[0025] EMBODIMENT

[0026] I. It is inconvenient to store and needs special support frame

[0027] Because the outer wall of the bridge plug is designed as a smooth circumference, the surface lacks stable support points, so that the bridge plug cannot be directly and stably placed on ordinary planes or conventional storage equipment. In order to solve this problem, a special support storage rack must be provided to fix the bridge plug, which not only increases the additional equipment cost, but also occupies more storage space, reduces the storage and transportation efficiency.

[0028] II. Cannot realize stacked storage

[0029] The circumferential outer wall design of the existing bridge plug makes it impossible to realize stable stacking between multiple bridge plugs. Because the outer wall is smooth and lacks anti-skid or positioning structure, sliding or toppling may occur during stacking, which poses a safety hazard and also limits the utilization rate of storage space. This design defect makes the bridge plug need more space and more complex fixing measures during storage and transportation, further increasing the operation cost.

[0030] Therefore, please refer to Figures 1-4This utility model provides a lightweight metal fast drilling bridge plug, including: a bridge plug body 1, and two sets of support stacking members 2 installed at the bottom of the bridge plug body 1. The two sets of support stacking members 2 are used to assist the bridge plug body 1 in being stably supported on the ground, and are also used to stack multiple bridge plug bodies 1.

[0031] Among them, the main body 1 of the bridge plug is made of lightweight and high-strength metal material, specifically magnesium alloy, which makes the fast-drilling bridge plug easier to drill while maintaining its strength. Magnesium alloy, as a lightweight and high-strength metal material, has significant advantages in bridge plug manufacturing.

[0032] Lightweight: Magnesium alloys have a low density, approximately 1.74 g / cm³. 3 It is significantly lower than that of steel and aluminum alloys, which can significantly reduce the overall weight of bridge plugs.

[0033] Easy to handle: The lightweight design makes the bridge plug easier to transport, install and remove, reducing the labor intensity of operators.

[0034] Further as Figures 1-4 As shown, it is worth noting that in order to ensure that the bridge plug body 1 can be stably placed on a normal plane or conventional storage equipment, and to achieve vertical stacking, each set of support stacking components 2 includes two symmetrically arranged embedded grooves 22 opened inside the bridge plug body 1. The two embedded grooves 22 are distributed in a figure-eight shape, and a support block 21 slides in each of the two embedded grooves 22. The top of each support block 21 is fixed to the inner top wall of the embedded groove 22 by a first spring 23. Each of the two support blocks 21 has an opening on one side wall. The device has a first slot 24 and a second slot 25 distributed vertically. The first slot 24 is located above the second slot 25. The vertical cross-sections of both the first slot 24 and the second slot 25 are I-shaped. A locking block 26 is engaged in the first slot 24. The vertical cross-section of the locking block 26 is also I-shaped. The locking block 26 is slidably connected to a groove on the outer wall of the bridge plug body 1. One end of the locking block 26 away from the first slot 24 is fixed to the inner wall of the groove by a second spring 27. A hand-holding groove 28 is provided on the outer side of the locking block 26 for finger insertion.

[0035] The design of the second slot 25 allows the support block 21 to be manually compressed back into the inner groove 22 when not in use, and is secured in the second slot 25 by one end of the locking block 26, thus fixing the support block 21 and preventing the support block 21 from protruding and affecting the use of the bridge plug body 1. The hand-operated groove 28 facilitates the manual pulling of the locking block 26.

[0036] In summary: when the light metal fast drilling bridge plug is used, when the bridge plug body 1 needs to be supported and stabilized, the two support blocks 21 respectively arranged in the two groups of support stacks 2 are pushed out from the inner embedding groove 22 by the first spring 23, and one end of the clamping block 26 is clamped in the first clamping groove 24 opened on the outer wall of the support block 21 by the action of the second spring 27, so that the four support blocks 21 are fixed, so that the bridge plug has a stable support point, and the bridge plug can be directly and smoothly placed on a common plane or a conventional storage device, in addition, the vertical stacking of multiple bridge plug bodies 1 can be realized, the storage space is effectively utilized, and at the same time, more space and more complex fixing measures are required during storage and transportation of the bridge plug, further reducing the operation cost.
