[0027] Embodiment

[0028] Refer to Figures 1-4 For an embodiment of the utility model, a tension rope displacement type deflection meter is provided, which comprises a measurement unit 100 and a detection unit 200.

[0029] The measurement unit 100 comprises a deflection meter 101, and a rope 102 is stretched from the inside of the deflection meter 101 on one side of the deflection meter 101.

[0030] The detection unit 200 comprises a ring-shaped cover 201 sleeved on the rope 102, a copper ring 202 fixedly sleeved on the side wall of the ring-shaped cover 201, an electrode column 203 fixedly connected to the side wall of the copper ring 202, a buzzer 204 fixedly connected to the end of the electrode column 203, a plurality of copper columns 205 fixedly connected to the inner wall of the ring-shaped cover 201, the end of each copper column 205 penetrating through the ring-shaped cover 201 and fixedly connected to the copper ring 202, a copper ring 206 arranged at the center of the inside of the ring-shaped cover 201, a plurality of springs 207 fixedly connected to the inner wall of the ring-shaped cover 201 away from the copper ring 206, and a support assembly 209 for fixing the ring-shaped cover 201.

[0031] When measuring an object, the deflection meter 101 is fixed at a fixed position, then the ring-shaped cover 201 is fixed in the horizontal direction or the vertical direction by the support assembly 209, then the rope 102 is passed through the copper ring 206 and fixed on a moving object, then the rope 102 can be pulled for measurement, when the rope 102 is pulled in the horizontal or vertical direction, it is necessary to ensure that the rope 102 is located at the axis of the copper ring 206, the side wall of the copper ring 206 is fixedly connected to three springs 207 distributed at equal intervals in a ring shape, the copper ring 206 is suspended at the center of the ring-shaped cover 201 by the springs 207, when the rope 102 occurs sagging or yawing movement, the rope 102 pulls the copper ring 206, so that the copper ring 206 moves in the direction of pulling, when the amplitude of the rope 102 is too large, the copper ring 206 contacts the copper column 205 in the corresponding direction.

[0032] At this time, the copper ring 206 is connected with the electrode column 203 through the copper column 205 and the copper ring 202, the electrode column 203 is electrically connected with the buzzer 204, the buzzer 204 can be internally or externally powered, the buzzer 204 is connected with the electrode column 203 and the wire 208, and the buzzer 204 can emit a sound to remind the user, so that the user can correct the rope 102 in time to reduce errors, when the rope 102 is corrected, the copper ring 206 is no longer stressed and is reset by the spring 207, the reset copper ring 206 no longer contacts the copper column 205, the buzzer 204 stops emitting a sound, and the copper ring 206 can be a switch of the buzzer 204 through the rope 102 to assist the user to improve the measurement accuracy.

[0033] Specifically, the support assembly 209 includes a T-shaped threaded sleeve 2091 fixedly connected to one side of the annular cover 201, one end of the T-shaped threaded sleeve 2091 is threadedly connected with a threaded column 2092, one end of the threaded column 2092 is fixedly connected with a support rod 2093, and the side wall of the support rod 2093 is fixedly sleeved with two flange plates 2094.

[0034] When the rope 102 is horizontally stretched, the threaded column 2092 is connected to the bottom end of the T-shaped threaded sleeve 2091, and when the rope 102 is vertically stretched, the threaded column 2092 is connected to the end away from the annular cover 201, so as to fixedly connect the annular cover 201 according to different measurement modes, the support rod 2093 is used for supporting the annular cover 201, a plurality of support rods 2093 can be fixedly connected through the flange plates 2094 and bolts to increase the height of the support, and the support rod 2093 at the end is fixed to a corresponding ground base or support base through a bolt, so that the annular cover 201 can be raised by an external base when the height of the annular cover 201 and the rope 102 have a difference, to ensure that the rope 102 is located at the center of the copper ring 206.

