The force applying devices 400 respectively apply an acting force to two end corners of the top of the television, and the two acting forces are perpendicular to the plane of the television and opposite in direction; it should be noted that the present application does not limit the structure of the force application device 400, and it should be within the scope of the present application as long as the force application device 400 can apply a force to the two end corners of the top of the tv respectively, and the two forces are perpendicular to the plane of the tv and opposite in direction.
The measuring device 300 measures the amount of deformation of the television in the direction of the two applied forces, respectively. Likewise, the application is not limited to the specific structure of the measuring device 300.
When the television supporting device works, the supporting device 200 supports and fixes two end corner parts at the bottom of the television and clamps, limits and fixes the two end corner parts in the direction vertical to the plane of the television; then, the force applying device 400 applies force to the two end corners of the top of the television, and the deformation of the television is measured by the measuring device 300. Therefore, the measuring clamp provided by the application can measure two end corner parts, only two manpower are needed to apply acting force on the force application device 400, and the manpower is saved. In addition, since the supporting device 200 enables the television to be vertically placed, the reliability of the measurement data can be improved compared to the horizontal placement in the prior art. In addition, in the present application, the deformation of the television is directly measured by the measuring device 300, and manual conversion is not needed, so that the measurement is convenient and labor-saving.

As shown in fig. 3, the supporting device 200 includes two base members which support two end corners of the bottom of the fixed tv, respectively. Of course, the supporting device 200 may be a unitary structure, and both ends of the unitary structure support both end corners of the bottom of the tv.

In the technical scheme, the television can be vertically fixed conveniently through the structural design of clamping of the two clamping pieces, and the clamping is limited conveniently in the direction perpendicular to the plane of the television, so that two purposes are achieved at one stroke.
It should be noted that, in any technical solution of the present application, the plane of the television refers to the plane of the television display screen, and thus the direction perpendicular to the plane of the television refers to the direction perpendicular to the television display screen.
In the above structure, a specific design may also be made. For example, as shown in fig. 3, the first clip 201 is fixed to the base body 203; the base body 203 is provided with a guide positioning groove 203a, and the second clamping piece 202 is provided with a guide positioning protrusion 202a matched with the guide positioning groove 203a, so that the second clamping piece 202 can slide relative to the base body 203, and the distance between the second clamping piece 202 and the first clamping piece 201 can be adjusted.
In the above structure, due to the design of the guide positioning groove 203a, the second clip sheet 202 can slide along the guide positioning groove 203a by virtue of the guide positioning protrusion 202a, so as to adjust the distance between the second clip sheet 202 and the first clip sheet 201, thereby being capable of adapting to the measurement requirements of televisions with different thicknesses and sizes.
In addition, in the above technical solution, the base member may be specifically designed. For example, as shown in fig. 3, in order to increase the stability of the connection between the first jaw 201 and the base body 203, a reinforcing rib 204 may be provided to connect between the first jaw 201 and the base body 203, thereby improving the stability of the connection.
In addition, as shown in fig. 3, when the second clip 202 is moved to a position to clamp the tv with the first clip 201, the first clip 201 and the second clip 202 can be fastened by using the bolt 206. Specifically, as shown in fig. 3, three bolts 206 may be used in a triangular arrangement to improve the stability of the bolted connection.
Furthermore, as shown in fig. 3, a positioning block is further disposed on the inner side wall of the first clip 201, and when the tv is clamped between the first clip 201 and the second clip 202, the positioning block abuts against the side end surface of the tv, so as to further limit the tv.
In addition, the base body 203 may be a weighted base, which may have sufficient weighted weight to improve the stability of the vertical support of the television.
