As a further description of the above technical solution:

and the first upper shell half body and the second upper shell half body are provided with heat dissipation ports at intervals.

As a further description of the above technical solution:

the internal threads of the first upper shell half body and the second upper shell half body are matched to form an internal thread hole.

As a further description of the above technical solution:

the diameter and the length of the oil passing channel are in a contraction arrangement with the upper part wide and the lower part narrow.

As a further description of the above technical solution:

the oil spout is the rectangle mouth.

Compared with the prior art, the utility model provides a casing for differential lock possesses following beneficial effect:

1. in the utility model, the structure of the upper shell of the assembling shell of the differential lock is improved, the whole assembly is improved into half assembly, and the assembly and the half assembly are fixed in an assembling and involuting way;

2. the utility model discloses in, carry out institutional advancement once more to the epitheca of split, set up oily passageway, nozzle, set up the internal thread, realize adding emollient to the differential lock in the outside of casing, spray the mode of interpolation, it is fast, add comprehensively.

Illustration of the drawings:

1. a first upper case half body; 2. a second upper case half body; 3. a rim plate; 4. a threaded hole; 5. an oil passing channel; 6. an oil injection port; 7. an internal thread; 8. a half flange plate.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example (b):

please refer to fig. 1-3, the utility model provides a casing for differential lock, including first epitheca halfbody 1 and second epitheca halfbody 2, first epitheca halfbody 1 and second epitheca halfbody 2 symmetry set up, butt joint department an organic whole of first epitheca halfbody 1 and second epitheca halfbody 2 is along board 3, set up screw hole 4 along the interval on board 3, lie in the inboard of screw hole 4 along board 3 and set up oil passageway 5, the outside of first epitheca halfbody 1 and second epitheca halfbody 2 is communicate in the upper end of oil passageway 5, run through along the inner wall of board 3 and set up the nozzle 6 of intercommunication oil passageway 5, the upper end of passing oil passageway 5 is equipped with internal thread 7, the lower edge an organic whole of first epitheca halfbody 1 and second epitheca halfbody 2 connects half ring flange 8.

Specifically, as shown in fig. 1 and 2, the first upper half casing 1 and the second upper half casing 2 are provided with heat dissipation ports at intervals, so as to facilitate heat dissipation.

Specifically, as shown in fig. 2, the internal threads 7 of the first upper shell half body 1 and the second upper shell half body 2 are matched to form an internal thread hole, which facilitates installation of the bolt.
