Only by disassembling the cam group in the switch box can the adjustment be carried out, which causes inconvenience in the debugging and maintenance process. Summary of the Utility Model

[0003] The purpose of the utility model is to provide an online adjustable travel switch box component to solve the problem that in the original travel switch box component, the structural cam group is fixed and locked by nuts at both ends. Once locked, it cannot be adjusted online. Only by disassembling the cam group in the switch box can the adjustment be carried out, which causes inconvenience in the debugging and maintenance process.

[0004] To achieve the above purpose, the utility model provides the following technical scheme: An online adjustable travel switch box component, comprising a chassis and a terminal mounting plate;

[0005] The upper side of the inner wall of the chassis is provided with a terminal mounting plate, the upper end of the terminal mounting plate is provided with terminals, and the lower side of the terminal mounting plate is provided with a plurality of switch components;

[0006] The left and right ends of the lower side of the inner wall of the chassis are penetrated by a camshaft;

[0007] The outer wall of the camshaft is provided with a plurality of fixed shafts, the outer walls of the plurality of fixed shafts are all provided with cams, an adjustment shaft is arranged between the plurality of fixed shafts and the cams, a wave spring is arranged between the plurality of adjustment shafts and the inner wall of the cams, and in the working state, each cam is pressed by a single wave spring.

[0008] Preferably, mounting plate fixing parts are embedded on the outer walls of the left and right ends of the chassis, and the two mounting plate fixing parts are used to support and fix the camshaft.

[0009] Preferably, switch mounting plates are arranged on the left and right sides of the lower end of the terminal mounting plate, and the two switch mounting plates are used to fix the switch components.

[0010] Preferably, the plurality of switch components are spaced and blocked by a travel switch separator plate, and the plurality of switch components and the travel switch separator plate are fixed between the switch mounting plates by a pull rod.

[0011] Preferably, a rotating member is embedded in the right end of the chassis. A rotating rod is fixedly arranged on the outer wall of the rotating member, and the rotating rod is used to drive the rotating member to rotate.

[0012] Preferably, a connecting rod is inserted into the inner wall of the rotating member. A gear is arranged on the left side of the outer wall of the connecting rod, and the rotating rod drives the connecting rod to rotate, and the camshaft is driven to rotate through the gear.

[0013] Preferably, a pointer is arranged on the outer wall of the rotating member, and an angle marking board is arranged at the front end of the chassis. The rotation angle can be viewed through the corresponding numerical value of the pointer and the angle marking board when the rotating member rotates.

[0014] Preferably, an upper cover plate is arranged on the upper end of the chassis, and the upper cover plate is fixed to the upper end of the chassis by a plurality of bolts.

[0015] Compared with the prior art, the present utility model provides an online adjustable travel switch box assembly, which has the following beneficial effects:

[0016] The camshaft adopts a square structure, and the fixed shaft adopts the same square hole. Installing on the square camshaft can ensure that the fixed shaft cannot rotate relative to the camshaft. The cam is installed on the fixed shaft, and the end part is a tooth-shaped structure. Under the action of the compression force of the wave spring, it meshes with the tooth shape of the fixed shaft, so as to lock and fix. The adjusting shaft is installed on the fixed shaft, one end contacts with the wave spring, and the other end contacts with the end face of the next fixed shaft. Since the end face of the fixed shaft is "wavy", when the adjusting shaft rotates and contacts with the peak position of the end face of the fixed shaft, the wave spring is compressed, and the spring force presses the cam, and the tooth shape of the cam meshes with the tooth shape of the fixed shaft, and the cam and the fixed shaft are locked. When the camshaft rotates, it drives the cam to rotate.

[0017] When the adjusting shaft rotates and contacts with the valley position of the end face of the fixed shaft, the wave spring is released, the tooth shape of the cam is disengaged from the tooth shape of the fixed shaft, and the cam and the fixed shaft are separated, so that the cam angle can be freely adjusted. All the fixed shafts are installed on the camshaft. The cam is adjusted to the required position and locked by nuts at both ends. The axial position of the cam in the working state can be limited. Since each cam relies on a single wave spring for pressing in the working state, adjusting the angle of a single cam does not affect the axial and angular positions of other cams. The contact position of the travel switch can be adjusted online by rotating the camshaft, making the debugging and maintenance process more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0032] The present utility model provides as Figures 1-12An online adjustable travel switch box assembly as shown, comprising a chassis 3 and a terminal mounting plate 11;

[0033] On the upper side of the inner wall of the chassis 3, a terminal mounting plate 11 is provided. At the upper end of the terminal mounting plate 11, terminals 13 are provided. On the lower side of the terminal mounting plate 11, a plurality of switch assemblies 17 are provided;

[0034] On the lower left and right ends of the inner wall of the chassis 3, a camshaft 6 is penetrated and provided;

[0035] On the outer wall of the camshaft 6, a plurality of fixed shafts 19 are provided. On the outer walls of the plurality of fixed shafts 19, cams 18 are provided. Between the plurality of fixed shafts 19 and the cams 18, adjusting shafts 20 are provided. Between the plurality of adjusting shafts 20 and the inner walls of the cams 18, wave springs 21 are provided. In the working state, each cam 18 is pressed by a single wave spring 21.

