[0027] In order to make the purpose, technical solutions and advantages of the present application more clear, the following will combine the drawings in the preferred embodiments of the present application to describe the technical solutions in the embodiments of the present application in more detail. In the drawings, the same or similar reference signs represent the same or similar components or components with the same or similar functions throughout. The described embodiments are some embodiments of the present application, not all embodiments. The embodiments described below by referring to the drawings are exemplary, and are intended to explain the present application, and cannot be understood as the limitation of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application. The embodiments of the present application will be described in detail below by combining the drawings.

[0028] In the description of the application, it is necessary to point out that, unless otherwise explicitly specified and limited, the terms "mount", "connect", "connection" should be understood in a broad sense, for example, can be fixedly connected, can be indirectly connected through an intermediate medium, can be the internal communication of two elements or the interaction relationship of two elements. For those skilled in the art, the specific meaning of the above terms in the application can be understood according to the specific circumstances.

[0029] In the description of the application, it is necessary to understand that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship of the drawings, and are only for the convenience of describing the application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the application.

[0030] The terms "first", "second", "third" (if any) in the specification and claims of the application and the above drawings are used to distinguish similar objects, and do not necessarily describe a particular order or sequence.

[0031] In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or display including a series of steps or units does not have to be limited to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to these processes, methods, products or displays.

[0032] In the prior art, in the process of measuring with a multimeter, the worker needs to hold the positive and negative test pens of the multimeter with both hands and place the contacts of the positive and negative test pens at the place to be measured. However, when the measurement space is limited, the worker's hands cannot reach into the place to be measured to fix the positive and negative test pens of the multimeter, or the worker's hands holding the positive and negative test pens reach into the place to be measured, which is easy to touch the live equipment, and there is a safety risk.

[0033] After repeated thinking and verification, the inventor finds that if a auxiliary support is designed, the positive and negative electrodes of the multimeter can be fixed by the auxiliary support, a protection strip is arranged on the auxiliary support, and the protection strip can be extended or retracted relative to the auxiliary support. When the measurement space is limited, the positive and negative electrodes can be driven by the auxiliary support to extend into the position to be measured, and in the process of extension, the protection strip can avoid the contacts on the electrodes from contacting other measurement points. After the positive and negative electrodes extend to the preset position, the protection strip can be retracted, and the contacts of the positive and negative electrodes are contacted with the measurement point to be measured to realize measurement. The staff does not need to directly hold the positive and negative electrodes, and the multimeter can be used for measurement when the measurement space is limited, and the safety risk in the measurement process can be reduced.

[0034] Therefore, the inventor designs a multimeter measurement auxiliary support, which comprises two support units and a connecting assembly connected between the two support units. The support unit comprises a cylinder and a protection strip movably mounted in the cylinder. The electrodes of the multimeter can be mounted on the outer side of the cylinder through a fixing member, and the protection strip can move relative to the cylinder between a first position and a second position. After the electrodes are connected with the cylinder, the contacts of the electrodes exceed the end of the cylinder. When the protection strip is located at the first position, the end of the protection strip exceeds the contacts. When the protection strip is located at the second position, the contacts exceed the end of the protection strip. When the measurement space is limited, the staff can hold the connecting assembly to drive the positive and negative electrodes to extend into the position to be measured. In the process of extension, the protection strip is located at the first position. After the positive and negative electrodes reach the preset position, the protection strip is adjusted to move from the first position to the second position. After the contacts of the positive and negative electrodes are contacted with the measurement point to be measured, the measurement can be realized. The staff does not need to directly hold the positive and negative electrodes, and the measurement can be realized when the measurement space is limited, and the safety risk can be reduced.

[0035] The technical solutions of the multimeter measurement auxiliary support provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0036] Referring to Figure 1 The multimeter measurement auxiliary support provided by the embodiments of the present application comprises two support units 100 and a connecting assembly 200. Each support unit 100 comprises a cylinder 110 and a protection strip 120 movably mounted in the cylinder 110. A fixing member 130 is arranged on the outer wall of the cylinder 110, and the fixing member 130 is configured to fix the electrodes of the multimeter on the cylinder 110. The protection strip 120 can move between a first position and a second position. The two ends of the connecting assembly 200 are connected with the two cylinders 110, respectively. After the electrodes are connected with the support unit 100, the contacts of the electrodes exceed the end of the cylinder 110. When the protection strip 120 is located at the first position, the first end of the protection strip 120 exceeds the contacts. When the protection strip 120 is located at the second position, the contacts exceed the first end of the protection strip 120.

