Description

Technical Field

[0001] This utility model relates to the field of signal generator technology, specifically to a function signal source device that is easy to install. Background Technology

[0002] A function signal generator is a signal generating device that can produce certain specific periodic time function waveform signals with a frequency range from a few microhertz to tens of megahertz. In addition to being used for testing in communication, instrumentation, and automatic control systems, it is also widely used in other non-electrical measurement fields.

[0003] In most cases, existing function signal generators are placed directly on a table for use. Some use U-shaped frames or similar support components to hold the function signal generator at a certain angle to the table. However, because the angle is fixed, it cannot be adjusted when the angle does not meet the usage habits of different users. Furthermore, adjusting the support component requires one hand to hold the function signal generator while the other hand controls the support component, making the adjustment process neither simple nor quick. In addition, the housing and cover of existing function signal generators are connected by bolts. When the signal generator needs to be repaired, tools must be used to remove each bolt one by one. This is inconvenient, affects the efficiency of maintenance, and the bolts are easily lost after removal, making subsequent installation inconvenient. Utility Model Content

[0010] Furthermore, multiple groups of positioning columns and positioning grooves are provided, and the positioning columns are adapted to the positioning grooves.

[0011] By adopting the above technical solution, multiple groups of positioning columns are inserted into multiple groups of positioning grooves, so that the shell cover can be limited and fixed.

[0012] Furthermore, sliding grooves are provided on both sides of the top of the shell, and sliding strips are provided on both sides of the bottom of the shell cover, and both the sliding strips and the sliding grooves are in a "convex" shape.

[0013] By adopting the above technical solution, with the cooperation of the sliding strips and the sliding grooves, on the one hand, the sealing performance between the shell cover and the shell is increased, and on the other hand, the shell cover and the shell are more stable after installation.

[0014] Furthermore, heat dissipation nets are provided on both sides of the shell.

[0016] Furthermore, a power socket is provided on the back of the shell.

[0017] By adopting the above technical solution, it is convenient to connect the device to the power supply line using the power socket.

[0018] Furthermore, a guide rod is provided between the mounting plates, and the threaded seat is slidably配合 with the guide rod.

[0019] By adopting the above technical solution, under the action of the guide rod, the movement of the threaded seat is more stable.

[0020] Furthermore, a handle is fixed on one side of the top of the shell cover.

[0021] By adopting the above technical solution, the staff can easily remove the shell cover from the shell using the handle, or it is convenient for the staff to install the shell cover onto the shell.

[0022] In summary, the main beneficial effects of the present utility model are as follows:

[0023] 1. This utility model, through the setting of lead screw, threaded seat and support rod, allows the operator to simply rotate the lead screw when the angle needs to be adjusted. The rotation of the lead screw causes the threaded seat to move, thereby changing the angle of the support rod, thus enabling stepless adjustment of the angle of the signal source device. This satisfies the usage habits of different operators and is more convenient to operate compared to traditional adjustment methods.

[0024] 2. This utility model, through the arrangement of a worm gear, a bidirectional worm, a connecting rod, a movable rod, a push-pull column, a positioning column, and a positioning groove, allows for easy maintenance of the signal source. When maintenance is required, the operator rotates the bidirectional worm, which drives the worm gear to rotate. The rotating worm gear then pushes the connecting rod to move via the push-pull column, causing the movable rod to move and disengage the positioning column from the positioning groove. The operator then slides the cover, disengaging the slide bar from the groove for internal maintenance. After maintenance, the operator inserts the slide bar back into the groove to seal the cover. Reversing the rotation of the bidirectional worm causes the worm gear to rotate in the opposite direction, and the push-pull column pulls the connecting rod, causing it to move the movable rod. This allows the positioning column to insert into the positioning groove and secure the cover, achieving the desired installation. The operation is simple and convenient, requiring no tools to disassemble or reassemble bolts, greatly improving maintenance efficiency. Attached Figure Description

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0033] The embodiments of this utility model will be described below based on its overall structure.

