Description

Technical Field

[0001] This invention relates to the field of gun head handling equipment, and more particularly to a gun head handling equipment. Background Technology

[0002] Currently, most pipette tip dispensers on the market are mechanical, which is bulky, expensive, and adds load to the crossarm. The rigid insertion of the tip compromises sealing, leading to errors in reagent dispensing. Furthermore, the tip is prone to falling off during operation, disrupting the entire experimental process and progress. Utility Model Content

[0003] In order to solve one or more technical problems existing in the prior art, the purpose of this application is to provide a gun head removal device, in which the expansion tube moves downward and squeezes the expansion ring to expand outward when the gun head is inserted, so that the gun head is fixed and perfectly sealed.

[0004] To address the aforementioned technical problems, one of the objectives of this application is achieved through the following technical solution: A gun tip retrieving device includes an expansion gun tip module outer frame, a push gun tip tube extending through the side of the expansion gun tip module outer frame, an expansion tube inserted into the push gun tip tube, and an expansion rubber ring inserted into the push gun tip tube, the expansion rubber ring being sleeved on the expansion tube.

[0005] Furthermore, a pushing component is provided inside the outer frame of the expansion gun head module, which pushes the expansion tube.

[0006] Furthermore, the pushing component includes an electric telescopic rod fixedly installed within the outer frame of the expansion gun head module, and an L-shaped connecting block is fixedly provided at the output end of the electric telescopic rod, the L-shaped connecting block being fixedly connected to the expansion tube.

[0007] Furthermore, a control module is fixedly mounted on the outer frame of the expansion gun head module, and the electric telescopic rod is electrically connected to the control module.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: (1) The nozzle removal device has an expansion ring at the tip insertion point, which is embedded between the fixing nut and the expansion sleeve. The expansion tube can move up and down. When inserting the nozzle, the expansion tube moves downward to compress the expansion ring and expand outward, thus fixing the nozzle and sealing it perfectly. When the nozzle is removed, the expansion tube moves upward, the expansion ring returns to its original position, and the nozzle is pushed down, causing the nozzle to fall off.

[0010] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0011] In the description of this application, it should be understood that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0012] The terms "first," "second," etc., used in this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class, not limited in number; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates an "or" relationship between the preceding and following objects as a type of gun-head handling device.

[0013] Example 1: As Figure 1 As shown, a gun tip retrieving device includes an expansion gun tip module outer frame 10. A push gun tip tube 5 is provided through the side of the expansion gun tip module outer frame 10. An expansion tube 6 is inserted into the push gun tip tube 5, and an expansion rubber ring 7 is also inserted into the push gun tip tube 5. The expansion rubber ring 7 is sleeved on the expansion tube 6. A pushing component is provided inside the expansion gun tip module outer frame 10, which pushes the expansion tube 6. The pushing component includes an electric telescopic rod 1 fixedly installed inside the expansion gun tip module outer frame 10. An L-shaped connecting block 3 is fixedly installed at the output end of the electric telescopic rod 1, and the L-shaped connecting block 3 is fixedly connected to the expansion tube 6. A control module is fixedly installed on the expansion gun tip module outer frame 10, and the electric telescopic rod 1 is electrically connected to the control module. In this gun tip retrieving device, an expansion rubber ring 7 is made at the tip insertion point. It is embedded between the fixing nut and the expansion sleeve. The expansion tube 6 can move up and down. When inserting the gun tip, the expansion tube 6 moves downward, squeezing the expansion rubber ring 7 to expand outward, thus fixing the gun tip and sealing it perfectly. When the gun head is knocked off, the expansion tube 6 moves upward, the expansion rubber ring 7 returns to its original position, the gun head tube 5 is pushed downward, and the gun head falls off.

[0014] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
