Description
Technical field
The utility model relates to piano part field, specifically a kind of ejector rod shaft bracket.
Background technique
The assembling process of ejector rod shaft bracket and interlocking bar assembly are as follows: first in the hole of ejector rod shaft bracket bottom and the assembly of interlocking bar groove
Rooved face dips in glue, and then ejector rod shaft bracket is connected in interlocking bar groove, completes assembly after glue is dry.In assembling process
In, due to the extruding between ejector rod shaft bracket and interlocking bar, glue is easy outer spill and leakage and hangs, and causes the product appearance of assembly indecency, needs
Increase subsequent excessive glue treatment process, increases cost, influences efficiency；Simultaneously glue quantity deficiency be also easy to happen ejector rod shaft bracket from
Glue loosens phenomenon, even if loosening phenomenon from glue there is no ejector rod shaft bracket when assembly, but the subsequent of piano is played repeatedly
In the process, ejector rod shaft bracket is also easy to appear and loosens phenomenon from glue.Since ejector rod shaft bracket bottom sump rooved face is smooth, interlocking bar groove
Surface be also it is smooth, in assembly, the mobility of glue is preferable, is more easier to occur from glue to loosen phenomenon.
Utility model content
For the technical problems in the prior art, the purpose of this utility model is: providing a kind of ejector rod shaft bracket, the top
Bar pedestal is equipped with hiding glue groove, and hiding glue groove to dip in glue surface with certain roughness, stays glue effect good, increase ejector rod shaft bracket and
Glue-spread between interlocking bar, solve ejector rod shaft bracket in assembling process and it is subsequent occur to loosen from glue during play ask
Topic.
In order to achieve the above object, the utility model adopts the following technical solution:
A kind of ejector rod shaft bracket is assembled by glue and interlocking bar bonding, the pit slot and interlocking bar in ejector rod shaft bracket bottom
Glue adhesive layer is set between groove, several hiding glue grooves, the shape of glue adhesive layer are equipped at the pit slot of ejector rod shaft bracket bottom
The shape that gap is formed by between shape and pit slot and groove is identical.After this structure, hiding glue groove has the function of to hide glue, energy
Enough increase the glue-spread between ejector rod shaft bracket and interlocking bar, more glue can be accommodated, thus the case where avoiding excessive glue leakage from hanging
Occur, in addition, hiding glue groove increases ejector rod shaft bracket surface roughness, stays glue effect with certain.Glue after molding has
Part is extend into ejector rod shaft bracket, is reduced and is loosened phenomenon from glue with what is occurred during subsequent use in assembly.
Preferably, hiding glue groove is located at the top surface and/or side of pit slot.After this structure, glue after molding is perpendicular
To and/or extend transversely into ejector rod shaft bracket, increase the stability of bonding.
Preferably, hiding glue groove is symmetricly set on ejector rod shaft bracket bottom.After this structure, hiding glue groove is symmetrical arranged, glue
Water adhesive layer is also symmetrically that the bonding force of the bonding portion between glue adhesive layer and ejector rod shaft bracket is also symmetrical balance,
It avoids bonding force uneven and leads to the assembly unstability between ejector rod shaft bracket and interlocking bar.
Preferably, hiding glue groove is vee gutter.After this structure, due to the small volume of ejector rod shaft bracket, using three
Angle-shaped groove can be such that the contact area of glue adhesive layer and ejector rod shaft bracket maximizes, be conducive to increase ejector rod shaft bracket and interlocking bar it
Between glue-spread, it is more firm to make assembly, and then effectively prevent loosening the generation of phenomenon from glue.
Preferably, the depth for hiding glue groove is greater than or equal to 0.5cm.After this structure, guarantee the intensity of ejector rod shaft bracket
While meet glue adhesive layer glue-spread requirement.
Generally speaking, the utility model has the advantages that
The setting hiding glue groove on ejector rod shaft bracket and the fitting surface of interlocking bar assembly: 1. are conducive to increase ejector rod shaft bracket and linkage
Glue-spread between bar avoids the assembly of ejector rod shaft bracket from the phenomenon that loosening from glue occur；2. hiding glue groove can accommodate more glue
Water, thus the case where avoiding excessive glue leakage from hanging；3. hiding glue groove increases the pit slot surface roughness of ejector rod shaft bracket bottom, have
Have and certain glue is stayed to act on；4. glue after molding partially protrudes into ejector rod shaft bracket, increase glue adhesive layer and mandril axis
The contact area of frame increases bonding force, reduces and loosens phenomenon from glue with what is occurred during subsequent use in assembly.

Specific embodiment
Below with reference to examples and drawings, the utility model is described in more detail, but the reality of the utility model
It is without being limited thereto to apply mode.
A kind of ejector rod shaft bracket is applied to vertical qin hammered string instrument, is assembled by glue and interlocking bar bonding.
In the present embodiment, glue adhesive layer is set between the pit slot of ejector rod shaft bracket bottom and the groove of interlocking bar, is being pushed up
The top surface of the pit slot of bar pedestal bottom is symmetrically arranged with two depth by symmetry axis of the center line of ejector rod shaft bracket as the triangle of 0.5cm
It is identical to be formed by the shape in gap between the shape and pit slot and groove of glue adhesive layer for the hiding glue groove of shape.Glue adhesive layer
Bottom be cuboid, the raised line of two triangles is arranged at top.Raised line is extend into ejector rod shaft bracket, increase glue adhesive layer with
The contact area of ejector rod shaft bracket increases bonding force, reduces and loosens now with what is occurred during subsequent use from glue in assembly
As.Setting hiding glue groove is conducive to increase between ejector rod shaft bracket and interlocking bar on the fitting surface that ejector rod shaft bracket and interlocking bar assemble
Glue-spread avoids the assembly of ejector rod shaft bracket from the phenomenon that loosening from glue occur.
It is assembled after directly dipping in glue in the pit slot of the bottom of ejector rod shaft bracket with interlocking bar, it may appear that phenomenon is hung in glue leakage, is led
It causes glue adhesion to other positions, the process of daub need to be increased, increase cost.And glue can be effectively prevented from after increasing hiding glue groove
The case where outer spill and leakage of water is hung.If increasing hiding glue groove in interlocking bar groove, increase the machining work of hiding glue groove in groove
Skill is extremely complex, and difficulty is high, is not easy to realize.And increase hiding glue groove at the pit slot of ejector rod shaft bracket bottom, only by making knife plate,
Two parallel triangles are processed at the pit slot of ejector rod shaft bracket bottom hides glue groove, easy to operate, Yi Shixian, cost of manufacture
It is cheap.
The pit slot of ejector rod shaft bracket bottom increases surface roughness to after increasing hiding glue groove design from surface is smooth, can
Occur to loosen phenomenon from glue to be effectively prevented ejector rod shaft bracket.The hiding glue groove design of triangle rationally, there is enough storage spaces
Glue is stored, increases the glue-spread between ejector rod shaft bracket and interlocking bar, ejector rod shaft bracket is securely attached in interlocking bar groove
It plays an important role.
Other than the mode that above-described embodiment refers to, the top surface and side of pit slot can also be arranged in hiding glue groove, or only
The side of pit slot is set.Hiding glue groove is the slot of other shapes structure not yet, these mapping modes are in the utility model
In protection scope.
Above-described embodiment is the preferable embodiment of utility model, but the embodiments of the present invention is not by above-mentioned reality
Apply the limitation of example, it is made under other any spiritual essence and principles without departing from the utility model change, modification, substitution,
Combination simplifies, and should be equivalent substitute mode, is included within the protection scope of the utility model.
