Description

Technical Field

[0001] This utility model relates to the field of instrumentation technology, specifically to an automatic control instrument that is easy to install. Background Technology

[0002] An automated instrument is a relatively complete automated technology tool composed of several automated components. It generally has several functions simultaneously, such as measurement, display, recording, or measurement, control, and alarm. An automated instrument is itself a system, and also a subsystem within the overall automation system. An automated instrument is an "information machine," whose main function is the conversion of information form, transforming input signals into output signals. Signals can be expressed in the time domain or frequency domain, and signal transmission can be modulated into continuous analog quantities or discontinuous digital quantities.

[0003] Currently, existing automatic control instruments that are easy to install are usually fixed with bolts. However, using screws requires additional tools for installation and removal, making installation inconvenient. Therefore, we propose an automatic control instrument that is easy to install. Utility Model Content

[0004] The purpose of this utility model is to provide an easy-to-install automatic control instrument, which has the advantage of easy installation and solves the problem that existing easy-to-install automatic control instruments are usually fixed by bolts, while screw installation requires additional tools for installation and removal, which makes the installation inconvenient.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an easy-to-install automatic control instrument, including a mounting base, with grooves on both the front and rear sides of the inner cavity of the mounting base, a fixing rod fixedly connected to the inner side of the groove, a guide sleeve sleeved at the middle end of the outer surface of the fixing rod, positioning plates fixedly connected to both sides of the outer surface of the guide sleeve, torsion springs sleeved on the outside of the fixing rod fixedly connected between the top and bottom of the guide sleeve and the top and bottom of the inner side of the groove, and a pressing block movably connected to one end of the inner side of the groove to abut against the positioning plates, mounting holes on both the left and right ends of the rear side of the mounting base, an instrument body disposed on the inner side of the mounting base, and positioning slots adapted to the positioning plates on both the left and right sides of the instrument body.

[0006] Preferably, hinge pins are fixedly connected to both the left and right sides of the upper end of the mounting base, and a protective cover is hinged to the outer side of the hinge pin.

[0007] Preferably, an iron metal plate is fixedly connected to the lower right side of the protective cover, a pull block is fixedly installed at the lower left side of the protective cover, and a magnet corresponding to the iron metal plate is embedded at the lower left side of the mounting base.

[0008] Preferably, the longitudinal section of the positioning groove is a right-angled triangle.

[0009] Preferably, the bottom of the mounting base is provided with an adjustment groove, and the upper end of the inner cavity of the adjustment groove is movably connected to a bidirectional threaded rod through a bearing. The right end of the bidirectional threaded rod passes through the right side of the mounting base, and a rotating block is fixedly connected to the right side of the bidirectional threaded rod.

[0010] Preferably, both the left and right ends of the outer surface of the bidirectional threaded rod are threaded with movable plates, and both the front and rear ends of the bottom of the movable plates are hinged with connecting rods. A movable wheel is movably connected to the inner side of the connecting rod away from the movable plate.

[0011] Preferably, guide grooves are provided at both ends of the front and rear sides of the inner cavity of the mounting base, and a guide slider that slides in the guide groove is fixedly connected to the end of the connecting rod away from the moving plate and the side of the connecting rod near the inner wall of the adjustment groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. When the instrument body enters the mounting base, the left and right sides of the instrument body can contact the positioning plate, pushing the positioning plate to drive the guide sleeve to rotate around the fixed rod. When the guide sleeve rotates, it can drive the torsion spring to contract. After the rear side of the instrument body contacts the rear side of the mounting base cavity, the contracted torsion spring can drive the guide sleeve to rotate in the opposite direction around the fixed rod. The repositioned positioning plate can be locked into the positioning buckle groove, thus confining the instrument body within the mounting base, thereby achieving quick installation of the instrument body. When it is necessary to disassemble the instrument body, simply press the positioning plate that is in contact with the pressure block to move inward. Then, the positioning plate can drive the guide sleeve to rotate around the fixed rod, and drive the torsion spring to contract again, so that the corresponding positioning plate can be disengaged from the positioning buckle groove. Thus, the instrument body can be removed from the mounting base, which is convenient for the operator.

[0014] 2. When the protective cover is flipped upwards around the hinge pin by the pull block, the instrument body can be easily accessed after the protective cover is opened. After use, when the protective cover is flipped downwards around the hinge pin by the pull block to reset, the magnet can attract the ferrous metal plate and thus position the protective cover. The positioned protective cover can provide shielding protection on the outside of the instrument body, preventing the instrument body from being bumped or damaged. Attached Figure Description

[0026] Example 1

[0027] Please see Figures 1-6 As shown, this utility model provides a technical solution: an easy-to-install automatic control instrument, including a mounting base 1. Grooves 22 are provided on both the front and rear sides of the inner cavity of the mounting base 1. A fixing rod 21 is fixedly connected to the inner side of the groove 22. A guide sleeve 14 is sleeved on the middle end of the outer surface of the fixing rod 21. Positioning plates 19 are fixedly connected to both sides of the outer surface of the guide sleeve 14. Torsion springs 20, sleeved on the outside of the fixing rod 21, are fixedly connected between the top and bottom of the guide sleeve 14 and the top and bottom of the inner side of the groove 22. A pressing block 4, which abuts against the positioning plate 19, is movably connected to one end of the inner side of the groove 22. Mounting holes 5 are provided on both the left and right ends of the rear side of the mounting base 1. An instrument body 9 is provided inside the mounting base 1. Positioning slots 13, which are adapted to the positioning plates 19, are provided on both the left and right sides of the instrument body 9. The longitudinal section of the positioning slots 13 is a right-angled triangle.

[0028] This technical solution: Through the installation hole 5, the mounting base 1 can be installed in the usage position using bolts. Then, when the instrument body 9 enters the inner side of the mounting base 1, the left and right sides of the instrument body 9 can contact the positioning plate 19, pushing the positioning plate 19 to drive the guide sleeve 14 to rotate around the fixed rod 21. As the guide sleeve 14 rotates, it can cause the torsion spring 20 to contract. After the rear side of the instrument body 9 contacts the rear side of the inner cavity of the mounting base 1, the contracted torsion spring 20 can drive the guide sleeve 14 to rotate around the fixed rod 21, causing the positioning plate 19 to reset in the opposite direction.

A pull block 6 is fixedly installed at the lower left side of the protective cover 3. A magnet 10 corresponding to the iron metal plate 7 is embedded at the lower left side of the mounting base 1.

[0031] This technical solution: When the protective cover 3 is rotated upward around the hinge pin 2 by the pull block 6, the instrument body 9 can be easily used after the protective cover 3 is opened. After use, when the protective cover 3 is rotated downward around the hinge pin 2 by the pull block 6 to reset, the magnet 10 can attract the iron metal plate 7, thereby positioning the protective cover 3. The positioned protective cover 3 can provide shielding protection on the outside of the instrument body 9, avoiding the occurrence of bumps and knocks on the instrument body 9.

[0032] Example 3

[0033] Based on Embodiment 1, this utility model is as follows: Figures 1-6As shown, the bottom of the mounting base 1 is provided with an adjustment groove 11.