[0034] Example 1: A function signal source device that is easy to install, such as Figures 1-6 As shown, the device includes a base 1, to the top of which a housing 3 is movably connected via a connecting plate 2. A power socket 23 is located on the back of the housing 3, allowing easy connection to a power cord. A cover 8 is located on the top of the housing 3, with positioning grooves 25 on both sides. A control panel 9 is located on the outer surface of the housing 3. A bidirectional worm gear 16 and a connecting shaft 26 are mounted on the back of the housing 3. A dial 24 is fixed to the center of the outer surface of the bidirectional worm gear 16, and the dial 24 has anti-slip textures on its outer surface. The dial 24 facilitates the rotation of the bidirectional worm gear 16 by the operator, and the anti-slip textures increase the friction of the dial 24. The connecting shaft 26... A worm gear 17 is fixed to the outer surface of the housing 3. Movable rods 10 are installed on both sides of the back of the housing 3 via mounting blocks 18. A connecting rod 19 is movably connected to one side of the movable rod 10. The back of the worm gear 17 is movably connected to the connecting rod 19 via a push-pull column 27. A positioning column 22 is fixed to one end of the movable rod 10. A mounting plate 4 is fixed to the top of the base 1. A lead screw 13 is installed on the inner side of the mounting plate 4. A knob 15 is fixed to one end of the lead screw 13. The operator can easily rotate the lead screw 15 by turning the knob. A threaded seat 6 is provided on the outer surface of the lead screw 13. A support rod 14 is movably connected to the top of the threaded seat 6. One end of the support rod 14 is movably connected to the bottom of the housing 3.

[0035] See Figure 1 and Figure 3 In the above embodiment, the bottom of the base 1 is provided with an anti-slip pad 12, which is made of rubber material. The anti-slip pad 12 reduces the friction between the base 1 and the workbench, making the signal source device more stable.

[0036] See Figure 4 and Figure 5 In the above embodiment, multiple sets of positioning posts 22 and positioning grooves 25 are provided, and the positioning posts 22 and positioning grooves 25 are adapted to each other. By inserting multiple sets of positioning posts 22 into multiple sets of positioning grooves 25, the cover 8 can be limited and fixed.

[0037] See Figures 1-4, in the above embodiments, heat dissipation nets 7 are provided on both sides of the housing 3, and the heat inside the device can be discharged through the heat dissipation nets 7, thereby reducing the temperature inside the device.

[0038] Refer to Figure 2 , in the above embodiments, guide rods 5 are provided between the mounting plates 4, and the threaded seats 6 are slidably engaged with the guide rods 5. Under the action of the guide rods 5, the movement of the threaded seats 6 is more stable.

[0039] Refer to Figure 1 , Figure 3 and Figure 4 , in the above embodiments, a handle 11 is fixed on one side of the top of the shell cover 8. The staff can use the handle 11 to easily disassemble the shell cover 8 from the housing 3 or to easily install the shell cover 8 onto the housing 3.

[0040] Embodiment 2: In order to make the installation of the shell cover and the housing more stable and to improve the tightness between the shell cover and the housing, Embodiment 2 is improved on the basis of Embodiment 1. Refer to Figure 3 and Figure 4 , chutes 21 are provided on both sides of the top of the housing 3, and sliding strips 20 are provided on both sides of the bottom of the shell cover 8. Both the sliding strips 20 and the chutes 21 are in a "convex" shape. With the cooperation of the sliding strips 20 and the chutes 21, on the one hand, the tightness between the shell cover 8 and the housing 3 is increased, and on the other hand, the shell cover 8 is more stable after being installed on the housing 3.

[0041] The implementation principle of the present utility model is as follows: First, the staff places the device on the workbench. When the angle needs to be adjusted, the staff only needs to rotate the screw rod 13. The rotation of the screw rod 13 causes the threaded seat 6 to move, thereby changing the angle of the support rod 14, so that the angle of the signal source device can be adjusted steplessly to meet the usage habits of different staff. When the signal source needs to be repaired, the staff rotates the bidirectional worm 16. The bidirectional worm 16 drives the worm wheel 17 to rotate. After the worm wheel 17 rotates, it pushes the connecting rod 19 to displace through the push-pull column 27, thereby causing the movable rod 10 to displace, and further causing the positioning column 22 to disengage from the positioning groove 25. Then the staff slides the shell cover 8 so that the sliding strip 20 disengages from the chute 21 to repair the interior. After the repair is completed, the staff inserts the sliding strip 20 into the chute 21 to seal the housing 3 with the shell cover 8. Then, the bidirectional worm 16 is rotated in the reverse direction, causing the worm wheel 17 to rotate in the reverse direction. The push-pull column 27 pulls the connecting rod 19 to displace, thereby causing the connecting rod 19 to drive the movable rod 10 to displace, and further causing the positioning column 22 to be inserted into the positioning groove 25 to fix the shell cover 8, achieving the installation purpose.
