Description

Technical Field

[0001] The utility model relates to the technical field of pluggers, in particular to a network interface plugging device. Background Art

[0002] The terminal device or host is equipped with a network port. Installing a network interface blocking device on the network port can close the network port and prevent other relevant personnel from plugging the crystal head into the network port to steal data. In most cases, for terminal devices that have been idle for a long time, the blocker is installed on the network port to prevent dust from falling into the network port and prevent the interface from being affected when it is connected and used again.

[0003] For ease of use, the Chinese patent application number 202122678054.1 discloses an idle network port and network cable sealing device, including a shell and a sealing unit. The front surface of the shell is provided with a network socket that is evenly distributed laterally, and the bottom wall of the inner cavity of the network socket is provided with contacts that are evenly distributed laterally. The sealing unit includes an installation port, a guide column and a sealing plate. The installation ports are respectively arranged at the front end of the inner cavity bottom wall of the network socket, and the inside of the installation port is slidably connected with a sealing plate, and the inner cavity bottom wall of the installation port is provided with guide columns that are symmetrically distributed laterally.

[0004] It has the following technical defects: a blocking device is formed by a large number of single components. Although it is easy to use, since the network port itself is very small, it is very difficult to assemble these single components together. In addition, the size of the single components is very small, which places high production requirements and is not conducive to mass production. Summary of the Invention

[0005] In order to solve the above problems, the utility model provides a network interface blocking device, including a plug and a key plugged into the plug;

[0006] A cavity is formed from the left side of the plug to the right, and a first insertion hole is formed from the front side of the plug to the rear, the first insertion hole is connected to the cavity front and back, and a locking portion is provided on the right side of the cavity, the locking portion is L-shaped, and the locking portion is formed by a first bent portion bent forward from the rear side of the right end of the plug and a second bent portion bent to the left from the front end of the first bent portion into the cavity. A locking hole is formed on the second bent portion, which is located in the cavity and overlaps with the rear side of the first insertion hole, and the left hole surface of the locking hole is offset backward compared to the left hole surface of the first insertion hole.

[0007] The key has a first plug-in end on its plug-in end, and the first plug-in end can be inserted into the lock hole through the first plug-in hole. When inserted, the second bent portion is pulled leftward by utilizing the offset difference between the left hole surface of the lock hole and the left hole surface of the first plug-in hole, and the first bent portion is pulled leftward by the second bent portion.

[0008] The plug and the structure on the plug are formed in one step, and the key and the structure on the key are formed in one step.

[0009] Further preferably, the first bending portion gradually tilts leftward from the front end to the rear.

[0010] Further preferably, a covering portion extending to the right is provided in front of the plug.

[0011] Further preferably, a second plug hole is opened from the front side of the plug to the rear, and the second plug hole is connected to the front and back of the cavity. A second plug end is provided on the plug end of the key. When the first plug end is inserted into the lock hole through the first plug hole, the second plug end is inserted into the cavity through the second plug hole. The second plug end is at two places, one above the other. The ends of the two second plug ends are provided with hook parts, the upper hook part is bent upward, and the lower hook part is bent downward.

[0012] Further preferably, the end of the first plug end is provided with a first chamfer, the end of the second plug end is provided with a second chamfer, the second socket is provided with a third chamfer corresponding to the second chamfer, and the lock hole is provided with a fourth chamfer corresponding to the first chamfer.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. When the plug is inserted into the mesh, its locking portion and the mesh are plugged into each other. The first bent portion will squeeze and deform the second bent portion toward the cavity. When the second bent portion is squeezed and deformed toward the cavity, it will cause the locking hole to overlap with the first insertion hole on the same straight line. Then, the other parts of the plug will be inserted into the mesh along with the locking portion. Since the locking portion is pushed into the mesh by squeezing and deformation, when the locking portion is inserted into the matching hole surface area of ​​the mesh, the first bent portion will deflect the second bent portion outward and clamp the outer side surface of the first bent portion on the hole surface in the same area as the mesh, so as to lock the entire plug into the mesh. At this time, the locking hole will also deflect outward along with the second bent portion. The locking hole and the first insertion hole are no longer on the same straight line, making it difficult to manually remove the plug from the mesh. The plug itself does not require small parts to be assembled and combined, has a simple structure, and is easy to mass produce.

