Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of radiation warming tables and relates to a radiation head rotating mechanism applied to a baby radiation warming table. Background Art
[0002] Usually, the radiation head of an infant radiation warming table should have a rotating function. The main function of this rotating mechanism is to be used in some special scenarios. For example, when a mobile DR filming device needs to take X-rays of a patient, the X-ray tube of the filming device usually needs to be placed above the baby's body. At this time, the radiation head will have a certain impact on the X-ray film, and it is necessary to rotate the radiation head to avoid it. For example, when medical staff are performing some surgery on small babies, in order to avoid the radiation head hitting the medical staff's head or the heater inside the radiation head directly radiating at close range to the medical staff and causing burns, it is also necessary to rotate the radiation head to avoid some troubles.
[0003] The radiation head adjustment structure of the traditional infant radiation warming table is as follows Figure 1-Figure 4 As shown, it consists of a head cover, a rotating plate assembly, an upper ring, a rotating seat, a ball handle, a dial, a lower ring, a limit shaft, a limit column, a spring and a column. It can realize the radiation head to rotate 90° left and right in the horizontal direction, but the structure is complex, the assembly is cumbersome and the cost is relatively high. Utility Model Content
[0004] In view of this, the utility model provides a radiation head rotating mechanism applied to an infant radiation warming table in order to solve the problems of the existing radiation head of the infant radiation warming table being complex in adjustment structure, complicated in assembly and high in cost.
[0005] In order to achieve the above object, the utility model provides the following technical solutions:
[0006] A radiation head rotating mechanism used for an infant radiation warming table comprises a base, a rotating plate assembly used in conjunction with the base, and a head cover shell rotatably connected to the base. A sleeve is provided at the bottom of the base, a limit shaft is provided in the base, the limit shaft is sleeved in the sleeve and slidably connected to the sleeve, a spring is sleeved outside the limit shaft, one end of the limit shaft away from the spring passes through the base and is used in conjunction with the rotating plate assembly, the rotating plate assembly comprises a rotating shaft provided in the base, a plurality of limit holes adapted to the limit shaft, and a limit groove slidably matched with the limit shaft, and a dialing hand fixedly connected to the limit shaft is provided on the side of the base away from the rotating shaft.
[0007] Furthermore, the limiting groove and the limiting hole are provided on the same connecting plate, and the plurality of limiting holes are located in the same limiting groove, and the connecting plate is fixedly connected to the head cover. Beneficial effect: The limiting shaft is engaged with different limiting holes to realize the rotation of the radiation head at different angles.
[0008] Furthermore, the limiting groove is a semicircular groove. Beneficial effect: The angle adjustment of the radiation head is limited within a range of 90 degrees.
[0009] Furthermore, two ends of the rotating shaft respectively penetrate the upper and lower ends of the base, and an upper ring and a lower ring are provided at corresponding positions of the penetration.
[0010] Furthermore, a rotating seat is arranged inside the base to rotate in coordination with the rotating shaft.
[0011] Furthermore, one end of the pull handle away from the limiting shaft is fixedly connected with a ball handle. Beneficial effect: the limiting shaft is driven to move downward in the sleeve by the ball handle.
[0012] Furthermore, the lower end of the spring abuts against the bottom of the inner cavity of the base.
[0013] Furthermore, a notch adapted to the dial handle is provided on the base, and the length of the notch is less than the distance from the fixing point of the dial handle and the limit shaft to the top of the spring. Beneficial effect: The dial handle, driven by the ball handle, drives the limit shaft to disengage from the limit hole, compresses the spring, rotates the radiation head, releases the ball handle, and the limit shaft is engaged with the limit hole again under the rebound effect of the spring.
[0014] Furthermore, a column is fixed at the bottom of the base.
[0015] Furthermore, a through hole is provided on the column at a position corresponding to the notch.
[0016] The beneficial effects of the utility model are:
[0017] 1. The radiation head rotating mechanism disclosed by the utility model is applied to the infant radiation warming table. Before the radiation head rotates, the top end of the spring maintains a distance from the fixed position of the dial handle and the limit shaft. When the radiation head needs to be rotated, the limit shaft is driven to move downward in the sleeve by the ball handle and compress the spring. At this time, the limit shaft is disengaged from the limit hole but not from the limit groove, and the radiation head is pushed. The rotating shaft rotates in the upper and lower rings, and the limit shaft slides in the limit groove. The ball handle is released, and the radiation head continues to be rotated. Under the rebound action of the spring, the limit shaft is again stuck in the limit hole to achieve angle adjustment. The limit groove is a semicircular groove, which limits the angle adjustment of the radiation head within the range of 90°. The mechanism is simple and easy to operate.
