Description

Technical Field

[0001] The present application relates to the field of mechanical equipment, specifically to gas pipeline equipment, and more particularly to a gas buried valve key. Background Art

[0002] The switch on a PE underground gas valve is square. After installation, a corresponding operating pipe is left in the ground. To operate the valve, insert the valve key into the pipe and rotate the square switch to open or close the valve. Different PE valve sizes have different square switches, corresponding to different sized square keys. Traditional valve keys are often large, and carrying multiple valve keys takes up a lot of space, affecting efficiency. Furthermore, a valve key typically only works with one valve type, making it inconvenient for emergency personnel who are highly mobile, such as those riding electric scooters, to carry multiple valve keys. Summary of the Invention

[0003] The purpose of this application is to propose a more portable PE gas buried valve key. One key can be adapted to valves of various specifications. No additional auxiliary tools are required to achieve specification adaptation. The length is retractable and the handle can be detached and used flexibly, solving the technical problems mentioned in the above background technology section.

[0004] The present application provides a portable, adjustable PE gas buried valve key comprising a sleeve assembly, a diagonal plate key assembly, and a handle portion. Specifically, the sleeve assembly comprises a top sleeve, a bottom sleeve, and a stop assembly. The stop assembly is mounted on top of the bottom sleeve, and the bottom sleeve and the top sleeve are nested together to form a device that can be extended and retracted relative to each other in the longitudinal direction. The stop assembly secures the position of the two adjacent sleeves. The handle portion comprises a first handle and a second handle. The first and second handles are mounted on the top sleeve via T-slots or dovetail grooves. When the key is in use, the handles are mounted on the horizontal T-shaped boss at the top of the top sleeve. When the key is stored, the handles are mounted on the T-shaped bosses on both sides of the top sleeve. The diagonal plate key assembly comprises a right-angle plate, a connecting assembly, and a locking block. The right-angle plate and locking block are connected to the long plate of the bottom sleeve via the connecting assembly. The right-angle plate is located below the long plate of the bottom sleeve, and the locking block is located above the long plate. The two right-angle plates, mounted in a straight line, form the two diagonal corners of a square, corresponding to the two diagonal corners of the square switch of the buried valve. The size of the square is adjusted by radially moving the two right-angle plates. The locking block is provided with a 180-degree circular array of slots to limit the displacement and movement of the two diagonal plate assemblies. BRIEF DESCRIPTION OF THE DRAWINGS

The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0026] The key of the PE gas buried valve is a very critical component. Due to different specifications, higher requirements are placed on its portability and adaptability during maintenance and emergency. Figure 1 , This figure is a structural diagram of the PE gas buried valve key in one embodiment of the present application. Figure 1 As shown, the PE valve key includes a sleeve assembly 10, a diagonal plate key assembly 20, and a handle portion 30. The sleeve assembly 10 includes a top sleeve 11, a bottom sleeve 12, and a stopper 13. The diagonal plate key assembly 20 includes a first diagonal plate 21, a second diagonal plate 22, a connecting assembly 23, and a locking block 24. The handle portion 30 includes a first handle 31 and a second handle 32.

[0027] Continue to refer Figure 2 , which is a schematic structural diagram of the top sleeve 11 in one embodiment of the present application. Figure 2As shown, the top sleeve is a hollow tube with a handle mounting structure 11a at one end, including a rectangular plate 11b with a T-shaped boss 11c on the upper side, two T-shaped bosses 11d and 11e on the vertical sides, and corresponding T-slots on the two handles. When the key is needed, the two handles are mounted on the two ends of the T-shaped boss 11c to keep them horizontal. When the key is needed, the two handles are mounted on the T-shaped bosses 11d and 11e on both sides. There is a through hole 11f near the edge of the other end of the top sleeve 11, which runs through both sides of the top sleeve 11. When the limit device 13 at the top of the bottom sleeve 12 slides to the hole, the spring built into the limit device 13 will push the cap out, thereby limiting the relative position of the top sleeve 11 and the bottom sleeve 12.

