Description

Technical Field

[0001] The utility model relates to the field of screws, in particular to a press-type screw. Background Art

[0002] Screws are a commonly used connector in the prior art. For example, a commonly used screw on a camera is a screw with a D-shaped ring on the head. When the screw is installed on the camera, the D-shaped ring can be used to connect the strap to facilitate carrying the camera. However, the head of the screw is fixed to the screw rod. After the screw is installed, when the camera is subsequently carried and used, the strap drives the D-shaped ring to rotate back and forth, which can easily cause the screw to loosen, causing the screw to separate from the camera, causing the camera to fall and break. Therefore, improvements are needed. Utility Model Content

[0019] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "inner", "outer", "vertical", "circumferential" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0021] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] In the description of the present utility model, "first feature" and "second feature" may include one or more of the features. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0023] like Figure 1-Figure 5 The push-type screw shown includes: a connecting piece 1, a push shell 2, a screw body, a spring 9 and a retaining spring 10.

[0024] The outer part of the pressing housing 2 is provided with a connecting member 1, such as Figure 1 and Figure 2 As shown, the connecting member 1 here is a D-shaped ring, which is rotatably arranged on the pressing housing 2. When the pressing screw of this solution is installed on the camera, the D-shaped ring can be used to connect the shoulder strap to facilitate the camera to be carried. Of course, the connecting member 1 can also adopt other structural forms, which are not limited here, and those skilled in the art can set it according to their own functional requirements.

[0025] like Figure 4 and Figure 5 As shown, the inner hollow of the housing 2 is pressed to form a mounting cavity 3, the bottom of the mounting cavity 3 is open, the inner top wall of the mounting cavity 3 is provided with a first locking portion 4, and the inner peripheral wall of the mounting cavity 3 is provided with a locking groove 5.

[0026] The screw body includes a screw head 6 and a screw rod 7 connected to the screw head 6. A second engaging portion 8 is provided on the top of the screw head 6. The screw head 6 extends from the bottom of the installation cavity 3 into the installation cavity 3. A spring 9 is provided on the outer sleeve of the screw head 6. The spring 9 abuts against the inner top wall of the installation cavity 3. The retaining spring 10 is clamped in the slot 5 and is located below the screw head 6. The retaining spring 10 is an existing product, also called a retaining ring or a buckle, and is a kind of fastener that prevents the axial movement of parts on the shaft or the hole. The retaining spring 10 in this solution is mainly used to prevent the screw body from falling off from the pressing shell 2.

[0027] In actual use, the push-type screws in this solution have a push-on state and a normal separation state:

[0028] In the pressed engagement state, the pressing shell 2 is pressed by external force to compress the spring 9 so that the first engaging portion 4 is engaged with the second engaging portion 8. At this time, the pressing shell 2 and the screw body can rotate synchronously, so that the screw body can be disassembled or installed.

[0029] like Figure 5 As shown, in the normal separation state, that is, when the pressing housing 2 is not subjected to external force, the spring 9 will push the first engaging portion 4 and the second engaging portion 8 apart, and the two are no longer engaged. At this time, the pressing housing 2 can rotate freely around the axis of the screw body. Therefore, when the pressing screw is installed in the camera, the rotation of the pressing housing 2 will not drive the screw body to rotate, thereby preventing the screw body from loosening and separating from the camera.

[0030] In further settings, such as Figure 2 and Figure 3 As shown, the first engaging portion 4 is a hexagonal protrusion, and the second engaging portion 8 is a hexagonal groove. This structure is simple and easy to implement. Of course, the first engaging portion 4 and the second engaging portion 8 can also be in other forms, as long as the pressing housing 2 and the screw body can rotate synchronously after the two are engaged.

[0031] like Figure 4 and Figure 5 As shown, the outer peripheral edge of the screw head 6 is provided with an annular flange 11, the spring 9 abuts against the flange 11, and the retaining spring 10 is located below the flange 11. The screw rod 7 may be provided with a gasket 12 to improve the anti-slip and sealing effect after the screw is installed.

[0032] It is understandable that, in addition to being installed on cameras, the push screw can also be used in other fields, and those skilled in the art can select it according to actual conditions.

[0033] To sum up, the push-type screw in the present solution has multiple functions. When the pressing shell 2 is engaged with the screw body, the two can rotate synchronously, so that the screw body can be disassembled or installed normally; and when the pressing shell 2 is no longer engaged with the screw body, the rotation of the pressing shell 2 will not drive the screw body to rotate. In this case, the screw body can be prevented from loosening, and it is very flexible and convenient to use.

[0034] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
