Description

Technical Field

[0001] The utility model relates to the technical field of doors, in particular to a heavy-duty manual radiation-proof door shaft. Background Art

[0002] The radiation-proof door of the hospital's radiology department is a specially designed door used to prevent radiation from leaking to other areas. The radiation-proof door of the radiology department is usually made of materials such as lead plates or lead glass, because lead can effectively block or absorb most of the radiation. At the same time, the sealing performance of the door is also very important to ensure that radiation does not leak out through the door gap.

[0003] Since radiation-proof doors are generally very heavy, with a door leaf weighing approximately 200-400kq, this places relatively high demands on the reliability of the door axis of the manual radiation-proof door, requiring the door axis to have strong locking properties. In the case of frequent opening and closing, the door axis will sink due to excessive pressure, causing the manual radiation-proof door leaf to come off the axis. Therefore, we proposed a heavy-duty manual radiation-proof door axis to solve the above problem. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that when the radiation-proof door is frequently opened and closed, the ordinary door shaft will sink due to excessive pressure, thereby causing the manual radiation-proof door leaf to come off the shaft, and a heavy-duty manual radiation-proof door shaft is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A heavy-duty manual radiation-proof door axis comprises a radiation-proof door and a door frame, wherein a mounting groove is provided on one side of the radiation-proof door, a axis box is embedded in the inner wall of the mounting groove, a axis pin is slidably connected to the top of the axis box, a limiting hole corresponding to the axis pin is provided on the top inner wall of the door frame, the axis pin is inserted into the limiting hole, and the axis further comprises:

[0007] A moving component is arranged inside the axial box and is used to drive the axial pin to move up and down;

[0008] The locking assembly is arranged inside the trunnion box and is used to lock the position of the trunnion pin and the door frame after they are assembled.

[0009] In a possible design, the movable component includes a fixed pin, which is fixedly arranged inside the axis box, and a simple pendulum connecting rod is rotatably connected to the fixed pin. A groove is provided on the top of the simple pendulum connecting rod, and a first movable pin is fixedly connected to the inner walls on both sides of the groove. A small connecting rod is rotatably connected to the first movable pin, and a second movable pin is fixedly connected to the top of the small connecting rod, and the bottom of the axis pin is rotatably connected to the second movable pin.

[0010] In a possible design, a clearance groove is provided on the single-pendulum connecting rod, and a hexagonal pull rod screw is arranged in the clearance groove. An internal threaded fixing sleeve is fixedly connected to the inner wall of one side of the axis box, and the internal threaded fixing sleeve is connected to the outer wall of one side of the axis box, and the hexagonal pull rod screw is threadedly connected to the inner wall of the internal threaded fixing sleeve.

[0011] In a possible design, the locking group includes a locking screw, which passes through one side of the axis box and is threadedly connected to the axis box. A limiting groove is provided on the axis pin, and one end of the locking screw is in conflict with an inner wall of one side of the limiting groove.

[0012] In a possible design, a fixed axial sleeve is provided on the internal sliding sleeve of the axial box on the axial pin, and the top of the fixed axial sleeve is fixedly connected to the top inner wall of the axial box.

[0013] In a possible design, a limit stop screw is threadedly connected to the inner wall of one side of the axis box, and the limit stop screw is parallel to one end of the hexagon socket pull rod screw, which is used to limit the hexagon socket pull rod screw when it moves inside the axis box.

[0014] In a possible design, a limiting ring is provided on the hexagon socket pull rod screw, and the limiting ring is fixedly connected to the internal threaded fixing sleeve. A compression spring is provided on the hexagon socket pull rod screw, and the two ends of the compression spring respectively conflict with one side of the limiting ring and one side of the simple pendulum connecting rod.

[0015] In the present application, when installing the radiation proof door, the single-pendulum connecting rod is rotated around the fixed pin by rotating the hexagonal pull rod screw. The rotation of the single-pendulum connecting rod will drive the movement of the small connecting rod and the second movable pin, thereby causing the axis pin to slide along the inside of the axis box, thereby allowing the axis pin to be inserted into the limit hole at the top of the door frame.

