Detailed Description
Specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Fig. 1 is an installation schematic view of a mechanism for preventing a CT bed board from loosening according to an embodiment of the present invention.
As shown in figure 1, the utility model provides a mechanism for preventing CT bed board from loosening comprises a fixing frame 1, an inner hexagonal socket head cap screw 2 and a locking frame. Wherein the fixing frame 1 comprises two through holes (not marked in fig. 1) and two clinch nuts (not marked in fig. 1). The fixing frame 1 is fixedly connected with a CT bed plate 5 through two through holes, two press-riveting nuts and a bed plate screw 6; two bed board screws 6 respectively pass through two through holes and are connected with two press riveting nuts.
When the CT scanning bed is installed, two press-riveting nuts are placed into two holes of the fixing frame 1, and the CT bed board 5 and the fixing frame 1 are embedded and fastened through pressure; the bed plate screw 6 is used for fixedly connecting the CT bed plate 5 and the fixing frame 1.
In addition, the locking frame comprises an anti-loosening plate 3 and an outer hexagonal positioning pin 4, and the fixing frame 1 is fixedly connected with the anti-loosening plate 3 through the outer hexagonal positioning pin 4, a bed plate screw 6 and an inner hexagonal socket head cap screw 2.
The outer hexagonal positioning pin 4 is connected with the top of the bed plate screw 6, and a thread is arranged on the outer hexagonal positioning pin, so that the bed plate screw 6 is positioned and locked in the reverse direction by utilizing the thread on the outer hexagonal positioning pin, and the CT bed plate 5 is prevented from loosening.
The outer hexagonal positioning pin 4 is used for being inserted into a head of a bed plate screw 6 of the CT bed plate, the bed plate screw 6 (the bed plate screw 6 adopts an inner hexagonal screw) is positioned and locked in the reverse direction by using threads on the outer hexagonal positioning pin 4, the rotation of the bed plate screw 6 for installing the bed plate is overcome, so that the CT bed plate cannot be loosened or fall off, and the falling of a patient on the CT bed plate and the personal injury are prevented.
The anti-loosening frame is inserted into the top of a bed plate screw 6 of a CT bed plate 5 through an outer hexagonal positioning pin 4 and is fixedly connected to the fixed frame 1 through an inner hexagonal socket head cap screw 2; through the connection of the outer hexagonal positioning pin 4 and the anti-loosening plate 3 with the fixing frame 1 fixed on the CT bed board 5 assembly body, the position of the outer hexagonal positioning pin 4 is firmly fixed and is not easy to loosen or fall off.
Furthermore, in a preferred embodiment of the present invention, the outer hexagonal positioning pin 4 is provided with a thread. When bed board screw 6 will take place to rotate, bed board screw 6 is connected with screwed outer hexagonal locating pin 4, and the screw thread on the screwed outer hexagonal locating pin 4 of locking frame is fixed a position and is reversed locking on the direction to bed board screw 6, has overcome the rotation of bed board screw 6 of CT bed board 5 when using, plays the effect that prevents CT bed board 5 not hard up and break away from to prevent that the patient on the CT bed board 5 from taking place to fall and cause bodily injury.
In the embodiment of fig. 1, it can be seen that when the mechanism for preventing the CT bed board from loosening is installed, two bed board screws and two anti-loosening plates, namely, a bed board screw 6 ', an anti-loosening plate 3 and an anti-loosening plate 3', are adopted on one side of the CT bed board 5. In the installation process, the fixing frame 1 is fixed by bed plate screws 6, and the bed plate screws 6 are locked by tightening torque of 13 N.m; two press-riveting nuts are placed into two through holes of the fixing frame 1 to complete embedding and fastening of the CT bed board and the fixing frame 1 under pressure, so that the connection of the CT bed board 5 and the fixing frame 1 can be very fastened; then the anti-loosening frame is installed, the outer hexagonal positioning pin 4 on the anti-loosening frame is inserted into the bed plate screw 6 for fixing the bed plate, and the nail head of the inner hexagonal socket head cap screw 2 is inserted into the interior of the pressure riveting nut on the fixing frame 1, so that the fixing frame 1 and the anti-loosening frame are fixedly connected. Because the threaded outer hexagonal positioning pin 4 is connected with the bed plate screw 6, when the bed plate screw 6 rotates, the threaded outer hexagonal positioning pin 4 on the anti-loosening frame plays a role in locking the bed plate screw, the rotation of the bed plate screw 6 when the CT bed plate 5 is used is overcome, and therefore the CT bed plate 5 is prevented from loosening and separating.
According to the embodiment, the mechanism for preventing the CT bed board from loosening overcomes the defects of the prior art, and can prevent the screw arranged on the bed board from rotating, so that the effect of preventing the bed board from loosening and separating is achieved; moreover, the mechanism for preventing the CT bed board from loosening has the advantages of detachability, simple, convenient and reliable installation structure, short operation time and capability of meeting the replacement requirement of the CT scanning bed board.
The mechanism for preventing the loosening of the CT bed according to the present invention is described above by way of example with reference to the accompanying drawings. However, it should be understood by those skilled in the art that various modifications can be made to the mechanism for preventing the loosening of the CT bed board provided by the present invention without departing from the scope of the present invention. Therefore, the scope of the present invention should be determined by the content of the appended claims.
