[0033] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0034] like Figures 1 to 4 As shown, this embodiment of the utility model provides a leveling support device, including:

[0035] A base 100, on which a first telescopic arm 102 is provided;

[0036] Support arm 104 is located at the end of the first telescopic arm 102 that is away from the base 100;

[0037] The second telescopic arm 106 is disposed at both ends of the support arm 104, and an adsorption element 108 is disposed on the second telescopic arm 106.

[0038] Support 110, provided at the end of the support arm 104 away from the first telescopic arm 102.

[0039] According to the leveling support device provided in the embodiment of the utility model, the telescopic function of the first telescopic arm 102 and the second telescopic arm 106 can adjust the height and range of the whole leveling support device. The height adjustability makes the device adapt to objects to be leveled at different heights and ranges, improving the versatility and flexibility of the device. When the gap between the cross beam and the floor needs to be adjusted, the leveling support device can be placed at the bottom of the cross beam, adsorbed to the bottom of the floor by the suction accessory 108, and then the support 110 is used to lift the cross beam, compensating the gap between the cross beam and the floor. The suction accessory 108 can also be adsorbed to the plane to be adjusted, and the leveling of the plane to be adjusted is realized by adjusting the support 110. This fine adjustment capability makes the leveling support device applicable to fine adjustment of uneven floors. The leveling support device is easy and simple to operate. The operator only needs to control the telescoping of the first telescopic arm 102 and the second telescopic arm 106, the adsorption of the suction accessory 108, and the lifting of the support 110 to complete the leveling support work, reducing the operation difficulty and labor intensity.

[0040] Please continue to see Figures 1 to 4 The base 100 is the basis of the whole leveling support device, and has sufficient stability and load-bearing capacity. The first telescopic arm 102 is arranged on the base 100 and used to adjust the height of the support arm 104. The first telescopic arm 102 can realize the telescopic function by means of, for example, hydraulic pressure, machinery, etc., thereby adjusting the height of the support arm 104. One end of the first telescopic arm 102 is connected with the base 100, and the other end is connected with the support arm 104.

[0041] The support arm 104 is arranged at the end of the first telescopic arm 102 away from the base 100 and used to support the second telescopic arm 106. The support arm 104 has certain rigidity and strength to ensure the stability and safety of the device.

[0042] The second telescopic arm 106 is arranged at both ends of the support arm 104 and realizes more fine adjustment through the telescopic function. The suction accessory 108, such as a suction cup, a magnet, etc., is arranged on the second telescopic arm 106 and used to adsorb or fix the object to be leveled or the plane to be leveled. The design of the suction accessory 108 should be selected according to the material and shape of the object to be leveled to ensure the adsorption effect.

[0043] The support 110 is arranged at the end of the support arm 104 away from the first telescopic arm 102 and used to further realize fine height adjustment. In the embodiment of the utility model, the support 110 can use a jack, a screw rod, etc. to realize more fine height adjustment support.

[0044] According to an embodiment of the present application, the first telescopic arm 102 comprises:

[0045] The first support cylinder 112 is connected to the base 100 at the first end thereof;

[0046] The first screw rod 114 is telescopically arranged at the second end of the first support cylinder 112, and the support arm 104 is rotationally connected to one end of the first screw rod 114 extending out of the first support cylinder 112.

[0047] In the embodiment of the present application, the structure of the first telescopic arm 102 is defined and optimized in detail. The first support cylinder 112 serves as the main structure of the first telescopic arm 102 and has sufficient strength and rigidity to support the weight of the entire device. The first end (i.e., the bottom) of the first support cylinder 112 is connected to the base 100, ensuring the stability of the entire device during the leveling process. The interior of the first support cylinder 112 is designed with threads or sliding grooves and the like to cooperate with the first screw rod 114 to realize the telescopic function.

