Description
Technical Field
[0001] The utility model belongs to the technical field of HVAC assemblies, and in particular relates to an anti-falling buckle spring fixing structure. Background Art
[0002] HVAC (Heating, Ventilation, and Air Conditioning) systems, or HVAC systems, are essential components of buildings for controlling indoor temperature, humidity, and air quality. In HVAC systems, clip springs are a common connector used to secure and connect various components, such as ducts, pipes, fittings, and other accessories. Their primary function is to provide a quick and reliable connection, ensuring the system's airtightness and structural integrity.
[0003] Currently, there are many ways to connect and fix the clip springs in the automotive HVAC assembly. However, the clip springs are difficult to remove after installation and require staff to use tools to remove them. Moreover, after the clip springs are removed, they are easy to fall into the gaps between other parts in the car because they are small. As a result, if the clip springs accidentally fall, they are difficult to remove.
[0004] To this end, we propose an anti-falling buckle spring fixing structure to solve the above problem. Summary of the Invention
[0005] The purpose of the utility model is to solve the problems in the prior art and to propose an anti-falling buckle spring fixing structure.
[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] Preferably, the buckle spring includes an arc-shaped rod, a hook rod and a handle, the bottom wall of the arc-shaped rod is against the top wall of the first limiting column and the top wall of the second limiting column, the hook rod is fixedly connected to one end of the arc-shaped rod, the side wall of the hook rod is against the side wall of the first limiting column, and the handle is fixedly connected to one end of the arc-shaped rod away from the hook rod.
[0009] Preferably, the length of the handle is greater than half the width of the second limiting groove, and both sides of the handle do not contact the inner walls of both sides of the second limiting groove.
[0010] Preferably, the fastening assembly includes a barrier rod, a rotating rod and a torsion spring. The side walls on both sides of the second limiting groove are provided with grooves. The two ends of the barrier rod are respectively located in the two grooves. The bottom wall of the barrier rod is abutted against the top wall of the handle. The rotating rod is fixedly connected to the side wall of one end of the barrier rod. The side wall of the second limiting groove is provided with two rotating grooves. The two ends of the rotating rod are respectively rotatably connected to the inner walls of the two rotating grooves. The torsion spring is wrapped around the outside of the rotating rod.
[0011] Preferably, the end of the blocking rod fixedly connected to the rotating rod is designed to be arc-shaped, and the depth of the groove is greater than the rotation radius of the end of the blocking rod fixedly connected to the rotating rod.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0023] like Figure 1 - Figure 6 As shown, an anti-fall-off spring fixing structure includes a shell 1 and a shell 2. The side wall of the shell 1 is fixedly connected with a plurality of first limiting grooves 3, and each first limiting groove 3 is fixedly connected with a first limiting column 4. At the corresponding positions of the shell 2, a plurality of second limiting grooves 5 are also fixedly connected, and each second limiting groove 5 is fixedly connected with a second limiting column 6. The size of the first limiting groove 3 is consistent with that of the second limiting groove 5, and the size of the first limiting column 4 is also consistent with that of the second limiting column 6. When the shell 1 and the shell 2 are buckled together, the first limiting groove 3 and the second limiting groove 5 can also be buckled together in correspondence.
[0024] A buckle spring is installed above the first limit column 4 and the second limit column 6. The buckle spring includes an arc rod 7, a hook rod 8 and a handle 9. The bottom wall of the arc rod 7 is against the top wall of the first limit column 4 and the top wall of the second limit column 6. The hook rod 8 is fixedly connected to one end of the arc rod 7. The side wall of the hook rod 8 is against the side wall of the first limit column 4. The handle 9 is fixedly connected to the end of the arc rod 7 away from the hook rod 8. The length of the handle 9 is greater than half the width of the second limit groove 5. Both sides of the handle 9 do not contact the inner walls on both sides of the second limit groove 5. When the staff needs to remove the buckle spring, the staff needs to lift up the handle 9.
[0025] A fastening assembly for clamping the fastening spring position is installed in the second limiting groove 5, and the fastening assembly includes a blocking rod 10, a rotating rod 11 and a torsion spring 12. Grooves 13 are provided on both side walls of the second limiting groove 5. The two ends of the blocking rod 10 are respectively in the two grooves 13. The bottom wall of the blocking rod 10 is against the top wall of the handle 9. The rotating rod 11 is fixedly connected to the side wall of one end of the blocking rod 10. The end at which the blocking rod 10 and the rotating rod 11 are fixedly connected is an arc-shaped design. The depth of the groove 13 is greater than the rotation radius of the end at which the blocking rod 10 and the rotating rod 11 are fixedly connected. The existence of the groove 13 will not affect the rotation of the blocking rod 10.
[0026] Two rotating grooves 14 are provided on the side wall of the second limiting groove 5. The two ends of the rotating rod 11 are rotatably connected to the inner walls of the two rotating grooves 14 respectively. The torsion spring 12 is wrapped around the outside of the rotating rod 11. The force applied to the rotating rod 11 by the torsion spring 12 will cause the rotating rod 11 to have a tendency to drive the blocking rod 10 to move toward the direction of the groove 13.
[0027] The working principle is as follows: first, install the buckle spring on the first limiting column 4, then assemble the housing 1 1 and the housing 2 2 together, then rotate the blocking rod 10 so that one end of the blocking rod 10 leaves the groove 13, and finally, buckle the buckle spring with the second limiting column 6 to lock the housing 1 1 and the housing 2 2;
[0028] When disassembly is required, the staff needs to first rotate the blocking rod 10 so that the blocking rod 10 rotates around the rotating rod 11, compressing the torsion spring 12 while making the blocking rod 10 leave the groove 13, and then the buckle spring can be disassembled through the handle 9. At this time, the buckle spring is separated from the second limiting column 6, and the shell 1 1 and the shell 2 2 can be separated and disassembled. The first limiting column 4 and the hook rod 8 can ensure that the buckle spring is connected to the first limiting column 4 due to the presence of the arc rod 7, thereby preventing the buckle spring from falling into the gap of other automobile parts after disassembly and being lost and difficult to remove.
[0029] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
