In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the schematic diagram of the utility model lambda sensor installation site;
Fig. 2 is the structural representation of the utility model lambda sensor;
Fig. 3 is the structural representation of the utility model lambda sensor dismantling spanner.
Detailed description of the invention
For making the object of the utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Fig. 1 is the schematic diagram of the utility model lambda sensor installation site, Fig. 2 is the structural representation of the utility model lambda sensor, Fig. 3 is the structural representation of the utility model lambda sensor dismantling spanner, refer to Fig. 1, Fig. 2, Fig. 3, the present embodiment provides a kind of lambda sensor dismantling spanner, comprising: sleeve 202 and the handle 201 be fixedly connected on described sleeve 202 outer wall; Along its central axis direction on described sleeve 202, offer the groove 204 running through described sleeve two ends, described groove 204 is communicated with the inside and outside wall of described sleeve 202; The width of described groove 204 is greater than the width of lambda sensor wire harness 302; The external diameter of described sleeve 202 is less than the aperture of lambda sensor via hole 106.
Particularly, lambda sensor comprises lambda sensor plug connector 303, lambda sensor wire harness 302 and oxygen sensor probe 301, and oxygen sensor probe 301 is arranged in the lambda sensor via hole 106 of tracheae heat shield 103.
Use procedure is, by the groove 204 of lambda sensor wire harness 302 through lambda sensor dismantling spanner, enter the endoporus of sleeve 202, then lambda sensor dismantling spanner is moved to oxygen sensor probe 301 direction, make sleeve 202 enter in via hole 106, oxygen sensor probe 301 enters the endoporus of sleeve 202, and then by operating grip 201 turnbarrel 202, to drive oxygen sensor probe 301 to rotate, thus oxygen sensor probe 301 is back-outed from via hole 106.
It should be noted that although in the installation process of lambda sensor, to there is not the situation that sleeve 202 cannot enter via hole 106, that is, use common open-end wrench just installation can be completed.But the lambda sensor dismantling spanner that the present embodiment also can be used to provide carries out the installation of lambda sensor, parts are installed compacter.
The lambda sensor dismantling spanner that the present embodiment provides, by offering the groove 204 running through described sleeve two ends on sleeve 202 along its central axis direction, and the width of groove 204 is greater than the width of lambda sensor wire harness 302, the external diameter of sleeve 202 is less than the aperture of lambda sensor via hole 106, can by the groove 204 of lambda sensor wire harness 302 through lambda sensor dismantling spanner during dismounting, enter the endoporus of sleeve 202, then lambda sensor dismantling spanner is moved to oxygen sensor probe 301 direction, sleeve 202 is made to enter in via hole 106, oxygen sensor probe 301 enters the endoporus of sleeve 202, and then by operating grip 201 turnbarrel 202, rotate to drive oxygen sensor probe 301, thus oxygen sensor probe 301 is back-outed from via hole 106.When not removing miscellaneous part, directly can dismantle lambda sensor, the unloading process time is short, and can not cause damage to miscellaneous part.
In the present embodiment, further, handle 201 can be arranged at one end of sleeve 202, so that sleeve 202 is put in via hole 106.
Preferably, handle 201 is vertical relative to sleeve 202, easy to use.
Further, the endoporus of sleeve mates with oxygen sensor probe 301, is convenient to oxygen sensor probe 301 to dismantle.
In practical application, sensor probe 301 can be hexagonal structure, accordingly, the endoporus 205 of sleeve 202 can be hexagon ring, thus mates completely with the hexagonal structure on sensor probe 301, can facilitate the dismounting to lambda sensor further.
Further, the width of groove 204 is less than the internal diameter of sleeve 202, and the width defining groove 204 is no more than the diameter of sleeve 202, and the width avoiding groove is excessive, causes lambda sensor to dismantle.
Preferably, handle 202 also has hand grip portion 203, and the Breadth Maximum of hand grip portion 203 is greater than the Breadth Maximum of handle 202.Wherein, hand grip portion 203 can, for being wrapped in the rubber layer outside handle 202, be convenient to hold and use.
In order to more convenient use, preferably, the width of described groove is 14mm, and the external diameter of described sleeve is 22mm.Above-mentioned size is only preferred size, and the width of groove and the external diameter of sleeve can be also other sizes, are not specifically limited at this.
Last it is noted that above each embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to foregoing embodiments, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein some or all of technical characteristic; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the scope of each embodiment technical scheme of the utility model.
