Description

Technical Field

[0001] This utility model relates to the field of flexible head support technology, and in particular to a flexible head support that is easy to assemble and disassemble. Background Technology

[0002] A flexible support head is a functional component used in equipment installation, component support, or connection scenarios. Its core function is to provide a stable support foundation while having the ability to adjust the angle, adapt the position, or compensate for slight displacement. It can flexibly adapt to different installation angles, force directions, or component gaps according to actual support needs, eliminating support adaptation problems caused by installation errors or component deformation. It ensures a stable and close connection between the support structure and the supported component, providing reliable support for the stable operation of equipment or components.

[0003] Existing flexible support heads typically require multiple tools to install and remove the limiting components. Furthermore, the adjustable support length range of the limiting components is narrow, making it difficult to flexibly meet the support needs of different pit widths. After limiting, the components are prone to loosening or falling off due to stress, resulting in insufficient support stability. Moreover, subsequent adjustments to the support length are difficult to find quickly, requiring complex tools and resulting in high labor and time costs and low reuse rate.

[0004] Therefore, a flexible support head that is easy to assemble and disassemble is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a support hinge that is easy to assemble and disassemble, which can solve the problems of existing support hinges that usually require multiple tools to install and disassemble the limiting component, and the limited range of support length adjustment that the limiting component can adapt to is narrow, making it difficult to flexibly meet the support requirements of different foundation pit widths. After limiting, it is easy to loosen or fall off due to force, resulting in insufficient support stability. Furthermore, subsequent adjustment of the support length is difficult to find a suitable point quickly, requiring complex tools, resulting in high labor time costs and low reuse rate.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a conveniently assembled and disassembled support head, comprising a first mounting plate, an outer cylinder welded to the top of the first mounting plate, an inner cylinder movably connected to the inner wall of the outer cylinder, a second mounting plate welded to the top of the inner cylinder, a limiting mechanism inserted into the inner wall of the outer cylinder, the surface of the limiting mechanism being inserted into the inner wall of the inner cylinder, a placement platform welded to the surface of the outer cylinder, a cover rotatably connected to the inner wall of the outer cylinder, the limiting mechanism comprising a pulling frame, a limiting plate fixedly connected to the rear side of the pulling frame, and a rod fixedly connected to the rear side of the limiting plate.

[0007] Preferably, the surface of the insertion rod is inserted into the inner wall of the outer cylinder, and the surface of the insertion rod is inserted into the inner wall of the inner cylinder.

[0008] Preferably, the inner wall of the outer cylinder is provided with a first limiting hole for use with the insertion rod, and the inner wall of the inner cylinder is provided with a second limiting hole for use with the insertion rod.

[0009] Preferably, the inner wall of the outer cylinder is provided with an adjustment groove that works in conjunction with the inner cylinder, and the rear side of the limiting plate contacts the front side of the outer cylinder.

[0010] Preferably, a connecting block is welded to the left side of the cover, and a pull rod is welded to the front side of the connecting block.

[0011] Preferably, a reinforcing block is welded to the top of the first mounting plate, and the side of the reinforcing block closest to the outer cylinder is welded to the outer cylinder.

[0012] Preferably, an adjusting block is welded to the left side of the outer cylinder, and the inner wall of the adjusting block is provided with a pulling hole.

[0013] Preferably, the left side of the placement platform is provided with anti-slip texture, and the inner wall of the first mounting plate is provided with pre-installation holes.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This application sets up a limiting mechanism, which can easily drive the limiting plate and the insertion rod to move through the pull frame, so that the insertion rod can be quickly inserted into the outer cylinder and the inner cylinder to achieve the limiting position. No complicated special tools are required, which greatly simplifies the assembly and disassembly process of the outer cylinder and the inner cylinder, saving manpower and time. The insertion rod can flexibly adjust the limiting point according to the extension and retraction position of the outer cylinder and the inner cylinder to adapt to different support length requirements, ensuring the structural stability of the support movable head in the foundation pit support. Even when the external pressure of the foundation pit is high, the insertion rod can stably limit the position and prevent the support from shifting. 2. This application, by setting a first mounting plate, ensures the structural strength of the connection between the support hinge and external components through welding the first mounting plate to the outer cylinder and the second mounting plate to the inner cylinder during use. This prevents the connection parts from shifting vertically or falling off due to stress, thus improving overall stability. The placement platform on the surface of the outer cylinder can temporarily store tools and also allow workers to stand and operate the pins, solving the problems of difficult tool storage and insufficient operating space during construction. The rotating cover on the inner wall of the outer cylinder (the bottom of the cover opening and closing is used to place the jack) can cover the cylinder opening, preventing concrete, soil and other debris from entering the gap between the outer and inner cylinders during other construction processes. This avoids debris causing expansion and contraction jamming, ensuring smooth subsequent disassembly and assembly, reducing the extra workload of cleaning debris. At the same time, the overall structure is easy to install and disassemble, which can shorten the construction cycle and reduce the fatigue of construction workers. Attached Figure Description

[0017] 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 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.

