Description

Technical Field

[0001] This utility model relates to the technical field of tunnel portal sealing devices, and in particular to a simple tunnel portal sealing device. Background Technology

[0002] A tunnel portal sealing device is a facility used at the entrance of a tunnel to achieve functions such as sealing and protection. Simple tunnel portal sealing devices have a simple structure, are easy to troubleshoot and repair when problems occur, and are convenient to operate during use.

[0003] Existing tunnel portal sealing devices typically employ an inflatable sealing structure. During sealing, air is inflated into the airbag to achieve the sealing effect. However, this process requires inflating and deflating the airbag, which is time-consuming and inconvenient.

[0004] Therefore, those skilled in the art have provided a simple tunnel portal sealing device to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a simple tunnel entrance sealing device that effectively facilitates the sealing of tunnels and enhances the sealing effect.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A simple tunnel portal sealing device includes a tunnel portal body, a locking mechanism fixedly disposed in the middle of the surface of the tunnel portal body, and first sliding grooves opened on both sides of the surface of the tunnel portal body, with a fixing mechanism slidably connected inside the two first sliding grooves;

[0008] The locking mechanism includes a guide rail, a second sliding groove is provided on one side of the guide rail, a first moving plate is slidably connected to one side surface of the guide rail, and a second moving plate is slidably connected to the other side surface of the guide rail. The fixing mechanism includes a first sliding plate, and a concave fixing plate is fixedly provided on one side of the first sliding plate.

[0009] Furthermore, a handle is fixedly provided on the upper surface of the tunnel door body, and connecting shafts are hinged on both sides of the tunnel door body.

[0010] Furthermore, a spring pin is fixedly provided on one side of the first movable plate, and a second baffle is fixedly provided on one side of the bottom end of the first movable plate.

[0011] Furthermore, a fixed plug is fixedly provided on one side of the second movable plate, and a first baffle is fixedly provided on one side of the bottom end of the second movable plate.

[0012] Furthermore, a second fixing piece is fixedly provided at the bottom end of the first sliding plate, and a third sliding groove is provided on the other side of the first sliding plate.

[0013] Furthermore, a second sliding plate is slidably connected to the surface of the third sliding groove, and a rotating rod is fixedly provided at one end of the second sliding plate.

[0014] Furthermore, a fixing frame is fixedly provided on the surface of the multiple connecting shafts, and a multiple first fixing pieces are fixedly provided at the bottom end of the fixing frame.

[0015] This utility model has the following beneficial effects:

[0016] 1. The present invention proposes a simple tunnel door sealing device, which is equipped with a locking mechanism. When the tunnel door is closed, by moving the first and second moving plates of the locking mechanism, the fixed plug on one side of the second moving plate is moved into the spring pin on the side of the first moving plate. At this time, due to the obstruction of the spring pin, the first and second moving plates can no longer move, thus locking the tunnel door body. This effectively seals the tunnel door and enhances the sealing effect of the tunnel door.

[0017] 2. The present invention proposes a simple tunnel portal sealing device, which is equipped with a fixing mechanism. When the locking mechanism moves, the fixing mechanism loses the support of the locking mechanism, and the first sliding plate slides downward until the second fixing plate moves to the ground. The first sliding plate stops moving and is fixed by inserting screws. At this time, the tunnel portal body is reinforced and fixed, which makes the portal sealing ability better and effectively enhances the sealing performance of the tunnel portal.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figure 1 One embodiment provided by this utility model:

[0028] A simple tunnel portal sealing device includes a tunnel portal body 1, a locking mechanism 6 fixedly installed in the middle of the surface of the tunnel portal body 1, first sliding grooves 7 opened on both sides of the surface of the tunnel portal body 1, a fixing mechanism 8 slidably connected inside the two first sliding grooves 7, a handle 5 fixedly installed at the upper end of the surface of the tunnel portal body 1, connecting shafts 2 hinged on both sides of the tunnel portal body 1, fixing frames 3 fixedly installed on the surface of multiple connecting shafts 2, and multiple first fixing pieces 4 fixedly installed at the bottom of the fixing frames 3;

[0029] Specifically, the locking mechanism 6 and the fixing mechanism 8 are used for locking and fixing, and the first fixing piece 4 is used to fix the fixing frame 3 in the tunnel.

[0030] Reference Figure 2 - Figure 5 The locking mechanism 6 includes a guide rail 601, a second sliding groove 602 on one side of the guide rail 601, a first moving plate 603 slidably connected to one side surface of the guide rail 601, a second moving plate 604 slidably connected to the other side surface of the guide rail 601, a spring pin 605 fixedly provided on one side of the first moving plate 603, a second baffle 608 fixedly provided on one side of the bottom end of the first moving plate 603, a fixed plug 607 fixedly provided on one side of the second moving plate 604, and a first baffle 606 fixedly provided on one side of the bottom end of the second moving plate 604.

[0031] Specifically, the guide rail 601 is used to facilitate the movement of the first moving plate 603 and the second moving plate 604. One end 607 of the second moving plate 604 is inserted into the spring pin 605 for fixation. The first baffle 606 and the second baffle 608 are used to limit the range of movement on the guide rail 601.

[0032] Reference Figure 6 The fixing mechanism 8 includes a first sliding plate 801, a concave fixing plate 804 fixedly disposed on one side of the first sliding plate 801, a second fixing piece 806 fixedly disposed at the bottom end of the first sliding plate 801, a third sliding groove 805 opened on the other side of the first sliding plate 801, a second sliding plate 803 slidably connected to the surface of the third sliding groove 805, and a rotating rod 802 fixedly disposed at one end of the second sliding plate 803;

[0033] Specifically, the concave fixing plate 804 is used to facilitate the insertion of the first moving plate 603 and the second moving plate 604 for support, the second fixing piece 806 is used to insert screws for fixing after the bottom of the first sliding plate 801 lands, and the third sliding groove 805 is used to facilitate the movement of the second sliding plate 803.

[0034] Working principle: First, move the device into the tunnel. Then, use screws to fix the first fixing plate 3. Then close the tunnel door body 1. Move the fixing plug 607 on one side of the second moving plate 604 into the spring pin 605 on the side of the first moving plate 603. At this time, due to the obstruction of the spring pin 605, the first moving plate 603 and the second moving plate 604 can no longer move.

[0035] Secondly, when the fixing mechanism 8 loses the support of the locking mechanism 6, the first sliding plate 801 will slide downward until the second fixing plate 806 moves to the ground. At this time, the first sliding plate 801 stops moving and is fixed by inserting screws into the second fixing plate 806.