[0048] The first screw rod 114 is a component telescopically arranged at the second end (i.e., the top) of the first support cylinder 112. The exterior of the first screw rod 114 is designed with threads or protrusions matching the internal threads or sliding grooves of the first support cylinder 112, allowing the first screw rod 114 to smoothly telescope within the first support cylinder 112.

[0049] One end of the first screw rod 114 extending out of the first support cylinder 112 is rotationally connected to the support arm 104. This rotational connection allows the support arm 104 to rotate relative to the first screw rod 114 (and the entire first telescopic arm 102) within a certain range, thereby achieving adjustment of the support arm 104 relative to the first screw rod 114 in the height direction.

[0050] By rotating the first screw rod 114, the height of the support arm 104 can be accurately adjusted. Since the threads or sliding grooves between the first screw rod 114 and the first support cylinder 112 are tightly matched, the adjustment process is stable and less prone to shaking. The design of the first telescopic arm 102 makes the entire device compact in structure, occupies less space, and is convenient to carry and transport. At the same time, since the connection structure between the first screw rod 114 and the first support cylinder 112 is relatively simple, it is easy to maintain and maintain, thereby reducing the use cost. The rotational connection between the support arm 104 and the first screw rod 114 allows the device to rotate and adjust to a certain extent during the leveling process to adapt to different heights and sizes of objects to be leveled.

[0051] According to an embodiment of the present application, a retainer 116 is arranged between the first support cylinder 112 and the base 100.

[0052] In the embodiment of the utility model, the first support cylinder 112 and the base 100 are provided with a retainer 116. This design aims to further enhance the structural stability and durability of the leveling support device.

[0053] The retainer 116, as a key component connecting the first support cylinder 112 and the base 100, is designed to disperse and bear the weight and pressure from the upper part of the device (including the first telescopic arm 102, the support arm 104, the second telescopic arm 106, the suction accessory 108, etc.).

[0054] By optimizing the structure and material of the retainer 116, it can ensure that the device still maintains stable performance when used for a long time or bears a large load.

[0055] The retainer 116 can be made of metal (such as steel, aluminum alloy, etc.), and the specific selection depends on the use environment and requirements of the device. The shape and size of the retainer 116 should be customized according to the connection method of the first support cylinder 112 and the base 100, the overall size of the device, and the required load bearing.

[0056] One end of the retainer 116 is fixedly connected with the lower part of the first support cylinder 112, and the connection method can include welding, bolt connection, riveting, etc. The other end of the retainer 116 is fixedly connected with the base 100, and can also use reliable methods such as welding and bolt connection. Through this connection method, the retainer 116 can effectively connect the first support cylinder 112 and the base 100 into a whole, improving the overall stability and rigidity of the device.

[0057] The setting of the retainer 116 significantly enhances the structural stability of the leveling support device. When bearing a large load or being used for a long time, the device can maintain stable performance and is not prone to deformation or damage. As a key component connecting the first support cylinder 112 and the base 100, the retainer 116 enhances the overall rigidity of the device. This helps to reduce the shaking and tilting of the device during leveling, improves the leveling accuracy and safety. The design of the retainer 116 makes its installation and maintenance relatively simple. When it needs to be replaced or repaired, the retainer 116 can be easily disassembled and reinstalled, reducing maintenance cost and time.

[0058] According to one embodiment of the utility model, the base 100 is provided with a support rod 118, the support rod 118 is coaxially arranged with the first support cylinder 112, and the support rod 118 penetrates the thickness direction of the base 100 and is connected with the first support cylinder 112.

[0059] In the embodiment of the utility model, the base 100 is provided with a support rod 118, this design aims at further enhancing the structural strength, stability and precision of the leveling support device. The support rod 118 is coaxially arranged with the first support cylinder 112 and penetrates the thickness direction of the base 100, and finally is connected with the first support cylinder 112.