[0018] 2. Compared with the existing radiation head rotating mechanism of the infant radiation warming table, the radiation head rotating mechanism disclosed by the utility model for use in the infant radiation warming table can replace the limiting column by the limiting groove, which is convenient to assemble and has low cost.

The objectives and other advantages of the present invention can be achieved and obtained through the following description. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] like Figure 1-Figure 4 The radiation head rotating mechanism of the existing infant radiation warming table shown in the figure is composed of a head cover 3, a rotating plate assembly 4, an upper ring 12, a rotating seat 44, a ball handle 7, a dial hand 6, a lower ring 13, a limit shaft 8, a limit column 14, a spring 9 and a column 111. However, the structure of the mechanism is relatively complex and the assembly is relatively cumbersome, so a method as Figure 5-Figure 8 The radiation head rotating mechanism shown is applied to an infant radiation warming table, comprising a base 2, a rotating plate assembly 4 used in conjunction with the base 2, a column 11 fixed to the bottom of the base 2, and a head cover shell 3 rotatably connected to the base 2.
[0034] Reference Figure 7-Figure 8A sleeve 10 located in the column 11 is provided at the bottom of the base 2, and a limit shaft 8 is provided in the base 2. The limit shaft 8 is sleeved in the sleeve 10 and is slidably connected with the sleeve 10. A spring 9 is sleeved outside the limit shaft 8. Before the radiation head is rotated and adjusted, the lower end of the spring 9 is against the bottom of the inner cavity of the base 2. Before the radiation head rotates, the other end of the spring 9 maintains a certain distance from the dial hand 6, and this end passes through the base 2 and is used in conjunction with the rotating plate assembly 4.
[0035] Reference Figure 6 The rotating plate assembly 4 includes a rotating shaft 41 arranged in the base 2, seven limiting holes 43 adapted to the limiting shaft 8, and a limiting groove 42 slidably matched with the limiting shaft 8. The limiting groove 42 is a semicircular groove. The limiting groove 42 of the semicircular groove limits the angle adjustment of the radiation head within a range of 90°. The limiting groove 42 and the limiting hole 43 are arranged on the same connecting plate 5, and the seven limiting holes 43 are located in the same limiting groove 42. The connecting plate 5 is fixedly connected to the head cover 3, and the limiting shaft 8 is clamped with different limiting holes 43 to realize the rotation of the radiation head at different angles. The two ends of the rotating shaft 41 respectively pass through the upper and lower ends of the base 2, and there are upper rings 12 and lower rings 13 at the corresponding positions of the penetration.
[0036] A hand 6 fixedly connected to the limiting shaft 8 is provided on one side of the base 2 away from the rotating shaft 41 , and a ball handle 7 is fixedly connected to one end of the hand 6 away from the limiting shaft 8 , and the ball handle 7 drives the limiting shaft 8 to move downward in the sleeve 10 .
[0037] A rotating seat 44 is disposed in the base 2 and is adapted to rotate with the rotating shaft 41 .
[0038] A notch matched with the dial hand 6 is provided on the base 2, and a through hole is provided on the column 11 at a position corresponding to the notch. The length of the notch is less than the distance from the fixing point of the dial hand 6 and the limit shaft 8 to the top of the spring 9. Driven by the spherical handle 7, the dial hand 6 drives the limit shaft 8 to disengage from the limit hole 43, compress the spring 9, rotate the radiation head, release the spherical handle 7, and the limit shaft 8 is engaged with the limit hole 43 again under the rebound action of the spring 9.
[0039] When the radiation head rotating mechanism applied to the infant radiation warming table is used, before the radiation head rotates, the top end of the spring 9 maintains a distance from the fixing point of the dial handle 6 and the limit shaft 8. When the radiation head needs to be rotated, the ball handle 7 is pushed downward to drive the limit shaft 8 to move downward in the sleeve 10 and compress the spring 9. At this time, the limit shaft 8 disengages from the limit hole 43 but does not disengage from the limit groove 42, and the radiation head is pushed. The rotating shaft 41 rotates in the upper ring 12 and the lower ring 13, and the limit shaft 8 slides in the limit groove 42. The ball handle 7 is released, and the radiation head continues to be rotated. Under the rebound effect of the spring 9, the limit shaft 8 is again stuck in a different limit hole 43 to achieve angle adjustment. The limit groove 42 is a semicircular groove, which limits the angle adjustment of the radiation head within the range of 90°.
[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the utility model.
