AI Technical Summary
During the use of the paste pump, the bolts on the sensing ring are prone to loosening, causing the sensing ring to shift and resulting in the proximity switch colliding and damaging the sensing ring, thus affecting the normal operation of the equipment.
A swing arm mechanism is used as a transfer mechanism. When the contact block comes into contact with the contact ring, the proximity switch is triggered, avoiding direct collision between the sensing ring and the proximity switch. The deflection of the swing arm mechanism triggers the proximity switch, replacing the direct triggering method of the sensing ring.
This effectively avoids collisions between the sensing ring and the proximity switch, ensuring the normal operation of the proximity switch and extending the service life of the equipment.

[0026] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. The embodiments in the application and the features in the embodiments can be combined with each other without conflict. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.
[0027] Please refer to Figs. 1-3 The utility model discloses a paste pump proximity switch anti -collision mechanism sets up on the pump body 1, including:
[0028] The pump body 1 is opened in extension groove 11, the pump body 1 is provided with plunger 12, plunger 12 is provided with the contact ring 121 on it;
[0029] Proximity switch 2, proximity switch 2 sets up on the pump body 1;
[0030] Swing arm mechanism 3, swing arm mechanism 3 rotation sets up on the pump body 1;
[0031] One end of swing arm mechanism 3 extends to the pump body 1 through extension groove 11 and is provided with contact block 33, to contact with contact ring 121;
[0032] The other end of swing arm mechanism 3 is provided with the induction block 31 and the slot 32 corresponding with proximity switch 2, the induction block 31 is used to trigger proximity switch 2 when contact block 33 and contact ring 121 contact.
[0033] The application replaces the setting mode of proximity switch 2 and the induction ring provided on plunger 12 by the transmission of swing arm mechanism 3 to trigger proximity switch 2 when using, which can effectively avoid the collision between the induction ring and proximity switch 2 caused by the shortening of the distance between them due to loosening.
[0034] Specifically, swing arm mechanism 3 is in a vertical state under the influence of gravity when it is not in contact with contact ring 121, and the slot 32 provided thereon corresponds to proximity switch 2 at this time, and the induction block 31 is misaligned with proximity switch 2, so proximity switch 2 is not triggered. When contact block 33 contacts contact ring 121 with the movement of plunger 12, swing arm mechanism 3 is deflected, and proximity switch 2 is triggered through induction block 31. The above-mentioned mode uses swing arm mechanism 3 as a transfer mechanism to avoid the collision of proximity switch 2.
[0035] It is easy to think that the pump body 1 is provided with a bearing bracket 4, and the swing arm mechanism 3 is provided with a connecting shaft 34 corresponding to the bearing bracket 4.
[0036] In order to avoid the swing arm mechanism 3 from deflecting excessively, or swinging when the plunger 12 is reset, causing the inductive block 31 to be triggered by mistake, a limiting block corresponding to the swing arm mechanism 3 is arranged on the bearing bracket 4, and the bearing bracket 4 and the limiting block are combined in an L shape.
[0037] Further, in order to avoid the material in the pump body 1 from affecting the reset of the swing arm mechanism 3, a reset torsion spring is arranged between the bearing bracket 4 and the swing arm mechanism 3 in a preferred embodiment.
[0038] In order to reduce the impact received by the swing arm mechanism 3 and improve the service life of the anti-collision structure, a contact pad corresponding to the swing arm mechanism 3 is arranged on the limiting block.
[0039] It is easily conceivable that the contact block 33 is a counterweight block for driving the swing arm mechanism 3 to reset after deflection.
