Technical Field
[0001] This utility model belongs to the field of wearable product technology, specifically relating to a wearable wristband based on vital sign detection. Background Technology
[0002] Wearable wristbands are a common type of electronic wearable product. Existing wearable wristbands are not only for decoration and aesthetics, but also integrate functional components such as vital sign detectors. They have the function of detecting environmental and vital sign data. In complex outdoor environments, people can wear such wristbands to understand their own vital sign data and environmental data in real time, thereby improving their safety in the wild.
[0003] There are several ways to wear a wristband, with Velcro being a common method. The wristband is worn on the wrist by attaching the hook and loop sides of the Velcro together. However, using Velcro alone has the following inconveniences:
[0004] After the Velcro is glued on, if the garment is too loose or too tight, people need to separate the Velcro to adjust it, and then re-glue it, which is not a simple process.
[0005] To address this, we propose a wearable wristband based on vital sign detection. Utility Model Content
[0006] The purpose of this invention is to provide a wearable wristband based on vital sign detection to solve the problems existing in the background art.
[0007] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:
[0008] A wearable wristband based on vital sign detection includes a vital sign detector, a mounting housing, and a wristband, wherein the vital sign detector is disposed inside the mounting housing;
[0009] Both sides of the mounting housing are machined with strip-shaped boxes in the width direction, and both strip-shaped boxes are slidably connected to a U-shaped carriage on both sides in the length direction.
[0010] The number of wristbands is two, and the two wristbands are respectively fixed to the two U-shaped slides. One of the wristbands is processed with a hook and loop surface, and the other wristband is processed with a hook and loop hook surface that matches the hook and loop surface at the end.

[0012] The tension adjustment mechanism includes a linear rack, a transmission gear, and an adjustment knob;
[0013] The number of linear racks is two, and the two linear racks are respectively installed horizontally on the opposite side of the two U-shaped carriages and arranged vertically. The two U-shaped carriages are respectively provided with a first strip groove that matches the two linear racks.
[0014] The transmission gear is rotatably mounted inside the strip-shaped box, and the upper and lower sides of the transmission gear respectively mesh with the two linear racks;
[0015] The transmission gear is fixedly equipped with a rotating rod, which rotates through the strip-shaped box and is fixedly connected to the adjustment knob.
[0016] The locking mechanism includes a horizontal slide bar, a locking block, and a pressing button;
[0017] There are two transverse slide bars, which are installed horizontally on opposite sides of the two U-shaped slides and arranged vertically. The bottom of the upper transverse slide bar and the top of the lower transverse slide bar are provided with several locking slots. The distance between two adjacent locking slots is equal to the distance between two adjacent teeth of the linear rack. The two U-shaped slides are each provided with a second strip groove that matches the two transverse slide bars.
[0018] The number of locking blocks is two, the two locking blocks are symmetrical and each includes a plug and a connecting block. The plug matches the locking slot. The side of each connecting block facing the mounting housing is machined into a wedge shape. The connecting blocks on the upper and lower sides are elastically connected by a first spring.
[0019] The pressing button is located between the two connecting blocks, and both the top and bottom ends of the pressing button on the side away from the mounting housing are machined into wedge-shaped surfaces. The pressing button is elastically connected to the strip box body through a second spring. The pressing button is fixedly connected to a longitudinal positioning rod, and the longitudinal positioning rod passes through the strip box body and is fixedly connected to a button.
[0020] The elastic force of the second spring is greater than that of the first spring;
[0021] The inside of the strip-shaped box is also provided with a vertical positioning square rod, and both of the connecting blocks are provided with square sliding sleeves that match the vertical positioning square rod.
[0022] The outer side of the strip-shaped box is also provided with a ring-shaped protective platform that matches the button, and the surface of the adjustment knob is machined with anti-slip texture.

Detailed Implementation
[0035] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.
[0036] Example 1, such as Figures 1 to 5 The wristband shown includes a vital sign detector 100, a mounting housing 110, and wristbands 120. The vital sign detector 100 is disposed inside the mounting housing 110. Both sides of the mounting housing 110 in the width direction are processed with strip-shaped boxes 111. Both strip-shaped boxes 111 are slidably connected to U-shaped slides 112 on both sides in the length direction. There are two wristbands 120, which are fixed to the two U-shaped slides 112 respectively. One wristband 120 is processed with a Velcro surface 121, and the other wristband 120 has a Velcro hook surface that matches the Velcro surface 121 at its end. One strip-shaped box 111 and one end of the two U-shaped slides 112 are provided with a tension adjustment mechanism, and the other strip-shaped box 111 and the other end of the two U-shaped slides 112 are provided with a locking mechanism.
