DETAILED DESCRIPTION

[0033] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments:

[0034] See also Figures 1 to 6, an adjustable hinge that is easy to disassemble and assemble, includes a hinge body 100, which includes a U-shaped base 10, a rotating connector 20, two furnace body connecting plates 30, two furnace cover connecting plates 40, a pressure rod assembly 50, at least one spring assembly 60, and a sleeve assembly 70 installed when the spring assembly 60 is disassembled and assembled. The number of the sleeve assembly 70 can be only one, and multiple spring assemblies 60 share one sleeve assembly 70, or each spring assembly 60 can be equipped with a sleeve assembly 70. The rotating connector 20 is rotatably connected to the U-shaped base 10. For example, the rotating connector 20 and the U-shaped base 10 are rotatably connected by fastening connectors 22 such as bolts and nuts. The two furnace body connecting plates 30 are respectively fixed to the two first side plates 11 of the U-shaped base 10, and the furnace body connecting plates 30 are also fixedly connected to the furnace body. The two furnace cover connecting plates 40 are respectively fixed to the two second side plates 21 of the rotating connector 20, and the furnace cover connecting plates 40 are also fixedly connected to the furnace cover. Both ends of the pressure rod assembly 50 are fixedly connected to the rotating connector 20. The spring assembly 60 is arranged in the cavity of the U-shaped base 10. In the present embodiment, the number of the spring assemblies 60 is two. The spring assembly 60 comprises a spring shaft 61 and an upper limit member 62, a spring 63 and a lower limit member 64 which are sleeved on the spring shaft 61 from top to bottom. The upper end of the spring shaft 61 is connected to the pressure rod assembly 50, and the lower end passes through the bottom plate 12 of the U-shaped base 10. Exemplarily, the upper end of the spring shaft 61 is threadedly connected to the pressure rod assembly 50. The upper limit member 62 is located between the pressure rod assembly 50 and the upper end of the spring 63, and the upper limit member 62 is fixed on the spring shaft 61. By adjusting the fixed position of the upper limit member 62, the elastic force of the spring 63 can be changed, so that the user can open and close the furnace cover more labor-saving. The lower end of the spring 63 is crimped onto the bottom plate 12 of the U-shaped base 10 through the lower stopper 64, and the sleeve assembly 70 is sleeved on the lower part of the spring shaft 61, and the sleeve assembly 70 abuts against the lower stopper 64. Generally, one or more gaskets 65 are provided at both ends of the spring 63. When disassembling the spring assembly 60, the spring assembly 60 is installed or disassembled as a whole. Therefore, the sleeve assembly 70 is first lifted upward along the spring shaft 61 to squeeze the spring 63, and the spring 63 is compressed and shortened and maintained in a compressed state. The upper end of the spring shaft 61 can be easily connected to or separated from the pressure rod assembly 50, thereby reducing the difficulty of disassembling the hinge and improving the disassembly efficiency.

[0035] One possible implementation of the upper limit member 62 is that the upper section of the spring shaft 61 is provided with threads, the upper limit member 62 is a first adjustment nut, and the upper limit member 62 is threadedly connected to the upper section of the spring shaft 61. By rotating the first adjustment nut, the length of the spring 63 can be adjusted, thereby adjusting the restoring force of the spring 63.

[0036] One possible implementation of the sleeve assembly 70 is: the lower section of the spring shaft 61 is also provided with threads, the sleeve assembly 70 includes a sleeve 71 and a second adjusting nut 72, the sleeve 71 is sleeved on the lower section of the spring shaft 61, the upper end of the sleeve 71 abuts against the lower limiter 64, and the lower end abuts against the second adjusting nut 72, that is, the sleeve 71 can also pass through the bottom plate 12 of the U-shaped base 10. The sleeve assembly 70 is only used when installing or disassembling the spring assembly 60, that is, the sleeve assembly 70 is installed on the spring shaft 61. Taking the disassembly of the spring assembly 60 as an example, the sleeve 71 is put on the spring shaft 61, and the second adjusting nut 72 is screwed in. The sleeve 71 is pushed to move upward, and the lower limit member 64 also moves upward to compress the spring 63. When the compression amount of the spring 63 is greater than the length of the spring shaft 61 inserted into the pressure rod assembly 50, the rotation of the second adjusting nut 72 can be stopped, and the spring shaft 61 is held and moved downward to separate the spring shaft 61 from the pressure rod assembly 50, and the spring assembly 60 can be taken out.

