Description
Technical field
The technical field of pad is the utility model is related to, more specifically, it relates to a kind of cushioning piece.
Background technology
During screw, screw rod connection, pad can be arranged on screw and screw rod to improve bonding strength, it is traditional
Gasket construction is that the connecting hole is used for screw and screw rod runs through with a connecting hole, and pad is plain cushion structure, and this kind is tied
The poor effect to screw or nut bumper and absorbing shock that structure plays.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of rational in infrastructure simple, practicality
Property is strong, and damping effect is strong, the strong cushioning piece of voltage endurance capability.
To achieve the above object, the utility model provides following technical scheme：
A kind of cushioning piece, including shim body, shim body include the external toroidal ring and inner collar being connected with each other, inner collar
On offer connecting hole, the lower surface direction of inner collar to external toroidal ring is raised and is formed between the inwall of external toroidal ring and has reinforcement ditch
Being formed on the junction of groove, inner collar and external toroidal ring has annular groove, and fastener, external toroidal ring insertion annular are provided with annular groove
Connected in groove with fastener, the opening of the connecting hole is provided with first annular stiffening ring, the lower surface interior edge of external toroidal ring
Place is provided with the second annular stiffening ring.
By using above-mentioned technical proposal, pad is arranged to the structure of inside and outside ring, external toroidal ring, which is used to support, to be connected,
Inner collar is used for screw or screw rod and run through, set on the junction of inner collar and external toroidal ring fastener be used for compensator or trimmer pressure and
Damping, due to the protrusion direction of inner collar and external toroidal ring on the contrary, and then producing the interior force direction for offsetting external force both in stress
Also on the contrary, and then substantially increasing the anti-pressure ability of pad.The setting of first annular stiffening ring substantially increases the knot of inner collar
Structure intensity, the setting of the second annular stiffening ring substantially increase the structural strength and structural stability of external toroidal ring, and the second ring
Shape stiffening ring and work top contact, greatly reduce abrasion.
The utility model is further arranged to：The fastener offers the holding tank stretched into for inner collar, holding tank
Bottom land offer V-shape opening with inner collar end adapter, be evenly equipped with corresponding to the V-shape opening on the inwall of both sides some
Contact, the contact that the inner collar is stretched on V-shape opening and its both sides inwall contradict.
By using above-mentioned technical proposal, fastener is just installed in annular groove before shim body shaping, by
Fastener and external toroidal ring are fastened again after ring insertion, and then ensure that the mounting stability of fastener and reduce external toroidal ring
The forming gap between inner collar.Contact on fastener inwall, which is used to buffer, depressurizes, in pad stress, touching on fastener
Point can buffer external force, offsets external force and then ensure the structural strength of pad.
Brief description of the drawings
Fig. 1 is structure sectional view of the present utility model
Fig. 2 is the structural representation of the utility model fastener V-shape opening.
Embodiment
Embodiment of the present utility model is described further referring to figs. 1 to Fig. 2.
A kind of cushioning piece, including shim body, shim body include the external toroidal ring 1 and inner collar 2 being connected with each other, inner ring
Connecting hole 20 is offered on circle 2, the lower surface direction of inner collar 2 to external toroidal ring 1 is raised and is formed between the inwall of external toroidal ring 1
There is a reinforcement groove, being formed on the junction of inner collar 2 and external toroidal ring 1 has annular groove, is provided with fastener 3 in annular groove, outside
Ring 1 is inserted in annular groove and connected with fastener 3, and the opening of the connecting hole 20 is provided with first annular stiffening ring 21,
The second annular stiffening ring 11 is provided with the lower surface interior edge of external toroidal ring 1.
Pad is arranged to the structure of inside and outside ring 1, external toroidal ring 1, which is used to support, to be connected, and inner collar 2 is used for screw or spiral shell
Bar runs through, and sets fastener 3 to be used for compensator or trimmer pressure and damping on the junction of inner collar 2 and external toroidal ring 1, due to inner collar
2 and external toroidal ring 1 protrusion direction on the contrary, and then producing the interior force direction for offsetting external force both in stress also on the contrary, and then big
The big anti-pressure ability for improving pad.The setting of first annular stiffening ring 21 substantially increases the structural strength of inner collar 2, the
The setting of second ring stiffening ring 11 substantially increases the structural strength and structural stability of external toroidal ring 1, and the second annular is strengthened
Circle 11 and work top contact, greatly reduce abrasion.
The fastener 3 offers the holding tank stretched into for inner collar 2, and the bottom land of holding tank offers and inner collar 2
The V-shape opening 30 of end adapter, if being evenly equipped with dry contact 3a, the inner ring corresponding to the V-shape opening 30 on the inwall of both sides
The contact 3a that circle 2 is stretched on V-shape opening 30 and its both sides inwall is contradicted.
Fastener 3 is just installed in annular groove before shim body shaping, again by fastener after inner collar 2 is inserted
3 and external toroidal ring 1 fasten, and then ensure that the mounting stability of fastener 3 and reduce between external toroidal ring 1 and inner collar 2 into
Type gap.Contact 3a on the inwall of fastener 3, which is used to buffer, to be depressurized, and in pad stress, the contact 3a on fastener 3 can be buffered
External force, offset external force and then ensure the structural strength of pad.
Preferred embodiment of the present utility model is the foregoing is only, not limiting the utility model, the skill of this area
Art personnel carry out common variations and alternatives in the range of technical solutions of the utility model should all be included in guarantor of the present utility model
In the range of shield.