[0036] When the adjusting shaft 20 rotates and contacts the trough position of the end face of the fixed shaft 19, the wave spring 21 is released, the tooth shape of the cam 18 is disengaged from the tooth shape of the fixed shaft 19, and the cam 18 is separated from the fixed shaft 19. Then, the angle of the cam 18 can be freely adjusted. All the fixed shafts 19 are installed on the camshaft 6. The cam 18 is adjusted to the required position and locked by nuts at both ends. In the working state, the axial position of the cam 18 can be limited. Since each cam 18 is pressed by a single wave spring 21 in the working state, adjusting the angle of a single cam 18 does not affect the axial and angular positions of other camshafts 6.

[0037] As Figure 5 and Figure 6 shown, on the outer walls of the left and right ends of the chassis 3, mounting plate fixing parts 7 are embedded. The two mounting plate fixing parts 7 are used to support and fix the camshaft 6.

[0038] The camshaft 6 is supported and fixed by the mounting plate fixing parts 7 embedded in the left and right ends of the chassis 3, and the camshaft 6 can rotate between the mounting plate fixing parts 7.

[0039] As Figure 1 and Figure 2 shown, on the left and right sides of the lower end of the terminal mounting plate 11, switch mounting plates 10 are provided. The two switch mounting plates 10 are used to fix the switch assemblies 17. Between the plurality of switch assemblies 17, they are all separated and blocked by a travel switch separator plate 8. The plurality of switch assemblies 17 and the travel switch separator plate 8 are fixed between the switch mounting plates 10 by a pull rod 9.

[0040] Install a travel switch separator plate 8 between the plurality of switch assemblies 17 and fix them in series between the switch mounting plates 10 through a pull rod 9.

[0041] As Figure 1 and Figure 2As shown in the figure, a rotating part 15 is embedded at the right end of the chassis 3. A rotating rod 5 is fixedly arranged on the outer wall of the rotating part 15. The rotating rod 5 is used to drive the rotating part 15 to rotate. A connecting rod 16 is inserted into the inner wall of the rotating part 15. A gear 14 is arranged on the left side of the outer wall of the connecting rod 16. The rotating rod 5 drives the connecting rod 16 to rotate, and drives the camshaft 6 to rotate through the gear 14.

[0042] When the camshaft 6 needs to be rotated, the rotating rod 5 drives the connecting rod 16 to rotate, and drives the camshaft 6 to rotate through the gear 14.

[0043] As Figure 1 and Figure 2 shown in the figure, a pointer 1 is arranged on the outer wall of the rotating part 15, an angle marking board 4 is arranged at the front end of the chassis 3. The rotation of the rotating part 15 can be used to view the rotation angle through the value corresponding to the pointer 1 and the angle marking board 4. An upper cover plate 12 is arranged at the upper end of the chassis 3. The upper cover plate 12 is fixed to the upper end of the chassis 3 through a plurality of bolts 2.

[0044] When the rotating rod 5 rotates left and right, the rotation angle can be viewed according to the position of the pointer 1 corresponding to the angle marking board 4. By controlling the rotation angle, the rotation of the camshaft 6 is more accurate.

[0045] The working principle of the present utility model: The rotating rod 5 drives the connecting rod 16 to rotate, and drives the camshaft 6 to rotate through the gear 14. When the rotating rod 5 rotates left and right, the rotation angle can be viewed according to the position of the pointer 1 corresponding to the angle marking board 4. When the adjusting shaft 20 rotates and contacts the trough position of the end face of the fixed shaft 19, the waveform spring 21 is released, the cam tooth profile is separated from the tooth profile of the fixed shaft 19, and the cam 18 is separated from the fixed shaft 19, then the angle of the cam 18 can be freely adjusted. All the fixed shafts 19 are installed on the camshaft 6. The cam 18 is adjusted to the required position and locked by nuts at both ends. The axial position of the cam 18 in the working state can be limited. Since each cam 18 is pressed by a single waveform spring 21 in the working state, adjusting the angle of a single cam 18 does not affect the axial direction and angle position of other camshafts 6.

[0046] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
