Description

Technical Field

[0001] The utility model belongs to the technical field of electric switch cabinet production equipment, and particularly relates to a switch cabinet infrared temperature measuring window fastening and installation tool. Background Art

[0002] An infrared temperature measurement window, also known as an infrared window, is installed on the switchgear panel. It is an optical observation window that transmits ultraviolet light, visible light, and infrared light. Using infrared thermal imagers and thermometers commonly used in power systems, various nondestructive tests can be conveniently performed through the infrared window on equipment inside electrical cabinets, identifying heating faults and enabling condition-based maintenance.

[0003] The infrared window is connected to the switchgear door panel via a threaded connection. However, since the switchgear inevitably generates continuous electrical vibration during use, if the threaded connection between the infrared window and the switchgear door panel is loose and severe, it can easily loosen. In severe cases, this can even cause the infrared optical crystal to fall off. Therefore, the infrared temperature measurement window must be tightened firmly during installation. Consequently, unscrewing the infrared temperature measurement window during maintenance is also quite laborious.

[0004] Traditional infrared temperature measurement windows rely on manual screwing, which is obviously very laborious. Chinese utility model patent CN 216030671 discloses an auxiliary installation tool for infrared temperature measurement windows. The tool comprises a mounting ring that matches the infrared temperature measurement window. One end of the mounting ring has a boss that fits into the notch of the infrared temperature measurement window. Positioning blocks are symmetrically arranged on the boss. During use, the positioning blocks fit into the notch at the edge of the infrared temperature measurement window, and one end of the mounting ring rests against the front surface of the cabinet. The infrared window can be tightened by twisting the handle firmly, improving installation quality and efficiency.

[0005] However, the structure of the above CN216030671 still has deficiencies: since the switch cabinet is not a standardized product, the infrared temperature measurement window has not yet formed a standardized system, and the diameters of the infrared temperature measurement windows are different. Therefore, among switch cabinet manufacturers, different diameter infrared temperature measurement windows require corresponding auxiliary installation tools, and the auxiliary installation tools are not universal, which makes management troublesome and inconvenient to find, use, and store tools. Utility Model Content

[0006] The purpose of the utility model is to overcome the above shortcomings and provide a switch cabinet infrared temperature measuring window fastening installation tool, which can be suitable for installing infrared temperature measuring windows of various diameters.

[0007] Its purpose can be achieved according to the following scheme: a switch cabinet infrared temperature measuring window fastening installation tool, including a handle, characterized in that the two ends of the handle are respectively fixedly connected to support legs vertically: the end of each support leg is fixedly connected to an arc-shaped support bar, and a protrusion is fixedly provided on the inner edge of each arc-shaped support bar, and the protrusions of the two arc-shaped support bars are symmetrically arranged; the handle is formed by overlapping two sections of handle units, and the two sections of handle units form a sliding connection; the first section of the handle unit is provided with a circular pin hole; the second section of the handle unit is provided with a plurality of circular adjustment holes of the same diameter, and each circular adjustment hole is arranged along the longitudinal direction of the second section of the handle unit, and the distance between the centers of each two adjacent circular adjustment holes is less than The diameter of the circular adjustment hole is larger than the radius of the circular adjustment hole, and each adjacent circular adjustment hole partially overlaps; a circular latch is also provided, which is inserted into the circular pin hole of the first section handle unit and one of the circular adjustment holes of the second section handle unit, and both ends of the circular latch are respectively provided with anti-falling components for preventing the circular latch from falling off from the circular pin hole and the circular adjustment hole; the circular latch includes an expanded diameter section and a reduced diameter section connected as one body, the diameter of the expanded diameter section of the circular latch is equal to the diameter of the circular pin hole of the first section handle unit and also equal to the diameter of the circular adjustment hole of the second section handle unit, and the diameter of the reduced diameter section of the circular latch is smaller than the width of the junction of the two adjacent circular adjustment holes of the second section handle unit.

[0008] The so-called "width of the boundary between two adjacent circular adjustment holes" refers to the width between the two intersection points of the contour lines of the two adjacent circular adjustment holes.

[0009] A return spring is sleeved on the outside of the circular latch, and the elastic force of the return spring causes the enlarged diameter section of the circular latch to be located in the circular adjustment hole of the second section handle unit.

