DETAILED DESCRIPTION
[0022] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the embodiments described in the embodiments of the utility model are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] According to the following Figure 1-6 The invention describes a keyboard key pull detection hook structure provided by an embodiment of the utility model.
[0024] See also Figure 1 The utility model discloses a keyboard key pull-out detection hook structure, including a pull arm 100 and a hook body 200. The hook body 200 is rotatably installed at the lower end of the pull arm 100, and the hook body 200 has a pull-out end 220 that can contact the keyboard key, and the end of the hook body 200 away from the pull-out end 220 should be assembled with the pull arm 100. When the pull-out end 220 is located below the key cap, the pull arm 100 is lifted upward to enable the pull-out end 220 to apply an upward pulling force to the key cap.
[0025] In order to avoid needle breakage, an adjusting member 800 is further provided. The adjusting member 800 is provided between the hook body 200 and the pulling arm 100. The adjusting member 800 is used to limit the hook body 200 from rotating in the force direction 1 when pulling out, and the adjusting member 800 can rotate in the opposite direction of the force direction 1, so that the hook body 200 can rotate and detach from the keyboard when colliding with a keyboard key, that is, when the hook body 200 is limited to move downward, the pulling end 220 reaches under the keyboard key and then lifts up, and the pulling end 220 applies an upward pulling force to the keyboard key (at this time, the entire pulling end 220 will not rotate), and once the pulling end 220 is pressed on the upper surface of the keyboard key, the hook body 200 can rotate toward the side away from the keyboard key, thereby causing the pulling end 220 to detach from the keyboard key.
[0026] Therefore, the keyboard key pull detection hook structure provided in the embodiment of the utility model can provide a stable pull-out force for the keyboard key, and can also rotate and detach from the keyboard key when the hook body 200 is pressed onto the upper surface of the keyboard key, thereby avoiding the situation of needle breakage.
[0027] Combination Figure 3 and Figure 4 As shown, the aforementioned adjusting member 800 includes a bearing seat 810, the bearing seat 810 is fixedly connected to the end of the upper surface of the hook body 200 away from the pulling end 220, and a pin shaft 830 is fixedly arranged on the bearing seat 810, and a protruding seat 820 is fixedly arranged at the lower end of the pulling arm 100, the pin shaft 830 is located in the protruding seat 820, and a torsion spring 840 is arranged between the pin shaft 830 and the protruding seat 820, so that the relative rotation of the hook body 200 and the pulling arm 100 can be realized through the connection between the bearing seat 810 and the protruding seat 820, and in order to avoid the hook body 200 from rotating during the pulling stage of the pulling arm 100 00 produces rotation, and a limit block 850 is also provided. The limit block 850 is fixedly arranged on the side of the lower end of the pulling arm 100 away from the pulling end 220. When the torsion spring 840 is in the natural state, the hook body 200 is in a horizontal state, and the lower end of the limit block 850 is against the upper surface of the hook body 200 to limit the hook body 200 from rotating in the force direction when pulling. However, the limit block 850 cannot limit the reverse rotation of the hook body 200 in the first direction, so that when the hook body 200 is pressed on the upper surface of the keyboard key, the hook body 200 can rotate to a position away from the keyboard key to avoid needle breakage.
[0028] Furthermore, in order to prevent the hook body 200 from being unable to detach from the keyboard key after rotating, the keyboard key pull detection hook structure here also includes an inclined arm 110, which is integrally arranged at the upper end of the pull arm 100, and the inclined arm 110 is inclined upward in the direction of the keyboard key; a mounting seat 300, the mounting seat 300 is located at the upper end of the inclined arm 110, and a slide groove 310 is opened in the mounting seat 300, and a slider 120 adapted to the slide groove 310 is provided at the upper end of the inclined arm 110, and the slide groove 310 is provided. 0 is perpendicular to the inclined arm 110, so that when the hook body 200 is pressed against the upper surface of the keyboard key, the hook body 200 rotates first, and as the hook body 200 continues to descend, the keyboard key exerts a leftward thrust on the hook body 200, so that the hook body 200 exerts a thrust on the pulling arm 100, and this thrust can be transmitted to the position of the slider 120 through the inclined arm 110, so that the slider 120 can slide leftward in the slide groove 310, so that the hook body 200 can detach from the hook body 200 to the left.
[0029] A spring 600 is also provided here, one end of which is fixedly connected to the slider 120, and the other end of the spring 600 is fixedly connected to the upper end of the slide groove 310, so as to return the slider 120. When the slider 120 moves to the left, the spring 600 can be in a compressed state until the hook body 200 drops to the bottom, and the hook body 200 is located below the keyboard key. At this time, due to the action of the torsion spring 840, the hook body 200 returns to a horizontal state.
[0030] Combination Figure 4 and Figure 5 As shown, a guide rod 700 is fixed in the slide groove 310 , and the slider 120 slides on the guide rod 700 , thereby ensuring the sliding stability of the slider 120 .
[0031] Preferably, the lower surface of the hook body 200 is provided with an inclined surface 210, and the end of the inclined surface 210 close to the keyboard key is the high end, and the end of the inclined surface 210 away from the keyboard key is the low end, so that the hook body 200 can rotate to Figure 6 In the state (c), the contact area between the hook body 200 and the keyboard key is small, and the wear is small.
[0032] like Figure 1 , Figure 4 and Figure 5 As shown, an integrated hanging seat 400 is provided above the mounting seat 300 , and a mounting hole 410 is provided on the upper surface of the hanging seat 400 , so as to facilitate the assembly of the device on a power structure providing pulling force.
[0033] The working principle and use process of the utility model: in normal use, the hook body 200 can directly reach the lower end of the keyboard key. When lifting, the pulling end 220 can provide an upward pulling force to the keyboard key, and the limit block 850 prevents the hook body 200 from rotating under force.
[0034] There is another case:
[0035] When the hook body 200 descends, it directly presses on the upper surface of the keyboard key, forming a Figure 6 The state shown in (a);
[0036] The arm 100 continues to descend, and the hook body 200 rotates counterclockwise along the pin 830, so that a certain angle is formed between the hook body 200 and the keyboard key, forming Figure 6 The state shown in (b);
[0037] The arm 100 continues to descend, and the keyboard key exerts a leftward thrust on the hook body 200, so that the slider 120 at the upper end of the arm 100 can slide leftward in the slide groove 310, causing the hook body 200 to move leftward, forming Figure 6 The state shown in (c);
[0038] The pull arm 100 continues to descend until the upper end of the hook body 200 reaches the lower end of the keyboard key, forming a Figure 6 The state shown in (d);
[0039] The arm 100 continues to descend, and the upper end of the hook body 200 is separated from the lower end of the keyboard key. Due to the action of the torsion spring 840, the hook body 200 returns to a horizontal state, and the spring 600 rebounds, pushing the hook body 200 to move rightward through the arm 100, forming a Figure 6 The state shown in (e);
[0040] The pulling arm 100 is lifted upward by the driving structure providing the pulling force, and the pulling end 220 provides an upward pulling force to the keyboard keys. Figure 6 Middle (f).
