Abstract
The utility model relates to a kind of slide system setscrew, comprise expansion sleeve, the expansion plug with sleeve part and bulge, described bulge forms expansion pawl by otch and tube wall between the incisions and forms, wherein, described expansion plug is provided with the tenon corresponding with expansion sleeve notch quantity and position, when expansion plug is inserted in expansion sleeve, each tenon embeds in each otch.The utility model has the advantage of the idle running overcoming setscrew from structure, structure be simpler, assemble more convenient.
Description
Technical field
The utility model relates to a kind of slide system setscrew.
Background technique
The applicant discloses a kind of high tensile strength setscrew in application number 201320773544.2, comprise metal bolts, sleeve, pad and lock nut, described sleeve comprises sleeve part and bulge, described bulge forms expansion pawl by otch and tube wall between the incisions and forms, described metal bolts at least comprises screw section and expansion piston part, described expansion piston part is a plug-like end, the screw section of described metal bolts penetrates from the bulge of sleeve, through described sleeve, attachment spacers successively at least again, lock nut and turnbuckle, the length that described metal bolts removes expansion piston part is greater than described sleeve, pad and lock nut thickness sum.
In use, when the screw section of described metal bolts penetrates from the bulge of sleeve, through described sleeve, at least more successively after attachment spacers, lock nut and internal thread sleeve pipe (turnbuckle), need to do a pinching action to lock nut and internal thread sleeve pipe, prevent lock nut and turnbuckle from getting loose, then entirety is knocked in embedded hole.But this structure defectiveness, does not expand or turnbuckle slide fastener once discovery bulge, needs overall pulling down.
Through claimant's use of nearly a year, find that this setscrew at least also has following deficiency: the part of (1) setscrew is more, cost is comparatively large, installs loaded down with trivial details; (2) need between former lock nut and sleeve pipe to compress, this step wastes time and energy; (3) part nonfunctional.
Claimant's application number 201420348400.7 discloses the another kind of setscrew for high tensile strength for this reason, for furred ceiling, be made up of expansion sleeve and metal bolts, described expansion sleeve comprises sleeve part and bulge, and described bulge forms expansion pawl by otch and tube wall between the incisions and forms; Described metal bolts comprises screw section and expansion piston part, and described expansion piston part is a plug-like end, and wherein, screw section is stretched out from expansion sleeve and is connected with inner screw sheath pipe thread.Decrease pad and lock nut two parts install, dismantle more convenient, and in order to prevent idle running, the setscrew outer cladding one deck plastic film assembled, this structure can the expansion status of intuitive judgment setscrew, and metal bolts length can be shortened, thus weight reduction, to reduce costs.
In use, there is the idle running situation between expansion sleeve and expansion plug in said structure, is unfavorable for that bulge expands sometimes.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of slide system setscrew, overcomes the idle running between expansion sleeve and expansion plug from structure.
The utility model solves idle running problem by following technical proposals: a kind of slide system setscrew, comprise expansion sleeve, the expansion plug with sleeve part and bulge, described bulge forms expansion pawl by otch and tube wall between the incisions and forms, wherein, described expansion plug is provided with the tenon corresponding with expansion sleeve notch quantity and position, when expansion plug is inserted in expansion sleeve, each tenon embeds in each otch.This structure effectively can prevent the idle running between expansion plug and expansion sleeve.The setting of this structure no longer needs, at setscrew outer cladding film, to assemble simpler.
On such scheme basis, the sleeve part of described expansion sleeve has multiple projection.The protruding idle running that can prevent expansion sleeve.
On such scheme basis, described expansion sleeve otch is 3 ~ 4, and the tenon quantity on expansion plug is consistent with otch or have the tenon of two positional symmetry at least.
Superiority of the present utility model is: the idle running overcoming setscrew from structure, and structure is simpler, it is more convenient to assemble.

Embodiment
Incorporated by reference to Figure of description, the utility model is further illustrated.
Shown in expansion sleeve schematic diagram as of the present utility model in accompanying drawing 1 and accompanying drawing 2 expansion plug schematic diagram of the present utility model:
A kind of slide system setscrew, comprise expansion sleeve 1, the expansion plug 2 with sleeve part 11 and bulge 12, described bulge 12 forms expansion pawl by otch 13 and tube wall between the incisions and forms, for there being the expansion sleeve of four otch in the present embodiment, namely this expansion sleeve 1 has four otch 131,132,133,134 on bulge 12, and these four otch 131,132,133,134 define four expansion pawls 141,142,142,144.
Described expansion plug 2 is provided with the tenon 21 corresponding with expansion sleeve notch quantity and position, and when expansion plug 2 is inserted in expansion sleeve 1 with one end of tenon 21, each tenon 21 embeds in each otch, and expansion plug 2 can be prevented relative to the idle running of expansion sleeve 1.In accompanying drawing 2, the expansion plug 2 of display is the tenon of two positional symmetry, can embed otch 131 and otch 133; Or these two tenons embed otch 132 and otch 134.Also can use the expansion plug with four tenons, then these four tenons need corresponding with the position of the otch of expansion sleeve.
Specifically, described expansion plug outside is one is round table-like plug shaped article, and described tenon is positioned at the taper end of plug shaped article, and expansion plug is filled in expansion sleeve by its taper end.
If the expansion sleeve of the present embodiment there are three otch, then the tenon corresponding position on corresponding expansion plug also has three corresponding tenons.
The sleeve part 11 of described expansion sleeve 1 has multiple protruding 15, and when expansion sleeve is inserted after in outside matrix, this projection 15 can prevent expansion sleeve 1 relative to the idle running of outside matrix.
In addition, described expansion sleeve 1 inwall (not shown) and the inwall of expansion plug 2 all have screw section 22, can have metal bolts through expansion sleeve and expansion plug.
