[0023] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0024] See also Figures 1 to 4 As shown, a plantar pressure analyzer includes a weighing plate 1, a data processor 2, an unwinding assembly 3, a winding assembly 4, an unwinding roller 5, a winding roller 7, a dustproof film 6 and a power unit 8. The weighing plate 1 is a prior art, and is equipped with a pressure sensing system for detecting the plantar pressure distribution, which will not be described in detail here. The data processor 2 is fixed on one side of the weighing plate 1, and is used to transmit the detected pressure data to an external intelligent device (such as a computer). Preferably, a handle 21 is provided on the side of the data processor 2 away from the weighing plate 1 to facilitate the taking of the plantar pressure analyzer. The unwinding assembly 3 and the winding assembly 4 are fixed on the top surface of the weighing plate 1. Because the plantar pressure distribution of the tested person in the standing state and the walking state needs to be detected during the process, therefore, in this embodiment, the unwinding assembly 3 and the winding assembly 4 are respectively located on the side close to the data processor 2 and the side away from the data processor 2, that is, the unwinding assembly 3 and the winding assembly 4 are respectively located on the left and right sides of the tested person, to facilitate the test.

[0025] The unwinding roller 5 is rotatably connected inside the unwinding assembly 3, the winding roller 7 is rotatably connected inside the winding assembly 4, the dustproof film 6 is wound around the outside of the unwinding roller 5, one end of the dustproof film 6 extends toward the winding roller 7 and is wound around the winding roller 7, and the power unit 8 is fixed on one side of the weighing plate 1 to drive the winding roller 7 to rotate. It should be noted that one end of the dustproof film 6 is wound around the winding roller 7 in advance by the staff before the test, so that the feet of the test subject are in contact with the dustproof film 6 during the test.

[0026] During implementation, when a person being tested has completed the test, the power unit 8 is started, and the power unit 8 drives the winding roller 7 to rotate. During the rotation of the winding roller 7, the dust-proof film 6 is pulled and wrapped around the outside of the winding roller 7. At the same time, the unwinding roller 5 is rotated by the pulling of the winding roller 7, and the dust-proof film 6 on the outside of the unwinding roller 5 is released until the dust-proof film 6 on which the last person being tested has stood is completely wrapped around the winding roller 7, and then the power unit 8 stops rotating. At this time, the top surface of the weighing plate 1 is a brand new, unused dust-proof film 6, so as to test the next person being tested. By setting the unwinding roller 5, the winding roller 7, the dust-proof film 6 and the power unit 8, the dust-proof film 6 on the top of the weighing plate 1 is immediately updated after each test is completed, thereby avoiding the problem of cross-infection of foot bacteria.

[0027] The winding assembly 4 and the unwinding assembly 3 each include two fixed blocks 31 disposed at intervals and a cover plate 32 covering the top of the two fixed blocks 31. The two fixed blocks 31 are respectively located on both sides of the width direction of the weighing plate 1. The axial ends of the unwinding roller 5 and the winding roller 7 are respectively rotatably connected between the corresponding fixed blocks 31 and the cover plate 32. Figure 2 As shown, the top surface of the fixing block 31 is provided with a lower groove 314, the bottom surface of the cover plate 32 is provided with an upper groove 321, and one end of the unwinding roller 5 or the winding roller 7 is rotatably connected between the corresponding upper groove 321 and the lower groove 314. In this embodiment, the cover plate 32 is fixedly connected to the fixing block 31 by bolts 322 for easy disassembly.

[0028] In this embodiment, the power unit 8 includes a first motor 81 fixedly mounted on one side of the weighing plate 1, a first transmission wheel 82 is sleeved on the output end of the first motor 81, one end of the winding roller 7 passes through the winding assembly 4 and extends toward the first motor 81, and a second transmission wheel 83 is fixedly sleeved thereon, and the first transmission wheel 82 and the second transmission wheel 83 are connected by a belt 84. The belt 84 is used to facilitate the staff to replace the winding roller 7.

