Description
Technical Field
[0001] The utility model relates to the technical field of lead button clamping, in particular to a special lead button clamp which is safe, efficient and labor-saving. Background Art
[0002] The fire assay method is a classical analytical method that applies metallurgical principles and techniques to analytical chemistry, mainly used for quantitatively determining the content of precious metals in ores and metallurgical products. This method has the advantages of good sampling representativeness, wide method applicability, good enrichment effect, etc., and is an important means for the chemical analysis of gold, silver and precious metals.
[0003] During the fire assay process, after the sample undergoes the melting step, a lead button rich in precious metals will be formed. However, in the traditional fire assay process, there are often some problems in clamping the lead button. In such a high-temperature environment, directly using a short clamp to clamp the lead button poses a serious risk of scalding. Moreover, the traditional clamping method usually requires the operator to repeatedly apply force to clamp the lead button in and out of the high-temperature area, which not only increases the operation time but also reduces the work efficiency. And due to the lack of stability during the clamping process, the tool is likely to cause the lead button to fall or be damaged, thereby affecting the accuracy of the experimental results.
[0004] Regarding the problem that the tool is likely to cause the lead button to fall or be damaged due to lack of stability during the clamping process in the above solution, the closing and opening of the bottom clamping mouth are controlled by the U-shaped handle at the top, and the clamping mouth is controlled by the limit ring not to be misaligned, and the clamping mouth is set at a 45° angle, so as to achieve the effect of accurately, conveniently and stably clamping the lead button and preventing the lead button from falling off. Summary of the Utility Model
[0005] The purpose of the utility model is to solve the deficiencies existing in the prior art, and to propose a special lead button clamp that is safe, efficient and labor-saving, and the technical problem it solves is that the tool is likely to cause the lead button to fall or be damaged due to lack of stability during the clamping process.
[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0007] A special lead button clamp that is safe, efficient and labor-saving, including a rubber pad grip and a firing cup body. There are two rubber pad grips, and the tops of the two rubber pad grips are fixedly connected with a U-shaped series rod. The bottom of the U-shaped series rod is provided with a clamping mouth block, and the bottom of the rubber pad grip is provided with an annular fixing block. The annular fixing block is used to enable the clamping mouth block to easily open when the operator slightly exerts force on the rubber pad grip. Thus, the taking of the lead button can be made more convenient and light, which not only simplifies the operation process but also greatly reduces the physical consumption of the operator, making the work of clamping the lead button and putting it into the ash dish more labor-saving.
[0008] As a further improvement of the present utility model, connecting rods I are fixedly connected to the bottom ends of the rubber pad grips. The bottom ends of the connecting rods I are fixedly connected with abutting positioning blocks. The bottom ends of the abutting positioning blocks are fixedly connected with connecting rods II. One end of the annular fixing block is fixedly connected to the outside of one connecting rod II, and the other end of the annular fixing block is movably connected to the inside of the other connecting rod II. Thus, it plays a role in opening the two clamping blocks and preventing misalignment during the process of the clamping blocks crossing each other.
[0009] As a further improvement of the present utility model, abutting tubes are fixedly connected to the mutually adjacent sides of the connecting rods II. An elastic block is slidably connected to the mutually adjacent sides of the two abutting tubes. Springs are fixedly connected to both sides of the elastic block. The sides of the springs away from the elastic block are fixedly connected to the inside of the abutting tubes close to the elastic block. Thus, it plays a role in controlling the opening and closing angle of the clamping blocks as a fulcrum and has the effect that the clamping blocks can be opened by slightly exerting force on the rubber pad grips during use.
[0010] As a further improvement of the present utility model, threaded grooves are formed in the bottom ends of the connecting rods II. Threaded blocks are threadedly connected to the inside of the threaded grooves. Support rods are fixedly connected to the bottom ends of the threaded blocks. Arc-shaped rods are fixedly connected to the bottom ends of the support rods. Thus, it can be achieved that when the anti-slip grooves are severely worn, they can be replaced conveniently.
[0011] As a further improvement of the present utility model, two clamping blocks are provided. The two clamping blocks are respectively fixedly connected to the bottom ends of the two arc-shaped rods. Anti-slip grooves are symmetrically formed in the mutually adjacent sides of the bottom ends of the clamping blocks. Thus, by setting the bottom ends of the clamping blocks into 45° elbows and forming anti-slip grooves, lead buttons can be better clamped from the lead button tray and it can be ensured that they will not fall off.
[0012] As a further improvement of the present utility model, the anti-slip groove part at the bottom end of the clamping block is made of austempered ductile iron. Thus, the effects of heat resistance and light weight can be achieved.
[0013] As a further improvement of the present utility model, the distance from the top end of the U-shaped series rod to the bottom end of the clamping block is 1.8 meters, wherein the distance from the top end of the U-shaped series rod to the annular fixing block is 1.4 meters, and the distance between the annular fixing block and the bottom end of the clamping block is 0.4 meters. Thus, with sufficient and not redundant length, it can be ensured that the operator will not be scalded by high temperature.
