Description

Technical Field

[0001] This utility model relates to the field of watch accessory technology, specifically a new type of anti-lost wristwatch. Background Technology

[0002] Nursing wristwatches are a common medical aid used to locate psychiatric or Alzheimer's patients. To prevent patients from disassembling the watch themselves, a locking device is usually installed on the wristband. However, current locking devices are often bulky and uncomfortable to wear, and patients may cut the wristband to remove the watch, creating obstacles for treatment and nursing care.

[0003] To address the aforementioned issues, we have made improvements and proposed a new type of anti-loss wristwatch. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] This utility model provides a novel anti-lost wristwatch, including a watch body and a wristband, wherein two wristbands are provided, and the ends of the two wristbands are connected to a locking assembly;

[0006] The locking assembly includes a first locking buckle and a second locking buckle. An insert is fixedly installed on the inner surface of the first locking buckle, and a reserved groove is opened on the inner surface of the second locking buckle. A roller, a limiting ring and a sleeve are installed inside the reserved groove.

[0007] Several reinforcing members are embedded in the inside of the wristband in a crisscross pattern. The top of both wristbands is connected to an elastic band, and the elastic band is covered with a metal braided strip.

[0008] As a preferred embodiment of this utility model, brackets are installed on both sides of the watch body, one end of the elastic band is sleeved on the bracket, the other end of the elastic band is sewn to the end of the wristband, the top two sides of the metal braided band are respectively hinged to the two ends of the bracket, and the length of the metal braided band is the same as the length of the elastic band when stretched to its maximum.

[0009] As a preferred embodiment of this utility model, the number of rollers is the same as the number of plugs. The rollers are sleeved on the outside of the limiting ring. The inner surface of the rollers is provided with a groove. The outer surface of the limiting ring is welded with a protrusion that fits into the groove. A collar is coaxially fixedly connected inside the limiting ring. The edge of the collar is provided with an open slot. The direction of the slot is consistent with the position of the protrusion.

[0010] As a preferred embodiment of this utility model, two limiting members are welded to the lower surface of the plug-in. The distance between the two limiting members is consistent with the length of the collar, and the plug-in is inserted into the inside of the collar. The limiting members can pass through the slots.

[0011] As a preferred embodiment of this utility model, the sleeve is fixedly installed on the innermost side wall of the reserved groove, and the number of sleeves is the same as the number of plug-ins. A sliding plate is slidably connected inside the sleeve, and a spring is fixedly connected between the rear surface of the sliding plate and the inner bottom surface of the sleeve.

[0012] As a preferred embodiment of this utility model, the outer surface of the roller is engraved with the numbers 0-9 in a ring shape.

[0013] As a preferred technical solution of this utility model, the material of the reinforcing member is low carbon steel, and the surface of the wristband is provided with several ventilation grooves.

[0014] The beneficial effects of this utility model are:

[0015] 1. This new type of anti-lost watch connects the first and second locks by inserting the plug into the ring. After rotating the roller, the limiting ring drives the ring to rotate, causing the limiting part to misalign with the slot and making it impossible to pull out the plug. This achieves a password connection between the first and second locks, preventing patients from taking off the watch themselves and reducing the difficulty for caregivers to take off the watch.

[0016] 2. Pre-embedded reinforcements inside the wristband prevent patients from cutting the watch and losing its position. The elastic band keeps the wristband close to the patient's wrist while maintaining a certain degree of elasticity, improving wearing comfort. Since the elastic band material has no shear resistance, a metal braided band is used to cover the outside of the elastic band to prevent it from being cut. This ensures the patient's wearing comfort while preventing them from cutting the watch themselves and thus preventing the patient from getting lost. Attached Figure Description

[0025] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0026] Example: Figures 1-6 As shown, a new type of anti-lost wristwatch includes a watch body 1 and a wristband 2. There are two wristbands 2, and the ends of the two wristbands 2 are connected to a locking assembly 3.

[0027] The locking assembly 3 includes a first locking 301 and a second locking 302. An insert 9 is fixedly installed on the inner surface of the first locking 301. A reserved groove 11 is opened on the inner surface of the second locking 302. A roller 12, a limit ring 13 and a sleeve 16 are installed inside the reserved groove 11.

[0028] Several reinforcing members 6 are embedded in the inside of the wristband 2 in a cross pattern. The top of each wristband 2 is connected to an elastic band 7, and a metal braided band 4 is wrapped around the outside of the elastic band 7.

