Description

Technical Field

[0001] This utility model relates to the field of gas heater support ring disassembly technology, specifically a disassembly and assembly device for a gas heater support ring. Background Technology

[0002] In the structure of a gas heater, the support ring is a key component used to connect and fix the outer and inner cylinders. Its installation stability directly affects the overall operational safety and service life of the heater. Traditional gas heater support rings often suffer from cumbersome operation and low efficiency during disassembly and assembly.

[0003] Currently, existing methods for disassembling and assembling support rings mostly rely on manual labor using common tools such as wrenches and screwdrivers. Since the support ring is typically fixed to the outer and inner cylinders using interference fits or multiple sets of bolts, disassembly requires loosening each connection individually. This is not only time-consuming and labor-intensive, but can also lead to wear and deformation of the support ring or cylinder surface due to uneven stress. Especially in confined spaces within the heater, tools are difficult to access, further increasing the difficulty of disassembly and assembly. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to provide a disassembly and assembly device for the support ring of a gas heater, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a disassembly and assembly device for a support ring of a gas heater, comprising an outer cylinder of a gas heater, an installation mechanism provided on the inner side of the outer cylinder of the gas heater, an inner cylinder of the gas heater provided on the inner side of the installation mechanism, and a disassembly mechanism provided on the inner side of the installation mechanism.

[0006] The disassembly mechanism includes a fixed cylinder, which is slidably connected to the inner side of the outer cylinder of the gas heater. A fixed plate is fixedly connected to the front of the fixed cylinder, and a pull plate is fixedly connected to the front of the fixed plate. A pressing plate is fixedly connected to the outer side of the back end of the fixed plate. A fixed plate is fixedly connected to the inner back end of the fixed cylinder. A first telescopic rod is fixedly connected to the inner side of the fixed plate. A pulling plate is fixedly connected to the outer side of the first telescopic rod. A first insert rod is fixedly connected to the outer side of the pulling plate. A first spring is sleeved around the first telescopic rod.

[0007] Preferably, the inner side of the fixed plate is provided with a groove corresponding to the position of the pull plate, and the pull plate is slidably connected inside the groove. Through the groove, the pull plate can slide inside the fixed plate, making the pull plate more stable during movement.

[0008] Preferably, the outer side of the first spring is fixedly connected to the inner side of the pull plate, and the inner side of the first spring is fixedly connected to the inner side of the fixed plate. When the first insert rod is squeezed by the support ring body, the first insert rod can squeeze the first telescopic rod and the first spring through the pull plate.

[0009] Preferably, the installation mechanism includes a support ring body, which is disposed inside the outer cylinder of the gas heater. A second telescopic rod is fixedly connected to the inner side of the support ring, a hollow plate is fixedly connected to the outer side of the second telescopic rod, a sliding plate is fixedly connected to the outer side of the hollow plate, a second insert rod is fixedly connected to the outer side of the sliding plate, and a second spring is sleeved around the second telescopic rod.

[0010] Preferably, the outer side of the second spring is fixedly connected to the inner side of the hollow plate, and the inner side of the second spring is fixedly connected to the inner side of the support ring body. Through the elastic force of the second spring, the second telescopic rod drives the sliding plate and the second insert rod to move through the hollow plate, so that the second insert rod can be inserted into the inner side of the outer cylinder of the gas heater to limit the support ring body.

[0011] Preferably, the inner side of the outer cylinder of the gas heater has a hole corresponding to the position of the second insertion rod, and the second insertion rod is inserted into the inner side of the hole. Through the hole, the second insertion rod can be inserted into the inner side of the outer cylinder of the gas heater to limit the installation of the support ring body.

[0012] Preferably, the hollow plate has an inclined groove on its inner side, and the inner side of the extrusion plate is in contact with the inner side of the hollow plate. Through the inclined groove, the extrusion plate can be inserted into the hollow plate to extrude the hollow plate.

[0013] Compared with the prior art, the present invention provides a disassembly and assembly device for the support ring of a gas heater, which has the following advantages:

[0014] 1. The support ring of the gas heater is disassembled and assembled using a disassembly device. In the disassembly mechanism, the operator manually pushes the pull plate, which moves the fixed plate, the extrusion plate, and the fixed cylinder, so that the first insert rod is squeezed by the support ring body, which pushes the pull plate to squeeze the first telescopic rod and the first spring. When the first insert rod is no longer squeezed, it resets under the action of the first spring, and continues to push the fixed plate. The extrusion plate squeezes the hollow plate, so that the hollow plate drives the second insert rod away from the outer cylinder of the gas heater through the sliding plate, thereby realizing the rapid disassembly of the support ring body.

[0015] 2. The gas heater's support ring uses a disassembly and assembly device. In the installation mechanism, when installing the support ring body, it is moved to the inside of the gas heater's outer cylinder. The second insertion rod is squeezed by the outer cylinder, and pushes the hollow plate and the first telescopic rod through the sliding plate, squeezing the second spring. When the support ring body slides inside until the second insertion rod is no longer obstructed, the second spring rebounds, causing the second telescopic rod, the hollow plate, and the sliding plate to reset, so that the second insertion rod is inserted into the outer cylinder to complete the installation.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] This utility model provides the following technical solution:

[0026] Example 1

[0027] Please see Figure 1-5 This utility model provides a technical solution: a disassembly and assembly device for a support ring of a gas heater, including a gas heater outer cylinder 1, an installation mechanism 4 provided inside the gas heater outer cylinder 1, a gas heater inner cylinder 2 provided inside the installation mechanism 4, and a disassembly mechanism 3 provided inside the installation mechanism 4.

