[0022] The beneficial effects of the utility model are:

[0023] The portable leakage detection bracket proposed by the present invention includes a clamping assembly, a support assembly and an adjustment assembly. The clamping assembly includes a clamp, a vertical pole and a fixed seat. One end of the vertical pole is connected to the clamp, and the other end of the vertical pole is connected to the fixed seat. The clamp is used to fix the leakage detector. The support assembly includes three groups of legs. The three groups of legs are evenly spaced along the circumference of the fixed seat. Each group of legs includes an upper leg, a lower leg and a pin. One end of the upper leg is rotatably connected to the fixed seat, and the other end of the upper leg can be rotatably connected to the first end of the lower leg or inserted into the cavity of the lower leg. The pin is made of conductive material, and the pin is insulated and connected to the second end of the lower leg. The first end of the pin is inserted into the cavity of the lower leg and connected to a cable. The cable is used to connect to the leakage detector, and the second end of the pin is used to be inserted into the ground. In a specific implementation, one end of the cable is connected to a conductive pin, and the other end of the cable passes through the lower leg, upper leg, and the interior of the column and extends to the clamp. The other end of the cable is connected to a leakage detector fixed on the clamp, thereby realizing leakage detection of the contact position of the pin. The adjustment assembly includes an adjustment rod, a movable ring, and three pins. One end of the adjustment rod is connected to a fixed seat. The movable ring is movably mounted on the outer circumference of the adjustment rod. The three pins are evenly spaced along the circumference of the movable ring and are all rotatably connected to the movable ring. The ends of the three pins that are not connected to the movable ring are correspondingly rotatably connected to the three upper legs. In a specific implementation, because one end of the three pins is rotatably connected to the movable ring, when the movable ring moves along the axial direction of the adjustment rod, it will drive the pins to rotate around the adjustment rod, and cause the upper legs connected to the pins to rotate around the fixed seat to realize the expansion or contraction of the three upper legs. The three upper legs are expanded to ensure the stability of the support assembly. In the present invention, when the vertical pole is set vertically and the clamping assembly is located above the support assembly, as the movable ring moves upward, the other ends of the three upper legs that are not connected to the fixed base move away from each other, thereby forming the deployment of the three upper legs. Then, the lower leg is pulled along the extension direction of the upper leg to move the lower leg toward the side away from the upper leg. When the upper leg is separated from the cavity of the lower leg, the upper leg can rotate relative to the lower leg, and the length of the support assembly in the extension direction of the upper leg will become longer, which can meet actual detection needs. Finally, the pin is inserted into the ground so that the lower leg can be vertically fixed to the ground. The upper leg that is rotatably connected to each lower leg is restricted by the structure of the three upper legs being evenly spaced along the circumference of the fixed base. When the lower leg is fixed, the relative positions of the three upper legs will also be fixed, thereby achieving relative fixation of the support assembly and the ground, thereby ensuring the stability of the portable leakage detection bracket. After the test is completed, the pins can be pulled out from the ground, and the upper leg portion can be inserted into the cavity of the lower leg to complete the folding of the support assembly for easy carrying.The portable leakage detection bracket provided by the utility model is fixed to the ground by means of pins, so that the lower leg can be perpendicular to the ground instead of continuously extending along the extension direction of the upper leg. While ensuring the detection height of the portable leakage detection bracket, it can reduce the space occupied by the support component on the ground, ensure stability, and make its use scenarios more extensive.

Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0042] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0043] like Figures 1 to 4As shown, this embodiment provides a portable leakage detection bracket, including a clamping assembly, a support assembly and an adjustment assembly. The clamping assembly includes a clamp 1, a vertical pole 2 and a fixed base 3. One end of the vertical pole 2 is connected to the clamp 1, and the other end of the vertical pole 2 is connected to the fixed base 3. The clamp 1 is used to fix the leakage detector. The support assembly includes three groups of legs, and the three groups of legs are evenly spaced along the circumference of the fixed base 3. Each group of legs includes an upper leg 4, a lower leg 5 and a pin 6. One end of the upper leg 4 is rotatably connected to the fixed base 3, and the other end of the upper leg 4 can be rotatably connected to the first end of the lower leg 5 or inserted into the cavity of the lower leg 5. The pin 6 is made of a conductive material, and the pin 6 is insulated and connected to the second end of the lower leg 5. The first end of the pin 6 is inserted into the cavity of the lower leg 5 and connected to a cable. The cable is used to connect to the leakage detector, and the second end of the pin 6 is used to be inserted into the ground. During specific implementation, one end of the cable is connected to the conductive pin 6, and the other end of the cable passes through the lower leg 5, the upper leg 4 and the interior of the column and extends to the clamp 1, and the other end of the cable is connected to the leakage detector fixed on the clamp 1, so that leakage detection can be achieved for the contact position of the pin 6.