[0060] As an additional structural element connecting the base 100 and the first support cylinder 112, the support rod 118 can significantly enhance the structural strength of the entire device, enabling it to withstand greater loads and more complex stress states. The coaxially arranged support rod 118 ensures precise alignment between the base 100 and the first support cylinder 112, reducing the shaking and tilting caused by misalignment, thereby improving the overall stability of the device. The presence of the support rod 118 helps maintain the precise position of the first support cylinder 112 in the vertical direction, which is particularly important for situations requiring high-precision leveling.

[0061] The connection method of the support rod 118 with the base 100 and the first support cylinder 112 may include welding, bolt connection, riveting, etc. These connection methods should ensure the firmness and reliability of the connection, while facilitating installation and maintenance. One end of the support rod 118 is connected to the base 100, and the other end of the support rod 118 should be connected to the lower part of the first support cylinder 112, and the connection method also needs to ensure firmness and reliability.

[0062] The arrangement of the support rod 118 significantly enhances the structural strength of the leveling support device, enabling it to withstand greater loads and more complex stress states, improving the durability and reliability of the device. The coaxially arranged support rod 118 ensures precise alignment between the base 100 and the first support cylinder 112, reducing the shaking and tilting caused by misalignment, thereby improving the overall stability and leveling precision of the device. The presence of the support rod 118 helps maintain the precise position of the first support cylinder 112 in the vertical direction, which is particularly important for situations requiring high-precision leveling. It reduces errors caused by structural deformation or loosening, improving leveling precision and reliability.

[0063] According to an embodiment of the utility model, an elastic buffer 120 is arranged between the end of the first support cylinder 112 facing the base 100 and the base 100.

[0064] In the embodiment of the utility model, an elastic buffer 120 is arranged between the end of the first support cylinder 112 facing the base 100 and the base 100. This design aims to reduce the negative impact of the device when subjected to impact or vibration, improving the stability and durability of the device.

[0065] The elastic buffer 120 can effectively absorb and disperse the energy generated by the device when subjected to impact or vibration, reducing the influence of these external factors on the stability and accuracy of the device. By setting the elastic buffer 120, the direct impact and friction between the base 100 and the first support cylinder 112 can be reduced, thereby prolonging the service life of the device and reducing maintenance costs. The presence of the elastic buffer 120 enables the device to recover to a stable state more quickly when subjected to external disturbances, improving the device's disturbance resistance and stability.

[0066] The elastic buffer 120 can be made of rubber, springs, elastic plastics, or other materials with excellent elasticity and wear resistance. These materials should be able to withstand certain compression and shear deformation while maintaining good resilience and durability.

[0067] According to an embodiment of the present application, the support arm 104 is provided with a locking member 122, and the support arm 104 is adapted to be locked with the first screw 114 by the locking member 122.

[0068] In the embodiment of the present application, the locking member 122 is provided on the support arm 104, so that the support arm 104 can be accurately locked at a certain specific position on the first screw 114. This design aims to enhance the stability and accuracy of the device, while improving the convenience and reliability of operation.

[0069] The locking member 122 is a key component for locking the relative position of the support arm 104 and the first screw 114, which can adopt a threaded locking mechanism, a buckle locking mechanism, or a combination of bolts and nuts, etc. The design of the locking member 122 needs to ensure that the support arm 104 can be firmly fixed at the desired position, while being easy to install and remove.

[0070] When the support arm 104 needs to be locked at a certain position on the first screw 114, the user can operate the locking member 122 (such as rotating the threaded locking member 122, pressing the buckle locking member 122, etc.) to fix the support arm 104 at the desired position. During the locking process, the locking member 122 will be in close contact or cooperation with the first screw 114, thereby preventing the support arm 104 from moving or deviating when subjected to external forces. By reasonably selecting the locking force and the locking method, the stability and accuracy of the support arm 104 in the locked state can be ensured.

