Description

Technical Field

[0001] This utility model relates to a back clip structure, specifically to a back clip structure for a walkie-talkie. Background Technology

[0002] Walkie-talkies are generally designed with a clip-on structure. By assembling the walkie-talkie with the clip, the clip can be fastened to the edge of a belt, clothing, or trouser pocket, allowing the walkie-talkie to be worn by the user for convenient carrying, real-time communication, and listening. Currently, most walkie-talkie clip structures use a fixed installation between the walkie-talkie and the clip. However, when removing the walkie-talkie from the clip, because the walkie-talkie and clip are tightly fixed to prevent the walkie-talkie from falling off, a considerable amount of external force is required to detach the walkie-talkie from the clip, making disassembly rather cumbersome, although it saves time and effort.

[0003] In view of this, this application has conducted in-depth research on this basis, resulting in this case. Utility Model Content

[0004] The purpose of this utility model is to provide a back clip structure for walkie-talkies that is easy to assemble and disassemble, saves time and effort, and is not easy to loosen during installation.

[0005] To achieve the above objectives, the solution of this utility model is:

[0006] A back clip structure for a walkie-talkie includes a back clip and a mounting / unmounting assembly. The side where the back clip and the walkie-talkie housing mate is designated as the mating side, and the side where the back clip and the housing are opposite to each other is designated as the unmounting side. The mounting / unmounting assembly includes a mounting block installed on the mating side of the housing and an insertion block installed on the mating side of the mounting block. The back clip has a back clip groove for inserting the insertion block, with the opening of the back clip groove facing the mating side of the mounting block. The mating side of the back clip has a snap-fit ​​protrusion. The mounting block has a snap-fit ​​groove corresponding to the snap-fit ​​protrusion, and the mating side of the back clip has snap-fit ​​seams on both sides corresponding to the snap-fit ​​protrusion. Both snap-fit ​​seams are connected to the back clip groove. The mounting block has snap-fit ​​protrusions corresponding to the positions of the two snap-fit ​​seams. When the walkie-talkie is removed from the back clip, the housing rotates relative to the back clip to disengage the snap-fit ​​protrusion from the snap-fit ​​groove and to disengage the two snap-fit ​​protrusions from their corresponding snap-fit ​​seams.

[0007] The insertion block has two opposing mounting slots on its opposite side, and the mounting mating block has mounting protrusions on its mating side corresponding to the two mounting slots.

[0008] The insertion block is T-shaped, and the large head of the insertion block is inserted into the back clip groove.

[0009] With the hinge position of the back clip as the upper side of the back clip and the opposite side as the lower side of the back clip, limit grooves are respectively opened on the two opposite side walls of the back clip groove. The two limit grooves are arranged in the vertical direction, and the thickness of the two limit grooves gradually decreases from bottom to top. The two limit grooves are respectively matched with the insertion block for limiting.

[0010] The housing has a housing groove on the mating side, and slots are provided on both sides of the housing groove. The mounting block has a mating slot on the opposite side corresponding to the two slots.

[0011] The mounting block has a mounting groove on its opposite side, and a connecting piece is mounted on the mounting groove, with the connecting piece located within the enclosure of the mounting groove.

[0012] The bottom of the housing groove is provided with an abutment hole, and the connecting piece is provided with an abutment piece at the position corresponding to the abutment hole.

[0013] The connecting piece is U-shaped or J-shaped, and the abutting piece is located on the side of the connecting piece away from the mounting block.

[0014] The connecting piece and the mounting block are respectively provided with corresponding mounting holes, and the insertion block is provided with blind holes corresponding to the mounting holes. Locking fasteners are installed between each of the corresponding mounting holes and blind holes.

[0015] The snap-fit ​​protrusion includes a support portion and an integrally connected matching portion. The lower side of the connection position between the mounting block and the insertion block is supported by the support portion, and the matching portion matches the bottom of the snap-fit ​​groove.

