Description

Technical Field

[0001] This utility model relates to the field of operating column technology, specifically to an explosion-proof operating column. Background Technology

[0002] An explosion-proof operating column is an explosion-proof control box for controlling a motor with a support column. It includes start and emergency stop buttons, indicator lights, ammeters, voltmeters, frequency meters, and other structures. Explosion-proof operating columns can be used when there is no wall nearby for the operating column to be installed, or when ordinary button boxes do not meet safety requirements.

[0003] The explosion-proof operating column uses a support column and base to install the control box in a designated position for use. However, in the existing structure, the control box is fixedly installed on the top of the support column. The height of the control box is fixed, so the height of the control box cannot be adjusted, which limits the operation of the explosion-proof operating column for operators. Utility Model Content

[0004] Based on the above problems, the purpose of this utility model is to provide an adjustable and easy-to-store explosion-proof operating column.

[0005] To address the above problems, the following technical solution is provided: an explosion-proof operating column, including a control box, an adjusting column connected to the control box, a support column sleeved outside the adjusting column, an adjusting sleeve screwed into the adjusting column, and a base connected to the bottom end of the support column. The outer circumferential wall of the bottom end of the adjusting column has an external thread. The top end of the support column has a connector with an outer diameter smaller than the outer diameter of the support column. The adjusting sleeve has a sleeve opening adapted to the connector. One end of the adjusting sleeve relative to the support column has an adjusting hole with an inner diameter smaller than the inner diameter of the sleeve opening. The adjusting hole has an internal thread adapted to the external thread of the adjusting column. The adjusting column achieves axial displacement relative to the support column through the rotation of the adjusting sleeve.

[0006] In the above structure, the operator holds the adjusting column with one hand and uses the other hand to rotate the adjusting sleeve, which engages with the adjusting column via a threaded connection, controlling the column's upward or downward movement. This allows the height of the control box from the ground to be adjusted, improving the ease of operation and allowing for adjustments based on different operator heights or installation conditions, thus expanding the applicability of this invention. The connector facilitates the installation of the adjusting sleeve through the sleeve opening, improving its installation and support, and enhancing the reliability of this invention. Inserting the bottom end of the adjusting column into the support column facilitates the assembly and disassembly of the adjusting column and support column, making it easy to store, pack, and transport this invention, saving packaging space.

[0007] The present invention is further configured such that a limiting ring protrudes from the outer circumferential wall of the adjusting column, and the opening length of the external thread is from the bottom end of the adjusting column to the end of the limiting ring near the support column.

[0008] In the above structure, the adjustment stroke of the adjusting column can be controlled by setting a limit ring, which makes it easier for the operator to make adjustments and improves the ease of operation of this utility model.

[0009] The present invention is further configured such that a concave limiting groove is provided on the outer circumferential wall of the adjusting column, and a limiting ridge adapted to the limiting groove is provided on the inner wall of the supporting column.

[0010] In the above structure, the matching of the limiting ridge and the limiting groove facilitates the positioning and installation of the adjusting column, and also facilitates the limiting of the circumferential rotation of the adjusting column, thereby improving the stability of the adjusting column. Furthermore, it allows the operator to control the axial reciprocating movement of the adjusting column relative to the support column through the adjusting sleeve, thus improving the ease of operation of this utility model.

[0011] The present invention is further configured such that two sets of limiting grooves and limiting edges are symmetrically arranged in the axial direction of the adjusting column.

[0012] The above structure improves the stability of the adjustment column displacement, thereby enhancing the reliability of this invention.

[0013] The present invention is further configured such that a limiting block is formed at the bottom end of the support column in the radial direction, an installation hole adapted to the support column is formed on the base, an installation groove corresponding to the limiting block is formed on the outside of the installation hole on the base, and a positioning groove for the limiting block to be screwed in is formed on the inner wall of the installation hole.

[0014] In the above structure, after the support column is installed into the mounting groove on the base by the limiting block, it is rotated so that the limiting block enters the positioning groove, thereby making the support column and the base engage and cooperate, which facilitates the assembly and disassembly of the two, and thus facilitates the storage and transportation of this utility model.

[0015] The present invention is further configured such that four limiting blocks are provided in the circumferential direction relative to the supporting column.

[0016] By adopting the above structure, the stability of the support column can be improved, thereby improving the reliability of this utility model.

[0017] The present invention is further configured such that the limiting block has a rounded edge on the side facing the screw-in direction.

[0018] The above structure facilitates the entry of the limiting block into the positioning groove, thereby improving the ease of assembly of this utility model.

[0019] The present invention is further configured such that a plug sleeve is fitted on the support column, and a plug block corresponding to the mounting groove is provided at one end of the plug sleeve facing the base.

[0020] In the above structure, after the support column and the base are engaged, the plug sleeve is moved to insert the plug block into the mounting groove, which can limit the position of the limiting block and seal the mounting groove, thereby improving the tightness between the support column and the base and improving the stability of this utility model.

[0021] The present invention is further configured such that the plug sleeve and the plug block are integrally formed and are made of rubber.

[0022] The above structure can further improve the tightness between the support column and the base, thereby improving the sealing of the connection between the base and the support column, enhancing the waterproof and dustproof effect of both, and extending their service life.

