Compared with prior art, flange provided by the utility model,, reduced the loss of weight through hole weight of flange by being set, the quantity that the loss of weight through hole is set simultaneously is four, and be uniformly distributed in the flange main part, the mechanical strength that has guaranteed the flange each several part is consistent, and guarantees the firm and working life of flange integral body.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing relevant of the present utility model in the following describes only is embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the plan view of flange among the utility model one embodiment.
Wherein, reference character is:
Flange, 100; Main part, 10; Through hole is installed, 11; The first through hole, 121; The second through hole, 122; Third through-hole, 123; Fourth hole, 124.
Embodiment
Below with reference to each embodiment shown in the drawings the utility model is described in detail.But these embodiments do not limit the utility model, and the conversion on the structure that those of ordinary skill in the art makes according to these embodiments, method or the function all is included in the protection domain of the present utility model.
Join shown in Figure 1, the utility model provides a kind of flange 100, it comprises main part 10, described main part 10 comprises the installation through hole 11 that penetrates described main part 10 and is positioned at the loss of weight through hole of described installation through hole 11 peripheries, the cross section of described installation through hole 11 is circular, and described loss of weight through hole cross section is the semicircle district that comprises squared region and be arranged at the squared region both sides.
Described loss of weight through hole can effectively reduce the weight of flange 100, and then reduces the weight of the machinery of using this flange 100, reduces the cost of transportation of this machinery.
Wherein, described loss of weight number of openings arranges 4.
Concrete, the quantity of described installation through hole 11 is set to 1.
Especially, described loss of weight through hole comprises the first loss of weight through hole 121 and the second loss of weight through hole 122, and described the first loss of weight through hole 121 is the center of circle of the cross section of described installation through hole 11 with the centre of described the second loss of weight through hole 122.
