[0005] To solve the above-mentioned first technical problem, the present application provides a screw mounting structure, comprising a screw, a spring and a second sleeve fixed to a first component, wherein the screw rod of the screw is rotatably arranged in the second sleeve to threadedly connect the first component with a second component below the first component, the spring is deformed under pressure when the screw is threadedly connected and provides upward rebound support for the screw, and a stopper is arranged in the second sleeve to stop the screw rod from being separated upward from the second sleeve.
[0006] The screw mounting structure facilitates detachable connection of component devices while preventing loss of screws.
[0007] Preferably, the screw head of the screw is downwardly extended with a first sleeve, and the inner wall surface of the first sleeve is in sleeve or separation with the outer wall surface of the second sleeve.
[0008] In a normal state, the screw rod, the second sleeve or the spring are all sealed and protected from moisture, which is beneficial to improve the service life of the screw mounting structure and the component device in a humid environment.
[0009] Preferably, the inner wall surface of the first sleeve is threadedly connected with the outer wall surface of the second sleeve after being sleeved.
[0010] The above-mentioned arrangement is more conducive to efficient control of the deformed state of the spring under pressure, thereby making the threadedly connection of the first component with the second component below the first component more reliable, the moisture-proof sealing effect better, and the rebound support force released by the spring when the deformed state under pressure is released stronger.

[0033] To make the above-mentioned objectives, technical solutions, and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only some embodiments constituting the present invention, and are only used to explain the present invention and do not constitute a limitation thereof. Unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other.
[0034] Example 1
[0035] like Figures 1-5 As shown, the present invention provides a screw mounting structure, including a screw 1, a spring 2, and a second sleeve 4 fixed to a first component 3. The screw 12 is rotatably inserted into the second sleeve 4 to thread the first component 3 to the second component below it. The spring 2 is compressed and deformed during the threaded connection and provides upward rebound support to the screw 1. The second sleeve 4 has a stop portion 41 for preventing the screw 12 from disengaging upward from the second sleeve 4.
[0036] Specifically, during the assembly of screw 1, the screw 12 is screwed downwards under external force, the spring 2 is compressed and deformed, and the first component 3 and the second component are threaded together. The spring 2 remains compressed and deformed after the external force is removed. Conversely, during the disassembly of screw 1, the screw 12 is screwed upwards under external force, the first component 3 and the second component are separated, the compressed and deformed spring 2 forces screw 1 to move upwards, and the stop part 41 blocks the upward movement of screw 1, ensuring that screw 12 does not detach from the second sleeve 4. Thus, the screw mounting structure described in this invention facilitates detachable connection of components and equipment while preventing screw loss.
[0037] Preferably, the screw head of the screw 1 extends downward to provide a first sleeve 11, and the inner wall surface of the first sleeve 11 is engaged with or separated from the outer wall surface of the second sleeve 4.
[0038] Specifically, under normal conditions, the first component 3 is threadedly connected to the second component below it. At this time, the inner wall of the first sleeve 11 will fit onto the outer wall of the second sleeve 4, thereby forming a moisture-proof seal for the screw 12, the second sleeve 4, or the spring 2, which is beneficial to improving the service life of the screw installation structure and its component equipment in humid environments.
[0039] Preferably, the inner wall surface of the first sleeve 11 and the outer wall surface of the second sleeve 4 are threaded together after fitting.
[0040] Specifically, the above arrangement is more conducive to efficient control of the compressed and deformed state of the spring 2, thereby not only making the threaded connection of the first member 3 and the second member below it more secure, but also better preventing moisture from entering, and in addition, the rebound support force released by the spring 2 when the compressed and deformed state is released can also be stronger.
[0041] Preferably, the spring 2 is sleeved on the outer wall surface of the screw rod 12 and is built in the first sleeve 11 and / or the second sleeve 4.
[0042] Specifically, when the spring 2 is built in the first sleeve 11, the spring 2 will be compressed and deformed from the lower end and directly provide upward rebound support to, for example, the screw head during the sleeving process of the first sleeve 11 and the second sleeve 4 or even the threaded connection process. When the spring 2 is built in the second sleeve 4, the spring 2 will be compressed and deformed from the upper end and directly provide upward rebound support to the screw rod 12 during the downward rotation and threading process of the screw rod 12. Of course, the spring 2 can also have two, one built in the first sleeve 11 and the other built in the second sleeve 4.
[0043] It should be noted here that the built-in form of the spring 2 is not particularly limited here, and it can be diversified according to needs and in combination with the specific structural shape of the screw rod 12, the spring 2, the first sleeve 11, and the second sleeve 4, for example:
[0044] As one of the preferred embodiments of the present application, when the spring 2 is built in the first sleeve 11, the upper end of the spring 2 is fixed to any one or more of the screw head, the screw rod 12, and the first sleeve 11, the lower end of the spring 2 is in abutment or separation with the second sleeve 4, and the stop form of the stop portion 41 is clamping limiting.
