Description

Technical Field

[0001] This utility model application relates to the field of portable weighing instrument technology, specifically to a portable weighing instrument that is easy to move. Background Technology

[0002] Weighing instruments are measuring devices used to measure the mass of objects. Their history can be traced back to the ancient balance scale, and in modern times they have evolved into precision instruments that integrate sensor technology, microelectronics, and digital technology. As a key tool for trade settlement, industrial production, and scientific research experiments, weighing instruments achieve weighing through principles such as lever principle, elastic deformation, or electromagnetic force balance. According to their structure, they can be divided into two main categories: mechanical weighing instruments (such as spring scales) and electronic weighing instruments (such as electronic balances). According to their uses, they cover commercial platform scales, industrial rail scales, laboratory analytical balances, and special vehicle weighing systems, etc.

[0003] Chinese Patent Publication No. CN218724677U discloses a portable weighing instrument, relating to the field of electronic scale equipment technology. It includes: a weighing mechanism, a protective mechanism at the top of the weighing mechanism, a moving mechanism on one side of the weighing mechanism, and an indication mechanism inside the weighing mechanism. The installed weighing mechanism allows for better internal storage of the device, integrating the weighing instrument into a single unit for easier carrying. Furthermore, the cooperation between the installed wheels and the moving mechanism enables the device to be pulled and moved, facilitating its movement and user convenience. The protective mechanism protects the internal weighing instrument and tray when not in use. The interaction between the indication mechanism and the protective shell effectively conceals the wireless indicator.

[0004] In the aforementioned patent document, the weighing instrument weighs items by placing the items on the weighing mechanism. However, when the items are heavy, the weighing mechanism is prone to overloading, which can easily damage it. Therefore, a portable weighing instrument that is easy to move is proposed. Utility Model Content

[0005] To address the aforementioned problems, a portable weighing instrument that is easy to move is provided. When the electronic scale weighs a heavy item, the weight of the item acts on the scale, causing it to press down through the first limiting groove and the adapter block. This causes the support rod to move downwards along the central axis of the limiting hole until the support foot fixed at the bottom of the support rod contacts the ground. This allows the support mechanism to support the electronic scale, thereby improving its load-bearing capacity. It also solves the problem of electronic scales being easily damaged by overload.

[0006] To address the problems of the prior art, this application provides a portable weighing instrument that is easy to move, including a mobile trolley, a pushing mechanism disposed on one side of the mobile trolley, an electronic scale disposed on the top of the mobile trolley for weighing items, a support mechanism disposed inside the mobile trolley for supporting the electronic scale, an energy storage battery disposed inside the mobile trolley, and a limiting mechanism disposed inside the mobile trolley for clamping the energy storage battery. The lower end surface of the electronic scale is provided with a plurality of first limiting grooves at equal intervals.

[0007] The bottom of the mobile trolley is longitudinally provided with limiting holes that correspond one-to-one with the first limiting groove;

[0008] The support mechanism includes a support rod that is longitudinally installed in the limiting hole and can move along the central axis of the limiting hole. The top end of the support rod is fixed with an adapter block that can be adapted to the first limiting groove. The bottom end of the support rod extends downward out of the interior of the moving trolley. The bottom end of the support rod is fixed with a support foot. A first return spring is installed on the outside of the support rod. The first return spring is located at the bottom of the adapter block.

[0009] As one technical solution of this application, the limiting mechanism includes a bidirectional threaded rod horizontally installed on both sides inside the mobile trolley, and a worm gear is fixed at one end of the bidirectional threaded rod.

[0010] The limiting mechanism also includes a bidirectional worm shaft horizontally installed inside the moving trolley. The central axis of the bidirectional worm shaft intersects perpendicularly with the central axis of the bidirectional threaded rod on the projection plane, and both ends of the bidirectional worm shaft can mesh with the worm wheel.

[0011] A handwheel for driving its rotation is fixed on the bidirectional worm shaft.