[0037] Illustratively, the barrels 110 of the two support units 100 are arranged parallel to each other, and the cross-sectional shape of the barrel 110 can be square, circular or other suitable shape, which is not limited herein. The axis of the protective strip 120 is parallel to the axis of the barrel 110, and the protective strip 120 can be made of insulating material and will not conduct electricity when it contacts the charged equipment or other measurement points.

[0038] Optionally, the fixing member 130 can be fixed to the outer wall of the barrel 110 by bonding or clamping connection, etc. When the probe of the multimeter is fixed to the barrel 110 through the fixing member 130, the axis of the probe is parallel to the axis of the barrel 110.

[0039] It is worth mentioning that the protective strip 120 can move along the axial direction of the barrel 110 between the first position and the second position. Optionally, when the protective strip 120 is located at the second position, the first end of the protective strip 120 can be retracted to the inside of the barrel 110. During the connection of the probe and the barrel 110 of the corresponding support unit 100, the protective strip 120 can be moved to the first position, and the probe is ensured to exceed the end of the barrel 110 during installation, and the first end of the protective strip 120 exceeds the contact of the probe. In this way, it can be ensured that the first end of the protective strip 120 exceeds the contact when the protective strip 120 is located at the first position, and the contact exceeds the first end of the protective strip 120 when the protective strip 120 is located at the second position.

[0040] Illustratively, the connecting assembly 200 can be a strip structure, and the two ends of the strip structure are connected to the barrels 110 of the two support units 100, respectively. The end of the connecting assembly 200 can be fixed to the barrel 110 by bonding, welding or threaded connection, etc., which is not limited herein. Optionally, the connecting assembly 200 is arranged close to the top end of the barrel 110. The worker can hold the connecting assembly 200 with both hands, and when the measurement space is limited, the worker can also hold the connecting assembly 200 with one hand to complete the measurement.

[0041] The utility meter measurement auxiliary support provided by the embodiment comprises two support units 100 and a connecting assembly 200. Each support unit 100 comprises a cylinder 110 and a protective strip 120 movably mounted in the cylinder 110, and a fixing member 130 is arranged on the outer side wall of the cylinder 110. The protective strip 120 can move between a first position and a second position. The two ends of the connecting assembly 200 are connected to the two cylinders 110 respectively. When the utility meter needs to be used for measurement, the positive and negative probes of the utility meter can be fixed on the cylinders 110 of the two support units 100 through the fixing members 130. The staff can hold the connecting assembly 200 to extend the positive and negative probes to the position to be measured. In this process, the protective strip 120 is located at the first position, so as to avoid the contacts of the positive and negative probes from contacting other measurement points. When the positive and negative probes move to the preset position, the staff can adjust the protective strip 120 to move from the first position to the second position, so as to make the contacts of the positive and negative probes contact two measurement points to be measured respectively. In this way, when the measurement space is limited, the staff does not need to extend the hand to the position to be measured, and the utility meter can be normally used for measurement while the safety risk is reduced.

[0042] In one embodiment, as shown in Figure 1 and Figure 2 The connecting assembly 200 comprises a first pipe 210 and a second pipe 220. The first pipe 210 is connected to one of the cylinders 110, and the second pipe 220 is connected to the other cylinder 110. The end of the first pipe 210 extends into the interior of the second pipe 220 and is slidably connected to the second pipe 220.

[0043] The cross-sectional shape of the first pipe 210 matches the cross-sectional shape of the second pipe 220. The cross-sectional shape of the first pipe 210 and the second pipe 220 can be square or circular, which is not limited in this embodiment. In one possible implementation, the first pipe 210 and the second pipe 220 are both circular pipes. The side wall of each cylinder 110 is provided with an internally threaded hole. The end of the first pipe 210 and the end of the second pipe 220 are both provided with external threads. The end of the first pipe 210 extends into the internally threaded hole of one of the cylinders 110 and is threadedly connected to the internally threaded hole. The end of the second pipe 220 extends into the internally threaded hole of the other cylinder 110 and is threadedly connected to the internally threaded hole. It can be understood that the first pipe 210 is connected to the corresponding cylinder 110, and the other end of the first pipe 210 extends into the interior of the second pipe 220 and is slidably connected to the second pipe 220.

[0044] In this structure, the staff can adjust the length of the connecting assembly 200 by adjusting the length of the first pipe 210 extending into the second pipe 220, so as to adjust the distance between the two support units 100 according to the distance between the two measurement points to be measured, thereby improving the versatility of the utility meter measurement auxiliary support.

[0045] In one specific embodiment, as shown in Figure 1 and Figure 2 The connecting assembly 200 further comprises a first locking member 230. The first locking member 230 penetrates the second pipe body 220 and abuts against the first pipe body 210.

