[0084] Example 1

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

[0086] It should be noted that the lock body assembly 1 is pushed into the lock box 2 along the inward push 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 push direction, which means that the lock body assembly 1 is partially inserted into the lock box 2.

[0087] Combination Figure 2 and Figure 4The lock body assembly 1 includes: a lock body bracket 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 body bracket 11 facing the inward push direction and is fixedly connected to the lock body bracket 11. The push-pull pin 13 is located on the side of the lock body bracket 11 facing the inward push direction and is movably connected to the lock body bracket 11.

[0088] Combination 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 arranged on the side of the lock body bracket 11 facing the inward pushing 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 with the inward pushing direction.

[0089] The housing 21 may be a box body 211 structure, such as a six-sided box body 211, or a frame structure, such as a square frame; the angle between the first clamping direction and the inward pushing direction may be an acute angle or a right angle. In this embodiment, the housing 21 is a six-sided box body 211; the first clamping direction is perpendicular to the inward pushing direction, and the first clamping direction is an upward direction, the inward pushing direction is a backward direction, and the outward pulling direction is a forward direction. The clamping elastic member 24 is a compression spring.

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

[0091] Combination 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] Combination Fig. 9 , Fig.10 and Fig.11 When the lock body assembly 1 changes from being pushed into the lock box 2 to being detached from 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 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, 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 push 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 to make the first lock tongue 22 and the second lock tongue 23 move away from each other, so as to release the contact between the locking push pin 12 and the first lock tongue 22 and / or the second lock tongue 23 in the outward withdrawal direction, and 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 realizing the separation of the lock body assembly 1 and 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 the locking push pins 12 and the 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 push 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; the first lock tongue 22 and the second lock tongue 23 can have one of them fixedly connected to the shell 21 and the other 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] Further, 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 relatively 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 compatible with 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 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 push-pull pin 13 in contact with 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 locking tongue 22 and the second locking 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 locking tongue 22 and the upper surface of the second locking tongue 23 are both flush with the horizontal plane, but 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 is respectively abutted against the first locking tongue 22 and the second locking tongue 23, and the other end of the clamping elastic member 24 is abutted against the shell 21.

[0099] Specific, combined Fig.12 and 13, an upper positioning groove 221 is provided on the upper surface of the first locking tongue 22, and a lower positioning groove 231 is provided on the lower surface of the second locking tongue 23. The upper positioning groove 221 and the lower positioning groove 231 correspond to the clamping elastic member 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 locking 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 locking tongue 22, and the top ends of the two clamping elastic members 24 abut against the housing 21 respectively; the other two clamping elastic members 24 are located below the second locking 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 locking tongue 23, and the bottom ends of the two clamping elastic members 24 abut against the housing 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 with Figure 6 , Figure 7 and Figure 8 When the lock body assembly 1 changes from being disengaged from the lock box 2 to being pushed into the lock box 2, the locking push pin 12 moves in the inward pushing direction, the locking push pin 12 pushes the first lock tongue 22 and the second lock tongue 23 away from each other, and the push-pull pin 13 moves in the inward pushing direction, and one 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] It can be seen that when the lock body assembly 1 needs to be changed from being separated from the lock box 2 to being pushed into the lock box 2, that is, when the lock body bracket 11 is changed from an unlocked state to a locked state, the push-pull pin 13 is first pushed in the outward pulling direction to make the first lock tongue 22 and the second lock tongue 23 move away 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 a 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] Combination Figure 4 and Fig.14 The lock body assembly 1 further includes: a handle 14 and a handle 15. Fig.15 , Fig.16 and Fig.17 The handle 14 is slidably connected to the lock body bracket 11 along the inner pushing direction and the outer 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 outer 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 Fig.18 The overall shape of the handle 15 is C-shaped, and a first mounting groove 151 is formed on the inner side wall of the handle 15. The handle 14 is located on the inner side of the handle 15 and fits in the first mounting groove 151. The handle 14 is movably connected to the handle 15. The rear end of the handle 15 is respectively inserted into the left and right ends of the lock body bracket 11, and is fixedly connected to the lock body bracket 11 through the side screws; the rear end of the handle 14 passes through the left and right ends of the lock body bracket 11 and is fixedly connected to the push-pull pin 13.