[0044] The adjustment assembly includes an adjustment rod 7, a movable ring 8, and three pins 9. One end of the adjustment rod 7 is connected to the fixed seat 3. The movable ring 8 is movably mounted on the outer circumference of the adjustment rod 7. The three pins 9 are evenly spaced along the circumference of the movable ring 8 and are all rotatably connected to the movable ring 8. The ends of the three pins 9 that are not connected to the movable ring 8 are rotatably connected to the three upper legs 4. In specific implementation, because one end of the three pins 9 is rotatably connected to the movable ring 8, when the movable ring 8 moves along the axial direction of the adjustment rod 7, it drives the pins 9 to rotate around the adjustment rod 7, and causes the upper legs 4 connected to the pins 9 to rotate around the fixed seat 3, thereby realizing the expansion or contraction of the three upper legs 4. The three upper legs 4 are expanded to ensure the stability of the support assembly.

[0045] In this embodiment, when the upright 2 is positioned vertically and the clamping assembly is positioned above the support assembly, as the movable ring 8 moves upward, the ends of the three upper legs 4 not connected to the fixed base 3 move away from each other, thereby deploying the three upper legs 4. Subsequently, the lower leg 5 is pulled along the extension direction of the upper leg 4 to move away from the upper leg 4. When the upper leg 4 is released from the cavity of the lower leg 5, the upper leg 4 can rotate relative to the lower leg 5, and the length of the support assembly in the extension direction of the upper leg 4 increases, meeting actual detection requirements. Finally, the pins 6 are inserted into the ground to vertically secure the lower leg 5 to the ground. The upper legs 4, which are rotatably connected to each lower leg 5, are constrained by the uniform spacing of the three upper legs 4 along the circumference of the fixed base 3. When the lower leg 5 is fixed, the relative positions of the three upper legs 4 are also fixed, thereby achieving relative fixation of the support assembly to the ground and ensuring the stability of the portable leakage detection stand. After the test is completed, the pin 6 can be pulled out from the ground, and the upper leg 4 is partially inserted into the cavity of the lower leg 5 to complete the folding of the support assembly for easy carrying.

[0046] The portable leakage detection bracket provided in this embodiment is fixed to the ground by means of the pin 6, so that the lower leg 5 can be perpendicular to the ground instead of continuously extending along the extension direction of the upper leg 4. While ensuring the detection height of the portable leakage detection bracket, it can reduce the space occupied by the support component on the ground, ensure stability, and make its use scenarios more extensive.

[0047] Alternatively, as Figure 3 As shown, the second end of the lower leg 5 is provided with a mounting hole, which is connected to the cavity of the lower leg 5. The first end of the pin 6 is inserted into the mounting hole and is threadedly connected to the lower leg 5. In a specific implementation, the first end of the pin 6 passes through the mounting hole and extends into the cavity. The cable is connected to the first end of the pin 6 and is located in the cavity of the lower leg 5. The outer periphery of the first end of the pin 6 is provided with an external thread, and the mounting hole is provided with an internal thread, so that the pin 6 and the lower leg 5 are threadedly connected. This not only facilitates the installation of the pin 6, but also allows the operator to adjust the depth of the three pins 6 inserted into the mounting holes according to the flatness of the bottom surface. The external thread provided on the outer periphery of the pin 6 has a preset length along the extension direction of the lower leg 5, so that the connection position of the pin 6 and the lower leg 5 can be adjusted by rotating the pin 6, that is, the depth of the pin 6 inserted into the mounting hole can be adjusted.

