Description

Technical Field

[0001] This utility model relates to the field of tobacco storage technology, and in particular to a fixed mechanism for a hand-operated air vent pull cord. Fixed device. Background Technology

[0002] After tobacco processing, it needs to be stored to prevent it from being affected by external factors and spoiling. Because tobacco is very sensitive to humidity, excessive humidity can cause the tobacco leaves to mold, affecting their flavor and quality, while excessively low humidity can cause the tobacco to dry out. Therefore, tobacco storage warehouses are usually equipped with air windows for ventilation, which helps to keep the air fresh and remove moisture and odors.

[0003] Currently, most tobacco storage warehouses use manual ventilation windows. On the one hand, manual ventilation windows have a simple structure and are easy to operate. They can be opened quickly to allow air circulation, helping the warehouse to keep the air fresh and remove moisture and odors. Especially in humid environments, poor ventilation can easily lead to mold growth on goods. The manual design can quickly respond to ventilation needs. On the other hand, tobacco storage warehouses are flammable storage sites and must strictly comply with fire safety regulations. Manually operated ventilation windows can be opened quickly in the event of a fire, working in conjunction with the natural smoke exhaust system to expel smoke, creating conditions for personnel evacuation and fire rescue. In addition, the manual opening method avoids the problem of power dependence of electric equipment in emergency situations.

[0004] In existing tobacco storage warehouses, the pull cord for the manual air vents is typically fixed to a downward-facing J-hook after the vent is closed. However, this fixing method has the problem of the pull cord not being securely fixed, making it easy for the manual air vents to open without human intervention. For example, in strong winds or heavy rain, they may be blown open, causing the tobacco stored in the warehouse to get wet and resulting in serious losses. Utility Model Content

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0021] Please see Figures 1-4 This utility model discloses a fixing device for a hand-operated window pull cord, comprising a mounting base 1 and a fixing base 2 arranged in parallel at intervals, and a rope winding post 3 disposed between the mounting base 1 and the fixing base 2. The two ends of the rope winding post 3 are fixedly connected to the mounting base 1 and the fixing base 2, respectively. The mounting base 1 is fixedly installed on the wall, the rope winding post 3 is used to wind the pull cord, and the fixing base 2 is provided with a rope winding groove 21. The pull cord wound on the rope winding post 3 passes through the rope winding groove 21 to fix the pull cord.

[0022] In this application, the fixing device includes a mounting base 1, a fixing base 2, and a rope winding post 3. The mounting base 1 and the fixing base 2 are arranged parallel to each other and spaced apart. The rope winding post 3 is arranged between the mounting base 1 and the fixing base 2, and both ends of the rope winding post 3 are fixedly connected to the mounting base 1 and the fixing base 2 respectively, thereby connecting the mounting base 1 and the fixing base 2 through the rope winding post 3.

[0023] The mounting base 1 is fixedly connected to the wall, thus fixing the mounting base 1 to the wall and achieving the installation of this fixing device on the wall. The fixing base 2 is provided with a rope winding groove 21. When fixing the pull rope of the manual air vent, first wrap the vertical pull rope around the rope winding post 3, and then let the pull rope pass through the rope winding groove 21 to fix the pull rope, so as to prevent the manual air vent from being opened without human intervention, which would affect the quality of tobacco storage.

[0024] In this embodiment, a screw 4 is installed at a designated position on the wall according to the length of the pull rope. The mounting base 1 has a through hole 11, through which one end of the screw 4 passes. The fixing device also includes a fixing nut 5, which is screwed to the end of the screw 4 that passes through the through hole 11, thereby fixing the mounting base 1 on the wall and realizing the installation of this fixing device on the wall.

[0025] In this embodiment, two rope-winding posts 3 are provided between the mounting base 1 and the fixing base 2. The two rope-winding posts 3 are arranged in parallel and spaced apart, and both ends of the two rope-winding posts 3 are fixedly connected to the mounting base 1 and the fixing base 2, respectively. When fixing the pull rope, the pull rope is wound around the two rope-winding posts 3, and then the pull rope is passed through the rope-winding groove 21 on the fixing base 2, so that the fixing base 2 fixes the pull rope, thereby making the fixation of the pull rope more stable and enhancing the structural strength of this fixing device.

