Description

Technical Field

[0001] This utility model relates to the field of construction surveying equipment technology, and more specifically to a surveying tape measure structure. Background Technology

[0002] As is well known, surveying involves measuring and drawing, using measurement methods to obtain graphic and location information reflecting the current state of the ground from existing feature points and boundaries of buildings, for use in engineering construction planning, design, and administration. During this process, measuring tapes are required.

[0003] In existing measuring tape structures, workers need to continuously shake the tape during winding to prevent folding or other damage during rapid winding, which would affect its subsequent use. Furthermore, after use, dirt, dust, and other foreign matter easily adhere to the tape's surface, entering the housing during winding. When the dirt surface is moist, it can easily corrode internal components, shortening their lifespan. Dust adhering to the tape's surface can also obstruct readings, affecting usability, necessitating timely cleaning of the surface. Utility Model Content

[0007] Preferably, the extrusion assembly includes an extrusion shaft, and a transmission cavity is provided inside the housing. The transmission cavity is connected to the rotating hole and the vibration groove. The two ends of the extrusion shaft are respectively rotatably mounted on the opposite inner walls of the transmission cavity. A plum blossom extrusion wheel is fixedly installed on the peripheral outer wall of the extrusion shaft. The plum blossom extrusion wheel is in contact with the side of the vibration block.

[0013] 1. This utility model, through the rotation of the winding shaft and the meshing action of the two first sprockets and the first chain, drives the extrusion shaft and the plum blossom extrusion wheel to rotate, thereby continuously extruding the vibrating block.

[0023] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0024] Figures 1-7 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-7 The present invention will be further described below.

[0025] Specifically, a surveying measuring tape structure includes a housing 1 and a measuring tape 3. Rotating holes are provided on the inner walls of the housing 1, and a take-up shaft 4 is rotatably installed in both rotating holes. An operating lever 2 is provided at one end of the take-up shaft 4. One end of the measuring tape 3 is fixedly installed on the outer periphery of the take-up shaft 4. A smoothing component adapted to the measuring tape 3 is provided inside the housing 1. The smoothing component includes two smoothing plates 13, which are movably installed inside the housing 1. One side of each smoothing plate 13 is pointed. The two sides of the measuring tape 3 are respectively fitted to the adjacent sides of the two smoothing plates 13. A cleaning component is provided inside the housing 1, including two cleaning roller brushes 19, which are rotatably installed inside the housing 1 and rotate synchronously in opposite directions.

[0026] The smoothing assembly also includes two vibrating blocks 10. Vibration grooves are provided on the inner walls of the housing 1. Guide shafts 11 are fixedly installed on the bottom inner walls of the two vibration grooves. Guide grooves are provided on the bottom of the two vibrating blocks 10. The two guide shafts 11 are slidably installed in the two guide grooves. Return springs 12 are sleeved on the outer walls of the two guide shafts 11. The sides of the two vibrating blocks 10 that are close to each other are fixedly connected to the two sides of the two smoothing plates 13. Two pressing assemblies are provided inside the housing 1. The pressing assemblies are used to drive the vibrating blocks 10 to reciprocate up and down through the rotation of the winding shaft 4. Through the reciprocating vibration of the two vibrating blocks 10, the two smoothing plates 13 can be driven to vibrate synchronously, thereby shaking the tape measure 3 during the winding process, thus effectively avoiding the tape measure 3 from folding during the winding process and improving the winding effect.

[0027] The extrusion assembly includes an extrusion shaft 7. A transmission cavity is provided inside the housing 1, which is connected to a rotating hole and a vibration groove. The two ends of the extrusion shaft 7 are rotatably mounted on the opposite inner walls of the transmission cavity. A plum blossom extrusion wheel 9 is fixedly installed on the outer periphery of the extrusion shaft 7. The plum blossom extrusion wheel 9 is in contact with the side of the vibrating block 10. The extrusion shaft 7 and the outer periphery of the take-up shaft 4 are both fixedly sleeved with first sprockets 8. A first chain 6 is meshed on both of the first sprockets 8. Through the meshing action of the two first sprockets 8 and the first chain 6, the take-up shaft 4 can rotate to drive the extrusion shaft 7 to rotate, thereby causing the plum blossom extrusion wheel 9 to rotate and continuously extrude extrusion on the vibrating block 10. With the elastic action of the return spring 12, the vibrating block 10 is driven to reciprocate up and down.

