Description

Technical Field

[0001] The utility model relates to the technical field of gaskets, in particular to a combined adjustable steel gasket. Background Art

[0002] Washers are thin circular plates with a through hole in the center, used to distribute the load of threaded fasteners. Other uses include as spacers, springs, wear pads, pre-display devices, locking devices, etc. Washers can be divided into non-metallic washers, metal washers, and metal-non-metallic combination washers according to their materials and structural characteristics. Each category can be subdivided into several types. Among them, stainless steel washers are made of stainless steel, with high strength and good durability, and are widely used in various fields.

[0003] However, the thickness of the steel gasket at this stage is fixed. When there is a thickness deficiency in actual application, two or more gaskets are usually stacked. However, the multiple gaskets are not a whole. When the position of the applied gasket needs to be rotated, there must be sliding friction between the multiple gaskets, and they are in rigid contact with each other, which greatly reduces the service life of the gasket. Therefore, a combined adjustable steel gasket is proposed. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0021] The following describes an embodiment of the utility model based on its overall structure.

[0022] A combined adjustable steel spacer, such as Figure 1-5 As shown, it includes a steel gasket 100, which is composed of an upper gasket frame 110 and a lower gasket frame 120. The upper gasket frame 110 is arranged directly below the lower gasket frame 120. The lower gasket frame 120 is embedded with an inner frame 130 extending to the interior of the upper gasket frame 110, and the upper gasket frame 110 and the lower gasket frame 120 are slidably connected through the inner frame 130. The top of the inner frame 130 is located on the inner side of the lower gasket frame 120 and is fixedly connected with a rubber ring tube 150. An elliptical ring tube 151 is fixed inside the rubber ring tube 150. A lower inner ring 140 is fixed to the inner bottom of the upper gasket frame 110. A plurality of stepped grooves 141 are provided on the top of the lower inner ring 140. An upper inner ring 160 is fixedly connected to the inner top of the inner frame 130. A plurality of docking blocks 161 are fixed to the bottom of the upper inner ring 160.

[0023] A blind hole 142 is formed at the top of the stepped groove 141 , and an insertion rod 162 plugged into the blind hole 142 is fixed at the bottom of each set of docking blocks 161 .

[0024] The top of the upper cushion frame 110 is provided with a plurality of notches in a circular array near the outer wall, and the bottom of the lower cushion frame 120 is provided with a plurality of notches near the outer wall at positions corresponding to the notches.

[0025] The top of the lower inner ring 140 is located at the bottom ring opening of the inner frame 130 .

[0026] When the thickness of the steel gasket 100 needs to be adjusted, the lower gasket frame 120 can be slightly pulled upward to make the insertion rod 162 away from the inside of the blind hole 142, and then rotated to drive the inner frame 130 to rotate. When the inner frame 130 rotates, the upper inner ring 160 can be rotated. When the upper inner ring 160 rotates, the docking block 161 and the insertion rod 162 can be driven to move. The insertion rod 162 can move along the surface of the stepped groove 141. Due to the special shape of the stepped groove 141, the lower gasket frame 120 and the inner frame 130 can cooperate with each other to change their thickness. When the steel gasket 100 is adjusted to the required thickness, the top of the upper gasket frame 110 and the lower gasket can be observed. Whether the notch and the notch at the bottom of the frame 120 correspond to each other, when the notch and the notch correspond to each other, it means that the insertion rod 162 has been moved to a position where it can be plugged into the blind hole 142. At this time, pressing down the cushion frame 120 can make the insertion rod 162 completely plugged into the interior of the blind hole 142. In order to prevent the steel gasket 100 from being in rigid contact due to external pressure and affecting its service life during use, a rubber ring tube 150 is arranged on the top of the inner frame 130. When subjected to external pressure, the lower cushion frame 120 is depressed downward and squeezed onto the surface of the rubber ring tube 150 to cause it to deform. In addition, an elliptical ring tube 151 is arranged inside the rubber ring tube 150 to further improve the support and pressure resistance of the rubber ring tube 150.

[0027] Please refer to Figure 2 The inner side walls of the upper cushion frame 110 and the lower cushion frame 120 are provided with restraining ring grooves, and the inner and outer walls of the inner frame 130 are sleeved with restraining rings near the upper and lower ends.

[0028] The upper pad frame 110 and the lower pad frame 120 can slide easily through the inner frame 130 , which is beneficial to improving the rationality of using the steel gasket 100 .

[0029] Please refer to Figure 2 The curved inner wall and the curved outer wall of the inner frame 130 are both fixed with rubber anti-skid pads.

[0030] The provision of the rubber anti-skid pad can increase the friction between the upper cushion frame 110 , the lower cushion frame 120 and the inner frame 130 , thereby preventing the upper cushion frame 110 and the lower cushion frame 120 from sliding along the outer wall of the inner frame 130 .

[0031] When in use, if the thickness of the steel gasket 100 needs to be adjusted, the lower pad frame 120 can be slightly pulled upwards to make the insertion rod 162 away from the inside of the blind hole 142, and then rotated to drive the inner frame 130 to rotate. When the inner frame 130 rotates, the upper inner ring 160 can be rotated. When the upper inner ring 160 rotates, the docking block 161 and the insertion rod 162 can be driven to move, and the insertion rod 162 can move along the surface of the stepped groove 141. Due to the special shape of the stepped groove 141, the lower pad frame 120 and the inner frame 130 can cooperate with each other to change their use thickness. When the steel gasket 100 is adjusted to the required thickness, it can be observed whether the notch and the groove opened at the top of the upper pad frame 110 and the bottom of the lower pad frame 120 correspond to each other. When the notch corresponds to the slot, it means that the insertion rod 162 has moved to a position where it can be plugged into the blind hole 142. At this time, pressing down the cushion frame 120 can make the insertion rod 162 completely plugged into the interior of the blind hole 142. In order to prevent the steel gasket 100 from being in rigid contact due to external pressure and affecting its service life during use, a rubber ring tube 150 is provided on the top of the inner frame 130. When subjected to external pressure, the lower cushion frame 120 is depressed downward and squeezes the surface of the rubber ring tube 150 to cause it to deform. The elliptical ring tube 151 is provided inside the rubber ring tube 150 to further improve the support and pressure resistance of the rubber ring tube 150, thereby improving the service life of the device. The parts not involved in the device are the same as the prior art or can be implemented using the prior art.

The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples.