[0016] In order to ensure its stability and safety, the axis pin needs to be locked through a locking assembly. Specifically, the user can screw the locking screw into the axis box and interfere with the limit slot on the axis pin. In this way, the axis pin is firmly locked in the limit hole, so that the axis pin will always remain extended.

[0017] During use, the height of the axis pin is adjusted by rotating the hexagon socket pull rod screw. During the adjustment process, the compression spring will exert a certain elastic force on the single-pendulum connecting rod to keep it in a stable position. At the same time, the limit stop screw can limit the maximum movement distance of the hexagon socket pull rod screw to prevent it from excessive movement and causing the hexagon socket pull rod screw to fall off from the internal threaded fixing sleeve.

[0018] Beneficial effects:

[0019] In the utility model, the heavy-duty manual radiation-proof door axis is provided with a moving assembly, and the user can realize the up and down movement of the axis pin through simple operation, so as to conveniently install and disassemble the radiation-proof door;

[0020] In the utility model, the heavy-duty manual radiation-proof door axle is designed with a locking assembly so that when the radiation-proof door is installed, the axle pin will remain in an extended state, thereby ensuring the stability and safety of the radiation-proof door.

[0021] In the utility model, the heavy-duty manual radiation-proof door axis can adjust the height of the axis pin according to actual conditions by arranging a hexagonal pull rod screw and a compression spring, thereby preventing the door axis from sinking and falling off due to long-term use of the radiation-proof door.

[0022] In the utility model, through the design of the locking assembly, when the radiation proof door is installed, the axis pin will always remain in an extended state to ensure the stability and safety of the radiation proof door. By arranging the hexagonal pull rod screw and the compression spring, the height of the axis pin can be adjusted according to actual conditions to prevent the door axis from sinking and falling off due to long-term use of the radiation proof door.

The tianzhu pin 10 passes through the top of the tianzhu box 3 through a sliding connection and matches the limiting hole on the top of the door frame 2 to realize the installation and fixation of the door.

[0031] Connection between the fixed pin and the simple pendulum connecting rod: First, a fixed pin 6 is fixedly set inside the axis box 3. The fixed pin 6 serves as a supporting point, and the simple pendulum connecting rod 5 is rotatably connected thereto. A groove is designed on the top of the simple pendulum connecting rod 5, and the first movable pin 7 is fixed on the inner walls on both sides of the groove. The first movable pin 7 is rotatably connected to the small connecting rod 8.

[0032] Connection between the small connecting rod and the sky axis pin: The top of the small connecting rod 8 passes through and is fixedly connected with the second movable pin 9, and the bottom of the sky axis pin 10 is rotatably connected with the second movable pin 9. In this way, by operating the single pendulum connecting rod 5, the small connecting rod 8 and the sky axis pin 10 can be driven to move up and down, and the sky axis pin 10 can be inserted into the limiting hole of the door frame 2 to complete the installation.

[0033] In order to facilitate the control of the movement of the single-pendulum connecting rod 5, a hexagon socket pull rod screw 12 is specially arranged inside the axis box 3. The screw passes through the give way groove on the single-pendulum connecting rod 5 and is threadedly connected to the internal threaded fixing sleeve 11 fixed on the inner wall of one side of the axis box 3. By rotating the hexagon socket pull rod screw 12, the single-pendulum connecting rod 5 can be pushed or pulled, thereby controlling the lifting and lowering of the axis pin 10, and then the height of the axis pin 10 can be adjusted according to actual conditions to adjust the axis, thereby preventing the door axis from sinking and falling off due to long-term use of the radiation-proof door.

[0034] In order to achieve position locking of the axis pin 10 and the door frame 2 after assembly, a locking assembly is designed in this embodiment. Specifically, a locking screw 14 is arranged through one side of the axis box 3, and the screw is threadedly connected to the axis box 3. A limiting groove is provided on the axis pin 10. When the axis pin 10 is adjusted to a suitable position, the locking screw 14 is rotated so that one end of it contacts the inner wall of one side of the limiting groove, thereby achieving the locking function.
