Technical Field

[0001] This utility model relates to the technical field of head clips, specifically a bilateral lens dose measurement head clip. Background Technology

[0002] Currently, bilateral lens dose monitoring is performed on interventional radiology staff. However, only unilateral dose monitoring frames are available on the market, which are expensive and the frame design is not suitable for nearsighted people. The current solution is to use adhesive tape to clip the two doses together for monitoring, which is easy to fall off and inconvenient. Therefore, the bilateral lens dose measurement head clip applied for in this application was designed for monitoring. Summary of the Invention

[0003] To solve the above-mentioned technical problems, this utility model provides a bilateral lens dose measurement head clip that facilitates the installation of the device for users with different head sizes, improves the installation efficiency and effect, avoids the dose falling off during use, and enhances the practicality of the device.

[0004] The present invention relates to a bilateral lens dose measurement head clip, comprising a head clip body with a semi-circular structure, wherein rotating rods are respectively provided at both ends of the head clip body. The head clip body can clamp the human head, and the rotating rods can rotate relative to the head clip body. The bottom ends of the two rotating rods are provided with fixing grooves, and the fixing grooves are provided with chucks for fixing detectors. The fixing grooves are fixedly connected to the cover.

[0005] Preferably, the head clip body has two symmetrically arranged sliding mechanisms inside, each of which is fixedly connected to the inside of the head clip body through a limiting mechanism. Each sliding mechanism includes a sliding plate, which is slidably connected to the inner wall of the head clip body. Multiple limiting grooves are formed on the outer wall of the sliding plate. Two rotating shafts are symmetrically rotated and mounted on the bottom area of ​​the sliding plate. A rotating rod is fixedly mounted on each rotating shaft, and a fixing plate is fixedly mounted on the top of each rotating rod. The fixing plate is fixedly connected to the outer wall of the sliding plate through a spring. This bilateral lens dosimetry head clip, through the sliding operation of the sliding plate inside the head clip body, synchronously drives the rotating shafts, rotating rods, and fixing grooves to extend, installing the detector inside the fixing groove. The extension and contraction of the spring synchronously drives the fixing plate and rotating rod to adjust their angles under the limiting of the rotating shafts. Simultaneously, the movement of the rotating rod drives the simultaneous movement of the fixing groove, allowing it to fit tightly against the user's face, thus completing the installation of the device. This facilitates installation for users with different head sizes, improves installation efficiency and effectiveness, prevents the dose from falling off during use, and enhances practicality.

[0006] Preferably, the limiting mechanism includes a locking block, which is slidably connected to one of the limiting grooves opened on the slide plate. A sliding groove is opened on the outer side wall of the head clamp body. A screw is screwed onto the top of the locking block. A clamping plate is fixedly installed on the outer side wall of the screw. The clamping plate is tightly fitted to the outer side wall of the head clamp body. The screw is located inside the sliding groove. By rotating the screw, the clamping plate is simultaneously driven to fit tightly to the outer side wall of the head clamp body. Then, the locking block is slidably connected to the limiting groove, thereby completing the limiting and fixing operation of the slide plate inside the head clamp body.

[0007] Preferably, a limiting plate is fixedly installed on the inner side wall of the head clamp body, and multiple rolling balls are rolled on the outer side wall of the limiting plate. Each rolling ball is in contact with the outer side wall of the slide plate. The slide plate, which is used for sliding operations, contacts the rolling balls, thereby facilitating the sliding operation of the slide plate inside the head clamp body.

[0008] Preferably, a fixing cylinder is fixedly installed on the outer wall of the cover, and the fixing cylinder is screwed to the outer wall of the fixing groove. By installing the fixing cylinder, the stability of the cover and the fixing groove during the fixing operation is improved.

[0009] Preferably, the cover is provided with a snap-fit ​​protrusion, and the fixing groove is provided with a snap-fit ​​groove, and the snap-fit ​​protrusion and the snap-fit ​​groove are engaged to snap together.

[0010] Preferably, the snap-fit ​​protrusion penetrates the slot and extends to the outside of the slot.

[0011] Preferably, when the depth of the fixing groove is less than the height of the detector, the cover is provided with a receiving groove for accommodating the detector, and there is a pressure-resistant gap between the bottom of the receiving groove and the detector.

[0012] Preferably, a sponge is fixedly installed on the outer side wall of the head clamp body. By installing the sponge, the comfort of the head clamp body when it fits the user's head is improved.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the bilateral lens dose measurement head clip is made of materials such as polyethylene to make a head clip with appropriate tightness, and the two sides are provided with fixing grooves to place the detector, and the tight fixed cover prevents the detector from falling off.

[0014] The sliding motion of the slide plate within the head clamp body synchronously drives the rotating shaft, rotating rod, and fixing slot to extend, installing the detector inside the fixing slot. The extension and retraction of the spring synchronously adjusts the angle of the fixing plate and rotating rod within the limits of the rotating shaft. Simultaneously, the movement of the rotating rod moves the fixing slot, ensuring a tight fit with the user's face, thus completing the installation. This facilitates installation for users with different head sizes, improving installation efficiency and effectiveness, preventing the detector from falling off during use, and enhancing practicality.
