Description

Technical Field

[0001] This utility model relates to the field of smartwatches, specifically a smartwatch with an adjustable strap length. Background Technology

[0002] A smartwatch is a timepiece with information processing capabilities that meets the basic technical requirements of a watch. Besides telling time, a smartwatch may also have one or more functions such as reminders, navigation, calibration, monitoring, and interaction. Currently, smartwatches are increasingly appearing in daily life, with becoming more complex in function and more sophisticated in internal structure. As user demands continue to rise, smartwatches also feature radio frequency functions such as Bluetooth, GPS outdoor positioning, and 4G voice calling. GPS is particularly useful in scenarios such as outdoor running, hiking, and outdoor cycling.

[0003] Chinese Patent No. CN221997107U discloses a smartwatch with an adjustable strap length, relating to the field of smartwatch technology. It includes a smart watch face and a strap connected to the smart watch face. The strap includes a first strap connected to one side of the smart watch face and a second strap connected to the other side of the smart watch face that is adjustable in length. A retaining buckle is fixedly connected to the end of the first strap away from the smart watch face. The second strap has multiple buckle holes at equal intervals for the retaining buckle to be engaged.

[0004] This invention provides a watch with an adjustable strap length. It features a simple structure, convenient and quick operation, low production cost, and ease of market promotion and use, increasing the watch's usability and effectively adjusting the strap length. However, existing smartwatches with adjustable strap lengths have the following drawbacks during operation:

[0005] (1) The existing device described above requires one hand to press the lever and the other hand to pull the adjustment section when in use, which cannot achieve quick adjustment with one hand;

[0006] (2) The force transmission mechanism that relies on the ejector pin and the wedge groove is prone to failure due to wear after long-term use. Utility Model Content

[0007] The present invention aims to provide a smart watch with an easily adjustable strap length, mainly to solve the technical problem in the prior art where one hand is required to press the lever while the other hand pulls the adjustment section, making it impossible to achieve quick one-handed adjustment.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0009] A smartwatch with an adjustable strap includes a watch face, with straps fixedly connected to both ends. Each strap has several equally spaced holes. The ends of two straps furthest from the watch face overlap, and corresponding holes on the two straps are connected. A rod is inserted into the central hole, passing through the corresponding hole and extending to the outside. A connecting block is located below the watch face, with a first placement groove at one end and a second placement groove at the other end. The first placement slot and the second placement slot are connected. One end of the watch strap near the first placement slot is located in the first placement slot, and the other end of the watch strap near the second placement slot is located in the second placement slot. A first through hole is provided on the bottom surface of the connecting block. A plug rod is slidably connected in the first through hole. The plug rod passes through the corresponding plug hole and extends to the outside. A reset component is provided in the connecting block to facilitate the reset of the plug rod. A limiting component for limiting the plug rod is provided below the connecting block. An adjusting component for adjusting the limiting component is provided on the limiting component.

[0010] The working principle and beneficial effects of this utility model:

[0011] 1. Working principle: The limiting plate is moved outward by squeezing the push block, which releases the constraint on the bottom of the plug rod; the reset spring then pushes the plug rod to automatically pop up and disengage from the watch strap hole to unlock. After adjusting the watch strap, the plug rod is in place, and the compression spring drives the limiting plate to move inward instantly to lock the bottom of the plug rod, thus completing the mechanical self-locking.

[0012] 2. Beneficial effects:

[0013] (1) Existing technology has a simple structure, convenient and quick operation, low production cost, and easy market promotion and use. However, existing devices require one hand to press the lever and the other hand to pull the adjustment section, which cannot achieve quick adjustment with one hand. This solution sets up an adjustment component and a plug rod, so that the plug rod can be automatically popped up by the user only needing to squeeze the push block with one hand. The watch strap is immediately decoupled and slides freely, solving the core pain point of one-handed operation and improving adjustment efficiency.

[0014] (2) This solution sets up a reset component so that the second compression spring drives the limit plate to rebound and lock instantly after the insertion rod is in place. The pure mechanical interaction results in zero force transmission loss and a long service life.

[0015] Preferably, the reset assembly includes a first clearance groove, which is formed on the inner wall of the first placement groove. A first compression spring is fixedly connected in the first clearance groove. A push plate is provided below the first compression spring. One end of the first compression spring is fixedly connected to the inner wall of the first clearance groove, and the other end of the first compression spring is fixedly connected to the bottom surface of the push plate. The bottom surface of the push plate abuts against and is tightly fitted to the top surface of the insertion rod. When the insertion rod is not blocked by the limiting assembly below, the compression spring releases its elastic force and pushes the push plate downward. The push plate then abuts against the top surface of the insertion rod, thereby pushing the insertion rod upward back to its initial position, so that its end protrudes from the bottom of the connecting block, which is convenient for subsequent operation or sensing its status.

