Description

Technical Field

[0001] This utility model relates to an impact-resistant pressure structure and a static level, belonging to the technical field of static level protective equipment. Background Technology

[0002] A hydrostatic level is a precision instrument for measuring elevation differences and their changes. It is widely used in dams, nuclear power plants, subways, tunnels, and other fields, and has advantages such as high measurement accuracy and strong stability.

[0003] Currently, at building construction sites, it is necessary to use hydrostatic level instruments to measure the uneven settlement of measurement points at different locations. Because falling objects often occur at construction sites, the hydrostatic level instrument needs to be protected after installation. The existing method for protecting the hydrostatic level instrument is to have workers install a protective shell on the outside of the instrument.

[0004] In current technology, the protection of a static level instrument is achieved by simply installing a protective shell on its exterior without taking other protective measures. However, the protective shell is easily damaged by impact and thus fails to provide protection, compromising the safety of the static level instrument. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an impact-resistant pressure structure and a static level.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0007] An impact-resistant structure and a static level include a protective box with a protective cavity. Angle plate guides are provided at the four corners inside the protective cavity. A static level body is installed between the four angle plate guides. The corner sides of the static level body, located between the angle plate guides and the inner wall of the protective cavity, are connected and fixed by connectors. The connectors confine the static level body within the protective cavity. A mounting cavity is provided on the top side of the protective box. A mounting plate is placed inside the mounting cavity. The top of the mounting plate is connected to several impact-resistant seats, which extend to the top of the protective box. The bottom sides of the mounting plate are respectively pressed against a set of support plates, which are laterally slidably connected inside the mounting cavity.

[0008] Furthermore, the connector includes a locking member, which is an L-shaped structure. Both ends of the L-shaped structure are provided with reinforcing flanges, and bolt holes are provided on the reinforcing flanges. The corner plate guide rail and the inner wall of the protective cavity are provided with a plurality of bolt grooves that mate with the bolt holes. The bolt grooves and the bolt holes are fixed together by bolts.

[0009] Furthermore, the impact-resistant seat includes a detachable housing, which is installed on the top of the mounting plate. A sliding plate is slidably connected inside the detachable housing. A damping spring is connected between the inner bottom of the detachable housing and the bottom of the sliding plate. A support column is connected to the top center of the sliding plate. The top end of the support column extends through to the top of the detachable housing and is fixedly connected to the load-bearing seat. The top end of the load-bearing seat extends through to the top of the protective box.

[0010] Furthermore, a connecting rod is fixed at the top center of the load-bearing seat. The top of the outer circumference of the connecting rod is provided with an external thread, and the bottom of the outer circumference of the connecting rod is provided with two sets of locking holes in a cross shape. The connecting rod is threaded into a threaded groove, which is located at the bottom center of the impact seat. The top of the impact seat is provided with an impact ramp, and each of the four ramps of the impact ramp is provided with a groove. The four grooves are arranged in a cross shape, and two sets of through holes that cooperate with the locking holes are also provided in the four grooves.

[0011] Furthermore, the impact-resistant seat also includes a snap-fit ​​seat and a snap-fit ​​block. The snap-fit ​​seat and the snap-fit ​​block are respectively located in two inclined grooves in the same direction. The top of the load-bearing seat is provided with a snap-fit ​​groove that mates with the snap-fit ​​block. A threaded rod is fixed to the middle of the side of the snap-fit ​​seat. The threaded rod connects and fixes the connecting rod and the impact seat through the through hole and the locking hole. A nut is connected to the threaded end of the threaded rod, which is located outside the snap-fit ​​block.

[0012] Furthermore, the detachable housing includes a movable top shell and a fixed bottom shell, the fixed bottom shell being fixed to the top of the mounting plate, and the movable top shell being fixed to the top of the fixed bottom shell by a latch.

[0013] Furthermore, both the protective cavity and the mounting cavity are provided with doors at their openings, and the doors are fixed to the protective box by a latch.

[0014] Furthermore, the bottom of the protective box is provided with support legs, and the sides of the support legs are provided with...

