In the figure: 1. the square tenon type screw comprises a cylinder body, 2, a concave part, 3, a screw rod, 4, a square tenon connecting block, 5, a screw hole, 6, a mounting hole, 7, a nut, 8, a filling block, 9 and a rotating hole.
Detailed Description
The technical scheme of the invention is further specifically described by the following embodiments and the accompanying drawings.
The utility model provides a filter convenient to fastening, includes barrel 1 that has filter element, the department is sunken downwards in the middle of the barrel 1 roof has hexagon depressed part 2, wherein 2 diapire middle departments of depressed part are vertical to be provided with screw rod 3 to 3 tops of screw rod are not higher than barrel 1 top horizontal plane, prevent that screw rod 3 protrusion from 2 and hanging other objects in depressed part and damaging or damaged.
Wherein the concave part 2 is also provided with a square tenon connecting block 4 matched with the concave part, the top end of the square tenon connecting block 4 extends to the outer side of the cylinder body 1, and a screw hole 5 corresponding to the screw rod 3 is arranged in the middle of the top of the square tenon connecting block 4, and a mounting hole 6 for the screw rod 3 to pass through is arranged on the square tenon connecting block 4 in the middle of the bottom of the screw hole 5, as shown in figure 1, the top end of the screw rod 3 extends into the screw hole 5, wherein the screw hole 5 is internally provided with a nut 7 which is in threaded connection with the screw rod 3, and the diameter of the nut 7 is smaller than the inner diameter of the screw hole 5, when the square tenon connecting block 4 is installed, the bottom end of the square tenon connecting block is inserted into the concave part 2, wherein the screw 5 passes through the mounting hole 6 and extends into the threaded hole 5, which is then locked on the screw 3 by mounting the nut 7 in the threaded hole 5 by means of a socket wrench, this prevents the problem of the lower spring connector block 4 slipping out of the recess 2 without human intervention.
Because the diameter of screw 5 is greater than the diameter of nut 7 and box spanner for box spanner can be smooth take nut 7 spiro union on the screw rod 3 in screw 5, and when needs rotate barrel 1, cover the spanner on the less hexagonal square tenon connecting block 4 of diameter can very conveniently take barrel 1 to realize rotatory purpose through its lateral wall with the contact of depressed part 2, the hexagonal depressed part 2 can block the lateral wall that the square tenon connecting block 4 corresponds at this in-process and prevent that it from rotating in depressed part 2 and can not take barrel 1 to rotate.
A depressed part 2 for fixing 4 bottoms of square tenon connecting block in this embodiment is formed by the barrel 1 roof undercut, make need not to set up the recess on barrel 1 roof like in the past and be used for fixing 4 bottoms of square tenon connecting block, this just makes it be difficult for damaging 1 bulk strength of barrel and when reducing 1 roof thickness of barrel, can also realize playing the purpose of fixed action to 4 bottoms of square tenon connecting block, and in the aforesaid, a screw rod 3 for fixing square tenon connecting block 4 need not to run through 1 roof of barrel, this also makes when it can not only cause the influence to 1 roof intensity of barrel and sealing performance, can also realize fixing the purpose in depressed part 2 with square tenon connecting block 4.
Meanwhile, a filling block 8 is screwed in the screw hole 5 above the nut 7 and the screw rod 3, the top end of the filling block 8 is not higher than the horizontal plane of the top end of the square tenon connecting block 4, and a hexagonal rotating hole 9 is formed in the middle of the top end of the filling block 8. After the square tenon connecting block 4 is installed, the filling block 8 is sealed in the screw hole 5 in a threaded manner, foreign matters are prevented from entering the screw hole 5 and contacting with the nut 7 and the screw rod 3 to damage the screw hole and the screw rod, and the hexagonal rotary hole 9 is convenient for people to stretch the hexagonal wrench to rotate the filling block 8 to enable the filling block to be in threaded connection with the screw hole 5 or rotate out, so that the problem that the filling block 8 cannot rotate is solved.
When the square tenon type oil filter is used, a socket wrench or an opening wrench is sleeved on the square tenon connecting block 4 in the end part of the oil filter, the torque wrench is rotated to screw the oil filter until the sealing gasket contacts the filter base, and 3/4 circles are screwed for 1 circle, so that the oil filter is fastened. The invention does not need to be screwed on the cylinder body 1, has low tool requirement, can be completed by adopting a spanner, and has simple and convenient operation.
The present invention has been described in detail, but the above description is only a preferred embodiment of the present invention, and is not to be construed as limiting the scope of the present invention. All equivalent changes and modifications made within the scope of the present invention shall fall within the scope of the present invention.
