DETAILED DESCRIPTION

[0033] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0034] A specific embodiment of the utility model is as follows Figure 1 As shown, a pull-ring type key-destroying trigger device is disclosed, comprising a key-destroying body 1, an external shell 2 and a trigger structure 3.

[0035] The outer shell 2 has a cavity inside, and the trigger structure 3 is arranged in the cavity. The key destroying body 1 is arranged in the center of the shell and the trigger structure 3. The front of the outer shell 2 and the trigger structure 3 forms a through hole that can pass through the key destroying body 1, which is used to accommodate the key destroying body 1.

[0036] The key destroying body 1 comprises a panel 101 , a key destroying main rod 102 and a pull ring 103 .

[0037] A pull ring 103 is embedded in the front of the panel 101. The pull ring 103 is a semicircular ring structure, and the outer edge of the pull ring 103 is on the same circle as the outer edge of the panel 101. When not in use, the pull ring 103 is on the same plane as the panel 101. When in use, in order to facilitate the pull ring 103 to be unscrewed, so that a hand can be inserted into the pull ring 103 to pull the pull ring 103, a rotating shaft 1011 is provided in the panel 101, and the two ends of the pull ring 103 are fixed to the two ends of the rotating shaft 1011, and the pull ring 103 can rotate around the rotating shaft 1011. At the same time, the pull ring 103 is connected to the panel 101 through the rotating shaft 1011.

[0038] One end of the key-destroying main rod 102 is fixed to the panel 101, and the other end extends into the trigger structure 3. It can be understood that when the pull ring 103 is pulled outward, the pull ring 103 pulls the panel 101 outward, and the panel 101 drives the key-destroying main rod 102 to move outward, so that the key-destroying main rod 102 can be extended into or pulled out of the trigger structure 3.

[0039] The outer shell 2 is used to protect the key body 1 and the trigger device inside, and connect external devices. The outer shell 2 includes two parts, one is a cylindrical head 201, and the other is a square shell body 202.

[0040] The head 201 is arranged at the front of the outer shell 2. The front of the head 201 has a groove for accommodating the panel 101 of the key body 1. In order to facilitate the hand pulling of the pull ring 103 from the position coplanar with the panel 101, a hand grip groove 2012 is arranged below the position of the head 201 corresponding to the pull ring 103. When using the pull ring 103, the hand is placed in the hand grip groove 2012 to pull up the pull ring 103.

[0041] In order to avoid pulling out the pull ring 103 by mistake and causing unnecessary losses, Figure 2 As shown, a limiting structure is provided. The limiting structure includes a limiting groove 2011, a pin body 1012 and a nut. A limiting groove 2011 for limiting the pulling of the pull ring 103 is provided at the rear of the head 201, and the limiting groove 2011 is an arc-shaped groove. A pin body 1012 is provided at the rear of the panel 101 of the key destroying body 1, and a nut is installed at the end of the pin body 1012. It should be noted that the width of the limiting groove 2011 is greater than the diameter of the pin body 1012 and smaller than the diameter of the nut. The pin body 1012 can move in the limiting groove 2011 but cannot be pulled out. A circular hole is provided at the end of the limiting groove 2011, and the circular hole is connected to the limiting groove 2011. The diameter of the circular hole is greater than the diameter of the nut, and is used to rotate the pin body 1012 to this position to pull out the pull ring 103 when destroying the key. During installation, the pin body 1012 is installed at the starting end of the limiting groove 2011 . At this time, the pull ring 103 is located on the inner side of the hand buckle groove 2012 .

[0042] Two square protrusions are arranged on both sides of the exterior of the housing body 202, and threaded holes are arranged on the protrusions for connecting the device to an external device to be destroyed.

[0043] The housing body 202 includes an upper cover and a lower cover. The upper cover and the lower cover are connected by screws. There are protrusions on both sides of the inner part of the upper cover of the housing, and the two protrusions are located opposite to each other, and the trigger structure 3 is fixed in the middle. Screws are provided on the lower cover for installing the trigger structure 3.

[0044] like Figure 3 and Figure 4 As shown, a circular through hole is provided at the front of the housing body 202 for mounting the trigger structure 3 .

[0045] The trigger structure 3 is used to combine with the key destruction body 1 to realize the key destruction state. The signal of the key destruction state is transmitted to the external software for recognition and execution of key destruction. The trigger structure 3 includes a housing 301, a spring, a spring and a contact piece.

[0046] The part where the shell 301 connects with the circular through hole is a cylindrical structure with a through hole in the middle for inserting the key destroying main rod 102. The main body of the shell 301 is square, and a spring, a spring sheet and a contact sheet are arranged inside. In order to prevent the key destroying main rod 102 from being driven out when the pull ring 103 is pulled out, the width of the square shell is greater than the diameter of the circular through hole.