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

[0106] Combination Figure 4 and Fig.19 The lock body 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 the inner locking block 16 is respectively fixedly connected to the handle 14 and the push-pull pin 13. The inner locking block 16 is used to limit one 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 understandable that the locking push pin 12 and the inner locking block 16 can be arranged in an up-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, and the left and right ends of the inner locking block 16 are block-like structures and extend in the outward direction, and are fixedly connected by 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 by screws, and the inner locking block 16 has two through holes 161 adapted to the locking push pin 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 by screws, and the rear end of the locking push pin 12 passes through the inner locking block 16 through the corresponding through holes 161.

[0108] So, combined Figure 6 and Fig. 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 inner lock block 16 can not only prevent the handle 14 from completely separating from the lock body bracket 11, but also provide a larger connection position for the push-pull pin 13, so that the push-pull pin 13 is more easily adapted to the first lock tongue 22 and the second lock tongue 23.

[0109] In this embodiment, combined with Fig.19The shape of the through hole 161 is rectangular, and the cross section of the front end of the locking push pin 12 is a rectangle 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 it is not limited to this. During the movement of the locking push pin 12 relative to the inner lock block 16, the front end of the locking push pin 12 is always located in the through hole 161. By limiting the shape of the locking push pin 12, it is possible to effectively prevent the locking push pin 12 from rotating along its own axis, thereby affecting the working performance of the lock body assembly 1.

[0110] The surface of the inner lock block 16 facing the inward push direction is also fixedly provided with a second limiting convex plate 162. The second limiting convex plate 162 is located on the left and right sides of the corresponding push-pull pin 13. The second limiting convex plate 162 can facilitate the installation of the push-pull pin 13. The surface of the lock body bracket 11 facing the inward push direction is fixedly provided with a third limiting convex plate 111. The third limiting convex plate 111 is located on the left and right sides of the corresponding locking push pin 12. The third limiting convex plate 111 can facilitate the installation of the locking push pin 12.

[0111] Combination Figure 4 , Fig.15 and Fig.18 The lock body assembly 1 further includes a resetting elastic member 17. One end of the resetting elastic member 17 is connected to the handle 14, and the other end of the resetting elastic member 17 is connected to the lock body bracket 11, for applying a force to the handle 14 in the 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] The handle 15 is fixedly provided with two front end protrusions 152 on the bottom wall facing the rear of the first mounting 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; Fig.15 and Fig. 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 enclose 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 locking tongue 22 and the second locking tongue 23 to move away from each other, which can be achieved by setting a slope at a position corresponding to the rear end of the push-pull pin 13 and / or setting a slope at the ends of the first external draw-out groove 223 and the second external draw-out groove 233.

[0117] Combination Fig.16 and Fig.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 an outward-drawing guide inclined surface 132 on its side walls facing the inward-pushing direction of the first groove and the second groove.

[0118] When the lock body assembly 1 is pushed into the lock box 2 along the inward push 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 through the outward withdrawal guide inclined surface 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, so as to release the restriction of the first lock tongue 22 and the second lock tongue 23 on the locking push pin 12.

[0120] It is understandable that the first groove and the second groove can be flat grooves or arc 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. Fig.21 .

[0121] In a further optional embodiment of the present 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 an outward guide inclined surface 132 may be provided on the first groove, but the present embodiment is not limited thereto and does not make any specific limitation thereto.

