Description

Technical Field

[0001] The utility model relates to the technical field of computers, in particular to a pull-out locking device and a computer. Background Art

[0002] With the rapid development of technology, some functional modules on computers are usually installed on the chassis using a pull-out locking device design to facilitate replacement or maintenance of the functional modules.

[0003] Network security machines, also known as network security devices, are a type of industrial computer widely used for information security protection, including firewalls, behavior management and auditing, VPNs (virtual private networks), vulnerability scanning, and gateways. The network module is also known as a NIC (Network Interface Card) or ENS (Ethereum Name Service) module.

[0004] A network security machine typically comes with 4-8 network modules. Network modules in the industry typically use a pull-out locking mechanism to connect to the chassis, facilitating module replacement. However, existing pull-out locking mechanisms require screws to secure the network module to the chassis. To remove a network module, the operator must carry a screwdriver to remove the screws and then pull the module out of the chassis, making this operation very inconvenient. Utility Model Content

[0084] Example 1

[0085] This embodiment provides a pull-out locking device. Figure 1 、 Figure 2 and Figure 3 The pull-out locking device includes a lock body assembly 1 and a lock box 2. The lock body assembly 1 can be pushed into the lock box 2 along the inward pushing direction or separated from the lock box 2 along the outward pulling direction. The inward pushing direction is opposite to the outward pulling direction.

[0086] It should be noted that the lock body assembly 1 is pushed into the lock box 2 along the inward pushing direction, which means that the lock body assembly 1 is partially or completely inserted into the lock box 2. In this embodiment, the lock body assembly 1 is pushed into the lock box 2 along the inward pushing direction, which means that the lock body assembly 1 is partially inserted into the lock box 2.

[0087] Combine Figure 2 and Figure 4The lock assembly 1 includes a lock support 11, a locking push pin 12, and a push-pull pin 13. The locking push pin 12 is located on the side of the lock support 11 facing the inward push direction and is fixedly connected to the lock support 11. The push-pull pin 13 is located on the side of the lock support 11 facing the inward push direction and is movably connected to the lock support 11.

[0088] Combine Figure 3 and Figure 5 The lock box 2 includes a housing 21, a first locking tongue 22, a second locking tongue 23, and a clamping elastic member 24. The housing 21 is fixedly mounted on the side of the lock body bracket 11 facing the inward push direction. The clamping elastic member 24, the first locking tongue 22, and the second locking tongue 23 are all connected to the housing 21. The first locking tongue 22 is located on the side of the second locking tongue 23 facing the first clamping direction. The first clamping direction intersects the inward push direction.

[0089] The housing 21 can be a box 211, such as a hexagonal box 211, or a frame, such as a square frame. The angle between the first clamping direction and the inward-pushing direction can be either acute or right. In this embodiment, the housing 21 is a hexagonal box 211. The first clamping direction is perpendicular to the inward-pushing direction, and the first clamping direction is upward, the inward-pushing direction is rearward, and the outward-pushing direction is forward. The clamping elastic member 24 is a compression spring.

[0090] The clamping elastic member 24 is connected to the first locking tongue 22 and / or the second locking tongue 23 respectively, and is used to drive the first locking tongue 22 and the second locking tongue 23 to move closer to each other.

[0091] Combine Figure 6 、 Figure 7 and Figure 8 When the lock body assembly 1 is pushed into the lock box 2 along the inward pushing direction, the first lock tongue 22 and the second lock tongue 23 clamp the positioning push pin 12 and the push-pull pin 13 through the clamping elastic member 24. The end of the positioning push pin 12 facing the inward pushing direction is located on the side of the first lock tongue 22 facing the inward pushing direction, and abuts against the first lock tongue 22 and / or the second lock tongue 23 along the outward pulling direction. The end of the push-pull pin 13 facing the inward pushing direction is located on the side of the first lock tongue 22 facing the inward pushing direction.

[0092] Combine Figure 9 、 Figure 10 and Figure 11 When the lock body assembly 1 changes from being pushed into the lock box 2 to being out of the lock box 2, the push-pull pin 13 moves in the outward withdrawal direction, and the push-pull pin 13 pushes the first lock tongue 22 and the second lock tongue 23 away from each other, so as to release the engagement of the locking push pin 12 with the first lock tongue 22 and / or the second lock tongue 23 in the outward withdrawal direction, so that the locking push pin 12 can move in the outward withdrawal direction.

[0093] When the lock body assembly 1 is separated from the lock box 2 along the outward withdrawal direction, the push-pull pin 13 and the locking pin 12 are both located on the side of the first lock tongue 22 facing the outward withdrawal direction.

