Description

Hubs with plastic washers

technical field

The utility model relates to a hinge device, in particular to a hinge device with a plastic washer which can reliably reduce wear, does not produce abnormal sound, and does not need to be lubricated by oiling.

Background technique

The hinge device is widely used in various device structures around people's daily life. The commonly used hinge device usually has a body and a pivot piece. The body and the pivot piece form opposite perforations to A pivot rod is passed through and fixed to achieve pivot connection.

Between the body and the pivot joint of the pivoting member, a washer is generally provided, and the washer is passed through the pivot rod, and is generally made of metal material (such as iron, copper, aluminum, etc.), and its two surfaces are respectively Contacting the surfaces of the pivot joints of the main body and the pivoting member further separates the pivot joints of the main body and the pivoting member, preventing the surfaces of the two pivotal joints from directly wearing each other, resulting in damage after long-term use.

Even so, the method of setting metal washers in the prior art hinges still has some disadvantages in use, such as: the generation of wear cannot be avoided, oiling is often required to keep lubrication, and often occurs during the pivoting process. Unusual sound, the gasket is likely to be unable to fit tightly with the body and pivoting parts due to deformation or surface flatness, and the gasket cannot provide the lateral force for the body and pivoting parts to assist in positioning, etc.

In addition, the pivoting method of the prior art hinge is achieved through the pivot rod, which not only makes the manufacturing of the prior art hinge more complicated, and the cost is not easy to reduce, but also if the pivot rod is accidentally lost, it will become unusable. This is also the shortcoming of this prior art hinge that needs to be improved.

Utility model content

The purpose of this utility model is to provide a hinge device with a plastic gasket, which can effectively improve various shortcomings in the use of the prior art hinge device.

In order to achieve the above-mentioned purpose, the hinge device with plastic gasket of the utility model includes a body and a pivot piece, wherein the body and the pivot piece form opposite perforations at opposite positions, and a pivot rod passes through the pivot piece. fixed in the relative through hole, so that the body and the pivoting member can pivot relative to each other, and it is characterized in that:

At least one plastic washer is pierced on the aforementioned pivot rod, and the plastic washer is located between the body and the pivoting part of the pivot member. It is made of plastic material (for example: plastic or plastic steel, etc.), and it is in the form of a circle In addition, a plurality of grooves are formed at intervals on the two side surfaces, so that the cross-section presents a zigzag shape, and the two side surfaces are respectively attached to the pivotal surfaces of the body and the pivoting member.

Through the arrangement of the plastic washer, when the body and the pivoting member are relatively pivoted, the two sides of the plastic washer can use the design of the groove to reduce the contact area and friction with the body and the pivoting member, respectively. Roughly sliding on the two surfaces of the plastic washer, and through the wear of the plastic washer itself, the wear on the surface of the pivot joint between the body and the pivoting member is surely reduced, not only will there be no abnormal sound, and no oiling is required for lubrication.

In addition, the plastic washer is threaded on the pivot rod, and when its two sides abut against the pivoting surface of the main body and the pivoting member, it can evenly and closely fit the main body and the pivoting part by virtue of its roughly elastic deformation. The surface of the pivoting part of the pivoting part is also braced outward to provide additional lateral force for positioning of the main body and the pivoting part.

In addition, the above-mentioned pivoting member and the body can also be integrally formed with a shaft protrusion and penetrate to form a perforation corresponding to the shaft protrusion. In this way, the hinge device with plastic gasket of the present invention can pass through the shaft. The protrusion is snapped into the through hole to achieve pivoting. The manufacturing process is relatively simple and fast, with fewer components and the cost can be greatly reduced, and it can completely avoid the problem of being unable to use due to the loss of the pivot, thus effectively improving the prior art. Shortcomings.

Detailed ways

Please refer to Fig. 1 and Fig. 2, the hinge device with plastic washers of the present invention includes a body 10, a pivot member 20, two pivot sets 30 and a plurality of plastic washers 40, wherein:

The main body 10 is a ㄇ-shaped sheet body, and a fixing hole 11 is formed through the middle section, and the fixing hole 11 can pass through a fixing member (not shown) to be locked on a fixed plane (such as a computer screen) The top surface of the base); its two free ends are relatively vertically protruding and formed with two limiting pieces 12, and adjacent to the two free ends are penetrated and formed with first perforations 13;

The pivoting member 20 has a fixed plate, and one side of the fixed plate can be installed for a general device structure (for example: a display panel of a computer screen) to pivot relative to the fixed plane (the base); Two pivot parts 21 are vertically connected, and the pivot parts 21 are respectively formed with non-circular second through holes 210 oppositely at the adjacent ends, and a limiting groove 211 with a specific length is formed on one edge respectively; wherein, The second through holes 210 correspond to the first through holes 13 of the main body 10; The relative pivot angle of the body 10;

The two pivot groups 30 respectively have a pivot 31 and a fixing piece 32, the cross section of the pivot 31 is non-circular with respect to the second through hole 210, and pass through the corresponding first through hole 13 and the second through hole 210 respectively. in the center, and respectively have an end 310 against the surface of the pivot 21; the center of the fixing piece 32 is formed with a non-circular joint hole 320 relative to the pivot 31, for the fixing piece 32 to be sleeved on the end of the pivot 31 respectively , fixed on the pivot rod 31 by riveting, so that the pivot member 20 and the body 10 are combined with each other and can pivot relative to each other;

Please refer to Fig. 3 and Fig. 4, the plastic washer 40 is installed on the pivot 31, and is respectively located between the fixed piece 32 and the free end of the body 10, and between the free end of the body 10 and the pivot 21. It is made of plastic material (for example: plastic or plastic steel, etc.), it is in the form of a circle, and a plurality of grooves 41 are formed at intervals on the two sides of the surface, so that the cross-section is in a zigzag shape, and the two sides of the surface are respectively attached to the fixed The piece 32 , the free end of the main body 10 and the pivotal surface of the pivotal portion 21 .

Through the arrangement of the plastic washer 40, when the body 10 and the pivoting member 20 pivot relatively, the two sides of the plastic washer 40 can reduce the contact with the body 10 and the pivoting member 20 by virtue of the design of the groove 41 Area and friction force, so that the body 10 and the pivoting member 20 roughly slide on the two surfaces of the plastic washer 40 respectively, and the wear of the plastic washer 40 itself can reduce the wear of the surface of the pivot joint. In addition Not only will there be no abnormal sound, but also there is no need for oiling for lubrication.

In addition, please refer to FIG. 5. In another preferred embodiment, the pivots 21 of the aforementioned pivoting member 20 are respectively processed by deep drawing, and a non-circular cross-section is protrudingly formed integrally. The shaft protrusion 212 is used to replace the aforementioned pivot rod 31; and the first through holes 13 on the two free ends of the body 10 are respectively opposite to the shaft protrusion 212 and are engaged with the shaft protrusion 212 to achieve pivoting; in this way, the utility model The manufacturing process of the hinge device with plastic gasket is relatively simple and fast, the cost can be greatly reduced due to fewer components, and the problem that the hinge rod 31 is lost and cannot be used can be completely avoided.
