Description

[0034] In this embodiment, refer to Figure 1 and Figure 2, the first bracket 1 includes a first clamping rod 11, the second bracket 2 includes a second clamping rod 21, the first clamping rod 11 and the second clamping rod 21 are arranged in parallel at intervals, and the first clamping rod 11 and the second clamping rod 21 extend on the same horizontal plane; the upper ends of the first bracket 1 and the second bracket 2 are jointly configured with a hanging area suitable for contacting the neck of the weight; the weight is hung and supported by the first clamping rod 11 and the second clamping rod 21, avoiding direct contact between the operator's hand and the weight, so as to avoid interfering with the weighing accuracy of the weight. In the specific operation process, the user can insert the first clamping rod 11 and the second clamping rod 21 to clamp the neck of the weight, and the space between the first clamping rod 11 and the second clamping rod 21 can accommodate the neck of the weight.
[0035] In this embodiment, refer to Figure 1 and Figure 2 , the first bracket 1 further includes a first limiting portion 14, the first limiting portion 14 is fixedly connected to the end of the first clamping rod 11, the second bracket 2 further includes a second limiting portion 24, and the second limiting portion 24 is fixedly connected to the end of the second clamping rod 21.
[0036] In a specific implementation manner, the first limiting portion 14 and the second limiting portion 24 are respectively bent obliquely upward to limit the outer peripheral side wall surface of the head end of the weight when hanging the weight.
[0037] In another implementation manner, the first limiting portion 14 and the second limiting portion 24 are respectively warped upward to limit the outer peripheral side wall surface of the head end of the weight when hanging the weight.
[0038] The weight clamp provided in this embodiment limits the outer periphery of the head end of the weight through the first limiting portion 14 and the second limiting portion 24, which can prevent the risk of dropping when the operator takes the weight, and prevent personal injury, weight damage and damage to the clean area floor environment.
[0039] As a preferred implementation manner, refer to Figure 1 , the weight clamp further includes a handle 3, the handle 3 is fixedly connected to the first bracket 1 and the second bracket 2 respectively, and the handle 3 is arranged at intervals above the first clamping rod 11 and the second clamping rod 21 to reasonably configure the height space of the hanging area of the weight and the operation space when the operator holds the handle 3.
[0040] As a preferred implementation manner, the first bracket 1, the second bracket 2 and the handle 3 are integrally formed. Of course, the handle 3 can be welded to fix the first bracket 1 and the second bracket 2.
[0041] In a specific implementation, the handle 3 can be provided with grooves that fit the fingers for force application and grasping, so that the user's hand can fit the handle 3 more closely during use, preventing the hand from sliding during use, which is beneficial to improving the use safety.
[0042] As a further implementation manner, refer to Figure 1 and Figure 2 , the first bracket 1 further includes a first adapter rod 12, the first adapter rod 12 is fixedly connected to the end of the first clamping rod 11 away from the first limiting portion 14, the second bracket 2 further includes a second adapter rod 22, and the second adapter rod 22 is fixedly connected to the end of the second clamping rod 21 away from the second limiting portion 24; the first adapter rod 12 and the second adapter rod 22 are arranged in parallel at intervals; any one of the adapter rods is bent upward, and any one of the adapter rods is adapted to limit the outer peripheral side wall surface of the head end of the weight. Specifically, the first adapter rod 12 is bent upward deviating from the first clamping rod 11, and the second adapter rod deviates from the second clamping rod 21 and is bent upward. The outer peripheral side wall surface of the head end of the weight is jointly constrained by the first limiting portion 14, the second limiting portion 24, the first adapter rod 12 and the second adapter rod 22, effectively preventing the risk of the weight loaded on the weight clamp from falling off.
[0043] Preferably, the extending direction of the first adapter rod 12 is perpendicular to the extending direction of the first adapter rod 12, and the extending direction of the second adapter rod 22 is perpendicular to the extending direction of the second adapter rod 22. The overall structure is simple, and with this setting, the weight clamp can be placed on the placement platform through the plane area formed by the first adapter rod 12 and the second adapter rod 22.
[0044] As a further implementation manner, refer to Figure 1 and Figure 2 , the first bracket 1 further includes a first connecting rod 13, one end of the first connecting rod 13 is fixedly connected to the end of the first adapter rod 12 away from the first clamping rod 11, the other end of the first connecting rod 13 is fixedly connected to the handle member 3, the second bracket 2 further includes a second connecting rod 23, one end of the second connecting rod 23 is fixedly connected to the end of the second adapter rod 22 away from the second clamping rod 21, and the other end of the second connecting rod 23 is fixedly connected to the handle member 3; the first connecting rod 13 and the second connecting rod 23 are arranged in parallel at intervals.
[0045] As a preferred implementation manner, the first connecting rod 13 and the first clamping rod 11 are arranged in the same direction and away from the first adapter rod 12; the second connecting rod 23 and the second clamping rod 21 are arranged in the same direction and away from the second adapter rod 22. With this setting, the overall center of gravity of the weight clamp can be advanced towards the hanging area, improving the stability of the overall structure of the weight clamp.
