[0002] A keyboard is a device used to input commands and data to operate a machine. Cash register keyboards are typically equipped with a stand for support. In traditional machines, the keyboard is fixed inside the stand, making it impossible to rotate the keyboard to accommodate users' preferred posture. Adjustable stands have emerged, but these suffer from drawbacks such as complex structure, high manufacturing cost, and inconvenient operation. Utility Model Content

[0003] To overcome the above-mentioned defects, this application provides a base assembly for a cash register keyboard. The base assembly has a simple and compact structure, is easy to operate, can meet the needs of multi-angle keyboard rotation, and is highly practical.

[0004] The technical solution adopted by this application to solve its technical problem is:

[0005] A base assembly for a cash register keyboard includes a base, an oil reservoir, a rotating mechanism, and an adjusting mechanism. The rotating mechanism is rotatably mounted inside the base. The adjusting mechanism connects the oil reservoir and the rotating mechanism to the base. The rotating mechanism includes a rotating pad and a support tray. A limiting block is provided on the rotating pad, and a limiting groove is formed on the base. The limiting block is rotatably inserted into the limiting groove. The support tray is mounted on the rotating pad and can rotate synchronously with the rotating pad. The oil reservoir is provided between the rotating pad and the base. The support tray is used to fix the keyboard.

[0006] Optionally, the limiting groove is an arc-shaped groove, and the angle of the arc-shaped groove is α, where α ≤ 180°.

[0007] Optionally, the adjustment mechanism includes a rotating shaft and a nut, the rotating shaft passing sequentially through the bearing tray, the rotating pad, the oil reservoir pad and the base, and the rotating shaft is screwed to the nut, and a set of gaskets is provided between the nut and the base.

[0008] Optionally, the gasket assembly includes a first gasket and a second gasket, the first gasket being attached to the base, and the second gasket being located between the first gasket and the nut. The first gasket is a standard gasket, and the second gasket is a butterfly gasket.

[0009] Optionally, a first center hole is provided on the base, a second center hole is provided on the oil storage pad, a third center hole is provided on the rotating pad, and a fourth center hole is provided on the support tray. The rotating shaft passes through the fourth center hole, the third center hole, the second center hole, and the first center hole in sequence.

[0010] Optionally, the rotating pad is fixedly provided with a hook, and the carrying tray is provided with a slot, and the hook is engaged in the slot so that the carrying tray and the rotating pad rotate synchronously.

[0011] Optionally, the support tray is provided with raised reinforcing ribs, and a positioning post is fixedly provided on the support tray. The positioning post is inserted into the positioning hole on the keyboard to fix the keyboard to the support tray.

Detailed Implementation

[0024] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the embodiments of this application. Obviously, the embodiments described in this application are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0025] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such uses of the terms can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0026] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0027] Example: Figure 1-9 As shown, a base assembly for a cash register keyboard includes a base 100, an oil reservoir 200, a rotating mechanism, and an adjusting mechanism 500. The rotating mechanism is rotatably mounted within the base 100. The adjusting mechanism 500 connects the oil reservoir 200 and the rotating mechanism to the base 100. The rotating mechanism includes a rotating pad 300 and a support tray 400. The rotating pad 300 has a limiting block 330, and the base 100 has a limiting groove 130. The limiting block 330 is rotatably inserted into the limiting groove 130. The support tray 400 is mounted on the rotating pad 300 and can rotate synchronously with the rotating pad 300. The oil reservoir 200 is located between the rotating pad 300 and the base 100. The support tray 400 is used to fix the keyboard.

[0028] In use, the keyboard is fixed on the support tray 400, which in turn is fixed on the rotating pad 300. The oil reservoir 200 is coated with wear-resistant lubricant on both sides and is installed between the rotating pad 300 and the base 100. The user can rotate the keyboard horizontally as needed, and the keyboard rotation drives the rotating mechanism to rotate synchronously. In this application, the base 100 supports the rotating mechanism, which in turn supports the keyboard. The horizontal rotation of the keyboard is achieved by utilizing the rotating mechanism's rotation relative to the base 100, thus satisfying the user's desire for personalized usage posture. The adjustment mechanism 500 connects the oil reservoir 200 and the rotating mechanism to the base 100, effectively preventing them from falling off. Furthermore, the tightness of the adjustment mechanism 500 can be adjusted according to the user's preferences to achieve different rotational force requirements. The wear-resistant lubricant on the oil reservoir 200 reduces wear between the base 100 and the rotating pad 300 and facilitates rotational operation. The base assembly of this application has a simple and compact structure, is easy to operate, can meet the needs of multi-angle keyboard rotation, and is highly practical.

[0029] like Figure 4 As shown, the limiting groove 130 is an arc-shaped groove with an angle α, where α ≤ 180°. By designing the limiting groove 130 as an arc-shaped groove, the limiting block 330 slides within the limiting groove 130 when the rotating mechanism rotates. The limiting groove 130 can be designed to any angle between 0 and 180° according to customer requirements, meaning the keyboard can rotate within a 180° range. Of course, the angle of the arc-shaped groove can also be designed to be greater than 180° depending on the actual situation.

