Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a wearable protective device for preventing physical damage to the lumbar spine. Background Art

[0002] At present, with the development of modern urban transportation, the accelerated pace of life and the increase of work pressure, more and more people suffer from lumbar pain to varying degrees due to lack of exercise, long-term sitting and other reasons. Most people will choose a waist belt to prevent and relieve lumbar pain, but most of the existing waist belts on the market usually only have a single binding function, and are prone to circumferential dislocation, and cannot provide sufficient support for the abdomen and waist. Therefore, there is an urgent need for a lumbar protection device that can provide support for the lumbar spine to reduce the burden on the waist and prevent the lumbar spine from physical damage. Therefore, a wearable protection device for preventing physical damage to the lumbar spine has emerged.

[0003] For example, an existing patent (publication number: CN220607427U) discloses a waist support belt, which is further fixed by setting a support belt, a pull ring, a fixing buckle, and a support bag, which cooperate with each other to be tightened, and then the support belt and the fixing buckle are buckled and fitted to the waistband, so as to facilitate the support plate to effectively fit the user's waist.

[0004] However, the waist support belt designed as above still has some disadvantages in actual use: although the waist support belt can make the above-mentioned cooperation further fix and make the support plate effectively fit the user's waist, the actual support effect of the support bag is not great due to the material, and the support plate is a steel plate. If the user's lumbar spine is more sensitive, discomfort will occur during use, affecting the use experience and effect.

[0005] To this end, we designed a wearable protective device to prevent physical damage to the lumbar spine to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a wearable protective device for preventing physical damage to the lumbar spine, so as to solve the problems raised in the above-mentioned background technology.

[0007] In order to solve the above technical problems, the utility model provides a wearable protective device for preventing physical damage to the lumbar spine, comprising a belt body, both ends of the belt body are fixedly connected to a belt head, a supporting U-shaped piece is fixedly arranged on the rear side of the belt body, the supporting U-shaped piece is provided with a first spring, the two ends of the first spring are respectively fixedly connected to the inner side walls of the supporting U-shaped piece, an adjusting shell is fixedly arranged on one side of the supporting U-shaped piece, an adjusting rod is rotatably inserted in the adjusting shell, one end of the adjusting rod passes through the supporting U-shaped piece and is fixedly connected to the first spring, a sliding opening is opened at the bottom of the adjusting shell, the other end of the adjusting rod is rotatably inserted in the sliding opening and extends out of the sliding opening, a ratchet is also fixedly sleeved on the adjusting rod, a rotating shaft is fixedly installed in the adjusting shell, a pawl is rotatably sleeved on the rotating shaft, and the pawl abuts against the ratchet.

[0008] Furthermore, a mounting seat is fixedly provided on the top of the pawl, a pin shaft is fixedly provided inside the mounting seat, a pull rod is rotatably sleeved on the pin shaft, and the other end of the pull rod slides through the adjustment shell, and a second spring is movably provided inside the adjustment shell, and the other end of the second spring is fixedly connected to the pawl. The setting of the pull rod and the second spring can adjust the size of the opening arc of the supporting U-shaped part so that it is suitable for use by more people.

[0009] Furthermore, a support sponge is fixedly provided on the front side of the belt body, and a support component is embedded in the support sponge for supporting the patient's waist. The support sponge is made of high-density sponge, which can maintain its shape even after long-term use and is suitable for people who need better support.

[0010] Furthermore, the support assembly includes a third spring, both ends of which are fixedly installed in the support sponge. The third spring is designed to fit the waist curve, help disperse waist pressure, and provide additional support and stability.

[0011] Furthermore, a plurality of limiting belts are fixedly provided on the belt body and the belt head, and a wearing component is commonly installed on the plurality of limiting belts. The setting of the plurality of limiting belts can limit the adjustment belt within the limiting belts, making it easier to clamp and fix the adjustment belt with the belt buckle when wearing.

