Detailed Description

The utility model is further described with reference to the following drawings and detailed description.

As shown in fig. 1 to 3, an elastic snap ring for organic chemical reaction comprises an elastic ring body 1 and an elastic hook 2 arranged on the outer side surface of the ring body 1, wherein the ring body 1 is C-shaped, the two opposite surfaces of the free ends of the ring body 1 are horizontally arranged, the end surfaces of the two opposite surfaces are provided with first fillets 11, the first fillets 11 are convenient for the smooth deformation of the ring body 1 when the ring body 1 is inserted into an instrument tube, the inner annular surface of the ring body 1 is uniformly and alternately provided with a plurality of ribs 12, the ribs 12 are used for contacting with the instrument tube, when the hook 21 is in a hooked state, the ribs near the root of the hook 2 are more closely contacted with the instrument tube, the friction between the ring body 1 and the instrument tube is increased by the way of deforming the ring body 1, the number of the hooks 2 is not less than two, the hooks are preferably symmetrically arranged or uniformly distributed, the free ends of the hooks 2 are provided with the hook 21, the outer end surface of the hook 21 is provided with a second fillet 22, the second fillet 22 is convenient for the smooth deformation of the hook 2, the adjacent two ribs 12 and the inner annular surface of the ring body 1 enclose a deformation groove 13, the ribs 12 increase the axial rigidity of the ring body 1, the deformation groove 13 increases the radial elasticity of the ring body 1, and the inner end surface of the hook head 21 and the inner surface of the hook 2 enclose an arched elastic surface 23 to provide tension for the hook head 21.

Further, in order to facilitate the hook head 21 to be clamped and smoothly clamped, the minimum distance from the end part of the hook head 21 to the center of the ring body 1 is not less than the inner radius of the ring body 1.

As shown in fig. 4, it is further provided that, in order to increase the pulling force of the hook head 21 and to apply force uniformly, the number of the hooks 2 is preferably three and is uniformly arranged on the outer side surface of the ring body 1.

The operation method comprises the following steps: in the experimental operation, taking the connection of a condenser pipe socket 3 and a tail pipe grinding opening 4 in an ethanol distillation experiment as an example, in the first step, an elastic snap ring which is adaptive to the specification and model of an instrument interface is selected, the ring body 1 is clamped into the condenser pipe socket 3 along the arrow direction in fig. 5, and at the moment, the ribs 12 are in clearance fit with the condenser pipe socket 3 and can axially move along the condenser pipe socket 3 under the action of external force; secondly, pushing the ring body 1 in the arrow direction in fig. 6, when the ring body 1 is close to the grinding opening 4 of the tail connecting pipe, the hook head 21 slides along the contour of the bulge 5 on the outer edge of the grinding opening, and the hook 2 deforms; and step three, as shown in fig. 7, the ring body 1 leans against the left side of the grinding opening outer edge bulge 5, the hook head 21 hooks the right side of the grinding opening outer edge bulge 5, the elastic surface 23 resists deformation to generate tensile force, and the ribs 12 near the root part of the hook 2 are further pressed on the condenser pipe socket 3, so that the connection of the condenser pipe socket 3 and the tail pipe grinding opening 4 is assisted and fixed.
