Description

Technical Field

[0001] The utility model belongs to the technical field of hardware, and in particular relates to a rotating fastener. Background Art

[0002] At present, rotatable and lockable plates are used in required fields. At present, such plates are mostly installed by using a rotating shaft as a rotating support point, and locking devices are arranged on them for locking. At present, the locking devices mostly adopt locking bolts. The plate is locked by tightening the locking bolts, and the plate can be contact-locked by loosening the locking bolts. However, the tightening or loosening of the locking bolts usually requires the use of wrench-like devices, which makes the operation complicated. In addition, the locking bolts usually protrude from the plate, which affects the appearance and normal use. For plates with high requirements for balance during rotation, the locking bolts arranged thereon will also affect their balance. Utility Model Content

[0003] In order to solve the above technical problems, the purpose of the utility model is to provide a rotating fastener that can rotatably install a balancing board relative to a carrier and conveniently lock the balancing board.

[0004] In order to achieve the above-mentioned purpose, the technical scheme of the utility model is as follows: a rotating fastener comprises a carrier plate, a balance plate and a knob plate which are stacked in sequence, the middle part of the carrier plate is rotatably connected to the balance plate, the knob plate is arranged on a side of the balance plate away from the carrier plate, and the knob plate can move away from or towards each other relative to the balance plate, a limiting groove is concavely provided on a side of the carrier plate close to the balance plate, a limiting hole is arranged on the balance plate, and a limiting groove is convexly provided on a side of the knob plate close to the balance plate The knob plate and the balance plate can be rotated relative to the carrier plate until the limiting groove, the limiting hole and the limiting tooth are aligned, and when the limiting groove, the limiting hole and the limiting tooth are aligned, the knob plate is pressed to move the knob plate close to the balance plate, and the limiting tooth passes through the limiting hole and is inserted into the limiting groove to limit the balance plate relative to the carrier plate, or the knob plate is pushed to move away from the balance plate so that the limiting tooth retreats out of the limiting groove to release the limiting of the balance plate.

[0005] The beneficial effect of the above technical solution is that: in this way, the balance plate uses the carrier plate as a rotating carrier. When the balance plate needs to rotate relative to the carrier plate, it is only necessary to move the knob plate away from the balance plate, so that the limiting teeth retreat into the limiting hole or retreat out of the limiting hole. When the limiting teeth retreat into the limiting hole, the balance plate can drive the knob plate to rotate synchronously when it rotates. When the limiting teeth retreat out of the limiting hole, the balance plate will not drive the knob plate to rotate when it rotates.

[0006] In the above technical solution, the carrier plate is also provided with a plurality of mounting holes penetrating therethrough, and the plurality of mounting holes are distributed circumferentially and spaced apart around the rotational connection between the carrier plate and the balance plate.

[0009] The beneficial effect of the above technical solution is that the balance plate is rotatably connected to the connecting column, and the connecting column serves as a mounting carrier of the knob plate, thereby making the mounting of the carrier plate, the balance plate and the knob plate simpler.

[0010] In the above technical solution, a receiving groove is recessed on one side of the balance plate close to the knob plate, and the knob plate is arranged in the receiving groove, the limiting hole is arranged on the bottom wall of the receiving groove, and the groove depth of the receiving groove is not less than the thickness of the knob plate.

[0011] The beneficial effect of the above technical solution is that when the balance board is locked by the knob plate, the entire knob plate is located in the receiving groove, thereby making the balance board more aesthetically pleasing.

[0012] In the above technical solution, a slot is coaxially provided at one end of the connecting column away from the carrier plate, and a tooth is coaxially provided at one end of the knob plate close to the balance plate, and the tooth is inserted into the slot, and the tooth can move axially relative to the slot to drive the knob plate to move closer to or away from the balance plate.

[0013] The beneficial effect of the above technical solution is that such a suitable knob plate can be installed more conveniently at the end of the connecting column, and the knob plate can move axially relative to the connecting column.

[0014] In the above technical solution, the slot is a trumpet-shaped slot, the smaller end of which is away from the carrier plate, and the inserting teeth are frustum-shaped, the thick end of which is away from the knob plate.

[0016] In the above technical solution, one end of the connecting column close to the knob plate is flush with the bottom wall of the accommodating groove.

[0017] The beneficial effect of the above technical solution is that when the knob plate is locked to the balance plate, it can fit with the balance plate, so that the depth of the accommodating groove can be only the thickness of the balance plate.

[0018] In the above technical solution, the accommodating groove is a circular groove, and its diameter is consistent with the diameter of the knob plate.

[0019] The beneficial effect of the above technical solution is that the knob plate can be limited by the accommodating groove, so that the knob plate maintains a coaxial distribution with the connecting column.

[0020] In the above technical solution, two hand-gripping grooves are further provided at the edge of the accommodating groove, which are connected to the interior and distributed opposite to each other, and two notches are recessed at the edge of the knob plate close to one side of the balance plate, and when the limiting tooth is aligned with the limiting groove, the two notches are respectively aligned with the two hand-gripping grooves.

The knob plate 3 is moved close to the balance plate 2, and the limiting tooth 31 passes through the limiting hole 21 and is inserted into the limiting groove 11 to limit the balance plate 2 relative to the carrier plate 1, or the knob plate 3 is moved away from the balance plate 2 so that the limiting tooth 31 retreats out of the limiting groove 11 to release the limiting of the balance plate 2. In this way, the balance plate uses the carrier plate as a rotating carrier. When the balance plate needs to rotate relative to the carrier plate, it only needs to move the knob plate away from the balance plate, so that the limiting tooth retreats into the limiting hole or retreats out of the limiting hole. When the limiting tooth retreats into the limiting hole, the balance plate can drive the knob plate to rotate synchronously when it rotates. When the limiting tooth retreats out of the limiting hole, the balance plate will not drive the knob plate to rotate when it rotates.

[0036] like Figure 7 As shown, the carrier plate 1 in the above technical solution is also provided with a plurality of mounting holes 12 penetrating therethrough, and the plurality of mounting holes 12 are circumferentially spaced around the rotational connection between the carrier plate 1 and the balance plate 2, so that each mounting hole on the carrier plate can be passed through a nail or a bolt for fixed installation.

[0038] like Figure 4 and Figure 5 As shown, in the above technical solution, a receiving groove 22 is recessed on one side of the balance board 2 close to the knob plate 3, and the knob plate 3 is arranged in the receiving groove 22, and the limiting hole 21 is arranged on the bottom wall of the receiving groove 22, and the groove depth of the receiving groove 22 is not less than the thickness of the knob plate 3, so that when the balance board is locked by the knob plate, the entire knob plate is located in the receiving groove, thereby making the balance board more aesthetically pleasing.

[0041] like Figure 1-Figure 3 As shown, in the above technical solution, one end of the connecting column 13 close to the knob plate 3 is flush with the bottom wall of the receiving groove 22, so that when the knob plate is locked to the balance plate, it can fit with the balance plate, so that the depth of the receiving groove can be only the thickness of the balance plate.

[0045] Preferably, the arc center angles corresponding to the limiting groove, limiting hole and limiting tooth are all 90°, and the arc center angle corresponding to the notch is also 90°, and the two notches and the two limiting teeth are circumferentially staggered at the edge of the knob plate.

[0046] like Figure 1-Figure 3 As shown, in this embodiment, for the knob plate, when it locks the balance plate, the limiting teeth are straightened by the limiting holes, and the knob plate and the connecting column are in a coaxial distribution state. When the knob plate is unlocked from the balance plate, the inserting teeth and the slots cooperate, and the knob plate and the connecting column are still in a coaxial distribution state.
