[0031] like Figures 1 to 8 As shown, according to a first aspect of the present invention, the present invention provides an instrument tray for a dental treatment chair, comprising an instrument tray body 1, a plurality of instrument cables 4 mounted on the bottom of the instrument tray body 1, the ends of the instrument cables 4 being connected to medical devices 3, and a cable storage mechanism 2 provided at the bottom of the instrument tray body 1, the cable storage mechanism 2 comprising a plurality of cable storage components 20, each cable storage component 20 being configured in a one-to-one correspondence with an instrument cable 4, and the cable storage component 20 comprising a base 2. 1. The cable guide 26 and the guide bar 22 are detachably installed on the bottom of the instrument tray 1. A partition 210 is provided in the middle of the base 21, which divides the base 21 into an instrument chamber and a storage chamber. The storage chamber is used to store the instrument cable 4. Multiple guide bars 22 are installed on the partition 210. A slide 23 is provided in the guide bar 22. The slide 23 is slidably connected to the guide bar 22. The cable guide 26 is installed on the slide 23 through a bearing, and the cable guide 26 is located in the storage chamber.

[0032] Through the above design scheme, the slide 23 can slide in the guide row 22, and the length of the instrument thread 4 in the storage chamber is controlled by the cable guide wheel 26. When the cable guide wheel 26 slides backward, the instrument thread 4 is brought back into the storage chamber, reducing the length of the exposed instrument thread 4. In this embodiment, two sets of guide rows 22 are provided on each set of partitions 210. Each set of guide rows 22 is linked to a set of movable cable guide wheels 26, and a set of fixed cable guide wheels 26 is also installed on the partition 210. The two sets of movable cable guide wheels 26 and the set of fixed cable guide wheels 26, together with the instrument thread 4, form a movable pulley structure, which extends the length of the instrument thread 4 entering the storage chamber as much as possible, allowing a smaller space to accommodate as many instrument threads 4 as possible.

[0033] In this embodiment, a light rod 24 is installed on the guide row 22, and a return elastic member 25 is sleeved on the light rod 24. One end of the return elastic member 25 abuts against the slide block 23, and the other end of the return elastic member 25 abuts against the guide row 22.

[0034] With the above design, the slide 23 can always be at the rear end of the guide row 22 by means of the elasticity of the return elastic element 25, and this position is set as the initial position of the slide 23. As the instrument line 4 is pulled out, the slide 23 gradually moves away from the initial position, and at the same time the return elastic element 25 is compressed. After the work is completed, the slide 23 is pushed back to the initial position by the action of the return elastic element 25, and the instrument line 4 is pulled back into the storage chamber.

[0035] In this embodiment, an unlocking assembly 5 is provided in the instrument room. The unlocking assembly 5 includes an unlocking plate 51 and a sliding drive component 50. The sliding drive component 50 is fixedly installed on the partition 210 and is used to drive the unlocking plate 51 to slide on the partition 210. A locking tooth 220 is provided on the guide row 22, and an unlocking groove 221 is provided at the locking tooth 220. The unlocking plate 51 is slidably connected to the unlocking groove 221. A locking tongue 230 is provided on the slide block 23 and is used to abut against the locking tooth 220.

[0036] With the above design, when medical staff need to use dental instruments, the slide 23 moves away from the initial position as the instrument line 4 is pulled away. At the same time, the latch 230 on the slide 23 will abut against the clasp 220 to prevent the instrument line 4 from automatically retracting and affecting the operation when the medical staff releases their grip. When it is necessary to unlock and retract the instrument line 4, the sliding drive 50 is activated, and the unlocking plate 51 is raised so that it is slightly higher than the clasp 220. The raised unlocking plate 51 will push the latch 230 away from the clasp 220. After the restriction of the clasp 220 is removed, the slide 23 will be automatically pushed back to the initial position under the action of the return elastic member 25. The instrument line 4 that has been pulled out of the storage chamber will be brought back to the storage chamber, completing the automatic storage work.

[0037] In this embodiment, sliding rods 52 are fixedly connected to both sides of the unlocking plate 51, and a slider 53 is fixedly installed on the partition plate 210. The sliding rods 52 and the slider 53 are slidably connected. A reset elastic member 54 is sleeved on the sliding rod 52. One end of the reset elastic member 54 abuts against the slider 53, and the other end of the reset elastic member 54 abuts against the unlocking plate 51.

