Description

Technical Field

[0001] The utility model relates to the technical field of porcelain crucibles, in particular to a round porcelain crucible fixer. Background Art

[0002] Porcelain crucible is a chemical laboratory item. Its main components are alumina (45-55%) and silicon dioxide. It can withstand temperatures up to 1200 degrees Celsius and is suitable for melting samples of acidic substances such as K2S2O7. Porcelain crucibles come in many shapes, and round-bottomed porcelain crucibles are also more common.

[0003] The round-bottomed porcelain crucible is difficult to place stably due to its curved bottom. A fixing frame needs to be designed to fix the round-bottomed porcelain crucible, and the fixing frame is made of high-temperature resistant material to ensure normal use in high-temperature environments.

[0004] For example, a round-bottomed porcelain crucible holder disclosed in announcement number CN216630915U has a heat-insulating layer, which plays a heat-insulating role and avoids the problem of injury to workers due to poor heat insulation effect. It has a thermal insulation layer, which plays a heat-insulating role and avoids the problem of rapid heat dissipation and insufficient heat. It has a high-temperature resistant layer, which can withstand a certain high temperature and avoids the problem of being unable to withstand high temperature. Through the cooperation between the heat-insulating layer, the thermal insulation layer and the high-temperature resistant layer, it can withstand high temperatures while avoiding burns to workers.

[0005] However, the device cannot fix round-bottomed porcelain crucibles of different sizes during use, and its use is relatively limited and its practicality is low.

[0006] For this reason we urgently need to provide a kind of round porcelain crucible holder. Utility Model Content

[0009] The adjusting unit is arranged on the top of the bottom plate, the clamping unit is arranged on the right side of the bottom plate, and the limiting unit is arranged on the front and rear sides of the bottom plate.

[0010] The adjustment unit includes an adjustment disk, an adjustment rod, a moving block, a curved plate, a tooth block and a handle. The adjustment disk is installed on the top of the base plate, the adjustment rod is installed around the inside of the adjustment disk, the moving block is fixedly installed on the bottom of the adjustment rod, the curved plate is fixedly installed on the top of the adjustment rod, the tooth block is fixedly installed on the outer surface of the adjustment disk, and the handle is fixedly installed on the left side of the adjustment disk.

[0011] Preferably, an arc-shaped through groove is provided on the upper surface of the adjusting disk, and the diameter of the arc-shaped through groove is equal to the diameter of the adjusting rod. A limiting groove is provided on the upper surface of the bottom plate, and the width of the limiting groove is equal to the width of the moving block. The adjusting disk is rotated by pushing the handle, thereby pushing the adjusting rod to move in a straight line along the limiting groove through the moving block, thereby adjusting the distance between the four arc plates, and further fixing porcelain crucibles of different sizes.

[0012] Preferably, the clamping unit includes a side plate, a spring, a latch and a pull rod, the side plate is fixedly installed on the right side of the base plate, the spring is fixedly installed on the left side of the side plate, the latch is fixedly installed on the left side of the spring, and the pull rod is fixedly installed on the right side of the latch and extends to the outside of the side plate.

[0013] Preferably, the tooth grooves and the latching teeth between two adjacent tooth blocks are equal in size, and the adjusting disk is fixed by the latching teeth and the tooth grooves.

[0014] Preferably, the limiting unit includes a bracket and a pressure wheel, the bracket is fixedly installed on the front and rear sides of the base plate, and the pressure wheel is rotatably connected to the inside of the bracket.

[0015] Preferably, an annular groove is provided on the upper surface of the adjusting disk, and the lower end of the pressure wheel is located in the annular groove. The pressure wheel limits the rotation of the adjusting disk, so that the adjusting disk rotates around the pressure wheel. At the same time, the pressure wheel presses the adjusting disk to prevent the adjusting disk from jumping up and down.

[0016] Preferably, a windshield is fixedly installed on the middle part of the top of the regulating disk, and the combustion source is placed in the windshield to heat the porcelain crucible, thereby preventing the external environment from affecting the combustion source.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. This round porcelain crucible holder is provided with an adjustment unit. Pushing the handle drives the adjustment disk to rotate. When the adjustment disk rotates, the adjustment rod is driven to move linearly along the limit groove provided in the bottom plate through the moving block, thereby adjusting the distance between the four arc-shaped plates, and then fixing porcelain crucibles of different sizes. This solves the problem raised in the background art that round-bottom porcelain crucibles of different sizes cannot be fixed during use, which is relatively limited in use and has low practicality.

[0019] 2. The circular porcelain crucible holder is provided with a clamping unit, which engages the teeth with the tooth grooves between two adjacent tooth blocks to fix the adjustment disk, thereby preventing the adjustment disk from rotating when supporting the porcelain crucible.
