Description
Technical field
The present invention relates to pad technical field, specially a kind of screw retention pad.
Background technology
Pad is the mechanical seal between two objects, generally to prevent from being under pressure between two objects, corrode and
Pipeline expands with heat and contract with cold leakage naturally.Because machining surface can not possibly be perfect, scrambling can be filled up using pad, is padded
Piece is generally made up of flaky material, such as packing paper, rubber, silicon rubber, metal, cork, felt, neoprene, nitrile rubber, glass
Fiber, metal or plastic polymer (such as polytetrafluoroethylene (PTFE)), the pad of application-specific may contain asbestos, bolted bolt
Tighten it is fixed after, because mechanical shock acts on, easily there is loose or dislocation, influence the connection of connector, endanger equipment safety and
Service life, therefore need a kind of New anti-loose pad badly in actual production life, based on this, the present invention devises a kind of screw retention
Pad, to solve the above problems.
The content of the invention
It is an object of the invention to provide a kind of screw retention pad, to solve the actual life proposed in above-mentioned background technology
Produce the problem of needing a kind of New anti-loose pad badly in living.
To achieve the above object, the present invention provides following technical scheme：A kind of screw retention pad, including metal ring sheet
Body, the top of the metal ring body are provided with connection ratchet part, and the bottom of the metal ring body is provided with friction toothed region,
The inwall of the metal ring body is provided with vertical strip lines.
Preferably, the metal ring body is integral structure with being connected ratchet part and friction toothed region.
Preferably, the outer wall of the metal ring body is provided with frosting.
Preferably, the integral thickness of the metal ring body, connection ratchet part and the toothed region three that rubs is in 1.5-2.5
Between millimeter.
Preferably, the ratchet number of the connection ratchet part is between 8-30.
Preferably, the tooth form of the friction toothed region is straight tooth-shaped or bent tooth form.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention is by the way that the connection ratchet part of two groups of pads is folded
Close, bolt passes through two groups of pads, and locking nut is bolted with bolt, and the vertical strip lines of metal ring inner body wall can
Frictional force between increase and bolt, the friction toothed region of upper gasket contact with the nut medial surface of bolt, lower gasket
Friction toothed region contacted with the upper surface of locking nut, prevent circumferential slip using the toothed region that rubs, connection ratchet part is just
Two groups of pads is coincide, reduce dislocation, the device makes bolt connection more firm, easy to use.
Brief description of the drawings
In order to illustrate the technical solution of the embodiments of the present invention more clearly, used required for being described below to embodiment
Accompanying drawing is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the present invention, for ability
For the those of ordinary skill of domain, on the premise of not paying creative work, it can also be obtained according to these accompanying drawings other attached
Figure.
Fig. 1 is schematic structural view of the invention；

Embodiment, belong to the scope of protection of the invention.
Fig. 1-3 are referred to, the present invention provides a kind of technical scheme：A kind of screw retention pad, including metal ring body
1, the top of metal ring body 1 is provided with connection ratchet part 2, and the bottom of metal ring body 1 is provided with friction toothed region 3, metal
The inwall of ring body 1 is provided with vertical strip lines 4.
Wherein, metal ring body 1 is integral structure with being connected ratchet part 2 and friction toothed region 3, is easy to keep tying
The integrality of structure, the outer wall of metal ring body 1 are provided with frosting, conveniently pick up the pad for dropping to ground, metal ring sheet
The integral thickness of body 1, connection ratchet part 2 and the three of toothed region 3 that rubs connects the ratchet of ratchet part 2 between 1.5-2.5 millimeters
For number between 8-30, the tooth form of friction toothed region 3 is straight tooth-shaped or bent tooth form, makes frictional connection more firm.
One of the present embodiment has particular application as：As shown in figure 3, the connection ratchet part 2 of two groups of pads is overlapped, bolt is worn
Two groups of pads are crossed, and locking nut is bolted with bolt, the vertical strip lines 4 of the inwall of metal ring body 1 can increase
Frictional force between bolt, the friction toothed region 3 of upper gasket contact with the nut medial surface of bolt, the friction of lower gasket
Toothed region 3 contacts with the upper surface of locking nut, prevents circumferential slip using the toothed region 3 that rubs, connection ratchet part 2 just makes two
Group pad coincide, and reduces dislocation.