[0037] like Figure 1 As shown, before wearing the device, the locking mechanism locks the two U-shaped slides 112, so that the two U-shaped slides 112 are locked. When wearing the device, the wristband 120 connecting the two U-shaped slides 112 is glued to the hook side of the Velcro 121, so that the device can be worn on the wrist of the human body. The vital sign detector 100 of the wristband can detect the human body's heart rate, temperature and ambient temperature and air pressure.
[0038] After the wristband 120 is glued, if it is too tight or too loose, traditional equipment requires separating the wristband and re-gluing it to adjust the tightness. However, this equipment does not require separating the wristband; only the following adjustments are needed:
[0039] Step ①: By operating the locking mechanism, the locking of the two U-shaped slides 112 is released, so that the two U-shaped slides 112 can slide relative to the strip box 111;
[0040] Step ②: Operate the tension adjustment mechanism and adjust the two U-shaped slides 112 so that the two U-shaped slides 112 slide away from each other, thereby expanding the tension of the wristband 120, or so that the two U-shaped slides 112 slide close together, thereby reducing the tension of the wristband 120. In this way, the tension of the wristband 120 can be easily adjusted without separating the wristband 120.
[0041] Step 3: After adjusting the tightness, operate the locking mechanism to relock the two U-shaped slides 112, thus completing the adjustment of the tightness.
[0042] In this embodiment, the wristband 120 is designed to be fixed to the U-shaped slide 112. Therefore, when the tightness needs to be adjusted after wearing, the wristband 120 can be tightened by simply releasing the locking mechanism of the U-shaped slide 112 and then adjusting the tightness of the U-shaped slide 112 through the tension adjustment mechanism. There is no need to separate the wristband and re-glu it, making it more convenient to use.
[0043] As a further explanation of the tension adjustment mechanism in this embodiment, such as Figure 2 and Figure 3 As shown, the tension adjustment mechanism includes a linear rack 130, a transmission gear 131, and an adjustment knob 132. There are two linear racks 130, which are horizontally installed on opposite sides of two U-shaped slides 112 and arranged vertically. Each of the two U-shaped slides 112 has a first strip groove that matches the two linear racks 130. The transmission gear 131 is rotatably installed in the strip box 111, and its upper and lower sides mesh with the two linear racks 130 respectively. A rotating rod 133 is fixedly installed on the transmission gear 131. The rotating rod 133 rotates through the strip box 111 and is fixedly connected to the adjustment knob 132.
[0044] After the locking mechanism releases the locking of the two U-shaped slides 112, the tension adjustment mechanism can then perform the following operations:
[0045] Rotating the adjustment knob 132 causes the transmission gear 131 to rotate via the transmission of the rotating rod 133. Since the transmission gear 131 meshes with two linear racks 130 on its upper and lower sides respectively, when the transmission gear 131 rotates, the two linear racks 130 can move away from or towards each other, thereby causing the two U-shaped carriages 112 to move away from or towards each other.
[0046] When the two U-shaped slides 112 move away from each other, the tightness of the wristband 120 can be increased; when the two U-shaped slides 112 move closer to each other, the tightness of the wristband 120 can be decreased. The operation is simple and convenient.
[0047] As a further explanation of the locking mechanism in this embodiment, such as Figures 4 to 5As shown, the locking mechanism includes two horizontal slide bars 140, locking blocks 141, and a push button 142. The two horizontal slide bars 140 are horizontally mounted on opposite sides of two U-shaped slides 112 and arranged vertically. Several locking slots 1401 are provided at the bottom of the upper horizontal slide bar 140 and the top of the lower horizontal slide bar 140. The distance between two adjacent locking slots 1401 is equal to the distance between two adjacent teeth of the linear rack 130. The two U-shaped slides 112 each have a second strip groove that matches the two horizontal slide bars 140. There are two locking blocks 141, which are symmetrical vertically and each includes a plug 1411 and a connecting block 1412. The plug 1411 matches the locking slot 1401, and the two connecting blocks 1412 face the mounting housing 110. One side of each block is machined into a wedge-shaped surface. The upper and lower connecting blocks 1412 are elastically connected by a first spring 1413. The pressing key 142 is located between the two connecting blocks 1412, and both the upper and lower ends of the pressing key 142 away from the mounting housing 110 are machined into wedge-shaped surfaces. The pressing key 142 is elastically connected to the strip box 111 by a second spring 1421. The pressing key 142 is fixedly connected to a longitudinal positioning square rod 1422. The longitudinal positioning square rod 1422 passes through the strip box 111 and is fixedly connected to a button 1423. The elastic force of the second spring 1421 is greater than that of the first spring 1413. A vertical positioning square rod 1414 is also provided inside the strip box 111. Both connecting blocks 1412 are provided with square sliding sleeves 1415 that match the vertical positioning square rod 1414.
