Abstract
The utility model is a kind of improved arch rubber fender, top（1）With the leg of the left and right sides（2）Between joint portion medial surface be made up of three sections of arc surfaces of rounding off successively, wherein middle part arc surface（5）The center of circle up, middle part arc surface（5）The side arc surface of both sides（6）The center of circle is lower section.Compared with existing arch rubber fender, the utility model fender, which has, obtains more aximal deformation value（Fender is compressible to be deformed into 55%）, fender counter-force is lower, and energy absorption is higher, plays more preferable cushioning buffer effect, and fender mechanical structure is more reasonable.
Description
Technical field
A kind of rubber fender is the utility model is related to, specifically a kind of arch rubber fender.
Background technology
Arch rubber fender is also known as V-type rubber fender, and it has, and counter-force is moderate, and energy absorption is high and firmly installs, conveniently
The advantages that.Such as Fig. 1, the arch rubber fender as prior art is located at the leg of the left and right sides bottom of top 1 by top 1 and respectively
Portion 2 forms, and wherein the lower end of leg 2 carries foot, and the foot is used to connect harbour metope.Described top 1, leg 2 and pin
Portion is structure as a whole.Space between top 1 and the leg 2 of the left and right sides is approximate inverted " v ".The root of the inverted " v ", i.e.,
Joint portion medial surface between top 1 and two legs 2 is a center of circle in the arc area of lower section, and the region is also known as fender core
Sub- V-type cusp region, it be fender use when stress area of stress concentration, due to fender in deformation process stress concentration in this
Region, fender easily cause to tear in deformation process in the region.
On the other hand, existing arch rubber fender leg is uniform elongated shape, lacks deformation pilot point, in fender quilt
During compression, the easy stress in fender leg is excessive to cause fatigue damage.
Because existing arch rubber fender has above design defect, cause fender deflection small, design compression
45% is can only achieve, fender counter-force is higher, and energy absorption capacity is poor.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of improved arch rubber fender, has more preferable
Stress dispersive property and stress direction guide performance, to improve the tearing strength of arch rubber fender and endurance degree.
In order to solve the above-mentioned technical problem, the utility model employs following technical scheme：
A kind of improved arch rubber fender, including top and the leg for being located at bottom at left and right sides of top respectively, it is special
Sign is：Joint portion medial surface is made up of three sections of arc surfaces of rounding off successively between top and the leg of the left and right sides, its
Up, the side arc surface center of circle of middle part arc surface both sides is lower section in the middle part arc surface center of circle.
Described leg bottom has one section of opening portion expanded laterally, has one section of change on the inside of the upper end in the opening portion
Shape stress pilot arc.
The ratio that the height of distortional stress pilot arc accounts for fender total height is 30%-36%.
Top and leg surface are light color or colored.
Good effect of the present utility model is：
Firstth, the utility model is directed to the fault of construction of existing arch rubber fender, and V-type cusp position is changed into approximation and fallen
" W " type, the region force way is changed, improve the region fatigue releasability.
Secondth, the utility model is adding deformation point close to fender leg bottom position, when fender is extruded, guiding
Stress concentration excessively concentrates on V-type cusp in the deformation point position so as to solve stress in fender deformation process well
The problem of position, it is rationally and durable to further ensure fender deformation.
3rd, compared with existing arch rubber fender, the utility model fender, which has, obtains more aximal deformation value（Fender can
Compression is to 55%）, fender counter-force is lower, and energy absorption is higher, plays more preferable cushioning buffer effect, fender mechanical structure is more
Adduction is managed.
4th, fender body surface is light color or colored, and product colour is various, is not only imitated with more attractive vision
Fruit, and there is more preferable safety warning effect because of more eye-catching, so as to improve the security that product uses.
Brief description of the drawings
Fig. 1 is the planform schematic diagram of the arch rubber fender as prior art.
Fig. 2 is the planform and mounting means schematic diagram of the utility model embodiment.
Embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples.
As shown in Fig. 2 embodiment of the present utility model includes top 1 and is located at the leg of the left and right sides bottom of top 1 respectively
Portion 2, the wherein lower end of leg 2 carry foot, and the foot is used to connect harbour metope.Described top 1, leg 2 and foot be
Integrative-structure.
Joint portion medial surface is made up of three sections of arc surfaces of rounding off successively between top 1 and the leg 2 of the left and right sides,
One section of middle part center of circle of arc surface 5 placed in the middle is above, i.e., the section is protruded downwards, the side circular arc of the both sides of middle part arc surface 5
The center of circle of face 6 is located at lower section, i.e., this two sections protrude upward.
The described bottom of leg 2 has one section of opening portion 3 expanded laterally, has one on the inside of the upper end in the opening portion 3
Section distortional stress pilot arc 4.The ratio that the height h of distortional stress pilot arc 4 accounts for fender overall height H is 30%-36%.
In order to increase the aesthetic feeling of fender and security performance, top 1 and the surface of leg 2 are designed as light color or colored.
