Description

Technical Field

[0001] This utility model relates to the field of dental treatment machine technology, and in particular to an upper hanging rod. Background Technology

[0002] The hanging instrument tray is used to hold instruments such as operating phones. Doctors need to pull the lever to extend the operating phone and other medical instruments to the vicinity of the patient's mouth so that doctors can perform surgery.

[0003] The existing hanging instrument tray uses a straight rod structure for the pull rod. The straight rod structure is a rigid rod that can only move in one direction. However, in actual use, doctors often need to change the angle, and the freedom of movement of the pull rod is restricted, resulting in a limited range of use for dental handpieces and inflexible use. Utility Model Content

[0004] In order to address the technical deficiencies mentioned in the background section, the purpose of this utility model is to provide an upper hanging rod.

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

[0006] A hanging rod, comprising:

[0007] A pull rod holder, one end of which is fixed to the upper hanging instrument tray;

[0008] A folding assembly, the folding assembly including an elastic element, one end of which is rotatably connected to the other end of the pull rod seat; and...

[0009] A swing arm, one end of which is fixedly connected to the other end of the elastic element, the other end of which is used to support the pipe of the mobile phone; the swing arm is bent based on the elastic element with the other end of the pull rod seat as the support point.

[0010] By adopting the above technical solution, pulling the pipe can drive the swing arm to move. Under the action of external pulling force and elastic element, the swing arm can be folded relative to the pull rod seat to adapt to different working positions of the mobile phone. Moreover, the elastic element, due to the properties of its elastic material, can swing in a small range in the horizontal direction to more accurately adjust the position of the mobile phone. The structure is simple, flexible in use, and has stronger compatibility.

[0011] Furthermore, the folding assembly also includes a pull tab. The pull tab is disposed on the bent side of the elastic element, with one end fixedly connected to the other end of the pull rod seat and the other end fixedly connected to one end of the swing rod. The pull tab can support the elastic element and also ensure that the elastic element can only fold in the bending direction, improving the stability of the structure.

[0012] Furthermore, the elastic element is configured as a spring structure, which is simple in structure, has a greater degree of bending, and improves the usability of the mobile phone.

[0013] Furthermore, one end of the swing arm is provided with a first mounting groove. The folding assembly also includes a first connecting block and a second connecting block. The other ends of the first connecting block, the pull tab, and the elastic element are sequentially screwed into the first mounting groove. The other end of the pull rod seat is provided with a second mounting groove, and one end of the second connecting block, the pull tab, and the elastic element are sequentially screwed into the second mounting groove. Installation and disassembly are convenient, improving assembly efficiency.

[0014] Furthermore, the folding assembly also includes a rubber cover. The rubber cover is disposed between the first connecting block and the second connecting block, and the elastic element and the pull tab are housed within the rubber cover, which helps protect the pull tab and the elastic element, extending their service life. The pull rod seat, the second connecting block, the rubber cover, the first connecting block, and the side of the swing rod facing the bending direction are smoothly connected, facilitating pipe installation and use, and ensuring more even force distribution during bending of the upper hanging rod.

[0015] Furthermore, the upper hanging rod also includes a control valve and a control cable for controlling the opening and locking of the mobile phone. One end of the control valve is connected to one end of a pipe, and the other end of the control valve is connected to one end of the control cable. The pull rod seat has a connecting groove with openings at both ends. The control cable is located within the connecting groove, and the other end of the control cable is in contact with one end of the swing arm. When the elastic element bends, the other end of the control cable separates from the end of the swing arm and protrudes from the connecting groove, putting the mobile phone in an activated state. Bending the folding assembly automatically triggers the opening of the mobile phone, making it more convenient to use and increasing work efficiency.

[0016] Furthermore, the pull rod seat has a limiting groove at one end where the control valve is located. The limiting groove communicates with the connecting groove. The diameter of the limiting groove at the control valve end is smaller than the diameter at the connecting groove end, and the area of ​​the limiting groove at the connecting groove end is smaller than the area of ​​the maximum cross-section of the control valve. This limits the extension stroke of the control valve and prevents the control line from being pushed out of the connecting groove.

[0017] In summary, the beneficial effects of this utility model are as follows:

[0018] This invention allows the swing arm to move by pulling the pipe. Under external pulling force and the action of the elastic element, the swing arm can fold relative to the pull rod base to adapt to different working positions of the mobile phone. Moreover, the elastic element, due to the properties of its elastic material, can swing in a small range in the horizontal direction for more precise adjustment of the mobile phone's position. The structure is simple, flexible in use, and has stronger compatibility. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1-7 The embodiments of this utility model will be described in further detail below.

[0032] A type of hanging rod 1, such as Figure 1 , Figure 2 , Figure 6 As shown, it includes a pull rod base 2, a folding assembly 3, and a swing arm 4. One end of the pull rod base 2 is fixed to the upper instrument tray 7. The folding assembly 3 includes an elastic element 31, one end of which is rotatably connected to the other end of the pull rod base 2. One end of the swing arm 4 is fixedly connected to the other end of the elastic element 31, and the other end of the swing arm 4 is used to support the tube of the mobile phone. The swing arm 4 is bent based on the elastic element 31 with the other end of the pull rod base 2 as the support point.

[0033] Pulling the pipe can drive the swing arm 4 to move. Under the action of external pulling force and elastic element 31, the swing arm 4 can be folded relative to the pull rod seat 2 to adapt to different working positions of the mobile phone. Moreover, due to the elastic material properties, the elastic element 31 can swing in a small range in the horizontal direction to more accurately adjust the position of the mobile phone. The structure is simple, flexible in use, and more compatible.