[0012] Furthermore, the wearable component includes an adjusting belt, which is fixedly mounted on a limiting belt. A belt buckle is rotatably provided at one end of the adjusting belt. The adjusting belt and the belt buckle are engaged with each other, and the engaging design can better fix the device on the user's waist to prevent it from falling off and tilting.

[0013] Furthermore, the outer surface of the supporting sponge and the belt head is provided with anti-skid particles, and the provision of the anti-skid particles can simply limit the overall position of the protective device, increase the friction between the protective device and the surface of the clothing, and facilitate the connection between the adjustment belt and the belt buckle.

[0014] Compared with the prior art, the beneficial effects of the utility model are: 1. When in use, the arc of the support U-shaped part can be adjusted according to the body shape of the user. Each clockwise rotation can stretch and reduce the number of strands of the first spring. Because the pawl and one of the grids of the ratchet wheel are against each other, the pawl and the ratchet wheel are stuck and cannot rotate when the knob is turned counterclockwise, which plays a limiting role and prevents the reverse rotation of the ratchet wheel during movement. When the pull rod is pulled outward, the second spring is compressed to cancel the limiting effect of the pawl. The adjusting rod is rotated counterclockwise to increase the number of strands of the first spring to increase the arc of the support U-shaped part. The size of the support U-shaped part can be freely adjusted to adapt to lumbar fossa of various body shapes to play a supporting role.

[0015] 2. The setting of anti-slip particles can simply limit the overall position of the protective device, increase the friction between the protective device and the surface of the clothing, and facilitate the connection between the adjustment belt and the belt buckle; the setting of multiple limiting belts can limit the adjustment belt within the limiting belt, which makes it easier to connect and fix the adjustment belt with the belt buckle when wearing.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-6 The utility model provides a technical solution: a wearable protective device for preventing physical damage to the lumbar spine, comprising a belt body 1, both ends of the belt body 1 are fixedly connected with a belt head 2, a supporting U-shaped piece 3 is fixedly arranged on the rear side of the belt body 1, a first spring 4 is arranged on the supporting U-shaped piece 3, both ends of the first spring 4 are respectively fixedly connected to the inner side walls of the supporting U-shaped piece 3, an adjusting shell 5 is fixedly arranged on one side of the supporting U-shaped piece 3, an adjusting rod 6 is rotatably inserted in the adjusting shell 5, one end of the adjusting rod 6 penetrates the supporting U-shaped piece 3 and is fixedly connected to the first spring 4, a sliding opening 13 is opened at the bottom of the adjusting shell 5, the other end of the adjusting rod 6 is rotatably inserted in the sliding opening 13 and extends out of the sliding opening 13, a ratchet 7 is also fixedly sleeved on the adjusting rod 6, a rotating shaft 9 is fixedly installed in the adjusting shell 5, a ratchet 8 is rotatably sleeved on the rotating shaft 9, and the ratchet 8 is against the ratchet 7.

[0025] A mounting seat 10 is fixedly provided on the top of the pawl 8, a pin is fixedly provided inside the mounting seat 10, a pull rod 12 is rotatably sleeved on the pin, and the other end of the pull rod 12 slides through the adjustment housing 5, a second spring 11 is also movably provided inside the adjustment housing 5, and the other end of the second spring 11 is fixedly connected to the pawl 8.

[0026] During specific implementation, the knob adjustment rod 6 is used to adjust the arc of the U-shaped support member 3 according to the user's body shape. When the user's body shape is small, the adjustment rod 6 is rotated clockwise to drive the ratchet 7 to rotate. Each rotation of one grid can stretch and reduce the number of strands of the first spring 4, which can play a role in reducing the arc of the U-shaped support member 3. Because the pawl 8 is against one of the grids of the ratchet 7, when the knob is turned counterclockwise, the pawl 8 and the ratchet 7 are stuck and cannot rotate, which can play a limiting role to prevent the reverse rotation of the ratchet 7 during exercise. When the user's body shape is large, the pull rod 12 can be pulled outward. While pulling the pull rod 12, the second spring 11 is compressed to cancel the limiting effect of the pawl 8. At this time, the adjustment rod 6 can be rotated counterclockwise to increase the number of strands of the first spring 4 to increase the arc of the U-shaped support member 3. The size of the U-shaped support member 3 can be freely adjusted to adapt to the lumbar fossa of various body shapes to play a supporting role.

