[0035] Reference Figures 1 to 4 This embodiment proposes a central lock for a vending machine, which is used to lock the vending machine body 1 and the vending machine door, including: an installation cavity 2, which is opened on the side wall of the vending machine body 1 and has an installation opening 12 and a through opening 9, and the installation opening 12 and the through opening 9 are arranged in sequence; a sliding connection 4 is located in the installation cavity 2 and is slidably arranged; a sliding blocking member 5 is slidably arranged on the sliding connection 4, in sliding contact with the side wall of the installation cavity 2 and used to block the installation opening 12; a lock body 3 is fixedly connected to the sliding connection 4, located in the middle of the vending machine body 1, and the lock body 3 has a lock tongue 8, which is used to pass through the through opening 9.

[0036] In this embodiment, the lock body 3 is located in the middle of the vending cabinet main body 1, so that the upper and lower parts of the vending cabinet door body are locked and constrained at the same time. Compared with the prior art, it avoids the situation where only the upper part is locked while the bottom is at risk of theft, thereby greatly improving the overall safety of the vending cabinet; the lock tongue 8 passes through the through opening 9 and is fixedly connected to the sliding connection member 4 located in the installation cavity 2, and the sliding connection member 4 and the sliding blocking member 5 both slide in the installation cavity 2, so that the extension and retraction of the lock tongue 8 are more stable and accurate, which can ensure the matching accuracy of the lock tongue 8 and the corresponding components, avoid the problem that the lock tongue 8 cannot be normally inserted into the lock hole due to the deviation of the installation position, thereby ensuring the function of the lock body 3. It is reliable and stable; the sliding blocking member 5 is in sliding contact with the side wall of the installation cavity 2, which can effectively block the installation opening 12, preventing dust, debris, etc. from entering the installation cavity 2 and affecting the normal operation of the lock body 3, thereby extending the service life of the lock body 3; the lock tongue 8 is fixedly connected to the sliding connector 4, and is locked with the door of the vending machine through the through-port 9. This structure is more stable and not easily damaged by external forces; even if there is an attempt to open it violently, it can better resist it, providing more reliable security for the goods in the vending machine; the installation cavity 2 is opened on the side wall of the vending machine body 1, making full use of the internal space of the vending machine without taking up additional external space. This is very important for sales places with limited space, as it can increase the storage capacity and functionality of the vending machine without increasing the floor area.

[0037] Furthermore, it also includes a slide rail 7, which is located in the installation cavity 2 and is arranged parallel to the installation cavity 2, and the sliding connector 4 is slidably connected to the slide rail 7.

[0038] In this embodiment, the slide rail 7 provides a stable movement path for the sliding connector 4, making the sliding of the sliding connector 4 inside the installation cavity 2 more precise, which helps to ensure that the lock tongue 8 can accurately pass through the opening 9 and cooperate with the corresponding component on the vending machine door, thereby achieving a reliable locking function; the presence of the slide rail 7 enhances the stability and reliability of the entire central lock structure, and it provides firm support and guidance for the sliding connector 4, so that during frequent use, the various components of the lock body 3 can maintain a good working condition, thereby improving the safety of the vending machine.

[0039] Furthermore, an elastic member 6 is included to connect the sliding connection member 4 and the sliding blocking member 5 . The elastic member 6 is used to provide a force for the sliding blocking member 5 to approach the installation opening 12 and block the installation opening 12 .

[0040] In this embodiment, the elastic member 6 connects the sliding connector 4 and the sliding blocking member 5, providing the sliding blocking member 5 with a force to approach the installation opening 12 and block it, which can ensure that the installation opening 12 always remains in a blocked state when not in operation, effectively preventing impurities such as dust and water vapor from entering the installation cavity 2, protecting the lock body 3 and other internal components from being affected by the external environment, and improving the reliability and service life of the lock; the force of the elastic member 6 makes the sliding blocking member 5 fit tightly against the installation opening 12, enhancing the sealing of the installation cavity 2, which helps to prevent external factors from eroding the internal structure, and also reduces the loosening or failure of internal components due to poor sealing, thereby ensuring the normal operation of the lock; the elastic member 6 can play a buffering role to a certain extent. When the vending machine is subjected to external impact or vibration, the elastic member 6 can absorb part of the energy, reduce the impact on components such as the lock body 3, the sliding connector 4 and the sliding blocking member 5, reduce the risk of damage, and improve the stability and durability of the lock.