[0048] In this embodiment, a nylon sleeve with internal threads is installed in the mounting hole of the lower leg 5. The nylon sleeve serves as an insulator, ensuring insulated contact between the pin 6 and the lower leg 5. In other embodiments, an insulating layer may be provided on the inner surface of the lower leg 5 to ensure insulated contact between the pin 6 and the lower leg 5. In this embodiment, the pin 6 is made of copper, which has high electrical conductivity and excellent corrosion resistance, making it particularly suitable for use in humid environments or those containing corrosive substances. In this embodiment, the second end of the pin 6 has a tapered structure, which facilitates insertion into the ground.

[0049] Alternatively, as Figure 3 As shown, the support assembly also includes a locking nut, which is threaded onto pin 6 and located outside the cavity of lower leg 5. A nylon sleeve is disposed within the mounting hole. The first end of pin 6 is threadedly connected to the nylon sleeve, and the locking nut abuts the nylon sleeve. The locking nut prevents the threaded connection between pin 6 and the nylon sleeve from loosening under vibration conditions, ensuring a secure connection between pin 6 and lower leg 5. The locking nut abuts only the nylon sleeve, not the lower leg 5, in the direction of extension of the lower leg 5, ensuring insulated contact between pin 6 and the lower leg 5.

[0050] Further, if Figure 2As shown, the upper leg 4 includes a penetration portion 42 and a connecting portion 41. The connecting portion 41 is rotatably connected to the fixing seat 3. The penetration portion 42 can be rotatably connected to the first end of the lower leg 5 or penetrated into the cavity of the lower leg 5. A first elastic positioning pin 421 is provided on the penetration portion 42. The first elastic positioning pin 421 is located at the end of the penetration portion 42 close to the connecting portion 41. When the penetration portion 42 is penetrated into the cavity of the lower leg 5, the first elastic positioning pin 421 is used to define the position of the lower leg 5 in the extension direction of the penetration portion 42. A second elastic positioning pin 422 is also provided on the penetration portion 42. The second elastic positioning pin 422 is located at the end of the penetration portion 42 away from the connecting portion 41. When the penetration portion 42 is not penetrated into the cavity of the lower leg 5, the second elastic positioning pin 422 is used to define the position of the lower leg 5 in the extension direction of the penetration portion 42. In this embodiment, the first elastic locating pin 421 and the second elastic locating pin 422 have the same structure. The elastic locating pin includes a sleeve, an elastic member, and a connector. The connector can be rotatably arranged at the end of the sleeve and is partially located outside the sleeve. The elastic member is inserted into the sleeve, and one end of the elastic member in the compression direction is connected to the connector, and the other end is connected to the inner bottom wall of the sleeve. Pressing the connector can compress the elastic member and move the connector toward the inner bottom wall of the sleeve. A first hole is provided on the lower leg 5. When the insertion portion 42 is inserted into the cavity of the lower leg 5, the first elastic locating pin 421 can be opposite to the first hole, and the connector of the first elastic locating pin 421 can extend into the first hole, thereby defining the position of the lower leg 5 and the upper leg 4. A second hole is provided on the lower leg 5. When the penetration portion 42 is not inserted into the cavity of the lower leg 5, the second elastic positioning pin 422 can be opposite to the first hole, and the connector of the second elastic positioning pin 422 can be inserted into the second hole, thereby defining the position of the lower leg 5 and the upper leg 4. The structure of the elastic positioning pin is prior art and will not be described in detail here.

[0051] Alternatively, as Figure 2 As shown, the penetration portion 42 and the connecting portion 41 form a first step surface in the extension direction of the upper leg 4. When the penetration portion 42 is penetrated into the cavity of the lower leg 5, the first step surface can abut the first end of the lower leg 5, thereby limiting the position of the lower leg 5 in the penetration portion 42, making it convenient for the first elastic positioning pin 421 to be quickly aligned with the first hole.

[0052] Further, if Figure 3 As shown, the fixed base 3 is provided with a rotation hole, into which one end of the adjustment rod 7 can be rotatably inserted. The movable ring 8 is sleeved around the outer periphery of the adjustment rod 7 and threadedly connected to the adjustment rod 7. In this embodiment, the outer periphery of the adjustment rod 7 is provided with an external thread, while the inner ring of the movable ring 8 is provided with an internal thread. Rotating the adjustment rod 7 causes the movable ring 8 to move axially in the direction of the adjustment rod 7. A gap is provided between the outer periphery of the adjustment rod 7 and the inner wall of the rotation hole to reduce friction between the fixed base 3 and the adjustment rod 7, thereby preventing difficulty in rotating the adjustment rod 7.