[0015] 2. A key is provided for use with the plug. When the key is inserted into the plug, in addition to bringing the first plug end into the first socket of the plug, the upper and lower second plug ends are also inserted into the second sockets of the plug. The hooking parts at the ends of the second plug ends are respectively hooked on the inner surface of the plug, and the outer end of the key is pulled outward with force, thereby moving the two second plug ends outward and dragging the plug out of the mesh. The key and the various structures on the key are also formed in one step, which is convenient for mass production and is superior to the existing technology. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The following is a clear and complete description of the above and other embodiments and advantages of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments.

[0025] In one embodiment, Figure 1-Figure 7 As shown:

[0026] This embodiment provides a network interface blocking device, comprising a plug 1 and a key 2 plugged into the plug 1;

[0027] Figure 1 In the figure, the direction of the arrow indicates the direction in which the plug is pushed into the mesh of the device. The direction indicated by the arrow is the rear, and the plug is pushed into the mesh of the device from front to back. Figure 1 The directions indicated by the middle arrows describe the various parts of the plug 1. A cavity 3 is opened from the left side of the plug 1 to the right, and a first plug hole 4 is opened from the front side of the plug 1 to the rear. The first plug hole 4 is connected to the cavity 3 front and back. A locking portion 5 is provided on the right side of the cavity 3. The locking portion 5 is L-shaped. The locking portion 5 is formed in one step by a first bent portion 6 bent forward from the rear side of the right end of the plug 1 and a second bent portion 7 bent to the left from the front end of the first bent portion 6 into the cavity 3. A locking hole 8 is opened on the second bent portion 7, which is located in the cavity 3 and overlaps with the rear side of the first plug hole 4. The left hole surface of the locking hole 8 is offset backward compared to the left hole surface of the first plug hole 4.

[0028] The plug end of the key 2 is provided with a first plug end 12, which can be inserted into the lock hole 8 through the first plug hole 4. When inserted, the second bent portion 7 is pulled leftward by utilizing the offset difference between the left hole surface of the lock hole 8 and the left hole surface of the first plug hole 4, and the first bent portion 6 is pulled leftward by the second bent portion 7;

[0029] The plug 1 and the structure on the plug are formed at one time, and the key 2 and the structure on the key 2 are formed at one time.

[0030] The plug 1 is pushed into the mesh of the terminal device. The shape of the mesh is consistent with the outline of the plug 1, but the outline size of the plug 1 is larger than the outline size of the mesh. Therefore, when the plug 1 is pushed into the mesh, first, when the locking portion 5 of the plug 1 is plugged into the mesh, the first bent portion 6 will bring the second bent portion 7 to be squeezed and deformed in the direction of the cavity 3. When the second bent portion 7 is squeezed and deformed in the direction of the cavity 3, it will bring the locking hole 8 and the first insertion hole 4 to overlap on the same straight line. Secondly, the other parts of the plug 1 will also be inserted into the mesh together with the locking portion 5. Since the locking portion 5 is pushed into the mesh by squeezing and deformation, when the locking portion 5 is inserted into the matching hole surface area of ​​the mesh, the first bent portion 6 brings the second bent portion 7 to deflect outward and clamps the outer side surface (right side) of the first bent portion 6 on the hole surface corresponding to the mesh area to lock the entire plug 1 into the mesh. At this time, the lock hole 8 will also deflect outwards along with the second bent portion 7, and the lock hole 8 and the first insertion hole 4 are no longer on the same front-back straight line. At this time, it is difficult to manually remove the plug 1 from the mesh.

[0031] like Figure 1 、 Figure 2 As shown, the locking portion 5 is formed in one step by a first bent portion 6 bent forward from the rear right end of the plug 1, and a second bent portion 7 bent leftward from the front end of the first bent portion 6 into the mold cavity 3. Therefore, the plug 1 forms a self-locking structure after being inserted into the mesh by molding the locking portion 5 in a simple manner. The plug 1 itself does not require assembly of small parts, has a simple structure, and is easy to mass-produce.