[0026] In this embodiment, the rope winding groove 21 includes a top groove 211 and a bottom groove 212. The top groove 211 is located at the top of the fixing base 2, and the bottom groove 212 is located at the bottom of the fixing base 2. When fixing the pull rope, the pull rope is wound around the rope winding post 3, and then pulled from the rear side of the fixing base 2 to the top of the fixing base 2, so that it passes through the top groove 211. Then, the pull rope is pulled from the front side of the fixing base 2 to the bottom of the fixing base 2, so that it passes through the bottom groove 212, thereby winding the pull rope around the fixing base 2. The top groove 211 and the bottom groove 212 limit the pull rope, thereby preventing the manual air vent from opening without human intervention, which would affect the quality of tobacco storage.

[0027] Manually operated air vents typically have two vertical pull cords (actually a single loop). Pulling one cord opens the air vent, while pulling the other cord closes it. Therefore, in this embodiment, the top of the mounting base 2 has two top grooves 211, spaced apart. The bottom of the mounting base 2 has two bottom grooves 212, also spaced apart.

[0028] When fixing the pull rope, one of the pull ropes is wound around the rope winding post 3 and then pulled from the back of the fixing seat 2 to the top of the fixing seat 2 so that it passes through a top groove 211. Then the pull rope is pulled from the front of the fixing seat 2 to the bottom of the fixing seat 2 so that it passes through a bottom groove 212, thereby fixing the pull rope on the fixing seat 2.

[0029] After the other pull rope is wound around the rope-winding post 3, it is pulled from the rear side of the fixing seat 2 to the top of the fixing seat 2, so that it passes through another top groove 211. Then the pull rope is pulled from the front side of the fixing seat 2 to the bottom of the fixing seat 2, so that it passes through another bottom groove 212, thereby fixing the pull rope on the fixing seat 2, and thus fixing the two pull ropes to prevent the manual air window from being opened without human intervention, which would affect the quality of tobacco storage.

[0030] In this embodiment, when fixing the two pull ropes, one of the pull ropes is wound around the rope winding post 3, then wound from the rear side of the fixing seat 2 to the top front side of the fixing seat 2, so that it passes through a top groove 211 far away, and then wound to the bottom rear side of the fixing seat 2, so that it passes through a bottom groove 212 far away, thereby winding the pull rope around the fixing seat 2 and fixing the pull rope.

[0031] After the other pull rope is wound around the rope-winding post 3, it is wound from the back of the fixing seat 2 to the top of the front of the fixing seat 2, so that it passes through another top groove 211 far away. Then the pull rope is wound to the bottom of the back of the fixing seat 2, so that it passes through another bottom groove 212 far away. In this way, the two pull ropes are cross-wound around the fixing seat 2, making the two pull ropes more securely fixed on the fixing seat 2, and further preventing the manual air window from being opened without human intervention, which would affect the quality of tobacco storage.

[0032] In this embodiment, the fixing device further includes a cord fastening assembly 6, which is disposed on the front side of the fixing base 2 and forms a cord fastening hole 7 between the cord fastening assembly 6 and the fixing base 2. One end of the cord fastening assembly 6 is rotatably connected to the fixing base 2, and the other end can be fastened to the fixing base 2, thereby closing the cord fastening hole 7 when the cord fastening assembly 6 is fastened to the fixing base 2.

[0033] Since the two pull ropes are intertwined on the fixing seat 2, they pass through the buckle hole 7 and are pressed onto the fixing seat 2 by the buckle assembly 6, making the two pull ropes more securely fixed on the fixing seat 2 and further preventing the manual air vent from being opened without human intervention, thus affecting the quality of tobacco storage.

