Description
Technical Field
[0001] The utility model belongs to the technical field of ratchet wrenches, in particular to a valve switch ratchet wrench assembly. Background Art
[0002] A ratchet wrench is a tool used to manually open and close valves. It can be a single-head ratchet wrench or a double-head multi-specification movable ratchet wrench, with a fixed hole or a movable hole. It is formed by a main plum blossom sleeve and a slave plum blossom sleeve of different sizes that are linked by bite. Because one plum blossom sleeve can have two specifications of plum blossom sets, it is more convenient to open and close valves of two different specifications, which expands the scope of use of the ratchet wrench and saves raw materials and labor costs.
[0003] The valve switch ratchet wrench assemblies currently on the market have the following two problems:
[0004] 1. During the application of traditional valve switch ratchet wrench assemblies, it is often necessary to loosen and tighten valve switches of different sizes, and the width of the wrench head is fixed, so it can only loosen and tighten valve switches of corresponding sizes. This results in the need for workers to carry tools of different specifications and sizes, which has poor compatibility during application and is time-consuming and labor-intensive;
[0005] 2. The traditional valve switch ratchet wrench assembly has a relatively simple functionality during use. It usually twists the rusted valve switch. In this case, the rust on the valve switch needs to be cleaned, which requires the staff to use other tools to complete the removal of the rusted part. The valve switch cannot be directly operated with a wrench, which is not convenient to use. Utility Model Content

[0030] The end of the wrench head 4 is fixedly connected to the handle 1, and a brush groove 17 is provided inside the handle 1. A sleeve 10 is provided inside the brush groove 17. A rotating shaft 9 is provided inside the handle 1, and the rotating shaft 9 passes through the sleeve 10. The sleeve 10 structure serves to connect the brush handle 19, making it convenient to disassemble and install the brush handle 19.
[0031] The other end of the handle 1 is fixedly connected to the ratchet head 3, and a hexagonal hole is provided inside the ratchet head 3. The structure of the ratchet head 3 can save effort when tightening or loosening the valve switch, thereby reducing the work intensity of the operator.
[0032] A storage port 12 is provided inside the wrench head 4, and an internal thread is provided inside the storage port 12. A bottle plug 15 is fixedly connected inside the wrench head 4, and the bottle plug 15 is located inside the storage port 12. Through the provided bottle plug 15 structure, when the oil bottle 13 is installed inside the storage port 12, the bottle plug 15 can be used to achieve an embedded sealing effect on the oil bottle 13, and the sealing performance is relatively strong.
[0033] A brush handle 19 is inserted into the interior of the sleeve 10, and the other end of the brush handle 19 is fixedly connected to a brush head 20. The side of the brush head 20 is connected to a fixing block 18 by bonding, and the top of the brush head 20 is fixedly connected to the bristles 11. The fixing block 18 structure makes it convenient to take out the brush when using it.
[0034] The interior of the storage port 12 is connected to the oil bottle 13 via a thread, the front end of the oil bottle 13 is provided with a bottle mouth 14, the inside of the bottle mouth 14 is inserted with a bottle plug 15, the rear end of the oil bottle 13 is fixedly connected to a cover plate 16, the outside of the oil bottle 13 is provided with an external thread, the outside of the cover plate 16 is fixedly connected to a cross block 2, and the oil bottle 13 can be easily screwed out through the provided cross block 2 structure, so that the oil bottle 13 can be conveniently disassembled and installed.
[0035] The working principle of the valve switch ratchet wrench assembly is as follows: when it is necessary to loosen or tighten the valve switch, once the valve switch is rusted or difficult to rotate, the fixing block 18 is pinched first, and then the fixing block 18 is pulled outward to rotate outward, while driving the sleeve 10 to rotate, so that the brush is rotated out, and then the brush handle 19 is taken out from the inside of the sleeve 10. Due to the structure of the sleeve 10, the brush handle 19 is connected, and then the cross block 2 is rotated to rotate the oil bottle 13 out of the storage port 12, so that it is detached from the bottle stopper 15, and then the rust removal oil is squeezed out from the bottle mouth 14 and dripped on the rusted valve switch. After waiting for the rust removal oil to completely cover the rusted part, the operator holds the brush handle 19 tightly and uses the bristles 11 on the top of the brush head 20 to clean the rust on the valve switch. The rusted part is repeatedly brushed to complete the cleaning of the rusted valve switch. In this way, there is no need for the staff to prepare cleaning tools in advance. It is better to integrate the cleaning tools on the wrench, which has strong functionality and is very convenient to use. Then when the ratchet is needed When the valve switch of different sizes is encountered, it is only necessary to change the clamping range of the wrench head 4, and the screw rod 6 is rotated during operation to drive the clamping block 5 to move forward. At the same time, the limiting rod 7 moves inside the limiting hole, thereby ensuring that the clamping block 5 will not deviate when moving. In this way, valve switches of different specifications can be clamped, and the adjustment effect of different specifications and sizes is achieved. The compatibility is strong when used. Then the staff will use the adjusted wrench head 4 to tighten it to the required tightness. When the tightening work is completed, the bottle mouth 14 is first aligned with the bottle plug 15, and then the bottle plug 15 is inserted into the bottle mouth 14 to play a role of sealing connection. Then the cross block 2 is twisted to use the thread inside the storage port 12 for rotation connection, which is convenient for the staff to take and store the oil bottle 13. Finally, the tail of the brush and the brush handle 19 are inserted into the interior of the sleeve 10, and the rotating shaft 9 is rotated to make the brush return to the interior of the brush groove 17.
