[0035] First embodiment

[0036] Reference Figure 1 and Figure 2 The application provides a locking device for installing on a spray inspection device and locking a spray inspection observation mechanism in the spray inspection device, comprising a rotating assembly and a locking assembly 4. The rotating assembly comprises a mounting shell 1, a spray inspection lifting block structure and a rotating mechanism 3. The spray inspection lifting block structure 2 is slidably arranged below the mounting shell 1 in the up-down direction. The rotating mechanism 3 is rotatably arranged in the interior of the mounting shell 1 and is rotatably connected to the top of the spray inspection lifting block structure 2. The rotating mechanism 3 is used to rotate downward when being in pressure contact with the spray inspection observation mechanism, thereby driving the spray inspection lifting block structure 2 to move downward. The locking assembly 4 comprises a locking seat 41, a locking rod 42 and a spring. The locking rod 42 is arranged on the locking seat 41. The bottom of the spray inspection lifting block structure 2 is provided with a locking hole relative to the locking rod 42. The top end of the locking rod 42 extends into the interior of the locking hole. The spring is sleeved on the locking rod 42. When the rotating mechanism 3 rotates downward, the spray inspection lifting block structure 2 slides downward along the locking rod 42. Since the outer diameter of the spring is greater than the diameter of the locking hole, when the bottom of the spray inspection lifting block structure 2 is in contact with the spring, the spring is compressed under force, thereby generating an upward rebound force. The spray inspection lifting block structure 2 is balanced under the horizontal pressure of the spray inspection observation mechanism and the upward rebound force of the spring. At this time, the spray inspection membrane is separated from the membrane supporting rod 6, thereby completing the locking of the spray inspection observation mechanism.

[0037] In some embodiments, the locking device further comprises a sliding rail 5 arranged below the mounting shell 1 in the vertical direction. The spray inspection lifting block structure 2 is slidably arranged on the sliding rail 5. The sliding of the spray inspection lifting block structure 2 in the vertical direction is limited by the sliding rail 5, thereby improving the moving accuracy of the spray inspection lifting block structure 2.

[0038] In some embodiments, the side surface of the spray inspection lifting block structure 2 is provided with a mounting groove. The sliding rail 5 is arranged in the interior of the mounting groove. The cross section of the sliding rail 5 and the mounting groove in the horizontal direction is matched and arranged in a dovetail shape. By opening the mounting groove on the side surface of the spray inspection lifting block structure 2, the shape of the mounting groove and the shape of the sliding rail 5 are matched, for example, the cross section of the sliding rail 5 and the mounting groove in the horizontal direction is matched and arranged in a dovetail shape, that is, the mounting groove is a dovetail groove, which can limit the sliding rail 5 and avoid the shaking of the sliding rail 5 in the horizontal direction.

[0039] In some embodiments, the rotating mechanism 3 comprises a rotating mechanism 3 body and a push rod 34, the rotating mechanism 3 body is arranged inside the installation housing 1. One end of the push rod 34 is connected with the rotating mechanism 3 body inside the installation housing 1, and the other end is extended out through the slot on the side of the installation housing 1 for pressure contact with the spray inspection observation mechanism. When the spray inspection observation mechanism moves horizontally to contact and press the push rod 34, the push rod 34 drives the rotating mechanism 3 to rotate downward, thereby driving the spray inspection lifting block mechanism 2 to slide downward along the slide rail 5. When the bottom of the spray inspection lifting block mechanism 2 contacts the spring, the spring is compressed under force to generate an upward rebound force, and the spray inspection lifting block mechanism 2 is balanced under the horizontal pressure of the spray inspection observation mechanism and the upward rebound force of the spring. At this time, the spray inspection film is separated from the film supporting rod 6, thereby completing the locking of the spray inspection observation mechanism.

[0040] In some embodiments, the rotating mechanism 3 body comprises a mounting support 31, a connecting rod 32 and a cam 33. The mounting support 31 is slidably connected with the inner side wall of the installation housing 1 on both sides and connected with the upper part of the spray inspection lifting block mechanism. The connecting rod 32 is located in the slot in the middle of the mounting support 31 and is rotationally connected with the inner side wall of the installation housing 1. The cam 33 is located in the slot and connected with the side of the connecting rod 32, and the cam 33 is also connected with the end of the push rod 34. When the push rod 34 is pressure contacted with the spray inspection observation mechanism, the cam 33 and the connecting rod 32 rotate relative to the mounting support 31, and the cam 33 is pressed on the bottom of the slot, thereby driving the mounting support 31 to slide downward, further pushing the spray inspection lifting block mechanism to move downward.

[0041] In some embodiments, the top of the locking seat 41 is further provided with a limiting circular table 411, and the locking rod 42 is arranged on the limiting circular table 411. The diameter of the limiting circular table 411 is greater than the diameter of the locking hole, and the limiting circular table 411 plays a role of controlling the maximum downward stroke of the spray inspection lifting block mechanism 2.

[0042] In some embodiments, the locking device further comprises two film supporting rods 6, which are located on both sides of the push rod 34. One end of each film supporting rod 6 extends into the interior of the installation housing 1, and the other end is used to support the spray inspection film. When the spray inspection lifting block mechanism 2 is balanced under the horizontal pressure of the spray inspection observation mechanism and the upward rebound force of the spring, the spray inspection film is separated from the film supporting rod 6 at this time, thereby completing the locking of the spray inspection observation mechanism.

[0043] First embodiment

[0044] The application also provides a spraying inspection unit comprising the locking device in any of the above embodiments. By rotating the rotating mechanism 3 downward, the spraying inspection lifting block mechanism 2 slides downward along the locking rod 42. When the bottom of the spraying inspection lifting block mechanism 2 contacts the spring, the spring is compressed to generate an upward rebound force because the outer diameter of the spring is larger than the diameter of the locking hole. The spraying inspection lifting block mechanism 2 is balanced under the horizontal pressure of the spraying inspection observation mechanism and the upward rebound force of the spring. At this time, the spraying inspection film is separated from the film supporting rod 6, thereby completing the locking of the spraying inspection observation mechanism.

[0045] In some embodiments, the spraying inspection unit in the present embodiment further comprises a spraying inspection observation mechanism which moves in a horizontal direction to be in pressure contact with the rotating mechanism 3. When the spraying inspection lifting block mechanism 2 is balanced under the horizontal pressure of the spraying inspection observation mechanism and the upward rebound force of the spring, at this time, the spraying inspection film is separated from the film supporting rod 6, thereby completing the locking of the spraying inspection observation mechanism.

[0046] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the protection scope of the present application.
