Description

Technical Field

[0001] This utility model relates to the field of hanging structure technology, and in particular to a weight hook. Background Technology

[0002] In modern weighing equipment applications, the weight hook is an important component that connects the weights to the weighing equipment, and its design directly affects the accuracy and durability of the weighing equipment.

[0003] Currently, most weight hooks on the market have a typical structure: one end serves as a vertical connection to attach the weight, while the other end is designed as a semi-circular hook to hang the weight. However, this structure has revealed some problems in actual use, as follows:

[0004] First, the surface of the hook end is relatively smooth, which makes the weights prone to swinging when they are hung up. That is, the weights fail to stop immediately on the hook, which not only affects the accuracy of weighing, but also increases the operation time and reduces work efficiency.

[0005] Secondly, the current weight hooks lack an effective fixing structure (to ensure easy replacement). Although the weights are hung by the hooks, if the weights are accidentally dropped during hanging or operation, they will be worn and damaged. Such damage will directly affect the accuracy and reliability of the weights, and further affect the overall accuracy of the weighing equipment.

[0006] Therefore, based on the above problems, we propose a weight hook. Utility Model Content

[0007] The purpose of this invention is to address the shortcomings of existing technologies. It is particularly important to propose a hook structure that provides fast and stable suspension and prevents the weights from falling, so as to avoid damage to the weights due to falling.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A weight hook includes a semi-circular hook end and a weight connecting end integrally formed. The inner arc surface of the semi-circular hook end is provided with a locking groove in the center. Both ends of the locking groove are provided with telescopic grooves. Springs are installed in the telescopic grooves. The corresponding ends of the springs extending into the locking grooves are provided with locking parts. The two locking parts are engaged and abutting each other when the springs are in the free state.

[0010] Furthermore, the snap-fit ​​groove is connected to the telescopic groove, and the cross-section of the snap-fit ​​groove and the telescopic groove are circular, following the arc of the semi-circular hook end.

[0011] Furthermore, one end of the spring is fixed in the telescopic groove, and the other end is fixed to the snap-fit ​​component.

[0012] Furthermore, half of the snap-fit ​​component is located within the snap-fit ​​groove.

[0013] Furthermore, the two snap-fit ​​components are provided with a magnetic structure, a sponge pad, and an arc-shaped component from top to bottom.

[0014] Furthermore, the magnetic attraction structure consists of a recess and a protrusion respectively fixed on two snap-fit ​​components, with the recess and protrusion being matched and engaged.

[0015] Furthermore, the sponge pad is bonded to the corresponding end of the snap-fit ​​component and is located near the upper end of the snap-fit ​​groove.

[0016] Furthermore, the arc-shaped component has a circular arc structure at the end away from the sponge pad, and an inclined structure at the end near the sponge pad.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. A snap-fit ​​groove is centrally located on the inner arc surface of the semi-circular hook end. Expansion slots are provided at both ends of the snap-fit ​​groove, and spring components are installed thereon. The spring components extend into the snap-fit ​​groove and are fitted with snap-fit ​​components. When hanging a weight, the hook enters the snap-fit ​​groove, and the snap-fit ​​components fit against the hook under the action of the spring components, which can quickly suspend the weight, prevent the weight from swinging, and improve weighing accuracy and work efficiency.

[0019] 2. The hook is effectively secured using snap-fit ​​connectors, and the design facilitates the removal of the weights (weight hooks). Specifically:

[0020] Magnetic attraction structure: The two snap-fit ​​parts are equipped with corresponding magnetic attraction structures, which consist of concave and convex seats. They are matched and connected to each other to enhance the contact stability of the snap-fit ​​parts, so that the arc-shaped parts lock the hook and reduce the risk of the weights falling.

[0021] Sponge pad: The corresponding end of the snap fastener is bonded with a sponge pad, which is close to the upper end of the snap fastener groove. When the hook fastener is snapped into the snap fastener groove, it plays a buffering role, reduces the shaking between the hook fastener and the snap fastener, and further improves the suspension speed of the weight.

[0022] Arc-shaped component: The arc-shaped component has a rounded structure at the end away from the sponge pad and an inclined structure at the end closer to the sponge pad. This special structure locks the hook and prevents the hook from detaching from the weight hook. When the hook comes into contact with the rounded and inclined structures, the spring is compressed and opens, allowing the hook to detach from the weight hook. Attached Figure Description

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0037] Example 1

[0038] like Figure 1-4 As shown, this utility model provides a technical solution: a weight hook, comprising a semi-circular hook end 1 and a weight connecting end 2 integrally formed into a weight hook;

[0039] The inner arc surface of the semi-circular hook end 1 is provided with a locking groove 3 in the center, which provides space for the initial positioning of the hook buckle.

[0040] Among them, the hook is a component used to hang weights and weight hooks, and can be ring-shaped or hook-shaped, etc.

