Description

Technical Field

[0001] The utility model belongs to the technical field of water pump assembly and relates to a control barrel hook structure. Background Art

[0002] During the installation of the existing water pump, the control barrel assembly needs to be placed on the connection end of the water inlet section before continuing the assembly. Since there is an O-ring between the control barrel assembly and the water inlet section, the O-ring will be squeezed after the control barrel assembly is placed on the connection end of the water inlet section. During the assembly process, the elastic force generated by the squeezed O-ring will in turn act on the control barrel assembly and the water inlet section, which can easily cause the control barrel assembly and the water inlet section to shift or detach, thereby affecting the sealing effect and installability. Utility Model Content

[0003] The utility model aims at the deficiencies of the prior art and provides a control barrel hook structure, which can improve the sealing effect and installability of the control barrel assembly and the water inlet joint.

[0004] In order to solve the above technical problems, the purpose of the utility model is achieved through the following technical solutions:

[0005] A control barrel hook structure comprises a control barrel assembly and a water inlet joint, wherein the control barrel assembly and the water inlet joint are connected via a hook assembly to form a pre-installed structure, wherein the hook assembly comprises a connecting rod hook, an elastic limit block and a locking mechanism, wherein the elastic limit block is adapted to the upper end cavity of the control barrel assembly and is limited by a step, wherein the connecting rod hook penetrates downwardly through the control barrel assembly and contacts the bottom of the connecting end of the water inlet joint via a bent hook at the end, and wherein the locking mechanism is fixedly connected to the connecting rod hook and presses the elastic limit block downward.

[0006] In the above-mentioned control barrel hook structure, the step is an axial limiting step formed in the upper end cavity of the control barrel assembly, and the bottom of the elastic limiting block abuts against the limiting step to form a limiting structure.

[0007] In the above-mentioned control barrel hook structure, the locking mechanism is a quick clamp.

[0008] In the above-mentioned control barrel hook structure, further, the quick clamp includes a fixed rod and a handle hinged on the fixed rod, the bottom of the fixed rod is fixedly connected to the upper end of the connecting rod hook, and the elastic limit block is sleeved on the fixed rod and fixedly connected thereto.

[0009] In the above-mentioned control barrel hook structure, an internal threaded hole is provided at the bottom of the fixing rod, and the screw structure at the upper end of the connecting rod hook is screwed and fixed thereto; a connecting screw sleeve is provided on the outer sleeve of the fixing rod, and the connecting screw sleeve is screwed and fixed to the center hole of the elastic limit block; the fixing rod can also be fixedly connected to the center hole of the elastic limit block by an interference fit or a limiting structure.

[0010] In the above-mentioned control barrel hook structure, the connecting rod hook is axially adjustable and screwed to the fixed rod, and a locking nut for locking the screw connection structure is sleeved on the connecting rod hook. The relative position between the screw structure and the internal threaded hole of the fixed rod can be adjusted by rotating the connecting rod hook, thereby adjusting the axial distance between the elastic limit block and the hook. Preferably, in the initial state, when the bottom of the elastic limit block contacts the step, the hook contacts the bottom of the connection end of the water inlet section.

[0011] In the above-mentioned control barrel hook structure, the elastic limit block is made of a polymer elastic material in the art, preferably a nylon limit block.

[0012] In the above-mentioned control barrel hook structure, other locking mechanisms can also be used. For example, the upper end of the connecting rod hook is a screw structure and passes through the elastic limit block. A locking nut is threaded on the screw structure.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] The utility model provides a control barrel hook structure. Before installation, the control barrel assembly and the water inlet joint form a firm pre-installed structure through the hook assembly composed of a connecting rod hook, an elastic limit block and a locking mechanism. During assembly, the control barrel assembly and the water inlet joint will not be displaced or separated due to the influence of the O-ring. After assembly, the hook assembly can be easily removed. The hook assembly of the utility model is installed by using the cavity structure of the control barrel assembly and the water inlet joint itself, which will not affect the assembly process of the water pump. The control barrel hook structure provided by the utility model can improve the sealing effect and installability of the control barrel assembly and the water inlet joint after installation.

