[0036] Example:

[0037] A push handle frame for a track geometry detection trolley includes an outer sleeve 20, one end of which is detachably connected to a quick-connect component 10, and the other end of which is detachably connected to a retractable component 90. An adjustment component 30 for adjusting the position is provided at the connection between the outer sleeve 20 and the retractable component 90;

[0038] The end of the retracted component 90 away from the adjusting component 30 is detachably connected to a connector 80, the connecting component 60 is detachably connected to the connector 80, the bottom of the connecting component 60 is detachably connected to a clamping component 50, and the clamping component 50 and the connecting component 60 are detachably clamped to hold the push handle 40;

[0039] The quick-connect component 10 is further provided with a tightening component 70 for quickly fixing to the trolley.

[0040] To illustrate, one end of the outer sleeve 20 is connected to the quick-connect component 10, and the other end is connected to the retracting component 90. The quick-connect component 10 can be quickly connected to a trolley or other equipment. The quick-connect design can reduce loading and unloading time and improve usage efficiency. The retracting component 90 cooperates with the adjustment component 30 to adjust the length or reduce the structure of the push handle when needed, making it easy to store or adjust to the appropriate size when not in use. The adjustment component 30 is located at the connection between the outer sleeve 20 and the retracting component 90. The adjustment component 30 allows the position between the outer sleeve 20 and the retracting component 90 to be adjusted, thereby ensuring that it can adapt to different track geometries or detection requirements.

[0041] Specifically, the retracted part 90 fixed by the connector 80 is away from one end of the adjustment part 30, and can provide a connection interface for the subsequent connecting part 60, playing a transition and connection role. The connecting part 60 is connected to the connector 80 and can be further connected to the clamping part 50 by disassembling the connection. The clamping part 50 is located at the bottom of the connecting part 60. The push handle part 40 and the clamping part 50 can be disassembled and clamped. The push handle part 40 can be fixed on the clamping part 50 to push or manipulate the detection equipment. The design purpose of the push handle part 40 is to enable the trolley or detection equipment to move along the track to ensure that the inspection of the track geometry can be carried out smoothly. The tightening part 70 equipped on the quick-connect part 10 can quickly and firmly fix the push handle frame to the trolley. The presence of the tightening part 70 can ensure that the connection between the push handle frame and the trolley is firm to avoid loosening or falling off during use.

[0042] Combined with the accompanying drawings Figure 1-Figure 7 As shown, the quick-connect component 10 includes a quick connector 110, which is screwed onto the outer sleeve 20. A quick-connect groove 120 is provided inside the quick connector 110, and the tightening component 70 is detachably installed inside the quick-connect groove 120 to achieve rapid fixation of the quick connector 110 and the trolley.

[0043] For clarification, the outer sleeve 20 can be considered part of the overall structure. Its exterior is threaded, designed to tightly engage the threaded portion of the quick connector 110. The quick connector 110 is a component designed for quick connection and disconnection, typically used in applications requiring frequent assembly and disconnection. The quick connector 110 is internally provided with a quick-connect groove 120, which accommodates a tightening component 70. By inserting the tightening component 70 into the quick-connect groove 120, the quick connector 110 can be securely connected to a trolley or other device. The quick-connect groove 120 is a slot-shaped structure located within the quick connector 110, designed to conveniently accommodate the tightening component 70. This structure provides a specific location for the tightening component 70 to quickly and effectively secure the trolley while also ensuring a secure connection. The tightening component 70 is a detachable component installed within the quick-connect groove 120. The tightening component 70 securely fastens the quick connector 110 to the trolley or other connected component through a rotational mechanical action. This tightening prevents loosening between the connected components and provides sufficient stability.

[0044] Combined with the accompanying drawings Figure 1-Figure 7 As shown, the tightening component 70 includes a first rotary plunger 710 and a second rotary plunger 720. At least two first rotary plungers 710 are provided and are screwed in opposite directions inside the first threaded hole opened at the bottom of the quick connector 110; at least one second rotary plunger 720 is provided and is screwed in the second threaded hole opened in the middle of the quick connector 110.

[0045] It is to be noted that the structural design of the first rotary plunger 710 and the second rotary plunger 720 enables them to achieve the tightening effect on the quick connector 110 by rotation. When the first rotary plunger 710 is tightened, they will squeeze inward, generating friction with the inner wall of the quick connector 110, thereby enhancing the stability of the connection. The second rotary plunger 720 also achieves the tightening of the quick connector 110 by rotation, but its position and function are slightly different from those of the first rotary plunger 710. It is mainly responsible for providing additional fixing force in the middle part of the quick connector 110. This double-layer tightening design not only improves the reliability of the connection, but also allows the user to adjust the degree of tightening according to actual needs to adapt to connecting parts of different sizes and shapes. In addition, the material of the tightening parts 70 is all stainless steel.

