[0053] The following will be combined with the drawings in this application to clearly and completely describe the technical solutions in this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0054] See also Figures 1 to 5 , the present application provides a stacking buckle device, the device comprising: a main body module 01, a latch tongue 02, a latch tongue base 03, a return spring 04, a pressure bearing module 05 and a pulley transmission module 06;

[0055] The main body module 01 is provided with a limit block 07, a pressure bearing module 05 and a pulley transmission module 06;

[0056] One end of the pressure bearing module 05 is connected to the pulley transmission module 06 via a steel wire rope 08;

[0057] The tongue base 03 is arranged in the main body module 01, and tongues 02 are arranged on both sides of the tongue base 03, and the tongues 02 extend to the outside of the main body module 01;

[0058] The tongue base 03 abuts against the limit block 07, and the limit block 07 is used to limit the range of movement of the tongue base 03;

[0059] One end of the tongue base 03 abuts against one end of the pressure bearing module 05, and the return spring 04 is arranged between the tongue base 03 and the main body module 01;

[0060] The pulley transmission module 06 controls the movement of the pressure bearing module 05 through the wire rope 08. The pressure bearing module 05 is used to apply pressure to the tongue base 03. After being subjected to pressure, the tongue base 03 will slide downward in the main module 01, thereby driving the tongue 02 to move. When the tongue base 03 slides downward, the reset spring 04 is compressed. When the pressure applied by the pressure bearing module 05 is released, the reset spring 06 is used to reset the tongue base 03.

[0061] The limit block 07 is arranged at one side of the main module 01. The main module 01 is provided with a pressure bearing module 05 and a pulley transmission module 06. The pressure bearing module 05 is connected to the pulley transmission module 06 through a steel wire rope 08. The tongue base 03 is arranged at the bottom of the main module 01. The tongue 02 is mounted on the tongue base 03. The tongue 02 extends to the other side of the main module 01. The tongue 02 is a symmetrical structure. The tongue base 03 abuts against one end of the pressure bearing module 05, and the other end of the tongue base 03 abuts against the limit block 07. The limit block 07 is used to limit the range of motion of the tongue base 03. The reset spring 04 is arranged in the main module 01, connected to the bottom of the tongue base 03, and the other end is connected to the main module 01.

[0062] In the initial state of the stacking buckle device, the tongue base 03 is located at a preset position in the main module 01, and is limited by the limit block 07. The return spring 04 is in an uncompressed state, providing an upward elastic force for the tongue base 03. One end of the pressure bearing module 05 is in contact with one end of the tongue base 03, and no pressure is applied to the tongue base 03 in this state. The pulley transmission module 06 is connected to the other end of the pressure bearing module 05 through the wire rope 08 and is in a standby state. When the tongue 02 needs to be moved, the pulley transmission module 06 is driven by pulling the wire rope 08 to drive the pressure bearing module 05. After being driven by the pulley transmission module 06, the pressure bearing module 05 begins to apply pressure to the tongue base 03. The tongue base 03 slides downward in the main module 01 under the pressure applied by the pressure bearing module 05. When the tongue base 03 slides downward, the tongue 02 is driven to move. In the process of the tongue base 03 sliding downward, the return spring 04 is compressed, and the return spring 04 stores elastic potential energy while being compressed. When the wire rope 08 is loosened, it is reset through the pulley transmission module 06, and the pulling force on the pressure bearing module 05 is released at the same time. The pressure applied by the pressure bearing module 05 to the tongue base 03 disappears, and the reset spring 04 uses elastic potential energy to push the tongue base 03 to move upward, and the limit block 07 limits the tongue base 03 to prevent the tongue base 03 from moving out of the preset area.

[0063] The operator drives the pulley transmission module 06 and the pressure bearing module 05 by pulling the wire rope 08 to control the tongue base 03 and the tongue 02. By using the lever principle, the operator can operate the stacking buckle device more conveniently, simply and labor-savingly. The modular design is adopted. When the parts inside the device are damaged, the parts of the corresponding module can be replaced, which reduces the cost of maintenance and improves the efficiency of maintenance. The reset spring 04 provides a reset function for the tongue base 03 and ensures that the stacking buckle device can still maintain good performance after multiple uses, thereby improving its reliability and stability.

