[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments:

[0027] See also Figure 1-Figure 2 As shown, the present invention discloses a lumbar traction device, comprising a quick connector assembly 1, an automatic inflation device 2 and a traction waist belt 3, wherein the traction waist belt 3 is provided with a retractable airbag layer 31, wherein the airbag layer 31 comprises a plurality of evenly arranged longitudinal air columns 311 and transverse air columns 312 connecting the longitudinal air columns 311, and after inflation, the two ends of the longitudinal air columns 311 are bent toward the outside of the traction waist belt 3 to form an inverted C shape;

[0028] The quick connector assembly includes a quick connector body 10 and an inflation head 20 matching the quick connector. One end of the quick connector body 10 is connected to the traction waist belt 3, the inflation head 20 is arranged at one end of the inflation tube 4, and the other end of the inflation tube 4 is connected to the automatic inflation device 2.

[0029] The traction waist protection belt 3 is provided with an outer surface layer and an inner surface layer, and the air bag layer 31 is located between the outer surface layer and the inner surface layer.

[0030] Magnetic fasteners 32 are hidden at both ends of the traction waist belt 3, and the magnetic fasteners 32 are fixed between the outer surface layer and the inner surface layer. In the prior art, the traction waist belt is often connected with Velcro. Although Velcro is quick and convenient to bond, it is also easy to bond with hair or thread ends, affecting the bonding effect. The magnetic fasteners 32 are used for convenient connection and effectively solve the above problem.

[0031] The two ends of the traction waist support belt 3 are respectively provided with forks to form four branches 33. When the traction waist support belt 3 is worn, the upper branches and the lower branches at the two ends of the traction waist support belt 3 are respectively connected correspondingly, so that the traction waist support belt 3 can better fit the human body curve.

[0032] A tightening belt 5 is arranged around the traction waist support belt 3, and one end of the tightening belt 5 is fixed to the inner end of the traction waist support belt 3. The tightening belt 5 can make the traction waist support belt 3 fit the human body curve better and fix the traction waist support belt 3 better to the waist.

[0033] The traction waist support belt 3 is provided with an extension belt 6 for extending the length of the traction waist support belt 3 .

[0034] like Figure 7 As shown, the two ends of the traction waist support belt 3 can be connected by an extension belt 6. When the traction waist support belt is not long enough, the extension belt 6 can be used to effectively increase the length.

[0035] Reference Figure 3-Figure 6 As shown, the quick connector body 10 includes:

[0036] A transition seat 11, a side wall of the transition seat 11 is provided with an air outlet 111, and an outer sliding sleeve of the transition seat 11 is provided with a sealing sleeve 12 that seals the air outlet 111 when the quick connector body 10 is closed and does not seal the air outlet 111 when the quick connector body 10 is deflated;

[0037] A shell 13, the shell 13 includes a first pipe section 131 and a second pipe section 132, the inner diameter of the first pipe section 131 is smaller than that of the second pipe section 132, a plurality of holes 133 are arranged on the side of the first pipe section 131, the inner diameter of the hole 133 gradually increases from the inner wall of the shell 13 to the outside, a steel ball 134 is arranged in the hole 133, one end of the second pipe section 132 is connected to one end of the transition seat 11, so that the shell 13 is connected to the interior of the transition seat 11, a movable plug 14 and a first elastic member 15 are arranged in the shell 13, the first elastic member 15 is pressed between the movable plug 14 and the transition seat 11, so that the movable plug 14 is blocked in the first pipe section 131 under normal conditions, and an air inlet hole 141 is arranged on the side wall of the movable plug 14, when the inflating head 20 is inserted, the inflating head 20 presses down the movable plug 14, and the air inlet hole 141 moves down to the second pipe section 132, allowing gas to flow from the inflating head 20 to the quick connector body 10;

[0038] A locking sleeve 16 is sleeved on the outside of the shell 13. The inner wall of the locking sleeve 16 is provided with a groove 161. The locking sleeve 16 and the movable plug 14 jointly squeeze the steel ball 134 under normal conditions. A second elastic member 17 is provided in the locking sleeve 16. The second elastic member 17 abuts between the inner wall of the locking sleeve 16 and the outer wall of the second tube section 132 of the shell 13, so that the groove 161 is away from the steel ball 134 under normal conditions.

[0039] The transition seat 11 and the housing 13 are connected via threads.

[0040] An annular supporting surface 112 is protruded from the inner wall of the transition seat 11 , and the first elastic member 15 abuts between the movable plug 14 and the annular supporting surface 112 .

[0041] A sealing gasket 113 is provided in the transition seat 11 .

[0042] The outer wall of the transition seat 11 is provided with a convex rib 114 , which is a polygonal column. On the one hand, it prevents the sealing sleeve 12 from falling off, and on the other hand, it is convenient for the tool to be screwed when the quick connector body 10 is installed and disassembled.

[0043] Sealing rings 121 are embedded in the upper and lower parts of the sealing sleeve 12. When the quick connector body 10 is connected to the inflation head 20, when the air outlet 111 is in the area between the sealing rings 121, the quick connector assembly 1 is in an air-locking state.

[0044] The housing 13 is sleeved with a retaining ring 135 to prevent the locking sleeve 16 from falling off.

[0045] The air inlet 141 is located in an annular groove 142, and a sealing ring 143 is embedded in the movable plug 14, and the sealing ring 143 is located below the air inlet 141. When the quick connector body is in the original state, the movable plug 14 blocks the first pipe section 131 of the shell 13, and the sealing ring 143 on the movable plug 14 further improves the sealing effect.

[0046] The inflation head 20 is concavely provided with a positioning slot 21 , and is convexly provided with a ring portion 22 , which is located above the positioning slot 21 .

