Description

Technical Field

[0001] The utility model relates to the technical field of operating columns, and specifically relates to an operating column. Background Art

[0002] The operating column is used to control the start, stop and emergency stop of the motor, so as to realize the control of the motor, which is abbreviated as the explosion-proof starting box beside the machine. Usually, the electrical control of the equipment is carried out on the control boxes and cabinets specially set in the control room for start-stop operation and operation status display. There are still some problems with the existing waterproof operating columns. One is that the quality of the sealing material is unstable, and safety problems such as aging and leakage are likely to occur after long-term use. The other is that the sealing method is single, resulting in an unsatisfactory waterproof effect. Therefore, in the patent application No. CN202320668315.8, "a waterproof operating column" is disclosed, which plays a waterproof role by filling the gaps in the operating box.

[0003] However, it still cannot reduce the aging of the operating box by the outside world, and the explosion-proof effect of this operation is poor. Once an explosion occurs, it directly relies on the thin plate surface of the operating box to resist, resulting in poor anti-deformation ability and easy cracking, thus making the explosion-proof performance weak. Content of the Utility Model

[0004] The purpose of the utility model is to solve the defects existing in the prior art, and to propose an operating column to solve the problem of weak explosion-proof performance.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] An operating column includes a column rod, a control box is fixedly installed at the top of the column rod, a protective cover is slidably connected to the outside of the control box, sliders are fixedly connected to both sides inside the protective cover, sliding grooves are opened on both sides of the control box, the sliders slide in the sliding grooves, a clamping component is arranged on the surface of the control box, a clamping groove is penetrated through the surface of the protective cover, and the clamping component is clamped in the clamping groove.

[0007] Preferably, the clamping component includes a movable groove opened on the control box, a spring is installed in the movable groove, and a clamping block is fixedly installed at the end of the spring.

[0008] Preferably, the column rod includes a sleeve and a movable cylinder, the movable cylinder moves inside the sleeve, and a fastening bolt is threadedly installed on the side surface of the sleeve.

[0009] Preferably, a wire is connected to the bottom of the control box, and the wire penetrates through the column rod.

[0010] Preferably, a base is fixedly installed at the bottom of the column rod, and fixing nails are installed on the base.

[0011] In summary, the beneficial effects of the present utility model are as follows: An operating column provided by the present utility model can use a clamping component to be clamped and limited by a clamping groove when the operating box slides up, which is simple and convenient to use. When the protective cover covers the operating box, it can not only protect the operating box from rain and water, but also strengthen the peripheral protection of the operating box, playing a better explosion-proof role, solving the problem of relatively weak explosion-proof performance of the current operating column, slowing down the aging of the operating box, and playing a role in waterproofing and rainproofing.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0017] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0018] Such as Figure 1 - Figure 3As shown in the figure, an operating column provided by the utility model includes a column rod 1. A control box 2 is fixedly installed at the top of the column rod 1. A protective cover 3 is slidably connected to the outside of the control box 2. Sliders 4 are fixedly connected to both sides inside the protective cover 3. Chute grooves 5 are formed on both sides of the control box 2. The sliders 4 slide in the chute grooves 5. A clamping component 6 is arranged on the surface of the control box 2. A clamping groove 7 is formed through the surface of the protective cover 3. The clamping component 6 is clamped in the clamping groove 7.

[0019] The column rod 1 provides support. A switch is arranged inside the control box 2, and buttons of the switch are arranged outside. It can operate and control electrical components. The provided protective cover 3 can protect the control box 2, and can slide through the cooperation of the arranged sliders 4 and chute grooves 5. When the control box 2 slides up, the clamping component 6 can be clamped in the clamping groove 7 for clamping and limiting.

[0020] The provided protective cover 3 is integrally designed, and it has only an opening at the bottom surface. When the protective cover 3 covers the control box 2, it can not only play a role in rain and water protection for the control box 2, but also strengthen the peripheral protection of the control box 2, playing a better explosion-proof role.

[0021] The clamping component 6 includes a movable groove 61 formed on the control box 2. A spring 62 is installed in the movable groove 61. A clamping block 63 is fixedly installed at the end of the spring 62.

[0022] When the protective cover 3 slides up, the clamping block 63 is clamped in the clamping groove 7 under the action of the spring 62, so as to limit the protective cover 3.

[0023] The column rod 1 includes a sleeve 11 and a movable cylinder 12. The movable cylinder 12 moves inside the sleeve 11. A fastening bolt 13 is threadedly installed on the side surface of the sleeve 11.

[0024] The provided movable cylinder 12 can move inside the sleeve 11 and is fastened by the fastening bolt 13, so as to adjust the height of the control box 2, which is more convenient for workers of different heights to operate.

[0025] A wire 8 is connected to the bottom of the control box 2. The wire 8 penetrates through the column rod 1.

[0026] The wire 8 can be hidden inside the column rod 1 to reduce the mess of wire arrangement. When the column rod 1 is adjusted in height, the wire 8 is not affected either.

[0027] A base 9 is fixedly installed at the bottom of the column rod 1. Fixing nails 10 are installed on the base 9.

[0028] The provided base 9 plays a stabilizing role, and the fixing nails 10 can strengthen the fixing effect.

[0029] Working principle: When in use, place this operating column and strengthen the fixation by using the fixing nails 10. Adjust the height of the movable cylinder 12 in the sleeve 11 and tighten it by using the fastening bolt 13, so that the height of the operating box 2 can be adjusted. The provided protective cover 3 can protect the operating box 2, and the cooperation of the provided slider 4 and the chute 5 enables sliding. When the operating box 2 slides up, it can be clamped and limited by the clamping component 6 and the clamping groove 7. When not in use, the limit can be cancelled by pressing the clamping block 63 of the clamping component 6, and the protective cover 3 is slid down, so that the operating box 2 can be protected.
