Description

Technical Field

[0001] The utility model relates to a support rod structure with taper welding. Background Art

[0002] At present, many strut structure motors on the market are fixed with metal tube buckling structures, which have problems such as unstable metal tube buckling dimensions, poor tensile strength, easy breakage, and poor sealing. Secondly, due to the parameter error of the buckling machine, it will also lead to insufficient sealing at the buckling position, and the buckle is a one-time seal, so the sealing effect is relatively poor.

[0003] Based on the above problems, we designed a support rod structure with tapered welding that has higher sealing performance. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a support rod structure with taper welding and high sealing performance.

[0005] The utility model is realized by the following technical solutions:

[0006] A support rod structure with tapered welding includes a lower ball seat assembly, an outer sleeve, a damper housing, a thick duct assembly, a gear box rubber sleeve, a gear box and a motor rubber sleeve. The lower ball seat assembly, the motor rubber sleeve, the gear box, the gear box rubber sleeve, the damper housing and the thick duct assembly are assembled in sequence from bottom to top, and the outer sleeve is assembled downward from the top of the thick duct assembly. After assembly, a tapered seal is formed between the thick duct assembly, the damper housing and the lower ball seat assembly.

[0007] Preferably, the lower ball seat assembly has a first outer cone surface, the damper housing has a second outer cone surface, and the thick conduit assembly has a third outer cone surface, and the diameters of the first outer cone surface, the second outer cone surface and the third outer cone surface gradually increase downward; after the outer sleeve is assembled from the top to the bottom, it forms a seal with the first outer cone surface, the second outer cone surface and the third outer cone surface respectively.

[0008] Preferably, the upper end diameter of the first outer cone surface is larger than the lower end diameter of the second outer cone surface, and the upper end diameter of the second outer cone surface is larger than the lower end diameter of the third outer cone surface.

[0009] Preferably, the interior of the outer sleeve is processed to match the first inner cone surface of the first outer cone surface, the second inner cone surface of the second outer cone surface, and the third inner cone surface of the third outer cone surface. After the outer sleeve is assembled from top to bottom, the first outer cone surface and the first inner cone surface are matched to form a seal, the second outer cone surface and the second inner cone surface are matched to form a seal, and the third outer cone surface and the third inner cone surface are matched to form a seal.

[0010] Preferably, the first outer conical surface and the first inner conical surface are interference fit, and a secondary seal is formed at the fitting position after laser welding.

[0011] Preferably, the second outer conical surface and the second inner conical surface are interference fit, and a secondary seal is formed at the fitting position after laser welding.

[0012] Preferably, the third outer cone surface and the third inner cone surface are interference fit, and a secondary seal is formed after laser welding at the fitting position.

[0013] The beneficial effect of the utility model is that in the device, the outer sleeve is installed from top to bottom. After installation, three sealing positions from top to bottom are formed by the cooperation of the outer cone surface and the inner cone surface, thereby achieving a higher waterproof effect and extending the service life of the support rod structure. Compared with the press buckle, the support rod structure under this installation method has higher tensile strength and higher sealing, and is suitable for popularization and use.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 8 A support rod structure with tapered welding is shown, comprising a lower ball seat assembly 1, an outer sleeve 2, a damper housing 3, a thick duct assembly 4, a gear box rubber sleeve 5, a gear box 6 and a motor rubber sleeve 7. The lower ball seat assembly 1, the motor rubber sleeve 7, the gear box 6, the gear box rubber sleeve 5, the damper housing 3 and the thick duct assembly 4 are assembled in sequence from bottom to top, and the outer sleeve 2 is assembled downward from the top of the thick duct assembly 4. After assembly, a tapered seal is formed between the thick duct assembly 4, the damper housing 3 and the lower ball seat assembly 1 respectively.

[0029] In the above technical scheme, first complete the assembly of the lower ball seat assembly 1, the motor rubber sleeve 7, the gear box 6, the gear box rubber sleeve 5, the damper housing 3 and the thick pipe assembly 4, and finally install the outer sleeve 2 from the top to the bottom, rely on the conical surface contact to form a self-seal, and then use laser welding to form a fixation and secondary seal.

[0030] See also Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the lower ball seat assembly 1 has a first outer cone surface 101, the damper housing 3 has a second outer cone surface 301, and the thick conduit assembly 4 has a third outer cone surface 401. The diameters of the first outer cone surface 101, the second outer cone surface 301 and the third outer cone surface 401 gradually increase downward; after the outer sleeve 2 is assembled from the top to the bottom, it forms a seal with the first outer cone surface 101, the second outer cone surface 301 and the third outer cone surface 401 respectively.

[0031] The diameters of the first outer conical surface 101 , the second outer conical surface 301 and the third outer conical surface 401 all increase downward, thereby facilitating the installation of the outer sleeve 2 from the top downward.

[0032] See also Figure 6 and Figure 7 As shown, the upper end diameter of the first outer cone surface 101 is larger than the lower end diameter of the second outer cone surface 301 , and the upper end diameter of the second outer cone surface 301 is larger than the lower end diameter of the third outer cone surface 401 .

[0033] This technical solution facilitates the assembly of the outer sleeve 2 from top to bottom and avoids the jamming phenomenon.

[0034] See also Figure 6 and Figure 7 As shown, the internal processing of the outer sleeve 2 matches the first inner cone 221 of the first outer cone 101, the second inner cone 222 matches the second outer cone 301, and the third inner cone 223 matches the third outer cone 401. After the outer sleeve 2 is assembled from top to bottom, the first outer cone 101 and the first inner cone are matched to form a seal, the second outer cone 301 and the second inner cone are matched to form a seal, and the third outer cone 401 and the third inner cone are matched to form a seal.

[0035] The first outer cone surface 101 and the first inner cone surface 221 are interference fit, and a secondary seal is formed after laser welding at the matching position. The second outer cone surface 301 and the second inner cone surface 222 are interference fit, and a secondary seal is formed after laser welding at the matching position. The third outer cone surface 401 and the third inner cone surface 223 are interference fit, and a secondary seal is formed after laser welding at the matching position.

[0036] Each outer cone surface and inner cone surface are fitted with interference fit. After interference fit, the outer cone surface and the inner cone surface maintain contact and produce a sealing effect. After laser welding, the outer sleeve 2 is fixed to the lower ball seat assembly 1, the damper housing 3 and the thick pipe assembly 4 respectively, and a secondary seal is formed to further enhance the sealing effect.

[0037] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
