Description

Technical Field

[0001] This utility model belongs to the field of heat treatment furnace technology, and specifically relates to an automatic furnace lid locking device. Background Technology

[0002] Pit-type heat treatment furnaces are commonly used equipment in heat treatment processes. To ensure the heat treatment effect, the furnace cover of a pit-type heat treatment furnace is sealed during operation. Currently, the furnace cover of existing pit-type heat treatment furnaces is manually sealed by tightening nuts. This is not only time-consuming, labor-intensive, and inefficient, but also prone to omissions that result in incomplete sealing, posing potential risks to production safety and product quality.

[0003] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0004] The purpose of this utility model is to provide an automatic furnace lid locking device, thereby overcoming the defects in the prior art.

[0005] To achieve the above objectives, this utility model provides an automatic furnace lid locking device, including a furnace lid, a locking mechanism, and an opening and closing mechanism. The furnace lid is disposed at the furnace body opening, and the locking mechanism and opening and closing mechanism are disposed on the furnace body. The locking mechanism is located on the outer periphery of the furnace lid, and the opening and closing mechanism is connected to the locking mechanism. The locking mechanism includes a locking ring, a support member, and a pressing member. The locking ring is disposed on the outer periphery of the furnace lid, the support member is disposed on the furnace body, the bottom of the locking ring contacts the support member, and a pressing member is disposed on the locking ring, which contacts the top surface of the furnace lid. The output end of the opening and closing mechanism is connected to the locking ring. The opening and closing mechanism drives the locking ring to rotate clockwise on the support member, and the pressing member applies downward pressure to the furnace lid, thus sealing the furnace lid.

[0006] Preferably, in the technical solution, the locking ring has a “]” shaped structure, with an inner cavity formed on the inner side of the locking ring. The inner cavity covers the outer periphery of the furnace cover, and the lower end of the inner cavity contacts the lower end of the outer edge of the furnace body opening. A clamping element is provided at the upper end of the inner cavity.

[0007] Preferably, in the technical solution, the clamping component includes an upper wedge block and a lower wedge block. The upper wedge block is disposed at the upper end of the inner cavity, and the lower wedge block is disposed at the top surface of the furnace cover. The upper wedge block and the lower wedge block are disposed opposite to each other, and the structures of the upper wedge block and the lower wedge block are adapted to each other. During the rotation of the locking ring, the upper wedge block applies downward pressure to the lower wedge block, and the furnace cover is locked and sealed.

[0008] Preferably, in the technical solution, the support member is a roller mechanism, and the support member and the locking ring are subject to rolling friction.

[0009] Preferably, in the technical solution, a guide roller is provided on the locking ring. The guide roller is horizontally positioned and contacts the outer edge of the furnace body opening to guide the rotation of the locking ring.

[0010] Preferably, in the technical solution, the opening and closing mechanism includes a cylinder, a cylinder seat, and a connecting plate. The cylinder seat is mounted on the furnace body, the cylinder is mounted on the cylinder seat, and the connecting plate is mounted on the locking ring. The output end of the cylinder is connected to the connecting plate. The cylinder pushes the connecting plate, causing the locking ring to rotate clockwise.

[0011] Preferably, in the technical solution, the opening and closing mechanisms are symmetrically arranged on the furnace body, so that the locking ring rotates more smoothly.

[0012] Compared with the prior art, the present invention has the following beneficial effects: The furnace cover is locked and sealed by a locking device, replacing the original manual sealing method of tightening nuts. This improves efficiency, avoids incomplete sealing caused by omissions, and eliminates potential risks to production safety and product quality. Attached Figure Description

Detailed Implementation

[0014] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0015] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.

[0016] like Figure 1-4As shown, an automatic furnace lid locking device includes a furnace lid 1, a locking mechanism 2, and an opening / closing mechanism 3. The furnace lid 1 is located at the furnace body opening 4. The locking mechanism 2 and the opening / closing mechanism 3 are located on the furnace body 5. The locking mechanism 2 is located on the outer periphery of the furnace lid 1, and the opening / closing mechanism 3 is connected to the locking mechanism 2. The locking mechanism 2 includes a locking ring 20, a support member 21, and a pressing member 22. The locking ring 20 has a "]" shaped structure, and an inner cavity 200 is formed on the inner side of the locking ring 20. The inner cavity 200 covers the outer periphery of the furnace lid 1, and the lower end of the inner cavity 200 contacts the lower end of the outer edge of the furnace body opening 4. The support member 21 is located on the furnace body 5 and is a roller mechanism. The bottom of the locking ring 20 is connected to the support member 21. The support member 21 and the locking ring 20 are in contact, with rolling friction. The clamping member 22 includes an upper wedge block 220 and a lower wedge block 221. The upper wedge block 220 is located at the upper end of the inner cavity 200, and the lower wedge block 221 is located at the top surface of the furnace cover 1. The upper wedge block 220 and the lower wedge block 221 are arranged opposite to each other, and their structures are compatible. The opening and closing mechanism 3 includes a cylinder 30, a cylinder seat 31, and a connecting plate 32. The cylinder seat 31 is located on the furnace body 5, the cylinder 30 is located on the cylinder seat 31, and the connecting plate 32 is located on the locking ring 20. The output end of the cylinder 30 is connected to the connecting plate 32. The opening and closing mechanism 3 is symmetrically arranged on the furnace body 5, making the rotation of the locking ring 20 more stable. A guide roller 201 is provided on the locking ring 20. The guide roller 201 is horizontally arranged and contacts the outer edge of the furnace body opening 4 to guide the rotation of the locking ring 20.

[0017] During operation, cylinder 30 is activated, pushing connecting plate 32 to rotate locking ring 20 clockwise. As locking ring 20 rotates, upper wedge block 220 contacts lower wedge block 221, applying downward pressure to lower wedge block 221, thus locking and sealing furnace cover 5. This replaces the original manual sealing method of tightening nuts, improving efficiency, avoiding incomplete sealing caused by omissions, and eliminating potential safety and product quality hazards.