[0010] An arc-shaped connecting bar is provided between the ends of the two arc-shaped support bars, and the arc-shaped support bar and the arc-shaped connecting bar are connected to form a ring; the arc-shaped connecting bar is provided with an arc-shaped long hole, and the ends of the two arc-shaped support bars are fixed with convex pins, and the convex pins of the two arc-shaped support bars are inserted into the arc-shaped long holes of the arc-shaped connecting bar.

[0011] The anti-falling component at one end of the circular latch is a cotter pin, and the anti-falling component at the other end is a pin cap, and the diameter of the pin cap is greater than the diameter of the main body section.

[0012] The utility model has the following advantages and effects:

[0013] 1. The utility model can adjust the length of the handle and the distance between the two protrusions according to the diameter specifications of the infrared temperature measuring window, so that the two protrusions of the fastening and installation tool can be embedded in the notches on the edges of infrared temperature measuring windows of different diameters, thereby realizing the universality of the fastening and installation tool and avoiding the problem that different fastening and installation tools are required for infrared temperature measuring windows of different diameters. This makes it easy to manage, use and store.

[0014] 2. Changing the handle length is easy to operate; when the handle length needs to be changed, one only needs to push the circular pin so that the reduced diameter section of the circular pin enters the circular adjustment hole of the second handle unit, so that the two handle units can slide relative to each other; when the adjustment is completed, the expanded diameter section of the circular pin enters the circular adjustment hole of the second handle unit, so that the two handle units can no longer slide relative to each other, and it is quite stable, and there is no need to use traditional methods such as thread compression to fix the handle length (if thread compression is used, each adjustment process requires the use of tools such as screwdrivers or wrenches to assist in tightening the threaded components, which is not very convenient to use).

[0015] 3. The round latch can be flexibly moved to adjust the position and will never fall or be lost. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Figure 1 、 Figure 2 、 Figure 3 The switch cabinet infrared temperature measuring window fastening installation tool shown includes a handle, which is formed by overlapping a first section handle unit 1 and a second section handle unit 2. The first section handle unit 1 and the second section handle unit 2 are overlapped to form a relatively sliding connection, specifically, the second section handle unit 2 is inserted into the first section handle unit 1; the two ends of the handle are respectively fixedly connected to support legs 4 vertically: the end of each support leg 4 is fixedly connected to an arc-shaped support bar 5, wherein the arc-shaped support bar 5 is integrally connected to a connecting piece 50, and the connecting piece 50 is connected to the first section handle unit 1. The support legs 4 on the corresponding sides are fixedly welded; an arc-shaped connecting bar 7 is also provided between the ends of the two arc-shaped support bars 5, and there are two arc-shaped connecting bars 7 in total. The arc-shaped support bars 5 and the arc-shaped connecting bars 7 are connected to form a ring; the arc-shaped connecting bar 7 is provided with an arc-shaped long hole 70, and the ends of the two arc-shaped support bars are fixed with a convex pin 71, and the convex pins 71 of the two arc-shaped support bars are inserted into the arc-shaped long hole 70 of the arc-shaped connecting bar; a protrusion 6 is fixed on the inner edge of each arc-shaped support bar 5, and the protrusions 6 of the two arc-shaped support bars are symmetrically arranged.

[0029] Figure 4 、 Figure 2 、 Figure 3 、 Figure 5 、 Figure 6 、 Figure 7 As shown, in the two-section handle unit, the first section handle unit 1 is provided with a circular pin hole 10; the second section handle unit 2 is provided with a plurality of circular adjustment holes 20 with the same diameter, each circular adjustment hole 20 is arranged along the longitudinal direction of the second section handle unit, and the center of each adjacent two circular adjustment holes 20 (such as Figure 5 The distance between the points M and N is smaller than the diameter of the circular adjustment hole 20 (as shown in FIG. Figure 5 The distance between the two points CD) is greater than the radius of the circular adjustment hole 20 (such as Figure 5 The distance between the two points of MC is such that the two adjacent circular adjustment holes 20 partially overlap (the overlapping part is as shown in FIG. Figure 51 and 2. As shown in the shaded area in the middle); a circular latch 3 is further provided, which is inserted into the circular pin hole 10 of the first section handle unit and one of the circular adjustment holes 20 of the second section handle unit; the circular latch 3 includes an expanded diameter section 31 and a reduced diameter section 32 connected as one body, the diameter of the expanded diameter section 31 of the circular latch being equal to the diameter of the circular pin hole 10 of the first section handle unit and also equal to the diameter of the circular adjustment hole 20 of the second section handle unit, and the diameter of the reduced diameter section 32 of the circular latch being smaller than the width of the junction of two adjacent circular adjustment holes 20 of the second section handle unit (the so-called "width of the junction of two adjacent circular adjustment holes" refers to the width between the two intersection points of the outlines of the two adjacent circular adjustment holes; as shown in FIG. Figure 4 、 Figure 5 In the figure, the two intersection points of the outlines of the adjacent circular adjustment holes are point E and point F), the purpose of which is to allow the reduced diameter section 32 to pass between point E and point F, so that the circular plug 3 can migrate between different circular adjustment holes 20 when necessary; in addition, both ends of the circular plug 3 are respectively provided with anti-falling components for preventing the circular plug from falling off from the circular pin hole 10 and the circular adjustment hole 20; the anti-falling component near the end of the expanded diameter section 31 is a pin cap 33, the diameter of the pin cap 33 is larger than the diameter of the expanded diameter section 31, and the anti-falling component near the end of the reduced diameter section 32 is a cotter pin 34, and an opening 30 for the cotter pin to pass through is provided at the end of the reduced diameter section 32; a return spring 35 is also sheathed on the outside of the circular plug 3, and the elastic force of the return spring 35 causes the expanded diameter section 31 of the circular plug to be located in the circular adjustment hole 20 of the second section handle unit, Figure 7 In the figure, the thrust direction of the return spring 35 on the circular latch 3 is shown as downward.

