A fixture body 13 is rotatably connected to one side of the support rod 121. The mounting bracket 1 is provided with an adjustment mechanism, which adjusts the detection surface of the static arc contact. The adjustment mechanism includes a transmission screw 111 fixedly connected to one side of the knob 11, and a sliding block 112 is threadedly connected to the transmission screw 111.
[0031] The present invention will be further described below with reference to the embodiments.
[0032] Example 1:
[0033] To address the problem that existing testing fixtures generally have limited functionality, often lacking a flipping function during contact clamping, and requiring frequent manipulation of the testing structure for multi-directional contact testing, thus impacting work efficiency, this embodiment discloses the following technical solution, specifically as follows: Figures 1-4As shown, the sliding block 112 is slidably connected inside the mounting bracket 1. A heat sink 113 is fixedly connected to the top of the sliding block 112. A geared motor 114 is fixedly connected inside the heat sink 113. The output end of the geared motor 114 is fixedly connected to the rotating disk 12. Two sets of support rods 121 are provided. A knob 122 is rotatably connected to one side of the support rod 121. A connecting shaft 123 is fixedly connected to one side of the knob 122. The connecting shaft 123 is fixedly connected to the clamp body 13. A slot group 124 is opened on the outer side of the connecting shaft 123. A transmission block 125 is slidably connected to one side of the support rod 121. The bottom end of the transmission block 125 is fixedly connected to... A spring rod 126 is fixedly connected at one end to the inside of a support rod 121. A locking block assembly 127 is fixedly connected to the top of a transmission block 125, and the locking block assembly 127 slides in conjunction with a locking groove assembly 124. A knob 131 is rotatably connected to the fixture body 13, and a threaded screw 132 is fixedly connected to the bottom of the knob 131. Both ends of the threaded screw 132 are threaded with clamping blocks 133. When it is necessary to fix the static arc contact, the static arc contact can be installed inside the fixture body 13. By rotating the knob 131, the knob 131 drives the threaded screw 132 to rotate, thereby causing the two sets of clamping blocks 133 to rotate. The movable clamping block 133 can clamp the stationary arc contact, and the clamped stationary arc contact is detected by the detection mechanism. When it is necessary to flip the stationary arc contact, the transmission block 125 located on the support rod 121 can be moved. The transmission block 125 drives the locking block assembly 127 to move, thereby separating the locking block assembly 127 from the connecting shaft 123. At this time, the clamp body 13 can be rotated by turning the knob 122. When it is rotated to the appropriate position, the transmission block 125 is released. Under the action of the spring rod 126, the locking block assembly 127 moves and engages inside the locking slot assembly 124, which fixes the connecting shaft 123, thereby achieving the desired effect. To improve the flipping detection effect, the operator can also rotate knob 11, which drives the transmission screw 111 to rotate, thereby moving the sliding block 112. The sliding block 112 moves the rotating disk 12 through the heat sink box 113. At this time, the distance between the stationary arc contact and the detection structure can be adjusted to facilitate better detection of the stationary arc contact. The operator can also start the reduction motor 114, which drives the rotating disk 12 to rotate, thereby rotating the support rod 121. This allows for further adjustment of the detection position of the stationary arc contact, enabling the operator to easily change the detection position of the stationary arc contact and improving work efficiency.
[0034] Example 2:
[0035] To address the problem that existing testing fixtures often lack effective protective mechanisms when testing stationary arc contacts, potentially leading to the contact falling off during use, this embodiment discloses the following technical solution, specifically as follows: Figure 4 and Figure 5 As shown, the fixture body 13 is also provided with a mounting groove 134. A magnet 135 is fixedly connected inside the mounting groove 134, and a baffle 136 is slidably connected inside the mounting groove 134. A toggle lever 137 is fixedly connected to both the upper and lower sides of the baffle 136. When the stationary arc contact is fixed by rotating the knob 131, the toggle lever 137 located inside the mounting groove 134 can be moved. The toggle lever 137 drives the baffle 136 to move, thereby reducing the opening on one side of the fixture body 13, which can provide a certain protective effect for the stationary arc contact. When the stationary arc contact needs to be removed after the test, the toggle lever 137 is moved so that the baffle 136 and the magnet 135 are in contact, which can fix the baffle 136. This achieves the function of protecting the stationary arc contact during the test and improves the efficiency of use.