[0094] The pull-out locking device and computer provided in this embodiment have a simple structure. The locking push pin 12 and the push-pull pin 13 cooperate with the lock box 2. When the lock body assembly 1 is pushed into the lock box 2 along the inward pushing direction, the lock body bracket 11 is in a locked state. At this time, the end of the locking push pin 12 facing the inward pushing direction abuts against the first lock tongue 22 and / or the second lock tongue 23 along the outward pulling direction. The first lock tongue 22 and / or the second lock tongue 23 abuts against the locking push pin 12 to block the locking push pin 12 from moving along the outward pulling direction, thereby locking the lock body bracket 11.

[0095] When the lock body assembly 1 needs to be changed from being pushed into the lock box 2 to being separated from the lock box 2, that is, in the process of changing the lock body bracket 11 from the locked state to the unlocked state, the push-pull pin 13 is first pushed in the outward withdrawal direction, so that the first lock tongue 22 and the second lock tongue 23 are separated from each other, so as to release the abutment of the locking push pin 12 with the first lock tongue 22 and / or the second lock tongue 23 in the outward withdrawal direction. Then, the push-pull pin 13 and the locking push pin 12 can be separated from the lock box 2 together with the lock body bracket 11, so that the lock body bracket 11 is in the unlocked state, thereby achieving the separation of the lock body assembly 1 from the lock box 2. It can be seen that in the process of changing the lock body bracket 11 from the locked state to the unlocked state, the lock body bracket 11 can be quickly disassembled by only driving the push-pull pin 13 and the locking push pin 12 in sequence in the outward withdrawal direction.

[0096] It can be understood that the number of locking pins 12 and push-pull pins 13 can be the same or different, and can be one or more; the plane where the push-pull pins 13 and the locking pins 12 are located, the surface of the first lock tongue 22 facing the second lock tongue 23, and the surface of the second lock tongue 23 facing the first lock tongue 22 are all perpendicular to the first clamping direction; one of the first lock tongue 22 and the second lock tongue 23 can be fixedly connected to the shell 21, and the other can be movably connected to the shell 21, and the clamping elastic member 24 is only connected to the first lock tongue 22 or the second lock tongue 23 movably connected to the shell 21.

[0097] Furthermore, taking the example that the first lock tongue 22 and the second lock tongue 23 are both movably connected to the shell 21, the first lock tongue 22 and the second lock tongue 23 can both be wedge-shaped structures, and the narrow ends of the first lock tongue 22 and the second lock tongue 23 are arranged relative to each other. In this way, when the positioning push pin 12 moves along the inward pushing direction and drives the first lock tongue 22 and the second lock tongue 23 away from each other, the positioning push pin 12 applies an upward force to the first lock tongue 22 and a downward force to the second lock tongue 23. The surface of the rear end of the positioning push pin 12 that contacts the first lock tongue 22 and the second lock tongue 23 can be an inclined surface adapted to the first lock tongue 22 and the second lock tongue 23, or it can be a curved surface. Similarly, in the process of the push-pull pin 13 moving in the outward direction and driving the first lock tongue 22 and the second lock tongue 23 away from each other, the push-pull pin 13 exerts an upward force on the first lock tongue 22 and a downward force on the second lock tongue 23. The surface of the rear end of the push-pull pin 13 that contacts the first lock tongue 22 and the second lock tongue 23 can be an inclined surface adapted to the first lock tongue 22 and the second lock tongue 23, or it can be a curved surface.

[0098] In this embodiment, the first lock tongue 22 and the second lock tongue 23 are both movably connected to the shell 21; the length directions of the push-pull pin 13 and the locking push pin 12 are consistent with the inward pushing direction, that is, the push-pull pin 13 and the locking push pin 12 are both long strip structures extending along the front-to-back direction; the number of locking push pins 12 and push-pull pins 13 is the same, and the number is two; the lower surface of the first lock tongue 22 and the upper surface of the second lock tongue 23 are both flush with the horizontal plane, but are not limited to this; the two locking push pins 12 and the push-pull pin 13 are both located on the same horizontal plane, wherein the two locking push pins 12 are located between the two push-pull pins 13; one end of the clamping elastic member 24 abuts against the first lock tongue 22 and the second lock tongue 23 respectively, and the other end of the clamping elastic member 24 abuts against the shell 21.

[0099] Specific, combined Figure 12 and 13The upper surface of the first lock tongue 22 is provided with an upper positioning groove 221, and the lower surface of the second lock tongue 23 is provided with a lower positioning groove 231. The upper positioning groove 221 and the lower positioning groove 231 correspond to the clamping elastic members 24 one by one. In this embodiment, the number of the clamping elastic members 24 is four, of which two clamping elastic members 24 are located above the first lock tongue 22, and the bottom ends of the two clamping elastic members 24 are inserted into the corresponding upper positioning groove 221 and abut against the first lock tongue 22, and the top ends of the two clamping elastic members 24 abut against the shell 21 respectively; the other two clamping elastic members 24 are located below the second lock tongue 23, and the top ends of the two clamping elastic members 24 are removed into the corresponding lower positioning groove 231 and abut against the second lock tongue 23, and the bottom ends of the two clamping elastic members 24 abut against the shell 21 respectively. The upper positioning groove 221 and the lower positioning groove 221 are provided to facilitate the installation of the clamping elastic member 24 and also ensure the stability of the first locking tongue 22 and the second locking tongue 23 .

