In order to facilitate screwing the two fixing members 10, optionally, referring to fig. 1, the insulated parallel groove clamp further includes a first sleeve 81 sleeved on one of the fixing members 10 and a second sleeve 82 sleeved on the other fixing member 10, where the first sleeve 81 and the second sleeve 82 are respectively used for driving the two fixing members 10 to rotate.
In this embodiment, the insulated parallel groove clamp further includes a locking mechanism 90, the locking mechanism 90 being configured to lock the first and second sleeves 81, 82 and unlock the first and second sleeves 81, 82 when the first and second clamps 40, 50 are driven toward each other. By arranging the locking mechanism 90, the first sleeve 81 and the second sleeve 82 can be locked when rotation is not needed, and unlocked when rotation is needed, so that the first sleeve 81 and the second sleeve 82 can keep consistent directions when rotating, and relative rotation of the first sleeve 81 and the second sleeve 82 due to external factors (such as vibration) is avoided.
Referring to fig. 4 and fig. 5, optionally, a first accommodating hole and a second accommodating hole communicated with the first accommodating hole are formed in the first sleeve 81, a boss 821 is formed on one side of the second sleeve 82 close to the first sleeve 81, and the locking mechanism 90 includes a first return spring 91 and a top ball 92 which are arranged in the first accommodating hole, an unlocking contact 93 which is arranged in the second accommodating hole, and a limit pin 94 connected with the unlocking contact 93; one side of the top bead 92 close to the unlocking contact 93 is provided with a guide opening 921, and one end of the unlocking contact 93 close to the top bead 92 is provided with a guide surface 931 matched with the guide opening 921; one surface of the first sleeve 81, which is far away from the first wire clamp 40, is provided with a waist-shaped hole 811 communicated with the second accommodating hole, and one end of the limiting pin 94, which is far away from the unlocking contact 93, penetrates through the waist-shaped hole 811; a groove 8211 is provided on one surface of the boss 821 close to the knock bead 92, the knock bead 92 can abut in the groove 8211 by the first return spring 91, the lock release contact 93 moves toward the knock bead 92, and the lock release contact can act on the guide opening 921 through the guide surface 931 to drive the knock bead 92 to compress the first return spring 91.
Referring to fig. 4, corresponding to the orientation shown in fig. 4, the first accommodating hole and the second accommodating hole are both disposed in the first sleeve 81, and the first accommodating hole is disposed along the vertical direction, and the second accommodating hole is disposed along the horizontal direction. Of course, it should be understood that the first accommodating hole and the second accommodating hole are vertically disposed only as an example of the present application, and are not limited to the present application, in other embodiments, the first accommodating hole and the second accommodating hole may also be disposed at an included angle, as long as the first accommodating hole and the second accommodating hole can be communicated, and the unlocking contact 93 located in the second accommodating hole can act on the top bead 92 in the first accommodating hole to drive the top bead 92 to move upward to separate from the groove 8211 when unlocking is required.
In this embodiment, one end of the unlocking contact 93 faces the guide opening 921 of the top bead 92, and the other end is exposed from the inner hole of the first sleeve 81. The limit pin 94 is connected to the unlocking contact 93 in order to prevent the unlocking contact 93 from falling out of the inner bore of the first sleeve 81.
Also, the waist-shaped hole 811 is provided because the unlocking contact 93 needs to move toward or away from the top ball 92 in the second receiving hole, and therefore the waist-shaped hole 811 for avoiding the position of the stopper pin 94 is provided for avoiding interference.
Optionally, the locking mechanism 90 further includes a second return spring 95 sleeved on the unlocking contact 93. The provision of the second return spring 95 enables the unlocking contact 93 to be quickly returned. Of course, the first return spring 91 may be provided to quickly return the top ball 92.
The locking mechanism 90 operates as follows: when the first sleeve 81 and the second sleeve 82 do not need to be rotated, the first sleeve 81 is rotated to enable the top bead 92 to slide into the groove 8211 of the second sleeve 82, so that the first sleeve 81 and the second sleeve 82 are mutually locked, and under the interaction of the top bead 92 and the groove 8211 of the second sleeve 82, the first sleeve 81 and the second sleeve 82 cannot be relatively rotated due to external factors such as vibration and the like, so that the directions of the first sleeve 81 and the second sleeve 82 are inconsistent; when two fixing pieces 10 need to be screwed, after a screwing tool is simultaneously inserted into the first sleeve 81 and the second sleeve 82, the screwing tool touches one end, far away from the top bead 92, of the unlocking contact 93 in the first sleeve 81 to drive the unlocking contact 93 to move towards the top bead 92 (at the moment, the second return spring 95 compresses and stores energy), and then the guide surface 931 of the unlocking contact 93 acts on the guide opening 921 of the top bead 92 to drive the top bead 92 to move upwards (at the moment, the first return spring 91 compresses and stores energy), so that the top bead 92 is separated from the groove 8211, and at the moment, the normal rotation of the first sleeve 81 and the second sleeve 82 cannot be influenced; when the fixing member 10 is screwed, and the tightening tool is disengaged from the first sleeve 81, the unlocking contact 93 is reset by the second reset spring 95, and the top bead 92 is reset by the first reset spring 91 and slides into the groove 8211.
In addition, if the top ball 92 protrudes from the first receiving hole but is not clamped in the groove 8211 of the boss 821, the unlocking contact 93 may be driven to move toward the top ball 92 so as to retract the top ball 92, then the second sleeve 82 is rotated to a proper position, and then the unlocking contact 93 is released so as to allow the top ball 92 to be clamped in the groove 8211 again under the action of the first return spring 91.
Referring to fig. 1 and 5, optionally, four corners of a side of the first wire clamp 40 facing away from the second wire clamp 50 are provided with rounded chamfers 41. This application is easily made a limit to the card department with first fastener 40 and is cut down into the fillet as much as possible, like this, can avoid first fastener 40 and spacing joint instrument to take place to make a limit to the card.
Illustratively, the fillet range of the round chamfer 41 is between R95mm and R105 mm.
