Description

Movable hook wrench

一、技术领域1. Technical field

本实用新型涉及扳手，特别涉及一种活动式勾头扳手。The utility model relates to a wrench, in particular to a movable hook head wrench.

二、背景技术2. Background technology

在离心泵的保养维修过程中，常需拆装固定轴的背帽和轴套。现有一种勾头扳手为固定式结构，其存在如下的缺点或不足：①只能在拆装同一种泵的背帽和轴套。②由于现场使用的离心泵是多种多样，现有的扳手不能适应现有的维修保养工作，需配制多种的拆装工具，在现有的勾头扳手用不上时，就用螺丝刀，扁铲和榔头相配合进行拆装，这样往往造成背帽和轴套的损坏、报废。③由于工具的不配套，还会造成操作人员的损伤，存在不安全隐患。During the maintenance and repair process of the centrifugal pump, it is often necessary to disassemble the back cap and the shaft sleeve of the fixed shaft. An existing hook wrench is a fixed structure, which has the following disadvantages or deficiencies: ① only the back cap and shaft sleeve of the same pump can be disassembled. ②Because there are many kinds of centrifugal pumps used on site, the existing wrenches cannot adapt to the existing maintenance work, and a variety of disassembly tools need to be prepared. When the existing hook wrenches are not available, use a screwdriver. The flat shovel and the hammer cooperate to disassemble and assemble, which often causes damage and scrapping of the back cap and the shaft sleeve. ③Because the tool is not matched, it will also cause damage to the operator, and there is a hidden danger of safety.

三、发明内容3. Contents of the invention

本实用新型的目的是提供一种活动式勾头扳手，采用丝杆与螺母相配合的活动式结构，既可克服或避免上述现有技术中存在的缺点或不足，又可快速、安全地完成各种型号离心泵背帽和轴套的拆装任务。The purpose of this utility model is to provide a movable hook wrench, which adopts a movable structure in which the screw rod and the nut are matched, which can not only overcome or avoid the shortcomings or deficiencies in the above-mentioned prior art, but also quickly and safely complete the hook wrench. Disassembly and assembly tasks of various types of centrifugal pump back caps and shaft sleeves.

本实用新型所述的活动式勾头扳手，包括支架、丝杆、螺母、锁头钉和手柄。所述锁头钉安装于支架的另一端，螺母安装于支架的另一端，丝杆的一端与螺母相配合，丝杆的另一端安装有手柄。The movable hook wrench described in the utility model comprises a bracket, a screw mandrel, a nut, a lock nail and a handle. The lockhead nail is installed on the other end of the bracket, the nut is installed on the other end of the bracket, one end of the screw mandrel matches the nut, and the other end of the screw mandrel is equipped with a handle.

其中，所述丝杆与螺母为公母扣啮合，转动手柄，可准确地调整丝杆顶端与锁头钉顶端的距离。Wherein, the screw rod and the nut are engaged with male and female buckles, and the distance between the top of the screw rod and the top of the lock head nail can be accurately adjusted by turning the handle.

本实用新型与现有技术相比较具有如下优点：Compared with the prior art, the utility model has the following advantages:

1、适应性广可用于各种型号的备帽和轴套的拆装操作；1. Wide adaptability can be used for disassembly and assembly of various types of spare caps and shaft sleeves;

2、由于采用活动式结构，故而操作配套、灵活、拆装速度快、效率高；2. Due to the movable structure, the operation is complete, flexible, fast in disassembly and assembly, and high in efficiency;

3、操作方便、安全。3. Easy and safe operation.
