Description

Technical Field

[0001] This utility model relates to the field of X-ray detection, specifically a dual-path switching and locking structure for an X-ray detection instrument. Background Technology

[0002] In X-ray detection, single-path detection systems cannot simultaneously achieve the detection accuracy for both light and heavy elements. Therefore, hyperboloid curved crystals are introduced to construct dual-path systems, with the working optical path switched via a cutter. Currently, most cutter structures use a single motor directly connected to the cutter's rotation, with a photoelectric switch determining the cutter's position. This structure has low cutter position accuracy, and when the pump or motor inside the equipment vibrates, the cutter, which is not securely fastened, vibrates along with the vibration, affecting the measurement optical path. Therefore, new methods and approaches are needed. Utility Model Content

[0003] In view of this, this case mainly addresses the need to overcome at least one of the aforementioned defects in the prior art when conducting X-ray inspection.

[0004] This utility model provides a dual-path switching and locking structure for an X-ray detection instrument, including a support mechanism with an internal cavity, a beam cutter installed inside the cavity, and a positioning disk and a rotating block disposed outside the support mechanism;

[0005] The light cutter is connected to the positioning disk by a rotating shaft installed in the cavity and extending out of the support mechanism. The positioning disk has a slot for positioning and an elongated hole for rotating in conjunction with the rotating block.

[0006] The support mechanism is externally provided with a motor bracket for mounting the motor. The motor is connected to the rotating block, and the rotating block has a rotating shaft that cooperates with the elongated hole.

[0007] According to the background technology of this patent, most current beam cutting structures use a single motor directly connected to the beam cutter for rotation, and the position of the beam cutter is determined by a photoelectric switch. Such a structure has low beam cutting position accuracy, and when the pump or motor inside the equipment vibrates, the beam cutter is not secure and vibrates along with it, affecting the measurement optical path. However, the dual optical path switching and locking structure of the X-ray detection instrument disclosed in this utility model uses a photoelectric switch on the positioning plate and a photoelectric switch on the rotating block to determine the position of the beam cutter and the rotating block. The bearing fixed on the locking block cooperates with the slot of the positioning plate, and the locking is completed by the top spring. At the same time, the locking of the rotating block, the positioning plate and the beam cutter ensures that when the pump or motor inside the equipment vibrates, the beam cutter is secure and does not vibrate along with it, ensuring the stability of the measurement optical path and the accuracy of subsequent measurements.

[0008] In addition, the dual-optical-path switching and locking structure of the X-ray detection instrument disclosed in this utility model also has the following additional technical features:

[0009] Furthermore, the support mechanism includes a mounting base, an upper cover disposed above the mounting base, and a side cover disposed on the side of the mounting base. The mounting base, the upper cover, and the side cover form the aforementioned cavity. The lower end of the rotating shaft is mounted on the mounting base, and the upper end extends through the upper cover. The light cutter is fixedly mounted on the lower part of the rotating shaft, and the positioning plate having the groove is fixedly mounted on the upper part of the rotating shaft located outside the upper cover.

[0010] Furthermore, the light cutter is provided with a direct light hole and a side light path hole.

[0011] Furthermore, the upper cover is also provided with a positioning disk photoelectric switch, and the positioning disk is provided with a photoelectric switch baffle that cooperates with the positioning disk photoelectric switch.

[0012] Furthermore, the side cover is provided with a positioning bracket, the positioning bracket is provided with a clamping component and a locking block, and the locking block is provided with a rotating positioning component that cooperates with the slot for positioning.

[0013] Preferably, the clamping component is a spring, the rotating positioning component is a bearing, the spring is installed between the positioning bracket and the locking block, and the bearing is installed on the locking block rotating shaft provided on the locking block.

[0014] The slot is an arc-shaped structure that can mate with the bearing. The bearing is located in the middle of the card block with a hollow structure. The hollow structure can be a U-shaped structure or a rectangular hollow structure. The bearing is located in the U-shaped or rectangular hollow structure, which is not shown in the figure. The hollow structure can be a hollow structure with upper and lower supports. The card block can also be a plate-shaped structure. The bearing is located on the shaft mounted on the plate-shaped structure.

