[0002] Seal rings are widely used in traditional mechanical hydraulic and pneumatic products, and the media to be sealed can be gases, liquids, powders, etc. Poor sealing will cause problems such as product failure maintenance and external leakage pollution. The T-shaped threaded seal ring is the most common seal, with the characteristics of simple structure, low cost, good sealing performance, convenient installation and use, and strong applicability. However, when detecting the T-shaped threaded seal ring, metal cones are generally used for detection, and the metal cones are extremely susceptible to the influence of environmental humidity, which will corrode the detection equipment, resulting in a greatly shortened service life of the detection equipment. Moreover, the metal cones have the characteristics of thermal expansion and contraction and are easily affected by environmental temperature, resulting in inaccurate detection of the inner diameter of the T-shaped threaded seal ring. At present, the metal cones can only detect the inner diameter and cannot detect the tensile ability, extrusion ability, etc. of the T-shaped threaded seal ring, and the detection function is single.

[0025] In order to make the purpose, technical solutions and advantages of the utility model more clear and understandable, the following further describes the utility model in detail with reference to the embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model.

[0026] Embodiment 1:

[0027] Refer to Figure 1, the present utility model provides a fiberglass T-shaped thread sealing ring inspection device, including a detection table 1 and an extrusion device 2. The detection table 1 and the extrusion device 2 are both detachably arranged on a sliding device 3, which is convenient for maintenance and disassembly. The detection table 1 is used to detect the tensile property and inner diameter of the T-shaped thread sealing ring 8, and the extrusion device 2 is used to extrude the T-shaped thread sealing ring 8 placed on the detection table 1 to detect its deformation ability. This device can be set on frames and boxes such as detection frames and detection boxes, and can be installed according to actual needs.

[0028] See Figure 1 and Figure 2 , the detection table 1 includes a first detection table 11 and a second detection table 12 with the same structure and arranged symmetrically in mirror image. The first detection table 11 and the second detection table 12 are combined to form a conical frustum structure. The purpose of setting it as a conical frustum structure is to be able to detect T-shaped thread sealing rings 8 with different inner diameters, and the applicable range is wide.

[0029] Scales 7 are arranged on both the first detection table 11 and the second detection table 12 to display the inner diameter data of the T-shaped thread sealing ring 8.

[0030] The extrusion device 2 includes a first extrusion part 21 and a second extrusion part 22 with the same structure and arranged symmetrically in mirror image. The first extrusion part 21 and the second extrusion part 22 can be combined to cover the outer side walls of the first detection table 11 and the second detection table 12.

[0031] See Figure 3 , the first extrusion part 21 includes an arc-shaped panel 210. A threaded rod 212 penetrating through its top and bottom is arranged on the arc-shaped panel 210. A pressure plate 211 is fixedly connected to the top of the threaded rod 212, and the bottom of the threaded rod 212 is rotatably connected to the sliding device 3; in order to limit the rotation of the arc-shaped panel 210, a limiting rod hole is arranged at the bottom of the arc-shaped panel 210, and a limiting rod 213 is arranged in the limiting rod hole. The limiting rod 213 is fixed on the sliding device 3. During use, the pressure plate 211 can be rotated to make the arc-shaped panel 210 can only move up and down under the action of the limiting rod 213. In order to ensure the slow up and down movement of the arc-shaped panel 210, a rubber sleeve 214 is sleeved outside the limiting rod 213. The second extrusion part 22 has the same structure as the first extrusion part 21, so it will not be described in detail.

[0032] The first detection table 11, the second detection table 12, the first extrusion part 21 and the second extrusion part 22 are all detachably installed on the sliding device 3. Specifically, the sliding device 3 includes a first forward and reverse screw rod 35, a second forward and reverse screw rod 36, a slide bar 37 and four sliding seats, and the four sliding seats are arranged side by side on the first forward and reverse screw rod 35, the second forward and reverse screw rod 36 and the slide bar 37. The arrangement order of the first forward and reverse screw rod 35, the second forward and reverse screw rod 36 and the slide bar 37 is not limited.

