[0053] The technical solutions in this application will be described clearly and completely in this application combined with the drawings in this application. Obviously, the described embodiments are only a part of the embodiments of this application, not all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of this application.

[0054] Please refer to Figures 1 to 5 The application provides a stacking buckle device, which comprises a main body module 01, a clamping tongue 02, a clamping tongue base 03, a reset spring 04, a pressure bearing module 05 and a pulley transmission module 06.

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

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

[0057] The clamping tongue base 03 is arranged in the main body module 01, and the clamping tongue base 03 is provided with the clamping tongue 02 on both sides, and the clamping tongue 02 extends outwardly from the main body module 01;

[0058] The clamping tongue base 03 abuts against the limiting block 07, and the limiting block 07 is used for limiting the activity range of the clamping tongue base 03;

[0059] One end of the clamping tongue base 03 abuts one end of the pressure bearing module 05, and the reset spring 04 is arranged between the clamping 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 steel wire rope 08, the pressure bearing module 05 is used to apply pressure to the clamping tongue base 03, and the clamping tongue base 03 will slide downward in the main body module 01 after being subjected to pressure, thereby driving the clamping tongue 02 to move, when the clamping tongue base 03 slides downward, the reset spring 04 is compressed, and when the pressure applied by the pressure bearing module 05 is released, the reset spring 06 is used to reset the clamping tongue base 03.

[0061] The limiting block 07 is arranged on one side inside the main body module 01, the main body module 01 is internally provided with the pressure bearing module 05 and the pulley transmission module 06, and the pressure bearing module 05 is connected with the pulley transmission module 06 through the steel wire rope 08. The clamping tongue base 03 is arranged at the bottom of the main body module 01, the clamping tongue 02 is installed on the clamping tongue base 03, the clamping tongue 02 extends to the other side of the main body module 01, and the clamping tongue 02 has a symmetrical structure. One end of the clamping tongue base 03 abuts one end of the pressure bearing module 05, and the other end of the clamping tongue base 03 abuts the limiting block 07, and the limiting block 07 is used to limit the movement range of the clamping tongue base 03. The reset spring 04 is arranged inside the main body module 01 and connected with the lower part of the clamping tongue base 03, and the other end is connected with the main body module 01.

[0062] In the initial state of the stacking buckle device, the clamping tongue base 03 is located at a preset position inside the main body module 01 and is limited by the limiting block 07, and the reset spring 04 is in an uncompressed state and provides upward elastic force for the clamping tongue base 03. One end of the pressure bearing module 05 abuts one end of the clamping tongue base 03, and no pressure is applied to the clamping tongue base 03 in this state. The pulley transmission module 06 is connected with the other end of the pressure bearing module 05 through the steel wire rope 08 and is in a standby state. When it is necessary to move the clamping tongue 02, the pulley transmission module 06 is driven by pulling the steel wire rope 08 to drive the pressure bearing module 05. After being driven by the pulley transmission module 06, the pressure bearing module 05 starts to apply pressure to the clamping tongue base 03. The clamping tongue base 03 slides downward in the main body module 01 under the pressure applied by the pressure bearing module 05. The clamping tongue base 03 drives the clamping tongue 02 to move when it slides downward. In the process of the clamping tongue base 03 sliding downward, the reset spring 04 is compressed, and the reset spring 04 stores elastic potential energy at the same time of being compressed. When the steel wire rope 08 is released, the pulley transmission module 06 is reset, and the tension on the pressure bearing module 05 is released at the same time, the pressure applied by the pressure bearing module 05 to the clamping tongue base 03 disappears, and the reset spring 04 pushes the clamping tongue base 03 to move upward by using the elastic potential energy, and the limiting block 07 limits the clamping tongue base 03 to prevent the clamping tongue base 03 from moving out of the preset area.

[0063] The operator controls the clamping tongue base 03 and the clamping tongue 02 by pulling the steel wire rope 08 to drive the pulley transmission module 06 and the pressure bearing module 05. By using the principle of leverage to operate, the operator is more convenient, simple and labor-saving when operating the stacking buckle device. The modular design is adopted, and when the parts inside the device are damaged, the corresponding parts of the module can be replaced, reducing the maintenance cost and improving the maintenance efficiency. The reset spring 04 provides a reset function for the clamping tongue base 03, and ensures that the stacking buckle device can still maintain good performance after being used for many times, improving its reliability and stability.

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

[0065] The limiting block 07 is arranged on one side of the shell 012;

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

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

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

[0069] The fixing bolt 014 connects the upper cover 011 and the lower cover 013 with the shell 012 through the threaded through hole and the threaded hole.