[0100] Further, combined Figure 6 、 Figure 7 and Figure 8 When the lock body assembly 1 changes from being out of the lock box 2 to being pushed into the lock box 2, the locking push pin 12 moves in the inward pushing direction, and the locking push pin 12 pushes the first lock tongue 22 and the second lock tongue 23 away from each other. The push-pull pin 13 moves in the inward pushing direction, and the end of the push-pull pin 13 facing the inward pushing direction passes through the opening between the first lock tongue 22 and the second lock tongue 23.

[0101] Thus, when the lock body assembly 1 needs to be changed from being disengaged from the lock box 2 to being pushed into the lock box 2, that is, when the lock body bracket 11 is changed from the unlocked state to the locked state, the push-pull pin 13 is first pushed in the outward pulling direction, so that the first lock tongue 22 and the second lock tongue 23 are separated from each other, so that the rear end of the positioning push pin 12 can smoothly pass through the first lock tongue 22 and the second lock tongue 23 in the inward pushing direction, and then the rear end of the push-pull pin 13 and the rear end of the positioning push pin 12 can pass through the first lock tongue 22 and the second lock tongue 23, so that the lock body bracket 11 is in the locked state, thereby achieving the installation and fixation of the lock body bracket 11. In this way, the lock body bracket 11 can be installed and fixed by only pushing the lock body assembly 1 in the inward pushing direction, which is simple to operate.

[0102] Combine Figure 4 and Figure 14 The lock body assembly 1 further includes: a handle 14 and a handle 15. Figure 15 、 Figure 16 and Figure 17 The handle 14 is slidably connected to the lock body bracket 11 along the inward pushing direction and the outward pulling direction and is fixedly connected to the push-pull pin 13. The handle 15 is located on the side of the lock body bracket 11 facing the outward pulling direction and is fixedly connected to the lock body bracket 11.

[0103] It is understandable that the pull handle 14 and the handle 15 can be arranged at the front end of the lock body bracket 11 along the left-right direction, or can be arranged at the front end of the lock body bracket 11 along the up-down direction.

[0104] In this embodiment, combined with Figure 4 and Figure 18 The handle 15 is C-shaped, with a first mounting slot 151 formed on its inner sidewall. The pull handle 14 is located on the inner side of the handle 15 and fits into the first mounting slot 151. The pull handle 14 is movably connected to the handle 15. The rear ends of the handle 15 are inserted into the left and right ends of the lock body bracket 11 and are fixed to the lock body bracket 11 via side screws. The rear ends of the pull handle 14 pass through the left and right ends of the lock body bracket 11 and are fixed to the push-pull pin 13.

[0105] By limiting the relative positions of the handle 14 and the handle 15 , not only is the space utilization of the pull-out locking device improved, but also one-handed operation can be achieved, thereby improving the convenience of disassembly and assembly of the lock body bracket 11 .

[0106] Combine Figure 4 and Figure 19 The lock assembly 1 further includes an inner locking block 16. The inner locking block 16 is located on the side of the lock body bracket 11 facing the inward push direction and is fixedly connected to the handle 14 and the push-pull pin 13. The inner locking block 16 is used to constrain the end of the handle 14 facing the inward push direction to the side of the lock body bracket 11 facing the inward push direction.

[0107] It is understood that the locking push pin 12 and the inner locking block 16 can be arranged in an up-and-down manner on the rear side of the lock body bracket 11. In this embodiment, the main body of the inner locking block 16 is a plate-like structure, with the left and right ends of the inner locking block 16 being block-like structures that extend in the outward direction and are fixedly connected via the corresponding rear ends of the screw handle 14; the front ends of the two push-pull pins 13 are fixed to the rear surface of the inner locking block 16 via screws, and the inner locking block 16 has two through-holes 161 adapted to the locking push pins 12 between the two push-pull pins 13. The front end of the locking push pin 12 is fixedly connected to the lock body bracket 11 via screws, and the rear end of the locking push pin 12 passes through the inner locking block 16 via the corresponding through-holes 161.

