Description

TECHNICAL FIELD

[0001] The utility model relates to rock sample manufacturing technical field, especially relate to a rock slice anti -drop device. BACKGROUND

[0002] Rock slice preparation is a common experimental technique in the fields of geology and petrology, and is an important tool for observing the structure, structure, mineral composition and paragenetic relationship of rocks. The surrounding structure and mineral composition of the rock are observed. In order to better observe and analyze under the microscope, the rock slice usually needs to be ground to a thickness of only 0.03mm. First, the rock is cut into a rock piece with a length, width and thickness of about 3cm*2cm*0.6cm by a slicing machine. After one side of the rock piece is polished flat and smooth on a grinding machine, it is adhered to a glass slide with a uniform specification of length* width* thickness: 76.5mm*25.5mm*1.2mm. After the rock is firmly adhered, the rock piece adhered on the glass slide is polished, which is the key to making qualified slices. In the prior art, the rock slice on the glass slide is usually polished by a grinding machine. The grinding machine usually consists of a rack and a motor mounted on the rack to drive a horizontally arranged circular grinding disc. The rock slice on the glass slide is polished by rotating the circular grinding disc quickly by the motor. Since the grinding disc is in rapid rotation during polishing, for safety reasons, the operator is not allowed to wear gloves and can only hold the glass slide in his hand to polish the rock slice adhered to the glass slide. Since the glass slide is thin and difficult to hold, the glass slide is easy to drop on the rapidly rotating grinding disc during polishing, and the glass slide dropped on the rapidly rotating grinding disc is easy to be broken and splashed to hurt people. SUMMARY

[0003] In view of the above problems of the prior art, the technical problem to be solved by the utility model is to provide a rock slice anti-drop device to solve the problem of splashing and hurting people caused by the glass slide dropping when polishing the rock slice by hand.

[0004] To solve the above technical problems, one technical scheme of the utility model is: a rock slice anti-falling device, including an adsorption seat for adsorbing a glass slide, a fixed component connected with a grinding machine and an elastic piece one elastically connecting the adsorption seat and the fixed component, the bottom surface of the adsorption seat is concavely provided with a placing cavity matched with the glass slide, the depth of the placing cavity is less than the thickness of the glass slide, the upper surface of the adsorption seat is concavely provided with a mounting cavity, a sliding block is slidably arranged in the mounting cavity, the bottom surface of the mounting cavity is vertically provided with a slide, the lower end of the slide is communicated with the placing cavity, the mounting cavity is provided with an elastic piece two forcing the sliding block away from the bottom surface in the mounting cavity, the bottom surface of the sliding block is concavely provided with a slide column sealingly and slidably matched with the slide, the fixed component includes a fixed part arranged on the surface of the grinding machine on both sides of the grinding disc, the elastic piece one includes an elastic rope, the two ends of the elastic rope are respectively fixedly connected with a fixed part, the adsorption seat is connected with the middle part of the elastic rope, and the adsorption seat is away from the grinding disc under the elastic force of the elastic rope.

[0005] In the above scheme, when the rock slice on the glass slide is ground, the bottom surface of the sliding block is contacted with the bottom surface of the mounting cavity by pressing the sliding block, at this time, the slide column slides down to discharge the gas in the slide, then the glass slide is put into the placing cavity by making the rock slice downward, so that the glass slide is tightly attached to the bottom wall of the placing cavity, the fingers are released, the elastic piece two forces the sliding block to drive the slide column to slide upward, and the negative pressure is formed in the lower cavity of the slide, so that the glass slide is adsorbed and tightly attached to the bottom wall of the placing cavity, the adsorption seat is moved downward to make the rock slice contact the grinding disc in rotation to grind the rock slice, at this time, the elastic rope is stretched, the sliding block and the upper surface of the adsorption seat are pressed downward to apply pressure downward, so that the rock slice can be ground by moving on the grinding disc, at this time, the glass slide cannot move transversely to separate from the adsorption seat under the limitation of the side walls of the placing cavity. When the adsorption seat is separated from the operator by accident during the grinding process, the elastic rope pulls the adsorption seat upward to prevent the adsorption seat from falling to contact the grinding disc in rotation, so that the glass slide with the rock slice is prevented from being hit by the grinding disc in rotation.

[0006] Further, the inner cavity of the slide and the space outside the adsorption seat are communicated through a gas discharge channel, and a blocking part is detachably connected to the outer port of the gas discharge channel.

[0010] Further, the elastic rope is provided with two elastic ropes arranged horizontally and in parallel. The horizontal and parallel arrangement of the two elastic ropes prevents the adsorption seat from rotating when the rock slice is dropped, thereby preventing the adsorption seat from being thrown off the slide glass.

[0011] Further, the two opposite side walls of the adsorption seat are respectively provided with a sliding groove in sliding fit with the elastic rope along the length direction of the elastic rope, and the adsorption seat is detachably connected with a blocking mechanism for preventing the elastic rope from being separated from the sliding groove. The elastic rope is limited to slide in the sliding groove, so that the elastic rope is prevented from being separated from the adsorption seat, and meanwhile, the operator can move the adsorption seat to polish the rock slice at different positions of the grinding disc.

[0012] Further, the blocking mechanism includes a plurality of insertion grooves vertically arranged in the adsorption seat and an insertion plate inserted into the insertion grooves, and the insertion grooves are arranged close to the side wall where the sliding groove is located.

[0015] Compared with the prior art of directly holding the slide glass for polishing, the present application has at least the following beneficial effects:

[0016] 1. The adsorption seat in the present application has a thickness greater than that of the slide glass, so that the adsorption seat is convenient to hold for polishing the rock slice on the slide glass, and the fingers of the operator are effectively prevented from being scratched by the slide glass.

[0017] 2. In the present application, when the operator accidentally drops the adsorption seat from the hand during the polishing of the rock slice, the sliding block is forced to slide upward to adsorb and tightly attach the slide glass to the bottom wall of the placing cavity, and the adsorption seat moves upward under the elastic force of the elastic rope to prevent the adsorption seat from moving downward to contact the rotating grinding disc, thereby preventing the slide glass with the rock slice from being hit by the rotating grinding disc.

The bottom surface of the adsorption seat 10 has a vertically upward-recessed placement cavity 101 adapted to the glass slide 50. The bottom wall of the placement cavity 101 has intersecting adsorption grooves 1011. A rubber layer 40 is attached to the bottom wall of the placement cavity 101. The depth of the placement cavity 101 after attaching the rubber layer 40 is less than the thickness of the glass slide 50, so that the rock slice 60 adhered to the glass slide 50 is completely below the lower surface of the adsorption seat 10, allowing the rock slice 60 to be ground to any thickness. The upper surface of the adsorption seat 10 has a vertically downward-recessed mounting cavity 102. The mounting cavity 102 is a rectangular cavity located in the middle of the adsorption seat 10. A slider 103 is slidably disposed within the mounting cavity 102. A cylindrical part is vertically disposed on the bottom surface of the mounting cavity 102. The slide 104 has a blind end at its lower end. An air passage 1012 is vertically arranged inside the adsorption seat 10.