[0122] In this embodiment, combined with Figure 5 , Figure 7 and Figure 8 The first locking tongue 22 and the second locking tongue 23 are both long strip structures. Figure 5 and Fig. 22 A guide hole structure is provided at one end of the first lock housing 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 can drive the first lock tongue 22 and the second lock housing 23 away from each other through the guide hole structure.

[0123] Specific, combined Fig. 22 and Fig.23 A first outer groove 223 is formed on the surface of the first locking tongue 22 facing the second clamping direction. The first outer groove 223 penetrates the first locking tongue 22 along the outer direction. A second outer groove 233 is formed on the surface of the second locking tongue 23 facing the first clamping direction. The second outer groove 233 penetrates the second locking tongue 23 along the outer direction. The second outer groove 233 overlaps with the first outer 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, 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 locking tongue 22 and the second locking 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] Combination Figure 7 When the lock body assembly 1 is pushed into the lock box 2 along the inward push 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 Fig.23The first locking tongue 22 has a first external auxiliary inclined surface 224 at one end of the first external groove 223 facing the inward pushing direction, and the second locking tongue 23 has a second external auxiliary inclined surface 234 at one end of the second external groove 233 facing the inward pushing direction.

[0127] When the push-pull pin 13 moves in the outward-pulling direction and drives the first lock tongue 22 and the second lock tongue 23 away from each other, the outward-pulling guide slope 132 on the push-pull pin 13 respectively fits with the first outward-pulling auxiliary slope 224 on the first lock tongue 22 and the second outward-pulling auxiliary slope 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 Fig.17 and Fig.24 The surface of the locking push pin 12 facing the first clamping direction is provided with a first clamping groove, and the surface of the locking push pin 12 facing the second clamping direction is provided with a second clamping groove. The end of the locking push pin 12 facing the inward pushing direction is provided with a first inward pushing guide inclined surface 122 and a second inward pushing guide inclined surface 122. The first inward pushing guide inclined surface 122 and the second inward pushing guide inclined surface 122 can be two plane-shaped or arc-shaped inclined surfaces.

[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 around the rear end of the push-pull pin 13.

[0130] In a further optional embodiment of the present embodiment, only the first slot or the second slot 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 be provided with 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 push guide inclined surface 122 facing the first locking tongue 22. When the locking push pin 12 moves in the inward push direction and drives the first locking tongue 22 and the second locking tongue 23 away from each other, the inward push guide inclined surface 122 abuts against the first locking tongue 22 to apply an upward force to the first locking tongue 22.

[0131] In this embodiment, combined with Figure 8 , Fig.17 and Fig.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 locking tongue 22 through the first inward pushing guide slope 122, and abut against the second locking tongue 23 through the second inward pushing guide slope 122; the locking push pin 12 pushes the first locking tongue 22 and the second locking 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 are 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 draw-out locking device is in the state where the lock body assembly 1 is pushed into the lock box 2 along the inward push direction, the first lock tongue 22 is inserted into the first slot, and the second lock tongue 23 is inserted into the second slot. In this way, the locking push pin 12 is engaged with the first lock tongue 22 and the second lock tongue 23 in the outward pull direction, thereby preventing the locking push pin 12 from being separated from the lock box 2 in the outward pull 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 through the first inner push guide inclined surface 122 and the second inner push guide inclined surface 122. In this way, when the locking push pin 12 separates the first lock tongue 22 and the second lock tongue 23, the rear end of the push-pull pin 13 can pass through the first lock tongue 22 and the second lock tongue 23 through the corresponding first outer withdrawal groove 223 and the second outer withdrawal groove 233.

