Description

Technical Field

[0001] This utility model relates to the field of measuring devices, specifically a foldable portable measuring device. Background Technology

[0002] In engineering surveying, construction, and daily measurement fields, foldable measuring devices are widely used due to portability requirements. Traditional foldable measuring devices typically achieve folding through hinges or snap fasteners, but these methods suffer from the following technical drawbacks in practical use: First, the folding operation is cumbersome. Existing devices often rely on manually disassembling multiple sets of snap fasteners or aligning hinges, requiring users to repeatedly adjust component positions, which is time-consuming and prone to wear or breakage due to misoperation. For example, some folding measuring rods require unlocking snap fasteners layer by layer and manually bending hinges, resulting in low operational efficiency. Second, the support structure and folding mechanism are mutually restrictive. The support legs or fixed brackets of traditional devices are usually independent structures, requiring additional disassembly and storage during folding, increasing operational complexity. For instance, the folding measuring ruler disclosed in patent (CN202021234567.8) requires its support legs to be disassembled and bound separately, separating them from the main ruler folding process, further reducing portability.

[0003] Therefore, there is an urgent need to optimize the folding structure and support design to realize a convenient foldable portable measuring device, so as to solve the problems of cumbersome folding operation and large storage volume in the existing technology. Utility Model Content

[0004] The purpose of this invention is to provide a foldable portable measuring device that solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a foldable portable measuring device, comprising a measuring device body, wherein a supporting device is connected to the lower end of the measuring device body, the supporting device comprising a folding part, a fixing part, and a supporting part, wherein the fixing part is installed at the upper end of the folding part, the measuring device body is installed at the upper end of the fixing part, the supporting part is installed at the lower end of the fixing part and disposed inside the folding part, wherein a base is connected to the lower end of the supporting part, and the lower end of the folding part is connected to the base.

[0006] As a further optimization of this technical solution, a handle is connected to the upper end of the measuring device body, and the measuring device body is connected to the upper end of the fixed part through a turntable.

[0007] As a further optimization of this technical solution, the fixing part includes a first mounting groove provided near its side, the first mounting groove is provided with threads, the upper end of the first mounting groove is connected to a first sleeve, and the inner and outer sides of the first sleeve are provided with threads, and a rotating handle is also connected to one side of the first sleeve.

[0008] As a further optimization of this technical solution, the folding part includes a connecting part connected to its upper end. The upper end of the connecting part is threaded and screwed into the first sleeve.

[0011] Compared with existing technologies, the foldable portable measuring device of this invention offers the following advantages: Convenient and efficient folding operation: The detachable design with threaded connection (fixed part - first sleeve - folding part) allows for easy separation of the fixed part and folding part simply by rotating the handle. The corrugated folding sleeve automatically retracts due to its own weight, eliminating the need for manual alignment or step-by-step operation, significantly simplifying the folding process; Combining support stability with adjustment flexibility: The support part adopts a linkage structure of "electric telescopic rod + manual telescopic sleeve rod."

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0017] Please see Figures 1 to 3 This embodiment provides a technical solution: a foldable portable measuring device, including a measuring device body 2, a support device connected to the lower end of the measuring device body 2, the support device including a folding part 1, a fixing part 3 and a support part 6, the fixing part 3 is installed at the upper end of the folding part 1, the measuring device body 2 is installed at the upper end of the fixing part 3, the support part 6 is installed at the lower end of the fixing part 3 and is disposed inside the folding part 1, the lower end of the support part 6 is connected to a base 4, and the lower end of the folding part 1 is connected to the base 4.

[0018] More specifically, the measurement is performed by the measuring device body 2, with the base 4 and support 6 providing stable support. The fixing part 3 not only fixes the support 6 and the folding part 1 but also serves as a support platform for the measuring device body 2. The folding part 1 is foldable, making the measuring device easy to fold and carry. The fixing part 3 is used to install and remove the folding part 1. The support 6 adjusts the height and also provides support. When the height is lowered, it works with the folding part 1 to complete the folding adjustment, making the device easy to carry and store.