[0047] A groove is provided on the wall surface at the entrance of the square shell, and a fixed elastic fixing piece 302 is installed in the groove; a round hole is provided in the middle of the elastic fixing piece 302 for passing through and fixing the key-destroying main rod 102 to keep the key-destroying main rod 102 centered.

[0048] A cavity is formed inside the square shell. Springs, springs and contact pieces are respectively arranged on opposite sides of the cavity of the trigger structure 3 to achieve two states: key-destroying and normal.

[0049] A protrusion is provided inside the cavity of the trigger structure 3, and the protrusion and the wall surface form a hook structure. The spring is an arc-shaped piece. The spring includes a hook-shaped end and a suspension end. The hook-shaped end can hook the hook structure. It should be noted that the width of the hook structure is greater than the thickness of the spring, and the hook-shaped end of the spring can swing in the hook structure. A contact piece is provided outside the suspension end. A spring is provided at one end of the spring close to the suspension, and the other end of the spring is fixed to the side wall of the cavity of the trigger structure 3.

[0050] The spring piece has an outwardly protruding section, which can rest on the key-destroying main rod 102 when the key-destroying main rod 102 is inserted. Figure 3 As shown in the figure, under the action of the lever, the suspended end of the spring is lifted and does not contact the contact piece. This is the normal state, and the spring is compressed. Figure 4 As shown, when the key-destroying main rod 102 is pulled out, the spring returns to its free length, and the suspended end of the spring moves outward under the action of the spring and contacts the contact piece, which is the key-destroying state.

[0051] The spring includes a first spring 303-1 and a second spring 303-2, the spring includes a first spring 304-1 and a second spring 304-2, and the contact includes a first contact 305-1 and a second contact 305-2. The first spring 303-1, the first spring 304-1, the first contact 305-1 and the second spring 303-2, the second spring 304-2, the second contact 305-2 are disposed on both sides of the cavity of the trigger structure 3.

[0052] At the end position of the key-destroying main rod 102, a limiting block 306 is provided inside the cavity of the trigger structure 3 to limit the position of the key-destroying main rod 102 when it is extended.

[0053] Compared with the prior art, the trigger structure 3 in this embodiment is provided with a spring, a spring sheet and a contact sheet. A hook-shaped structure is constructed on the side wall of the cavity of the trigger structure 3 to hang one end of the spring sheet and suspend the other end of the spring sheet. Whether the key is destroyed is determined by whether the suspended end of the spring sheet contacts the contact sheet. An outward protrusion is provided on the spring sheet so as to overlap the key-destroying main rod 102, so that the suspended end is tilted and does not contact the contact sheet. When the suspended end needs to contact the contact sheet, the key-destroying main rod 102 is withdrawn. The switching between the two states is achieved by the extension and withdrawal of the key-destroying main rod 102.

[0054] The method of using this embodiment is as follows:

[0055] Without connecting electricity, the key destroying body 1 is passed through the through holes between the shell and the trigger structure 3 in sequence until the end of the key destroying main rod 102 contacts the limit block 306. It should be noted during installation that, in the initial state, the pin body 1012 at the rear of the panel 101 of the key destroying body 1 is placed at the starting end of the arc groove, and a nut is screwed on the end of the pin body 1012. At this time, the panel 101 of the key destroying body 1 is embedded in the panel 101 of the shell, and the pull ring 103 is embedded in the panel 101 of the key destroying body 1, and is coplanar with the panel 101 of the key destroying body 1. The pull ring 103 is located on the inner side of the hand buckle groove 2012 on the head 201.

[0056] After the key-destroying main rod 102 is inserted, the raised sections of the spring pieces on both sides of the cavity of the trigger structure 3 are placed on the key-destroying main rod 102, the spring is compressed, and the suspended end of the spring piece is tilted and does not contact the contact piece.

[0057] When the key needs to be destroyed, when the circuit is connected, take the pull ring 103 from the buckle groove 2012, rotate the pull ring 103 to the direction perpendicular to the key destruction panel 101, and rotate the key destruction panel 101 so that the pin body 1012 with the nut rotates from the starting end of the arc groove to the end hole of the arc groove. Pull the pull ring 103 outward to bring out the key destruction main rod 102. After the key destruction main rod 102 is pulled out, the spring stretches to the natural state, and the suspended end of the spring contacts the contact piece, which is the key destruction state. After the key destruction state is transmitted to the external software for recognition, the key destruction of the device connected to the device is triggered.

[0058] Compared with the prior art, this embodiment uses a pull ring 103 to pull the panel 101, bringing out the key-destroying main rod 102, so that the trigger structure 3 is in a key-destroying state, and the state is identified by external software, thereby realizing a key-destroying method for an external device, which has a simple structure and is easy to implement.

[0059] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
