Embodiment Construction
[0021] Below in conjunction with accompanying drawing (mainly with the utilization of single-hole square pad 4 and double-hole rectangular pad 5) briefly illustrate technical scheme of the present invention:
[0022] The present invention is firmly connected and anti-moving. The gasket for the long hole adopts the form of a single-hole square gasket 4, and the single-hole square gasket 4 is a square gasket, and the upper hole position (bolt hole) is opened in the middle, as shown in Figure 1 (a) and Figure 1. 1(b): The adjustable part 2 and the fixed part 3 are connected by bolt 1, the adjustable part 2 is placed on the fixed part 3, and the screw hole on the fixed part 3 is at the length of the adjustable part 2. Within the scope of the shaped hole, the single-hole square washer 4 is placed in the long hole of the adjustable part 2, the screw hole of the single-hole square washer 4 corresponds to the screw hole on the fixed part 3, and the bolt 1 passes through the single-hole...

The invention discloses a firm anti-shifting washer for a slotted hole for a bolt connecting machine element. The washer comprises a gasket arranged between a bolt screw and the slotted hole part of an adjustable machine element, wherein the gasket is a mono-hole square gasket, or a dual-hole rectangular gasket or a multi-hole rectangular gasket, wherein all holes on the multi-hole rectangular gasket are in the same straight line; the mono-hole square gasket is a quadrate gasket, and the hole on the quadrate gasket is positioned in the center; two holes on the dual-hole rectangular gasket are arranged at two sides, and the position of each hole on the dual-hole rectangular gasket which is suitable for two slotted holes in the same straight line respectively corresponds to the bolt position in each slotted hole; and the distance between tow holes on the dual-hole rectangular gasket which is suitable for two parallel slotted hole corresponds to the distance between the two slotted holes. By using the washer provided by the invention, the connection intensity of the machine element can be improved greatly.
Description
(1) Technical field: [0001] The invention relates to a washer for fastening bolts, in particular to a washer for firmly connecting and preventing movement of long holes. (two) background technology: [0002] In all mechanical equipment, threaded connections are used for detachable connections between two parts (parts). This connection method is simple and reliable, and easy to disassemble and assemble. Sometimes, the positions of the two connecting parts need to be changed within a certain range, so a long hole must be made on one of the parts. At this time, if a general-purpose circular washer is used, due to its small contact area with the long hole, the fixation is not firm, and the two parts often move undesirably along the direction of the long hole during work, which affects the normal operation of the equipment. (3) Contents of the invention: [0003] The object of the present invention is to provide a gasket for a long hole with firm connection and anti-movement ...
