Description

A self-locking boiler door Technical Field

[0001] This utility model relates to the field of boiler furnace door technology, specifically a self-locking boiler furnace door. Background Technology

[0002] A boiler furnace door is a type of furnace door with an ash trough. It typically includes a circular furnace door seat and a furnace door cover. Its characteristic feature is that a semi-circular ash trough matching the diameter of the furnace is placed inside the furnace door seat. The ash trough is connected by round steel to ensure stability. The furnace door cover and the furnace door seat are connected by a connecting rod, which allows the fire sealing hole to be precisely aligned. The front end of the ash trough fits perfectly with the inner wall of the furnace.

[0003] When the boiler door is locked, it is closed by handwheel. However, after closing, the door cannot be effectively locked and fixed around the perimeter. The pressure around the door is uneven, resulting in a loose overall closure.

[0004] Therefore, we propose a novel self-locking boiler door to solve the above-mentioned technical problems. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a self-locking boiler door, which solves the problem that the boiler door cannot effectively lock automatically around its perimeter when locked, resulting in a less than tight seal.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a self-locking boiler door, comprising:

[0009] Furnace door body;

[0010] A furnace door rotating mechanism is fixedly connected to the outer wall of the furnace door body, and the other end of the furnace door rotating mechanism is fixedly connected to the boiler body.

[0011] A protruding locking mechanism is fixedly connected to both ends of the furnace door body;

[0012] A locking and limiting mechanism is located outside the protruding locking mechanism and is installed on the boiler body.

[0013] Preferably, the furnace door body includes a furnace door shell, a furnace door handle is fixedly connected to the outer end of the furnace door shell, a furnace door rotating mechanism is fixedly connected to the lower end of the furnace door shell, side mounting grooves are opened on the inner sides of both ends of the furnace door shell, a handwheel panel is fixedly connected to the upper end of the furnace door shell, a locking handwheel screw is rotatably connected to the inner side of the handwheel panel, and a protruding locking mechanism is installed on the furnace door shell through the side mounting grooves.

[0015] Preferably, the protruding locking mechanism includes a hollow sleeve plate. An abutment rod is sleeved on the inner side of the lower end of the hollow sleeve plate. An abutment block is sleeved on the upper end of the abutment rod inside the hollow sleeve plate. A pull-back spring is installed on the lower end of the abutment block around the abutment rod. An inclined abutment block is sleeved on the upper part of the abutment block inside the hollow sleeve plate. A connecting spring is fixed between the inclined abutment block and the hollow sleeve plate. A locking protrusion passing through the hollow sleeve plate is fixed on the outer end of the inclined abutment block. The hollow sleeve plate is sleeved on the furnace door shell. A locking limiting mechanism is installed on the outer side of the locking protrusion. A semi-circular protrusion is fixed on the outer wall of the upper end of the hollow sleeve plate.

[0019] (III) Beneficial Effects

[0020] Compared with the prior art, the present invention provides a self-locking boiler door, which has the following advantages:

[0021] 1. This utility model features a protruding locking mechanism that automatically protrudes when the furnace door body is locked. The protruding locking mechanism automatically protrudes and locks itself in the locking limit mechanism, ensuring that the furnace door body is evenly compressed when closed, resulting in a tighter seal.

[0022] 2. This utility model features a protruding locking mechanism structure, which facilitates pressing and closing through contact. When the contact rod of the protruding locking mechanism contacts the boiler body, it retracts inward. The contact rod then drives the contact block to retract and move inward within the hollow sleeve plate. This causes the contact block to cause the pull spring to deform, and the pull spring has a deformation pulling force. When the contact force disappears, the entire structure can be restored. When the contact block contacts the inclined contact block, it presses, causing the inclined contact block to move outward. When the inclined contact block moves outward, it presses and deforms the connecting spring, thus having a deformation restoration force. When the pressing force disappears, the entire structure can be restored. When the inclined contact block is pressed, it can cause the locking protrusion to move outward. The locking protrusion can then be exposed and fitted into the locking limiting mechanism for limiting and fixing. The hollow sleeve plate is fitted onto the furnace door shell, allowing for corresponding installation. Attached Figure Description

[0031] Example 1

[0032] This embodiment provides a technical solution: a self-locking boiler door, as shown in Figures 1-5, including a door body, a door rotation mechanism, a protruding locking mechanism, and a locking limit mechanism.

[0033] The furnace door rotating mechanism is fixed to the outer wall of the furnace door body. The furnace door body can be rotated and opened and closed through the furnace door rotating mechanism. The other end of the furnace door rotating mechanism is fixedly connected to the boiler body. The furnace door body can be opened and closed on the boiler body through the furnace door rotating mechanism. The protruding locking mechanism is fixed to both ends of the furnace door body. The furnace door body can be protruded and locked in place through the protruding locking mechanism. The locking limit mechanism is located outside the protruding locking mechanism. The protruding locking mechanism can be protruded and positioned in the locking limit mechanism, so that it can be effectively limited in installation. The locking limit mechanism is installed on the boiler body, so that it can be installed and placed accordingly.

