Description
Technical Field
[0001] The utility model belongs to the technical field of glass instruments, and particularly relates to a hoop-free ground-mouth connection structure. Background Art
[0002] The ground joints of glass instruments often have the following problems: 1) The ground joints are not sealed. When the pressure in the container changes due to the reaction, the ground joints are prone to leakage, and even cause the ground joints to separate due to pressure; 2) There are also several common situations in which the ground joints are limited by limiting structures. For example, the use of elastic clips such as clamps or clips to fix them, although the separation of the ground joints is limited to a certain extent, the limiting capacity is limited because these elastic clips are often fixed on the smooth outer walls of the upper and lower parts of the ground joints. The elastic clips themselves are prone to shift along the smooth outer walls or even fall off.
[0003] In order to solve the problem that the elastic clamp is easy to slide and deviate on the smooth outer wall of the upper and lower parts of the ground mouth connection, it is possible to consider processing the upper and lower parts of the ground mouth of the glass instrument, such as adding a limit structure to prevent the elastic clamp from sliding. However, this method increases the processing cost and is not applicable to the standard ground mouth of glass instruments on the market. Utility Model Content

[0006] Furthermore, the inner locking ring is composed of a plurality of inner locking ring pieces; the inner locking ring pieces are arc-shaped elastic parts, and the plurality of inner locking ring pieces are wrapped around the ground outer wall of the glass, and a gap is left between two adjacent inner locking ring pieces.
[0007] Furthermore, a hand-held end of an outer locking ring protruding outward is provided in the middle of the outer locking ring.
[0008] Furthermore, the clamping structure includes a lower screw cover and an elastic buckle; the cover surface of the lower screw cover is provided with a hole, the upper ground edge of the glass passes through the hole of the cover surface of the lower screw cover, and the lower screw cover is sleeved on the outer side of the lower part of the outer locking ring, and the lower part of the outer locking ring is threadedly connected to the lower screw cover; the outer wall of the lower screw cover is provided with a lower screw cover slot, and the elastic buckle respectively clamps the lower screw cover slot and the lower ground edge limiting part to realize the locking connection between the upper ground edge of the glass and the lower ground edge of the glass.

[0010] Furthermore, a plurality of anti-slip keys are arranged on the inner wall of the outer locking ring, and the anti-slip keys are located exactly between the gaps between two adjacent inner locking ring pieces.

[0012] Furthermore, a retreat groove is provided on the end surface of the lower rotary cover adjacent to the upper rotary cover, and when the upper rotary cover and the lower rotary cover are respectively matched with the two end threads of the outer locking ring, the end surface of the upper rotary cover adjacent to the lower rotary cover can enter the retreat groove.
[0013] Furthermore, the clamping structure includes a lower screw cover and an elastic buckle; two pin-connecting holes are arranged on the hole wall of the lower screw cover, and the connecting line of the two pin-connecting holes passes through the center line of the lower screw cover. Both ends of the elastic buckle are pinned into the pin-connecting holes, and the elastic buckle can be axially rotated along the connecting line of the pin-connecting holes, and the clamping end of the elastic buckle can clamp the lower ground edge of the glass.
[0014] The advantages and beneficial effects of the utility model are:

[0019] 5) The hoopless ground-joint connection structure can be applied not only to the connection between the upper ground-joint and the lower ground-joint of glass, but also to the connection between two ordinary pipe fittings. BRIEF DESCRIPTION OF THE DRAWINGS
