Description

Technical Field

[0001] The utility model relates to the field of weighing weights, in particular to a portable weight. Background Art

[0002] Portable weights generally refer to measuring instruments that are easy to carry, simple to operate, and have appropriate accuracy. They play an important role in various occasions that require accurate weighing.

[0003] In the prior art, some devices usually use sponges for fixation during use. The sponge will compress when subjected to pressure, and this characteristic will cause slight changes in the position of the weight during the fixation process. Especially in the case of long-term placement or repeated use, the elasticity of the sponge will cause the instability of the weight position during the loading and unloading of the weight, increasing the risk of the weight colliding and rubbing against the device. For this reason, a portable weight is proposed to solve the above problems. Summary of the Utility Model

[0004] In order to make up for the above deficiencies, the utility model provides a portable weight, aiming to improve the problem that it is difficult to clamp and fix in the prior art. The lack of firm fixation will cause the weight to slide or collide during transportation or storage, thus damaging the surface of the weight.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A portable weight, comprising a box body. The front side of the top of the box body is rotatably connected with a top cover. A fixing block is fixedly connected to the inner wall of the top cover. A weighing device is slidably connected to the inner wall of the box body. A gripper is slidably connected to the inner wall of the box body. A support block is fixedly connected to the inner wall of the box body. Two round rods are slidably connected to the inner wall of the support block. Limit blocks are respectively fixedly connected to the outer walls of the two opposite sides of the two round rods. A tension spring is sleeved on the outer wall of the round rod. Hard rubber clamping blocks are respectively fixedly connected to the outer walls of the two adjacent sides of the two tension springs. A quick-release component is fixedly connected to the inner wall of the box body, and the quick-release component is used for quickly opening the box body. The box body is designed for long-term use, can withstand repeated loading and unloading and transportation processes, reducing the cost and environmental impact of single use.

[0007] As a further description of the above technical solution:

[0008] The quick-release component includes an insertion block. A square bayonet is provided on the inner wall of the insertion block. A telescopic block is slidably connected to the inner wall of the box body. A first spring is sleeved on the outer wall of the telescopic block. A rotating block is rotatably connected to the inner wall of the box body. A second spring is fixedly connected to the inner wall of the box body. A pushing block is slidably connected to the rear inner wall of the box body. A sliding block is slidably connected to the inner wall of the pushing block. The second spring can undergo elastic deformation when subjected to an external force and quickly return to its original state after the external force is removed, which makes the second spring suitable for applications that require a stable force or vibration damping.

[0009] As a further description of the above technical solution:

[0010] The inner wall of the fixed block is in contact with the outer wall of the weighing device. The outer wall of the limiting block is in contact with the outer wall of the supporting block. The supporting block can increase the stability of the mechanical structure and prevent deformation or collapse caused by external forces or uneven internal stresses.

[0011] As a further description of the above technical solution:

[0012] The outer wall of the tension spring is fixedly connected to the outer wall of the hard rubber block. The outer wall of the tension spring is fixedly connected to the inner wall of the supporting block. The tension spring can achieve precise control of force through the actions of stretching and rebounding, and is suitable for scenarios that require fine force control.

[0013] As a further description of the above technical solution:

[0014] The outer wall of the hard rubber block is slidably connected to the outer wall of the weighing device. An insertion block is fixedly connected to the inner wall of the top cover. Although hard rubber is hard, it still retains the elasticity of rubber and can provide buffering when compressed or vibrated, reducing the impact force.

[0015] As a further description of the above technical solution:

[0016] The outer wall of the insertion block is slidably connected to the inner wall of the box body. The inner wall of the insertion block is engaged with the outer wall of the rotating block. The box body can effectively protect the items loaded inside from external factors, such as humidity, dust, and collision.

[0017] As a further description of the above technical solution:

[0018] The outer wall of the rotating block is engaged with the inner wall of the square bayonet. The top of the gripper is in contact with the bottom of the fixed block. Using the gripper to pick up the weights can prevent contaminants such as sweat, grease, or dust on the hands from staining the weights, thus maintaining the cleanliness and accuracy of the weights.

