Description
Technical Field
[0001] The utility model relates to a meter joint, in particular to a meter joint with a protective cover. Background Art
[0002] The meter joint is used to connect equipment or pipelines. There are various forms of meter joints, including welded pipe joints, expanded pipe joints, tee intermediate joints, elbow intermediate joints, straight intermediate joints, straight cone pipe joints, ferrule pipe joints, etc.
[0003] The current meter joint is easily damaged under the impact of external force, resulting in leakage at the connection, posing a safety hazard. The addition of a protective cover can effectively protect the meter joint, but the protective cover only exists in a completely locked protection state. During temporary connection, disassembly is cumbersome, affecting work efficiency. Utility Model Content
[0004] In view of the deficiencies in the prior art, the utility model aims to provide a meter connector with a protective cover and an adjustable fixing state of the protective cover.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: including a joint body, an upper protective cover and a lower protective cover, the upper protective cover and the lower protective cover have a receiving groove for receiving the joint body, including a fixing rod, an end of the fixing rod is provided with an extended elastic part along the direction of the fixing rod, and the cross-sectional area of the extended elastic part gradually increases along the direction close to the fixing rod, the extended elastic part has a pressing surface perpendicular to the fixing rod at one end relatively close to the fixing rod, and the area of the pressing surface is larger than the area of the cross-sectional area of the fixing rod, the upper protective cover and the lower protective cover are provided with a fixing hole for the fixing rod to pass through, the other end of the fixing rod relative to the extended elastic part is provided with a blocking part, and the blocking part cannot pass through the fixing hole, the fixing rod has a temporary fixing state for fixing the upper protective cover and the lower protective cover, and the lower protective cover is provided with a reinforcing fixing mechanism for fixing the fixing rod to the lower protective cover.
[0006] By adopting the above technical scheme, when only a temporary connection is needed, the two ends of the joint body are respectively connected to the corresponding components, and then the upper protective sleeve and the lower protective sleeve are sleeved on the joint body, and then the extended elastic part of the fixing rod is close to the upper protective sleeve and inserted. At this time, the extended elastic part shrinks, and the pressing surface is the same as the cross-section of the fixing rod, until the extended elastic part passes through the fixing hole and the extended elastic part returns to its original state. At this time, the pressing surface is against the lower bottom surface of the lower protective sleeve, and the fixing rod cannot be pulled back in the opposite direction, completing the temporary fixation. When it needs to be released, the extended elastic part can be manually pressed so that the extended elastic part can pass through the fixing hole to complete the unlocking. When a long-term connection is required, the fixing rod can be fixed to the lower protective sleeve by the reinforced fixing mechanism. At this time, even if the extended elastic part is pressed, the fixing rod cannot move, forming a complete fixation. The fixing effect is more stable than the temporary fixing state. Through the setting of the fixing rod and the reinforced fixing mechanism, there are two fixing methods between the upper protective sleeve and the lower protective sleeve. The corresponding fixing method can be used according to needs, and there are more application scenarios.
[0007] The utility model is further configured as follows: the enhanced fixing mechanism includes a screw rod, a moving block, a fixing spring and a locking block; the lower protective sleeve is provided with a matching hole perpendicular to the fixing hole and the matching hole extends to communicate with the fixing hole; the matching hole includes a threaded portion and a sliding portion; the threaded portion is threadedly matched with the screw rod and extends outside the matching hole; the sliding portion is located between the threaded portion and the fixing hole and is provided for the moving block and the locking block to slide; the screw rod constitutes the movement of the moving block in the sliding portion; the locking block is slidingly arranged in the sliding portion and is located on the other side of the moving block relative to the screw rod; the fixing spring is arranged between the locking block and the moving block; the fixing rod is provided with an annular groove; the locking block enters the annular groove to constitute the fixation of the lower protective sleeve and the fixing rod.
[0008] By adopting the above technical solution, when a long-term connection is required, the fixing rod temporarily fixes the upper protective cover and the lower protective cover, while the annular groove is opposite to the matching hole, and the locking block enters the annular groove under the action of the fixing spring. At this time, the fixing rod cannot move. When the fixation needs to be released, the screw rod is rotated to drive the moving block to move outward, and finally drive the locking block to move out of the annular groove, thereby releasing the fixation between the lower protective cover and the fixing rod. The fixation between the fixing rod and the lower protective cover can be adjusted by moving the screw rod, and corresponding adjustments can be made according to actual conditions.
[0009] The utility model is further configured as follows: it includes a linkage conversion member, a rotating chamber is arranged in the moving block, a connecting channel connecting the rotating chamber with the outside is arranged on the moving block, and the connecting channel is close to the screw rod, one end of the linkage conversion member is fixed to the screw rod, and the other end enters the rotating chamber through the connecting channel and cooperates with the moving block to rotate, and the linkage conversion member constitutes the screw rod to move the moving block in the sliding part.
[0010] By adopting the above technical solution, when the screw rotates, it drives the linkage conversion member to rotate, and the linkage rotating member moves, and then the linkage conversion member rotates in the conversion chamber and pushes the moving block to make corresponding movement.
[0011] The utility model is further configured as follows: the locking block has an arc-shaped end on one side relatively close to the fixing hole.
[0012] The utility model is further configured as follows: the joint body comprises an outer connecting end and an inner connecting end, a limiting ring is arranged at the end of the inner connecting end, and the upper protective sleeve and the lower protective sleeve are provided with limiting grooves matched with the limiting ring.
[0013] By adopting the above technical solution, the setting of the limiting ring and the limiting groove prevents the joint body and the protective sleeve from generating relative displacement, thereby achieving a better protective effect. BRIEF DESCRIPTION OF THE DRAWINGS