[0020] The present invention will be further described below with reference to the accompanying drawings. Figure 1-3 :

[0021] A control barrel hook structure includes a control barrel assembly 1 and a water inlet section 2, wherein the control barrel assembly 1 and the water inlet section 2 are connected via a hook assembly to form a pre-installed structure, wherein the hook assembly includes a connecting rod hook 3, an elastic limit block 4 and a locking mechanism, wherein the elastic limit block 4 is adapted to the upper end cavity of the control barrel assembly 1 and is limited by a step 5, wherein the connecting rod hook 3 penetrates downward through the control barrel assembly 1 and contacts the bottom of the connecting end 7 of the water inlet section 2 via a bent hook 6 at the end, wherein the locking mechanism is fixedly connected to the connecting rod hook 3 and presses the elastic limit block 4 downward.

[0022] During installation, assemble the control barrel assembly 1 and the water inlet section 2 together, then pass the loosened hook assembly through the cavity of the control barrel assembly 1 until the elastic limit block 4 matches the upper cavity. The bottom of the elastic limit block 4 contacts the axial limit step 5 in the upper cavity of the control barrel assembly 1 to form an axial limit structure. Then rotate the angle left and right to make the hook 6 enter the position corresponding to the bottom of the connecting end 7 of the water inlet section 2. Finally, use the locking mechanism to press the elastic limit block 4 downward. The elastic limit block 4 and the hook 6 clamp the control barrel assembly 1 and the water inlet section 2 to form a firm pre-installed structure. Check whether there is a gap between the control barrel assembly 1 and the water inlet section 2. If there is no gap, install it in place. After that, you can assemble the water pump. After assembly, loosen the locking mechanism, rotate it and take out the hook assembly.

[0023] In this embodiment, the locking mechanism is a quick clamp.

[0024] Its specific structure is: the quick clamp includes a fixed rod 8 and a handle 9 hinged on the fixed rod 8, the bottom of the fixed rod 8 is fixedly connected to the upper end of the connecting rod hook 3, the elastic limit block 4 is sleeved on the fixed rod 8 and fixedly connected thereto, and by pulling the handle 9, the quick frame presses the elastic limit block 4 downward to form a clamping structure that cooperates with the bent hook 6.

[0025] In order to better connect the various components of the hook assembly into a whole: an internal threaded hole is provided at the bottom of the fixing rod 8, and the screw structure at the upper end of the connecting rod hook 3 is screwed and fixed thereto; a connecting screw sleeve 10 is provided on the outer sleeve of the fixing rod 8, and the connecting screw sleeve 10 is screwed and fixed to the center hole of the elastic limit block 4; the fixing rod 8 can also be fixedly connected to the center hole of the elastic limit block 4 by an interference fit or a limiting structure.

[0026] This embodiment further provides an adjustment structure of the hook assembly: the connecting rod hook 3 is axially adjustable and screwed to the fixing rod 8, and a locking nut 11 of a locking screw connection structure is sleeved on the connecting rod hook 3. The relative position between the screw structure and the internal threaded hole of the fixing rod 8 can be adjusted by rotating the connecting rod hook 3, thereby adjusting the axial distance between the elastic limit block 4 and the hook 6. Preferably, in the initial state, when the bottom of the elastic limit block 4 contacts the step 5, the hook 6 contacts the bottom of the connection end 7 of the water inlet section 2.

[0027] The elastic limit block 4 is made of a polymer elastic material in the art, preferably a nylon limit block.

[0028] In order to form a more stable pre-installed connection structure, the elastic limit block 4 and the connecting rod hook 3 are coaxially arranged with the cavity of the control barrel assembly 1 .