Figure 1-3 These are schematic diagrams of the structure of this utility model from different angles. Figure 2-8 This is a schematic diagram of different states and positions of an embodiment of this utility model.

[0030] like Figure 1-3 As shown, according to an embodiment of the present invention, it includes a support mechanism with an internal cavity, a light cutter installed inside the cavity, and a positioning disk and a rotating block disposed outside the support mechanism; the light cutter is synchronously rotated and connected to the positioning disk via a rotating shaft installed inside the cavity and extending outside the support mechanism, the positioning disk having a slot for positioning and an elongated hole for rotating in cooperation with the rotating block; a motor bracket for mounting a motor is disposed outside the support mechanism, the motor is connected to the rotating block, and the rotating block has a rotating actuation shaft for rotating in cooperation with the elongated hole.

[0031] According to an embodiment of the present invention, the support mechanism includes a mounting base, an upper cover disposed above the mounting base, and a side cover disposed on the side of the mounting base. The mounting base, the upper cover, and the side cover form the aforementioned cavity. The lower end of the rotating shaft is mounted on the mounting base, and the upper end extends through the upper cover. The light cutter is fixedly mounted on the lower part of the rotating shaft, and the positioning plate having the groove is fixedly mounted on the upper part of the rotating shaft located outside the upper cover.

[0032] According to an embodiment of the present invention, the light cutter is provided with a direct light hole and a side light path hole.

[0033] According to an embodiment of the present invention, the upper cover is further provided with a positioning disk photoelectric switch, and the positioning disk is provided with a photoelectric switch baffle that cooperates with the positioning disk photoelectric switch.

[0034] According to an embodiment of the present invention, the rotating shaft is connected to the top cover via a bearing and a bearing bracket. A positioning bracket is provided on the side cover. The positioning bracket is provided with a clamping component and a locking block. The locking block is provided with a rotating positioning component that cooperates with the slot for positioning.

[0035] Furthermore, the rotation positioning component is a bearing, the spring is installed between the positioning bracket and the locking block, and the bearing is installed on the locking block rotation shaft provided on the locking block.

[0036] The operating principle and procedures of the entire device:

[0037] The device determines the position of the cutter 6 and the rotating block 11 by using the photoelectric switch 7 on the positioning plate and the photoelectric switch 14 on the rotating block. The bearing 16 fixed on the locking block 18 cooperates with the slot of the positioning plate 9, and the locking is completed by the top spring 17.

[0038] Switching from the direct light path to the side light path, the initial state is as follows: Figure 4 As shown, at this time, the direct-view hole of the cutter 6 is located in the optical path, and the bearing 16 on the locking block 18 is located at the slot of the positioning plate 9, and is fixed and positioned by the clamping spring 17; as Figure 5 As shown, the motor 13 rotates, driving the rotating block 11 to rotate counterclockwise. The actuating shaft 10 on the rotating block 11 enters the slot of the positioning disk 9, driving the positioning disk 9 to rotate clockwise. The bearing 16 leaves the slot of the positioning disk 9, causing the light cutter 6 to rotate synchronously. At this time, the light cutter 6 exits the optical path through the direct-view hole. Figure 6 , 7 As shown, motor 13 rotates continuously, driving positioning disk 9 and light cutter 6 to rotate synchronously, cutting the side light path hole of light cutter 6 into the light path. At this time, bearing 16 on clamping block 18 is located at the slot of positioning disk 9 and is pressed and positioned by clamping spring 17; as Figure 8 As shown, the motor 13 rotates continuously, driving the rotating block 11 to rotate counterclockwise. The actuating shaft 10 on the rotating block 11 leaves the slot of the positioning disk 9. The rotating block 11 rotates until the photoelectric switch of the rotating block 14 stops, thus completing all the steps of switching the direct light path to the side light path.

[0039] Switching from the side beam path to the direct beam path simply requires reversing motor 13 to rotate rotating block 11 clockwise. Figure 8 , 7 All steps 6, 5, and 4 are followed to achieve optical path switching from the side optical path to the direct optical path and lock positioning.