[0012] As one technical solution of this application, the mobile trolley is provided with symmetrical sliding rails on both sides inside;

[0013] The limiting mechanism also includes a clamping rod mounted on a bidirectional threaded rod, with grooves at both ends of the clamping rod that can slide and engage with the slide rail.

[0014] As one technical solution of this application, the clamping rod has a threaded hole on the side wall near the slide groove that can be threaded with the bidirectional threaded rod.

[0015] As a technical solution of this application, the side wall of the clamping rod near the threaded hole is provided with a second limiting groove, and a sliding rod is fixed inside the second limiting groove. A clamping block for limiting the two ends of the energy storage battery is slidably installed on the sliding rod.

[0016] A second reset spring is fitted onto the slide bar to drive the clamping block to reset.

[0017] As one technical solution of this application, the pushing mechanism includes a fixed frame fixed to the outer wall of the mobile trolley, a clearance groove is longitudinally provided on the fixed frame, a gripping rod is installed in the clearance groove, and nuts for fixing the gripping rod are installed at both ends of the gripping rod. The nuts are fitted onto the ends of the gripping rod and are threaded together.

[0018] The advantages of this utility model application compared to the prior art are:

[0019] When the electronic scale weighs a heavy item, the weight of the item acts on the scale, causing it to press down through the first limiting groove and the adapter block. This causes the support rod to move downwards along the central axis of the limiting hole until the support foot fixed at the bottom of the support rod contacts the ground. This allows the support mechanism to support the electronic scale, thereby improving its load-bearing capacity. It also solves the problem of electronic scales being easily damaged by overload.

[0028] To further understand the features, technical means, and specific objectives and functions achieved by this utility model application, the following detailed description of this utility model application is provided in conjunction with the accompanying drawings and specific embodiments.

[0029] See Figures 1-7 As shown, a portable weighing instrument that is easy to move includes a mobile trolley 1, a pushing mechanism 2 disposed on one side of the mobile trolley 1, an electronic scale 3 disposed on the top of the mobile trolley 1 for weighing items, a support mechanism 4 disposed inside the mobile trolley 1 for supporting the electronic scale 3, an energy storage battery 5 disposed inside the mobile trolley 1, and a limiting mechanism 6 disposed inside the mobile trolley 1 for clamping the energy storage battery 5. The lower end surface of the electronic scale 3 is provided with a plurality of first limiting grooves 31 at equal intervals.

[0030] The bottom of the mobile trolley 1 is longitudinally provided with limiting holes 12 that correspond one-to-one with the first limiting groove 31;

[0031] The support mechanism 4 includes a support rod 41 that is longitudinally installed in the limiting hole 12 and can move along the central axis of the limiting hole 12. The top end of the support rod 41 is fixed with an adapter block 43 that can be adapted to the first limiting groove 31. The bottom end of the support rod 41 extends downward out of the interior of the moving trolley 1. The bottom end of the support rod 41 is fixed with a support foot 42. A first return spring 44 is installed on the outside of the support rod 41. The first return spring 44 is located at the bottom of the adapter block 43.

[0032] When the electronic scale 3 weighs a heavier item, the weight of the item acts on the electronic scale 3, causing it to press down through the first limiting groove 31 and the adapter block 43. This causes the support rod 41 to move downwards along the central axis of the limiting hole 12 until the support foot 42 fixed at the bottom of the support rod 41 contacts the ground. This allows the support mechanism 4 to support the electronic scale 3, thereby improving its load-bearing capacity and solving the problem of the electronic scale 3 being easily damaged by overload.

[0033] See Figure 3 , Figure 4, Figure 5 and Figure 6 As shown, the limiting mechanism 6 includes a bidirectional threaded rod 61 horizontally installed on both sides inside the moving trolley 1, and a worm gear 611 is fixed at one end of the bidirectional threaded rod 61.

