[0024] The utility model provides a quick and easy disassembly peripheral keyboard bracket expansion device, which solves the problems of inconvenient disassembly or instability in the prior art solutions, and achieves the beneficial effects of flexible and easy disassembly function, low manufacturing cost, good market economy, etc.
[0025] See also Figures 1 to 3 , a quick and easy disassembly peripheral keyboard bracket expansion device of an embodiment of the utility model includes a horizontally arranged keyboard plate 6, and the left keyboard ceiling piece 4 and the right keyboard ceiling piece 5 are respectively connected to the two sides of the keyboard plate 6. The bottom surface of the table is connected with a left panel fixing piece 1 and a right panel fixing piece 2, the left keyboard ceiling piece 4 is detachably connected to the left panel fixing piece 1, and the right keyboard ceiling piece 5 is detachably connected to the right panel fixing piece 2, so as to realize the connection between the keyboard plate 6 and the table plate of the office desk.
[0026] Furthermore, both the left keyboard ceiling piece 4 and the right keyboard ceiling piece 5 are provided with a limit stopper 7, and both the left panel fixing piece 1 and the right panel fixing piece 2 are provided with a threaded hole 8, in which a tension limit threaded knob 3 is threadedly connected. After the tension limit threaded knob 3 is tightened, the tension limit threaded knob 3 and the limit stopper 7 are pressed against each other; at the same time, under the action of the tension limit threaded knob 3, the left keyboard ceiling piece 4 and the left panel fixing piece 1 are pressed against each other, and the right keyboard ceiling piece 5 and the right panel fixing piece 2 are pressed against each other; thus, after the assembly, the detachable fixation is achieved through physical friction.
[0027] In a preferred embodiment, both the left panel fixing member 1 and the right panel fixing member 2 are provided with inverted hook teeth 10, and both the left keyboard ceiling member 4 and the right keyboard ceiling member 5 are provided with inverted hook slots 9. The inverted hook teeth 10 are, for example, plate-shaped, and the inverted hook slots 9 are bar-shaped holes, and the inverted hook teeth 10 are plugged in with the inverted hook slots 9. When the tension limit threaded knob 3 and the limit stopper 7 are in contact with each other, the inverted hook teeth 10 and the inverted hook slots 9 are in contact with each other on the side close to the tension limit threaded knob 3. In other words, the inverted hook teeth 10 are in contact with the inner wall of one end of the bar-shaped hole of the inverted hook slot 9.
[0028] More specifically, see also Figure 6 The inverted hook teeth 10 are extended from top to bottom, and the lower part of the inverted hook teeth 10 has a hook portion 11 with the tip facing the tension limit thread knob 3. The length of the inverted hook slot hole 9 is sufficient to allow the inverted hook teeth 10 to penetrate, and the upper part of the inverted hook teeth 10 can move in the inverted hook slot hole 9 along the length direction of the inverted hook slot hole 9 (such as the front-to-back direction relative to the user). Then, as the tension limit thread knob 3 is screwed in, the left / right side keyboard ceiling piece and the inverted hook slot hole 9 thereon are pushed and move relative to the inverted hook teeth 10 (for example, move backward), and finally resist and tighten. Due to the existence of the hook portion 11, even if the tension limit thread knob 3 is accidentally loosened, the keyboard ceiling piece and the keyboard panel 6 are not easy to fall off.
[0029] See also Figure 4The left panel fixing member 1 and the right panel fixing member 2 both include a fixing member connecting plate 12, which is, for example, a horizontal strip-shaped plate. One end (for example, the front end) of the fixing member connecting plate 12 is provided with a threaded hole plate 13 extending downward, and the threaded hole plate 13 is provided with a threaded hole 8. One side of the fixing member connecting plate 12 is provided with a hook tooth 10. The left keyboard ceiling member 4 and the right keyboard ceiling member 5 both include a ceiling member body 14, which is, for example, an upright plate-shaped member, used to form a required space between the keyboard panel 6 and the bottom surface of the table panel. The lower part of the ceiling member body 14 is connected to the keyboard panel 6; for example, it has a bent plate, which is further connected to the keyboard panel 6 with bolts. A ceiling mounting plate 15 is provided on the upper part of the ceiling body 14. The ceiling mounting plate 15 is, for example, a horizontal strip plate. A stopper 7 is provided at one end of the ceiling mounting plate 15. The stopper 7 and the threaded hole plate 13 are located on the same side (for example, both are located at the front end). The ceiling mounting plate 15 is provided with a hook slot 9 on the side close to the ceiling body 14. Of course, the hook slot 9 and the hook teeth 10 are located on the same side. With such a configuration, after installation, the hook teeth 10 will fit with the ceiling body 14, and the structure at the end of the hook teeth 10, such as the hook portion 11, is not easy to scratch the human body.
