An installation structure is provided at the front end of the connecting frame for mounting construction equipment.

[0004] Based on the above technical features, the problem is that most of the external attachments on existing safety helmets are attached to the front of the brim, which causes the center of gravity of the safety helmet to shift forward, thus affecting the worker's ability to raise their head and increasing the load on the front of the worker's head; at the same time, the mounting structure for attaching external attachments is mostly attached to the helmet itself, which increases the weight of the helmet and the load on the worker's head, making it unsuitable for wearing.

[0005] Therefore, it is necessary to solve the above problems by using a helmet external attachment installation structure. Utility Model Content

[0020] This utility model provides, for example Figures 1 to 4 The diagram shows an external helmet mounting structure, including a mounting base 2 fixed to the helmet 1, with the mounting base 2 located at the part of the helmet 1 corresponding to the ears.

[0021] A retainer 5 is detachably mounted on the mounting base 2 via a disassembly assembly. The retainer 5 is rotatably engaged with the mounting base 2. In this example, the mounting base 2 is disc-shaped and integrally formed with the safety helmet 1, while the retainer 5 is cylindrical. The mounting base 2 and the retainer 5 are coaxially opposed, and a clearance groove is formed axially at the end of the retainer 5 near the mounting base 2. The clearance groove matches the mounting base 2, and the retainer 5 is rotatably engaged with the mounting base 2 through the clearance groove.

[0022] The assembly / disassembly component includes two cantilevered clips 4 fixed to the mounting base 2. The two cantilevered clips 4 are symmetrically arranged, and each cantilevered clip 4 is an L-shaped clip. The clip heads of both cantilevered clips 4 are provided with a transmission ramp, and the two transmission ramps slide against the clip base 5.

[0023] A clearance through hole is formed axially inside the card holder 5. The opening of the clearance through hole near the mounting base 2 communicates with the clearance groove, and the diameter of the clearance through hole decreases as it moves away from the mounting base 2. Both cantilevered buckles 4 pass through the clearance through hole and are engaged with the card holder 5.

[0024] An adjustable limit component is provided between the card holder 5 and the mounting base 2. The adjustable limit component cooperates with the card holder 5 to adjust the rotation angle of the card holder 5.

[0025] The adjustable limiting assembly includes a first retaining ring 3, a second retaining ring 6, and a spring 8. The first retaining ring 3 is coaxially fixed to the mounting base 2, and two cantilevered buckles 4 pass through the first retaining ring 3.

[0026] An annular groove is formed along the axial direction inside the card holder 5. The end of the annular groove near the mounting base 2 is connected to the clearance groove. The clearance perforation is formed along the central axis of the annular groove.

[0027] The second retaining ring 6 and the spring 8 are both coaxially arranged in the annular groove. The second retaining ring 6 and the retaining seat 5 are slidably connected and simultaneously driven by a connecting piece. The spring 8 is arranged along the sliding direction of the second retaining ring 6, and one end of the spring 8 is fixedly connected to the second retaining ring 6, while the other end is fixedly connected to the retaining seat 5.

[0028] The connector includes a connecting block 7, which is T-shaped. The connecting block 7 is arranged radially along the second retaining ring 6 and fixed to the outer wall of the second retaining ring 6. A connecting groove corresponding to and matching the connecting block 7 is formed axially on the curved inner wall of the annular groove, and the connecting block 7 and the connecting groove are in a limiting sliding fit.

[0029] The first retaining ring 3 and the second retaining ring 6 are coaxially opposite each other, and a ring of retaining teeth is fixedly provided around the circumference at the near ends of the first retaining ring 3 and the second retaining ring 6. The retaining teeth on the first retaining ring 3 mesh with the retaining teeth on the second retaining ring 6.

[0030] A mounting plate 9 is fixedly mounted on the card holder 5, and a clamping mechanism for fixing external devices is mounted on the mounting plate 9. The clamping mechanism includes two clamping blocks 10, one of which is fixed on the mounting plate 9, and the other is slidably mounted on the mounting plate 9.

[0031] A driving component is installed on the mounting plate 9. A clamping block 10 slidably disposed on the mounting plate 9 is connected to the driving component to drive the clamping block 10 to slide closer to or away from the clamping block 10 fixed on the mounting plate 9.

[0032] The driving component includes a threaded rod 11, and a guide groove is formed on the mounting plate 9. The threaded rod 11 passes through the guide groove and is rotatably connected to the mounting plate 9. The clamping block 10, which is slidably disposed on the mounting plate 9, is limited and slidably engaged with the guide groove. The threaded rod 11 passes through the clamping block 10, which is limited and slidably engaged with the guide groove, and is threadedly connected to the clamping block 10.

[0033] The external device is located between two clamping blocks 10, and the two clamping blocks 10 hold and fix the external device.

[0034] Working principle: When it is necessary to install the external device onto the safety helmet 1, first install the mounting bracket 5 onto the mounting base 2. During the installation of the mounting bracket 5 onto the mounting base 2, align the clearance groove on the mounting bracket 5 with the mounting base 2, and then push the mounting bracket 5 to move closer to the mounting base 2.

[0035] As the mounting base 5 moves closer to the mounting base 2, the two cantilever latches 4 pass through the clearance groove and clearance through hole in sequence. When the two cantilever latches 4 move to a position where the clearance through hole is away from the opening of the mounting base 2, the mounting base 2 pushes the two cantilever latches 4 to bend and move closer. After the two cantilever latches 4 pass through the clearance through hole, the two cantilever latches 4 spring back and move closer to engage with the mounting base 5.

[0036] At the same time, the card holder 5 pushes the second retaining ring 6 to move closer to the first retaining ring 3 via the spring 8, and the retaining teeth on the second retaining ring 6 move closer to the retaining teeth on the first retaining ring 3. When the retaining teeth on the second retaining ring 6 contact and engage with the retaining teeth on the first retaining ring 3, the spring 8 is compressed, and at the same time, the two cantilevered buckles 4 have passed through the clearance holes and engaged with the card holder 5.

[0037] Next, place the external device between the two clamping blocks 10, and then rotate the threaded rod 11. The threaded rod 11 pushes the connected clamping block 10 to slide closer to the other clamping block 10 until the two clamping blocks 10 clamp the external device.

[0038] Finally, put on the safety helmet 1. When it is necessary to adjust the angle of the external equipment, simply rotate the mounting bracket 5. At this time, the mounting bracket 5 drives the connecting block 7 to rotate, and the connecting block 7 drives the second retaining ring 6 to rotate. The second retaining ring 6 slides against the first retaining ring 3, and the retaining teeth on the first retaining ring 3 push the retaining teeth on the second retaining ring 6 to reciprocate away from the mounting base 2. As the second retaining ring 6 reciprocates and slides away from the mounting base 2, the second retaining ring 6 reciprocates and compresses the spring 8. At the same time, the spring 8 reciprocates and extends, and pushes the second retaining ring 6 to reciprocate and move away from the mounting base 2, and the retaining teeth on the second retaining ring 6 reciprocate and engage with the retaining teeth on the first retaining ring 3.

[0039] Once adjusted to the desired angle, the teeth on the second retaining ring 6 engage with the teeth on the first retaining ring 3.

[0040] When it is necessary to remove the mounting base 5, simply push the two cantilevered clips 4 together to bend them closer. After that, the two cantilevered clips 4 will disengage from the mounting base 5, and the mounting base 5 will move away from the mounting base 2 under the action of the spring force of the spring 8.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