[0046] Illustratively, the first locking member 230 comprises a screw rod and a knob fixed at the end of the screw rod. The side wall of the second pipe body 220 is provided with an internally threaded hole, and the screw rod of the first locking member 230 penetrates the internally threaded hole and is threadedly connected with the internally threaded hole. The staff can make the first locking member 230 move along the axial direction of the internally threaded hole by rotating the knob. When it is necessary to adjust the length of the connecting assembly 200, the staff can rotate the knob to make the first locking member 230 disengage from the first pipe body 210, adjust the length of the first pipe body 210 extending into the second pipe body 220 to adjust the connecting assembly 200 to a preset length, and after adjusting the length of the connecting assembly 200, reverse rotate the knob to fix the first pipe body 210 and the second pipe body 220, thereby fixing the length of the connecting assembly 200.

[0047] Through the above arrangement, the first locking member 230 can be used to fix the first pipe body 210 and the second pipe body 220, thereby fixing the length of the connecting assembly 200, avoiding the distance between the two probes of the multimeter changing during the measurement process, and ensuring that reliable measurement can be performed using the multimeter.

[0048] In one specific embodiment, as shown in Figure 1 The number of connecting assemblies 200 is multiple, and the multiple connecting assemblies 200 are arranged at intervals along the axial direction of the cylinder body 110.

[0049] Illustratively, as shown in Figure 1 The number of connecting assemblies 200 can be two, and the two connecting assemblies 200 have an interval in the axial direction of the cylinder body 110. In other embodiments, the number of connecting assemblies 200 can also be three or four, etc. Those skilled in the art can set the specific number of connecting assemblies 200 and the distance between the two connecting assemblies 200 according to the needs, which is not limited herein.

[0050] In this embodiment, the number of connecting assemblies 200 is set to multiple, and the structural strength of the multimeter measurement auxiliary support can be improved by the multiple connecting assemblies 200, and the multimeter measurement auxiliary support is not easy to deform during the measurement process using the multimeter.

[0051] In one embodiment, as shown in Figure 1As shown, the support unit 100 further comprises an elastic member 140 and a locking mechanism 150, both of which are located inside the barrel 110. The elastic member 140 is sleeved on the protective strip 120, one end of the elastic member 140 abuts against the protective strip 120, and the other end abuts against the inner wall of the barrel 110. The locking mechanism 150 abuts against the second end of the protective strip 120, and the cap 160 is connected to one end of the locking mechanism 150 away from the second end.

[0052] Illustratively, the protective strip 120 is provided with a first limiting portion near the first end, and the end of the barrel 110 is provided with a second limiting portion inwardly, and the first end of the protective strip 120 can pass through the second limiting portion. After the elastic member 140 is sleeved on the protective strip 120, one end of the elastic member 140 abuts against the first limiting portion, and the other end abuts against the second limiting portion.

[0053] It can be understood that the elastic force of the elastic member 140 can drive the second end of the protective strip 120 to abut against the locking mechanism 150, and the locking mechanism 150 and the cap 160 can be made of insulating materials respectively, and when the staff presses the cap 160, the cap 160 can drive the locking mechanism 150 and the protective strip 120 to move relative to the barrel 110.

[0054] Among them, the locking mechanism 150 is widely used in ballpoint pens, and when the staff presses the cap 160 once, the protective strip 120 can move from the second position to the first position; and when the staff presses the cap 160 again, the protective strip 120 returns from the first position to the second position. The specific structure of the locking mechanism 150 in this embodiment is not limited, and those skilled in the art can select a suitable locking mechanism 150 according to actual needs.

[0055] Through the above setting, the staff can easily adjust the position of the protective strip 120, which is convenient for the operation of the multimeter measuring auxiliary support.

[0056] In one embodiment, as Figure 3 shown, the support unit 100 further comprises a second locking member 170. The protective strip 120 is in sliding connection with the barrel 110, the second end of the protective strip 120 extends out of the barrel 110, and the second locking member 170 penetrates through the barrel 110 and abuts against the protective strip 120.

[0057] The length of the protection strip 120 is greater than the length of the barrel 110, and the second end of the protection strip 120 held by the worker and the barrel 110 can adjust the position of the protection strip 120 relative to the barrel 110. Optionally, an inner threaded hole is formed in the side wall of the barrel 110, and the second locking member 170 passes through the inner threaded hole and is threadedly connected with the inner threaded hole. When the protection strip 120 moves to the preset position relative to the barrel 110, the protection strip 120 can be locked on the barrel 110 by rotating the second locking member 170 so that the second locking member 170 abuts against the side wall of the protection strip 120.