[0018] Please see Figure 1-6 The present invention provides the following technical solution: A conveniently assembled and disassembled support head includes a first mounting plate 1, an outer cylinder 3 welded to the top of the first mounting plate 1, an inner cylinder 4 movably connected to the inner wall of the outer cylinder 3, a second mounting plate 5 welded to the top of the inner cylinder 4, a limiting mechanism 2 inserted into the inner wall of the outer cylinder 3, the surface of the limiting mechanism 2 being inserted into the inner wall of the inner cylinder 4, a placement platform 6 welded to the surface of the outer cylinder 3, a cover 7 rotatably connected to the inner wall of the outer cylinder 3, the limiting mechanism 2 including a pulling frame 201, a limiting plate 202 fixedly connected to the rear side of the pulling frame 201, and a plug rod 203 fixedly connected to the rear side of the limiting plate 202.

[0019] In this embodiment: By setting a limiting mechanism 2, the limiting mechanism 2 can easily drive the limiting plate 202 and the insertion rod 203 to move via the pulling frame 201, so that the insertion rod 203 can quickly insert into the outer cylinder 3 and the inner cylinder 4 to achieve limiting, without the need for complicated special tools, greatly simplifying the assembly and disassembly process of the outer cylinder 3 and the inner cylinder 4, saving manpower and time. The insertion rod 203 can flexibly adjust the limiting point according to the extension and retraction position of the outer cylinder 3 and the inner cylinder 4 to adapt to different support length requirements, ensuring the structural stability of the support hinge in the foundation pit support. Even when the external pressure of the foundation pit is high, the insertion rod 203 can stably limit the position and prevent the support from shifting. By setting a first mounting plate 1, in use, the first mounting plate 1 connects to the outer cylinder 3, and the second mounting plate 5 connects to the inner cylinder 4. The welded connection ensures the structural strength of the connection between the support hinge and the external components, preventing the connection from shifting or falling off due to stress, thus improving overall stability. The placement platform 6 on the surface of the outer cylinder 3 can temporarily store tools and also allow workers to stand and operate the pins, solving the problems of difficult tool storage and insufficient operating space during construction. The rotating cover 7 on the inner wall of the outer cylinder 3 (the bottom of the opening and closing part of the cover 7 is used to place the jack) can cover the cylinder opening, preventing concrete, soil and other debris from entering the gap between the outer cylinder 3 and the inner cylinder 4 during other construction processes, avoiding debris from causing expansion and contraction jams, ensuring smooth subsequent disassembly and assembly, reducing the extra workload of cleaning debris, and at the same time, the overall structure is easy to install and disassemble, which can shorten the construction cycle and reduce the fatigue of construction workers.

[0020] Specifically, such as Figure 1 , Figure 2 As shown, the surface of the insertion rod 203 is inserted into the inner wall of the outer cylinder 3, and the surface of the insertion rod 203 is inserted into the inner wall of the inner cylinder 4.

[0021] Specifically, such as Figure 3 , Figure 6 As shown, the inner wall of the outer cylinder 3 is provided with a first limiting hole 8 for use with the insertion rod 203, and the inner wall of the inner cylinder 4 is provided with a second limiting hole 9 for use with the insertion rod 203.

[0022] Specifically, such as Figure 1 , Figure 6 As shown, the inner wall of the outer cylinder 3 is provided with an adjustment groove 10 that works with the inner cylinder 4, and the rear side of the limiting plate 202 contacts the front side of the outer cylinder 3.

[0023] In this embodiment: the insertion rod 203 is inserted into the outer cylinder 3 and the inner cylinder 4 respectively. With the first limiting hole 8 on the inner wall of the outer cylinder 3 (adjacent first limiting holes 8 are not on the same straight line and are staggered, with a hole distance of 3cm between two adjacent first limiting holes 8) and the second limiting hole 9 on the inner wall of the inner cylinder 4, the positioning and limiting of the outer cylinder 3 and the inner cylinder 4 can be accurately realized. Moreover, the insertion position of the insertion rod 203 can be flexibly adapted to different support lengths to meet the needs of the pit width variation. Even when the external pressure of the pit is high, the stable insertion of the insertion rod 203 and the hole position can prevent the support from shifting. The adjustment groove 10 opened on the inner wall of the outer cylinder 3 and used in conjunction with the inner cylinder 4 provides guidance for the extension and retraction movement of the inner cylinder 4 in the outer cylinder 3, preventing the inner cylinder 4 from deviating and jamming during extension and retraction, and ensuring smooth adjustment. The rear side of the limiting plate 202 contacts the front side of the outer cylinder 3, which can form an axial limit on the insertion rod 203, preventing the insertion rod 203 from being over-inserted during the force process, and further improving the reliability of the limiting mechanism 2.

