[0002] Pneumatic diaphragm pumps are a commonly used suction and negative pressure device in physical therapy equipment. However, due to improper design or installation of existing air inlet and exhaust ports, impurities can accumulate in the pump during use (caused by excess moisture and impurities in the skin tissue or sponge during the suction bowl of the physical therapy device). This can lead to clogging of the pump due to impurities inside the pump, seriously affecting the normal use of the physical therapy device and placing an excessive burden on its daily maintenance. Therefore, it is necessary to adjust the existing pneumatic diaphragm pump installation method or redesign the air inlet and exhaust port locations. Utility Model Content

[0003] In response to the problem of easy clogging when pneumatic diaphragm pumps are installed horizontally, the utility model improves a side-mounted fixed shock-absorbing and anti-slip structure for the pneumatic diaphragm pump. It aims to effectively solve the problems of impurity accumulation and clogging in the pump by optimizing the lateral installation structure of the pneumatic diaphragm pump, while improving the shock-absorbing and anti-slip effects, reducing vibration and noise, and ensuring the stability and reliability of the equipment during operation and transportation.

DETAILED DESCRIPTION

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0029] Example 1: Conventional pneumatic diaphragm pump placed horizontally, such as Figure 1 As shown. The pneumatic diaphragm pump used in this embodiment is placed sideways, as shown in FIG. Figure 2 shown.

[0030] Figure 1 The pneumatic diaphragm pump placed horizontally in the middle is prone to produce impurities at the bottom position between the air inlet 11 and the air outlet 12 during use, causing blockage. For example, some tiny impurities that are not separated and discharged in time will slowly accumulate over time and form sediments inside the pneumatic diaphragm pump and affect the suction force of the pneumatic diaphragm pump. In severe cases, the pneumatic diaphragm pump will be blocked. The fundamental reason why impurities cannot be discharged from the pump in time is that the position of the exhaust port is too high. Accordingly, if the pneumatic diaphragm pump is placed sideways with the air inlet 11 at the top and the air outlet 12 at the bottom, at this time, due to the lower position of the air outlet 12, the gravity of the water is used, and under the suction force of the pneumatic diaphragm pump, it is not easy to cause blockage inside the pneumatic diaphragm pump.

[0031] However, due to the vibration and noise generated during normal operation of pneumatic diaphragm pumps, as well as the potential for tilting, jolting, and other abnormal displacements during long-distance transportation, simply placing the pneumatic diaphragm pump sideways is detrimental to its stability, necessitating a suitable mounting structure. This embodiment, by modifying the existing air pump mounting orientation and method, addresses the issue of air pump clogging caused by excess moisture and impurities in skin tissue or sponges during the suction bowl of a physiotherapy device. This not only eliminates clogging associated with pneumatic diaphragm pumps, but also provides structural stability, shock absorption, and anti-slip properties.

[0032] The installation structure of the utility model is as follows Figure 4 After the pneumatic diaphragm pump is fixedly connected to the sheet metal component, the relevant pneumatic diaphragm pump connection component is then connected to the air pump bracket 6 for shock absorption, thereby realizing the connection, fixation, shock absorption and anti-slip functions of the side-mounted pneumatic diaphragm pump. Figure 2 and Figure 3 As shown, by side-mounting the pneumatic diaphragm pump, the air outlet 12 is placed at the bottom. During the pumping process, fine impurities are affected by gravity and deposited near the bottom air outlet 12. During operation, some impurities are blown out more smoothly with the air flow. When the suction force of the pneumatic diaphragm pump is weakened due to impurity blockage, water can be sucked through the pipeline to smoothly clean and remove impurities in the pneumatic diaphragm pump. The specific structure and connection relationship are as follows.

[0033] like Figure 4 and Figure 6As shown, the sheet metal assembly includes an L-shaped sheet metal 3 and a sheet metal clamp 4, wherein the L-shaped sheet metal 3 includes a sheet metal upright 31, a sheet metal flat plate 32, and a sheet metal wing 33. The sheet metal upright 31 is perpendicular to the sheet metal flat plate 32, and the sheet metal wing 33 is located on the left and right sides of the sheet metal upright 31. Mounting holes 16 (each mounting hole 16 is a vertical bar) are provided at the upper and lower portions of the sheet metal wing 33 on both sides. The rear side of the pneumatic diaphragm pump body 1 is fixed to the sheet metal upright 31, and the bottom of the pneumatic diaphragm pump body 1 is pressed against the clamp 52 where the shock-absorbing ball is exposed. After installation, ensure that the air inlet 11 of the pneumatic diaphragm pump body 1 is located on the upper side and the air outlet 12 is located on the lower side.

[0034] like Figure 4 and Figure 5 As shown, corresponding square grooves 10 are provided at the four top corners on the rear side of the pneumatic diaphragm pump body 1. A matching strip fixing nut 2 is provided in each square groove 10, and a screw hole is provided in the center of each strip fixing nut 2. The specific connection between the pneumatic diaphragm pump body 1 and the L-shaped sheet metal 3 is to insert the strip fixing nut 2 into the square groove 10 at the bottom of the pneumatic diaphragm pump (a semi-enclosed strip through hole is provided on the side wall of the square groove 10, and the bottom of the strip through hole corresponds to the screw hole position of the strip fixing nut 2). The strip nut 2 can be fixedly connected to the mounting holes 16 on the upper and lower parts of the sheet metal wing plate 33 by the mounting wire 8. At the same time, the bottom plate of the pneumatic diaphragm pump body 1 is fixed together with the sheet metal flat plate 32, as shown in FIG. Figure 2 and Figure 3 .

