Description

Technical Field

[0001] The utility model relates to a film cassette sliding locking device, in particular to a film cassette sliding locking device for an X-ray photography flat bed. Background Art

[0002] Generally, a film cassette sliding locking device is arranged under the bed board of an X-ray photography flat bed. When a film cassette needs to be installed, the film cassette is connected to the bed board through the film cassette sliding locking device to realize the functions of horizontal movement and locking of the film cassette.

[0003] The existing film cassette sliding locking device of an X-ray photography flat bed usually includes two sets of linear guide rails and a set screw handle. Each set of linear guide rails has two sliders that can move along its extending direction. The two sets of linear guide rails are fixedly spaced under the bed board. The set screw handle is arranged outside one set of linear guide rails. By rotating the set screw handle, the set screw handle can pass through a slider on the linear guide rail and abut against the side wall of the linear guide rail, and can also separate the set screw handle from the side wall of the linear guide rail. When installing the film cassette, the film cassette is fixed under the four sliders on the two sets of linear guide rails. At this time, by rotating the set screw handle, the horizontal movement and locking of the film cassette can be realized. When the set screw handle abuts against the side wall of the linear guide rail, the film cassette cannot move along the two sets of linear guide rails with the four sliders and is in a locked state. When the set screw handle is separated from the side wall of the linear guide rail, the film cassette can move along the two sets of linear guide rails with the four sliders to adjust the position.

[0004] Since the locking force is provided by the frictional force between the set screw handle and the contact surface of the linear guide rail, therefore, the existing film cassette sliding locking device of an X-ray photography flat bed has poor locking effect and is easy to loosen, and there is a risk of unlocking under vibration conditions such as handling, disassembly and assembly, so it needs to be frequently checked during maintenance; at the same time, since the rotation position of the handle of the set screw handle is not fixed when the film cassette is locked, the locking state cannot be judged by direct observation, and it is necessary to frequently move the film cassette to determine whether it is locked, which is very inconvenient. Summary of the Invention

[0005] The technical problem to be solved by the utility model is to provide a film cassette sliding locking device for an X-ray photography flat bed with good locking effect, not easy to loosen, and capable of directly observing and judging the locking state, which is convenient to use.

[0006] The technical solution adopted by the present utility model to solve the above technical problems is as follows: A film cassette sliding locking device for an X-ray photography flat bed, which includes two sets of linear guide rails. On each set of linear guide rails, there are respectively two sliders that can move along them. The two sets of linear guide rails are respectively referred to as the first linear guide rail and the second linear guide rail. The first linear guide rail is arranged on the front side under the bed panel of the X-ray photography flat bed and is fixed on the bed panel of the X-ray photography flat bed. The second linear guide rail is arranged on the rear side under the bed panel of the X-ray photography flat bed and is fixed on the bed panel of the X-ray photography flat bed. The film cassette sliding locking device of the X-ray photography flat bed further includes a limit plate and a plunger assembly. The limit plate is arranged on the front side of the first linear guide rail and is fixed on the bed panel of the X-ray photography flat bed. The limit plate is provided with a plurality of through holes vertically. The plurality of through holes are spaced along the moving direction of the slider. The plunger assembly is installed on the film cassette. When the film cassette is installed on the slider, the plunger assembly is located below the limit plate. The plunger assembly can pass through the through hole from bottom to top to lock the film cassette and can also leave the through hole.

[0007] The plunger assembly includes a fixed block and a rotating plunger. The fixed block is installed on the outside of the film cassette. The fixed block is provided with a first threaded hole vertically penetrating. The rotating plunger can pass through and be fixed at the first threaded hole.

[0008] The plunger assembly further includes a fastening screw. The fixed block is provided with a second threaded hole communicating with the first threaded hole. The second threaded hole is arranged horizontally. The fastening screw can pass through the second threaded hole and be fixed.

[0009] Each set of linear guide rails is realized by a hanging rail, and each slider is realized by a hanging wheel assembly.

[0010] Hanging rail limiters are respectively installed at both ends of each set of linear guide rails.

[0011] Compared with the prior art, the advantages of the present utility model are that by setting a limit plate and a plunger assembly, the limit plate is arranged on the front side of the first linear guide rail and is fixed on the bed panel of the X-ray photography flat bed. The limit plate is provided with a plurality of through holes vertically penetrating. The plurality of through holes are spaced along the moving direction of the slider. The plunger assembly is installed on the film cassette. When the film cassette is installed on the slider, the plunger assembly is located below the limit plate. The plunger assembly can pass through the through hole from bottom to top to lock the film cassette and can also leave the through hole.

