Abstract
The utility model provides a captive screw capable of rebounding. The captive screw capable of rebounding structurally comprises a screw body 1, a spring 2, a spring accommodating cavity 3, an internal thread step hole 4, a screw base 5 and an installation member. The screw base 5 is installed on the installation member 6 through a certain installation mode, the spring 2 is placed in the spring accommodating cavity 3 of the spring 2 of the screw base 5, and the screw body 1 is screwed in the internal thread step hole 4 of the screw base 5 through the spring 2. The captive screw capable of rebounding has the advantage that after the installation member is disassembled, the screw body cannot drop; the fact that a protrusion does not exist on the installation end face of the installation member is guaranteed, and assembly is convenient; after the installation member is assembled, the screw body is screwed up and stressed by threaded pressure and elastic force of the spring so as to enable the screw body not to prone to loosen; and the screw body and the spring are convenient to disassemble.
Description
Technical field
The utility model relates to a kind of captive screw that rebounds, its structure is that screw basement, spring and screw are formed.In assembling set dismounting, installation process, do not worry that toner screw can not find, easy to use.General installation or the housing assembling that is used for structural member, module product and cabinet product.
Background technique
The installation of structural member, module product or cabinet product or housing assembling major part are that active screw is installed on the market now, but when product maintenance or replacing, because operator not careful causes losing of screw easily, gently then needing to reconfigure screw installs, heavy then screw lost to the inner short circuit that forms of product damage product, cause heavy economic losses or casualties.The installation of computer casing also has some captive screw on the market, but its structure is comparatively simple, and only is fit to the shell installation of cabinet.When cabinet and equipment installation, the attachment face that often needs product is flat, does not have bump, and general computer does not satisfy demand with captive screw.Also have a kind of captive screw of collar formula, screw is blocked by collar at attachment face, and to realize that screw does not come off, if still screw in use damages, its replacing and inconvenience thereof need special-purpose instrument.Above-mentioned two kinds of captive screw can satisfy pine and adeciduate function, but not to be to use scope narrower be exactly that dismounting is inconvenient for it, and the present invention is directed to mainly is to propose improvement at these 2.
Summary of the invention
The utility model proposes a kind of captive screw that rebounds, its purpose is intended to overcome the above-mentioned defective of existing in prior technology, when making the assembling set installation or removal, is convenient to the assembling of product, make product the mounting screw difficult drop-off, lose.
Technical solution of the present utility model: it is characterized in that comprising screw, spring, spring receiving cavity, internal thread step hole, screw basement, assembling set, wherein screw basement is installed on the assembling set by certain mounting type, then spring is put into the spring receiving cavity of the spring of screw basement, and screw is screwed in the internal thread step hole of screw basement by spring.
Good effect of the present utility model: 1) after the assembling set dismounting, screw does not come off; 2) the installation end face of assurance assembling set does not have bump, is convenient to assembling; 3) after the assembling set assembling, screw is subjected to also being subjected to spring force the screw thread pressure except tightening, and makes that screw is difficult for getting loose; 4) screw and spring are for convenience detach.
Description of drawings
Accompanying drawing 1 is the structural representation of captive screw of can rebounding.
Among the figure 1 is screw, the 2nd, spring, the 3rd, spring receiving cavity, the 4th, internal thread step hole, the 5th, screw basement, the 6th, assembling set.
Embodiment
The screw front end of described screw 1 is external thread structure, and intermediate section is the cylinder polished rod, and screw cap is interior hexagonal or cross coiled hair or a letter disk capitiform formula.
Described spring 2 need be in compressive state under the state that assembling set is not installed, guarantee that screw 1 is subjected to spring force and is stuck in the spring receiving cavity 3.
Described spring receiving cavity 3 should have the spring of holding cavity and internal thread step hole 4.When assembling set 6 was installed, the pressure that spring 2 can be subjected to screw 1 was retracted in the spring receiving cavity 3 of screw basement 5; When not adorning assembling set, screw 1 can be subjected to the elastic force of spring, but its screw thread can not be stuck in the screw basement screw directly by the internal thread step hole of screw basement.
During work, the captive screw pedestal is installed to (generally by welding, rivet, be threaded or screw basement and assembling set one being processed) on the assembling set that needs to fix, then spring and screw are installed on the screw basement, realize by screw on the fixing corresponding structural member of assembling set; When assembling set was installed, the pressure that spring can be subjected to screw was retracted in the cavity that holds spring of spring pedestal; When not adorning assembling set, screw can be subjected to the elastic force of spring, but its screw thread can not be stuck in the screw basement screw directly by the internal thread step hole of screw basement.If in use, the infringement of screw or spring appears, screw can be screwed out, take off spring, with the part exchanging of corresponding infringement, the new fit on of laying equal stress on.
Claims (3)
1. captive screw can rebound, it is characterized in that comprising screw, spring, spring receiving cavity, internal thread step hole, screw basement, assembling set, wherein screw basement is installed on the assembling set by certain mounting type, then spring is put into the spring receiving cavity of the spring of screw basement, and screw is screwed in the internal thread step hole of screw basement by spring.
2. the captive screw that rebounds according to claim 1, the screw front end that it is characterized in that described screw is external thread structure, and intermediate section is the cylinder polished rod, and the form of screw cap is interior hexagonal or cross coiled hair or a letter disk head.
3. the captive screw that rebounds according to claim 1 is characterized in that described screw is stuck in the spring receiving cavity or is stuck in the screw basement.
