Description

Technical Field

[0001] This utility model relates to the field of balance technology, specifically a portable balance. Background Technology

[0002] As a precision weighing instrument, the balance is widely used in laboratories, shopping malls, and other places. With the development of technology, the functions of balances have become increasingly diverse. For example, Chinese invention patent CN102435278A discloses a "balance with object recognition function," which automatically identifies the type of item to be weighed by setting an object recognition system on the scale body, consisting of an object camera, an information storage device, and an information comparator. This eliminates the need to manually enter barcodes or unit prices, effectively improving weighing efficiency, and is particularly suitable for supermarkets and farmers' markets.

[0003] However, the aforementioned existing technologies and most balances on the market are designed primarily to enhance the functionality and intelligence of the weighing process, while generally neglecting the portability of the product. The scale body of such balances is usually a single piece, and the weighing pan, control panel, and other components lack effective protection during transportation, making them susceptible to damage from bumps and impacts, thus affecting weighing accuracy. At the same time, most balances do not have dedicated, ergonomic handles or grip structures, so when they need to be moved, users can only hold them by hand, which is not only inconvenient to exert force but also poses a risk of slipping. This causes great inconvenience for users who need to frequently move the balance between different workbenches or locations (such as on-site inspectors, teachers, etc.). Utility Model Content

[0004] The purpose of this invention is to provide a portable balance to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a portable balance, comprising a balance body, a platform at the top center of the balance body, multiple sets of support frames movably connected to the top annular surface of the platform, and inclined brackets movably connected between adjacent support frames, with anti-slip blocks vertically fixed to one end of each set of support frames.

[0006] The top of the balance body is covered with a lifting mechanism, which includes a shield, a limiting rod, and a pull ring. Two limiting rods are hinged to the front surfaces of both the balance body and the shield. A pull ring is hinged to the front surface of the shield. Two fixing blocks are fixed to the front surface of the pull ring. A telescopic column runs horizontally through the interior of each fixing block. Locking blocks and discs are fixed to both ends of the telescopic column along its length. A spring is sleeved on the outside of the telescopic column. Two baffles are fixed to the front surface of the balance body.

[0007] As a preferred embodiment of this utility model, a plug is fixedly connected to the disc, and a hole is passed through the inside of the baffle, into which the plug is inserted.

[0008] In a preferred embodiment of this invention, one end of the spring is connected to the fixed block, and the other end of the spring is connected to the disc.

[0009] As a preferred embodiment of this utility model, the two baffles are located on both sides of the pull ring, and the disc abuts against the baffles.

[0010] In a preferred embodiment of this invention, the centers of the telescopic column, the disc, and the insert block are all on the same horizontal line, and the fixing block and the telescopic column are slidably connected.

[0011] As a preferred technical solution of this utility model, the bottom of the shield is provided with a storage groove, and the platform, support frame, bracket and anti-slip block are all located in the storage groove.

[0012] In a preferred embodiment of this utility model, a first pull rod is movably connected between the two limiting rods, and multiple sets of slots are provided at the bottom of the first pull rod. A second pull rod is movably connected between the other two limiting rods, and multiple sets of locking blocks are fixed to the top of the second pull rod. Semi-circular anti-slip grooves are provided on the rear surfaces of both the first and second pull rods. The first and second pull rods are fixed by engaging and locking the locking blocks and slots.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By designing a lifting mechanism that can be closed onto the top of the balance body, the handle function and the protective function are cleverly combined into one. The cover can protect the buttons on the platform and the surface of the balance body from external impact and accidental touch when not in use. Through the spring-driven telescopic column and plug structure, the pull ring can be quickly locked on the baffle and the balance body. At this time, the entire balance body can be easily and stably lifted and carried by holding the hinged pull rod, which fundamentally solves the problems of inconvenient handling and easy slippage of traditional balances.

