Detailed Implementation

[0025] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0026] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0027] Reference Figures 1-6 An extension rod for a road marking measurement device includes a main measuring device 1. The main measuring device 1 has buttons on its surface for controlling it. These buttons are connected to signal contacts 5 via wires. Signal contacts 5 are located on the top of the main measuring device 1. An extension rod module 2 is fixed to the top of the main measuring device 1, and a handle 201 is fixed to the top of the extension rod module 2. A button 202 is located at one end of the handle 201 near the extension rod module 2. By installing the extension rod module 2 on the top of the main measuring device 1, the main measuring device 1 has a suitable and compatible extension rod. This eliminates the need for operators to directly hold the main measuring device 1 for measurement, reducing operator fatigue and safety hazards, as well as measurement errors and increasing efficiency. This method is simple in structure, low in cost, and highly reliable, making it suitable for large-scale engineering applications.

[0028] An adapter block 204 is fixed to the bottom end of the extension rod module 2 near the spring clip block 203 by a secondary bolt group 205. The surface of the adapter block 204 and the bottom end of the extension rod module 2 are provided with mounting holes. The measuring main device 1 and the extension rod module 2 are fixed by a quick-connect knob 206. Through the mounting hole and the quick-connect knob 206, the operator can fix the measuring main device 1 and the extension rod module 2 by inserting the quick-connect knob 206 into the mounting hole. When transportation or storage is required, the measuring main device 1 and the extension rod module 2 can be disassembled for storage or transportation by pulling out the quick-connect knob 206, which is convenient for the operator to transport and install.

[0029] A spring clip 203 is fixed to one side of the inclined surface of the adapter block 204 by the main bolt assembly 207. A contact spring 3 is fixed to the surface of the spring clip 203. One end of the contact spring 3 contacts and communicates with the surface of the signal contact 5. A wire is welded to the other end of the contact spring 3. The wire passes through the extension rod module 2 and the handle 201 and is connected to the button 202. It is connected to the original button of the measuring main device 1 through the signal contact 5. The contact spring 3 of the spring clip 203 contacts and communicates with the signal contact 5 and is connected to the button 202 through the wire. This allows the operator to hold the handle 201 while conveniently controlling the button 202 to operate the measuring main device 1, which is ergonomic and improves the user experience.

[0030] An insulating pressure plate 4 is fixed on the side of the contact spring 3 near the adapter block 204, and the contact spring 3 is insulated around the periphery by the insulating pressure plate 4.

[0031] The extension rod module 2 includes an outer rectangular rod 2001, with a rectangular groove 2002 on the inner wall of the outer rectangular rod 2001. An inner rod 2003 is slidably connected to the inner wall of the rectangular groove 2002. An end block 2004 is fixed to the top of the inner rod 2003, and a handle 201 is fixed to the top of the end block 2004. Through the sliding connection between the outer rectangular rod 2001 and the inner rod 2003, the operator can adjust the total length of the extension rod module 2 according to their own situation. This allows the extension rod module 2 to be adjusted according to the equipment height, the operator's height, walking status, and measurement status, making it convenient for different operators or different usage environments.

[0032] Trapezoidal members 6 are fixed on both sides of the inner rod 2003, and limiting trapezoidal grooves 601 are opened on both sides of the inner wall of the outer rod 2001. The inner wall of the limiting trapezoidal groove 601 is slidably connected to the surface of the trapezoidal member 6. Through the sliding cooperation between the trapezoidal member 6 and the limiting trapezoidal groove 601, the sliding path of the inner rod 2003 in the outer rod 2001 is limited, preventing abnormal wear caused by its deviation and improving its service life.

[0033] The inner rod 2003 has multiple slots 8 linearly arranged on one side, and the outer rod 2001 has an installation groove on its inner wall. An insert 801 is slidably connected to the inner wall of the installation groove. A connecting rod 802 is fixed to one end of the insert 801 away from the inner rod 2003. An end piece 803 is fixed to one end of the connecting rod 802. A lifting ring 804 is fixed to one end of the end piece 803. A return spring 805 is fixed to one end of the insert 801. One end of the return spring 805 is fixed to the inner wall of the installation groove. Through the cooperation between the insert 801 and the slot 8, the operator can provide force feedback to the user when changing the length of the extension rod module 2. At the same time, it assists in the cooperation and fixation between the inner rod 2003 and the outer rod 2001 to prevent the length of the extension rod module 2 from changing.

[0034] Both the top and bottom of the trapezoidal part 6 are glued with oval pads 7. The oval pads 7 provide a buffering effect to prevent the trapezoidal part 6 from colliding with the two ends of the limiting groove 601, thus preventing wear and damage and increasing the service life of both.

[0035] The working principle of this utility model is as follows: When transporting the equipment, the main measuring device 1 and the extension rod module 2 can be disassembled for easy storage and transportation, increasing the utilization of transport space. When the operator needs to use it, the adapter block 204 is aligned with the signal contact 5 on the top of the main measuring device 1, so that the contact spring 3 contacts the signal contact 5. Due to the inclined surface of the adapter block 204, the contact surface is ensured to be parallel to the surface where the signal contact 5 is located. The operator inserts the quick-connect knob 206 into the mounting hole to fix the main measuring device 1 and the extension rod module 2 together by a snap or thread, so that the operator can control the main measuring device 1 through the handle 201 and the button 202, eliminating the need for the operator to bend the main measuring device 1 when using it. The extension rod module 2 can be adjusted by using a waist or climbing to reduce work fatigue and safety hazards, as well as measurement errors and increase efficiency. When the worker needs to adjust the length of the extension rod module 2, he can grab the handle 201 with one hand and pinch the lifting ring 804 with the other hand to pull the end piece 803, connecting rod 802 and insert 801 outward, so that the insert 801 leaves the inner wall of the groove 8. The outer rod 2001 and inner rod 2003 can slide freely. When the worker slides the two to the appropriate position, he can release the lifting ring 804, so that the insert 801 is embedded in the corresponding groove 8, so that the outer rod 2001 and inner rod 2003 are re-fixed and provide force feedback to the user. The trapezoidal part 6 and the limiting trapezoidal groove 601 cooperate and slide, limiting the sliding path of the inner rod 2003 in the outer rod 2001.