[0034] When it is necessary to open or close the manual air vent by pulling the pull cord, the end of the cord fastener assembly 6 that is fastened to the fixing base 2 is disengaged from the fixing base 2, so that the cord fastener assembly 6 can rotate on the fixing base 2, thereby opening the cord fastening hole 7. This allows the two pull cords wrapped around the fixing base 2 and the cord winding post 3 to be unwound from the fixing base 2 and the cord winding post 3, and then the manual air vent can be opened or closed by pulling the two pull cords.

[0035] Specifically, in this embodiment, the cord fastening assembly 6 includes a cord fastening plate 61, which is located on the front side of the fixing base 2, with one end rotatably connected to the fixing base 2 and the other end capable of being fastened to the fixing base 2. In this application, the cord fastening plate 61 is U-shaped, and a cord fastening hole 7 is formed between the cord fastening plate 61 and the front side of the fixing base 2.

[0036] When the buckle plate 61 rotates on the fixed base 2 until the other end of the buckle plate 61 is fastened to the fixed base 2, the buckle hole 7 is closed. At this time, the two pull ropes that are crossed and wrapped on the fixed base 2 pass through the buckle hole 7, so that the buckle plate 61 presses the two pull ropes onto the fixed base 2, making the two pull ropes more securely fixed on the fixed base 2, and further preventing the manual air window from being opened without human intervention, which would affect the quality of tobacco storage.

[0037] When it is necessary to open or close the manual air vent, disengage the end of the buckle plate 61 that is fastened to the fixed base 2 from the fixed base 2, so that the buckle plate 61 rotates on the fixed base 2, opening the buckle hole 7. This allows the two pull ropes wrapped around the fixed base 2 and the rope winding post 3 to be unwound from the fixed base 2 and the rope winding post 3. Then, by pulling the two pull ropes, the manual air vent can be opened or closed.

[0038] Specifically, in this embodiment, the top of the fixed base 2 is provided with a rotating groove 22, and the rotating groove 22 is located between the two top grooves 211 on the top of the fixed base 2. The opposite side walls of the rotating groove 22 are provided with rotating holes 221, and both sides of one end of the buckle plate 61 are provided with rotating shafts 62. The two rotating shafts 62 are respectively rotated and engaged with the rotating holes 221, thereby realizing the rotatable connection between one end of the buckle plate 61 and the fixed base 2.

[0039] Specifically, in this embodiment, the bottom of the fixing base 2 is provided with a locking groove 23, and the locking groove 23 is located between the two bottom grooves 212 at the bottom of the fixing base 2. The other end of the buckle plate 61 is provided with a buckle 63. By engaging the buckle 63 with the locking groove 23, the other end of the buckle plate 61 is fastened to the fixing base 2.

[0040] When the buckle plate 61 rotates around the rotating shaft 62 on the fixed base 2 until the buckle 63 at the other end of the buckle plate 61 is engaged with the locking groove 23 at the bottom of the fixed base 2, the buckle hole 7 between the buckle plate 61 and the outer side of the fixed base 2 is closed. This allows the buckle plate 61 to press the two pull ropes passing through the buckle hole 7 onto the fixed base 2, making the two pull ropes more securely fixed on the fixed base 2. This further prevents the manual air vent from being opened without human intervention, which would affect the quality of tobacco storage.

[0041] When it is necessary to open or close the manual air vent, the buckle 63 at the other end of the buckle plate 61 is disengaged from the locking groove 23 at the bottom of the fixing seat 2. Then, the buckle plate 61 is rotated in the opposite direction around the rotating shaft 62 on the fixing seat 2, thereby opening the buckle hole 7. This allows the two pull ropes wrapped around the fixing seat 2 and the rope winding post 3 to be unwound from the fixing seat 2 and the rope winding post 3. Then, by pulling the two pull ropes, the manual air vent can be opened or closed.

[0042] The above-described contents can be implemented individually or in combination in various ways, and all such variations are within the protection scope of this utility model.
