Abstract
A slotted expansion bolt comprises a screw cylinder, an expansion sleeve, a gasket and a washer and is characterized in that the expansion sleeve is sleeved on the screw cylinder and integrated with the screw cylinder, the gasket and the washer are sleeved on the outer wall of the screw cylinder forwards and backwards in one step, and the top end of a lead screw at the rear portion of the screw cylinder is further provided with a slot in the shape of a Chinese character 'yi'. The slotted expansion bolt can ensure pre-tightness and can perform secondary fastening, and a relevant device can be replaced under the condition that processing strength is not influenced.
Description
Technical field
The utility model relates to five metals class fastener areas, is specially a kind of EXPANSION ANCHOR BOLTS of opening straight groove.
Background technique
At present; The use of expansible anchor of metal is very general; Common form mainly is made up of the screw bolt and nut of an expansion tube and an end band cone; Its working principle is that bolt and the interaction between the expansion tube through the band cone produces relative displacement, and expansion tube is expanded, and is fixed on the position such as body of wall.
Yet common EXPANSION ANCHOR BOLTS is when expanding, and not tight phenomenon possibly occur expanding; Make nut drive the bolt rotation, cause EXPANSION ANCHOR BOLTS to change, tear loose nut in this case open; Even just pine little by little also can be caused the rotation of whole EXPANSION ANCHOR BOLTS, and is consequently tightly also tightly or not; Pine yet pine does not go out, and this phenomenon is vibrated at some and showed particularly outstandingly on the tangible equipment.
The model utility content
The technical problem that the utility model solved is to provide a kind of belt conveyer to use scraping plate mechanism, to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solved adopts following technological scheme to realize:
Open the EXPANSION ANCHOR BOLTS of straight groove; Comprise screw rod cylinder, expansion sleeve, pad and packing ring; Wherein expansion sleeve is enclosed within on the screw rod cylinder; And be connected as a single entity with the screw rod cylinder, pad and packing ring once are sleeved on the outer wall of screw rod cylinder after by forward direction, and the screw mandrel top at the rear portion of screw rod cylinder also should have one one word groove.
Beneficial effect:The utility model has been compared four advantages with common EXPANSION ANCHOR BOLTS:
1. the expansion that can guarantee EXPANSION ANCHOR BOLTS 100% is tight;
2. after use, vibrating its nut loosening of a little bigger place a little can be fastening again;
3. can need the more nut of exchange device taking-up EXPANSION ANCHOR BOLTS, be convenient to more exchange device;
4. easy processing does not need many consume materials, does not influence original intensity.
Description of drawings
Fig. 1 is the schematic representation of the utility model preferred embodiment.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
In the preferred embodiment referring to the EXPANSION ANCHOR BOLTS of opening straight groove of Fig. 1, comprise screw rod cylinder 2, expansion sleeve 1, pad 3, nut 4 and packing ring 5, wherein, screw rod cylinder 2 tops have a straight groove.
When expanding or dismantling its nut 4, cooperate the screw rod cylinder 2 that withstands fluting with a word bottle opener in addition in fastening its nut 4, can guarantee that screw rod can be with its nut 4 rotations with spanner.
More than show and described the advantage of basic principle, major character and the utility model of the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
Claims (1)
1. open the EXPANSION ANCHOR BOLTS of straight groove; Comprise screw rod cylinder, expansion sleeve, pad and packing ring; It is characterized in that expansion sleeve is enclosed within on the screw rod cylinder, and be connected as a single entity with the screw rod cylinder; Pad and packing ring once are sleeved on the outer wall of screw rod cylinder after by forward direction, and the screw mandrel top at the rear portion of screw rod cylinder also should have one one word groove.