[0029] like Figure 4As shown, in this embodiment, the winding assembly 4 and the unwinding assembly 3 are respectively provided with a clamping portion 9 for making the dustproof film 6 fit with the top surface of the weighing plate 1, and the clamping portion 9 is respectively located on the opposite side of the winding assembly 4 and the unwinding assembly 3. The clamping part 9 includes a pressing roller 91, a threaded column 92 and a spring 93, wherein the opposite surfaces of the two fixed blocks 31 are the inner surfaces, and a threaded hole 311 is vertically opened on each fixed block 31, and a through groove 312 connected to the outside is vertically arranged on the side of each threaded hole 311 close to the inner surface, and the two ends of the pressing roller 91 extend into the threaded hole 311 through the corresponding through grooves 312 respectively, and are slidably connected with the through grooves 312, and the threaded column 92 is screwed on the top of the threaded hole 311, and the spring 93 is arranged inside the threaded hole 311, and the two ends of the spring 93 are respectively in contact with the pressing roller 91 and the threaded column 92, so that the pressing roller 91 is moved toward the direction close to the weighing plate 1 through the spring 93, thereby making the dustproof film 6 fit the top surface of the weighing plate 1.

[0030] During implementation, the staff passes the two ends of the pressing roller 91 through the corresponding through grooves 312 and places them in the threaded holes 311, then puts in the spring 93, and then screws the threaded column 92 on the threaded holes 311, at which time one side of the pressing roller 91 abuts against the top surface of the weighing plate 1. It should be noted that when the staff needs to wind one end of the dust-proof film 6 on the outside of the unwinding roller 5 on the winding roller 7, the staff needs to lift the two pressing rollers 91 upward in turn, pass one end of the dust-proof film 6 from the bottom of the pressing roller 91, and then wind one end of the dust-proof film 6 on the outside of the winding roller 7. When the staff releases the pressing roller 91, the pressing roller 91 is pressed against the dust-proof film 6 by gravity plus the elastic force of the spring 93, and then the dust-proof film 6 is attached to the top surface of the weighing plate 1.

[0031] By respectively setting a pressing roller 91 in the unwinding assembly 3 and the winding assembly 4, the dustproof film 6 is fitted with the top surface of the weighing plate 1, so as to facilitate the test by the tested personnel, and at the same time prevent the dustproof film 6 from warping and interfering with the test. By setting a threaded column 92, the staff can adjust the screw connection height between the threaded column 92 and the threaded hole 311, and then adjust the pressure of the spring 93 on the pressing roller 91. Preferably, each fixed block 31 is provided with an installation groove 313, and the threaded hole 311 is provided in the installation groove 313. This is to make way for the cover plate 32 and facilitate the operation of the staff.

[0032] When the utility model is implemented, the staff places the unwinding roller 5 with the dustproof film 6 in the lower groove 314 of the two corresponding fixing blocks 31, and then covers the cover plate 32 and fixes it by bolts 322. At this time, the unwinding assembly 3 is installed, and the winding assembly 4 is installed using the same method. After the installation is completed, the staff lifts the two pressing rollers 91 in turn, and pulls one end of the dustproof film 6 at the same time, so that one end of the dustproof film 6 passes under the two pressing rollers 91 and moves toward the winding assembly 4, and then winds one end of the dustproof film 6 around the winding roller 7. After the dustproof film 6 is installed, the staff sets the belt 84 on the outside of the first transmission wheel 82 and the second transmission wheel 83 to complete the transmission connection between the power unit 8 and the winding roller 7. When in use, by setting the unwinding roller 5, the winding roller 7, the dustproof film 6 and the power unit 8, the dustproof film 6 on the top of the weighing plate 1 is immediately updated after each test is completed to avoid the problem of cross-infection of bacteria on the feet of multiple tested persons.

[0033] The above description is only a preferred embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