[0108] So, combined Figure 6 and Figure 9 When the handle 14 is driven to move relative to the handle 15, the push-pull pin 13 can move synchronously with the handle 14 relative to the locking push pin 12. The provision of the inner locking block 16 not only prevents the handle 14 from completely separating from the lock body bracket 11, but also provides a larger connection position for the push-pull pin 13, making it easier for the push-pull pin 13 to adapt to the first lock tongue 22 and the second lock tongue 23.

[0109] In this embodiment, combined with Figure 19The through-hole 161 is rectangular in shape, and the front end of the locking push pin 12 has a rectangular cross-section that matches the through-hole 161. The rear end of the locking push pin 12 is a shaft structure that matches the through-hole 161, but this is not limited to this. During the movement of the locking push pin 12 relative to the inner locking block 16, the front end of the locking push pin 12 remains within the through-hole 161. By restricting the shape of the locking push pin 12, it is effectively prevented from rotating along its own axis, thereby affecting the performance of the lock assembly 1.

[0110] The inner locking block 16 is also fixedly provided with second stopper protrusions 162 on its surface facing the inward push direction. These second stopper protrusions 162 are located on the left and right sides of the corresponding push-pull pin 13. The provision of these second stopper protrusions 162 facilitates installation of the push-pull pin 13. The lock body bracket 11 is also fixedly provided with third stopper protrusions 111 on its surface facing the inward push direction. These third stopper protrusions 111 are located on the left and right sides of the corresponding locking push pin 12. The provision of these third stopper protrusions 111 facilitates installation of the locking push pin 12.

[0111] Combine Figure 4 、 Figure 15 and Figure 18 The lock body assembly 1 further includes a reset elastic member 17 . One end of the reset elastic member 17 is connected to the handle 14 , and the other end of the reset elastic member 17 is connected to the lock body bracket 11 , for applying a force on the handle 14 in an inward pushing direction.

[0112] The other end of the reset elastic member 17 can be directly connected to the lock body bracket 11, or directly connected to the handle 15. When the other end of the reset elastic member 17 is directly connected to the lock body bracket 11, the reset elastic member 17 is located on the side of the lock body bracket 11 facing the inward pushing direction, and one end of the reset elastic member 17 is connected to the inner lock block 16.

[0113] In this embodiment, the reset elastic member 17 is a telescopic spring and there are two of them. The two reset elastic members 17 are both located in the first mounting groove 151 in front of the handle 14, and the front ends of the two reset elastic members 17 are in conflict with the handle 15, and the rear ends of the two reset elastic members 17 are in conflict with the front end of the handle 14.

[0114] Among them, the handle 15 is fixed with two front end protrusions 152 on the bottom wall facing the rear of the first installation groove 151, and the front ends of the two reset elastic members 17 are respectively sleeved on the outer sides of the corresponding front end protrusions 152; Figure 15 and Figure 20A second mounting groove 143 is formed on the outer side wall of the handle 14, and two rear end protrusions 141 are fixedly provided on the bottom wall of the handle 14 facing forward of the second mounting groove 143, and the rear ends of the two reset elastic members 17 are respectively sleeved on the outer sides of the corresponding rear end protrusions 141; four first limiting protrusions 142 are fixedly provided on the bottom wall of the handle 14 facing forward of the second mounting groove 143, and the four first limiting protrusions 142 and the side walls of the handle 14 form two independent cavities, and the two rear end protrusions 141 and the rear ends of the two reset elastic members 17 are respectively located in the corresponding cavities.

[0115] By providing the front end protrusion 152 , the rear end protrusion 141 and the first limiting protrusion 142 , the reset elastic member 17 can be effectively limited to prevent the reset elastic member 17 from being displaced when the handle 15 and the handle 14 compress the reset elastic member 17 , thereby affecting the reset of the handle 14 .

[0116] It should be noted that the push-pull pin 13 drives the first lock tongue 22 and the second lock tongue 23 away from each other, which can be achieved by setting a bevel at the position corresponding to the rear end of the push-pull pin 13 or / and setting a bevel at the ends of the first external pull-out groove 223 and the second external pull-out groove 233.

[0117] Combine Figure 16 and Figure 21 The push-pull pin 13 has a first groove on its surface facing the first clamping direction, and a second groove on its surface facing the second clamping direction. The second clamping direction is opposite to the first clamping direction. The push-pull pin 13 has outward-drawing guide slopes 132 on the sidewalls of both the first and second grooves facing the inward push direction.

[0118] When the lock body assembly 1 is pushed into the lock box 2 in the inward pushing direction, the first lock tongue 22 is inserted into the first groove, and the second lock tongue 23 is inserted into the second groove. When the lock body assembly 1 changes from being pushed into the lock box 2 to being separated from the lock box 2, the push-pull pin 13 pushes the first lock tongue 22 and the second lock tongue 23 away from each other via the outward pulling guide slope 132.

