Description

Technical Field

[0001] This utility model relates to the field of sealing device technology, and in particular to a sealing device. Background Technology

[0002] Mining hole sealers are safety devices used in coal mines and other mines. They are mainly used to seal or block holes or passages in the mine to prevent the leakage of harmful gases, the occurrence of fires, or the intrusion of water. Hole sealers can effectively prevent external factors from affecting mine operations and ensure the safety of miners.

[0003] In practical use, existing sealing devices are generally inserted directly into the corresponding holes. Since the rubber plug at the bottom of the sealing device is not inflated when it first enters the hole, the sealing device cannot be centered in the hole. As a result, when the rubber plug expands later, some contact surfaces will be subjected to greater pressure, which can easily cause local wear on the rubber plug. This is not conducive to maintaining the tight sealing performance of the device for long-term use. In addition, when the operator judges the insertion depth of the sealing device, a measuring tape needs to be attached to the side of the device and inserted into the hole for observation. The overall operation process is cumbersome and lacks flexibility. Utility Model Content

[0004] The purpose of this utility model is to provide a sealing device to solve the problems mentioned in the background art. In actual use, existing sealing devices are generally directly inserted into the corresponding hole. Since the rubber plug at the bottom of the sealing device is in an unexpanded state when it is initially inserted into the hole, the sealing device cannot be centered in the hole. In this state, when the rubber plug expands later, some contact surfaces will be subjected to greater pressure, which will easily cause local wear of the rubber plug. This is not conducive to maintaining the tight sealing performance of the device for long-term use. At the same time, when the operator judges the insertion depth of the sealing device, a measuring tape needs to be attached to the side of the device and inserted into the hole for observation. The overall operation process is cumbersome and lacks flexibility.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a sealing device, comprising:

[0007] The sealing device body;

[0008] The support cylinder and rotating handle are installed inside the sealing device body;

[0009] A depth indicating mechanism, comprising a support plate and a length scale, wherein the support plate is provided on the outer side wall of the support cylinder, and a placement groove is provided on the outer side wall of the support plate, and a length scale is embedded in the placement groove.

[0010] Furthermore, the larger reading end of the length scale is located near the rotating handle.

[0011] Furthermore, it also includes a centering positioning mechanism, which includes a support ring, a limiting cylinder, a limiting piston rod, a support spring, and a contact plate. The supporting cylinder has a support ring on its outer side wall, and the limiting cylinder is embedded around the outer side wall of the support ring at equal intervals. The limiting piston rod is slidably installed inside the limiting cylinder. A support spring is connected between the limiting piston rod and the bottom inner wall of the limiting cylinder. The protruding end of the limiting piston rod is located outside the limiting cylinder, and the protruding end of the limiting piston rod is connected to the outer side wall of the contact plate.

[0012] Furthermore, the limiting cylinder is filled with damping fluid, and the side outer wall of the limiting piston rod located at the piston disc position is provided with through holes at equal intervals for overflowing the damping fluid.

[0013] Furthermore, the overall structure of the contact plate is set as an arc-shaped structure, and the outer walls on both sides of the contact plate are also set as arc-shaped structures.

[0014] Furthermore, it also includes a gripping and protective mechanism, which includes an auxiliary mounting cylinder and an annular elastic pad. The auxiliary mounting cylinder is sleeved on the outside of the handle at the rotating handle position, and an annular elastic pad is provided on the outer side wall of the auxiliary mounting cylinder away from the rotating handle position.

[0015] Furthermore, one side of the outer wall of the auxiliary mounting cylinder is configured as an open structure, and the other side of the outer wall of the auxiliary mounting cylinder is provided with a first threaded groove. The outer wall of the handle of the rotating handle is provided with a corresponding second threaded groove. The first threaded groove and the second threaded groove are threadedly installed with the fastening bolt.

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] This invention features a design that uses a spring support assembly on the side to centrally support the sealing device. This ensures that the sealing device remains centered and stable when inserted into the hole. Furthermore, by maintaining the centered position of the sealing device, the contact distance between the rubber stopper and the inner wall of the hole is similar when the rubber stopper expands. This prevents excessive distance from causing greater local pressure on the rubber stopper, thus ensuring the safe use of the rubber stopper and reducing the risk of localized damage.

[0018] Furthermore, by incorporating an embedded length scale on the side of the device, operators can directly observe the reading on the length scale to determine the insertion depth of the sealing device, eliminating the need for an additional measuring tape. Additionally, the annular elastic pad on the outside of the rotating handle prevents slippage during operation, enhancing comfort. Furthermore, the removable design of the annular elastic pad facilitates easy replacement and maintenance. The overall structure is ingeniously designed and highly practical.

[0033] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0034] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0036] Please see Figure 1-6 As shown, this embodiment is a sealing device, comprising:

[0037] Sealing device body 1;

[0038] The support cylinder 2 and the rotating handle 3 are installed inside the sealing device body 1;

[0039] The support cylinder 2 and the rotating handle 3 are components integrated into the sealing device body 1. Therefore, only the component names are briefly introduced here. For specific installation locations and structural components, please refer to the instruction manual. Figure 1 This is a current technological method, so it has not been described in detail.

[0040] The depth indicating mechanism 4 includes a support plate 41 and a length scale 42. The support plate 41 is provided on the outer side wall of the support cylinder 2. A placement groove is provided on the outer side wall of the support plate 41, and the length scale 42 is embedded in the placement groove.

