Detailed Description
In order to make the aforementioned objects, technical solutions and advantages of the present invention more comprehensible, the present invention is described in further detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only some of the embodiments constituting the present invention, and are not intended to limit the present invention, and the embodiments and features of the embodiments may be combined with each other without conflict.
Example 1
As shown in fig. 1 to 5, the present invention provides a screw mounting structure, including a screw 1, a spring 2, and a second sleeve 4 fixedly connected to a first member 3, wherein a screw 12 of the screw 1 is rotatably inserted into the second sleeve 4 to threadedly connect the first member 3 with a second member below the first member, the spring 2 is deformed by pressure during the threaded connection and provides upward resilient support for the screw 1, and a stopper 41 is opened in the second sleeve 4 for stopping the screw 12 from being separated upward from the second sleeve 4.
Specifically, in the process of assembling the screw 1, the screw 12 is screwed downwards under the action of external force, the spring 2 is pressed and deformed, the first member 3 and the second member are in threaded connection, and the spring 2 still keeps a pressed and deformed state after the external force is removed; conversely, during the process of detaching the screw 1, the screw 12 is screwed out upwards under the action of external force, the first member 3 is separated from the second member, the screw 1 is forced to move upwards by the compression-deformed spring 2, and the stop 41 stops the upward movement of the screw 1 to ensure that the screw 12 cannot be disengaged upwards from the second sleeve 4. Therefore, the screw mounting structure provided by the utility model is convenient for detachably connecting component equipment and can prevent the loss of screws.
Preferably, a first sleeve 11 extends downwards from the head of the screw 1, 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.
Specifically, in a conventional state, the first member 3 is in threaded connection with the second member below the first member, and at the moment, the inner wall surface of the first sleeve 11 is sleeved on the outer wall surface of the second sleeve 4, so that the screw 12, the second sleeve 4 or the spring 2 are protected from moisture, and the service life of the screw mounting structure and the member equipment thereof in a humid environment is prolonged.
Preferably, the inner wall surface of the first sleeve 11 is screwed with the outer wall surface of the second sleeve 4 after being fitted.
Specifically, the arrangement described above is more advantageous for efficiently controlling the compression deformation state of the spring 2, so that the threaded connection between the first member 3 and the second member therebelow is more secure, the moisture-proof sealing effect is better, and the resilient support force released by the spring 2 when the compression deformation state is released can be stronger.
Preferably, the spring 2 is sleeved on the outer wall surface of the screw 12 and is embedded in the first sleeve 11 and/or the second sleeve 4.
Specifically, when the spring 2 is embedded in the first sleeve 11, the spring 2 may be deformed under pressure from the lower end and directly provide upward resilient support for, for example, a screw during the process of engaging the first sleeve 11 with the second sleeve 4 or even during the process of screwing. When the spring 2 is arranged in the second sleeve 4, the screw 12 is pressed and deformed from the upper end and directly provides upward springback support for the screw 12 in the downward rotating penetrating process and even the threaded connection process. Of course, the spring 2 can also have two, one built into the first sleeve 11 and the other built into the second sleeve 4.
It should be further noted that the present invention is not limited to the built-in form of the spring 2, and the built-in form can be variously configured according to the needs and in combination with the specific structural shapes of the screw 12, the spring 2, the first sleeve 11, and the second sleeve 4, for example:
as one preferred embodiment of the present invention, when the spring 2 is embedded in the first sleeve 11, the upper end of the spring 2 is fixedly connected to any one or more of the screw head, the screw 12, and the first sleeve 11, the lower end of the spring 2 is abutted to or separated from the second sleeve 4, and the stopping manner of the stopping portion 41 is a snap-in limiting.
More specifically, the fixing of the upper end of the spring 2 may also include that the upper end of the spring 2 is internally supported on the inner wall surface of the first sleeve 11 in a clamping manner, and at this time, the spring 2 may also be irregular; the lower end of the spring 2 may be in a suspended state or an unsuspended state, so that whether the lower end of the spring 2 is partially or completely abutted against the second sleeve 4 can be influenced, or the lower end of the spring 2 can be indirectly abutted against the second sleeve 4 through a sliding baffle plate arranged in the first sleeve 11. Regardless of the arrangement, after the first member 3 and the second member are separated, the spring 2 will rebound upwards with a strong force, so as to force any one or more of the screw head, the screw 12, and the first sleeve 11 to move upwards, and further drive the whole screw 1 (including the first sleeve 11) to move upwards integrally, and when the lower end of the screw 12, such as the external thread portion 121, moves upwards to the stop portion 41, the stop portion 41 will form a clamping limit for the external thread portion 121, unless the clamping limit is released under the action of an external force much larger than the weight of the screw 1 (including the first sleeve 11). For another example, the second sleeve 4 may have a hollow top plate 44, the stopping portion 41 may be an internal thread structure 441 formed in the hollow top plate 44, the thread portion 121 may be screwed into or out of the internal thread structure 441 by an external force, but the internal thread structure 441 only forms a snap-fit limit for the lower end of the screw 12, for example, the external thread portion 121, by a strong resilient force of the spring 2.
In another preferred embodiment of the present invention, when the spring 2 is built in the second sleeve 4, the screw 12 has a boss portion 122, a lower end of the boss portion 122 is pressed against the spring 2, and an upper end of the boss portion 122 is brought into contact with or separated from the stopper portion 41.
More specifically, the lower end of the spring 2 may abut against the lower edge of the second sleeve 4, may be fixedly connected to the inner wall of the second sleeve 4, or may abut against or be fixedly connected to the first member 3 along the periphery of the first mounting hole 31; while stop 41 may still be the hollow top plate 44 of second sleeve 4. The boss portion 122 serves as an organic component of the screw 12, and the upper end of the spring 2 directly provides upward springback support for the boss portion 122, that is, the screw 12, after being pressed and deformed by the boss portion 122, and the specific stopping process is not described in detail.
Preferably, the second sleeve 4 is interference fitted into the first mounting hole 31 of the first member 3 by riveting, and forms an anchoring abutment 42 and a notch 43 at the lower end face of the first member 3.
Specifically, the second sleeve 4 is usually made of metal to bear more fatigue strength during frequent disassembling, and the material of the first member 3 can be set according to specific requirements. When the second sleeve 4 is fixedly connected in the first mounting hole 31 in a riveting manner, firstly, the screw mounting structure of the utility model has a wider mounting application range, and secondly, the screw mounting structure of the utility model is more convenient to assemble and mold on the first member 3, wherein the opening 42 can ensure the riveting and molding effect.
Preferably, the lower end surface of the first member 3 is further provided with a first housing 32 extending downwards and located at the periphery of the anchoring pier head 42, and the height of the first housing 32 is greater than that of the anchoring pier head 42.
Specifically, the first housing 32 can be used for protecting the anchoring pier 42, and preventing the anchoring pier 42 from being worn to affect the riveting effect of the second sleeve 4 on the first member 3; meanwhile, when the first member 3 is in threaded connection with the second member below the first member, the first housing 32 can be embedded into the mounting groove of the second member, so that the fastening effect and the sealing effect of the threaded connection are enhanced.