[0028] The disassembly mechanism 3 includes a fixed cylinder 34, which is slidably connected to the inner side of the outer cylinder 1 of the gas heater. A fixed plate 32 is fixedly connected to the front of the fixed cylinder 34, and a pull plate 33 is fixedly connected to the front of the fixed plate 32. A pressing plate 31 is fixedly connected to the outer side of the back end of the fixed plate 32. A fixed plate 36 is fixedly connected to the back end of the inner side of the fixed cylinder 34. A first telescopic rod 37 is fixedly connected to the inner side of the fixed plate 36. A pulling plate 39 is fixedly connected to the outer side of the first telescopic rod 37. A first insert rod 35 is fixedly connected to the outer side of the pulling plate 39. A first spring 38 is sleeved around the first telescopic rod 37.

[0029] Furthermore, a groove corresponding to the position of the pull plate 39 is provided on the inner side of the fixed plate 36, and the pull plate 39 is slidably connected to the inside of the groove. Through the groove, the pull plate 39 can slide inside the fixed plate 36, making the pull plate 39 more stable during movement.

[0030] Furthermore, the outer side of the first spring 38 is fixedly connected to the inner side of the pull plate 39, and the inner side of the first spring 38 is fixedly connected to the inner side of the fixing plate 36. When the first insert rod 35 is squeezed by the support ring body 41, the first insert rod 35 can squeeze the first telescopic rod 37 and the first spring 38 through the pull plate 39.

[0031] Example 2

[0032] Please see Figure 1-5Furthermore, based on Embodiment 1, the installation mechanism 4 includes a support ring body 41, which is disposed inside the outer cylinder 1 of the gas heater. A second telescopic rod 44 is fixedly connected to the inner side of the support ring, a hollow plate 46 is fixedly connected to the outer side of the second telescopic rod 44, a sliding plate 43 is fixedly connected to the outer side of the hollow plate 46, a second insert rod 42 is fixedly connected to the outer side of the sliding plate 43, and a second spring 45 is sleeved around the second telescopic rod 44.

[0033] Furthermore, the outer side of the second spring 45 is fixedly connected to the inner side of the hollow plate 46, and the inner side of the second spring 45 is fixedly connected to the inner side of the support ring body 41. Through the elastic force of the second spring 45, the second telescopic rod 44 drives the sliding plate 43 and the second insertion rod 42 to move through the hollow plate 46, so that the second insertion rod 42 can be inserted into the inner side of the outer cylinder 1 of the gas heater to limit the support ring body 41.

[0034] Furthermore, an insertion hole corresponding to the position of the second insertion rod 42 is opened on the inner side of the outer cylinder 1 of the gas heater, and the second insertion rod 42 is inserted into the inner side of the insertion hole. Through the opening of the insertion hole, the second insertion rod 42 can be inserted into the inner side of the outer cylinder 1 of the gas heater to limit the installation of the support ring body 41.

[0035] Furthermore, an inclined groove is provided on the inner side of the hollow plate 46, and the inner side of the extrusion plate 31 is in contact with the inner side of the hollow plate 46. Through the inclined groove, the extrusion plate 31 can be inserted into the hollow plate 46 to extrude the hollow plate 46.

[0036] In actual operation, when this device is used and it is necessary to install the support ring body 41, the support ring body 41 is moved to the inside of the outer cylinder 1 of the gas heater, so that the second insertion rod 42 is squeezed by the outer cylinder 1 of the gas heater. The second insertion rod 42 pushes the hollow plate 46 and the first telescopic rod 37 to move through the sliding plate 43, so that the sliding plate 43 squeezes the second spring 45. When the support ring body 41 slides inside the outer cylinder 1 of the gas heater, the second insertion rod 42 is not blocked by the outer cylinder 1 of the gas heater. Through the elastic force of the second spring 45, the second spring 45 drives the second telescopic rod 44 and the hollow plate 46 to move, so that the hollow plate 46 can drive the second insertion rod 42 to move through the sliding plate 43, so that the second insertion rod 42 can be inserted into the inside of the outer cylinder 1 of the gas heater to install the support ring body 41.

[0037] When the support ring body 41 needs to be disassembled, the worker manually supports the pull plate 33, causing the pull plate 33 to push the fixed plate 32, which in turn moves the compression plate 31 and the fixed cylinder 34. This allows the fixed cylinder 34 to move the first insertion rod 35, causing the first insertion rod 35 to be compressed by the support ring body 41. The first insertion rod 35 then pushes the pull plate 39 to compress the first telescopic rod 37 and the first spring 38. When the first insertion rod 35 is no longer compressed by the support ring body 41, the elastic force of the first spring 38 causes the first insertion rod 35 to return to its original position and continue to push the fixed plate 32 inward. The fixed plate 32 then drives the compression plate 31 to compress the hollow plate 46. The pressure causes the hollow plate 46 to move the second insertion rod 42 via the sliding plate 43, moving the second insertion rod 42 away from the inside of the outer cylinder 1 of the gas heater. The operator manually rotates the pull plate 33, which drives the extrusion plate 31 and the fixed cylinder 34 to rotate via the fixed plate 32, moving the first insertion rod 35 away from the insertion hole on the inner side of the outer cylinder 1 of the gas heater. The front of the first insertion rod 35 is in contact with the back end of the support ring body 41. The operator manually pulls the pull plate 33, which drives the first insertion rod 35 to move via the fixed cylinder 34, causing the first insertion rod 35 to move the support ring body 41, allowing the support ring body 41 to be quickly disassembled by the operator.
