DETAILED DESCRIPTION

[0022] The utility model will be further described in detail below in combination with the drawings and specific embodiments.

[0023] Embodiment 1

[0024] As shown in Figure 1 and 2As shown, the embodiment provides an integrated water supply pipeline valve opening and closing device, which comprises a wrench head, a connecting rod 2 and a handle 3 that can be connected to each other. The wrench head has two types of square pin wrench head 11 and hand wheel wrench head 12, and the connecting rod 2 has a plurality of rods that can be connected end to end. The overall use principle of the device is as follows: according to whether the hand wheel is installed on the valve, select the square pin wrench head 11 or the hand wheel wrench head 12; according to the depth of the position where the valve is located, select the corresponding number of connecting rods 2; then connect the selected wrench head, the corresponding number of connecting rods 2 and the handle 3 in sequence to assemble a complete tool, which can be used to open and close the valve. It should be noted that if the valve is close to the operator, the wrench head and the handle 3 can be directly assembled and connected without the connecting rod 2.

[0025] As shown in Figure 3 The square pin wrench head 11 comprises a disc body 111 and four square pin holes 1111 of different sizes provided on the disc body 111. In the embodiment, the side lengths of the four square pin holes 1111 are 30mm, 40mm, 45mm and 55mm respectively, so as to meet the opening and closing requirements of commonly used caliber water supply pipeline valves, ensure the accurate cooperation of the square pin wrench head with square pins of various sizes, and improve the operation efficiency. In use, the corresponding square pin hole 1111 on the disc body 111 is sleeved on the valve square pin, the disc body 111 is rotated around the valve square pin as the axis, the valve square pin is driven to rotate, and the opening and closing of the valve is realized. In order to ensure the structural strength of the disc body 111, the four square pin holes 1111 are uniformly distributed around the middle part of the disc body, and the middle part of the disc body is used to connect the handle 3 or the connecting rod 2.

[0026] As shown in Figure 1 In order to facilitate the connection of the disc body 111 with the connecting rod 2 or the handle 3, the disc body 111 is provided with a first assembly rod 112 in the middle part. The first assembly rod 112 is assembled and connected with the connecting rod 2 or the handle 3, so that the first assembly rod 112 can adopt the same connection structure as the connecting rod 2, and the connection operation is more unified and convenient. Generally, one end of the first assembly rod 112 can be designed as a solid structure, and a screw hole is arranged at the end, while a connecting hole is arranged in the middle part of the disc body 111 to realize the stable connection of the two through bolts, and also facilitate disassembly and storage.

[0027] As shown in Figure 2As shown, the hand wheel wrench head 12 comprises a crossbar 121, two insertion rods 122 vertically arranged on one side of the crossbar 121, and a second assembly rod 123 vertically arranged at the middle of the other side of the crossbar 121. The second assembly rod 123 has the same function as the first assembly rod 112, and is also used to adopt a unified rod and rod connection structure to facilitate the connection operation of the hand wheel wrench head 12 and the connecting rod 2 or the handle 3. In use, the two insertion rods 122 are respectively inserted into the holes at the opposite positions of the valve hand wheel, the second assembly rod 123 is rotated, and the two insertion rods 122 rotate around the second assembly rod 123 as the axis to drive the valve hand wheel to rotate, thereby realizing the opening and closing of the valve. It should be noted that since the hole on the valve hand wheel is relatively large, a hand wheel wrench head of a certain size can be used for valve hand wheels of various sizes. In this embodiment, the distance between the two insertion rods 122 is preferably 15 cm.

[0028] As shown in Figure 1 and 2 The handle 3 comprises a hand holding rod 31 and a third assembly rod 32 vertically arranged at the middle of the hand holding rod 31. The hand holding rod 31 facilitates the force exerted by the operator, and the third assembly rod 32 has the same function as the first and second assembly rods, which are used to adopt a unified rod and rod connection structure to facilitate the connection operation of the handle and the connecting rod or the wrench head.

[0029] The plurality of connecting rods 2 can have the same length, for example, 1 m, or different lengths to assemble the most suitable length, taking into account the operation convenience and weight.

[0030] The connection structure between the above wrench head, connecting rod 2 and handle 3 can adopt the following manner: the end portions of the rods are inserted into each other through the cooperation of the inner and outer diameters, and the insertion part is connected and fastened by bolts and nuts to ensure stable transmission of torque. For example, the insertion end outer diameter of the first assembly rod 112 and the second assembly rod 123 is a, the insertion end inner diameter of the third assembly rod 23 is a, and the inner diameter of one end of the connecting rod 2 is a and the outer diameter of the other end is a. Generally, only the pipe diameter at the outer diameter a can be reduced to form a limiting step on the outer side of the rod, so that the overall outer diameter of the first and second assembly rods is A, and only the end portion has an outer diameter of a, so that only the end portion can be inserted into the connecting rod 2 or the third assembly rod 23, so that the hole for bolt and nut connection can be quickly aligned. Further, one side of the insertion part of the rods can be designed as a plane, so that the insertion angle of the two rods is fixed, that is, after insertion, the holes between the two rods are automatically aligned.

[0031] Embodiment 2

[0032] On the basis of embodiment 1, considering some special cases, the valve and the operator are not in a direct relationship, and the orientation of the wrench head may need to be changed to perform the opening and closing operation. Therefore, the device can also comprise, as shown in Figure 4The turning lever 4 shown comprises two parts perpendicular to each other, and the connecting structure at both ends is consistent with the connecting rod 2, and can be connected between the wrench head and the connecting rod 2, or between the wrench head and the handle 3, or even between the connecting rod 2 and the handle 3, so that the orientation of the wrench head is perpendicular to the third assembling rod 32 of the handle 3, and the operation requirement in special cases is met.

[0033] The above is only a preferred specific embodiment of the present application, which is an implementation based on the overall concept of the present application, and the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
