Description

Technical Field

[0001] This utility model relates to a dental comprehensive treatment machine, specifically, to a cantilever bidirectional mounting structure and a dental chair. Background Technology

[0002] The dental comprehensive treatment unit is the core equipment for oral diagnosis and treatment. It mainly consists of components such as dental chair, side box, spittoon, instrument tray, and dental lamp. The dental chair frame includes a base, a lifting support frame and a cantilever mounting base. The base is used to place it on the ground, and the base is equipped with a mounting base for mounting the lifting support frame. The top of the lifting support frame drives the cantilever mounting base to rise and fall.

[0003] In existing technologies, most dental chairs have a cantilever mounted on the left side of the cantilever mount. The side case, spittoon, instrument tray, and dental light are then mounted on the cantilever. After installation, the components are positioned as follows: the side case and spittoon are on the left side of the dental chair, the instrument tray is on the right side (mounted on the right end of a horizontal arm), and the dental light is above the dental chair (mounted on a lamp arm). This structure is suitable for most right-handed dentists, but it does not consider the needs of a minority of left-handed dentists, making the procedure very inconvenient for them.

[0004] In order to solve the above problems, people have been seeking an ideal technological solution. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a dental chair with a two-way cantilever mounting structure that allows for the installation of cantilever arms on both sides, facilitating the arrangement of components according to the doctor's operating habits and accommodating the operating needs of a small number of left-handed doctors.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: a cantilever bidirectional mounting structure, including a dental chair frame, the dental chair frame including a cantilever connecting middle seat, the cantilever connecting middle seat being provided with a cantilever left mounting seat and a cantilever right mounting seat for mounting the cantilever, the cantilever left mounting seat and the cantilever right mounting seat being symmetrically arranged with respect to the central axis plane of the cantilever connecting middle seat.

[0007] Based on the above, the left and right mounting bases of the cantilever are two mounting plates extending from both sides of the cantilever connecting seat, and both mounting plates are provided with multiple bolt holes; during installation, the root of the cantilever is connected to the mounting plate and then fixed together with bolts.

[0008] Based on the above, the left and right mounting bases of the cantilever are a horizontal shaft located at the front end of the cantilever connecting seat. The horizontal shaft has two sets of bolt holes that are symmetrically arranged on the left and right. During installation, the root of the cantilever is connected to the horizontal shaft and aligned with one of the bolt holes before being fixed together with bolts.

[0009] Based on the above, the dental chair frame also includes a base and a lifting support frame. The base is provided with a lifting frame mounting seat. The bottom of the lifting support frame is mounted on the lifting frame mounting seat. The cantilever connecting middle seat is mounted on the top of the lifting support frame. The lifting support frame drives the cantilever connecting middle seat to rise and fall.

[0010] This utility model also provides a dental chair, including the cantilever bidirectional mounting structure described above.

[0011] This utility model has substantial features and advancements compared to existing technologies. Specifically, by setting a left and right mounting base for the cantilever, the cantilever can be installed on either the left or right side of the dental chair. The installation positions of each component can be arranged according to the doctor's operating habits. In addition, the applicant previously designed an instrument tray with completely symmetrical left and right operating interfaces. Therefore, regardless of which side the cantilever is installed on, the operation of the instrument tray remains unchanged, which does not affect the use of most right-handed doctors and can also take into account the operating needs of a few left-handed doctors.

[0016] The technical solution of this utility model will be further described in detail below through specific embodiments. Example 1

[0017] like Figure 1 and Figure 2As shown, a cantilever bidirectional mounting structure includes a dental chair frame. The dental chair frame includes a cantilever connecting seat 4, a base 1, and a lifting support frame 3. A lifting frame mounting seat 2 is provided on the base 1. The bottom of the lifting support frame 3 is mounted on the lifting frame mounting seat 2. The cantilever connecting seat 4 is mounted on the top of the lifting support frame 3. The lifting support frame 3 drives the cantilever connecting seat 4 to rise and fall.

[0018] To enable bidirectional installation of the cantilever, the cantilever connecting middle seat 4 is provided with a cantilever left mounting seat 5 and a cantilever right mounting seat 6 for installing the cantilever. The cantilever left mounting seat 5 and the cantilever right mounting seat 6 are symmetrically arranged with respect to the central axis plane of the cantilever connecting middle seat 4.

[0019] In this embodiment, the left cantilever mounting base 5 and the right cantilever mounting base 6 are specifically two mounting plates extending from both sides of the cantilever connecting middle base 4. Both mounting plates are provided with multiple bolt holes 7. During installation, the root of the cantilever is connected to the mounting plate and then fixed together with bolts.

[0020] In practical use, the cantilever can be installed on the left cantilever mounting seat 5 on the left side of the dental chair, with each component installed in the same way as the traditional method, which is convenient for most right-handed doctors to operate; or the cantilever can be installed on the right cantilever mounting seat 6 on the right side of the dental chair, with each component installed in the opposite direction to the traditional method. The applicant has also previously designed an instrument tray with completely symmetrical left and right operating interfaces, so the operation of the instrument tray can remain unchanged no matter which side the cantilever is installed on, thus facilitating the operating needs of a small number of left-handed doctors. Example 2

[0021] like Figure 3 As shown, the left mounting base 5 and the right mounting base 6 of the cantilever are a horizontal shaft set at the front end of the cantilever connecting seat 4. The horizontal shaft has two sets of bolt holes 7 that are symmetrically arranged on the left and right (corresponding to two installation directions respectively). During installation, the root of the cantilever is connected to the horizontal shaft and aligned with one of the sets of bolt holes 7 and then fixed together with bolts. Example 3

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