[0038] Through the above design scheme, the sliding rod 52 and the slider 53 cooperate with each other to make the sliding of the unlocking plate 51 smoother. In this embodiment, each of the two sets of guide rails 22 is provided with an unlocking plate 51. The two unlocking plates 51 are connected by the sliding rod 52. The sliding drive member 50 can push the two unlocking plates 51 to slide synchronously at the same time. The reset elastic member 54 on the sliding rod 52 can make the unlocking plate 51 automatically reset. When the sliding drive member 50 retracts, the unlocking plate 51 automatically descends under the action of the reset elastic member 54, so that the latch 230 can re-lock the latch tooth 220.

[0039] In this embodiment, a sliding groove is provided on the base 21, one end of the unlocking plate 51 passes through the sliding groove, and a trigger 55 is installed on the end of the unlocking plate 51 that passes through the sliding groove.

[0040] With the above design, the trigger 55 on the outside of the base 21 allows medical staff to manually lift the unlocking plate 51 and unlock it manually, preventing the instrument cable 4 from being unable to retract into the storage chamber due to malfunction of the sliding drive component 50 or sudden power failure.

[0041] In this embodiment, an arc-shaped plate 211 and a protective gasket 40 are provided in the storage chamber. The arc-shaped plate 211 is located in the storage chamber near the connection between the instrument line 4 and the instrument tray body 1, and the protective gasket 40 is located at the bottom of the storage chamber.

[0042] With the above design, the arc plate 211 in the storage chamber is used to guide the bending of the instrument line 4, and the protective gasket 40 can scrape off the dirt on the surface of the instrument line 4 to prevent the dirt from returning to the storage chamber with the instrument line 4. At the same time, the protective gasket 40 can also keep the instrument line 4 in the storage chamber in a relatively taut state to prevent the instrument line 4 from moving back and forth from getting out of the control of the cable tray 26.

[0043] In this embodiment, a hanging rack 10 is provided at the bottom of the instrument tray body 1, a shelf 11 and a main control unit 13 are provided on the top of the instrument tray body 1, and a handle 12 is provided on the side of the instrument tray body 1.

[0044] Since the hanging rack 10, the shelf 11 and the handle 12 are all existing technologies and not the improvement points of this utility model, they are not described in detail in this embodiment.

[0045] In this embodiment, the hanger 10 is equipped with a trigger switch. When medical staff put the medical device 3 back into the hanger 10, the trigger switch sends a signal to the sliding drive 50. The sliding drive 50 controls the unlocking plate 51 to rise, the latch 230 to disengage, the slide 23 to spring back, and the instrument cable 4 to automatically retract, thus automatically completing the storage work.

[0046] According to the second aspect of this utility model, as Figure 9 As shown, a dental treatment chair includes a dental treatment chair body and the aforementioned instrument tray for the dental treatment chair, the instrument tray for the dental treatment chair being mounted on the dental treatment chair body via a support arm.

[0047] With the above design, when dental treatment is required, the medical staff pulls the medical device 3 to pull out the instrument line 4. Under the action of the clasp 230 and the clasp 220, the sliding seat 23 can only move forward and cannot move backward, avoiding the instrument line 4 retracting during the work process and affecting the work. When the medical device 3 is put back on the hanger 10 after the treatment is completed, the trigger switch on the hanger 10 is triggered, the sliding drive 50 is started, the unlocking plate 51 is raised to push the clasp 230 away from the clasp 220. After the restriction is removed, the return elastic element 25 pushes the sliding seat 23 back to the initial position, and the instrument line 4 is carried back to the storage chamber by the cable guide wheel 26, completing the automatic storage work.

[0048] The instrument tray for a dental chair provided by this utility model, compared with the prior art, allows the return elastic element 25 to push the cable guide wheel 26 to pull the instrument cable 4 back into the storage chamber for safekeeping. This reduces the length of the exposed instrument cable 4, prevents the suspended instrument cable 4 from tripping over passing medical staff, and also protects the instrument cable 4 from contamination, extending its service life. The dental chair of this utility model also has the above-mentioned beneficial effects.

[0049] Where there is no conflict, the above embodiments and features can be combined with each other.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