[0134] In this embodiment, combined with Fig.10 , Fig.15 and Fig.23 The push-pull pin 13 has an annular inward push inclined surface 133 at the 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 inner 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] Combination Fig. 22 and Fig.25The surface of the first locking tongue 22 facing the second clamping direction is provided with a first inward pushing groove 222. The first inward pushing groove 222 penetrates the first locking tongue 22 along the inward pushing direction. The surface of the second locking tongue 23 facing the first clamping direction is provided with a second inward pushing groove 232. The second inward pushing groove 232 penetrates the second locking tongue 23 along 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 can be understood that the first inner push groove 222 corresponds to the second inner push groove 232 one by one, and the number and arrangement of the first inner push groove 222 and the second inner push groove 232 are consistent with the number and arrangement of the push-pull pin 13. When the first locking tongue 22 and the second locking tongue 23 are in contact with each other, the first inner push groove 222 and the corresponding second inner push groove 232 form a through hole, and the diameter of the through hole is smaller than the diameter of the rear end of the locking push pin 12.

[0138] Combination 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 separated from the lock box 2, the locking push pin 12 is separated from the first lock tongue 22 through the first inward pushing groove 222 along the outward pulling direction, and is separated 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 push auxiliary inclined surface 225 at one end of the first inward push groove 222 facing the outward withdrawal direction. The second locking tongue 23 has a second inward push auxiliary inclined surface 235 at one end of the second inward push groove 232 facing the outward withdrawal direction.

[0140] In the process that the locking pin 12 moves in the inward pushing direction and drives the first lock tongue 22 and the second lock tongue 23 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] Combination Figure 5 , he 26 and Fig. 27 The pull-out locking device further includes a limiting piece 25. The limiting piece 25 is detachably connected to the housing 21, and the limiting piece 25 is located on the side of the first locking tongue 22 facing the second clamping direction, and is located 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. Fig.13It can be understood that when the first lock tongue 22 and the second lock tongue 23 collide with the limiting piece 25, the lower surface of the first lock tongue 22 and the upper surface of the second lock tongue 23 fit together. By setting the limiting position, the position where the first lock tongue 22 and the second lock tongue 23 fit together can be prevented from changing, thereby affecting the positioning push pin 12 and the push-pull pin 13 from passing through the first lock tongue 22 and the second lock tongue 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 locking push pin 12, during the process of pushing the lock body assembly 1 into the lock box 2, the push-pull pin 13 first opens the first lock tongue 22 and the second lock tongue 23, and then the locking push pin 12 enters the first inner push groove 222 and the second inner push groove 232 until the rear end of the locking 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 open the first lock tongue 22 and the second lock tongue 23, and then the locking push pin 12 enters the first inner push groove 222 and the second inner push groove 232 until it exits.

[0145] With the rear end of the locking push pin 12 extending 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 housing 22 and the second lock tongue 23, and the push-pull pin 13 then enters the first outer withdrawal groove 223 and the second outer withdrawal groove 233 until the rear end of the locking push pin 12 is engaged with the lock tongue; during the process of the lock body assembly detaching 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 detaching.

[0146] In this embodiment, when the lock body assembly 1 is separated from the lock box 2, the rear end of the push-pull pin 13 extends beyond the rear end of the locking push pin 12. In the process of the lock body assembly 1 changing from being separated from the lock box 2 to being pushed into the lock box 2, the rear end of the push-pull pin 13 conflicts with the first lock tongue 22 and the second lock tongue 23 before the locking push pin 12; then the lock body assembly 1 continues to move in the inward pushing direction, at which time the push-pull pin 13 does not pass through the first lock tongue 22 and the second lock tongue 23, but compresses the reset elastic member 17, until the locking push pin 12 separates the first lock tongue 22 and the second lock tongue 23 to a certain extent, and then the push-pull pin 13 passes through the first lock tongue 22 and the second lock tongue 23 together with the locking push pin 12 under the action of the reset elastic member 17. Among them, the maximum cross-sectional area of ​​the push-pull pin 13 at the rear end of the first groove and the second groove facing the inward pushing direction is greater than the maximum cross-sectional area of ​​the locking push pin 12 at the rear end of the first clamping groove and the second clamping groove facing the inward pushing direction.

