DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-4 The utility model provides a technical solution: a device that is easy to wear and prevents a walkie-talkie from falling off, comprising a casing 1, a fixing seat 2, a fixing clip 3, a pin 5, a torsion spring 4 and a back clip 6. A groove 11 is downwardly provided at the upper end of the back side of the casing 1, and a positioning groove 12 is provided on the inner side of the groove 11.

[0027] The groove 11 is open at the top and the back of the back clip 1 , and the positioning groove 12 is formed on the front side of the inner wall of the groove 11 .

[0028] The fixing clip 3 includes an outer clip 31 and an inner clip 32. The outer clip 31 and the inner clip 32 form an elastic "U" shape. The front side of the inner clip 32 is fixedly connected with a positioning block 34 that can be snapped into the positioning groove 12. A positioning hole 33 is formed through the outer clip 31. Side panels 35 extending backward are provided on both sides of the outer clip 31. Through holes 36 for accommodating the pin 5 are symmetrically formed on the two side panels 35.

[0029] The U-shaped clip formed by the outer clip 31 and the inner clip 32 is elastic and can be opened outward when subjected to force. The outer clip 31 and the inner clip 32 form a U-shaped clip structure with the opening upward inserted into the slot 12 from above. When being stretched open, the positioning block 34 on the front side of the inner clip 32 is inserted into the positioning slot 12, so that the U-shaped clip structure cannot be pulled out of the slot 12, thereby achieving fixation.

[0030] The cross section of the positioning block 34 is a trapezoidal or square structure, or other shapes that are not easy to slide out of the positioning slot 12 .

[0031] The fixing seat 2 includes a base plate 21 , and support plates 23 extending backward are fixedly connected to both sides of the base plate 21 . Pin holes 24 are symmetrically provided on the two support plates 23 . A protrusion 25 that can be snapped into the positioning hole 33 is fixedly connected to the rear side surface of the base plate 21 .

[0032] The projection 25 is shaped so as not to be easily slipped out of the positioning hole 33 .

[0033] The inner clip 32 is placed in the groove 11, the fixing seat 2 is inserted between the outer clip 31 and the inner clip 32 and clamped in the groove 11, the fixing seat 2 opens the outer clip 31 and the inner clip 32 to clamp the positioning block 34 into the positioning groove 12, and the protrusion 25 is embedded in the positioning hole 33 to clamp the fixing seat 2 into the fixing clamp 3.

[0034] During assembly, the U-shaped clip structure formed by the outer clip 31 and the inner clip 32 is opened upward and inserted into the slot 12 from above, and then the fixing seat 2 is inserted into the U-shaped clip, and the outer clip 31 and the inner clip 32 are stretched apart, so that the positioning block 34 is inserted into the slot 12. At this time, the fixing clip 3 cannot be removed from the slot 11. Under the elastic force of the outer clip 31, the protrusion 25 is also inserted into the positioning hole 33, and the fixing seat 2 cannot be removed from the fixing clip 2. At this time, the fixing seat 2 fixes the inner clip 31, and the outer clip 31 fixes the fixing seat 2. The two interact with each other, rely on the elastic force and the clamping structure to be tightly combined together and clamped in the slot 11, and complete the installation of the fixing clip 3 and the fixing seat 2.

[0035] After installation, the side plate 35 and the support plate 23 both extend backward to the rear of the housing 1 for subsequent installation of the pin 5, the torsion spring 4 and the back clamp 6, and the side plate 35 and the support plate 23 are parallel to each other.

[0036] When disassembly is required, the outer clip 31 is bent outward to disengage the protrusion 25 from the positioning hole 33, so that the fixing seat 2 is out of contact with the outer clip 31 and can be pulled outward. After the fixing seat 2 is pulled outward, the inner clip is no longer subjected to force, and the positioning block 34 can be disengaged from the slot 12. In this way, the fixing clip 3 can also be taken out from the groove 11 to complete the disassembly.