In conclusion, the base body 203 is a counterweight base and is provided with a certain weight to ensure the stability of the clamp during measurement, the positioning block is used for reliably positioning the tested television, the two clamping pieces are used for clamping the tested television, the first clamping piece 201 is fixed, the second clamping piece 202 moves in the guide positioning groove 203a of the counterweight base body 203, and the clamping pieces are automatically adjusted to clamp the tested television by the design of the guide positioning groove 203a so as to adapt to models with different thicknesses; the clamping piece is fixedly connected with the base body 203 through three fastening bolts and matched with the positioning block, and reliable clamping and positioning of the measurement television are finally realized; all parts of the figure show are connected through bolts, can realize quick assembly and disassembly, and are convenient to have enough to meet the need, so that the technical effects of the base part are respectively discussed as follows:

secondly, the base is provided with a guiding and positioning chute, so that the guiding and positioning functions of the clamping piece are realized, the clamping piece is prevented from rotating, and the clamping reliability is ensured;
thirdly, designing three bolt fastening sites according to the clamping stress of the clamp, and performing three-point positioning and clamping;
fourthly, all parts are connected through bolts 206, and the portable detachable assembly is realized, so that the processing process is low in complexity and the manufacturing cost is low.
In any of the above embodiments, as an example, the measuring device 300 may be specifically designed. For example, referring to fig. 4, fig. 5 and fig. 6, fig. 4 is a schematic structural diagram of the measuring apparatus 300 of the measuring fixture of fig. 1; FIG. 5 is a front view of the slide 306 of the measuring device 300 of FIG. 4; fig. 6 is a top view of the slide 306 of the measuring device 300 of fig. 4.
As shown in fig. 1, the measuring apparatus 300 includes two measuring parts that respectively measure the amount of deformation of the television that occurs in the directions of the two applied forces. Of course, the same measuring component can be designed, and two different measuring modules can complete the same function, which is not limited in the present application. It should be noted that, the two measuring components are used for measuring respectively, so that the flexibility of measurement is high, and the measurement can be adjusted independently.
Further, as shown in fig. 4, in the structure of one measuring part, the measuring part includes two vertically placed brackets 301, a measuring scale 302 fixed on the two brackets 301, and a measuring block 303 movably placed on the measuring scale 302; the measuring block 303 moves on the measuring ruler 302 as the end corners of the top of the television deform.
In the above structure, as shown in fig. 1, one holder 301 is connected to one end of a measuring ruler 302 by two vertically placed holders 301, thereby making the measuring structure very stable. The measuring block 303 is provided on the measuring scale 302 and as the television deforms, the measuring block 303 can be moved on the measuring scale 302 and then read the distance of movement on the measuring scale 302. Therefore, the deformation of the television can be conveniently and directly read, and manual conversion is avoided.
In the above structure, the end corner portion of the tv top is deformed to move the measuring block 303, and thus the interlocking structure thereof is important. In the present application, as an example, a linkage structure may be specifically designed. Of course, other types of linkage structures, as long as they can deform the tv to move the measuring block 303, should be within the scope of the present application.
As shown in fig. 2 and 4, the measuring unit further comprises a movable transmission bar 304, one end of the movable transmission bar 304 is connected to the measuring block 303, and the other end thereof abuts against the side of the end corner of the top of the tv. As shown in fig. 2 and 4, the portion of the transmission rod 304 contacting the tv is provided with a circular part, and this structural design on one hand avoids the transmission of force from damaging the tv surface, and on the other hand has better adjustment performance, so that the transmission performance is better.
Furthermore, as shown in fig. 4, the transmission rod 304 passes through the measuring block 303 through a perforation, and the transmission rod 304 is locked with the measuring block 303 by the fastening block 305. When the adjustment is needed, the fastening block is loosened, and the position between the transmission rod 304 and the measurement block 303 is adjusted.
In conclusion, the measuring scale 302 is rigidly connected with the transmission rod 304 through the fastening block and is placed in the sliding block 306, the rigid connection assembly of the measuring scale 302, the fastening block and the transmission rod 304 can slide back and forth in the guide groove 306b of the sliding block 306 without obstacles, the fastening block is adjusted to enable the zero position of the measuring scale 302 to be flush with the end face of the sliding block 306 for facilitating data reading during measurement, when the transmission rod 304 moves forwards, the measuring scale 302 does not slide in the guide groove 306b, a measurer directly reads the moving data of the measuring scale 302 to obtain the torsion of the tested television, and the measuring scale is high in operability and reliability.
