Abstract
Description
Technical Field
[0001] This utility model relates to the field of vibratory leveling tape technology, specifically to a quick-connect device and a concrete vibratory leveling tape suitable for confined spaces. Background Technology
[0002] A concrete vibratory leveling tool is a type of construction machinery mainly used for leveling, vibrating, and grouting large-area concrete surfaces. The reliability of the connection between the motor mounting base and the leveling rod directly affects the vibration performance and service life of the equipment.
[0003] Existing concrete vibratory leveling tools include a vibratory motor, an eccentric transmission device, a motor mounting base, and a ruler. The motor mounting base and the ruler are installed using bolts and nuts. Specifically, bolts are passed through the motor mounting base and the ruler in sequence before being connected to the nut. During the installation or replacement of the ruler, to ensure the reliability of the connection, two wrenches are usually used as auxiliary tools. One wrench is used to fix the bolt, and the other wrench is used to turn the nut. By repeatedly turning the nut, the motor mounting base and the ruler are firmly installed. However, because the space between the motor mounting base and the ruler is relatively narrow, it is inconvenient to place the wrench, and the operating space for turning the wrench is limited. Therefore, during disassembly and assembly, it is necessary to repeatedly take out and put down the wrench and turn the nut, which is extremely cumbersome. Utility Model Content

[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] This utility model provides a quick-connection device suitable for confined spaces, comprising a threaded connector, a limiting member, a clamping member, and a rotating member, wherein: the first end of the threaded connector is fixedly connected to the limiting member, and the limiting member can abut against a first part to be installed to prevent the threaded connector from rotating; the second end of the threaded connector passes sequentially through the first part to be installed, the second part to be installed, and the clamping member, and is threadedly connected to the rotating member; the rotation of the rotating member can drive the threaded connector to move axially, so that the clamping member and the limiting member clamp the first part to be installed and the second part to be installed.

[0016] The quick-connection device and concrete vibrating ruler suitable for confined spaces provided by this utility model have at least the following beneficial effects:
[0017] The quick-connection device suitable for confined spaces includes a threaded connector, a limiting component, a clamping component, and a rotating component. The threaded connector, limiting component, and clamping component cooperate with each other for the installation of the first and second components to be installed.

The second end of the threaded connector passes through the first part to be installed, the second part to be installed, and the clamping member in sequence, and is threadedly connected to the rotating member.

In the aforementioned process, the limiting member and the rotating member are used instead of a wrench.

