Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of emergency stop switch, specifically relates to a cover plate structure of emergency stop switch. BACKGROUND

[0002] The emergency stop button can also be called an emergency stop button, and is simply called an emergency stop button in the industry, which is self-explanatory. The emergency stop button is used to protect people when an emergency occurs by pressing the button quickly. The emergency stop button can quickly stop or release some transmission parts by directly pressing down. The device must be released to start again. In industrial safety, all machines that can directly or indirectly cause harm to the human body under abnormal conditions must be protected. The emergency stop button is one of them.

[0003] However, when the existing device requires an emergency stop function, an emergency stop switch is added to stop the operation of the device by pressing the switch. To prevent accidental operation of the emergency stop switch, a cylindrical protective sleeve is added to the emergency stop switch in the prior art. The cylindrical protective sleeve can protect the emergency stop button from being hit by the outside world, thereby preventing accidental contact.

[0004] However, the cylindrical protective sleeve is generally made of transparent plastic shell, which has low strength and is prone to breakage when hit by the outside world. At this time, the emergency stop switch has no protection, which may be pressed.

[0005] The existing one also sets the height of the protective sleeve higher than the emergency stop button, that is, the emergency stop button is installed in the groove, thereby achieving the effect of protecting the emergency stop switch

[0006] However, during use, the emergency stop switch has a certain diameter, and the protective sleeve also has a certain diameter. If some objects with a diameter smaller than the diameter of the protective sleeve are in contact with the emergency stop switch and are pressed, the emergency stop switch will be activated, reducing the effect of the protective sleeve.

[0007] Therefore, we propose a cover plate structure of emergency stop switch, which can improve the protection effect when the emergency stop switch is accidentally touched, and is simple and practical to operate. Content of the utility model

[0025] In order to make the purpose and advantages of the utility more clear and explicit, the utility is specifically described below in combination with examples. It should be understood that the following text is only used to describe one or several specific embodiments of the utility, and does not strictly limit the protection scope specifically requested by the utility.

[0026] As shown in Figures 1-4 , the technical scheme adopted by the utility is as follows: a cover plate structure of an emergency stop switch, comprising an installation cover plate 1, the installation cover plate 1 is provided with a protective sleeve 2 on one side, a mounting hole 8 is formed on the installation cover plate 1, an emergency stop switch body 3 is installed inside the mounting hole 8, a pressing disc 4 is arranged on the top of the emergency stop switch body 3,

[0027] As shown in Figure 4 , a circular groove 5 and a vertical groove 6 are formed on the inner wall of the protective sleeve 2, the circular groove 5 is communicated with the vertical groove 6, and a fixed rod 7 is rotatably arranged inside the circular groove 5, and the fixed rod 7 is connected with the pressing disc 4 on one side.

[0028] As shown in Figure 1 , a mounting hole 8 is formed on the installation cover plate 1, which is connected with the outside to fix the whole device to the outside.

[0029] Further, the emergency stop switch body 3 is movably installed on the installation cover plate 1 through the mounting hole 8, and this mode is clamping, which can facilitate the installation and disassembly of the emergency stop button body.

[0030] Further, the fixed rod 7 is movably connected with the pressing disc 4, and this mode is bolt connection or clamping, which can enable the emergency stop switch body 3 to be installed on the fixed rod 7, which is a prior art and will not be described in detail here.

[0031] It should be noted that the pressing disc 4 is part of the emergency stop switch body 3 and can rotate, and the emergency stop button can be pressed to stretch and contract, which is a prior art and will not be described in detail here.

[0032] Further, the circular groove 5 is matched with the fixed rod 7, and the fixed rod 7 can rotate in the circular groove 5.

[0033] Furthermore, the vertical groove 6 matches the fixed rod 7. When the fixed rod 7 rotates to the vertical groove 6, the pressing plate 4 can be pressed and extended, thereby making the emergency stop switch body 3 work.

[0034] like Figure 1 As shown, a sealing cover 9 is hinged to the outside of the protective cover 2. This design allows the sealing cover 9 to rotate, thereby sealing the protective cover 2 to prevent dust and water from entering, and also to achieve a certain degree of protection against accidental contact.

[0035] Furthermore, the sealing cap 9 is made of transparent material, making it easy for people to observe. At the same time, the sealing surface of the sealing cap 9 can be provided with an elastic sealing layer, which can improve the sealing effect.

[0036] Furthermore, multiple fixing rods 7 can be provided, so that they have high strength and are not easily damaged when subjected to external pressure.

[0037] Furthermore, when installing the emergency stop button, its height should be lower than the height inside the protective cover 2. This setting can prevent accidental activation.

[0038] It should be noted that the emergency stop switch should be installed from bottom to top.

[0039] Furthermore, the protective case 2 can also have markings on the outside to remind users of operating precautions.

[0040] The working principle of this utility model is as follows: When in use, the emergency stop switch body 3 is installed from bottom to top, and then the fixing rod 7 is used to fix the pressing plate 4. Upon impact, the device first provides protection through the sealing cover 9, achieving primary protection. When the sealing cover 9 is damaged or unusable, because the height of the emergency stop switch body 3 is lower than the internal height of the protective sleeve 2, the impacting object cannot contact the emergency stop switch body 3, thus achieving secondary protection. If an object smaller than the diameter of the protective sleeve 2 impacts, the impact force contacts the pressing plate 4. Because the pressing plate 4... The fixing rod 7 is limited inside the annular groove 5, so it will not move and the emergency stop switch body 3 will not be triggered, thus achieving three-fold protection. When the emergency stop switch body 3 needs to be used, simply open the sealing cover 9 and let the pressing plate 4 drive the fixing rod 7 to rotate inside the annular groove 5. When the fixing rod 7 rotates to the vertical groove 6, since there is no limitation from the annular groove 5, the emergency stop switch body 3 can be pressed and extended, thus making the emergency stop switch body 3 work. This utility model can improve the protection effect when the emergency stop switch is accidentally touched, and it is simple and practical to operate.

[0041] The above only is the preferred embodiment of the utility model, it should be pointed out, for ordinary skilled person in the art, without departing from the principle of the utility model, can make a number of improvements and refinements, these improvements and refinements also should be considered the protection scope of the utility model.The structure, device and operating method not specifically described and explained in the utility model, are implemented according to conventional means in the art, unless specifically described and limited.