The technical effects are respectively explained as follows:
the first and the second fastening blocks can slide and adjust left and right on the measuring scale 302, so as to be adaptive to televisions with different specifications and types;
secondly, the adjustable measuring scale 302 is matched with the transmission rod 304 for use, and the measured deformation value is directly read without manual conversion;
thirdly, according to the specification of the purchasing measuring scale 302, a guide groove 306b is designed, and the measuring scale 302 can slide back and forth without obstacles;
fourth, the guide groove 306b designs into special-shaped cross section, and inside steel chi and recess clearance fit conveniently slide, and upper and lower port department steel chi and recess transition fit both realize that the steel chi is reliably fixed and convenient the dismantlement.
Note that, when performing measurement, there are two ways: one is that the measuring block 303 and the measuring scale 302 are rigidly connected, the television deforms, the measuring block 303 and the measuring scale 302 move under the driving of the driving rod 304, and therefore the deformation data can be determined according to the moving distance of the measuring scale 302. Alternatively, the ruler 302 is fixed, the measuring block 303 can slide relative to the ruler 302, and thus the television is deformed, and the measuring block 303 slides over the ruler 302 to read the data.
In any of the above technical solutions, further improvements can be made. For example, as shown in fig. 5 and 6, the measuring member further includes a slider 306 movably disposed on the bracket 301, and the measuring tape 302 is connected to the slider 306. The slide block 306 is provided with a guide groove 306b, and the measuring scale 302 is movably arranged in the guide groove 306 b.
In the above structure, the sliding block 306 has the through hole 306a, so that the vertical bracket 301 passes through, and therefore the sliding block 306 can slide on the bracket 301, so as to adjust the height of the measuring device 300, and further adapt to the measurement of different height positions, and therefore the measuring requirements of televisions with different sizes can be met.
In the above structure, since the sliding block 306 is provided with the guiding groove 306b, the measuring scale 302 can slide in the guiding groove 306b, so that the position of the measuring scale 302 can be adjusted, for example, the zero scale line of the measuring scale 302 can be aligned with the measuring block 303, and thus when the television deforms, data can be directly read from the measuring scale 302.
Further, as shown in fig. 1, the relationship between the bracket 301 and the base member may be specifically designed. For example, the bracket 301 is supported and fixed to the base member. In this configuration, the support frame 301 is fixed to the base member and forms a closed loop support structure, thereby providing greater support stability.
In any of the above embodiments, the force applying device 400 may be specifically designed. For example, referring to fig. 7 and 8, fig. 7 is a schematic structural diagram of a force application device 400 of the measurement fixture in fig. 1; fig. 8 is a partially enlarged view of a portion a in fig. 7.

In this configuration, the television is twisted by hooking the television by the hook 401 and then applying a force on the link 402 on the other side. The structure has the advantages of convenient force application, simple structure and low cost.
Further, as shown in fig. 7 and 8, the force application device further includes a crank connecting rod 403 connected to the connecting rod 402, and the number of the hooks 401 is two; two hooks 401 are respectively connected to both ends of the crank link 403. The connecting rod 402 and the hook 401 are connected through the crank connecting rod 403, so that on one hand, the force application of the connecting rod 402 is more convenient, and on the other hand, the connecting rod 402 and the hook 401 are very conveniently connected.
As shown in fig. 8, the force applying device further includes a telescopic rod 404, and the hook 401 is connected to an end of the crank link 403 through the telescopic rod 404. Due to the design of the telescopic rod 404, the distance between the hook 401 and the crank connecting rod 403 can be adjusted, so that the telescopic rod can adapt to televisions with different thicknesses, and has better universality.
To sum up, the adaptive hook 401 assembly is placed at the corner of a television during measurement, one end of the connecting rod 402 is connected with the push-pull dynamometer, the other end of the connecting rod 402 is connected with the crank connecting rod 403, and the crank connecting rod 403 is connected with the circular hook 401 through the telescopic rod 404. During measurement, the round hook 401 plays a role of fixedly hanging the corner of the television, so that the corner of the television is prevented from sliding and falling off; the telescopic rod 404 can adjust the telescopic amount to adapt to the measurement of televisions with different thickness specifications; the design of the crank connecting rod 403 can change the position of the force application point of the push-pull force meter, the force application point of the push-pull force meter is concentrated on the corner point of the crank, the hook 401 is ensured to be stable and prevented from falling off, and the angle part of the television is twisted when a measurer pulls the push-pull force meter, so that the data measurement work is completed.