[0064] In an optional embodiment, the main body module includes: an upper cover 011, a shell 012, a lower cover 013 and fixing bolts 014;

[0065] The limit block 07 is arranged on one side of the housing 012;

[0066] The upper cover 011 is arranged on one side of the housing 012, and the lower cover 013 is arranged on the other side of the housing 012;

[0067] The housing 012 is provided with a threaded through hole for installing a fixing bolt 014;

[0068] The upper cover 011 and the lower cover 013 are both provided with threaded holes corresponding to the threaded through holes;

[0069] The fixing bolts 014 connect the upper cover 011 and the lower cover 013 to the housing 012 through the threaded through holes and the threaded holes.

[0070] The main body module 01 is composed of an upper cover 011, a shell 012, a lower cover 013 and a fixing bolt 014. A limit block 07 is arranged on a predetermined side of the shell 012 to limit the range of motion of the tongue base 03. The upper cover 011 is placed on one side of the shell 012, and the lower cover 013 is placed on the other side of the shell 012, so that the threaded holes on the upper cover 011 and the lower cover 013 should be aligned with the threaded through holes on the shell 012, and the fixing bolts 014 are used to pass through the threaded holes of the upper cover 011, the threaded through holes of the shell 012 and the threaded holes of the lower cover 013 in sequence, and the upper cover 011 and the lower cover 013 are installed on the shell 012. The threaded connection method is used to ensure the stability of the connection between the upper cover 011, the shell 012 and the lower cover 013. When the stacking buckle device needs to be maintained or inspected, the upper cover 011, the shell 012 and the lower cover 013 can be separated by unscrewing the fixing bolts 014. The maintenance process becomes convenient and fast, and the maintenance cost is reduced.

[0071] The upper cover 011, the shell 012 and the lower cover 013 are connected by fixing bolts 014 to ensure the overall stability. This allows for easy disassembly and assembly during maintenance. Standardized threaded through holes and threaded holes are used so that the fixing bolts 014 can fix the various components together, simplifying the installation process and improving installation efficiency. Compared with the traditional integrated stacking snap-in device, the stacking snap-in device provided in this solution is more efficient in space utilization, reduces the volume and weight of the stacking snap-in device, and makes the device more convenient and flexible during installation and use.

[0072] In an optional embodiment, both the upper cover 011 and the lower cover 013 are provided with a preset limiting area, and the limiting area is used to limit the range of movement of the latch tongue 02 .

[0073] The upper cover 011, the housing 012, and the lower cover 013 are connected by fixing bolts 014, and the limit block 07 is arranged on one side of the housing 012 to further limit the range of movement of the tongue base 03. The upper cover 011 and the lower cover 013 are both provided with preset limit areas, and the limit areas are used to limit the movement of the tongue 02. The tongue base 03 is installed on the lower cover 013, and the tongue 02 extends outward from both sides of the tongue base 03 and passes through the limit areas of the upper cover 011 and the lower cover 013. When the operator drives the pulley transmission module 06 and the pressure bearing module 05 to apply pressure to the tongue base 03 by pulling the wire rope 08, the tongue base 03 moves downward. The tongue base 03 drives the tongue 02 to move. The range of movement of the tongue 02 will be limited by the upper limit areas of the upper cover 011 and the lower cover 013 to ensure that it moves within a predetermined range.

[0074] The limiting areas of the upper cover 011 and the lower cover 013 limit the range of movement of the latch tongue 02, effectively preventing the latch tongue 02 from exceeding a predetermined range during operation, thereby reducing the risk of equipment damage due to improper operation.

[0075] In an optional embodiment, the limit block 07 further includes a reinforcing rib 071 , one side of the reinforcing rib 071 is connected to the limit block 07 , and the other side of the reinforcing rib 071 is connected to the shell 012 , so as to improve the supporting strength of the limit block 07 .

[0076] When the operator releases the wire rope 08, driving the pulley transmission module 06 and the pressure bearing module 05, and releasing the pressure on the tongue base 03, the reset spring 04 releases the stored elastic potential energy, pushing the tongue base 03 to move upward. The tongue base 03 will be restricted by the limit block 07 to ensure that the tongue base 03 stops at a predetermined position. The reinforcing rib 071 plays a reinforcing role between the limit block 07 and the shell 012, increasing the stability and support strength of the limit block 07. When the tongue base 03 is reset, the elastic potential energy released by the reset spring 04 will cause the tongue base 03 to move quickly, causing a huge impact force. The reinforcing rib 071 can increase the support strength of the limit block 07 and effectively prevent the limit block 07 from being deformed or damaged. The reinforcing rib 071 is connected to the limit block 07 and the shell 012 by welding.

