[0024] The present application provides a dynamometer for building block splicing, which includes a main frame. Inside the main frame, a slide bar extending along the length direction is provided. A indicating member that can slide along the slide bar is sleeved on the slide bar. The indicating member is fixedly connected to a movable rod arranged inside the main frame. The movable rod can move along the slide bar following the indicating member. The lower end of the movable rod is connected with a hook, and the upper end is connected with an elastic member connected to the main frame. The elastic member has a tendency to reset after the movable rod moves downward.

[0025] As shown in the embodiment Figures 1 to 3 A dynamometer for building block splicing includes a main frame 1 assembled by building blocks. Inside the main frame 1, two parallel slide bars 2 extending along the length direction are provided, and there is a gap between the slide bars 2. A indicating member 3 that protrudes relative to the main frame 1 and can slide along the slide bar 2 is sleeved on the slide bar 2. The indicating member 3 is fixedly connected to a movable rod 4. The movable rod 4 is arranged in the gap between the two slide bars 2, and the size of the gap between the two slide bars 2 matches that of the movable rod 4. The movable rod 4 extends along the length direction of the main frame 1, can move along the slide bar 2 following the indicating member 3, and exposes from the lower end of the main frame 1. The lower end of the movable rod 4 is hinged with a hook 5 assembled by building blocks, and the hook 5 can rotate left and right or forward and backward relative to the main frame 1.

[0026] Furthermore, the main frame 1 includes a connecting member 6 arranged at its upper end. The connecting member 6 is respectively connected to the left and right sides of the main frame 1 to form the upper structure of the main frame 1. The dynamometer includes an elastic member 7. One end of the elastic member 7 is connected to the connecting member 6, and the other end is connected to the upper end of the movable rod 4. The elastic member 7 has a tendency to reset after the movable rod 4 moves downward, and the elastic force of the elastic member 7 counteracts the gravity of the heavy object hung on the hook 5, and then the gravity of the heavy object is reflected on the main frame 1 through the displacement tendency of the indicating member 3.

[0027] Specifically, the elastic member 7 can be a spring, a rubber band or an elastic rope, etc. In this embodiment, the elastic member 7 is an elastic rope.

[0028] Furthermore, the indicating member 3 is sleeved on the two slide bars 2 at the same time to maintain stability, and the indicating member 3 is a horizontally placed building block, which is convenient for intuitively observing the fluctuation of the force measured by the dynamometer.

[0029] Furthermore, a lifting part 8 hinged to the connecting member 6 is arranged at the upper end of the main frame 1.

[0030] Furthermore, the main body frame 1 includes a positioning member 9 fixedly connected to its lower end. The positioning member 9 is respectively connected to the left and right sides of the main body frame 1 to form the lower structure of the main body frame 1. On the left and right sides of the positioning member 9, there are respectively positioning portions 9.1 located inside the main body frame 1 and protruding upward to cooperate with the fixed sliding rod 2. The sliding rod 2 is inserted into the positioning portion 9.1. A positioning hole through which the movable rod 4 can pass is provided between the two positioning portions 9.1, and the size of the positioning hole matches the size of the movable rod 4.

[0031] Furthermore, each component of the above-mentioned dynamometer is assembled from building blocks and can be disassembled and assembled at will.

[0032] Working method and principle: When in use, lift the lifting portion 8 at the upper end of the main body frame 1, hang the heavy object on the hook 5, and then observe the displacement of the indicating member 3 to judge the magnitude of the gravity of the heavy object. Children can further understand the structure of the dynamometer by assembling the dynamometer, and stimulate their interest in physics during the play process.

[0033] Those skilled in the art should understand that 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-described 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.

[0034] The above-described embodiments only represent several implementation manners of the present application. Their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
