[0016] like Figures 1-5 As shown, the quick-fixing device for the test vehicle testing equipment of this utility model includes a locking component 1 and a locking block 2. The locking component 1 is fixed to the test equipment, and the locking block 2 is fixed to the mounting hole on the test vehicle's bottom plate. The locking component 1 includes a housing 11 and a bolt shaft 13 and a spring 15 installed inside the housing 11. A transverse bolt handle 16 is provided on the upper part of the bolt shaft 13. The bolt handle 16 is set in the track groove 112 of the housing 11 and can slide along the track groove 112. The spring 15 is sleeved on the bolt shaft 13. The upper end of the spring 15 abuts against the bolt handle 16, and the lower end of the spring 15 abuts against the housing 11. The lower end of the bolt shaft 13 passes through the housing 11 and is connected to the locking pin 14. The locking block 2 is provided with a through hole 21 through which the locking pin 14 can pass. The bottom of the locking block 2 is provided with a slot 22 that matches the locking pin 14. By pressing down the bolt shaft 13 with the bolt handle 16 and driving the bolt shaft 13 to rotate, the locking pin 14 passes through the through hole 21 and is locked into the slot 22 at the bottom of the locking block 2, so as to fix the test equipment.

[0017] Specifically, such as Figure 1 , Figure 2 and Figure 5 As shown, the housing 11 is welded together from a stainless steel square tube 111, an upper sealing plate 114, and a lower sealing plate 113. The lower sealing plate 113 has a through hole through which the bolt shaft 13 can pass. In the unlocked state, under the elastic force of the spring 15, the top of the bolt shaft 13 abuts against the upper sealing plate 114.

[0018] A mounting plate 12 is provided on one side of the housing 11. The mounting plate 12 is connected to the housing 11 by welding. The mounting plate 12 is provided with multiple fixing holes. The locking member 1 is fixed to the test equipment by screws or rivets.

[0019] The locking pin 14 is laterally positioned at the bottom of the bolt shaft 13. Specifically, the bottom of the bolt shaft 13 has a locking pin hole 131 that matches the locking pin 14, and the locking pin 14 passes through the locking pin hole 131 to connect with the bolt shaft 13. The length of the locking pin 14 is greater than the diameter of the through hole on the lower sealing plate 113.

[0020] The track groove 112 has a hook-shaped structure. In the locked state, the bolt is engaged in the limiting groove at the end of the track groove 112 (e.g., Figure 3 and Figure 4 (As shown).

[0021] like Figures 1-4As shown, the locking block 2 is machined from round steel, with a through hole 21 running from top to bottom through it. The slotted hole 22 at the bottom of the locking block 2 has a certain depth to better accommodate the locking pin 14. A cross groove is formed between the slotted hole 22 at the bottom of the locking block 2 and the through hole 21 (as shown). Figure 2 and Figure 4 (As shown).

[0022] In use, two locking pieces 1 are installed on the test equipment that needs to be fixed. Mounting holes are drilled at the fixed positions on the test vehicle floor, and locking blocks 2 are welded to the drilled mounting holes on the test vehicle floor. When locking the test equipment, first move the test equipment to the fixed position in the carriage, and align the locking pin 14 of the locking piece 1 installed on the test equipment with the slotted hole 21 of the locking block 2. Press down on the bolt handle 16 with your foot to move the bolt shaft 13 downwards, allowing the locking pin 14 to pass through the slotted hole 21 of the locking block 2. Then, rotate the bolt handle 16 counterclockwise 90° and lift your foot. The locking pin 14 will be engaged in the slotted hole 22 under the elastic force of the spring 15. At this time, the bolt handle 16 is engaged in the end limiting groove of the track groove 112 (e.g., ...). Figure 3 and Figure 4 As shown, because the spring 15 has sufficient elasticity, even if the vehicle is traveling on a relatively bumpy road, the locking pin 14 will not come out of the slot 22, thus the test equipment is firmly fixed to the floor of the vehicle.