[0021] The present utility model will be further described in detail below in conjunction with the embodiments with reference to the drawings.

[0022] Embodiment 1: As shown in Figures 1 to 8As shown in the figure, a film cassette sliding locking device for an X-ray photography flat bed includes two sets of linear guide rails. On each set of linear guide rails, two sliders 1 capable of moving along them are respectively arranged. The two sets of linear guide rails are respectively called the first linear guide rail 2 and the second linear guide rail 3. The first linear guide rail 2 is arranged on the front side below the bed panel 4 of the X-ray photography flat bed and is fixed on the bed panel 4 of the X-ray photography flat bed. The second linear guide rail 3 is arranged on the rear side below the bed panel 4 of the X-ray photography flat bed and is fixed on the bed panel 4 of the X-ray photography flat bed. The film cassette sliding locking device of the X-ray photography flat bed further includes a limit plate 5 and a plunger assembly 6. The limit plate 5 is arranged on the front side of the first linear guide rail 2 and is fixed on the bed panel 4 of the X-ray photography flat bed. A plurality of vertically penetrating limit holes 7 are arranged on the limit plate 5, and the plurality of limit holes 7 are spaced apart along the moving direction of the slider 1. The plunger assembly 6 is installed on the film cassette 8. When the film cassette 8 is installed on the slider 1, the plunger assembly 6 is located below the limit plate 5. The plunger assembly 6 can pass through the limit hole 7 from bottom to top to lock the film cassette 8, and can also leave the limit hole 7.

[0023] In this embodiment, when the film cassette 8 needs to be used, first install the film cassette 8 on the four sliders 1, and then move the film cassette 8. The film cassette 8 will drive the four sliders 1 to move along the two sets of linear guide rails. When the film cassette 8 moves to the required position, operate the plunger assembly 6 to make the plunger assembly 6 pass through a limit hole 7 of the limit plate 5 directly above it from bottom to top. At this time, the plunger assembly 6 is blocked by the limit hole 7, and the film cassette 8 cannot move continuously, realizing the locking of the film cassette 8. When the film cassette 8 needs to be moved again, operate the plunger assembly 6 to make the plunger assembly 6 move downward to leave a limit hole 7 of the limit plate 5. At this time, the film cassette 8 can move. Thus, through the cooperation of the limit plate 5 and the plunger assembly 6, the locking of the film cassette 8 is realized. The locking effect is good, not easy to loosen, and the position relationship between the plunger assembly 6 and the limit hole 7 can be directly observed to judge the locking state, which is convenient to use.

[0024] Embodiment 2: This embodiment is basically the same as Embodiment 1, the difference being that: in this embodiment, as Figure 9 shown, the plunger assembly 6 includes a fixed block 9 and a rotating plunger 10. The fixed block 9 is installed on the outside of the film cassette 8. A vertically penetrating first threaded hole is arranged on the fixed block 9, and the rotating plunger 10 can pass through and be fixed at the first threaded hole.

[0025] In this embodiment, by inserting the rotating plunger 10 upward into the first threaded hole to make the rotating plunger 10 enter the limit hole 7, the locking of the film cassette 8 can be realized. By pulling out the rotating plunger 10 downward, the rotating plunger 10 can be made to leave the limit hole 7, realizing the unlocking of the film cassette 8, and the operation is convenient.

[0026] Embodiment 3: This embodiment is basically the same as Embodiment 2, except that: in this embodiment, the plunger assembly 6 further includes a fastening screw 11. A second threaded hole communicating with the first threaded hole is provided on the fixed block 9. The second threaded hole is arranged in the horizontal direction, and the fastening screw 11 can pass through the second threaded hole and be fixed.

[0027] In this embodiment, when the rotating plunger 10 is rotated into the limit hole 7 to lock the film cassette 8, the fastening screw 11 can be screwed into the second threaded hole so that the fastening screw 11 abuts against the rotating plunger 10 to prevent the rotating plunger 10 from rotating, further improving the locking reliability.

[0028] Embodiment 4: This embodiment is basically the same as Embodiment 1, except that: in this embodiment, each set of linear guides is realized by using a suspended rail, each slider 1 is realized by using a hanger wheel assembly, and hanger rail limiters 12 are respectively installed at both ends of each set of linear guides.

[0029] In this embodiment, the installation and limitation of the film cassette 8 are realized through the combination of a suspended rail, a hanger wheel assembly and a hanger rail limiter, which are conventional in the current industry. It is light in weight, low in cost, and can be installed in a hidden manner, with very little exposed part on the front, increasing the overall aesthetic degree of the X-ray photography flat bed.
