Description

Technical Field

[0001] This utility model relates to the field of treatment chair technology, and in particular to a dental treatment chair headrest. Background Technology

[0002] Dentistry is an important branch of medicine that focuses on the prevention, diagnosis, treatment, and functional and aesthetic restoration of oral, dental, and maxillofacial diseases. It covers a wide range of areas, from basic oral health maintenance to complex surgeries, and aims to help patients maintain or restore oral function while improving appearance. During dental treatment, dental chairs are used for oral surgery and examination and treatment of oral diseases. A dental chair is an essential medical device for dentists.

[0003] Existing dental treatment chairs have a headrest fixed on top to support the head. However, when the patient's head is on the headrest, it is easy for it to move during treatment, which can affect the treatment. Therefore, we propose a dental treatment chair headrest to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a dental treatment chair headrest.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A dental treatment chair headrest includes a chair frame and a chair seat. The end of the chair seat is fixedly connected to a mounting mechanism, and both sides of the mounting mechanism are fixedly connected to guide mechanisms. An adjustment mechanism is slidably fitted onto the surface of the guide mechanism, and a limiting mechanism is inserted above the surface of the adjustment mechanism.

[0007] Preferably, the mounting mechanism includes a mounting frame, the end of the chair seat is fixedly connected to the mounting frame, and a headrest is mounted on the surface of the mounting frame by mounting bolts.

[0008] Preferably, the guiding mechanism includes connecting blocks, with connecting blocks fixedly connected to both sides of the supporting headrest, and a guide rod fixedly connected to the outer end of the connecting blocks.

[0009] Preferably, the adjustment mechanism includes an adjustment frame, the surface of the guide rod is fitted with the adjustment frame, and a fixed rod is fixedly connected to the top of the adjustment frame. A push stud is threaded into the outer side of the adjustment frame, and a pressing disc is fixedly connected to the end of the push stud.

[0010] Preferably, the cross-section of the adjustment frame is set as a rectangular frame, and guide sliders are fixedly connected to the upper and lower inner walls of the adjustment frame. The surface of the guide rod is provided with a groove that matches the guide slider.

[0011] Preferably, the limiting mechanism includes an adjusting stud, the adjusting stud is inserted into the internal thread of the fixing rod, and the end of the adjusting stud is connected to one side of the extrusion plate through a bearing, and a buffer pad is glued to the other side of the extrusion plate.

[0012] Preferably, two guide posts are symmetrically fixed on the other side of the extrusion plate, and both guide posts are cylindrical. The fixing rod has a circular hole inside that matches the guide posts.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This device can be easily installed and supported by the mounting bracket and mounting bolts. By rotating the adjusting stud, the compression plate and buffer pad can be moved, so that the two sets of compression plates and buffer pads can be squeezed against the sides of the head, which can effectively limit and fix the patient's head and prevent the head from moving during treatment, thus affecting the treatment. At the same time, when the compression plate moves, the guide post can guide and limit the compression plate.

[0015] 2. This device allows for easy adjustment of the clamping position of the extrusion plate and buffer pad by moving the adjustment frame along the surface of the guide rod, making it suitable for different personnel heads. At the same time, the guide slider can limit and guide the adjustment frame, and when rotated to the push stud, the push stud can move along the adjustment frame, making it easier for the push stud to drive the extrusion plate to press against the surface of the guide rod, thus facilitating the limitation of the adjustment frame.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figure 1-4 A dental treatment chair headrest includes a chair frame 1 and a chair seat 2. The end of the chair seat 2 is fixedly connected to a mounting mechanism 3, and both sides of the mounting mechanism 3 are fixedly connected to guide mechanisms 4. An adjustment mechanism 5 is slidably sleeved on the surface of the guide mechanism 4. The function of the guide adjustment mechanism 5 can be easily adjusted through the guide mechanism 4, and a limiting mechanism 6 is inserted above the surface of the adjustment mechanism 5.

