Description
Technical Field
[0001] The utility model relates to the technical field of fasteners, in particular to a fastener for mechanical maintenance. Background Art
[0002] Fasteners are also called standard parts in the market. They are a general term for a type of mechanical parts used to fasten two or more parts (or components) into a whole. They are characterized by a wide variety of specifications, different performances and uses, and a high degree of standardization, serialization, and generalization. Fasteners are the most widely used basic mechanical parts and are in great demand. When repairing a machine, it is generally necessary to fix the machine to be repaired first. Therefore, fasteners are also needed when repairing a machine.
[0003] However, existing fasteners also have shortcomings when in use. Existing fasteners are prone to loosening when in use. When performing mechanical maintenance, the machine may vibrate, thereby driving the fasteners to vibrate, thereby causing the fasteners to loosen. For this reason, the present application proposes a fastener for mechanical maintenance. Utility Model Content
[0004] In view of the deficiencies in the prior art, the utility model provides a fastener for mechanical maintenance.
[0005] The embodiment of the utility model provides a fastener for mechanical maintenance, comprising:
[0006] A limit block, to which a bolt is fixedly connected;
[0007] Anti-loosening component; the anti-loosening component includes a limiting cylinder fixed on the limiting block and sleeved on the outside of the bolt, the limiting cylinder is provided with a plurality of slots, a nut is threadedly connected to the bolt, the nut is fixedly connected to a connecting cylinder, a clamping ring is fixed on the connecting cylinder, the connecting cylinder is sleeved on the outside of the limiting cylinder and slidably connected thereto, a sliding card is passed through the connecting cylinder, the card is slidably connected in the slot, and the card is fixed to the connecting cylinder by a rubber sheet.
[0008] Furthermore, the limiting cylinder, the connecting cylinder and the bolt are coaxially arranged.
[0009] Furthermore, the clamping slot is arranged in a strip shape, and a plurality of the clamping slots are distributed in a circular array outside the limiting cylinder.
[0010] Furthermore, a through slot is formed through the connecting tube, and the card is slidably connected in the through slot.
[0011] Furthermore, both ends of the rubber sheet along the circumferential direction of the connecting cylinder are fixed on the connecting cylinder.
[0012] Furthermore, the card is made of stainless steel.
[0013] Compared with the prior art, the utility model has the following beneficial effects:
[0014] The card of the utility model is inserted into the card slot through the through slot to limit the connection cylinder so that it will not rotate, and further limit the nut so that it will not rotate with the bolt, and further the bolt and the nut will not loosen due to vibration, thereby ensuring the quality of fastening. BRIEF DESCRIPTION OF THE DRAWINGS
[0015] Figure 1 It is a schematic structural diagram of a fastener for mechanical maintenance described in an embodiment of the utility model.
[0016] Figure 2 This is a disassembled view of a connecting tube in a fastener for mechanical maintenance described in an embodiment of the utility model.
[0017] Figure 3 It is a schematic diagram of a bolt in a fastener for mechanical maintenance described in an embodiment of the utility model.
[0018] In the above drawings: 1 is a limit block, 2 is a bolt, 3 is a connecting tube, 4 is a clamping ring, 5 is a limit tube, 6 is a slot, 7 is a rubber sheet, 8 is a card, and 9 is a nut. DETAILED DESCRIPTION
[0019] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0020] like Figure 1-Figure 3 As shown, the embodiment of the utility model provides a fastener for mechanical maintenance, comprising:
[0021] A limit block 1, to which a bolt 2 is fixedly connected;
[0022] Anti-loosening component; the anti-loosening component includes a limiting cylinder 5 fixed on the limiting block 1 and sleeved on the outside of the bolt 2, and a plurality of slots 6 are provided on the limiting cylinder 5, and the slots 6 are arranged in a long strip shape, and the plurality of slots 6 are distributed in a circular array on the outside of the limiting cylinder 5; a nut 9 is threadedly connected to the bolt 2, and the nut 9 is fixedly connected to the connecting cylinder 3, wherein the limiting cylinder 5, the connecting cylinder 3 and the bolt 2 are coaxially arranged.
[0023] A clamping ring 4 is fixed on the connecting tube 3, and the connecting tube 3 is sleeved on the outside of the limiting tube 5 and slidably connected thereto. A sliding card 8 is penetrated through the connecting tube 3, and the card 8 is slidably connected in the card slot 6. A through groove is penetrated through the connecting tube 3, and the card 8 is slidably connected in the through groove. The card 8 is made of stainless steel to ensure the hardness of the card 8.
[0024] The card 8 is fixed to the connecting tube 3 by a rubber sheet 7, and both ends of the rubber sheet 7 along the circumferential direction of the connecting tube 3 are fixed to the connecting tube 3. Therefore, when the nut 9 is threadedly connected to the bolt 2, the staff can pinch the card 8 to disengage it from the through groove, and then place the card 8 at an angle to abut against the outer wall of the connecting tube 3, but it will not contact the connection where the rubber sheet 7 is fixed to the connecting tube 3. In this way, when the nut 9 is connected to the bolt 2, the card 8 will not interfere with the movement between the connecting tube 3 and the limiting tube 5; when the clamping ring 4 abuts against the contact surface, the mechanical workpiece is tightly positioned, and then the card 8 is pulled to pass through the through groove and inserted into the card slot 6, so that the connecting tube 3 is limited so that it will not rotate, and then the nut 9 is limited so that it will not rotate with the bolt 2, and then the bolt 2 and the nut 9 will not loosen due to vibration, thereby ensuring the quality of the fastening.
[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