[0046] Combined with the accompanying drawings Figure 1-Figure 7 As shown, the adjusting component 30 includes an adjusting sleeve 310, a positioning plunger 320 and a ball head sliding top screw 330. At least two ball head sliding top screws 330 are provided. The adjusting sleeve 310 is fixed to the outer wall of the outer sleeve 20 through the two ball head sliding top screws 330, and the positioning plunger 320 is installed inside the adjusting sleeve 310.

[0047] To explain, the adjustment sleeve 310 is mounted on the outside of the outer sleeve 20 and connected to the outer sleeve 20. The main function of the ball-head sliding screw 330 is to fix the adjustment sleeve 310 so that it is firmly connected to the outer wall of the outer sleeve 20. The ball-head sliding screw 330 is fixed to the outer wall of the outer sleeve 20 by screwing. Due to the presence of the ball head structure, the screw can be adjusted at different angles, ensuring that the adjustment sleeve 310 can be fixed or fine-tuned as needed. The positioning plunger 320 is another important component of the adjustment component 30. By cooperating with the adjustment sleeve 310, it ensures that the adjustment sleeve 310 can be accurately positioned to the desired position during the adjustment process.

[0048] Combined with the accompanying drawings Figure 1-Figure 7 As shown, the retractable component 90 includes an inner sleeve 910, and a telescopic guide groove 920 is provided on the outer wall of the inner sleeve 910. The inner sleeve 910 is inserted into the outer sleeve 20 in cooperation with the telescopic guide groove 920. The inner sleeve 910 is also provided with a first telescopic limit hole 930 and a second telescopic limit hole 940, respectively. The first telescopic limit hole 930 and the second telescopic limit hole 940 are used to cooperate with the positioning plunger 320 for height adjustment.

[0049] To illustrate, the telescopic guide groove 920 of the inner sleeve 910 is designed to allow the inner sleeve 910 to move longitudinally within the outer sleeve 20, thereby realizing the telescopic function of the push handle frame. The position setting of the first telescopic limit hole 930 and the second telescopic limit hole 940 ensures the stability and accuracy of the inner sleeve 910 during the telescopic process. When the positioning plunger 320 is inserted into the corresponding limit hole, the position of the inner sleeve 910 is fixed, which can prevent accidental telescopic expansion and contraction due to external forces during use, and ensure the reliability of the push handle frame in different working conditions. In this way, the push handle frame can be adjusted to three levels of height according to the actual needs of the track geometry detection trolley to adapt to the detection requirements of different tracks.

[0050] Combined with the accompanying drawings Figure 1-Figure 7 As shown, one end of the connector 80 is screwed to the end of the inner sleeve 910 away from the adjustment sleeve 310, and the connecting component 60 is detachably connected to the other end of the connector 80. The connecting component 60 includes a connecting block 610 and a positioning screw 630. At least two positioning screws 630 are provided. The connecting block 610 is fixed to the connector 80 by the two positioning screws 630. The connecting block 610 is also provided with a mounting platform 620 for external electronic equipment.

[0051] To illustrate, the design of the connecting member 60 enables the push handle frame to be flexibly connected to various electronic devices, thereby expanding its functionality. By adjusting the set screw 630, the close fit between the connecting block 610 and the connector 80 can be ensured, thereby ensuring the stability and reliability of the electronic device installation. The setting of the mounting platform 620 provides a stable platform for the electronic device, making it convenient for the operator to install, disassemble and maintain the equipment. In addition, the detachable design of the connecting member 60 makes it possible to replace different types of electronic devices as needed in different detection tasks, greatly improving the applicability and flexibility of the push handle frame.

[0052] Combined with the accompanying drawings Figure 1-Figure 7 As shown, the clamping component 50 includes a clamping block 510 and a locking bolt 520, and the clamping block 510 is screwed to the connecting block 610 through the locking bolt 520. The push handle component 40 includes a push handle tube 420 body, and the push handle tube 420 body is composed of a connecting tube 410 and a push handle tube 420. The connecting tube 410 is clamped between the connecting block 610 and the clamping block 510, and the push handle tube 420 is used for the operator to grab.

[0053] To illustrate, the use of the locking bolt 520 can easily adjust the degree of tightening between the clamping block 510 and the push handle tube 420 to adapt to tracks of different sizes and shapes. The surface of the push handle tube 420 can also be provided with an anti-slip texture to ensure the safety and comfort of the operator when grasping.

[0054] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