[0033] The four sliding seats are respectively a first sliding seat 31, a second sliding seat 32, a third sliding seat 33 and a fourth sliding seat 34. Among them, the second sliding seat 32 and the third sliding seat 33 are symmetrically arranged on the second forward and reverse screw rod 36 and are threadedly connected to the second forward and reverse screw rod 36 and slidably connected to the first forward and reverse screw rod 35 and the slide bar 37. The first forward and reverse screw rod 35 and the slide bar 37 only serve to support the second sliding seat 32 and the third sliding seat 33, and the second forward and reverse screw rod 36 serves to move the second sliding seat 32 and the third sliding seat 33. The first sliding seat 31 and the fourth sliding seat 34 are symmetrically arranged outside the second sliding seat 32 and the third sliding seat 33 and are threadedly connected to the first forward and reverse screw rod 35 and slidably connected to the second forward and reverse screw rod 36 and the slide bar 37. The second forward and reverse screw rod 36 and the slide bar 37 only serve to support the first sliding seat 31 and the fourth sliding seat 34, and the first forward and reverse screw rod 35 serves to move the first sliding seat 31 and the fourth sliding seat 34.

[0034] One end of the first forward and reverse screw rod 35 is connected to a first motor 4, one end of the second forward and reverse screw rod 36 is connected to a second motor 5, the other ends of the first forward and reverse screw rod 35 and the second forward and reverse screw rod 36 are both rotatably connected to the corresponding frame or box body through bearings 6, and both ends of the slide bar 37 are fixedly connected to the corresponding frame or box body.

[0035] The first detection table 11 is detachably connected to the second sliding seat 32 through a connecting rod 13, and the second detection table 12 is also detachably connected to the third sliding seat 33 through another connecting rod 13.

[0036] Rotatable threaded rods 212 and fixed limit rods 213 are connected to both the first sliding seat 31 and the fourth sliding seat 34. Among them, the arc-shaped panel 210 of the first extrusion part 21 is rotatably connected to the first sliding seat 31 through a threaded rod 212, and the arc-shaped panel 210 of the second extrusion part 22 is rotatably connected to the fourth sliding seat 34 through another threaded rod 212.

[0037] In order to make the structure more stable when the first detection table 11 and the second detection table 12 are combined, magnetic attraction magnet blocks 311 are provided on the side surfaces where the second sliding seat 32 and the third sliding seat 33 are connected.

[0038] The T-shaped thread sealing ring 8 in the present utility model is made of rubber, and its cross-section is T-shaped, which can be used at pipe joints and the like.

[0039] During use, start the second motor 5 and rotate it forward. Under the action of the second forward and reverse lead screw 36, drive the second sliding seat 32 and the third sliding seat 33 to move towards each other. The first forward and reverse lead screw 35 and the slide bar 37 only play a supporting role and do not limit the movement of the second sliding seat 32 and the third sliding seat 33. When the second sliding seat 32 and the third sliding seat 33 abut against each other, under the action of the magnet block 311, they are connected more firmly. At this time, the first detection table 11 and the second detection table 12 are combined into a whole conical table shape. The T-shaped thread sealing ring 8 to be detected is sleeved on the detection table 1 of the conical table. The T-shaped thread sealing ring 8 descends to a suitable position by its own gravity. At this time, the corresponding scale 7 shows the inner diameter data corresponding to the current T-shaped thread sealing ring 8. When the inner diameter detection is qualified, according to the requirement of tensile performance, start the second motor 5 and rotate it in the reverse direction. Under the action of the second forward and reverse lead screw 36, drive the second sliding seat 32 and the third sliding seat 33 to move away from each other to a suitable position. When the second motor 5 is started and the second forward and reverse lead screw 36 rotates in the reverse direction, at this time start the first motor 4 and rotate it forward. Under the action of the first forward and reverse lead screw 35, drive the first sliding seat 31 and the fourth sliding seat 34 to move towards each other so that the arc-shaped panels 210 corresponding to the first pressing part 21 and the second pressing part 22 are pressed on the T-shaped thread sealing ring 8, as Figure 4 shown. The height of the arc-shaped panel 210 can be adjusted by rotating the pressure plate 211. At the same time, the pressure plate 211 can also press the T-shaped thread sealing ring 8 when the arc-shaped panel 210 presses the T-shaped thread sealing ring 8 to prevent the T-shaped thread sealing ring 8 from popping out. After the detection is completed, the first motor 4 drives the first forward and reverse lead screw 35 to rotate in the reverse direction, so that the first pressing part 21 and the second pressing part 22 move away from each other and return to their original positions, while the second motor 5 drives the second forward and reverse lead screw 36 to rotate forward, so that the second sliding seat 32 and the third sliding seat 33 move towards each other until the first detection table 11 and the second detection table 12 are combined into a whole conical table shape, and then remove the T-shaped thread sealing ring 8 and conduct the next detection of the T-shaped thread sealing ring 8. If the removed T-shaped thread sealing ring 8 is intact, it means it is qualified. If there are cracks, deformations or fractures, etc., it means it is unqualified.
