Description

Technical Field

[0001] This utility model mainly relates to the field of watch technology, specifically a watch battery cover that is easy to open and close. Background Technology

[0002] Students and office workers often wear watches to keep track of time. However, most watches stop working after a period of use due to a dead battery. If we could quickly replace the battery ourselves, the watch would continue to function. Currently, to ensure structural stability during daily use, watches typically use screws to secure the battery cover to the watch case. Opening and closing the battery cover to replace the battery requires tools such as screwdrivers, which is inconvenient. Utility Model Content

[0003] The purpose of this invention is to provide a watch battery cover that is easy to open and close, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a watch battery cover that is easy to open and close, comprising a fixed base, the lower end of which is fixedly connected to the watch body, and the upper end of which is detachably connected to an opening and closing cover. The watch body includes a battery compartment located inside the fixed base. A latch and a movable groove are formed on the inner wall of the fixed base. A spring is fixedly arranged in the movable groove along the groove direction. A limit block is fixedly connected to the other end of the spring. A buckle and a limit groove are formed on the opening and closing cover, respectively fitting the latch and the limit block. A pull rod is fixedly arranged on one side of the limit block. The pull rod passes through the spring shaft and the outer wall of the fixed base in sequence. Limit shafts are arranged on both sides of the limit block perpendicular to the spring. A ratchet rack that cooperates with the limit shaft is arranged in the movable groove.

[0005] Preferably, the movable groove and the limiting groove have the same shape and size to accommodate the limiting block sliding radially. The two sides of the limiting groove are recessed to form a sliding groove, the ratchet is located in the sliding groove, and the limiting shaft slides in the sliding groove via the ratchet.

[0006] Furthermore, the tips of the ratchet teeth are rounded and coated with a wear-resistant coating. There are four ratchet teeth in total. The four ratchet teeth are paired up and mesh with the limiting shafts on both sides in the height direction to restrict the limiting blocks from sliding radially.

[0007] Furthermore, when the limiting shaft moves inward to just disengage from the ratchet rack, the spring is in a naturally straight state, and a certain amount of space is still reserved in the limiting groove, so that the limiting block can slide further inward a distance and be bounced back to the ratchet rack position by the spring after the external force is released.

[0008] Preferably, the limiting block is further provided with a first magnetic absorbing piece on both sides perpendicular to the spring, and a second magnetic absorbing piece that cooperates with the first magnetic absorbing piece is provided on the movable groove. When the limiting block slides outward to the position where the limiting shaft just disengages from the ratchet rack, the first magnetic absorbing piece and the second magnetic absorbing piece are magnetically connected.

[0009] Preferably, the outward end of the pull rod forms a handle.

[0010] Preferably, the top of the opening and closing cover forms an opening and closing groove, and the bottom of the opening and closing groove is recessed in the direction of the snap-fit.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This utility model provides a watch battery cover that is easy to open and close. Through the structural cooperation of ratchet and magnetic components, the battery cover can be opened and closed conveniently. After pulling the handle outward, the limiting shaft is disengaged from the ratchet, and the magnetic piece instantly attracts and fixes the limiting block, forming a stable open state lock. The deep recessed opening and closing groove on the top of the cover provides a natural force point. The cover can be separated by lightly prying with the fingertip. The user can complete the operation with one hand by pulling and prying.

[0013] This utility model provides an easy-to-open watch battery cover. A multi-directional meshing structure composed of four ratchet bars, combined with magnetic adsorption, forms a double locking barrier, effectively constraining the displacement of the limiting block. In the closed state, the precise meshing of the ratchet tips and the limiting shaft, along with the interlocking of the buckle and latch, forms a full-range tensile-resistant structure. During long-term use, the spring's design, which maintains a non-stressed state, prevents continuous deformation. The wear-resistant coating on the ratchet teeth enhances durability. The redundant space in the groove allows the spring to push the limiting block automatically against the ratchet end face, using mechanical collision feedback for precise positioning. This ensures accurate reset of the locking mechanism each time the cover is closed, resulting in a stable and durable structure.

