Description
Technical field
The present invention relates to a kind of chair framework backrest and reply force test device, belong to machinery field.
Background technology
For the test of chair framework backrest restoring force, conventional method of testing is that artificial hand-held pull and push dynamometer will be treated
The chair framework backrest surveyed is to pusher, and not only the terminal of movable backrest is difficult to grasp, the dynamics of promotion and speed
Can not accomplish constant too, the efficiency causing test is low, and the error of test result is bigger.
Summary of the invention
The technical problem to be solved in the present invention is to overcome existing defect, it is provided that a kind of chair framework backrest restoring force
Test device, improves testing efficiency, it is ensured that the correctness of test result.
In order to solve above-mentioned technical problem, the invention provides following technical scheme:
A kind of chair framework backrest replys force test device, including base, support and test execution device, support
Bottom is arranged on base, and cantilever tip is provided with test execution device；Test execution device includes matrix, company
Fitting and execution arm；The rear end of matrix connects support, and the middle part of matrix is provided with backrest lock locking mechanism, matrix
The anterior upper end with connector is fixed and is connected；The lower end of connector is fixing with the middle part performing arm to be connected, and performs arm
One end be provided with speed controlling cylinder, the other end performing arm is provided with pressure transducer；The side of connector
It is provided with mechanism action cylinder, is connected with pressure transducer.
Further, base is provided with seat cushion and changes detent mechanism.
Further, support is provided with backrest initial point induction apparatus.
One chair framework backrest of the present invention replys force test device, it is ensured that the terminal of movable backrest and promotion
Dynamics and speed, test is automatically performed, it is to avoid the unstable factor of artificial test, improves testing efficiency,
Ensure that the correctness of test result.
Accompanying drawing explanation
Accompanying drawing is for providing a further understanding of the present invention, and constitutes a part for description, with the present invention
Embodiment be used for together explaining the present invention, be not intended that limitation of the present invention.In the accompanying drawings:
Fig. 1 is the structural representation that a kind of chair framework backrest of the present invention replys force test device；
Fig. 2 is the partial enlarged drawing of Fig. 1；
Fig. 3 is the schematic diagram after part rotary viewing angle shown in Fig. 2.
Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are illustrated, it will be appreciated that described herein excellent
Select embodiment to be merely to illustrate and explain the present invention, being not intended to limit the present invention.
As shown in Figure 1, 2, 3, a kind of chair framework backrest replys force test device, including base 1, support
2 and test execution device, support 2 bottom is arranged on base 1, and support 2 top is provided with test execution dress
Putting, be provided with seat cushion and change detent mechanism 11 on base, on support 2, the lower section of test execution device sets
It is equipped with backrest initial point induction apparatus 3.
Test execution device includes matrix 4, connector 5 and performs arm 6；The rear end of matrix 4 connects support 2,
The middle part of matrix 4 is provided with backrest lock locking mechanism 7, and the front portion of matrix 4 is fixing with the upper end of connector 5 to be connected；
The lower end of connector 5 is fixing with the middle part performing arm 6 to be connected, and the one end performing arm 6 is provided with speed controlling gas
Cylinder 8, the other end performing arm 6 is provided with pressure transducer 9；The side of connector 5 is provided with mechanism action
Cylinder 10, is connected with pressure transducer 9.
Work process: changed detent mechanism by the seating portion positioning and locking of chair framework to be measured by seat cushion；When
Backrest initial point induction apparatus senses the backrest contact of chair framework when being i.e. in origin position, backrest lock locking mechanism to
Lower release locking backrest；Backrest is pushed back into setting position, mechanism action cylinder running band by speed controlling cylinder
Dynamic pressure sensor contacts backrest, after reading the recovery pressure value of backrest, returns to original position, simultaneously backrest lock
Locking mechanism terminates locking, returns to original position；Speed controlling cylinder returns to original position, terminates test.
In said process, the terminal of movable backrest and the dynamics of promotion, speed are all complete according to setting value by system
Become, it is ensured that Stability and veracity.When test, recovery pressure value that test can be obtained by system and setting
Value phase comparison, if defective, system can send alarm, and is locked by chair framework, it is simple to operator finds not
Qualified products, process in time.
One chair framework backrest of the present invention replys force test device, it is ensured that the terminal of movable backrest and promotion
Dynamics and speed, test is automatically performed, it is to avoid the unstable factor of artificial test, improves testing efficiency,
Ensure that the correctness of test result.
Last it is noted that the foregoing is only the preferred embodiments of the present invention, it is not limited to this
Invention, although being described in detail the present invention with reference to previous embodiment, for those skilled in the art
For, the technical scheme described in foregoing embodiments still can be modified by it, or to wherein part
Technical characteristic carries out equivalent.All within the spirit and principles in the present invention, any amendment of being made, equivalent
Replacement, improvement etc., should be included within the scope of the present invention.
