Detailed Description

To further illustrate the technical means and effects of the present invention adopted to achieve the intended purpose of the present invention, the following detailed description is given to the embodiments, structures, features and effects according to the present invention with reference to the accompanying drawings and preferred embodiments as follows:

example 1

As shown in fig. 1, a fixture comprises a housing 1 and at least one set of clamping jaws 2, wherein the set of clamping jaws 2 comprises two symmetrically arranged clamping jaws 2, a first groove 11 is formed in the housing 1, an opening of the first groove 11 faces forward, the clamping jaws 2 are installed on the fixture, and the clamping jaws 2 are used for clamping objects in the first groove 11. It should be understood that the housing 1 is sealed at other positions than the opening to prevent iron sand from splashing out of the housing 1 and injuring the experimenter. It will be appreciated that the housing 1 is of a sealed construction at a location other than the first recess to avoid splashing of sand out of the opening of the first recess.

More preferably, as shown in fig. 2, the housing includes a left side surface, a right side surface, a back surface, a top surface and a bottom surface which are connected in sequence, and the left side surface, the right side surface, the back surface, the top surface and the bottom surface form a sealed structure, and a first groove is formed on the front surface. Avoid grit to get into the back from the opening of first recess through above-mentioned structure, splash away, can only remain in first recess or flow fall back in the stone crusher.

In one possible embodiment, the clamping jaw 2 is slidably or rotatably mounted on the housing 1, preferably, as shown in fig. 5, the clamping jaw 2 includes a handle 21, a screw 22 and a clamping portion 23, the screw 22 is rotatably connected to the housing 1, the handle 21 is disposed at one end of the screw 22 and located outside the first groove 11, and the clamping portion 23 is disposed at the other end of the screw 22 and located inside the first groove 11; more preferably, the screw 22 is screwed to the housing 1. More specifically, as shown in fig. 3 and 4, the housing 1 is provided with a threaded hole 12 matched with the screw 22, and the front and back movement of the clamping jaw is realized through the matching of the threaded hole 12 and the screw 22.

In one possible embodiment, in order to make the clamping portion 23 have a shape after being rotated, thereby ensuring stable clamping, the cross section of the clamping portion 23 is preferably circular, and preferably, the clamping portion 23 is cylindrical. More precisely, the clamping portion 23 is of a flat cylindrical shape. More precisely, the clamping surface of the clamping portion 23 is circular and the screw 22 is perpendicular to the clamping surface. In one embodiment, the clamping jaw 2 includes a socket head cap and a clamping portion 23, as shown in fig. 8, the socket head cap includes a screw head and a rod body, the screw head corresponds to the handle 21 (shank), the rod body corresponds to the screw rod 22, and a threaded inner cavity is formed in the rod body, as shown in fig. 9, the clamping portion 23 is provided with a fixing rod, and the clamping portion 23 is fixed on the socket head cap through the matching of the fixing rod and the threaded cavity, and the distance between the fixing rod and the threaded inner cavity can be adjusted.

In one possible embodiment, the housing 1 is a square, spherical or hemispherical structure, and since iron sand may be continuously flown into the first recess 11 from the rock crusher and hit the housing 1 and the object (part) held in the first recess 11, the user is required to provide a constant pressure to press the clamp to keep the clamp from moving. Thus, the clip is preferably square to facilitate the user holding the clip against movement with both or one hand to assist or press the clip.

In one possible embodiment, the iron sand flying out can be returned to the lithotripter without remaining in the first groove 11, as shown in fig. 7, the bottom surface of the first groove 11 extends downward from back to front; because under most circumstances, shell 1 and first recess 11 in the anchor clamps are along the structure of center pin longitudinal symmetry, so for the convenience of customers' use, the top surface of first recess 11 extends from back to front upwards for no matter the user normally places or transfers the anchor clamps to place on the stone crusher, the iron sand of first recess 11 bottom also can be followed the bottom surface and slided down to the stone crusher in.

In one possible embodiment, the clamp further comprises a plurality of sets of clamping jaws 2, and a set of two clamping jaws 2 are respectively arranged on the left side and the right side, or on the upper side and the lower side of the shell 1. In this embodiment, the stable clamping of the articles (parts) with different sizes and shapes is realized by adding a plurality of groups of clamping jaws 2, so that the applicability of the embodiment is improved. It should be understood that although the clamping jaws 2 are disposed on the left and right sides of the housing 1 in the drawings of the present embodiment, several sets of clamping jaws may be disposed on the left and right sides of the housing, and several other sets of clamping jaws may be disposed on the upper and lower sides of the housing. It will be appreciated that two sets of jaws may be provided on either side of the housing, but one set is located in front of the other, to facilitate gripping of different shaped articles by the jaws.

In one possible embodiment, the shell 1 is made of a transparent material, so that workers can see the first groove conveniently.

In one possible embodiment, the first groove 11 is provided with scales, so that a worker can repeatedly simulate the same experimental environment.

In one possible embodiment, as shown in fig. 12, the housing 1 is provided with a rubber 14, preferably, the front surface of the housing 1 is provided with the rubber 14, the rubber 14 surrounds the first groove 11, and more precisely, the rubber 14 is arranged on the outer edge of the front surface of the housing 1. In order to provide a better fit of the housing 1 on the rock crusher and to avoid rock escape from the gap between the clamp and the rock crusher, a thin layer of rubber 14 may be provided on the front surface of the housing 1.

Example 2

Different from embodiment 1, sometimes, because the careless clamping jaw 2 of the experimenter does not completely abut on the object (part) during iron sand impact or installation, the position of the object is changed for a long time when the experiment starts, and the test effect cannot be achieved (the iron sand cannot be touched on a certain surface of the part or is very difficult to touch on the certain surface of the part), as shown in fig. 10 and 11, the back surface of the housing 1 is provided with an observation window, the observation window extends from the back surface of the housing 1 to the back surface of the first groove 11 (i.e. the back surface of the housing penetrates through the front and back of the observation window), the observation window is provided with a window assembly 13, the window assembly 13 is fixed at the observation window in a sealing manner, the window assembly is used for sealing the observation window, and meanwhile, a user can see the object in the first groove 11 from the outside of the housing 1 through the window. Therefore, the user can find the offset condition of the object (part) at the beginning of the experiment, stop the experiment in advance and avoid error data.

Preferably, the window assembly 13 is made of transparent rigid plastic (although rigid plastic such as PC transparent plastic has certain hardness, but has general wear resistance and is easily worn by iron sand), and the most preferable material is CR 39, MR 8, J.D, CR330 or MR 174.