[0119] By providing an outward-pulling guide inclined surface 132 on the push-pull pin 13, the first lock tongue 22 and the second lock tongue 23 can be guided when the push-pull pin 13 moves in the outward-pulling direction, so that the first lock tongue 22 and the second lock tongue 23 can move away from each other at the same time, thereby releasing the restriction of the first lock tongue 22 and the second lock tongue 23 on the locking push pin 12.

[0120] It is understood that the first groove and the second groove can be flat bottom grooves or arc bottom grooves coaxial with the push-pull pin 13. In this embodiment, the first groove and the second groove are connected to each other and form an annular groove 131 around the rear end of the push-pull pin 13. Figure 21 .

[0121] In a further alternative embodiment of this embodiment, only the first groove or the second groove may be provided on the side wall of the push-pull pin 13. For example, when the second locking tongue 23 is fixedly connected to the housing 21 and the first locking tongue 22 is movably connected to the housing 21, the push-pull pin 13 may only have the first groove and be provided with an outward-drawing guide inclined surface 132 on the first groove, but this is not limited to this and is not specifically limited in this embodiment.

[0122] In this embodiment, combined with Figure 5 、 Figure 7 and Figure 8 The first lock tongue 22 and the second lock tongue 23 are both long strip structures. Figure 5 and Figure 22 A guide hole structure is provided at one end of the first lock house 22 toward the second lock tongue 23 or / and at one end of the second lock tongue 23 toward the first lock tongue 22, so that the positioning push pin 12 or the push-pull pin 13 drives the first lock tongue 22 and the second lock house 23 away from each other through the guide hole structure.

[0123] Specific, combined Figure 22 and Figure 23 A first outward-drawing groove 223 is defined on the surface of the first locking tongue 22 facing the second clamping direction. The first outward-drawing groove 223 extends through the first locking tongue 22 in the outward-drawing direction. A second outward-drawing groove 233 is defined on the surface of the second locking tongue 23 facing the first clamping direction. The second outward-drawing groove 233 extends through the second locking tongue 23 in the outward-drawing direction. The second outward-drawing groove 233 overlaps with the first outward-drawing groove 223 in the first clamping direction.

[0124] It can be understood that the first outer groove 223 corresponds to the second outer groove 233 one by one, and the number and arrangement of the first outer groove 223 and the second outer groove 233 are consistent with the number and arrangement of the push-pull pin 13. When the first lock tongue 22 and the second lock tongue 23 are in contact with each other, the first outer groove 223 and the corresponding second outer groove 233 form a through hole, and the diameter of the through hole is smaller than the diameter of the rear end of the push-pull pin 13. Figure 7 .

[0125] Combine Figure 7 When the lock body assembly 1 is pushed into the lock box 2 along the inward pushing direction, the first lock tongue 22 clamps the push-pull pin 13 through the first outward withdrawal groove 223, and the second lock tongue 23 clamps the push-pull pin 13 through the second outward withdrawal groove 233. When the lock body assembly 1 changes from being pushed into the lock box 2 to being separated from the lock box 2, the push-pull pin 13 passes through the first lock tongue 22 through the first outward withdrawal groove 223 and passes through the second lock tongue 23 through the second outward withdrawal groove 233.

[0126] At the same time, in this embodiment, combined with Figure 7 and Figure 23The first locking tongue 22 has a first outward auxiliary inclined surface 224 at one end of the first outward groove 223 facing the inward pushing direction, and the second locking tongue 23 has a second outward auxiliary inclined surface 234 at one end of the second outward groove 233 facing the inward pushing direction.

[0127] When the push-pull pin 13 moves in the outward direction and drives the first lock tongue 22 and the second lock tongue 23 away from each other, the outward guide inclined surface 132 on the push-pull pin 13 respectively fits with the first outward auxiliary inclined surface 224 on the first lock tongue 22 and the second outward auxiliary inclined surface 234 on the second lock tongue 23 to push the first lock tongue 22 and the second lock tongue 23 away from each other.

[0128] In this embodiment, combined with Figure 17 and Figure 24 The surface of the locking push pin 12 facing the first clamping direction is provided with a first slot, and the surface of the locking push pin 12 facing the second clamping direction is provided with a second slot. The end of the locking push pin 12 facing the inward pushing direction is provided with a first inward pushing guide slope 122 and a second inward pushing guide slope 122. The first inward pushing guide slope 122 and the second inward pushing guide slope 122 can be two plane or arc-shaped slopes.

[0129] It is understandable that the first and second slots can be flat bottom slots or arc bottom slots coaxial with the push-pull pin 13. In this embodiment, the first and second slots are interconnected to form an annular slot 121 surrounding the rear end of the push-pull pin 13.

