Abstract
Description
Technical Field
[0001] This utility model relates to the field of calibration device technology, and in particular to a pulse power source calibration device. Background Technology
[0002] A pulse calibrator is a device used to calibrate and test pulse signals in electronic equipment. It is mainly used to ensure the accuracy and reliability of the output signal of the pulse signal generator in various parameters (such as pulse amplitude, pulse width, rise time and fall time), and can calibrate the pulse peak scale factor and phase frequency characteristics of the measuring equipment.
[0003] Currently, most pulse calibrators adopt a square structure, and the large size of these models results in significant weight. Due to practical needs, in long-term stable calibration and testing environments, some pulse calibrators need to be installed in space-constrained scenarios such as server racks. To reduce space occupation, pulse calibrators are usually not designed with support structures on both sides, resulting in a lack of effective force points during handling. Although some calibrators are equipped with handles at the front and rear to optimize the handling experience, this design not only affects the operation of the control panel but also occupies additional space. Especially in high-density server rack installation environments, it is easy to cause spatial interference with surrounding equipment. Therefore, a pulse power source calibration device is proposed. Utility Model Content
[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.
[0005] In view of the problems existing in the current pulse power source calibration device, this utility model is proposed.
[0006] Therefore, the purpose of this utility model is to provide a pulse power source calibration device, which is suitable for solving the problem that some pulse calibrators usually do not have a support structure designed on both sides, resulting in a lack of effective force points during transportation, and that some calibrators, although equipped with handles at the front and rear ends, are prone to spatial interference with surrounding equipment.
[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a pulse power source calibration device, comprising:
[0008] The calibration unit includes a pulse calibrator, which has U-shaped storage slots on both sides.
[0009] The support unit includes two U-shaped handles, each with a pivot fixedly connected to both ends. Each pivot is rotatably connected to a corresponding storage slot. A gap for deflection is left between the storage slot and the U-shaped handle. A cylindrical groove is provided on the lateral gripping section of the U-shaped handle. An anti-slip sleeve is fixedly fitted inside the cylindrical groove of the U-shaped handle. A pair of horizontal limiting members for supporting the U-shaped handle are fixedly connected in each storage slot.
[0010] In a preferred embodiment of the pulse power source calibration device of this utility model, rubber strips are fixedly connected to both sides of the pulse calibrator along the edge of the receiving groove to alleviate the sharpness of the edge of the receiving groove on the hand.
[0011] As a preferred embodiment of the pulse power source calibration device of this utility model, each of the storage slots has an inclined groove at the bottom, and the inclined groove and the storage slot adopt a smooth transition design. The inclined groove is used to assist the fingers in applying force to rotate the U-shaped handle out of the storage slot.
[0012] In a preferred embodiment of the pulse power source calibration device of this utility model, the anti-slip sleeve has a plurality of anti-slip protrusions evenly distributed on its surface to enhance the friction of gripping the U-shaped handle.
[0013] As a preferred embodiment of the pulse power source calibration device of this utility model, the horizontal limiting member includes two pairs of support blocks, with two adjacent support blocks respectively fixed to the two ends of the inner wall of the storage groove, for horizontal support of the U-shaped handle in the gripping state.
[0014] In a preferred embodiment of the pulse power source calibration device of this utility model, the bottom of each support block is a semi-circular arc surface that fits the U-shaped handle, and a rubber pad is fixedly connected inside the arc surface at the bottom of each support block.
[0015] As a preferred embodiment of the pulse power source calibration device of this utility model, each of the storage slots has a pair of sponge pads fixedly connected to its inner wall, and one side of each sponge pad is an arc surface that fits the U-shaped handle.
[0016] In a preferred embodiment of the pulse power source calibration device of this utility model, each of the storage slots has a pair of magnetic rings fixedly connected to its inner wall, and metal blocks that attract the magnetic rings are built into the corresponding positions of the two U-shaped handles. The magnetic rings do not contact the U-shaped handles.
[0017] The beneficial effects of this utility model are as follows: When moving the pulse calibrator, the U-shaped handle can be deflected outward from the storage slot to provide a stable fulcrum for the operator, making it easy to move with less effort. When not moving, the U-shaped handle can be deflected inward and stored in the storage slot, so that the pulse calibrator has no protruding structure exposed, thereby reducing the volume occupied by the pulse calibrator in limited spaces such as cabinets.

