Abstract
The utility model discloses a loose proof binding device for oil holes, comprising a casing body, a bolt and a seal cushion. The casing body is provided with a fixing hole and a through hole which is connected with the fixing hole. The bolt is fixed in the fixing hole by the seal cushion. The diameter of the through hole is smaller than that of a spring. The spring is provided in the fixing hole which is equipped between the bolt and the through hole. One end of the spring id contacted with the bolt, and the other end is contacted with the end surface of the fixing hole. The spring can not be loose by the elastic effect of the spring. The utility model has the advantages of simple structure, convenient installment and usage, low cost, good sealing performance and the like.
Description
The utility model relates to a kind of locking securing means, the locking oilhole securing means that particularly a kind of oilhole is used.
Present existing product and equipment generally are provided with lubrication system, and lubrication system generally all is provided with tank filler sleeve and oil drainage hole, and most of oilholes all adopt bolt to add sealing of seal washer method; Though adopt this method to have easy to process, simple in structure, low cost and other advantages; But product and equipment cause bolt looseness easily in running, and the phenomenon that produces leakage of oil or oil impregnate but can not find good solution all the time, makes equipment surface be easy to generate greasy dirt, influence attractive in appearance, increase fuel consumption.
For overcoming the problem of above-mentioned existence, the purpose of this utility model just provides a kind of locking oilhole securing means of simple in structure, easy to install, loosening, good seal performance.
For achieving the above object, a kind of locking oilhole securing means of the present utility model, comprise casing, bolt and seal washer, the through hole that casing is provided with fixed hole and links to each other with fixed hole, bolt is fixed on the fixed hole by seal washer, and described through-hole diameter is provided with spring less than spring diameter on the fixed hole between bolt and the through hole, spring one end contacts with bolt, and the other end contacts with the end face of fixed hole.
For the ease of observing the oil level height, need be fixed with the dipstick bar on the described bolt, the dipstick bar stretches in the casing by through hole.Described dipstick bar is provided with the scale sign.
The utility model since at through-hole diameter less than spring diameter, on the fixed hole between bolt and the through hole, be provided with spring, it is loosening that the elastic force effect by spring can not produce bolt; Have simple in structure, easy to install, advantages such as cost is low, good seal performance.
Below in conjunction with the drawings and the specific embodiments the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Shown in Figure 1, a kind of locking oilhole securing means of the present utility model, comprise casing 3, bolt 1 and seal washer 2, the through hole 5 that casing 3 is provided with fixed hole 8 and links to each other with fixed hole 8, bolt 1 is fixed on the fixed hole 8 by seal washer 2, and through hole 5 diameters are less than spring 4 diameters, on the fixed hole 8 between bolt 1 and the through hole 5, be provided with spring 4, bolt 1, spring 4 and through hole 5 are arranged on the same axis, and spring 4 one ends contact with bolt 1, and the other end contacts with the end face of fixed hole 8.Can be easily on the tank filler sleeve of product and equipment or oil drainage hole, use, under the elastic force effect of spring 4, well solved the phenomenon of leakage of oil or oil impregnate.
When the utility model uses at tank filler sleeve, observe the oil level height in the fuel tank for convenience, on bolt 1, be fixed with dipstick bar 6, dipstick bar 6 stretches in the casing 3 by through hole 5.Dipstick bar 6 is provided with scale sign 7.