[0048] like Figure 4 and Figure 5 In the state shown, button 1423 is not pressed. The elastic force of the second spring 1421 extends the side of the pressing button 142 facing the mounting housing 110 into the space between the two connecting blocks 1412 away from the mounting housing 110, overcoming the elastic force of the first spring 1413 and stretching it elastically. The two connecting blocks 1412 move away from each other and insert the two inserts 1411 into the locking slots 1401 of the upper and lower horizontal slide bars 140 respectively. In this way, the two U-shaped slides 112 are locked by locking the two horizontal slide bars 140.
[0049] When button 1423 is pressed, the second spring 1421 is elastically compressed. Through the guide cooperation of the wedge-shaped surfaces on the upper and lower sides of the pressing button 142 and the wedge-shaped surfaces of the upper and lower connecting blocks 1412, and under the elastic retraction of the first spring 1413, the two connecting blocks 1412 will move closer to each other, so that the two inserts 1411 will exit from the locking slots 1401 of the upper and lower horizontal slide bars 140. In this way, the two U-shaped slides 112 are released and locked by releasing the two horizontal slide bars 140.
[0050] In this embodiment, further explanation is provided. To maintain the effectiveness of the locking mechanism, the distance between two adjacent locking slots 1401 is set to be equal to the distance between two adjacent teeth of the linear rack 130. Thus, when adjustment is made after the lock is released, the movement of the teeth of the linear rack 130 is synchronized with the movement of the locking slots 1401. This ensures that when the locking mechanism is locked, the inserts 1411 of the locking block 141 can be accurately inserted into the corresponding locking slots 1401 of the transverse slide bar 140.
[0051] Meanwhile, in order to maintain the stability of the vertical movement of the locking block 141, a square sliding sleeve 1415 is set in the connecting block 1412 and a vertical positioning rod 1414 is set inside the strip box 111 to achieve the stability of the vertical movement of the locking block 141.
[0052] The working principle of this embodiment is as follows:
[0053] Before wearing the device, the two locking blocks 1411 of the locking mechanism are inserted into the corresponding locking slots 1401 to lock the two U-shaped slides 112. When wearing the device, the wristband 120 connecting the two U-shaped slides 112 is attached to the hook and loop sides via the Velcro loop side 121. If the wristband 120 is too loose or too tight after wearing, pressing the button 1423 utilizes the elastic force of the first spring 1413 to disengage the locking blocks 1411 from the locking slots 1401, releasing the lock on the two U-shaped slides 112. Then, operating the adjustment knob 132, through the transmission gear 131 and the two linear racks 130, allows the two U-shaped slides 112 to move away from each other to adjust the tightness of the wristband 120 or to move closer together. After adjusting the tightness of the wristband 120, since the distance between two adjacent locking slots 1401 is equal to the distance between two adjacent teeth of the linear rack 130, the movement of the teeth of the linear rack 130 is synchronized with the movement of the locking slots 1401. At this time, the button 1423 is released, and the elastic force of the second spring 1421 extends the side of the pressing button 142 facing the mounting housing 110 into the side of the two connecting blocks 1412 away from the mounting housing 110, overcoming the elastic force of the first spring 1413 and stretching it elastically. The two connecting blocks 1412 move away from each other and insert the two inserts 1411 into the locking slots 1401 of the upper and lower horizontal slide bars 140 respectively. In this way, the two U-shaped slides 112 are locked by locking the two horizontal slide bars 140, thus completing the tightness adjustment after the device is worn.
[0054] Example 2 is a functional optimization of the technical solution of Example 1, such as... Figure 6As shown, the outer side of the strip box 111 is also provided with an annular protective platform 200 that matches the button 1423, and the surface of the adjustment knob 132 is machined with anti-slip texture.
[0055] The mounting housing 110 has a placement slot that matches the vital signs detector 100. The surface of the mounting housing 110 is also provided with an annular cover 201, which is fixedly connected to the mounting housing 110 by a number of mounting bolts 202.
[0056] The ring-shaped protective platform 200 can protect the button 1423 and prevent the button 1423 from being too protruding and accidentally touched. The anti-slip texture on the surface of the adjustment knob 132 makes it easy for people to rotate the adjustment knob 132.
[0057] The mounting housing 110 allows the vital signs detector 100 to be placed in the slot provided, and the annular cover 201 is fixed to the mounting housing 110 by the mounting bolts 202, so that the vital signs detector 100 will not fall out and the vital signs detector 100 can be easily disassembled and maintained.
[0058] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
