Abstract
Description
Technical Field
[0001] The invention relates to the technical field of glass instruments, and in particular to a ground-joint structure and an installation and disassembly method. 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. Summary of the invention
[0003] The object of the present invention is to provide a ground-joint clamping structure and an installation and disassembly method, through which the ground-joint clamping structure can realize rapid connection and disassembly between ground joints, while ensuring stable connection between ground joints and improving airtightness and safety to a certain extent.
[0004] In order to achieve the above-mentioned purpose, the technical solution of the present invention is to design a ground-mouth clamping structure, including an upper ground mouth, a lower ground mouth, a connecting sleeve, a connecting cover and an elastic clamp; the ground mouth portion of the upper ground mouth can be inserted into the ground mouth portion of the lower ground mouth, and the connecting sleeve and the rear end outer wall of the ground mouth portion of the upper ground mouth are provided with a combined limiting structure to ensure that the connecting sleeve cannot be separated from the rear end outer wall of the ground mouth portion of the upper ground mouth when the connecting sleeve is sleeved on the rear end outer wall of the ground mouth portion of the upper ground mouth; the front end outer wall of the ground mouth portion of the lower ground mouth is provided with a lower ground mouth limit; a connecting cover through hole is provided on the cover surface of the connecting cover; an elastic clamp is hinged on the side wall of the connecting cover, and the elastic clamp can rotate along the hinged end of the elastic clamp; the connecting sleeve and the connecting cover are threadedly connected.
[0005] Furthermore, the combined limiting structure includes an upper ground mouth limiter, an elastic card and a first limiting step; the upper ground mouth limiter is arranged on the outer wall at the rear end of the ground mouth portion of the upper ground mouth; a plurality of elastic card grooves are arranged on the upper side wall of the connecting sleeve, and an elastic card that pops out inward is arranged in the elastic card groove; the first limiting step is arranged on the inner wall of the connecting sleeve, and a space for inserting the upper ground mouth limiter is provided between the elastic card and the first limiting step.
[0006] Furthermore, a plurality of auxiliary disassembly grooves are provided on the upper side wall of the connecting sleeve near the elastic clamping groove.
[0007] Furthermore, the lower edge of the upper portion of the connecting sleeve extends outward to form a first limit; and a second limit step is provided on the inner wall of the connecting cover above the internal thread.
[0008] Further, an "L"-shaped clamping groove is provided on the outer wall of the connecting cover. When the elastic clamp rotates to the horizontal and vertical angles, the outer wall of the elastic clamp can be embedded in the "L"-shaped clamping groove.
[0009] The elastic clamp is an elastic member. In the state perpendicular or horizontal to the connecting cover, the outer wall of the elastic clamp is embedded in the "L"-shaped clamping groove. When the elastic clamp needs to be toggled, the elastic clamp undergoes elastic deformation, enabling the elastic clamp to flip. After returning to the position where the "L"-shaped clamping groove is located, the elastic clamp returns to its original state and is embedded in the "L"-shaped clamping groove.
[0010] Further, the upper ground joint limiting section is non-circular, and the inner wall of the connecting sleeve matches the upper ground joint limit, ensuring that the upper ground joint limit can only enter and exit the connecting sleeve in a specific orientation.
[0011] Through the above design of the connecting sleeve and the upper ground joint limit, it can be ensured that the upper ground joint limit cannot rotate horizontally within the connecting sleeve.
[0012] A method for installing and disassembling the upper ground joint and the lower ground joint using a ground joint clamping structure includes the following steps:
[0013] Step 1: During installation, the connecting sleeve is sleeved on the rear end of the ground joint part of the upper ground joint, and the upper ground joint limit is restricted between the elastic clamp and the first limiting step;
[0014] Step 2: Thread the connecting cover to the connecting sleeve. The first limit and the second limiting step can limit the maximum distance that the connecting sleeve can be screwed into the connecting cover; the ground joint part of the upper ground joint passes through the through-hole of the connecting cover;
[0015] Step 3: Insert the ground joint part of the upper ground joint into the ground joint part of the lower ground joint. The elastic clamp clamps the lower ground joint limit of the lower ground joint, forming a relatively stable connection between the upper ground joint and the lower ground joint. In this state, the outer wall of the elastic clamp can be embedded in the "L"-shaped clamping groove, ensuring that the elastic clamp will not disengage from the lower ground joint limit without being manually toggled;
[0016] Step 4: During disassembly, toggle the elastic clamp to disengage the elastic clamp from the lower ground joint limit and remove the lower ground joint;
[0017] Step 5: Unscrew the connecting cover from the connecting sleeve;
[0018] Step 6: Use tools such as a screwdriver to assist in pushing the elastic clamp into the elastic clamping groove, canceling the restriction of the elastic clamp on the upper ground joint limit, and then remove the connecting sleeve along the direction of the ground joint part of the upper ground joint; during this process, tools such as a screwdriver can penetrate into the gap between the elastic clamp and the upper ground joint through the disassembly auxiliary groove.
[0019] The advantages and beneficial effects of the present invention are as follows:
[0020] 1) The connecting sleeve and the upper ground joint are stably connected by a snap - limit connection method; the connection between the connecting sleeve and the connecting cover is achieved by a threaded connection method, and finally the lower ground joint is clamped by an elastic clamp, so as to realize the stable connection between the upper ground joint and the lower ground joint.
[0021] 2) During the repeated installation and disassembly of the upper ground joint and the lower ground joint, the connecting sleeve and the upper ground joint do not need to be disassembled, which can be achieved only by flipping the elastic clamp, making the installation and disassembly of this structure faster during use.
[0022] 3) When the connecting cover needs to be replaced, just screw the connecting cover off the connecting sleeve. When the connecting sleeve needs to be replaced, a tool can be used to push the elastic card into the elastic card slot, and then the connecting sleeve can be removed from the upper ground joint.
