[0002] Polyether ether ketone is an engineering plastic, which can be applied in many fields, and the spacer sleeve of polyether ether ketone is generally used in the working scene of isolating two elements;

[0003] In the mechanical field, the connection between the shaft and the gear is generally achieved by the key and the keyway, that is, corresponding keyways are formed on the shaft and the gear, and the key is installed in the keyway, and the shaft drives the gear to rotate through the cooperation of the key and the keyway.

[0004] However, the size of the key is usually good when it is delivered from the factory, and when the size of the keyway is larger than the key, the key will shake in the keyway, so that the connection between the shaft and the gear is unstable.

[0005] However, when the size of the key is smaller than the keyway, the spacer sleeve needs to be used for connection, and the spacer sleeve is like a chain link, which needs to be connected by multiple links to form a chain, and similarly, when the distance between multiple gears is long, multiple polyether ether ketone spacer sleeves are needed to isolate the gears, and the multiple spacer sleeves need to be connected together, and the existing connection methods generally include interference fit, transition fit and gap fit, the interference fit and the transition fit need to be hammered in with external force, and although the gap fit does not need external force, the gap will cause unstable connection between the spacer sleeves, so the connection between the three spacer sleeves has certain limitations.

[0028] The socket mechanism comprises a clamping block 3, a groove larger than the clamping block 3 is formed on the spacer sleeve two 2, and the socket mechanism is inserted into the groove on the spacer sleeve two 2 through the clamping block 3, so that the spacer sleeve one 1 and the spacer sleeve two 2 are quickly and simply installed together.

[0029] In this embodiment, when two spacer sleeves need to be spliced and installed together, the clamping block 3 on the spacer sleeve one 1 is first inserted into the groove on the spacer sleeve two 2, and the spacer sleeve one 1 and the spacer sleeve two 2 can be quickly and stably installed together through the socket mechanism.

[0030] It should be noted that the clamping block 3 is arranged on the spacer sleeve one 1 and the groove is arranged on the spacer sleeve two 2, and the clamping block 3 and the groove are arranged on the spacer sleeve one 1 and the spacer sleeve two 2, respectively.

[0031] As a further scheme of the present application, the number of the clamping block 3 at one end of the spacer sleeve one 1 is set to two, and a clamping groove 301 is formed on the clamping block 3.

[0032] In this embodiment, the clamping block 3 is arranged in two on the spacer sleeve one 1, which facilitates the stable splicing of the spacer sleeve one 1 and the spacer sleeve two 2.

[0033] It needs to be noted that three or four can be set, and all are for the stable connection of the first spacer 1 and the second spacer 2.

[0034] As a further scheme of the utility model, the shell inside the groove on the second spacer 2 is provided with an inner groove 201, and the groove and the inner groove 201 are both provided with two places on the second spacer 2.

[0035] In the embodiment, the inner groove 201 in the shell of the second spacer 2 is for the activity of the socket mechanism inside the inner groove 201 to complete the quick splicing.

[0036] As a further scheme of the utility model, the inner groove 201 is provided with a pressure bearing block 4, the pressure bearing block 4 is in sliding cooperation with the second spacer 2, and the pressure bearing block 4 is also in sliding cooperation with the clamping block 3.

[0037] In the embodiment, when the clamping block 3 is inserted into the groove of the second spacer 2, the bottom of the clamping block 3 starts to extrude the pressure bearing block 4, and when the bottom of the clamping block 3 starts to extrude the pressure bearing block 4, the pressure bearing block 4 moves to both sides horizontally inside the inner groove 201 due to the inclined surface of the pressure bearing block 4.

[0038] As a further scheme of the utility model, the number of the pressure bearing block 4 inside one inner groove 201 is two, and the two pressure bearing blocks 4 are symmetrically distributed with respect to the groove on the second spacer 2.

[0039] In the embodiment, the clamping block 3 extrudes the pressure bearing blocks 4 on both sides, so that the pressure bearing blocks 4 move to both sides horizontally inside the inner groove 201.
