Description

Technical Field

[0001] The utility model relates to the technical field of thermal instruments, in particular to a thermal instrument installation and fastening device. Background Art

[0002] Thermal measuring instruments are a general term for various instruments used to measure thermal parameters (such as temperature, pressure, flow, liquid level, etc.), and are especially widely used in thermal power plants. Thermal instruments need to be fixed in various places so that staff can observe and monitor data. However, the traditional fixing method is not conducive to the rapid disassembly of thermal instruments. Once a thermal instrument fails and needs to be disassembled for maintenance, it takes a long time to disassemble and assemble, which not only increases the burden on staff, but also has a great impact on the normal operation of the thermal power plant. In addition, the current fixing devices for thermal instruments are often relatively single in applicability, which is not conducive to the installation of thermal instruments of different models and types, and has great limitations in use. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a thermal instrument installation and fastening device for the above-mentioned technical deficiencies, which can facilitate the rapid disassembly and assembly of thermal instruments, can adapt to thermal instruments of various models and types, and has wide applicability.

[0004] The technical solution adopted by the utility model is: to provide a thermal instrument installation and fastening device, comprising an annular installation base; the axial direction of the installation base is arranged along the vertical direction; a plurality of positioning hole plates are fixed on the outer side of the installation base along the circumferential direction; a plurality of through holes are opened radially on the side of the installation base; the plurality of through holes are evenly distributed on the installation base along the circumferential direction; an abutment rod is slidably sleeved in the through hole; a pressing mechanism for positioning the abutment rod is arranged on the installation base;

[0005] The pressing mechanism includes a plurality of slots uniformly arranged along the circumferential direction at the upper end of the mounting base; the upper side of the through-channel passes through the lower side of the slots; the slots are each provided with a pressing block inserted in a vertical sliding manner; the outer side of the pressing block is provided with a bracket fixed to the mounting base; a fixing screw is passed through the upper end of the bracket along the vertical thread; the lower end of the fixing screw corresponds to the middle part of the upper end of the corresponding pressing block.

[0006] To further optimize the technical solution, a rubber pad is fixed to one end of an abutment rod of a thermal instrument installation and fastening device close to the axis of the installation base.

[0007] To further optimize the technical solution, a compression spring is connected between the upper end of a bracket of a thermal instrument installation and fastening device and the upper end of a compression block.

[0008] To further optimize the technical solution, a mounting base of a thermal instrument mounting and fastening device has an annular mounting groove coaxially opened on the inner side of the upper end; a transparent cover shell is threadedly connected to the inner side of the mounting groove.

[0009] To further optimize the technical solution, a fixing screw of a thermal instrument installation and fixing device is rotatably connected to a cushion block at the lower end; the cushion block abuts against the upper end of the corresponding pressing block.

[0010] To further optimize the technical solution, an abutment rod of a thermal instrument installation and fastening device is a rubber-coated structure.

[0011] To further optimize the technical solution, a handle is fixed on the upper end of a compression block of a thermal instrument installation and fastening device.

[0012] To further optimize the technical solution, the bottom end of a compression block of a thermal instrument installation and fastening device is a frosted structure.

[0015] The beneficial effects of the utility model are:

[0016] 1. The mounting base can be easily fixed at the required installation position through the positioning hole plate, and then the thermal instrument can be installed and fixed through the mounting base; the space in the middle of the annular mounting base can be used to install the thermal instrument.

[0017] 2. By evenly distributing abutment rods on the mounting base in the circumferential direction of the through-hole and slidingly sleeved in the through-hole, the thermal instrument can be clamped in the middle of the mounting base by adjusting the abutment rods distributed circumferentially in the through-hole separately.

[0018] 3. The upper side of the through-hole passes through the lower side of the slot, and a compression block is inserted in the slot along the vertical sliding direction. A fixing screw is passed through the upper end of the bracket along the vertical thread.