[0041] The larger reading end of the length scale 42 is closer to the rotating handle 3;

[0042] This setup allows staff to directly observe the insertion depth of the device when reading the length scale 42, eliminating the need for secondary calculations based on the data indicated by the length scale 42.

[0043] In terms of working principle, the support plate 41 is set here to facilitate the installation of the length scale 42. The length scale 42 allows the operator to directly know the insertion depth of the sealing device body 1 by observing the length indicator data above the length scale 42 when inserting the sealing device body 1 into the hole, without the need to use a tape measure for secondary measurement.

[0044] The centering positioning mechanism 5 includes a support ring 51, a limiting cylinder 52, a limiting piston rod 53, a support spring 54, and a contact plate 55. The support cylinder 2 has a support ring 51 on its outer side wall. The limiting cylinder 52 is embedded around the outer side wall of the support ring 51 at equal intervals. The limiting piston rod 53 is slidably installed inside the limiting cylinder 52. The support spring 54 is connected between the limiting piston rod 53 and the bottom inner wall of the limiting cylinder 52. The protruding end of the limiting piston rod 53 is located outside the limiting cylinder 52, and the protruding end of the limiting piston rod 53 is connected to the outer side wall of the contact plate 55.

[0045] The limiting cylinder 52 is filled with damping fluid, and the limiting piston rod 53 has through holes for overflowing damping fluid in an evenly spaced manner on the outer side wall of the piston plate.

[0046] The damping fluid here allows the limiting piston rod 53 to move more smoothly under the influence of the damping fluid pressure when sliding inside the limiting cylinder 52, while the through hole facilitates the movement of the damping fluid back and forth inside the limiting cylinder 52.

[0047] The overall structure of the contact plate 55 is set as an arc-shaped structure, and the outer walls on both sides of the contact plate 55 are also set as arc-shaped structures;

[0048] The overall structure of the contact plate 55 is set as an arc shape so that its shape can better fit the inner wall of the hole, thereby facilitating better support for the inner wall of the hole. The outer walls on both sides of the contact plate 55 are set as arc shapes so that the resistance encountered when it is inserted into the hole is reduced, thus ensuring that the insertion process of the entire device is not affected.

[0049] Working principle: When the sealing device body 1 is pushed into the hole by manual force, the contact plate 55 enters the hole and automatically retracts towards the sealing device body 1 under the pressure of the hole wall. The movement of the contact plate 55 then automatically drives the limiting piston rod 53 to slide inside the limiting cylinder 52. As the limiting piston rod 53 moves, it automatically compresses the damping fluid inside the limiting cylinder 52, causing the damping fluid to move from one side of the limiting piston rod 53 to the other through the through hole. This process controls the movement of the limiting piston rod 53. The movement provides a buffering and protective effect. When the limiting piston rod 53 moves, it also simultaneously compresses the support spring 54, causing the support spring 54 to retract. Once the sealing device body 1 has moved to the appropriate depth, the operator stops pushing the sealing device body 1. The reaction force generated by the support spring 54, without any interference from the operator, automatically pushes the limiting piston rod 53 in the opposite direction. When the limiting piston rod 53 moves, it automatically pushes the contact plate 55 to move and make it fit against the inner wall of the hole. (Refer to the attached instruction manual.) Figure 3 As shown, the simultaneous support of multiple sets of abutment plates 55 can center the sealing device body 1 at the center of the hole.

[0050] The gripping and protective mechanism 6 includes an auxiliary mounting cylinder 61 and an annular elastic pad 62. The auxiliary mounting cylinder 61 is sleeved on the outside of the handle at the position of rotating handle 3. The annular elastic pad 62 is provided on the outer side wall of the auxiliary mounting cylinder 61 away from the position of rotating handle 3.

[0051] The auxiliary mounting cylinder 61 here serves to position and install the annular elastic pad 62.

[0052] One side of the outer wall of the auxiliary mounting cylinder 61 is set as an open structure, and the other side of the outer wall of the auxiliary mounting cylinder 61 is provided with a first threaded groove 63. The outer wall of the handle of the rotating handle 3 is provided with a second threaded groove 64. The first threaded groove 63 and the second threaded groove 64 are threadedly installed with the fastening bolt 65.

[0053] The combination of the first threaded groove 63, the second threaded groove 64, and the fastening bolt 65 here makes the auxiliary mounting cylinder 61 detachable, thereby facilitating the replacement process of the annular elastic pad 62.

[0054] Working principle: The annular elastic pad 62 makes the operation of the rotating handle 3 more comfortable for the operator. The annular elastic pad 62 also increases the stability of the operator's hand gripping the rotating handle 3, making it less likely to slip when operating the equipment. When the annular elastic pad 62 becomes worn and damaged due to accumulated use, simply unscrew the fastening bolt 65 completely from the inside of the first threaded groove 63, thereby changing the auxiliary mounting cylinder 61 from the locked state to the movable state. Then, simply remove it along with the annular elastic pad 62 from the side of the rotating handle 3. When replacing the annular elastic pad 62, first adjust the auxiliary mounting cylinder 61 to the appropriate position and put it on the outside of the handle of the rotating handle 3. Then, use the fastening bolt 65 to pass through the first threaded groove 63 and screw it to the bottom of the second threaded groove 64 to complete the replacement and installation of the annular elastic pad 62.

[0055] It should be noted that the operation and use of the above-mentioned sealing device body 1 should be carried out in accordance with the existing technical requirements and specifications. It is a conventional operating technique and will not be described in detail here.