[0029] Example 1
[0030] Reference Figures 1-3 The first embodiment of this utility model provides a pulse power source calibration device, which can provide a stable force application fulcrum for the operator using a U-shaped handle, making it easy to carry with minimal effort. When not in use, the U-shaped handle can be deflected inward and stored in a U-shaped storage slot, thereby reducing the volume occupied by the pulse calibrator. It includes: a calibration unit 100 and a support unit 200.
[0031] The calibration unit 100 includes a pulse calibrator 101, and both sides of the pulse calibrator 101 are provided with U-shaped storage slots 102.
[0032] The support unit 200 includes two U-shaped handles 201. Each U-shaped handle 201 has a rotating shaft 202 fixedly connected to both ends, which passes through the U-shaped handle 201. Each rotating shaft 202 is rotatably connected to a corresponding storage slot 102. There is a gap between the storage slot 102 and the U-shaped handle 201 for deflection. A cylindrical groove is provided on the horizontal gripping section of the U-shaped handle 201. An anti-slip sleeve 203 is fixedly sleeved in the cylindrical groove of the U-shaped handle 201. A pair of horizontal limiting members 204 for supporting the U-shaped handle 201 are fixedly connected in each storage slot 102.
[0033] The pulse calibrator 101 has U-shaped storage slots 102 on both sides for accommodating U-shaped handles 201. The two U-shaped handles 201 of the support unit 200 are rotatably connected to the corresponding storage slots 102 via rotating shafts 202 at both ends. The gap between the storage slots 102 and the U-shaped handles 201 provides space for the U-shaped handles 201 to deflect. When moving the pulse calibrator 101, the U-shaped handles 201 can rotate out of the storage slots 102 around the rotating shafts 202, and their lateral gripping sections... The anti-slip sleeve 203 enhances grip stability, and the horizontal limiting component 204 forms a horizontal limiting support for the U-shaped handle 201, allowing the user to exert force using the U-shaped handle 201, so as to carry the pulse calibrator 101 with less effort. When there is no need to carry it, the U-shaped handle 201 can be deflected and stored in the storage slot 102, so that there are no protruding structures around the pulse calibrator 101, thereby reducing the volume occupied by the pulse calibrator 101 in confined spaces such as cabinets.
[0034] Example 2
[0035] Reference Figure 1 and Figure 2 This is the second embodiment of the present invention. Unlike the previous embodiment, rubber strips 103 are fixedly connected to both sides of the pulse calibrator 101 along the edge of the storage groove 102 to alleviate the sharpness of the edge of the storage groove 102 on the hand.
[0036] The rubber strips 103 fixed on both sides of the pulse calibrator 101 along the edge of the storage groove 102, through their own elastic material properties, wrap and buffer the sharp edge of the storage groove 102. When the hand touches the edge of the storage groove 102 for operation, the rubber strips 103 can disperse the contact pressure and avoid the edge directly rubbing against the hand, thereby relieving the discomfort caused by the sharpness and improving the safety and comfort of operation.
[0037] Each storage slot 102 has a slanted groove 104 at the bottom. The slanted groove 104 and the storage slot 102 are designed with a smooth transition to reduce the sharpness felt by the hand. The slanted groove 104 is used to assist the fingers in applying force to rotate the U-shaped grip 201 out of the storage slot 102.
[0038] The inclined groove 104 at the bottom of each storage slot 102 provides space for the fingers to apply force. When it is necessary to rotate the U-shaped handle 201, the fingers can be inserted into the inclined groove 104. The inclined angle of the inclined groove 104 forms a force-saving fulcrum, making it easier to apply outward pushing force to the U-shaped handle 201, assisting it to rotate smoothly out of the storage slot 102 around the pivot 202, and reducing the difficulty of operation.
[0039] Example 3
[0040] Reference Figures 1-3This is the third embodiment of the present invention. Unlike the previous embodiment, the anti-slip sleeve 203 has multiple anti-slip protrusions evenly distributed on its surface to enhance the friction of gripping the U-shaped handle 201.
[0041] When holding the U-shaped handle 201, it effectively prevents relative slippage between the hand and the U-shaped handle 201, ensuring stable force application by the operator and improving the safety of operation during the handling process.