[0028] Continue to refer Figure 3 This figure is a schematic diagram of the structure of the bottom sleeve 12 in one embodiment of the present application. As shown, a through hole 12a is provided near the top edge of the bottom sleeve 12. The cap of the retaining device 13 is installed here, ensuring a relatively stable connection between the retaining device 13 and the bottom sleeve 12. The bottom end of the bottom sleeve 12 has an elongated plate 12b. The lower surface of the long plate 12b has a T-shaped groove 12c for mounting the diagonal plate key assembly 20. The middle position of the long plate 12b has two oblong holes 12d and 12e on the left and right, respectively, which are used to limit the connection with the connecting assembly 22 of the diagonal plate key assembly 20 and adjust the size of the square key.

[0029] Continuing to refer to Figure 4, Figure 4A 1 is a schematic structural diagram of the position limiting assembly 13 in one embodiment of the present application. Figure 4B is a schematic cross-sectional view of the limiting component 13, Figure 4C is a structural diagram of the first connecting member 131, Figure 4D Schematic diagram of the structure of the second connecting member 132. Figure 4A 、 Figure 4B As shown, the limiting assembly 13 includes a first connecting member 131, a second connecting member 132, a first clamping cap 133, a second clamping cap 134 and a spring 135. Figure 4C As shown, the first connecting member 131 comprises a base plate 131a, a large side guard plate 131b, a small side guard plate 131c, an intermediate support plate 131d and a cylinder 131e. The outer diameter of the base plate 131a is smaller than or equal to the inner diameter of the top sleeve 11. A spring 135 is placed in the middle of the cylinder 131e, and a first clamping cap 133 and a second clamping cap 134 are placed at both ends. Figure 4DAs shown, the second connector 132 comprises a base 132a, a large side guard plate 132b, and a small side guard plate 132c. The outer diameter of the base 132a is the same as that of the large side guard plates 131b and the small side guard plate 131c of the first connector 131, and is smaller than the inner diameter of the bottom sleeve 12. Simultaneously pressing the first and second retaining caps 133 and 134 compresses the spring 135, causing the stop assembly 13 to slide into the bottom sleeve 12. When the first and second retaining caps 133 and 134 engage the through-hole 12a of the bottom sleeve 12, the stop assembly 13 is securely installed. The bottom sleeve 12 of the top limit assembly 13 is fitted onto the top sleeve 11, and the bottom sleeve 12 is slid back and forth to extend and shorten the entire buried valve key. When the first and second clamping caps 133, 134 are aligned with the through-hole 11f on the top sleeve 11, the spring 135 extends, pushing the first and second clamping caps 133, 134 out of the through-hole 11f. The two clamping caps restrict the relative position of the bottom sleeve 12 and the top sleeve 11. When the key needs to be stored, the first and second clamping caps 133, 134 can be pressed inward simultaneously, compressing the spring 135, and the clamping caps enter the top sleeve 11, eliminating the limiting effect. The bottom sleeve 12 can then slide into the top sleeve 11, shortening the overall length of the valve key for easier storage.

[0030] Continue to refer Figure 5 , Figure 5 This is a schematic structural diagram of the first diagonal plate 21 in one embodiment of the present application. Figure 5 As shown, the main body of the first diagonal plate 21 is a vertical angle plate 21a, with an end cap 21b at one end. End cap 21b has a T-shaped boss 21c that mates with the T-slot 12c of the bottom sleeve 12. A countersunk through-hole 21d is defined between the diagonal point of end cap 21b and the perpendicular line of the triangular side. This through-hole mates with the connecting assembly 23. In this embodiment, the structure of the second diagonal plate 22 is identical to that of the first diagonal plate 21, and the mounting positions are symmetrical, so further description is omitted.

[0031] Continue to refer Figure 6 , Figure 6 This is a schematic diagram of the structure of the connection component 23 in one embodiment of the present application. Figure 6 As shown, the connecting assembly 23 includes a bolt 231 and a nut 232, whose first function is to sequentially connect the first diagonal plate 21 (or the first diagonal plate 22), the long plate 12b of the bottom end sleeve 12, and the locking block 24; its second function is to limit the movement of the first diagonal plate 21 (or the first diagonal plate 22) so that its range of movement is confined to the oblong hole 12d or 12e; its third function is to lock the first diagonal plate 21 (or the first diagonal plate 22) together with the locking block 24.

