Description

Technical Field

[0001] This utility model relates to the field of mechanical assembly technology, specifically to a positioning device for installation in confined spaces. Background Technology

[0002] When assembling the spindle, a valve core for sealing the water and air passages needs to be installed on the spindle. Since the spindle has a concave structure, its installation space is very small. At this time, people often manually press the valve core in step by step by tapping, which is very troublesome and the installation position accuracy is also uncontrollable. Therefore, it is particularly important to design a positioning device for installation in a small space to solve the above problems. Summary of the Invention

[0003] To solve the above problems, this utility model designs a positioning device for installation in confined spaces. The thrust tube, through threaded engagement, allows the valve core to be smoothly fitted onto the spindle in the main shaft within a confined space. It has the advantages of simple structure, easy manufacturing, and convenient use.

[0004] To solve the above-mentioned technical problems, this utility model provides a positioning device for installation in confined spaces, characterized in that it includes a screw, a thrust tube, a fixing block, a sleeve, a positioning screw, and a crank handle. The crank handle is L-shaped and is detachably fixed to one end of the screw. The thrust tube is installed at the other end of the screw. One end of the thrust tube has a threaded hole that matches the screw, and the other end of the thrust tube has a mandrel receiving hole that communicates with the threaded hole. The fixing block is fitted onto the outside of the screw through a threaded through hole at the center. A sleeve is connected to each of the fixing blocks on both sides of the screw. A positioning screw is installed on the end of the sleeve away from the fixing block. The fixing block is connected to the positioning connection hole on the end face of the spindle mandrel through the positioning screws on both sides.

[0005] Furthermore, a connecting hole for the crank handle to pass through is provided on the side wall of one end of the screw, and the crank handle is detachably fixed to the end of the screw by a crank handle set screw.

[0006] Furthermore, the diameter of the mandrel receiving hole is larger than the outer diameter of the mandrel in the main spindle and smaller than the outer diameter of the valve core.

[0007] Furthermore, a connecting groove for adjusting the position of the sleeve is provided on the end face of both ends of the fixed block away from the crank handle. One end of the sleeve extends into the connecting groove and is fixedly connected to the fixed block through the cooperation of screws and washers.

[0008] With the above structure, the thrust tube of this utility model can smoothly mount the valve core onto the spindle in a narrow space through threaded connection. It has the advantages of simple structure, easy manufacturing and convenient use. In addition, the position of the sleeve can be adjusted according to the actual situation, which reduces the impact of spindle machining errors on installation and increases the practical performance.

Detailed Implementation

[0013] The technical solution of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0014] In the description of this utility model, it should be noted that certain terms indicating orientation or positional relationship are only for the convenience of describing this utility model 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 utility model.

[0015] In the description of this utility model, it should be noted that the term "connection" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0016] The present invention will be further described in detail below through specific embodiments.

[0017] like Figure 1 and Figure 2The device shown is a positioning device installed in a confined space, comprising a screw 1, a thrust tube 2, a fixing block 4, a sleeve 3, a positioning screw 7, and a crank handle 9. The crank handle is L-shaped and detachably fixed to one end of the screw. The thrust tube is installed at the other end of the screw, with a threaded hole matching the screw at one end and a spindle receiving hole at the other end. The spindle receiving hole communicates with the threaded hole. The fixing block is fitted onto the outside of the screw through a threaded through hole at the center. A sleeve is connected to each of the fixing blocks on both sides of the screw. A positioning screw is installed on the end of the sleeve away from the fixing block. The fixing block is connected to the positioning connection hole 10-1 on the end face of the spindle 10 through the positioning screws on both sides. The diameter of the spindle receiving hole is larger than the outer diameter of the spindle 10-2 in the spindle 10 and smaller than the outer diameter of the valve core 11. The thrust tube of this invention, through threaded connection, allows the valve core to be smoothly fitted onto the spindle in the main shaft within a confined space. It has the advantages of simple structure, ease of manufacture, and convenient use.

[0018] like Figure 1 The screw shown has a connecting hole on the side wall of one end for the crank handle to pass through. The crank handle is detachably fixed to the end of the screw by the crank handle set screw 8.