[0046] As a further embodiment, the extended length of the first connecting rod 13 is less than that of the first clamping rod 11; the extended length of the second connecting rod 23 is less than that of the second clamping rod 21, so that the handle 3 connected by the first connecting rod 13 and the second connecting rod 23 can be located at the upper end of the hanging area, facilitating the hand force application of the operator when clamping the weights. It can reasonably establish the center of gravity position of the weight clamp, avoid the failure of weight picking and placing or the falling off of the weights, and cause personal injury; at the same time, the weight clamp can be stably placed on the placement platform through the plane area formed by the first clamping rod 11 and the second clamping rod 21.
[0047] The weight clamp provided in this embodiment has a fixed overall structure. Different sizes of weight clamps can be designed according to different specifications. The weight clamp does not need to be adjusted, and the operation is simple, efficient, stable and safe. When in use, it will not cause damage or falling off of the weights due to abnormal situations such as the unadjusted adjustment part or the loosening of the adjustment part. The weight clamp can easily clamp the neck of the weight when clamping the weight, and it is not easy to fall off after being clamped. For weights of different specifications, the weight clamp selects corresponding different sizes, and reasonably configures the distance between the first bracket 1 and the second bracket 2, the extended lengths of the first clamping rod 11 and the second clamping rod 21, and the height distance between the handle 3 and the plane formed by the first clamping rod 11 and the second clamping rod 21; the weight clamp can actually be used to clamp two specifications of weights, one is a 5 Kg weight and the other is a 10 Kg weight.
[0048] The weight clamp provided in this embodiment, see Figure 1 and Figure 2 , the shapes of the first bracket 1 and the second bracket 2 in the weight clamp are set to U-shaped, and the front ends of their clamping rods are set to upwardly curved arcs. The arcs closely adhere to the weights during clamping, making the clamping more secure and preventing the weights from slipping when clamping the weights.
[0049] As a preferred embodiment, see Figure 1 , the weight clamp further includes one or more connecting members 4. The connecting members 4 are fixedly connected between the first bracket 1 and the second bracket 2, and the connecting members 4 are arranged to avoid the hanging area. Connecting members 4 are arranged between the first bracket 1 and the second bracket 2 for reinforcement, improving the structural strength and stability of the weight clamp, facilitating the more stable picking and placing of the weight clamp for weights, and the weight clamp is not easily deformed during long-term use and has a longer service life.
[0050] In a specific embodiment, see Figures 1 to 4, the connecting member 4 is arranged as a crossbar structure. One end of the crossbar structure is fixedly connected to the first bracket 1, and the other end of the crossbar structure is fixedly connected to the second bracket 2. The projection line of the crossbar structure on the horizontal plane is perpendicular to the projection line of the first clamping rod 11 on the horizontal plane. The crossbar structure can be arranged as a hollow rod, which is beneficial to reducing the structural weight. The overall structure of the weight clamp is simple, and the structural strength and stability are good.
[0051] In some embodiments, the first bracket 1, the second bracket 2, the handle member 3, and the connecting member 4 in the weight clamp can be made of SUS304 stainless steel and integrally welded. The welding position can be polished, and it is easy to clean without dead corners.
[0052] As a preferred embodiment, see Figure 4 , the weight clamp further includes damping sleeves 5. There are two damping sleeves 5 respectively. One damping sleeve 5 is sleeved on the first clamping rod 11, and the other damping sleeve 5 is sleeved on the second clamping rod 21. The damping sleeve 5 can be specifically arranged as a silica gel sleeve. On the one hand, when the weight clamp picks up and places the weight, the damping sleeve 5 can provide a flexible protection effect on the weight, preventing the weight from being damaged during clamping and affecting the calibration result. On the other hand, after the weight is clamped, the damping sleeve 5 plays a damping role on the weight, increasing the friction between the weight and the weight clamp, and can avoid the displacement and falling off of the weight. Of course, the entire weight clamp can be provided with damping sleeves 5. For example, on the handle member 3, it can prevent the risk of the operator's hand slipping during operation.
[0053] The weight clamp provided by the present utility model has the following usage method:
[0054] The operator holds the handle member 3 of the weight clamp and slowly moves the weight clamp to align the first limiting portion 14 and the second limiting portion 24 in the weight clamp with the neck of the weight. Move the weight clamp to hang the neck of the weight on the upper ends of the first clamping rod 11 and the second clamping rod 21. After confirming that the clamping is in place, then gently lift the weight to perform daily calibration on the stirring system and the platform scale. After the calibration is completed, hold the handle of the weight clamp again and slowly move the weight clamp to align the clamping part of the weight clamp with the neck of the weight. Confirm that the clamping is in place, then gently lift the weight and put it into the weight protection box to complete the operation of the weight and meet the requirements of daily use.
[0055] The weight clamp provided by this embodiment can ensure the accuracy of weight weighing, avoid interfering with the weighing of products, and improve the safety and convenience in the stage of picking up and placing the weight.
[0056] Obviously, the above embodiments are merely examples given for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of this utility model creation.