[0130] In a further optional embodiment of this embodiment, only the first or second slots may be provided on the side wall of the locking push pin 12. For example, when the second locking tongue 23 is fixedly connected to the housing 21 and the first locking tongue 22 is movably connected to the housing 21, the locking push pin 12 may only have the first slot, so that the lock box 2 can lock the lock body assembly 1 through the engagement between the first locking tongue 22 and the locking push pin 12. At the same time, the rear end of the locking push pin 12 is provided with an inward-pushing guide slope 122 facing the first locking tongue 22. When the locking push pin 12 moves in the inward-pushing direction and drives the first locking tongue 22 and the second locking tongue 23 away from each other, the inward-pushing guide slope 122 abuts against the first locking tongue 22, thereby applying an upward force on the first locking tongue 22.

[0131] In this embodiment, combined with Figure 8 、 Figure 17 and Figure 24The end of the locking push pin 12 facing the inward pushing direction is provided with an inward pushing guide slope 122, which is an annular slope, including the first inward pushing guide slope 122 and the second inward pushing guide slope 122 mentioned above. The first inward pushing guide slope 122 is located on the side of the second inward pushing guide slope 122 facing the first clamping direction, that is, the locking push pin 12 is used to abut against the first lock tongue 22 through the first inward pushing guide slope 122, and abut against the second lock tongue 23 through the second inward pushing guide slope 122; the locking push pin 12 pushes the first lock tongue 22 and the second lock tongue 23 away from each other through the inward pushing guide slope 122. The side walls of the locking push pin 12 in the first slot and the second slot facing the inward pushing direction are perpendicular to the outward pulling direction, but it is not limited to this. For example, when the first slot and the second slot are dovetail slots, the side walls of the locking push pin 12 in the first slot and the second slot facing the inward pushing direction are inclined. At this time, the side walls of the locking push pin 12 in the first slot and the second slot facing the inward pushing direction intersect with the outward pulling direction.

[0132] When the lock body assembly 1 is pushed into the lock box 2 in the inward pushing direction, the first locking tongue 22 is inserted into the first locking groove, and the second locking tongue 23 is inserted into the second locking groove. In this way, the locking push pin 12 is engaged with the first locking tongue 22 and the second locking tongue 23 in the outward pulling direction, thereby preventing the locking push pin 12 from being separated from the lock box 2 in the outward pulling direction.

[0133] When the lock body assembly 1 changes from being separated from the lock box 2 to being pushed into the lock box 2, the locking push pin 12 pushes the first lock tongue 22 and the second lock tongue 23 away from each other via the first inner push guide slope 122 and the second inner push guide slope 122. In this way, the rear end of the push-pull pin 13 can pass through the first lock tongue 22 and the second lock tongue 23 via the corresponding first outer withdrawal groove 223 and the second outer withdrawal groove 233 when the locking push pin 12 separates the first lock tongue 22 and the second lock tongue 23.

[0134] In this embodiment, combined with Figure 10 、 Figure 15 and Figure 23 The push-pull pin 13 has an annular inward push inclined surface 133 at its end facing the inward push direction. The first locking tongue 22 has a third inward push auxiliary inclined surface 226 at one end facing the outward pull direction of the first outward pull groove 223. The second locking tongue 23 has a fourth inward push auxiliary inclined surface 236 at one end facing the outward pull direction of the second outward pull groove 233.

[0135] The inward push inclined surface 133 can facilitate the rear end of the push-pull pin 13 to accurately and quickly pass through the first lock tongue 22 and the second lock tongue 23 after the locking push pin 12 separates the first lock tongue 22 and the second lock tongue 23.

[0136] Combine Figure 22 and Figure 25The first locking tongue 22 has a first inward-pushing groove 222 defined on its surface facing the second clamping direction. The first inward-pushing groove 222 extends through the first locking tongue 22 in the inward-pushing direction. The second locking tongue 23 has a second inward-pushing groove 232 defined on its surface facing the first clamping direction. The second inward-pushing groove 232 extends through the second locking tongue 23 in the inward-pushing direction, wherein the second inward-pushing groove 232 overlaps with the first inward-pushing groove 222 in the first clamping direction.

[0137] It is understood that the first inward pushing grooves 222 and the second inward pushing grooves 232 correspond one-to-one, and the number and arrangement of the first inward pushing grooves 222 and the second inward pushing grooves 232 are consistent with the number and arrangement of the push-pull pins 13. When the first locking tongue 22 and the second locking tongue 23 are in contact with each other, the first inward pushing grooves 222 and the corresponding second inward pushing grooves 232 form a through hole, and the diameter of the through hole is smaller than the diameter of the rear end of the locking pin 12.

