[0033] The embodiments of the present application will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present application, and should not be construed as a limitation to the present application.

[0035] In the description of the present application, the meaning of several is one or more, and the meaning of multiple is at least two. Understandings such as greater than, less than, exceeding, etc. do not include the present number, and understandings such as above, below, within, etc. include the present number. If there is a description of first and second, it is only for the purpose of distinguishing technical features and should not be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or implicitly indicating the sequence relationship of the indicated technical features.

[0036] In the description of this application, unless otherwise clearly defined, terms such as "setting", "installation", "connection", etc. should be understood in a broad sense. Those skilled in the art can reasonably determine the specific meanings of the above terms in this application after combining the specific content of the technical solution.

[0037] Referring to Figures 1 to 4 , the flipping limit mechanism of the first aspect embodiment of this application is applied to a manual inspection fixture or a fixture with a flipping block 500, etc. The flipping limit mechanism includes a connecting block 100, a sliding shaft 200, and an elastic member 300.

[0038] One end of the sliding shaft 200 is provided with a clamping head 210. The sliding shaft 200 is slidably arranged on the connecting block 100 along the axial direction, so that the clamping head 210 can be stuck in the flipping path of the flipping block 500 when it extends, and can enable the flipping block 500 to pass through when it retracts; the elastic member 300 is used to provide an elastic force acting on the sliding shaft 200, so that the clamping head 210 can be maintained in or reset to the extended state.

[0039] It can be understood that through the sliding fit of the sliding shaft 200 and the connecting block 100, and using the elastic member 300 to realize the function of automatically rebounding after sliding expansion and contraction, combined with the flipping structure of the manual inspection fixture, it realizes rapid opening and closing, saves the time for fixture inspection, and as much as possible eliminates the risk of damage caused by dropping of the flipping mechanism of the manual inspection fixture in the open state.

[0040] In some embodiments, this flipping limit mechanism is installed on a detection device or a fixture device with a flipping block 500. When installed, the clamping head 210 of the sliding shaft 200 can span the flipping path of the flipping block 500 when it extends. Specifically, when in use, when the flipping block 500 needs to be flipped open, an external force is used to retract the sliding shaft 200 so that the flipping block 500 can be opened smoothly. After opening, the external force applied to the sliding shaft 200 is cancelled. At this time, the sliding shaft 200 is reset under the action of the elastic member 300 and maintained in the extended state. If the flipping block 500 accidentally drops from the open state, it will be stuck by the clamping head 210 on the flipping path, thus achieving the effect of preventing dropping and damage. And the whole process does not require locking the sliding shaft 200, realizing rapid opening and closing, and saving the time for fixture inspection.

[0041] In some embodiments of the present application, the card head 210 includes an abutting inclined surface 211. The abutting inclined surface 211 is arranged to incline towards the opening direction of the flipping block 500, so that the flipping block 500 can contact the abutting inclined surface 211 when opening to push the card head 210 to retract. It can be understood that the end of the sliding shaft 200 in contact with the flipping block 500 is the card head 210; one surface of the card head 210 in contact with the flipping block 500 during the opening action of the flipping block 500 is made into an inclined surface, and there is a lateral force at an angle to the force applied when the flipping block 500 opens, realizing that the sliding shaft 200 naturally rebounds and retracts after being stressed, and the flipping block 500 opens smoothly, that is, the external force applied to the sliding shaft 200 is provided by the flipping block 500, further improving the use efficiency.

[0042] In some embodiments, the sliding shaft 200 is parallel to the axis of rotation of the flipping block 500 to make it easier to arrange the sliding shaft 200.

[0043] In some embodiments of the present application, the card head 210 includes a clamping surface 212 opposite to the abutting inclined surface 211, so that the flipping block 500 can be abutted against the clamping surface 212 and limited when closing. It can be understood that one surface of the card head 210 in contact with the closing flipping block 500 is made into the clamping surface 212. When the sliding shaft 200 is a columnar structure, the clamping surface 212 is arranged as a cylindrical surface. At this time, the downward pressure when the flipping mechanism closes is perpendicular to the cylindrical surface of the card head, and the flipping block 500 is limited from closing.

[0044] It can be understood that the card head on the side where the sliding shaft 200 contacts the flipping block 500 when opening is made into an "inclined surface", and the card head on the side where the sliding shaft 200 contacts the flipping block 500 when closing is made into a "cylindrical surface". When the flipping block 500 flips from the closed state to the open state, the inclined surface of the card head is laterally pressed by the flipping block 500, and the sliding shaft 200 can elastically retract, and the flipping block 500 opens smoothly; after the flipping block 500 crosses the limiting small mechanism, the limiting small mechanism makes the sliding shaft 200 rebound to the normal position; when the flipping block 500 falls, the cylindrical surface of the card head of the sliding shaft 200 will hold the flipping block 500, restricting the flipping block 500 from closing, realizing the function of preventing the flipping block 500 from accidentally falling; when it is necessary to close the flipping block 500, the sliding shaft 200 can be pulled by hand to apply a lateral force to pull back the sliding shaft 200, so that the cylindrical surface of the card head of the sliding shaft 200 disengages from the flipping block 500, and at this time the flipping block 500 can be closed.

