Description

Technical Field

[0001] This utility model belongs to the field of fireproof protective covers, specifically, it relates to a quick-opening device for the inspection door of a fireproof protective cover. Background Technology

[0002] During the operation of industrial equipment, fireproof protective covers are typically used to insulate and protect electrical components, pipe connections, or mechanical transmission parts from the impact of high temperatures, flames, or flying debris on the surrounding environment. However, during long-term use, the internal components of the fireproof cover require periodic inspection, maintenance, or replacement, often necessitating opening the cover for operation. Most existing fireproof cover structures use bolts or screws for fixing. When maintenance is needed, workers must use tools to disassemble each fastener individually, which is not only cumbersome and time-consuming but also poses certain safety risks when performing disassembly and assembly in high-temperature or confined spaces. Furthermore, repeated disassembly of screws can easily cause wear on the threaded holes or deformation of the fireproof plate, reducing the sealing performance and service life of the fireproof cover.

[0003] To address these issues, some devices have attempted to achieve partial opening by using hinged door panels. However, due to the fixed structure and difficulty in adjusting the gaps, door panels often fail to seal properly or the latches become loose, failing to meet the reliable sealing requirements of the equipment under high temperature and vibration environments. Furthermore, traditional latch structures generally employ a single-point locking design. When the fireproof cover panel deforms due to heat, the inspection door is prone to warping or disengagement from the cover, affecting fire resistance and safety.

[0004] In view of this, this utility model is hereby proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a quick-opening device for a fireproof protective cover inspection door, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A quick-opening device for a fireproof protective cover inspection door includes: a fireproof protective cover panel, wherein an opening for maintenance operations is provided on one side of the fireproof protective cover panel, and an inspection door is engaged at the opening;

[0008] The inspection door and the fireproof protective cover panel are detachably connected by four sets of snap-fit ​​components.

[0009] Each set of the snap-fit ​​assembly includes two quick-opening buckles arranged at 90° to each other and fixedly installed on the side of the inspection door. A buckle seat corresponding to the position of the quick-opening buckle is also fixedly connected to one side of the inspection door. The quick-opening buckle and the buckle seat are interlocked.

[0010] A connecting piece corresponding to the position of the buckle is fixedly connected to one side of the fireproof protective cover panel. An adjustment mechanism is provided above the buckle to adjust the distance between the buckle and the connecting piece.

[0011] Optionally, the adjusting mechanism includes a connecting cylinder fixedly installed above the buckle seat, with side plates fixedly connected to both sides of the connecting cylinder, and the connecting piece slidably disposed inside the connecting cylinder and located below the side plates.

[0012] Optionally, a rotating rod is rotatably connected between the two side plates. A spiral plate is sleeved on the periphery of the rotating rod. Several through slots that cooperate with the spiral plate are opened on the opposite side of the connecting plate. The plate-like structure of the spiral plate is inserted into the through slots. The position of the connecting plate can be finely adjusted by rotating the rotating rod.

[0013] Optionally, one side of one of the side plates has a through hole, and one end of the rotating rod is connected to a knob that is fixedly connected through the through hole.

[0014] Optionally, fixing pins are fixedly connected to the bottom of the connecting piece and the quick-release buckle, and several fixing pins pass through the inspection door and the fireproof protective cover panel respectively, with end caps snapped under the fixing pins.

[0015] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0016] By installing inspection doors on the fireproof protective cover panel and using four sets of snap-fit ​​components for detachable installation, the inspection doors can fit tightly against the fireproof protective cover panel when closed, forming a continuous protective surface. This not only effectively blocks the intrusion of external heat and smoke but also maintains the overall fireproof integrity of the cover. During daily operation or equipment maintenance, operators can open or close the inspection doors in seconds simply by operating the quick-opening mechanism, without the need for tools to remove or assemble screws, thus significantly reducing maintenance time and labor intensity.

Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings.

[0028] Please see Figure 1-5 As shown, this embodiment provides a quick-opening device for a fireproof protective cover inspection door, including a fireproof protective cover panel 1. An opening for maintenance operations is provided on one side of the fireproof protective cover panel 1, and an inspection door 2 is engaged at the opening.

[0029] The inspection door 2 and the fireproof protective cover panel 1 are detachably connected by four sets of snap-fit ​​components;

[0030] Each set of the snap-fit ​​assembly includes two quick-opening buckles 3 arranged at 90° to each other and fixedly installed on the side of the inspection door 2. A buckle seat 4 corresponding to the position of the quick-opening buckle 3 is also fixedly connected to one side of the inspection door 2. The quick-opening buckle 3 and the buckle seat 4 are interlocked.

[0031] A connecting piece 5 corresponding to the position of the fastener 4 is fixedly connected to one side of the fireproof protective cover panel 1. An adjustment mechanism is provided above the fastener 4 for adjusting the distance between the fastener 4 and the connecting piece 5. The fastener 4 is fixed to one side of the inspection door by bolts.

[0032] By installing an inspection door 2 on the fireproof protective cover panel 1 and using four sets of snap-fit ​​components for detachable connection, the inspection door 2 can fit tightly against the fireproof protective cover panel 1 when not in use, providing good protection and heat insulation. When maintenance is required, the operator can quickly open and close the door using the quick-opening buckle 3 structure, eliminating the tedious steps of traditional screw disassembly and assembly, and improving maintenance efficiency.

[0033] In this embodiment, the adjusting mechanism includes a connecting cylinder 6 fixedly installed above the buckle 4. Side plates 7 are fixedly connected to both sides of the connecting cylinder 6. The connecting piece 5 is slidably disposed inside the connecting cylinder 6 and located below the side plates 7.
