Description

Technical Field

[0001] This utility model relates to the technical field of rigid steel grain depot-specific airtight windows, specifically a rigid steel grain depot-specific airtight window that is easy to install. Background Technology

[0002] Grain depot is short for grain warehouse, a common term for grain storage enterprises. These are state-owned enterprises and an important component of China's grain enterprises. They are uniformly managed by the grain department and serve as the main channel for national and local grain reserves and grain circulation. Their main tasks are to complete all aspects of grain circulation, including receiving, storing, and transporting grain. Sealed windows are indispensable in grain depots. These windows, working in conjunction with the ventilation ducts within the grain warehouse, allow for air exchange between the inside and outside, while also increasing the warehouse's airtightness, making them widely used in the grain depot sector.

[0003] When connecting existing sealed windows to steel frames on walls, two or more operators are required to align the sealed window with the steel frame. One operator holds the sealed window still while another operator uses bolts to install the sealed window and steel frame. Because the steel frame requires a large number of bolts, the installation process is lengthy. During the alignment process, the sealed window may gradually tilt due to hand fatigue, leading to deviations in the installation position. To address this issue, we propose a high-strength steel grain depot-specific sealed window that is easy to install. Utility Model Content

[0004] The purpose of this invention is to provide a rigid steel grain depot-specific airtight window that is easy to install, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rigid steel grain depot-specific airtight window that is easy to install, comprising an airtight window body and a steel frame supporting the airtight window body. Positioning blocks are fixedly installed on the surface of the airtight window body, and circular blocks are fixedly installed on the inner wall of the steel frame. A control component is provided within the airtight window body and the steel frame, and the control component includes:

[0006] A through hole for inserting a rotating rod;

[0007] A circular groove, which is used to limit the rotating rod;

[0008] The positioning component is used to pre-fix the airtight window body, thereby completing the initial installation of the airtight window body and the steel frame and avoiding misalignment during subsequent installation.

[0009] Preferably, the surface of the circular block has a through hole, and the inside of the circular block has a circular groove. When the rotating rod is located in the circular groove and intersects with the through hole, the movement of the rotating rod can be restricted.

[0010] Preferably, the positioning block is penetrated by a rotating rod and rotatably connected to the rotating rod. A threaded rod is fixedly installed on the surface of the rotating rod. The threaded rod penetrates the cylinder and is fixedly connected to the cylinder. The threaded rod penetrates the positioning block and is rotatably connected to the positioning block. The surface of the positioning block is rotatably connected to the turntable. When the turntable rotates, the threaded rod can drive the cylinder and the rotating rod to perform synchronous circumferential motion.

[0011] Preferably, the cylinder passes through the ring and is fixedly connected to the ring, and the surface of the ring is provided with a groove, which can restrict the rotation of the ring and the cylinder.

[0012] Preferably, a fixing frame is fixedly installed on the surface of the positioning block, the inner wall of the fixing frame is fixedly connected to one end of the spring, and the other end of the spring is fixedly installed on the surface of the pressure plate. When the pressure plate is no longer under force, it can spring up under the support of the spring.

[0013] Preferably, a pressure rod is fixedly installed on the surface of the pressure plate. The pressure rod passes through the positioning block and is slidably connected to the positioning block. When the pressure plate moves, the pressure rod fixed on the surface of the pressure plate can slide synchronously within the positioning block.

[0014] Preferably, a limiting rod is fixedly installed at the bottom of the pressure rod, and the limiting rod fixed to the surface of the pressure rod can move synchronously when the pressure rod moves.

[0015] Compared with the prior art, this utility model provides a rigid steel grain depot-specific airtight window that is easy to install and has the following advantages:

[0016] 1. This easy-to-install rigid steel grain depot-specific airtight window is equipped with a control component. When the turntable is turned on the surface of the positioning block, the threaded rod and cylinder fixed on the surface of the turntable can rotate synchronously on the inner wall of the positioning block. When the threaded rod rotates, the rotating rod fixed on the surface of the threaded rod can rotate synchronously on the surface of the positioning block. After rotation, the rotating rod can form an interlocking shape with the through hole, and then the rotating rod can be locked into the circular groove, thereby completing the initial installation of the airtight window body and the steel frame, avoiding installation misalignment during subsequent installation.