[0032] Continue to refer Figure 7 , which is a schematic structural diagram of the locking block 24 in one embodiment of the present application. Figure 7As shown, the locking block 24 has a central circular through-hole 24a, which can be inserted through the bottom sleeve 12 and placed on the long plate 12b. Surrounding circular through-hole 24a are two concentric locking grooves: a first locking groove 24b and a second locking groove 24c. The first locking groove 24b consists of two circular arc grooves 24d and 24e of different radii. A radial groove 24f connects the two arc grooves 24d and 24e at one end. The widths of the arc grooves 24d, 24e, and 24f are greater than the diameter of the bolt 231, allowing the bolt 231 to move freely within the grooves. The second locking groove 24c forms a 180-degree circular array with the first locking groove 24b and will not be further described here.

[0033] Continuing to refer to Figure 8, Figure 8A FIG. 2 is a partial structural diagram of a locking block 24 locking a diagonal plate key assembly 20 in an embodiment of the present application. Figure 8A As shown, the first diagonal plate 21 is moved into the arc groove 24d of the locking groove 24b, and the second diagonal plate 22 is moved into the arc groove of the same diameter in the locking groove 24c. Then, the locking block 24 is rotated so that the semicircular portion of the arc groove 24d contacts the bolt 231 to lock its movement. When the size of the diagonal plate key assembly needs to be adjusted, the locking block 24 can be rotated in the opposite direction so that the radial groove 24f on the locking block 24 is parallel to the oblong hole 12d on the bottom end sleeve 12, as shown in FIG. Figure 8B The bolt 231 can move along the oblong hole 12d into the arc groove 24e, thereby changing the distance between the two diagonal plates.

[0034] Continue to refer Figure 9 , which is a schematic diagram of the structure of the first handle 31 in one embodiment of the present application. Figure 9 As shown, one end of the first handle 31 has a T-slot 31a, which is located a certain distance from the other end of the first handle. In this embodiment, the second handle 32 has the same structure as the first handle 31, and the mounting positions are symmetrical, so further description is omitted. When the handles are in use, the T-slots of the first and second handles 31, 32 are respectively mounted on the ends of the horizontal T-shaped boss 11c of the top sleeve 11, with the two handles in a horizontal position. When the handles are stored, the first and second handles 31, 32 are respectively mounted on the two T-shaped bosses 11d and 11e on the sides of the top sleeve 11, making them easier to carry.

[0035] Replay Figure 1This figure shows the overall assembly of a portable, adjustable PE gas buried valve key. In this embodiment, the first and second handles 31, 32 have T-slots that connect to the T-shaped bosses on the top sleeve 11. When stored, the T-slots of the two handles mate with the T-shaped bosses 11d and 11e on the sides of the top sleeve 11. When the handles are needed to rotate the valve key, the two handles are mounted on both ends of the horizontal T-shaped boss 11c on the top sleeve 11 for convenient use. The top sleeve 11 and the bottom sleeve 12 can be nested together, and the two sleeves can move relative to each other to adjust the length of the key. A limiter 13 is installed at the top of the bottom sleeve 12. When the limiter 13 reaches the circular hole 11f of the top sleeve 11 during relative displacement between the top and bottom sleeves 11, the first and second retaining caps 133, 134 on either side of the limiter 13 automatically pop out under the thrust of the intermediate spring 135, locking into the circular hole 11f and thus limiting the displacement of the two sleeves. When storing, the first and second caps 133 and 134 are pressed simultaneously, causing the spring 135 in the middle to contract and the caps to enter the top sleeve 11. The restriction between the top sleeve 11 and the bottom sleeve 12 is released, allowing the bottom sleeve 12 to be pushed into the top sleeve 11, thereby shortening the PE gas buried valve key as a whole, making it easier to carry and store. In this embodiment, the portion corresponding to the square switch of the PE gas buried valve is the key diagonal plate key assembly 20. Its first diagonal plate 21 and second diagonal plate 22 form two right angles on the diagonal of a square, which can accommodate the square switch of the PE gas buried valve. Rotating the horizontally mounted handle component 30 causes the first diagonal plate 21 and second diagonal plate 22 to rotate the square switch, thereby opening and closing the PE gas buried valve. In this embodiment, the diagonal plate key assembly is designed to be adjustable in size. Its locking block 24 includes two locking grooves 24b and 24c arranged in a 180-degree circular array. These two locking grooves are composed of arc grooves of different diameters and radial grooves extending through the arc grooves. By rotating the locking block 24 until the long side of the radial groove is parallel to the long side of the oblong hole 12d, the first diagonal plate 21 and the second diagonal plate 22 can be moved within the grooves to change the diagonal dimensions. After the first and second diagonal plates 21, 22 are adjusted to the desired positions, the locking block 24 is rotated again so that the semicircular surfaces of the arc grooves contact the bolts 231 of the connecting assembly 23, thereby locking the relative positions of the first and second diagonal plates 21, 22.

