shown, the axial pressure plate structure 22 includes an axial pressure plate 221 and a vertical insert pin 222, wherein: The axial pressure plate 221 is connected to the top of the two fan-shaped protrusions 122, and the vertical pin 222 is vertically connected to the bottom surface of the axial pressure plate 221. The vertical pin 222 is adapted to be vertically inserted into the end of the moxibustion column 3.

[0035] Thus, the axial pressure plate 221 is connected to the top of the two fan-shaped bosses 122. The fan-shaped bosses 122 and the horizontal insertion plate 211 are designed with a height difference to form a flush support surface, providing a stable and horizontal mounting reference for the axial pressure plate 221 and ensuring that the vertical insertion needle 222 can be vertically inserted into the moxibustion column 3. By applying vertical pressure, the axial pressure plate 221 moves downward, causing the vertical insertion needle 222 to insert into the top of the moxibustion column 3. Axial positioning is achieved through the physical embedding of the insertion needle. At the same time, the weight of the pressure plate itself or the additional pressure continuously acts on the top of the moxibustion column 3, forming an axial clamping force.

[0036] Specifically, please refer to Figure 3 As shown, the bottom of the guide cylinder 11 is sealed with a cover 111, and the cover 111 is provided with two sets of symmetrically arranged first screw holes 1111; the axial pressure plate 221 is provided with a third screw hole 2211 directly opposite the first screw hole 1111, and the fan-shaped boss 122 is provided with a second screw hole 1221 directly opposite the third screw hole 2211. The first screw hole 1111, the second screw hole 1221 and the third screw hole 2211 are connected with a second locking member 15.

[0037] Thus, this through-type locking system mechanically solidifies the originally dispersed guide cylinder 11, guide cylinder cover 12, and axial pressure plate 221 into a rigid whole, eliminating the fit gaps between the components and increasing the system rigidity several times over. When subjected to external impact, the force is evenly transmitted to the entire structure through the locking chain, avoiding localized deformation.

[0038] Specifically, please refer to Figure 3 As shown, the outer diameters of the guide cylinder 11 and the sector-shaped boss 122 are equal. This ensures that the outer circumferential surface of the guide cylinder 11 and the outer circumferential surface of the sector-shaped boss 122 are completely coplanar, forming a continuous and flat outer cylindrical surface. This coplanar design serves as a visual radial alignment reference when assembling the guide cylinder cover 12 and the guide cylinder 11. Operators only need to observe whether the outer circumferences of both are flush to quickly determine whether the guide cylinder cover 12 is coaxially installed with the guide cylinder 11, avoiding misalignment of subsequent components (such as the axial pressure plate 221) due to radial offset.

[0039] Specifically, please refer to Figure 5 As shown, there are two horizontal pins 213 and two vertical pins 222. The two pins distribute the insertion resistance to two points, which reduces the force required by the operator compared to the concentrated resistance of a single pin, making the insertion process easier. At the same time, it avoids the problem of difficulty in synchronous insertion that may occur with multiple pins (3 or more), and eliminates the need for precise control of the synchronous depth of the pins.

[0040] As a preferred embodiment, the diameter of the moxibustion column 3 is 15-100mm, and the height of the moxibustion column 3 can be selected according to actual needs.

[0041] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this invention.