[0016] Preferably, the limiting component includes a connecting plate located below the connecting block and fixed to the bottom surface of the connecting block. A third placement groove is formed within the connecting plate, and two limiting plates are disposed within the third placement groove. The limiting plates are slidably connected to the inner wall of the third placement groove. Sliding blocks are fixedly connected to the side walls of both limiting plates. A sliding groove is formed on the inner wall of the third placement groove, and the sliding blocks are located within the sliding groove and slidably connected to the inner wall of the sliding groove. The top surfaces of the two limiting plates are tightly abutted against the bottom surface of the same insertion rod. The connecting plate has a third placement groove containing two slidable limiting plates. The sliding blocks on both sides of the limiting plates are embedded in the sliding grooves on the inner wall of the connecting plate, ensuring that the limiting plates can only move in a specific direction. When the insertion rod is inserted into position, the two limiting plates move inward under the action of spring force, causing their top surfaces to tightly abut against the bottom surface of the insertion rod, forming a mechanical lock to prevent the insertion rod from falling out downwards.

[0017] Preferably, the adjustment component includes two push blocks, which are fixedly connected to the bottom surface of the corresponding limiting plate. The bottom surface of the connecting plate has two second clearance grooves, and the push blocks are located in the second clearance grooves. The push blocks are slidably connected to the inner wall of the second clearance grooves. The push blocks extend downward and are embedded in the second clearance grooves on the bottom surface of the connecting plate, and can slide in the grooves. When the user needs to pull out the plug to adjust the watch strap, he only needs to pinch and move the two exposed push blocks to the sides with his fingers. The push blocks will drive the limiting plate to move outward against the spring force, releasing the limitation on the bottom surface of the plug. At this time, the plug can pop out under the action of the return spring.

[0018] Preferably, the third placement slot is provided with a plurality of second compression springs. The second compression springs are respectively located on one side of the corresponding limiting plate. One end of the second compression spring is fixedly connected to the inner wall of the third placement slot, and the other end of the second compression spring is fixedly connected to the corresponding limiting plate. The second compression springs are respectively located on the outer side of the two limiting plates. One end of the spring is fixed to the inner wall of the third placement slot, and the other end is fixed to the corresponding limiting plate. The spring is in a compressed state and continuously applies an inward pushing force to the limiting plate, forcing the top surface of the limiting plate to press tightly against the bottom surface of the insertion rod, thereby reliably locking the insertion rod and ensuring that the watch strap connection is stable. When the user operates the push block to move the limiting plate outward, these springs are further compressed.

[0019] Preferably, the connecting plate has two second through holes, which are connected to the third placement slot. The third placement slot near the first through hole is connected to the first through hole. The second through holes allow the third placement slot to communicate with the outside, providing space for the push block to move and allowing the user to contact the push block for operation. The connection between the third placement slot near the first through hole and the first through hole is crucial, as it provides space for the insertion rod to pass down from the top of the connecting block and finally reach and be locked by the limiting plate in the third placement slot, thus enabling the insertion, locking and release mechanism of the entire insertion rod to be realized.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figure 1 - Figure 6 As shown, a smartwatch with an adjustable strap length includes a watch face 1. Straps 2 are fixedly connected to both ends of the watch face 1. Each strap 2 has several equally spaced holes 3. The ends of two straps 2 away from the watch face 1 overlap, and the corresponding holes 3 on the two straps 2 are connected. A rod 8 is inserted into the central hole 3, passing through the corresponding hole 3 and extending to the outside. A connecting block 4 is located below the watch face 1. One end of the connecting block 4 has a first placement groove 5, and the other end has a second placement groove 6. A placement slot 5 is connected to a second placement slot 6. One end of the watch strap 2 near the first placement slot 5 is located in the first placement slot 5, and the other end of the watch strap 2 near the second placement slot 6 is located in the second placement slot 6. A first through hole 7 is provided on the bottom surface of the connecting block 4. A plug rod 8 is slidably connected in the first through hole 7. The plug rod 8 passes through the corresponding plug hole 3 and extends to the outside. A reset component is provided in the connecting block 4 to facilitate the reset of the plug rod 8. A limiting component for limiting the plug rod 8 is provided below the connecting block 4. An adjusting component for adjusting the limiting component is provided on the limiting component.

[0029] More specifically, the reset assembly includes a first clearance groove 9, which is formed on the inner wall of the first placement groove 5. A first compression spring 10 is fixedly connected inside the first clearance groove 9. A push plate 20 is provided below the first compression spring 10. One end of the first compression spring 10 is fixedly connected to the inner wall of the first clearance groove 9, and the other end of the first compression spring 10 is fixedly connected to the bottom surface of the push plate 20. The bottom surface of the push plate 20 abuts against and fits tightly with the top surface of the insertion rod 8. The insertion rod 8 is the core connecting component that passes through the insertion hole 3 of the superimposed watch strap 2. The reset assembly consists of the first compression spring 10 and the push plate 20: the spring is compressed and stores energy. When the constraint below the insertion rod 8 is released, the first compression spring 10 pushes the push plate 20, pushing the insertion rod 8 upward. When adjusting the watch strap 2, after the user operates the lower component to release the locking of the insertion rod 8, the insertion rod 8 automatically pops out and disengages from the insertion hole 3 of the watch strap 2, without the need for manual removal, which significantly improves the convenience of operation.

