DETAILED DESCRIPTION
[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0020] Embodiment: A handbrake handle force test trigger device, such as Figure 1-Figure 5 As shown, it includes a finger ring 2, a positioning component 4 installed on the finger ring 2, and a handle dynamometer 3 installed on the positioning component 4; wherein, a guide groove 202 for the positioning component 4 to slide is opened on one side of the finger ring 2, and side grooves 204 for the positioning component 4 to slide are opened on both sides of the guide groove 202.
[0021] The positioning assembly 4 includes a positioning cylinder 401 , a square tube 404 symmetrically provided on the outer side of the positioning cylinder 401 and slidingly arranged in the side groove 204 , an opening 402 is opened on the outer side of the positioning cylinder 401 , and a shift block 405 is slidably arranged in the square tube 404 .
[0022] The handle dynamometer 3 includes a collecting end 301 embedded in the positioning cylinder 401 . The collecting end 301 is provided with a signal output end 302 penetrating the finger ring 2 . A through hole 207 communicating with the guide groove 202 is provided on the lower surface of the finger ring 2 .
[0023] like Figure 4 As shown, a telescopic rod 406 is fixedly connected to one side of the shift block 405. One end of the telescopic rod 406 is fixedly connected to the bottom of the inner cavity of the square tube 404. A spring 407 is sleeved on the outer side of the telescopic rod 406. Limit blocks 409 are provided on both sides of the shift block 405 adjacent to the telescopic rod 406. Limit grooves 206 for the limit blocks 409 to engage are formed on both sides of the inner cavity of the side groove 204. Anti-slip grooves 410 are provided on the side of the shift block 405 opposite the telescopic rod 406. The anti-slip grooves 410 facilitate pushing the shift block 405, thereby causing the limit block 409 to slide along the straight groove 205. After sliding to the desired position, the elastic potential energy of the spring 407 causes the limit block 409 to return to the limit groove 206, thereby limiting the position of the positioning cylinder 401 and improving the stability of the handle dynamometer 3.
[0024] Rectangular holes 408 are provided on both sides of the square tube 404 for the sliding positioning of the stop blocks 409. Straight grooves 205 are provided on both sides of the inner cavity of the side groove 204, interconnecting with multiple sets of stop grooves 206. The multiple sets of stop grooves 206 are arranged at equal intervals. These multiple sets of stop grooves 206 facilitate the positioning of the positioning cylinder 401 after adjustment, thereby ensuring the stability of the handle dynamometer 3 after adjustment. This makes operation simple and convenient, and enhances practicality.
[0025] like Figure 2 and Figure 4 As shown, a slide groove 203 is formed on one side of the inner cavity of the guide groove 202, and a slider 403 is fixedly connected to the bottom of the positioning cylinder 401 and is slidably arranged in the slide groove 203. The sliding of the slider 403 in the slide groove 203 improves the stability of the moving position of the positioning cylinder 401, thereby facilitating the detection of force at different positions of the handle dynamometer 3, thereby improving the accuracy of the braking performance detection.
[0026] like Figure 1 As shown, a plurality of anti-slip bumps 201 are provided on one side of the inner cavity of the finger ring 2. The finger ring 2 is arranged in a D shape, and an anti-slip pad is provided on one side of the finger ring 2. The finger ring 2 facilitates the staff to fix the handle force gauge 3, thereby improving the stability of the handle force gauge 3 during the handbrake handle force test.
[0027] One side of the finger ring 2 is in contact with the outer side of the handbrake handle 1, and one side of the collecting end 301 protrudes 1-2 mm from the opening of the positioning tube 401. The handle force gauge 3 is a miniature pressure sensor, such as the DSHW-108 miniature pressure sensor. The protruding part of the collecting end 301 of the handle force gauge 3 is in contact with the handbrake handle 1, thereby facilitating the test of the handbrake handle strength.
[0028] During use, the staff embeds the collecting end 301 of the handle force gauge 3 in the positioning cylinder 401, and connects the signal output end 302 to the external display device through the through hole 207, and compresses the spring 407 on the telescopic rod 406 by pressing the dial block 405, so that the limit block 409 moves along the limit groove 206 to the straight groove 205, which is convenient for adjusting the position of the positioning cylinder 401; the staff passes the finger through the finger ring 2 and holds the handbrake handle 1 together with the finger ring 2, and applies tension to the handbrake handle 1, thereby facilitating the braking performance test of the forklift. The collecting end 301 of the handle force gauge 3 is in contact with the handbrake handle 1, thereby improving the accuracy of the force test.
[0029] As a preference, Figure 1 As shown, a handle cover 5 can be mounted on the handbrake handle 1 to increase friction and prevent hand slippage. On the other hand, the end surface of the handle cover 5 can be used to determine the position of the finger ring 2.
[0030] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