[0037] Preferably, a first through hole 13 for passing the spring shaft 61 is provided on the bottom plate 12 of the U-shaped base 10, the diameter of the first through hole 13 is smaller than the outer diameter of the lower stopper 64, and at the same time, the diameter of the first through hole 13 is larger than the outer diameter of the sleeve 71, and the outer diameter of the second adjusting nut 72 is ≤ the outer diameter of the sleeve 71. This arrangement allows the spring 63 to be compressed and kept in a compressed state by the sleeve assembly 70 when the spring assembly 60 is installed or removed, without manually pressing the spring 63 to keep it in a compressed state, saving time and effort, and making assembly and disassembly more convenient.

[0038] Please participate Figure 6 and Figure 7 The two first side plates 11 of the U-shaped base 10 are each provided with an arc-shaped limiting groove 14, and the end of the pressure rod assembly 50 passes through the arc-shaped limiting groove 14 and is fixedly connected to the rotating connecting member 20. Through the arc-shaped limiting groove 14, the furnace cover can be kept in a stopped state at the position of the maximum opening angle.

[0039] For example, see Figure 5The pressure rod assembly 50 includes a connecting rod 51 and a sleeve 52 sleeved on the outer circumference of the connecting rod 51. The sleeve 52 can be arranged one-to-one with the spring assembly 60, or multiple spring assemblies 60 can share one sleeve 52. The two ends of the connecting rod 51 are fixedly connected to the rotating connector 20, and the wall of the sleeve 52 is provided with a second through hole 521 for connecting the upper end of the spring shaft 61. A thread is arranged on the inner wall of the second through hole 521, and the spring shaft 61 and the second through hole 521 can be fixed by threaded connection. Preferably, the connecting rod 51 is a stainless steel shaft, and the sleeve 52 is a ductile iron pipe. Such a material combination can completely eliminate the sharp and harsh noise caused by the friction between the connecting rod 51 and the sleeve 52 when the furnace cover is opened and closed, thereby improving the user experience.

[0040] See also Figure 8 In order to improve the adjustability of the furnace cover and the furnace body when connected with the hinge, the furnace body connecting plate 30 is provided with a first strip hole 31, and the furnace cover connecting plate 40 is provided with a second strip hole 41. The first strip hole 31 and the second strip hole 41 are perpendicular to each other. The furnace body connecting plate 30 is fixed to the U-shaped base 10 by a fastener 80 passing through the first strip hole 31, and the furnace cover connecting plate 40 is fixed to the rotating connecting member 20 by a fastener 80 passing through the second strip hole 41. The furnace cover can be adjusted forward and backward, and the furnace body can be adjusted up and down, thereby ensuring the sealing between the furnace cover and the furnace body.

[0041] See also Fig. 9 In order to improve the stability of the U-shaped base 10, reinforcing ribs 15 are provided on both sides of the bottom plate 13. Fig. 9 and Fig.10 In order to better prevent dust and oil, the adjustable hinge also includes a shell 200, and the hinge body 100 is fixed in the shell 200.

[0042] The utility model discloses an adjustable hinge that is easy to assemble and disassemble. The installation process that can be implemented is as follows: when the furnace cover and the furnace body are fixedly connected to the furnace cover connecting plate 40 and the furnace body connecting plate 30 respectively, the spring assembly 60 is not installed in the hinge body 100. When there is no elastic force, the sealing of the furnace cover and the furnace body can be better adjusted. Then the spring assembly 60 is installed: after the spring 63 is compressed by the sleeve assembly 70, the spring shaft 61, together with the sleeve assembly 70, passes through the first through hole 13 from the inner cavity of the U-shaped base 10, and then the upper end of the spring shaft 61 is inserted into the second through hole 521 of the pressure rod assembly 50 and fixed. Then the sleeve assembly 70 is removed, and the lower end of the spring 63 is crimped on the bottom plate 12 of the U-shaped base 10 through the lower limit member 64. The elastic force is adjusted by changing the fixed position of the upper limit member 62 on the spring shaft 61.

[0043] The above description is only a specific implementation method of the utility model, and does not limit the patent scope of the utility model. Any equivalent structural transformation made using the contents of the utility model specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the utility model.