[0070] The main body module 01 is composed of the upper cover 011, the shell 012, the lower cover 013 and the fixing bolt 014. The limiting block 07 is arranged on a predetermined side of the shell 012 to limit the movement range of the clamping 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 are aligned with the threaded through hole on the shell 012, and the fixing bolt 014 is used to pass through the threaded hole of the upper cover 011, the threaded through hole of the shell 012 and the threaded hole of the lower cover 013 in turn, so as to install the upper cover 011 and the lower cover 013 on the shell 012. The threaded connection ensures the stability of the connection between the upper cover 011, the shell 012 and the lower cover 013. When maintenance or inspection of the stacking buckle device is needed, the upper cover 011, the shell 012 and the lower cover 013 can be separated by unscrewing the fixing bolt 014, so that 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 the fixing bolt 014, ensuring the stability of the whole. It can be easily disassembled and assembled during maintenance. Standard threaded holes and threaded holes are adopted, so that the fixing bolt 014 can fix each part together, simplifying the installation process and improving the installation efficiency. The design of the upper cover 011, the shell 012 and the lower cover 013 is more efficient in space utilization than the traditional integrated stacking buckle device. The stacking buckle device provided by the scheme reduces the volume and weight of the stacking buckle device, making the device more convenient and flexible during installation and use.

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

[0073] The upper cover 011, the shell 012 and the lower cover 013 are connected by the fixing bolt 014, the limiting block 07 is arranged on one side of the shell 012, and is used for further limiting the movement range of the clamping tongue base 03. The upper cover 011 and the lower cover 013 are both provided with a preset limiting area for limiting the movement of the clamping tongue 02. The clamping tongue base 03 is installed on the lower cover 013, the clamping tongue 02 extends outward from both sides of the clamping tongue base 03 and passes through the limiting area 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 exert pressure on the clamping tongue base 03 by pulling the steel wire rope 08, the clamping tongue base 03 moves downward. The clamping tongue base 03 drives the clamping tongue 02 to move. The movement range of the clamping tongue 02 is limited by the limiting area on the upper cover 011 and the lower cover 013, ensuring that it moves within the predetermined range.

[0074] The limiting area of the upper cover 011 and the lower cover 013 limits the movement range of the clamping tongue 02, effectively preventing the clamping tongue 02 from exceeding the predetermined range during operation, reducing the risk of equipment damage caused by improper operation.

[0075] In an optional embodiment, the limiting block 07 further includes a reinforcing rib 071, one side of the reinforcing rib 071 is connected with the limiting block 07, and the other side is connected with the shell 012, for improving the supporting strength of the limiting block 07.

[0076] When the operator releases the steel wire rope 08, drives the pulley transmission module 06 and the pressure bearing module 05, and releases the pressure on the clamping tongue base 03, the reset spring 04 releases the stored elastic potential energy and pushes the clamping tongue base 03 to move upward. The clamping tongue base 03 will be limited by the limiting block 07 to ensure that the clamping tongue base 03 stops at the predetermined position. The reinforcing rib 071 plays a reinforcing role between the limiting block 07 and the shell 012, increasing the stability and support strength of the limiting block 07. When the clamping tongue base 03 is reset, the elastic potential energy released by the reset spring 04 will make the clamping tongue base 03 move quickly, causing a huge impact force. The reinforcing rib 071 can improve the support strength of the limiting block 07, effectively preventing the limiting block 07 from deforming or being damaged. The reinforcing rib 071 is connected with the limiting block 07 and the shell 012 by welding.

[0077] The reinforcing rib 071 provides stable support between the limiting block 07 and the shell 012, and by connecting the limiting block 07 and the shell 012, the support strength of the limiting block 07 is improved. This makes the stacked buckle device more stable when bearing the impact force of the clamping tongue base 03 reset, effectively preventing the limiting block 07 from deforming or being damaged, and prolonging the service life.

[0078] In an optional embodiment, the pressure bearing module 05 comprises: 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 predetermined 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 with the pressure bearing 051, and the other end is in abutment with the clamping tongue base 03;

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

[0082] The pressure bearing 051 is installed on the bearing support column 054, and the pressure rod 052 and the transmission rod 053 are connected on the pressure bearing 051. The transmission rod 053 is connected with the pulley transmission module 06 through the steel wire rope 08. When the operator pulls the steel wire rope 08, it will pass through the pulley transmission module 06, drive the transmission rod 053 to move, the transmission rod 053 drives the pressure bearing 051 to rotate, and the pressure bearing 051 drives the pressure rod 052 to exert pressure on the clamping tongue base 03 when rotating. The clamping tongue base 03 moves downward under the applied pressure.