[0053] Optionally, a handle 71 is provided at the other end of the adjusting rod 7 that is not connected to the fixing base 3. In this embodiment, the handle 71 is arranged around the outer circumference of the adjusting rod 7. The operator can hold the handle 71 to rotate the adjusting rod 7. The shape of the handle 71 is selected to facilitate the operator's grip, making it easier to rotate the adjusting rod 7.

[0054] Alternatively, as Figure 3 As shown, a retaining ring 72 is sleeved on one end of the adjusting rod 7. When the adjusting rod 7 is inserted into the rotating hole, the retaining ring 72 abuts against the end of the rotating hole facing away from the movable ring 8. In a specific embodiment, an annular groove is provided at one end of the adjusting rod 7. The retaining ring 72 can be an elastic retaining ring for a shaft. The retaining ring 72 is sleeved in the annular groove so that the retaining ring 72 protrudes radially from the outer circumference of the adjusting rod 7. When the adjusting rod 7 is inserted into the rotating hole and placed vertically, the abutment between the retaining ring 72 and the end of the rotating hole can prevent the adjusting rod 7 from being disengaged from the rotating hole due to gravity. In this embodiment, the rotating hole is a stepped hole, which includes a first hole and a second hole that are connected. The first hole is located above the second hole, and the diameter of the first hole is larger than the diameter of the second hole. When one end of the adjusting rod 7 is inserted into the rotating hole, the retaining ring 72 can be located in the first hole and will not protrude vertically from the fixing seat 3.

[0055] Alternatively, as Figure 3 As shown, one end of the adjusting rod 7 has a second stepped surface. When the adjusting rod 7 is inserted into the rotating hole, the second stepped surface abuts the other end of the rotating hole near the movable ring 8. In a specific implementation, due to the provision of the second stepped surface, one end of the adjusting rod 7 can be inserted into the rotating hole from the bottom of the fixing seat 3. The second stepped surface is used to limit the depth of penetration of the one end of the adjusting rod 7 into the rotating hole. After the one end of the adjusting rod 7 has penetrated into the rotating hole, the retaining ring 72 can be sleeved on the annular groove of the adjusting rod 7. The retaining ring 72 and the second stepped surface together limit the axial movement distance of the adjusting rod 7.

[0056] Furthermore, if Figure 2 As shown, the vertical pole 2 includes a fixed rod 21 and a movable rod 22. The fixed rod 21 has a fixed cavity 211. The first end of the fixed rod 21 is provided with an opening communicating with the fixed cavity 211. The first end of the movable rod 22 is movable through the opening and is disposed in the fixed cavity 211. The second end of the movable rod 22 is provided with a clamp 1, and the second end of the fixed rod 21 is connected to the fixing seat 3. The movable rod 22 can move relative to the fixed rod 21 to adjust the length of the vertical pole 2. That is, the height of the portable leakage detection bracket can be raised when in use. When not in use, the movable rod 22 can be retracted into the fixed cavity 211 to shorten the length of the vertical pole, making it easier to store and carry the portable leakage detection bracket.

[0057] Optionally, a locking sleeve 23 is provided at the opening. The locking sleeve 23 is sleeved over the first end of the fixed rod 21 and threadedly connected to the fixed rod 21. The movable rod 22 is inserted through the inner ring of the locking sleeve 23. The locking sleeve 23 is used to secure the movable rod 22 to the fixed rod 21. In practice, as the locking sleeve 23 rotates and moves toward the fixed movable rod 22, the locking sleeve 23 gradually deforms the opening of the fixed rod 21 until it locks the movable rod 22 inserted into the opening, thereby locking the fixed rod 21 and the movable rod 22 in position. The structure of the locking sleeve 23 is conventional and will not be described in detail here.

[0058] The above embodiments merely illustrate the basic principles and features of the present invention. The present invention is not limited to the above embodiments. Various changes and modifications are possible without departing from the spirit and scope of the present invention. Such changes and modifications are within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
