Abstract
The utility model relates to the technical field of sealing devices, especially relates to an easy removable oil seal, which comprises an oil seal body, wherein a rising portion is fixed on an upper end on one side of the oil body; an upper elevation angle is formed between the rising portion and an upper surface of the oil body; a clamping installation elastic projection having an interference fit with a recess on a transmission component is fixed on a lower end of the oil seal body opposite to one side of the rising portion; and two sides on a lower portion of the clamping installation elastic projection are arc-shaped portions. According to the utility model, the recess is opened on the transmission component, and when being installed, the clamping installation elastic projection having interference fit with the recess on the oil seal body is directly pushed into the recess and the fixture is realized; when being removed, the rising portion is pushed down and the clamping installation elastic projection will be popped out from the recess; and in this way, the oil seal can be easily removed.
Description
Technical field
The utility model relates to seal arrangement technical field, particularly a kind of easy-to-dismount oil sealing.
Background technique
Oil sealing is the mechanical component for oil sealing (oil is modal liquid substance in transmission system, also makes a general reference the meaning of general liquid substance), it will in transmission part, need lubricated parts and the parts isolation of exerting oneself, be unlikely to allow oil seepage.
Chinese invention patent CN 102758917 A disclose a kind of oil sealing, comprise oil sealing main body, rubber spring and back-up ring, and oil sealing main body two ends are provided with rubber spring, and rubber spring is fixedly connected with back-up ring, is provided with circular groove on back-up ring.This oil seal structure is simple, easy to use, practical, has strengthened the sealability at running shaft place, surface friction drag is little, wear-resistant, has reduced the replacing efficiency of oil sealing, has saved material, extend the working life of oil sealing, improved manufacturing efficiency, be easy to apply.
Summary of the invention
The utility model technical issues that need to address are to provide a kind of easy-to-dismount oil sealing.
For solving above-mentioned technical problem, a kind of easy-to-dismount oil sealing of the utility model comprises oil sealing body, and described oil sealing body one side upper end is fixed with warping part, and described warping part becomes vertical angle with oil sealing body upper surface; A side seal body lower end relative to described warping part is fixed with the elastic bumps that clamps with transmission part upper groove interference fit, described in to clamp both sides, elastic bumps bottom be curved portions.
Further, edge, described oil sealing body lower end is arc tips.
Further, described warping part upper surface is provided with and increases the parts that rub.
Further, the described increasing parts that rub are semicircle cylindricality fin.
Further, the capable fin of described semicolumn is four, becomes arranged in step shape along the nose-up direction of warping part.
Adopt after said structure, the utility model by offering groove on transmission part, when installation directly by with the oil sealing body of groove interference fit on the elastic bumps that clamps be pressed in groove and can fix, when dismounting, press warping part, clamping like this elastic bumps will eject in groove, so just can easily oil seal demounting be got off.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is worm's eye view of the present utility model.
Fig. 2 is plan view of the present utility model.
Fig. 3 is left view of the present utility model.
In figure: 1 is oil sealing body, 2 is arc tips, and 3 is warping part, and 4 is fin, and 5 for clamping elastic bumps, and 6 is curved portions.
Embodiment
As shown in Figure 1, Figure 2 and Figure 3, a kind of easy-to-dismount oil sealing of the utility model comprises oil sealing body 1, and described oil sealing body 1 one side upper ends are fixed with warping part 3, and described warping part becomes vertical angle with oil sealing body upper surface.Be fixed with in side seal body 1 lower end relative to described warping part with transmission part upper groove interference fit clamp elastic bumps 5, described in to clamp elastic bumps 5 both sides, bottom be curved portions 6.Because warping part 3 is relatively-stationary with clamping elastic bumps 5, so in the time pressing warping part 3, the oil sealing body that clamps elastic bumps 5 one end will upwarp.
Further, in order to be more convenient to dismantle oil sealing, described oil sealing body 1 edge, lower end is arc tips 2, like this in the process of dismounting oil sealing, and the phenomenon that oil sealing body just can not engage with transmission part.
Further, described warping part 3 upper surfaces are provided with and increase the parts that rub, and increasing the parts that rub described in present embodiment is semicircle cylindricality fin 4.Be four with the capable fin of semicolumn described in Fig. 3 as shown in Figure 1, Figure 2, become arranged in step shape along the nose-up direction of warping part.
Working principle of the present utility model is as follows: when installation directly by with the oil sealing body of groove interference fit on the elastic bumps 5 that clamps be pressed in groove and can fix; As shown in Figure 3, press warping part when dismounting, the curved portions 6 that clamps like this elastic bumps 5 both sides, bottom will eject in groove, so just can easily oil seal demounting be got off.
Certainly, the utility model also can adopt increases friction plate or other the applicable increasings parts that rub, within such conversion all drops on protection domain of the present utility model.
Claims (5)