[0027] Furthermore, refer to Figure 2 and Figure 3 It can be seen that the installation mechanism 3 includes a mounting frame 31. The end of the chair seat 2 is fixedly connected to the mounting frame 31, and a support headrest 33 is installed on the surface of the mounting frame 31 by mounting bolts 32. The support headrest 33 is threadedly connected to the mounting frame 31 by the mounting bolts 32, which facilitates the installation of the support headrest 33.

[0028] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the guiding mechanism 4 includes a connecting block 41. Both sides of the headrest 33 are fixedly connected to the connecting block 41, and the outer end of the connecting block 41 is fixedly connected to the guide rod 42. The two connecting blocks 41 can conveniently fix the function of the guide rod 42, and the guide rod 42 can play the role of limiting the guiding and adjusting mechanism 5.

[0029] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the adjustment mechanism 5 includes an adjustment frame 51, the surface of the guide rod 42 is fitted with the adjustment frame 51, and a fixed rod 52 is fixedly connected to the top of the adjustment frame 51. A push stud 54 is threaded into the outer side of the adjustment frame 51, and an extrusion plate 55 is fixedly connected to the end of the push stud 54. By rotating the push stud 54, the extrusion plate 55 can be easily pushed, so that the extrusion plate 55 can come into contact with the surface of the guide rod 42, thereby limiting the adjustment frame 51.

[0030] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the cross-section of the adjustment frame 51 is set as a rectangular frame. By setting the cross-section of the adjustment frame 51 as a rectangular frame, the guide fixing rod 52 can be limited. The upper and lower inner walls of the adjustment frame 51 are fixedly connected with guide sliders 53. The surface of the guide rod 42 is provided with a groove that matches the guide slider 53. Through the groove on the surface of the guide rod 42, the guide slider 53 can slide along the groove when the adjustment frame 51 moves, thus limiting and guiding the adjustment frame 51.

[0031] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the limiting mechanism 6 includes an adjusting stud 61. The adjusting stud 61 is inserted into the internal thread of the fixing rod 52, and the end of the adjusting stud 61 is connected to one side of the extrusion plate 62 through a bearing. The connection between the end of the adjusting stud 61 and the extrusion plate 62 through the bearing allows the extrusion plate 62 to be pushed when the adjusting stud 61 is rotated. A buffer pad 63 is glued to the other side of the extrusion plate 62. By rotating the adjusting stud 61, the extrusion plate 62 and the buffer pad 63 can be pushed.

[0032] Furthermore, refer to Figure 3 and Figure 4 It can be seen that two guide posts 64 are symmetrically fixed on the other side of the extrusion plate 62, and both guide posts 64 are cylindrical. The fixing rod 52 has a round hole that matches the guide post 64. The two guide posts 64 can limit and guide the extrusion plate 62, and the cylindrical shape of the guide posts 64 can reduce wear between them and the fixing rod 52.

[0033] Working principle: When this utility model is in use, when the chair frame 1 is in use, according to the attached... Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 4 By threading the mounting bolt 32 through the mounting bracket 31 and connecting it to the support headrest 33, and simultaneously rotating the push stud 54, the compression plate 55 can be moved away from the surface of the guide rod 42. At this time, the adjusting frame 51 can drive the fixing rod 52 to slide along the surface of the guide rod 42, which facilitates the adjustment of the position of the compression plate 62 and the buffer pad 63. After the compression plate 62 and the buffer pad 63 are properly adjusted, rotating the push stud 54 can cause the compression plate 55 to press against the surface of the guide rod 42, which facilitates the limiting function of the compression plate 62 and the buffer pad 63. At this time, rotating the adjusting stud 61 can push the compression plate 62 and the buffer pad 63 to move, so that the compression plate 62 and the buffer pad 63 can press against both sides of the patient's head, which plays a role in assisting in limiting the patient's head. At the same time, the movement of the guide post 64 can limit and guide the compression plate 62.