[0147] In this embodiment, combined with Figure 3 and Figure 5 The housing 21 includes a box body 211 and a box cover 212, and the box cover 212 is fixedly connected 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 surrounded by the box body 211 and the box cover 212. Among them, the left and right inner side walls of the box body 211 are both provided with slots 2111 in the horizontal direction, and the limiting piece 25 is plugged into the lock box 2 through the slots 2111.

[0148] Combination Fig.13 An upper guide column 26 and a lower guide column 27 are also fixedly disposed in the housing 21. The top end of the upper guide column 26 is fixedly connected to the box body 211, and the bottom end of the upper guide column 26 is slidably connected to the first locking tongue 22 along the up-down direction. The bottom end of the lower guide column 27 is fixedly connected to the box cover 212, and the top end of the lower guide column 27 is slidably connected to the second locking tongue 23 along the up-down direction. The upper guide column 26 and the lower guide column 27 can ensure the stability of the sliding of the first locking tongue 22 and the second locking tongue 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 disassemble the locking bracket.

[0150] Example 2

[0151] This embodiment provides a computer, see Fig.28 and 29 The computer comprises: a chassis 5 and the draw-out locking device of Embodiment 1. The chassis 5 is provided with a draw-out bin 51, one end of the draw-out bin 51 facing the outward draw-out direction is exposed to the chassis 5, and the housing 21 is located in the draw-out bin 51 and is fixedly connected to the chassis 5 by screws. The lock body bracket 11 is slidably connected to the chassis 5 along the inward push direction and the outward draw-out direction through the draw-out bin 51.

[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 , Fig.30 and Fig.31 The pull-out locking device further includes a tray 3, and the front end of the tray 3 is fixedly connected to the lock body bracket 11 in an integrally formed manner, but is not limited thereto. Figure 1 and Fig.32 , each ENS module 4 is fixed to the corresponding tray 3 by screws.

[0154] During the disassembly of the ENS module 4, just insert your finger into the inner side of the handle 14, then pull it outwards about 5 mm, and hear a click, then the ENS module 4 is unlocked; continue to pull it outwards to take out 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 outer side of the handle 15 with your finger and push it inwards until you hear a click, then the ENS module 4 is installed in place, the rear end of the ENS module 4 is plugged into the slot 2111 in the chassis 5, and the ENS module 4 has been locked by the pull-out locking device.

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

[0156] Combination Figure 1 , Figure 7 and Figure 8 When the ENS module 4 is pushed into the chassis 5, the positioning push pin 12 pushes the first locking tongue 22 and the second locking tongue 23 apart through the inner push guide inclined surface 122. Then, the push-pull pin 13 and the positioning push pin 12 will pass through the first locking tongue 22 and the second locking tongue 23. After the positioning push pin 12 passes through the first locking tongue 22 and the second locking tongue 23, the first locking tongue 22 and the second locking tongue 23 will be reset due to the action of the clamping elastic member 24 to lock the positioning push pin 12, and at the same time, the rear end of the push-pull pin 13 will be reset to the rear side of the first locking tongue 22 and the second locking tongue 23 by the reset elastic member 17 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] Combination Figure 1 , Fig.10 and Fig.11When the handle 14 is pulled outward by about 5 mm, the first locking tongue 22 and the second locking tongue 23 are stretched apart by the push-pull pin 13, and the positioning push pin 12 is in an unlocked state. After that, the positioning push pin 12 is pulled outward again, and the etching positioning push pin 12 is separated from the first locking tongue 22 and the second locking tongue 23. Finally, the ENS module 4 is pulled outward, and the ENS module 4 can be smoothly pulled out of the chassis 5. In this way, the ENS module 4 and the lock box 2 are unlocked.

[0158] The computer loads the ENS module 4 through a locking and pulling device, which realizes the 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 outwards progressively in the same direction, thereby achieving tool-free replacement and maintenance of the ENS module 4 and improving the user experience.
