DETAILED DESCRIPTION

[0011] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0012] like Figures 1 to 3 As shown, a force-applying and measuring device for the linkage ring of an air intake casing assembly comprises a push-pull rod 1, a dynamometer 2, a rack rod 3, a gear 4, a force transmission shaft 5, a force-applying handle 6, a support seat 7, an adapter shaft 8, a pad 9 and an adapter bracket 10; a first through hole 11 is horizontally provided on the top of the support seat 7, the force transmission shaft 5 is inserted into the first through hole, a first bushing 12 and a second bushing 13 are respectively installed between the force transmission shaft 5 and the first through hole 11, and the force transmission shaft 5 has only rotational freedom relative to the first bushing 12 and the second bushing 13; the gear 4 is fixedly sleeved on the force transmission shaft 5 and is located between the first bushing 12 and the second bushing 13; a second through hole 14 is horizontally provided inside the support seat 7 below the first through hole 11, and the second through hole 14 is perpendicular to the axis of the first through hole 11; The rack rod 3 is installed in the second through hole 14, and the rack rod 3 is meshed with the gear 4; the force handle 6 is connected to the outermost end of the force transmission shaft 5; one end of the push-pull rod 1 is hinged to the ear seat on the linkage ring 15, and the other end of the push-pull rod 1 is fixedly connected to one end of the rack rod 3 through the dynamometer 2; a third through hole 16 is horizontally opened at the bottom of the support seat 7, and the third through hole 16 is parallel to the first through hole 11; the adapter shaft 8 is installed in the third through hole 16, and the adapter shaft 8 has rotational freedom relative to the third through hole 16; the adapter bracket 10 adopts an L-shaped structure, and the vertical arm of the adapter bracket 10 is connected to the adapter shaft 8, and the pad 9 is arranged between the support seat 7 and the vertical arm of the adapter bracket 10, and the horizontal arm of the adapter bracket 10 is fixedly connected to the air intake casing assembly with a flip car.

[0013] The following describes a one-time use process of the present invention in conjunction with the accompanying drawings:

[0014] First, the adapter bracket 10 in the force-applying and measuring device of the linkage ring of the air intake casing assembly of the present invention is fixedly connected to the air intake casing assembly using a turning car to ensure that the adapter bracket 10 is firmly connected. Then, the push-pull rod 1 is hinged to the ear seat on the linkage ring 15 of the air intake casing assembly. At this time, the installation of the present invention is completed.

[0015] When push-pull force measurement is required, just hold and turn the force applying handle 6. The rotation of the force applying handle 6 will drive the force transmission shaft 5 to rotate, and then drive the gear 4 thereon to rotate. Under the action of meshing transmission, the rotating gear 4 will convert the rotational motion into a linear movement of the rack rod 3, and finally generate a push-pull force on the push-pull rod 1 through the movement of the rack rod 3. The value of the push-pull force is directly obtained through the dynamometer 2, thereby realizing efficient and rapid measurement of the push-pull force.

[0016] In addition, if there is a relative swinging displacement during the process of applying force through the force handle 6, since the bottom of the support seat 7 is connected to the adapter bracket 10 through the adapter shaft 8, the entire mechanism can be rotated to ensure smooth measurement of the push and pull force.

[0017] The solutions in the embodiments are not intended to limit the patent protection scope of the present invention. Any equivalent implementation or modification that does not deviate from the present invention is included in the patent scope of this case.
