Description

Technical Field

[0001] The utility model relates to the technical field of quick-release structures, in particular to a self-locking quick-release structure. Background Art

[0002] Satellite wireless receiving terminals, as ground-based terminals for receiving satellite data signals, can be installed in home gardens, rooftops, and car rooftops. Due to the differences in application scenarios, the installation methods and requirements for satellite wireless receiving terminals on different ground supports vary significantly. For example, when installing on a structure with beams, such as a car roof or rooftop, a bracket that extends to accommodate the beams is required.

[0003] like Figure 1 In the prior art shown, a satellite wireless receiving terminal 1 has a concave slot 2, into which a sliding block is slidably connected. The concave slot 2 has only one opening in the sliding direction of the sliding block, that is, the sliding block can only slide into the concave slot 2 or out of the concave slot 2 along the opening of the concave slot 2.

[0004] How to design a quick-disassembly structure suitable for installation on beams such as car roofs and roofs based on the structural characteristics of the above-mentioned satellite wireless receiving terminal is an urgent problem to be solved. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a self-locking quick-release structure that can be adapted for installation on beams such as a vehicle roof or a roof.

[0006] The above technical purpose of the present utility model is achieved through the following technical solutions: a self-locking quick-release structure, comprising a satellite wireless receiving terminal with a slide groove, wherein the satellite wireless receiving terminal is provided with at least one limiting groove on the inner wall of the slide groove, a sliding block is slidably connected in the slide groove, and a card block is provided on the sliding block that cooperates with the limiting groove, and the sliding block is made of a material that will deform under the action of external force.

[0007] The satellite wireless receiving terminal also includes a movable opening connected to the slide groove. The satellite wireless receiving terminal is provided with an outer edge on the outer periphery of the movable opening for limiting the movement of the sliding block in a direction away from the satellite wireless receiving terminal. The outer edge is engaged with the outer periphery of the sliding block.

[0008] Further, a crossbeam fixing device is provided on the side of the sliding block away from the satellite wireless receiving terminal; the crossbeam fixing device includes a vertical rod, a horizontal rod, and a movable rod that are sequentially connected end to end, and an accommodating cavity for placing the crossbeam is enclosed among the vertical rod, the horizontal rod, the movable rod, and the sliding block;

[0009] One end of the movable rod away from the horizontal rod is detachably connected to the sliding block to open or close the accommodating cavity.

[0010] In summary, the present utility model has the following beneficial effects:

[0011] 1. In actual use, the accommodating cavity is often opened to allow an external crossbeam to be placed into the accommodating cavity to complete the embedding (see Figure 4 ). After the crossbeam is embedded, the accommodating cavity is closed to complete the operation of installing the crossbeam fixing device on the crossbeam (see Figure 5 ).

[0012] It can be seen from this that the self-locking quick-release structure of the present application can realize the detachable setting of the satellite wireless receiving terminal in application scenarios with a crossbeam structure such as the roof of a vehicle or a building.

[0019] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0020] As Figure 2-5As shown in the figure, a self-locking quick-release structure includes a satellite wireless receiving terminal 1 with a "concave-shaped" chute 2. At least one limiting groove 3 is provided on the inner wall of the chute 2 of the satellite wireless receiving terminal 1. A sliding block 4 is slidably connected in the chute 2, and a clamping block 5 is provided on the sliding block 4 and is matched with the limiting groove 3. The sliding block 4 is made of a material that will deform under an external force.

[0021] In the above structure, the limiting groove 3 is constructed inside the chute 2, and a clamping block 5 that can be matched with the limiting groove 3 is protruded on the sliding block 4. So that when the clamping block 5 is clamped and matched with the limiting groove 3, the sliding block 4 can be self-locked in the chute 2. At the same time, the sliding block 4 covers the limiting groove 3 to prevent the limiting groove 3 from being exposed.

[0022] Further, a crossbeam fixing device 6 is provided on the side of the sliding block 4 away from the satellite wireless receiving terminal 1. The crossbeam fixing device 6 includes a vertical rod 7, a horizontal rod 8, and a movable rod 9 that are connected end to end in sequence. An accommodating cavity for placing the crossbeam is enclosed among the vertical rod 7, the horizontal rod 8, the movable rod 9, and the sliding block 4.

[0023] Among them, one end of the movable rod 9 away from the horizontal rod 8 is detachably connected to the sliding block 4 to open or close the accommodating cavity.

[0024] In actual use, the accommodating cavity is often opened to allow an external crossbeam to be placed into the accommodating cavity to complete the embedding (see Figure 4 ). After the crossbeam is embedded, the accommodating cavity is closed to complete the operation of installing the crossbeam fixing device 6 on the crossbeam (see Figure 5 ).