[0041] The two ends of the snap-fit ​​groove 3 are provided with telescopic grooves 4, which provide space for the installation of spring components 5, allowing the spring components 5 to extend and retract freely within them. Spring components 5 are installed in the telescopic grooves 4. The spring components 5 have a certain elasticity and can deform when subjected to external force and return to their original shape after the external force is removed. The corresponding ends of the spring components 5 extending into the snap-fit ​​groove 3 are provided with snap-fit ​​components 6. When the spring components 5 are in a free state, the two snap-fit ​​components 6 are in contact with each other. This contacting state allows the snap-fit ​​components 6 to clamp the hook when the hook is inserted into the snap-fit ​​groove 3, through the elastic action of the spring components 5, thereby achieving stable suspension of the weight.

[0042] Example 2

[0043] like Figure 1-4 As shown, the snap-fit ​​groove 3 is connected to the telescopic groove 4. This connection design ensures that the telescopic movement of the spring 5 in the telescopic groove 4 can be smoothly transmitted to the snap-fit ​​6, so that the snap-fit ​​6 can move effectively in the snap-fit ​​groove 3. The cross-sections of the snap-fit ​​groove 3 and the telescopic groove 4 are circular and follow the arc of the semi-circular hook end 1. This design makes the overall structure of the snap-fit ​​groove 3 and the telescopic groove 4 fit better with the semi-circular hook end 1.

[0044] One end of the spring 5 is fixed in the telescopic groove 4, ensuring the stability of the spring 5 in the telescopic groove 4, and the other end is fixed to the snap-fit ​​6, so that the elastic force of the spring 5 can directly act on the snap-fit ​​6, driving the snap-fit ​​6 to move.

[0045] Half of the snap-fit ​​component 6 is located inside the snap-fit ​​groove 3, ensuring that a sufficient portion of the snap-fit ​​component 6 is in the snap-fit ​​groove 3 to hold the hook, while the other portion is built into the semi-circular hook end 1.

[0046] The two snap-fit ​​pieces 6 are provided with a magnetic suction structure 61, a sponge pad 62 and an arc-shaped piece 63 from top to bottom respectively;

[0047] The magnetic structure 61 consists of a recess 611 and a protrusion 612 respectively fixed on two snap-fit ​​parts 6. The recess 611 and the protrusion 612 are matched and engaged. When the hook is put into the snap-fit ​​groove 3, the magnetic structure 61 can further enhance the fixing effect of the snap-fit ​​part 6 on the hook through the magnetic force, preventing the weight hook from shaking or falling off during the suspension process.

[0048] The sponge pad 62 is bonded to the corresponding end of the snap fastener 6 and is close to the upper end of the snap fastener groove 3. The sponge pad 62 has a certain elasticity. When the snap fastener 6 contacts the hook, the sponge pad 62 can play a buffering role, reduce the rigid collision between the hook and the snap fastener 6, and reduce the shaking of the weight hook.

[0049] The arc-shaped part 63 has a rounded structure at the end away from the sponge pad 62, and an inclined structure at the end of the arc-shaped part 63 near the sponge pad 62. The rounded and inclined structures can guide the hook into and out of the snap-fit ​​groove 3, making it easier for the hook into the snap-fit ​​position.

[0050] In the workflow of this utility model, when using a weight hook, the operator holds the weight connecting end 2, aligns the semi-circular hook-shaped end 1 with the hook fastener to which the weight needs to be suspended, and then slowly inserts the hook fastener into the locking groove 3 of the semi-circular hook-shaped end 1. During the process of the hook fastener entering the locking groove 3, it first contacts the arc-shaped component 63. The arc structure of the arc-shaped component 63 guides the hook fastener, allowing it to smoothly enter the locking groove 3. As the hook fastener continues to be inserted, it squeezes the two locking components 6, causing them to move towards the telescopic groove 4. At this time, the spring component 5 is compressed. When the hook fastener is fully inserted into the locking groove 3, the spring component 5, under its own elastic force, pushes the locking components 6 towards the center of the locking groove 3. The weight is moved until the two snap-fit ​​pieces 6 are in contact with the hook, and at the same time, the concave seat 611 and convex seat 612 of the magnetic attraction structure 61 are matched and engaged. The magnetic force further strengthens the fixation of the hook. At this time, the sponge pad 62 is located at the upper end of the contact part between the snap-fit ​​piece 6 and the hook, which plays a buffering and protective role, avoiding rigid contact between the hook and the snap-fit ​​piece 6. In this way, the weight is stably suspended on the weight hook through the hook, which can quickly stop and avoid swinging, thus improving the accuracy of weighing and work efficiency. When it is necessary to remove the weight, the operator only needs to gently pull the weight outward, so that the hook drives the snap-fit ​​piece 6 to overcome the elastic force of the spring piece 5 and move towards the telescopic groove 4, so that the hook can be removed from the snap-fit ​​groove 3.

[0051] 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.