[0030] like Figure 1-3 and Figure 9 As shown, the adjustment mechanism 500 includes a rotating shaft 510 and a retaining nut 540. The rotating shaft 510 passes sequentially through the support tray 400, the rotating pad 300, the oil reservoir 200, and the base 100, and is screwed to the retaining nut 540. A set of washers is provided between the retaining nut 540 and the base 100. The rotating mechanism is connected to the base 100 by the screw connection between the rotating shaft 510 and the retaining nut 540. The rotational force of the user rotating the keyboard is adjusted by adjusting the tightness of the retaining nut 540.

[0031] like Figure 3 and Figure 9As shown, the gasket assembly includes a first gasket 520 and a second gasket 530. The first gasket 520 is attached to the base 100, and the second gasket 530 is located between the first gasket 520 and the nut 540. The first gasket 520 is a standard gasket, and the second gasket 530 is a butterfly gasket. Optionally, the rotating shaft 510 is a bolt screwed to the nut 540. Two butterfly gaskets, also called elastic washers, are provided between the first gasket 520 and the nut 540. These butterfly gaskets rely on their own elastic deformation to relax and absorb shock, thereby improving the reliability of the adjusting mechanism 500.

[0032] like Figure 1 and Figure 3-8 As shown, the base 100 has a first center hole 110, the oil reservoir 200 has a second center hole 210, the rotating pad 300 has a third center hole 310, and the support tray 400 has a fourth center hole 410. The rotating shaft 510 passes through the fourth center hole 410, the third center hole 310, the second center hole 210, and the first center hole 110 in sequence. A washer set is fitted on the part of the rotating shaft 510 that extends out of the base 100, and a locking nut 540 is screwed onto this part of the rotating shaft 510. The locking nut 540 is a fastener that achieves anti-loosening function through a special structure or material. Its core principle is to use additional friction or mechanical deformation to prevent the threads from loosening.

[0033] like Figure 6-7 As shown, the rotating pad 300 is fixedly provided with hooks 320, and the supporting tray 400 has slots 430. The hooks 320 are engaged in the slots 430 to make the supporting tray 400 and the rotating pad 300 rotate synchronously. The rotating pad 300 has a disc-shaped structure, and the supporting tray 400 is similarly disc-shaped. Both the hooks 320 and the limiting blocks 330 are bent along the edge of the rotating pad 300, and the bending directions of the hooks 320 and the limiting blocks 330 are opposite. In one possible embodiment, the rotating pad 300 is provided with two hooks 320, which are symmetrically arranged with respect to the axis of the rotating pad 300. Correspondingly, the supporting tray 400 has two slots 430, and the two hooks 320 are engaged in the slots 430 to improve the bonding strength between the rotating pad 300 and the supporting tray 400. Optionally, the hook 320 is bent toward the upper side of the rotating pad 300 and engages with the support tray 400 located above the rotating pad 300, and the limiting block 330 is bent toward the lower side of the rotating pad 300 and engages with the base 100 located below the rotating pad 300.

[0034] like Figure 7As shown, the support tray 400 is provided with raised reinforcing ribs 420, and positioning posts 440 are fixedly provided on the support tray 400. The positioning posts 440 are inserted into the positioning holes on the keyboard to fix the keyboard to the support tray 400. Two positioning posts 440 are provided on the support tray 400 that protrude upwards.

[0035] like Figure 4 and Figure 5 As shown, the oil reservoir 200 is provided with a positioning hook 230, and the base 100 is provided with a positioning groove 140. The positioning hook 230 is inserted into the positioning groove 140 to fix the oil reservoir 200 to the base 100. The oil reservoir 200 is provided with multiple oil storage holes 220, and the base 100 is provided with a retaining edge 120. The positioning hook 230 is used to position the oil reservoir 200 to the base 100 in the circumferential direction, that is, the oil reservoir 200 is fixed during use. The oil storage holes 220 on the oil reservoir 200 increase the oil storage capacity of the oil reservoir 200. Optionally, the oil reservoir 200 has a disc-shaped structure, and the base 100 has a similar disc-shaped structure.

[0036] During installation, place the oil reservoir pad 200 on the base 100, with the positioning hook 230 on the oil reservoir pad 200 engaging with the positioning groove 140 on the base 100. Place the rotating pad 300 on the oil reservoir pad 200, with the limiting block 330 on the rotating pad 300 engaging with the limiting groove 130. Place the support tray 400 on the rotating pad 300, with the hook 320 on the rotating pad 300 engaging with the slot 430 on the support tray 400. Finally, pass the rotating shaft 510 sequentially through the fourth center hole 410, the third center hole 310, the second center hole 210, and the first center hole 110, and fit the washer assembly onto the rotating shaft 510 extending from the base 100. Finally, tighten the nut 540. In use, place the keyboard on the support tray 400, insert the positioning pin 440 into the positioning hole of the keyboard, and rotate the keyboard directly to adjust the keyboard angle.

[0037] It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the scope of protection of this patent application shall be determined by the appended claims.
