Technical Field

[0001] The utility model relates to the technical field of airtightness detection, in particular to an airtightness detection table for the middle shell of a sighting device. Background Technique

[0002] During the production process of the middle shell of a sighting device, certain requirements are imposed on its airtightness. Therefore, after production, it is necessary to detect the airtightness, and thus an airtightness detection table is required. For example, in the patent with the publication number "CN209525068U" and the patent name "Airtightness Detection Machine", the leak detection upper mold is used to cooperate with the leak detection lower mold to achieve the airtightness detection of the product. Specifically, it includes: a sealing cover plate, a cylinder for driving the sealing cover plate to move up and down, and a leak detection bracket for fixing the cylinder. Among them, the leak detection bracket is a gantry, which is fixed on the machine table of the airtightness detection machine, and the side lower mold is installed on the push-pull carrier and is located below the leak detection upper mold. When it moves to directly below the leak detection upper mold under the push of the push-pull carrier, it can form a mold closure with the leak detection upper mold. However, the following problems still exist in the actual use of the above structure:

[0003] In the use process of the above structure, it is not convenient to fix the middle shell of the sighting device, which leads to poor detection effect. At the same time, due to the structural characteristics of the middle shell of the sighting device, it is necessary to carry out sealing treatment during detection to complete the airtightness detection. However, the above structure cannot carry out airtightness detection on it, so its use has limitations.

[0004] Therefore, we propose an airtightness detection table for the middle shell of a sighting device, which can well solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide an airtightness detection table for the middle shell of a sighting device to solve the problems in the above background technique that it is not convenient to fix the middle shell of the sighting device in the current market, resulting in poor detection effect, and at the same time, due to the structural characteristics of the middle shell of the sighting device, it is necessary to carry out sealing treatment during detection to complete the airtightness detection.

[0006] To achieve the above purpose, the utility model provides the following technical solution: An airtightness detection table for the middle shell of a sighting device, including a machine body, and a vertical plate is fixed on the rear side of the machine body;

[0007] It further includes: a vertical rod is fixed on the upper end surface of the machine body, and a lower sealing gasket is sleeved on the outer side of the lower end of the vertical rod. At the same time, a threaded rod is arranged at the upper end of the vertical rod, and the lower end of the threaded rod extends into the vertical rod, and the lower end of the threaded rod is connected to the vertical rod by a bearing;

[0013] Preferably, the inner side of the moving plate is arranged in an arc structure, and a lateral sealing pad is bonded to the inner side of the moving plate.

[0014] Preferably, a second cylinder is fixed to the upper surface of the vertical plate, and the output end of the second cylinder penetrates through the vertical plate and is fixed to the detection mechanism.

[0015] Preferably, the upper end surface of the detection mechanism is communicated with one end of the air delivery pipe, the other end of the air delivery pipe penetrates through the vertical plate and is communicated with the air pump, and the air pump is fixed to the surface of the vertical plate.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows: The airtightness detection table for the middle shell of the sighting device not only achieves the fixing effect, thereby ensuring the stability during detection, and at the same time, there will be no deviation phenomenon, which can enable the detection mechanism to better detect its airtightness, and further fix it. At the same time, it can also achieve the sealing effect, thereby ensuring the accuracy of the airtightness detection. The specific content is as follows:

[0017] By rotating the threaded rod to drive the lifting plate to descend, when the lifting plate descends, the outer support block is driven to prop up outward through the second connecting rod, so that the outer support blocks move outward and contact and press the inner wall of the middle shell of the sighting device, thereby achieving the fixing effect, ensuring the stability during detection, and at the same time, there will be no deviation phenomenon, which can enable the detection mechanism to better detect its airtightness;

[0018] First, the middle shell of the sighting device is sleeved on the outer side of the vertical rod. The vertical rod is used to position the middle shell of the sighting device.