[0045] More specifically, the fixing of the upper end of the spring 2 can also include that the upper end of the spring 2 is supported in a clamping manner to the inner wall surface of the first sleeve 11, at this time, the spring 2 can also be irregular; and the lower end of the spring 2 can be in a suspended state or in a non-suspended state, thereby affecting whether the lower end of the spring 2 is partially or fully in abutment with the second sleeve 4, or the lower end of the spring 2 can also be indirectly in abutment with the second sleeve 4 through the sliding stopper provided in the first sleeve 11. Regardless of the setting form, when the first member 3 and the second member are separated, the spring 2 will strongly rebound upward, thereby forcing any one or more of the screw head, the screw rod 12 and the first sleeve 11 to move upward, and further driving the entire screw 1 (including the first sleeve 11) to move upward integrally, when the lower end of the screw rod 12, for example, the external thread part 121, moves upward to the stop portion 41, the stop portion 41 will form a clamping limit to the external thread part 121, unless the clamping limit is removed under the action of an external force much greater than the weight of the screw 1 (including the first sleeve 11). For another example, the second sleeve 4 can have a hollow top plate 44, the stop portion 41 can be an internal thread structure 441 provided in the hollow top plate 44, the thread part 121 can be strongly screwed into or out of the internal thread structure 441 under the action of an external force, but under the action of only the rebound force of the spring 2, the internal thread structure 441 will only form a clamping limit to the lower end of the screw rod 12, for example, the external thread part 121.
[0046] As another preferred embodiment of the present application, when the spring 2 is built in the second sleeve 4, the screw rod 12 has a boss part 122, the lower end of the boss part 122 is pressed on the spring 2, and the upper end of the boss part 122 is in abutment or separated from the stop portion 41.
[0047] More specifically, the lower end of the spring 2 can be in abutment with the inner wall surface of the second sleeve 4, or can be fixed to the inner wall surface of the second sleeve 4, or can also be in abutment or fixed to the first member 3 along the periphery of the first mounting hole 31; and the stop portion 41 can still be the hollow top plate 44 of the second sleeve 4. Among them, the boss part 122 is an organic part of the screw rod 12, the upper end of the spring 2 will directly provide upward rebound support to the boss part 122, i.e., the screw rod 12 after being deformed by the pressing of the boss part 122, and the specific stopping process will not be described in detail.
[0048] Preferably, the second sleeve 4 is fitted into the first mounting hole 31 of the first member 3 by riveting, and forms an anchor boss 42 and an opening 43 at the lower end surface of the first member 3.
[0049] Specifically, the second sleeve 4 is generally a metal piece to bear greater fatigue strength in frequent disassembly process, and the material of the first component 3 can be set according to specific needs. When the second sleeve 4 is fixed in the first mounting hole 31 in the form of riveting, the screw mounting structure of the application has a larger installation application range, and the assembly of the screw mounting structure of the application on the first component 3 is more convenient, and the opening of the aperture 42 can further ensure the riveting forming effect.
[0050] Preferably, the lower end surface of the first component 3 further extends downward to be provided with a first cover 32 located outside the anchoring boss 42, and the height of the first cover 32 is greater than the height of the anchoring boss 42.
[0051] Specifically, the first cover 32 can be used to protect the anchoring boss 42 and prevent the anchoring boss 42 from being worn to affect the riveting effect of the second sleeve 4 on the first component 3. When the first component 3 is threadedly connected with the second component below, the first cover 32 can also be embedded in the mounting groove of the second component to enhance the fastening effect and sealing effect of the threaded connection.
[0052] Embodiment 2
[0053] Referring to Figures 1-5 The application further provides a panel, which is the first component 3 and is provided with the screw mounting structure in embodiment 1.
[0054] Specifically, those skilled in the art can understand that, when the panel in embodiment 2 is the first component 3 and is provided with the screw mounting structure in embodiment 1, the solution to the technical problem and the technical effect can be obtained by referring to the description of the screw mounting structure in embodiment 1, which will not be repeated here.
[0055] The application further provides a water module provided with the panel in the embodiment.
[0056] The application further provides an air source heat pump provided with the panel in the embodiment.
[0057] Specifically, those skilled in the art can also understand that, when the water module and / or the air source heat pump in embodiment 2 are provided with the panel in the embodiment, the solution to the technical problem and the technical effect can still be obtained by referring to the description of the screw mounting structure in embodiment 1, which will not be repeated here.
