Description

Technical Field

[0001] The utility model relates to the field of sealing strip butt joint, in particular to a sealing strip butt joint device. Background Art

[0002] Sealing strips are strips made of rubber and are installed at the joint of two components. They can prevent leakage or intrusion of internal and external media (rain, air, dust, etc.), and can prevent or reduce damage caused by mechanical vibration and impact, thereby achieving the effects of sealing, sound insulation, heat insulation and shock absorption. Sealing strips are elastic strips or rod-shaped materials. Sealing strips can be connected to form longer strips, which can seal longer joints.

[0003] Existing sealing strip docking devices, such as the sealing strip docking device proposed in patent application number "CN201920039725.X", use structures such as an insertion rod, a lower fixing part, an upper fixing part, a locking mechanism, a fixing groove, and a docking plate to insert the insertion rod into the end of the sealing strip to connect the two ends of the sealing strip. At the same time, the barbs on the insertion rod hook the end of the sealing strip to avoid breakage from the docking interface and ensure a stable connection.

[0004] However, the ends of the sealing strips are fixed by butting them together through the barbs of the insertion rod, resulting in poor elasticity and plasticity of the butting parts, and the parts connected by the barbs will be damaged and easily broken. Therefore, a sealing strip butt joint device is proposed. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] A sealing strip docking device, such as Figure 1-Figure 4 As shown, it includes a base 1, the upper end of which is fixedly connected to a top plate 2, the base 1 and the top plate 2 form a frame assembly of the docking device, the middle part of the base 1 is vertically slidably connected to a support rod 4, the side wall of the support rod 4 is sleeved with a spring 5, one end of the spring 5 is fixedly connected to the lower end of the base 1, and the other end is fixedly connected to the side wall of the support rod 4, heating tubes 8 are fixedly connected to both sides of the upper end of the support rod 4, and two groups of clamping assemblies for docking rubber strips are symmetrically slidably connected to the top plate 2, and the two groups of clamping assemblies correspond to the two groups of heating tubes 8 respectively.

[0024] By fixing the two groups of sealing strips in the two groups of clamping components, the centers of the two groups of clamping components are opposite to each other, and the spring 5 pushes the support rod 4 to lift, so that the heating tubes 8 on both sides of the upper end of the support rod 4 are opposite to the two groups of clamping components, and the heating tubes 8 are energized to heat the ends of the two groups of sealing strips to a molten state, and the support rod 4 is controlled to descend, and the spring 5 is squeezed to make the heating tube 8 descend and detach from the middle of the two groups of clamping components. The two groups of clamping components control the two groups of sealing strips to approach docking, so that the ends of the sealing strips in the molten state are docked, and the ends of the sealing strips will not be damaged. The elasticity and plasticity of the docking parts are relatively high.

[0025] Two groups of electro-hydraulic push rods 3 are fixedly connected to the inner bottom wall of the base 1 , and the two groups of electro-hydraulic push rods 3 are symmetrically located on both sides of the support rod 4 . The output ends of the two groups of electro-hydraulic push rods 3 are commonly fixedly connected to a support plate 6 , and the support rod 4 runs through the middle of the support plate 6 .

[0026] like Figure 1-Figure 2 As shown, the electro-hydraulic push rod 3 (model DYTP450-110) can drive the support plate 6 to move up and down. When the support plate 6 descends, it can squeeze the side wall of the support rod 4 to control the support rod 4 to descend.

[0027] Two groups of partitions 7 are vertically fixed to the upper end of the support plate 6. The two groups of partitions 7 are symmetrically located on both sides of the upper end of the support rod 4, and the two groups of partitions 7 are located between the heating tube 8 and the clamping assembly.

[0028] like Figure 1-Figure 2 As shown, the lifting of the support plate 6 can drive the lifting of the two groups of partitions 7, so that the partitions 7 isolate the clamping assembly and the heating tube 8. When the partitions 7 are lifted, the end of the sealing strip abuts against the partitions 7, and the length of the partition 7 sealing strip penetrating the clamping assembly can be controlled. The partitions 7 are lowered, and the heating tube 8 heats the end of the sealing strip.

[0029] The clamping assembly includes a push plate 10, a slide groove 20 is opened on the top plate 2, the push plate 10 is slidably connected in the slide groove 20, a double-axis cylinder 9 is fixedly connected to the middle of the upper end of the top plate 2, and the two ends of the double-axis cylinder 9 are respectively fixedly connected to the push plates 10 of the two groups of clamping assemblies.

A spring 2 19 is fixedly connected between the end of the connecting rod 17 and the upper end of the clamping plate 15. The spring 2 19 is sleeved on the connecting rod 17.

[0032] like Figure 1-Figure 4 As shown, the two groups of clamps 15 are separated in the fixed frame 11, and the end of the sealing strip is inserted into the two groups of clamps 15 in the fixed frame 11 until the end of the sealing strip abuts against the partition 7 and the insertion is stopped. Then, the two groups of clamps 15 are squeezed by the spring 2 19, so that the two groups of clamps 15 squeeze the sealing strip, so that the clamping assembly can drive the sealing strip to move.

[0033] An L-shaped plate 12 is fixedly connected to one side of the fixing frame 11 , a pull rod 13 is slidably connected to the L-shaped plate 12 , a triangular block 14 is fixedly connected to one end of the pull rod 13 , and the triangular block 14 is pressed and matched with two groups of clamping plates 15 .

[0034] like Figure 4 As shown, by pressing the pull rod 13, the end of the triangular block 14 can squeeze the two groups of clamps 15, so that the two groups of clamps 15 are separated, which is convenient for inserting the sealing strip into the fixed frame 11. The triangular block 14 is pulled out of the fixed frame 11, and the two groups of clamps 15 squeeze and fix the sealing strip under the action of the spring 19.
