Description

Technical Field

[0001] This utility model relates to the field of portable scales, specifically a wirelessly connected printing portable scale. Background Technology

[0002] The wireless-connected printing handheld scale is a portable electronic device that integrates weighing, wireless communication, and label printing functions. This device can not only accurately measure the weight of items, but also has built-in wireless modules such as Bluetooth, which can connect to the cloud system to achieve real-time synchronization of product information. After weighing, it can automatically drive the printing device to print.

[0003] Traditional wireless-connected portable scales still require manual lifting when weighing heavy objects. The operator must hold the scale with one or both hands for an extended period of time and bear the full weight of the object being weighed. Since it is difficult for the human body to remain completely still for a long time when lifting heavy objects, even slight shaking or posture adjustments can cause the scale to vibrate, disrupting the force balance of the weighing sensor and thus affecting the accuracy and stability of the weighing results. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, traditional wireless-connected printing handheld scales still require manual lifting when weighing heavy objects. The operator must hold the scale with one or both hands for an extended period of time and bear the full weight of the object being weighed. Since it is difficult for the human body to remain completely still for a long time when lifting heavy objects, even slight shaking or posture adjustments can cause the scale to vibrate, disrupting the force balance of the weighing sensor and thus affecting the accuracy and stability of the weighing results. This utility model proposes a wireless-connected printing handheld scale.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a wireless connection printing handheld scale, including a handheld scale body, and a suspension mechanism is provided on one side of the handheld scale body;

[0006] The suspension mechanism includes a U-shaped block disposed on one side of the handheld scale body. A first mounting block is fixedly connected to one end of the U-shaped block, and a second mounting block is fixedly connected to one side of the handheld scale body. One side of the first mounting block contacts one side of the second mounting block. A rotating column is rotatably connected to the inner wall of the first mounting block, and a locking block is fixedly connected to one end of the rotating column. An installation groove is formed on the inner wall of the second mounting block, and the inner wall of the installation groove contacts the surfaces of the rotating column and the locking block. A locking slot is connected to the inner wall of the installation groove, and the surface of the locking block contacts the inner wall of the locking slot.

[0007] Preferably, a fixing block is fixedly connected to one side of the hand-held scale body, and a rotating shaft is rotatably connected to the inner wall of the fixing block. Both ends of the rotating shaft are fixedly connected to the inner wall of the U-shaped block, and the U-shaped block is rotatably connected to the hand-held scale body through the rotating shaft.

[0008] Preferably, the inner wall of the U-shaped block is fixedly connected with an anti-slip pad, which is made of rubber.

[0009] Preferably, a limiting groove is formed on the inner wall of the first mounting block, and a torsion spring is sleeved on the surface of the rotating column. One end of the torsion spring is fixedly connected to the surface of the rotating column, and the other end of the torsion spring is fixedly connected to the inner wall of the limiting groove.

[0010] Preferably, the inner wall of the first mounting block is provided with a semi-annular groove, and a positioning block is fixedly connected to the surface of the rotating column, with the surface of the positioning block in contact with the inner wall of the semi-annular groove.

[0011] Preferably, the bottom of the handheld scale body is provided with anti-collision blocks, and the number of anti-collision blocks is two. A damper is fixedly connected between the bottom of the handheld scale body and the side opposite to the anti-collision blocks.

[0012] The advantages of this utility model are:

[0013] This invention features a suspension mechanism that uses a U-shaped block to suspend the handheld scale body on the horizontal bar of a shelf. Rotating the rotating column causes the locking block to enter the locking slot, forming an anti-detachment structure. This prevents the U-shaped block from falling off due to accidental factors, thus avoiding damage to the equipment caused by the handheld scale body falling. The weighing process does not require manual lifting of the handheld scale body; simply placing the item on the hook completes the weighing and printing. This reduces the impact of human shaking on the weighing accuracy and ensures the accuracy and stability of the measurement data. Attached Figure Description

[0020] 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 scope of protection of the present utility model.

[0021] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0022] This application discloses a wirelessly connected printing portable scale. (Refer to...) Figure 1 , Figure 2 and Figure 3 A wirelessly connected printing portable scale includes a portable scale body 1, and a suspension mechanism 2 is provided on one side of the portable scale body 1.

[0023] The suspension mechanism 2 includes a U-shaped block 201, which is disposed on one side of the handheld scale body 1. A first mounting block 202 is fixedly connected to one end of the U-shaped block 201, and a second mounting block 203 is fixedly connected to one side of the handheld scale body 1. One side of the first mounting block 202 contacts one side of the second mounting block 203. A rotating column 204 is rotatably connected to the inner wall of the first mounting block 202, and a locking block 205 is fixedly connected to one end of the rotating column 204. An installation groove 206 is formed on the inner wall of the second mounting block 203, and the inner wall of the installation groove 206 contacts the surfaces of the rotating column 204 and the locking block 205. The inner wall of the scale is connected to a slot 207. The surface of the block 205 contacts the inner wall of the slot 207. By setting a suspension mechanism 2, the hand-held scale body 1 is suspended on the crossbar of the shelf by the U-shaped block 201. Then, the rotating column 204 is rotated to make the block 205 enter the slot 207, forming an anti-detachment structure to prevent the U-shaped block 201 from falling off due to accidental factors, thus avoiding damage to the equipment caused by the hand-held scale body 1 falling. The weighing process does not require manual lifting of the hand-held scale body 1. The item can be weighed and printed simply by placing it on the hook. This reduces the impact of human shaking on the weighing accuracy and ensures the accuracy and stability of the measurement data.

