Description

Technical Field

[0001] The utility model relates to the technical field of pin installation cones, in particular to an installation cone for a gear protection ring. Background Art

[0002] The gear guard is a protective device that fits over the gear to prevent damage caused by collisions between gear teeth. To install the guard, first install the locking pins in the mounting holes of the locking plate and the guard. The locking plate is then attached to the mounting sleeve via the locking pins. Finally, the guard is locked in place using the locking plate.

[0003] In the process of installing the locking pin into the mounting holes of the locking plate and the protective cover, the existing method is generally to install it manually. Since the head and tail of the locking pin are larger than the diameter of the mounting hole, the installation is more complicated, resulting in low efficiency of installing the locking pin into the mounting hole, which in turn affects the efficiency of subsequent installation of the protective cover. Utility Model Content

[0004] In view of the above problems, the present utility model is proposed to provide a mounting cone for a gear protection ring that overcomes the above problems or at least partially solves the above problems, and can solve the problem of low installation efficiency of the locking pin of the existing gear protection sleeve, thereby achieving the effect of improving the efficiency of installing the locking pin in the corresponding mounting hole.

[0005] Specifically, the utility model provides a mounting cone for a gear protection ring, and the mounting cone for the gear protection ring includes:

[0006] A tapered rod, comprising a handheld operating portion and a mounting portion;

[0007] A cone head, wherein the cone head is provided with a placement portion, a return hook plate and a connecting portion; the connecting portion is connected to the mounting portion; the placement portion is provided with a placement cavity extending along the axial direction of the cone head; the placement portion is provided with a first notch extending outward from the placement cavity along the radial direction of the cone head; the return hook plate is located between the placement portion and the connecting portion; the return hook plate and the first notch are arranged opposite to each other with respect to the axis of the cone head; one end of the return hook plate is connected to the placement portion, and the other end is fixed to the connecting portion; the width of the return hook plate is smaller than the diameter of the placement portion.

[0008] Optionally, the thickness of the return hook plate is smaller than the wall thickness of the placement portion.

[0009] Optionally, a plug-in slot is provided on the connecting portion; the connecting portion is sleeved on the mounting portion through the plug-in slot, and the connecting portion is detachably connected to the mounting portion by thread.

[0010] Optionally, the end of the placement portion connected to the return hook plate is the rear end; and the front end of the placement portion is provided with a pointed end.

[0011] Optionally, an outward expansion portion is provided on the outer side of the placement portion; the outward expansion portion is used to make the diameter of the placement portion first increase and then decrease from the front end to the rear end along its axial direction, so that the diameter of the middle part of the placement portion is larger than the diameters of the front and rear ends.

[0012] In the installation cone of the gear protection ring of the present invention, the first notch is used to place the pin of the locking pin in the placement groove, so that the locking pin can be quickly installed. The placement groove runs through the front and back along the axial direction of the placement portion, and the front end of the placement groove is the front end of the cone head. When the locking pin is installed in the placement groove, the pin head of the locking pin extends forward from the front end of the placement groove, and the pin tail successively extends from the rear end of the placement groove. The return hook plate and the rear end of the placement portion form a return hook, and the pin tail of the locking pin is placed on the return hook plate. Since the width of the return hook plate is smaller than the diameter of the placement portion, when the pin tail of the locking pin is placed on the return hook plate, the pin tail can contact and abut with the end of the placement portion, and the return hook can drive the locking pin to move, and the cone head drives the locking pin to pass through the installation to be installed, thereby improving the installation efficiency of the locking pin on the gear protection ring.

[0023] Figure 1 This is a schematic structural diagram of the mounting cone of the gear protection ring, as shown in Figure 1 As shown, and reference Figures 2 to 3 The present invention provides a mounting cone for a gear protection ring. The mounting cone includes a cone rod 100 and a cone head 200. The cone rod 100 includes a handheld operating portion 110 and a mounting portion 120. The cone head 200 is provided with a placement portion 210, a return hook plate 220, and a connecting portion 230. The connecting portion 230 is connected to the mounting portion 120. The placement portion is provided with a placement cavity extending along the axis of the cone head 200. The placement portion is provided with a first notch 211 extending outward from the placement cavity in the radial direction of the cone head 200. The return hook plate 220 is located between the placement portion 210 and the connecting portion 230. The return hook plate 220 and the first notch 211 are arranged opposite each other about the axis of the cone head 200. One end of the return hook plate 220 is connected to the placement portion 210, and the other end is fixedly connected to the connecting portion 230. The width of the return hook plate 220 is smaller than the diameter of the placement portion 210.

[0024] Specifically, the mounting cone is used to mount the locking pin 300 of the protection ring into the mounting hole of the gear protection ring, thereby locking the gear protection ring. The locking pin 300 has a pin head, a pin tail and a pin column.