[0019] As a further description of the above technical solution:

[0020] The bottom of the sliding block is slidably connected to the top of the rotating block, and the top of the second spring is fixedly connected to the bottom of the rotating block. The rotating block can effectively transfer energy from one axis to another axis, reducing energy loss.

[0021] The utility model has the following beneficial effects:

[0022] 1. In the utility model, the weighing device presses the hard rubber block to drive the round rod, and the tension spring is extruded, so clamping and fixing are realized. A stable fixation can ensure that the weights will not slide or collide during transportation or storage, thereby protecting the surface of the weights. The fixed weights can reduce wear caused by friction or impact, and extend the service life of the weights.

[0023] 2. In the utility model, by pushing the push block to drive the sliding block to press down, the rotating block is disengaged from the insertion block, so the function of quick disassembly is realized. The lid that can be quickly opened is usually designed with anti-slip or buffering functions, and can stably control the opening and closing actions without damaging the weights.

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Refer to Figure 1 and Figure 2 For an embodiment provided by the present utility model: a portable weight, including a box body 1, a top cover 2 is rotatably connected to the front side of the top of the box body 1. The box body 1 serves as the basis of the entire device and is made of a sturdy material to ensure the safety and integrity of the internal weights. Its design is compact, facilitating portability and storage. A fixed block 3 is fixedly connected to the inner wall of the top cover 2. The top cover 2 is installed on the front side of the top of the box body 1 by a rotatable connection method. This design enables the top cover 2 to be easily opened and closed, providing convenience for accessing the weights. A weighing device 4 is slidably connected to the inner wall of the box body 1, and a gripper 5 is slidably connected to the inner wall of the box body 1. A support block 6 is fixedly connected to the inner wall of the box body 1. The support block 6 is used to fix and support the round rod 7 to ensure its stability and positioning during use. Two round rods 7 are slidably connected to the inner wall of the support block 6. Limiting blocks 8 are respectively fixedly connected to the outer walls of the far sides of the two round rods 7. The round rods 7 are connected to the support block 6 by a sliding connection method. The design of the round rods 7 allows them to move smoothly under the guidance of the support block 6, thereby driving the movement of the limiting blocks 8 and the hard rubber clamping blocks 10. A tension spring 9 is sleeved on the outer wall of the round rod 7. Hard rubber clamping blocks 10 are respectively fixedly connected to the outer walls of the near sides of the two tension springs 9. The two ends of the tension spring 9 are respectively connected to the round rod 7 and the hard rubber clamping block 10. When the hard rubber clamping block 10 is subjected to an external force, the tension spring 9 will be stretched, thereby generating a reverse elastic force. A quick-release component is fixedly connected to the inner wall of the box body 1. The quick-release component is used for quickly opening the box body 1.

[0032] Refer to Figure 3 and Figure 4, The quick-release component includes an insertion block 11. A square bayonet 12 is provided on the inner wall of the insertion block 11. The insertion block 11 is a key part of the quick-release component, designed with a shape matching the structure of the box body 1, usually made of metal to ensure that it will not easily deform or be damaged when subjected to external forces. The inner wall of the insertion block 11 is designed with a square bayonet 12 for connecting with other components of the box body 1 to form a stable and tight locking structure. A telescopic block 13 is slidably connected to the inner wall of the box body 1. A first spring 14 is sleeved on the outer wall of the telescopic block 13. The design enables the telescopic block 13 to perform telescopic movement under the action of the first spring 14. The square end of the telescopic block 13 can match the square bayonet 12 of the insertion block 11 to achieve the functions of locking and unlocking through telescopic movement. A rotating block 15 is rotatably connected to the inner wall of the box body 1. A second spring 16 is fixedly connected to the inner wall of the box body 1. A pushing block 17 is slidably connected to the rear inner wall of the box body 1. The function of the pushing block 17 is to push the sliding block 18 in through external operation, thereby indirectly affecting the movement of the telescopic block 13 to achieve the unlocking of the quick-release component. The design of the pushing block 17 takes into account the convenience and safety of operation to ensure that users will not be accidentally injured during use. A sliding block 18 is slidably connected to the inner wall of the pushing block 17.

