Description
本發明涉及一種螺絲組件。The invention relates to a screw assembly.
螺絲是工業生產中最常用的一種緊固件，在扭動螺絲固定物件的過程中，如果用力過大便容易造成被固定物件的損壞。特別是在精密儀器的組裝過程中，例如將電子設備主機板固定在電子設備外殼時，如果用力稍大則有可能造成主機板的損壞，造成生產原料的浪費，降低工業生產的效率。此外，如果電子設備一旦不小心被摔或被撞，元件極易受到損害從而造成不可恢復的損失。Screws are the most commonly used fasteners in industrial production. In the process of twisting screws to fix objects, if the force is too large, it will easily cause damage to the fixed objects. Especially in the assembly process of precision instruments, for example, when the electronic device motherboard is fixed in the outer casing of the electronic device, if the force is slightly increased, the motherboard may be damaged, resulting in waste of production materials and reducing the efficiency of industrial production. In addition, if the electronic device is accidentally dropped or bumped, the component is extremely vulnerable and causes irreparable damage.
有鑒於此，有必要提供一種螺絲組件。In view of this, it is necessary to provide a screw assembly.
一種螺絲組件，包括一螺紋柱、一端頭以及一彈性件，所述螺紋柱包括一表面設有螺紋的柱體以及一設置於所述柱體一端的螺絲頭，所述螺絲頭的一自由端部上設有與一螺絲刀的端部配合的螺絲槽。所述端頭用於在裝配時抵擋於一與所述螺紋柱相配合的螺紋孔之外。所述彈性件包括一第一通孔，所述彈性件的一端藉由該第一通孔套接在所述螺絲頭上並與螺絲頭固定連接，另一端與所述端頭固定連接。所述端頭的中部開設有一與所述第一通孔以及所述螺絲槽相對的第二通孔，用於供一螺絲刀穿過。A screw assembly includes a threaded post, an end cap and an elastic member, the threaded post including a cylindrical body having a thread on the surface and a screw head disposed at one end of the cylindrical body, a free end of the screw head A screw groove is provided on the portion to cooperate with the end of a screwdriver. The tip is adapted to withstand a threaded bore that mates with the threaded post during assembly. The elastic member includes a first through hole, and one end of the elastic member is sleeved on the screw head and fixedly connected to the screw head, and the other end is fixedly connected to the end. A second through hole is formed in the middle of the end portion opposite to the first through hole and the screw slot for a screwdriver to pass through.
在使用本發明的螺絲組件固定物件時，螺紋柱在受力旋進螺紋孔的過程中不斷地對彈性件產生向下的拉力，使得彈性件逐漸處於拉伸狀態而產生向上的彈力，用於抵消扭動螺絲頭過程中產生的部分壓力，從而有效的防止壓力過大對被固定物件造成損壞，且本發明的彈性結構還能起到緩衝作用，防止物件摔落造成損壞。When the object assembly is fixed by using the screw assembly of the present invention, the threaded column continuously exerts a downward pulling force on the elastic member during the process of being screwed into the threaded hole, so that the elastic member is gradually stretched to generate an upward elastic force for The partial pressure generated during the twisting of the screw head is offset, thereby effectively preventing the excessive pressure from causing damage to the fixed object, and the elastic structure of the present invention can also serve as a buffering function to prevent the object from falling and causing damage.