[0045] In some embodiments of the present application, the flip limit mechanism further includes a locking member 400, which is used to adjust the elastic force provided by the elastic member 300. It is understandable that, in addition to the function of reliably mounting the sliding shaft 200 on the connecting block 100, the locking member 400 can also adjust the elastic force of the elastic member 300 acting on the sliding shaft 200 by controlling the axial mounting position of the sliding shaft 200.

[0046] In some embodiments of the present application, a limiting boss 220 is provided on one end of the sliding shaft 200 relatively close to the clamping portion 210, and the elastic member 300 is a spring, which is sleeved on the sliding shaft 200 and located between the limiting boss 220 and the connecting block 100. It can be understood that by installing a spring between the connecting block 100 and the sliding shaft 200, the automatic rebound function of the sliding shaft 200 after being squeezed or pulled is realized, and the clamping column surface of the sliding shaft 200 is kept in a position that can prevent the flip block 500 from closing in a natural state.

[0047] In some embodiments of the present application, a threaded structure 230 is provided at the other end of the sliding shaft 200 opposite to the clamping portion 210, and the locking member 400 is a locking nut, which is adjustably arranged on the threaded structure 230 and is used to adjust the elastic force provided by the elastic member 300. It can be understood that the thread size of the locking nut matches the threaded structure 230 of the sliding shaft 200, so as to lock and assemble the sub-parts together.

[0048] In some embodiments, the thread structure 230 of the sliding shaft 200 is a threaded column.

[0049] In some embodiments of the present application, a sliding groove 240 is provided on the side wall of the sliding shaft 200, and a sliding part is provided on the connecting block 100, and a part of the sliding part is slidably arranged on the sliding groove 240, so that the sliding shaft 200 has a preset sliding stroke. It can be understood that the sliding shaft 200 is slidably connected to the connecting block 100, so that the sliding shaft 200 can achieve stable sliding. The width of the sliding groove 240 is used to control the sliding stroke. After the limiting slot hole of the connecting block 100 is screwed into the sliding part, the sliding part will be supported by the two sides of the sliding groove 240, thereby realizing the limitation of the sliding stroke. The diameter of the sliding groove 240 surface is larger than the diameter of the limiting slot hole of the connecting block 100 to prevent the sliding part from sliding out of the connecting block 100.

[0050] In some embodiments, the sliding portion is a bolt, and the limiting slot hole of the connecting block 100 is a threaded hole, which limits the sliding stroke of the sliding shaft 200 after the corresponding bolt is screwed into the hole.

[0051] In some embodiments of the present application, a ball head handle 250 is provided at the other end of the sliding shaft 200 opposite to the clamping head portion 210. It can be understood that the ball head handle 250 is used to provide a handle for manual gripping force, and can also be designed into other shaped handles according to specific circumstances.

[0052] In some embodiments, a matching threaded hole is made in the center of the handle and connected to the threaded column of the sliding shaft 200. One end of the threaded column is tightly connected to the locking nut and the ball head handle 250 by threading.

[0053] In some embodiments, the diameter of the sliding through hole of the connecting block 100 is slidably matched with the diameter of the sliding shaft 200, so that the sliding shaft 200 can stably slide within the hole of the connecting block 100. The connecting block 100 also has a connecting hole reserved for connection, so that the flipping limiting mechanism can be smoothly connected and fixed to the inspection tool device.

[0054] In some embodiments of the present application, through the sliding fit of the sliding shaft 200 and the connecting block 100, and by adding a spring in the combination to achieve the function of automatic rebound after sliding expansion and contraction, a small retractable and reboundable mechanism is formed; combining this small mechanism with the flipping structure of the manual inspection tool, and making the clamping head position of this small mechanism in contact with the flipping block 500 into a suitable force-bearing structure, a flipping limiting small mechanism with retractable and reboundable function is formed. This design eliminates the risk of damage caused by anti-falling when the manual inspection tool flipping mechanism is in the open state, and at the same time can achieve rapid opening and closing, saving the time for inspection tool detection.

[0055] Refer to Figures 1 to 4 , for the inspection tool device of the second aspect embodiment of the present application, the inspection tool device can be a manual inspection tool for certain products that require a flipping mechanism. The inspection tool device includes the flipping limiting mechanism of the first aspect embodiment of the present application, which can avoid the situation where the flipping block 500 may fall down during use and improve the use efficiency.

[0056] Refer to Figures 1 to 4 , for the production line of the third aspect embodiment of the present application, the production line can include the inspection tool device of the second aspect embodiment of the present application, and can also include upstream production devices, downstream packaging devices, etc. to form a production line for corresponding products. Since this inspection tool device has the flipping limiting mechanism of the first aspect embodiment of the present application, it can ensure the production efficiency and reduce the occurrence of product defects.

[0057] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