[0015] According to another aspect of the present invention, a static level is provided, which is a static level protected by the impact pressure resistant structure described in any one of the above claims.

[0016] The beneficial effects of this utility model are:

[0017] The design of the connectors allows the hydrostatic level to be fixed inside the protective cavity, while also enhancing the stability of the connection between the connectors, the angle plate guide rail, and the inner wall of the protective cavity.

[0018] The detachable housing design allows for easy maintenance of internal components by disassembling the housing, while also enabling normal use by reassembling it into a single unit.

[0019] Through the design of the impact-resistant seat, when the equipment is used at the construction site, if a falling object hits the impact-resistant seat, the impact seat will be compressed and the load-bearing seat will descend. The descent of the load-bearing seat will push the sliding plate down through the support column. The descent of the sliding plate will compress the damping spring. The damping spring will release its elasticity to absorb the impact force. After absorption, during the process of the sliding plate rising and resetting, due to the travel limitation of the sliding plate by the detachable housing, the sliding plate will only return to its initial position. At the same time, the damping spring will also drive the sliding plate to return to its initial position.

[0020] Because of the impact-resistant seat design, when the impact seat at the top of the impact seat is damaged after a period of use, the damaged impact seat needs to be replaced. That is, unscrew the nut from the end of the threaded rod, then pull the threaded rod out of the impact seat and the connecting rod, and then unscrew the impact seat from the connecting rod.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1, please refer to Figures 1-7This utility model provides a structural solution for resisting impact pressure, including a protective box 1. The protective box 1 has a protective cavity 2. Corner guide rails 3 are provided at the four corners inside the protective cavity 2. A static level instrument body 4 is installed between the four corner guide rails 3. The corner sides of the static level instrument body 4, located between the corner guide rails 3 and the inner wall of the protective cavity 2, are connected and fixed by connectors. The connectors confine the static level instrument body 4 within the protective cavity 2. A mounting cavity 7 is provided on the top side of the protective box 1, and a mounting cavity 7 is placed inside the mounting cavity 7. Mounting plate 8, the top of which is connected to several impact-resistant seats, the impact-resistant seats extending through to the top of the protective box 1, the bottom two sides of the mounting plate 8 respectively pressing on a set of support plates 9, the support plates 9 being laterally slidably connected inside the mounting cavity 7, the bottom of the protective box 1 being provided with support feet, the sides of the support feet being provided with; this utility model can be installed on the construction site to prevent damage from falling objects, when impacted by falling objects, it can buffer the impact force, and at the same time, it can replace the damaged parts when the impact-resistant parts are damaged.

[0032] See Figures 2-3 The connector includes a locking member 5, which is an L-shaped structure with reinforcing flanges at both ends. The reinforcing flanges have bolt holes 6. The corner plate guide rail 3 and the inner wall of the protective cavity 2 are provided with several bolt grooves that mate with the bolt holes 6. The bolt grooves and the bolt holes 6 are fixed together by bolts. Through the design of the connector, the hydrostatic level body 4 is fixed inside the protective cavity 2, and the stability of the connection between the connector, the corner plate guide rail 3 and the inner wall of the protective cavity 2 is enhanced.

