Abstract
The invention relates to a single-side slotted-type bushing, which comprises a bushing main body (1), wherein one end of the bushing main body (1) is connected with a nut or a screw cap, the bushing main body (1) is provided with a long groove (2), and the long groove (2) forms an opening on one end of the bushing main body (1) so as to be convenient for leading out a wiring harness which is connected with the nut or the screw cap. Since the bushing main body is provided with the long groove, and the long groove can be convenient for leading out the wiring harness which is connected with the nut or the screw cap, even though under the situation of a narrow space, the nut or the screw cap can be still disassembled from the bushing without being influenced by the wiring harness.
Description
Technical field
The present invention relates to a kind of one-sided slotted sleeve, especially relate to a kind of one-sided slotted sleeve for automotive oxygen sensor.
Background technology
In automobile manufacturing process, the connection of screw thread pair is one of main type of attachment realizing auto parts and components assembling.Between screw thread pair, the guarantee of moment uses open-end wrench, box spanner to realize more.Open-end wrench is mainly used in the more abundant link position of nut end or the fastening space of bolt end.Box spanner is mainly used in nut end or bolt end completely lower than being connected face, and the diameter of shrinkage pool can not be used for spanner of slotting, and is specially adapted to twist bolt or the nut of the very narrow and small or very depths of caving in, position.Be exactly bolt part space constraint in addition, also can only improve with box spanner and tighten operating efficiency.
Summary of the invention
The present invention devises a kind of one-sided slotted sleeve, its technical problem solved is that (1) lambda sensor and ternary catalyzing unit link position space are little, use open-end wrench can not Quick fastening, cause open-end wrench rotating distance little due to space constraint and easily touch hand in fastener cycle; (2) lambda sensor rear end is with lambda sensor wire harness, and when using normal sleeve fastening, wire harness does not have enough placement spaces, and the normal sleeve of standard can not be used to carry out fastening.
In order to solve the technical problem of above-mentioned existence, present invention employs following scheme:
A kind of one-sided slotted sleeve, comprise sleeve body (1), one end of sleeve body (1) is connected with nut or nut, sleeve body (1) has elongated slot (2), and described elongated slot (2) forms opening and draws to facilitate the wire harness be connected with nut or nut in described sleeve body (1) one end.
Further, described sleeve body (1) other end is spanner link (3).
Further, described spanner link (3) is provided with driving end and connects spacing hole (4), and when key adaptor inserts from sleeve upper ejector lever link (3), key adaptor upper limit ball snaps in described driving end and connects in spacing hole (4).
Further, described elongated slot (2) opening part have lead angle (5) be convenient to wire harness import.
Further, described elongated slot (2) is axially arranged in parallel with sleeve body (1).
Further, sleeve body (1) material is stainless steel.
A kind of for lambda sensor method for dismounting, described one-sided slotted sleeve is socketed in the flange face end that lambda sensor carries, lambda sensor wire harness is passed in described elongated slot (2), box spanner turns clockwise and drives lambda sensor and oxygen sensing wire harness synchronous rotary, when screw thread pair reaches moment between lambda sensor and ternary catalyzing unit, take off box spanner.
This one-sided slotted sleeve, compared with ordinary cartridge, has following beneficial effect:
(1) the present invention owing to having elongated slot in sleeve body, and this elongated slot can conveniently be drawn with nut or bolt rat tail, even if when narrow space, nut or bolt still can unload by sleeve, and not by the impact of its wire harness.
(2) the elongated slot opening part of the present invention on sleeve is provided with lead angle, and this lead angle can facilitate entering of wire harness, and can not cause wearing and tearing to wire harness.
Accompanying drawing explanation
Fig. 1: the structural representation of the one-sided slotted sleeve of the present invention;
The right view of Fig. 2: Fig. 1.
Description of reference numerals:
1-sleeve body; 2-elongated slot; 3-spanner link; 4-driving end connects spacing hole; 5-lead angle; 6-opening.
Detailed description of the invention
Below in conjunction with Fig. 1 and Fig. 2, the present invention will be further described:
A kind of one-sided slotted sleeve, comprise sleeve body 1, one end of sleeve body 1 is connected with nut or nut, and sleeve body 1 has elongated slot 2, and elongated slot 2 forms opening and draws to facilitate the wire harness be connected with nut or nut in sleeve body 1 one end.Sleeve body 1 other end is spanner link 3.Spanner link 3 is provided with driving end and connects spacing hole 4, and when key adaptor inserts from sleeve upper ejector lever link 3, key adaptor upper limit ball snaps in described driving end and connects in spacing hole 4.
It is as follows that this one-sided slotted sleeve is used for lambda sensor dismantlement work principle: one-sided slotted sleeve is socketed in the flange face end that lambda sensor carries, lambda sensor wire harness is passed in elongated slot 2, box spanner turns clockwise and drives lambda sensor and oxygen sensing wire harness synchronous rotary, when screw thread pair reaches moment between lambda sensor and ternary catalyzing unit, take off box spanner.
The one-sided slotted sleeve of the present invention adopts milling cutter to slot in standard cartridges when making, carry out grinding process on use sand paper cross-notching surface and crest line, to prevent groove edge, scuffing is caused to wire harness and employee, whole manufacturing process is simple, and manufacture craft is few, and cost of manufacture is low.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious realization of the present invention is not subject to the restrictions described above; as long as have employed the various improvement that method of the present invention is conceived and technical scheme is carried out; or design of the present invention and technical scheme directly applied to other occasion, all in protection scope of the present invention without to improve.
Claims (3)
1. an one-sided slotted sleeve, comprise sleeve body (1), one end of sleeve body (1) is connected with nut or nut, it is characterized in that: in sleeve body (1), have elongated slot (2), described elongated slot (2) forms opening and draws to facilitate the wire harness be connected with nut or nut in described sleeve body (1) one end; Described sleeve body (1) other end is spanner link (3); Described spanner link (3) is provided with driving end and connects spacing hole (4), and when key adaptor inserts from sleeve upper ejector lever link (3), key adaptor upper limit ball snaps in described sleeve upper ejector lever head and connects in spacing hole (4); Described elongated slot (2) opening part has lead angle (5) and is convenient to wire harness importing, described one-sided slotted sleeve is socketed in the flange face end that lambda sensor carries, lambda sensor wire harness is passed in described elongated slot (2), box spanner turns clockwise and drives lambda sensor and oxygen sensing wire harness synchronous rotary, when screw thread pair reaches moment between lambda sensor and ternary catalyzing unit, take off box spanner.