[0071] By locking the support arm 104 on the first screw 114 with the locking piece 122, the position deviation of the support arm 104 caused by external factors such as vibration and impact can be significantly reduced, thereby improving the stability of the entire device. The design of the locking mechanism allows the support arm 104 to be accurately positioned at a certain position on the first screw 114, thereby ensuring the accuracy requirements of the device during operation. This is particularly important for application scenarios that require high-precision positioning and adjustment. The design of the locking piece 122 allows users to easily install, disassemble and adjust the position of the support arm 104, thereby improving the convenience and efficiency of operation.

[0072] According to an embodiment of the present application, a sleeve 124 is provided on the support arm 104, and the sleeve 124 is rotationally connected to one end of the first screw 114 extending out of the first support cylinder 112.

[0073] In the embodiment of the present application, a sleeve 124 is provided on the support arm 104, and the sleeve 124 is rotationally connected to one end of the first screw 114 extending out of the first support cylinder 112. This design aims to provide a flexible and stable connection method to meet the needs of different application scenarios.

[0074] The sleeve 124 has an inner hole that matches the first screw 114, so that it can be tightly fitted on the first screw 114 and rotationally connected. The rotational connection between the sleeve 124 and the first screw 114 can be achieved in various ways, such as bearing connection, threaded connection, lubricant, etc. This rotational connection allows the support arm 104 to rotate relative to the first screw 114 within a certain range, thereby increasing the flexibility and applicability of the device.

[0075] When it is necessary to adjust the position or angle of the support arm 104, the user can rotate the sleeve 124 on the support arm 104 to achieve this. Since the sleeve 124 is rotationally connected to the first screw 114, the support arm 104 can be rotated and adjusted without changing the position of the first screw 114. This design not only improves the flexibility of the device, but also makes the operation more convenient and efficient.

[0076] The rotational connection between the sleeve 124 and the first screw 114 allows the support arm 104 to rotate and adjust within a certain range, thereby meeting the needs of different application scenarios. The tight fit between the sleeve 124 and the first screw 114 ensures the stability and reliability of the connection. Even when subjected to external forces, the support arm 104 can maintain a stable connection state and will not fall off or loosen. By rotating the sleeve 124, the position or angle of the support arm 104 can be adjusted without the need for complex disassembly and reinstallation process. This greatly improves the simplicity and efficiency of operation.

[0077] According to an embodiment of the present application, a reinforcing member 126 is arranged between the first support cylinder 112 and the sleeve 124.

[0078] In the embodiment of the present application, a reinforcing member 126 is arranged between the first support cylinder 112 and the sleeve 124. This design aims to enhance the connection strength between the first support cylinder 112 and the sleeve 124, and improve the stability and durability of the entire structure.

[0079] The reinforcing member 126 is an additional structure arranged between the first support cylinder 112 and the sleeve 124, used to enhance the connection strength between the two. The reinforcing member 126 can adopt various shapes and materials, such as ring, plate or other customized shapes, usually made of high-strength materials such as metal, alloy or composite materials.

[0080] The reinforcing member 126 can be fixed between the first support cylinder 112 and the sleeve 124 by welding, bolting, riveting or other means. The choice of connection method should ensure that the reinforcing member 126 can firmly connect the two, while not damaging the integrity and performance of the original structure.

[0081] The design principle of the reinforcing member 126 is to enhance the connection strength between the first support cylinder 112 and the sleeve 124 by adding additional support and connection points. When external loads act on the support structure, the reinforcing member 126 can disperse and bear part of the load, thereby reducing the stress on the first support cylinder 112 and the sleeve 124, and improving the stability and durability of the entire structure.

[0082] The presence of the reinforcing member 126 significantly enhances the connection strength between the first support cylinder 112 and the sleeve 124, making the entire structure more stable and durable. By adding the reinforcing member 126, the support structure can maintain stability when subjected to external loads, and is not prone to deformation or damage. The reinforcing member 126 can disperse and bear part of the load, thereby reducing the stress on the first support cylinder 112 and the sleeve 124, and prolonging the service life of the entire structure.