[0041] Furthermore, the distance between the sliding blocking member 5 and the locking tongue 8 is equal to the distance between the installation opening 12 and the through opening 9 .

[0042] In this embodiment, when the distance between the sliding blocking member 5 and the lock tongue 8 is equal to the distance between the installation opening 12 and the through opening 9, it can ensure that when the lock tongue 8 is extended, it can accurately pass through the through opening 9 and cooperate with the lock hole to achieve an efficient and accurate locking function; it avoids the situation where the lock tongue cannot be accurately inserted into the lock hole or is not inserted into place due to distance mismatch, thereby improving the reliability and stability of the lock; this equidistant design makes the structure of the entire vending machine center lock more compact and reasonable, and the positional relationship between the various components is clearer, which is conducive to improving the efficiency of installation and maintenance; at the same time, it also reduces the interference and collision that may be caused by unreasonable component positions, thereby extending the service life of the lock.

[0043] Furthermore, the sliding connection member 4 has a receiving groove 13 , the sliding blocking member 5 is slidably disposed in the receiving groove 13 , and the elastic member 6 is located in the receiving groove 13 .

[0044] In this embodiment, the accommodating groove 13 of the sliding connector 4 provides installation space for the sliding blocking member 5 and the elastic member 6, making the structure of the entire vending machine central lock more compact, reducing the occupied space, and being conducive to the rational use of the internal space of the vending machine, while also making the appearance of the lock more simple and beautiful; the sliding blocking member 5 is slidably arranged in the accommodating groove 13, which can better maintain the stability of its movement. The accommodating groove 13 provides a guiding and limiting function for the sliding blocking member 5 to prevent it from deflecting or shaking during movement, thereby ensuring that the sliding blocking member 5 can accurately block the installation opening 12; the elastic member 6 is located in the accommodating groove 13 and can be better protected. The accommodating groove 13 can prevent the elastic member 6 from being hit or squeezed by external objects, thereby avoiding damage or deformation of the elastic member 6 due to external force, thereby ensuring that the elastic member 6 can continue to provide the sliding blocking member 5 with force to block the installation opening 12.

[0045] Furthermore, both ends of the sliding blocking member 5 have guiding slopes 10 .

[0046] In this embodiment, the guide bevels 10 at the lower ends of the sliding sealing member 5 play a guiding role during the installation process. When the sliding sealing member 5 is installed in the installation cavity 2, the guide bevels 10 can make it easier for the sliding sealing member 5 to enter the installation position, reducing the difficulty of installation and improving installation efficiency. During the sliding process of the sliding sealing member 5, the guide bevels 10 can reduce the friction resistance with the inner wall of the installation cavity 2, making the sliding sealing member 5 slide more smoothly, avoiding the occurrence of jamming or stuck, ensuring that the sliding sealing member 5 can quickly respond to the movement of the lock body 3 and achieve timely blocking and opening of the installation port 12. When the sliding sealing member 5 blocks the installation port 12, the guide bevels 10 can better fit with the edge of the installation port 12, increase the contact area, improve the sealing performance, effectively prevent dust, water vapor and other impurities from entering the installation cavity 2, and protect the normal operation of the lock body 3 and other internal components.

[0047] Furthermore, a side of the installation opening 12 close to the installation cavity 2 has an abutting inclined surface 11 , and the guiding inclined surface 10 is used to be placed in the abutting inclined surface 11 .