[0047] When the quick connector body 10 is in the original state, the movable plug 14 is blocked in the first pipe section 131 of the shell 13, and the air inlet hole 141 on the side wall of the movable plug 14 can only connect the interior of the movable plug 14 with the first pipe section 131 of the shell 13. When the sealing sleeve 12 seals the air outlet 111, the second pipe section 132 of the shell 13 and the interior of the transition seat 11 are in a closed state, that is, the interior of the quick connector body 10 is in a closed state, and the locking sleeve 16 is pushed up by the second elastic member 17, so that the groove 161 of the locking sleeve 16 is away from the steel ball 134. At this time, the movable plug 14 and the locking sleeve 16 jointly squeeze the steel ball 134.

[0048] When connecting the components, pull the locking sleeve 16 backward. When the groove 161 of the locking sleeve 16 moves to the position of the steel ball 134, insert the inflation head 20 into one end of the shell 13. The inflation head 20 presses down the movable plug 14. When it reaches the position of the steel ball 134, the inflation head 20 squeezes the steel ball 134, forcing the steel ball 134 to deviate toward the groove 161 of the locking sleeve 16. The inflation head 20 can continue to be smoothly inserted into the shell 13 until the ring portion 22 of the inflation head 20 covers the open end of the shell 13, and the positioning groove 21 moves to the position of the steel ball 134. Release the locking sleeve 16, and the groove 161 of the locking sleeve 16 is pushed away from the steel ball 134 by the second elastic member 17 again. The steel ball 134 is tightly clamped in the gap between the locking sleeve 16 and the positioning groove 21 of the inflation head 20, and the connection operation of the inflation head 20 is completed.

[0049] During the connection process, the movable plug 14 gradually moves downward due to the downward pressure of the inflation head 20. When the air inlet hole 141 of the movable plug 14 moves to the second pipe section 132, since the inner diameter of the second pipe section 132 is larger than that of the first pipe section 131, the air inlet hole 141 now connects the interior of the movable plug 14 with the interior of the second pipe section 132 of the shell 13.

[0050] When the inflation head 20 is detached, the locking sleeve 16 is pulled back. When the groove 161 of the locking sleeve 16 moves to the position of the steel ball 134, the inflation head 20 is no longer clamped by the steel ball 134 due to the larger gap between the groove 161 and the positioning slot 21. At the same time, due to the release force of the first elastic member 15, the movable plug 14 is pushed to the first tube section 131 of the shell 13 again, and the inflation head 20 is ejected and can be pulled up smoothly. The locking sleeve 16 is released, and the groove 161 of the locking sleeve 16 is pushed away from the steel ball 134 by the second elastic member 17 again, and the quick connector returns to its original state.

[0051] During inflation, the sealing sleeve 12 covers the air outlet 111 on the sealing transition seat 11, and the gas flows out from the inflation hole of the inflation head 20, passes through the inside of the movable plug 14 and enters the inside of the second pipe section 132 of the shell 13 through the air inlet 141, and then flows through the inside of the transition seat 11 to the inflation product connected to one end of the transition seat 11.

[0052] When deflation occurs, the sealing sleeve 12 slides upward or downward along the transition seat 11 until the air outlet 111 is no longer located between the sealing rings on the sealing sleeve 12 . The air outlet 111 connects the inside of the quick connector body 10 with the outside, and the gas is released from the inside of the quick connector body 10 .

[0053] The automatic inflation device 2 is provided with a battery and a micro inflation pump. The surface of the automatic inflation device 3 is provided with a display screen 2-1 for displaying the inflation gear and the power level. A switch button 2-2 and an inflation button 2-3 are provided below the display screen. A charging port is provided on the side of the automatic inflation device 2.

[0054] How to use the lumbar traction device:

[0055] Before wearing, check whether there is air in the traction waist belt 3, and exhaust it by sliding the sealing sleeve 12 of the quick connector body 10. After exhausting, slide the sealing sleeve 12 in the opposite direction to seal the air outlet 111;

[0056] The traction waist support belt 3 is wrapped around the waist of the human body, worn above the hip bone or below the soft ribs, and the upper branches and lower branches at both ends of the traction waist support belt 3 are respectively connected correspondingly, and the traction waist support belt 3 is adjusted to fit the curve of the human body;

[0057] Connect the quick connector assembly 1, the automatic inflation device 2 is connected to the traction waist belt 3 through the inflation tube, turn on the automatic inflation device 2, and press the inflation button 2-3 to inflate. When inflating, the gas is injected into the airbag layer 31 by the micro-inflation pump through the inflation tube 4 and the quick connector assembly 1. The longitudinal air column 311 of the airbag layer 31 extends in both the upward and downward directions with the hip bone as the support point, generating a strong traction support effect. With the injection of air, the two ends of the longitudinal air column 311 bend and extend toward the outside of the traction waist belt 3, gradually presenting an inverted C arc, which better fits the human waist curve and helps the lumbar spine to restore the normal lumbar curvature.

[0058] After use, the sealing sleeve 12 of the quick connector body 10 can be slid again to exhaust the air.

[0059] The present invention adopts an automatic inflation device to solve the problem of traditional manual inflation. The electric inflation device and the traction waist belt are connected by a quick connector assembly, and the air locking and deflation states can be quickly switched. When deflation occurs, there is no need to manually rotate the screw sleeve, which is convenient and quick, and can also avoid problems such as parts popping out and falling off.

[0060] Of course, the above diagrams are only preferred embodiments of the present invention and are not intended to limit the scope of use of the present invention. Therefore, any equivalent changes made to the principles of the present invention should be included in the protection scope of the present invention.
