Detailed Description

The following describes the embodiments of the present utility model further with reference to the drawings. The description of these embodiments is provided to assist understanding of the present utility model, but is not intended to limit the present utility model. In addition, the technical features of the embodiments of the present utility model described below may be combined with each other as long as they do not collide with each other.

Seals, such as oil seals, are mechanical elements used to seal oil, which isolate components of the transmission components that require lubrication from the output components, and which do not allow the lubrication to leak. When the maintenance is needed, the oil seal (or the water seal) needs to be taken out, and a special oil seal dismounting tool does not exist in the prior art, so that the conditions of insufficient dismounting efficiency and easy damage to the sealing element occur, and the sealing effect is easily affected when the damaged sealing element is reinstalled.

According to the technical scheme, the nondestructive oil seal taking-out tool solves the problems of inconvenient disassembly and assembly and poor sealing effect of an oil seal in the prior art, and has the beneficial effects of facilitating disassembly and ensuring sealing performance when the article taking component 100 and the adjusting component 200 are combined and a channel 105 penetrates through the middle of the article taking component 100.

The general idea of the embodiment of the utility model for solving the technical problems is as follows:

because the device comprises the object taking part 100 and the adjusting part 200, the middle of the object taking part 100 is penetrated with a channel 105, the wall of the channel 105 is provided with an internal thread 115, and the outer surface of the adjusting part 200 is provided with a series of technical means such as an external thread 215 matched with the channel 105 of the internal thread 115. The object taking part 100 is screwed to touch the nesting end 120 (taper valve) of the bottom sealing part, the nesting end and the structure thereof are tightly matched with the main water seal and the auxiliary water seal, and the object taking part is pulled out slightly, so that the object taking part is disassembled without damage and no scraps are generated.

Specifically, the channel 105 of the fetching component 100 is penetrated by an adjusting component 200, and the adjusting component 200 adjusts the overall length (adjusts the expansion and contraction) so as to be convenient for fetching the sealing element. When the object taking part 100 is extruded into the sealing element (water seal) to be disassembled, the main water seal and the auxiliary water seal to be disassembled are tightly matched, the object taking part is pulled out slightly, and the sealing element is not damaged.

In order to better understand the above technical solutions, the following detailed description will refer to the accompanying drawings and specific embodiments.

A nondestructive oil seal taking-out tool is shown in fig. 1 and comprises an object taking component 100 and an adjusting component 200, wherein a channel 105 is penetrated in the middle of the object taking component 100, an inner thread 115 is arranged on the wall of the channel 105, and an outer thread 215 matched with the channel 105 of the inner thread 115 is arranged on the outer surface of the adjusting component 200.

Specifically, one end of the fetching component 100 is a sealing element nesting end 120, and one end of the fetching component 100 away from the sealing element nesting end 120 is provided with a first rotary handle 110; one end of the adjustment member 200 is inserted into the channel 105 and the end of the adjustment member 200 remote from the channel 105 is provided with a second rotatable handle 210.

Specifically, the seal nest end 120 is tapered. The first rotatable handle 110 is connected to the body of the picking member 100.

When the sealing element needs to be taken out, for example, when the water seal or the oil seal needs to be taken out, the first rotary handle 110 is rotated clockwise to squeeze the conical sealing element nesting end 120 of the object taking part 100 into the water seal or the oil seal, and after the largest diameter part of the sealing element nesting end 120 is squeezed into the water seal or the oil seal according to the principle of driving an explosion screw into a wall body, the sealing element nesting end 120 is clamped in the water seal or the oil seal because the diameter of the largest diameter part of the sealing element nesting end 120 is larger than that of the water seal or the oil seal, the object taking part 100 is slightly pulled back or the first rotary handle 110 is rotated anticlockwise to retract the object taking part 100 (the oil seal or the opposite direction of the position of the water seal), and the water seal or the oil seal serving as the sealing element is taken back, so that the sealing element can be taken out quickly in a nondestructive state.

The handle facilitates screwing of the takeout member 100, however, the length of the takeout member 100 or the configuration of the seal nesting end 120 required for the depth of the different sized oil or water seals and their location is different, and the removable takeout member 100 is used to accommodate different scenarios.

As shown in fig. 2, the first twist grip 110 is detachably attached to the body of the takeout member 100.

Specifically, the length of the adjustment member 200 is greater than the length of the takeout member 100.

More specifically, the length of the first rotary handle 110 is greater than the length of the second rotary handle 210.

In particular, the first and second rotary handles 110 and 210 are cylindrical in shape.

When the seal needs to be taken out, for example, when the water seal or the oil seal needs to be taken out, the first rotary handle 110 is rotated clockwise to squeeze the conical seal nested end 120 of the object taking part 100 into the water seal or the oil seal, and after the largest diameter part of the seal nested end 120 is squeezed into the water seal or the oil seal according to the principle of driving an explosion screw into a wall body, the largest diameter part of the seal nested end 120 is larger than the diameter of the water seal or the oil seal, so that the seal nested end 120 is clamped in the water seal or the oil seal, the object taking part 100 is pulled back slightly or the second rotary handle 210 is rotated slightly back clockwise at the same time, and the object taking part 100 is retracted (the opposite direction of the position where the oil seal or the water seal is located) at the same time when the first rotary handle 110 is rotated anticlockwise, the second rotary handle 210 is rotated clockwise to take the water seal or the oil seal as the seal of the seal, so that the seal is taken back efficiently in a nondestructive state is further realized.

The tool is a special tool for nondestructively disassembling a high-pressure sealing piece (containing water seal) which is designed and developed aiming at actual requirements in the maintenance process of a high-pressure cleaning machine.

Specifically, the principle is that the main body is provided with six small grooves, and the main body is formed by turning and cutting. In the use process, the bottom cone valve is pulled by screwing the bolt, so that the proper position of the slotting part is expanded, the slotting part is tightly matched with the main water seal and the auxiliary water seal to be disassembled, and the slotting part is slightly pulled out, thereby realizing nondestructive disassembly. When the water seal is removed, the screw rod is rotated anticlockwise, the screw rod is automatically restored to the original state, and the disassembly is completed.

By using the nondestructive oil seal dismounting tool, the nondestructive dismounting efficiency of the high-pressure sealing element including the oil seal is effectively improved.

The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings, but the present utility model is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the utility model, and yet fall within the scope of the utility model.