[0024] Reference Figure 2A fixed block 4 is fixedly connected to one side of the hand-held scale body 1. A rotating shaft 5 is rotatably connected to the inner wall of the fixed block 4. Both ends of the rotating shaft 5 are fixedly connected to the inner wall of the U-shaped block 201. The U-shaped block 201 is rotatably connected to the hand-held scale body 1 through the rotating shaft 5. With the setting of the fixed block 4 and the rotating shaft 5, the U-shaped block 201 can be rotatably connected to the back of the hand-held scale body 1, so that the U-shaped block 201 can rotate and unfold or retract around the rotating shaft 5, realizing the attachment and detachment from the shelf crossbar.

[0025] Reference Figure 2 The inner wall of the U-shaped block 201 is fixedly connected with an anti-slip pad 6, which is made of rubber. The anti-slip pad 6 increases the friction between the U-shaped block 201 and the shelf crossbar, preventing the hand scale body 1 from sliding or shifting during the weighing process.

[0026] Reference Figure 3 The inner wall of the first mounting block 202 is provided with a limiting groove 7, and a torsion spring 9 is sleeved on the surface of the rotating column 204. One end of the torsion spring 9 is fixedly connected to the surface of the rotating column 204, and the other end of the torsion spring 9 is fixedly connected to the inner wall of the limiting groove 7. By setting the torsion spring 9, the rotating rod can be provided with a torsional elastic restoring force, so that the rotating column 204 can automatically return to the initial position after rotation.

[0027] Reference Figure 3 The inner wall of the first mounting block 202 is provided with a semi-annular groove 8. The surface of the rotating column 204 is fixedly connected with a positioning block 10. The surface of the positioning block 10 is in contact with the inner wall of the semi-annular groove 8. Through the setting of the semi-annular groove 8 and the positioning block 10, the rotating column 204 can be guided and limited during rotation. The semi-annular groove 8 is 180 degrees. The starting end and the ending end of the semi-annular groove 8 correspond to the locking position and the unlocking position, respectively, so that the card block 205 can be accurately and completely disengaged from the card slot 207.

[0028] Reference Figure 4 The bottom of the portable scale body 1 is provided with anti-collision blocks 3, and there are two anti-collision blocks 3. A damper 11 is fixedly connected between the bottom of the portable scale body 1 and the side opposite to the anti-collision blocks 3. The anti-collision blocks 3 and the damper 11 can protect the bottom of the portable scale body 1. The damper 11 is composed of elastic pads and shock-absorbing columns, which can absorb and disperse the impact force when falling, reducing damage to internal parts.

[0029] Working principle: The wirelessly connected portable scale uses an internal weighing sensor to sense the pressure of the object, generating deformation and outputting an electrical signal. The microprocessor then quickly calculates and processes the signal, ultimately displaying the weight on the scale's screen. After weighing, the scale wirelessly transmits the weight data to a paired printer via a built-in Bluetooth module. Finally, the receiving device prints the label. This is existing technology and will not be elaborated further. When weighing heavy objects, the user first manually unfolds the U-shaped block 201 on the back of the portable scale body 1 by rotating the pivot 5. Then, the U-shaped block 201 is hung on the surface of the shelf crossbar. Rotating the U-shaped block 201 closes it. Simultaneously, the user manually rotates the rotating column 204 inside the first mounting block 202. The rotating column 204 drives the locking block 205 to rotate synchronously. As the rotating column 204 rotates, it causes the torsion spring 9 to twist. The torsion spring 9 stores torsional potential energy. Meanwhile, during the rotation of the rotating column 204, the positioning block 10 on the surface moves within the semi-annular groove 8, which is 180 degrees. The starting end of the semi-annular groove 8 corresponds to the locking position, and the ending end corresponds to the unlocking position. When the rotating column 204 drives the fixing block 4 to the end position of the semi-annular groove 8, the position of the locking block 205 aligns with the position of the mounting groove 206 of the second mounting block 203. As the U-shaped block 201 closes, the rotating column 204 and the locking block 205 enter the mounting groove 206. At this time, the user releases the rotating column 204, and the rotating column 204 will drive the locking block 205 to rotate under the torsional force of the torsion spring 9. After rotation, the locking block 205 will enter the locking groove 207 connected to the mounting groove 206, thereby locking the U-shaped block 201. After that, the user hangs the heavy object on the hook of the hand scale body 1 for weighing.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