[0058] In this structure, the worker can adjust the position of the protection strip 120 relative to the barrel 110 as needed, and the position of the protection strip 120 can be fixed by the second locking member 170 after the protection strip 120 is adjusted to the preset position.

[0059] Optionally, the fixing member 130 includes two buckles arranged at intervals, and the interval between the two buckles is configured to allow the probe to extend into.

[0060] Illustratively, each buckle can be made of plastic, and the buckle can be fixed on the barrel 110 by adhesion, clamping connection, fastening by fasteners, or the like. It can be understood that when the probe of the multimeter extends between the two buckles, the two buckles can flexibly clamp the probe outside the barrel 110.

[0061] In this embodiment, two buckles are used as the fixing member 130, and the probe of the multimeter can be quickly installed on the barrel 110, which is convenient for the worker to use the multimeter and the multimeter measurement auxiliary support for measurement.

[0062] In a specific embodiment, the number of fixing members 130 is multiple, and the multiple fixing members 130 are arranged at intervals along the axial direction of the barrel 110.

[0063] The specific number of fixing members 130 in this embodiment is not limited, and a person skilled in the art can set it as needed, for example, three or four, etc. The number of fixing members 130 on the two barrels 110 can be the same or different, which is not uniquely limited herein.

[0064] In this structure, the probe of the multimeter is fixed on the barrel 110 by the multiple fixing members 130, which can improve the reliability of the connection between the probe and the corresponding barrel 110, and is conducive to assisting the multimeter in measurement by the multimeter measurement auxiliary support.

[0065] In a possible implementation, as Figure 4As shown, the fixing member 130 comprises a sleeve 131 and a third locking member 132. The sleeve 131 is coaxial with the axis of the barrel 110 and is configured to pass the probe. The third locking member 132 passes through the side wall of the sleeve 131 and is threadedly connected with the sleeve 131, and is configured to abut against the probe.

[0066] For example, the sleeve 131 can be fixed to the outer side wall of the barrel 110 by welding or clamping connection, which is not limited herein. It can be understood that the probe of the multimeter passes through the sleeve 131 and is coaxial with the sleeve 131. An internally threaded hole can be formed in the side wall of the sleeve 131, and the axis of the internally threaded hole is perpendicular to the axis of the sleeve 131. The third locking member 132 passes through the internally threaded hole of the sleeve 131 and is threadedly connected with the internally threaded hole. After the probe of the multimeter passes through the sleeve 131, the probe can be fixed to the sleeve 131 by rotating the third locking member 132 to abut against the probe.

[0067] In this structure, the probe can be fixed to the sleeve 131 by the third locking member 132, so as to fix the probe to the sleeve 131.

[0068] For example, the barrel 110 and the components of the connecting assembly 200 are provided with an insulating layer.

[0069] Optionally, after the barrel 110 is connected with the connecting assembly 200, an insulating layer can be coated on the outer side wall and the end wall of the barrel 110. For example, an insulating layer can be provided on each component of the connecting assembly 200.

[0070] Through the above arrangement, the barrel 110 and the connecting assembly 200 are insulated, so as to avoid the barrel 110 and the connecting assembly 200 from conducting electricity during the measurement by using the auxiliary measurement support of the multimeter, and ensure the safety of the measurement.

[0071] In other embodiments, the barrel 110 and the components of the connecting assembly 200 can be made of insulating materials, so as to ensure the safety of the measurement.

[0072] The operation process of the auxiliary measurement support of the multimeter provided in the embodiments of the present application is briefly introduced below, so that those skilled in the art can better understand the technical solutions of the present application.

[0073] When the measurement needs to be made by the multimeter, the length of the connecting assembly 200 is adjusted according to the distance between the two measurement points, and then the distance between the two support units 100 is adjusted. Specifically, the length of the first pipe body 210 extending into the second pipe body 220 is adjusted to adjust the length of the connecting assembly 200, and after the adjustment, the first locking member 230 is rotated to fix the length of the connecting assembly 200. The positive and negative probes of the multimeter are fixed on the barrel 110 by the fixing member 130 on the barrel 110.

[0074] When the measurement space is small, the worker can hold the connecting assembly 200 to extend the probes on the two support units 100 to the positions to be measured, and in this process, the protective strip 120 is located at the first position to avoid the contacts of the positive and negative probes from contacting other measurement points. When the positive and negative probes move to the preset positions, the worker can adjust the protective strip 120 to move from the first position to the second position, and then the contacts of the positive and negative probes are respectively contacted with the two measurement points to be measured to complete the measurement.

[0075] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