[0025] Further, one end of the movable rod 9 is rotatably connected to the horizontal rod 8, and a knob 10 is threadedly connected to the other end of the movable rod 9. The rotation of the knob 10 can adjust the displacement amount (relative position) of the knob 10 on the movable rod 9, and thus the relative position between the knob 10 and the movable rod 9 can be adjusted.

[0026] One end of the sliding block 4 is provided with a fixing step 11 that is matched with the knob 10.

[0027] In specific applications, the knob 10 is rotated in the reverse direction to increase the distance between the knob 10 and the movable rod 9. Then the knob 10 gradually disengages from the fixing step 11. At this time, the knob 10 and the movable rod 9 connected to the knob 10 can rotate in the direction of the arrow as shown in Figure 4 to open the accommodating cavity.

[0028] When closing the accommodation cavity, the knob 10 moves above the fixed step 11. Then the knob 10 rotates forward so that the distance between the knob 10 and the movable rod 9 decreases, and then the knob 10 gradually abuts against the fixed step 11. At this time, the rotation adjustment of the knob 10 can set the knob 10 on the fixed step 11; when the knob 10 is fastened to the step 11, an interference fit force will also be generated between the knob 10 and the fixed step 11.

[0029] In the above, the forward rotation and reverse rotation of the knob 10 are only for illustrative purposes and do not constitute a further limitation on the knob 10.

[0030] Furthermore, since the quick-release structure of the present application is applied to outdoor car roofs, roofs, etc. with beam structures, the knob 10 can be designed with an anti-theft structure. For example, the knob 10 is a knob 10 with a keyhole structure to improve the safety of outdoor use.

[0031] Furthermore, the end of the vertical rod 7 far from the cross rod 8 is detachably connected to the sliding block 4.

[0032] Furthermore, at the corresponding position of the sliding block 4 with respect to the clamping block 5, a force application part 12 for holding by the human hand is provided. (See Figure 3 and Figure 4 shown)

[0033] In this embodiment, the sliding block 4 includes a movable plate 13, and the clamping block 5 and the force application part 12 are respectively located on both sides of the movable plate 13. When the human hand holds the force application part 12, it will drive the movable plate 13 to deform so that the clamping block 5 disengages from the limiting groove 3. In this case, it can be regarded that the force application part 12 is provided at the corresponding position of the clamping block 5.

[0034] Furthermore, the number of the limiting grooves 3 matches the number of the clamping blocks 5.

[0035] Furthermore, the sliding block 4 is made of plastic. Plastic is inexpensive and will deform under external force.

[0036] In this embodiment, the limiting groove 3, the clamping block 5, and the force application part 12 are all in a corresponding relationship and there is a strong association. That is, the force application part 12 drives the clamping block 5 to disengage from the limiting groove 3. By setting the force application part 12 near the opening of the sliding groove 2, it is convenient for the human hand to hold and apply force, thereby completing the unlocking action of the sliding block 4.

[0037] Furthermore, the satellite wireless receiving terminal 1 further includes a movable port communicating with the sliding groove 2. The satellite wireless receiving terminal 1 is provided with an extension edge 14 for restricting the sliding block 4 from moving away from the satellite wireless receiving terminal 1 on the outer periphery of the movable port, and the extension edge 14 is U-shaped. The extension edge 14 is engaged with the outer periphery of the sliding block 4.

[0038] In this application, once the sliding block 4 and the satellite wireless receiving terminal 1 are in a locked state during the assembly process. That is, there is an opening on one side of the "concave" chute 2 for the sliding block 4 to slide, which means that the sliding block 4 must be detached along this opening to separate from the satellite wireless receiving terminal 1. During the process of sliding the sliding block 4 into the chute 2, the outer extension edge 14 always applies a force to the sliding block 4 in the direction towards the limit groove 3. Once the sliding block 4 and the latch 5 located on the sliding block 4 move to the position of the limit groove 3, the latch 5 will be quickly snapped into the limit groove 3 under the action of the outer extension edge 14, thus completing the locking of the sliding block 4 and the satellite wireless receiving terminal 1.

[0039] The unlocking action of the sliding block 4 is to lift first and then pull. That is, the unlocking action of the quick-release structure in this application is to lift first and then pull;

[0040] The "lift first" means: the human hand is placed on the force-applying part 12 of the sliding block 4 and applies a force in the direction away from the limit groove 3, causing the latch 5 to disengage from the limit groove 3;

[0041] The "pull later" means: the human hand is placed on the force-applying part 12 of the sliding block 4 and applies a force in the direction towards the opening of the "concave" chute 2 to drive the sliding block 4 to slide out of the chute 2 along the opening of the chute 2, so as to realize the separation of the sliding block 4 and the satellite wireless receiving terminal 1.

[0042] The specific embodiments are only explanations of the present invention, and they do not limit the present invention. Those skilled in the art can make modifications without creative contributions to this embodiment according to needs after reading this specification, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