[0024] Specifically, such as Figure 4 As shown, a connecting block 11 is welded to the left side of the cover 7, and a pull rod 12 is welded to the front side of the connecting block 11.

[0025] Specifically, such as Figure 4 As shown, a reinforcing block 13 is welded to the top of the first mounting plate 1, and the reinforcing block 13 is welded to the outer cylinder 3 on the side close to the outer cylinder 3.

[0026] In this embodiment: By setting a connecting block 11 and a pulling rod 12, the operator can easily drive the connecting block 11 and the cover 7 to rotate synchronously by pulling the rod 12, so as to realize the rapid opening and closing of the cover 7 (the cover 7 is rotatably connected to the outer cylinder 3 via a hinge) without the need for additional tools. This makes it easy to quickly open the cover 7 when the jack needs to be placed, and also to close the cover 7 in time during construction breaks to block the cylinder opening and prevent debris from entering. The reinforcing block 13 welded to the top of the first mounting plate 1 is welded to the outer cylinder 3, which can enhance the connection strength between the first mounting plate 1 and the outer cylinder 3, and prevent the welded parts from breaking and falling off due to long-term stress or vertical displacement of the support. This further improves the overall structural stability of the support hinge head and extends its service life.

[0027] Specifically, such as Figure 6 As shown, an adjusting block 14 is welded to the left side of the outer cylinder 3, and a pulling hole 15 is provided on the inner wall of the adjusting block 14.

[0028] Specifically, such as Figure 4 , Figure 5 As shown, the left side of the placement platform 6 is provided with anti-slip texture 16, and the inner wall of the first mounting plate 1 is provided with pre-installation holes 17.

[0029] In this embodiment: By setting the adjustment block 14, a convenient force application point is provided for the operator. When adjusting the position of the outer cylinder 3 or assisting in disassembly and assembly, external force can be applied through the pull hole 15, reducing the difficulty of operation and improving the convenience of construction. The anti-slip texture 16 set on the left side of the placement platform 6 can increase the friction between the tool or the worker's foot and the surface of the placement platform 6, preventing the tool from slipping or the worker from slipping when standing and operating, thus improving the safety of use. The pre-installation hole 17 opened on the inner wall of the first mounting plate 1 can be pre-positioned and installed before the support hinge head is connected to the external components, which facilitates quick alignment of the installation position, reduces installation and adjustment time, and improves the overall installation efficiency.

[0030] Working principle: During the use of the first mounting plate 1, a limiting mechanism 2 is set up. The limiting mechanism 2 can easily drive the limiting plate 202 and the insertion rod 203 to move through the pulling frame 201, so that the insertion rod 203 can quickly insert into the outer cylinder 3 and the inner cylinder 4 to achieve the limiting position. No complicated special tools are required, which greatly simplifies the assembly and disassembly process of the outer cylinder 3 and the inner cylinder 4, saving manpower and time. The insertion rod 203 can flexibly adjust the limiting point according to the extension and retraction position of the outer cylinder 3 and the inner cylinder 4 to adapt to different support length requirements, ensuring the structural stability of the support hinge in the foundation pit support. Even when the external pressure of the foundation pit is high, the insertion rod 203 can stably limit the position and prevent the support from shifting. By setting the first mounting plate 1, during use, the first mounting plate 1 connects with the outer cylinder 3 and the second mounting plate 202. The welded connection between plate 5 and inner cylinder 4 ensures the structural strength of the connection between the support hinge and the external components, preventing the connection from shifting or falling off due to stress, thus improving overall stability. The placement platform 6 on the surface of outer cylinder 3 can temporarily store tools and also allows workers to stand and operate the pins, solving the problems of difficult tool storage and insufficient operating space during construction. The rotating cover 7 on the inner wall of outer cylinder 3 (the bottom of the opening and closing part of cover 7 is used to place the jack) can cover the cylinder opening, preventing concrete, soil and other debris from entering the gap between outer cylinder 3 and inner cylinder 4 during other construction processes, avoiding debris causing expansion and contraction jamming, ensuring smooth subsequent disassembly and assembly, reducing the extra workload of cleaning debris, and at the same time, the overall structure is easy to install and disassemble, which can shorten the construction cycle and reduce the fatigue of construction workers.

[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