[0030] The operating principle of the above embodiment is as follows:

[0031] During operation, the arc-shaped support bar 5 is put on the outside of the infrared temperature measuring window 8, so that the protrusion 6 on the inner edge of each arc-shaped support bar 5 is embedded in the notch 80 on the edge of the infrared temperature measuring window 8, and the front end surface of the arc-shaped support bar 5 is close to the front surface of the cabinet door panel 9. Then, hold the handle tightly and twist it hard. Figure 9 、 Figure 12 shown.

[0032] When the diameter of the infrared temperature measuring window to be twisted is different, it is necessary to adjust the longitudinal length of the handle. First, the elastic force of the return spring 35 is overcome to push the circular plug 3 to move, so that the reduced diameter section 32 of the circular plug 3 enters the circular adjustment hole 20 of the second section handle unit 2. Figure 8As shown, since the diameter of the reduced diameter section 32 of the circular plug 3 is smaller than the width EF of the junction of two adjacent circular adjustment holes 20, the circular plug 3 can migrate between different circular adjustment holes 20, that is, the first section handle unit 1 and the second section handle unit 2 can move longitudinally relative to each other, thereby adjusting the longitudinal length of the handle, and at the same time adjusting the distance between the two protrusions 6, so that the two protrusions 6 can be embedded in the recesses on the opposite sides of the infrared temperature measuring window; after adjustment, the reset spring 35 is relaxed, so that the expanded diameter section 31 of the circular plug 3 enters the circular adjustment hole 20 of the second section handle unit 2. Since the diameter of the expanded diameter section 31 of the circular plug 3 is larger than the width EF of the junction of two adjacent circular adjustment holes 20, the circular plug 3 cannot migrate between different circular adjustment holes 20, that is, the first section handle unit 1 and the second section handle unit 2 cannot move longitudinally relative to each other, so the distance between the two protrusions 6 is fixed; a state before adjustment is shown as follows Figure 10 As shown, a state after adjustment is as follows Figure 11 shown.

[0033] During the above operation, when the worker twists the handle hard, if the force is too strong, it will inevitably generate additional forward pressure on the handle (the direction of the forward pressure may be as follows: Figure 12 As shown by the arrow f in the middle, this pressure will cause the handle to have an unstable tipping tendency (the central axis of the tipping action tendency is the line between the two protrusions 6, and the direction of the tipping tendency may be as follows Figure 12 As shown by the arc arrow, it tilts around the line between the two protrusions 6. Figure 12 On the other hand, due to the presence of the arc-shaped support bars 5 on both sides, the front end of the arc-shaped support bars 5 is against the cabinet door panel 9, so this tipping tendency can be prevented; in other words, the arc-shaped support bars 5 have the function of being sheathed around the infrared temperature measuring window 8 to facilitate positioning and prevent slipping, and the function of the other side is to prevent the entire fastening installation tool from tipping over during the process of twisting the handle hard, and to support the entire fastening installation tool, such as Figure 12 As shown, workers can freely apply twisting force without being afraid to freely apply twisting force due to the above-mentioned tipping tendency.