[0034] In some embodiments, please refer to Figure 2 , Figure 3 , Figure 4To improve the support strength of the elastic element 31 in its unused state and ensure its quality, the folding assembly 3 also includes a pull tab 32. The pull tab 32 is located on the bent side of the elastic element 31, with one end fixedly connected to the other end of the pull rod seat 2 and the other end fixedly connected to one end of the swing rod 4. The pull tab 32 provides support for the elastic element 31 and also ensures that the elastic element 31 can only fold in the bending direction, thus improving structural stability.

[0035] When the upper hanging rod 1 is not in use, the swing rod 4 drives the elastic element 31 to experience a force opposite to the bending direction under its own weight. The pull tab 32 cannot bend in the opposite direction due to the resistance of the elastic element 31. Therefore, the pull tab 32 provides a rigid supporting force to the elastic element 31 and the swing rod 4, effectively preventing deformation of the elastic element 31 even when it is not in use, thus extending its service life. When in use, the elastic element 31 and the pull tab 32 can bend synchronously in the bending direction.

[0036] Specifically, the elastic element 31 can be set as a spring structure, which is simple in structure, has a greater degree of bending, and improves the usability of the mobile phone. The spring has a stronger deformation capacity, is easier to operate, requires less force, and has a strong restoring force, making it easier to drive the swing arm 4 and the pull plate 32 to automatically reset.

[0037] In some embodiments, please refer to Figure 3 , Figure 4 One end of the swing arm 4 is provided with a first mounting groove 41. The folding assembly 3 also includes a first connecting block 33 and a second connecting block 34. The other ends of the first connecting block 33, the pull tab 32, and the elastic element 31 are sequentially screwed into the first mounting groove 41. The other end of the pull rod seat 2 is provided with a second mounting groove 23, and one end of the second connecting block 34, the pull tab 32, and the elastic element 31 are sequentially screwed into the second mounting groove 23. Installation and disassembly are convenient, improving assembly efficiency. Specifically, the opening sides of both the first mounting groove 41 and the second mounting groove 23 are oriented towards the bending direction.

[0038] In some embodiments, please refer to Figure 3 , Figure 4 The folding assembly 3 also includes a rubber cover 35. The rubber cover 35 is positioned between the first connecting block 33 and the second connecting block 34. The elastic element 31 and the pull tab 32 are housed within the rubber cover 35, which helps protect the pull tab 32 and the elastic element 31, extending their service life. The pull rod seat 2, the second connecting block 34, the rubber cover 35, the first connecting block 33, and the swing rod 4 are smoothly connected on the side facing the bending direction, facilitating pipe installation and use, and ensuring more even force distribution during bending of the upper hanging rod 1.

[0039] Specifically, the rubber cover 35 cooperates with the groove walls of the first mounting groove 41 and the second mounting groove 23 to wrap around the pull tab 32 and the elastic member 31. The rubber cover 35 is located on the bent side of the elastic member 31. In use, the rubber cover 35, the pull tab 32, and the elastic member 31 are bent together.

[0040] In some embodiments, please refer to Figure 3 , Figure 5 , Figure 7 The upper hanging rod 1 also includes a control valve 5 and a control cable 6 for controlling the opening and locking of the mobile phone. One end of the control valve 5 is connected to one end of the pipe, and the other end of the control valve 5 is connected to one end of the control cable 6. The pull rod seat 2 has a connecting groove 21 with openings at both ends. The control cable 6 is located in the connecting groove 21, and the other end of the control cable 6 is in contact with one end of the swing rod 4. When the elastic element 31 bends, the other end of the control cable 6 separates from the end of the swing rod 4 and protrudes from the connecting groove 21, and the mobile phone is in the activated state. Bending the folding assembly 3 can automatically trigger the opening of the mobile phone, making it more convenient to use and more efficient.

[0041] In some embodiments, please refer to Figure 5 The lever seat 2, with the control valve 5 at one end, is also provided with a limiting groove 22. The limiting groove 22 is connected to the connecting groove 21. The diameter of the limiting groove 22 at the end of the control valve 5 is smaller than the diameter of the limiting groove 22 at the end of the connecting groove 21, and the area of ​​the limiting groove 22 at the end of the connecting groove 21 is smaller than the area of ​​the maximum cross-section of the control valve 5. This is used to limit the extension stroke of the control valve 5 and prevent the control line 6 from being pushed out of the connecting groove 21.

[0042] Specifically, when the swing arm 4 bends, the end of the swing arm 4 separates from the other end of the pull rod seat 2. The control valve 5 pushes the control cable 6 towards the swing arm 4, triggering the phone to open, improving work efficiency and ease of use. The limiting groove 22 limits the distance the control valve 5 pushes the control cable 6 out. The limiting groove 22 can be set as a stepped structure. After the phone is used, the pipe is released, and the swing arm 4 rebounds to its initial position under the restoring deformation force of the elastic element 31. The end of the swing arm 4 contacts the other end of the pull rod seat 2, and the end of the swing arm 4 pushes the protruding control cable 6 into the connecting groove 21. The control cable 6 pushes the control valve 5 back to its initial position, simultaneously triggering the phone to close. This allows for uninterrupted operation, high work efficiency, and simple and convenient operation.

[0043] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