[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0015] 1. Through the rubber pad grip, U-shaped series rod, annular fixing block and connecting rod two, when the operator tightly holds the rubber pad grip, the connecting rod two drives the clamping blocks to move away from each other under the fulcrum action of the contact tube. Thus, when the operator slightly exerts force to hold the rubber pad grip, the clamping blocks can be easily opened, facilitating the clamping of lead buttons. After the clamping is completed, simply release the hand, and the clamping blocks will automatically close under the action of the springs on both sides of the annular fixing block and the elastic block, achieving the effect of clamping lead buttons without the operator continuously exerting force. This design is convenient and lightweight to hold and will not be scalded by high temperature. It not only simplifies the operation process but also greatly reduces the physical consumption of the operator, making the work of clamping lead buttons and putting them into the ash dish more labor-saving.
[0016] 2. Through the rubber pad grip, elastic block, spring and arc rod, when it is necessary to take and flip the firing cup body to pour out, by tightly holding the rubber pad grip, the connecting rod two drives the arc rods to move away from each other under the fulcrum action of the contact tube, causing the arc rods to form an opening, so that the operator can conveniently take out the firing cup body. Thus, this device can achieve the effects of taking the firing cup body and clamping lead buttons simultaneously. In the traditional fire assay process, two or more tools or devices are required to complete these two tasks separately. However, one device can achieve both simultaneously, significantly reducing the time and steps of tool switching, improving work efficiency. Moreover, it reduces the dependence on multiple independent devices, lowers the cost of equipment procurement and maintenance, and since the operation becomes more simple and fast, it may reduce the requirements for the number or skill level of operators, thus indirectly reducing labor costs.

DETAILED DESCRIPTION
[0022] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific implementation disclosed below.
[0023] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.
[0024] As shown in the figure, a safe, efficient and labor-saving lead buckle special clamp includes a connecting rod 101, a rubber pad handle 102, a U-shaped series rod 103, an annular fixing block 105, a connecting rod 2 106, a resistance tube 107, an elastic block 108 and a clamping block 203.
[0025] When the operator needs to transfer the lead buckle, the operator holds the rubber pad handles 102 at both ends tightly, so that due to the series connection of the rubber pad handles 102 at both ends by the U-shaped series rod 103, the rubber pad handles 102 will drive the connecting rod 1 101 to approach each other, and since the rubber pad handles 102 and the middle part of the connecting rod 2 106 are connected in series by the abutment positioning block 104, the connecting rod 2 106 also approaches each other, and the abutment tube 107 fixedly connected in the middle part of the connecting rod 2 106 is abutted by the spring 109 fixedly connected by the elastic block 108, so that the connecting rod 2 106 drives the two support rods 201 to move outward in the opposite direction, and since the support rod 201 and the clamping block 203 are fixedly connected by the arc rod 202, when the operator holds the rubber pad handle 102 with a little force, the clamping blocks 203 can be easily opened, so that the lead buckle can be clamped. Moreover, after the clamping is completed, the operator only needs to release his hands, and the clamping blocks 203 will automatically close due to the action of the springs 109 on both sides of the annular fixing block 105 and the elastic block 108, thereby achieving the effect of clamping the lead buckle without the operator having to exert continuous force.
[0026] Further, when it is necessary to place the firing cup body 300 into the combustion furnace or take out the firing cup body 300 from the combustion furnace, pinch the rubber pad grip 102 in the same steps as above. At this time, the clamping block 203 will be opened. Then, pass the opening through the outside of the narrow mouth of the firing cup body 300, and then release the rubber pad grip 102 to make the clamping block 203 close again. At this time, move the arc rod 202 upward to make the arc rod 202 fit with the firing cup body 300, so that this device can achieve the effects of taking and holding the firing cup body 300 and clamping the lead button at the same time. In the traditional fire assay process, two or more tools or devices are required to complete these two tasks separately. However, one device can achieve both at the same time, significantly reducing the time and steps of tool switching and improving work efficiency.
[0027] Further, after this gripper is used for a long time, the anti-slip effect of the anti-slip groove 204 may become poor due to the long-term friction between the anti-slip groove 204 and the lead button, and the arc rod 202 may be deformed at high temperature due to the long-term contact with the firing cup body 300. Through the threaded connection between the threaded block 205 and the threaded groove 110, the arc rod 202 and the clamping block 203 can be replaced conveniently, so as to achieve the effect of replacing the worn gripper head. The worn gripper head may cause unstable clamping or a decrease in clamping force, thus affecting the speed and efficiency of the production line. Most of the existing devices are integrally designed, and replacing the new gripper head can ensure that the gripper can complete the clamping action stably and quickly, reducing unnecessary damage caused by the lead button falling due to clamping failure, thus improving the overall production efficiency.
[0028] The advantages of the present utility model are as follows: 1) When the operator slightly exerts force to hold the rubber pad grip 102, the clamping blocks 203 can be easily opened, facilitating the clamping of the lead button. 2) This device is convenient and light to take, and will not be scalded by high temperature. It not only simplifies the operation process but also greatly reduces the physical consumption of the operator, making the work of clamping the lead button and putting it into the ash cup more labor-saving. 3) This device can achieve the taking of the firing cup body 300 and the clamping of the lead button at the same time. 4) The worn gripper head can be replaced conveniently. Replacing the new gripper head can ensure that the gripper can complete the clamping action stably and quickly, reducing unnecessary damage caused by the lead button falling due to clamping failure.
[0029] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