[0027] See also Figure 1-6 As shown, a support sponge 14 is fixedly provided on the front side of the belt body 1, and a support component is embedded in the support sponge 14 for supporting the patient's waist.

[0028] The supporting assembly includes a third spring 15 , and both ends of the third spring 15 are fixedly installed in the supporting sponge 14 .

[0029] A plurality of limiting belts 16 are fixedly arranged on the belt body 1 and the belt head 2, and a wearing component is installed on the plurality of limiting belts 16.

[0030] The wearing component includes an adjusting belt 17 , which is fixedly mounted on the limiting belt 16 , and a belt buckle 18 is rotatably provided at one end of the adjusting belt 17 , and the adjusting belt 17 is engaged with the belt buckle 18 .

[0031] During specific implementation, one end of the adjusting belt 17 is inserted from one side of the limiting belt 16, and after the belt head 2 and the adjusting belt 17 are wrapped around the waist, one end of the adjusting belt 17 is inserted into the belt buckle 18 and the length of the adjusting belt 17 inserted into the belt buckle 18 is adjusted according to the user's body shape and is locked. The third spring 15 embedded in the supporting sponge 14 is designed to fit the waist curve, help disperse the waist pressure, and provide additional support and stability.

[0032] See also Figure 1-6 The outer surface of the supporting sponge 14 and the belt head 2 is provided with anti-skid particles 19. The setting of the anti-skid particles 19 can simply limit the overall position of the protective device, increase the friction between the protective device and the surface of the clothing, and facilitate the connection between the adjustment belt 17 and the belt buckle 18.

[0033] In addition, it should be noted that the support sponge 14 is made of high-density sponge, which can maintain its shape even after long-term use and is suitable for people who need better support, such as the elderly or people with lumbar problems; the third spring 15 is made of high-quality alloy, which has sufficient elasticity and strength to provide the necessary support and stability. This spring is designed to fit the waist curve, help disperse waist pressure, and provide additional support and stability, especially when doing weight training, squats, weightlifting or other activities that require waist strength.

[0034] Working principle: After the belt head 2 and the adjustment belt 17 are wrapped around the waist, one end of the adjustment belt 17 is inserted into the belt buckle 18 and the length of the adjustment belt 17 inserted into the belt buckle 18 is adjusted according to the user's body shape and it is snapped. At this time, the knob adjustment rod 6 needs to be turned according to the user's body shape to adjust the arc of the support U-shaped member 3. When the user's body shape is small, the adjustment rod 6 is rotated clockwise to drive the ratchet 7 to rotate. Each rotation of one grid can stretch and reduce the number of strands of the first spring 4, which can play a role in reducing the arc of the support U-shaped member 3. Because the pawl 8 and the ratchet 7, one of the grids is against each other, so that when the knob is turned counterclockwise, the pawl 8 and the ratchet 7 are stuck and cannot rotate, which can play a limiting role to prevent the reverse rotation of the ratchet 7 during exercise. When the user is large, the pull rod 12 can be pulled outward. While pulling the pull rod 12, the second spring 11 is compressed to cancel the limiting effect of the pawl 8. At this time, the adjusting rod 6 can be rotated counterclockwise to increase the number of strands of the first spring 4 to increase the arc of the support U-shaped member 3. The size of the support U-shaped member 3 can be freely adjusted to adapt to lumbar fossa of various body shapes to play a supporting role.

[0035] In addition, it should be noted that the belt buckle 18 is an accessory at the front end of the belt, which is used to decorate and fix the entire belt. It usually includes a buckle, a buckle body, and a buckle head. The belt is passed through the buckle head, and the buckle body and the buckle ring are abutted against each other to achieve the closure and fixation of the belt, playing a role of limiting and fixing. Since the belt buckle 18 and the installation of the belt buckle 18 are existing technologies, this manual will not explain them in detail.
