Description

Technical Field

[0001] The utility model relates to the technical field of placing racks, in particular to a head placing rack for preventing needle prick of a dental treatment chair. Background Technique

[0002] The head placing rack for preventing needle prick of a dental treatment chair is an important safety device in the dental diagnosis and treatment environment, aiming to prevent medical staff from being pricked by needles during the treatment process, thereby reducing the risk of cross-infection.

[0003] In the prior art, when placing the head on the placing rack, the correct direction for placing the head is that the head faces 45° to the upper right (as Figure 1 shown). Only when the head is placed at 45° to the upper right, can the placing rack fix the head. If the head faces other positions (as Figure 2 shown), the head cannot be fixed, and the needle of the head will face the medical staff, resulting in the medical staff being easily pricked by the needle of the head when taking the head during the treatment process, increasing the risk of cross-infection and having low safety. Therefore, we need to propose a head placing rack for preventing needle prick of a dental treatment chair. Content of the Utility Model

Specific implementation manner

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 3 - 6 , the present utility model provides a technical solution:

[0025] A head placement rack for preventing needle pricks of a dental treatment chair, including a base 1, a mounting bracket 2 is fixedly installed on the top of the base 1, a plurality of hinge blocks 6 are fixedly connected to the inner top of the mounting bracket 2, and a plurality of clamping seats for fixing the head are arranged on the hinge blocks 6;

[0026] The clamping seat includes an adjustment seat 7, an arc-shaped ring 11 and a clamping mechanism. The arc-shaped ring 11 is fixedly connected to the adjustment seat 7. The adjustment seat 7 is hinged to the hinge block 6. The clamping mechanism is arranged inside the adjustment seat 7 and the arc-shaped ring 11. A tension spring 16 is hung on the side of the base 1. One end of the tension spring 16 is hung on the surface of the arc-shaped ring 11. The adjustment seat 7 and the arc-shaped ring 11 are arranged obliquely. A protective cover 3 for protecting the head is fixedly installed on the top of the mounting bracket 2;

[0027] A clamping groove 18 is arranged on the inner wall of the adjustment seat 7, and a first avoidance groove 17 is opened inside the adjustment seat 7. The first avoidance groove 17 communicates with the clamping groove 18;

[0028] The clamping mechanism includes a pushing spring 12, a moving seat 14 and a clamping wheel 15. The pushing spring 12 is fixedly installed on the inner wall of the adjustment seat 7. The moving seat 14 is fixedly installed at the end of the pushing spring 12. The clamping wheel 15 is movably installed on the side of the moving seat 14. The moving seat 14 is arranged inside the first avoidance groove 17, and the clamping wheel 15 is arranged inside the clamping groove 18;

[0029] In this embodiment, by pushing the spring 12, the moving seat 14 and the clamping wheel 15 cooperate to fix the handle of the machine head, so that the machine head can be fixed in the clamping seat;

[0030] Two groups of positioning rods 13 are symmetrically and fixedly connected to the inner wall of the adjusting seat 7. One ends of the two groups of positioning rods 13 are arranged in the first avoidance groove 17, and the moving seat 14 is slidably mounted on the positioning rods 13;

[0031] It is worth mentioning that the positioning and support of the moving seat 14 can be realized through the positioning rods 13, so that the moving seat 14 can be stably installed in the adjusting seat 7 and the arc-shaped ring 11;

[0032] A second avoidance groove 19 is formed in the adjusting seat 7, and the hinge block 6 is arranged in the second avoidance groove 19;

[0033] A plurality of groups of connecting frames 8 corresponding to the adjusting seat 7 are fixedly connected to the inner wall of the base 1. An installation block 9 is fixedly connected to the connecting frame 8. A buffer sponge 10 is arranged on the side of the installation block 9, and the side of the adjusting seat 7 is attached to the side of the buffer sponge 10;

[0034] It should be noted that through the cooperation of the connecting frame 8, the installation block 9 and the buffer sponge 10, the buffer effect on the adjusting seat 7 is achieved. When the pushing spring 12 drags the adjusting seat 7 through the arc-shaped ring 11, the force of the adjusting seat 7 contacting the installation block 9 is buffered, which can prevent the adjusting seat 7 from colliding with the installation block 9 and causing the machine head to shake;

[0035] A plurality of groups of placement grooves 4 and inclined grooves 5 corresponding to the clamping seat are formed in the mounting frame 2, and the placement grooves 4 are communicated with the inclined grooves 5;

[0036] In this embodiment, when the pushing spring 12 drags the adjusting seat 7 through the arc-shaped ring 11 and the machine head moves into the protective cover 3, the handle of the machine head can move into the inclined groove 5 and contact the inclined groove 5, and the inclined groove 5 can play a role in placing the handle of the machine head;

[0037] In specific use, after the medical staff uses the machine head and places the machine head in the placement rack, first place the handle of the machine head above the arc-shaped ring 11 and then place it in the clamping groove 18 of the arc-shaped ring 11. At this time, in order to facilitate the placement of the machine head, the handle of the machine head will drive the adjusting seat 7 to rotate on the hinge block 6, so that the machine head can be conveniently placed vertically in the arc-shaped ring 11. By pushing the clamping wheel 15 with the cooperation of the pushing spring 12 and the moving seat 14, the clamping wheel 15 can be clamped on the handle of the machine head, so as to fix the machine head;

[0038] After fixing the machine head, the medical staff release the machine head and drag the arc-shaped ring 11 by stretching the spring 16, so that the arc-shaped ring 11, the adjustment seat 7 and the clamping mechanism cooperate, enabling the clamped and fixed machine head to tilt and move into the protective cover 3. The protective cover 3 is used to protect the machine head, preventing the medical staff from being stabbed by the needle of the machine head during the treatment process, reducing the risk of cross-infection, and improving the safety of the medical staff during the treatment process.

[0039] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