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0033] Example 1:
[0034] This utility model provides a quick-connection device 1 suitable for confined spaces, see reference. Figures 1 to 9 As shown, the quick-connect device 1 suitable for confined spaces includes a threaded connector 11, a limiting member 12, a clamping member 13, and a rotating member 14. The size of the limiting member 12 is adapted to confined spaces.
[0035] The threaded connector 11 is threadedly engaged with the rotating component 14. The first end of the threaded connector 11 is fixedly connected to the limiting component 12. The threaded connector 11 and the limiting component 12 move synchronously. The limiting component 12 can abut against the first part to be installed, thereby limiting the rotation of the threaded connector 11. The second end of the threaded connector 11 passes through the first part to be installed, the second part to be installed, and the clamping component 13 in sequence, and is threadedly connected to the rotating component 14.
[0036] When installing the first and second parts to be installed, the rotating part 14 is rotated. Since the limiting part 12 is against the first part to be installed, it will not rotate. Therefore, the threaded connection 11 will not rotate. Under the drive of the rotating part 14, it moves axially, thereby driving the limiting part 12 to move synchronously, so that the clamping part 13 and the limiting part 12 clamp the first and second parts to be installed.
[0037] Throughout the aforementioned installation process, no tools such as wrenches are required. Disassembly and assembly can be performed simply by rotating the rotating part 14, making the operation extremely convenient. At the same time, the combination of the threaded connection structure and the clamping structure ensures reliable and secure installation.
[0038] Example 2:
[0039] Example 2 is based on Example 1:
[0040] refer to Figures 1 to 9 As shown, a threaded cavity 141 is provided through the rotating part 14 to engage with the threaded connector 11, and the rotating part 14 is fitted onto the threaded connector 11 through the threaded cavity 141.
[0041] By rotating the rotating part 14, the threaded connector 11 can be effectively moved axially.
[0042] Optionally, the rotating part 14 is configured as a rotating sleeve with a hexagonal shape. In subsequent use, when the rotating part 14 is stuck, it can be rotated by a wrench to achieve disassembly.
[0043] Optionally, a shim 15 is provided between the rotating member 14 and the clamping member 13.
[0044] As an optional implementation, a push handle 142 is integrally provided on the outer wall of the rotating member 14. The overall size of the rotating member 14 with the push handle 142 is smaller than that of a narrow space, and it can rotate freely in a narrow space.
[0045] During the disassembly and assembly process, the user can simply push and pull the handle 142 to rotate the rotating part 14, which further facilitates the operation.
[0046] As an optional implementation, the limiting member 12 is provided with a limiting surface that abuts against the first part to be installed.
[0047] During the disassembly and assembly process, since the threaded connector 11 and the rotating part 14 are threadedly engaged, the threaded connector 11 tends to rotate when the rotating part 14 is rotated. At this time, the limiting surface abuts against the first part to be installed, and the surface contact is used. The force is balanced and the limiting effect is significant, which can effectively prevent the threaded connector 11 from rotating, thereby ensuring its axial movement effect.
[0048] As an optional implementation, the limiting member 12 is provided with a relief groove 121. During the installation process, when the threaded connector 11 and the limiting member 12 move axially, the relief groove 121 can effectively give way to the structural components on the first part to be installed, thus avoiding interference.
[0049] Specifically, when the first component to be installed and the second component to be installed are the mounting base 2 and the ruler rod 3 of the vibrating ruler, the bolt head 22 of the bolt used to install the shock-absorbing pad on the mounting base 2 is located on the bottom side of the mounting base 2. The bolt head 22 is the aforementioned structural component. The clearance groove 121 is provided to allow the bolt head 22 to be properly placed into the narrow space at the bottom of the mounting base 2.
[0050] As an optional implementation, the limiting member 12 is configured as a limiting plate, which is welded to the end of the threaded connector 11.
[0051] The limiting plate abuts against the outer wall surface of the first part to be installed, forming the limiting surface.
[0052] The limiting component 12 adopts a plate structure, which is convenient for processing and production. On the other hand, it has surface contact with the first part to be installed, making the clamping more stable and firm.
[0053] As an optional implementation, the clamping member 13 is configured as a clamping plate. The clamping member 13 adopts a plate structure, which is convenient for processing and has surface contact with the second part to be installed, making the clamping more stable and firm.
[0054] The clamping plate is provided with mounting holes 131 at the positions corresponding to the threaded connector 11.
[0055] The first component to be installed has a first through hole 21 at the position corresponding to the mounting hole 131, and the second component to be installed has a second through hole 31 at the position corresponding to the mounting hole 131.
[0056] As an optional implementation, the number of threaded connectors 11, limiting members 12, and rotating members 14 is set to multiple.
[0057] Preferably, the number of threaded connector 11, limiting member 12 and rotating member 14 is set to two, and they are arranged symmetrically from left to right.

[0061] The concrete vibratory leveling device using the aforementioned quick-connection mechanism can install the leveling rod 3 and the mounting base 2 without any tools during use. This not only makes disassembly and assembly convenient and improves efficiency, but also ensures a firm and reliable installation, guaranteeing the leveling effect.
[0062] As an optional implementation, the concrete vibrating ruler includes a ruler rod 3 and a mounting base 2, wherein the mounting base 2 is the first part to be installed and the ruler rod 3 is the second part to be installed.
[0063] Mounting base 2 is located on the upper side of ruler rod 3. Mounting base 2 includes a horizontal base and a first vertical plate integrally formed with the horizontal base. The space between the lower part of the horizontal base and the ruler rod 3 is a narrow space. A first through hole 21 is provided through the first vertical plate. The limiting member 12 is located below the horizontal base, and its top abutting surface abuts against the bottom surface of the horizontal base. Ruler rod 3 is provided with a second vertical plate, and a second through hole 31 is provided through the second vertical plate. The second end of the threaded connector 11 passes through the first through hole 21, the second through hole 31, and the mounting hole 131 in sequence, and is then threadedly connected to the rotating member 14.
[0064] When installing the ruler rod 3 and the mounting base 2, rotate the rotating part 14, the limiting part 12 abuts against the bottom surface of the mounting base 2, the threaded connecting part 11 moves axially, and drives the limiting part 12 to move synchronously, thereby firmly clamping the first vertical plate and the second vertical plate with the clamping part 13. The installation is not only firm and reliable, but also convenient and quick to operate.