[0025] Furthermore, the floor of the placement groove 212 is an arc-shaped surface, and the pin of the locking pin 300 is placed in the placement groove 212. The first notch 211 provided in the placement portion 210 is provided along the radial direction of the placement portion 210 and along the length direction of the placement groove 212. The first notch 211 is used to place the pin of the locking pin 300 in the placement groove 212, thereby enabling the locking pin 300 to be quickly installed. Furthermore, the placement groove 212 extends front to back along the axial direction of the placement portion 210. The front end of the placement groove 212 is the front end of the cone head 200. When the locking pin 300 is installed in the placement groove 212, the pin head of the locking pin 300 extends forward from the front end of the placement groove 212, and the pin tail extends successively from the rear end of the placement groove 212.

[0026] Specifically, the return hook plate 220 and the rear end of the placement portion 210 form a return hook, and the tail of the locking pin 300 is placed on the return hook plate 220. Because the width of the return hook plate 220 is smaller than the diameter of the placement portion 210, when the tail of the locking pin 300 is placed on the return hook plate 220, the tail of the locking pin 300 can contact and abut the end of the placement portion 210 (the diameters of both the pin head and the pin tail are larger than those of the placement portion 210). In other words, the return hook can drive the locking pin 300 to move, and the cone head 200 can drive the locking pin 300 through the installation to be installed.

[0027] During operation, the cone head 200 is first inserted into the mounting hole where the locking pin 300 is to be installed, and then the locking pin 300 is installed in the placement groove 212. The pin of the locking pin 300 is installed in the placement groove 212 through the first notch 211, and the tail of the locking pin 300 is located on the return hook plate 220. After the locking pin 300 is installed in the placement groove 212, the cone rod 100 is pulled along the axis of the mounting hole. The cone rod 100 drives the cone head 200 out of the mounting hole. The cone head 200 drives the locking pin 300 synchronously by turning back, and the tail of the pin is pulled out to the other side of the mounting hole, thus installing the locking pin 300 in the mounting hole.

[0028] In this embodiment, if Figure 1 As shown, the operating portion 110 is a horizontal rod, the mounting portion 120 is a vertical rod, and the mounting portion 120 and the operating portion 110 are perpendicular to each other and fixedly connected. The connecting portion 230 is connected to one end of the mounting portion 120.

[0029] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, the thickness of the return hook plate 220 is less than the wall thickness of the placement portion 210. Specifically, the outer wall of the return hook plate 220 is coplanar with the outer wall of the placement portion 210. This configuration of the return hook plate 220 being less than the wall thickness of the placement portion 210 allows the lower rear end of the placement portion 210 to contact the lower side of the pin tail when the pin tail of the locking pin 300 is positioned on the return hook plate 220. This increases the contact area between the return hook and the pin tail, thereby preventing the pin tail from disengaging from the return hook during installation.

[0030] In a further embodiment, the inner surface of the hook plate 220 is an arc-shaped surface. The provision of the arc-shaped surface can improve the stability of the pin tail on the hook plate 220 .

[0031] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, the connecting portion 230 is provided with a plug slot, which is inserted into the mounting portion 120 through the plug slot. The connecting portion 230 is detachably threadedly connected to the mounting portion 120. Specifically, the end of the mounting portion 120 is provided with a plug connector 121, which is provided with threads. The mounting slot and the plug connector 121 threadably mate, thereby threading the connecting portion 230 and the plug slot. Furthermore, the detachable connection between the connecting portion 230 and the plug connector facilitates the replacement of the cone head 200.

[0032] In this embodiment, the cone head 200 includes models of various sizes, and the cone head 200 can be disassembled and replaced through threaded connections to increase the use range of the installation cone and improve applicability.

[0033] In some embodiments of the present invention, Figure 2 and Figure 3As shown, the end of the placement portion 210 connected to the return hook plate 220 is the rear end, and the front end of the placement portion 210 is provided with a tip 213. Specifically, the diameter of the tip 213 gradually increases from front to back, and the diameter of the circumscribed circle at the front end of the tip 213 is smaller than the diameter of the mounting hole. Furthermore, the provision of the tip 213 facilitates the insertion of the cone head 200 into the mounting hole, thereby improving the installation efficiency of the locking pin 300.

[0034] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, an expansion portion 240 is provided on the outside of the placement portion 210. The expansion portion 240 is used to increase and then decrease the diameter of the placement portion 210 from the front end to the rear end along its axial direction, so that the diameter of the middle portion of the placement portion 210 is larger than the diameters at the front and rear ends. Specifically, the provision of the expansion portion 240 can temporarily expand the inner diameter of the mounting hole when the cone head 200 is inserted into the mounting hole, thereby reducing the friction between the inner wall of the mounting hole and the cone head 200 and the pin head when the locking pin 300 passes through the mounting hole with the cone head 200. In other words, the expansion portion 240 can enable the cone head 200 to be quickly inserted into the mounting hole, thereby further improving the installation efficiency of the locking pin 300.

[0035] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications consistent with the principles of the present invention can be directly determined or deduced from the contents disclosed herein without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and deemed to cover all such other variations or modifications.