[0138] Combine Figure 8 When the lock body assembly 1 is pushed into the lock box 2 along the inward pushing direction, the first lock tongue 22 clamps the locking push pin 12 through the first inward pushing groove 222, and the second lock tongue 23 clamps the locking push pin 12 through the second inward pushing groove 232. When the lock body assembly 1 changes from being pushed into the lock box 2 to being removed from the lock box 2, the locking push pin 12 disengages from the first lock tongue 22 through the first inward pushing groove 222 along the outward pulling direction, and disengages from the second lock tongue 23 through the second inward pushing groove 232.

[0139] Meanwhile, in this embodiment, the first locking tongue 22 has a first inward pushing auxiliary inclined surface 225 at one end of the first inward pushing groove 222 facing the outward pulling direction. The second locking tongue 23 has a second inward pushing auxiliary inclined surface 235 at one end of the second inward pushing groove 232 facing the outward pulling direction.

[0140] In the process of the locking pin 12 moving in the inward pushing direction and driving the first lock tongue 22 and the second lock tongue 23 to move away from each other, the inward pushing guide slope 122 on the locking pin 12 respectively fits with the first inward pushing auxiliary slope 225 on the first lock tongue 22 and the second inward pushing auxiliary slope 235 on the second lock tongue 23 to push the first lock tongue 22 and the second lock tongue 23 away from each other.

[0141] Combine Figure 5 , he 26 and Figure 27 The pull-out locking device further includes a limiting piece 25. The limiting piece 25 is detachably connected to the housing 21, and is located on the side of the first locking tongue 22 facing the second clamping direction and on the side of the second locking tongue 23 facing the first clamping direction.

[0142] When the lock body assembly 1 is pulled out of the lock box 2, the clamping elastic member 24 pushes the first lock tongue 22 and the second lock tongue 23 to contact the limiting piece 25. Figure 13It is understood that when the first and second locking tongues 22, 23 come into contact with the limiting plate 25, the lower surface of the first locking tongue 22 and the upper surface of the second locking tongue 23 are in contact with each other. The setting of the limiting plate can prevent the position of the first and second locking tongues 22, 23 from changing, thereby affecting the insertion of the locking push pin 12 and the push-pull pin 13 through the first and second locking tongues 22, 23.

[0143] It should be noted that, when the lock body assembly 1 is detached from the lock box 2, the relative position of the rear end of the push-pull pin 13 and the rear end of the locking push pin 12 in the inward pushing direction can be that the rear end of the push-pull pin 13 extends out of the rear end of the locking push pin 12, or the rear end of the locking push pin 12 extends out of the rear end of the push-pull pin 13.

[0144] When the rear end of the push-pull pin 13 extends beyond the rear end of the positioning push pin 12, during the process of pushing the lock body assembly 1 into the lock box 2, the push-pull pin 13 first stretches out the first lock tongue 22 and the second lock tongue 23, and then the positioning push pin 12 enters the first inner push groove 222 and the second inner push groove 232 until the rear end of the positioning push pin 12 is engaged with the lock tongue; during the process of the lock body assembly being separated from the lock box 2, the handle 14 is used to compress the reset elastic member 17 to drive the push-pull pin 13 and make the push-pull pin 13 first stretch out the first lock tongue 22 and the second lock tongue 23, and then the positioning push pin 12 enters the first inner push groove 222 and the second inner push groove 232 until it exits.

[0145] When the rear end of the locking push pin 12 extends beyond the rear end of the push-pull pin 13, during the process of pushing the lock body assembly 1 into the lock box 2, the locking push pin 12 first opens the first lock chamber 22 and the second lock tongue 23, and the push-pull pin 13 then enters the first outer pull-out groove 223 and the second outer pull-out groove 233 until the rear end of the locking push pin 12 is engaged with the lock tongue; when the lock body assembly is separated from the lock box 2, the push-pull pin 13 first opens the first lock tongue 22 and the second lock tongue 23, and the locking push pin 12 then enters the first inner push groove 222 and the second inner push groove 232 until it is separated.

[0146] In this embodiment, when the lock body assembly 1 is detached from the lock case 2, the rear end of the push-pull pin 13 extends beyond the rear end of the locking push pin 12. During the process of the lock body assembly 1 moving from detachment to insertion into the lock case 2, the rear end of the push-pull pin 13 contacts the first and second lock tongues 22 and 23 before the locking push pin 12. Subsequently, as the lock body assembly 1 continues to move inward, the push-pull pin 13 does not pass through the first and second lock tongues 22 and 23, but instead compresses the return spring 17. After the locking push pin 12 separates the first and second lock tongues 22 and 23 to a certain extent, the push-pull pin 13, under the action of the return spring 17, passes through the first and second lock tongues 22 and 23 together with the locking push pin 12. The maximum cross-sectional area of ​​the push-pull pin 13 at the rear end of the first and second grooves facing the inward direction is greater than the maximum cross-sectional area of ​​the locking push pin 12 at the rear end of the first and second slots facing the inward direction.