[0019] In practice, the upper end of the measuring device body 2 is connected to a handle 21, and the measuring device body 2 is connected to the upper end of the fixing part 3 through a turntable 22.

[0020] More specifically, the handle 21 makes it easy to fold and carry, and the turntable 22 makes it easy to rotate the measuring device body 2 for measurement.

[0021] In specific implementation, the fixing part 3 includes a first mounting groove 31 provided near its side, the first mounting groove 31 is provided with threads, the upper end of the first mounting groove 31 is connected to a first sleeve 32, and the inner and outer sides of the first sleeve 32 are provided with threads, and a rotating handle 33 is also connected to one side of the first sleeve 32.

[0022] More specifically, when disassembly is required, the handle 33 can be rotated by hand to rotate and separate the internal thread from the first mounting groove 31, and then pulled upward to complete the disassembly of the first sleeve 32. The disassembly can complete the separation from the lower folding part 1.

[0023] In a specific implementation, the folding part 1 includes a connecting part 11 connected to its upper end. The upper end of the connecting part 11 is threaded and screwed into the first sleeve 32. The lower end of the first sleeve 32 and the upper end of the connecting part 11 are both located in the first mounting groove 31.

[0024] More specifically, by rotating the handle 33, the external thread of the first sleeve 32 can be rotated and separated from the connecting part 11. At this time, the first sleeve 32 is disassembled and separated from the first mounting groove 31, and at the same time, it is separated from the connecting part 11 at the lower end. Pulling it upwards will complete the disassembly. The disassembly can complete the separation from the lower folding part 1. After separation, the folding part 1 folds downwards due to its own weight. The folding part 1 is a corrugated folding sleeve. In this embodiment, the corrugated folding sleeve is sealed. In another embodiment, ventilation holes and ventilation grooves can be provided on the corrugated folding sleeve.

[0025] In specific implementation, the support part 6 includes a telescopic device, and at least three sets of telescopic devices are equidistantly fixed at the lower end of the fixing part 3 and the upper end of the base 4.

[0026] More specifically, the telescopic device includes an electric telescopic rod and manual telescopic sleeves 5. The electric telescopic rod is located in the middle, and the manual telescopic sleeves 5 are located on both sides. The electric telescopic rod extends and retracts to extend the support, while the manual telescopic sleeves 5 on both sides extend and retract passively. The manual telescopic sleeves 5 are equipped with elastic buckles that can automatically lock and fix the device after the maximum extension. The maximum extension is the same as the maximum extension of the electric telescopic rod. This allows for adjustment of the height of the measuring device and adjustment for retraction when carrying, enabling the device to be folded for easy transport.

[0027] In a specific implementation, the base 4 also includes a second mounting groove 41 at its upper end, in which a bearing plate 41 is connected, and the upper end of the bearing plate 41 is fixedly connected to the lower end of the folding part 1.

[0028] More specifically, the bearing plate 41 not only serves to connect the folding part 1 but also allows it to rotate, so that when the folding part 1 is disassembled by the upper fixing part 1, the lower end rotates accordingly. If the folding part 1 does not need to rotate during disassembly, it is only necessary to manually press the folding part 1 to prevent it from rotating with the upper first sleeve 32. Then the connecting part 11 will separate from the first sleeve 32, and then the connecting part 1 and the folding part 1 will fold downwards on their own. This disassembly function is designed to facilitate the maintenance of the support part 6.

