Description

Technical Field

[0001] This utility model relates to the field of luggage technology, specifically a luggage with a flexible push-button switch. Background Technology

[0002] The opening and closing mechanism of a bag is one of the core components that enables the opening and closing function of the bag product, and its design directly affects the user experience and the reliability of the product. Currently, common bag opening and closing methods mainly include mechanical structures such as latches, zippers, and pins. These structures mostly achieve the fixing or separation of the lid and the body through manual operation, and often rely on elastic elements such as springs to assist in resetting or provide closing force. This type of opening and closing mechanism is widely used in various bag products such as trolley cases, storage boxes, and toolboxes, constituting a traditional and widely used technical solution in this field.

[0003] In the prior art, Chinese patent application number 2023236643821 discloses a safety bag with elastic fasteners, including a bag body and a lid rotatably mounted on the bag body. Several elastic fasteners are rotatably mounted on the lid. Two opposing fixing blocks are provided on the lid and bag body. Each fixing block has a through hole. Reinforcing ribs and supporting protrusions are provided inside the bag body. The bag body has a cavity. A lower annular plate is provided on the outer side of the bag body at the edge of the cavity opening. The lower annular plate is bent downwards to form an annular groove with a gap from the surface of the bag body. A notch is provided on the lower annular plate to mate with the elastic fasteners. An upper annular plate is provided on the outer side of the lid. The upper annular plate is bent upwards. The upper annular plate is opposite to the lower annular plate. A fixing notch is provided on the upper annular plate. Fixing plates are provided on both sides of the fixing notch. This structure often requires two hands to operate, and the locking and unlocking methods are different. In scenarios where items need to be placed quickly, it is difficult to open the elastic fasteners when holding items with both hands, which is very inconvenient. Utility Model Content

Detailed Implementation

[0013] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0014] This utility model provides an improved version of a bag with a resilient push-button switch. The technical solution of this utility model is as follows: like Figures 1-6 As shown, a bag with a resilient push-button switch mainly includes a bag body 1 and a bag lid 2 that is rotatably connected to the bag body 1 via a hinge. An annular block 3 is fixedly installed on the outer surface of the upper part of the bag body 1, extending along the upper edge of the bag body 1. At each of the two ends of the annular block 3, a slot 4 is respectively opened on its end face. An insert plate 7 is slidably installed in each slot 4. The two insert plates 7, located at their ends outside the bag body 1, are fixedly connected to the inner side of a push-button plate 8, making the push-button plate 8 and the two insert plates 7 a single, interconnected component.

[0015] At the bottom of each slot 4, between the end of the insert plate 7 away from the pressing plate 8, a first spring 6 is connected. One end of the first spring 6 is fixed to the insert plate 7, and the other end is fixed to the bottom of the slot 4. In the unlocked state, the first spring 6 is in its natural state, and its elastic force tends to push the insert plate 7 outward from the slot 4, thereby keeping the pressing plate 8 protruding from the surface of the housing 1.

[0016] A limiting groove 5 is formed on the outer surface of the annular block 3. A limiting post 10 is fixedly installed on the outer side of each insert plate 7. One end of the limiting post 10 is fixed to the insert plate 7, and the other end passes through and slides into the limiting groove 5 on the annular block 3, extending to the outside of the annular block 3. The end of the limiting post 10 extending out of the limiting groove 5 is rotatably connected to one end of the transmission rod 11 by a hinge. The other end of the transmission rod 11 is vertically fixedly connected to a sliding post 12.

[0017] A guide sliding part is provided on the annular block 3. This guide sliding part has a specific channel system inside. The sliding post 12 is adapted to and located within this channel system. When the pressing or releasing of the pressing plate 8 causes the insert plate 7 and the limiting post 10 to reciprocate, the limiting post 10 drives the sliding post 12 to slide along a specific path within the channel of the guide sliding part via the transmission rod 11. Since the length of the transmission rod 11 is fixed, different positions of the sliding post 12 within the channel will, in turn, limit the length of the insert plate 7 extending out of the slot 4 via the transmission rod 11 and the limiting post 10, thereby achieving two stable extension positions.

[0018] On the outer surface of the housing 1, on the same side as the pressing plate 8, a limiting strip 20 is also fixedly installed. On the inner side of the lid 2, at a position corresponding to the limiting strip 20 on the housing 1, a movable limiting mechanism is installed. When the user presses the pressing plate 8, as the extension length of the insert plate 7 changes, the pressing plate 8 will press against or disengage from the movable limiting mechanism to varying degrees. When the insert plate 7 extends to a shorter position, the pressing plate 8 pushes the movable limiting mechanism to a position where it engages with the upper limiting strip 20 of the housing 1, thereby locking the lid 2; when the insert plate 7 extends to a longer position, the pushing force of the pressing plate 8 on the movable limiting mechanism decreases or disappears, and the movable limiting mechanism disengages from the limiting strip 20 under its own elasticity or structural action, allowing the lid 2 to open.