[0017] 2. This easy-to-install rigid steel grain depot-specific airtight window features a positioning component. When the cylinder rotates, the ring fixed to the cylinder surface rotates synchronously. The ring surface has a groove, so after pre-fixing, when the pressure applied to the pressure plate is released, the pressure plate can spring up under the support of the spring. The pressure rod fixed to the pressure plate surface can drive the limiting rod to engage in the groove on the ring surface, thus restricting the rotation of the cylinder and the threaded rod. This method enhances the stability of the airtight window body and the steel frame after initial fixing. Attached Figure Description

Detailed Implementation

[0023] like Figures 1-4 As shown, this utility model provides a technical solution: a rigid steel grain depot-specific airtight window that is easy to install, comprising an airtight window body 1 and a steel frame 3 supporting the airtight window body 1. Positioning blocks 2 are fixedly installed on the surface of the airtight window body 1, and circular blocks 4 are fixedly installed on the inner wall of the steel frame 3. A control component 5 is provided inside the airtight window body 1 and the steel frame 3. The control component 5 includes: a through hole 51, a circular groove 52, a rotating rod 53, and a positioning element 54. The positioning element 54 is used for preliminary pre-fixation of the airtight window body 1, and the positioning blocks 2 are positioned on the surface of the window body 1. When the turntable 543 is rotated, the threaded rod 541 and the cylinder 542 fixed on the surface of the turntable 543 can rotate synchronously on the inner wall of the positioning block 2. When the threaded rod 541 rotates, the rotating rod 53 fixed on the surface of the threaded rod 541 can rotate synchronously on the surface of the positioning block 2. After rotation, the rotating rod 53 can form an interlocking shape with the through hole 51, so that the rotating rod 53 can be inserted into the circular groove 52, thereby completing the initial installation of the airtight window body 1 and the steel frame 3, and avoiding misalignment during subsequent installation.

[0024] The circular block 4 has a through hole 51 on its surface and a circular groove 52 inside. When the rotating rod 53 is located in the circular groove 52 and intersects with the through hole 51, the movement of the rotating rod 53 can be restricted. The positioning block 2 is penetrated by the rotating rod 53 and is rotatably connected to the rotating rod 53. A threaded rod 541 is fixedly installed on the surface of the rotating rod 53. The threaded rod 541 penetrates the cylinder 542 and is fixedly connected to the cylinder 542. The threaded rod 541 penetrates the positioning block 2 and is rotatably connected to the positioning block 2. The surface of the positioning block 2 is rotatably connected to the turntable 543. When the turntable 543 rotates, the threaded rod 541 can drive the cylinder 542 and the rotating rod 53 to perform synchronous circumferential motion. The cylinder 542 penetrates the ring 544 and is fixedly connected to the ring 544. The surface of the ring 544 has a retaining groove 545. The retaining groove 545 can restrict the rotation of the ring 544 and the cylinder 542. A fixing frame 546 is fixedly installed on the surface of the positioning block 2. The inner wall of the fixing frame 546 is fixedly connected to one end of the spring 548, and the other end of the spring 548 is fixedly installed on the surface of the pressure plate 547. When the pressure plate 547 is no longer under force, it can spring up under the support of the spring 548. A pressure rod 549 is fixedly installed on the surface of the pressure plate 547. The pressure rod 549 passes through the positioning block 2 and is slidably connected to the positioning block 2. When the pressure plate 547 moves, the pressure rod 547 fixed on the surface of the pressure plate 549 can slide synchronously within the positioning block 2. A limit rod 540 is fixedly installed at the bottom of the pressure rod 549. When the pressure rod 549 moves, the limit rod 540 fixed on the surface of the pressure rod 549 can move synchronously.

[0025] In this utility model, when it is necessary to install the airtight window body 1 on the steel frame 3 on the wall of the grain depot, the rotating rod 53 in the positioning block 2 is aligned with the through hole 51 and inserted. The rotating rod 53 and the through hole 51 are kept parallel and in contact. After contact, the rotating rod 53 is inserted from the through hole 51 into the circular groove 52. After insertion, the positioning block 2 and the airtight window body 1 are in contact with the surface of the steel frame 3. After contact, the pressure plate 547 is moved on the surface of the positioning block 2. The pressure plate 547 is subjected to force and moves longitudinally within the positioning block 2. The pressure rod 549 fixed on the surface of the pressure plate 547 can drive the limiting rod 540 to move out of the slot 545 opened on the surface of the ring 544. After moving out, the pushing force is maintained, and the turntable 543 is moved on the surface of the positioning block 2. When the turntable 543 rotates, the threaded rod 541 and the cylinder 549 fixed on the surface of the turntable 543 are in contact with the steel frame 3. 42 can rotate synchronously on the inner wall of the positioning block 2. When the threaded rod 541 rotates, the rotating rod 53 fixed on the surface of the threaded rod 541 can rotate synchronously on the surface of the positioning block 2. After rotation, the rotating rod 53 can form an interlaced shape with the through hole 51, and then the rotating rod 53 can be inserted into the circular groove 52, thereby completing the initial installation of the airtight window body 1 and the steel frame 3, avoiding misalignment during subsequent installation. After installation, the pressure applied to the pressure plate 547 is released, and the pressure plate 547 can spring up under the support of the spring 548. The pressure rod 549 fixed on the surface of the pressure plate 547 can drive the limiting rod 540 to be inserted into the slot 545 opened on the surface of the ring 544, thus restricting the rotation of the cylinder 542 and the threaded rod 541. This method can enhance the stability of the airtight window body 1 and the steel frame 3 after initial fixing.

[0026] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