[0035] like Figure 4 、 Figure 6 and Figure 8 As shown, the rubber shock absorber 5 includes a shock absorbing ball 51, a clamping base 52, a neck 53, a plug 54, and a waist 55. Main clamping holes 56 are provided at the four corners of the sheet metal plate 32. The neck 53 of each shock absorbing ball 51 is clamped together with the corresponding main clamping hole 56. Each plug 54 is inserted into the socket 17 around the air pump bracket 6, and the waist 55 is clamped into each socket 17.

[0036] To prevent it from falling off, two sheet metal clips 4 can be added on both sides of the sheet metal plate 32. The front and rear ends of the sheet metal clips 4 are respectively provided with auxiliary clip holes 57. When the sheet metal clips 4 and the sheet metal plate 32 are connected through the fixing holes 13 and the fixing wires 14, the auxiliary clip holes 57 are combined with the main clip holes 56 to form a combined clip hole, which can increase the thickness of the clip hole part and ensure that the upper half of the rubber shock absorber is firmly inserted without any gaps. At the same time, after the plug 54 passes through the socket 17, a rubber gasket 9 is installed at the bottom of the socket 17 and the rubber gasket 9 is set inside the waist 55. Figure 7As shown, a rubber gasket 9 of appropriate thickness is inserted into the bottom 55 of the rubber shock absorber 5 to limit its displacement space, tightly connecting the rubber shock absorber to the upper and lower parts, achieving better shock absorption and connection effects. When the pneumatic diaphragm pump is connected, the upper and lower parts of the rubber shock absorber will not fall off under pressure.

[0037] like Figure 7 As shown, a central screw hole 18 (e.g., a sheet metal rivet stud) is fixed to the center of the bottom of the sheet metal plate 32, and a central through-hole 19 is provided in the center of the air pump bracket 6. After a rubber gasket 7 is fitted over a large flat-head mounting screw 8, the large flat-head mounting screw 8 is passed through the central through-hole 19 and then connected to the central screw hole 18. Thus, the bottom of the sheet metal plate 32 and the air pump bracket 6 are connected in the middle by the large flat-head mounting screw 8 and the rubber gasket 7, while the periphery is connected by multiple rubber dampers 5. This provides the pneumatic diaphragm pump with sufficient vibration space while also limiting its extreme displacement, ensuring both shock absorption and anti-slip properties.

[0038] The above-mentioned connection structure has the functions of shock absorption and anti-slip. After experiments, this side-mounted pneumatic diaphragm pump connection solution solves the problem of impurities accumulating at the hollow bottom during long-term suction when the pneumatic diaphragm pump is placed horizontally. At the same time, the side-mounted pneumatic diaphragm pump can also allow water to flow smoothly through the pneumatic diaphragm pump to achieve the purpose of cleaning the inside of the pneumatic diaphragm pump. By strengthening the soft connection between the rubber shock absorber and the sheet metal component, the vibration of the pneumatic diaphragm pump and the noise it generates are greatly eliminated. The connection between the anti-slip large flat head mounting thread 8 and the center screw hole 18 solves the risk of pneumatic diaphragm pump components falling off in extreme conditions and during long-distance transportation while ensuring the vibration space of the pneumatic diaphragm pump.

[0039] Specific steps for using this embodiment are as follows: 1. Equipment Installation: Position the pneumatic diaphragm pump sideways, ensuring the air inlet is at the top and the air outlet is at the bottom. Use an L-shaped sheet metal assembly to secure the pump body to the mounting bracket using square fixing nuts. Flexible connections between the sheet metal bracket and the rubber damper ensure a secure connection between the pump body and the air pump bracket. Use a large center flat-head mounting screw and rubber gasket to secure the pump body in the middle, preventing it from falling during transportation and vibration. This ensures a stable structure, vibration isolation, and secure installation, laying the foundation for stable operation. 2. Equipment Operation: Start the pneumatic diaphragm pump and begin pumping. Due to the sideways position of the pump body, impurities automatically settle near the air outlet under the action of gravity and are then discharged from the device with air or water flow. The rubber damper dampens vibration during operation, reducing noise and protecting internal components from vibration. This process prevents impurity blockage, improves equipment efficiency, reduces vibration and noise, and extends the service life of the device. 3. Cleaning and Maintenance: Regularly clean the pipes and the interior of the pump body with water to thoroughly remove any remaining impurities. Check the connections of the rubber damper, mounting screws, and sheet metal components to ensure they are not loose or damaged. If transporting the equipment, ensure the large flat-head mounting screws and damping balls are securely in place to prevent component displacement or loss. This simple and efficient cleaning process and easy maintenance ensure long-term stable operation and safe transportation of the pump. The above steps ensure efficient and reliable installation, operation, and maintenance of the equipment, avoiding problems associated with traditional installation methods, such as blockage, excessive noise, and component loss, while ensuring long-term performance and stability.

Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention shall be included in the scope of protection of the present invention.
