Description

Technical Field

[0001] This utility model relates to a dental comprehensive treatment machine, specifically, to a dental chair triangular base that is easy to weld. Background Technology

[0002] A dental chair is a component of a dental treatment machine. The chair frame includes a triangular base, a lifting support frame, and a cantilever mounting base. The triangular base is placed on the ground and has a mounting base for the lifting support frame. The top of the lifting support frame drives the cantilever mounting base to rise and fall. The triangular base includes a base plate, two triangular upright plates, and a crossbar connecting the two upright plates. The bottoms of the two upright plates are welded to the base plate, and the two ends of the crossbar are welded to the two upright plates. The triangular base requires high precision in welding; therefore, in traditional welding, clamps are needed to fix the positions of the upright plates and crossbar before welding. However, manufacturing clamps not only increases costs but is also cumbersome and affects work efficiency.

[0003] In order to solve the above problems, people have been seeking an ideal technological solution. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a scientifically designed dental chair triangular base that eliminates the need for fixtures to position the parts to be welded, thereby simplifying operations and improving welding efficiency.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a dental chair triangular base that is easy to weld, comprising a base plate, two triangular upright plates and a crossbar. The base plate has two rows of positioning holes pre-drilled at the installation positions of the two triangular upright plates. Each triangular upright plate has a row of positioning protrusions corresponding to one row of positioning holes at its bottom end. Both triangular upright plates are provided with positioning notches for placing the ends of the crossbar.

[0006] Beneficial effects: By inserting the positioning protrusion into the positioning hole, the triangular upright plate can be positioned. Welding can be carried out by hand. The positioning notch can position the crossbar. After welding, the two triangular upright plates and the crossbar are connected as one, improving the strength of the triangular base.

[0007] Based on the above, each end of the crossbar is provided with a positioning slot corresponding to the two positioning notches, and the positioning slot is engaged with the positioning notch.

[0008] Beneficial effect: The crossbar is locked in place by the positioning slot, which can position the upper part of the triangular upright plate and prevent the upper part of the two triangular upright plates from tilting.

[0009] Based on the above, each of the triangular upright plates includes an integrally formed front reinforcing part, a triangular body, and a rear reinforcing part. The rear end of the front reinforcing part is connected to the front root of the triangular body, and the front end of the rear reinforcing part is connected to the rear root of the triangular body.

[0010] Beneficial effects: The front reinforcement and the rear reinforcement significantly improve the support strength of the triangular upright plate.

[0011] Based on the above, the height of the front reinforcing part gradually decreases from the rear end to the front end, and the height of the rear reinforcing part gradually decreases from the front end to the rear end.

[0012] Based on the above, each column of positioning bumps consists of three positioning bumps: a front end, a middle end, and a rear end. Attached Figure Description

[0018] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0019] like Figure 1-4 As shown, a dental chair triangular base that is easy to weld includes a base plate 1, two triangular upright plates 2 and a crossbar 3. The base plate 1 has two rows of positioning holes 4 pre-drilled at the installation positions of the two triangular upright plates 2. Each triangular upright plate 2 has a row of positioning protrusions 5 corresponding to a row of positioning holes 4 at its bottom end. In this embodiment, a row of positioning protrusions 5 consists of three positioning protrusions 5: a front end, a middle end and a rear end.

[0020] Both of the triangular upright plates 2 are provided with positioning notches 6 on their rear sides for placing the ends of the crossbar 3 (the positioning notches 6 can be located at the top or in the middle). The two ends of the crossbar 3 are respectively provided with positioning slots 7 corresponding to the two positioning notches 6. The positioning slots 7 are engaged in the positioning notches 6 to position the left and right positions of the crossbar 3.

[0021] During assembly, the positioning protrusion 5 at the bottom of the triangular upright plate 2 is inserted into the positioning hole 4 by hand to complete the positioning of the triangular upright plate 2. At this time, welding can be carried out by hand. After the two triangular upright plates 2 are welded, the positioning slots 7 at both ends of the crossbar 3 are locked onto the positioning notch 6 to position the upper part of the triangular upright plate 2 and prevent the upper part of the two triangular upright plates 2 from being tilted. Then, the contact part between the crossbar 3 and the triangular upright plate 2 is welded, and finally the two triangular upright plates 2 and the crossbar 3 are connected as one.

[0022] To improve the support strength of the triangular base, each of the triangular upright plates 2 includes an integrally formed front reinforcing part 21, a triangular body 22, and a rear reinforcing part 23. The rear end of the front reinforcing part 21 is connected to the front root of the triangular body 22, and the front end of the rear reinforcing part 23 is connected to the rear root of the triangular body 22. The height of the front reinforcing part 21 gradually decreases from the rear end to the front end, and the height of the rear reinforcing part 23 gradually decreases from the front end to the rear end.

[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.