[0028] A first limiting rod 5 is fixedly installed on the inner wall of the housing 1. One side of the measuring tape 3 is in contact with the outer wall of the first limiting rod 5. Two second limiting rods 14 are fixedly installed on the inner wall of the housing 1. Both sides of the measuring tape 3 are in contact with the outer walls of the two second limiting rods 14. By setting the first limiting rod 5 and the two second limiting rods 14, the measuring tape 3 can be limited, thereby achieving a better cleaning effect during the cleaning process.

[0029] The cleaning assembly also includes two cleaning shafts 17. The inner walls of the housing 1 are provided with transmission grooves, and the two transmission grooves are connected to the transmission cavity. The two ends of the two cleaning shafts 17 are respectively rotatably mounted on the inner walls of the two transmission grooves. The two cleaning roller brushes 19 are respectively fixedly sleeved on the outer walls of the two cleaning shafts 17. With the arrangement of the two cleaning shafts 17 and the two cleaning roller brushes 19, the surface of the tape measure 3 can be cleaned by the two cleaning roller brushes 19 during the winding process.

[0030] A large sprocket 15 is fixedly sleeved on the outer periphery of the take-up shaft 4, and a small sprocket 18 is fixedly sleeved on the outer periphery of one of the cleaning shafts 17. A second chain 16 is meshed on both the large sprocket 15 and the small sprocket 18. Through the meshing action of the large sprocket 15 and the small sprocket 18, the take-up shaft 4 can drive the cleaning shaft 17 to rotate when it rotates.

[0031] Both cleaning shafts 17 are fixedly fitted with linkage gears 20 on their outer periphery. The two linkage gears 20 are meshed and installed. Through the meshing of the two linkage gears 20, when one cleaning shaft 17 rotates, the other cleaning shaft 17 will rotate in the opposite direction, thereby causing the two cleaning roller brushes 19 to rotate synchronously in the opposite direction, resulting in a better cleaning effect.

[0032] The working principle and usage process of this utility model are as follows: When the measuring tape 3 is finished and needs to be wound up, the operating lever 2 is rotated to drive the winding shaft 4 to rotate, thereby winding up the measuring tape 3. During the winding process, the rotation of the winding shaft 4 drives the first sprocket 8 to rotate, which in turn drives the other first sprocket 8, the extrusion shaft 7, and the plum blossom extrusion wheel 9 to rotate under the meshing action of the first chain 6. The plum blossom extrusion wheel 9 continuously extrudes the vibrating block 10, and under the elastic action of the return spring 12, the vibrating block 10 vibrates back and forth continuously. When the two vibrating blocks 10 vibrate back and forth, they can drive the two smoothing plates 13 to move synchronously, shaking the measuring tape 3 during winding and preventing it from folding. Moreover, the pointed ends of the two smoothing plates 13 can smooth the measuring tape 3 passing through the two smoothing plates 13, effectively avoiding the folding phenomenon that is easy to occur when winding too fast, and the winding effect is better.

[0033] Meanwhile, when the winding shaft 4 rotates, it can drive one of the cleaning shafts 17 to rotate under the meshing action of the large sprocket 15, the small sprocket 18, and the second chain 16. Under the meshing action of the two linkage gears 20, the other cleaning shaft 17 rotates synchronously in the opposite direction, thereby driving the two cleaning roller brushes 19 to rotate synchronously in the opposite direction. During the winding process of the tape measure belt 3, it cleans the surface of the tape measure belt 3 of dirt, dust and other foreign objects, and avoids corrosion of the surface of the tape measure belt 3 after winding.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