[0022] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] like Figure 1-2 As shown, a thermal instrument mounting and fastening device comprises an annular mounting base 1; the axial direction of the mounting base 1 is arranged along the vertical direction; a plurality of positioning hole plates 2 are fixed to the outer side of the mounting base 1 along the circumferential direction; a plurality of through holes 3 are opened radially on the side of the mounting base 1; the plurality of through holes 3 are evenly distributed on the mounting base 1 along the circumferential direction; an abutment rod 4 is slidably sleeved in the through hole 3; a pressing mechanism for positioning the abutment rod 4 is arranged on the mounting base 1;

[0024] The pressing mechanism includes a plurality of slots 5 uniformly arranged along the circumferential direction at the upper end of the mounting base 1; the upper side of the through-channel 3 passes through the lower side of the slots 5; the slots 5 are each provided with a pressing block 6 inserted in a vertical sliding manner; the outer side of the pressing block 6 is provided with a bracket 7 fixed to the mounting base 1; a fixing screw 8 is passed through the upper end of the bracket 7 along a vertical thread; the lower end of the fixing screw 8 corresponds to the middle part of the upper end of the corresponding pressing block 6.

[0025] In the present technical solution, the thermal instrument is first placed into the space in the middle of the mounting base 1, and then the fixing screws 8 are screwed to release the pressure on the compression block 6, so that the compression block 6 releases the pressure on the abutment rod 4, allowing the abutment rod 4 to slide easily along the through-hole 3. Through this operation, all the abutment rods 4 can cooperate to clamp the thermal instrument on the mounting base 1, and the fixing screws 8 are re-pressurized to achieve the compression and locking of the abutment rod 4 by the compression block 6, ensuring that the abutment rod 4 can firmly clamp the thermal instrument.

[0026] The device clamps the thermal instrument by abutting against multiple abutment rods 4, so it is more convenient to install thermal instruments of various types and models, and has a wide range of applicability. Moreover, when the thermal instrument is disassembled and installed between the mounting base 1, the operation is more convenient and quick. In addition, the mounting angle requirement for the mounting base 1 is also low. Even if the mounting base 1 is installed on a wall or other position, the mounting angle is skewed, and the thermal instrument can also conveniently adjust the angle of the clamping and fixing to ensure that the thermal instrument can be installed accurately.

[0027] like Figure 2As shown, a rubber pad 10 is fixed to one end of the abutment rod 4 close to the axis of the mounting base 1. The rubber pad 10 can improve the stability of the thermal instrument clamping, and can play a buffering effect to reduce the wear caused by the thermal instrument housing clamping.

[0028] like Figure 2 As shown, a compression spring 11 is connected between the upper end of the bracket 7 and the upper end of the compression block 6. When the fixing screw 8 is tightened to release the pressure on the compression block 6, the pre-tightening force of the compression spring 11 can still ensure a certain pressure on the compression block 6, so that the abutment rod 4 can still maintain a stable clamping of the thermal instrument at this time, so as to prevent the thermal instrument from falling and being damaged when the fixing screw 8 is loosened.

[0029] like Figure 1-2 As shown, a circular mounting groove 13 is coaxially opened on the inner side of the upper end of the mounting base 1; a transparent cover 14 is threadedly connected to the mounting groove 13. The transparent cover 14 can shield the thermal instrument and improve the protection effect of the thermal instrument. It should be noted that Figure 2 In order to clearly show the structure of the transparent cover 14, it is not shown transparently.

[0030] like Figure 2 As shown, the lower end of the set screw 8 is rotatably connected to a cushion block 9, which abuts against the upper end of the corresponding pressing block 6. The cushion block 9 rotates with the set screw 8 to avoid wear between the set screw 8 and the pressing block 6 when the set screw 8 applies pressure to the pressing block 6.

[0031] The abutment rod 4 is a rubber-coated structure. When the abutment rod 4 is frequently pulled out, the problem of wear of the through-hole 3 can be alleviated.

[0032] like Figure 1-2 As shown, a handle 12 is fixed to the upper end of the compression block 6. The handle 12 can be used to conveniently pull the compression block 6 to appropriately overcome the preload force of the compression spring 11, thereby releasing the pressure of the compression block 6 on the abutment rod 4 and achieving the movement of the abutment rod 4.

[0033] The bottom end of the pressing block 6 is a frosted structure, which can increase the friction between the pressing block 6 and the abutment rod 4 after the two are pressed, thereby improving the firmness of the positioning of the abutment rod 4.

[0034] The side of the pressing block 6 is coated with Teflon coating, which facilitates smoother movement of the pressing block 6 and the slot 5.

[0035] The distance between the upper end of the compression block 6 and the lower end of the bracket 7 is smaller than the depth of the slot 5, which can prevent the compression block 6 from falling out of the slot 5 when it is lifted upward.

In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention.