[0048] In this embodiment, when the guide bevel 10 is placed in the abutting bevel 11, the two bevels fit tightly together to form a reliable barrier. This fitting method effectively increases the contact area, thereby improving the sealing at the installation port 12; it can better prevent dust, water vapor and other impurities from entering the installation cavity 2, which is crucial for protecting the lock body 3 and key components such as the internal sliding connector 4 and elastic member 6, ensuring that they operate stably in a clean environment, and extending the service life and reliability of the central lock of the vending machine; the cooperation between the abutting bevel 11 and the guide bevel 10 provides stable support and guidance for the sliding sealing member 5. During the movement of the sliding sealing member 5, the guide bevel 10 slides along the abutting bevel 11, providing the sliding sealing member 5 with a clear motion trajectory and guidance. This guiding effect makes the movement of the sliding sealing member 5 more stable and accurate, avoiding the occurrence of unstable situations such as shaking, offset or jamming. The bevel cooperation helps to disperse the force exerted on the sliding sealing member 5 during movement. When external forces act on the sliding block member 5, the inclined surfaces evenly transfer and distribute the forces to the sidewalls of the mounting cavity 2, reducing localized stress concentration and improving the stability and durability of the entire structure. The design of the abutting bevel 11 and the guiding bevel 10 makes the structure of the mounting opening 12 and the sliding block member 5 more compact and rational. The coordinated design of the inclined surfaces fully utilizes space, making the structure of the mounting opening 12 and the sliding block member 5 even more compact. This achieves improved sealing and operational performance without increasing additional space, providing greater flexibility in the overall design of the vending machine.

[0049] Furthermore, a side of the sliding blocking member 5 away from the elastic member 6 is flush with the installation opening 12 .

[0050] In this embodiment, when the sliding sealing member 5 is flush with the mounting opening 12, it can better fit the edge of the mounting opening 12, further improving the sealing performance of the mounting cavity 2. This effectively prevents the ingress of impurities such as dust and moisture, protecting the internal lock body 3 and other components from the external environment. The flush design reduces interference with the sliding sealing member 5 by external objects. In daily use, the sliding sealing member 5 is less likely to shift or be damaged by collisions or scratches, ensuring the normal operation and service life of the lock. The flush surface is easier to clean and maintain. When cleaning the vending machine, the area around the mounting opening 12 can be wiped more conveniently without blind spots caused by the protruding sliding sealing member 5, reducing maintenance costs and difficulty.

[0051] Furthermore, the opening 9 is circular.

[0052] In this embodiment, the through opening 9 is circular, which is relatively easy to realize during the processing. The circular shape can be processed by simple drilling and other processes, which reduces the processing difficulty and cost. At the same time, when assembling the lock body 3 and the sliding connector 4, the circular through opening also makes it easier for the lock tongue 8 to pass through accurately, thereby improving the assembly efficiency. The circular through opening 9 can evenly disperse the stress generated by the lock tongue 8 during the extension and retraction process, thereby avoiding damage to the side wall or other components of the installation cavity 2 due to stress concentration, thereby improving the structural strength and stability of the entire vending machine center lock. The circular through opening provides a smoother channel for the movement of the lock tongue 8. Compared with through openings of other shapes, the gap between the circular through opening and the lock tongue is more uniform, thereby reducing the friction resistance and jamming phenomenon during the movement of the lock tongue, thereby ensuring that the lock tongue can quickly and accurately realize the locking and unlocking functions.

[0053] Furthermore, the mounting opening 12 is square.

[0054] In this embodiment, the installation opening 12 is square, which provides a larger operating space when installing the lock body 3, sliding connector 4 and other components. The installer can more conveniently place these components into the installation cavity 2 for installation and debugging, thereby improving the installation efficiency. At the same time, during the later maintenance process, the square installation opening is also convenient for maintenance personnel to perform inspection and maintenance operations; the square installation opening 12 is easier to match the shape of the installation cavity 2, making the structure of the installation cavity 2 more stable. When subjected to external force, the square shape can better disperse stress and reduce the possibility of deformation of the installation cavity 2, thereby improving the structural strength and stability of the entire vending machine center lock; the square installation opening can better cooperate with the sliding sealing member 5 to achieve sealing and protection of the installation cavity 2. The sliding sealing member 5 can fit the edge of the square installation opening more closely, effectively preventing impurities such as dust and water vapor from entering the installation cavity 2, and protecting the normal operation of the internal lock body 3 and other components.
