Each flexible clamping block includes an arc-shaped segment connected to the bottom of the movable plate and a protruding segment disposed on the arc-shaped segment. The side of the protruding segment that contacts the through hole is an inclined surface. When the tension spring is in its natural state, the clamping component is located at the top of the partition plate. The locking assembly also includes a pushing component for pushing the movable plate downward. When the movable plate moves downward, the protruding section is inserted into the through hole and is restricted by the through hole to bend towards the guide rod until the arc-shaped section abuts against the guide rod.

[0008] Furthermore, the pushing component includes a pressing seat located on the top of the movable plate, a pressing rod extending through the handle is provided on the top of the pressing seat, a crossbar is provided on the top of the pressing rod, and an L-shaped limiting strip located within the rotation area of ​​the crossbar is provided on the top of the handle.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0015] Please see Figure 1-5 This utility model discloses a gas valve key, comprising: The key head 1 includes a pressing head 11 with an open bottom. A partition plate 12 is fixedly installed inside the pressing head 11. Multiple movable blocks 13 located at the bottom of the partition plate 12 are movably installed inside the pressing head 11. A guide rod 14 penetrating the partition plate 12 is provided on the top of each movable block 13. A compression spring 15 that is sleeved with the corresponding guide rod 14 is fixedly installed between each movable block 13 and the partition plate 12. The key head 1 also includes a locking component 16 for locking each guide rod 14 after the movable block 13 moves upward. Handle 2, located on top of key head 1, is for people to hold.

[0016] This utility model allows the operator to hold the handle 2, move the key head 1 above the valve core to be turned, and then press down the handle 2, so that the corresponding movable block 13 can rise according to the shape of the valve core. Thus, when turning it later, the other movable blocks 13 can drive the valve core to rotate. It can match various underground valve cores. After turning is completed, by removing the key head 1 from the valve core, each movable block 13 can be reset under the push of the compression spring 15 for the next use. Due to the setting of the locking component 16, the adjusted guide rod 14 can be locked, which can reduce the downward pressure required when turning, save more effort, and improve the efficiency of turning the same type of valve core.

[0017] In one embodiment, the locking assembly 16 includes a movable plate 161 movably disposed within the key head 1 and located at the top of the partition plate 12. When the compression spring 15 is in its natural state, the guide rod 14 passes through the movable plate 161. The partition plate 12 is provided with a through hole for the guide rod 14 to pass through. The diameter of the through hole is larger than the diameter of the guide rod 14. Multiple tension springs 162 are provided between the top of the movable plate 161 and the key head 1. Multiple clamping components 163 corresponding to each guide rod 14 are provided at the bottom of the movable plate 161. Each clamping component 163 is composed of multiple flexible clamping blocks arranged in a ring outside the corresponding guide rod 14. The flexible clamping block includes an arc-shaped segment connected to the bottom of the movable plate 161 and a protruding segment provided on the arc-shaped segment. The side of the protruding segment that contacts the through hole is an inclined surface. When the tension spring 162 is in its natural state, the clamping component 163 is located at the top of the partition plate 12. The locking assembly 16 also includes a pushing member for pushing the movable plate 161 downward. When the movable plate 161 moves downward, the protruding section is inserted into the through hole and is restricted by the through hole to bend toward the guide rod 14 until the arc-shaped section abuts against the guide rod 14.

[0018] With this design, each movable block 13 can move freely when the pushing component is not operated. When the pushing component pushes the movable plate 161 down, each flexible clamping block moves down and inserts into the corresponding through hole. Under the constraint of the through hole, it bends towards the guide rod 14 until the arc segment abuts against the guide rod 14. This prevents the guide rod 14 from moving further due to the friction of the multiple flexible clamping blocks, thereby locking the guide rod 14. When the pushing component releases the pressure on the movable plate 161, the movable plate 161 can move up and reset under the pull of the tension spring 162, releasing the flexible clamping blocks from restricting the guide rod 14.

[0019] In one embodiment, the pushing component includes a pressing seat 164 located on top of the movable plate 161. A pressing rod 165 passing through the handle 2 is provided on the top of the pressing seat 164. A crossbar 166 is provided on the top of the pressing rod 165. An L-shaped limiting strip 167 located in the rotation area of ​​the crossbar 166 is provided on the top of the handle 2. The L-shaped limiting strip 167 is composed of a vertical section connected to the handle 2 and a horizontal section connected to the vertical section. When the tension spring 162 is in its natural state, the top of the crossbar 166 is located above the bottom of the horizontal section. When the pressing rod 165 moves down to its limit position, the top of the crossbar 166 is flush with the bottom of the horizontal section.

[0020] This design allows the operator to operate the pusher component outside the pit of the buried valve by first pressing down the pressure rod 165 to the lower limit position and then rotating the crossbar 166 into the L-shaped limit bar 167. The L-shaped limit bar 167 prevents the pressure rod 165 from moving upward and resetting, thus improving the safety of operation. Furthermore, during the process of turning the valve core, there is no need to continuously apply downward pressure to the pressure rod 165.

[0021] In one embodiment, the handle 2 includes a fixed section 21 fixedly disposed on the top of the pressing head 11 and a detachable section 22 threadedly disposed on the top of the fixed section 21. The pressure rod 165 is composed of multiple tubular segments and corresponds to the fixed section 21 and the detachable section 22.

[0022] This design, by segmenting the handle 2 and the pressure bar 165, makes it easy to carry and transport.

[0023] In one embodiment, the handle 2 further includes at least one extension section 23, with both ends of the extension section 23 being threadedly connected to the fixed section 21 and the detachable section 22, respectively, and each extension section 23 is provided with a tube column.

[0024] This design allows the handle 2 to be extended in length by adding multiple extension sections 23 and corresponding tubing, thereby meeting the operational needs of valve wells at various depths.

[0025] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0026] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features.
