Cross connection support of easy assembly and disassembly corrector

Abstract

This utility model discloses a cross-shaped connecting bracket for an easy-to-install and easy-to-disassemble calibrator, relating to the technical field of calibrator connecting brackets. It includes a cross-shaped body and a contact block. One side of the cross-shaped body has a circular hole a, and the other side of the circular hole a has a circular hole b. Both circular holes a and b have keyways on one side, with a locking key b slidably connected in the keyway near circular hole a. When installing a six-point calibrator connecting rod and a one-inch vertical calibrator connecting rod, the six-point calibrator connecting rod and the one-inch vertical calibrator connecting rod are inserted into circular holes b and a, respectively. Then, rotating two sets of top-pressing screws pushes the locking key b to move. When the arc surface of one side of the two sets of locking keys b abuts against the connecting rod inside circular holes a and b, the locking key b will be unable to move, thus achieving stable positioning of the two sets of connecting rods.

Description

Technical Field

[0001] This utility model relates to the technical field of calibrator connection brackets, specifically a cross-shaped connection bracket for easy-to-install and easy-to-disassemble calibrators. Background Technology

[0002] Paper machine forming wires, felt, and dry wire are generally equipped with misalignment detectors and misalignment correctors, used to detect misalignment alarms, interlock trips, and correct misalignment functions, respectively. Misalignment alarms typically use inductive proximity switches. However, due to high humidity and temperature, electronic products are prone to failure. Misalignment correction is a mechanical device, requiring the corrector baffle to be in contact with the edge of the wire or felt during operation. Furthermore, since the felt and dry wire are consumable parts of the paper machine, the position of the corrector or misalignment alarm must be readjusted after each replacement. Therefore, misalignment detectors and correctors require frequent installation and removal.

[0003] Existing deviation alarms and deviation corrector crossbars often break due to repeated disassembly and reassembly, or because they are installed in the mesh section or the pressing section is frequently cleaned with caustic soda. This can cause the metal deformation points to break, or the screws to be dented at the corrector rod, making it impossible to remove the corrector rod. Utility Model Content

[0004] The purpose of this utility model is to provide a cross-connecting bracket for easy installation and disassembly of a calibrator, so as to solve the problem of the existing cross-connecting bracket for calibrators being difficult to install and disassemble as mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cross-shaped connecting bracket for an easy-to-install and easy-to-disassemble calibrator, comprising a cross-shaped body and a contact block, wherein a circular hole a is provided on one side of the cross-shaped body, and a circular hole b is provided on the other side of the circular hole a; a keyway is provided on one side of both the circular hole a and the circular hole b, wherein a locking key b is slidably connected in the keyway near the circular hole a, and a locking key a is slidably connected in the keyway near the circular hole b; both ends of the cross-shaped body are threadedly connected to a pressing screw; a handle is rotatably connected to one end of the pressing screw, and a locking mechanism is provided inside the handle.

[0006] Furthermore, the end of the top-pressing screw away from the handle is rotatably connected to an abutment block via a rotating shaft, and both ends of the locking key a and locking key b are integrally formed with protrusions, and the protrusions have through holes inside.

[0007] Furthermore, both lock key a and lock key b have an arc-shaped groove on one side, and the diameter of the arc-shaped groove on the side of lock key a is smaller than the diameter of the arc-shaped groove on the side of lock key b.

[0008] Furthermore, the engaging mechanism includes an annular groove formed on the outside of the pressing screw, and a limiting ring is rotatably connected to the outside of the annular groove, the outside of which is fixed to the handle.

[0009] Furthermore, the end of the top-pressing screw away from the abutment block has multiple sets of slots, and a locking block is fixedly connected to the inner side of the handle, with the width of the slots being greater than the thickness of the locking block.

[0010] Furthermore, one end of the pressing screw abuts against a spring, and one end of the spring abuts against the inside of the handle.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. The cross-shaped connecting bracket of this easy-to-install and easy-to-disassemble corrector, when installing the six-point corrector connecting rod and the one-inch vertical corrector connecting rod, is installed by inserting the six-point corrector connecting rod and the one-inch vertical corrector connecting rod into the round hole b and the round hole a respectively, and then rotating the two sets of top pressing screws to push the locking key b to move. When the arc surface of one side of the two sets of locking keys b abuts against the connecting rod inside the round hole a and the round hole b, the locking key b will be unable to move, thus completing the stable limiting of the two sets of connecting rods. In this way, the connecting rods inside the cross body can be easily installed and disassembled through the above operation.