[0030] More preferably, if Figure 4 , Figure 5 As shown, in the right keyboard ceiling piece 5, the hook slot 9 is located on the left side of the ceiling piece body 14; symmetrically, in the left keyboard ceiling piece 4, the hook slot 9 is located on the right side of the ceiling piece body 14. In this arrangement, the ceiling piece body 14 is located on the outside, and the hook teeth 10 are attached to the inside, which is less likely to be touched.
[0031] The left panel fixing part 1, the right panel fixing part 2, the left keyboard ceiling part 4, and the right keyboard ceiling part 5 are, for example, iron parts (stainless steel parts). The fixing part connecting plate 12 is connected to the bottom surface of the table board, for example, by fastening screws, and the fixing part connecting plate 12 is provided with required through holes, for example, two through holes, for installing fastening screws; accordingly, the ceiling part mounting plate 15 is provided with screw avoidance holes 16 corresponding to the fastening screws on the fixing part connecting plate 12, so that the fixing part connecting plate 12 and the ceiling part mounting plate 15 can fit smoothly.
[0032] like Figure 5 , Figure 6 In the illustrated embodiment, in a left panel fixing member 1 or a right panel fixing member 2, the number of the inverted hook teeth 10 is more than two and they are distributed along the length direction of the inverted hook slot hole 9. For example, there are two inverted hook teeth 10 and two hook slot holes 9, which is convenient for installation and alignment and provides more positioning functions. The specific setting position, size, etc. can be adjusted as needed.
[0033] Preferably, both the left panel fixing member 1 and the right panel fixing member 2 are provided with an end hook tooth 17, and the end hook tooth 17 adopts a structure similar to the hook tooth 10, and the end hook tooth 17 is located at the end away from the tension limit thread knob 3, and the end hook tooth 17 is located outside the end of the left keyboard ceiling member 4 and the right keyboard ceiling member 5 away from the tension limit thread knob 3; after tightening and installing, the ceiling member mounting plate 15 and the end hook tooth 17 are abutted against each other. It can be understood that the utility model is not limited to this, and the abutment and tightening can be achieved at other locations through other structures.
[0034] See also Figure 2 , Figure 3 Preferably, the keyboard plate 6 is located on the side of the table plate facing the user (or the front side), the tension limit thread knob 3 is located on the side facing the user, and the keyboard plate 6 extends out of the table plate; this arrangement can better match the usage habits of ordinary people and is convenient for finding and turning the tension limit thread knob 3. It can be understood that this solution can be applied to various types of tables.
[0035] In summary, the main functional features of the utility model are as follows:
[0036] This solution uses the principle of inverted hook teeth and the principle of physical friction fixing and limiting to implement functions. The design is simple and ingenious, has market economic value, and is easy to disassemble and flexible. The left panel fixing part 1 and the right panel fixing part 2 are fixed to the original work desktop through fastening screws to form a component, and the left keyboard ceiling part 4 and the right keyboard ceiling part 5 and the keyboard board 6 are fixed to form a component through fastening screws. The above two components are matched and hung correspondingly through the inverted hook slot hole 9 and the inverted hook teeth 10, and then the threaded rod of the tension limiting thread knob 3 passes through the threaded hole 8 of the left panel fixing part 1 / the right panel fixing part 2, and supports the limiting baffle 7 of the left keyboard ceiling part 4 / the right keyboard ceiling part 5, and tightens the tension limiting thread knob 3, so that the left panel fixing part 1 / the right panel fixing part 2 are respectively fixed and limited with the left keyboard ceiling part 4 / the right keyboard ceiling part 5 by the principle of physical friction; in this way, the expansion and fixation of the peripheral keyboard bracket is realized. When disassembling, it is only necessary to loosen and remove the tension limit threaded knob 3, and move the inverted hook slots 9 of the left keyboard ceiling piece 4 and the right keyboard ceiling piece 5 to easily remove it.