[0019] Furthermore, the main body of the guide sliding part is a channel system formed inside the annular block 3. It includes an initial reciprocating channel 13. In the latter half of the reciprocating channel 13, a fixed blocking block 18 is provided, which divides the channel into two independent branches: one is a process channel 14, and the other is a return channel 19. The entrance end of the process channel 14 and the exit end of the return channel 19 are both connected to the front section of the reciprocating channel 13, and the exit end of the process channel 14 is connected to the upper end of the first falling channel 15. The entrance end of the return channel 19 is connected to the lower end of the second falling channel 16. The first falling channel 15 and the second falling channel 16 are downward sloping channels. The lower end of the first falling channel 15 and the upper end of the second falling channel 16 are smoothly connected by an inclined guide ramp 17. The guide ramp 17 allows the sliding column 12 sliding down from the first falling channel 15 to be automatically guided into the upper entrance of the second falling channel 16.

[0020] The working process is as follows: Initially, the lid 2 is open, and the sliding column 12 is located at the end of the reciprocating channel 13. Upon first pressing of the pressing plate 8, the insert plate 7 moves inward, pushing the sliding column 12 from the bottom of the first falling channel 15 via the transmission rod 11. At this point, pressure is stopped, and the first spring 6 pushes the insert plate 7 partially back. The sliding column 12 moves along the guide ramp 17 to the top of the second falling channel 16. At this point, the sliding column 12 is stuck at the bottom of the blocking block 18, restricting the insert plate 7 from fully retracting and maintaining a certain extension. This pushes the movable limit mechanism to lock the limit strip 20 in a locked state. Upon second pressing of the pressing plate 8, the sliding column 12 falls from the top to the bottom of the second falling channel 16. Pressure is stopped, and the insert plate 7 returns under the action of the spring. The sliding column 12 leaves the second falling channel 16, passes through the reciprocating channel 14, and returns to the top of the reciprocating channel 13. The movable limit mechanism is released and in an unlocked state. This cycle repeats. Furthermore, the movable limiting mechanism includes an L-shaped fixing block 21, the vertical side of which is fixed to the outer wall of the box cover 2. A locking block 22 is slidably connected to the bottom of the horizontal side of the L-shaped fixing block 21. A cavity 23 is opened inside the locking block 22, and multiple parallel, elongated grooves 24 are opened on the top surface of the locking block 22.

[0021] At the bottom of the horizontal edge of the L-shaped fixing block 21, multiple insert rods 25 are fixedly installed, corresponding to the number and position of the sliding grooves 24. These insert rods 25 extend vertically downward and are respectively inserted into the corresponding sliding grooves 24 on the top surface of the locking block 22. The length direction of the sliding grooves 24 determines the horizontal sliding direction of the locking block 22 relative to the L-shaped fixing block 21. A baffle 26 is also fixedly connected between two adjacent insert rods 25. The baffle 26 is located inside the cavity 23 of the locking block 22 and can fix the insert rods 25 inside the cavity 23.

[0022] Inside the cavity 23, one end of a second spring 27 is fixedly connected to the side of each baffle 26 facing away from the vertical edge of the inner sidewall of the lid 2. The other end of the second spring 27 is fixedly connected to the sidewall of the cavity 23 opposite to the baffle 26. Therefore, the elastic force of the second spring 27 always tends to push the locking block 22 toward the lid 2.

[0023] When the lid 2 is closed, the upper surface of the locking block 22 is against the lower surface of the upper limit strip 20 of the box body 1. In the locked state, the pressing plate 8 extends slightly, its end abutting against the outer end of the locking block 22, overcoming the elastic force of the second spring 27, and pushing the entire locking block 22 inward, causing it to move inward to the lower side of the limit strip 20, thus achieving locking. In the unlocked state, the pressing plate 8 extends further, reducing or eliminating the pressure on the locking block 22, and the locking block 22 is pushed outward under the action of the second spring 27, thereby disengaging from the limit strip 20.

[0024] Furthermore, at the end of each insert plate 7 furthest from the pressing plate 8, two outwardly protruding feet 9 are integrally formed or fixedly connected. These two feet 9 can be sheet-like, block-like, or columnar. Correspondingly, one end of each first spring 6 is sleeved or connected to one of the feet 9, while the other end rests against or is connected to the bottom of its corresponding slot 4. The arrangement of the two feet 9 and the two first springs 6 provides the insert plate 7 with two symmetrical elastic support points and force-bearing points, making the force on the insert plate 7 more balanced and stable when it reciprocates within the slot 4. This reduces the uneven wear and jamming that may be caused by single-point force, and improves the smoothness of movement and the durability of the structure.

[0025] Furthermore, a protective housing is installed on the outer side of the area where the guide sliding part is opened or installed on the annular block 3. This protective housing encloses the channel of the guide sliding part, the sliding post 12, and part of the transmission rod 11 within its internal space. Its main function is to prevent external dust, small debris, etc., from entering the complex channel and avoiding jamming of the sliding post 12; at the same time, it can also prevent accidental contact by the user or impact by external objects on the transmission rod 11 or the sliding post 12, which could cause deformation, disengagement from the track, or affect the switching function, thereby improving the dustproof, foreign object-proof, and anti-accidental interference capabilities of the entire elastic push-button switch mechanism and ensuring long-term reliability.

[0026] The foregoing description enables those skilled in the art to implement or use this invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this invention. Therefore, this invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