[0037] Two axial holes are provided on the back clamp 6, and the pin shaft 5 passes through the pin holes 24 and the through holes 36 on the two support plates 23 and the two side plates 35 and the axial hole on the back clamp 6 in sequence to complete the installation. The torsion spring 4 is sleeved on the pin shaft 5 and is located between the back clamp 6 and the outer clamp 31.

[0038] After the fixing clamp 3 and the fixing seat 2 are installed, the supporting structure of the back clamp 6 is formed. At this time, the torsion spring 4 is placed between the two side plates 35, and then the back clamp 6 is placed until installation. At this time, the shaft hole, the through hole 36, the pin hole 24 and the center hole of the torsion spring 4 are in the same straight line. The pin shaft 5 is passed through the above structure in turn to connect the back clamp 6 to the supporting structure, and the elastic force of the torsion spring 4 is relied on to realize the restoration of the back clamp after flipping.

[0039] Both sides of the inner wall of the groove 11 are provided with raised pressure strips 13 , and both sides of the base plate 21 are provided with raised clamping strips 22 . When the fixing seat 2 is inserted between the outer clamping piece 31 and the inner clamping piece 32 , the clamping strips 22 are pressed by the pressure strips 13 .

[0040] After the fixing seat 2 is inserted into the fixing clamp 3, the two clamping strips 22 are respectively inserted into the inner side of the pressure strip 13 and are pressed against the front side of the inner wall of the groove 11. The pressure strip 13 guides the movement of the clamping strip 22 on the one hand, and can press the clamping strip 22 on the other hand, so that the base plate 21 of the fixing seat 2 maintains the inward pressure to press the inner clip 32. Otherwise, the inner clip 32 is not subjected to force, and the positioning block 34 cannot be clamped in the slot 12.

[0041] The outer clip 31 , the inner clip 32 and the two side plates 35 are integrally formed, and the width of the outer clip 31 is smaller than the distance between the two support plates 23 . That is, the outer clip 31 and the two side plates 35 are both located between the two support plates 23 .

[0042] The fixing clip 3 may be made of plastic material or elastic metal material.

[0043] A through hole 36 on a side plate 35 extends forward to form a groove-shaped structure, and an elastic limiting plate 37 is provided at one end of the inner cavity of the groove-shaped structure. A recessed annular positioning groove 51 is provided on the surface of the pin shaft 5. The pin shaft 5 passes through the through hole 36, and the end of the limiting plate 37 is embedded in the annular positioning groove 51 to prevent the pin shaft 5 from falling off.

[0044] During the insertion process of the pin 5, the limit plate 37 is slightly deformed so that the pin 5 can be inserted until the annular positioning groove 51 moves to the position corresponding to the limit plate 37. The limit plate 37 obtains space for restoration and restores its deformation under the action of elastic force and is stuck in the annular positioning groove 51. At this time, without deliberately pulling the pin 5, the pin 5 cannot move axially and will not fall off, thereby ensuring the stable connection between the back clamp 6 and the supporting structure. When the back clamp 6 needs to be removed, the back clamp 6 can be removed by directly pulling out the pin 5 with force or pressing the limit plate 37 to deform it and then pulling out the pin 5.

[0045] Mounting plates 7 are provided on both sides of the back clamp 6, and axial holes are opened on the mounting plates 7. The distance between the two mounting plates 7 is greater than the distance between the two support plates 23. The two mounting plates 7 are located on the outsides of the two support plates 23. Therefore, on one side, the order from the outside to the inside is the mounting plate 7, the support plate 23 and the side plate 35.

[0046] Please refer to Figure 5-6 The outer side of the support plate 21 is an arc surface, and a clamping position 26 is arranged on the arc surface. A limiting block is arranged on the inner side surface of the back clip 6. When the back clip 6 is turned over, the limiting block is limited in rotation angle by the clamping position 26.

[0047] The bottom of the back clip 6 always tends to approach the housing 1 under the action of the torsion spring 4, and the clamping position 26 clamps the limit block, and cooperates with the elastic force of the torsion spring 4 to allow the back clip 6 to rotate within a certain angle range. When it rotates inward to the maximum angle, there is always a certain gap between the bottom of the back clip 4 and the housing 1, which is convenient for adding to a pocket or a belt.