[0083] According to an embodiment of the present application, the second telescopic arm 106 comprises:

[0084] The second support cylinder 128 is connected to both ends of the support arm 104.

[0085] The second screw rod 130 is telescopically arranged in the second support cylinder 128, and the suction member 108 is arranged at one end of the second screw rod 130 away from the base 100.

[0086] In the embodiments of the present application, the second telescopic arm 106 is mainly composed of a second supporting cylinder 128 and a second screw rod 130. The second supporting cylinder 128 is connected to the two ends of the supporting arm 104, and the second screw rod 130 is telescopically arranged in the second supporting cylinder 128. The suction accessory 108 is arranged at one end of the second screw rod 130 away from the base 100. This design aims to provide a flexible and adjustable length telescopic arm to meet the needs of different application scenarios.

[0087] The second supporting cylinder 128 generally has sufficient strength and rigidity to withstand loads from the outside or inside. At the same time, the inner wall of the second supporting cylinder 128 is generally designed with threads or grooves matched with the second screw rod 130, so that the second screw rod 130 can perform telescopic movement therein.

[0088] The second screw rod 130 is a component telescopically arranged in the second supporting cylinder 128. One end thereof is connected to the suction accessory 108, and the other end can perform telescopic movement in the second supporting cylinder 128.

[0089] When the length of the second telescopic arm 106 needs to be adjusted, the user can achieve it by rotating or pushing and pulling the second screw rod 130. Since the second screw rod 130 and the second supporting cylinder 128 are in a matching relationship (such as thread matching or groove matching), the second screw rod 130 can perform telescopic movement in the second supporting cylinder 128, thereby changing the overall length of the second telescopic arm 106. When the second screw rod 130 is extended to the desired position, the second telescopic arm 106 can be firmly connected with the supporting arm 104 through the connecting mechanism. At this time, the suction accessory 108 can be used to suck or fix other objects.

[0090] By telescopic movement of the second screw rod 130 in the second supporting cylinder 128, the length of the second telescopic arm 106 can be conveniently adjusted to meet the needs of different application scenarios. Since the second supporting cylinder 128 and the second screw rod 130 are in a matching relationship, the second telescopic arm 106 can remain stable when subjected to external forces and is not prone to deformation or damage. The length adjustment of the second telescopic arm 106 can be achieved by simple rotating or pushing and pulling action, without the need for complex disassembly and reinstallation process.

[0091] According to an embodiment of the present application, the base 100 is provided with universal wheels 132 on the side away from the first telescopic arm 102.

[0092] In the embodiments of the present application, the base 100 is provided with universal wheels 132 on the side away from the first telescopic arm 102. This design aims to provide a device that can be flexibly moved and adjusted in position to meet the needs of different application scenarios.

[0093] The universal wheels 132 generally have flexible steering capability and good load-bearing performance, enabling the entire device to move and adjust position flexibly on the ground. The specific form of the universal wheels 132 can be selected according to application requirements, such as universal wheels 132 with brakes, silent universal wheels 132, etc.

[0094] When it is necessary to move or adjust the position of the device, the user can push or pull the device to move flexibly on the ground by taking advantage of the flexible steering capability of the universal wheels 132. At the same time, since the universal wheels 132 have good load-bearing performance, it can be ensured that the entire device remains stable during movement. In addition, if universal wheels 132 with brakes are selected, the user can also lock the universal wheels 132 when needed to prevent accidental movement of the device.

[0095] By providing universal wheels 132, the entire device can move and adjust position flexibly on the ground, thereby meeting the needs of different application scenarios. The user can achieve movement of the device by simply pushing or pulling, without the need for complex disassembly and reinstallation processes, greatly improving the convenience of operation. The universal wheels 132 generally have good load-bearing performance and stable steering capability, which can ensure that the entire device remains stable during movement and is not prone to tipping over or damage.
