Embodiment
The utility model is described in detail below in conjunction with specific embodiment and accompanying drawing.
A kind of wire wound resistor of the present embodiment, as illustrated in fig. 1 and 2, including base tube 1, be fixed on base tube 1 both ends branch
Frame 2 and the latch assembly 3 for being located at the end of base tube 1, the support 2 at the both ends of base tube 1 is respectively by different latch assemblies 3 come independent
Base tube 1 is fixed on ground.As shown in Figure 3 and Figure 4, latch assembly 3 includes threaded adjusting bar 31, axial moving piece 32 and two pieces of locking members
33, Fig. 4 be the stereogram of one piece of locking member 33, and every piece of locking member 33 includes the integrally formed connection sheet 331 of punching press and two pieces
Flexure strip 332, two pieces of flexure strips 332 are respectively positioned at the both ends of connection sheet 331 so as to forming the lock for the U-shaped that outward opening struts
Tight part 33, the connection sheet 331 of two pieces of locking members 33 are laminated, and the flexure strip 332 of two pieces of locking members 33 is axially visually mutually wrong
Arrangement is opened, connection sheet 331 and axial moving piece 32 are arranged in juxtaposition.Two pieces of locking members can be formed in one in practice, i.e., and one
Four sides of bump contacted chip each extend over flexible.Threaded adjusting bar 31 sequentially passes through connection sheet 331 and axial moving piece 32, axle
Be threadedly coupled between moving member 32 and threaded adjusting bar 31, flexure strip 332 threadingly adjusting rod 31 angled radially outward and
Elasticity collapses prop up axial moving piece 32 inwardly.During assembling, the driving axial moving member 32 of rotation threaded adjusting bar 31 moves axially
While, as shown in Fig. 2 axial moving piece 32 radially promotes the inclined plane of flexure strip 332 inwardly to strut elasticity outward
Piece 332 pushes against the madial wall of base tube 1, so as to realize the fixation between support 2 and base tube 1.As shown in figure 5, axially moved in Fig. 3
The stereogram that moving part 32 turns around, the week side of boss of axial moving piece 32 are to touch the lozenges 321 of flexure strip 332, are easy to axial shifting
Moving part 32 touch flexure strip 332 and moved.
Compared with prior art, a kind of wire wound resistor of the present embodiment, traditional screw rod through base tube 1 is eliminated,
The support 2 at the both ends of base tube 1 is fixed on base tube 1, identical latch assembly 3 by different latch assemblies 3 come independent respectively
The base tube 1 of different length can be applied to, assembling is convenient, reduces production cost.Even if the end of base tube 1 need in addition combined with
Ceramics carrys out fixed support 2, due to eliminating the internal stress of classic screw, can effectively avoid assembling and using process porcelain
The problem of piece ruptures.
In practice, as long as the support 2 at the both ends of base tube 1 can be realized respectively by different latch assemblies 3 come independently solid
Determine base tube 1, in above example, locking member 33 is to strut the inwall for pushing against base tube 1 after being operated by operating personnel again.Make
For another embodiment of the present utility model, pushing against compressed be in before part enters substrate tube can move in base inner axial tube
Rounding state, when needing fixed support, operating personnel, which operate, releases compression to locking member, and locking member will strut abutting
The locking state of base tube inwall, it so can also realize the purpose that the utility model is created.
In practice, threaded adjusting bar is driven axial moving piece axial movement by operating personnel's rotation process, and lock is promoted with this
The embodiment that tight part radially struts, in addition to using above-mentioned flexure strip, structure in detail below, locking can also be used
Part is a resilient sleeve, and axial moving piece is a bullet, and the less one end insertion of diameter of axial moving piece is locked
In part, when needing fixed support with base tube, rotation threaded adjusting bar drives axial moving piece movement so that axial moving piece
The one end being relatively large in diameter enters in locking member the purpose that so as to strut locking member, so can also realize that the utility model is created.
Finally it should be noted that above example is only illustrating the technical solution of the utility model, rather than to this reality
With the limitation of novel protected scope, although being explained with reference to preferred embodiment to the utility model, this area it is general
It is logical it will be appreciated by the skilled person that can be modified to the technical solution of the utility model or equivalent substitution, without departing from this
The spirit and scope of utility model technical scheme.
