Description

Technical Field

[0001] This utility model relates to the field of measuring tools, and in particular to a frame-type measuring tape. Background Technology

[0002] In the field of engineering surveying, frame-type tape measures (also known as frame-type fiber tape measures) are a long-distance measuring tool widely used in construction, land surveying, and urban planning. The tape is mostly made of fiberglass, which has both good flexibility and durability. Combined with the frame structure, which includes a hand-cranked winding mechanism, a handle, and an insert fulcrum, it can achieve efficient measurement of 50 meters, 100 meters, or even longer ranges, meeting the measurement needs of linear dimensions at the hundred-meter level.

[0003] In the design of existing frame-type fiber tape measures, ground positioning is usually achieved by a single insertion fulcrum. This fulcrum is mostly a sharp metal or hard plastic structure, which is directly inserted into the ground such as soil or grass to provide initial fixation. In actual operation, this single-fulcrum structure has gradually revealed its limitations in the following scenarios. First, from the perspective of ground conditions, engineering surveying operations take place in complex and diverse environments, ranging from soft and easily compressible farmland and grassland to sloping terrain and even hard cement or asphalt paved roads. On soft ground, the single fulcrum is prone to settlement due to the compressibility of the ground after insertion, causing the tape measure to tilt as a whole. Moreover, a single fulcrum is difficult to balance the tilting force of the terrain, making it very easy for it to tip over. Second, from the perspective of measurement accuracy and efficiency, long-distance measurements require extremely high straightness of the tape measure. The instability of the single fulcrum structure will cause the tape measure to deviate from the ideal straight trajectory during the pulling process, resulting in significant measurement errors. At the same time, in order to maintain the straightness of the tape measure, operators often need to spend extra effort adjusting the position of the tape measure, which not only reduces measurement efficiency but also increases the workload. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a frame-type measuring tape. Through optimized structural design, it achieves stable support at multiple points, improving measurement accuracy and ease of operation, while also ensuring reliable storage.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A frame-type measuring tape includes a main body housing, on which a rotatable handle for retracting and extending the measuring tape and a positioning tip for inserting into the soil are provided. The main body housing is provided with a removable support member and a connecting member that cooperates with the support member. The support member and the main body housing are detachably connected through the connecting member to form a multi-point support structure.

[0006] Preferably, the connector includes a connecting block, and the connecting block is provided with a positioning support block. The connecting block and the positioning support block are integrally formed, which can enhance the structural strength of the connector and provide a reliable foundation for the stable connection between the support and the main shell.

[0007] Preferably, the positioning block is provided with a limiting surface, and the support member includes a bracket rod. The bracket rod is provided with a positioning groove that cooperates with the positioning block. The fit between the limiting surface and the positioning groove can restrict the relative rotation of the two, ensuring that the main body shell is stably pressed on the bracket rod, thereby improving the stability of the multi-point support.

[0008] Preferably, a storage groove is provided on one side of the support rod, and a rotatable and unfoldable spike assembly is provided in the storage groove. The storage groove can realize the compact storage of the spike assembly, and the rotatable and unfoldable design can quickly form an auxiliary support.

[0009] Preferably, the spike rod assembly includes a spike rod, one end of which has a tapered tip, and the other end is rotatably connected to the support rod. The tapered tip facilitates penetration into various types of soil, and the rotatable connection structure allows the spike rod to flexibly switch between retracted and extended states, making operation simple and efficient.

[0010] Preferably, the spike is provided with a snap-fit ​​rod, and the end of the support rod away from the connecting end is provided with a deformation groove. The deformation groove is provided with a snap-fit ​​end, and the snap-fit ​​end is provided with a snap-fit ​​groove two that engages with the snap-fit ​​rod. The deformation groove provides sufficient deformation space for the snap-fit ​​end, and the engagement of the snap-fit ​​rod and the snap-fit ​​groove two can stably fix the spike after it is unfolded, preventing it from loosening during use.

[0011] Preferably, the support rod is provided with a through hole corresponding to the stud in the storage groove. The position of the through hole corresponds precisely to the stud in the storage state, making it easy for a finger to insert and push the stud out, greatly improving the ease of operation.

[0012] Preferably, the main body shell is provided with a snap-fit ​​block, and the snap-fit ​​block is provided with a deformable deformation end. The deformation end is made of elastic material and can be flexibly deformed under external force, providing structural protection for the quick snap-fit ​​and disassembly of the support.

[0013] Preferably, the support rod is provided with a snap-fit ​​groove near the connecting end. The deformable end can snap into the snap-fit ​​groove to realize the storage and fixation of the support. The snap-fit ​​cooperation between the deformable end and the snap-fit ​​groove can stably fix the support on the main body shell. The storage state is compact and not loose, which is convenient for carrying and transportation.

[0014] Compared with the prior art, the present invention has the following beneficial effects: This utility model features a detachable support component on the main shell, eliminating the need for additional auxiliary support tools during engineering surveys. The support component and positioning tip can be instantly disassembled and assembled to form a multi-point structure, meeting the stable measurement requirements of complex terrains such as soft ground and slopes. This avoids the problems of tilting and shifting of traditional single-point supports and deviation of the measuring tape from the straight line. Furthermore, the support component, through the positioning groove of the connector and the cooperation of the support block, and the elastic design of the deformation end of the locking block, combined with the rotation and unfolding of the spike and the through-hole pushing structure, allows for quick positioning, disassembly, and unfolding of the spike without additional tools, significantly shortening the measurement preparation time and making it more suitable for engineering surveying scenarios such as building construction and land surveying.