[0077] The reinforcing rib 071 provides a stable support for connecting the limit block 07 and the housing 012, and the support strength of the limit block 07 is improved by connecting the limit block 07 and the housing 012. This makes the stacking buckle device more stable when it withstands the impact force of the tongue base 03 being reset, effectively preventing the limit block 07 from being deformed or damaged, and extending its service life.

[0078] In an optional embodiment, the pressure bearing module 05 includes: a pressure bearing 051, a pressure rod 052, a transmission rod 053 and a bearing support column 054;

[0079] The bearing support column 054 is arranged at a preset position of the lower cover 013, and the pressure bearing 051 is arranged on the bearing support column 054;

[0080] One end of the pressure rod 052 is connected to the pressure bearing 051, and the other end is in contact with the tongue base 03;

[0081] One end of the transmission rod 053 is connected to the pressure bearing 051 , and the other end is connected to the pulley transmission module 06 .

[0082] The pressure bearing 051 is installed on the bearing support column 054. The pressure bearing 051 is connected with a pressure rod 052 and a transmission rod 053. The transmission rod 053 is connected to the pulley transmission module 06 through a wire rope 08. When the operator pulls the wire rope 08, it will pass through the pulley transmission module 06 and drive the transmission rod 053 to move. The transmission rod 053 drives the pressure bearing 051 to rotate. When the pressure bearing 051 rotates, it drives the pressure rod 052 to apply pressure to the tongue base 03. The tongue base 03 moves downward after receiving the applied pressure.

[0083] The pressure bearing 051 is the main transmission component. By connecting the pressure rod 052 and the transmission rod 053, the pressure rod 051 abuts against the tongue base 03, so that the operator can drive the transmission rod 053 by pulling the wire rope 08, and use the lever principle to achieve the purpose of saving effort. The components in the pressure bearing module 05 are modularly designed, so that each component is easy to disassemble and replace. When one of the components is damaged, it can be quickly replaced, reducing the maintenance cost.

[0084] In an optional embodiment, the pulley transmission module 06 includes: a spring chamber 061, an auxiliary pulley 062 and a pulley support column 063;

[0085] The pulley support column 063 is arranged at a preset position of the lower cover 013, and the auxiliary pulley 062 is installed on the pulley support column 063;

[0086] The steel wire rope 08 passes through the spring cavity 061 and is connected to the auxiliary pulley 063;

[0087] The steel wire rope 08 is connected to one end of the transmission rod 053 through the auxiliary pulley 062. The steel wire rope 08 is used to pull the transmission rod 053 to move, thereby driving the pressure bearing 051 to rotate.

[0088] The auxiliary pulley 062 includes a first auxiliary pulley 0621 and a second auxiliary pulley 0622;

[0089] The pulley support column 063 includes a first pulley support column 0631 and a second pulley support column 0632;

[0090] The first auxiliary pulley 0621 is arranged on the first pulley support column 0631;

[0091] The second auxiliary pulley 0622 is disposed on the second pulley support column 0632;

[0092] The steel wire rope 08 passes through the spring cavity 061 , passes through the first auxiliary pulley 0621 and the second auxiliary pulley 0622 in sequence, and is connected to the transmission rod 053 .

[0093] The first auxiliary pulley 0621 is installed on the first pulley support column 0631, and the second auxiliary pulley 0622 is installed on the second pulley support column 0632. The wire rope 08 passes through the spring cavity 061, passes through the first auxiliary pulley 0631 and the second auxiliary pulley 032, and is connected to the transmission rod 053. The first auxiliary pulley 0621 and the second auxiliary pulley 0622 form a pulley group. When the operator pulls the wire rope 08, the wire rope 08 passes through the spring cavity 061, passes through the first auxiliary pulley 0621 and the second auxiliary pulley 0622, and drives the transmission rod 053 to move. The transmission rod 053 drives the pressure bearing 051 to rotate. When the pressure bearing 051 rotates, it drives the pressure rod 052 to apply pressure to the tongue base 03. The tongue base 03 moves downward after receiving the applied pressure.