[0016] After adopting the above structure, the present invention has the following beneficial effects: 1. The present invention adopts a matching mounting and dismounting component. When the walkie-talkie is mounted on the back clip, the insert block is inserted into the back clip groove, so that the snap-fit ​​groove on the mounting block engages with the snap-fit ​​protrusion on the back clip. At the same time, the two snap-fit ​​protrusions engage with their corresponding snap-fit ​​seams, thereby realizing the fixed mounting of the walkie-talkie on the back clip. The mounting structure between the walkie-talkie and the back clip is stable, and the installation is simple and convenient. When the walkie-talkie is removed from the back clip, the walkie-talkie is rotated 180°. Since each snap-fit ​​protrusion is tightly connected to the corresponding snap-fit ​​seam along the snap-fit ​​seam and the snap-fit ​​protrusion engages with the snap-fit ​​groove, the rotation of the walkie-talkie can easily disengage the snap-fit ​​protrusion from the snap-fit ​​seam and the snap-fit ​​protrusion from the snap-fit ​​groove, which facilitates the rotation of the walkie-talkie and allows it to be removed from the back clip. The disassembly structure is simple and convenient, saving time and effort.

[0017] 2. This utility model adopts an installation mating block that snaps onto the housing. Combined with the setting of the connecting piece, one side of the connecting piece snaps onto the housing, and the other side is installed together with the installation mating block and the insertion block through the locking fastener. This allows the mating assembly to be detachably installed on the housing. If the parts in the mating assembly are worn, it is convenient to disassemble, repair or replace them. Moreover, the U-shaped or J-shaped setting of the connecting piece provides a buffer space between the back clip and the housing, which improves the service life of the mating assembly.

[0033] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0034] A back clip structure for walkie-talkies, applicable to various walkie-talkies sold on the market, such as... Figure 1 As shown, the back clip structure is installed on the back of the walkie-talkie housing 100, and the back clip structure includes a back clip 1 and a mounting and dismounting assembly 2. The back clip 1 is an improvement on the back clip conventionally used in walkie-talkies, that is, the back clip 1 includes a first clip 11 and a second clip 12. The first ends of the first clip 11 and the second clip 12 are hinged to each other in a conventional manner, which will not be described in detail here. In this embodiment, the mounting and dismounting assembly and the first clip 11 are mounted and dismounted in the following manner.

[0035] For ease of description, the reference state of this utility model is the state in which the walkie-talkie is installed on the back clip 1 and the back clip 1 is installed on the user's body. The side on which the back clip 1 and the mounting and dismounting components cooperate is the cooperating side, and the side on which they are opposite is the opposing side. When the back clip 1 is installed on the user's body, the direction of the back clip 1 corresponding to the head of the human body is the upper side, that is, the position of the hinge point of the back clip 1 is the upper side, and the direction of the back clip 1 corresponding to the feet of the human body is the lower side.

[0036] like Figure 1-6As shown, the aforementioned mounting and dismounting assembly 2 includes a mounting mating block 3 and an insertion block 4. The mounting mating block 3 is fixedly or detachably mounted on the back of the housing 100 on its opposite side. The insertion block 4 is installed at the middle position of the mating side of the mounting mating block 3. The mating side of the first clamping piece 11 of the aforementioned back clamp 1 has a back clamping groove 111. The upper side of the first clamping piece 11 has a back clamping opening for the insertion block 4 to enter. The back clamping opening and the back clamping groove 111 are interconnected. The opening of the back clamping groove 111 faces the mating side of the mounting mating block 3, and the opening of the back clamping groove 111 extends to the back clamping opening. Thus, the insertion block 4 enters from the back clamping opening and is confined within the back clamping groove 111. Furthermore, a snap-fit ​​protrusion 112 is provided at the middle position of the lower side of the first clamping piece 11. That is, the lower side of the mating side of the first clamping piece 11 forms a retaining part 113. The opposite side of the retaining part 113 is part of the back clamping groove 111, and the snap-fit ​​protrusion 112 is integral. The upper side of the enclosure 113 is connected to the mounting block 3, and a snap-fit ​​groove 31 is provided on the mounting side corresponding to the snap-fit ​​protrusion 112. The snap-fit ​​protrusion 112 and the snap-fit ​​groove 31 are snap-fitted together. Furthermore, the enclosure 113 is provided with snap-fit ​​seams 114 on both sides corresponding to the snap-fit ​​protrusion 112. The two snap-fit ​​seams 113 are respectively connected to the back clamp groove 11, and the two snap-fit ​​seams 114 extend along the length (up and down) of the back clamp 1. Preferably, the first end of the two snap-fit ​​seams 114 passes through the upper side of the enclosure 113, and the second end of the two snap-fit ​​seams 114 extends downward to the bottom and continues to extend to the opposite side of the first clamp 11, so that there is space for elastic deformation, which facilitates snap-fitting or disengaging. The mounting block 3 is integrally connected with a snap-fit ​​protrusion 32 at the position corresponding to the two snap-fit ​​seams 114, that is, the two snap-fit ​​seams 114 are snap-fitted with the corresponding snap-fit ​​protrusion 32. In this embodiment, during the process of rotating the housing 100 relative to the back clip 1 to remove the housing 100, the snap-fit ​​protrusion 112 and the snap-fit ​​groove 31 disengage from each other, and the two snap-fit ​​protrusions 11 disengage from their corresponding snap-fit ​​seams 114 respectively.