[0029] The core components of the electric telescopic pole include: a drive motor: a miniature DC motor (such as a stepper motor or servo motor), which is small in size, has stable torque, and is suitable for the portability requirements of the measuring device; a transmission mechanism: the motor output shaft is connected to a lead screw or gear set, which converts the rotational motion of the motor into the linear extension and retraction motion of the telescopic pole; a control module: a circuit board integrated in the fixing part 3 or the measuring device body 2, which includes a control chip (such as a microcontroller), a signal receiving unit, and a power management module; and a power supply unit: a rechargeable lithium battery (installed in the base 4 or fixing part 3) that powers the motor and control module to meet the needs of outdoor portable use. When the user presses the "raise" button on the measuring device body 2 or fixing part 3, the control module sends a forward rotation command to the drive motor. The motor drives the lead screw to rotate, pushing the telescopic pole body (outer tube) to extend outward along the inner tube until the preset maximum stroke is reached (consistent with the maximum extension of the manual telescopic pole 5). At this time, the manual telescopic pole 5 is passively extended to its limit, and its elastic buckle automatically locks to prevent accidental retraction. When the user presses the "lower" button, the control module sends a reverse rotation command to the motor. The motor drives the lead screw to rotate in the opposite direction, and the telescopic rod body retracts inward. The elastic buckle of the manual telescopic sleeve 5 is released by the pressure and passively retracts synchronously until the telescopic rod is fully reset (shortest state).

[0030] Working principle:

[0031] The working principle of this foldable portable measuring device is based on the synergistic effect of its components. The core lies in the combination of an adjustable support structure, a detachable connection design, and a corrugated folding sleeve to achieve both measurement functionality and convenient folding, as detailed below:

[0032] When the device is in use, the telescopic device of the support part 6 (the electric telescopic rod in the middle and the manual telescopic sleeves on both sides) is in the extended state. The electric telescopic rod extends upward by electric drive, and the manual telescopic sleeves 5 on both sides extend passively in sync with the electric telescopic rod. When the maximum extension is reached, the elastic buckles on the manual telescopic sleeves 5 automatically lock, ensuring that the support part 6 stably supports the fixing part 3 and the measuring equipment body 2. At this time, the device is in a measurable height state.

[0033] The measuring device body 2 is connected to the fixed part 3 via a turntable 22. The user can adjust the direction of the measuring device body 2 by rotating the turntable 22 to meet the measurement needs of different angles. The handle 21 at the upper end of the measuring device body 2 serves as an auxiliary grip structure during measurement, improving operational stability.

[0034] The fixing part 3 is screwed to the internal thread of the first sleeve 32 through the thread in the first mounting groove 31, and the external thread of the first sleeve 32 is matched and screwed to the thread of the upper connecting part 11 of the folding part 1, forming an integrated connection structure of "fixing part 3-first sleeve 32-folding part 1" to ensure the overall stability of the device during measurement.

[0035] When folding is required, hold the handle 33 and rotate the first sleeve 32. The external thread of the first sleeve 32 separates from the thread of the connecting part 11, and at the same time, the internal thread of the first sleeve 32 separates from the thread of the first mounting groove 31 of the fixing part 3. Finally, pull the first sleeve 32 upward from the fixing part 3 to complete the disassembly and separation of the fixing part 3 and the folding part 1.

[0036] Since the folding part 1 is a corrugated folding sleeve, after it is separated from the fixing part 3, its own weight will drive the corrugated structure to naturally shrink and fold downward, forming a compact storage shape. The bearing plate in the second mounting groove 41 at the upper end of the base 4 allows the lower end of the folding part 1 to rotate freely during disassembly (if it is necessary to fix the folding part 1 to prevent it from rotating, the folding part 1 can be manually pressed to restrict its rotation), ensuring a smooth disassembly process.

[0037] The electric telescopic rod of the support part 6 retracts synchronously to its shortest state, and the elastic buckles of the manual telescopic sleeves 5 on both sides are unlocked. As the electric telescopic rod retracts passively, the height of the device is further reduced. In conjunction with the retraction of the folding part 1, the overall volume of the device is significantly reduced (it is easier to carry by hand handle 21 after folding).

[0038] The working principle solves the technical problem of "convenient folding operation" through the following design: the fixed part 3 and the folding part 1 can be separated by rotating the handle 33, avoiding the cumbersome steps of manually aligning multiple parts required by traditional folding devices; the self-weight-driven natural retraction requires no additional power or complicated operation; the linkage design of the electric telescopic rod and the manual telescopic sleeve rod ensures the height stability during measurement and improves storage efficiency by assisting folding through synchronous retraction.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