[0094] The pulley block composed of the first auxiliary pulley 0621 and the second auxiliary pulley 0622 can save effort and change the direction of force. By utilizing the lever principle, the power arm is made twice the resistance arm, so that the operator can control the movement of the buckle by using less force.

[0095] In an optional embodiment, a spring cavity through hole is provided on the housing 012, and the spring cavity 061 is installed in the spring cavity through hole.

[0096] The spring cavity 061 includes: a cavity 0611, a steel wire spring 0612 and a spring washer 0613;

[0097] The steel wire spring 0612 is disposed inside the cavity 0611 , and the spring washer 0613 is disposed on one side of the steel wire spring 0612 .

[0098] The side of the housing 012 is provided with a spring cavity through hole for installing the cavity 0611 of the spring cavity, and the cavity 0611 is provided with a wire spring 0612 and a spring washer 0613. When the operator pulls the wire rope 08, the wire rope 08 passes through the cavity 0611 and pulls the wire spring 0612 through the spring washer 0613, so that the wire spring 0612 is compressed, which plays a role in limiting the pulling stroke and storing elastic potential energy. When the wire rope 08 is released, the wire spring 0612 releases the elastic potential energy and drives the wire rope 08 to reset through the spring washer 0613.

[0099] Through the steel wire spring 0612 inside the spring cavity 061, when the operator pulls the steel wire rope 08, the steel wire spring 0612 can effectively limit the pulling stroke to prevent damage caused by excessive pulling. At the same time, the compression process of the steel wire spring 0612 also plays a buffering role, reducing the impact caused by the pulling force and improving the durability of the equipment. The steel wire spring 0612 stores elastic potential energy during the compression process. When the steel wire rope 08 is released, the steel wire spring 0612 releases the stored elastic potential energy to help the steel wire rope 08 to reset.

[0100] In an optional embodiment, a limit key 081 is provided on the steel wire rope 08, and one end of the limit key 081 is connected to the spring washer 0613;

[0101] A slot corresponding to the limit key 081 is provided inside the cavity 0611;

[0102] When the wire rope 08 is pulled, the limit key 081 will drive the spring gasket 0613 to apply pressure to the wire spring 0612. The wire spring 0612 is compressed after being pressurized. When the wire rope 08 is pulled to the preset position, the wire rope 08 is rotated to make the limit key 081 fit into the slot, so that the wire spring 0612 remains in a compressed state.

[0103] One end of the limit key 081 is connected to the spring washer 0613. When the operator pulls the wire rope 08, the wire rope 08 starts to move, and the limit key 081 on the wire rope 08 is driven. The limit key 081 will drive the spring washer 0613 to move, and pull the wire spring 0612 through the spring washer 0613, so that the wire spring 0612 is compressed, which plays a role in limiting the pulling stroke and storing elastic potential energy. When the wire rope 08 is pulled to the preset position, the operator can rotate the wire rope 08 so that the limit key 081 can be inserted into the preset slot of the cavity 0611. The limit key 081 is inserted into the slot, so that the wire spring 0612 remains in a compressed state. When the wire rope 08 needs to be released, the operator needs to rotate the wire rope 08 in the opposite direction first, so that the limit key 081 leaves the slot, and then release the wire rope 08. After the steel wire rope 08 is loosened, the steel wire spring 0612 releases its elastic potential energy and drives the steel wire rope 08 to reset through the spring washer 0613 .

[0104] By means of the limit key 081 and the slot corresponding to the limit key 081 provided in the cavity 0611, the operator can pull the wire rope 08 to the preset position according to the working situation, and rotate the wire rope 08 so that the limit key 081 is inserted into the slot, and the wire rope 08 is locked in the preset position, so that the wire spring 0612 remains compressed. The wire spring 0612 stores elastic potential energy during the compression process. When the wire rope 08 is released, the wire spring 0612 releases the elastic potential energy to help the wire rope 08 to quickly reset. The design of the limit key 081 and the spring gasket 0613 reduces the direct friction and wear between the wire rope 08 and the wire spring 0612, and prolongs the service life of these components.