[0037] like Figure 2-3 As shown, the aforementioned assembly 2 is detachably mounted on the back of the housing 100 to facilitate maintenance or replacement of the components or the entire assembly. The specific structure of the assembly is as follows.

[0038] The back of the aforementioned housing 100 is provided with a housing groove 101. The housing groove 101 has an upper port, and the upper end face is used for the mounting mating block 3 to enter. The opening of the housing groove 101 faces the mating side of the back clip 1 so as not to affect the assembly of the mounting mating block 3. The two sides of the housing groove 101 are respectively formed with slot portions 102. Both slot portions 102 are n-shaped. The opposite side of the mounting mating block 3 is integrally connected with mating slot portions 33 corresponding to the positions of the two slot portions 102. The two mating slot portions 33 are respectively engaged with the corresponding slot portions 102. In this way, by inserting the two mating slot portions 33 into the corresponding slot portions 102, the mounting mating block 3 can be installed on the back of the housing 100.

[0039] Furthermore, the mounting block 3 described above has a mounting groove 34 on its opposite side. A connecting piece 5 is mounted on the mounting groove 34. The connecting piece 5 can be a plastic sheet or a metal sheet, etc., with elasticity. The connecting piece 5 is located within the enclosure of the mounting groove 34. The bottom of the housing groove 101 has an abutment hole 1011. Abutment piece 51 is integrally connected to the connecting piece 5 at the position corresponding to the abutment hole 1011. The abutment piece 51 is made of an elastic material, such as a metal sheet or plastic sheet made of stainless steel. One side of the abutment piece 51 is integrally connected to the connecting piece 5, and the other side is arranged upwardly in the direction away from the mounting block 3, so as to install the connecting piece 5 on the back of the housing 100 with a buffer. Preferably, the connecting piece 5 can be U-shaped or J-shaped, that is, the abutment piece 51 is located on the opposite side of the connecting piece 5. The mating side of the connecting piece 5 is installed together with the mounting block 3 and the insertion block through the following installation structure.

[0040] The above-mentioned installation structure is as follows: the mating side and the unmoored side of the connecting piece 5 are respectively provided with corresponding mounting holes 52. The mounting mating block 3 is also provided with mounting holes corresponding to the mounting holes 52 on the connecting piece 5. The insertion block 4 is provided with blind holes 41 corresponding to the three corresponding mounting holes. The corresponding mounting holes and blind holes 41 are jointly provided with locking fasteners 6. In this embodiment, the locking fasteners 6 can be self-tapping screws, screws, pins or bolts, etc. When the locking fasteners 6 are bolts or screws, the blind holes of the insertion block 4 can be threaded holes. In this way, the locking fasteners 6 pass through the two mounting holes 52 on the connecting piece 5 and the mounting block on the mounting mating block 3 in sequence and are screwed into the blind holes 42 of the insertion block 4, thereby realizing the installation of the connecting piece 5, the mounting mating block 3 and the insertion block 4 together. Then, the unmoored side of the connecting piece 5 is installed on the back of the housing 100 in the aforementioned manner, so that the mating assembly 2 can be installed on the back of the housing 100.

[0041] Preferably, to ensure the stability of the installation structure, the opposite side of the insertion block 4 is provided with two mounting slots 41, which are arranged opposite to each other. On the mating side of the mounting mating block 3, a mounting protrusion 35 is integrally connected to the position corresponding to the two mounting slots 41. Preferably, the two mounting protrusions 35 are arranged sequentially from top to bottom and are arranged opposite to each other. In this way, the insertion block 4 and the mounting mating block 3 are installed together by the two mounting protrusions 35 respectively engaging in the corresponding mounting slots 41.

