Description

Technical Field

[0001] This utility model relates to the field of safety hammer technology, and in particular to a pull-triggered safety hammer. Background Technology

[0002] A car safety hammer, also known as a multi-functional safety hammer, is a tool installed in a car to break the car window and escape in the event of an emergency or disaster. Passengers can use it to break the car window and escape through the window, ensuring the safety of passengers. Currently, safety hammers require a certain amount of force to break the window, which makes it difficult for some children and girls with less strength to break the window easily. They also require a certain amount of space to swing their arms.

[0003] A safety hammer with patent number CN213698609U works by pressing the hammer head against the glass and then pressing down on the housing, which compresses the spring inside the housing to store energy. After pressing down to the bottom, the hammer is released from the other side, transferring kinetic energy to the hammer head to break the glass. Because this type of safety hammer requires the user to apply force directly to the glass with their arm, after the glass breaks, the user's arm may not have time to release the force and may extend towards the broken glass under the residual force, resulting in cuts and lacerations to the hand, which is not safe to use.

[0004] Therefore, it is necessary to propose a pull-triggered safety hammer to improve the safety of the safety hammer and avoid situations where the user's arm is still extended towards the broken glass after the glass is broken. Utility Model Content

[0005] To address the aforementioned issues, this invention proposes a pull-type trigger safety hammer to improve the safety of its use and prevent situations where the user's arm is still extended towards the broken glass after it has been broken.

[0006] This utility model is achieved through the following technical solution:

[0007] This utility model proposes a pull-triggered safety hammer, including a hammer head, a housing, an elastic element, and an impact assembly. The hammer head is fixedly connected to one end of the housing, and one end of the elastic element is fixedly connected to the hammer head and housed within the housing. The impact assembly is slidably connected to the housing, and the other end of the elastic element is fixedly connected to the impact assembly. One end of the impact assembly is housed within the housing and contacts the hammer head. Pulling the impact assembly stretches and stores force in the elastic element. When the impact assembly is released, the contraction force of the elastic element drives the impact assembly to impact the hammer head.

[0008] Furthermore, the hammer head is provided with a connecting post that extends into the housing and is fixedly connected to one end of the housing. One end of the impact assembly is in contact with the connecting post.

[0009] Furthermore, the impact assembly includes an impact post, a sliding cylinder, and a handle. One end of the impact post and one end of the sliding cylinder are fixedly connected to one end of the handle. The other end of the impact post is housed in the sliding cylinder and contacts the hammer head. The other end of the sliding cylinder is slidably connected to the housing. One end of the elastic element is fixedly connected to the impact post.

[0010] Furthermore, one end of the impact column is provided with an impact head, which contacts the hammer head.

[0011] Furthermore, one end of the impact post is provided with a fixing post, and one end of the elastic element is fixedly connected to the fixing post.

[0012] Furthermore, the elastic element is arranged around the impact post.

[0013] Furthermore, a portion of the impact column is housed within the sliding cylinder.

[0014] Furthermore, one end of the sliding cylinder is provided with a limiting snap-fit ​​end, which is slidably connected to the inner wall of the housing.

[0015] Furthermore, the limiting engagement end is provided with multiple limiting protrusions, which are evenly distributed circumferentially. The inner wall of one end of the housing is provided with a blocking step, which blocks the limiting protrusions.

[0016] Furthermore, one end of the handle is provided with a guide groove cutting edge, which is located away from the housing.

[0017] The beneficial effects of this utility model are:

[0018] This invention uses the shell as a hand grip structure. When breaking glass, the hammer head is placed against the glass. Pulling the impact component stretches and stores energy in the elastic element. When the impact component is released, the contraction force of the elastic element drives the impact component to strike the hammer head, allowing the hammer head to receive the kinetic energy from the impact component and transfer it to the glass, thus breaking it. During this process, the user maintains the position of the hammer head with one arm and pulls the impact component with the other. The arm maintaining the position of the hammer head does not need to press most of the force against the glass. After the glass is broken, the arm can be quickly retracted, preventing the arm from extending towards the broken glass due to excess force. In summary, this pull-triggered safety hammer effectively improves the safety of using a safety hammer, preventing the user's arm from extending towards the broken glass with excess force after the glass is broken.

[0027] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will further explain this utility model.

[0028] Please refer to Figures 1-3This utility model proposes a pull-triggered safety hammer, including a hammer head 1, a housing 2, an elastic element 3, and an impact component 4. The hammer head 1 has a conical structure, and the housing 2 is easy for the user to grip. The hammer head 1 is fixedly connected to one end of the housing 2. The elastic element 3 is a tension spring structure, which stretches and stores force when pulled and retracts and resets when released. One end of the elastic element 3 is fixedly connected to the hammer head 1 and is housed inside the housing 2. The impact component 4 is slidably connected to the housing 2, and the other end of the elastic element 3 is fixedly connected to the impact component 4. One end of the impact component 4 is housed inside the housing 2 and contacts the hammer head 1. Pulling the impact component 4 can stretch and store force in the elastic element 3. When the impact component 4 is released, the retraction force of the elastic element 3 can drive the impact component 4 to impact the hammer head 1.

