Description
Technical field
The present invention relates to fascia rifle massage head technical field, more specifically, it relates to a kind of fascia rifle massage head and its
Formula for raw stock and processing technology.
Background technique
At the beginning of 2018, a kind of massage instrument fascia rifle loosened for muscular fascia occurs and popular on the market, it leads
Massage is carried out to body part position in such a way that vertical vibration strikes to loosen.It is general with the massage head of direct physical contact
Wooden, nylon, rubber, silica gel, ABS material production can be used.Above-mentioned material manufacture craft is simple, and yield is high.
But pass through 1 year market sale and consumer feedback, main problem existing for existing fascia rifle massage head is
Experience sense is poor.The experience of some material consumers gets off to think that impact experience is really up to the mark, such as nylon and ABS, unsuitable old man,
The portion of muscle weakness with child and adult.Some material consumers think that impact experience is too soft, such as such as silica gel, rubber,
Simultaneously to the stimulation of muscle and deep less than relaxation effect is undesirable.And it is not wear-resisting to also proposed silicone gum rubber these materials, holds
It is easy to damage.
Existing patent CN109758348A discloses a kind of fascia rifle and its mounting process comprising driving device, with drive
The massage head of dynamic device transmission connection；Driving device includes outer housing, is mounted on the intracorporal driving motor of shell, passes through bearing block
It is mounted on the crankshaft of in outer housing and one end and driving motor transmission connection, one end passes through bearing holder (housing, cover) mounted in eccentric shaft in the middle part of crankshaft
Connecting rod that upper and one end connect with crankshaft shaft end and the hinged articulated joint of the connecting rod other end, setting in outer housing and with driving
The vertical telescopic shaft of electrical axis line, setting are in outer housing and its inner set is arranged for telescopic shaft activity and setting exists
Flexible shaft end head and the electric rotating head for being exposed to outer housing；The present invention has rational design, compact-sized and easy to use.
Patents documents at present about fascia rifle massage head are considerably less, and the main direction of studying of each producer is designing
Moulding, design driven aspect.And above-mentioned market survey consumer feedback the technical issues of going out, rare have research, is badly in need of finding
A kind of more good material and technique make massage head.
Summary of the invention
In view of the deficiencies of the prior art, the present invention intends to provide a kind of fascia rifle massage head, specific hardness
The moderate comfortable effect of massage.
To achieve the above object, the present invention provides the following technical scheme that a kind of fascia rifle massage head, including massage head sheet
Body, the massage head include Massage Department and the interconnecting piece of integrally connected, and the material of the massage head is casting type polyurethane
Elastomeric material.
By using above-mentioned technical proposal, the mechanical strength with higher of massage head made of polyurethane and oxidation are steady
It is qualitative, while flexibility with higher and resilience, it springs back rapidly, meets while contacting human body and guaranteeing that soft comfortable is spent
And the massage comfort level requirement of people can be improved.The high-frequency operation demand of fascia rifle is also adapted to simultaneously.
Further, Massage Department's global shape be " V " type, U-typed, T-shape, " ox horn " type, spade-type, dome-type,
Cone, tapered trapezoid, triangular pyramidal, polyhedron globe or multi-panel are special-shaped.
By using above-mentioned technical proposal, for muscle at neck-massaging function, user can be according to itself not for Massage Department
Same situation selects Massage Department.The massage head of cattle horn shape meets ergonomic designs, and outwardly projecting cattle horn shape massages neck
Muscle at two loosens muscle at neck two quickly, and the massage head of cattle horn shape was being massaged when massaging at neck
The cervical vertebra at neck will not be hit in journey, user is avoided to accidentally injure oneself, avoid personal injury occur when massage.U-shaped or V-type
Save space and raw material.Spade-type, tapered trapezoid are custom-shaped, can carry out linear massage.
Further, the interconnecting piece bosom is equipped with the mounting hole for rabbeting fascia rifle connector, the installation
Hole one end runs through, and the other end runs through end of the interconnecting piece far from Massage Department one end, and the interconnecting piece global shape is circle
Cylindricality, multiple ladders are round table-like, rectangle, top oblateness lower cone shape, oblate column or special-shaped column.
By using above-mentioned technical proposal, interconnecting piece is set as the main installation position with fascia rifle in its bottom centre
There is mounting hole.Shape is designed to different shape according to the different model of fascia rifle, adapts to the work requirements of fascia rifle.
Further, the interconnecting piece is equipped with locating piece or the second connector.
By using above-mentioned technical proposal, locating piece or the second connector further install fascia rifle whenever necessary
The Massage Department of other auxiliary accessories or external auxiliary provides a kind of more flexible connection type.
A kind of formula for raw stock of fascia rifle massage head, the casting type polyurethane elastomer material casting type polyurethane bullet
Elastomer material formula composition is as follows, by weight:
By using above-mentioned technical proposal, be made into a kind of massage head, the polyurethane that this material is formed have compared with
High mechanical strength and oxidation stability, while flexibility with higher and resilience guarantee soft comfortable in contact human body
It is sprung back rapidly while spending, meets the comfortable Experience Degree of people.The high-frequency operation demand of fascia rifle is also adapted to simultaneously.Polyurethane
Resin has the characteristics such as high intensity, tear-proof, wear-resisting.Foaming agent selects azo-compound, and sulfonyl hydrazines compound is ok.It is different
Cyanate is used to help the formation of polyurethane.
Further, the polyalcohol is polyester polyol or polyether polyol.
By using above-mentioned technical proposal, the polyester polyol ester group more because intramolecular contains, amino isopolarity group,
Cohesive strength and adhesive force are strong, intensity with higher, wearability.Obtained polyurethane elastomer crystallinity is strong, and initial bonding strength is big,
The mechanical strength for obtaining product is also higher.The adhesive for polyurethane that polyether polyol is prepared has good water resistance, shock resistance
Property and low temperature properties.
Further, it is N that the catalyst, which is catalyst, N- dimethyl cyclohexyl amine, bis- (2- dimethylaminoethyl) ethers, N,
N, N', N'- tetramethyl Alkylenediamine, triethylamine, N, N- dimethyl benzylamine, triethanolamine or DMEA.
By using above-mentioned technical proposal, in polyurethane elastomer preparation, above-mentioned catalyst promote isocyanate group with
Hydroxyl reflection, wherein reacting with acceleration to water and isocyanates.
Further, the casting type polyurethane elastomer material further includes 1-2 parts of EPS particles.
By using above-mentioned technical proposal, EPS grain density is low, and cost is also low, and the massage head of formation has multiple
Tiny hole, the space of reserved deformation further help to improve deformation space in the case where the hardness that polyurethane meets, mention
High-flexibility.
A kind of processing technology of fascia rifle massage head:
S1. according to customer demand, the shape of massage head is designed；
S2. the mold needed according to the product structure of designed massage head, production casting；
S3. raw material is configured: by 15-20 parts of isocyanates；60-70 parts of polyalcohol；5-10 parts of foaming agent；1-5 parts of catalyst by than