[0147] In this embodiment, combined with Figure 3 and Figure 5 The housing 21 includes a body 211 and a cover 212. The cover 212 is fixed to the housing 21 by screws. The limiting piece 25, the clamping elastic member 24, the first locking tongue 22, and the second locking tongue 23 are all located in the cavity enclosed by the body 211 and the cover 212. Horizontally, slots 2111 are formed on the left and right inner walls of the body 211. The limiting piece 25 is inserted into the lock box 2 through the slots 2111.

[0148] Combine Figure 13 An upper guide post 26 and a lower guide post 27 are also fixedly disposed within the housing 21. The top end of the upper guide post 26 is fixedly connected to the housing 211, while the bottom end of the upper guide post 26 is vertically slidably connected to the first locking tongue 22. The bottom end of the lower guide post 27 is fixedly connected to the cover 212, while the top end of the lower guide post 27 is vertically slidably connected to the second locking tongue 23. The provision of the upper guide post 26 and the lower guide post 27 ensures the stability of the sliding movement of the first and second locking tongues 22 and 23.

[0149] The pull-out locking device provided in this embodiment has a simple structure, is easy to operate, conforms to ergonomics, and can quickly lock and remove the locking bracket.

[0150] Example 2

[0151] This embodiment provides a computer, see Figure 28 and 29 The computer includes a chassis 5 and the drawer lock device of Example 1. The chassis 5 is provided with a drawer compartment 51, with one end of the drawer compartment 51 facing outwardly exposed from the chassis 5. The housing 21 is located within the drawer compartment 51 and is fixedly connected to the chassis 5 via screws. The lock body bracket 11 is slidably connected to the chassis 5 via the drawer compartment 51 in both the inward and outward directions.

[0152] It is understandable that when the drawer module on the computer is fixedly connected to the lock body bracket 11 , the drawer module and the chassis 5 can be quickly locked and disassembled.

[0153] In this embodiment, the computer is a network security machine, and the pull-out modules are ENS (Ethereum Name Service) modules 4 and the number is eight. Figure 4 、 Figure 30 and Figure 31 The pull-out locking device further includes a tray 3, the front end of the tray 3 and the lock body bracket 11 are fixedly connected in an integrally formed manner, but the present invention is not limited thereto. Figure 1 and Figure 32 , each ENS module 4 is fixed to the corresponding tray 3 by screws.

[0154] During the removal of the ENS module 4, simply insert your finger inside the handle 14 and pull it outward about 5 mm until you hear a click, and the ENS module 4 is unlocked. Continue pulling it outward to remove the ENS module 4. During the installation of the ENS module 4, align the ENS module 4 with the module cage and vertically insert it into the chassis 5. Then, press the handle 15 with your finger and push it inward until you hear a click. The ENS module 4 is now installed in place, and the rear end of the ENS module 4 is plugged into the slot 2111 in the chassis 5. The ENS module 4 has been locked by the pull-out locking device.

[0155] Specifically, the locking and unlocking process between the ENS module 4 and the lock box 2 is as follows:

[0156] Combine Figure 1 、 Figure 7 and Figure 8 When the ENS module 4 is pushed into the chassis 5, the locking push pin 12 pushes the first lock tongue 22 and the second lock tongue 23 apart through the inward pushing guide slope 122. Then, the push-pull pin 13 and the locking push pin 12 will pass through the first lock tongue 22 and the second lock tongue 23. After the locking push pin 12 passes through the first lock tongue 22 and the second lock tongue 23, the first lock tongue 22 and the second lock tongue 23 will be reset due to the action of the clamping elastic member 24, thereby locking the locking push pin 12. At the same time, the rear end of the push-pull pin 13 will be reset to the rear side of the first lock tongue 22 and the second lock tongue 23 due to the action of the reset elastic member 17. In this way, the ENS module 4 and the lock box 2 are locked.

[0157] Combine Figure 1 、 Figure 10 and Figure 11When the handle 14 is pulled outward approximately 5 mm, the first and second locking tongues 22 and 23 are pushed apart by the push-pull pin 13, and the locking push pin 12 is unlocked. The locking push pin 12 is then pulled outward further, disengaging the first and second locking tongues 22 and 23. Finally, the ENS module 4 is pulled outward to be smoothly removed from the chassis 5. This unlocks the ENS module 4 from the lock box 2.

[0158] The computer loads the ENS module 4 through a locking and pulling device, which enables quick disassembly and installation of the ENS module 4 and is easy to operate. When replacing or maintaining the ENS module 4, the ENS module 4 can be easily pulled out by pulling it outward in the same direction, achieving tool-free replacement and maintenance of the ENS module 4 and improving the user experience.