They are only for the purpose of simplifying the description of this utility model and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0021] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number. Example

[0022] Please see Figure 1-8 A frame-type measuring tape includes a main body shell 1, with a tape storage cavity inside the main body shell 1, in which the tape can be wound and stored. The main body shell 1 is provided with a rotatable handle 5 for opening and closing the measuring tape and a positioning tip 4 that can be inserted into the soil. The handle 5 is connected to the tape reel via a rotating shaft. Rotating the handle 5 can open and close the tape. The structure of the handle 5 and the positioning tip 4 are consistent with the prior art and will not be described in detail here.

[0023] The outer side wall of the main body shell 1 is integrally formed with a snap-fit ​​block 11. The snap-fit ​​block 11 is provided with a deformable deformable end 111. The deformable end 111 is made of ABS plastic with good elastic deformation ability, and its end is provided with a guide surface to facilitate snap-fit ​​engagement.

[0024] The connector 3 includes a connecting block 31, which is integrally formed on the main body shell 1. The connecting block 31 is provided with a positioning support block 32, and the positioning support block 32 is provided with a limiting surface 33.

[0025] The support member 2 includes a support rod 21, which is flared outward from narrow to wide and is made of the same engineering plastic as the main body shell 1. The narrow end is the connecting end, and the flared end is the supporting end. A positioning groove 22 is provided on the end face of the connecting end of the support rod 21. The shape of the positioning groove 22 is adapted to the positioning block 32. The positioning groove 22 has a flat surface that fits and engages with the limiting surface 33, thus restricting the relative rotation between the main body shell 1 and the support rod 21.

[0026] A snap-fit ​​groove 212 is provided on the support rod 21 near the connection end. The groove shape of the snap-fit ​​groove 212 is adapted to the deformable end 111 of the snap-fit ​​block 11. When the support member 2 is in the storage state, the deformable end 111 deforms under the pressure of external force and snaps into the snap-fit ​​groove 212. After the external force is removed, the deformable end 111 returns to its original shape and fits tightly against the groove wall of the snap-fit ​​groove 212, so as to achieve stable storage of the support member 2 on the main body shell 1.

[0027] A storage groove 211 is provided on one side of the support rod 21 along its length. The width of the storage groove 211 is adapted to the diameter of the spike rod 231, and the depth of the groove is greater than the diameter of the spike rod 231, so as to ensure that the spike rod 231 can be completely stored in the groove. A rotatable spike rod assembly 23 is provided in the storage groove 211. The spike rod assembly 23 includes the spike rod 231. One end of the spike rod 231 is a tapered tip, and the other end of the spike rod 231 is rotatably connected to the support rod 21 through a rotating shaft.

[0028] A snap-fit ​​rod 232 is provided perpendicularly to the spike rod 231. The snap-fit ​​rod 232 is integrally formed with the spike rod 231. A deformation groove 24 is provided at the end of the support rod 21 away from the connecting end. A snap-fit ​​end 25 is provided in the deformation groove 24. The snap-fit ​​end 25 has a certain elastic deformation capability, which facilitates the snap-fit ​​rod 232 to be snapped in and out. A second snap-fit ​​groove 26 is provided on the snap-fit ​​end 25. The second snap-fit ​​groove 26 is an arc-shaped groove. Its shape can fit tightly with the snap-fit ​​rod 232 to ensure the stability of the snap-fit ​​fit.

[0029] The support rod 21 has a through hole 27, which extends through the support rod 21 along its thickness direction and is located in the middle area of ​​the storage groove 211. The diameter of the through hole 27 is large enough for an adult's finger to insert. When the spike rod 231 needs to be unfolded, the finger is inserted through the through hole 27 and pushed to rotate the spike rod 231 around the pivot, so that the spike rod 231 can be rotated out of the storage groove 211.

[0030] The support rod 21 has a mounting end face near the storage slot 211, and a magnetic component 28 is embedded in the mounting end face. The magnetic component 28 is a neodymium iron boron permanent magnet. The main body shell 1 may be provided with a metal material corresponding to the magnetic component 28 when the support member 2 is stored. When the support member 2 is stored on the main body shell 1, it can be stably stored on the main body shell 1 by the attraction of the magnetic component 28.

[0031] When needed, pull the support 2 away from the main body shell 1 to separate the first snap-fit ​​groove 212 on the support 2 from the snap-fit ​​block 11, thereby removing the support 2 from the main body shell 1. Then, insert your finger into the storage groove 211 through the through hole 27 and push the spike 231 to rotate around the pivot, causing the spike 231 to rotate out of the storage groove 211. Then, manually rotate the snap-fit ​​rod 232 on the spike 231 until it aligns with the second snap-fit ​​groove 26 of the snap-fit ​​end 25. At this time, the snap-fit ​​end 25 is pressed by the snap-fit ​​rod 232. A slight deformation occurs, and the snap rod 232 snaps into the snap groove 26, thus unfolding and fixing the spike 231. The positioning groove 22 of the connecting end of the support member 2 is aligned with the positioning block 32 of the connector 3, so that the positioning groove 22 and the positioning block 32 cooperate together, and the limiting surface 33 of the positioning block 32 fits against the plane in the positioning groove 22. Then, the main body shell 1 is pressed down, so that the positioning tip 4 is inserted into the ground, and at the same time, the conical tip of the spike 231 is inserted into the ground, forming a multi-point support structure, and the measurement operation can begin.

[0032] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