[0042] It should be noted that the aforementioned mounting and disassembly assembly 2 can also be directly fixed to the back of the housing 100. This fixing structure can adopt existing conventional fixing structures, such as directly bonding, hot-pressing or screwing the mounting mating block 3 to the back of the housing 100.

[0043] like Figure 2-5 As shown, in the aforementioned mounting and dismounting assembly 2, the insertion block 4 is T-shaped, meaning the insertion block 4 includes an integrally connected large head and a cylindrical body. The large head of the insertion block 4 has a disc-like structure, and the cylindrical body of the insertion block 4 is cylindrical. The large head of the insertion block 4 is adapted to the lower part of the back clamp groove 111. In this embodiment, the large head of the insertion block 4 is inserted into the back clamp groove 111 of the back clamp 1, so that the insertion block 4 is engaged in the back clamp groove 111. The two mounting slots 42 are respectively located on the side of the cylindrical body. Preferably, as shown... Figure 6 As shown, limiting grooves 1111 are respectively provided on the two opposite side walls of the back clip groove 111. The two limiting grooves 111 extend in the vertical direction, and the thickness of the two limiting grooves 111 gradually decreases from bottom to top. The two limiting grooves 111 respectively cooperate with the large head of the insertion block 4 for limiting. In this way, the insertion block 4 is inserted into the back clip groove 111, which plays a role in limiting and guiding, so that the insertion block 4 is locked in the back clip groove 111. During the clockwise or counterclockwise rotation of the walkie-talkie housing 100, the insertion block 4 is limited to prevent it from shifting, and at the same time, it is convenient for the operator to push the corresponding locking part out.

[0044] Furthermore, in the first clip 11 of the back clip 1, the snap-fit ​​protrusion 112 includes a support portion and an integrally connected matching portion. After the mounting and dismounting assembly 2 is assembled, the lower side of the connection position between the insertion block 4 and the mounting mating block 3 is supported by the support portion, and the lower side of the connection position of the two is adapted to the support portion. The matching portion matches the bottom of the snap-fit ​​groove 31, so that when the mounting mating block 3 and the back clip 1 are snap-fitted together, the mounting mating block 3 together with the corresponding part of the insertion block 4 is supported by the support portion.

[0045] Furthermore, in use, the aforementioned mounting and dismounting assembly 2 is installed on the back of the walkie-talkie housing 100.

[0046] The present invention discloses a back clip structure for a walkie-talkie. The specific installation process is as follows: the insertion block 4 mounted on the housing 100 of the walkie-talkie is inserted into the back clip groove 111 on the back clip 1, and the snap-fit ​​groove 31 on the mounting mating block 3 snaps onto the snap-fit ​​protrusion 112 on the back clip 1. At the same time, the two snap-fit ​​protrusions 32 move downward along the corresponding snap-fit ​​seams 114 until the two snap-fit ​​protrusions 32 snap onto the lower part of the corresponding snap-fit ​​seams 114. At this time, the lower side of the mounting mating block 3 and the insertion block 4 that are connected to each other is supported by the supporting part of the snap-fit ​​protrusion 112. In this way, the housing 100 is installed on the back clip 1 by using the mounting and dismounting assembly 3.

[0047] The disassembly process of the walkie-talkie is as follows: The operator manually pushes the walkie-talkie housing 100 to rotate clockwise or counterclockwise. The rotation of the housing 100 drives the mounting and disassembly assembly 2 to move together. At this time, the large head of the insertion block 4 rotates in the back clamp groove 111. Due to the action of the two limiting grooves 1111, it rotates on its own. At the same time, the circumferential force of the mounting and disassembly block 3 makes it easy for the two locking protrusions 32 on it to disengage from the corresponding locking seams 114 on the back clamp 1. The locking groove 31 on the mounting and disassembly block 3 disengages from the locking protrusions 112. At this time, the insertion block 4 is always located in the back clamp groove 111. After the housing 100 rotates 180°, the locking groove 31 and the two locking protrusions 32 are located at the opening of the back clamp groove 111. Then, the housing 100 is pushed upward so that the insertion block 4 moves upward along the opening of the back clamp 111, thereby removing the housing 100 together with the mounting and disassembly assembly 2 from the back clamp 1.

[0048] The above description is only a preferred embodiment of this invention. All equivalent changes and modifications made within the scope of the claims of this utility model shall fall within the scope of the claims of this utility model.