[0030] More specifically, the limiting assembly includes a connecting plate 11, located below the connecting block 4, and fixed to the bottom surface of the connecting block 4. A third placement groove 12 is formed within the connecting plate 11, and two limiting plates 13 are disposed within the third placement groove 12. The limiting plates 13 are slidably connected to the inner wall of the third placement groove 12. Sliding blocks 14 are fixedly connected to the side walls of both limiting plates 13. A sliding groove 15 is formed on the inner wall of the third placement groove 12, and the sliding blocks 14 are located within the sliding groove 15, slidably connected to the inner wall of the sliding groove 15. The top surfaces of the two limiting plates 13 are tightly fitted and abut against the bottom surface of the same insertion rod 8. Two second through holes 19 are formed on the connecting plate 11, and the second through holes 19 communicate with the third placement groove 12. The third placement groove 12, which is close to the first through hole 7, is connected to the first through hole 7. Several second compression springs 16 are provided in the third placement groove 12. The second compression springs 16 are located on one side of the corresponding limiting plate 13. One end of the second compression spring 16 is fixedly connected to the inner wall of the third placement groove 12, and the other end of the second compression spring 16 is fixedly connected to the corresponding limiting plate 13. The two limiting plates 13 slide towards the center under the pre-pressure of the second compression springs 16, and their top surfaces form a "groove" that tightly abuts against the bottom surface of the insert rod 8. The sliding block 14 and the sliding groove 15 cooperate to ensure that the limiting plate moves horizontally without tilting. The spring force forces the limiting plate to continuously clamp the bottom of the insert rod 8, forming a rigid support to prevent the insert rod 8 from accidentally coming loose when worn, thus ensuring the reliability and safety of the watch strap 2 connection.

[0031] More specifically, the adjustment component includes two push blocks 18, which are fixedly connected to the bottom surface of the corresponding limiting plate 13. The bottom surface of the connecting plate 11 has two second clearance grooves 17, and the push blocks 18 are located in the second clearance grooves 17. The push blocks 18 are slidably connected to the inner wall of the second clearance grooves 17. The push blocks 18 are fixedly connected to the bottom of the limiting plate 13 and exposed in the second clearance grooves 17 at the bottom of the connecting plate 11. When the user squeezes the push blocks 18 on both sides, the limiting plate is directly driven to slide outward against the spring force, realizing quick unlocking with one hand. The user does not need tools and can release the constraint of the two limiting plates on the insertion rod 8 simultaneously by pinching with their fingers. The linkage reset component pops out the insertion rod 8, making the adjustment operation extremely efficient and intuitive.

[0032] As can be seen from the above, the specific embodiments of this utility model are as follows:

[0033] The user simultaneously pinches the push blocks 18 on both sides of the bottom of the connecting plate 11 with their thumb and forefinger. The push blocks 18 slide outward along the second clearance groove 17, causing the fixed limiting plate 13 to move horizontally outward. The sliding blocks 14 on both sides of the limiting plate 13 are guided in the sliding groove 15. The second compression spring 16 is further compressed and stored, and the insert rod 8 pops out. When the limiting plate 13 moves outward and disengages from the bottom surface of the insert rod 8: the bottom constraint of the insert rod 8 is released, the first compression spring 10 releases its elastic force instantaneously, pushing the push plate 20 downward. The push plate 20 presses against the top surface of the insert rod 8, and the insert rod 8 pops out downward along the first through hole 7. The insert rod 8 disengages from the insertion hole 3 of the watch strap 2. At this time, the watch... With the strap 2 in a decoupled state, the user slides the two overlapping sections of the strap 2, aligning them with the new target insertion hole 3 according to the wrist size, keeping the strap 2 in a stable position. The user presses down the insertion rod 8 to pass through the new insertion hole 3. The insertion rod 8 moves upward along the first through hole 7, and the bottom of the insertion rod 8 enters the third placement groove 12. The second compression spring 16 is compressed again. When the bottom of the insertion rod 8 passes the top surface of the limiting plate 13, the second compression spring 16 releases its elastic force, driving the limiting plate 13 to quickly reset towards the center. The top surfaces of the two limiting plates 13 tightly clamp the bottom of the insertion rod 8, and the limiting plate 13 forms a mechanical stop under the spring force. The insertion rod 8 is vertically constrained, and the strap 2 enters a stable connection state.

[0034] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