[0034] The limiting mechanism 6 also includes a bidirectional worm shaft 63 horizontally installed inside the moving trolley 1. The central axis of the bidirectional worm shaft 63 intersects perpendicularly with the central axis of the bidirectional threaded rod 61 on the projection plane. Both ends of the bidirectional worm shaft 63 can mesh with the worm wheel 611.

[0035] A handwheel 631 for driving its rotation is fixed on the bidirectional worm shaft 63.

[0036] When the handwheel 631 is turned, it drives the bidirectional worm shaft 63 to rotate. Simultaneously, the rotation of the bidirectional worm shaft 63 drives the bidirectional threaded rod 61 to rotate synchronously through the worm wheel 611 meshing with it. This achieves the rotation of the two bidirectional threaded rods 61 in clockwise and counterclockwise directions, respectively.

[0037] See Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, slide rails 11 are symmetrically arranged on both sides inside the mobile trolley 1;

[0038] The limiting mechanism 6 also includes a clamping rod 62 mounted on the bidirectional threaded rod 61. The clamping rod 62 has grooves 621 at both ends that can slide and cooperate with the slide rail 11.

[0039] To ensure the stability of the clamping rod 62 during movement, grooves 621 are provided at both ends of the clamping rod 62. When the clamping rod 62 moves, it can move along the central axis of the slide rail 11 through the grooves 621, thus ensuring the stability of the clamping rod 62.

[0040] See Figure 5 and Figure 6 As shown, the clamping rod 62 has a threaded hole 622 on its side wall near the slide groove 621, which can be threadedly engaged with the bidirectional threaded rod 61.

[0041] To ensure that the bidirectional threaded rod 61 can effectively drive the clamping rod 62 to move, a threaded hole 622 is provided on the side of the clamping rod 62 near the slide groove 621. The threaded hole 622 is threadedly engaged with the bidirectional threaded rod 61. When the bidirectional threaded rod 61 rotates, it can drive the clamping rod 62 to move through the threaded hole 622, thereby enabling the clamping rod 62 to clamp or release the energy storage battery 5.

[0042] See Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the clamping rod 62 has a second limiting groove 623 on the side wall near the threaded hole 622. A slide rod 624 is fixed inside the second limiting groove 623. A clamping block 626 for limiting the two ends of the energy storage battery 5 is slidably installed on the slide rod 624.

[0043] A second return spring 625 is mounted on the slide bar 624 for resetting the clamping block 626.

[0044] By fixing the slide rod 624 within the second limiting groove 623, and then sliding the clamping block 626 onto the slide rod 624, the clamping block 626 can limit the two ends of the energy storage battery 5, effectively preventing displacement of the energy storage battery 5. During the process of limiting the energy storage battery 5, the clamping block 626 will compress the second return spring 625 on the slide rod 624, causing the second return spring 625 to gradually accumulate potential energy. When the clamping block 626 detaches and contacts the energy storage battery 5, the potential energy accumulated by the second return spring 625 is released, thereby causing the second return spring 625 to push the clamping block 626 back to its initial position.

[0045] See Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the pushing mechanism 2 includes a fixed frame 21 fixed on the outer wall of the mobile trolley 1. A clearance groove 22 is longitudinally provided on the fixed frame 21. A gripping rod 23 is installed in the clearance groove 22. Nuts 24 for fixing the gripping rod 23 are installed at both ends of the gripping rod 23. The nuts 24 are fitted onto the ends of the gripping rod 23 and are threaded together.

[0046] The height of the gripping rod 23 can be adjusted by moving the gripping rod 23 along the relief groove 22. When the gripping rod 23 is adjusted to the appropriate height, the nut 24 is rotated so that one side of the nut 24 can make close contact with the side of the fixing frame 21, and the gripping rod 23 is fixed by the friction between the nut 24 and the fixing frame 21.

[0047] The above embodiments only illustrate one or more implementation methods of this utility model application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model application, and these all fall within the protection scope of this utility model application. Therefore, the protection scope of this utility model application should be determined by the appended claims.
