DETAILED DESCRIPTION

[0030] In order to make the person in the art better understand the utility model scheme, below will combine the drawings in the embodiments of the utility model, the technical scheme in the embodiments of the utility model is clearly and completely described, obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor should belong to the scope of the utility model protection.

[0031] As shown in Figures 1-5 A locking device for indentation tester, comprising main part 1, rotating shaft 2, movable piece 3 and elastic body 4. The main part 1 is provided with boss 11 for supporting object, and connecting seat 12 connected with boss 11. The boss 11 extends outwardly relative to the connecting seat 12, for supporting the clamped object, and specifically to the actual use, the object is mainly the carrier equipment that can place test sample, to realize the installation of indentation tester and carrier equipment, facilitate indentation test.

[0032] As shown in Figure 3 , Figure 4 The rotating shaft 2 is arranged on the side of the connecting seat 12 towards the boss 11, and has a cutting surface 21. Specifically, the rotating shaft 2 is semicircular in cross section, and the bottom surface thereof facing the boss 11 is the cutting surface 21, and the cutting surface 21 has arc transition surfaces 211 at both ends. The movable piece 3 has a mounting hole 31 formed inside and an eccentric convex part 32 formed outside, the mounting hole 31 is sleeved on the rotating shaft 2, and the movable piece 3 is elongated outwardly to form a knob 33, which provides a force point for the operator to rotate the movable piece 3.

[0033] The elastic body 4 is arranged in the mounting hole 31 and abuts against the cutting surface 21 of the rotating shaft 2. Specifically, as shown in Figure 3 Figure 4 , the elastic body 4 is located below the rotating shaft 2 and has a smooth surface 41 abutting against the cutting surface 21 and a circular arc surface 42 abutting against the inner wall of the mounting hole 31. The clearance between the circular arc transition surface 211 at both ends of the cutting surface 21 and the circular arc surface 42 of the elastic body 4 can reduce the sliding friction between the rotating shaft 2, the elastic body 4 and the inner wall of the mounting hole 31, so that the rotating of the movable part 3 is smoother. The clearance between the circular arc transition surface 211, the circular arc surface 42 and the mounting hole 31 also provides a deformation space for the elastic body 4, which facilitates the deformation of the elastic body 4 under the extrusion of the movable part 3 during the rotation of the movable part 3, thereby providing sufficient downward pressure for the movable part 3 on the basis of ensuring the smooth rotation of the movable part 3, so that the eccentric protrusion 32 can stably hold the clamped object. Meanwhile, the elastic property of the elastic body 4 can provide a certain elastic buffer space for the movable part 3, so that the movable part 3 can be upwardly offset relative to the rotating shaft 2. Even if the thickness of the clamped object is greater than the distance between the movable part 3 and the boss 11, the movable part 3 can be upwardly offset under the extrusion of the clamped object to place the clamped object between the movable part 3 and the boss 11, thereby being applicable to clamped objects of various thicknesses and having strong practicability.

[0034] In this embodiment, the smooth surface 41 is in smooth contact with the cutting surface 21. Of course, in other embodiments, the smooth surface 41 and the cutting surface 21 can form a wavy surface to increase the friction between the elastic body 4 and the rotating shaft 2, stabilize the relative position of the elastic body 4 and the rotating shaft 2, and prevent the displacement of the elastic body 4.

[0035] The movable part 3 is rotated by applying an external force, and the eccentric protrusion 32 can realize the locking or unlocking of the object on the boss 11. Specifically, taking the direction shown in Figure 4 as an example, when the actuating part 33 is vertically upward, the distance between the movable part 3 and the boss 11 is greater than or equal to the thickness of the clamped object, at this time, the locking device is in an unlocked state, which facilitates the placement of the object on the boss 11 and ensures the smooth entry of the object into the predetermined position, thereby preparing for subsequent operation. The movable part 3 is rotated clockwise by pulling the actuating part 33, and since the thickness of the eccentric protrusion 32 on the side away from the actuating part 33 is greater than the thickness on the side of the actuating part 33, the contact between the eccentric protrusion 32 and the clamped object gradually increases during the clockwise rotation of the movable part 3, and the extrusion force of the eccentric protrusion 32 on the clamped object is also increased. Under the relative action of the downward extrusion force of the eccentric protrusion 32 and the upward supporting force of the boss 11, the clamped object is tightly clamped between the movable part 3 and the boss 11, thereby realizing the locking of the clamped object by the movable part 3.

[0036] In addition, taking the direction shown in Figure 5 as an example, when the actuating part 33 is vertically downward, the distance between the movable part 3 and the boss 11 is less than the thickness of the clamped object, at this time, the locking device is in a locked state, which facilitates the clamped object to be placed between the movable part 3 and the boss 11, thereby realizing the unlocking of the clamped object by the movable part 3.In the shown direction, the movable element 3 and the clamped object are extruded to each other during the rotation of the movable element 3, so that the movable element 3 generates upward extrusion force on the elastic body 4, the elastic body 4 is extruded to deform, under the elastic characteristics of the elastic body 4 automatically recovering the deformation, the elastic body 4 provides downward support for the movable element 3, pushes the movable element 3 to move downward, under the double downward pressure of the elastic body 4 and the eccentric convex part 32, the fastening force of the movable element 3 on the clamped object is increased, the locking effect of the movable element 3 on the clamped object is enhanced, and the continuous elastic force of the elastic body 4 enables the elastic body 4 to continuously apply pre-tightening force on the movable element 3, so as to ensure that the clamped object remains stable in the locked state and is not easy to loosen, which is beneficial to realize long-time stable locking of the clamped object.

[0037] When it is needed to take out the clamped object, the eccentric convex part 32 is rotated clockwise, the movable element 3 is moved downward, the elastic body 4 is extruded to deform, and the clamped object is released from the locking device. Figure 5 In the shown direction, the movable element 3 and the clamped object are extruded to each other during the rotation of the movable element 3, so that the movable element 3 generates upward extrusion force on the elastic body 4, the elastic body 4 is extruded to deform, under the elastic characteristics of the elastic body 4 automatically recovering the deformation, the elastic body 4 provides downward support for the movable element 3, pushes the movable element 3 to move downward, under the double downward pressure of the elastic body 4 and the eccentric convex part 32, the fastening force of the movable element 3 on the clamped object is increased, the locking effect of the movable element 3 on the clamped object is enhanced, and the continuous elastic force of the elastic body 4 enables the elastic body 4 to continuously apply pre-tightening force on the movable element 3, so as to ensure that the clamped object remains stable in the locked state and is not easy to loosen, which is beneficial to realize long-time stable locking of the clamped object.
