Description

Technical Field

[0001] The utility model relates to the technical field of compasses, in particular to a fixing device for a compass. Background Art

[0002] Compass, as an important navigation and positioning tool, is widely used in geographical exploration, forest survey, navigation, construction and other fields. Its core function is to indicate the geomagnetic direction through the magnetic needle, so as to determine the direction. However, in actual use, the stability and accuracy of the compass are often affected by environmental factors, especially in complex terrain or dynamic environment. The fixation and stable use of the compass has become a problem to be solved urgently.

[0003] The patent with publication number CN214748015U proposes a compass device with a fixed bracket, including a compass, a fixed plate, and a bracket device. The compass is installed on the fixed plate, and the fixed plate is movably installed above the bracket device. The utility model provides a compass device with a fixed bracket. The limit block below the fixed seat is fixed to the bottom of the connecting block by four fixing bolts, and the limit block is embedded above the fixed seat, so that the entire fixed seat can be fixed above the bracket device, and the connecting block and the limit block can be rotated in the fixed seat through the first fixed bearing and the second fixed bearing for positioning and use, which is convenient for the staff to adjust the compass, and the positioning is convenient and accurate, and the operation steps are simple and efficient.

[0004] As described in the above patent, although the traditional compass fixing device, such as the tripod bracket, can fix the compass to a certain extent, it still has many shortcomings in practical applications. For example, the traditional fixing device is often complex in structure and cumbersome to operate. It is specifically reflected in the assembly and fixing of multiple groups of bolts, which requires relevant personnel to assemble them in sequence, which is time-consuming and labor-intensive, and is not conducive to rapid deployment and portable use. To this end, the utility model provides a compass fixing device. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a compass fixing device, which solves the problem that traditional compass fixing devices are often complex in structure and cumbersome in operation. Specifically, the fixing devices require multiple sets of bolts for assembly and fixing, which requires relevant personnel to assemble them one by one, is time-consuming and labor-intensive, and is not conducive to rapid deployment and portable use.

[0006] To achieve the above objectives, the utility model is implemented through the following technical solutions: a compass fixing device, including a door frame, a compass body is detachably mounted on the upper end of the door frame, and a fixing mechanism is provided on the door frame for fixing the compass body, and the fixing mechanism includes:

[0007] Four sets of clamping components are arranged in a circular array on the upper part of the portal frame, including a double-headed shaft block rotatably mounted on the upper part of the portal frame, a fixed pressure block is fixedly connected to the upper part of the double-headed shaft block, and a slot rod is fixedly connected to the lower part of the double-headed shaft block;

[0008] The driving positioning component is arranged on the inner side of the door frame and is used to horizontally position the clamping component.

[0009] Preferably, the driving and positioning assembly comprises a sleeve fixedly mounted on the bottom wall of the upper portion of the portal frame, a rotating ring is horizontally clamped on the inner wall of the sleeve, and a threaded rotating rod is welded on the inner wall of the rotating ring.

[0010] Preferably, a cross block is threadedly screwed on the outer wall of the threaded rotating rod, four groups of track rods are fixed to the outer wall array of the sleeve, and sliding blocks are slidably installed on the four groups of track rods, and a transmission rod is movably installed between the cross block and the sliding block.

[0011] Preferably, a positioning strip is fixed to one side of the sliding block, and a positioning slot for mating and plugging with the positioning strip is provided on the side of the slot rod facing the positioning strip.

[0012] Preferably, a pre-positioning strip is rotatably mounted on one side of the double-headed shaft block, a slot block corresponding to the pre-positioning strip is fixed on the outer wall of the edge of the portal frame, and a slot for the pre-positioning strip to be inserted is provided on the slot block.

[0013] Preferably, a triangular support frame is fixed to the lower end of the portal frame, and is used to provide three-point support for the bottom of the portal frame.

[0014] Beneficial Effects

[0015] The utility model provides a compass fixing device. Compared with the prior art, it has the following beneficial effects:

[0016] (1) The fixing device of the compass is designed with a fixing mechanism. The double-headed shaft block on the periphery is rotated so that the fixing pressure block presses the compass. Then, the threaded rotary rod at the lower end of the sleeve is rotated to engage with the cross block through threads, so that the cross block can rise upward, thereby pushing the sliding block to slide along the track rod in a directional manner through the transmission rod. The track rod drives the positioning strip to be inserted into the slot of the slot rod, thereby completing the positioning and fixing of the compass. The installation is convenient. Similarly, the positioning strip and the slot rod can be quickly separated by rotating the threaded rotary rod in the opposite direction.

[0017] (2) The fixing device of the compass is designed with a pre-positioning strip and a slot block. When the peripheral double-headed shaft block is rotated so that the fixed pressure block presses the compass, the pre-positioning strip naturally falls into the slot block to form a preliminary positioning for the slot rod, which is convenient for subsequent docking and installation with the slot rod.