[0013] 2. The cross-shaped connecting bracket of this easy-to-install and easy-to-disassemble calibrator allows the handle to be released after the connecting bracket inside the cross body is installed. The spring will push the handle to reset, causing the locking block inside the handle to disengage from the locking slot. Therefore, if the handle is accidentally turned at this time, the handle will not drive the abutment block to rotate, thereby preventing the locking key b from disengaging from the clamping limit on the connecting rod. In this way, the above operation can facilitate the protection against accidental contact of the top pressure screw. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: Please refer to Figures 1-6 This utility model provides the following technical solution: a cross-shaped connecting bracket for an easy-to-install and easy-to-disassemble calibrator, including a cross-shaped body 1 and abutment block 9. A circular hole a2 is provided on one side of the cross-shaped body 1, and a circular hole b3 is provided on the other side of the circular hole a2. A keyway 7 is provided on one side of both the circular hole a2 and the circular hole b3. A locking key b5 is slidably connected in the keyway 7 near the circular hole a2, and a locking key a4 is slidably connected in the keyway 7 near the circular hole b3. Both ends of the cross-shaped body 1 are threadedly connected to a pressing screw 8. The end of the pressing screw 8 away from the handle 10 is rotatably connected to the abutment block 9 through a rotating shaft. Both ends of the locking key a4 and the locking key b5 are integrally formed with a protrusion, and the protrusion has a through hole 6 inside. The abutment block 9 forms a rotating structure with the pressing screw 8 through the rotating shaft, and the pressing screw 8 forms a threaded transmission structure with the cross-shaped body 1. An arc-shaped groove is provided on one side of both the locking key a4 and the locking key b5, and the diameter of the arc-shaped groove on the side of the locking key a4 is smaller than the diameter of the arc-shaped groove on the side of the locking key b5.

[0023] When installing the six-point corrector connecting rod and the one-inch vertical corrector connecting rod, insert the six-point corrector connecting rod and the one-inch vertical corrector connecting rod into the round hole b3 and the round hole a2 respectively. Then rotate the two sets of top-pressing screws 8 to drive the cross body 1 through threaded transmission, thereby driving the top-pressing screws 8 to move. When the abutment block 9 at one end of the top-pressing screw 8 contacts the locking key b5, it will push the locking key b5, causing it to slide in the keyway 7 inside the round hole a2. When the arc surface on one side of the two sets of locking keys b5 abuts against the connecting rod inside the round hole a2 and the round hole b3, the locking key b5 will be unable to move, and because of the locking key... The diameter of the arc surface on one side of b5 is the same as the diameter of the corresponding connecting rod, so it can make surface contact with the connecting rod, thereby stabilizing and limiting the two sets of connecting rods. The through holes 6 in the protrusions at both ends of the locking key b5 can be used to tie thin ropes. The thin ropes are connected to the corrector connecting rods to ensure that they will not fall out during installation. When the top screw 8 rotates, since it contacts the locking key b5 through the abutment block 9 at one end, and the abutment block 9 can rotate, the abutment block 9 will only press the keyway 7, and will not cause drilling damage to one side of the keyway 7, causing wear to the keyway 7. In this way, the connecting rods inside the cross body 1 can be easily disassembled and assembled through the above operation.

[0024] Example 2:

[0025] Please see Figure 1 , Figure 2 and Figure 5 Based on Embodiment 1, two sets of anti-accidental operation mechanisms for the pressing screw 8 are also disclosed, as follows: A handle 10 is rotatably connected to one end of the pressing screw 8, and a locking mechanism is provided inside the handle 10; the anti-accidental operation mechanism for the pressing screw 8 has the following specific structure: the locking mechanism includes an annular groove 11 on the outside of the pressing screw 8, and a limiting ring 12 is rotatably connected to the outside of the annular groove 11. The outside of the limiting ring 12 is fixed to the handle 10, and the limiting ring 12, the annular groove 11, and the pressing screw 8 constitute a rotating structure; multiple sets of slots 13 are provided at the end of the pressing screw 8 away from the abutment block 9, and a locking block 14 is fixedly connected to the inside of the handle 10, the width of the slot 13 being greater than the thickness of the locking block 14; a spring 15 abuts at one end of the pressing screw 8, and one end of the spring 15 abuts against the inside of the handle 10, and the handle 10, the spring 15, and the pressing screw 8 constitute an elastic telescopic mechanism.

[0026] The cross-shaped connecting bracket of this easy-to-install and easy-to-disassemble calibrator requires the use of a handle 10 when rotating the top-pressing screw 8. To prevent accidental contact with the handle 10 during normal operation, which could cause the locking key b5 to disengage from its clamping limit on the connecting rod, multiple sets of slots 13 are provided at the end of the top-pressing screw 8. When the top-pressing screw 8 needs to be rotated, pushing the handle 10 will compress the internal spring 15. Simultaneously, the locking block 14 inside the handle 10 will also move accordingly. When the locking block 14 engages with the slot 13 at the end of the top-pressing screw 8, it can... Rotating the handle 10 causes the top screw 8 to rotate, which can tighten or loosen the keyway 7. After the connecting bracket inside the cross body 1 is installed, the handle 10 can be released, and the spring 15 will push the handle 10 to reset, causing the locking block 14 inside the handle 10 to disengage from the locking slot 13. Therefore, if the handle 10 is accidentally rotated, the handle 10 will not drive the abutment block 9 to rotate, thereby preventing the locking key b5 from disengaging from the clamping limit of the connecting rod. In this way, the top screw 8 can be protected against accidental contact through the above operation.
