Description

Technical Field

[0001] The utility model relates to the technical field of fixing jigs, in particular to a novel double-rod cross chuck. Background Technique

[0002] During the R & D experiment process, an iron stand is a commonly used fixing tool, and it can be extended through a cross chuck to stably fix and clamp various experimental equipment.

[0003] The existing connection method between the cross chuck and the support vertical rod is generally fixed by tightening with the cooperation of a slotted hole and a bolt. The contact area between the support vertical rod and the chuck is small, which easily leads to loose tightening, inclination, or even detachment of the cross chuck from the support vertical rod; another connection method is to install through a through hole preset with a corresponding size of the support vertical rod, and at the same time, a through groove connected to the through hole is opened, and the size of the through groove is adjusted by a bolt to achieve clamping of the support vertical rod. However, the support vertical rod must match the through hole, and the versatility is general; in addition, the horizontal rods of the existing chucks are mostly set in a single group, and the support stability for larger equipment during actual use is relatively general. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is that the connection method between the existing cross chuck and the support vertical rod has general stability, is not flexible and convenient to use, and the horizontal rods of the existing cross chucks are mostly set in a single group, and the support stability for larger equipment is general.

[0005] To solve the above technical problems, the utility model provides the following technical solutions: A novel double-rod cross chuck proposed by the utility model includes a chuck, a support vertical rod, a support horizontal rod, and an auxiliary horizontal rod. Cross bar fixing grooves and vertical rod fixing grooves are respectively arranged on both sides of the chuck. The cross bar fixing grooves and the vertical rod fixing grooves are located on both sides of the chuck and are perpendicular to each other. A cross bar handle seat is arranged on one side of the cross bar fixing groove, and a vertical rod handle seat is arranged on one side of the vertical rod fixing groove. A first tightening bolt passes through and is threadedly connected to the cross bar handle seat, and a second tightening bolt passes through and is threadedly connected to the vertical rod handle seat. A through hole is also arranged on the chuck, and the through hole penetrates the vertical rod fixing groove. The support vertical rod is slidably arranged in the vertical rod fixing groove and is fixed by pressing with the second tightening bolt. The support horizontal rod is slidably arranged in the cross bar fixing groove and is fixed by pressing with the first tightening bolt. The auxiliary horizontal rod penetrates and slides in the through hole, and one end penetrates the vertical rod fixing groove. The support horizontal rod is arranged parallel to the auxiliary horizontal rod, greatly increasing the support stability for larger equipment.

[0006] Preferred Technical Solution 1: The cross bar fixing groove is arranged in a U-shaped structure, and the center line of the second tightening bolt coincides with the bottom right-angle bisector of the cross bar fixing groove, and the pressing force acts perpendicularly on the support horizontal rod.

[0007] Preferred Technical Solution 2: The vertical rod fixing groove is arranged in an L-shaped structure, and one end of the vertical rod fixing groove is arranged in an arc shape. The supporting vertical rod is stably pressed by a pair of tightening bolts. The pressing force acts vertically on the supporting vertical rod, making the contact between the supporting vertical rod and the bottom wall and side wall in the vertical rod fixing groove more stable, increasing the connection stability of the chuck and avoiding tilting and falling off.

[0008] Preferred Technical Solution 3: Adjusting knobs are further provided at the other ends of the first tightening bolt and the second tightening bolt.

[0009] For a new type of double-rod cross chuck proposed by the present utility model, the beneficial effects obtained by adopting the above structure are as follows:

[0010] (1) The cross bar fixing groove and the vertical rod fixing groove are provided on the chuck. The center line of the first tightening bolt coincides with the bottom right-angle bisector of the cross bar fixing groove, and the pressing force acts vertically on the supporting cross bar, with uniform force application; the supporting vertical rod cooperates with the vertical rod fixing groove and is tightened by the second tightening bolt, and the contact with the cross bar fixing groove and the vertical rod fixing groove is more stable respectively, increasing the connection stability of the chuck and avoiding tilting and falling off;

[0011] (2) The through holes and the auxiliary cross bars are provided to cooperate to increase the number of cross bars and improve the supporting stability for larger appliances. Description of the Drawings
