Description

Technical Field

[0001] The utility model relates to the field of key pullers, in particular to a double-head integrated keyboard shaft puller and key puller. Background Art

[0002] A key puller is a common keyboard accessory that can be used to assist users in modifying and repairing keys on the keyboard. In order to facilitate the operator's operation, existing key pullers usually have a shaft puller at the other end to facilitate the operator to remove the key shaft. This type of key puller with different functions at both ends is generally called a double-headed key puller.

[0003] The existing double-headed key puller has a relatively simple structure and is generally cast in one piece. A metal spring is directly provided to assist the operator in pulling out the shaft. After pulling out, the operator is still required to manually remove the key shaft from the middle of the metal spring. The overall device is relatively inconvenient to use. Therefore, a double-headed integrated keyboard shaft puller is proposed to solve the above problem. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0031] Reference Figure 1 - Figure 3 The utility model provides an embodiment of a double-headed integrated keyboard shaft puller and key puller, comprising a front shell 1 for supporting the overall device, a rear shell 2 for closing the rear end opening of the front shell 1 is plugged into the rear end of the front shell 1, after the front shell 1 and the rear shell 2 are plugged in, the two can be fixed by bolts, a key puller assembly 3 for facilitating the operator to pull out the keycap is arranged at the front end of the front shell 1, the key puller assembly 3 comprises a clamping block 31 for supporting a wire sleeve 32, the clamping block 31 is clamped at the front end of the front shell 1, a shaft puller assembly 4 for facilitating the operator to pull out the key shaft is arranged on the inner wall of the front shell 1, the shaft puller assembly 4 comprises a storage block 45 for accommodating a metal spring 47, the storage block 45 is slidably connected to the inner wall of the front shell 1, the storage block 45 can slide up and down on the inner wall of the front shell 1, a metal spring 47 for fixing the key shaft is plugged into the inner wall of the storage block 45, the metal spring 47 has elastic deformation ability, and will be elastically deformed when squeezed.

[0032] Reference Figure 1 - Figure 3 The key pulling assembly 3 also includes a wire sleeve 32 for fixing the keycap, the wire sleeve 32 is rotatably connected to the inner wall of the block 31, and a protrusion 33 for fixing the wire sleeve 32 is provided at the right end of the block 31. The key pulling assembly 3 is provided with multiple groups, and another group of key pulling assemblies 3 is arranged at the rear end of the rear shell 2. By using two groups of wire sleeves 32 to cover the bottom end of the keycap, the operator can easily pull out the keycap, and the front end of the other group of blocks 31 is clamped at the rear end of the rear shell 2.

[0033] Reference Figure 2 , Figure 4 and Figure 5 The pull-shaft assembly 4 also includes a slide bar 41 for driving the slide plate 43 to move. The slide bar 41 is slidably connected to the inner wall of the front housing 1. The top of the slide bar 41 is fixedly connected with a button 42 for facilitating the operator to press the slide bar 41. The bottom end of the slide bar 41 is fixedly connected with a slide plate 43 for driving the extrusion block 410 to move. The bottom end of the slide plate 43 is fixedly connected with an extrusion block 410 for extruding a plastic spring 44. The inner wall of the front housing 1 is fixedly connected with a plastic spring 44 for driving the triangular block 411 to move. The bottom end of the slide plate 43 is fixedly connected with a return spring 49 for pushing the arrow-shaped block 48. The bottom end of the return spring 49 is fixedly connected with an arrow-shaped spring for fixing the storage block 45. The arrow-shaped block 48 and the return spring 49 will always push the arrow-shaped block 48 downward. The arrow-shaped block 48 is fixedly connected to the top of the storage block 45. When the arrow-shaped block 48 moves up and down, the storage block 45 will also move up and down synchronously. The left end of the plastic spring 44 is provided with a triangular block 411 for fixing the arrow-shaped block 48. The triangular block 411 and the arrow-shaped block 48 are adapted to each other. By using the arrow-shaped block 48 to squeeze the inclined surface at the bottom end of the triangular block 411, the triangular block 411 can be forced to move outward. By using the triangular block 411 to be stuck at the bottom end of the arrow-shaped block 48, the arrow-shaped block 48 can be prevented from moving downward. The front end of the storage block 45 is connected with a closing block 46 for closing the front end opening of the storage block 45.

[0034] Working principle: When the keycap needs to be removed, the wire sleeve 32 can be rotated to a vertically upward position. At this time, the protrusion 33 will clamp the wire sleeve 32 so that it will not move at will. Then the wire sleeve 32 can be connected to the rear end of the keycap, and then the front shell 1 can be pulled to drive the wire sleeve 32 to move and remove the keycap.

[0035] When the key shaft needs to be extracted, the metal spring 47 needs to be aligned with the key shaft and moved downward. When the metal spring 47 contacts the keyboard surface, it will be forced to move upward. At the same time, when the metal spring 47 moves upward, it will be squeezed by the inner wall of the front shell 1 and forced to bend inward, so that it can be stuck in the rear end of the key cap. At the same time, when the metal spring 47 moves upward, it will drive the storage block 45 to move upward, and the storage block 45 will drive the arrow-shaped block 48 to move upward. The upward movement of the arrow-shaped block 48 will squeeze the bottom end of the triangular block 411 and force it to move outward. When the arrow-shaped block 48 reaches the top of the triangular block 411, the triangular block 411 will move inward and reset under the support of the plastic spring 44. At this time, the arrow-shaped block 48 will be fixed and unable to move downward. At this time, the reset spring 49 will also be forced to shrink. At the same time, the metal spring 47 will also jam the key shaft. Then, the front shell 1 can be moved upward to pull the key shaft to separate it from the keyboard.

[0036] After the key shaft is removed, the button 42 can be pressed to drive the slide bar 41 to move downward. The downward movement of the slide bar 41 will squeeze the plastic spring 44 to make it move outward. When the plastic spring 44 drives the triangular block 411 to separate from the bottom end of the arrow-shaped block 48, the return spring 49 will quickly recover and push the arrow-shaped block 48 to move downward. The arrow-shaped block 48 will push the storage block 45 and the arrow-shaped block 48 to move downward. After moving downward, the metal spring 47 will no longer be restricted by the front shell 1 and can be unfolded under the action of its own elasticity. In this way, the key shaft will no longer be restricted and will fall freely.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