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Please refer toFigures 1-6 , the present utility model provides the following technical solutions:

[0031] Embodiment 1: In order to solve the problem in the prior art that it is not convenient to fix the middle shell of the sighting device, which leads to poor detection effect. At the same time, due to the structural characteristics of the middle shell of the sighting device, it is necessary to carry out sealing treatment during detection to complete the airtightness detection. Therefore, the following solution is disclosed. It includes a machine body 1, and a vertical plate 12 is fixed at the rear side of the machine body 1; it also includes: a vertical rod 2 is fixed on the upper end surface of the machine body 1, and a lower sealing gasket 3 is sleeved on the outer side of the lower end of the vertical rod 2. At the same time, a threaded rod 7 is arranged at the upper end of the vertical rod 2, and the lower end of the threaded rod 7 extends into the vertical rod 2, and the lower end of the threaded rod 7 is connected to the vertical rod 2 by a bearing; a lifting plate 8 is threadedly connected to the outer side of the threaded rod 7, and a second connecting rod 6 is rotatably connected to the outer side of the lifting plate 8, and the outer end of the second connecting rod 6 extends out of the outer side of the vertical rod 2 and is rotatably connected to an outer support block 4; the inner side below the outer support block 4 is rotatably connected to one end of a first connecting rod 5, and the other end of the first connecting rod 5 is rotatably connected to the vertical rod 2;

[0032] First, sleeved the middle shell of the sighting device on the outer side of the vertical rod 2, and the vertical rod 2 is used to position the middle shell of the sighting device. At the same time, when the sleeving is completed, the lower end of the middle shell of the sighting device will contact the lower sealing gasket 3. At this time, the lower end surface can be sealed. At the same time, the threaded rod 7 can be rotated. By rotating the threaded rod 7, the threaded rod 7 drives the lifting plate 8 to descend. When the lifting plate 8 descends, it will drive one end of the second connecting rod 6 to descend together. Through the rotational connection between the other end of the second connecting rod 6 and the outer support block 4, the outer support block 4 is supported outward. At the same time, with the cooperation of the outer support block 4 and the first connecting rod 5, the stable effect of the outer support block 4 is realized. Then the outer support blocks 4 move outward and contact and squeeze the inner wall of the middle shell of the sighting device, thus realizing the fixing effect, ensuring its stability during detection, and at the same time, there will be no deviation phenomenon, so that the detection mechanism can better detect its airtightness;

[0033] Embodiment 2: Different from Embodiment 1, this embodiment is convenient for airtightness detection. Specifically, refer to Figures 1-3 , on the left and right sides of the vertical rod 2 on the upper surface of the machine body 1, a first cylinder 9 is fixed, and the output end of the first cylinder 9 is fixed to a moving plate 10. The inner side of the moving plate 10 is arranged in an arc structure, and a lateral sealing gasket 11 is adhered to the inner side of the moving plate 10. A second cylinder 13 is fixed on the upper surface of the vertical plate 12, and the output end of the second cylinder 13 penetrates through the vertical plate 12 and is fixed to a detection mechanism 14. The upper end surface of the detection mechanism 14 is communicated with one end of an air delivery pipe 16, and the other end of the air delivery pipe 16 penetrates through the vertical plate 12 and is communicated with an air pump 15, and the air pump 15 is fixed on the surface of the vertical plate 12;

[0034] Meanwhile, by starting the first cylinder 9, the two groups of first cylinders 9 drive the moving plate 10 fixed to their output ends to move inward, so that the moving plate 10 drives the lateral sealing gasket 11 to contact the outer side of the middle housing of the sight, further fixing it and achieving a sealing effect, thus ensuring the accuracy of the airtightness detection. Then, the second cylinder 13 can be started, so that the second cylinder 13 drives the detection mechanism 14 to descend, making the detection mechanism 14 move to contact the middle housing of the sight. At the same time, the air pump 15 is started, so that the air pump 15 conveys gas through the air delivery pipe 16 to the detection mechanism 14, and then the detection mechanism 14 sends the gas into the middle housing of the sight. Subsequently, the airtightness can be detected by the detection mechanism 14;

[0035] Embodiment 3: Different from Embodiment 2, this embodiment facilitates removing the middle housing of the sight. Specifically, refer to Figures 2-6 , there are four groups of outer support blocks 4, and the outer support blocks 4 are arranged in a hemispherical structure. Four groups of second connecting rods 6 are rotatably connected to the outside of the lifting disc 8, and the lifting disc 8 is arranged inside the vertical rod 2;

[0036] Moreover, after the detection is completed, only need to control the second cylinder 13 to drive the detection mechanism 14 upward, and at the same time control the first cylinder 9 to drive the moving plate 10 away from the middle housing of the sight. At this time, the threaded rod 7 can be rotated reversely, so that the threaded rod 7 drives the lifting disc 8 connected by threads to rise, so that the lifting disc 8 drives the second connecting rod 6 to rise together, so that the second connecting rod 6 drives the outer support block 4 to move inward, so that the outer side of the outer support block 4 no longer contacts and presses the inner wall of the middle housing of the sight. At this time, the middle housing of the sight can be removed.