[0029] The main body of the watch 1 is equipped with brackets 8 on both sides. One end of the elastic band 7 is fitted onto the bracket 8, and the other end of the elastic band 7 is sewn to the end of the wristband 2. The top two sides of the metal braided band 4 are hinged to the two ends of the bracket 8 respectively. The length of the metal braided band 4 is the same as the length of the elastic band 7 when stretched to its maximum. The elastic band 7 allows the wristband 5 to fit snugly against the patient's wrist while maintaining a certain elasticity, thus improving the wearing comfort. The metal braided band 4 is used to cover the outside of the elastic band 7 to prevent the patient from cutting the elastic band 7.

[0030] In addition, the wristband 2 comes in different sizes and lengths depending on the thickness of the patient's wrist. During the wearing process, the wristband 2 should be kept close to the patient's wrist, while the elastic band 7 should be kept stretched but not stretched to its limit. This not only prevents the patient from taking off the watch by using the elasticity of the elastic band 7, but also prevents the wristband 2 from causing pressure damage to the wrist.

[0031] The number of rollers 12 is the same as the number of plug-in 9. The rollers 12 are sleeved on the outside of the limiting ring 13. The inner surface of the rollers 12 has a groove 19. The outer surface of the limiting ring 13 is welded with a protrusion 20 that fits the groove 19. The inside of the limiting ring 13 is coaxially fixedly connected to a collar 14. The edge of the collar 14 has an open slot 15. The direction of the slot 15 is consistent with the position of the protrusion 20.

[0032] Two limiting members 10 are welded to the lower surface of the plug-in 9. The distance between the two limiting members 10 is the same as the length of the collar 14, and the plug-in 9 is inserted into the collar 14. The limiting members 10 can pass through the slots 15.

[0033] The sleeve 16 is fixedly installed on the innermost side wall of the reserved groove 11, and the number of sleeves 16 is the same as the number of plug-in 9. The inside of the sleeve 16 is slidably connected to the slide plate 17, and the rear surface of the slide plate 17 is fixedly connected to the inner bottom surface of the sleeve 16.

[0034] Insert the plug 9 into the collar 14 through the reserved slot 11, and at this time the slot 15 of the collar 14 is aligned with the limiting member 10 of the plug 9. Insert the plug 9 into the sleeve 16 at its end and press the slide plate 17 inward to compress the spring 18. At this time, the two limiting members 10 are located on the front and rear sides of the collar 14 respectively. Move the roller 12. Since the groove 19 of the roller 12 is in contact with the protrusion 20, when the roller 12 rotates, it drives the limiting ring 13 and the collar 14 to rotate together. At this time, the slot 15 is misaligned with the limiting member 10, and the edge of the collar 14 holds the plug 9 to prevent it from being pulled out.

[0035] Similarly, when the roller 12 is turned so that the slot 15 is aligned with the position of the limiting member 10, the slide plate 17 is pushed outward by the spring 18, causing the limiting member 10 to be pushed out from the slot 15, so that the plug 9 can be pulled out and the first latch 301 and the second latch 302 can be separated.

[0036] The outer surface of roller 12 is engraved with the numbers 0-9 in a ring.

[0037] The material of the reinforcement 6 is low-carbon steel, which has a certain toughness and shear resistance, thus preventing the patient from cutting the wristband 2. Several ventilation grooves 5 are opened on the surface of the wristband 2 to improve the comfort of long-term wear.

[0038] Working principle: When using this new type of anti-lost watch, insert 9 is inserted into ring 14 through the reserved slot 11, and at this time the slot 15 of ring 14 is aligned with the limiting member 10 of insert 9. Insert 9 is inserted to its end into sleeve 16, and the sliding plate 17 is pressed inward to compress the spring 18. At this time, the two limiting members 10 are located on the front and rear sides of ring 14 respectively. The roller 12 is turned. Since the groove 19 of roller 12 is in contact with the protrusion 20, when roller 12 rotates, it drives the limiting ring 13 and ring 14 to rotate together. At this time, the slot 15 is misaligned with the limiting member 10, and the edge of ring 14 locks insert 9 to prevent it from being pulled out.

[0039] Similarly, when the roller 12 is turned to the position of the slot 15 and the limiting member 10, the slide plate 17 is pushed outward by the spring 18, causing the limiting member 10 to be pushed out from the slot 15, so that the plug 9 can be pulled out and the first latch 301 and the second latch 302 can be separated.

[0040] The length of the metal braided band 4 is the same as the length of the elastic band 7 when it is stretched to its maximum. The elastic band 7 allows the wristband 5 to fit snugly against the patient's wrist while maintaining a certain degree of elasticity, thus improving wearing comfort. The metal braided band 4 is used to cover the outside of the elastic band 7 to prevent the patient from cutting the elastic band 7.

[0041] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