[0035] In addition, a plurality of threaded holes are formed in one side of the copper ring 206, and two semicircular plates 210 are fixedly connected to one side of the copper ring 206 through bolts.

[0036] The two semicircular plates 210 can form a circular ring, and the inner diameter of the circular ring is smaller than that of the copper ring 206, when the rope 102 sags or swings, the rope 102 can drive the copper ring 206 to move through the semicircular plates 210, so that the buzzer 204 emits a sound when the rope 102 moves slightly, the inner diameter of the semicircular plate 210 can be reduced according to the situation, and the smaller the inner diameter of the semicircular plate 210, the easier the buzzer 204 is triggered, so as to be suitable for detailed and high-precision measurement, when only rough measurement is required, the semicircular plate 210 is removed through the bolt, so that the buzzer 204 is not triggered by the slight movement of the rope 102, thereby facilitating efficient rough measurement.

[0037] Further, a plurality of rulers 211 are fixedly connected to one side of the ring-shaped cover 201, the plurality of rulers 211 are arranged in a ring shape at equal intervals, and a plurality of straight plates 212 corresponding to the rulers 211 are fixedly connected to one side of the copper ring 202. Each straight plate 212 is in contact with the corresponding ruler 211.

[0038] The ruler 211 is made of transparent material and is used to detect the position of the copper ring 206. When the copper ring 206 is used for a long time or is damaged, the position of the copper ring 206 can be measured by the ruler 211. Whether the copper ring 206 is located at the center of the ring-shaped cover 201 can be measured by the rulers 211 at different positions, so as to ensure the accuracy of the copper ring 206 itself. The straight plate 212 is aligned with the scale line of each ruler 211, so as to facilitate the observation of the verticality of the scale line on the ruler 211 by the straight plate 212, thereby judging whether the copper ring 206 is deviated, so as to facilitate the subsequent correction or replacement of part of the parts of the copper ring 206.

[0039] Further, the top and one side of the deflection meter 101 are fixedly connected with a level bubble 103, and the two level bubbles 103 are vertically distributed.

[0040] When the deflection meter 101 is installed horizontally, the top level bubble 103 can detect whether the deflection meter 101 is horizontal. When the deflection meter 101 is installed vertically, the level bubble 103 on one side can detect whether the deflection meter 101 is in a vertical state, so as to improve the accuracy of measurement.

[0041] During use, the threaded column 2092 is connected to the corresponding end of the T-shaped threaded sleeve 2091 according to the direction of measurement. The plurality of support rods 2093 can be fixedly connected by flanges 2094 and bolts to increase the height of the support. The support rod 2093 at the end is fixed to the corresponding base or support seat by bolts. Then the deflection meter 101 is fixed at the fixed position. Then the rope 102 is passed through the copper ring 206 and fixed to the moving object. The level bubble 103 can detect whether the deflection meter 101 is fixed correctly. Then the rope 102 can be pulled to measure. When the rope 102 is inclined or the deflection amplitude is too large, the rope 102 pulls the copper ring 206 to contact the copper column 205 in the corresponding direction. At this time, the copper ring 206 is connected to the circuit of the electrode column 203 by the copper column 205 and the copper ring 202. The buzzer 204 can be internally powered or externally powered.

[0042] The buzzer 204 is connected to the electrode column 203 and the wire 208, and then the buzzer 204 can emit a sound to remind the user, so that the user can correct the rope 102 in time to reduce the error, when the rope 102 is corrected, the copper ring 206 is not forced and is reset by the spring 207, then the buzzer 204 stops emitting the sound, when the accuracy of the measurement needs to be improved, the two semicircular plates 210 with the same inner diameter are fixed on one side of the copper ring 206 by the bolts, thus when the rope 102 moves slightly, the buzzer 204 emits a sound, and the vertical of the scale line on the ruler 211 is observed by the straight plate 212, so as to determine whether the copper ring 206 is deviated.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, not to limit it. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, and they should be covered in the scope of the claims of the present application.
