Description

Technical Field

[0001] The utility model relates to the technical field of glove chains, and more specifically to a quick-detachable single-mode glove chain. Background Art

[0002] PVC gloves are made of polyvinyl chloride. They do not contain allergenic materials, are powder-free, have low dust generation, low ion content, do not contain plasticizers, fats, silicones, oils and other ingredients, have strong chemical resistance, good flexibility and touch, are anti-static, and are easy and comfortable to wear. Therefore, they are widely used in health inspections, labor protection in food, chemical, electronics, pharmaceutical and other industries, as well as family health protection. The market demand is also quite large.

[0003] The existing PVC glove production line is a chain driven by a power mechanism in a circle, and a ceramic hand mold fixed by a hand mold seat is installed on each side of the curved plates on both sides of the chain that constitutes the ring chain. The ceramic hand mold is dipped in PVC glue during the transmission process of the chain, and then dried and formed into gloves. The current single-mode glove chain is relatively bulky. During the transmission process, the bulky transmission chain is easy to cause useless work at work, and consumes a lot of energy and wastes resources. Therefore, it is necessary to develop an energy-saving and environmentally friendly single-mode glove chain.

[0004] In response to the above problems, application number 201922347733.3, application name is a single-mode glove chain, which includes a pin and a sleeve sleeved on the middle of the pin, both ends of the sleeve are sleeved with inner link plates, the outer side of the inner link plate is provided with an outer link plate sleeved on the pin, the inner link plate is provided with an ear plate bent outward, the ear plate is provided with a perforation, the weight is reduced on the original technical solution, thereby reducing energy consumption, and at the same time making low carbon and environmental protection issues significantly improved.

[0005] Although the device has many beneficial effects, the following problems still exist: during the long-term use of the single-mode glove chain, the chain connection is often subjected to high-frequency movement and friction during the chain transmission process. This friction will cause wear of the chain connection, thereby affecting the transmission efficiency, stability and life of the chain. Although the device reduces a certain amount of counterweight, the friction wear still exists, which undoubtedly affects the long-term use of the single-mode glove chain;

[0006] Secondly, during the use of the device, it is often necessary to transport gloves of various sizes, so the ceramic hand molds of various sizes need to be frequently replaced. The existing methods mostly use bolts and nuts to fix the ceramic hand mold on the ear plate. This results in the need to use tools to disassemble the bolts and nuts each time the ceramic hand mold is replaced, which not only reduces the replacement efficiency, but also increases the labor intensity of the personnel.

[0007] In view of this, we propose a quick-release single-mode glove chain. Utility Model Content

[0008] 1. Technical problems to be solved

[0009] The utility model aims to provide a quick-release single-mode glove chain to solve the problems of long-term wear of the chain and cumbersome replacement of the glove molds in the above-mentioned background technology.

[0010] 2. Technical solution

[0011] A quick-release single-mode glove chain comprises an outer chain link and an inner chain link. The outer wall of the outer chain link is provided with a limit sleeve and a mounting assembly. The mounting assembly comprises a fixing rod. A connecting shaft is connected between the plurality of inner chain links. The plurality of outer chain links are rotatably connected to the side walls of the inner chain links by means of the connecting shaft.

[0012] Preferably, a rotation groove is provided inside the limiting sleeve, and a ball bearing is movably engaged with the inner wall of the rotation groove.

[0013] Preferably, the end of the fixed rod is rotatably connected to a rotating rod, and the end of the rotating rod is connected to a connecting block.

[0014] Preferably, a limiting plug is provided inside the connection block, a spring is connected between the plurality of limiting plugs, a threaded rod is threadedly connected to the top of the connection block, and the threaded rod is connected to a pressure connecting rod after extending into the connection block.

[0015] Preferably, a second ball is movably engaged with the front and rear outer walls of the connecting shaft, and a threaded pressing nail is threadedly sleeved on the top of the connecting shaft.

[0016] Preferably, a trapezoidal movable block is slidably arranged inside the connecting shaft, and a plurality of side walls of the trapezoidal movable blocks are provided with telescopic columns.

[0017] Preferably, the front outer walls of the plurality of telescopic columns are threadedly connected with threaded pressing convex rods, a second spring is arranged inside the telescopic column, the ends of the second springs are connected with a limiting block, a third ball is movably clamped on the outer wall of the limiting block, and the limiting block matches the rotating groove.

[0018] 3. Beneficial effects

[0019] Compared with the prior art, the utility model has the advantages that: during the use and installation of the chain, the inner chain link carrying the connecting shaft can be installed between multiple outer chain links, and then the threaded pressing nail can be locked by a tool, and the threaded pressing nail can be used to drive the telescopic column to be inserted into the corresponding limit sleeve, and then the threaded pressing protrusion can be locked, and the threaded pressing protrusion can be used to press and lift the limit block so that it can be limited on the inner wall of the rotating groove. Since the rotating groove is provided with ball 1, it can better cooperate with ball 3 on the outer wall of the limit block to reduce the friction loss on the outer side of the outer chain link, and ball 2 arranged on the front and rear side walls of the connecting shaft can reduce the wear on the inner side of the outer chain link, thereby better extending the service life of the entire chain, and when the chain is damaged, it is also more convenient to repair and replace it;

[0020] When it is necessary to replace ceramic hand molds of various sizes, it is only necessary to rotate the threaded rod to drive the pressure connecting rod to rotate, so that the pressure connecting rod can release the pressure limit on the two limit plugs. At this time, due to the action of spring 1, the two limit plugs will move similarly to achieve the retraction of the two limit plugs, thereby better releasing the fixation of the ceramic hand mold. During installation, it is only necessary to rotate the pressure connecting rod in the opposite direction again to drive the two limit plugs to extend and then install the ceramic hand mold to limit the ceramic hand mold, making it more convenient to replace the ceramic hand mold.