[0032] like Figures 1 to 4 As shown, the front of the plug 1 is provided with a rightward-extending covering portion 9. When the plug 1 is inserted into the mesh, the second bent portion 7 expands outward and locks onto the mesh wall. The covering portion 9 then covers the front side of the second bent portion 7. Since the locking hole 8 deviates from the first insertion hole 4 (is not in a straight line), it is also covered by the covering portion 9 on the inside. At this time, it is difficult for an outsider to insert a mobile device into the mesh through the first insertion hole 4, nor is it easy to see the locking hole 8 through the first insertion hole 4. It is even more difficult for an outsider to insert a finger into the locking hole 8 and pull the second bent portion 7 toward the cavity 3, thereby loosening the plug 1. Therefore, the provision of the covering portion 9 serves to conceal the locking portion 5.

[0033] like Figures 4 to 7As shown, a second insertion hole 11 is provided from the front side of the plug 1 to the rear side. The second insertion hole 11 is connected to the cavity 3 from front to back. A second insertion end 13 is provided on the plug end of the key 2. When the first insertion end 12 is inserted into the lock hole 8 from the first insertion hole 4, the second insertion end 13 is inserted into the cavity 3 from the second insertion hole 11. The second insertion end 13 is located at two locations, one above the other. The ends of the two second insertion ends 13 are provided with hooking portions 14. The upper hooking portion 14 is bent upward, while the lower hooking portion 14 is bent downward. A first chamfer 15 is provided at the end of the first insertion end 12, a second chamfer 16 is provided at the end of the second insertion end 13, a third chamfer 17 corresponding to the second chamfer 16 is provided on the second insertion hole 11, and a fourth chamfer 18 corresponding to the first chamfer 15 is provided on the lock hole 8.

[0034] In order to remove the plug 1 from the device mesh, a key 2 is also provided. Figures 5 to 7 As shown, insert the key 2 into the plug 1, and then drag the key 2 outward to pull the plug 1 out of the mesh. Since the plug 1 needs to be pulled out of the mesh through the key 2, the first hole 4 is very small, so the first plug end 12 on the key 2 is also very thin. The first hole 4 is designed to be very small, which makes it difficult for the plug 1 to be easily pulled out by the fingers when inserted into the mesh. When the key 2 is inserted into the plug 1, the middle first plug end 12 is inserted into the first hole 4. As the key 2 continues to advance, the first chamfer 15 at the end of the first plug end 12 is squeezed and pushed along the fourth chamfer 18 on the lock hole 8, so that the hole surface of the lock hole 8 is subjected to force, and the second bending portion 7 is pulled by the hole surface of the lock hole 8, so that the second bending portion 7 is biased toward the cavity 3, so as to pull the locking portion 5 out of the hole surface structure of the equipment mesh. At this time, the locking force of the plug 1 in the mesh disappears. In order to be able to pull the plug 1 out of the mesh through the key 2, in addition to the first plug end 12 formed on the key 2, two upper and lower second plug ends 13 are also formed on the key 2, and the ends of these two second plug ends 13 are both provided with hook portions 14.

[0035] When the key 2 is inserted into the plug 1, in addition to bringing the first plug end 12 into the first socket 4 of the plug 1, it will also bring the upper and lower second plug ends 13 into the second socket 11 of the plug 1. As the key 2 continues to advance, the two second plug ends 13 will push the second chamfer 16 at the end and enter the second socket 11 along the second chamfer 16. At this time, the hooking parts 14 at the ends of the two second plug ends 13 are respectively hooked on the inner surface of the plug 1, pulling the outer end of the key 2 outward with force, thereby moving the two second plug ends 13 outward, and the two second plug ends 13 move the hooking parts 14 outward, dragging the plug 1 out of the mesh.

[0036] In summary, the key 2 and the various structures on the key 2 are also formed in one step, which is convenient for mass production and is superior to the existing technology.

[0037] The above orientation designations do not represent the specific orientations of the components in this implementation scheme. This implementation scheme is only for the convenience of describing the scheme, and the orientations are described relatively with reference to the figures. In essence, the specific orientations of the components are described based on their actual installation and actual use, as well as the customary orientations of those skilled in the art. This is hereby explained.