Detailed Implementation

[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0025] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] like Figures 1 to 5 As shown, a watch battery cover that is easy to open and close includes a fixing base 1. The lower end of the fixing base 1 is connected and fixed to the watch body 2, and the upper end is detachably connected to an opening and closing cover 3. The watch body 2 includes a battery compartment 6, which is located inside the fixing base 1. The inner wall of the fixing base 1 has a latch 7 and a movable groove 20. A spring 14 is fixedly arranged in the movable groove 20 along the groove direction. The other end of the spring 14 is fixedly connected to a limit block 12. The opening and closing cover 3 has a buckle 10 and a limit groove 8 that respectively fit with the latch 7 and the limit block 12. A pull rod 13 is fixedly arranged on one side of the limit block 12. The pull rod 13 passes through the axis of the spring 14 and the outer wall of the fixing base 1 in sequence. Limit shafts 15 are arranged on both sides of the limit block 12 perpendicular to the spring 14. A ratchet rack 16 that cooperates with the limit shaft 15 is arranged in the movable groove 20.

[0027] The movable groove 20 and the limiting groove 8 have the same shape and size to accommodate the limiting block 12 sliding radially. The two sides of the limiting groove 8 are recessed to form a sliding groove 19. The ratchet 16 is located in the sliding groove 19, and the limiting shaft 15 slides in the sliding groove 19 via the ratchet 16.

[0028] The tips of the ratchet 16 are rounded and coated with a wear-resistant coating, specifically a diamond-like coating. There are four ratchet 16 in total. The four ratchet 16 are paired up and mesh with the limiting shafts 15 on both sides in the height direction to restrict the limiting block 12 from sliding radially.

[0029] When the limiting shaft 15 moves inward until it just disengages from the ratchet rack 16, the spring 14 is in a naturally straight state, and a certain space is still reserved in the limiting groove 8, so that the limiting block 12 can slide inward a distance further and be bounced back to the ratchet rack 16 position by the spring 14 after the external force is released.

[0030] The limiting block 12 is also provided with a first magnetic absorbing piece 17 on both sides perpendicular to the spring 14. The movable groove 20 is provided with a second magnetic absorbing piece 18 that cooperates with the first magnetic absorbing piece 17. When the limiting block 12 slides outward to the position where the limiting shaft 15 just disengages from the ratchet rack 16, the first magnetic absorbing piece 17 and the second magnetic absorbing piece 18 are magnetically connected.

[0031] The outward end of the pull rod 13 forms a handle 4. The handle 4 is disc-shaped and its diameter is greater than that of the pull rod 13. When the cover 3 is closed, there is a certain gap between the handle 4 and the fixed seat 1 to facilitate pulling the handle 4 outward.

[0032] If the pull handle 4 is accidentally caught on the sleeve line after wearing, and the arm shakes and pulls outward, the pulling force is generally small and cannot overcome the ratchet 16 and spring 14. Therefore, it is not easy to separate instantly when pulled outward. In addition, the continuous friction between the pull rod 13 and the ratchet 16 during the outward pulling process will produce a sound to remind the user of an accident and facilitate timely adjustment to avoid damage.

[0033] The top of the opening and closing cover 3 forms an opening and closing groove 11, and the bottom of the opening and closing groove 11 is concave in the direction of the buckle 10, so as to facilitate the application of force along the opening and closing groove 11 to separate the buckle 10 from the latch 7.

[0034] The implementation principle of this application embodiment is as follows: When the product needs to be opened and closed to replace the battery, pinch the handle 4 with two fingers and pull the lever 13 outward to overcome the resistance of the ratchet 16 and the spring 14 until the limiting shaft 15 moves to disengage from the ratchet 16. At this time, the limiting block 12 disengages from the limiting groove 8 and enters the movable groove 20. The first magnetic piece 17 on the limiting block 12 is magnetically connected to the second magnetic piece 18 on the movable groove 20. The ratchet 16 limits the limiting shaft 15 to prevent the spring 14 from rebounding. Then, release the handle 4, insert your finger into the opening and closing groove 11 and pry out the opening and closing cover 3 to expose the battery compartment 6. After replacing the battery, first align the buckle 10 with the latch 7 to secure the opening and closing cover 3 to the fixing base 1. Then, overcome the magnetic force of the magnetic plate and the meshing force of the ratchet to push the pull handle 4 until the limiting shaft 15 moves to just disengage from the ratchet rack 16. At this time, the limiting block 12 enters the limiting groove 8 to limit and fix the opening and closing cover 3. The spring 14 is in a naturally straight state and does not undergo elastic changes for a long time to ensure service life. The sliding grooves 19 on both sides of the ratchet rack 16 have a certain amount of redundancy, so that the limiting block 12 can be elastically driven by the spring 14 to press against both ends of the ratchet rack 16 during the back-and-forth movement. This makes it easy to determine the current position of the limiting block 12 based on the automatic rebound, making it more convenient to use.

[0035] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from its essential characteristics. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