[0034] The number of protruding locking mechanisms and locking limit mechanisms corresponds, allowing for corresponding installation and connection.

[0035] The furnace door body includes a furnace door shell 2, which can be closed and covered. A furnace door handle 21 is fixed to the outer end of the furnace door shell 2 for easy gripping and opening and closing. A furnace door rotating mechanism is fixed to the lower end of the furnace door shell 2, which can rotate to open and close. Side mounting grooves 22 are provided on the inner sides of both ends of the furnace door shell 2. A protruding locking mechanism is installed on the furnace door shell 2 through the side mounting grooves 22, which can be correspondingly limited for installation. A handwheel panel 11 is fixed to the upper end of the furnace door shell 2, which can be correspondingly installed and placed. A locking handwheel screw 1 is rotatably connected to the inner side of the handwheel panel 11. The locking handwheel screw 1 can be threaded and rotated on the handwheel panel 11, which can be threaded and rotated to be installed and connected to the furnace door body.

[0036] The furnace door rotating mechanism includes a concave end block 4, which is fixed to the lower end of the furnace door housing 2 so that it can be installed and placed accordingly. A rotating connecting block 41 is sleeved inside the concave end block 4. The rotating connecting block 41 can rotate within the concave end block 4. The concave end block 4 and the rotating connecting block 41 are movably connected by a positioning shaft 6. The rotating connecting block 41 can be positioned and rotated within the concave end block 4 by the positioning shaft 6.

[0037] As shown in Figures 1 and 2, the protruding locking mechanism includes a hollow sleeve plate 5. A semi-circular protrusion 53 is fixedly connected to the upper outer wall of the hollow sleeve plate 5. An installation screw 52 is installed on the inner side of the semi-circular protrusion 53. The semi-circular protrusion 53 is fixed to the furnace door shell 2 by the installation screw 52, ​​so that the hollow sleeve plate 5 can be installed accordingly. An abutting end rod 54 is sleeved on the lower inner side of the hollow sleeve plate 5. When the abutting end rod 54 contacts the boiler body, it retracts inward. The upper end of rod 54 is fitted with an abutting end block 541 inside the hollow sleeve 5. The abutting end rod 54 drives the abutting end block 541 to retract and move inward within the hollow sleeve 5. The lower end of the abutting end block 541 is fitted with a pull-back spring 542 around the abutting end rod 54. The other end of the pull-back spring 542 is fixed to the hollow sleeve 5. Thus, the abutting end block 541 drives the pull-back spring 542 to stretch and deform, and the pull-back spring 542 has a stretching force. When the resistance disappears, the whole structure can be restored. Above the contact block 541, inside the hollow sleeve plate 5, is a sloping contact block 511. When the contact block 541 contacts the sloping contact block 511, it is squeezed, causing the sloping contact block 511 to move outward. A connecting spring 512 is fixed between the sloping contact block 511 and the hollow sleeve plate 5. When the sloping contact block 511 moves outward, it squeezes the connecting spring 512 to deform, thus having a deformation restoration force. When the squeezing force disappears, the whole structure can be restored. The outer end of the sloping contact block 511 is fixed with a locking protrusion 51 that passes through the hollow sleeve plate 5. When the sloping contact block 511 is squeezed, it can drive the locking protrusion 51 to move outward. A locking limiting mechanism is installed on the outside of the locking protrusion 51. The locking protrusion 51 can be exposed and sleeved in the locking limiting mechanism for limiting and fixing. The hollow sleeve plate 5 is sleeved on the furnace door shell 2, so that they can be installed accordingly.

[0038] The locking and limiting mechanism includes a locking sleeve plate 3. A furnace body mounting plate 31 is fixedly connected to the lower end of the locking sleeve plate 3. The furnace body mounting plate 31 is installed on the boiler body by screws, so that it can be installed accordingly. The furnace body mounting plate 31 can drive the locking sleeve plate 3 to be placed stably. A locking sleeve groove 32 is opened on the inner side of the upper end of the locking sleeve plate 3. The locking sleeve plate 3 passes through the area of ​​the locking sleeve groove 32, so that the locking protrusion 51 can protrude and be positioned in the locking sleeve groove 32, thereby locking and fixing it.

[0039] The locking sleeve groove 32 corresponds to the position of the locking protrusion 51, so that they can be installed and connected accordingly.

[0040] In use, the furnace door body can be rotated and opened and closed via the furnace door rotation mechanism. The furnace door body can be opened and closed on the boiler body via the furnace door rotation mechanism. The protruding locking mechanism is fixed to both ends of the furnace door body. The furnace door body can be protruded and locked in position via the protruding locking mechanism.