Detailed Implementation

[0028] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0029] It should be noted that all directional indicators (such as up, down, left, right, front, back, back, etc.) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0030] like Figures 1 to 4The explosion-proof operating column shown includes a control box 1, an adjusting column 2 connected to the control box 1, a support column 3 sleeved on the outside of the adjusting column 2, an adjusting sleeve 4 screwed to the adjusting column 2, and a base 5 connected to the bottom end of the support column 3. The outer circumferential wall of the bottom end of the adjusting column 2 is provided with an external thread. The top end of the support column 3 is provided with a connector 31 with an outer diameter smaller than the outer diameter of the support column 3. The adjusting sleeve 4 is provided with a sleeve opening 41 adapted to the connector 31. The end of the adjusting sleeve 4 relative to the support column 3 is provided with an adjusting hole 42 with an inner diameter smaller than the inner diameter of the sleeve opening 41. The adjusting hole 42 is provided with an internal thread adapted to the external thread of the adjusting column 2. The adjusting column 2 achieves axial displacement relative to the support column 3 by rotating the adjusting sleeve 4.

[0031] In the above structure, the operator holds the adjusting column 2 with one hand and uses the other hand to rotate the adjusting sleeve 4, which engages with the adjusting column 2 via a threaded connection, controlling the upward or downward movement of the adjusting column 2. This allows the height of the control box 1 from the ground to be adjusted, improving the ease of operation and allowing for adjustments based on the height of different operators or installation conditions, thus expanding the applicability of this invention. The connecting head 31 facilitates the installation of the adjusting sleeve 4 through the sleeve opening 41, improving its installation and support, and enhancing its reliability. Inserting the bottom end of the adjusting column 2 into the support column 3 facilitates the assembly and disassembly of the adjusting column 2 and the support column 3, making it easy to store, pack, and transport this invention, saving packaging space.

[0032] In this embodiment, a limiting ring 21 protrudes from the outer circumferential wall of the adjusting column 2, and the opening length of the external thread is from the bottom end of the adjusting column 2 to the end of the limiting ring 21 near the support column 3.

[0033] In the above structure, the adjustment stroke of the adjusting column 2 can be controlled by setting the limiting ring 21, which makes it easier for the operator to make adjustments and improves the convenience of operation of this utility model.

[0034] In this embodiment, the outer circumferential wall of the adjusting column 2 is provided with a concave limiting groove 22, and the inner wall of the supporting column 3 is provided with a limiting ridge 32 that matches the limiting groove 22.

[0035] In the above structure, the positioning and installation of the adjusting column 2 can be facilitated by the cooperation of the limiting ridge 32 and the limiting groove 22, and the circumferential rotation of the adjusting column 2 can be limited, thereby improving the stability of the adjusting column 2. It also makes it easier for the operator to control the axial reciprocating movement of the adjusting column 2 relative to the supporting column 3 through the adjusting sleeve 4, thus improving the convenience of operation of this utility model.

[0036] In this embodiment, the limiting groove 22 and the limiting ridge 32 are arranged symmetrically in the axial direction relative to the adjusting column 2 in two sets.

[0037] By adopting the above structure, the stability of the displacement of the adjusting column 2 is improved, thereby improving the reliability of this utility model.

[0038] In this embodiment, a limiting block 33 is provided at the bottom end of the support column 3 in the radial direction. The base 5 is provided with an installation hole 51 that is adapted to the support column 3. An installation groove 52 corresponding to the limiting block 33 is provided on the outside of the installation hole 51 on the base 5. A positioning groove 53 for the limiting block 33 to be screwed into is provided on the inner wall of the installation hole 51.

[0039] In the above structure, after the support column 3 is installed into the mounting groove 52 on the base 5 through the limiting block 33, it is rotated so that the limiting block 33 enters the positioning groove 53, thereby making the support column 3 and the base 5 engage and cooperate, which facilitates the assembly and disassembly of the two, and thus facilitates the storage and transportation of this utility model.

[0040] In this embodiment, four limiting blocks 33 are provided in the circumferential direction relative to the support column 3.

[0041] By adopting the above structure, the stability of the support column 3 can be improved, thereby improving the reliability of this utility model.

[0042] In this embodiment, the limiting block 33 has a rounded edge on the side facing the screw-in direction.

[0043] The above structure facilitates the entry of the limiting block 33 into the positioning groove 53, thereby improving the ease of assembly of this utility model.

[0044] In this embodiment, a plug sleeve 6 is fitted on the support column 3, and a plug block 61 corresponding to the mounting groove 52 is provided at one end of the plug sleeve 6 facing the base 5.

[0045] In the above structure, after the support column and the base 5 are engaged, the plug sleeve 6 is moved to insert the plug block 61 into the mounting groove 52, which can limit the position of the limiting block 33 and seal the mounting groove 52, thereby improving the tightness between the support column 3 and the base 5 and improving the stability of this utility model.

[0046] In this embodiment, the plug sleeve 6 and the plug block 61 are integrally formed and are made of rubber.

[0047] The above structure can further improve the tightness between the support column 3 and the base 5, thereby improving the sealing of the connection between the base 5 and the support column 3, enhancing the waterproof and dustproof effect between the two, and extending their service life.

[0048] In this embodiment, the plug 61 is solid or hollow.

[0049] In the above structure, by setting the plug 61 to a hollow state, a counterweight can be placed inside it, thereby improving the stability of the base.

[0050] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model. These improvements and modifications assumed above should also be considered within the protection scope of the present utility model.
