Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, and in particular to a circuit board that is easy to install. Background Technology

[0002] Currently, most circuit boards on the market are connected to the mounting base by bolting. The disadvantages of this method are that the screws required for circuit board installation are usually small in size, so it is difficult to align the screws with the mounting holes on the circuit board and the mounting base, and they are easy to drop from the hand. In addition, circuit boards generally require four screws for installation, which is relatively time-consuming. Utility Model Content

[0003] This invention proposes a circuit board that is easy to install, solving the aforementioned problems existing in the use of the prior art.

[0004] The technical solution of this utility model is implemented as follows: a circuit board that is easy to install includes a circuit board body and a mounting base. Limiting grooves are formed on both the left and right end faces of the circuit board body. Limiting posts are provided on the mounting base corresponding to the limiting grooves. The limiting posts abut against the groove surfaces of the limiting grooves. The lower end of the limiting post is rotatably connected to the mounting base. A height limiting mechanism is provided at the upper end of the limiting post. The height limiting mechanism includes an upper limiting plate and a lower limiting plate disposed on the limiting post. The lower limiting plate is fixedly disposed on the limiting post. The upper limiting plate is slidably disposed above the lower limiting plate. A clamping mechanism is provided on the limiting post to allow the upper limiting plate to slide downwards. The circuit board body is abutted between the upper and lower limiting plates.

[0005] The present invention is further configured such that: the mounting base is provided with an elastic torsion mechanism for keeping the limiting stake in a vertical state.

[0006] The present invention is further configured such that: the clamping mechanism includes an elastic pushing member, which is abutted between the upper end of the limiting post and the upper end of the upper limiting plate.

[0007] The present invention is further configured such that: the elastic torsion mechanism includes a torsion spring, one end of the torsion spring is fixed to the mounting base, the other end of the torsion spring is fixed to the limiting post, and a retaining wall is provided on the side of the limiting post near the middle of the circuit board, the retaining wall being used to ensure that the maximum pushing angle of the torsion spring on the limiting post does not exceed degrees.

[0008] The present invention is further configured such that two limiting grooves are provided on the left and right end faces of the circuit board body, one in front and one behind.

[0009] The present invention is further configured such that: two connecting plates are provided on the mounting base, and the connecting plates are respectively fixedly connected to the upper limit plates located at the left and right ends of the circuit board body. The connecting plates are used to drive the upper limit plates at the left or right end of the circuit board body to slide synchronously on the limit stakes.

[0010] The present invention is further configured such that the elastic pushing member is a spring.

[0011] In summary, the beneficial effects of this utility model are as follows:

[0012] 1. With this setting, when installing the circuit board, you only need to insert the limit pin into the limit groove, and then hold the circuit board body between the upper limit plate and the lower limit plate. Compared with screws, which need to be aligned with two mounting holes at the same time, the positioning of the limit pin is easier to achieve. In addition, the distance between the upper limit plate and the lower limit plate can be adjusted, so it is also convenient to place the circuit board body between the upper limit plate and the lower limit plate without the need for other tools.

[0013] 2. The elastic torsion mechanism can prevent the limit post from excessively squeezing both sides of the circuit board.

[0014] 3. People can lift the connecting plate upwards so that the two limit posts at the same end of the circuit board can simultaneously engage and lock the circuit board, making the disassembly and installation of the circuit board more convenient and faster. Attached Figure Description

[0020] The following will refer to the appendix in the embodiments of this utility model. Figure 1-3 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Example:

[0022] like Figures 1 to 3 As shown, this utility model discloses a circuit board that is easy to install, including a circuit board body 1 and a mounting base 2. The circuit board body 1 has two limiting grooves 11 spaced apart on its left and right end faces. At the same time, a limiting post 3 is provided on the mounting base 2 corresponding to each limiting groove 11. In this structure, the limiting post 3 is used to abut against the groove surface of the limiting groove 11, thereby locking the circuit board body 1 between the limiting posts 3.

[0023] The upper end of the limiting post 3 is provided with a height limiting mechanism, which includes an upper limiting plate 31 and a lower limiting plate 32 provided on the limiting post 3. The lower limiting plate 32 is fixedly provided on the limiting post 3, and the upper limiting plate 31 is slidably provided above the lower limiting plate 32. The limiting post 3 is provided with a clamping mechanism for making the upper limiting plate 31 slide downward. In this structure, the circuit board body 1 is held between the upper limiting plate 31 and the lower limiting plate 32, thereby fixing the height position of the circuit board body 1.

[0024] The lower end of the limiting post 3 is rotatably connected to the mounting base 2. The mounting base 2 is provided with an elastic torsion mechanism for keeping the limiting post 3 in a vertical state. The elastic torsion mechanism includes a torsion spring 34. One end of the torsion spring 34 is fixed to the mounting base 2, and the other end is fixed to the limiting post 3. At the same time, a supporting wall 35 is provided on the side of the limiting post 3 near the middle of the circuit board. The supporting wall 35 is used to abut against the side wall of the limiting post 3, so that the maximum pushing angle of the torsion spring 34 on the limiting post 3 does not exceed 90 degrees.

[0025] The clamping mechanism includes an elastic pusher 33, which is abutted between the upper end of the limiting post 3 and the upper end of the upper limit plate 31. The elastic pusher 33 may be a spring.

[0026] The mounting base 2 is provided with two connecting plates 36, which are fixedly connected to the upper limit plates 31 located at the left and right ends of the circuit board body 1, respectively. In this structure, the connecting plates 36 are used to drive the two upper limit plates 31 at the left end or the two upper limit plates 31 at the right end of the circuit board body 1 to slide synchronously on the limit stakes 3.

[0027] The working principle of the above structure is as follows: When the circuit board body 1 needs to be installed, people can lift the connecting plate 36 upward and push the connecting plate 36 to drive the limiting stake 3 to rotate together, so that the limiting stake 3 swings away from the other connecting plate 36. At this time, one end of the circuit board body 1 can be inserted between the upper limiting plate 31 and the lower limiting plate 32 on the same side as the connecting plate 36. Then, the same operation is performed on the other connecting plate 36. The other end of the circuit board body 1 can be fixed in the same way. Finally, the circuit board body 1 can be fixed between the limiting stakes 3 and horizontally set on the mounting base 2.

[0028] It should also be noted that the terms used in this utility model, such as "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

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.