[0036] In the previous embodiment, the sleeve assembly 10 includes a top sleeve 11, a bottom sleeve 12 and a limiting device 13. In this embodiment, the sleeve assembly 10 includes a top sleeve 11, an intermediate sleeve 14, a bottom sleeve 12, a limiting device 13 and a second limiting device 15. Figure 10 , which is another embodiment of the present application. Figure 10As shown, the intermediate sleeve 14 is also a hollow sleeve with a limit hole 14a near the bottom end and a limit device 15 installed at the top end. The structure and composition of the limit device 15 are the same as those of the limit device 13, differing only in size. The outer diameter of the intermediate sleeve 14 is smaller than the inner diameter of the top sleeve 11, and the inner diameter of the intermediate sleeve 14 is larger than the outer diameter of the bottom sleeve 12. The top sleeve 11, the intermediate sleeve 14, and the bottom sleeve 12 can be sequentially inserted and positioned using the limit device. Compared to the previous embodiment, the addition of the intermediate sleeve 14 expands the telescopic range of the PE gas buried valve key, making it suitable for use in situations where the buried valve is far from the operating nozzle.

[0037] In other optional implementations of this embodiment, the number of the intermediate sleeves 14 and the corresponding limiting devices includes but is not limited to: 1, 2, or 3.

[0038] Continue to refer Figure 11 This figure shows another embodiment of the present application. In this case, the sleeve components are combined into a structural sleeve 16. Its top end has a handle mounting structure similar to the top sleeve 11, and its bottom end has a long plate structure similar to the bottom sleeve 12. This case is suitable for situations where the buried valve is close to the operating pipe opening.

[0039] Continue to refer Figure 12 , which is a schematic diagram of the structure of the locking block in another embodiment of the present application. Figure 12 As shown, the arcuate grooves in the locking block's locking slot limit the displacement of the diagonal plate and lock it. The number of arcuate grooves determines the adjustable specifications of the PE gas buried valve key. In the above embodiment, the locking slot includes two arcuate grooves, indicating that the key can open keys of two different specifications. In this embodiment, the locking block 25 has three arcuate grooves (25a, 25b, and 25c), allowing the key to open keys of three different specifications.

[0040] In other optional implementations of this embodiment, the number of arc grooves includes but is not limited to: 4, 5, and 6.

[0041] Continue to refer Figure 13 , this figure is a schematic diagram of the structure of a handle in another embodiment of the present application. Figure 14 As shown, one end face of the handle 33 has a dovetail groove 33a, and the corresponding top sleeve has a dovetail boss. The handle 33 is installed by a dovetail connection.

[0042] Continue to refer Figure 14 , this figure is a structural diagram of the diagonal plate in another embodiment of the present application. Figure 14 As shown, there is a dovetail boss 26a on the end cover at the top of the diagonal plate 26, and a dovetail groove is provided on the lower surface of the long plate of the corresponding bottom sleeve, and the installation is carried out through a dovetail connection.

[0043] The main concept of this application is to achieve a more portable and easy-to-use PE gas buried valve key through a removable and removable handle, a retractable sleeve, and an adjustable diagonal plate, providing a better tool for gas maintenance and emergency personnel. The handle is installed using a T-shaped boss or a dovetail boss; the overall key is retracted by sleeves of different diameters to form relative displacement and a limit device to limit the position; the key's key portion uses a diagonal plate to form a square to accommodate the square switch on the buried valve, and the use of a locking block with a locking groove allows the key specifications to be changed without the use of other tools.
