Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model is not subject to the restriction of embodiment.
Unless separately there is other clearly to represent, otherwise in whole specification and claims, term " comprises " or its conversion was stated being understood to include as " comprising " or " including " etc. element or constituent element, and do not get rid of other element or other constituent element.
As shown in Figure 2, according to the black box of the utility model embodiment, it can seal the oil duct of part or watercourse port, the oil duct of part or watercourse port place end face have the screw of tightening, the present embodiment specifically be take the watercourse port of part and is described as example, sealing assembly comprises T-shaped screw rod 1, fixed block 2, flange face bolt 3 and Sealing 5, fixed block 2 is spill, fixed block 2 two ends have the U-shaped nail hole 21 of crossing, T-shaped screw rod 1 is located at the intermediate portion of fixed block 2, flange face bolt 3 can be followed closely hole 21 through U-shaped mistake and mate with the screw that tightens of the watercourse port 61 of part 6, flange face bolt 3 can be fixed on fixed block 2 end face at watercourse port 61 places of part 6, and the watercourse port 61 of the spill mouth alignment element 6 of fixed block 2, Sealing 5 can fasten the watercourse port 61 of part 6 completely, the upper end of Sealing 5 is provided with the socket (unmarked in figure) mating with the screw head of T-shaped screw rod 1, the screw head of T-shaped screw rod can be for square, the screw head interference fit of socket and T-shaped screw rod 1.In addition, on T-shaped screw rod 1, can be provided with stop nut 4, when sealing, move T-shaped screw rod 1 while upwards exiting, play position-limiting action, the while can prevent that sealing block 5 from coming off.
In such scheme, fixed block 2 works the effect of twisting of carrying T-shaped screw rod 1, the U-shaped nail hole of crossing is opened for laying flange face bolt 3 in both sides, flange face bolt 3 can be selected hex head bolt, by U-shaped, cross that nail hole is adjustable tightens different pitch L(referring to Fig. 3) and different sizes tighten screw, the centre of fixed block 2 has screw 22 and is used in conjunction with the screw rod of T-shaped screw rod 1, the space that the spill mouth of fixed block 2 provides T-shaped screw rod 1 and remaining part to move up and down.T-shaped screw rod upper end is handle (unmarked in figure), coordinate with fixed block 2 screws, regulate T-shaped screw rod to move up and down, the head of T-shaped screw rod is square, with the square opening interference fit of Sealing 5, play fit sealing part 5 and anti-rotation effect, Sealing 5 is polyurethane material, for obturator, its boundary dimension can be changed adjustment according to part oil duct or watercourse port actual size size.
As shown in Figure 3, while using this black box, first Sealing 5 is aligned to the watercourse port 61 of part 6, tighten hexagon flange bolt 3, fixed block 2 is fixed, clockwise direction is twisted T-shaped screw rod 1, now T-shaped screw rod 1 moves down, to Sealing 5, be adjacent to the watercourse port 61 of part 6, the large I of sealing load regulates arbitrarily, and river sun can carry out the water channel leak test of part.After having sealed, counterclockwise twist T-shaped screw rod 1, on T-shaped screw rod 1, move, unclamp sealing, and put by stop nut 4 restriction superior displacements, now unclamp hexagon flange bolt 3, can remove this black box.
In a word, by screw-thread fit, active force directly seals the oil duct of part or watercourse port, and sealing station is with strong points, reduces sealing area, makes pressure concentration, can adjust arbitrarily sealing load by changing screwing force size, and sealing effect is better.In addition, by open the U-shaped nail hole of crossing on fixed block, can meet the designing requirement of the different screw spacing of part and screw size, highly versatile.
The aforementioned description to concrete exemplary of the present utility model is for the object with illustration is described.These descriptions not want the utility model to be defined as disclosed precise forms, and obviously, according to above-mentioned instruction, can much change and change.Exemplary embodiment is selected and the object described is to explain certain principles of the present utility model and practical application thereof, thereby made those skilled in the art can realize and utilize various exemplary of the present utility model and various selection and change.Scope of the present utility model is intended to be limited by claims and equivalents thereof.