[0042] In addition, the horizontal limiting member 204 includes two pairs of support blocks 204a, with two adjacent support blocks 204a fixed to the two ends of the inner wall of the storage groove 102, for horizontal support of the U-shaped handle 201 in the gripping state.
[0043] When the U-shaped handle 201 is rotated out of the storage slot 102 into the gripping state, the support block 204a provides horizontal support to the U-shaped handle 201, ensuring that the U-shaped handle 201 maintains a stable force posture during transportation. Furthermore, the support block 204a can evenly bear the force from the U-shaped handle 201, preventing the U-shaped handle 201 from being squeezed and damaged between it and the storage slot 102.
[0044] Each support block 204a has a semi-circular arc surface at its bottom that fits the U-shaped handle 201, and a rubber pad 204b is fixedly connected inside the arc surface at the bottom of each support block 204a.
[0045] The semi-circular arc surface at the bottom of the support block 204a matches the shape of the U-shaped grip 201, which increases the contact area between the two and improves the stability of the support. The rubber pad 204b fixed inside the arc surface uses its own elasticity to form a buffer when the U-shaped grip 201 contacts the support block 204a, reducing the hard friction and collision noise between the two, while enhancing the anti-slip effect of the U-shaped grip 201 in the supported state.
[0046] Example 4
[0047] Reference Figure 2 This is the fourth embodiment of the present invention. Unlike the previous embodiment, each storage slot 102 has a pair of sponge pads 205 fixedly connected to its inner wall, and one side of each sponge pad 205 is an arc surface that fits the U-shaped handle 201.
[0048] When the U-shaped handle 201 is stored in the storage slot 102, the curved surface of the sponge pad 205 fits tightly against the surface of the U-shaped handle 201. Utilizing the elastic cushioning properties of the sponge, it can fill the gap between the U-shaped handle 201 and the storage slot 102, preventing the U-shaped handle 201 from generating collision noise due to shaking when stored. It can also avoid hard friction between the U-shaped handle 201 and the slot wall through flexible contact, thus protecting the U-shaped handle 201 and the inner wall of the storage slot 102.
[0049] In addition, a pair of magnetic rings 206 are fixedly connected to the inner wall of each storage slot 102, and metal blocks that attract the magnetic rings 206 are built into the corresponding positions of the two U-shaped handles 201. The magnetic rings 206 do not contact the U-shaped handles 201.
[0050] When the U-shaped grip 201 is stored in the storage slot 102, the attraction between the magnetic ring 206 and the metal block will stably attract the U-shaped grip 201 to the storage position, preventing the grip from accidentally falling out of the storage slot 102 when the pulse calibrator 101 moves or vibrates. At the same time, the magnetic ring 206 and the U-shaped grip 201 do not directly contact each other, avoiding direct impact on the magnetic ring 206 when the U-shaped grip 201 deflects into the storage slot 102.
[0051] During use, when the pulse calibrator 101 needs to be moved, the operator can rotate the U-shaped handle 201 out of the storage slot 102 to a horizontal grip position through the inclined groove 104 at the bottom of the storage slot 102. The anti-slip sleeve 203 of the horizontal grip section of the U-shaped handle 201 can enhance the friction of the hand and ensure stable force application. After being rotated out, the U-shaped handle 201 is supported by the horizontal limiting member 204. The semi-circular arc of the support block 204a, together with the rubber pad 204b, buffers and reduces shock, evenly distributing the force from the U-shaped handle 201 and preventing the handle from squeezing the inner wall of the storage slot 102.
[0052] After transportation, the U-shaped handle 201 is rotated around the shaft 202 and returned to the storage slot 102, so that there are no protruding structures on the outside of the pulse calibrator 101, reducing the space occupied. When storing, the sponge pad 205 on the inner wall of the storage slot 102 contacts the U-shaped handle 201 to prevent the U-shaped handle 201 from hitting the storage slot 102 when rotating. At the same time, the magnetic ring 206 and the metal block inside the U-shaped handle 201 generate a non-contact adsorption force to fix the U-shaped handle 201 stably in the storage position and prevent the U-shaped handle 201 from swinging back and forth when the pulse calibrator 101 is vibrated.
[0053] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