[0029] In this embodiment, the user can use the housing 2 as a hand grip structure. When breaking the glass, one hand holds the housing 2 and places the hammer head 1 against the glass, while the other hand pulls the impact component 4 to stretch and store the elastic element 3. When the impact component 4 is released, the elastic element 3 can be used to drive the impact component 4 to impact the hammer head 1, so that the hammer head 1 receives the kinetic energy of the impact component 4 and transfers it to the glass to break it. During this process, the user maintains the position of the hammer head 1 with one arm and pulls the impact component 4 with the other arm. The arm that maintains the position of the hammer head 1 will not press the glass excessively, that is, the arm that maintains the position of the hammer head 1 does not need to press most of the force on the glass. After the glass is broken, the arm can be quickly retracted, and the arm will not extend into the broken glass due to excessive residual force.

[0030] In summary, this pull-type trigger safety hammer can effectively improve the safety of using the safety hammer and prevent the user's arm from reaching towards the broken glass while still having residual force after the glass has been broken.

[0031] In this embodiment, the hammer head 1 is provided with a connecting post 11, which extends into the housing 2. The connecting post 11 is fixedly connected to one end of the housing 2, and one end of the impact component 4 contacts the connecting post 11. The connecting post 11 is provided to improve the stability of the connection with the housing 2, and also to allow the impact component 4 to impact inside the housing 2, so as to transfer kinetic energy to the end of the hammer head 1.

[0032] In this embodiment, the impact assembly 4 includes an impact post 41, a sliding cylinder 42, and a handle 43. One end of the impact post 41 and one end of the sliding cylinder 42 are fixedly connected to one end of the handle 43. The other end of the impact post 41 is housed within the sliding cylinder 42 and contacts the hammer head 1. The other end of the sliding cylinder 42 is slidably connected to the housing 2. One end of the elastic element 3 is fixedly connected to the impact post 41. When the impact assembly 4 is pulled, the user holds the handle 43 and pulls it backward. At this time, both the sliding cylinder 42 and the impact post 41 move backward, and the elastic element 3... The elastic element 3 is stretched and stores energy. The greater the stretching distance, the longer the stretching distance of the elastic element 3 and the more energy is stored. However, it cannot exceed the elastic limit. The sliding cylinder 42 provides a sliding guide structure and the maximum elastic limit of the stretchable elastic element 3, so that the impact column 41 can move smoothly along the axis of the housing 2. When the handle 43 is released, the impact column 41 is pulled by the contraction force of the elastic element 3. Under the guiding sliding action of the sliding cylinder 42, the impact column 41 can directly strike the connecting column 11, so that the kinetic energy is transferred to the end of the hammer head 1 and the glass is broken.

[0033] In this embodiment, one end of the impact column 41 is provided with an impact head 411. The impact head 411 is a metal structure with a certain weight, which can provide sufficient kinetic energy during impact. The impact head 411 is in contact with the hammer head 1. When the handle 43 is not pulled, the impact head 411 is in contact with the connecting column 11. After the handle 43 is pulled and released, the impact head 411 impacts the connecting column 11 under the contraction force of the elastic member 3.

[0034] In this embodiment, one end of the impact post 41 is provided with a fixed post 412, one end of the elastic member 3 is fixedly connected to the fixed post 412, one end of the fixed post 412 is fixedly connected to the handle 43, and the other end of the fixed post 412 is fixedly connected to one end of the elastic member 3. When the handle 43 is pulled, the fixed post 412 pulls one end of the elastic member 3 backward to stretch it, so that the elastic member 3 is stretched and stores force.

[0035] In this embodiment, the elastic element 3 is arranged around the impact post 41. The elastic element 3 is a coiled tension spring. The way it is installed around the impact post 41 can save installation space and ensure balanced force distribution.

[0036] In this embodiment, a portion of the impact post 41 is housed within the sliding cylinder 42. The sliding cylinder 42 provides a sliding guide structure for the impact post 41 and also houses the impact post 41 to save installation space.

[0037] In this embodiment, one end of the sliding cylinder 42 is provided with a limiting snap-fit ​​end 421, which is slidably connected to the inner wall of the housing 2. When the sliding cylinder 42 is installed in the housing 2, the limiting snap-fit ​​end 421 is inserted into the housing 2. After insertion, the limiting snap-fit ​​end 421 will be slidably connected to the inner wall of the housing 2 to ensure that the impact column 41 can move along the central axis of the housing 2.

[0038] In this embodiment, the limiting engagement end 421 is provided with multiple limiting protrusions 4211, which are evenly distributed circumferentially. The inner wall of one end of the housing 2 is provided with a blocking step 21, which blocks the limiting protrusions 4211. The cooperation between the limiting protrusions 4211 and the blocking step 21 is to prevent the sliding cylinder 42 from disengaging from the housing 2 due to excessive pulling force when the handle 43 is pulled. The blocking step 21 is also the maximum elastic stretching distance of the elastic element 3.

[0039] In this embodiment, one end of the handle 43 is provided with a guide groove cutting blade 431. The guide groove cutting blade 431 is away from the housing 2. The guide groove cutting blade 431 is used to cut the rope. When cutting, the rope can be inserted into the guide groove cutting blade 431 for cutting, which can improve the positioning effect of cutting.

[0040] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
