Description

Technical Field

[0001] The utility model relates to a locking strip, in particular to a fixing rod structure of the locking strip, and belongs to the technical field of locking strips. Background Art

[0002] Locking strips are often used to install some equipment modules in the chassis. The wedge block on the locking strip is moved by turning the screw and abuts against the equipment module to fix the equipment module. Since it does not require traditional screws to fix, it is more convenient during installation and removal.

[0003] According to the patent document: CN201621101759.X, a locking strip is proposed, including a base, a push rod, a wedge block, a connecting block, a screw and a pin; the base includes a base body, a boss at one end of the base body, a plurality of wedge-shaped protrusions and a push rod positioning groove; the push rod includes a push rod body, a positioning clamp edge, a push buckle and a pin through hole; the number of the wedge blocks is the same as the number of the wedge protrusions, and each wedge block includes a pin mounting hole, a positioning clamp groove and a buckle groove. The utility model connects the wedge block and the push rod through a pin, and uses a screw to push the whole to tighten the device, thereby reducing the insertion effect during vertical installation; the push buckle on the push rod fine-tunes the surface flatness of the upper surface of each wedge block with the fixed plane, ensuring that the upper and lower surfaces of the locking strip are in close contact with the device and the box, thereby increasing the heat transfer area.

[0004] However, a locking strip in the above technology does not have a corresponding protective structure on the screw. If the screw is accidentally touched, the screw will easily rotate and drive the wedge block to move, so that the wedge block on the locking strip will squeeze the equipment module less, resulting in a worse fixing effect of the locking strip. Utility Model Content

[0028] An embodiment of the utility model provides a fixing rod structure of a locking strip.

[0029] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6The screw rod 20 is provided with a protection mechanism, which includes a sleeve 23, a block 22 and a first spring 24 are fixedly connected inside the sleeve 23, the first spring 24 is sleeved on the outside of the screw rod 20, a slot 21 is provided on the screw rod 20, a slider 25 is fixedly connected to the right side of the sleeve 23, the slider 25 abuts against the block 26, a second spring 28 is fixedly connected to the right side of the block 26, the slider 25 is slidably connected to the inside of the slide groove 27, the slide groove 27 is provided on the fixing ring 29, the fixing ring 29 is fixedly connected to the fixing rod body 1, a self-locking mechanism is provided on the sleeve 23, the self-locking mechanism includes a mounting shell 33, a rotating rod 32 is rotatably connected inside the mounting shell 33, a gear 31 and a ratchet 34 are fixedly connected to the rotating rod 32, the ratchet 34 is engaged with the pull rod 36, a third spring 35 is sleeved on the pull rod 36, and a first gear ring 30 is sleeved on the sleeve 23.

[0030] When the utility model is in use, the sleeve 23 is separated from the screw 20, and only when the sleeve 23 is pressed, the sleeve 23 can be rotated to drive the screw 20 to rotate, so that the protection of the screw 20 is better, and the situation that the screw 20 rotates due to accidental contact is reduced. When the screw 20 needs to be rotated, since the sleeve 23 is supported by the first spring 24, the sleeve 23 must be pressed first to overcome the elastic force of the first spring 24 until the fixed block 22 inside the sleeve 23 is inserted into the slot 21, and then the screw 20 can be rotated. The screw rod 20 is driven to rotate by rotating the sleeve 23. During the rotation of the sleeve 23, the slider 25 fixed on the right side of the sleeve 23 rotates in the slide groove 27. The slider 25 abuts against the stop block 26 and a second spring 28 is fixed on the stop block 26 to provide space for the slider 25 to move inside the slide groove 27. The cross-section of the slider 25 is T-shaped to ensure that the sleeve 23 will not be separated from the fixing ring 29. When the block 22 is not inserted into the slot 21, rotating the sleeve 23 will not drive the screw rod 20 to rotate.

[0031] The ratchet wheel 34 is designed to ensure that the sleeve 23 can only rotate in a single direction, that is, the direction of tightening the screw 20, during the rotation of the sleeve 23, to ensure that the sleeve 23 will not rotate in the opposite direction. A first gear ring 30 is fixed to the sleeve 23. During the pressing of the sleeve 23, the first gear ring 30 will also move to the bottom end of the mounting shell 33 and mesh with the gear 31. Since the gear 31 and the ratchet wheel 34 are fixed on the same rotating rod 32, the self-locking of the ratchet wheel 34 can ensure that the sleeve 23 will not rotate in the opposite direction. The part where the pull rod 36 and the ratchet wheel 34 engage with each other is trapezoidal in design, and a third spring 35 is sleeved on the pull rod 36 to maintain the contact between the third spring 35 and the ratchet wheel 34. The side of the pull rod 36 away from the ratchet wheel 34 passes through the mounting shell 33 and is arranged on the outside of the mounting shell 33, so that the pull rod 36 and the ratchet wheel 34 can be released by pulling the pull rod 36, so that the sleeve 23 can rotate in the opposite direction.

[0032] Please refer again Figure 2 , Figure 3 and Figure 5 A second gear ring 45 is fixedly connected to the sleeve housing 23 . The second gear ring 45 is located on the right side of the first gear ring 30 . The second gear ring 45 is meshed with the gear 31 .

[0033] When the utility model is in use: a second gear ring 45 is further provided on the right side of the first gear ring 30, and the second gear ring 45 is kept in meshing with the gear 31, so that when the sleeve 23 is pressed, the first gear ring 30 can be smoothly meshed with the gear 31 to avoid the first gear ring 30 from abutting against the gear 31, and when the sleeve 23 is not pressed, the second gear ring 45 will be kept in meshing with the gear 31, so that when the sleeve 23 is subsequently pressed, the first gear ring 30 can also be smoothly meshed with the gear 31, wherein a washer 42 is also fixed on the second gear ring 45, and the washer 42 is used to avoid the second gear ring 45 from directly abutting against the fixing ring 29.

[0034] Please refer again Figure 2 , Figure 3 and Figure 4 A collar 37 is fixedly connected to the inner wall of the mounting shell 33, and a rubber ring 38 is sleeved on the inner wall of the collar 37. The rubber ring 38 contacts the rotating rod 32. Two groups of mounting blocks 40 are fixedly connected to the right side of the mounting shell 33. The mounting blocks 40 are slidably connected to the inside of the mounting groove 41. The mounting groove 41 is provided on the fixing rod body 1. The mounting shell 33 is threadedly connected with a screw, and a notch 39 is provided at the bottom end of the mounting shell 33.

[0035] When the utility model is in use: when the gear 31 drives the rotating rod 32 to rotate, one side of the rotating rod 32 will contact the rubber ring 38, so as to increase the friction force of the rotating rod 32 during the rotation process, ensuring that the rotating rod 32 will not be too flexible during the rotation process, so as to facilitate the meshing between the gear 31 and the first gear ring 30.

[0036] The mounting shell 33 is pre-fixed on the fixing rod body 1 by sliding in the mounting groove 41 through two sets of mounting blocks 40, and the mounting blocks 40 and the mounting groove 41 are both trapezoidal in design. After the mounting shell 33 is pre-fixed, the mounting shell 33 is fixed to the fixing rod body 1 by screws to facilitate the installation and removal of the mounting shell 33. A notch 39 is also provided on the bottom end of the mounting shell 33, and the notch 39 is arc-shaped to ensure that the first gear ring 30 and the second gear ring 45 will not abut against the bottom end of the mounting shell 33.
