Description
Technical field
The utility model belongs to measurement verifying attachment technical field, is related to a kind of measuring device hold-down mechanism, and in particular to
A kind of constant force hold-down mechanism.
Background technique
It is all much directly to have sale in the market, but in the market currently, measuring device hold-down mechanism common structure
Hold-down mechanism is typically all to compress production workpiece by Rubber end, and measured workpiece is fixed pressure after pressing device enters self-locking state
Tightly, but it is higher for the status requirement of installation, if installation site is bad, it is easy to just rubber squeeze head is damaged by pressure, it is then general
It presses part to easily lead to part deformation damage in logical pressing device use process firmly, needs to replace hold-down mechanism in time, increase
Manufacture production cost, reduces production efficiency；And pressing device fails, and is increased by the risk of detection failure.
Summary of the invention
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of durability it is good, it is easy to operate,
The constant force hold-down mechanism of high-efficient measuring device.
According to the technical solution of the utility model, the constant force hold-down mechanism, including compressing structure, pressure head, spring and lock
Tight part, the compressing structure include pedestal, handle and compression bar, and one end of compression bar is articulated on pedestal, and the lower part of handle is across pressure
Bar is articulated on pedestal, and the middle part of handle is equipped with convex block；The upper end of the pressure head passes through the through-hole of the compression bar other end and utilizes lock
Tight part locking, the lower end of pressure head is cased with spring between briquetting and compression bar.
Further, the locking member is interlocking two hex nuts.
The utility model has the beneficial effects that: spring and locking member are replaced on original compressing structure using self-control pressure head
Rubber pressure head, it is not easy to wear using easy, quick, can guarantee substantially increase hold-down mechanism while compressing intensity
Service life.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the left view of Fig. 1.
Description of symbols: 1- compressing structure, 11- pedestal, 12- handle, 13- compression bar, 14- convex block, 2- pressure head, 3- bullet
Spring, 4- locking member.
Specific embodiment
The utility model is described in further detail with attached drawing combined with specific embodiments below.
It is as shown in the figure: the utility model constant force hold-down mechanism, including compressing structure 1, pressure head 2, spring 3 and locking member 4, pressure
Locking structure 1 includes pedestal 11, handle 12 and compression bar 13, and 13 one end of compression bar is articulated on pedestal 11, and the lower part of handle 12 is across pressure
Bar 13 is articulated on pedestal 11, and the middle part of handle 12 is equipped with convex block 14, and the height of convex block 14 is higher than compression bar 13.The upper end of pressure head 2
Through-hole and utilization locking member 4 across 13 other end of compression bar are locked, and the lower end of pressure head 2 is cased with spring between briquetting and compression bar 13
3。
Specifically, locking member 4 is interlocking two hex nuts, at low cost, materials are convenient.
The course of work and principle: two hex nuts of locking member 4 tighten interlocking, and driving handle 12 compresses compression bar 13, benefit
Required part is compressed with pressure head 2, impaction state is completed when the convex block 14 of compressing structure 1 reaches A point self-locking position, convex block 14 is pressed
Firmly compression bar 13, at this moment spring 3 is compressed, and plays pressuring action.
General outsourcing compressing structure is all using rubber squeeze head, and rubber squeeze head is easy aging or damage, then compresses knot
The flexible adjustment ability of structure disappears, and is difficult to adjust the pressure of part, once the adjusting of compressing structure position is improper, just will appear pressure not
To or self-locking position A point is not achieved, be unable to complete compression, compressing by force just will appear B point and be stretched, and compressing structure is destroyed
The case where occur.The utility model compressing structure 1 when the convex block 14 of compressing structure 1 reaches A point self-locking position reaches compression shape
State, convex block 14 push down compression bar 13, and at this moment spring 3 is compressed, and protection compressing structure 1 avoids it from becoming when by immense pressure
Shape damage, while but also compressing component by constant pressure, plays the role of protecting part.