[0033] Refer to Figure 1 , Figure 3 , Figure 4, the inner wall of the fixed block 3 is in contact with the outer wall of the weighing device 4. This design ensures the stable position of the weighing device 4 within the box body 1, preventing displacement due to vibration during transportation or operation, which could affect the measurement accuracy. The fixed block 3 is designed with a rubber layer to reduce the impact of friction and vibration on the weighing device 4. The outer wall of the limit block 8 is in contact with the outer wall of the support block 6. The design of the limit block 8 ensures the position limitation of the round rod 7 during the sliding process, preventing structural damage caused by excessive movement. The outer wall of the tension spring 9 is fixedly connected to the outer wall of the hard rubber block 10. This design enables the hard rubber block 10 to quickly return to its original position under the elastic force of the tension spring 9 when subjected to an external force. The use of the tension spring 9 not only enhances the gripping force of the hard rubber block 10 but also ensures its smooth and rapid return to the initial position when released. The outer wall of the tension spring 9 is fixedly connected to the inner wall of the support block 6. The outer wall of the hard rubber block 10 is slidably connected to the outer wall of the weighing device 4. The inner wall of the top cover 2 is fixedly connected with an insertion block 11. The outer wall of the insertion block 11 is slidably connected to the inner wall of the box body 1. The inner wall of the insertion block 11 is engaged with the outer wall of the rotating block 15. This design controls the connection and separation of the insertion block 11 and the box body 1 through the rotational movement of the rotating block 15, realizing the unlocking of the quick-release component. The engagement point between the insertion block 11 and the rotating block 15 is designed with a groove to ensure that it will not be accidentally unlocked due to external forces in the locked state. The outer wall of the rotating block 15 is engaged with the inner wall of the square bayonet 12. The bottom of the sliding block 18 is slidably connected to the top of the rotating block 15. This design enables the sliding block 18 to move smoothly driven by the rotating block 15, indirectly controlling the movement of the telescopic block 13 to realize the unlocking of the quick-release component. The top of the second spring 16 is fixedly connected to the bottom of the rotating block 15.

[0034] Working principle: When the weighing device 4 is placed into the box body 1, the weighing device 4 will press the hard rubber block 10. Under the pressure of the weighing device 4, the hard rubber block 10 will push the round rod 7 to slide on the inner wall of the support block 6, and the hard rubber block 10 will also compress the tension spring 9. When the weighing device 4 completely falls into the box body 1, the hard rubber block 10 will generate a thrust under the action of the tension spring 9 to engage with the weighing device 4. When it is necessary to take it out, use the gripper 5 to grip the top of the weighing device 4, and the weighing device 4 will push the hard rubber block 10 to contract the tension spring 9. Thus, clamping and fixing are realized. A stable fixation can ensure that the weights will not slide or collide during transportation or storage, thereby protecting the surface of the weights. The fixed weights can reduce wear caused by friction or impact and extend the service life of the weights.

[0035] When it is necessary to quickly open the box body 1, push the push block 17. The push block 17 will push the sliding block 18, causing the sliding block 18 to press down. The sliding block 18 presses the rotating block 15 to contract the second spring 16 and then causes the rotating block 15 to rotate. The rotation of the rotating block 15 causes the rotating block 15 to disengage from the insertion block 11 to complete the quick opening. For quick closing, cover the top cover 2. The insertion block 11 presses the telescopic block 13 to contract the first spring 14, and the insertion block 11 engages with the rotating block 15 to complete the quick closing and locking. Therefore, the function of quick disassembly is realized. The quickly opened lid is usually designed with anti-slip or buffering functions, which can stably control the opening and closing actions without damaging the weights.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