[0083] The pressure bearing 051 is used as a main transmission component, and the pressure bearing 051 is in abutment with the latch tongue base 03 by connecting the pressure rod 052 and the transmission rod 053, so that the operator drives the transmission rod 053 by pulling the steel wire rope 08, and the purpose of labor saving is achieved by using the lever principle. The components in the pressure bearing module 05 are designed in a modular manner, so that the components are 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 cavity 061, an auxiliary pulley 062, and a pulley support column 063.

[0085] The pulley support column 063 is arranged at a predetermined 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 is connected with the auxiliary pulley 063 by passing through the inside of the spring cavity 061.

[0087] The steel wire rope 08 is connected with one end of the transmission rod 053 by passing through the auxiliary pulley 062, and 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 arranged on the second pulley support column 0632.

[0092] The steel wire rope 08 is connected with the transmission rod 053 by passing through the inside of the spring cavity 061, and then passing through the first auxiliary pulley 0621 and the second auxiliary pulley 0622 in sequence.

[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 steel wire rope 08 passes through the inside of the spring cavity 061, passes through the first auxiliary pulley 0631 and the second auxiliary pulley 032, and is connected with the transmission rod 053. The first auxiliary pulley 0621 and the second auxiliary pulley 0622 form a pulley set. When the operator pulls the steel wire rope 08, the steel wire rope 08 passes through the inside of the spring cavity 061, passes through the first auxiliary pulley 0621 and the second auxiliary pulley 0622, drives the transmission rod 053 to move, and the transmission rod 053 drives the pressure bearing 051 to rotate. When the pressure bearing 051 rotates, the pressure rod 052 drives the clamping tongue base 03 to exert pressure. After the clamping tongue base 03 is subjected to the applied pressure, it moves downward.

[0094] The pulley set formed by the first auxiliary pulley 0621 and the second auxiliary pulley 0622 can not only save labor but also change the direction of the force. By using the principle of leverage, the power arm is twice the resistance arm, so that the operator can control the movement of the buckle by using smaller force.

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

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

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

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

[0099] The steel wire spring 0612 inside the spring cavity 061 can effectively limit the pulling stroke when the operator pulls the steel wire rope 08, preventing 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, and releases the stored elastic potential energy when the steel wire rope 08 is released, helping the steel wire rope 08 to reset.

[0100] In an optional embodiment, a limiting key 081 is arranged on the steel wire rope 08, one end of the limiting key 081 is connected with the spring washer 0613;

[0101] A clamping groove corresponding to the limiting key 081 is arranged inside the cavity 0611;

[0102] When the steel wire rope 08 is pulled, the limiting key 081 drives the spring washer 0613 to apply pressure to the steel wire spring 0612, and the steel wire spring 0612 is compressed after being pressed. When the steel wire rope 08 is pulled to the preset position, rotating the steel wire rope 08 makes the limiting key 081 clamped into the clamping groove, so that the steel wire spring 0612 remains in the compressed state.

[0103] One end of the limiting key 081 is connected with the spring washer 0613. When the operator pulls the steel wire rope 08, the steel wire rope 08 starts to move, and the limiting key 081 on the steel wire rope 08 is driven to move, and the limiting key 081 drives the spring washer 0613 to pull the steel wire spring 0612, so that the steel wire spring 0612 is compressed, which limits the pulling stroke and stores elastic potential energy. When the steel wire rope 08 is pulled to the preset position, the operator can rotate the steel wire rope 08 to make the limiting key 081 clamped into the clamping groove of the cavity 0611. The limiting key 081 is clamped into the clamping groove, so that the steel wire spring 0612 remains in the compressed state. When the steel wire rope 08 needs to be loosened, the operator needs to rotate the steel wire rope 08 in the opposite direction to make the limiting key 081 leave the clamping groove, and then loosen the steel wire rope 08. After the steel wire rope 08 is loosened, the steel wire spring 0612 releases the elastic potential energy and drives the steel wire rope 08 to reset through the spring washer 0613.

[0104] Through the limiting key 081 and the clamping groove corresponding to the limiting key 081 arranged in the cavity 0611, the operator can pull the steel wire rope 08 to the preset position according to the working condition, and rotate the steel wire rope 08 to make the limiting key 081 clamped into the clamping groove, so that the steel wire rope 08 is locked at the preset position, and the steel wire spring 0612 remains in the compressed state. The steel wire spring 0612 stores elastic potential energy during compression, and releases the elastic potential energy when the steel wire rope 08 is loosened, which helps the steel wire rope 08 to reset quickly. The design of the limiting key 081 and the spring washer 0613 reduces the direct friction and wear between the steel wire rope 08 and the steel wire spring 0612, prolonging the service life of these components.

[0105] It is to be understood that the embodiments that have been described above are merely illustrative and that changes and modifications can be made to those embodiments without departing from the scope of the application. It is therefore intended to cover in the appended claims all such changes and modifications that are within the scope of these embodiments.