[0033] See Figure 4 -and Figure 6The impact-resistant seat includes a detachable housing 10, which is mounted on the top of the mounting plate 8. A sliding plate 14 is slidably connected inside the detachable housing 10. A damping spring 13 connects the inner bottom of the detachable housing 10 and the bottom of the sliding plate 14. A support column 15 is connected to the top center of the sliding plate 14. The top end of the support column 15 extends through the top of the detachable housing 10 and is fixedly connected to a load-bearing seat 16. The top end of the load-bearing seat 16 extends through the top of the protective box 1. A connecting rod 17 is fixed at the top center of the load-bearing seat 16. An external thread 18 is formed on the top of the outer circumference of the connecting rod 17. Two sets of locking holes 19 are formed in a cross shape on the bottom of the outer circumference of the connecting rod 17. The connecting rod 17 is threaded into a threaded groove located at the bottom center of the impact seat 21. At the impact seat 21, an impact ramp 22 is provided on the top. Each of the four ramps of the impact ramp 22 is provided with a groove 23. The four grooves 23 are arranged in a cross shape. Two sets of through holes that cooperate with the locking hole 19 are also provided in the four grooves 23. When the equipment is used at the construction site, if a falling object occurs, when the falling object hits the impact seat, the impact seat 21 is compressed and the load-bearing seat 16 is lowered. The lowering of the load-bearing seat 16 will push the sliding plate 14 to lower through the support column 15. The lowering of the sliding plate 14 will squeeze the damping spring 13. The damping spring 13 is compressed and releases its elastic force to absorb the impact force. After absorption, during the process of the sliding plate 14 rising and resetting, because the detachable housing 10 limits the stroke of the sliding plate 14, the sliding plate 14 will only reset to the initial position. At the same time, the setting of the damping spring 13 will also drive the sliding plate 14 to reset to the initial position.

[0034] See Figure 4 , Figure 7 The impact-resistant seat also includes a snap-fit ​​seat 24 and a snap-fit ​​block 26. The snap-fit ​​seat 24 and the snap-fit ​​block 26 are respectively located in two inclined grooves 23 in the same direction. The top of the load-bearing seat 16 is provided with a snap-fit ​​groove 20 that cooperates with the snap-fit ​​block 26. A threaded rod 25 is fixed in the middle of the side of the snap-fit ​​seat 24. The threaded rod 25 connects and fixes the connecting rod 17 and the impact seat 21 through the through hole and the locking hole 19. A nut 27 is connected to the threaded end of the threaded rod 25 and located outside the snap-fit ​​block 26. When the impact seat 21 at the top of the impact-resistant seat is damaged after a period of use, the damaged impact seat 21 needs to be replaced. That is, unscrew the nut 27 from the end of the threaded rod 25, then pull the threaded rod 25 out of the impact seat 21 and the connecting rod 17, and then unscrew the impact seat 21 from the connecting rod 17.

[0035] See Figures 4-5The detachable housing 10 includes a movable top shell 11 and a fixed bottom shell 12. The fixed bottom shell 12 is fixed to the top of the mounting plate 8, and the movable top shell 11 is fixed to the top of the fixed bottom shell 12 by a latch. Due to the detachable structural design of the detachable housing 10, the detachable housing 10 can be disassembled for maintenance of the internal components, and can be reassembled into a whole for normal use.

[0036] See Figure 1 Both the protective cavity 2 and the mounting cavity 7 have doors at their openings, and the doors are fixed to the protective box 1 by a latch; the design of the doors facilitates operation inside both the protective cavity 2 and the mounting cavity 7.

[0037] According to another aspect of the present invention, a hydrostatic level is provided, wherein the hydrostatic level is a hydrostatic level protected by the impact pressure resistant structure described in any one of the above embodiments.

[0038] The circuits and electronic components, modules and controllers, or the heat dissipation holes and maintenance doors in the space of the adapted electrical equipment are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated. The content protected by this application does not involve improvements to software and methods or heat dissipation and maintenance.

[0039] During the use of the equipment at the construction site, when a falling object impacts the impact seat 21, the impact seat 21 is compressed, causing the load-bearing seat 16 to descend. The descent of the load-bearing seat 16 pushes the sliding plate 14 to descend via the support column 15. The descent of the sliding plate 14 compresses the damping spring 13, which releases its elastic force to absorb the impact. After absorption, during the process of the sliding plate 14 rising and resetting, due to the travel limitation of the detachable housing 10 on the sliding plate 14, the sliding plate 14 will only return to its initial position. At the same time, the damping spring 13 will also cause the sliding plate 14 to return to its initial position. After the impact seat has been used for a period of time, if the impact seat 21 at the top is damaged, the damaged impact seat 21 needs to be replaced. That is, unscrew the nut 27 from the end of the threaded rod 25, then pull the threaded rod 25 out of the impact seat 21 and the connecting rod 17, and then unscrew the impact seat 21 from the connecting rod 17.

[0040] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
