Description

A kind of shell structure of included screw

Technical field

The utility model relates to components installing areas, in particular to a kind of shell structure of included screw.

Background technique

The shell structure of included screw is very widely used, such as in field of electronic device, using the shell of included screw Structure is very convenient to the maintenance of equipment, currently, the shell of included screw mostly uses gasket that included screw is limited on shell, To prevent screw from falling off.

However, assist materials and parts as gasket, if will cause at high cost using metal gasket, and special work is needed Tool could assemble screw, gasket and shell；If using material for the gasket of wheat membrane, since the material is soft for it, gasket pole It easily is easy to fall loss, so that shell is lost the function of included screw, can make troubles instead to maintenance.

For the above problem in the presence of the prior art, a kind of shell structure of new included screw is provided with important Meaning.

Utility model content

To solve the above problems, the utility model provides a kind of shell structure of included screw, do not need by auxiliary Materials and parts realize included function, and processing is very convenient.

To achieve the above object, the shell structure of the included screw of the utility model, including first shell and second shell, By the fastened by screw, being respectively equipped in the first shell and second shell can be with for the first shell and second shell The first threaded hole and the second threaded hole of the screw cooperation, the threaded portion of the screw are set to the head of the screw, institute The head for stating screw passes through first threaded hole and is threadedly coupled with second threaded hole.

Preferably, cavity is formed between the first shell and second shell, the head of the screw sequentially passes through institute The first threaded hole and the cavity is stated to be threadedly coupled with second threaded hole.

Further, height of the height of the cavity not less than the threaded portion of the screw.

Further, the first shell and/or the second shell are equipped with the groove for being used to form the cavity.

Preferably, the first shell is metal shell.

The shell structure of the included screw of the utility model, by the way that the first threaded hole is arranged on the first shell, it can be achieved that After first shell and second shell separation, the threaded portion of screw is stopped by the internal screw thread of the first threaded hole, to realize screw It will not fall off from first shell, this structure does not need that the function that shell carries screw can be realized by other auxiliary materials and parts Can, it is not in the phenomenon that included function is lost, and processing is also very convenient.

Specific embodiment

In the following, structure and working principle to the utility model etc. are further described in conjunction with attached drawing.

Referring to figs. 1 to 4, the shell structure of the included screw of the utility model, including first shell 10 and second shell 30, first shell 10 and second shell 30 are fastened by screw 20, and being respectively equipped in first shell 10 and second shell 30 can The first threaded hole 11 and the second threaded hole 31 cooperated with screw 20, the threaded portion 21 of screw 20 are set to the head of screw 20, The head of screw 20 passes through the first threaded hole 11 and is threadedly coupled with the second threaded hole 31.When screw 20 is revolved from the second threaded hole 31 Out, when first shell 10 and second shell 30 separate, the threaded portion 21 of screw 20 is limited in the lower section of the first threaded hole 11, prevents Only screw 20 falls off from first shell 10.

Specifically, as shown in figure 3, when screw 20 is just screwed out from the second threaded hole 31, the threaded portion 21 of screw 20 Positioned at the lower section of the internal screw thread of the first threaded hole 11, the internal screw thread of the first threaded hole 11 can stop screw 20 de- from first shell 10 Out.

In order to realize that the threaded portion 21 of screw 20 is limited in the lower section of the first threaded hole 11, first shell 10 and second shell Cavity 4 is formed between body 30, one end of the cavity 4 is connected to the first threaded hole 11, and the other end is connected to the second threaded hole 31, The head of screw 20 sequentially passes through the first threaded hole 11 and cavity 4 and is threadedly coupled with the second threaded hole 31.

In order to realize the internal screw thread of the first threaded hole 11 to the barrier effect of the threaded portion 21 of screw 20, the cavity 4 Height of the height not less than the threaded portion 21 of screw 20.As shown in figure 3, the height of cavity 4 is equal to the threaded portion of screw 20 21 height.

There are many formation forms of above-mentioned cavity 4, for example, can set in the lower section that first shell 10 is located at the first threaded hole 11 The first groove is set, which connects to forming cavity 4 with the top of second shell 30；Also it can be located at second in second shell 30 The second groove 32, the bottom connection formation cavity 4 of second groove 32 and first shell 10 is arranged in the top of threaded hole 31.When So, a groove can also be opened up in first shell 10 and second shell 30, two grooves, which are connected, can form cavity 4。

In order to further ensure that the internal screw thread of the first threaded hole 11 can stop the threaded portion 21 of screw 20 to move up, first The material of shell 10 is preferably on-deformable metal material.

The shell structure of the included screw of the utility model can by the way that the first threaded hole 11 is arranged in first shell 10 After realizing that first shell 10 and second shell 30 separate, the threaded portion 21 of screw 20 is hindered by the internal screw thread of the first threaded hole 11 Gear, to realize that screw 20 will not fall off from first shell 10, this structure is not needed can be real by other auxiliary materials and parts Existing shell carries the function of screw, is not in the phenomenon that included function is lost, and processing is also very convenient.

More than, the only schematic description of the utility model, it will be recognized by those skilled in the art that practical without departing from this On the basis of novel working principle, a variety of improvement can be made to the utility model, this belongs to the protection of the utility model Range.