[0015] 2. An extended frame consisting of multiple sets of movable connecting support frames and brackets is set on the loading platform. When unfolded, this structure can significantly increase the area of ​​the weighing platform, making it convenient to weigh large or irregular items. The anti-slip block ensures the stability of the items. When it is necessary to carry or store them, the entire frame can be quickly folded and stored in the storage slot at the bottom of the cover. The structure is compact and easy to operate, achieving a unity of functionality and portability.

[0016] 3. By setting a first pull rod and a second pull rod that are movably connected to two sets of limit rods respectively, and setting multiple sets of interlocking blocks and slots on both, the modularity and functional integration of the lifting mechanism are realized. When the first pull rod and the second pull rod are interlocked, they combine to form an integrated handle with better length and grip, significantly improving the stability and comfort of carrying, effectively dispersing lifting stress, and avoiding structural fatigue caused by stress concentration. At the same time, semi-circular anti-slip grooves are opened on the rear surface of the first pull rod and the second pull rod. This design is ergonomic and can naturally accommodate the user's fingers, greatly increasing the friction between the hand and the handle, thus providing reliable anti-slip protection during transportation, further reducing the risk of the balance falling and being damaged due to slipping, and enhancing the overall safety of the product.

Detailed Implementation

[0025] 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.

[0026] Example 1

[0027] Please see Figures 1 to 7 This utility model provides a portable balance, including a balance body 1, a platform 11 at the top center of the balance body 1, the balance body 1 and the platform 11 are fixed together by a gravity sensor, the gravity sensor is a QLTSC, multiple sets of support frames 12 are movably connected to the top annular surface of the platform 11, and brackets 13 distributed at an incline are movably connected between adjacent support frames 12, and anti-slip blocks 14 are vertically fixed to one end of the multiple sets of support frames 12.

[0028] The top of the balance body 1 is covered by a lifting mechanism 2. The lifting mechanism 2 includes a cover 21, a limiting rod 22 and a pull ring 23. The front surfaces of the balance body 1 and the cover 21 are both hinged with two limiting rods 22. The front surface of the cover 21 is hinged with a pull ring 23. The front surface of the pull ring 23 is fixed with two fixing blocks 24. The interior of the two fixing blocks 24 is transversely penetrated by a telescopic column 25. The two ends of the telescopic column 25 and along its own length are respectively fixed with a locking block 26 and a disc 27. The outside of the telescopic column 25 is fitted with a spring 28. The front surface of the balance body 1 is fixed with two baffles 29.

[0029] In this embodiment, the above-mentioned structures together constitute the core of the portable balance. The foldable expandable frame, composed of the support frame 12, the bracket 13, and the anti-slip block 14, can be folded up to reduce its volume when not in use; when large objects need to be weighed, it can be quickly unfolded to expand the bearing area. The anti-slip block 14 effectively prevents items from slipping. The lifting mechanism 2, composed of components such as the cover 21, the limiting rod 22, and the pull ring 23, achieves a combination of protection and portability: in the transport state, the lifting mechanism 2 can be firmly locked on the balance body 1, making it easy to carry; in the use state, it can also serve as a protective cover to protect the balance's precise weighing components.

[0030] Example 2

[0031] Please see Figure 4 and Figure 5A plug 271 is fixedly connected to the disc 27. A hole is passed through the inside of the baffle 29. The plug 271 is inserted into the hole. One end of the spring 28 is connected to the fixed block 24, and the other end of the spring 28 is connected to the disc 27. The two baffles 29 are located on both sides of the pull ring 23. The disc 27 and the baffles 29 are in contact. The center of the telescopic column 25, the center of the disc 27 and the center of the plug 271 are all on the same horizontal line. The fixed block 24 and the telescopic column 25 are slidably connected.

[0032] In this embodiment, when it is necessary to fix the lifting mechanism 2, the user pulls the locking block 26 inward to compress the spring 28, causing the insert 271 to exit from the insertion hole of the baffle 29, thus releasing the lock. When the pull ring 23 is moved between the two baffles 29 and aligned, the locking block 26 is released, and the restoring force of the spring 28 will push the telescopic column 25 to move laterally until the insert 271 is accurately inserted into the insertion hole of the baffle 29, thereby achieving a fast and reliable lock. This design ensures that the lifting mechanism 2 is tightly connected to the balance body 1 during transportation and will not accidentally loosen, ensuring safety and reliability. The design of the collinearity of the centers of each component ensures uniform force distribution and smooth operation.

