The rear end of the base body is connected with the support, the central part of the base body is provided with a backrest locking mechanism, and the front part of the base body is fixedly connected with the upper end of the connecting piece. The lower end of the connecting piece is fixedly connected with the central part of the executing arm. One end of the executing arm is provided with a speed control cylinder, and the other end of the executing arm is provided with a pressure sensor. A side surface of the connecting piece is provided with a mechanism operation cylinder which is connected with the pressure sensor. The device provided by the utility model guarantees the starting and stopping points of the backrest, the force and speed of pulling, and the automatic testing. The device avoids the unstable factors of manual testing, improves the testing efficiency, and guarantees the accuracy of test results.
Description
Technical field
The utility model relates to a kind of chair framework backrest restoring force proving installation, belongs to mechanical hook-up field.
Background technology
Test for chair framework backrest restoring force, conventional method of testing be artificial hand-held pull and push dynamometer by chair framework backrest to be measured to pusher, not only the terminal of movable backrest is difficult for grasping, the dynamics and the speed that promote can not be accomplished constant too, cause the efficiency of test low, the error of test result is larger.
Utility model content
The technical problems to be solved in the utility model is to overcome existing defect, and a kind of chair framework backrest restoring force proving installation is provided, and improves testing efficiency, guarantees the correctness of test result.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
A chair framework backrest restoring force proving installation, comprises base, support and test execution device, and support bottom is arranged on base, and cantilever tip is provided with test execution device; Test execution device comprises matrix, web member and execution arm; The rear end connection bracket of matrix, the middle part of matrix is provided with backrest lock locking mechanism, and the front portion of matrix is fixedly connected with the upper end of web member; The lower end of web member is fixedly connected with the middle part of carrying out arm, and the one end of carrying out arm is provided with speed control cylinder, and the other end of carrying out arm is provided with pressure transducer; The side of web member is provided with mechanism action cylinder, is connected with pressure transducer.
Further, on base, be provided with seat cushion and change detent mechanism.
Further, on support, be provided with backrest initial point inductor.
A kind of chair framework backrest restoring force of the utility model proving installation, guarantee the terminal of movable backrest and the dynamics of promotion and speed, test completes automatically, has avoided the labile factor of artificial test, improve testing efficiency, guaranteed the correctness of test result.
Accompanying drawing explanation
Accompanying drawing is used to provide further understanding of the present utility model, and forms a part for instructions, is used from explanation the utility model with embodiment mono-of the present utility model, does not form restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the structural representation of a kind of chair framework backrest restoring force of the utility model proving installation;
Fig. 2 is the partial enlarged drawing of Fig. 1;
Fig. 3 is the schematic diagram behind the visual angle of partial rotation shown in Fig. 2.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for description and interpretation the utility model, and be not used in restriction the utility model.
As shown in Figure 1, 2, 3, a kind of chair framework backrest restoring force proving installation, comprise base 1, support 2 and test execution device, support 2 bottoms are arranged on base 1, support 2 tops are provided with test execution device, on base, be provided with seat cushion and change detent mechanism 11, on support 2 test execution device below be provided with backrest initial point inductor 3.
Test execution device comprises matrix 4, web member 5 and carries out arm 6; The rear end connection bracket 2 of matrix 4, the middle part of matrix 4 is provided with backrest lock locking mechanism 7, and the front portion of matrix 4 is fixedly connected with the upper end of web member 5; The lower end of web member 5 is fixedly connected with the middle part of carrying out arm 6, and the one end of carrying out arm 6 is provided with speed control cylinder 8, and the other end of carrying out arm 6 is provided with pressure transducer 9; The side of web member 5 is provided with mechanism action cylinder 10, is connected with pressure transducer 9.
The course of work: change detent mechanism by the seat cushion part positioning and locking of chair framework to be measured by seat cushion; When backrest initial point inductor senses that the backrest of chair framework contacts in origin position, backrest lock locking mechanism is released locking backrest downwards; Speed control cylinder is shifted backrest onto desired location backward, and the running of mechanism action cylinder drives pressure transducer contact backrest, reads after the recovery pressure value of backrest, gets back to reference position, and backrest lock locking mechanism finishes locking simultaneously, gets back to reference position; Speed control cylinder is got back to reference position, finishes test.
In said process, the terminal of movable backrest and the dynamics of promotion, speed are all completed according to setting value by system, have guaranteed Stability and veracity.When test, recovery pressure value and setting value that system can obtain test compare, if defective, system can give the alarm, and by chair framework locking, are convenient to operator and find substandard product, process in time.
A kind of chair framework backrest restoring force of the utility model proving installation, guarantee the terminal of movable backrest and the dynamics of promotion and speed, test completes automatically, has avoided the labile factor of artificial test, improve testing efficiency, guaranteed the correctness of test result.
Finally it should be noted that: the foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, although the utility model is had been described in detail with reference to previous embodiment, for a person skilled in the art, its technical scheme that still can record aforementioned each embodiment is modified, or part technical characterictic is wherein equal to replacement.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