[0033] Example 3

[0034] Please see Figure 1 , Figure 2 and Figure 6 The bottom of the shield 21 is provided with a storage slot, and the platform 11, the support frame 12, the bracket 13 and the anti-slip block 14 are all located in the storage slot.

[0035] In this embodiment, the storage slot design at the bottom of the shield 21 achieves the ultimate utilization of space. When the foldable support frame 12, bracket 13 and anti-slip block 14 are folded up, they can be completely accommodated in this storage slot. This makes the entire balance form a compact and regular whole when not in use, which greatly facilitates storage and transportation, effectively avoids damage to moving parts due to shaking and collision during movement, and further enhances the portability and durability of the product.

[0036] Example 4

[0037] Please see Figure 1 , Figure 3 and Figure 7 The first pull rod 221 is movably connected between the two limiting rods 22. The bottom of the first pull rod 221 has multiple sets of slots 222. The second pull rod 223 is movably connected between the other two limiting rods 22. The top of the second pull rod 223 is fixed with multiple sets of blocks 224. The rear surfaces of the first pull rod 221 and the second pull rod 223 are both provided with semi-circular anti-slip grooves 225. The first pull rod 221 and the second pull rod 223 are engaged and fixed by the blocks 224 and the slots 222.

[0038] In this embodiment, the design of the first pull rod 221 and the second pull rod 223 further optimizes the carrying experience. When the balance body 1 needs to be carried, the user can engage the first pull rod 221 and the second pull rod 223 with the locking block 224 and the locking slot 222 on them, so that the two are combined to form a wider and more stable hand handle. After being combined into one, the contact area of ​​the hand is increased, making the lifting action more effortless and comfortable. At the same time, the semi-circular anti-slip grooves 225 opened on the rear surface of the first pull rod 221 and the second pull rod 223 provide a natural placement position for the user's fingers, effectively increasing friction and significantly reducing the risk of the balance accidentally slipping out of the hand during movement, thus enhancing the safety and reliability of the carrying process.

[0039] Working principle: First, release the lock of the lifting mechanism 2: The user simultaneously presses the locking blocks 26 on both sides inward, causing the telescopic column 25 to move inward against the elastic force of the spring 28, thereby causing the insert block 271 on the disc 27 to exit from the insertion hole of the baffle 29. After the lock is released, the cover 21 can be opened by flipping it upward through the pull ring 23 or the limit rod 22, exposing the weighing components. Next, unfold the weighing platform: The multiple sets of support frames 12 that are gathered in the bottom storage slot of the cover 21 are unfolded outward one by one. The brackets 13 between adjacent support frames 12 are then opened and locked, forming a stable and significantly expanded extended support surface. The anti-slip block 14 on it is used to prevent items from slipping. Then, the item to be weighed is placed on the center of the platform 11 or on the expanded support surface, and the gravity sensor inside the balance body 1 can weigh it. If it needs to be moved... After the balance body 1 is folded and the cover 21 is closed and locked, the first pull rod 221 and the second pull rod 223 can be engaged with the slot 222 via the locking block 224. By holding the integrated pull rod and the anti-slip groove 225, the balance body 1 can be easily and stably lifted and carried. After use, the above reverse process is repeated: first, the support frame 12 and the bracket 13 are folded and retracted so that they are completely stored in the storage slot; then the cover 21 is closed, and the pull ring 23 is aligned and pushed into the position between the two baffles 29. At this time, under the restoring force of the spring 28, the telescopic column 25 will automatically move outward, driving the insertion block 271 to accurately insert into the insertion hole of the baffle 29, completing the automatic locking. Finally, the user can safely and effortlessly carry the entire balance body 1 by using the integrated first pull rod 221 and the second pull rod 223.
